Basic Knowledge of Dental Plate and Answers to Frequently Encountered Adjustment Questions

Basic knowledge of 1. dental plate

1. Feeding area: that is, in the process of adjusting the machine, the light nail is fed to the compacted part. In order to facilitate feeding, anti-slip teeth are often engraved on the feeding area and shaping area;

2. Shaping area: the part where the light nails squeeze and reshape after passing through the feeding area;

3. Forming area: after the light nail passes through the feeding area and the shaping area, the light nail is extruded into the screw according to the angle of the tooth groove, tooth front and sharp tail of the tooth plate; 4. Discharging area: the part of the screw after the screw is formed;

4. Back angle and elevation angle: It is the part of the pointed tail tooth plate that is cut and shaped by the sharp mouth. The size of the dorsal angle is the key to control the amount of material fed into the tip. Large dorsal angle feeds more and small dorsal angle feeds less. Elevation angle is the key to cusp shaping and cusp shaping. If the elevation angle is lowered, it will cause tailing and the tail will not be cut cleanly. If the elevation angle is too high, it will cause tip breaking and premature cutting of light nails;

Incision: the part where the back corner intersects with the tip and tail of the dental plate is required to be very sharp. If the incision is too blunt, the material will be cut continuously, resulting in tailing and inconsistent tail tip formation;

6, tooth depth: the depth of the screw tooth front, tooth depth is the key to control the outer diameter of the screw;

7, tooth mountain angle: that is, the angle of the screw tooth front. Special screw tooth mountain angle has special regulations, C/B fiberboard nail tooth mountain 40 degrees; BA round tail screw general tooth mountain angle 47.5 degrees; General triangular double wire self-tapping tooth mountain angle 45 degrees;-general machine tooth tooth mountain 58~60 degrees; The angle of the tooth mountain is also the key to control the outer diameter of the screw.

8. Tail angle: that is, the angle of the tail tip of the screw. Generally, the tail tip of ordinary self-tapping screws is between 40 degrees and 50 degrees. Special screws have special regulations, such as wallboard nails and fiberboard nails. The tip is between 20 degrees and 30 degrees. Machine microphone screws are generally between 80 degrees and 90 degrees. Sometimes customers will specify the tail tip angle;

9, chamfer: that is, the feeding area and shaping area are milled very sharp and sharp during the production process of the dental plate, so as to facilitate feeding. If the chamfer is too sharp, the dental plate will not be wear-resistant; if the chamfer is too blunt, the plane of the tail feeding area is too large, the screw forming is very difficult, and the outer diameter will not be large enough; if the chamfer feeding area is worn too much, it is easy to cause insufficient screw forming, insufficient screw diameter and slippage.

10. Anti-slip teeth: that is, the tooth patterns specially carved on the feeding area and forming area of the tooth plate by the light nail during the feeding and forming process in order to prevent slipping. If the anti-slip teeth are shallow, it will cause slipping. If the anti-slip teeth are deep, it will easily cause the screw bottom diameter to be unsmooth, the tooth front is not bright, and even the outer diameter of the screw is small due to blocking the extrusion of the light nail;

The height of the sharp tail: the distance between the tooth surface of the dental plate and the cutting edge, which is generally half of the bottom diameter of the screw. If the height of the sharp tail is too high, the screw incision will collide and the screw forming will be insufficient. The sharp tail is high. Too low will cause the tail to cut and tail.

11) Not wear-resistant

Analysis of common problems and treatment measures:

1) broken tip: a, broken tip is very serious,-generally, the elevation angle of the dental plate is too high, as long as the diamond file is used to trim it lower (it is best to have non-slip teeth at the point), try the dental plate again, trim it several times and try several times more. B, broken tip is not very serious, general analysis of three reasons: 1 elevation angle upper groove opening is not large enough, use a triangular diamond file to file along the direction of the tooth groove. If the elevation angle is a little higher, use a diamond file to trim it lower. 3 elevation angle. The upper anti-skid teeth are not deep enough or the elevation angle is worn too much. Use a thimble to grind some anti-skid teeth into a "one-" shape on the grinding wheel. C, broken tip because the wire material is too hard and broken tip, it is necessary to improve the wire material. D, broken tip because the twisted screw is too large and the optical nail is too long, start with controlling the length of the optical nail.

2) tailing: a, front tail: that is, the tip of the screw has a pin-like tail tip, which cannot be cut cleanly. this is easy to happen when the nail tip of the wall panel requires a very sharp screw to be formed. the treatment measure is to use a gold steel file to trim the incision sharper along the direction of the back angle to facilitate cutting. B, flat tail, that is, there is a lot of material at the tail that cannot be cut off, general analysis has the following reasons: 1. The upper tooth groove in the elevation angle is too wide and deep, and there is too much material to be fed; 2 The angle of back angle repair is too small and there is too much material to be fed. In these two cases, a gold steel file is used to push the back angle in the direction of the back angle at the elevation angle, so that the back angle angle is increased and less material is fed. In general, the first reason is difficult to repair, the second one is relatively easy to repair. 3 When adjusting the machine, it is also possible to loosen the teeth so that less material can be added to the nozzle. For example, the feeding end is loose and the forming area is tight, which can also solve the tailing problem. Controlling the length of the light nail is also of great help to solve the tailing problem.

It is very helpful to control the length of the light nail to solve the problem.

4), heavy teeth: generally, there are the following situations: a, when adjusting the machine, the tooth pattern is not very good, when the thread of the light nail is extruded, it is most likely to cause heavy teeth, try to move the moving plate up and down several times more,-generally, this problem can be solved; On the fourth page, a total of 7 hectares of B, two pieces of dental plate adjustment machine are not placed on the same side will also cause uneven extrusion, it is easy to cause heavy teeth; C, when adjusting the machine, the sliding surface gap of the moving plate machine is too large, and it is also easy to cause heavy teeth when squeezing. D, when adjusting the machine, the feeding area is too tight, which is also easy to cause heavy teeth; E, the dental plate anti-skid teeth are carved too deeply. At this time, the treatment is to use a triangular diamond file to repair the burrs blocking the anti-skid teeth on both sides of the tooth groove in the groove to reduce friction; F, tooth plate two chamfer width, depth is inconsistent, then can only return to the tooth plate manufacturer repair (this situation

very few casts).

5), the bottom diameter is not smooth: the reason is basically the same as that of heavy teeth, but the fourth reason is that the feeding area of the adjusting machine is too tight to account for the absolute proportion. it is suggested that the feeding area should be loosened and the forming area should be tightened when adjusting the machine, so that the service life of the screw bottom diameter, outer diameter and gloss dental plate should be greatly improved;

6), the outer diameter is not large enough: a, the anti-skid teeth in the tooth groove feeding area and the shaping area are too heavy to affect the screw forming. within 0.04MM, it is recommended to use a triangular file diamond cutter to smooth the anti-skid teeth along the tooth groove direction, which has certain influence on the tooth diameter; B, within 0.04MM, adjust the machine by using the machine method of slightly loosening the feeding area and slightly tightening the forming area, it has some influence on the outer diameter. C, when adjusting the machine, the adjustment is too tight, the tooth length is squeezed long, the natural outer diameter becomes smaller, then the problem can be solved by adjusting the loose point; D, after the previous methods have been tried, the outer diameter is still not up to, it belongs to the dental groove depth is not enough, should be returned to the dental plate manufacturer for repair. E, the dental plate wear is too large, the outer diameter is not considered as appropriate, the service life can be scrapped, and the ideal life can be returned to the dental plate manufacturer for repair; Page 5 of 7

7), the outer diameter is too large: it is generally caused by the deep groove, a, within 0.05MM, use oilstone or diamond file to form on the dental plate

The problem can be solved by fixing the low area by 0.01~0.02MM; B, if the outer diameter is too large, analyze the light

Whether the nail is too large beyond the tolerance, whether the main mold wears too fast, change the mold for treatment; C if the above two methods cannot solve the problem, return to the dental plate manufacturer for shallow tooth trimming.

8), slippage: generally there are three reasons: a, the pressure of the adjusting machine is too tight, slightly loose point; B, the adjustment machine is not flat and not aligned with the tooth line, causing slippage, re-flat the tooth plate, aligned with the tooth line can be; D, anti-skid teeth are too shallow, use thimble to grind the anti-skid teeth into "one shape" deeper, generally can solve the problem; if the anti-skid teeth wear too much, the problem cannot be solved with flowers and the dental plate needs to be used. When, return to the dental plate manufacturer to deepen the anti-skid teeth.

9), scraping head; The reasons for the analysis are generally as follows: a, the feeding of light nails is unstable and not vertical; B, the supporting plate and the light nail blanking are not well matched; C, dental plate two pieces are not flat; D, machine gap is too large; E, dental plate right angle is not enough will also cause scraping head; F, tooth grain oblique inconsistent will also cause scraping head. The sixth page, 7 in total

10) chipping: a, whether the dental plate has been repaired with a grinder to grind off the surface layer of the dental plate. B, dental plate trimming position is too small; C, whether the "r" position under the light nail head is too large and too thick, so that the edge of the dental plate is too stressed; D, dental plate heat treatment is too hard, should be returned to the manufacturer for re-heat treatment.

11) non-wear-resistant: a, light nail material is too poor; B, dental plate heat treatment hardness did not meet the standard; Should be returned to the dental plate manufacturer for re-heat treatment.
