Adjust the gap between the two washboard, and then tighten and fix it. Adjust the gap between the two plates so that the blank can be pressed tightly. If the gap is too large, the blank will not be rubbed and fall off.

When the thread rolling machine works for a long time, the friction surface between the sliding guide rail and the body guide rail will wear and tear. At this time, the upper and lower washboards will have uneven surfaces, which will cause the rubbing threads to produce inclined lines (that is, screws or bolts cannot be screwed into nuts), and waste threads such as self-tapping screws will be produced. At this time, grinding or scraping is required. Machine to restore the bottom surface and the fixed die groove to the same plane.

For the time being, some thin pads or iron sheets can be appropriately placed on the moving wire washboard to make the two wire washboards in the same plane, but this will make the adjustment complicated and make the product quality unstable. For this reason, when the wear is severe, the better method is to grind or scraper.

The wire washboard is placed in the movable die groove and the fixed die groove, and no thin pad or iron sheet is necessary under the die. It is only necessary to properly adjust the gap between the two washboards and then tighten them firmly. Adjust the gap between the two plates so that the blank can be pressed tightly. If the gap is too large, the blank will not be able to be rubbed and lost.

If the gap is too small, the blank will not be able to enter the gap between the two plates. Similarly, the blank will not be able to rub and lose.

At the same time, adjust the gap between the upper and lower end faces of the two washboard by turning the two fastening bolts and the tightening bolt. If the tightening bolt is tightened a little, the gap between the flat die at the end of the flat die will become smaller, and the gap shall be adjusted to the depth of the rolling thread until it meets the requirements.

The rolling machine uses one rolling head to roll a variety of steel bars.

The thread rolling machine uses cutting and rolling thread to form at one time to achieve the purpose of reinforcing steel bar end and thread processing, which solves the problem of pretreatment of steel bar end before processing and the problem of multiple times of rolling for similar equipment, thus reducing process processing and multiple steel bar handling on site and improving the production and processing efficiency on site. The thread rolling machine can roll steel bars of various specifications by using one thread rolling head, it solves the situation that the same kind of equipment needs one thread rolling head for each specification to process straight thread of steel bar end. The rolling machine adopts internal cooling liquid, which solves the problem of chip removal during rolling processing. The automation strength is high, and the feed stops automatically and resets automatically. The straight thread rolling machine is a special equipment for processing the straight thread head of the steel bar. The end of the steel bar is rounded by stripping the ribs, and then the steel bar is rolled with three hollow thread rolling wheels to achieve the straight thread forming of the steel bar. Quality requirements.
