Dongguan screw manufacturers follow a new anchor bolt after the anchor is expanded, and through a special chemical adhesive, the screw is firmly cemented on the concrete base plate to cement the wellbore to complete the composite material part of the solid anchor.
Dongguan screw manufacturers have many types of screws, including stainless steel pan-head combination screws, and stainless steel outer hexagonal combination screws. Stainless steel pan-head combination screws refer to stainless steel pan-head screws with stainless steel spring washers and stainless steel flat washers. Three-component, stainless steel outer hexagonal combination screw refers to stainless steel cross recessed hexagon socket bolt with stainless steel shrapnel gasket combination screw, stainless steel combination screw production technology, stainless steel combination screw is made of stainless steel screw wire cold heading, first Punch out the pan head, screw or hexagonal bolt.
In order to simplify the mold structure and save mold materials, the Dongguan screw manufacturer is designed to bend and cut the carrier in the same station. In this station, the front and back working parts of the bending-cutting punch 11 and the concave mold 2 are rounded to complete the bending forming. The left and right working parts have sharp edge structures to complete the separation of the carrier. Therefore, the fitting clearance around the convex and concave molds is different. The unilateral fitting clearance of the convex and concave molds in the front and rear forming parts is 3 mm, and the unilateral fitting clearance of the convex and concave molds at the left and right punching parts is 0.23 mm. In addition to the two floating guide pins 13 installed on the bending-cutting punch 11, a return pin 20 is also installed to act as a lifting and unloading piece. There is an elastic top piece 17 in the cavity of the die, which not only plays the role of top piece but also presses the material, to ensure the safety of the material, reduce the bending and rebound, and improve the quality of the parts.
Two limit posts are used to ensure that the position of the upper die at the bottom dead center is always consistent during punching, to maintain the stability of the upper and lower die holders, and to ensure the parallelism between the discharge plate and the upper and lower die holders. Protect molds and equipment from damage.
The feeding guide of the strip is limited by a single-sided guide plate and a guide block, and the feeding distance is positioned by the straight edge of the special-shaped die hole. When punching the shape waste, it is positioned by two positioning pins 25, bending The forming adopts two floating guide pins 13 for accurate positioning. In order to ensure the size and position accuracy of the parts, the Dongguan screw manufacturer requires that the step error of each step is less than 0.005 mm and the cumulative error of the step distance is less than 0.01 mm after the mold is assembled.
