What is the tolerance range of precision screws?
It can be seen from the extrusion process that the screw works under high temperature, certain corrosion, strong wear and high torque. Therefore, the screw must: 1) High temperature resistance, no deformation under high temperature; 2) Wear resistance, long life; 3 ) Corrosion resistance, the material is corrosive; 4) High strength, can withstand large torque, high speed; 5) Good cutting performance; 6) After heat treatment, the residual stress is small, and the thermal deformation is small.

new type of screw includes a fixing object and a screw body composed of a nut, a fixing piece and a screw rod. An outer gear ring is fixedly sleeved on the fixing piece, and a support plate is arranged on the lower side of the outer gear ring. The upper side of the support plate is connected with a mounting frame through an adjustment mechanism, the inside of the mounting frame is connected with the outer gear ring through an anti-drop mechanism, and a mounting plate is fixedly connected to the side of the support plate close to the fixed object, and the mounting plate is clamped The coupling mechanism is connected to the fixture.
Stainless steel bolts refer to bolts made of stainless steel, including stainless steel SUS201 bolts, stainless steel SUS304 bolts, stainless steel SUS316 bolts, and stainless steel SUS316L bolts. The performance grades of stainless steel bolts, studs and studs are divided into 10 grades: from 3.6 to 12.9. The number before the decimal point represents 1/100 of the tensile strength limit of the material, and the number after the decimal point represents 10 times the ratio of the yield limit to the tensile strength limit of the material.
The beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are: in Guangdong Yueluo Hardware Industry Co., Ltd., the rivet fixing mechanism is used to temporarily fix and position the rivet, and the pressure cylinder is used to drive the movement of the final shaft, so that the insertion nozzle can be Insert the rivet located in the rivet fixing mechanism into the product. Guangdong Yueluo Hardware Industry Co., Ltd. adopts mechanical drive and transmission, which has a high degree of automation and high work efficiency.
