Socket head cap screw processing technology

Abstract

The invention discloses a socket head cap screw processing technology. The socket head cap screw processing technology is characterized by mainly comprising the following steps: (1) head beating; (2) forced bundling: placing a workpiece obtained in the step (1) in a first station die and forcedly bundling to obtain a threaded rod part with a shaft shoulder; (3) pre-upsetting: carrying out head pre-upsetting treatment on the workpiece obtained in the step (2) through a second station die; (4) re-upsetting and internal and external chamfering: carrying out head re-upsetting treatment on the workpiece obtained in the step (3) through a third station die; (5) inner hexagon hole punching and forming: punching an inner hexagon hole in the workpiece obtained in the step (4) through a fourth station die and forming; (6) thread rolling: processing threads on the threaded rod part by using a thread rolling machine; and (7) heat treatment. The invention aims to provide a hexagon socket head shoulder screw manufacturing technology which is convenient to process and high in production efficiency and can guarantee high-precision standard requirements of the product.

Benefits of technology

This patented process allows for easy handling of threaded components without compromising their quality or precision during manufacturing. It also improves the overall performance of these threads by ensuring they have high-quality surfaces that meet strict specifications while maintaining precise dimensions.

Problems solved by technology

In this patented method described in detail during manufacturing processes used to machine hexagon-shaped socket heads with nut caps that were previously made from wood or plastic material, it was found that these methods resulted in poorly finished products due to uneven surface finishes caused by imperfections such as cracks along their edges when turned into threads. Additionally, current techniques involve multiple steps involving cutting off excessive portions at different stages before attaching them onto other components like bolts or nuts. These technical problem addressed through previous researchers has been how to improve upon existing technology without compromising its effectiveness overall.
