Problems solved by technology

[0006] The purpose of the present invention is to solve the existing small-head screws. When using a tooth rolling machine to rub teeth, due to the small diameter of the head, the lower support surface is not enough, the blanking is not smooth, the nail bridge is jammed, and the screw is skewed. The problem of thread processing with vibrating plate + nail bridge blanking

Abstract

The invention relates to a small-head screw thread rolling device. The device comprises a thread rolling mechanism, a sending mechanism arranged on the right side of the thread rolling mechanism, a feeding mechanism with one end connected with the feeding mechanism and the other end connected with the right side of the thread rolling mechanism and a discharging mechanism arranged below the left side of the thread rolling mechanism, and further comprises anti-inclination mechanisms arranged in the feeding mechanism and the thread rolling mechanism and a blocking mechanism arranged at the inletend part of the thread rolling mechanism; and each anti-inclination mechanism comprises a blocking piece close to one side of a small-head screw, a supporting piece with which the lower end face of the small-head screw is padded, a first pressing rod pressing on the upper end face of the small-head screw and a second pressing rod pressing on the upper end face of the small-head screw, wherein theblocking piece, the supporting piece and the first pressing rod are used for positioning the small-head screw during feeding and preventing the small-head screw from inclining and bouncing, and the second pressing rod is arranged on the upper side of the thread rolling mechanism and used for preventing the small-head screw from inclining and bouncing in the thread rolling process. According to thescheme, the problem that the small-head screw cannot be discharged is solved, and the working efficiency of thread rolling machining and the product percent of pass are improved.

Description

technical field [0001] The invention relates to the field of screw processing, in particular to a small-head screw thread rubbing device and an anti-slant thread rubbing method. Background technique [0002] For existing standard cap screws, the diameter of the screw head is larger than the nominal diameter of the screw. When the gap between the head diameter and the nominal diameter is large, the method of vibrating plate + nail bridge blanking is usually used for thread processing. [0003] However, if figure 1 As shown, it is a cylindrical head machine screw. The screw is characterized in that the head diameter D1 is equal to the nominal diameter D2 of the thread (the nominal diameter of the thread, except that the inner diameter of the pipe thread is the nominal diameter of the pipe thread, the diameter of other threads Nominal diameter, the major diameter of the thread is the nominal diameter), and the thread length requires a relatively small tolerance, we call this k...
