Semicircular bolt forming equipment and process thereof

Abstract

The invention discloses semicircular bolt forming equipment and a process thereof, and particularly relates to the technical field of bolts. The semicircular bolt forming equipment comprises a box body, wherein a hydraulic mechanism is connected to the top end of the inner side of the box body through screws; a fixing frame is installed below the hydraulic mechanism; a connecting base is arranged below the inner side of the fixing frame; a movable punch is installed below the connecting base; a discharging hole is formed in the inner side of the movable punch; a feeding mechanism is arranged above the connecting base; a sliding mechanism is installed at the bottom end of the inner side of the box body; a workbench is arranged above the sliding mechanism; and a fixing groove is formed in the upper surface of the workbench. According to the semicircular bolt forming equipment and the process thereof provided by the invention, a T-shaped cushion block and a strong spring are arranged, when the strong spring is used, strong support is provided when a movable punching core does not abut against the T-shaped cushion block, so that the pre-forming effect is achieved; and the strong spring is stable in stress, so that the situation that the single side is stressed in the deformation process is avoided, and a pre-forming shape structure is more stable.

Description

technical field [0001] The invention relates to the technical field related to bolts, in particular to a semicircular bolt forming equipment and a process thereof. Background technique [0002] A bolt is a mechanical part, a cylindrical threaded fastener with a nut, a type of fastener consisting of a head, a screw, and a cylindrical body with external threads, which needs to be matched with a nut for tightening Fixedly connect two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, the bolt connection is a detachable connection. Ordinary bolts are manufactured according to The accuracy can be divided into three grades: A, B and C. A and B grades are refined bolts, and C grades are rough bolts. For connecting bolts for steel structures, unless otherwise specified, they are generally ordinary rough C grade bolts. There are differences in the processing methods of different ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a half-round bolt forming equipment and its process, which solves the problem of the half-round bolt forming equipment used in modern times. During the cold heading forming process of the half-round head bolt at the present stage, due to the problem of the one-shot structure, the The size of the first punch preform is not in place, the height is too high, and the forming is unstable; when the second mold is finally formed, the size is unstable, there will be steps in the hexagonal hole, and it is easy to slip, etc.
