Horizontal bolt cold heading forming machine

Abstract

The invention discloses a horizontal bolt cold heading forming machine. According to the horizontal bolt cold heading forming machine, the structure can be effectively simplified, and actual production and manufacturing is facilitated; meanwhile, operation is convenient, and bolt cold heading process steps can be effectively simplified; and in addition, the problems that a bolt is extruded and damaged and even an ejection mechanism of bolt cold heading equipment is damaged due to the fact that the bolt cold heading process steps get wrong can be effectively solved. The horizontal bolt cold heading forming machine comprises a bottom frame, a left support and a right support which are arranged on the bottom frame, a translation support, a translation executing mechanism for driving the translation support, a rotating module rotationally arranged on the left support through a horizontal shaft rod, a stud limiting hole formed in the rotating module, a reference block and a stop block whichare arranged on the left support, a stamping die arranged on the translation support, a bolt head forming hole formed in the stamping die, a clamping groove formed in the outer side face of the rotating module as well as an elastic clamping hook arranged on the translation support.

Description

technical field [0001] The invention relates to bolt processing equipment, in particular to a horizontal bolt cold heading forming machine. Background technique [0002] Cold heading is a forging method that uses a mold to upset (usually local upsetting) a metal bar at room temperature. It is usually used to manufacture the heads of screws, bolts, rivets, etc., which can reduce or replace cutting processing. The current bolt cold heading equipment generally needs to be equipped with an ejection mechanism, and its cold heading process generally includes the following four steps, [0003] First, put the rod on the fixed mold; [0004] Second, the cold heading equipment controls the die to be close to the fixed die, and performs cold heading to make the head of the bolt cold-headed in the forming hole, and then the die is separated from the fixed die; [0005] Third, through the cylinder of the ejector mechanism, the cold-headed bolts left on the fixed mold are ejected; [0...

AI Technical Summary

Problems solved by technology

[0007] At present, this kind of bolt cold heading process steps is not only complicated, but also requires operators to follow the above steps. Once an error occurs in the cold heading process steps, the bolts will be squeezed and damaged, and even the ejection mechanism of the bolt cold heading equipment will be damaged. The problem of being damaged, for example, in the process of controlling the die to be close to the fixed die and performing cold heading, the operator makes an operation error to control the ejection of the cylinder of the ejector mechanism, or when the operator controls the ejection of the cylinder of the ejector mechanism, the operator If there is an operation error to control the die close to the fixed die and perform cold heading, the bolts will be squeezed and damaged, and even the ejector rod of the ejector mechanism will be damaged.

[0008] In order to solve the above problems, the inventor of the present application submitted the application number 2020108222246 on August 16, 2020, and the name of the invention is bolt horizontal forming equipment. During the process, it was found that the horizontal bolt forming equipment in this case had a complicated structure, which was not convenient for actual production.
