Vertical cold heading forming equipment for bolts

Abstract

The invention discloses vertical cold heading forming equipment for bolts. According to the vertical cold heading forming equipment for the bolts, the structure as well as cold heading process steps of the bolts can be effectively simplified; and meanwhile, the problem that the bolts are extruded and damaged due to the fact that the cold heading process steps of the bolts get wrong can be effectively solved. The vertical cold heading forming equipment for bolts comprises a bottom frame, a stand column arranged on the bottom frame, an upper support fixedly arranged to the upper portion of the stand column, a lifting support located below the upper support, a lifting executing mechanism arranged on the upper support and used for lifting the lifting support, a stamping die arranged on the lifting support, a bolt head forming hole formed in the lower surface of the stamping die, a rotating module rotationally arranged on the bottom frame through a horizontal shaft rod, a stud limiting holeformed in the rotating module, a reference block arranged on the bottom frame and used for positioning the rotating module, a clamping block arranged on the outer side face of the rotating module aswell as an elastic clamping hook arranged on the lifting support.

Description

technical field [0001] The invention relates to bolt processing equipment, in particular to a vertical cold heading forming equipment for bolts. 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; ...

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 this application submitted the application number 2020108222250 on August 16, 2020, and the name of the invention is a vertical bolt forming machine. 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.
