Vertical type bolt forming machine

Abstract

The invention discloses a vertical type bolt forming machine and aims to provide the vertical type bolt forming machine which is convenient in operation, can effectively simplify the processing stepsof bolt cold heading, and also can effectively solve the problem that due to a mistake made in the bolt cold heading processing steps, the bolt is extruded to be damaged and even an ejection mechanismof bolt cold heading equipment is damaged. The vertical type bolt forming machine comprises an underframe, an elastic piece, a stand column arranged on the underframe, an upper bracket fixed at the upper part of the stand column, a lifting bracket, a lifting actuator for lifting the lifting bracket, a stamping die arranged on the lifting bracket, a bolt head forming hole formed in the lower surface of the stamping die, a reference block arranged on the underframe, a horizontal shaft lever rotatably arranged on the underframe, a rotary module fixed on the horizontal shaft lever, a first gear rotatably arranged on the horizontal shaft lever through a one-way bearing, a second gear rotatably arranged on the underframe and meshed with the first gear, and a vertical rack matched with the second gear.

Description

technical field [0001] The invention relates to bolt processing equipment, in particular to a vertical bolt 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; [0006] Fourth, th...
