Abstract

The invention relates to a security punch for a forging press. The security punch comprises a punch body and a punch casing, wherein the punch body comprises a primary rod and a secondary rod; the punch casing comprises an upper casing and a lower casing; bulges are formed between the upper casing and the lower casing; a through hole is formed in the upper casing; an installation groove group is arranged in the punch casing and comprises a security rod installation groove and a punch installation groove; a security rod is arranged in the security rod installation groove; a security pin is arranged on the security rod; the punch is arranged in the punch installation groove; and the secondary rod is connected with the security rod at one end. According to the security punch, the pressure bearing capacity is high, and the security function is achieved at the same time; and the situation that the punch is damaged or the whole machine is damaged due to overloaded pressure borne by the punch is avoided.

Description

technical field [0001] The invention relates to a safety punch for a forging press, which belongs to the technical field of tap shank reduction processing. Background technique [0002] A tap is a tool for processing internal threads. According to the shape, it can be divided into a spiral tap and a straight-edged tap. The handle of the tap is forged and thinned by a forging machine, also called a shrinking handle; the punch is a part of a stamping die in a mechanical tool. Metal parts, also called punching rods, punching needles or punches, are installed on stamping dies for continuous punching and punching operations, so that the processed materials are separated or plastically deformed, so as to obtain the required finished or semi-finished products. [0003] In the prior art, forging presses for processing taps and shrinking shanks, the punches on the punches will be subjected to overload pressure due to the hardness inside the forging or other failure reasons. As the ma...
