Embodiment Construction

[0010] In the figure: the hammer head of a superimposed punching machine consisting of a hammer head and a convex and concave die is provided with a hammer head A (2) and a hammer head B (3) between the punch slide block (1) and the convex and concave die (4). The hammer head A and the hammer head B are installed. The hammer head A is arranged on the upper part of the hammer head B, and the two hammer heads are stacked up and down. When working, the slider of the punching machine impacts the hammer head A, and the hammer head A transmits the punching power to the hammer head B. Since the hammer head B indirectly bears the force, it is ensured that the force point does not deviate from the center, and then the impact force from the hammer head A acts In the punch and die, the punch and die move downward relative to the master die, generating shear stress, and blanking the workpiece into products with high dimensional accuracy.

Abstract

The invention relates to a stacked punch hammerhead comprising hammerheads and a punch die and characterized in that the hammerhead A and the hammerhead B are arranged between a punch sliding block and the punch die, the hammerhead A is arranged on the upper part of the hammerhead B; and the two hammerheads are stacked up and down. The stacked punch hammerhead has simple structure, the hammerhead B does not deviate from a center in any conditions, and a pinching piece has high size precision and high quality.

Description

technical field [0001] The invention relates to a punch hammer, in particular to a stacked punch hammer. Background technique [0002] At present, on a traditional punching machine, a punching machine generally has only one hammer head, which is arranged between the punching machine slide block and the convex and concave dies. When working, the slide block of the punching machine impacts the hammer head, and the hammer head then acts on the punching power to the punch and die, and the punch and die die move downward relative to the mother die, generating shear stress and punching the punching parts. This structure is in the development process of the punching machine has always been dominant. However, in the actual punching process, the strip often slides or vibrates at the moment when the slider of the punch press hits the hammer head, which causes the hammer head to deviate from the center and affects the dimensional accuracy of the punched parts.
