Tooth knife punching die structure for knife bending machine and knife bending machine

Abstract

The invention discloses a tooth knife punching die structure for a knife bending machine and the knife bending machine. The die structure comprises a pillow-position die, a bottom die, a bottom die drive mechanism and a punching male die; and the lower end face of the pillow-position die is provided with groove which penetrates the front and the rear and which matches the punching male die in width, the upper end face of the bottom die is provided with a protruding block which matches the groove in width, the pillow-position die and the bottom die are disposed in an up-down relative manner, the groove and the protruding block are disposed in a matching and sleeving manner to form a die hole matching the punching male die in width, and the bottom die is driven by the bottom die drive mechanism to move in the vertical direction so that the height of the die hole relative to a blade is changed. The pillow-position die and the bottom die are adopted to together form a mother die, the bottom die slides relative to the pillow-position die so that the height of the die hole relative to the blade is adjustable; and the bottom die and the pillow-position die form the die hole adopting a groove-block matching mode, so the blade can be guaranteed to be completely abutted except for at a punching position, tooth knife height adjustments are achieved, and the punching effect is guaranteed at the same time.

Description

technical field [0001] The invention relates to the technical field of a machete machine, in particular to a punching die structure with a gear cutter for a machete machine and a machete machine. Background technique [0002] The machete machine is widely used in the production of high-precision knife templates such as electronics and optoelectronics. Today's electronics, printing and packaging industries are developing rapidly, and as a supporting industry - die-cutting board (mold cutting) processing industry has been greatly developed. With the increase of market share, more and more enterprises and funds have entered the industry, which has caused the die-cutting industry, which was originally very profitable, to enter a difficult situation. However, in the market competition where price is the main factor, in addition to reducing production costs, improving production efficiency is also an important factor for winning the competition. As one of the two core equipments...

Problems solved by technology

In addition, frequent mold adjustments due to changes in the width of the gear cutter, and the contact gap between the blade and the mold have a great impact on the punching accuracy when the gear cutter is punching, which also plagues those skilled in the art.
