Hot punching automatic forging and pressing compound die structure and hot punching automatic forging and pressing compound die process

Abstract

The invention relates to a hot punching automatic forging and pressing compound die structure and a hot punching automatic forging and pressing compound die process. The hot punching automatic forging and pressing compound die structure comprises an upper die, a lower die and a demolding mechanism, the upper die is an open die, the lower die is a spring die, the upper die and the lower die are extruded and closed through a punch press to perform forging and pressing forming on a metal brass material, and the demolding mechanism separates a formed blank from the upper die and the lower die. According to the hot punching automatic forging and pressing compound die structure, a complex discharging mechanism is omitted, the pre-locking die force is increased, a traditional half die structure is divided into two parts, feeding ports are reduced, the service life of the die is prolonged, stamping products are free of flashes due to the fact that a die cavity is mounted, the manual trimming procedure is omitted, the purpose of finish machining visual sorting automation is achieved, hot punching automation type composite die forging operation can be achieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of red punch forging, in particular to a red punch automatic forging composite die structure and its technology. Background technique [0002] With the development of equipment manufacturing, robotics, automobile manufacturing, electronic technology and automation technology, especially the "Made in China 2025" planning automatic red punch is moving towards high processing adaptability, high production efficiency, highly automated control, and high economic benefits The current development of the mold mechanism for automatic red punching machines has the following problems: 1. Some hardware products do not need to be brought out through the upper mold, and the efficiency of the lower mold clamping and discharging is low and complicated, so that automation or automation efficiency cannot be realized Low; 2. Mold, mold frame, and main slider. In the stamping process below, foam, impurities, and oil are deposit...

[0002] With the development of equipment manufacturing, robotics, automobile manufacturing, electronic technology and automation technology, especially the "Made in China 2025" planning automatic red punch is moving towards high processing adaptability, high production efficiency, highly automated control, and high economic benefits The current development of the mold mechanism for automatic red punching machines has the following problems: 1. Some hardware products do not need to be brought out through the upper mold, and the efficiency of the lower mold clamping and discharging is low and complicated, so that automation or automation efficiency cannot be realized Low; 2. Mold, mold frame, and main slider. In the stamping process below, foam, impurities, and oil are deposited on the mold, mold frame, and main slider, resulting in product defects, and the mold cannot be well cooled and lubricated. The extrusion model has rounded corners, so it needs to be replaced frequently; 4. The main slider slides into the mold frame by self-generated gravity, without pre-clamping force, resulting in uncontrollable product flash
