Die loading method

Abstract

The invention belongs to the technical field of machines, and relates to a die loading method. The problems that safety is low and noise is large during die loading in the prior art are solved. The die loading method comprises the following steps that 1, a cushion block is placed on a compartment; 2, a bolt ring is screwed into a thread hole in the side face of a die; 3, the upper end of a hook isbuckled to a vehicle, and the lower end of the hook is buckled into the bolt ring; 4, the die is hoisted to the compartment, when the die is not a male die, the front end of the lower side face of the die is aligned to the cushion block, and when the die is a male die, the lower surface of the convex portion of the male die is aligned to the cushion block; 5, a descending button of the vehicle isoperated to drive the die to descend; 6, the descending button of the vehicle is operated for 0.5-1 s; 7, a retreat button of the vehicle is operated by 0.5-1 s; and 8, the steps 6 and 7 are repeatedly executed till the bottom face of the die is completely attached to the compartment. Die loading safety can be effectively improved, and noise is reduced.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a mold loading method. Background technique [0002] For mold manufacturing, the greatest use of mold heat treatment is to further improve the precision of the mold, such as preventing heating oxidation and decarburization, vacuum degassing or degassing, and eliminating hydrogen embrittlement, thereby improving the plasticity, toughness and fatigue strength of the material. Therefore, the molds in the prior art basically all go through a heat treatment process. The heat treatment plant usually allows the transport driver to go to the mold factory to transport the mold back to the factory for processing. After the heat treatment is completed, it is transported back to the mold factory. However, for large-scale punches, when loading the car, the side of the punch is usually sucked with a suction cup, and then the punch is hoisted to the car through the suction cup with a crane. At t...

AI Technical Summary

Problems solved by technology

[0004] 1. The center of gravity of the punch is usually inclined to the side, so when the punch is laid down so that the bottom surface is close to the car, a large manual thrust is required;

[0005] 2. The side area of ​​the punch is small, and the area that the suction cup can absorb is small, and dust, iron filings, and water droplets are easily attached to the suction cup in the workshop, which affects the magnetism between the suction cup and the mold, and the mold is easy to fall off during transportation. Injure the operator or damage the mold;

[0006] 3. When the mold is pushed down on the vehicle, the impact force is very large, which not only causes great wear and tear to the vehicle, but also produces a lot of noise
