This connection forms two cushions, specifically:
during stamping operation, the spring is firstly stressed, and a first buffer is formed under the action of the elastic force of the spring. After the forming plate moves downwards under the action of the stamping head, the buffer plate assembly is stressed to form a second buffer.
It can be seen that this significantly improves the cushioning properties.
In the connecting mechanism of the guide post and the forming plate in the thermal forming stamping die, the lower end of the positioning head is provided with a concave spring seat, and the upper end of the spring is embedded in the spring seat.
The spring end is stabilized by the spring seat.
Compared with the prior art, this coupling mechanism of guide post and profiled sheeting among thermoforming stamping die is because the profiled sheeting is stable to be connected in the guide post upper end, consequently, among the punching press operation process, the profiled sheeting is main atress spare, can effectively improve its stability. In addition, the forming plate can be independently replaced after being damaged, and the use cost of the die is lower.
Meanwhile, a first buffer is formed under the action of the spring, a second buffer is formed under the action of the buffer plate assembly, and the structure can avoid rigid contact between stamping and a die in the stamping process, so that the stability of the stamping die is further improved.
In addition, the main parts are positioned between the forming plate and the guide post, the structure is compact, and the high-strength steel plate has high practical value.
