A kind of counterweight type blanking buffer device for extruder and counterweight control system

Abstract

The invention discloses a counterweight type blanking buffer device for an extruder and a counterweight control system, and relates to the technical field of extruder blanking. The residual material at the bottom guides the buffer mechanism, and the bottom of the blanking channel of the residual material guide buffer mechanism is provided with a buffer component. The buffer component includes a blocking part and a transition part. The bottom of the blanking channel can pass the area of ​​the remaining material, and at the same time, the blocking part buffers the remaining material impacted by it, and after buffering, the counterweight end arranged on the blocking part is used to reset. In the present invention, two ways of buffering are realized for the residual materials with different sizes and weights, which not only does not affect the circulation of the lighter and smaller residual materials, but also can effectively buffer the larger and heavier residual materials. The reset blocking part can not only buffer, but also will not affect the smoothness of blanking.

Description

technical field [0001] The invention relates to the technical field of extruder blanking, in particular to a counterweight type blanking buffer device for an extruder and a counterweight control system. Background technique [0002] The ingot holding barrel in the extruder can cooperate with the hydraulic cylinder to extrude aluminum rods or other cylindrical materials. During the extrusion process, the aluminum rods are shaped by the extrusion die to extrude aluminum profiles of specific shapes. When changing the aluminum rod, there will be some residual material at the die mouth on the extrusion die, which needs to be cut off with a cutter. It is relatively large, relatively heavy, and the blanking position is relatively high (the blanking height is generally 1-5 meters high), so that the general blanking device is not decelerated enough, and the falling remaining material is easy to smash the remaining material transportation line, and the remaining material is cut off. ...

AI Technical Summary

Problems solved by technology

[0002] The ingot barrel in the extrusion machine can cooperate with the hydraulic cylinder to extrude aluminum rods or other cylindrical materials. During the extrusion process, the extrusion die is used to shape the aluminum rods to extrude aluminum profiles of specific shapes. When changing the aluminum rod, there will be some residual material at the die opening on the extrusion die, which needs to be cut off with a cutter. It is relatively large, heavy, and the blanking position is relatively high (the blanking height is generally 1-5 meters high), so the deceleration of the general blanking device is not enough, and the falling residual material is easy to damage the residual material transportation line. The material is not fixed, and there will be lighter and smaller residual materials

[0003] In the prior art, the falling surplus material will be buffered through the resistance effect. In the Chinese patent publication number: CN208960655U, a steel rod receiving device is disclosed, which solves the problem that the steel rod slides from the drum to the receiving rack on the ground. When it hits the receiving rack, the impact force is large, and the bottom of the steel bar is prone to deformation and damage. The main points of the technical plan are that it includes the drum, the bracket below the drum and the base of the fixed bracket. The upper end surface of the bracket is smaller than the end surface of the drum. , the base is connected to the center of the bracket with a vertical support column, and a number of baffles are evenly arranged on the outer peripheral side of the bracket to slow down the impact force of the steel bar sliding down from the roller

[0004] However, in general, devices that buffer through resistance need to consider the circulation of lighter and smaller residual materials, because lighter and smaller residual materials will be affected by resistance and cannot circulate
