Problems solved by technology

In the traditional continuous extrusion wheel cooling method, the cooling medium is far away from the block and the groove of the extrusion wheel, which will make it difficult for the temperature of the extrusion wheel and the block to drop to the temperature range that the extrusion tool material can withstand. This leads to the destruction of the extrusion wheel and the block, making the extrusion process difficult to continue; at the same time, for medium-strength metals like copper, due to the limitation of the temperature rise of the extrusion wheel and the block, the extrusion wheel and the block The cooling effect of the block directly limits the rotation speed of the extrusion wheel in the continuous extrusion machine, which in turn affects the production efficiency and material utilization of the equipment

Embodiment 1

[0026] A continuous extrusion method for directly cooling the surface of the extrusion wheel groove and the retaining block. The cooling of the extrusion wheel or the retaining block is that the liquid cooling medium directly cools the extruded metal surface covered by the extrusion wheel groove or For the outer surface of the block, the direct cooling of the liquid cooling medium is to use the liquid cooling medium to spray directly on the extruded metal or the outer surface of the block covered by the groove surface of the extrusion wheel through the pump source, so as to quickly lower the extrusion wheel and the block. The temperature of the material block, the speed sensor measures the speed of the extrusion wheel, the temperature sensor measures the temperature of the extrusion wheel and the block material respectively, and the measurement signal is input to the PLC programmable controller or industrial control computer, and stored in the PLC and the industrial control mark...

Embodiment 2

[0029] like figure 1 Shown is a continuous extrusion device that directly cools the surface of the extrusion wheel groove and the stopper block. The rotary extrusion wheel 1 is installed on the rotating shaft 2, and the extrusion wheel 1 has a circumferential groove 17. The surface of the circumferential groove 17 of the wheel 1 is covered with extruded metal 18, and the extruded metal 18 completely rotates synchronously with the circumferential groove 17 on the extrusion wheel 1, and the cavity 4 with the arc sealing surface 19 is installed on the shoe seat 6, the blocking block 3 on the cavity 4 goes deep into the circumferential groove 17 of the extrusion wheel 1, and when the extruded metal rod material (not shown in the figure) passes through the compaction wheel 7, it is 1. When the frictional force is driven to the stopper 3, driven by the frictional extrusion force, high temperature and high pressure will be generated, enter the channel 5 of the cavity 4, and extrude t...

Abstract

The invention relates to the field of metal plastic shaping. The invention discloses a continuous squeezing method of directly cooling squeeze wheel race and material stop block surfaces. A squeeze wheel or a material stop block is cooled with the method that liquid cooling medium directly cools the surface of squeezed metal covered by a squeeze wheel groove or the outer surface of the material stop block; before the squeezed metal covered by the squeeze wheel groove rotates to a compaction wheel and the cooling medium contacts the squeezed metal rod material, no cooling medium is left on the surface of the squeezed metal covered by the surface layer of the squeeze wheel. The continuous squeezing method of the invention more effectively lowers the temperature of the squeeze wheel and the material stop block, improves the production rotation speed of the squeeze wheel, improves the production efficiency of the device and improves the utilization ratio of the material and the service life of the squeeze wheel.

Description

[0001] Field: [0002] The invention relates to the field of metal plastic forming, especially a metal continuous extrusion method; in addition, the invention also relates to continuous extrusion equipment. Background technique: [0003] Cooling technology is an essential core technology for continuous extrusion. If the cooling method or cooling effect is not good, the life of the tooling and die will be significantly reduced, which will affect the production efficiency, and even cause the extrusion process to be unable to continue. Patent JP2000051929A greatly improves the production efficiency of continuous extrusion of porous pipe through the cooling technology of the mold; patent WO9602335A1 provides the structure of the continuous extrusion spindle system, which involves the cooling and lubrication of the spindle bearing; patent WO2004073901A1 provides the cavity The method of body induction heating involves the cooling problem of the heater. [0004] However, there are ...
