Description

Technical Field

[0001] The utility model relates to the field of bar processing, in particular to an extrusion die used for processing titanium alloy bars. Background Art

[0002] Extrusion die is an important component of precision plastic volume forming technology. Extrusion die refers to a die into which titanium alloy blank is placed in a cold state. Under the action of strong pressure and a certain speed in the cavity, titanium alloy is forced to be extruded from the cavity, thereby obtaining an extruded part of desired shape, size and certain mechanical properties. Obviously, extrusion processing relies on the die to control the flow of titanium alloy and relies on the large-scale transfer of titanium alloy volume to form parts. Extrusion is to place the titanium alloy blank in the extrusion cavity, and at room temperature, apply pressure to the blank through the punch fixed on the press to make the titanium alloy blank plastically deformed to obtain a part. Extrusion die is generally used when processing titanium alloy bars. Due to the large variety of processed products, the die needs to be replaced. Due to the danger in the use of the die, the die will be fixed, but it is not convenient to disassemble the die after it is fixed, so it is not convenient to replace the die. In summary, the problems existing in the prior art are: there are many types of existing processed products, and it is not convenient to replace the die during use.

[0003] According to the patent application number CN202222025363.3, an extrusion die for titanium alloy bar processing includes a stamping table and a die, wherein the die is located at the top of the stamping table, and the left and right sides of the die are fixedly connected with a first dovetail block, and the left and right sides of the top of the stamping table are provided with a shell, and the right side of the inner cavity of the right shell is provided with a spring, and the left side of the inner cavity of the right shell is provided with a positioning assembly used in conjunction with the dovetail block, and the front and rear sides of the right shell are provided with a limit assembly used in conjunction with the positioning assembly. By setting the first dovetail block, the positioning assembly and the limit assembly for coordinated use, the user pushes the push block, the push block drives the push column to move, the spring is squeezed, the push column drives the transmission column to move, the transmission column drives the transmission block to move, the transmission block drives the connecting block to move, and the connecting block drives the second dovetail block to move, which solves the problem that there are many types of existing processed products and it is inconvenient to replace the mold during use.

[0004] There are still some shortcomings in this patent application. After the mold is replaced, there is no design to limit the push block. It is necessary to manually push the push block to fix the mold. It is very dangerous for workers during the die pressing operation. Therefore, an extrusion die for titanium alloy bar processing is needed to solve this problem. Utility Model Content
