Problems solved by technology

In the existing mounting process, the interference fit parts are assembled by manual force pressing or using a resistance heating device to shape and deform the alloy, but manual force pressing is easy to cause damage to the assembly parts, and the quality of mounting cannot be guaranteed , the use of resistance heating devices is costly to control, and the connecting wires during resistance heating are directly exposed to the controller, which poses a safety hazard, and it is easy to oxidize and cause circuit breaks, etc.

Abstract

The invention relates to the technical field of pressure dies, in particular to a heating processing device and a processing technology for manufacturing the pressure dies. The heating processing device comprises a workbench, an electromagnetic induction heater and a station, wherein the electromagnetic induction heater is arranged on the workbench, and the station is arranged on the workbench and is used for holding the pressure die to be heated; heat treatment is carried on the pressure die to be heated through the electromagnetic induction heater, and the inner diameter of an inner cavity of a die sleeve in the pressure die is larger than the outer diameter of a die core by virtue of heat expansion and contraction principle, so that the die core is inserted into the inner cavity of the die sleeve or the die sleeve and the die core in interference fit are separated from each other. According to the heating processing device and the processing technology for manufacturing the pressure dies, the structure is simple and compact, and the design is novel and reasonable; the electromagnetic induction heater is used for carrying out heating treatment on the die sleeve of the pressure die, so that high heating speed is achieved, smooth and continuous temperature distribution change of the inner wall of the die sleeve of the pressure die is ensured, thus achieving small temperature difference, uniform heating and easy control so as to be suitable for manufacturing large-batch pressure dies; in addition, the manufacturing can be completed by a single person, thus improving the production efficiency and quality of the pressure dies and having strong practicability and good application prospect.

Description

technical field [0001] The invention relates to the technical field of pressure molds, in particular to a heat treatment device and a treatment process for pressure mold manufacturing. Background technique [0002] In metal pressure processing, the metal is forced through the die under the action of external force, the cross-sectional area of ​​the metal is compressed, and the required cross-sectional shape and size are obtained. The die-casting die forging process is completed on a special die-casting die forging machine. The basic process is that the molten metal is cast and filled into the cavity of the mold at a low or high speed. The mold has a movable cavity surface, and it follows the cooling process of the molten metal Pressure forging, in the die casting industry, some products are produced in large batches, requiring continuous production of hundreds of thousands or even millions of products. The life of die-casting molds is generally only 70,000 to 80,000 modules...
