Description

[Technical field]

[0001] The invention relates to the technical field of light metal stamping and forging, in particular to a method and a product thereof for heating a metal warm stamping die using MHCM. [Background technology]

[0002] The application of high-strength light metals (such as aluminum alloys and magnesium alloys) in notebook computers has gradually shifted from mainstream machining to a combination of precision stamping and finishing. However, the ductility of high-strength light metals is poor at low temperatures, and stamping and forging cannot meet current manufacturing requirements. Therefore, the light metal can be heated first to increase its ductility, and then stamping and forging can be used to achieve a better appearance.

[0003] Currently, there are methods of heating the mold using a heating rod with multiple heating units or electromagnetic induction. However, this can cause uneven temperatures due to the heating component itself or installation problems. At the same time, the problem of uneven thermal field distribution of non-profile heating tubes is even more serious. In addition, high-power heating components and controllers are easily damaged, resulting in unplanned mold repairs.

[0004] In view of this, it is necessary to provide a method and product using MHCM as a metal warm stamping die heating method to solve the above problems. [Summary of the invention]

[0005] The technical problem to be solved by the present invention is: when manufacturing by stamping and forging, the light metal needs to be heated first to improve its ductility before stamping and forging. At present, there are heating rods with multiple heating units or electromagnetic induction methods to heat the mold, but it will cause uneven temperature due to the heating component itself or installation problems. At the same time, the problem of uneven thermal field distribution of non-profile heating tubes is more serious. In addition, high-power heating components and controllers are easily damaged, resulting in unplanned mold repair. Therefore, the present invention provides a method and product using MHCM as a metal warm stamping mold heating to solve the above problems.

[0006] The solution of the present invention to solve the technical problem is: a method for heating a metal warm punching die using MHCM, which comprises the following steps:

[0007] S1: Design the mold: Set the corresponding MHCM pipeline in the mold core according to the specifications of the metal material;

[0008] S2: Debug the mold: preheat the warm stamping mold to the required operating temperature using MHCM (multi-media rapid heating and cooling system);

[0009] S3: Placing materials: placing the pre-stamped and forged metal materials in the mold core of the mold;

[0010] S4: Heating material: The metal material placed in the mold core is heated to the required temperature according to the temperature of the mold;

[0011] S5: Stamping and forging: The impact force of the die causes the die to plastically deform the metal material. The force and speed of the stamping need to be adjusted according to the properties of the metal material and the requirements of the product.

[0012] S6: Take out the material: The metal material can be taken out after it is formed.

[0013] Preferably, the MHCM pipeline is connected to the MHCM host, and the oil temperature of the MHCM host is set according to the temperature shock requirement.

[0014] Preferably, the operating temperature of the mold is adjusted according to the melting point of the metal material and the pressed shape of the product, and the operating temperature usually does not exceed 260 degrees Celsius.

[0015] Preferably, in the heating mold, a thermocouple or other real-time temperature measuring equipment is used to monitor the mold temperature. The monitoring method can be manual or by installing a temperature monitoring device inside the mold. The purpose of monitoring is to adjust the abnormal mold temperature in time to prevent the quality of the warm-punched product from being affected by temperature fluctuations.

[0016] In addition, the present invention also provides a product using MHCM as a metal warm punching die for heating, which is a product formed by the above-mentioned die heating method.

[0017] The beneficial effect of the present invention is that the present invention designs an MHCM pipeline corresponding to the product in the mold core of the mold, so that the mold is heated using the MHCM (multi-media rapid heating and cooling system). After the mold temperature is increased to the warm stamping temperature, the metal material can be heated first to improve its ductility before stamping and forging. The MHCM has better temperature uniformity when heating the mold. At the same time, the MHCM has a cooling cycle and can adjust the mold temperature more quickly. Therefore, the use of a profiling pipeline for MHCM heating molds can solve the problems of uneven mold temperature and easy damage of the heating component, and improve the function of quickly adjusting the mold temperature.
