[0002] The stamping device, also known as a stamping press, hydraulic press or oil press, is a large special equipment for pressing containers. It is mainly used to apply a force to materials through a mold installed on the press at normal temperature, causing them to separate or plastically deform, so as to obtain the required parts through a metal forming method. Stamping processing relies on the power of conventional or special stamping equipment to directly apply a deforming force to the sheet metal in the mold and cause deformation, thereby obtaining product parts with a certain shape, size and performance. During the production of household appliances, many hardware accessories with different external shapes and specifications need to be produced. Therefore, when forming the hardware accessories, they need to be stamped into the required specifications through stamping.

[0003] Currently, during the stamping process of hardware parts, the metal blank will deform due to stamping. During the deformation process, it is inevitable to generate metal chips and burrs due to friction with the mold. These chips and burrs remain in the stamping mold.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0019] Example 1: Please refer to Figures 1-4, The utility model: a stamping device for processing household appliance hardware accessories, including a base 1. A device frame 2 is fixedly connected to one side of the base 1. A stamping pump 3 is installed above the position near one side of the base 1 on the device frame 2. A stamping die 4 is provided at the top of the stamping pump 3. A switching groove 5 is opened at the top of the base 1. A stamping bottom die 6 is rotatably connected to the inner side near the opening of the switching groove 5. A flushing seat 7 is bolted to the bottom of the inner groove of the switching groove 5. A pressurized nozzle 8 is installed at the top of the flushing seat 7. Water suction pipes 13 are provided at both bottom positions on both sides of the flushing seat 7. A water suction pump is provided inside the flushing seat 7. The water suction pump is connected to the water suction pipes 13 and the pressurized nozzle 8 for sucking water into the pressurized nozzle 8 and spraying it for flushing and cleaning. Filter nets 9 are fixedly connected to both sides of the flushing seat 7 near the upper part of the water suction pipes 13. Cleaning openings 10 are penetrated through the side walls of the base 1 near the filter nets 9. A dryer 11 is fixedly connected to the inner groove wall of one side of the switching groove 5. An air jet opening 12 is installed on the outer wall of the dryer 11 near the inner groove of the switching groove 5. The high-temperature drying gas ejected by the dryer 11 can conveniently and quickly dry the stamping bottom die 6 after flushing, facilitating subsequent stamping processing.

[0020] A baffle 14 is rotatably connected to the opening position of the base 1 near the cleaning opening 10. A drain pipe 15 is fixedly connected to one side wall of the base 1. A shaft rod 16 penetrates and is fixedly connected to the stamping bottom die 6. The shaft rod 16 is rotatably connected to the inner groove wall of the switching groove 5. A motor 17 is bolted to the outer wall of the base 1 at one end opposite to the shaft rod 16. The output end of the motor 17 penetrates the side wall of the base 1 and is fixedly connected to the shaft rod 16. The motor 17 is an application of existing technology and will not be elaborated here.

[0021] The top of the flushing seat 7 is in a semi-cylindrical arc shape. The pressurized nozzles 8 are arranged in a fan shape on the top arc surface of the flushing seat 7. The filter nets 9 are inclined. The side of the filter nets 9 close to the flushing seat 7 is the inclined high point, and the side close to the cleaning opening 10 is the inclined low point. The inclined setting of the filter nets 9 can facilitate the subsequent handling of metal debris more conveniently and efficiently.

[0022] Example 2: Refer to Figure 1 - Figure 3 , on the basis of Example 1, further improvement is made:

[0023] Limit blocks 18 are fixedly connected to the outer walls on the opposite sides of the stamping bottom die 6. A cylinder 20 is bolted to the top of the base 1. A plug post 21 is fixedly connected to the output end of the cylinder 20 opposite to the limit blocks 18. A slot 19 is opened on one side of the limit block 18 opposite to the plug post 21. The plug post 21 is adaptively inserted into the slot 19 of the limit block 18. In order to ensure that the stamping bottom die 6 can stably perform stamping processing when the stamping bottom die 6 rotates and turns over, after the stamping bottom die 6 rotates and turns over, at this time, the cylinder 20 pushes the plug post 21 to insert into the slot 19 of the limit block 18, thereby limiting the stamping bottom die 6 and ensuring that the stamping bottom die 6 is more stable during stamping processing.

[0024] The working principle of the present utility model is as follows: during use, the metal blank to be processed is placed into the mold groove of the stamping bottom die 6. Subsequently, the stamping pump 3 is started to drive the stamping die 4 to perform stamping on the metal blank. After forming, the hardware part is taken out from the stamping bottom die 6. Then, the motor 17 is started to drive the shaft rod 16 to rotate. The shaft rod 16 drives the stamping bottom die 6 to rotate inside the switching groove 5 to turn the stamping bottom die 6 over. After turning over, the mold groove that has just been stamped on the stamping bottom die 6 faces downward, and the empty mold groove above can continue to be processed. At this time, the pressurized nozzle 8 at the top of the flushing seat 7 is started to spray high-pressure water to flush the stamping bottom die 6. During the flushing process, the water and metal debris fall, and the metal debris is blocked and filtered by the filter screen 9, and the water flows to the bottom of the base 1 and is then suction-transported by the suction pipe 13 to the pressurized nozzle 8 for spraying. After the cleaning of the stamping bottom die 6 is completed, the stamping process above the stamping bottom die 6 is completed. At this time, the above-mentioned rotation of the stamping bottom die 6 to turn it over is repeated, and the side of the stamping bottom die 6 that has just been flushed rotates past the dryer 11, and high-temperature gas is sprayed out through the air jet 12, so that the stamping bottom die 6 can be dried, which is convenient for continuing the stamping process. The process is continuous and efficient, reducing the impact of metal debris on subsequent production and processing, and ensuring the stamping quality of the hardware parts.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
