Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal shell forming, specifically a sheet metal shell cooling and forming device. Background Technology

[0002] Sheet metal processing is a key skill that sheet metal technicians need to master, and it is also an important process in the forming of sheet metal products. Sheet metal processing includes traditional methods and process parameters such as cutting, blanking, bending and forming. Sheet metal processing uses sheet metal to make boxes, shells, iron buckets, ventilation ducts, etc.

[0003] To ensure good heat dissipation, most devices use sheet metal casings. During the processing of these casings, bending equipment is used to bend the sheet metal parts and then assemble them. However, during the bending process, the stamping head is constantly in a state of stamping friction with the sheet metal parts. Under prolonged operation, this can cause the lower pressure block to overheat, reducing its lifespan. The overheated sheet metal is also prone to springback deformation, making it very inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies where the stamping head is constantly in a state of stamping friction with the sheet metal part, which leads to excessively high temperatures in the lower pressing block during prolonged operation, resulting in reduced lifespan of the lower pressing block and increased risk of springback deformation in the hot sheet metal, making it extremely inconvenient to use, this utility model provides a sheet metal shell cooling and forming device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a sheet metal shell cooling and forming device, including a stamping machine and a mounting base. A stamping cylinder is installed between the top of the mounting base and the stamping machine. A vertically downward stamping plate is provided at the bottom of the mounting base. The front end of the stamping plate is provided with an inclined stamping head for stamping and bending sheet metal parts. The stamping plate is provided with a cooling mechanism for cooling the stamping head. The cooling mechanism includes a positioning member provided on the side wall of the stamping plate. A horizontally arranged cold air duct is provided on the positioning member. An air outlet is provided on the cold air duct and inclined towards the stamping head. The stamping machine is also provided with a cooler for providing cold air to the cold air duct.

[0007] As a preferred technical solution of this utility model, the bottom of the mounting base is provided with a vertically downward mounting block, and the upper part of the stamping plate is provided with an embedding groove for the mounting block to be embedded, and the mounting block is provided with a through hole, the stamping plate is provided with positioning holes corresponding to the through holes, and a horizontally inserted positioning bolt is installed between the through hole and the positioning hole.

[0008] As a preferred embodiment of this utility model, the stamping plate is formed by joining several stamping sub-plates end to end.

[0009] As a preferred technical solution of this utility model, the two ends of the stamping subplate are respectively provided with protrusions and grooves, and the protrusions and grooves between adjacent stamping subplates are connected.

[0010] As a preferred embodiment of this utility model, the stamping subplate is made of high-strength metal material.

[0011] The beneficial effects of this utility model are:

[0012] 1. In this type of sheet metal shell cooling and forming device, the stamping plate is equipped with a cooling mechanism for cooling the stamping head. The cooling mechanism provides low-temperature cold air to the cold air duct through a cold air fan and then blows it onto the stamping head from the air outlet to cool the stamping head. This prevents the lower pressing block from overheating during long-term operation, which would reduce the service life of the lower pressing block and make the sheet metal plate prone to springback deformation due to high temperature. The use of air cooling will not adversely affect the performance and operation of the stamping head.

[0013] 2. In this sheet metal housing cooling and forming device, the stamping plate is formed by joining several stamping sub-plates end-to-end, adopting a split design. This allows for replacement of only the corresponding stamping sub-plate in case of localized damage, effectively reducing operating costs. Each stamping sub-plate has a protrusion and a groove at both ends, with the protrusions and grooves of adjacent stamping sub-plates engaging to facilitate connection and prevent misalignment.

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: Figure 1-4 As shown, this utility model discloses a sheet metal shell cooling and forming device, including a stamping machine 9 and a mounting base 1. A stamping cylinder 2 is installed between the top of the mounting base 1 and the stamping machine 9. A vertically downward stamping plate 3 is provided at the bottom of the mounting base 1. The front end of the stamping plate 3 is provided with an inclined stamping head 4 for stamping and bending sheet metal parts. A cooling mechanism 5 is provided on the stamping plate 3 to cool the stamping head 4. The cooling mechanism 5 includes a positioning member 6 provided on the side wall of the stamping plate 3. A horizontally arranged cold air pipe 7 is provided on the positioning member 6. An air outlet 8 inclined towards the stamping head 4 is provided on the cold air pipe 7. The stamping machine 9 is also provided with a cooler 18 for providing cold air to the cold air pipe 7. In this invention, the stamping plate 3 is provided with a cooling mechanism 5 for cooling the stamping head 4. The cooling mechanism 5 provides cool air at a lower temperature to the air duct 7 through the air cooler 18 and then blows it onto the stamping head 4 from the air outlet 8 to cool the stamping head 4. This prevents the lower pressing block from overheating during long-term operation, which would reduce the service life of the lower pressing block and make the sheet metal plate prone to springback deformation. The use of air cooling will not adversely affect the performance and operation of the stamping head 4.

[0022] The mounting base 1 has a vertically downward mounting block 10 at its bottom, and the upper part of the stamping plate 3 has an embedding groove 11 for the mounting block 10 to be embedded in. The mounting block has a through hole 12, and the stamping plate 3 has a positioning hole 13 that corresponds one-to-one with the through hole 12. A horizontally inserted positioning bolt 14 is installed between the through hole 12 and the positioning hole 13 to facilitate disassembly and assembly.

[0023] The stamping plate 3 is formed by joining several stamping sub-plates 15 end to end, adopting a split design. This way, when a part is damaged, only the corresponding stamping sub-plate 15 needs to be replaced, effectively reducing the cost of use. Each stamping sub-plate 15 has a protrusion 16 and a groove 17 at both ends. The protrusions 16 and grooves 17 of adjacent stamping sub-plates 15 align, facilitating the connection of the stamping sub-plates 15 without causing misalignment.

[0024] The stamping subplate 15 is made of high-strength metal material and is wear-resistant.

[0025] During operation, this sheet metal shell cooling and forming device uses a cooling mechanism 5 on the stamping plate 3 to cool the stamping head 4. The cooling mechanism 5 uses a cool air blower 18 to supply cool air to the cool air pipe 7 and then blows it from the air outlet 8 to the stamping head 4 to cool it down. This prevents the lower pressing block from overheating during long-term operation, which would reduce the service life of the lower pressing block and make the sheet metal plate prone to springback deformation. The use of air cooling will not adversely affect the performance and operation of the stamping head 4.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
