Description

Technical Field

[0001] This utility model specifically relates to the field of workpiece shaping technology, and more specifically to a device with a thermal shaping mold. Background Technology

[0002] Metal sheet hot forming equipment is a specialized device used to heat and shape metal sheets. By precisely controlling parameters such as temperature, pressure, and time, the metal sheet can obtain the desired shape and properties. Heat is applied to the material to bring it to a certain temperature, at which the plasticity of the material increases. Then, with the help of the external force of the hydraulic cylinder, the mold is pushed to close, and pressure is applied to the metal sheet in the mold, causing the material to deform according to the predetermined shape. Then, the metal sheet in the mold is cooled, and the material will retain the shape after cooling.

[0003] However, in practice, it has been noted that most hot forming molds currently have electric heating tubes embedded in the mold or laser heaters installed on one side of the mold. Generally, the metal sheet is heated first, and then extrusion and shaping are performed after it is fully heated. Therefore, it takes a long time, and the high temperature will also raise the surface temperature of the metal sheet, which can easily burn the workers and result in poor safety. Utility Model Content

By utilizing a rectangular array of heating air holes on the heating connector, the residence time of the hot airflow on the inner side can be increased, ensuring that the heat from the airflow is directly transferred to the inner side of the mold. This guarantees the heating efficiency of the metal sheet during extrusion. Furthermore, cooling gas can be introduced into the inner side of the heating connector to rapidly cool the workpiece, preventing burns and improving safety during use. This addresses the technical problems mentioned in the background section.

The hydraulic cylinder 2 is fixedly connected to the top plate, and the fixed columns pass through the movable pressure plate 3.

[0027] Furthermore, a symmetrically arranged hot forming mold is provided between the base plate and the movable pressure plate 3, and a mold mounting base 4 is fixedly connected to both the side of the base plate near the movable pressure plate 3 and the side of the movable pressure plate 3 near the base plate, and a heat insulation isolation plate 7 is also fixedly connected between the mold mounting base 4 and the hot forming mold.

[0028] Furthermore, the hot forming mold includes a lower forming mold 5 and an upper forming mold 8, wherein the lower forming mold 5 includes a heat-conducting mounting plate 51 fixedly connected to the mold mounting base 4, and a heating connection seat 6 is provided between the heat-conducting mounting plate 51 and the mold mounting base 4. The heating connector 6 has heating holes arranged in a rectangular array, and the multiple heating holes are interconnected.

[0029] By adopting the above technical solution, since the heating connection seat 6 has heating holes arranged in a rectangular array and the heating holes are interconnected, the metal sheet is heated by heat conduction through the lower forming mold 5 and the upper forming mold 8. In addition, cooling gas can be introduced between the heating holes to shape the finished workpiece 9 after forming, prevent the finished workpiece 9 from rebounding after forming, and improve the forming effect of the equipment.

[0030] More specifically, the heat-conducting mounting plate 51 is fixedly connected in a rectangular array with positioning slide rods 52 and bottom blocking columns 53 on its upper part, and a shaping template 54 is also fixedly connected on its upper part. The positioning slide rods 52 and bottom blocking columns 53 are located at the four corners of the shaping template 54.

[0031] Furthermore, the upper shaping mold 8 includes a heat-conducting movable seat 81 fixedly connected to the movable pressure plate 3, and a heating connecting seat 6 is also fixedly connected between the heat-conducting movable seat 81 and the movable pressure plate 3. The lower end of the heat-conducting movable seat 81 is fixedly connected to a shaping pressure plate 84 corresponding to the shaping template 54.

[0032] By adopting the above technical solution, when the metal sheet is placed, the workpiece positioning rod 86 at the end of the forming plate 84 positions the metal sheet, while the side baffles 85 on both sides of the forming plate 84 restrict the position of the metal sheet. The side baffles 85 on both sides cooperate with the forming plate 84 to shape both sides of the finished workpiece 9, thereby improving the shaping effect.

[0033] Furthermore, the shaping plate 84 is provided with symmetrical side baffles 85 on both the front and rear sides, and the side baffles 85 are fixedly connected to the bottom of the heat-conducting movable seat 81. The end of the shaping plate 84 is also fixedly connected with a workpiece positioning rod 86.

[0034] More specifically, the bottom of the heat-conducting movable seat 81 is also provided with a positioning groove 82 corresponding to the positioning slide rod 52, and the end of the positioning slide rod 52 away from the heat-conducting mounting plate 51 is inserted into the inner side of the positioning groove 82, and the positioning groove 82 and the positioning slide rod 52 are slidably engaged.

[0035] Furthermore, the bottom of the heat-conducting movable seat 81 is also fixedly connected to a top blocking post 83 corresponding to the bottom blocking post 53, and the end of the top blocking post 83 away from the heat-conducting movable seat 81 is in contact with the end of the bottom blocking post 53.

[0036] By adopting the above technical solution, the metal sheet is placed between the lower forming mold 5 and the upper forming mold 8. Then, the hydraulic cylinder 2 pushes the upper forming mold 8 toward the lower forming mold 5 through the movable pressure plate 3. The forming pressure plate 84 in the upper forming mold 8 and the forming template 54 in the lower forming mold 5 cooperate with each other to extrude and shape the metal sheet, and finally form the finished workpiece 9.

[0037] The finished workpiece 9 is placed on top of the shaping template 54, and the bottom of the shaping pressure plate 84 is inserted into the finished workpiece 9. The side baffles 85 are located at the front and rear ends of the finished workpiece 9, respectively.

[0038] The heating connector 6 is provided with an air inlet and an air outlet on both sides, and the air inlet and the air outlet are respectively connected to the heating air hole. The heating gas or cooling gas flows from the air inlet to the air outlet. During this process, the heat is transferred to the lower shaping mold 5 and the upper shaping mold 8 through the heating air hole.

[0039] The working principle of this utility model is as follows: First, the metal sheet is placed on the shaping template 54 in the lower shaping mold 5. Then, the hydraulic cylinder 2 pushes the upper shaping mold 8 towards the lower shaping mold 5 via the movable pressure plate 3. Simultaneously, heating gas enters through the holes on the side of the heating connecting seat 6, heating the lower shaping mold 5 through the rectangular array of heating air holes on the heating connecting seat 6. The hot gas is then transferred through the heat-conducting mounting plate 51 to heat the shaping template 54, thereby heating the metal sheet on the shaping template 54. The upper shaping mold 8 and the lower shaping mold 5 close. The heated metal sheet is then deformed into a specific shape by the extrusion between the shaping template 54 and the shaping pressure plate 84. The heating airflow is then stopped, and cooling airflow enters the heating connecting seat 6. The heating connecting seat 6 transfers the cooling airflow to the shaping pressure plate 84 through the heat-conducting movable seat 81, thereby cooling the finished workpiece 9 and preventing springback after mold opening. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
