Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a multi-channel stamping die. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts.

[0003] Chinese patent publication number CN217858378U discloses a multi-channel stamping die, whose structure includes a stamping die main body, a stamping groove is opened on the stamping die main body, an external power supply jack is provided on the stamping die main body, and the external power supply jack is electrically connected to the electric drive structure provided on the stamping die main body. It also includes a local heating structure, which is provided on the stamping die main body, and the base of the local heating structure is connected to the stamping die main body by welding. Carbon fiber fan blades are provided inside the local heating structure, and the connecting end of the carbon fiber fan blade is welded to the inner wall of the local heating structure. A water pipe joint is provided on the stamping die main body, and one end of the water pipe joint extends to the interior of the stamping die main body.

[0004] The above patent has certain disadvantages. One end of the water pipe connector extends into the interior of the stamping die body, which will change the internal shape of the stamping die. During stamping, the shape of the water pipe mouth may appear on the lower side of the part to be stamped, resulting in quality problems in the product. In addition, a large number of local heating structures and carbon fiber fan blades are used to heat the parts to be stamped, which does not save resources enough and is not practical enough.

The water pipe joint 5 is screwed on the stamping die body 1 through the cooperation of the external thread 8 and the internal thread 4 and connected to the input and output ends of the serpentine flow channel 3. The left ends of the two groups of annular baffles 7 are both against the right end of the stamping die body 1. The rear end of the stamping die body 1 is fixed with a fixed plate 10, and the electric blower 9 is fixedly mounted on the fixed plate 10. The upper side of the rear end of the stamping die body 1 is symmetrically fixed with two groups of support plates 11. A shunt pipe 12 is fixedly mounted on the two groups of support plates 11. A blowing pipe 13 is fixedly connected between the output end of the electric blower 9 and the shunt pipe 12. There are multiple groups of fixed connections equidistantly on the front side of the shunt pipe 12. Blowing nozzle 14; when in use, the water pipe joint 5 is connected to the external water pipe, and the clamp 6 can make the water pipe sleeve firmly connected. Cooling water is supplied to the serpentine flow channel 3 through the water pump to cool the parts after stamping. Before stamping, by starting the electric blower 9, the electric blower 9 blows hot air into the diverter pipe 12 through the blowing pipe 13, and then blows the hot air evenly to the surface of the part to be stamped by the blowing nozzle 14, so that the stamped parts are heated and the plasticity is improved, and then stamping is carried out. After the stamping is completed, cooling water is supplied by the external water pump, and the cooling water enters the serpentine flow channel 3 from the input end through the water pipe joint 5. After flowing inside the serpentine flow channel 3, it flows out through the retaining ring 6 at the output end. Under the action of heat conduction, the heat is absorbed by the water, so that the cooling water takes away the heat, thereby cooling the parts after stamping. Since the serpentine flow channel 3 is arranged inside the stamping die body 1, the structure of the stamping groove 2 on the stamping die body 1 is not affected, thereby effectively avoiding quality problems of the product. When heating the stamping parts, only one electric blower 9 is used. Through the diversion of the diversion pipe 12, the blowing nozzle 14 evenly blows the hot air onto the parts to be stamped, thereby saving the use of resources and improving practicality.

[0029] The utility model is a multi-channel stamping die, and its working principle is that when in use, the water pipe joint 5 is connected to the external water pipe, the clamping ring 6 can make the water pipe sleeve firmly connected, and the cooling water is supplied to the serpentine flow channel 3 through the water pump to cool the parts after stamping. Before stamping, the electric blower 9 is started, and the electric blower 9 blows the hot air into the diversion pipe 12 through the blowing pipe 13, and then the blowing nozzle 14 blows the hot air evenly to the surface of the parts to be stamped, so that the stamped parts are heated and the plasticity is improved, and then stamping is carried out. After the stamping is completed, cooling water is supplied through the external water pump to cool the parts. Water enters the serpentine flow channel 3 from the input end through the water pipe joint 5, flows inside the serpentine flow channel 3, and flows out through the clamping ring 6 at the output end. Under the action of heat conduction, the heat is absorbed by the water, so that the cooling water takes away the heat, thereby cooling the parts after stamping. Since the serpentine flow channel 3 is arranged inside the stamping die body 1, the structure of the stamping groove 2 on the stamping die body 1 is not affected. After the stamping is completed, the electric telescopic rod 16 is started to push the push plate 17 to slide to the right along the stamping groove 2, so that the push plate 17 pushes the stamped parts out.
