[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] For example, see Figure 1-Figure 4 The present invention provides a technical solution: an automobile sheet metal stamping die, comprising a working box 1, a telescopic column 2 is slidably connected to the inner wall of the working box 1, an upper die seat 3 is fixedly connected to the top of the telescopic column 2, a punch 4 is fixedly connected to the bottom of the upper die seat 3, and a lower die seat 8 is fixedly connected to the bottom of the inner wall of the working box 1, and further comprising: The compression mechanism 5 includes a die 501 fixedly connected to the top of the lower die seat 8, a placement groove 502 is provided at the bottom of the inner wall of the die 501, a transmission mechanism 6 is provided on the inner wall of the placement groove 502, a sliding mechanism 7 is provided at the bottom of the inner wall of the die 501, contact membranes 503 are fixedly connected to both sides of the inner wall of the die 501, a compression ring 506 is fixedly connected to the inner wall of the contact membrane 503, and a plurality of compression rings 506 are fixed to the inner wall of the contact membrane 503. When the sheet metal material is placed into the interior of the die 501, the larger the volume of the sheet metal material, the larger the contact surface with the compression ring 506, which makes the amount of gas discharged from the compression ring 506 into the pad 507 more, and finally flows into the push column 604, driving the push column 604 to extend and retract outward for a longer distance, the bottom of the inner wall of the die 501 is fixedly connected to the pad 507, the top of the pad 507 is fixedly connected to the telescopic rod 504, and the top of the telescopic rod 504 is provided with a contact assembly 505.

[0022] The contact assembly 505 includes a contact ring 5051 rotatably connected to the top of the telescopic rod 504. A storage cavity is provided inside the contact ring 5051. After the coolant is discharged into the storage cavity through the internal passage of the absorption ring 5054, when one end of the compression tube 5052 is subjected to external pressure, pressure is generated inside the storage cavity, thereby discharging the coolant inside the contact ring 5051 outward from the inside of the spray cavity 5053. The bottom of the contact ring 5051 is fixedly connected to the spray cavity 5053, the bottom of the inner wall of the contact ring 5051 is fixedly connected to the compression tube 5052, and the end of the contact ring 5051 away from the telescopic rod 504 is fixedly connected to the absorption ring 5054.

[0023] The working method of the first embodiment is as follows: first, the sheet metal material is placed into the die 501, the bottom of the sheet metal material will come into contact with the surface of the contact film 503, and the sheet metal material will squeeze the inside of the compression ring 506, so that the compression ring 506 will expand and contract downward on the inner wall of the die 501, and the inside of the compression ring 506 will generate gas after being squeezed, which will be sprayed into the transfer ring 601 through the pad 507, and the gas will flow into the inside of the transfer block 602 through the internal passage of the transfer ring 601, and the gas flowing into the inside of the transfer block 602 will enter the push column 604, and the push column 604 will expand and contract outward after receiving the gas and push the drive plate 607, so that the drive plate 607 moves toward the contact plate 6081, and will squeeze the extrusion tube 6084 during the movement, and one end of the extrusion tube 6084 will drive the telescopic block 605 to slide on the surface of the sliding rod 603 after being squeezed. When the surface of the sheet metal material slides toward the surface of the sheet metal material, it will drive the contact plate 6081 to come into contact with the surface of the sheet metal material, and can clamp and fix sheet metal materials of different specifications, and can also absorb heat at the position where the sheet metal material is deformed due to heat. At this time, one end of the extrusion tube 6084 will drive the other end to exert pressure on the interior of the cooling tank 6083 due to the push of the driving plate 607, causing the coolant inside the cooling tank 6083 to flow into the contact plate 6081 through the pressing ring 6085. While clamping the surface of the sheet metal material through multiple contact plates 6081, different volumes of coolant can be injected according to different types of sheet metal materials, so that when the sheet metal material is subjected to stamping, the heat generated by stamping can be absorbed by the coolant inside through the absorption holes on the surface of the contact plate 6081, thereby preventing the sheet metal material from being overheated and deformed in a certain part due to the lack of cooling measures during stamping.

[0024] Example 2: Based on Example 1, continue to refer to Figure 5-Figure 6 The transmission mechanism 6 includes a transmission ring 601, one end of the transmission ring 601 is fixedly connected to both sides of the pad 507, the end of the transmission ring 601 away from the pad 507 is fixedly connected to a transmission block 602, the transmission block 602 is fixedly connected to the right side of the inner wall of the placement groove 502, the surface of the transmission block 602 is fixedly connected to a sliding rod 603, the surface of the sliding rod 603 is slidably connected to a telescopic block 605, the inner wall of the transmission block 602 is slidably connected to a pushing column 604, the end of the pushing column 604 away from the transmission block 602 is fixedly connected to a driving plate 607, a pressure rod 606 is arranged on the top of the telescopic block 605, and an adjustment component 608 is arranged on the top of the pressure rod 606.

[0025] The regulating assembly 608 includes a contact plate 6081, which is fixedly connected to the top of the pressure rod 606. The surface of the contact plate 6081 is provided with an absorption hole. When the absorption hole contacts the surface of the sheet metal material, the heat on the surface of the sheet metal material will be absorbed by the cooling liquid inside the contact plate 6081. The inner wall of the contact plate 6081 is slidably connected to a pressure pipe 6082. The top of the contact plate 6081 is fixedly connected to a cooling tank 6083. The bottom of the cooling tank 6083 extends downward into the interior of the contact plate 6081. When the pressure pipe 6082 is in contact with the surface of the sheet metal material, the cooling liquid inside the contact plate 6081 absorbs the heat from the surface of the sheet metal material. When 82 is expanded and contracted inwardly on the inner wall of the contact plate 6081 by external force, pressure is generated on the coolant in the cooling tank 6083, causing the coolant to gush out from the top connection port of the cooling tank 6083. A pressing ring 6085 is fixedly connected to the top of the cooling tank 6083, and the end of the pressing ring 6085 away from the cooling tank 6083 is fixedly connected to the top of the contact plate 6081. An extrusion tube 6084 is slidably connected to the inner wall of the cooling tank 6083, and the end of the extrusion tube 6084 away from the cooling tank 6083 is fixedly connected to the top of the driving plate 607.

[0026] Working method of the second embodiment: when the contact plate 6081 comes into contact with the surface of the sheet metal material, the pressure tube 6082 on the inner wall of the contact plate 6081 will be squeezed and extended into the inner wall of the contact plate 6081. When the coolant inside the cooling tank 6083 is subjected to the pressure brought by the pressure tube 6082, the coolant will be discharged into the contact ring 5051 through the absorption ring 5054. The telescopic device inside the telescopic rod 504 is remotely started to drive the telescopic rod 504 to extend and retract up and down. The contact ring 5051 is rotated inward to drive the contact ring 5051 to move to the surface of the feed chamber 7056 on the left side of the rotating frame 7051. The surface of the sheet metal material is used to squeeze one end of the compression tube 5052, so that the compression tube 5052 is expanded and contracted inwardly into the contact ring 5051. The pressure applied to the inside of the contact ring 5051 by the inward expansion and contraction of one end of the compression tube 5052 causes the coolant in the contact ring 5051 to be sprayed out through the spray cavity 5053. The coolant then passes through the feed cavity 7056 and enters the cladding plate 7052. The required coolant dosage can be determined according to sheet metal materials of different specifications, so as to avoid the heat generated on the surface of the sheet metal material due to stamping not being cooled well, which ultimately leads to deformation of the surface of the sheet metal material.

[0027] Example 3: Based on Example 1, continue to refer to Figure 7-Figure 8 The sliding mechanism 7 includes a telescopic frame 702, which is fixedly connected to the bottom of the inner wall of the die 501. The surface of the telescopic frame 702 is slidably connected to a sliding plate 701. The top of the sliding plate 701 is fixedly connected to a telescopic plate 703. The inner wall of the telescopic plate 703 is slidably connected to a movable frame 704. The surface of the movable frame 704 is provided with a cooling component 705.

[0028] The cooling assembly 705 includes a rotating frame 7051, the left side of the rotating frame 7051 is rotatably connected to the surface of the movable frame 704 through a rotating shaft, the inner wall of the rotating frame 7051 is rotatably connected to a covering plate 7052 on both sides through a rotating shaft, cooling grooves 7053 are provided on both sides of the covering plate 7052, a feeding chamber 7056 is provided on the left side of the rotating frame 7051, and an evaporator 7054 is fixedly connected to the top of the covering plate 7052.

[0029] The cooling assembly 705 also includes a propeller 7057, which is fixedly connected to the top of the cladding plate 7052. The end of the cladding plate 7052 away from the rotating frame 7051 is fixedly connected to the jet disk 7055. The inner wall of the propeller 7057 is slidably connected to a push rope 7058. The push rope 7058 has a telescopic reset characteristic. When pushed by the propeller 7057, it will telescope outward and push the push block 7059. The inner walls of the cooling groove 7053 are slidably connected to the push blocks 7059 on both sides through sliders. The end of the push rope 7058 away from the propeller 7057 is fixedly connected to the surface of the push block 7059.

[0030] The working method of the third embodiment is as follows: first, the covering plate 7052 is pulled toward the top, so that one end of the covering plate 7052 rotates on the inner wall of the rotating frame 7051 and tilts upward. After the sheet metal material is placed into the bottom of the inner wall of the concave mold 501 and is clamped and fixed, the upward tilted covering plate 7052 is pushed downward, so that the covering plate 7052 rotates toward the bottom and is flush with the rotating frame 7051. By starting the controller, the sliding plate 701 is driven to slide on the surface of the telescopic frame 702. When the material plate 701 drives the covering plate 7052 to move to the surface of the contact ring 5051, the spraying cavity 5053 is extended outward into the interior of the spraying cavity 5053. When the spraying cavity 5053 sprays the cooling liquid outward into the interior of the rotating frame 7051, the cooling liquid is absorbed into the pushing rope 7058 by the absorption capsule inside the pushing block 7059 through the interior of the rotating frame 7051. By starting the propeller 7057, the pushing rope 7058 is extended outward. 8 will push the push block 7059, and the push block 7059 moving outward will produce an extrusion contact with the inner wall of the cooling groove 7053, thereby pushing the push block 7059, and the interior of the push block 7059 will discharge the coolant inside the absorption capsule into the cooling groove 7053 due to the pressure. When the push block 7059 slides on the inner wall of the cooling groove 7053 toward the jet disk 7055, the coolant will flow inside the cooling groove 7053 due to the push of the push block 7059. When the sheet metal material is stamped, its top has high temperature heat. At this time, the covering plate 7052 contacts the top of the sheet metal material. The heat from the top of the sheet metal material can be absorbed into the interior through the cooling groove 7053. When the evaporator 7054 is remotely started, the heat value absorbed by the coolant is accelerated and converted into gas to be ejected from the inside of the jet disk 7055, which can accelerate the cooling of the overheated area on the top of the sheet metal material to ensure that the local position of the sheet metal material is not deformed due to overheating.
