Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a flip-type cold stamping die. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. Cold stamping is a processing method that uses dies on a press at room temperature to apply pressure to materials, causing them to separate or deform, thereby obtaining parts with certain shapes, sizes, and properties. Stamping dies are one of the important components in the forming of stamped workpieces.

[0003] For example, Chinese patent application number 202021882148.X discloses a flip-type automotive cold stamping die, belonging to the field of stamping die technology. It includes a base and a stamping seat. The top of the base is fixedly connected to a lower die, and the bottom of the stamping seat is fixedly connected to two connecting rods. The stamping seat is connected to a mounting seat through the connecting rods. The mounting seat has two limit holes inside. A fixing seat is fixedly connected between the mounting seats. By simply pulling the pin, the spring A is stretched, the bottom of the pin is lifted and pulled out to the outside of the mounting seat. The mounting seat and the fixing seat can be flipped along the connecting rod, thereby flipping the upper die. After reaching a suitable angle, the pin is released, and under the elastic force of the spring A, the pin moves down and resets, automatically inserting into the limit hole to complete the fixing of the upper die. Compared with traditional flip-type stamping dies, it improves the flipping efficiency and operation convenience of the upper die.

[0004] However, the stamping die still has some shortcomings in actual use. For example, after stamping, it is necessary to wait for the blanking to be completed before the next stamping can be carried out. The blanking process of the stamped product is cumbersome, the preparation stage takes too long, the stamping efficiency is low, and after multiple stampings, the temperature of the lower die itself will rise, so it is necessary to standby cooling, which affects the stamping operation. Summary of the Invention

[0005] The purpose of this invention is to provide a flip-type cold stamping die to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flip-type cold stamping die, including a lower die assembly, wherein an upper die assembly is fixedly installed on the top of the lower die assembly;

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: including a lower mold assembly 1, and an upper mold assembly 2 is fixedly installed on the top of the lower mold assembly 1;

[0023] The lower mold assembly 1 includes a concave base 101. A conveyor 102 is fixedly installed on the inner bottom surface of the concave base 101. A soft pad is laid on the outer surface of the conveyor 102. An installation plate 103 is fixedly installed on one edge of the middle part of the top surface of the concave base 101. A first servo motor 104 is fixedly installed on the top surface of the installation plate 103. A worm gear 105 is fixedly installed at the bottom end of the output shaft of the first servo motor 104. A rotating shaft 106 is rotatably installed on the top of the concave base 101. A worm wheel 107 is fixedly sleeved on one end of the shaft of the rotating shaft 106. A sleeve 108 is fixedly sleeved on the middle part of the shaft of the rotating shaft 106. Both sides are fixedly installed with lower molds 109. Support plates 110 are fixedly installed on the top of both sides of the front of the concave base 101. Horizontal plates 111 are fixedly installed on the top surface of the two support plates 110. A sliding groove is opened on the front of the horizontal plate 111. A double-headed screw 112 is rotatably installed in the sliding groove. Threaded sliders 113 are threadedly sleeved at both ends of the double-headed screw 112. A second servo motor 114 is fixedly installed on one side of the horizontal plate 111. One end of the output shaft of the second servo motor 114 is fixedly connected to one end of the double-headed screw 112. Slots are opened on the top of both sides of the concave base 101. Support pads 115 are slidably inserted into the slots.

[0024] In this embodiment, the upper mold assembly 2 includes a concave frame 201, a hydraulic cylinder 202 is fixedly installed in the middle of the top surface of the concave frame 201, and a stamping upper mold 203 is fixedly installed at the bottom end of the piston rod of the hydraulic cylinder 202.

[0025] Vertical shafts 204 are fixedly inserted into the two corners of one side of the horizontal portion of the concave frame 201. The plate body of the upper stamping die 203 is slidably sleeved on the shaft body of the two vertical shafts 204, making the upper stamping die 203 more stable during the pressing process.

[0026] The worm wheel 107 is located on one side of the worm 105 and is meshed with the worm 105. The rotation of the worm 105 can drive the worm wheel 107 to rotate. The rotation of the worm wheel 107 can drive the rotating shaft 106 and the sleeve 108 to rotate. The rotation of the sleeve 108 can drive the two lower dies 109 to rotate, thereby causing the lower dies located in the stamping area to flip to the rear, so that the idle lower dies 109 can be rotated to the stamping position.

[0027] The two ends of the double-headed screw 112 have opposite thread directions. The concave frame 201 is fixedly installed on the top surface of the concave base 101. The two support pads 115 correspond one-to-one with the two threaded sliders 113. The support pads 115 and the threaded sliders 113 are fixedly connected. After the two lower dies 109 are flipped over, the two support pads 115 are controlled to move closer to each other, which plays the role of supporting the lower die 109 located in the stamping position, making the structure of the stamping die more stable.

[0028] In use, the part to be stamped is taken out and placed in the mold groove of the lower mold 109 located below the upper stamping mold 203. Then, the hydraulic cylinder 202 is started. Under the action of the hydraulic cylinder 202, the upper stamping mold 203 is pressed down and the part to be stamped is stamped. After the stamping is completed, the second servo motor 114 is started. Under the action of the second servo motor 114, the double-headed screw 112 rotates. The rotation of the double-headed screw 112 can drive the two threaded sliders 113 to move closer or further away synchronously. Controlling the two threaded sliders 113 to move away from each other can drive the two support pads 115 to move away from each other, thereby allowing them to be pulled out from under the lower mold 109. Then, the first servo motor 104 is started. Under the action of the first servo motor 104, the worm gear 105 rotates. The rotation of the worm gear 105 can drive the worm wheel 10 The rotation of the worm gear 107 drives the rotating shaft 106 and the sleeve 108 to rotate. The rotation of the sleeve 108 drives the two lower dies 109 to rotate, thereby causing the lower dies located in the stamping area to flip to the rear, so that the idle lower dies 109 can rotate to the stamping position. During the process of the two lower dies 109 changing positions, the stamped parts will fall onto the conveyor 103 and then be transported away by the conveyor 102. There is no need for manual removal of the stamped parts from the lower dies 109, which simplifies the material feeding process. At the same time, materials can be directly fed into the lower dies 109 that have rotated to the stamping position, improving stamping efficiency. After the two lower dies 109 have been flipped, the two support pads 115 are controlled to move closer to each other, which plays a role in supporting the lower dies 109 located in the stamping position, making the structure of the stamping die more stable.

[0029] In summary, this flip-type cold stamping die allows the idle lower die 109 to be rotated to the stamping position. During the rotation of the two lower dies 109, the stamped part falls onto the conveyor 103 and is then transported away by the conveyor 102. This eliminates the need for manual removal of the stamped part from the lower die 109, simplifying the material feeding process. At the same time, it allows direct feeding into the lower die 109 that has been rotated to the stamping position, improving stamping efficiency. Furthermore, the alternating use of the two lower dies 109 avoids the situation where continuous stamping by a single lower die 109 leads to a temperature rise, thus affecting the service life.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
