Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a novel stamping die. Background Technology
[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping molds). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. With rapid economic development and diversified market demands, people are increasingly demanding shorter product production cycles, especially in small-batch or even single-piece production. This requires modern manufacturing technology to not only have high flexibility but also newer production models that can better meet the rapidly changing market demands. CNC unit stamping die rapid prototyping technology was developed to adapt to this situation. A search revealed that in China, the authorization announcement number CN215467485U... The patent discloses a novel stamping die, including a base. A connecting bracket is fixedly connected to one end of the top outer wall of the base. A telescopic cylinder is fixedly installed on the top of the connecting bracket. A connecting seat is fixedly connected to the bottom end of the output shaft of the telescopic cylinder. A sleeve is fixedly connected to the bottom outer wall of the connecting seat. Two sets of vertical rods are fixedly connected to the top outer wall of the base at positions corresponding to the sleeve. A telescopic spring is sleeved on the outer wall of the vertical rod. This invention, by setting up telescopic springs, telescopic blocks, and positioning blocks, and by setting telescopic springs inside the mounting seat, facilitates the insertion of the connector into the connecting seat for positioning and fixed installation. Compared with the traditional method of replacing stamping heads, this novel stamping die simplifies the stamping head replacement process, reduces the manual labor intensity during replacement, and improves stamping efficiency.
[0003] However, in actual use, since the two sets of telescopic blocks are located on both sides of the connector, the two sets of short columns need to be separated and moved simultaneously. In addition, the gravity of the stamping head causes a large friction at the connection, which may require two hands to operate different short columns to make the telescopic blocks detach from the connector. At the same time, the stamping head also needs to be lifted when separating. Therefore, this solution requires multiple people to cooperate in changing the stamping head, and the process is quite complicated. Utility Model Content
[0004] To address the problem that existing stamping dies are inconvenient for a single person to change the stamping head, this utility model provides a new type of stamping die.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0006] A novel stamping die includes a base with columns mounted at the four corners of its top surface. A top plate is mounted on the top of each column. An upper die base is provided between the top plate and the base. Sliding holes for intersecting the columns are formed at the four corners of the upper die base. The upper die base includes a lifting plate. A seat body is mounted on the bottom surface of the lifting plate. A transverse cavity is formed inside the seat body. Telescopic plates are slidably connected to both sides of the transverse cavity. An inclined groove is formed on the top surface of each telescopic plate. A spring is connected to one end of each telescopic plate. One end of each spring is connected to the inner wall of the transverse cavity. A pair of longitudinal cavities are formed at the connection between the seat body and the lifting plate. A lower pressure rod is slidably connected inside the pair of longitudinal cavities. An inclined surface is provided at the bottom end of the lower pressure rod. The bottom surface of the inclined surface is flush with the inner wall of the inclined groove. A stamping head is inserted into the bottom surface of the seat body. A locking slot for engaging with the telescopic plates is formed on both sides of the stamping head.
[0007] Furthermore, a hydraulic cylinder is installed on the top surface of the top plate, and the output end of the hydraulic cylinder passes through the top plate and is connected to the top surface of the lifting plate.
[0008] The beneficial effect of adopting the above-mentioned further solution is that the lifting plate is driven by the output end of the hydraulic cylinder, so that the upper mold base can achieve stable lifting and lowering activities on the column.
[0009] Furthermore, the top surface of the base has a hollowed-out groove, and a lower mold base is placed inside the hollowed-out groove. The lower mold base includes a base plate, and a punch hole is formed at the center of the top surface of the base plate.
[0010] The beneficial effect of adopting the above-mentioned further solution is that the setting of the hollow groove provides space for the placement of the lower mold base, and the setting of the punch hole facilitates the removal of waste material.
[0011] Furthermore, recessed handles are provided on both sides of the outer wall of the seat plate.
[0012] The advantage of adopting the above-mentioned further solution is that the recessed handle makes it easier to lift the seat.
[0013] Furthermore, the stamping head includes a head body and a connecting pile, wherein the connecting pile is installed on the top surface of the head body and the connecting pile is located inside the base body.
[0014] The beneficial effect of adopting the above-mentioned further solution is that the installation and use of the connecting pile provides a structure for the docking of the punch head and the upper die base.
[0015] Furthermore, a pushing mechanism is slidably connected to the bottom of the base. The pushing mechanism includes a push plate, a crossbar is installed on the outer wall of the push plate, and a handrail is installed on the outer wall of the crossbar.
[0016] The advantage of adopting the above-mentioned further solution is that by holding the handle, it is more convenient for the crossbar to drive the push plate to move, thereby making it easier to clean the stamping waste accumulated at the bottom of the base.
[0017] Furthermore, a shovel plate is connected to the bottom of the outer wall of the push plate, and the bottom surface of the shovel plate is flush with the bottom surface of the push plate.
[0018] The beneficial effect of adopting the above-mentioned further solution is that, through the connection and use of the shovel plates, it can scoop up waste from the ground, thereby facilitating the improvement of the cleaning efficiency of the push plate.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] This novel stamping die, through the coordinated use of the column, top plate, upper die base, and stamping head, makes changing the stamping head more convenient, requiring only a single operator. Specifically, by causing the lifting plate to raise the seat body on the column, the top of the lower pressure rod in the seat body contacts the bottom surface of the top plate. By further raising the height of the upper die base, the top plate applies pressure to the lower pressure rod, causing it to slide vertically downwards. Combined with the positional relationship between the bottom surface of the inclined surface and the inclined groove, the telescopic plate can compress the spring during the pressing process of the lower pressure rod, and retract inside the transverse cavity until the telescopic plate separates from the latch in the stamping head, thus facilitating the function of changing the stamping head of this stamping die.

[0029] 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. Example
[0030] Please see Figures 1-5As an embodiment of this utility model, a hydraulic cylinder 400 is further installed on the top surface of the top plate 300. The output end of the hydraulic cylinder 400 passes through the top plate 300 and is connected to the top surface of the lifting plate 5001. The output end of the hydraulic cylinder 400 drives the lifting plate 5001 to move, so that the upper mold base 500 can achieve stable lifting and lowering on the column 200. A hollow groove is opened on the top surface of the base 100, and a lower mold base 600 is placed inside the hollow groove. The lower mold base 600 includes a base plate 6001. A punch 6002 is opened at the center of the top surface of the base plate 6001. Through the setting of the hollow groove This provides space for the placement of the lower die base 600. In conjunction with the setting of the punch 6002, it facilitates the removal of waste material. The outer walls of the base plate 6001 are respectively provided with recessed handles 6003. The setting of the recessed handles 6003 makes it easier to lift the base plate 6001. The punching head 800 includes a head body 8001 and a connecting pin 8002. The connecting pin 8002 is installed on the top surface of the head body 8001. The connecting pin 8002 is located inside the base body 5002. The installation and use of the connecting pin 8002 provides a structure for the docking of the punching head 800 and the upper die base 500. Example
[0031] Please see Figures 1-5 As an embodiment of this utility model, a pushing mechanism 700 is slidably connected to the bottom of the base 100. The pushing mechanism 700 includes a push plate 7001, a crossbar 7002 is installed on the outer wall of the push plate 7001, and a handrail 7003 is installed on the outer wall of the crossbar 7002. By holding the handrail 7003, it is more convenient for the crossbar 7002 to drive the push plate 7001 to move, thereby facilitating the cleaning of the stamping waste accumulated at the bottom of the base 100. A shovel plate 7004 is connected to the bottom end of the outer wall of the push plate 7001. The bottom surface of the shovel plate 7004 is flush with the bottom surface of the push plate 7001. Through the connection and use of the shovel plate 7004, it can shovel up the waste on the ground, thereby improving the cleaning efficiency of the push plate 7001.
[0032] Specifically, the working principle of this new type of stamping die is as follows: First, check the structure of the stamping die for integrity. After ensuring the structure is intact, place the workpiece for stamping. The hydraulic cylinder 400 is activated, causing its output end to move the lifting plate 5001. This allows the upper die holder 500 to move stably up and down on the column 200 until the top of the lower pressure rod 5004 in the seat 5002 contacts the bottom surface of the top plate 300. Further raising the height of the upper die holder 50 causes the top plate 300 to apply pressure to the lower pressure rod 5004, causing it to slide vertically downwards and cooperate with the inclined surface. The positional relationship between the bottom surface and the inclined groove allows the telescopic plate 5003 to compress the spring 5005 during the pressing process by the pressure rod 5004, and to retract inside the transverse cavity until the telescopic plate 5003 separates from the slot in the stamping head 800. This facilitates the function of changing the stamping head 800 of the stamping die. Furthermore, by holding the handle 7003, it is more convenient for the crossbar 7002 to drive the push plate 7001 to move, thus facilitating the cleaning of the stamping waste accumulated at the bottom of the base 100. At the same time, the use of the shovel plate 7004 improves the cleaning efficiency of the push plate 7001.
