Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for automobile panels. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping dies are widely used in the automotive industry to perform stamping processing on automotive panel parts.

[0003] There is a Chinese patent with authorization announcement number CN217701007U, which discloses a stamping die for automobile panels, including: a lower plate and an upper plate; wherein, a first groove is provided on the upper surface of the lower plate, and a lower die for automobile panel stamping is installed in the first groove with clearance, and a second groove is provided on the lower surface of the upper plate, and an upper die for automobile panel stamping is installed in the second groove with clearance; four elastic connection components distributed in a rectangular array are arranged between the lower plate and the upper plate; multiple positioning holes are provided on both sides of the upper die, and two guide grooves symmetrical about the center position of the upper plate are provided in the longitudinal direction of the upper plate, and an elastic positioning plug-in is provided in the guide groove, and the elastic positioning plug-in is connected with the positioning hole with clearance; the elastic positioning plug-in is connected with the driving component arranged at the front end of the upper plate. The benefit of this application is that the upper die and the lower die are easy to disassemble and install, so that it is easy to replace them with different upper die and lower die structures, so as to meet more processing requirements.

[0004] Although the technical solution in the above patent document realizes the convenient disassembly and assembly of the upper and lower molds, the assembly structure adopted when disassembling and assembling the upper mold relies on the setting of the spring to achieve the locking limit of the upper mold during the actual operation, and the elastic positioning plug-in is relaxed by the adjustment of the driving component located at the front end of the upper plate to cancel the limit on the upper mold. Among them, the multiple springs distributed on the elastic positioning plug-in have a strong elastic effect, and the elastic positioning plug-in has a long limiting distance for the upper mold. Therefore, the driving component arranged at the end position only relies on the setting of the cam to achieve stable limit cancellation of the elastic positioning plug-ins on both sides. Therefore, there is a problem that part of the structure of the elastic positioning plug-in is still inserted in the upper mold after the operation, which affects its disassembly operation.

DETAILED DESCRIPTION

[0022] See also Figures 1 to 3In an embodiment of the utility model, a stamping die for automobile panel parts includes a lower plate 1 and an upper plate 2, wherein the upper plate 2 is located directly above the lower plate 1. The lower plate 1 and the upper plate 2 are movably connected via an elastic connection component 3. Through holes are provided at the four corners of the lower plate 1, so that it is convenient to assemble it on the workbench through fixing bolts, and a driving pressing device providing driving force is provided on the top of the upper plate 2.

[0023] The center of the top of the lower plate 1 is connected with the lower die 4 by bolts. A positioning mechanism 6 is provided at the bottom of the upper plate 2, and an upper die 5 matching the lower die 4 is installed on the positioning mechanism 6, wherein the upper die 5 is located directly above the lower die 4. A positioning groove for assembling the lower die 4 is provided at the center of the top of the lower plate 1.

[0024] The elastic connection components 3 include four components, which are distributed in a matrix on the lower plate 1. The elastic connection components 3 include a guide rod fixedly connected to the top outer wall of the lower plate 1, the top of the guide rod passes through the upper plate 2 and is fixedly connected to a stopper. A spring for shock absorption is sleeved on the guide rod, the top of the spring is fixedly connected to the upper plate 2, and the bottom of the spring is arranged on the lower plate 1.

[0025] The arrangement of the four elastic connection components 3 enables the upper plate 2 to not only drive the mold closing when driving the upper mold 5 to move downward to close the mold with the lower mold 4, but also to provide shock-absorbing and buffering protection for the clamping force of the upper mold 5.

[0026] The positioning mechanism 6 includes a carrier 61 fixedly connected to the bottom center of the upper plate 2 by bolts. A receiving groove is provided on the top shell wall of the carrier 61, and a bidirectional screw rod 62 is rotatably connected in the receiving groove. A plug-in assembly for plugging in the limiting upper mold 5 is movably connected on both sides of the bidirectional screw rod 62, and the plug-in assembly and the bidirectional screw rod 62 are connected by a folding piece 64. A positioning groove for assembling the upper mold 5 is also provided at the bottom center of the carrier 61, and a plurality of through holes are linearly provided on the shell walls on both sides of the positioning groove.

[0027] A plurality of support plates are sleeved on the bidirectional screw rod 62, the bottom of the support plates is fixedly connected to the bottom inner wall of the receiving groove, and a plurality of holes are linearly opened on the shell walls on both sides of the receiving groove. The plug-in assembly is composed of a main stopper 63 and a secondary stopper 65. Among them, the main stopper 63 includes a connecting plate 631 located on the side of the bidirectional screw rod 62, and a plurality of push rods 632 are linearly arranged on the side of the connecting plate 631 away from the bidirectional screw rod 62. The ends of the plurality of push rods 632 away from the connecting plate 631 respectively pass through the holes set on the side wall of the receiving groove, and are commonly connected to an integration plate 633.

[0028] A plurality of plug rods 634 for plugging the upper mold 5 are linearly distributed on the inner wall of the integration plate 633. The ends of the plurality of plug rods 634 away from the integration plate 633 are respectively plugged into the corresponding through holes opened on the shell walls on both sides of the positioning groove, and the upper mold 5 is clamped by the plug rods 634 to form a main limit lock on it.

[0029] The secondary limiting member 65 includes a side frame 651 fixedly connected to the outer wall of the integration plate 633 by bolts. A plurality of limiting rods 652 for inserting the upper mold 5 are linearly distributed on the inner wall of the side frame 651. The limiting rods 652 limit the insertion of the upper mold 5, thereby realizing secondary limiting locking thereof, and ensuring the stability of the limiting of the upper mold 5.

[0030] A plurality of inner groove rings are sleeved on the bidirectional screw rod 62. The folding member 64 is staggered by two struts. Both ends of each strut are connected to a support through a pin shaft. The end of the support close to the inner groove ring is fixedly connected to the outer shell wall, and the side of the support close to the connecting plate 631 is slidably connected to the side wall. A sliding groove is provided on the side of the connecting plate 631 close to the bidirectional screw rod 62. The support and the sliding groove are slidably connected, and the inner groove ring and the bottom inner wall of the accommodating groove are also slidably connected to ensure that the inner groove ring is linearly displaced despite the rotation of the bidirectional screw rod 62. The linear displacement of the inner groove ring, with the cooperation of the folding member 64, realizes the operation of locking or canceling the limit of the upper mold 5 by the plug-in components on both sides.

[0031] The working principle of the utility model is: when the mold body composed of the upper mold 5 and the lower mold 4 needs to be replaced, the upper plate 2 is moved downward under the action of the driving pressing device, and then the upper mold 5 and the lower mold 4 are stably closed under the action of the elastic connection component 3.

[0032] After the mold body is closed, the bolts on the lower mold 4 are first removed to cancel the assembly between it and the lower plate 1, and then the positioning mechanism 6 for assembling the upper mold 5 is adjusted to realize the disassembly of the upper mold 5. After the upper mold 5 is disassembled, it is combined with the lower mold 4 under the action of gravity to form the mold body, and then the upper plate 2 is moved up to facilitate the disassembly and removal of the mold body. After the old mold body is removed, the new mold body is placed on the lower plate 1 in the closed state, and the assembly between the lower mold 4 and the lower plate 1 is realized by bolt fixing.

[0033] When the new lower mold 4 is assembled, the upper plate 2 is moved downward so that the positioning mechanism 6 on it contacts the upper mold 5, and then the positioning mechanism 6 is adjusted to achieve the clamping limit of the upper mold 5 to complete the convenient replacement of the mold body.

[0034] During the adjustment operation, the positioning mechanism 6 rotates any end of the bidirectional screw 62 to make it rotate. During the rotation of the bidirectional screw 62, the multiple inner rings on it move, so as to adjust the folding members 64 at both sides and make them move, and then during the movement of the folding members 64, the displacement of the plug-in components at both sides is adjusted, so as to achieve the plug-in limit or cancel the limit operation of the upper mold 5.
