Description

Technical Field

[0001] The utility model relates to a mold, in particular to a flanging and shaping mold for an automotive auxiliary engine blade. Background Art

[0002] The automotive auxiliary engine blade is an intermediate component connecting the steering column to the engine compartment, and is a key component for the stable connection of the automotive steering column. The automotive auxiliary engine blade includes a bottom plate, and the edge of the bottom plate is folded upwards; side plates are respectively arranged on both sides of the bottom plate, a connection hole is arranged on the side plate on one side of the bottom plate, and a connection groove is arranged on the side plate on the other side of the bottom plate; bolt holes are distributed in a "pin" shape on the bottom plate, and bolt assembly grooves are arranged on the bottom plate outside the bolt holes. Currently, the production process of the automotive auxiliary engine blade includes punching a substrate, connection holes, and bolt holes on a steel strip, punching bolt assembly grooves on the substrate, and flanging the substrate. The connection holes, bolt holes, and substrate are operated on a single plane, so they can be formed in one punching operation. However, the bolt assembly grooves are recessed downwards, and the substrate flanging is folded upwards, both of which are operated in the vertical direction. Therefore, punching the substrate, connection holes, and bolt holes cannot be carried out synchronously; at the same time, due to the opposite directions of the bolt assembly grooves (recessed downwards) and the side plate flanging (folded upwards), it is not easy to carry out in the same process. The current method is to separate punching the bolt assembly grooves on the substrate and flanging the substrate into two separate processes. When punching the bolt assembly grooves and flanging the substrate are carried out separately, not only the transfer between different machines will waste time, but also the process of multiple positioning will waste time, resulting in low production efficiency. Therefore, it is necessary to design a flanging and shaping mold for an automotive auxiliary engine blade to solve the above problems. Summary of the Invention

[0003] The purpose of the utility model is to provide a flanging and shaping mold for an automotive auxiliary engine blade that can punch bolt assembly grooves and flange the substrate simultaneously, greatly improving production efficiency, in view of the deficiencies of the prior art.

[0004] The technical solution of the utility model is as follows:

[0005] A flanging and shaping mold for an automotive auxiliary engine blade is composed of a male mold and a female mold, with the female mold arranged below the male mold; it is characterized in that: the female mold is composed of a mold base, a template, a module, and a stop oil cylinder. A template is arranged on the mold base, a mold hole is arranged at the center of the top of the template, a module is movably inserted into the mold hole, and a plurality of mold grooves are arranged on the top end face of the module in a "pin" shape; a stop oil cylinder is arranged on the mold base below the module, and the end of the piston rod of the stop oil cylinder is connected to the module; the male mold is composed of a connecting plate and a punch, a punch is arranged at the bottom of the connecting plate, and a plurality of convex molds are arranged on the bottom end face of the punch in a "pin" shape.

[0006] A positioning plate is arranged on the top of the template, a through hole with the same shape as the die hole and a greater horizontal and vertical width than the die hole is arranged on the positioning plate, and positioning grooves are arranged on both sides of the through hole.

[0007] The inner wall of the die hole is symmetrically provided with limit sliding grooves; limit blocks are respectively provided on both sides of the module, and the limit blocks are slidably connected with the limit sliding grooves.

[0008] A limit pin is installed on the punch through a return spring.

[0009] A plurality of demoulding cylinders are arranged on the connecting plate, and the piston rod ends of the demoulding cylinders are flush with the punch end faces between the convex dies.

[0010] The beneficial effects of the utility model are:

[0011] The flanging shaping die for the automobile auxiliary engine blade can punch the bolt assembly groove through the punch and the die groove, and can flanging the base plate and erect the side plate through the punch and the hole. The bolt assembly groove and the flanging of the base plate can be punched at the same time in one punching stroke, which can effectively reduce the process. Therefore, when punching the bolt assembly groove and flanging the base plate, there is no need to transfer between multiple machines and repeat positioning, which can effectively improve production efficiency. The problem of low production efficiency in the current production process of automobile auxiliary engine blades is solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The flanging and shaping die for the auxiliary engine blade of an automobile is composed of a male die and a female die. The female die is arranged below the male die. The male die is connected to the piston rod of a punching machine, and the female die is fixed on a base. The female die is composed of a die base 1, a template 2, a module 3, and a stopping oil cylinder 4. A template 2 is arranged on the die base 1. A die hole 5 is arranged at the center of the top of the template 2. When the male die presses downward to press a base plate into the die hole 5, under the action of the die hole 5, the part with a width greater than that of the die hole 5 is folded upward, so as to fold the edge and side plate of the base plate upward, and at the same time form the bottom plate. The module 3 is movably inserted into the die hole 5 to clamp and fix the base plate through the module 3 in cooperation with the male die, so as to prevent the base plate from shifting during the punching process, ensure accurate punching, and thus ensure the quality of the finished product. Multiple die grooves 6 are arranged in a "pin" shape on the top end face of the module 3. When the male die presses the base plate into the die groove 6, the base plate is deformed through the die groove 6 to form a bolt assembly groove on the base plate. A stopping oil cylinder 4 is arranged on the die base 1 below the module 3. The end of the piston rod of the stopping oil cylinder 4 is connected to the module 3. The function of the stopping oil cylinder 4 is, on the one hand, to support the module 3, so that when the male die presses the base plate downward, the punching force on the base plate is ensured through the support of the module 3, and the base plate can be deformed into the die groove 6; on the other hand, the module 3 is pushed upward by the stopping oil cylinder 4, and then the punched finished product is pushed away from the die hole 5 for demolding.

[0023] The male die is composed of a connecting plate 7 and a punch 8. The punch 8 is arranged at the bottom of the connecting plate 7 to press the base plate downward through the punch 8, so that the base plate is formed under the pressing of the punch 8; at the same time, the base plate is clamped and fixed through the cooperation of the punch 8 and the module 3 to avoid the shift of the base plate during the punching process and ensure the quality of the finished product. The connecting plate 7 can be connected to the piston rod of the punching machine, so that the punching machine can drive the punch 8 to move downward through the connecting plate 7 for punching. Multiple punching dies 9 are arranged in a "pin" shape on the bottom end face of the punch 8 to squeeze the base plate through the cooperation of the punching dies 9 and the die grooves 6, so that the base plate is deformed downward to form the bolt assembly groove by punching.

[0024] A positioning plate 10 is arranged on the top of the template 2. A through hole 11 which has the same shape as the die hole 5 and a transverse and longitudinal width greater than that of the die hole 5 is arranged on the positioning plate 10 to position the base plate through the through hole 11, so that the base plate is accurately placed on the die hole 5 to ensure accurate punching of the base plate. Positioning grooves 12 are respectively arranged on both sides of the through hole 11 to position the side plate through the positioning grooves 12, further position the base plate, and prevent the base plate from shifting.

[0025] The inner wall of the die hole 5 is symmetrically provided with a limited slot 13; the two sides of the module 3 are respectively provided with a limited block 14, and the limited block 14 is slidably connected with the limited slot 13. The function of the limited block 14 is to limit the upward spacing of the module 3 through the limited block 14 and the limited slot 13, so that the high point of the module 3 is flush with the template 2, and thus the module 3 is not easy to affect the positioning of the substrate; at the same time, the limited block 14 cooperates with the limited slot 13 to limit the position of the module 3, so that the module 3 will not rush out of the die hole 5 when the stop cylinder 4 supports the module 3.

[0026] A limit pin 16 is installed on the punch 9 via a return spring 15, so that after the limit pin 16 is inserted into the bolt hole on the substrate, the substrate can be further positioned by the limit pin 16 to prevent the substrate from shifting during the stamping process.

[0027] A plurality of demoulding cylinders 17 are arranged on the connecting plate 7, and the piston rod end of the demoulding cylinder 17 is flush with the end surface of the punch 8 between the punch 9. The function of the demoulding cylinder 17 is to push the stamped finished product downward through the demoulding cylinder 17, thereby pushing the finished product away from the punch 8, and then demoulding the finished product from the punch 8.

[0028] When the flanging shaping die of the automobile auxiliary engine blade is working, the substrate is placed in the through hole 11 and the positioning groove 12 on the positioning plate 10. After the substrate is placed in place, the punching machine is started, and the punching machine drives the punch 8 to punch downward through the connecting plate 7. During the downward movement of the punch 8, the limit pin 16 on the punch 9 is first inserted into the bolt hole. During the downward movement of the punch 8, the punch 9 squeezes the substrate, and the punch 9 cooperates with the die groove 6 to form the bolt assembly groove. When the bolt assembly groove is formed, the punch 8 cooperates with the module 3 to clamp and fix the substrate, and at the same time, all the pressure of the punch 8 is applied to the module 3. When the pressure of the punch 8 on the module 3 exceeds the thrust of the stop cylinder 4 on the module 3, the punch 8, the substrate, and the module 3 are synchronously moved downward. During the downward movement of the substrate, the punch 8 squeezes the substrate into the die hole 5, and the edge of the substrate and the side plate are folded upward under the action of the die hole 5. After folding in place, the punch 8 is reset upward. During the upward movement of the punch 8, the stop cylinder 4 pushes the finished product upward through the module 3 to demold the female mold. After the finished product is demoulded from the female mold, the demoulding cylinder 17 is started, and the finished product is pushed downward during the upward reset of the punch 8, thereby pushing the finished product and the punch 8 to be demoulded.

[0029] The flanging shaping die of the automobile auxiliary engine blade can punch the bolt assembly groove through the punch 9 in cooperation with the die groove 6, and can flanging the base plate and erect the side plate through the punch 8 in cooperation with the mold hole 5. The bolt assembly groove and the flanging of the base plate can be punched at the same time in one punching stroke, which can effectively reduce the process. Therefore, when punching the bolt assembly groove and flanging the base plate, there is no need to transfer between multiple machines and repeat positioning, which can effectively improve the production efficiency. The problem of low production efficiency in the current production process of automobile auxiliary engine blades is solved.
