Description

Technical Field

[0001] This utility model relates to the field of punching technology, and in particular to a punching die. Background Technology

[0002] The workpiece includes a main body and a flange. The flange is located on the periphery of the main body. When processing the workpiece, it is necessary not only to punch the main body, but also to shape the flange.

[0003] In related technologies, when a punching die is in operation, the operator places the main body onto the positioning structure of the lower die before punching the main body. However, in order to facilitate the placement and removal of the workpiece on the positioning structure, there is often a certain gap between the positioning structure and the workpiece. This allows the workpiece to float relative to the positioning structure. Under these circumstances, it is difficult for the forming part on the upper die to accurately align with the flange of the workpiece. As a result, the punching of the main body and the forming of the flange often need to be processed separately using two sets of dies, which reduces the processing efficiency of the workpiece. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a punching die that can simultaneously complete the punching of the main body of a workpiece and the shaping of the workpiece flange.

[0005] A punching die according to an embodiment of the present invention is used to punch a workpiece. The workpiece includes a main body and a flange. The flange is disposed on the periphery of the main body. The punching die includes an upper die and a lower die. The lower die includes a lower die base, a first positioning member, a movable member, and a punching structure. The lower die base is provided with a shaping surface. The movable member includes a positioning part and a driving part distributed along a first horizontal direction. The positioning part and the first positioning member are distributed along a second horizontal direction. The positioning part and the first positioning member allow the main body to be fitted simultaneously. The movable member is movably disposed along the first horizontal direction. The punching structure is disposed on the side of the positioning part away from the driving part. The movable member is connected to the lower die base through an elastic connector. The elastic connector is used to provide elastic force to keep the movable member away from the punching structure along the first horizontal direction, so that the movable member cooperates with the first positioning member to position the flange on the shaping surface. The upper die has a first driving member and a shaping member. When the upper die approaches the lower die under the action of an external force, the first driving member can push the positioning part closer to the punching structure through the driving part to cooperate with the punching structure to complete the punching of the main body. The shaping member can cooperate with the shaping surface to shape the flange.

[0006] A punching die according to an embodiment of the present utility model has at least the following technical effects: In the use of the punching die of this application, the main body of the workpiece is fitted onto the positioning part and the first positioning member of the lower die, and the flange extends to the shaping surface area of ​​the lower die base. The movable part is connected to the lower die base through an elastic connector. Under normal conditions, the elastic force provided by the elastic connector can drive the movable part away from the punching structure in the first horizontal direction. When the movable part moves away from the punching structure in the first horizontal direction, the movable part drives the main body to move to abut against the horizontal side wall of the first positioning member, thereby realizing the positioning of the workpiece in the first horizontal direction. At this time, the flange of the workpiece is positioned on the shaping surface of the lower die base. When the upper die presses down to approach the lower die, its first driving member contacts the driving part of the movable part, pushing the movable part to approach the punching structure in the first horizontal direction, so that the positioning part of the movable part can cooperate with the punching structure to complete the punching of the horizontal side wall of the workpiece. At the same time, the shaping member of the upper die cooperates with the shaping surface of the lower die base to shape the flange of the workpiece. As can be seen from the above usage process, under the action of the elastic connector, after the main body of the workpiece is sleeved on the positioning part and the first positioning part, the positioning part can cooperate with the first positioning part to position the workpiece in the first horizontal direction. Subsequently, through the driving linkage between the movable part and the upper die, when the movable part cooperates with the first positioning part to position the workpiece for flanging, the movable part can cooperate with the punching structure to punch, so as to realize the simultaneous flanging and shaping and the punching of the main body, avoiding step-by-step processing and significantly improving efficiency.

Along the second horizontal direction, the second positioning member is disposed on the side of the positioning part away from the first positioning member.

A clearance hole is provided on the positioning part corresponding to the punching cutter. The upper die has a second driving member. The second driving member can push the second abutting inclined surface when the upper die approaches the lower die, so that the transmission member drives the punching cutter to approach the positioning part and cooperates with the clearance hole to complete the punching of the main body.

[0010] According to some embodiments of the present invention, a punching die includes a punching structure that further includes an abutment block. The abutment block is connected to one end of the transmission member near the positioning part through an elastic buffer member. The abutment block is used to cooperate with the positioning part to clamp the horizontal side wall of the workpiece.

[0011] According to some embodiments of the present invention, a punching die has an abutment block with an insertion through hole that allows the punching tool to pass through.

[0012] According to some embodiments of the present invention, a punching die includes a clearance hole comprising a first section and a second section.

[0023] The following is for reference. Figures 1 to 6 A punching die according to the first aspect of this utility model will be described in detail.

[0024] refer to Figures 1 to 6According to an embodiment of the present invention, a punching die is used to punch a workpiece 300. The workpiece 300 includes a main body 310 and a flange 320. The flange 320 is disposed on the periphery of the main body 310. The punching die includes an upper die 200 and a lower die 100. The lower die 100 includes a lower die base 110, a first positioning member 120, a movable member 130, and a punching structure 140. The lower die base 110 is provided with a shaping surface 110a. The movable member 130 includes a positioning part 131 and a driving part 132 distributed along a first horizontal direction. The positioning part 131 and the first positioning member 120 are distributed along a second horizontal direction. The positioning part 131 and the first positioning member 120 allow the main body 310 to be simultaneously fitted. The movable member 130 is movably disposed along the first horizontal direction. The punching structure... 140 is located on the side of the positioning part 131 away from the driving part 132. The movable part 130 is connected to the lower die base 110 through an elastic connector. The elastic connector is used to provide elastic force to keep the movable part 130 away from the punching structure 140 in the first horizontal direction, so that the movable part 130 cooperates with the first positioning part 120 to position the flange 320 on the shaping surface 110a. The upper die 200 has a first driving part 210 and a shaping part 220. When the upper die 200 approaches the lower die 100 under the action of external force, the first driving part 210 can push the positioning part 131 closer to the punching structure 140 through the driving part 132, so as to cooperate with the punching structure 140 to complete the punching of the main body 310. The shaping part 220 can cooperate with the shaping surface 110a to shape the flange 320.

[0025] In the use of the punching die of this application, the main body 310 of the workpiece 300 is sleeved on the positioning part 131 and the first positioning member 120 of the lower die 100. The flange 320 extends to the shaping surface 110a area of ​​the lower die base 110. The movable member 130 is connected to the lower die base 110 through an elastic connector. Under normal conditions, the elastic force provided by the elastic connector can drive the movable member 130 away from the punching structure 140 in the first horizontal direction. When the movable member 130 moves away from the punching structure 140 in the first horizontal direction, the movable member 130 drives the main body 310 to move to abut against the horizontal sidewall of the first positioning member 120, thereby realizing the first Positioning of workpiece 300 in a horizontal direction: At this time, the flange 320 of workpiece 300 is positioned on the shaping surface 110a of lower die base 110; When upper die 200 presses down to approach lower die 100, its first driving member 210 contacts the driving part 132 of movable member 130, pushing movable member 130 to approach punching structure 140 in the first horizontal direction, so that the positioning part 131 of movable member 130 can cooperate with punching structure 140 to complete punching of horizontal sidewall of workpiece 300. At the same time, the shaping member 220 of upper die 200 cooperates with the shaping surface 110a of lower die base 110 to shape flange 320 of workpiece 300. As can be seen from the above usage process, under the action of the elastic connector, after the main body 310 of the workpiece 300 is sleeved on the positioning part 131 and the first positioning part 120, the positioning part 131 can cooperate with the first positioning part 120 to position the workpiece 300 in the first horizontal direction. Subsequently, through the driving linkage between the movable part 130 and the upper die 200, when the movable part 130 cooperates with the first positioning part 120 to position the flange 320 of the workpiece 300, the movable part 130 can cooperate with the punching structure 140 to punch, so as to realize the simultaneous operation of the flange 320 shaping and the main body 310 punching, avoiding step-by-step processing and significantly improving efficiency.

[0026] refer to Figure 3 In some embodiments of this utility model, the lower die 100 further includes a second positioning member 150. Along a second horizontal direction, the second positioning member 150 is disposed on the side of the positioning part 131 opposite to the first positioning member 120. The positioning part 131, the first positioning member 120, and the second positioning member 150 allow the main body 310 to be simultaneously fitted onto them. It is understood that by adding a second positioning member 150 to the lower die 100, and by disposing of the second positioning member 150 along a second horizontal direction on the side of the positioning part 131 opposite to the first positioning member 120, the main body 310 of the workpiece 300 can be simultaneously fitted onto the positioning part 131, the first positioning member 120, and the second positioning member 150, forming a three-point positioning. This further enhances the horizontal stability of the workpiece 300, prevents deviation during punching, and improves punching accuracy.

[0027] refer to Figure 3 and Figure 4In some embodiments of this utility model, the driving part 132 is provided with a first abutting inclined surface 132a, and the first driving member 210 is provided with a driving inclined surface 210a adapted to the first abutting inclined surface 132a. It can be understood that the driving part 132 of the movable member 130 is provided with the first abutting inclined surface 132a, and the first driving member 210 of the upper mold 200 is correspondingly provided with the driving inclined surface 210a. When the upper mold 200 presses down, the driving inclined surface 210a slides into contact with the first abutting inclined surface 132a, converting the vertical pressure into a horizontal thrust, driving the movable member 130 to move along the first horizontal direction. The inclined surface transmission structure realizes the pressure direction conversion, simplifies the driving mechanism, and ensures that the movable member 130 is smoothly advanced.

[0028] refer to Figure 4 In some embodiments of this utility model, the punching structure 140 includes a transmission member 141 and a punching cutter 142. The transmission member 141 is slidably disposed on the lower die base 110 along a first horizontal direction. The punching cutter 142 is disposed on the side of the transmission member 141 near the positioning part 131. The side of the transmission member 141 away from the positioning part 131 is provided with a second abutting inclined surface 141a. The positioning part 131 is provided with a clearance hole 131a corresponding to the punching cutter 142. The upper die 200 has a second driving member 230. The second driving member 230 can push the second abutting inclined surface 141a when the upper die 200 is close to the lower die 100, so that the transmission member 141 drives the punching cutter 142 to approach the positioning part 131 and completes the punching of the main body 310 in conjunction with the clearance hole 131a. It is understandable that when the second driving member 230 of the upper die 200 presses down, it pushes the second abutting inclined surface 141a, causing the transmission member 141 to drive the punching tool 142 to move along the first horizontal direction until it penetrates the main body 310 of the workpiece 300 and enters the clearance hole 131a to complete the punching. The independently driven punching structure 140 avoids interference with the shaping action, and the horizontal punching reduces the risk of deformation of the workpiece 300.

[0029] like Figure 4As shown, in some embodiments, the punching structure 140 further includes an abutment block 143, which is connected to one end of the transmission member 141 near the positioning part 131 via an elastic buffer. The abutment block 143 is used to cooperate with the positioning part 131 to clamp the horizontal sidewall of the workpiece 300. Understandably, before the punching tool 142 punches the horizontal sidewall of the workpiece 300, the transmission member 141 drives the abutment block 143 to abut against the horizontal sidewall of the workpiece 300. As the transmission member 141 continues to move horizontally closer to the positioning part 131, the abutment block 143 abuts against the sidewall of the workpiece 300 through the elastic buffer. The abutment block 143 and the positioning part 131 cooperate to clamp the horizontal sidewall of the workpiece 300. By setting the elastic buffer, the rigid impact of the punching structure 140 on the horizontal sidewall can be reduced, thereby reducing the damage of the punching structure 140 to the surface of the workpiece 300. Furthermore, by the abutment block 143 and the positioning part 131 cooperating to clamp the horizontal sidewall of the workpiece 300, the stability of the punching tool 142 when punching the workpiece 300 is improved.

[0030] like Figure 4 As shown, in one embodiment, the abutment block 143 is provided with an insertion through hole 143a that allows the punching tool 142 to pass through. It is understood that when the abutment block 143 abuts against the horizontal sidewall of the workpiece 300, and the transmission member 141 continues to move horizontally closer to the positioning member, the punching tool 142 passes through the insertion through hole 143a to punch the horizontal sidewall of the workpiece 300. The inner wall of the insertion through hole 143a guides the movement path of the punching tool 142, preventing the punching tool 142 from deflecting and thus ensuring the punching accuracy of the punching tool 142.

[0031] like Figure 4 As shown, in some embodiments, the clearance hole 131a includes a first segment 131b and a second segment 131c. The cross-sectional dimension of the first segment 131b is smaller than that of the second segment 131c. The first segment 131b is adapted to the punching tool 142 to cooperate in punching to form a through hole. It can be understood that the clearance hole 131a is divided into a first segment 131b and a second segment 131c. The diameter of the first segment 131b matches that of the punching tool 142 to form a through hole, while the diameter of the second segment 131c is enlarged to accommodate the waste material after punching. By segmenting the clearance hole 131a, waste material blockage is avoided, ensuring continuous punching efficiency.

[0032] like Figure 4 As shown, in some embodiments, the positioning part 131 is provided with a discharge through hole 131d, which communicates with the clearance hole 131a. It can be understood that by providing a discharge through hole 131d and clearance hole 131a in the positioning part 131, the waste material is guided by both clearance hole 131a and discharge through hole 131d, resulting in smoother discharge.

[0033] Specifically, the clearance hole 131a extends along the first horizontal direction, and the blanking through hole 131d extends along the vertical direction.

[0034] like Figure 4 As shown, in one embodiment, the lower mold base 110 is provided with a blanking groove 110b, and the blanking through hole 131d is connected to the blanking groove 110b. It can be understood that by providing the blanking groove 110b to the lower mold base 110 and connecting the blanking through hole 131d to the blanking groove 110b, waste material can fall into the blanking groove 110b through the clearance hole 131a along the blanking through hole 131d, and finally be collected in the waste frame through the blanking groove 110b, thereby preventing the accumulation of chips inside the mold from affecting accuracy.

[0035] like Figure 4 As shown, in some embodiments of this utility model, the lower die 100 further includes an elastic reset member, which is connected to the transmission member 141 and the lower die base 110 respectively. The elastic reset member can provide the transmission member 141 with an elastic force to move away from the positioning part 131. It can be understood that after punching is completed, the upper die 200 leaves the lower die 100, and the elastic reset member pushes the transmission member 141 back to the initial position, thereby driving the punching tool 142 away from the positioning part 131, thereby avoiding the punching tool 142 from getting stuck and interfering with the part removal, and improving the efficiency of continuous operation.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
