Description

Technical Field

[0001] This utility model relates to the field of punching technology, and in particular to a tongue-cutting forming mold. Background Technology

[0002] During the processing of sheet metal parts, for sheet metal parts with internal groove structures, it is sometimes necessary to punch inwardly recessed tongues on the side walls of the sheet metal parts. If the punching structure directly punches the side walls of the sheet metal parts, the entire side walls of the sheet metal parts will deform inward under the action of the punching structure. If a positioning structure is used to pass through the groove structure of the sheet metal parts to provide internal support for the side walls of the sheet metal parts, in this case, the positioning structure needs to be provided with clearance holes to facilitate the subsequent forming of the tongues on the side walls. However, after the punching structure punches the tongues on the side walls of the sheet metal parts, the tongues will pass through the clearance holes, making it difficult to remove the sheet metal parts from the positioning structure. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a tongue-cutting forming mold. After the tongue-cutting forming mold of this embodiment punches out the tongue on the side wall of the sheet metal part, it can reduce the deformation of the side wall of the sheet metal part and facilitate the removal of the punched sheet metal part from the positioning structure.

[0004] A tongue-cutting forming mold according to an embodiment of the present invention includes an upper mold and a lower mold. The upper mold has a first driving member and a second driving member. The lower mold includes a lower mold base, a positioning structure, and a punching structure. The positioning structure allows sheet metal parts to be fitted. The positioning structure includes an abutment member and a positioning member. The positioning member is movably arranged in the vertical direction and is connected to the lower mold base through an elastic connector. The elastic connector is used to provide an upward elastic force to keep the positioning member. The horizontally opposite ends of the positioning member are respectively provided with clearance holes and guide slopes. The guide slopes abut against the abutment member. The punching structure... The positioning member is located on the side opposite to the abutment member and is slidably mounted on the lower die base in the horizontal direction. The end of the punching structure opposite to the positioning member is provided with an abutment slope for abutting against the second driving member. When the upper die and the lower die approach each other under the action of external force, the positioning member can overcome the elastic force of the elastic connector under the push of the first driving member, so as to push the side wall of the sheet metal part close to the punching structure along the guide slope. The punching structure can approach and cooperate with the clearance hole under the push of the second driving member, so as to punch out a tongue recessed in the clearance hole on the side wall of the sheet metal part.

[0005] A tongue-cutting forming mold according to an embodiment of the present utility model has at least the following technical effects:

[0006] During the use of the tongue-cutting forming mold of this application, the sheet metal part is sleeved on the positioning structure of the lower mold. The positioning part is kept in an upward state under the elastic force of the elastic connector, and its guide slope is tightly fitted with the abutment. The punching structure is located in the initial position away from the positioning part. When the upper mold presses down, the first driving member pushes the positioning part down through the sheet metal part. The positioning part overcomes the elastic force of the elastic connector and slides along the extension direction of the guide slope, simultaneously pushing the side wall of the sheet metal part horizontally closer to the punching structure. At the same time, the second driving member contacts the abutment slope of the punching structure to push it through the abutment slope. The punching structure is horizontally close to the positioning part so that the punching structure mates with the clearance hole. It punches an inwardly recessed cutting tongue on the side wall of the sheet metal part, and the cutting tongue is embedded in the clearance hole. After the upper die is raised, the punching structure is disengaged from the sheet metal part. The positioning part is reset and raised under the action of the elastic connector. During the upward movement of the positioning part, the side wall of the sheet metal part is moved away from the punching structure and the sheet metal part is moved upward to disengage from the abutment. At this time, the sheet metal part can move smoothly relative to the positioning part in the horizontal direction under the action of external force, so that the cutting tongue can disengage from the clearance hole, thereby facilitating the smooth disengagement of the sheet metal part from the positioning part in the vertical direction. As can be seen from the above usage process, by moving the positioning component downward to push the side wall of the sheet metal part horizontally, the overall deformation of the side wall is avoided during punching. After the cutting tongue is embedded in the clearance hole, the positioning component is lifted by the elastic connector so that the sheet metal part can move smoothly relative to the positioning component under the action of external force, so that the cutting tongue can be separated from the clearance hole, thereby solving the problem of part jamming. Therefore, after the cutting tongue forming mold of this application punches the cutting tongue on the side wall of the sheet metal part, it can reduce the deformation of the side wall of the sheet metal part and facilitate the removal of the punched sheet metal part from the positioning structure.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] The following is for reference. Figures 1 to 6 A tongue-cutting forming mold according to an embodiment of the present utility model will be described in detail.

[0032] refer to Figures 1 to 4According to an embodiment of the present invention, a tongue-cutting forming mold includes an upper mold 100 and a lower mold 200. The upper mold 100 has a first driving member 110 and a second driving member 120. The lower mold 200 includes a lower mold base 210, a positioning structure 220, and a punching structure 230. The positioning structure 220 allows sheet metal parts to be fitted. The positioning structure 220 includes an abutment member 221 and a positioning member 222. The positioning member 222 is movably arranged in the vertical direction and is connected to the lower mold base 210 through an elastic connector 223. The elastic connector 223 is used to provide an elastic force to keep the positioning member 222 upward. The horizontally opposite ends of the positioning member 222 are respectively provided with a clearance hole 222a and a guide slope 222b. The guide slope 222b is connected to the abutment member 221. The punching structure 230 is located on the side of the positioning member 222 away from the abutting member 221 and is slidably mounted on the lower die base 210 in the horizontal direction. The end of the punching structure 230 away from the positioning member 222 is provided with an abutting slope 230a for abutting against the second driving member 120. When the upper die 100 and the lower die 200 approach each other under the action of external force, the positioning member 222 can overcome the elastic force of the elastic connecting member 223 under the push of the first driving member 110, so as to push the side wall of the sheet metal part close to the punching structure 230 along the guide slope 222b. The punching structure 230 can approach and cooperate with the relief hole 222a under the push of the second driving member 120, so as to punch out a tongue recessed in the relief hole 222a on the side wall of the sheet metal part.

[0033] During the use of the tongue-cutting forming mold of this application, the sheet metal part is sleeved on the positioning structure 220 of the lower mold 200. The positioning part 222 is kept in an upward state under the elastic force of the elastic connector 223, and its guide slope 222b is tightly fitted with the abutment part 221. The punching structure 230 is located in the initial position away from the positioning part 222. When the upper mold 100 is pressed down, the first driving member 110 pushes the positioning part 222 downward through the sheet metal part. The positioning part 222 overcomes the elastic force of the elastic connector 223 and slides along the extension direction of the guide slope 222b, simultaneously pushing the side wall of the sheet metal part horizontally close to the punching structure 230. At the same time, the second driving member 120 contacts the abutment slope 230a of the punching structure 230, so as to pass through the abutment slope 230a. 230a pushes the punching structure 230 horizontally close to the positioning member 222 so that the punching structure 230 cooperates with the clearance hole 222a to punch out an inwardly recessed cutting tongue on the side wall of the sheet metal part. The cutting tongue is embedded in the clearance hole 222a. After the upper die 100 is raised, the punching structure 230 is disengaged from the sheet metal part. The positioning member 222 is reset and lifted under the action of the elastic connector 223. During the lifting process of the positioning member 222, the side wall of the sheet metal part is moved away from the punching structure 230, and the sheet metal part is lifted upward to disengage from the abutment member 221. At this time, the sheet metal part can move smoothly relative to the positioning member 222 in the horizontal direction under the action of external force so that the cutting tongue disengages from the clearance hole 222a, thereby facilitating the sheet metal part to smoothly disengage from the positioning member 222 in the vertical direction. As can be seen from the above usage process, the lowering of the positioning member 222 pushes the side wall of the sheet metal part to be horizontally positioned, avoiding the overall deformation of the side wall during punching. After the cutting tongue is inserted into the clearance hole 222a, the positioning member 222 is lifted by the elastic connector 223, so that the sheet metal part can move smoothly relative to the positioning member 222 under the action of external force, so that the cutting tongue can be separated from the clearance hole 222a, thereby solving the problem of part jamming. Therefore, after the cutting tongue forming mold of this application punches the cutting tongue on the side wall of the sheet metal part, it can reduce the deformation of the side wall of the sheet metal part and facilitate the removal of the punched sheet metal part from the positioning structure 220.

[0034] refer to Figure 4 In some embodiments of this utility model, the punching structure 230 includes a transmission member 231 and a punching cutter 232. The transmission member 231 is slidably disposed on the lower die base 210 in the horizontal direction, and an abutting inclined surface 230a is disposed on the transmission member 231. The punching cutter 232 is disposed on the side of the transmission member 231 near the positioning member 222 and is used to punch a tongue on the side wall of the sheet metal part. It can be understood that the second driving member 120 acts on the abutting inclined surface 230a of the transmission member 231, converting the vertical pressure into a horizontal thrust, driving the transmission member 231 to slide closer to the positioning member 222. The transmission member 231 drives the punching cutter 232 to move horizontally closer to the positioning member 222. The punching cutter 232 pushes the positioning member 222 to deform into the clearance hole 222a, so as to punch a tongue on the side wall of the sheet metal part.

[0035] like Figures 4 to 6 As shown, in some embodiments, the punching structure 230 further includes an abutment block 233, which is connected to the end of the transmission member 231 near the positioning member 222 via an elastic buffer member. The abutment block 233 is used to cooperate with the abutment member 221 to clamp the horizontal sidewall of the sheet metal part. Understandably, before the punching tool 232 punches the horizontal sidewall of the sheet metal part, the transmission component 231 drives the abutment block 233 to abut against the horizontal sidewall of the sheet metal part. As the transmission component 231 continues to move horizontally closer to the positioning component 222, the abutment block 233 abuts against the sidewall of the sheet metal part through the elastic buffer component. The abutment block 233 and the abutment component 221 work together to clamp the horizontal sidewall of the sheet metal part. By setting the elastic buffer component, the rigid impact of the punching structure 230 on the horizontal sidewall can be reduced, thereby reducing the damage of the punching structure 230 to the surface of the sheet metal part. Furthermore, by the abutment block 233 and the abutment component 221 working together to clamp the horizontal sidewall of the sheet metal part, the stability of the punching tool 232 when punching the sheet metal part is improved.

[0036] like Figure 4 and Figure 6 As shown, in one embodiment, the abutment block 233 is provided with an insertion through hole 233a that allows the punching tool 232 to pass through. It is understood that when the abutment block 233 abuts against the horizontal sidewall of the sheet metal part, and the transmission member 231 continues to move horizontally closer to the positioning member 222, the punching tool 232 passes through the insertion through hole 233a to punch the horizontal sidewall of the sheet metal part. The inner wall of the insertion through hole 233a guides the movement path of the punching tool 232, preventing the punching tool 232 from deflecting and thus ensuring the shape accuracy of the cut tongue formed by the punching tool 232.

[0037] like Figure 4 and Figure 6 As shown, in some embodiments, the punching structure 230 includes multiple punching cutters 232, and the abutment member 221 has multiple clearance holes 222a on its side near the punching cutters 232. The punching cutters 232 and clearance holes 222a are arranged in a one-to-one correspondence. It can be understood that each punching cutter 232 can be synchronously embedded into each clearance hole 222a under the drive of the transmission member 231, so as to process multiple tongues on the horizontal sidewall of the sheet metal part at one time. By setting multiple punching cutters 232 to punch synchronously, the processing efficiency can be further improved, while ensuring the positional accuracy between the multiple tongues.

[0038] refer to Figures 4 to 6In some embodiments of this utility model, the abutment member 221 is provided with a guide groove 221a, and the positioning member 222 is slidably disposed in the guide groove 221a. The guide inclined surface 222b is fitted against the bottom surface of the guide groove 221a. It can be understood that the positioning member 222 slides along the guide groove 221a of the abutment member 221, and its guide inclined surface 222b is always fitted against the bottom of the guide groove 221a, so that the sliding trajectory of the positioning member 222 is always constrained by the groove wall of the guide groove 221a, thereby reducing the probability of the sheet metal part having a positioning deviation due to the displacement of the positioning member 222 during the sliding process.

[0039] like Figures 4 to 6 As shown, in some embodiments, the positioning structure 220 further includes a limiting block 224, which is disposed on the abutment member 221. The positioning member 222 has an abutment portion 222c, and the lower end of the limiting block 224 can abut against the abutment portion 222c to prevent the positioning member 222 from disengaging upward from the guide groove 221a. It can be understood that when the upper mold 100 leaves the lower mold 200, causing the positioning member 222 to move upward under the action of the elastic connector 223, the abutment portion 222c of the positioning member 222 can abut against the lower end of the limiting block 224, thereby preventing the positioning member 222 from disengaging upward from the guide groove 221a, thus preventing the positioning member 222 from dislodging due to excessive rebound of the elastic connector 223, and ensuring the stability of the movement of the positioning member 222.

[0040] like Figures 4 to 6 As shown, in some embodiments, the upper end face of the abutment member 221 is provided with a mounting groove 221b, which communicates with the guide groove 221a. The positioning member 222 is provided with a sliding groove 222d. The limiting block 224 is embedded in the mounting groove 221b and partially extends into the sliding groove 222d. The bottom surface of the sliding groove 222d is slidably engaged with the limiting block 224, and the lower side wall of the sliding groove 222d forms an abutment portion 222c. It can be understood that by embedding part of the structure of the limiting block 224 into the sliding groove 222d of the positioning member 222, and by making the bottom surface of the sliding groove 222d slidably engaged with the limiting block 224, the positioning member 222 can slide more stably relative to the abutment member 221. By using the lower side wall of the sliding groove 222d as the abutment portion 222c, the overall structure of the positioning member 222 is simpler and easier to manufacture.

[0041] In some embodiments, the limiting block 224 is detachably disposed within the mounting slot 221b. For example, as... Figures 4 to 6As shown, the positioning structure 220 also includes a threaded connector. The limiting block 224 is provided with an insertion hole 224a. The threaded connector passes through the insertion hole 224a and is threadedly connected to the abutment member 221. It can be understood that since the limiting block 224 can be independently installed and removed from the mounting groove 221b, it is convenient to replace the limiting block 224 after wear, reducing the maintenance cost of the positioning structure 220. By detachably connecting the limiting block 224 to the abutment member 221, it is convenient to install and remove the positioning member 222.

[0042] refer to Figure 4 In some embodiments of this utility model, the lower die 200 further includes a second elastic reset member 240. The second elastic reset member 240 is connected to the punching structure 230 and the lower die base 210 respectively, and is used to provide an elastic force to keep the punching structure 230 away from the positioning member 222. It can be understood that after punching is completed, the upper die 100 leaves the lower die 200, and the second elastic reset member 240 pushes the punching structure 230 back to its initial position, avoiding the punching structure 230 from getting stuck and interfering with the part removal, thus improving the efficiency of continuous operation.

[0043] 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.
