Description

Technical Field

[0001] This application relates to the field of stamping equipment, and more particularly to a stamping die with in-die tapping. Background Technology

[0002] Stamping dies are specialized tools used in metal stamping processes to form metal sheets into specific shapes. Metal parts typically need to be stamped into shape using stamping dies first, and then tapped using tapping equipment to tap the through holes in the stamped sheet.

[0003] Traditional stamping dies are only responsible for stamping and cutting metal materials, while threading operations such as tapping need to be completed on separate tapping equipment. The existing processing flow is relatively cumbersome and the production efficiency is low. Utility Model Content

[0004] To improve production efficiency, this application provides a stamping die with in-mold tapping.

[0005] This application provides a stamping die with in-die tapping, which adopts the following technical solution:

[0006] A stamping die with in-mold tapping includes a conveying mechanism, a lifting mechanism, a stamping mechanism, a tapping mechanism, and a cutting mechanism. The conveying mechanism is used to convey sheet metal. The lifting mechanism includes a lifting rack and a transmission assembly. The tapping mechanism includes a tapping shank. The lifting rack is used for lifting and lowering and drives the tapping shank to rotate and lift through the transmission assembly. The stamping mechanism, tapping mechanism, and cutting mechanism are arranged along the conveying direction of the conveying mechanism.

[0007] By adopting the above technical solution, the stamping mechanism, tapping mechanism and cutting mechanism are integrated and arranged along the conveying direction to realize continuous automated processing of stamping, tapping and cutting processes, significantly reducing intermediate transfer links, improving production efficiency and reducing equipment footprint.

[0008] Optionally, both the stamping mechanism and the cutting mechanism are mounted on the lifting mechanism.

[0009] By adopting the above technical solution, the stamping mechanism and the cutting mechanism are integrated into the lifting mechanism, which simplifies the overall structure of the mold. Multiple mechanisms are driven to work synchronously by a single drive source, ensuring the synchronicity and coordination of the stamping and cutting actions, avoiding accuracy errors caused by the dispersion of mechanisms, and saving energy.

[0010] Optionally, the cutting mechanism includes a cutting seat and a positioning component disposed on the cutting seat, the positioning component being used to limit and fix the plate.

[0011] By adopting the above technical solution, the cutting mechanism is equipped with a positioning component, which limits and fixes the plate to prevent it from shifting during the cutting process, thereby improving cutting accuracy and product consistency and reducing scrap rate.

[0012] Optionally, the positioning component includes a positioning pin for insertion into a punching hole in the sheet metal.

[0013] By adopting the above technical solution, the design of inserting the positioning pin into the stamping hole of the plate can achieve precise positioning by utilizing the existing stamping hole, avoiding the complexity of additional positioning structures, and reducing damage to the surface of the plate.

[0014] Optionally, the positioning assembly further includes a fixing plate disposed on the cutting seat. The positioning pin is provided with a locking protrusion. The fixing plate has a rotating groove and an unlocking groove communicating with the rotating groove on its surface facing the positioning pin. The rotating groove is used for the positioning pin to be inserted, and the unlocking groove is used for the locking protrusion to be inserted. The side wall of the unlocking groove has a locking groove communicating with the rotating groove. The locking groove is used for the locking protrusion to be inserted and slide. There is a distance between the side wall of the locking groove and the surface of the fixing plate facing the positioning pin.

[0015] By adopting the above technical solution, the locking protrusion and the combination design of the rotating groove, unlocking groove and locking groove can realize the quick locking and unlocking of the positioning pin. The operation is convenient and highly stable, and the positioning failure caused by vibration during the processing can be avoided as much as possible.

[0016] Optionally, at least two locking protrusions are provided, and the at least two locking protrusions are arranged around the central axis of the positioning pin. At least two unlocking slots are also provided, and each unlocking slot corresponds to a different locking protrusion.

[0017] By adopting the above technical solution, the symmetrical distribution of multiple locking protrusions and corresponding unlocking grooves enhances the uniformity of force on the positioning pin, improves the reliability and torsional resistance of the locking structure, and ensures stability under long-term use.

[0018] Optionally, the positioning component further includes a cover plate, which is disposed on the fixed plate and located on the side of the fixed plate away from the positioning pin. The rotating groove and the locking groove both penetrate the contact surface between the fixed plate and the cover plate.

[0019] By adopting the above technical solution, a cover plate is added, and both the rotating groove and the locking groove penetrate the contact surface between the fixed plate and the cover plate, which facilitates the machining of grooves and holes on the fixed plate and reduces machining costs.

[0020] Optionally, the locking groove includes an initial segment, a transition segment, and a locking segment arranged sequentially and connected to each other. The transition segment is inclined, and the locking segment and the initial segment are staggered in the axial direction of the positioning pin.

[0021] By adopting the above technical solutions, the segmented design and staggered arrangement of the locking groove make the locking process of the positioning pin smoother and reduce mechanical wear; the inclined transition section guides the locking protrusion to slide naturally into the locking section, reducing manual intervention and improving operating efficiency. Moreover, the design of the inclined transition section can improve the locking effect of the locking groove on the positioning pin to a certain extent and reduce the probability that the locking protrusion will enter the initial section through the transition section during the working process.

[0022] Optionally, the initial segment is located on the side of the transition segment closer to the positioning pin, and the locking segment is located on the side of the transition segment away from the positioning pin.

[0023] By adopting the above technical solution, when the stamping die is working, it drives the positioning pin to move downward and insert into the stamping hole. At this time, the positioning pin will be subjected to an upward reaction force and tend to move upward. The transition section is set to be inclined upward, which reduces the possibility of the positioning pin sliding on the transition section and further improves the locking effect.

[0024] Optionally, the locking groove wall is provided with an elastic element.

[0025] By adopting the above technical solution, an elastic element is added to the wall of the locking groove to buffer the impact force when the positioning pin locks, reduce component wear, provide a flexible locking effect, facilitate locking operation, and further improve the locking effect.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Enables continuous automated processing of stamping, tapping and cutting processes, improving production efficiency while reducing equipment footprint;

[0028] 2. The design of the locking protrusion in conjunction with the rotating groove, unlocking groove, and locking groove enables the positioning pin to be quickly locked and unlocked, making operation convenient and highly stable;

[0029] 3. The transition section is tilted upwards to reduce the possibility of the positioning pin sliding on the transition section, thereby further improving the locking effect. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] Example 1:

[0038] Embodiment 1 of this application discloses a stamping die with in-die tapping. (See also...) Figure 1 The stamping die with in-mold tapping includes a conveying mechanism 1, a lifting mechanism 2, a stamping mechanism 3, a tapping mechanism 4, and a cutting mechanism 5. The conveying mechanism 1 is used to convey the metal sheet. The tapping mechanism 4 includes a tapping shank 41, which is used to tap the punched holes on the metal sheet. The stamping mechanism 3 includes a stamping rod 31, which is used to punch holes in the metal sheet. The cutting mechanism 5 includes a cutting blade 53, which is used to cut the processed metal sheet. The stamping mechanism 3, the tapping mechanism 4, and the cutting mechanism 5 are arranged along the conveying direction of the conveying mechanism 1.

[0039] Reference Figure 2 The stamping die with in-mold tapping also includes a frame 8 and a support frame 9, with the support frame 9 fixedly mounted on the frame 8. The lifting mechanism 2 includes a lifting rack 21, a transmission assembly 22, a lifting drive source 23, and a lifting platform 24. The lifting rack 21 is fixedly mounted on the lifting platform 24, and the transmission assembly 22 is fixedly mounted on the support frame 9. The lifting drive source 23 drives the lifting platform 24 to rise and fall, and the lifting rack 21 is used for rising and falling, driving the tapping tool 41 to rotate and rise and fall via the transmission assembly 22.

[0040] Reference Figure 1 The conveying mechanism 1 is mounted on the frame 8, and can use a conveyor belt to transport the metal sheet. The lifting platform 24 is located directly above the conveying mechanism 1. The stamping mechanism 3 and the cutting mechanism 5 are both fixedly mounted on the lifting platform 24 and move up and down with the lifting platform 24.

[0041] Reference Figure 1 The cutting mechanism 5 includes a cutting seat 51 and a positioning component 52. The cutting seat 51 is fixedly mounted on the lifting platform 24. The positioning component 52 includes a positioning pin 521, which is used to insert into the punching hole of the metal sheet to limit the position of the metal sheet. In other embodiments, the positioning component 52 may also include a positioning rod, which is used to press against the surface of the metal sheet. The positioning component 52 may also include a gripper, which is used to clamp and fix the metal sheet. Any method that can limit and fix the metal sheet is acceptable.

[0042] The working principle of a stamping die with in-mold tapping in Embodiment 1 of this application is as follows: a metal sheet is sequentially conveyed by a conveying mechanism 1 to the stamping mechanism 3, the tapping mechanism 4 and the cutting mechanism 5. A lifting mechanism 2 drives the stamping mechanism 3, the tapping mechanism 4 and the cutting mechanism 5 to descend. A metal sheet is first stamped by the stamping mechanism 3, then the tapping mechanism 4 taps the stamping holes on the metal sheet, and finally the cutting mechanism 5 cuts the metal sheet to obtain the finished product.

[0043] This application integrates the stamping mechanism 3, the tapping mechanism 4, and the cutting mechanism 5 along the conveying direction to achieve continuous automated processing of stamping, tapping, and cutting processes. This significantly reduces intermediate transfer links, improves production efficiency, and reduces the equipment footprint. Furthermore, by driving multiple mechanisms to work synchronously through a single drive source, the synchronicity and coordination of stamping and cutting actions are ensured. Precise positioning is achieved using existing stamping holes, avoiding the complexity of additional positioning structures and reducing damage to the surface of the sheet metal.

[0044] Example 2:

[0045] Reference Figure 3 and Figure 4 Unlike Embodiment 1, in this embodiment, the positioning pin 521 is detachably connected to the cutting seat 51. The positioning assembly 52 also includes a cover plate 526 and a fixing plate 522 fixedly installed on the cutting seat 51. The fixing plate 522 is fixedly connected to the cover plate 526, the fixing plate 522 is located below the cover plate 526, and the bottom surface of the cover plate 526 abuts against the top surface of the fixing plate 522.

[0046] Reference Figure 5The fixing plate 522 has a rotating groove 523 and two unlocking grooves 524 on its surface facing the positioning pin 521. The rotating groove 523 has a circular cross-section and is used for the end of the positioning pin 521 to be inserted and rotated. The unlocking grooves 524 are connected to the rotating groove 523. Two locking protrusions 6 are integrally formed on the outer peripheral surface of the end of the positioning pin 521 near the fixing plate 522. The two locking protrusions 6 are evenly distributed along the outer peripheral surface of the positioning pin 521, and the two unlocking grooves 524 are used for different locking protrusions 6 to be inserted. In other embodiments, the number of locking protrusions 6 can be three, four, etc., and the number of unlocking grooves 524 is set corresponding to the number of locking protrusions 6.

[0047] Reference Figure 5 The unlocking slot 524 has a locking slot 525 on its sidewall, which communicates with the rotating slot 523. The two locking slots 525 extend around the central axis of the rotating slot 523, and their extension directions are consistent, either clockwise or counterclockwise. There is a distance between the sidewall of the locking slot 525 and the surface of the fixing plate 522 facing the positioning pin 521; that is, the locking slot 525 does not penetrate the bottom surface of the fixing plate 522, and each locking slot 525 communicates with only one unlocking slot 524. The locking slot 525 is used for the insertion of the locking protrusion 6, and when the positioning pin 521 rotates, the locking protrusion 6 slides within the locking slot 525. In other embodiments, the locking slot 525 does not have to be an arc-shaped slot; it can be a square slot or other shapes, as long as the locking slot 525 covers the sliding path of the locking protrusion 6.

[0048] Reference Figure 5 The locking groove 525 includes an initial segment 527, a transition segment 528, and a locking segment 529 arranged sequentially and connected to each other. The transition segment 528 extends obliquely upward, such that the locking segment 529 is located above the initial segment 527 in the axial direction of the rotating groove 523. In other embodiments, the transition segment 528 may extend obliquely downward, such that the locking segment 529 is located below the initial segment 527 in the axial direction of the rotating groove 523.

[0049] Reference Figure 5 The rotating groove 523 extends axially through both surfaces of the fixed plate 522, and the locking section 529 of the locking groove 525 extends axially through the contact surface between the fixed plate 522 and the cover plate 526, that is, through the top surface of the fixed plate 522. In other embodiments, the locking groove 525 may not include the transition section 528, the locking groove 525 extends horizontally as a whole, the unlocking groove 524 extends axially through both surfaces of the fixed plate 522, and the locking groove 525 extends axially through the top surface of the fixed plate 522.

[0050] Reference Figure 1An elastic element 7 is fixedly installed on the side wall of the locking section 529. The elastic element 7 is made of rubber and is hemispherical. The elastic element 7 is used for compression by the locking protrusion 6. After the positioning pin 521 is installed on the fixing plate 522, the locking protrusion 6 is located between the bottom wall of the locking section 529 and the elastic element 7, thereby limiting the locking protrusion 6 in the horizontal direction. In other embodiments, the locking groove 525 may not include the transition section 528. The locking groove 525 extends horizontally as a whole, and the elastic element 7 is fixedly installed on the side wall of the locking groove 525.
