Description

Technical Field

[0001] This utility model relates to the field of metal stamping technology, and in particular to a side-cutting device for metal stamping dies with a structure to prevent chip diffusion. Background Technology

[0002] Side-cutting equipment for metal stamping dies is a mechanical device specifically used in the metal stamping process to shear, trim, or drill holes on the sides of workpieces. It is widely used in precision manufacturing processes in industries such as automotive, home appliances, and electronics. This equipment is typically installed on the side of the stamping die or integrated into the die structure. Through lateral shearing actions, it processes burrs, irregular edges, or pre-designed structures on the sides of stamped parts to improve dimensional accuracy, appearance quality, and consistency in subsequent assembly. Its structural design must balance processing efficiency, die life, and operational safety, making it an important auxiliary device for improving product yield and automation.

[0003] In the field of metal stamping, side cutting is a common and essential processing step used to remove burrs or irregular flanges from the side edges of stamped parts. Currently, most side cutting equipment directly utilizes stamping shearing force for leveling. While this saves processing steps and improves efficiency, it has significant shortcomings in practical application: Firstly, the sheared metal fragments scatter and fly everywhere under impact, increasing workshop cleanup difficulty and posing a serious threat to operator safety. Secondly, high-intensity shearing force can easily lead to die misalignment or surface scratches and dents on the workpiece, thus reducing the processing accuracy and overall pass rate of the stamped parts. Therefore, its use has certain limitations.

[0004] Based on this, we propose a metal stamping die side-cutting device with an anti-chip diffusion structure to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a metal stamping die side-cutting device with an anti-chip diffusion structure, which can solve the safety hazards caused by metal chip splashing during the side-cutting process and the problems of die guide misalignment and workpiece surface defects caused by high-intensity shearing force.

[0007] To solve the above technical problems, this utility model provides a metal stamping die side-cutting device with an anti-chip diffusion structure, which adopts the following technical solution: it includes a stamping bracket, a first stamping assembly is installed inside the stamping bracket, the first stamping assembly is installed on the top of the stamping bracket, and a second stamping assembly is provided at the bottom of the stamping bracket. The second stamping assembly includes a lower stamping component, and a stamping side-cutting component is provided on the outer periphery of the lower stamping component.

[0008] The lower stamping component includes a lower stamping die, a shock-absorbing support plate is installed at the bottom of the lower stamping die, a fixed base plate is installed at the bottom of the shock-absorbing support plate, and positioning slots are respectively opened around the fixed base plate.

[0009] Optionally, the inner sides of the stamping die and the shock-absorbing support plate are provided with storage grooves, and the four corners of the two sets of storage grooves are hinged to support arm plates, and spring shock absorbers are connected between the eight sets of support arm plates.

[0010] Optionally, the stamping side-cutting component includes a side-cutting blade, and a positioning plate is installed at the bottom of the side-cutting blade. The positioning plate matches the positioning slot structure, and the positioning plate and the positioning slot are engaged in a snap-fit ​​relationship.

[0011] Optionally, the first stamping assembly includes an upper stamping die, both ends of which are equipped with guide rails, and the bottom of both ends of the upper stamping die are respectively provided with retaining grooves.

[0012] Optionally, two sets of hydraulic cylinders are installed on the top of the stamping bracket, and two sets of guide grooves are opened on both sides of the inner wall of the stamping bracket. The guide grooves are matched with the guide rail structure, and the guide grooves and guide rails are in sliding fit. Stamping buffer components are also provided on both sides of the bottom of the stamping bracket.

[0013] Optionally, the stamping buffer component includes four sets of piston grooves, which are respectively opened on both sides of the stamping bracket. Each of the four sets of piston grooves is connected to a piston rod, which matches the structure of the piston groove. A shock-absorbing top support is connected between the tops of two sets of piston rods, which matches the structure of the retaining groove. A piston damping block is installed at the bottom of each of the four sets of piston grooves, which matches the structure of the piston groove. The piston damping block and the piston groove are in a damped sliding fit. A compression spring is also sleeved in the middle of the four sets of piston grooves.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. The metal stamping side-cutting equipment designed in this scheme features side-cutting blades that can be locked and positioned around the outer perimeter of the lower stamping die. By utilizing the shrinkage adjustment between the lower stamping die and the shock-absorbing support plate, the tip of the side-cutting blade can be precisely exposed. During the stamping process, after the metal workpiece is stamped by the upper stamping die, the exposed tip of the side-cutting blade can effectively side-cut burrs or irregular areas extruded around the metal workpiece. This design not only achieves efficient trimming of burrs and irregular edges on the sides of the metal workpiece, ensuring the dimensional accuracy and appearance quality of the workpiece, but also effectively prevents metal chips from flying everywhere, thus avoiding threats to the personal safety of operators, reducing the difficulty of workshop cleaning, and achieving a safe and stable stamping side-cutting processing environment.

[0016] 2. The metal stamping side-cutting equipment designed in this scheme, by adding guide slides to both ends of the upper stamping die and opening guide slide grooves on both sides of the inner wall of the stamping support to match the structure, forms a sliding fit between the two, thereby guiding and limiting the upper stamping die during the stamping process, preventing the upper stamping die and the lower stamping die from shaking or misalignment during stamping collision. At the same time, in conjunction with the stamping buffer components added to both sides of the bottom of the stamping support, these components, through the coordinated cooperation of piston grooves, piston rods, shock-absorbing plates, piston damping blocks, and compression springs, can provide secondary buffering for both ends of the upper stamping die, further reducing the violent vibrations generated during stamping collision. Through the optimized design of these structures, the stability and precision of the stamping process can be effectively improved, ensuring the smooth operation of the metal stamping side-cutting equipment, improving the overall product qualification rate, and achieving efficient, accurate, and stable metal stamping processing results.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Refer to Figures 1 to 8This utility model provides an embodiment of a metal stamping die side-cutting device with an anti-chip diffusion structure, comprising a stamping bracket 1, a first stamping assembly 2 installed inside the stamping bracket 1, the first stamping assembly 2 being installed on the top of the stamping bracket 1, and a second stamping assembly 3 provided at the bottom of the stamping bracket 1, the second stamping assembly 3 including a lower stamping component 4, stamping side-cutting components 5 provided around the outer periphery of the lower stamping component 4, the lower stamping component 4 including a lower stamping die 6, a shock-absorbing support plate 7 installed at the bottom of the lower stamping die 6, a fixed base plate 8 installed at the bottom of the shock-absorbing support plate 7, and positioning positions respectively opened around the periphery of the fixed base plate 8. The slot 9, in this metal stamping side-cutting equipment, through the combined use of the receiving groove 10, the support arm plate 11, and the spring shock absorber 12, can buffer and offset the vibration waves generated by the stamping collision between the upper stamping die 15 and the lower stamping die 6. At the same time, it can also utilize the shrinkage adjustment between the lower stamping die 6 and the shock-absorbing support plate 7 to facilitate the exposure of the blade tip of the side-cutting blade 13 installed around the outer periphery of the lower stamping die 6. The exposed blade tip can side-cut the burrs or irregular parts extruded around the stamped metal workpiece. This side-cutting process can also effectively prevent the side-cut metal chips from flying everywhere.

[0029] Both the lower stamping die 6 and the shock-absorbing support plate 7 have storage grooves 10 on their inner sides. Support arm plates 11 are hinged to the four corners of both sets of storage grooves 10. Spring shock absorbers 12 are connected between the eight sets of support arm plates 11. Through the combined use of the storage grooves 10, support arm plates 11, and spring shock absorbers 12, the vibration waves generated by the stamping collision between the upper stamping die 15 and the lower stamping die 6 can be buffered and offset. The shrinkage adjustment between the lower stamping die 6 and the shock-absorbing support plate 7 can also be utilized. The stamping side-cutting component 5 includes a side-cutting blade 13. A positioning plate 14 is installed at the bottom of the side-cutting blade 13. The positioning plate 14 matches the structure of the positioning slot 9. The positioning plate 14 and the positioning slot 9 are engaged by a snap-fit ​​mechanism. Through the snap-fit ​​mechanism between the positioning plate 14 and the positioning slot 9, multiple sets of side cutting blades 13 can be respectively limited and snapped around the outer periphery of the stamping lower die 6. The stamping lower die 6 can be disassembled, connected, repaired, and replaced according to the usage of the side cutting blades 13. The first stamping assembly 2 includes an upper stamping die 15. Guide rails 16 are installed at both ends of the upper stamping die 15. The bottom of both ends of the upper stamping die 15 is also provided with a stop groove 17. By adding guide rails 16 to both ends of the upper stamping die 15, the stamping upper die 15 can be guided and limited during the stamping process.

[0030] Two sets of hydraulic cylinders 18 are installed on the top of the stamping bracket 1. Two sets of guide grooves 19 are opened on both sides of the inner wall of the stamping bracket 1. The guide grooves 19 and guide rails 16 are structurally matched and have a sliding fit. Stamping buffer components 20 are also provided on both sides of the bottom of the stamping bracket 1. Through the structural design of the sliding fit between the guide grooves 19 and guide rails 16, the upper stamping die 15 can be guided and limited at both ends during stamping, which can prevent the upper stamping die 15 from shaking or misaligning when it collides with the lower stamping die 6. The stamping buffer component 20 includes four sets of piston grooves 21. The four sets of piston grooves 21 are respectively opened on both sides of the stamping bracket 1. A piston rod 22 is connected inside each of the four sets of piston grooves 21. The piston rod 22 and the piston groove 21 are structurally matched. A shock-absorbing top support 23 is connected between the tops of the piston rods 22. The shock-absorbing top support 23 matches the structure of the retaining groove 17. A piston damping block 24 is installed at the bottom of each of the four sets of piston grooves 21. The piston damping block 24 matches the structure of the piston groove 21. The piston damping block 24 and the piston groove 21 are in a damped sliding fit. A compression spring 25 is also sleeved in the middle of the four sets of piston grooves 21. The stamping buffer component 20, through the cooperation of the piston grooves 21, piston rods 22, shock-absorbing top support 23, piston damping block 24, and compression spring 25, can play an elastic buffering role at both ends of the stamping upper die 15, which can absorb and cancel the vibration waves generated by the stamping collision between the stamping upper die 15 and the stamping lower die 6, and can prevent the stamping upper die 15 and the stamping lower die 6 from violently vibrating when they collide.

[0031] Working Principle: The metal stamping side-cutting equipment designed in this scheme mainly consists of a stamping bracket 1, a first stamping assembly 2, and a second stamping assembly 3. The second stamping assembly 3 includes a lower stamping component 4 and a side-cutting component 5. The lower stamping component 4 uses positioning slots 9 respectively opened around the base plate 8, and positioning plates 14 respectively installed at the bottom of the side-cutting blades 13. Because the positioning plates 14 and positioning slots 9 are structurally matched, and the positioning plates 14 and positioning slots 9 are in a snap-fit ​​engagement, multiple sets of side-cutting blades 13 can be respectively limited and snapped onto the outer periphery of the lower stamping die 6. When the upper stamping die 15 is stamped on the top of the lower stamping die 6 under the force of two sets of hydraulic cylinders 18, it can... The metal workpiece placed on top of the stamping die 6 is stamped and formed. The stamping die 6, through the cooperation of the receiving groove 10, the support arm plate 11, and the spring shock absorber 12, can buffer and offset the vibration waves generated by the stamping collision between the stamping upper die 15 and the stamping lower die 6. At the same time, the shrinkage adjustment between the stamping lower die 6 and the shock-absorbing support plate 7 can facilitate the exposure of the tip of the side cutting blade 13 installed around the outside of the stamping lower die 6. The exposed blade tip can side cut the burrs or irregular parts squeezed out around the stamped metal workpiece. This side cutting process can also effectively prevent the side-cut metal chips from flying everywhere.

[0032] The metal stamping side-cutting equipment designed in this scheme uses guide rails 16 installed at both ends of the upper stamping die 15 and guide grooves 19 opened on both sides of the inner wall of the stamping support 1. Since the guide grooves 19 and guide rails 16 are structurally matched and have a sliding fit, they can guide and limit the two ends of the upper stamping die 15 during stamping, preventing shaking or misalignment when the upper stamping die 15 collides with the lower stamping die 6. In conjunction with the stamping buffer components 20 installed on both sides of the bottom of the stamping support 1, the stamping buffer components 20, through the cooperation of piston groove 21, piston rod 22, shock-absorbing top support 23, piston damping block 24, and compression spring 25, can also provide secondary buffering for the two ends of the upper stamping die 15 during stamping, preventing violent vibration when the upper stamping die 15 collides with the lower stamping die 6 during stamping, thereby ensuring the stability of the metal stamping side-cutting equipment.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
