Description

Technical Field

[0001] This utility model relates to the field of clamp forming, and in particular to a clamp forming tooling. Background Technology

[0002] In traditional clamp manufacturing processes, clamps are primarily made using bending machines. The material is typically Q235 flat steel with a thickness of 4mm, 5mm, or 6mm, and the dimensions are determined by the specific requirements of the leaf spring, such as 25mm or 30mm. While this processing method can meet the basic clamp forming requirements, it has significant shortcomings in practical applications. On the one hand, existing bending machines can only process flat steel materials one piece at a time, resulting in low work efficiency. On the other hand, when processing flat steel materials of different specifications, manual repositioning of the materials is required, which cannot guarantee positioning accuracy. Deviations may occur, making it difficult to ensure the symmetry of the processed clamps. This often leads to inconsistent left and right heights during installation, thus affecting the normal use of the leaf spring. Utility Model Content

[0049] Reference Figures 1 to 4As shown, a clamp forming tool is mainly used to stamp flat steel materials to form clamps in practical applications. It includes a lower forming component 1, an upper forming component 2 adapted to the lower forming component 1, and an anti-deviation mechanism 3 and a blocking mechanism 4 disposed on the lower forming component 1.

[0050] Specifically, the lower forming assembly 1 is used to place the flat steel material. The lower forming assembly 1 includes a lower mold base 11 and a lower forming block 12 disposed on the lower mold base 11. The lower mold base 11 is a planar plate structure to provide a flat mounting platform and improve the stability during clamp forming. The lower forming block 12 is fixedly disposed on the lower mold base 11, and both ends of the forming groove 13 penetrate the lower forming block 12, making it a flared through-groove structure. The through-groove is the forming groove 13, and the shape of the forming groove 13 is the shape of the clamp forming.

[0051] In this embodiment, the upper forming component 2 is positioned above the lower forming component 1 and connected to a hydraulic press. A hydraulic press is a stamping device that uses a hydraulic cylinder to generate compressive force. It includes components such as hydraulic connecting rods and crankshafts. The hydraulic system converts the pressure energy of hydraulic oil into mechanical energy, thereby driving the upper forming mechanism to reciprocate up and down. This, in conjunction with the lower forming mechanism, applies pressure to the flat steel material, achieving plastic deformation or separation of the flat steel material, thus completing the stamping of the clamp. The upper forming mechanism includes a die shank 21, an upper die base 22 connected to the die shank 21, and an upper forming block 23 connected to the upper die base 22. More specifically, the die shank 21 is fixedly connected to the hydraulic press. Driven by the hydraulic press, the die shank 21 reciprocates vertically along its axis, thereby driving the entire upper forming component 2 to reciprocate vertically. The upper die base 22 is fixedly connected to the die shank 21. The bottom end of the upper die base 22 is provided with an embedding groove, which is a through groove. The upper forming block 23 is movably connected to the upper mold base 22. That is, the top of the upper forming block 23 is provided with a connecting block that matches the embedding groove. By sliding the connecting block into the embedding groove, the upper forming block 23 and the upper mold base 22 are slidably connected. The operator can replace or repair the upper forming block 23 by pulling it out of the embedding groove. Since the upper forming block 23 can only slide horizontally and cannot move vertically in the embedding groove, the upper forming block 23 can reciprocate vertically with the upper mold base 22 when the hydraulic punch is working. The upper forming block 23 is adapted to the lower forming block 12. Through the cooperation between the upper forming block 23 and the lower forming block 12, the flat steel material is stamped and bent to complete the production of the clamp.

[0052] In this embodiment, since the flat steel material is subject to impact force and may shift during stamping, the anti-deviation mechanism 3 is fixedly mounted on the lower die base 11. During stamping, it limits the flat steel material and prevents it from shifting. The anti-deviation mechanism 3 includes a support module 31, which is fixedly mounted on the lower die base 11 and arranged perpendicularly to the forming groove 13. When multiple flat steel materials are being stamped, the unstamped portions can be placed on the support module 31 to reduce the impact on the operator holding the flat steel material during stamping. Specifically, the support module 31 includes a slide 311 and a support block 312 connected to the slide 311. The slide 311 has an L-shaped structure, with its bottom fixedly connected to the lower die base 11 and its top extending towards the end away from the lower forming block 12 to form a straight slide rail. The support block 312 has an overall T-shaped structure and is located on the top of the slide block 311. The support block 312 is movably connected to the slide block 311 by inserting into the slide rail. The bottom end of the support block 312 is also provided with a fixing component to fix the support block 312 on the slide block 311 and prevent the support block 312 from moving. For example, the fixing component is a bolt and a nut. The bolt is fixedly connected to the bottom end of the support block 312. When it is necessary to adjust the position of the support block 312, the operator moves the position of the support block 312 on the slide rail. After the position is determined, the nut is screwed into the bolt so that the nut abuts against the surface of the slide rail and the nut is tightened. Under the friction between the nut and the slide rail, the position of the support block 312 is fixed, so that the support block 312 can be adapted to flat steel materials of different lengths and is more stable when placing flat steel materials.

[0053] In this embodiment, since the clamp requires changing molds according to different specifications during processing, which is time-consuming, labor-intensive, and has low processing efficiency, the anti-deviation mechanism 3 also includes a positioning module 32 to adapt to plates of different widths. The positioning module 32 is disposed on the lower forming block 12. After multiple flat steel materials are placed on the lower forming block 12, the flat steel materials are restricted and positioned to prevent them from shifting during stamping. Specifically, the lower forming block 12 has two mounting slots symmetrically arranged around the forming groove 13 as the axis, and the two mounting slots are respectively located on both sides of the forming groove 13. The positioning module 32 includes two limiting components, which are respectively disposed in the two mounting slots. For ease of description, one limiting component is used here. The limiting component includes several positioning slots 321, several positioning blocks 322 adapted to the several positioning slots 321, a top plate 323 disposed in the mounting slot, and several abutment members 324 adapted to the top plate 323. Specifically, the groove opening of the mounting groove is recessed inward at even intervals on the side near the forming groove 13 to form several notches, which are the positioning grooves 321. A plurality of positioning blocks 322 are disposed within positioning grooves 321, and the positioning blocks 322 are adapted to the positioning grooves 321, that is, the top of the positioning block 322 is higher than the top plane of the lower forming block 12 to form a protrusion. One side of the positioning block 322 abuts against the mounting groove, and the other end is adapted to the groove opening of the positioning groove 321. When the flat steel material is placed on the lower forming block 12, the protrusion in two adjacent positioning blocks 322 restricts the flat steel material, thereby locking and positioning the flat steel material. The positioning blocks 322 can be adaptively adjusted according to the flat steel material to be stamped. That is, when the width of the flat steel material becomes wider, the distance between two adjacent positioning blocks 322 can be adjusted. For example, one of the two adjacent positioning blocks 322 can be placed in a positioning groove 321 further away from the other positioning block 322, or the number of positioning blocks 322 can be reduced to increase the distance between two adjacent positioning blocks 322. The top plate 323 is movably disposed within the mounting groove. The top plate 323 is adapted to several positioning blocks 322, that is, one side of the top plate 323 abuts against the positioning blocks 322 to fix and restrict the positioning blocks 322 within the positioning groove 321. Several abutting members 324 are disposed on the lower forming block 12 and adapted to the top plate 323 to abut against one end of the top plate 323, fixing and restricting the top plate 323 within the mounting groove. For example, the abutting member 324 is a screw. A screw hole adapted to the screw is opened on one side of the mounting groove. By inserting the screw into the screw hole, one end of the screw abuts against the top plate 323, and rotating the screw, the screw holds the top plate 323 in place, thus fixing the top plate 323 and preventing it from loosening, thereby reducing the possibility of the positioning blocks 322 loosening.

[0054] In some preferred embodiments, the supporting module 31 is further provided with an auxiliary positioning component 33 adapted to the positioning module 32 for further positioning of the flat steel material. The auxiliary positioning component 33 includes a plurality of countersunk holes 331 and a plurality of positioning pins 332 adapted to the countersunk holes 331. The plurality of countersunk holes 331 are evenly arranged on the support block 312, and the countersunk holes 331 are adapted to the positioning grooves 321, that is, the number of countersunk holes 331 is the same as the number of positioning grooves 321, and their opening positions on the support block 312 are on the same axis as the central axis of the positioning grooves 321. The plurality of positioning pins 332 are movably disposed in the countersunk holes 331, and the number of positioning pins 332 is adapted to the number of positioning blocks 322, that is, the positioning pins 332 can also be adaptively adjusted according to the flat steel material.

[0055] In this embodiment, the blocking mechanism 4 is disposed on the lower die base 11 and located between the lower forming block 12 and the slide block 311. During the flat steel material stamping operation, it is used to prevent the unstamped portion of the flat steel material from warping, reducing the possibility of injury to workers. The blocking mechanism 4 includes a first column 41, a rotating rod 42 connected to the first column 41, and a second column 43 adapted to the rotating rod 42. Specifically, the first column 41 is fixedly disposed on the lower die base 11, and one end of the rotating rod 42 is hinged to the top end of the first column 41, so that the rotating rod 42 can rotate around the hinge point with the first column 41 as the axis, and the rotation direction of the rotating rod 42 is perpendicular to the extension direction of the slide rail. During the flat steel material stamping operation, it blocks the flat steel material to prevent it from warping. The second column 43 is fixedly mounted on the lower mold base 11 at the end away from the first column 41. The top of the second column 43 is provided with a locking member, which is adapted to the rotating rod 42 for locking and fixing the rotating rod 42. For example, the locking member is a pin. The second column 43 is provided with a socket hole adapted to the pin. The rotating rod 42 at the end away from the first column 41 is also provided with a through hole. By inserting the pin into the socket hole and the through hole, the rotating rod 42 is fixed. After the flat steel material is stamped, the worker can pull out the pin to release the rotating rod 42, which makes it easier for the worker to take out the flat steel material, increases work convenience, and improves work efficiency.

[0056] In this embodiment, by setting an anti-deviation mechanism 3 on the lower forming component 1, and by using the positioning module 32 in the anti-deviation mechanism 3 to adapt to flat steel materials of different specifications, the drawback of needing to reposition flat steel materials of different specifications during die casting is solved, thereby achieving the technical effect of improving the symmetry and flatness of the clamp and ensuring the efficiency of assembly.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
