Description

Technical Field

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

[0002] The descriptions in this section provide background information relating to this disclosure and do not constitute prior art.

[0003] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0004] Existing stamping dies generally lack positioning functions, requiring operators to manually assist in positioning before stamping. This makes it difficult to ensure operator safety, and because manual assistance or the use of other auxiliary stamping tools makes it challenging to guarantee that the stamping results meet usage standards. Utility Model Content

[0005] The purpose of this utility model is to provide a stamping die with a positioning function. The stamping die is clamped and positioned, and then the part to be stamped on the stamping die is positioned by a left and right centering positioning device that is snapped into the outer wall of the stamping plate, so as to avoid displacement of the part during the stamping process. This solves the technical problem that stamping dies generally do not have a positioning function, which leads to the need for workers to assist in positioning. When workers manually assist or use other auxiliary stamping, it is difficult to ensure that the stamping effect meets the usage standard.

[0006] This utility model provides a stamping die with positioning function, including: A rectangular bracket, with rectangular rods vertically fixed at each of the four corners of its top surface; The top plate is fixedly assembled to the upper ends of the four rectangular rods; A hydraulic cylinder is vertically fixedly mounted in the middle of the top surface of the top plate, and a stamping plate is fixedly mounted through the top plate at its telescopic end. The cross-section of the stamping plate is an inverted T-shape. The left and right centering positioning device has an inverted T-shaped through hole in the center of its top surface corresponding to the stamping plate; The stamping plate is inserted and snapped into the inverted T-shaped through hole from bottom to top; A guide support structure is assembled between the left and right centering positioning device and the top surface of the rectangular bracket; The rectangular bracket is longitudinally fitted with a front and rear positioning structure for the stamping die on its top surface.

[0007] As a further optimization, in order to push and clamp the stamping die on the top surface of the rectangular bracket towards the center to achieve centering positioning in the left and right directions, the left and right centering positioning device includes: A rectangular plate, with a first strip-shaped groove horizontally formed on the front side of its bottom surface; A bidirectional threaded rod is rotatably fitted on the left side of the inner wall of the first strip-shaped groove; A handle is passed through the right side of the rectangular plate and is fixedly connected to the right end of the bidirectional threaded rod. The outer wall of the bidirectional threaded rod is symmetrically screwed with first rectangular columns on the left and right sides, which are slidably assembled in the first strip groove.

[0008] As a further optimization, in order to increase the clamping area and improve the clamping stability by using a strip clamping plate, a second strip groove is laterally opened on the rear side of the bottom surface of the rectangular plate, and connecting rods are rotatably assembled on the left and right sides of its inner wall. The connecting rod has second rectangular columns symmetrically and slidably sleeved on the left and right sides of its outer wall. Strip clamps are fixedly fitted to the lower ends of the inner surfaces of the first and second rectangular columns on the same side.

[0009] As a further optimization, in order to facilitate gripping the crank handle to rotate the bidirectional threaded rod, the handle handle is specifically a crank handle.

[0010] As a further optimization, in order to guide the vertical movement of the left-right centering positioning device, the guide support structure includes: Through holes are provided at the four corners of the top surface of the rectangular plate; The top surface of the rectangular bracket is vertically fixed with a guide rod corresponding to the through hole, and the guide rod is slidably inserted into the corresponding through hole.

[0011] As a further optimization, to avoid direct contact between the strip clamping plate and the stamping die on the top surface of the rectangular bracket, and to prevent wear on the outer wall of the stamping die, a rubber layer is attached and fixed to the inner side of the strip clamping plate.

[0012] As a further optimization, in order to position the stamping die on the top surface of the rectangular bracket by front and rear abutment, the front and rear positioning structure of the stamping die includes: A strip-shaped wedge-shaped groove is longitudinally formed on the top surface of the rectangular support; Both the front and rear sides of the inner cavity of the strip-shaped wedge-shaped groove are slidably engaged with wedge-shaped sliders, and their top surfaces are lower than the top surfaces of the rectangular bracket. The upper end of the wedge-shaped slider is vertically fixed with a screw, and a sleeve is sleeved on its outer wall. A fixing nut is screwed onto the upper end of the screw, which pushes the lower end of the sleeve against the top surface of the rectangular bracket. Positioning crossbars are fixedly fitted to the front and rear side walls of the sleeve.

[0013] As a further optimization, to prevent the fixing nut from loosening after screwing, a washer is fitted onto the upper end of the screw, which is located between the lower end of the fixing nut and the upper end of the sleeve.

[0014] As a further optimization, to provide stable support for the device, the rectangular support includes: A rectangular flat plate, with vertically fixed supports at each of the four corners of its bottom surface.

[0015] As a further optimization, in order to improve the mechanical strength of the lower end of the rectangular support, a crossbeam is fixedly assembled between the left and right pillars on the same side.

[0016] This utility model provides a stamping die with positioning function through improvements, which has the following improvements and advantages compared with the prior art: The stamping die is clamped and positioned on the top surface of the rectangular bracket at the corresponding stamping plate using a front and rear positioning structure. A hydraulic cylinder drives the stamping plate to rise and fall, which in turn drives the left and right centering positioning device attached to the outer wall to rise and fall. The left and right centering positioning device is used to position the part to be stamped on the stamping die. The left and right centering positioning device is longitudinally limited by a guide support structure. Then the stamping plate is pushed to continue to move down and disengage from the T-shaped through hole to stamp the part to be stamped. No manual auxiliary positioning or other auxiliary tools are required, so that the stamping effect meets the usage standards. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a stamping die with positioning function, comprising: A rectangular bracket 1, with rectangular rods 2 vertically fixed at each of the four corners of its top surface; Top plate 3, which is fixedly assembled to the upper ends of four rectangular rods 2; A hydraulic cylinder 8 is vertically fixedly mounted in the middle of the top surface of the top plate 3. Its telescopic end passes through the top plate 3 and is fixedly mounted with a stamping plate 7. The cross-section of the stamping plate 7 is an inverted T-shape. The left and right centering positioning device 4 has an inverted T-shaped through hole 6 in the middle of its top surface corresponding to the stamping plate 7; The stamping plate 7 is inserted from bottom to top into the inverted T-shaped through hole 6; A guide support structure is assembled between the left and right centering positioning device 4 and the top surface of the rectangular bracket 1; The top surface of the rectangular bracket 1 is longitudinally fitted with a front and rear positioning structure 9 for the stamping die.

[0024] Specifically, in this embodiment, the rectangular bracket 1 is used to support the entire device, the top plate is used to install the hydraulic cylinder 8, and the hydraulic cylinder 8 is connected to an external hydraulic system for use. Furthermore, the stamping die is clamped and positioned on the top surface of the rectangular bracket 1 at the position corresponding to the stamping plate 7 by the front and rear positioning structure 9 of the stamping die. The hydraulic cylinder 8 drives the stamping plate 7 to rise and fall. The stamping plate 7 drives the left and right centering positioning device 4, which is clamped on the outer wall, to rise and fall accordingly. The left and right centering positioning device 4 is used to position the part to be stamped on the stamping die. The left and right centering positioning device 4 is longitudinally limited by the guide support structure. Then the stamping plate 7 is pushed to continue to move down and disengage from the T-shaped through hole 6 to stamp on the part to be stamped. No manual auxiliary positioning or other auxiliary tools are required, so that the stamping effect meets the usage standard. More specifically, the cross-section of the stamping plate 7 is an inverted T-shape, and the top center of the left and right centering positioning device 4 is provided with an inverted T-shaped through hole 6 corresponding to the stamping plate 7. The stamping plate 7 is inserted and locked into the inverted T-shaped through hole 6 from bottom to top. This design allows the inverted T-shaped through hole 6 on the left and right centering positioning device 4 to be sleeved on the outer wall of the stamping plate 7 and kept locked. When the left and right centering positioning device 4 clamps the part to be stamped and cannot move up and down, the stamping plate 7 continues to move down and pass through the inverted T-shaped through hole 6. Understandably, after the device is used, the left and right centering positioning device 4 is released from its limit on the part to be stamped, and then the stamping plate 7 is moved up to drive the left and right centering positioning device 4 to rise and reset, and the part to be stamped is taken out from the stamping die. The stamping die is positioned and clamped by the front and rear positioning structure 9 of the stamping die, and the positioning is released to facilitate its replacement.

[0025] In some embodiments, the left and right centering positioning device 4 includes: A rectangular plate 41 has a first strip groove 43 horizontally opened on the front side of its bottom surface; A bidirectional threaded rod 44 is rotatably fitted on the left side of the inner wall of the first strip groove 43; A handle 45 extends through the right side of the rectangular plate 41 and is fixedly connected to the right end of the bidirectional threaded rod 44. The outer walls of the bidirectional threaded rod 44 are symmetrically threaded with first rectangular posts 46 on the left and right sides, which are slidably assembled in the first strip groove 43. A second strip groove 47 is horizontally opened on the rear side of the bottom surface of the rectangular plate 41, and a connecting rod 48 is rotatably assembled on the left and right sides of its inner wall. The second rectangular column 42 is symmetrically and slidably sleeved on the left and right sides of the outer wall of the connecting rod 48; Strip clamps 49 are fixedly fitted to the lower inner sides of the first rectangular column 46 and the second rectangular column 42 on the same side.

[0026] Specifically in this embodiment, rotating the handle 45 drives the bidirectional threaded rod 44 to rotate. The rotation of the bidirectional threaded rod 44 drives the first rectangular posts 46 on the left and right sides to move towards or away from each other along the first strip groove 43. The first rectangular posts 46 move towards each other to clamp and position the stamping part. Furthermore, during the movement of the first rectangular column 46, the second rectangular column 42 is driven to slide along the connecting rod 48 through the connection of the strip clamp 49. The strip clamp 49 increases the clamping area and improves the clamping stability.

[0027] In some embodiments, the handle 45 is specifically a rocker arm, which facilitates gripping the rocker arm to rotate the bidirectional threaded rod 44.

[0028] In some embodiments, the guide support structure includes: Through holes 51 are provided at the four corners of the top surface of rectangular plate 41; A guide rod 5 is vertically fixedly mounted on the top surface of the rectangular bracket 1 corresponding to the through hole 51, and the guide rod 5 is slidably inserted into the corresponding through hole 51.

[0029] Specifically, in this embodiment, the outer diameter of the guide rod 5 is the same as the inner diameter of the through hole 51. The two slide together to guide and limit the up and down movement of the left and right centering positioning device 4. When the stamping plate 7 moves down after disengaging from the T-shaped through hole 6, under the premise that the left and right centering positioning device 4 is clamped and fixed in the upper and lower positions of the part to be stamped, the limiting of the guide rod 5 prevents the left and right centering positioning device 4 from lateral displacement, and plays a supporting role for the left and right centering positioning device 4, ensuring its positioning effect on the part to be stamped.

[0030] In some embodiments, a rubber layer is attached to the inner side of the strip clamp 49. The rubber layer prevents the strip clamp 49 from directly contacting the stamping die on the top surface of the rectangular bracket 1, thus preventing wear on the outer wall of the stamping die.

[0031] In some embodiments, the front and rear positioning structure 9 of the stamping die includes: A strip-shaped wedge-shaped groove 91 is longitudinally formed on the top surface of the rectangular support 1; The front and rear sides of the inner cavity of the strip-shaped wedge-shaped groove 91 are slidably engaged with wedge-shaped sliders 92, the top surface of which is lower than the top surface of the rectangular support 1. A screw 93 is vertically fixed at the upper end of the wedge-shaped slider 92, and a sleeve 94 is sleeved on its outer wall. A fixing nut 95 is screwed onto the upper end of the screw 93, and the lower end of its pushing sleeve 94 abuts against the top surface of the rectangular bracket 1. Positioning crossbars 96 are fixedly fitted on the front and rear side walls of sleeve 94; A washer is fitted onto the upper end of the screw 93, which is located between the lower end of the fixing nut 95 and the upper end of the sleeve 94.

[0032] Specifically in this embodiment, the wedge-shaped slider 92 slides back and forth in the strip-shaped wedge-shaped groove 91, and the tightening of the fixing nut 95 pushes the lower end of the sleeve 94 to abut against the top of the rectangular bracket 1 to limit and fix the wedge-shaped slider 92 at its current position; Furthermore, loosen the fixing nut 95, slide the wedge slider 92 in the strip wedge groove 91, so that the positioning crossbar 96 on the outer wall of the sleeve 94 abuts against the outer wall of the stamping die, and the positioning crossbars 96 on the outer walls of the front and rear sleeves 94 abut against the same side of the outer wall of the stamping die. Then tighten the fixing nut 95 to limit and fix the current position of the wedge slider 92, and clamp and position the stamping die at the position of the upper and lower corresponding stamping plates 7. More specifically, after the screw is loosened and the fixing nut 95 is tightened, the sliding wedge slider 92 drives the positioning crossbar 96 away from the stamping die, at which point other stamping dies can be replaced; Understandably, the washer is designed to prevent the fixing nut from loosening after being screwed in at a 95° angle.

[0033] In some embodiments, the rectangular support 1 includes: A rectangular flat plate 11 has vertically fixed support columns 12 at each of its four corners on the bottom surface. A crossbeam 13 is fixedly installed between the left and right side pillars 12.

[0034] Specifically in this embodiment, the rectangular flat plate 11 and the pillars 12 at the four corners of the bottom surface constitute a rectangular support 1, which serves as an operating table; Furthermore, the crossbeam 13 enhances the mechanical strength of the lower end of the rectangular support 1.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
