Description

Technical Field

[0001] This utility model relates to a punching device for automotive stamping dies, and more particularly to a modular wedge mechanism installed between a fixed lower die and a movable upper die. Background Technology

[0002] A wedge mechanism for stamping dies is a mechanical mechanism that converts vertical force into horizontal or inclined force to achieve specific processing or operational functions. It is widely used in the automotive stamping die industry, especially when large metal panels such as car bodies are stamped using a fixed lower die and a moving upper die. During stamping, the wedge mechanism installed in the die can be used to punch holes or flanging the sides of the stamped product.

[0003] With the continuous development of automobile production technology, automobile manufacturers are constantly raising their performance requirements for stamping dies. As one of the core components of stamping dies, the existing wedge mechanism for stamping dies can no longer meet the overall technical requirements of stamping dies and urgently needs improvement.

[0004] The machining force required for a wedge mechanism in stamping dies varies depending on the material and thickness of the metal panel (workpiece) and the mounting position of the machining tool on the wedge slider of the wedge mechanism. When the mounting position of the machining tool deviates from the center of the wedge, the machining force of the wedge mechanism decreases. To maximize the machining force of the wedge mechanism, its width, height, length, and machining angle need to be considered. To fully utilize the machining force, these various values ​​of the wedge mechanism need to be optimized and balanced. Existing wedge mechanisms for stamping dies do not adequately optimize the relationship between the width, height, length, and machining angle of the wedge mechanism, resulting in an inability to fully utilize its machining force.

[0005] To save manufacturing costs, both automobile manufacturers and mold manufacturers are committed to reducing the number of processes in stamping dies to reduce the number of stamping equipment and shrinking the size of stamping dies to reduce material costs and processing time. Therefore, while meeting processing force parameters and ensuring operational stability, it is necessary to recalculate, design, and plan the overall structure of the existing wedge mechanism for stamping dies to achieve greater compactness and obtain a smaller volume.

[0006] Currently, most mainstream stamping processes utilize automated stamping production lines. This necessitates that the wedge mechanism used in stamping dies must have a long service life and ensure stable operation throughout its service life. Therefore, while calculating, designing, and planning the overall structure of the wedge mechanism for stamping dies, it is also essential to conduct thorough calculations, tests, and inspections of key factors such as the material, construction, and interaction relationships of each component.

[0007] The present invention aims to provide a novel wedge mechanism for stamping dies to solve the problems existing in the existing wedge mechanisms. Utility Model Content

[0008] This utility model aims to provide a wedge mechanism for stamping dies. This wedge mechanism is the result of a redesign of the overall structure and the dimensions and materials of each component based on the basic principles of this type of product. It solves the problem that the processing force of the wedge mechanism in stamping dies is not fully optimized, thus failing to fully utilize the processing force. The specific technical solution is as follows:

[0009] This utility model provides a wedge mechanism for stamping dies, comprising a wedge base, a wedge slider, and a wedge driver arranged sequentially from top to bottom.

The two guide covers are fixed on both sides of the wedge base body to provide lateral support for the wedge slider when it slides. The anti-detachment baffle is installed below the wedge base to prevent the wedge slider held by the guide covers from sliding backward. The buffer component is located below the anti-detachment baffle to provide a buffering effect between the wedge base and the wedge slider when the wedge mechanism is working.

[0016] According to the above-mentioned wedge mechanism for stamping dies provided by this utility model, when the wedge mechanism for stamping dies is working, it converts the vertical die pressure P into a wedge mechanism working force F. The angle between the direction of the wedge mechanism working force F and the horizontal direction is the processing angle θ1 when the wedge mechanism for stamping dies is working. The angle between the direction of the motion trajectory of the first sliding part of the wedge mechanism and the horizontal direction is θ2, where θ2 represents the angle between the wedge and the horizontal direction. The relationship between the wedge and the horizontal direction θ2 and the die pressure P, the wedge mechanism working force F, and the processing angle θ1 can be expressed by the following formula:

[0046] like Figure 1As shown, the wedge mechanism 1 for stamping dies provided by this utility model includes a wedge base 2, a wedge slider 3, and a wedge driver 4 arranged sequentially from top to bottom. A first planar sliding surface 2a is provided below the wedge base 2. The left and right sides of the wedge slider 3 are slidably connected to the wedge base 2 via guide covers 7. A second planar sliding surface 3a is provided above the wedge slider 3, which slides in contact with the first planar sliding surface 2a. A working surface 3e for mounting machining tools is provided in front of the wedge slider 3. A recessed first V-shaped sliding surface 3b is provided below the wedge slider 3. A retraction elastic component is provided in the upper middle part of the wedge slider 3. The wedge driver 4 is provided with... A raised second V-shaped sliding surface 4a is formed by sliding contact with the recessed first V-shaped sliding surface 3b. The first planar sliding surface 2a and the second planar sliding surface 3a constitute the first sliding part, and the first V-shaped sliding surface 3b and the second V-shaped sliding surface 4a constitute the second sliding part. The wedge base 2 and the wedge slider 3 are slidably connected through the first sliding part, and the wedge slider 3 and the wedge drive 4 are slidably connected through the second sliding part. The first V-shaped sliding surface 3b and the second V-shaped sliding surface 4a fit tightly together when sliding. The first V-shaped sliding surface 3b and the second V-shaped sliding surface 4a ensure that the wedge slider 3 can move on the set working trajectory when the wedge mechanism 1 is working.

[0047] The wedge base 2 includes a wedge base body 2c and a wear-resistant plate 2b. The top of the wedge base body is provided with a positioning component 2e and a mounting hole 2d for positioning and fixing the moving mold of a stamping die that reciprocates in the vertical direction. The wear-resistant plate 2b is arranged obliquely and installed on the lower part of the wedge base body 2c. The lower part of the wear-resistant plate 2b has a first planar sliding surface 2a. Further, the wedge base body 2c and the wear-resistant plate 2b are integrally formed, or they can be separately formed. In this embodiment, the wear-resistant plate 2b and the wedge base body are non-integral sliding components and can be freely detached and installed onto the mounting surface of the wedge base body using bolts or the like.

[0048] The wedge base 2 also includes a wedge base body 2c, a wear-resistant plate 2b with self-lubricating properties, two guide covers 7, an anti-detachment baffle 6, and a buffer component 6a. The two guide covers 7 are fixed on both sides of the wedge base body 2c and provide lateral support for the wedge slider 3 when it slides. The anti-detachment baffle 6 is installed below the wedge base 2 to prevent the wedge slider 3 held by the guide covers 7 from sliding backward. The buffer component 6a is located below the anti-detachment baffle 6 and provides a buffering effect between the wedge base 2 and the wedge slider 3 when the wedge mechanism is working. The wedge base body 2c and the wear-resistant plate 2b with self-lubricating properties are integrally formed or separately formed.

[0049] The wedge actuator 4 includes a wedge actuator base 4c and a trapezoidal wedge actuator slider 4b. The wedge actuator slider 4b is mounted on the mounting surface of the wedge actuator base 4c. The wedge actuator slider 4b has a raised second V-shaped sliding surface 4a, which slides in contact with a recessed trapezoidal first V-shaped sliding surface 3b. Furthermore, the wedge actuator slider 4b and the wedge actuator base 4c are non-integral sliding components, and the slider can be freely detached and mounted to the mounting surface of the wedge actuator base 4c by bolts or the like. Alternatively, the wedge actuator base 4c and the trapezoidal wedge actuator slider 4b can be integrally formed.

[0050] The wedge slider 3 has a second planar sliding surface 3a above it that slides in contact with the first planar sliding surface 2a; the wedge slider 3 has a recessed first V-shaped sliding surface 3b below it, which slides in contact with the protruding wedge drive slider 4b of the wedge driver 4 through the second V-shaped sliding surface 4a. The wedge base 2 slidably supports the structure of the wedge slider 3 and applies force to the wedge slider 3 in the retraction direction by the retraction elastic component 5.

[0051] The wedge slider 3 has a working surface for mounting machining tools at its front. The upper middle part of the wedge slider has a mounting hole, in which a retraction elastic component 5 is installed. The retraction elastic component 5 also contacts the inner wall of the wedge base at the corresponding position. The upper part of the wedge slider 3 has a sliding part 3c. The side of the sliding part 3c has a groove 3g that slides with the guide cover plate. The lower part of the wedge slider side wall 3d has a groove 8a for mounting the forced pull-back block 8.

[0052] Two guide plates 7 are fixed to both sides of the wedge base body, providing lateral support for the wedge slider 3 when it slides. A retraction elastic component 5 is used to restore the wedge slider 3 to its initial position when the wedge base 2 is raised; the guide plates 7 provide lateral support for the wedge slider 3 when it slides; an anti-disengagement baffle 6 prevents the wedge slider 3 held by the guide plates 7 from sliding backward; and a forced pull-back block 8 prevents the machining tool of the wedge slider 3 from being stuck by the panel and unable to retract.

[0053] Depending on the operating parameters of the wedge mechanism for stamping dies, the retraction elastic component 5 can be a rectangular helical spring or a nitrogen spring. A mounting hole is provided in the upper middle part of the wedge slider 3, and the retraction elastic component 5 is installed in the mounting hole. When a rectangular helical spring is used for the retraction elastic component 5, a spring guide pin 5a is provided in the mounting hole of the wedge slider 3. One end of the spring guide pin 5a is fixed to the body of the wedge slider assembly, and the other end does not contact the wedge base assembly. In this embodiment, the labeling of the nitrogen spring guide pin 5a is only for illustrative purposes. When the wedge base 2 rises, the wedge slider 3 can return to its initial position through the rebound force of the retraction elastic component. When the wedge mechanism for stamping dies is working, regardless of the type of retraction elastic component, one end of the retraction elastic component will contact the inner wall of the corresponding position on the wedge base.

[0054] A sliding part 3c is provided above the wedge slider 3. The sliding part 3c is provided with a groove 3g that slides and engages with the guide cover plate 7. The upper end of the guide cover plate 7 is fixed to the side wall of the wedge base 2. The L-shaped locking part at the lower end of the guide cover plate 7 is fitted into the groove 3g. Through the guide cover plates 7 provided on both sides, the wedge slider 3 can slide back and forth within a set range in a direction parallel to the first planar sliding contact surface 2a and the second planar sliding contact surface 3a, while not disengaging from the wedge base assembly when the wedge mechanism for stamping die is working.

[0055] The forced pull-back block 8 is C-shaped. The upper end of the forced pull-back block 8 is fixedly installed on the wedge slider side wall 3d of the wedge slider 3. The L-shaped locking part at the lower end of the forced pull-back block 8 can move along the lower edge of the second V-shaped sliding surface 4a. The width of the front end of the second V-shaped sliding surface 4a is greater than that of the rear end. When the wedge slider 3 moves forward, the forced pull-back blocks 8 on the left and right sides move accordingly. When the machining tool of the wedge slider 3 is stuck by the panel and cannot retract, as the wedge base 2 moves upward, it drives the wedge slider 3 to move upward, which in turn drives the forced pull-back block 8 to retract along the lower edge of the second V-shaped sliding surface 4a. The forced pull-back block 8 gives the wedge slider 3 an impact force, which releases the jamming between the machining tool and the panel and moves the wedge slider 3 back to its initial position.

[0056] The wedge mechanism 1 for stamping dies provided by this utility model, during operation, has a wedge base 2 fixedly installed with the upper die 9 of the stamping die, and a wedge driver 4 fixedly installed with the lower die 10 of the stamping die. The upper die 9 is mounted on the press slide 9a, and the lower die 10 is mounted on the lower worktable 10a of the press. The wedge base 2 and the upper die 9 reciprocate together in the vertical direction from the top dead center to the bottom dead center. Therefore, the wedge slide 3 reciprocates in the machining direction along the front-back direction, causing the machining tool mounted on the working surface 3e of the wedge slide 3 to reciprocate in the machining direction, performing punching and flanging on the panel placed in the die. Therefore, wear will occur in the first sliding part composed of the first planar sliding surface 2a and the second planar sliding surface 3a, and in the second sliding part composed of the first V-shaped sliding surface 3b and the second V-shaped sliding surface 4a.

[0057] When the movement of the wedge slider 3 in the machining direction of the wedge driver 4 causes an increase in the wear of the wedge slider 3 and the wedge driver 4, the position of the machining tool mounted on the wedge slider 3 also gradually changes from the initial machining position. When the machining position of the machining tool exceeds the allowable range, defective products will appear on the machined panel.

[0058] When the surface pressure of the sliding part is constant, the wear characteristics of the second V-shaped sliding surface 4a and the first V-shaped sliding surface 3b are determined by the combination of the material, processing method, heat treatment of the wedge-driven slider 4b and the first V-shaped sliding surface 3b, and the filling density of graphite 4d on the second V-shaped sliding surface 4a or the first V-shaped sliding surface 3b. The filling density is the proportion of the area occupied by graphite on the sliding surface.

[0059] In other words, wear is composed of several parameters, and the Holm wear equation (1) is generally known as follows:

[0060] M ・・・ (1)

[0061] Wear amount VM is directly proportional to the friction coefficient Z, load PZ, and friction distance LM, and inversely proportional to the hardness PH. Since wear depends on the friction coefficient, load, and friction distance, each factor must be optimized to minimize wear amount.

[0062] Because high precision is required for adjusting the relative position between the machining tool and the panel, the wear between the second V-shaped sliding surface 4a and the first V-shaped sliding surface 3b must be minimal.

Figure 2bThis is a working mode diagram of another wedge mechanism for stamping dies according to this utility model. W represents the width of the wedge mechanism for stamping dies, P represents the die pressure on the wedge mechanism for stamping dies, N represents the length of the mounting surface of the wedge base for stamping dies, H represents the closed height of the wedge mechanism for stamping dies, that is, the height of the wedge mechanism 1 for stamping dies when the wedge slider 3 moves to the lowest allowable position under the pressure of the wedge base 2, L represents the stamping stroke, that is, the height difference between the height of the wedge mechanism for stamping dies at the moment when the first V-shaped sliding surface and the second V-shaped sliding surface begin to contact and the lowest working height, θ1 represents the processing angle of the wedge mechanism for stamping dies, the angle between the direction of force applied during operation and the horizontal direction, which is the processing angle for the wedge mechanism for stamping dies to perform its work, θ2 represents the angle between the wedge of the wedge mechanism for stamping dies and the horizontal direction, S represents the working stroke of the wedge mechanism for stamping dies, that is, the maximum stroke of the wedge slider 3 moving forward along the direction of force applied during operation, S′ represents the spring stroke, that is, the compression stroke length of the elastic component for retraction, and F represents the working force of the wedge mechanism for stamping dies.

[0064] The length N of the wedge mechanism for stamping dies is the dimension from the front end to the rear end of the wedge base. When the tool mounting surface 3e is the front surface, the width W of the wedge mechanism for stamping dies is the dimension from one side of the wedge slider 3 to the other when the working surface 3e is the front side. The closing height H of the wedge mechanism for stamping dies is the dimension from the upper surface of the wedge base to the lower surface of the wedge driver.

[0065] like Figure 3 The diagram shown is a schematic of a wedge mechanism for stamping dies when the machining angle is less than 50°. Figure 4 The diagram shows a wedge mechanism for a stamping die with a machining angle greater than or equal to 50°. θ1 is the angle between the force direction and the horizontal direction when the wedge mechanism is working, representing the machining angle at which the wedge mechanism performs its work. θ2 is the angle between the wedge and the horizontal direction, determined based on the machining angle θ1. L is the stamping stroke. S is the working stroke. S' is the spring stroke, determined based on the working stroke of the wedge mechanism.

[0066] Stamping die designers select the wedge mechanism for processing panels based on factors such as the panel thickness and tensile strength. The selection of the wedge mechanism is based on its working force, stroke, and processing angle. When selecting, it is according to... Figure 3 or Figure 4 The schematic diagram of the wedge shown indicates the selection of a wedge mechanism. The length, width, and height of the wedge mechanism are used to determine the wedge mechanism that meets the installation requirements.

[0067] When the wedge mechanism of the stamping die is working, it will convert the vertical die pressure P into the working force F of the wedge mechanism. The angle between the direction of the working force F and the horizontal direction is the processing angle θ1 when the wedge mechanism of the stamping die is working. The angle between the direction of the motion trajectory of the first sliding part of the wedge mechanism and the horizontal direction is θ2. θ2 represents the angle between the wedge and the horizontal direction. The angle θ2 between the wedge and the horizontal direction is determined according to the relationship between the working force of the wedge mechanism and the angle θ1 of the horizontal direction.

[0068] The magnitude of the force and applied force, the working angle, and the motion trajectory of the first and second sliding parts of the wedge mechanism used in stamping dies conform to the following: Figure 3 The triangular relationship shown.

[0069] The basic formulas for the relationship between the die pressure P, the working force F, the machining angle θ1, and the angle θ2 between the wedge and the horizontal direction in a stamping die are as follows:

[0070] ・・・ (2)

[0071] In the actual design process of the wedge mechanism for stamping dies, F and θ1 are known quantities determined by the working requirements parameters, and P is determined by multiplying the known pressure of the stamping die by the mounting surface area A of the wedge mechanism for stamping dies; the relationship between θ2 and P, F, and θ1 can be expressed by the following formula:

[0072] ・・・ (3)

[0073] Based on the above formula, the innovation of this utility model lies in optimizing the value of θ2 and updating the calculation formulas of V, Q, S, S´, and L. Based on the new calculation formulas, the various parameters of the wedge mechanism for stamping dies are calculated and redefined.

[0074] V: The load applied to the second planar sliding surface of the wedge mechanism.

[0075] ・・・ (4)

[0076] Q: The load applied to the second V-shaped sliding surface of the wedge mechanism.

[0077] ・・・ (5)

[0078] L: The stamping stroke of the wedge mechanism for stamping dies is the height difference between the height at the moment when the first V-shaped sliding surface and the second V-shaped sliding surface begin to contact and the lowest height during operation. In die design, the stamping stroke L of the wedge mechanism for stamping dies is determined by the working requirement parameters.

[0079] S: The length of the path the slider travels forward along the direction of the applied force during operation, i.e., the working stroke.

[0080] ・・・ (6)

[0081] S´: The compression stroke length of the elastic component used for retraction, i.e., the spring stroke.

[0082] ・・・ (7)

[0083] Typically, wedge mechanisms require a larger sliding area to increase their working force. While increasing the sliding area can generate a higher working force, the wedge mechanism itself also becomes larger. Here, the size of the wedge mechanism refers to its width, closing height, and length.

[0084] The size of the wedge mechanism depends on the size of the wedge slider. Once the size of the wedge slider is determined, the sizes of the wedge driver and the wedge base can also be determined, thus determining the width, closed height, and length of the entire wedge mechanism.

[0085] The size of the wedge slider is determined by the spring. When the working force of the wedge mechanism is determined, the return force is also determined; when the return force is determined, the diameter and length of the spring corresponding to the return force can also be determined; once the diameter and length of the spring are determined, the size of the corresponding wedge slider is determined.

[0086] To balance the optimal working force and dimensions of the wedge mechanism, the wedge mechanism of this invention quantifies the range of working force, width, height, and length.
