Description

Technical Field

[0001] This utility model relates to the field of shearing dies, and more specifically, to a compatible blanking shearing die. Background Technology

[0002] The blanking and shearing die for automotive molds is a key component in the stamping process. It is mainly used to cut metal sheets (such as steel sheets, aluminum sheets, etc.) into blanks of specific shapes according to design requirements, providing accurate blanks for subsequent forming processes.

[0003] By setting a horizontal distance between the upper and lower die cutters, the shearing process is advanced gradually from one side of the material to the other, rather than being a sudden cut. This disperses the shearing force, reduces impact load, and protects the cutting tools and machine tool. This horizontal distance directly affects the shearing angle (blade tilt angle). A larger horizontal distance increases the shearing angle, allowing the material to be sheared in stages, suitable for thick materials; a smaller distance is suitable for thin materials, ensuring a clean cut. Therefore, the horizontal distance between the upper and lower die cutters needs to be set to different values ​​depending on the size, thickness, and material of the material being sheared.

[0004] Currently, in order to adapt to the different requirements of materials for the horizontal spacing between the upper and lower dies, different parts require the development of a corresponding blanking and shearing die, which results in very high die development costs. Utility Model Content

[0005] The purpose of this invention is to provide a compatible blanking and shearing die. This compatible blanking and shearing die can adjust the horizontal distance between the upper and lower die blades by changing different shims, thereby achieving compatibility with the production of different sheet materials and greatly reducing the cost of die development.

[0006] To achieve the above objectives, this utility model provides a compatible blanking and shearing die, including an upper die, a lower die, an upper die cutter connected to the upper die, a lower die cutter connected to the lower die, and a shim. The shim is detachably connected to the lower die and is used to adjust the distance between the upper die cutter and the lower die cutter.

[0007] The lower mold is also equipped with a push-pull rod. The telescopic end of the push-pull rod is connected to the lower mold cutter and pushes the lower mold cutter closer to or away from the shim. There are multiple shims, and the thickness of different shims is set differently.

[0008] Preferably, the lower die includes a blanking area, the blanking area includes a blanking slide and a first support member for supporting the blanking slide, and a detachable second support member is provided between the first support member and the lower die cutter.

[0009] Preferably, the lower die further includes a lower die cutter mounting position and an auxiliary material support area. The lower die cutter and the lower die cutter mounting position are detachably connected by fasteners, and the gasket is detachably connected to the auxiliary material support area.

[0010] Preferably, the lower die mounting position is provided with a waist-shaped hole that mates with a fastener.

[0011] Preferably, the lower die holder mounting position is provided with a first guide, and the lower die holder is provided with a second guide that cooperates with the first guide. Through the cooperation of the first guide and the second guide, the lower die holder slides relative to the lower die holder mounting position.

[0012] Preferably, the compatible blanking and shearing die further includes a pressure plate, which is connected to the upper die by an elastic compressible element.

[0013] Preferably, the auxiliary material support area includes a floating guide and a material support block, and the height of the driving surface of the floating guide is adjustable.

[0014] According to the above technical solution, the upper die cutter of this utility model is connected to the upper die, and the upper die drives the upper die cutter to rise and fall. When the upper die cutter falls to the same height as the lower die cutter, it will start to shear the sheet material.

[0015] By setting a horizontal gap between the upper and lower die cutters, the shearing process progresses gradually from one side of the material to the other, rather than cutting it off instantly. This disperses the shearing force, reduces impact load, and protects the cutting tools and machine tools. Since the horizontal gap between the upper and lower die cutters needs to be set differently depending on the size, thickness, and material of the material, different thicknesses of shims are required for different sheet metal production. Therefore, multiple shims of varying thicknesses are set according to actual production needs, with different shims corresponding to different sheet metals. When shearing different sheet metals, the horizontal gap between the upper and lower die cutters can be adjusted by changing different shims.

[0016] The horizontal distance between the upper and lower die cutters is very small, so the thickness of the shim is usually not set to be equal to this horizontal distance.

[0017] The upper die cutter is fixedly connected to the upper die. During the descent of the upper die, the relative positions of the upper and lower dies remain unchanged; that is, the relative positions of the upper die cutter and the lower die in the horizontal direction are fixed. In one embodiment, a shim is disposed on the side of the lower die cutter near the upper die cutter. The lower die has a machined surface for fixing the shim, and the relative position of this machined surface with the lower die is fixed. Therefore, the relative position of this machined surface with the upper die cutter in the horizontal direction is fixed. The lower die cutter is positioned after abutting against the shim. By changing shims of different thicknesses, the relative positions of the upper and lower die cutters can be adjusted. When the thickness of the shim increases, the horizontal distance between the upper and lower die cutters increases; when the thickness of the shim decreases, the horizontal distance between the upper and lower die cutters decreases.

[0018] Before each switch to process a material, a suitable shim is selected and fixed to the processing surface according to the distance between the upper and lower die cutters corresponding to that material. Then, the lower die cutter is pushed against the shim by the push rod, and then the position of the lower die cutter is locked. In this way, the horizontal distance between the upper and lower die cutters can be guaranteed.

[0019] In another embodiment, a shim is disposed on the side of the lower die cutter away from the upper die cutter. The lower die has a machined surface for fixing the shim, and the relative position of this machined surface with respect to the lower die is fixed, thus the horizontal distance between the machined surface and the upper die cutter is fixed. The lower die cutter is positioned after abutting against the shim. By replacing shims of different thicknesses, the relative position of the upper and lower die cutters can be adjusted. Increasing the thickness of the shim decreases the horizontal relative distance between the upper and lower die cutters, and decreasing the thickness of the shim increases the horizontal relative distance between the upper and lower die cutters.

[0020] In summary, when using this blanking and shearing die, the horizontal distance between the upper and lower die blades can be adjusted by changing different shims, thereby achieving compatibility with the production of different sheet materials and greatly reducing the cost of die development.

[0046] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0047] In this utility model, unless otherwise stated, directional words such as "between" and "not less than" contained in the terminology only represent the orientation of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0048] A compatible blanking and shearing die includes an upper die 1, a lower die 2, an upper die cutter 11 connected to the upper die 1, a lower die cutter 21 connected to the lower die 2, and a shim 3. The shim 3 is detachably connected to the lower die 2 and is used to adjust the distance between the upper die cutter 11 and the lower die cutter 21.

[0049] The lower mold 2 is also provided with a push-pull rod 4. The telescopic end of the push-pull rod 4 is connected to the lower mold cutter 21 and pushes the lower mold cutter 21 closer to or away from the gasket 3. There are multiple gaskets 3, and the thickness of different gaskets 3 is set to be different.

[0050] Through the implementation of the above technical solution, the upper die cutter 11 is connected to the upper die 1, and the upper die 1 drives the upper die cutter 11 to rise and fall. When the upper die cutter 11 falls to the same height as the lower die cutter 21, it will start to shear the plate.

[0051] By setting a horizontal gap between the upper die cutter 11 and the lower die cutter 21, the shearing process progresses gradually from one side of the material to the other, rather than cutting it off instantly. This disperses the shearing force, reduces impact load, and protects the cutting tools and machine tools. Since the horizontal gap between the upper die cutter 11 and the lower die cutter 21 needs to be set to different values ​​for materials of different sizes, thicknesses, and materials, different thicknesses of shims 3 are required for different sheet metal production. Therefore, multiple shims 3 are set to different thicknesses according to actual production needs, with different shims 3 corresponding to different sheet metals. When different sheet metals need to be sheared, the horizontal gap between the upper die cutter 11 and the lower die cutter 21 can be adjusted by changing different shims 3.

[0052] The horizontal distance between the upper die cutter 11 and the lower die cutter 21 is very small, so the thickness of the shim 3 is usually not set to be equal to this horizontal distance.

[0053] The upper die cutter 11 is fixedly connected to the upper die 1. During the lifting and lowering of the upper die 1, the relative position of the upper die 1 and the lower die 2 remains unchanged; that is, the relative position of the upper die cutter 11 and the lower die 1 in the horizontal direction is fixed. In one embodiment, a shim 3 is disposed on the side of the lower die cutter 21 near the upper die cutter 11. The lower die 2 is provided with a machining surface for fixing the shim 3. The relative position of this machining surface with the lower die 1 is fixed, therefore the relative position of this machining surface with the upper die cutter 11 in the horizontal direction is fixed. The lower die cutter 21 is positioned after abutting against the shim 3. By replacing the shims 3 with different thicknesses, the relative position of the upper die cutter 11 and the lower die cutter 21 can be adjusted. When the thickness of the shim 3 increases, the horizontal distance between the upper die cutter 11 and the lower die cutter 21 increases; when the thickness of the shim 3 decreases, the horizontal distance between the upper die cutter 11 and the lower die cutter 21 decreases.

[0054] Before each switch to process a material, a suitable shim 3 is selected and fixed to the processing surface according to the distance between the upper die 11 and the lower die 21 corresponding to the material. Then, the lower die 21 is pushed against the shim 3 by the push rod, and then the position of the lower die 21 is locked. In this way, the horizontal distance between the upper die 11 and the lower die 21 can be guaranteed.

[0055] In another embodiment, the shim 3 is disposed on the side of the lower die cutter 21 away from the upper die cutter 11. The lower die 2 is provided with a machined surface for fixing the shim 3. The relative position of this machined surface with the lower die 1 is fixed, so the horizontal distance between the machined surface and the upper die cutter 11 is fixed. The lower die cutter 21 is positioned after abutting against the shim 3. By replacing the shim 3 with shims of different thicknesses, the relative position of the upper die cutter 11 and the lower die cutter 21 can be adjusted. When the thickness of the shim 3 increases, the horizontal relative distance between the upper die cutter 11 and the lower die cutter 21 decreases; when the thickness of the shim 3 decreases, the horizontal relative distance between the upper die cutter 11 and the lower die cutter 21 increases.

[0056] In summary, when using this blanking and shearing die, the horizontal distance between the upper die cutter 11 and the lower die cutter 21 can be adjusted by changing different shims 3, thereby achieving production compatibility for different sheet materials and greatly reducing the cost of die development.

[0057] In this embodiment, preferably, the lower die 2 includes a material feeding area, which includes a material feeding slide 22 and a first support member for supporting the material feeding slide 22. A detachable second support member (24) is provided between the first support member and the lower die cutter 21.

[0058] The sheet metal cut by the blanking shearing die is collected in the blanking area and falls into the blanking slide 22, then along the slide into the workpiece collection area. A first support member is positioned facing the lower die cutter 21 to support the blanking slide. Because the distance between the blanking slide and the lower die cutter 21 is small, the limited operating space for installing the lower die cutter 21 makes its installation inconvenient.

[0059] The detachable second support 24 provides space for the lower die cutter 21 to be installed. When the lower die cutter 21 needs to be installed, the second support 24 can be removed or not installed first, thereby providing more space on the lower die 2 for placing the lower die cutter 21, which facilitates the installation of the lower die cutter 21.

[0060] When the shim 3 needs to be replaced, the second support (24) needs to be installed in place. The second support (24) is located in front of the lower die cutter 21 and is used to limit the stroke of the lower die cutter 21. The push-pull rod 4 is located behind the lower die cutter 21, and the telescopic rod of the push-pull rod 4 is connected to the lower die cutter 21. When the shim 3 needs to be replaced, first remove the fastener 26 connecting the lower die cutter 21 and the lower die 2, so that the lower die cutter 21 and the lower die 2 can slide relative to each other. Then, extend the telescopic rod of the push-pull rod 4 forward to pull the lower die cutter 21 forward. The shim 3 is located on the side of the lower die cutter 21 near the push-pull rod 4. After the push-pull rod 4 retracts the lower die cutter 21, the gap between the shim 3 and the lower die cutter 21 increases, allowing the operator to remove the shim 3 in use and replace it with a new one. After the new shim 3 is placed, the push-pull rod 4 is pulled back, and the lower die cutter 21 moves backward until it abuts against the shim 3 and presses it tightly. At this point, the fastener 26 between the lower die cutter 21 and the lower die 2 is tightened again, which locks the position of the lower die cutter 21, thereby adjusting the horizontal distance between the upper die cutter 11 and the lower die cutter 21.

[0061] By setting the second support member (24) in front of the lower die cutter 21, the stroke of the lower die cutter 21 can be limited, so that the lower die cutter 21 can only leave the pad 3 by a small distance. That is, there is only a small gap between the lower die cutter 21 and the mounting surface of the pad 3, making it easier for the pad 3 to enter the space vertically when it is placed. When the lower die cutter 21 moves backward, it can easily press the pad 3 onto the mounting surface of the pad 3.

[0062] The gasket 3 is provided with a U-shaped hole. The side of the auxiliary material support area facing the downward die 21 is provided with a first positioning surface. The first positioning surface is provided with a support member that mates with the U-shaped hole. The upper part of the support member is provided with a curved surface that mates with the bottom of the U-shaped hole. After the U-shaped hole is inverted and placed on the support member, the gasket 3 can be initially fixed.

[0063] Preferably, to avoid interference between the support and the lower die 21, the thickness of the support must be less than the thickness of the thinnest shim 3. Therefore, the support cannot provide a stable support effect to the shim 3, resulting in an unstable state when the shim 3 and the support are in contact. Since the horizontal distance between the upper die 11 and the lower die 21 is small during production, the thickness difference between different shims 3 is not significant. By setting a second support (24), the lower die 21 is limited to being pushed out only a small distance, approximately equal to the thickness of the shim 3, ensuring that the shim 3 does not fall off the support when it is replaced, thereby improving the reliability of the shim 3 replacement process.

[0064] In this embodiment, preferably, the lower mold 2 further includes a lower mold cutter mounting position 25 and an auxiliary material support area. The lower mold cutter 21 is detachably connected to the lower mold cutter mounting position 25 by fasteners 26, and the gasket 3 is detachably connected to the auxiliary material support area.

[0065] The material feeding area and the auxiliary material support area are located on both sides of the lower die cutter 21. The shim 3 is set on the side of the lower die cutter 21 closer to the auxiliary material support area. By replacing the shim 3 with a thicker one, the lower die cutter 21 can be pushed closer to the upper die cutter 11, thereby reducing the horizontal distance between the upper die cutter 11 and the lower die cutter 21. Conversely, by replacing the shim 3 with a thinner one, the lower die cutter 21 can be pulled away from the upper die cutter 11, thereby increasing the horizontal distance between the upper die cutter 11 and the lower die cutter 21.

[0066] The upper die cutter 11 is fixedly connected to the upper die 1, and the auxiliary material support area is fixedly set on the lower die 2 body. The relative position between the upper die 1 and the lower die 2 remains fixed. The auxiliary material support area is provided with a mounting surface for mounting the shim 3. The distance between the mounting surface and the upper die cutter 11 remains fixed. Therefore, the horizontal distance between the upper die cutter 11 and the lower die cutter 21 can be adjusted by adjusting the thickness of the shim 3 between the mounting surface and the lower die cutter 21.

[0067] The lower die cutter 21 is fixed to the lower die cutter mounting position 25 by fastener 26. By removing the fastener 26, the lower die cutter 21 can be separated from the lower die cutter mounting position 25. After removing the fastener 26, the push-pull rod 4 can push the lower die cutter 21 to slide relative to the lower die cutter mounting position 25, thereby releasing the gasket 3, making it convenient to remove the gasket 3 in use and replace it with a new gasket 3.

[0068] The auxiliary material support area has a storage location for the gasket 3, and the gasket 3 is marked to confirm its usage scenario. A screw is provided in the auxiliary material support area, and the gasket 3 has a U-shaped hole that mates with the screw. By mates the U-shaped hole of the gasket 3 with the screw, some degrees of freedom of the gasket 3 can be restricted. Preferably, a fastening nut 52 can also be installed to tighten the gasket 3 onto the screw.

[0069] Preferably, during the production process, multiple gaskets 3 of the same type need to be used simultaneously. These gaskets 3 are evenly distributed along the length of the lower die cutter 21, and different screws are used to house them at different positions. Each screw holds a set of gaskets 3, and the number and type of gaskets 3 are the same on different screws. A set of gaskets 3 includes all the required thicknesses of gaskets 3 for the blanking and shearing die, ensuring compatible production for all types of sheet metal.

[0070] More preferably, each gasket 3 is marked with a label indicating the type of sheet material it corresponds to, which allows operators to quickly replace the gasket 3 during the production process.

[0071] In this embodiment, preferably, the lower die mounting position 25 is provided with an oblong hole that mates with the fastener 26.

[0072] By engaging with the oblong hole at different positions, the fastener 26 can fix the lower die cutter 21 at different positions on the lower die 2, thereby controlling the different horizontal distances between the lower die cutter 21 and the upper die cutter 11.

[0073] In this embodiment, preferably, the lower die mounting position 25 is provided with a first guide 28, and the lower die 21 is provided with a second guide 211 that cooperates with the first guide 28. Through the cooperation of the first guide 28 and the second guide 211, the lower die 21 can slide relative to the lower die mounting position 25.

[0074] Through the cooperation of the first guide 28 and the second guide 211, when the push-pull rod 4 acts on the lower die cutter 21, the lower die cutter 21 can move back and forth in a straight line, thereby ensuring the reliability of the position of the lower die cutter 21 during use.

[0075] Preferably, the cross-section of the first guide 28 is set as a triangular protrusion, and the second guide 211 is provided with a triangular groove that cooperates with the triangular protrusion. This cooperation method can restrict the lower die cutter 21 to move along a straight line.

[0076] In this embodiment, preferably, the compatible blanking and shearing die further includes a pressure plate 12, which is connected to the upper die 1 by an elastic compressible member 13.

[0077] When the upper die 11 descends to the same height as the lower die 21, the upper die 1 continues to descend, and the relative movement between the upper die 11 and the lower die 21 can achieve the shearing effect on the sheet material.

[0078] The pressure plate 12 is connected to the upper mold 1 and moves downward together with it. After contacting the material, the pressure plate 12 presses the material into the auxiliary support area. As the upper mold 1 continues to move, the elastic compressible member 13 is compressed and applies pressure to the material below through the pressure plate 12, keeping the material relatively stationary with respect to the lower mold 2. At the position where the pressure plate 12 is pressed against the lower mold cutter 21, the material cannot be displaced under the action of the pressure plate 12.

[0079] The lower die cutter 21 is equipped with a cutting edge. When the upper die cutter 11 contacts the sheet material, it pushes the sheet material at that position downward. Since the pressure plate 12 presses the sheet material above the lower die cutter 21, the sheet material on the lower die cutter 21 cannot move. Therefore, under the action of the upper die cutter 11, the sheet material will first bend along the cutting edge of the lower die cutter 21. At the same time, the material is locally compressed and undergoes elastic deformation. At this time, it has not yet been cut. As the upper die cutter 11 continues to descend, the pressure exceeds the yield strength of the material, and the cutting edge cuts into the sheet material. The sheet material generates micro-cracks at the cutting edge position of the lower die cutter 21 due to stress concentration. The cracks continue to expand and eventually separate, thus completing the shearing.

[0080] During the shearing process of the sheet material, the pressure plate 12 fixes the sheet material in place, thereby achieving reliable shearing of the sheet material.

[0081] In this embodiment, preferably, the auxiliary material support area includes a floating guide 291 and a material support block 292, and the height of the driving surface of the floating guide 291 is adjustable.

[0082] During the production process, the roller 61 of the floating feeder 291 rotates continuously to achieve the purpose of conveying the sheet material. When the sheet material is conveyed to the position, the roller 61 will stop rotating. Then the upper die 1 descends to start shearing the sheet material. When the pressure plate 12 is pressed down, the pressure plate 12 will first contact the roller 61 through the sheet material. At this time, the upper die cutter 11 has not yet moved to the height of the lower die cutter 21 and cannot cut the sheet material.

[0083] As the upper die 1 continues to descend, the pressure plate 12 presses down the roller 61 until the roller 61 descends to the same height as the material support block 292. At this time, the pressure plate 12 presses the sheet material onto the material support block 292 and the lower die cutter 21. The upper die cutter 11 descends to the height of the lower die cutter 21. Then the upper die continues to descend, and the sheet material on the lower die cutter 21 is pressed by the pressure plate 12. The upper die cutter 11 begins to apply pressure to the sheet material, causing the sheet material to deform around the blade of the lower die cutter 21 and eventually be sheared.

[0084] A spring 62 is installed under the rotating shaft of the floating feeder 291. When the pressure plate 12 contacts the plate, the spring 62 is compressed under the action of the pressure plate 12, and the roller 61 descends. During the process, the pressure applied by the pressure plate 12 to the plate is consistent with the elastic force of the spring 62. Subsequently, the plate contacts the support block 292, and the pressure block 12 no longer descends with the upper die. At this time, the force of the pressure block 12 on the plate is consistent with the elastic force of the elastic compressible member 13.

[0085] When the shearing operation is completed, the upper die 1 rises, the pressure plate 12 rises, and the roller 61 rises under the action of the spring 62 to return to the working state.

[0086] A method for using a compatible blanking and shearing die, comprising:

[0087] Step 1: Disassemble the second support component (24) and install the lower die cutter 21;

[0088] Step 2: Install the second support component (24);

[0089] Step 3: When it is necessary to replace gasket 3, remove fastener 26;

[0090] Step 4: The push-pull rod 4 separates the lower die cutter 21 from the gasket 3, and replaces the gasket 3 with a new one;

[0091] Step 5: The push-pull rod 4 moves in the reverse direction, and the lower die cutter 21 presses the gasket 3 into the auxiliary material support area;

[0092] Step 6: Install fastener 26 to fix the lower die cutter 21 to the lower die cutter mounting position 25.

[0093] First, the lower die cutter 21 needs to be installed. By disassembling the second support member (24), a larger space can be obtained on the lower die 2 for installing the lower die cutter 21. When installing the lower die cutter 21, the shim 3 of the corresponding sheet material also needs to be placed in place.

[0094] After the lower die cutter 21 is installed, the second support (24) needs to be installed in place. The second support (24) is used to limit the stroke of the lower die cutter 21 to prevent the lower die cutter 21 from being pushed out a large distance under the action of the push-pull rod 4. This makes the distance between the lower die cutter 21 and the first positioning surface approximately equal to the thickness of the shim 3. When the shim 3 is replaced, the shim 3 is less likely to slip off the support, making the process of replacing the shim 3 more reliable.

[0095] When it is necessary to replace the shim 3, the fastener 26 can be removed first, allowing the lower die cutter 21 and the lower die 2 to slide relative to each other. Then, by pushing the push-pull rod 4, the lower die cutter 21 is pushed forward, releasing the shim 3 in use. The operator can then remove the shim 3 in use and replace it with a new shim 3. Afterward, the lower die cutter 21 is pulled back by the push-pull rod 4 and placed against the shim 3, thus adjusting the horizontal distance between the upper die cutter 11 and the lower die cutter 21. This allows the blanking and shearing die to meet the production requirements of the new sheet metal.

[0096] In this embodiment, preferably, in step one, the auxiliary material support area is provided with a first positioning surface that is fixedly connected to the lower mold 2, and the lower mold blade 21 presses the pad 3 against the first positioning surface.

[0097] The first positioning surface needs to be precision machined to ensure the relative position between the first positioning surface and the lower mold 2. A guide structure 7 is provided between the upper mold 1 and the lower mold 2. The guide structure 7 can ensure the relative position between the upper mold 1 and the lower mold 2. The upper mold cutter 11 is fixedly connected to the upper mold 1, thereby ensuring the relative position between the first positioning surface and the upper mold cutter 11. That is, the distance between the upper mold cutter 11 and the first positioning surface is fixed. Therefore, by adjusting the thickness of the shim 3 and pressing the lower mold cutter 21 against the shim 3, the horizontal distance between the lower mold cutter 21 and the upper mold cutter 11 can be adjusted.

[0098] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings.
