Description

Technical Field

[0001] This application relates to the field of stamping die technology, and in particular to a full-circumferential swing cutting die. Background Technology

[0002] Products with full-circumference flanged curved cross-sections require high dimensional accuracy in height. Therefore, after flange forming, a side-cutting die is used to punch the entire circumference of the product to ensure the required height. Traditional side-cutting processes involve two stages, requiring two sets of dies to perform transverse and longitudinal side-cuts on the flanged product to achieve full-circumference side-cutting and obtain the full-circumference flanged curved cross-section.

[0003] Due to positioning errors during the replacement of the side-cutting mold, the product's cross-section is not cut evenly, resulting in height differences in the curved cross-section, which affects the product's quality and appearance. Summary of the Invention

[0004] This application provides a full-circumferential swing cutting die to solve the technical problem in the prior art where positioning errors during the replacement of side cutting dies result in uneven product cross-sections and height differences in the product's arc-shaped cross-sections, affecting product quality and appearance.

[0005] In a first aspect, this application provides a circumferential swing-cutting die, comprising: a base, having at least one pair of first guide rails and one pair of second guide rails, the first guide rails being disposed opposite each other in a first horizontal direction, the second guide rails being disposed opposite each other in a second horizontal direction, the first and second horizontal directions intersecting; a bracket, slidably disposed on the first and second guide rails in a vertical direction, the bracket including a first platform and a second platform disposed opposite each other, the second platform being located between the first platform and the base; a slide block, disposed on the side of the second platform facing the first platform, the slide block having a slider and a positioning element disposed on the side of the slide block facing the first platform, the slider being oscillatingly connected to the first or second guide rails, the slider having a first receiving cavity, the positioning element being disposed in the first receiving cavity for positioning the product; a first cutter, disposed on the side of the first platform facing the second platform; and a second cutter, disposed in the first receiving cavity of the slider; wherein, when the first platform is subjected to force and moves towards the base, the slider drives the second cutter to reciprocate in the first or second horizontal direction to cut the arc-shaped cross-section of the product.

[0011] In one possible implementation, a first connecting hole is provided at the center of the slide, and a second connecting hole corresponding to the first connecting hole is provided on the connecting block and the positioning member. A first fastener is provided in both the first connecting hole and the second connecting hole.

[0012] In one possible implementation, a reset member is provided on the second inner ejector plate, with one end of the reset member connected to the second inner ejector plate and the other end connected to the limit block, so that the second cutter can be reset after swinging.

[0013] In one possible implementation, the reset member includes a base, an elastic body, and a guide post. One end of the elastic body is connected to the base, and the other end is connected to the guide post. The second inner release plate has a third accommodating cavity in the vertical direction, and the base and the elastic body are embedded in the third accommodating cavity of the second inner release plate. The limiting block has a first step and a second step connected to each other. The first step of the limiting block abuts against the second inner release plate, and the first step is provided with a conical groove that is slidably connected to the guide post. The second step of the limiting block is engaged with the connecting block.

[0014] In one possible implementation, a first cutter holder is also included. The first cutter holder is disposed on a first platform, and the side of the first cutter holder facing away from the first platform abuts against the slider. A first cutter is embedded in the first cutter holder. A first cavity is provided on the side of the first cutter holder facing the slider, and a second cavity corresponding to the first cavity is provided on the side of the slider facing the first cutter holder. A recycling space for accommodating punching waste is formed between the first cavity and the second cavity.

[0015] In one possible implementation, a first inner stripper is provided inside the first cutter, with one side of the first inner stripper connected to the first platform and the other side abutting against the product housing.

[0016] In one possible implementation, a first through hole is provided on the second platform for the passage of the first guide rail, and a second through hole is provided on the second platform for the passage of the second guide rail.

[0017] In one possible implementation, the first cutter has a first cutting edge on the side facing the positioning member, and the first cutting edge of the first cutter is inclined at an angle relative to the horizontal plane. The second cutter has a second cutting edge on the side facing the first cutter. The orthographic projection of the first cutting edge of the first cutter on the second platform covers the orthographic projection of the second cutting edge of the second cutter on the second platform.

[0018] In one possible implementation, the orthographic projection of the second cutting edge of the second cutter onto the vertical plane is a first arc-shaped curve, and the orthographic projection of the first arc-shaped surface of the slide onto the vertical plane is a second arc-shaped curve, wherein the radius of curvature of the first arc-shaped curve is equal to the radius of curvature of the second arc-shaped curve.

[0019] In one possible implementation, a first groove is provided on the first cutting edge of the first cutter, a first protrusion corresponding to the first groove is provided on the second cutting edge of the second cutter, and a through groove corresponding to the first protrusion is provided on the positioning member.

[0020] The technical solutions provided in this application have the following advantages compared with the prior art:

[0021] The circumferential swing-cutting die provided in this application embodiment, before operation, places the flanged product on the positioning member. The flange of the shell covers the periphery of the positioning member. After the first platform and the second platform close together, the first cutter and the second cutter close in the vertical direction to form a shearing area. This shearing area corresponds to the arc-shaped contour of the product that needs to be punched. Then, the first platform is driven by force to move the first cutter towards the base. Since the slider is oscillatingly connected to the first guide rail, the first guide rail applies an inclined extrusion force to the slider. Under the action of the pressure, the slider drives the second cutter to swing back and forth relative to the slide in the first horizontal direction. Under the action of the shearing force between the first cutter and the second cutter, the arc-shaped cross-section of the product in the first horizontal direction is punched out. Similarly, the first platform continues to move towards the base. Since the slider is oscillatingly connected to the second guide rail, the second guide rail applies an inclined extrusion force to the slider, causing the slider to drive the second cutter to swing back and forth relative to the slide in the second horizontal direction. Under the action of the shearing force between the first cutter and the second cutter, the arc-shaped cross-section of the product in the second horizontal direction is punched out. At this point, the punching of the product's full-circumference arc-shaped cross-section can be completed. Since there is no need to change the side-cutting die, the entire punching process is positioned by the positioning component, avoiding the positioning errors caused by changing the side-cutting die. This ensures that the arc-shaped cross-section of the product is flush, improving the product's quality and appearance, while also increasing side-cutting efficiency and reducing die costs.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0040] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0041] Products with full-circumference flanged curved cross-sections require high dimensional accuracy in height. Therefore, after flange forming, a side-cutting die is used to punch out the entire circumference of the product to ensure the required height. Traditional side-cutting processes involve two stages, requiring two sets of side-cutting dies. Figure 1 and Figure 2 As shown, the product after flanging is side-cut both laterally and longitudinally to achieve full-circumference side punching and obtain the arc-shaped cross-section of the full-circumference flanged edge. Figure 3As shown, the product 200 includes a housing 201, with flanges 202 around its perimeter. The flanges 202 have an arc-shaped cross-section 203 on the side facing away from the housing 201, and a notch 204 can be provided on the arc-shaped cross-section 203 according to functional requirements. Due to positioning errors during the replacement of the side-cutting mold, the cross-section of the product 200 is not cut evenly, such as... Figure 4 As shown, the arc-shaped cross-section 203 of product 200 has a height difference, which affects the quality and appearance of product 200.

[0042] To address the technical problem in the prior art where positioning errors during the replacement of the side-cutting mold result in uneven cuts on the cross-section of product 200 and height differences on the arc-shaped cross-section 203 of product 200, affecting the quality and appearance of product 200, this application provides a full-circumferential swing-cutting mold 100. This mold ensures that the arc-shaped cross-section 203 of product 200 is flush, improving the quality and appearance of product 200, while also increasing side-cutting efficiency and reducing mold costs.

[0043] Figure 5 and Figure 6 A full-circumferential swivel cutting die 100 provided in this application embodiment includes a base 1, a support 2, a slide 3, a first cutter 4, and a second cutter 5. The base 1 is provided with at least a pair of first guide rails 11 and a pair of second guide rails 12. The first guide rails 11 are arranged opposite each other in a first horizontal direction, and the second guide rails 12 are arranged opposite each other in a second horizontal direction. The first and second horizontal directions intersect. The support 2 is slidably disposed on the first guide rails 11 and the second guide rails 12 in a vertical direction. The support 2 includes a first platform 21 and a second platform 22 arranged opposite each other. The second platform 22 is located between the first platform 21 and the base 1. The slide 3 is disposed on the second platform 22 facing the first platform 21. On one side, a slider 31 and a positioning element 32 are provided on the side of the slide block 3 facing the first platform 21. The slider 31 is oscillatingly connected to the first guide rail 11 or the second guide rail 12. The slider 31 has a first receiving cavity 311. The positioning element 32 is disposed in the first receiving cavity 311 for positioning the product 200. The first cutter 4 is disposed on the side of the first platform 21 facing the second platform 22. The second cutter 5 is disposed in the first receiving cavity 311 of the slider 31. When the first platform 21 is subjected to force and moves towards the base 1, the slider 31 drives the second cutter 5 to oscillate back and forth in the first horizontal direction or the second horizontal direction to punch the arc-shaped cross-section 203 of the product 200.

[0044] For ease of understanding and explanation, the first horizontal direction is the X-axis shown in the figure, the second horizontal direction is the Y-axis shown in the figure, and the vertical direction is the Z-axis shown in the figure. It can be understood that an external punching device (e.g., a punch press) can be installed on the side of the first platform 21 facing away from the second platform 22. The external punching device can apply a vertically downward external force F1 to the first platform 21, causing the support 2 as a whole to move closer to the base 1. Before operation, the product 200 after the flange 202 is formed is placed on the positioning member 32. The flange 202 of the housing 201 covers the periphery of the positioning member 32. After the first platform 21 and the second platform 22 are closed, the first cutter 4 and the second cutter 5 close in the vertical direction (Z-direction) to form a shearing area. This shearing area corresponds to the arc-shaped contour of the product 200 that needs to be punched. Then, as... Figure 7 As shown, the first platform 21 is driven by force to move the first cutter 4 towards the base 1. Since the slider 31 is oscillatingly connected to the first guide rail 11, the first guide rail 11 applies an inclined compressive force to the slider 31. Under this pressure, the slider 31 drives the second cutter 5 to oscillate reciprocally relative to the slide block 3 in the X direction. Under the shearing force between the first cutter 4 and the second cutter 5, the arc-shaped cross-section 203 of the product 200 in the X direction is punched out. Similarly, the first platform 21 continues to move towards the base 1 under force, as... Figure 8 As shown, since the slider 31 is oscillatingly connected to the second guide rail 12, the second guide rail 12 applies an inclined compressive force F2 to the slider 31, causing the slider 31 to drive the second cutter 5 to oscillate back and forth relative to the slide block 3 in the Y direction. Under the shearing force between the first cutter 4 and the second cutter 5, the arc-shaped cross-section 203 of the product 200 in the Y direction is punched out. Thus, the punching of the arc-shaped cross-section 203 of the product 200 in the entire circumference can be completed. Since there is no need to change the side-cutting die, the entire punching process is positioned by the positioning component 32, avoiding the positioning error caused by changing the side-cutting die. This ensures that the arc-shaped cross-section 203 of the product 200 is flush, improving the quality and appearance of the product 200, while also increasing side-cutting efficiency and reducing die costs.

[0045] It should be noted that in this embodiment of the application, four first guide rails 11 are provided, and the four first guide rails 11 are respectively provided at the four corners of the first platform 21 to improve the smoothness of the movement of the first platform 21, thereby ensuring the quality of the finished product 200 cut by the first cutter 4.

[0046] like Figure 9As shown, the slide block 3 has a first arc-shaped surface 301 on the side facing the first platform 21, and the slider 31 has a second arc-shaped surface 312 corresponding to the first arc-shaped surface 301 on the side facing the slide block 3. The orthographic projection of the first arc-shaped surface 301 on the horizontal plane matches the contour of the arc-shaped cross-section 203 of the product 200, and the radius of curvature of the first arc-shaped surface 301 is equal to the radius of curvature of the arc-shaped cross-section 203 of the product 200. The slider 31 drives the second cutter 5 to swing back and forth along the first arc-shaped surface 301 of the slide block 3, thereby punching out the arc-shaped cross-section 203 of the product 200.

[0047] A first protruding ridge 313 is provided on the periphery of the slider 31 in the first horizontal direction. A first guide tooth 111 is provided on the side of the first guide rail facing the slider 31, which is in contact with the first protruding ridge 313. When the first platform 21 is moved towards the base 1 under force, the second cutter 5 swings back and forth in the first horizontal direction under the squeezing action of the first protruding ridge 313 and the first guide tooth 111. Both the first protruding ridge 313 and the first guide tooth 111 have a first inclined surface, so that the slider 31 can move towards the base 1 under pressure while driving the second cutter 5 to swing back and forth in the first horizontal direction, thereby punching the arc-shaped cross-section 203 of the product 200 in the first horizontal direction.

[0048] A second protruding rib 314 is provided on the periphery of the slider 31 in the second horizontal direction. A second guide tooth 121 corresponding to and abutting against the second protruding rib 314 is provided on the side of the second guide rail 12 facing the slider 31. When the first platform 21 is moved towards the base 1 under force, the second cutter 5 reciprocates along the first horizontal direction under the squeezing action of the second protruding rib 314 and the second guide tooth 121. Both the second protruding rib 314 and the second guide tooth 121 have a second inclined surface, so that the slider 31 can move towards the base 1 under pressure while driving the second cutter 5 to reciprocate in the second horizontal direction, thereby punching the arc-shaped cross-section 203 of the product 200 in the second horizontal direction.

[0049] In some embodiments, the first guide tooth 111 has a first distance from the base 1, and the second guide tooth 121 has a second distance from the base 1, wherein the first distance is greater than the second distance. Under pressure, the slider 31 drives the second cutter 5 to first reciprocate in the X direction, at which time the second cutter 5 does not reciprocate in the Y direction, and then reciprocates in the Y direction, at which time the second cutter 5 does not reciprocate in the X direction, thus punching out the arc-shaped cross-section 203 of the product 200, which can avoid the arc-shaped cross-section 203 of the product 200 from having a height difference.

[0050] In some embodiments, such as Figure 10As shown, the positioning component 32 includes a positioning plate 321 and a limiting block 322 connected to each other. The side of the positioning plate 321 facing the first platform 21 abuts against the shell 201 of the product 200 to limit the displacement of the product 200 in the X and Y directions and position the product 200. The other side abuts against the side of the second cutter 5 facing the first cutter 4, thereby transmitting the extrusion force applied by the first cutter 4 to the second cutter 5. A second inner ejector plate 7 is provided inside the second cutter 5. The second inner ejector plate 7 is slidably connected to the slide block 3. The second inner ejector plate 7 is provided with a second receiving cavity 701. The limiting block 322 is movably embedded in the second receiving cavity 701. Specifically, there is a first gap between the second cutter 5 and the limiting block 322, and a second gap between the second inner ejector plate 7 and the limiting block 322 and the connecting block. This allows the second cutter 5 to have a moving space between the second cutter 5, the second inner ejector plate 7 and the positioning member 32 when the slider 31 drives the second cutter 5 to swing back and forth relative to the slide block 3. At the same time, the positioning member 32 restricts the swing stroke of the second cutter 5. A connecting block 33 is provided at the center of the side of the slide block 3 facing the first platform 21. The connecting block 33 is detachably connected to the limiting block 322. By providing the connecting block 33, the fixed installation between the slide block 3 and the positioning member 32 can be achieved.

[0051] In an optional embodiment, a first connecting hole is provided at the center of the slide 3 in a vertical direction, and a second connecting hole corresponding to the first connecting hole is provided on the connecting block and the positioning member 32. Fasteners 34 are provided in both the first and second connecting holes. The first fastener 34 can be a bolt, and the threaded end of the first fastener 34 passes through the first and second connecting holes in sequence and is threadedly connected to the positioning member 32, thereby fixing the positioning member 32 at the center of the slide 3.

[0052] In some embodiments, a reset member 71 is provided on the second inner ejector plate 7. One end of the reset member 71 is connected to the second inner ejector plate 7, and the other end is connected to the limiting block 322, so that the second cutter 5 can be reset after swinging. By providing the reset member 71, the second cutter 5 can return to its initial position after swinging in the first horizontal direction, and the second cutter 5 can return to its initial position after swinging in the second horizontal direction, thereby avoiding height differences in the arc-shaped cross-section 203 of the product 200 and ensuring the quality and appearance of the product 200.

[0053] The reset member 71 includes a base 711, an elastic body 712, and a guide post 713. One end of the elastic body 712 is connected to the base 711, and the other end is connected to the guide post 713. The second inner release plate 7 is provided with a third accommodating cavity 702 in the vertical direction. The base 711 and the elastic body 712 are embedded in the third accommodating cavity 702 of the second inner release plate 7. The limiting block 322 has a first step and a second step connected to each other. The first step of the limiting block 322 abuts against the second inner release plate 7, and the first step is provided with a conical groove 3221 that is slidably connected to the guide post 713. The second step of the limiting block 322 is engaged with the connecting block 33. Optionally, the connecting block 33 is provided with a second protrusion on the side facing the limiting block 322, and the second step of the limiting block 322 is provided with a second groove that is engaged with the second protrusion. The elastic body 712 can be an existing spring. When the second cutter 5 and the second inner ejector plate 7 reciprocate relative to the slide block 3 in the X or Y direction, the elastic body 712 is deformed by force until the first protrusion 313 of the slider 31 passes through the first guide tooth 111 of the first guide rail 11 and the second protrusion 314 of the slider 31 passes through the second guide tooth 121 of the second guide rail 12. Then, by utilizing the elastic restoring force of the elastic body 712, the second cutter 5 and the second inner ejector plate 7 can be returned to center, that is, the central axis of the second cutter 5 corresponds to the central axis of the slide block 3.

[0054] In some embodiments, such as Figure 8 and Figure 11 As shown, the circumferential oscillating cutting die 100 also includes a first cutter holder 8, which is disposed on a first platform 21. The side of the first cutter holder 8 facing away from the first platform 21 abuts against the slider 31, and the first cutter 4 is embedded in the first cutter holder 8. A first cavity 81 is provided on the side of the first cutter holder 8 facing the slider 31, and a second cavity 315 corresponding to the first cavity 81 is provided on the side of the slider 31 facing the first cutter holder. A recycling space for accommodating blanking waste is formed between the first cavity 81 and the second cavity 315. After the arc-shaped cross-section 203 of the product 200 is blanked, the blanking waste remains in the recycling space and will not splash out and pollute the working environment, while also facilitating the collection and disposal of blanking waste.

[0055] like Figure 8 As shown, a first inner stripper plate 6 is provided inside the first cutter 4. One side of the first inner stripper plate 6 is connected to the first platform 21, and the other side abuts against the shell 201 of the product 200. The inner stripper plate and the positioning plate 321 simultaneously limit the shell 201 of the product 200, preventing the shell 201 of the product 200 from moving up and down under force during the punching process, thereby ensuring the finished product quality of the product 200.

[0056] like Figure 9As shown, the second platform 22 is provided with a first through hole 221 for the first guide rail 11 to pass through, and a second through hole 222 for the second guide rail 12 to pass through. It should be noted that the second through hole 222 can also allow the second guide tooth 121 to pass through. The first guide rail 11 and the second guide rail 12 improve the smoothness of the second platform 22 sliding in the vertical direction, further improving the finished product quality and appearance of the product 200.

[0057] like Figure 10 As shown, the first cutter 4 has a first cutting edge 41 on the side facing the positioning member 32.
