Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a continuous pipe clamp mold that can avoid long and short sides. Background Technology

[0002] Metal pipe clamps serve to support and fix pipelines, capable of withstanding the weight of the pipeline, the pressure of the medium, and harsh working environments. They possess high strength and stability, good corrosion resistance, and are widely used in various fields. The manufacture of metal pipe clamps generally uses progressive dies. These dies typically integrate punching, marking, cutting, and bending forming. Material is automatically fed by a feeder, and after bending, the pipe clamp is ejected from the die via lateral air blowing or a lateral pusher. These dies include a cutter to cut the material strip and a forming die to bend it. Existing progressive dies often have the bottom face of the cutter lower than the bottom face of the forming die. The manufacturing sequence is as follows: the strip is first pressed down by the strip cutter, then cut, and finally bent. The cut strip is in a free state at the bending station. When the radius of the forming die wears, the friction force experienced by the strip during bending and sliding becomes inconsistent, resulting in pipe clamps with uneven lengths, poor product compatibility, and even unusable conditions. Furthermore, since the bottom surface of the cutter is lower than the bottom surface of the upper forming die, the higher the height of the forming die, the longer the required length of the cutter. At this time, the cutter enters the concave die deeper, and the cutter is more prone to breakage and failure during high-frequency punching. Utility Model Content

[0003] In response to the problems raised in the background technology, the purpose of this utility model is to propose a continuous pipe clamp mold that can avoid long and short sides. During the bending process, the strip will not slip, the strip bending and forming stability is high, the product dimensional stability is high, and the cutting length is effectively shortened, extending the service life of the cutting blade. This solves the technical problems of existing pipe clamp molds that are prone to long and short sides during forming, poor product matching and usability, and easy breakage and failure of the cutting blade.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A continuous pipe clamp mold that avoids long and short sides, the continuous pipe clamp mold includes an upper mold assembly and a lower mold assembly. The upper mold assembly includes an upper mold base, an upper forming male, a movable forming male, a cutter, and a stripper plate. The upper forming male and the cutter are fixedly connected to the upper mold base. The movable forming male and the stripper plate are movably disposed on the upper mold base. The cutter, the movable forming male, and the upper forming male are arranged sequentially along the feeding direction. The stripper plate is disposed below the cutter, and the stripper plate has a first through hole for the cutter to pass through.

[0006] The horizontal plane at the lower end face of the movable forming male is lower than the horizontal plane at the lower end face of the unloading plate, and the horizontal plane at the lower end face of the cutter is higher than the horizontal plane at the lower end face of the upper forming male.

[0007] The lower mold assembly includes a lower mold base, a concave mold plate and a lower forming die fixedly disposed on the lower mold base, the lower forming die being disposed corresponding to the upper forming die, and the concave mold plate being disposed corresponding to the stripper plate, the cutter and the movable forming die.

[0008] To further explain, the upper molding male includes a molding surface that protrudes toward the lower molding male. The molding surface includes a first molding surface and a second molding surface. The first molding surface is connected to the end of the second molding surface near the movable molding male.

[0009] The lower forming male and the upper forming male are adapted to each other in shape;

[0010] The first molding surface is arc-shaped, and the second molding surface is planar;

[0011] The molding surface rotates downwards with the end of the first molding surface closest to the movable molding male as the center of rotation, moving away from the movable molding male.

[0012] To further explain, the angle A between the second forming surface and the horizontal plane is 5 to 15°.

[0013] To further explain, the height difference H between the horizontal plane where the lower end face of the cutter is located and the horizontal plane where the upper end of the first forming surface is located is 3 to 4 mm.

[0014] Furthermore, the lower mold assembly also includes a positioning block, which is fixedly connected to the lower mold base and is located on the side of the lower forming die away from the concave mold plate.

[0015] To further explain, the positioning block has a guide slope on the side facing the lower forming male, and the guide slope is inclined downward from the side close to the lower forming male to the side away from the lower forming male.

[0016] Furthermore, the upper mold assembly also includes a pressure spring and a stripping spring. One end of the pressure spring is fixedly connected to the upper mold base, and the other end of the pressure spring is fixedly connected to the movable forming male.

[0017] One end of the stripping spring is fixedly connected to the upper mold base, and the other end of the stripping spring is fixedly connected to the unloading plate.

[0018] Furthermore, the upper die assembly also includes a punching punch, which is fixedly connected to the upper die base. The stripper plate is provided with a second through hole for the punching punch to pass through, and the die plate is correspondingly arranged with the punching punch.

[0019] To further explain, the upper end face of the concave template is provided with a first clearance hole corresponding to the cutter, and the upper end face of the concave template is provided with a second clearance hole corresponding to the punch.

[0020] To further explain, the upper mold assembly also includes an upper pad and an upper fixing plate. The upper pad is fixed to the lower end face of the upper mold base, and the upper fixing plate is fixed to the lower end face of the upper pad. The cutter and the punch are both disposed on the upper fixing plate.

[0021] The lower mold assembly further includes a lower pad and a lower fixing plate. The lower fixing plate is fixed to the upper end face of the lower mold base, the lower pad is fixed to the upper end face of the lower fixing plate, the concave template is fixed to the upper end face of the lower pad, and the lower forming die is fixedly disposed on the upper end face of the lower fixing plate.

[0022] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0023] 1. By employing a staggered pressing structure between the movable forming die and the stripper plate, meaning the lower surface of the movable forming die is at a lower level than the lower surface of the stripper plate, the movable forming die presses the strip before the stripper plate. After the movable forming die presses the strip onto the surface of the concave die, the upper forming die continues to move downwards, forcing the strip to bend. As the upper forming die continues to descend, the stripper plate begins to contact the strip. When the upper and lower forming dies are fully closed, the strip is bent and formed. At the instant of bending, the cutter passes through the first through hole to cut the strip. Because this continuous die for pipe clamps bends the strip before cutting it, and the movable forming die presses the strip during bending, the strip receives stable and continuous pressure during bending, preventing slippage and resulting in high stability during bending. This prevents unevenness in the strip's shape and dimensions, ensuring high stability in the produced pipe clamps.

[0024] 2. Since the continuous die for the tube clamp is bent and then cut when forming the strip, the horizontal plane of the lower end face of the cutter is higher than the horizontal plane of the lower end face of the upper forming die, which shortens the length of the cutter and the length of the strip entering the die. At the same time, the delayed pressing of the stripper plate can guide and protect the cutter, effectively extending the service life of the cutter.

[0025] 3. By setting the forming surface to an inclined downward structure, during the downward movement of the upper forming mandrel, the strip can naturally shrink inward and bend during bending (here, inward shrinkage refers to the strip tilting downward towards the side of the moving forming mandrel along the inclined direction of the forming surface). That is, the strip is pre-bent and shaped under the action of the upper forming mandrel, and then stretches and presses the micro-parts under the cooperation between the upper and lower forming mandrels. This avoids the severe stretching of the strip during synchronous bending, which would cause wear on the mold components. In addition, the strip stretching deformation is small, and the product dimensional stability is high. Attached Figure Description

Detailed Implementation

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis.

[0034] like Figures 1 to 5 As shown, a continuous pipe clamp mold that avoids long and short sides is disclosed. The continuous pipe clamp mold includes an upper mold assembly 1 and a lower mold assembly 2. The upper mold assembly 1 includes an upper mold base 11, an upper forming male 12, a movable forming male 13, a cutter 14, and a stripper plate 15. The upper forming male 12 and the cutter 14 are both fixedly connected to the upper mold base 11. The movable forming male 13 and the stripper plate 15 are movably disposed on the upper mold base 11. The cutter 14, the movable forming male 13, and the upper forming male 12 are arranged sequentially along the feeding direction. The stripper plate 15 is disposed below the cutter 14, and the stripper plate 15 has a first through hole 151 for the cutter 14 to pass through.

[0035] The horizontal plane at which the lower end face of the movable forming male 13 is located is lower than the horizontal plane at which the lower end face of the unloading plate 15 is located, and the horizontal plane at which the lower end face of the cutter 14 is located is higher than the horizontal plane at which the lower end face of the upper forming male 12 is located.

[0036] The lower mold assembly 2 includes a lower mold base 21 and a concave template 22 and a lower forming male 23 fixedly disposed on the lower mold base 21. The lower forming male 23 is correspondingly disposed to the upper forming male 12, and the concave template 22 is correspondingly disposed to the unloading plate 15, the cutter 14 and the movable forming male 13.

[0037] The continuous die for avoiding long and short sides of the tube clamp adopts a high-low pressure structure. By using a staggered pressure structure between the movable forming manifold 13 and the unloading plate 15, that is, the horizontal plane of the lower end face of the movable forming manifold 13 is lower than the horizontal plane of the lower end face of the unloading plate 15, the movable forming manifold 13 presses the strip 101 before the unloading plate 15. After the movable forming manifold 13 presses the strip 101 onto the surface of the concave template 22, the upper forming manifold 12 continues to move downward, forcing the strip 101 to bend. As the upper forming manifold 12 continues to move downward, the unloading plate 15 begins to contact the strip 101. When the upper forming manifold 12 and the lower forming manifold 23 are fully closed, the bending of the strip 101 is completed. At the moment of bending, the cutter 14 passes through the first through hole 151 to cut the strip 101. Because this continuous die for pipe clamps bends the strip 101 before cutting it, meaning the bending action precedes the cutting, and the strip 101 is pressed down by the movable forming male 13 during bending, the strip 101 receives stable and continuous pressure during bending, preventing slippage and ensuring high bending stability. This prevents unevenness between long and short sides during forming, resulting in high stability in the shape and dimensions of the produced pipe clamps. Furthermore, because the continuous die bends the strip 101 before cutting it, the lower end face of the cutter 14 is at a higher horizontal level than the lower end face of the upper forming male 12. This shortens the length of the cutter 14 and its length entering the concave template 22. Simultaneously, the delayed pressing of the unloading plate 15 guides and protects the cutter 14, effectively extending its service life.

[0038] The aforementioned continuous pipe clamp mold that avoids long and short sides prevents the strip from slipping during bending, resulting in high bending stability of the strip 101 and high product dimensional stability. It also effectively shortens the length of the cutter 14 and extends its service life, solving the technical problems of existing pipe clamp molds that are prone to long and short sides during forming, poor product compatibility, and easy breakage and failure of the cutter.

[0039] To further explain, the upper molding man 12 includes a molding surface 121 protruding toward the lower molding man 23. The molding surface 121 includes a first molding surface 1211 and a second molding surface 1212. The first molding surface 1211 is connected to the end of the second molding surface 1212 near the movable molding man 13.

[0040] The lower forming die 23 serves as the concave mold of the upper forming die 12 and is adapted to the shape of the upper forming die 12;

[0041] The first molding surface 1211 is arc-shaped, and the second molding surface 1212 is planar;

[0042] The molding surface 121 rotates downwards with the end point of the first molding surface 1211 near the movable molding male 13 as the center of rotation and tilting in a direction away from the movable molding male 13.

[0043] Since the strip 101 is usually stored and transported in roll form, when the width of the strip 101 is narrow, the strip 101 may bend and sag after entering the mold. By setting the forming surface 121 to be inclined downward, and the shape of the lower forming male 23 is adapted to the shape of the upper forming male 12, the lower forming male 23 can avoid the sag and bend end of the strip 101, thus improving the smoothness of feeding. Furthermore, during the downward movement of the upper forming mandrel 12, the strip 101 can naturally retract inward during bending (here, inward retraction refers to the strip 101 tilting downwards along the inclined direction of the forming surface 121 towards the movable forming mandrel 13). That is, the strip 101 is pre-bent and shaped under the action of the upper forming mandrel 12, and then undergoes micro-stretching and pressing under the cooperation between the upper forming mandrel 12 and the lower forming mandrel 23. This avoids the severe stretching of the strip 101 during synchronous bending, which would cause wear on the mold components. Moreover, the stretching deformation of the strip 101 is small, resulting in high product dimensional stability. Since the tube clamp exhibits significant springback during the forming process, when the forming surface 121 is inclined, a downward positive pressure is applied at the bending angle where the first forming surface 1211 and the second forming surface 1212 connects as the mold moves downwards. This positive pressure forming at the bending angle results in less springback after the tube clamp is formed, leading to better product forming effect. Furthermore, under the pressure of the active forming element 13, the bending process is restricted by the pressure, and the strip is bent on one side, resulting in high product dimensional stability.

[0044] To further explain, by setting the first molding surface 1211 to be arc-shaped, the first molding surface 1211 can cooperate with the lower molding male 12 to form the arc-shaped structure in the middle of the tube clamp product. The second molding surface 1212 corresponds to the planar connection structure on one side of the arc-shaped structure of the tube clamp. Specifically, the lower molding male 23 has a molding cavity 231 that is recessed downwards corresponding to the first molding surface 1211. The lower molding male 23 also has a pressing plane 232 at the end of the molding cavity 231 near the concave template 22. The pressing plane 232 is horizontally arranged. When the movable molding male 13 presses against the concave template 22, it also presses against the pressing plane 232 (e.g., ...). Figure 3As shown, the material strip 101 portion of the movable forming male 13 corresponds to the planar connection structure on the other side of the tube clamp arc structure. Furthermore, by providing the pressing plane 232 at one end of the lower forming male 23 near the concave template 22, the pressing stability of the material strip 101 can be further improved.

[0045] like Figure 4 As shown, preferably, the angle A between the second molding surface 1212 and the horizontal plane is 5 to 15°.

[0046] When the pipe clamp is made of Q235 iron, the product has less springback, and the included angle A is 5-6°. When the pipe clamp is made of stainless steel, the product has more springback, and the included angle A is 10-15°.

[0047] like Figure 5 As shown, preferably, the height difference H between the horizontal plane where the lower end face of the cutter 14 is located and the horizontal plane where the upper end of the first forming surface 1211 is located is 3 to 4 mm.

[0048] By setting the height difference between the horizontal plane where the lower end face of the cutter 14 is located and the horizontal plane where the upper end of the first forming surface 1211 is located to be 3-4 mm, the material strip 101 is cut simultaneously when it is bent and formed under the action of the upper forming male 12.

[0049] Furthermore, the lower mold assembly 2 also includes a positioning block 24, which is fixedly connected to the lower mold base 21, and the positioning block 24 is located on the side of the lower forming die 23 away from the concave mold plate 22.

[0050] By setting the positioning block 24, when the material strip 101 enters from the feeding direction, it can abut against the positioning block 24, and at this time, the processing position of the material strip 101 is aligned, thereby realizing the positioning of the processing position of the material strip 101.

[0051] To further explain, the positioning block 24 is provided with a guide slope 241 on the side facing the lower forming male 23. The guide slope 241 is inclined downward from the side close to the lower forming male 23 to the side away from the lower forming male 23.

[0052] Since the strip 101 is usually stored and transported in roll form, when the width of the strip 101 is narrow, the strip 101 will warp upward after entering the mold. By setting the guide slope 241 on the positioning block 24, and the guide slope 241 is set downward from the side close to the lower forming male 23 to the side away from the lower forming male 23, the warped end of the strip 101 can be pressed down under the action of the guide slope 241.

[0053] Furthermore, the upper mold assembly 1 also includes a pressure spring 16 and a stripping spring 17. One end of the pressure spring 16 is fixedly connected to the upper mold base 11, and the other end of the pressure spring 16 is fixedly connected to the movable forming male 13.

[0054] One end of the stripping spring 17 is fixedly connected to the upper mold base 11, and the other end of the stripping spring 17 is fixedly connected to the unloading plate 15.

[0055] By setting the pressure spring 16 and the stripping spring 17, the movable forming manifold 13 and the stripping plate 15 are movably mounted on the upper mold base 11. When the upper mold base 11 moves downward, the pressure spring 16 is compressed, providing a force to the movable forming manifold 13 to press the material strip 101. When the stripping plate 15 presses down and contacts the material strip 101, the stripping spring 17 is compressed, and the stripping plate 15 presses down on the material strip 101. When the upper mold base 11 rises, the stripping spring 17 rebounds, acting on the stripping plate 15 to unload the material, preventing the material strip 101 from getting stuck on the cutter 14 and avoiding the material strip 101 from moving upward.

[0056] Furthermore, the upper mold assembly 1 also includes a punching punch 18, which is fixedly connected to the upper mold base 11. The stripper plate 15 is provided with a second through hole 152 for the punching punch 18 to pass through. The concave mold plate 22 is correspondingly arranged with the punching punch 18.

[0057] By setting the punch 18, punching can be performed on the strip 101.

[0058] Specifically, the horizontal plane at which the lower end face of the punching head 18 is located is at the same height as the horizontal plane at which the lower end face of the cutter 14 is located. When the strip 101 is bent and formed in place, the cutter 14 and the punching head 18 simultaneously complete the cutting and punching of the strip 101.

[0059] It should be noted that only one punch 18 is shown in the attached figure, and the number of punches 18 can be set according to the actual number of holes to be punched.

[0060] Specifically, the upper end face of the concave template 22 is provided with a first clearance hole 221 corresponding to the cutter 14, and the upper end face of the concave template 22 is provided with a second clearance hole 222 corresponding to the punch 18.

[0061] By providing the first clearance hole 221 and the second clearance hole 222, the first clearance hole 221 allows the cutter 14 to be inserted to avoid the cutter 14, while the second clearance hole 222 allows the punching punch 18 to be inserted to avoid the punching punch 18. At the same time, the first clearance hole 221 and the second clearance hole 222 can respectively achieve material clearance for cutting and punching.

[0062] To further explain, the upper mold assembly 1 also includes an upper pad 19 and an upper fixing plate 10. The upper pad 19 is fixed to the lower end face of the upper mold base 11, and the upper fixing plate 10 is fixed to the lower end face of the upper pad 19. The cutter 14 and the punching punch 18 are both disposed on the upper fixing plate 10.

[0063] The lower mold assembly 2 further includes a lower pad plate 25 and a lower fixing plate 26. The lower fixing plate 26 is fixed to the upper end surface of the lower mold base 21, the lower pad plate 25 is fixed to the upper end surface of the lower fixing plate 26, the concave template 22 is fixed to the upper end surface of the lower pad plate 25, and the lower forming die 23 is fixedly disposed on the upper end surface of the lower fixing plate 26.

[0064] The upper fixing plate 10 secures the cutter 14 and the punching head 18, while the upper pad 19 cushions the punching head 18 and the cutter 14, preventing damage to the upper die holder 11 from back impact during high-speed stamping. The lower fixing plate 26 secures the lower forming die 23, and the positioning block 24 is also fixed to the lower fixing plate 26. Furthermore, the lower pad 25 placed between the die plate 22 and the lower fixing plate 26 prevents excessive pressure on the die plate 22 during stamping, thus avoiding deformation of the lower fixing plate 26.

[0065] Specifically, the concave template 22, the lower pad 25, the lower fixing plate 26 and the lower mold base 21 are all provided with material discharge channels corresponding to the first clearance hole 221 and the second clearance hole 222, respectively, so as to discharge the waste material generated by the material strip 101 during cutting and punching.

[0066] To further explain, the upper mold base 11 and the upper pad 19 are respectively provided with a first guide through hole to accommodate the pressure spring 16, and the upper pad 19 and the upper fixing plate 10 are also respectively provided with a second guide through hole to accommodate the stripping spring 17, so as to realize the accommodation of the pressure spring 16 and the stripping spring 17, and enable the stripping spring 17 and the pressure spring 16 to be compressed in the vertical direction.

[0067] The working process of this utility model's continuous die for pipe clamps that avoids long and short sides is as follows:

[0068] The material strip 101 does not need to be lifted; it is pushed forward along the concave template 22. For example... Figure 2 As shown, the arrow indicates the feeding direction.

[0069] The material strip 101 is fed in one step and positioned against the positioning block 24. The upper mold assembly 1 moves downward, and the movable forming male 13 first contacts the material strip 101, forcing the pressure spring 26 to compress. The upper mold assembly 2 continues to move downward, and the upper forming male 12 first contacts the material strip 101, such as... Figure 2 As shown, because the upper forming male 12 and the lower forming male 23 have not yet closed, the strip 101 is shaped inward by the downward pressure of the upper forming male 12; the upper mold assembly 1 continues to descend, the unloading plate 15 begins to contact the strip 101, and the stripping spring 17 is compressed; when the upper forming male 12 and the lower forming male 23 are fully closed, the tube is formed in place, and simultaneously the cutter 14 and the punching punch 18 cut and punch the strip 101 (during this period, the strip is under continuous pressure, resulting in high bending stability, such as...). Figure 3 (As shown).

[0070] The upper die assembly 1 opens upwards, and each component moves away from the lower die assembly 2 in the reverse downward sequence, returning to the initial die position, and finally blowing out or ejecting the tube clamp. The strip 101 is then advanced one step again to complete the stamping operation of a single part.

[0071] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
