Description

Technical Field

[0001] This utility model relates to the field of torsion forming device technology, and in particular to a torsion forming device for metal stamping parts. Background Technology

[0002] Automobiles are assembled from a variety of metal parts. Some parts, after being stamped, need to be twisted to form parts with specific twisted shapes.

[0003] Chinese utility model patent with publication number CN221515860U discloses a clamping device for a bending machine for metal structural parts, including a fixed ring. A fixed cylinder is fixedly connected to the top of the inner wall of the fixed ring. A first spring is provided on the inner side of the fixed cylinder. The top of the first spring is fixedly connected to the top of the inner side of the fixed ring. A lifting rod is fixedly connected to the bottom of the first spring. A groove is provided on the front side of the lifting rod.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: when using the above-mentioned clamping device to twist and form metal stampings, it can only clamp the metal stampings and it is difficult to perform twisting processing. It is necessary to use an additional twisting device to twist or bend the clamped metal stampings multiple times, which is inconvenient. Therefore, it is necessary to improve the design of the related technologies. Utility Model Content

[0005] To solve the above problems, this utility model provides a metal stamping part torsion forming device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a metal stamping part torsion forming device, including a base plate, on which two vertical and parallel mounting plates are provided, and each mounting plate is provided with a clamping torsion mechanism, the clamping torsion mechanism including a clamping component for clamping the metal stamping part to be torsion and a driving component for driving the clamping component to rotate.

[0007] By adopting the above technical solution, the clamping component can clamp the metal stamping to be twisted, and the driving component can drive the clamping component to rotate. By controlling the clamping components on both sides to rotate in opposite directions, the operator can perform twist forming processing on the metal stamping to be twisted. This eliminates the need to use additional twist forming tools to twist or bend the metal stamping multiple times after fixing it with a fixture, thus improving the twist forming efficiency of the metal stamping.

[0008] Furthermore, the clamping assembly includes a base plate disposed between two mounting plates and a clamping plate slidably mounted on the base plate. The clamping plate is provided in two parallel configurations. The clamping assembly also includes a power unit disposed on the base plate for driving the two clamping plates to move closer or further apart.

[0009] By adopting the above technical solution, the operator can drive the two clamping plates to move closer or further apart through the power unit. In this way, the two clamping plates cooperate to clamp the metal stamping part to be twisted, so that the drive component can drive the clamping component and the metal stamping part to rotate, thereby completing the twisting forming process of the metal stamping part.

[0010] Furthermore, a sliding block is fixed to one end of each clamping plate, and a slot is provided through the base plate to slide and engage with the sliding block. There are two slots arranged symmetrically, and the cross-section of the sliding block is in the shape of an "I".

[0011] By adopting the above technical solution, it is ensured that the clamping plate can slide back and forth on the substrate.

[0012] Furthermore, the power unit includes a power motor fixed to the side wall of the base plate near the mounting plate, a drive gear fixed to the output end of the power motor, a threaded rod rotatably mounted on the side of the base plate near the mounting plate, a driven gear fixedly sleeved on the threaded rod and meshing with the drive gear, a movable block sleeved on the threaded rod and threadedly connected, and a connecting rod hinged to the side wall of the movable block. There are two connecting rods, and the ends of the two connecting rods away from the movable block are respectively hinged to two sliding blocks.

[0013] By adopting the above technical solution, after the staff starts the power motor, the power motor drives the drive gear to rotate, thereby causing the driven gear meshing with the drive gear and the threaded rod fixed to the driven gear to rotate. Since the movable block is threadedly connected to the threaded rod, and the connecting rod is hinged to both the movable block and the sliding block, the movable block reciprocates along the axial direction of the threaded rod, so that the two connecting rods pull the sliding block and make the two sliding blocks move closer or further apart. The two clamping plates cooperate to clamp the metal stamping part to be twisted.

[0014] Furthermore, two fixing blocks are fixed on the side wall of the clamping plate near the mounting plate, which are symmetrically arranged with respect to the sliding block. A connecting bolt that is clearance-fitted to the fixing block is provided through the fixing block, and the end of the connecting bolt is threadedly connected to the sliding block.

[0015] By adopting the above technical solution, the connecting bolts detachably connect the fixing block and the sliding block, thereby allowing the clamping plate to be detachably installed on the base plate. This makes it convenient for workers to change different clamping plates according to the shape of the metal stamping part to be clamped and twisted, so as to clamp metal stamping parts of various shapes such as round tubes and plates. This is beneficial for the metal stamping part torsion forming device to torsion form metal stamping parts of different shapes.

[0016] Furthermore, rubber sheets are fixed to the sides of the two clamps that are close to each other.

[0017] By adopting the above technical solution, the rubber sheet is made of rubber material, which has good elastic properties and reduces the probability of damage to the metal stamping parts when clamped by two plates.

[0018] Furthermore, the drive assembly includes a central shaft rotatably mounted on the mounting plate, a worm gear fixedly sleeved on the central shaft, a rotary motor fixed on the mounting plate, a worm fixed to the output end of the rotary motor and meshing with the worm gear, a mounting ring fixedly sleeved on the central shaft, a diagonal rod fixed on the mounting ring, an annular plate fixed to the end of the diagonal rod away from the mounting ring, and a fixing rod fixed on the annular plate. The diagonal rod and the fixing rod are provided in multiples and are evenly distributed about the axis of the central shaft. The ends of the multiple fixing rods away from the mounting plate are fixed to the side wall of the substrate near the mounting plate.

[0019] By adopting the above technical solution, after the operator starts the torsion motor, the torsion motor works and drives the worm to rotate, thereby driving the worm wheel meshing with the worm, the central shaft fixed to the worm wheel, the mounting ring fixed to the central shaft, the inclined rod fixed to the mounting ring, the annular plate fixed to the inclined rod, and the base plate fixed by the fixing rod to rotate. This causes the clamping components set on the base plate and the clamped metal stampings to rotate. The two sets of drive components cooperate to perform torsion forming processing on the metal stampings to be torsion.

[0020] Furthermore, one of the mounting plates is fixed at the bottom to the top of the base plate, and a connecting plate is fixed on the other mounting plate near its bottom. A fastening bolt with clearance fit is provided through the connecting plate. The top of the base plate is provided with threaded holes that are threadedly connected to the fastening bolts. There are multiple threaded holes, and the arrangement direction of the multiple threaded holes is parallel to the axial direction of the central shaft.

[0021] By adopting the above technical solution, after unscrewing the fastening bolts, the workers can install the movable mounting plate at different positions on the base plate, thereby adjusting the distance between the two mounting plates and the two sets of clamping components, which facilitates the torsion forming of metal stamping parts of different lengths.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This application eliminates the need for additional torsion forming tools to torsion or bend the metal stamping parts multiple times after using a fixture to fix them, thus improving the torsion forming efficiency of the metal stamping parts.

[0024] 2. In this application, after the worker starts the power motor, the power motor drives the drive gear to rotate, thereby causing the driven gear meshing with the drive gear and the threaded rod fixed to the driven gear to rotate. Since the movable block is threadedly connected to the threaded rod, and the connecting rod is hinged to both the movable block and the sliding block, the movable block reciprocates along the axial direction of the threaded rod, so that the two connecting rods pull the sliding block and cause the two sliding blocks to move closer or further away from each other. The two clamping plates cooperate to clamp the metal stamping part to be twisted. Attached Figure Description

[0031] The technical solutions in 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, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-5 As shown in the figure, this application discloses a metal stamping torsion forming device, including a base plate 1. Two vertical and parallel mounting plates 2 are provided on the base plate 1. Each mounting plate 2 is provided with a clamping torsion mechanism 3. The clamping torsion mechanism 3 includes a clamping component 31 for clamping the metal stamping to be torsion and a driving component 32 for driving the clamping component 31 to rotate.

[0033] The clamping assembly 31 can clamp the metal stamping to be twisted, and the driving assembly 32 can drive the clamping assembly 31 to rotate. By controlling the clamping assemblies 31 on both sides to rotate in opposite directions, the operator can perform twist forming processing on the metal stamping to be twisted. This eliminates the need to use additional twist forming tools to twist or bend the metal stamping multiple times after fixing it with a fixture, thus improving the twist forming efficiency of the metal stamping.

[0034] The clamping assembly 31 includes a base plate 311 disposed between two mounting plates 2 and clamping plates 312 slidably mounted on the base plate 311. Two clamping plates 312 are provided and parallel to each other. The clamping assembly 31 also includes a power unit 313 disposed on the base plate 311 for driving the two clamping plates 312 closer together or further apart. In this embodiment, a sliding block 4 is fixed to one end of each clamping plate 312. A slot 3111 is provided through the base plate 311 to slide and engage with the sliding block 4. Two slots 3111 are provided and symmetrically arranged. The cross-section of the sliding block 4 is "I"-shaped.

[0035] The operator can drive the two clamping plates 312 to move closer or further apart through the power unit 313, so that the two clamping plates 312 cooperate to clamp the metal stamping part to be twisted, so that the drive component 32 drives the clamping component 31 and the metal stamping part to rotate, thereby completing the twisting forming process of the metal stamping part.

[0036] Regarding the power unit 313, specifically: the power unit 313 includes a power motor 3131 fixed on the side wall of the base plate 311 near the mounting plate 2, a drive gear 3132 fixed to the output end of the power motor 3131, a threaded rod 3133 rotatably mounted on the side of the base plate 311 near the mounting plate 2, a driven gear 3134 fixedly sleeved on the threaded rod 3133 and meshing with the drive gear 3132, a movable block 3135 sleeved on the threaded rod 3133 and threadedly connected, and a connecting rod 3136 hinged to the side wall of the movable block 3135. There are two connecting rods 3136, and the ends of the two connecting rods 3136 away from the movable block 3135 are respectively hinged to two sliding blocks 4.

[0037] After the operator starts the power motor 3131, the power motor 3131 drives the drive gear 3132 to rotate, thereby causing the driven gear 3134 meshing with the drive gear 3132 and the threaded rod 3133 fixed to the driven gear 3134 to rotate. Since the movable block 3135 is threadedly connected to the threaded rod 3133, and the connecting rod 3136 is hinged to both the movable block 3135 and the sliding block 4, the movable block 3135 reciprocates along the axial direction of the threaded rod 3133, so that the two connecting rods 3136 pull the sliding block 4, and make the two sliding blocks 4 move closer or further away from each other. The two clamping plates 312 cooperate and clamp the metal stamping part to be twisted.

[0038] Two fixing blocks 3121 are fixed on the side wall of the clamping plate 312 near the mounting plate 2, which are symmetrically arranged with respect to the sliding block 4. A connecting bolt 31211 with clearance fit is provided through the fixing block 3121, and the end of the connecting bolt 31211 is threadedly connected to the sliding block 4.

[0039] Connecting bolts 31211 detachably connect the fixing block 3121 and the sliding block 4, thereby allowing the clamping plate 312 to be detachably installed on the base plate 311. This facilitates the operator to change different clamping plates 312 according to the shape of the metal stamping part to be clamped and twisted, enabling the clamping of various shapes of metal stamping parts such as round tubes and plates. This is beneficial for the metal stamping part twisting forming device to twist and form metal stamping parts of different shapes. To effectively protect the metal stamping part to be twisted, rubber sheets 5 are fixed to the sides of the two clamping plates 312 that are close to each other.

[0040] Regarding the drive assembly 32, specifically: the drive assembly 32 includes a central shaft 321 rotatably mounted on the mounting plate 2, a worm gear 322 fixedly sleeved on the central shaft 321, a rotary motor 323 fixed on the mounting plate 2, a worm 324 fixed to the output end of the rotary motor 323 and meshing with the worm gear 322, a mounting ring 325 fixedly sleeved on the central shaft 321, a diagonal rod 326 fixed on the mounting ring 325, an annular plate 327 fixed to the end of the diagonal rod 326 away from the mounting ring 325, and a fixing rod 328 fixed on the annular plate 327. The diagonal rod 326 and the fixing rod 328 are provided in multiples and are evenly distributed about the axis of the central shaft 321. The ends of the multiple fixing rods 328 away from the mounting plate 2 are all fixed to the side wall of the base plate 311 near the mounting plate 2.

[0041] After the operator starts the torsion motor, the torsion motor works and drives the worm 324 to rotate, thereby driving the worm wheel 322 meshing with the worm 324, the central shaft 321 fixed to the worm wheel 322, the mounting ring 325 fixed to the central shaft 321, the inclined rod 326 fixed to the mounting ring 325, the annular plate 327 fixed to the inclined rod 326, and the base plate 311 fixed by the fixing rod 328 to rotate. This causes the clamping assembly 31 set on the base plate 311 and the clamped metal stamping to rotate. The two sets of drive assemblies 32 cooperate to perform torsion forming processing on the metal stamping to be torsion.

[0042] One of the mounting plates 2 is fixed at the bottom to the top of the base plate 1, and a connecting plate 6 is fixed at the bottom of the other mounting plate 2. A fastening bolt 61 with clearance fit is provided through the connecting plate 6. The top of the base plate 1 is provided with a threaded hole 11 that is threaded to the fastening bolt 61. There are multiple threaded holes 11, and the arrangement direction of the multiple threaded holes 11 is parallel to the axial direction of the central shaft 321.

[0043] After unscrewing the fastening bolts 61, the workers can install the movable mounting plates 2 at different positions on the base plate 1, thereby adjusting the distance between the two mounting plates 2 and the two sets of clamping components 31, which facilitates the torsion forming of metal stamping parts of different lengths.

[0044] The working principle of the metal stamping torsion forming device in this embodiment is as follows: the clamping component 31 can clamp the metal stamping to be torsion, and the driving component 32 can drive the clamping component 31 to rotate. By controlling the clamping components 31 on both sides to rotate in opposite directions, the operator can perform torsion forming processing on the metal stamping to be torsion. This eliminates the need to use additional torsion forming tools to torsion or bend the metal stamping multiple times after fixing it with a fixture, thus improving the torsion forming efficiency of the metal stamping.

[0045] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
