Description

Technical Field

[0001] The present application relates to the field of stamping processing technology, and in particular to a correction device. Background Art

[0002] When producing thin workpieces with bending structures, a stamping die is usually used to stamp the part of the workpiece that needs to be bent, so that part of the workpiece structure is bent. Due to the stress of the workpiece itself, the bent part of the workpiece is prone to rebound after bending, resulting in a bending angle that does not meet the requirements. Therefore, the workpiece with an unqualified bending angle needs to be corrected. The commonly used correction device currently uses a plunger and a push block to correct the workpiece. When it is necessary to adjust the angle of the bent part of the workpiece, the position of the plunger is adjusted by adding or removing gaskets to the plunger, thereby achieving the purpose of adjusting the correction angle. However, this adjustment method requires the disassembly and reassembly of multiple parts, which takes a long time to debug and is complicated to operate. In addition, the adjustment angle is related to the thickness of the gasket, resulting in low adjustment accuracy and inability to achieve stepless adjustment. Utility Model Content

[0003] In view of the above, it is necessary to propose a correction device that can correct the bent portion of a workpiece, and that is convenient to adjust the correction angle and can achieve stepless adjustment.

When it is necessary to adjust the correction angle, the position of the adjusting member on the slider can be adjusted to adjust the angle of rotation of the adjusting member pushing the driving member, and then change the distance that the clamping member moves toward the slider, so that the deformation angle of the bent portion when the clamping member and the slider clamp the bent portion can be adjusted, that is, the correction angle can be adjusted. When adjusting the correction angle, the above-mentioned correction device only needs to adjust the position of the adjusting member in the slider, which is easy to operate.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0055] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0056] See Figure 1 The present invention provides a correction device 100 for correcting a bent portion 201 of a workpiece 200. The workpiece 200 is a strip-shaped structure before punching. That is, a plurality of sequentially connected workpieces 200 are punched out of a material strip. Each workpiece 200 includes a bent portion 201 and a main body 202. The bent portion 201 is formed by bending the main body 202 in a front-end processing device (not shown). The workpiece 200 is connected to an external traction device (not shown) to pull the workpiece 200. The correction device 100 includes a mold 10 and a correction mechanism 20.

[0057] Specifically, see Figure 1 、 Figure 2 and Figure 3The mold 10 includes an upper mold 11 and a lower mold 12 that fit together. The lower mold 12 is provided with a receiving groove 121 at one end facing the upper mold 11. It can be understood that the workpiece 200 is mounted between the lower mold 12 and the upper mold 11 by an external traction device. When the upper mold 11 and the lower mold 12 are closed, the upper mold 11 presses the workpiece 200 and moves it vertically to the lower mold 12. Both the lower mold 12 and the upper mold 11 can be plate-shaped structures. Before the workpiece 200 moves in the horizontal direction, the external traction device drives the workpiece 200 to move away from the lower mold 12 in the vertical direction, so that the workpiece 200 is higher than the lower mold 12, thereby avoiding friction between the bent portion 201 of the workpiece 200 and the lower mold 12 during the movement, which may affect the movement of the workpiece 200 or cause damage to the bent portion 201 of the workpiece 200. The upper mold 11 is connected to a power source, such as a cylinder, a punch, etc. When the upper mold 11 moves toward the lower mold 12, the external traction device stops driving the workpiece 200 to move horizontally. After the upper mold 11 abuts against the workpiece 200, it presses the workpiece 200 against the lower mold 12.

[0058] The correction mechanism 20 includes a sliding member 21, an adjusting member 22 and a clamping member 23. The adjusting member 22 can be adjustably connected to the sliding member 21 and passes through the sliding member 21 along the groove depth extension direction of the accommodating groove 121. The clamping member 23 includes a connected driving part 231 and a clamping part 232. The clamping part 232 is movably arranged in the accommodating groove 121 and is rotatably connected to the lower mold 12. The sliding member 21 is slidably arranged in the accommodating groove 121 and is placed on one side of the clamping part 232. The driving part 231 is arranged on the lower side of the sliding member 21 and corresponds to the adjusting member 22.

[0059] The sliding member 21 can be a block structure, which is slidably arranged in the accommodating groove 121. The adjusting member 22 can be a columnar structure, which can be adjustably connected to the sliding member 21. In the present embodiment, the adjusting member 22 is a headless bolt, and the adjusting member 22 is threadedly connected to the sliding member 21. When the position of the adjusting member 22 in the sliding member 21 needs to be adjusted, the adjusting member 22 can be rotated. Of course, the adjusting member 22 can also be other structural members that can be adjustably connected to the sliding member 21, which is not limited here. In the present embodiment, the clamping member 23 is roughly L-shaped, and the angle between the extension direction of its driving portion 231 and the extension direction of the clamping portion 232 is roughly 90°. The clamping portion 232 and the lower die 12 can be connected by a structure such as a rotating shaft. When the adjusting member 22 pushes the driving portion 231 to move, the clamping portion 232 can rotate, thereby cooperating with the sliding member 21 to clamp the bending portion 201 of the workpiece 200. In this embodiment, the center of gravity of the clamping portion 232 is on the side of its rotation axis away from the driving portion 231. Thus, when the adjusting member 22 is away from the driving portion 231, the clamping portion 232 rotates under its own gravity and then returns to its original position.

[0060] Among them, when closing the mold, the upper mold 11 presses the workpiece 200 to the lower mold 12 so that the bent portion 201 of the workpiece 200 is inserted between the sliding member 21 and the clamping portion 232. The upper mold 11 presses the sliding member 21 to move toward the driving portion 231, and the sliding member 21 drives the adjusting member 22 to push the driving portion 231 to move, and then drives the clamping portion 232 to rotate relative to the lower mold 12, so that the clamping portion 232 pushes the bent portion 201 of the workpiece 200 away from the side of the sliding member 21 until the sliding member 21 clamps the bent portion 201 to correct the bent portion 201.

[0061] The correction device 100 provided in the embodiment of the present application, when the upper mold 11 and the lower mold 12 are closed, the upper mold 11 presses the workpiece 200 to the lower mold 12, and then pushes the bent portion 201 of the workpiece 200 to between the sliding member 21 and the clamping member 23 of the correction mechanism 20, the upper mold 11 presses the sliding member 21 to move toward the driving member 231 of the clamping member 23, the sliding member 21 drives the adjusting member 22 to push the driving member 231 to move, the driving member 231 drives the clamping member 232 to rotate relative to the lower mold 12, and then the clamping member 232 moves toward the bent portion 201 of the workpiece 200, so that the clamping member 232 pushes the bent portion 201 of the workpiece 200 away from the side of the sliding member 21 until the sliding member 21 clamps the bent portion 201, so as to cooperate with the sliding member 21 to correct the bent portion 201. When the correction angle needs to be adjusted, the position of the adjusting member 22 on the sliding member 21 is adjusted to adjust the angle at which the adjusting member 22 pushes the driving member 231 to rotate, thereby changing the distance that the clamping portion 232 moves toward the sliding member 21. In this way, the deformation angle of the bending portion 201 when the clamping portion 232 and the sliding member 21 clamp the bending portion 201 can be adjusted, thereby achieving the adjustment of the correction angle. When adjusting the correction angle, the correction device 100 provided in the embodiment of the present application only needs to adjust the position of the adjusting member 22 in the sliding member 21, which is easy to operate. The position of the adjusting member 22 in the sliding member 21 can be freely adjusted, thereby achieving stepless adjustment.

[0062] In some embodiments, see Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The wall of the receiving groove 121 is provided with an oblique groove 1211. The distance between the oblique groove 1211 and the clamping portion 232 gradually increases along the direction from the lower mold 12 to the upper mold 11. The sliding member 21 is provided with a sliding protrusion 211 adapted to the oblique groove 1211. The sliding protrusion 211 is slidably disposed in the oblique groove 1211. The cooperation between the oblique groove 1211 and the sliding protrusion 211 can guide the movement of the sliding member 21. When the upper mold 11 presses the sliding member 21 downward, the sliding member 21 moves toward the clamping portion 232 under the guidance of the sliding protrusion 211 and the oblique groove 1211, and then cooperates with the clamping portion 232 to clamp the bent portion 201.

[0063] In some embodiments, see Figure 1 and Figure 3 The sliding member 21 is provided with a first inclined surface 212 on the side facing away from the material clamping portion 232. The plane on which the first inclined surface 212 lies is parallel to the extending direction of the sliding protrusion 211. The side wall of the receiving groove 121 corresponding to the first inclined surface 212 is provided with a second inclined surface 1212, and the first inclined surface 212 abuts against the second inclined surface 1212. The cooperation between the first inclined surface 212 and the second inclined surface 1212 allows the lower mold 12 to support the sliding member 21, thereby improving the stability of the sliding member 21 during sliding.

[0064] In some embodiments, see Figure 3 and Figure 5 The side of the sliding member 21 facing the material clamping portion 232 is provided with a groove 213. The groove 213 is provided near the end of the sliding member 21 that abuts the bent portion 201. The groove 213 is used to avoid the bent portion 201. It is understood that in order to meet the needs, some workpieces 200 need to add other structures during the production process, such as providing a protruding structure on the bent portion 201. The protruding structure can be formed by machining the bent portion 201 itself or by other components welded to the bent portion 201. By providing the groove 213 on the sliding member 21, the protruding structure of the bent portion 201 can be avoided.

[0065] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 The clamping portion 232 is provided with a clamping protrusion 2321. The clamping protrusion 2321 is provided at the end of the clamping portion 232 away from the driving portion 231 and on the side of the clamping portion 232 facing the sliding member 21. The clamping protrusion 2321 is used to abut the bent portion 201. By providing the clamping protrusion 2321, the clamping protrusion 2321 can be used to abut the bent portion 201 when the bent portion 201 is corrected. By providing the clamping protrusion 2321, the volume of the clamping portion 232 can be reduced, so that the bent portion 201 can be corrected even when the clamping portion 232 is rotated to a smaller angle.

[0066] In some embodiments, see Figure 1 、 Figure 4 and Figure 5The correction mechanism 20 also includes a first push assembly 24, which includes a first push member 241 and a first elastic member 242. The first push member 241 passes through the lower mold 12 and abuts against the sliding member 21. The first elastic member 242 abuts against the end of the first push member 241 away from the lower mold 12. The first elastic member 242 is used to push the first push member 241 toward the sliding member 21, so that the first push member 241 pushes the sliding member 21 to move toward the upper mold 11. The first push member 241 can be a rod-shaped structure, and the first elastic member 242 can be a spring, etc. By providing the first push assembly 24, after the mold is opened, the first push member 241 can be driven by the first elastic member 242 to move toward the sliding member 21, thereby causing the first push member 241 to push the sliding member 21 to reset.

[0067] In some embodiments, see Figure 1 、 Figure 4 and Figure 5 The correction mechanism 20 also includes a second resisting component 25, which includes a second resisting member 251 and a second elastic member 252. The second resisting member 251 passes through the lower mold 12 and abuts against the driving part 231. The second elastic member 252 abuts against the end of the second resisting member 251 away from the lower mold 12. The second elastic member 252 is used to push the second resisting member 251 toward the driving part 231 to make the second resisting member 251 push the clamping member 23 to rotate and reset. The second pushing member 251 can be a rod-shaped structure, and the second elastic member 252 can be a spring, etc. By setting the second pushing component 25, during the mold closing process, the clamping member 23 rotates, and the driving part 231 pushes the second pushing member 251 to move downward, thereby compressing the second elastic member 252, and the second elastic member 252 stores energy. When the mold is opened, the driving part 231 is not subjected to the pressure of the adjusting part 22, and the second elastic member 252 recovers its deformation, thereby driving the second pushing member 251 to move toward the driving part 231 to push the driving part 231 to rotate, and the driving part 231 drives the clamping part 232 to rotate to reset the clamping member 23.

[0068] In some embodiments, see Figure 3 and Figure 5The sliding member 21 is provided with a first avoidance groove 214, which is arranged at one end of the sliding member 21 away from the first push component 24 and at the side of the sliding member 21 away from the clamping part 232. The clamping part 232 is provided with a second avoidance groove 2322, which is arranged at one end of the clamping part 232 away from the driving part 231 and at the side of the clamping part 232 away from the sliding member 21. When the sliding member 21 and the clamping part 232 clamp the bending part 201 of the workpiece 200, the first avoidance groove 214 and the second avoidance groove 2322 are both used to avoid the other bending part 201 of the workpiece 200. It can be understood that a plurality of continuous workpieces 200 are arranged on the material strip. During correction, the sliding member 21 and the clamping member 23 correct the bending portion 201 of the workpiece 200 inserted between the sliding member 21 and the clamping member 23. By setting the first avoidance groove 214 and the second avoidance groove 2322, the bending portions 201 of the two workpieces 200 adjacent to the workpiece 200 being corrected can be avoided to prevent the sliding member 21 and the clamping member 23 from contacting the bending portions 201 of the other two workpieces 200, causing damage to the workpiece 200.

[0069] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 A clamping groove 2311 is provided on the side of the driving portion 231 opposite to the second pushing member 251, and the second pushing member 251 abuts against the bottom of the clamping groove 2311. By providing the clamping groove 2311, the stability of the second pushing member 251 when pushing the driving portion 231 can be improved.

[0070] In some embodiments, see Figure 1 The upper mold 11 is provided with a positioning pin 111 on the side facing the lower mold 12, and the lower mold 12 is provided with a positioning hole 122 on the side facing the upper mold 11, which is adapted to the positioning pin 111. By providing the positioning pin 111 and the positioning hole 122, the accuracy of the position of the upper mold 11 and the lower mold 12 can be improved when the mold is closed.

[0071] The working process of the calibration device 100 provided in the embodiment of the present application is roughly as follows:

[0072] First, see Figure 1 , connect the strip workpiece 200 to the external traction device, and set the workpiece 200 between the upper mold 11 and the lower mold 12, and drive the strip workpiece 200 to move horizontally through the external traction device so that one of the workpieces 200 corresponds to the correction mechanism 20.

[0073] Then, see Figure 2 、 Figure 4 and Figure 5The upper mold 11 moves toward the lower mold 12 to close the mold. The upper mold 11 presses the workpiece 200 to the lower mold 12. The bent portion 201 of the workpiece 200 corresponding to the correction mechanism 20 moves between the slide 21 and the clamping portion 232. Then the upper mold 11 continues to move toward the lower mold 12. The upper mold 11 pushes the slide 21 downward. While moving downward, the slide 21 moves toward the clamping portion 232. The adjusting member 22 connected to the slide 21 abuts against the driving portion 231, thereby pushing the driving portion 231 to move. The driving portion 231 drives the clamping portion 232 to rotate. The clamping portion 232 rotates toward the slide 21, thereby clamping the bent portion 201 of the workpiece 200 to correct the workpiece 200.

[0074] After calibration is complete, the upper die 11 moves away from the lower die 12. The first push assembly 24 pushes the slide 21 upward, causing the slide 21 to move upward and away from the clamping portion 232. The second push assembly 25 pushes the drive portion 231, which drives the clamping portion 232 to rotate away from the slide 21, completing the mold opening. The workpiece 200 now moves upward away from the lower die 12 and, under the traction of the external traction device, moves horizontally, so that the next workpiece 200 is aligned with the calibration mechanism 20. The above steps are repeated to calibrate the workpiece 200.

[0075] When the correction angle needs to be adjusted, the position of the adjusting member 22 in the sliding member 21 is adjusted so that the adjusting member 22 extends or retracts, and the adjusting member 22 pushes the clamping member 23 to rotate at an angle during correction, thereby adjusting the angle of the correction bending portion 201. Specifically, when the angle a between the bending portion 201 and the main body 202 is too large, the adjusting member 22 is adjusted to increase the length of the adjusting member 22 extending from the sliding member 21. In this way, the angle at which the adjusting member 22 pushes the clamping member 23 to rotate is increased during mold closing, thereby increasing the deformation angle of the clamping member 23 pushing the bending portion 201, thereby completing the correction. When the angle a between the bending portion 201 and the main body 202 is too small, the adjusting member 22 is adjusted to reduce the length of the adjusting member 22 extending from the sliding member 21. In this way, the angle at which the adjusting member 22 pushes the clamping member 23 to rotate is reduced during mold closing, thereby decreasing the deformation angle of the clamping member 23 pushing the bending portion 201, thereby completing the correction.

[0076] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims rather than the foregoing description, and all variations that come within the meaning and range of equivalents of the claims are intended to be embraced herein.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
