Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to a misaligned pressing device and a punching machine. Background Technology

[0002] In industrial production, punching is frequently required for workpieces. Workpieces are typically fixed on a flexible plate. Before punching, the curved surface of the flexible plate needs to be flattened to ensure uniform stress on the workpiece; otherwise, the punching quality will be affected. Current technology uses rubber rollers to press the flexible plate, flattening its uneven areas. However, the gap between the upper and lower rollers is small, making it inconvenient and inefficient to manually insert the starting end of the flexible plate into the gap. Furthermore, during insertion, the flexible plate is pinched by hand, resulting in uneven stress and further increasing the curvature of the plate surface, creating a more pronounced arc. This tilts the relative position of the workpiece and the punching angle, ultimately affecting the uniformity of stress on the workpiece and the punching quality. Utility Model Content

[0003] Therefore, it is necessary to propose a staggered pressing device and a punching machine to address the above problems, so as to improve the efficiency of filling the flexible board between two rubber rollers, while avoiding exacerbating the unevenness of the flexible board surface during the filling process, thereby improving the efficiency and quality of punching.

[0027] This invention proposes a staggered pressing device and a punching machine. By changing the relative positions of the pressure rod and the support rod, the horizontal positions of the pressure rod and the support rod are altered, increasing the contact area between them and widening the gap. This allows the starting end of the flexible plate to pass through the increased gap, placing the flexible plate on the support rod and pressing it down. As the flexible plate moves forward after being pressed, the curvature of its surface decreases, the arc surface approaches a flat surface, and the angle of the workpiece placed on the flexible plate becomes more normal. Compared to existing technologies, this significantly improves punching efficiency, avoids exacerbating the unevenness of the flexible plate surface, ensures uniform stress on the workpiece, and improves punching quality.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0040] In the prior art, the gap between the upper and lower rubber rollers pressing the flexible plate is small. Manually inserting the starting end of the flexible plate into the gap is inconvenient, inefficient, and can easily exacerbate the unevenness of the flexible plate surface during the insertion process, thus affecting the punching efficiency and punching quality. To solve the above problems, this utility model provides a misaligned pressing device and a punching machine.

[0041] The following will be combined with the appendix Figures 1 to 6 The present invention provides a detailed description of a misaligned pressing device and a punching machine according to embodiments of the present invention.

[0042] Please see Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of a misaligned pressing device and a punching machine according to this utility model. Figure 2 This is the first exploded view of a misaligned pressing device and a punching machine according to this utility model.

[0043] A misaligned pressing device, comprising:

[0044] Mounting plate 1 has a rotating hole 11 and a riveting hole 12, with the riveting hole 12 located above the rotating hole 11.

[0045] The connecting plate 2 includes abutting portions 21 and connecting portions 22 arranged in a cross shape. The connecting portions 22 protrude from the surface of the abutting portions 21 and are nested in the riveting holes 12 to connect the connecting plate 2 and the mounting plate 1. The connecting portions 22 are provided with mounting holes 221 on both sides in the same direction as the rotating holes 11. The mounting holes 221 are located obliquely above the rotating holes 11.

[0046] Support rod 3 is rotatably mounted in pivot hole 11;

[0047] The pressure rod assembly 4 includes a pressure rod 41, a rotating component 42, and a fixed shaft 43. The rotating component 42 has an upper rotating hole 421 and a lower rotating hole 422 at both ends, and a magnetic device 44 is installed inside. One end of the fixed shaft 43 is fixedly connected to the mounting hole 221, and the other end is rotatably mounted in the upper rotating hole 421. The end of the support rod 3 is rotatably nested in the lower rotating hole 422. The pressure rod 41 and the rotating component 42 can rotate around the fixed shaft 43 from a first position to a second position and abut against the abutment part 21, or rotate from the second position to the first position. The first position is the lowest position of the pressure rod 41. In the first position, the rotating component 42 and the abutment part 21 are in contact and magnetically attracted to each other. The second position is the highest position of the pressure rod 41. There is a vertical distance between the first position and the highest position of the support rod 3, which allows the flexible plate to be squeezed through.

[0048] Specifically, the support rod 3 and the pressure rod 41 include rubber rollers. The support rod 3 is the lower rubber roller, and the pressure rod 41 is the upper rubber roller. In the prior art, the upper and lower rubber rollers are fixedly set and their relative positions are also fixed. A gap is set between the upper and lower rubber rollers for the flexible plate to pass through. After manually inserting the starting end of the flexible plate into the gap, the flexible plate is pulled forward, and the starting end of the flexible plate is wound around the roller of the drive mechanism. The starting end of the flexible plate is rolled by the drive mechanism, which in turn pulls the flexible plate to roll and rub forward in the gap between the upper and lower rubber rollers. The upper and lower rubber rollers squeeze the flexible plate, reducing the area of ​​the flexible plate with curvature. Since the relative positions of the upper and lower rubber rollers are fixed, the gap between them cannot be changed. When it is necessary to pass the starting end of a roll or a sheet of flexible plate through the gap, manual filling is inefficient. During the loading process, the flexible plate is pinched by hand, resulting in uneven force and exacerbating the curvature of the flexible plate surface, which in turn causes uneven force on the workpiece and affects the punching quality. By changing the relative positions of the pressure rod 41 and the support rod 3, the pressure rod 41 and the support rod 3 are staggered in the horizontal direction. The contact points between the support rod 3 and the flexible plate and the pressure rod 41 and the flexible plate are located at different points on the same plane. At the same time, the position of the pressure rod 41 in the vertical direction is adjustable, changing the gap between it and the support rod 3. When it is necessary to pass the starting end of a roll or a sheet of flexible plate through the gap, the gap is first increased, and the starting end of the flexible plate is allowed to pass through the increased gap and wound onto the roller of the drive mechanism. At this time, the flexible plate has contacted the lower rubber roller. Then, the upper rubber roller is adjusted to its original position, applying pressure to the flexible plate. The drive mechanism pulls the flexible plate forward, and different areas of the flexible plate are squeezed by the two staggered rubber rollers, making the curved surface tend to be flat and improving the punching quality.

[0049] The operation process is as follows: When it is necessary to insert the starting end of the flexible plate into the gap, the pressure rod assembly 41 is rotated from the first position to the second position. The rotating part is attracted to the second position by a magnetic material, which may include a magnet. One end of the flexible plate is placed on the support rod 3. The pressure rod assembly 4 is rotated from the second position to the first position, so that the upper surface of the flexible plate contacts the pressure rod 41 and the lower surface of the flexible plate contacts the support rod 3. During the rotation, the rotating part 42 and the pressure rod 41 rotate around the fixed axis 43. Compared with the existing technology of manually inserting the starting end of the flexible plate into the gap, this process greatly improves the punching efficiency, avoids aggravating the unevenness of the flexible plate surface, makes the workpiece subjected to uniform force, and improves the punching quality.

[0050] Please see Figure 2 and Figure 3 , Figure 3 This is a second exploded view of a misaligned pressing device and punching machine according to this utility model. In one embodiment, the mounting plate 1 includes a first mounting plate 14 and a second mounting plate 15, which are symmetrically arranged.

[0051] The first mounting plate 14 is provided with a first rotating hole 141, a second rotating hole 142, and a first riveting hole 143. The first riveting hole 143 is located above the first rotating hole 141 and the second rotating hole 142.

[0052] The second mounting plate 15 is provided with a third rotating hole 151, a fourth rotating hole 152 and a second riveting hole 153, with the second riveting hole 153 located above the third rotating hole 151 and the fourth rotating hole 152.

[0053] Specifically, the support rod 3 and the pressure rod assembly 4 have two ends, and a first mounting plate 14 and a second mounting plate 15 can be symmetrically arranged at the two ends to support the support rod 3 and the pressure rod assembly 4, so as to quickly adjust the relative position between the pressure rod assembly 4 and the support rod 3, thereby adjusting the gap distance, so that the starting end of the flexible plate can quickly pass through the adjusted gap and be wound on the reel of the drive mechanism, thereby improving the punching efficiency.

[0054] In one embodiment, the connecting plate 2 includes a first connecting plate 23 and a second connecting plate 24, which are symmetrically arranged.

[0055] The first connecting plate 23 includes a first abutting portion 231 and a first connecting portion 232 arranged in a cross shape. The first connecting portion 232 protrudes from the surface of the first abutting portion 231 and is nested in the first riveting hole 143 to connect the first connecting plate 23 and the first mounting plate 14. The first connecting portion 232 has a first mounting hole 2321 and a second mounting hole 2322 on both sides, which are in the same direction as the first rotating hole 141.

[0056] The second connecting plate 24 includes a second abutment portion 241 and a second connecting portion 242 arranged in a cross shape. The second connecting portion 242 protrudes from the surface of the second abutment portion 241 and is nested in the second riveting hole 153 to connect the second connecting plate 24 and the second mounting plate 15. The second connecting portion 242 has a third mounting hole 2421 and a fourth mounting hole 2422 on both sides, which are in the same direction as the third rotating hole 151. The third mounting hole 2421 is located obliquely above the third rotating hole 151, and the fourth mounting hole 2422 is located obliquely above the fourth rotating hole 152.

[0057] Specifically, between the first mounting plate 14 and the second mounting plate 15, and between the first connecting plate 23 and the second connecting plate 24, one set of support rods 3 and pressure rod assemblies 4 can be optionally provided, or two sets of support rods 3 and pressure rod assemblies 4 can be optionally provided, preferably two sets. The advantage is that it improves the extrusion efficiency. For example, if the flexible plate is not flattened in the first press, a second press can be performed to enhance the pressing effect, increase the flatness of the flexible plate surface, and thus improve the quality of punching.

[0058] Please see Figure 4 , Figure 4 This is a third exploded view of a misaligned pressing device and punching machine of the present invention. In one embodiment, the support rod 3 includes a first support rod 31 and a second support rod 32, which are symmetrically distributed. The two ends of the first support rod 31 are rotatably installed in the first rotating hole 141 and the third rotating hole 151, and the two ends of the second support rod 32 are rotatably installed in the second rotating hole 142 and the fourth rotating hole 152.

[0059] Specifically, the first support rod 31 and the second support rod 32 can rotate freely to support the flexible plate that moves forward.

[0060] In one embodiment, the pressure bar assembly 4 includes a first pressure bar assembly 44 and a second pressure bar assembly 45, which are symmetrically distributed.

[0061] The first pressure rod assembly 44 includes a first pressure rod 441, a first rotating member 442, a second rotating member 443, a first fixed shaft 444, and a second fixed shaft 445. The first rotating member 442 has a first rotating hole 4221 and a second rotating hole 4222 at both ends. The second rotating member 443 has a third rotating hole 452 and a fourth rotating hole 4432 at both ends. The first pressure rod 441 has both ends nested within the first rotating hole 4221 and the third rotating hole 452.

[0062] One end of the first fixed shaft 444 is fixedly connected to the first mounting hole 23221, and the other end is rotatably mounted in the second rotating hole 4222. One end of the first pressure rod 441 is rotatably nested in the first rotating hole 4221, and the other end of the first pressure rod 441 is rotatably nested in the third rotating hole 4431. The first pressure rod 441, the first rotating member 442, and the second rotating member 4222 can rotate around the first fixed shaft 444 and the second fixed shaft 445 from the first position to the second position for adsorption and fixation.

[0063] The second pressure rod assembly 45 includes a second pressure rod 451, a third rotating member 452, a fourth rotating member 453, a third fixed shaft 454, and a fourth fixed shaft 455. The third rotating member 452 has a fifth rotating hole 4521 and a sixth rotating hole 4522 at both ends, and the fourth rotating member 453 has a seventh rotating hole 4531 and an eighth rotating hole 4532 at both ends.

[0064] One end of the third fixed shaft 454 is fixedly connected to the second mounting hole 23321, and the other end is rotatably mounted in the sixth rotating hole 4522. The end of the second pressure rod 451 is rotatably nested in the fifth rotating hole 4521, and the other end of the second pressure rod 451 is rotatably nested in the seventh rotating hole 4531. The second pressure rod 451, the third rotating member 452, and the fourth rotating member 453 can rotate around the third fixed shaft 454 and the fourth fixed shaft 455 from the first position to the second position for adsorption and fixation.

[0065] When the first pressure rod 441 and the second pressure rod 451 are moved to the second position and the fourth position respectively, the flexible plate is placed on the first support rod 31 and the second support rod 32. Then the first pressure rod 41 and the second pressure rod 451 are moved to the first position and the third position respectively. During this process, the first rotating member 442 and the second rotating member 443 rotate with the first pressure rod 441 around the first fixed axis 444 and the second fixed axis 445. The third rotating member 452 and the fourth rotating member 453 rotate with the second pressure rod 41 around the third fixed axis 454 and the fourth fixed axis 455.

[0066] Compared to the existing technology that manually inserts the starting end of the flexible plate into the gap, this device greatly improves the punching efficiency, avoids aggravating the bending of the flexible plate surface, makes the workpiece subjected to uniform force, and improves the punching quality.

[0067] Please see Figure 5 , Figure 5 yes Figure 2 In the enlarged view at point A, in one embodiment, the connecting plate 2 is provided with a screw hole 25, and the mounting plate 1 is also provided with a vertical keyway hole 16 for adjusting the height of the connecting plate 2. The connecting plate 2 is fixedly connected to the mounting plate 1 through the cooperation of the nut, the screw hole 25, and the keyway hole 16. Its function is to adjust the height of the pressure rod assembly 4, thereby adjusting the gap between the pressure rod 41 and the support rod 3, facilitating control of the pressure on the flexible plate and improving the quality of punching.

[0068] Please see Figure 6 , Figure 6This is a fourth exploded view of a misaligned pressing device and punching machine according to this utility model. In one embodiment, wedge-shaped blocks 13 are symmetrically arranged on both sides of the abutment portion. The wedge-shaped blocks 13 are mounted on the mounting plate 1, and the bottom of the wedge-shaped blocks 13 is inclined. The rotating component 42 is attracted to the inclined surface of the wedge-shaped blocks 13 at a second position. The function is to reduce the rotation path of the pressure rod 41 and the rotating component 42, save time, and facilitate operation. The rotating component 42 is attracted to the wedge-shaped blocks 13 by its own magnetic device 44, which includes a magnet.

[0069] In one embodiment, the abutment portion 21 is provided with a magnetic component 211 with the opposite polarity to the rotating component 42. Its function is to increase the attraction between the rotating component 42 and the abutment portion 21, so that the rotating component 4 remains stable, thereby maintaining the stable pressing action on the flexible plate, enhancing the pressing effect, and helping to press the curved surface towards the plane. This is within the normal range of the angle area of ​​the workpiece placed on the flexible plate, thereby improving the efficiency and quality of punching.

[0070] In one embodiment, the system further includes a substrate 5, which has a fixing hole 51, and a mounting plate 1 has a connecting hole 17. The connecting hole 17 is located next to the rotating hole 12. The fixing hole 51 and the connecting hole 17 are connected by a nut to fix the substrate 5 and the mounting plate 1 together.

[0071] A punching machine includes a frame 6 and a misaligned pressing device according to any of the above embodiments, wherein the substrate 5 is disposed on the frame 6.

[0072] Compared to existing technologies, this invention changes the relative positions of the pressure rod 41 and the support rod 3 in the horizontal direction, increasing the contact area between them and widening the gap. The flexible plate's initial end then passes through this increased gap and is wound onto the drive mechanism's spool. At this point, the flexible plate is in contact with the support rod 3. The pressure rod 41 is then adjusted back to its original position, applying pressure to the flexible plate. The drive mechanism pulls the flexible plate forward, compressing it and reducing surface curvature, bringing the curved surface closer to a flat surface.
