Description

Technical Field

[0001] This utility model relates to the technical field of simple bending auxiliary device for iron plate molds, specifically a simple bending auxiliary device for iron plate molds. Background Technology

[0002] Bending of sheet metal molds is an important step in the sheet metal mold processing. It usually involves using specific equipment and processes to bend the sheet metal mold into the required shape. For example, for some thin sheet metal molds, manual or electric bending machines can be used for processing; while for thick sheet metal molds, large equipment such as hydraulic bending machines may be required.

[0003] Chinese patent CN221362132U discloses a bending mechanism for processing metal workpieces, including a worktable, a bending frame fixed on the worktable, a fixed frame on the bending frame, a parallel frame inside the fixed frame, a bending template at the bottom of the parallel frame, bending rollers symmetrically arranged on both sides of the bending template, and bending rollers symmetrically arranged on the outer side of the bending rollers. This application utilizes the coordinated arrangement of the bending template, bending rollers, and bending rollers. Because the bending template, bending rollers, and bending rollers are staggered vertically, the plate-shaped or strip-shaped metal workpiece to be bent is pre-placed between bending rollers. At this point, the metal workpiece is located at the bottom of the bending template. As the bending template operates, it pushes the metal workpiece into the bending cavity. Simultaneously, both ends of the workpiece are bent between bending rollers, thus simultaneously bending both ends of the workpiece, improving work efficiency.

[0004] The bending mechanism for metal workpiece processing mentioned above has some problems in use. For example, when the length of the workpiece exceeds a certain range, the uneven distribution of its own weight and the force during processing can easily cause the workpiece to shift during the bending process, affecting the bending accuracy.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This embodiment provides a simple bending auxiliary device for iron plate molds, including a support plate 100 for supporting the iron plate mold, an extension plate 101 inserted into the right side of the support plate 100, a limiting member at the bottom of the support plate 100 to limit the extension plate 101 and prevent it from detaching, a support assembly at the bottom of the extension plate 101 for supporting the extension plate 101, and a fixing assembly at the left side of the support plate 100 that is fixedly connected to a workbench to support the iron plate mold on the surface of the workbench.

[0029] The fixing assembly includes two sets of fixing plates 200 fixedly installed on the upper and lower left sides of the support plate 100. The top surface of the lower fixing plate 200 is embedded with an abutment plate 201. The bottom of the two sets of lower fixing plates 200 are respectively threaded with hand-tightening bolts 202. The ends of the two sets of hand-tightening bolts 202 pass through the corresponding side fixing plates 200 and are fixedly connected to the bottom of the abutment plate 201. Through the setting of the support plate 100 and the extension plate 101, the support plate 100 provides support for the iron plate mold, preventing the workpiece from shifting during bending. At the same time, the extension plate 101 can be flexibly pulled out or retracted from the right side of the support plate 100 according to the actual size of the iron plate mold. For larger iron plate molds, the extension plate 101 can be pulled out to expand the support area and ensure that all parts of the iron plate mold can be stably supported. For smaller iron plate molds, the extension plate 101 can be retracted to avoid wasting space. This allows the device to adapt to iron plate molds of various specifications and improves the versatility of the device.

[0030] The limiting component includes a limiting hole 103 located at the bottom of the support plate 100 and extending along its length. A screw 104 is fixedly connected to the bottom of the extension plate 101. The end of the screw 104 passes downward through the limiting hole 103, and a nut 105 is threadedly connected to the end of the screw 104. The top of the nut 105 contacts the bottom of the support plate 100. Through the setting of the limiting component, the cooperation between the screw 104 and the limiting hole 103, and the locking of the extension plate 101 by the nut 105, the horizontal movement of the extension plate 101 can be accurately limited, ensuring the stable position of the extension plate 101 on the support plate 100 and preventing it from accidentally detaching during use, thus ensuring the normal operation of the device. At the same time, when it is necessary to adjust the extension length of the extension plate 101, simply loosen the nut 105 to easily move the extension plate 101, and tighten the nut 105 to fix it after adjustment. The operation is simple and convenient, improving the adjustability of the device.

[0031] The support assembly includes a mounting groove 300 formed at the bottom of the extension plate 101 and extending along its length. A round rod 311 is fixedly connected to the inner cavity on the right side of the mounting groove 300. A connecting sleeve 310 is rotatably sleeved on the surface of the round rod 311 located inside the mounting groove 300. An internally threaded tube 302 is fixedly connected to the left end of the connecting sleeve 310. The end of the internally threaded tube 302 is connected to a contact plate 304 through a connecting assembly. The end of the extension plate 101 is provided with a locking assembly that fixes the connecting sleeve 310 when the bottom of the contact plate 304 contacts the ground. By setting up the support assembly, stable support is provided for the extension plate 101, reducing the shaking or tilting of the device caused by uneven ground, ensuring the stability of the iron plate mold during processing, and further enhancing the overall stability, reducing the risk of device damage or iron plate mold deformation due to excessive local stress.

[0032] The connecting assembly includes fixed plates 307 fixedly installed on the top of both sides of the contact plate 304. A fixed rod 308 is fixedly installed between the two sets of fixed plates 307. A connecting rod 303 is rotatably sleeved on the surface of the fixed rod 308. The upper surface of the connecting rod 303 is provided with an external thread 306. The connecting rod 303 is threaded to the inner cavity of the internal thread tube 302 through the external thread 306. With the setting of the connecting assembly, the connecting rod 303 can rotate on the fixed rod 308, so that the contact plate 304 and the internal thread tube 302 can achieve a flexible rotational connection. This facilitates angle adjustment when adjusting the position of the contact plate 304, better adapting to different ground and support requirements. At the same time, rotating the connecting rod 303 can easily adjust the height of the contact plate 304 to adapt to different ground heights, further improving the stability and adaptability of the support.

[0033] The contact plate 304 has round holes 309 on both sides of its bottom. Each of the two sets of round holes 309 has a fixing bolt 305 inserted into its inner cavity. The two sets of fixing bolts 305 are threaded upward through the round holes 309 and threaded to the inner wall of the mounting groove 300. By setting the fixing bolts 305, the fixing bolts 305 fix the contact plate 304 to the inner wall of the mounting groove 300, which further enhances the connection stability between the contact plate 304 and the extension plate 101 and prevents the contact plate 304 from coming out of the inner cavity of the mounting groove 300 when it is stored.

[0034] The locking assembly includes a circular groove 404 formed inside the right side of the extension plate 101. A sliding plate 402 is slidably connected to the inner cavity of the circular groove 404. A plug-in plate 401 is fixedly connected to the left end of the sliding plate 402. One end of the plug-in plate 401 passes through the circular groove 404 and extends into the inner cavity of the mounting groove 300. The bottom of the connecting sleeve 310 has a plug-in groove 301 for the plug-in plate 401 to be inserted into. A spring 403 is connected to the right side of the sliding plate 402, and the other end of the spring 403 contacts the circular groove 404. On the right inner wall, a pull rod 400 is fixedly connected to the right end of the sliding plate 402. The end of the pull rod 400 passes through the circular groove 404 and extends to the outside of the extension. A handle 102 is fixedly connected to the end of the pull rod 400 located outside the extension plate 101. With the setting of the locking component, the plug plate 401 can be automatically inserted into the plug groove 301 of the connecting sleeve 310, realizing the automatic locking of the connecting sleeve 310, ensuring the stability of the support component during use, and avoiding the loosening of the connecting sleeve 310 due to human negligence.

[0035] Working principle;

[0036] When the workbench is too short to support the iron plate mold, first attach the four sets of fixing plates 200 on the left side of the bearing plate 100 to the end surface of the workbench, and make the top of the bearing plate 100 flush with the top of the workbench. Then, rotate the hand-tightening bolts 202 at the bottom of the two sets of fixing plates 200 so that the bolt ends penetrate the fixing plates 200 upwards and drive the abutment plate 201 to rise until the abutment plate 201 is pressed tightly against the surface of the workbench, thereby firmly fixing the bearing plate 100 to the workbench to support the iron plate mold.

[0037] If the size of the iron plate mold is large and the support range needs to be expanded, the extension plate 101 inserted into the right side of the support plate 100 can be pulled outward. The screw 104 at the bottom of the extension plate 101 will move along the limiting hole 103 opened at the bottom of the support plate 100. After adjusting the extension length of the extension plate 101, the nut 105 at the end of the screw 104 is tightened so that the top of the nut 105 contacts the bottom of the support plate 100, thereby restricting the horizontal movement of the extension plate 101 and preventing it from detaching from the support plate 100, ensuring that the extension plate 101 can stably cooperate with the support plate 100.

[0038] After the extension plate 101 extends, remove the two sets of fixing bolts 305 located at the bottom of the contact plate 304 to release the restriction on the contact plate 304. Hold the contact plate 304 and rotate it downwards. At the same time, drive the connecting sleeve 310 to rotate around the round rod 311. This will also press the plug plate 401 and compress the spring 403 in the inner cavity of the circular groove 404.

[0039] When the connecting sleeve 310 rotates to a suitable angle, the contact plate 304 approaches the ground, and the internal threaded tube 302 is perpendicular to the extension plate 101, the insertion groove 301 at the bottom of the connecting strip rotates to a position corresponding to the insertion plate 401. Thus, the insertion plate 401 is inserted into the inner cavity of the insertion groove 301 under the push of the spring 403, fixing the connecting sleeve 310 and preventing the connecting sleeve 310 from deflecting during use.

[0040] Then, the connecting rod 303 is rotated so that it is screwed out of the inner cavity of the internal thread tube 302, thereby adjusting the height of the contact plate 304 so that it can contact the ground. Then, the worker places the iron plate mold on the top of the support plate 100 and the surface of the extension plate 101, and then bends the iron plate mold through the bending mechanism on the surface of the workbench.

[0041] When the extension plate 101 needs to be stored after use, rotate the connecting rod 303 in the opposite direction so that the end of the connecting rod 303 is screwed into the internal thread tube 302. Then, pull the handle 102 outward to pull the pull rod 400. The pull rod 400 pulls the sliding plate 402 outward and compresses the spring 403. During the movement of the sliding plate 402, the plug plate 401 is driven to retract into the inner cavity of the circular groove 404 and disengage from the plug groove 301 on the surface of the connecting sleeve 310.

[0042] At this point, rotate the connecting plate upwards and insert the contact plate 304 into the mounting groove 300. At the same time, use the fixing bolts 305 to fix the contact plate 304. Then, loosen the nut 105 and push the extension plate 101 into the interior of the bearing plate 100. Finally, tighten the nut 105 to fix the extension plate 101.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
