Description

Technical Field

[0001] This utility model relates to the technical field of leveling up-curved boards, and in particular to a high-efficiency leveling device for boards. Background Technology

[0002] The rolled sheet is wound onto the unwinding mechanism. When the rolled sheet is to be used, the worker starts the unwinding mechanism, which gradually unwinds the rolled sheet. Then, the worker uses a cutting device to gradually cut the unwound rolled sheet, resulting in multiple sections of sheet 1 with a certain length. The structure of sheet 1 is as follows. Figures 1-2 As shown, due to the internal stress of plate 1, the left and right edges of plate 1 are raised instead of flat. Therefore, workers need to level plate 1 before it can be used. Plate 1 is only 0.4mm thick and made of copper.

[0003] Used in a certain workshop Figures 3-6 The leveling mechanism shown is used to level the sheet 1. The leveling mechanism includes an upper mold A and a lower mold A. The upper mold A includes an upper support 2, an upper pad 3, and a stripper plate 4 that are fixed together from top to bottom. A punch 5 that passes through the upper pad 3 and the stripper plate 4 from bottom to top is fixed on the bottom surface of the upper support 2. A longitudinally arranged arc-shaped groove 6 is formed on the bottom surface of the punch 5. The lower mold A includes a base 7, a lower pad 8, and a concave template 9 that are fixed together from bottom to top. A strip-shaped pad 10 that passes through the lower pad 8 and the concave template 9 from top to top is fixed on the top surface of the base 7. A longitudinally arranged recess is formed on the top surface of the strip-shaped pad 10. An arc-shaped protrusion 11 that is arranged along its length is fixed at the bottom of the recess. The arc-shaped protrusion 11 cooperates with the arc-shaped groove 6.

[0004] The method by which the worker uses this leveling mechanism to level board 1 is as follows:

[0005] S1. The worker fixes the upper support 2 of the upper die A to the punch head of the stamping machine, and ensures that the arc groove 6 of the punch 5 is just above the arc protrusion 11 of the lower die A.

[0006] S2. The worker initially places the bottom surface of the middle part of the board 1 on the top surface of the arc-shaped protrusion 11, and then adjusts the position of the board 1 so that the board 1 is stably placed on the arc-shaped protrusion 11, such as... Figure 7 As shown, after the board 1 is placed stably, the worker removes the hand used to hold the board 1 [if the board 1 is not placed stably, the board 1 will slide off the arc-shaped protrusion 11];

[0007] Then the worker controls the punch head of the stamping machine to move downward. The punch head drives the upper support 2 of the upper die A to move downward. The upper support 2 drives the stripper plate 4 and the punch 5 to move downward synchronously. The punch 5 moves towards the plate 1 and presses the left and right edges of the plate 1 downward to gradually eliminate the internal stress of the plate 1.

[0008] When the arc-shaped groove 6 of the punch 5 mates with the arc-shaped protrusion 11, the sheet metal 1 is precisely engaged between the arc-shaped groove 6 and the arc-shaped protrusion 11 of the punch 5. Figure 8 As shown; after holding the pressure for a period of time, the punch head of the press is controlled to move upward, the punch head drives the upper support 2 to move upward, and the upper support 2 drives the stripper plate 4 and the punch 5 to move upward synchronously; after waiting for a period of time, the left and right edges of the plate 1 gradually spring back upward and eventually return to the horizontal state, thus finally achieving the leveling of the first plate 1.

[0009] S3. Workers can level all the boards 1 in the workshop by repeating step S2 multiple times.

[0010] However, although workers can level the board using this leveling mechanism, the following technical shortcomings still emerge in actual operation:

[0011] In step S2, since the bottom surface of the plate 1 is arc-shaped and the surface of the arc-shaped protrusion 11 is also arc-shaped, the worker needs to frequently adjust the position of the plate 1 in order to stably support the plate 1 on the top surface of the arc-shaped protrusion 11 without it falling off, so as to control the downward movement of the punch head of the press. The frequent adjustment of the position of the plate 1 by the worker undoubtedly consumes a lot of time, resulting in a long time required to complete the leveling of one plate 1. This not only increases the workload of the worker, but also prolongs the leveling time of subsequent plates 1, thus resulting in the technical defect of low leveling efficiency of the plate 1.

[0012] Therefore, there is an urgent need for a leveling device that can greatly reduce the workload of workers and greatly improve the efficiency of leveling boards. Utility Model Content

[0013] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency board leveling device that greatly reduces the workload of workers and greatly improves the efficiency of board leveling.

[0014] The purpose of this utility model is achieved through the following technical solution: a high-efficiency leveling device for leveling plates, which includes an upper mold B and a lower mold B. The upper mold B includes an upper support, an upper pad, and a stripper plate that are sequentially fixed together from top to bottom. A punch is fixed on the bottom surface of the upper support and passes through the upper pad and the stripper plate sequentially from bottom to bottom. A longitudinally arranged arc-shaped groove is opened on the bottom surface of the punch. Multiple blind holes are opened at intervals along the length direction of the bottom of the arc-shaped groove. The blind holes extend to the bottom surface of the upper support. A spring is installed in each blind hole. One end of the spring is fixed on the bottom surface of the upper support, and a pressure rod extending outside the arc-shaped groove is fixed on the other end. The bottom end of the pressure rod is spherical.

[0015] The lower mold B includes a base, a lower pad, and a concave template that are sequentially fixed together from bottom to top. A strip-shaped pad block is fixed on the top surface of the base and extends sequentially through the lower pad and the concave template. A longitudinally arranged groove is formed on the top surface of the strip-shaped pad block. An arc-shaped protrusion is fixed at the bottom of the groove along its length direction and the arc-shaped protrusion cooperates with the arc-shaped groove.

[0016] Two vertical plates are fixed on the top surface of the base, located on the left and right sides of the concave template respectively. Feed cylinders are fixed on the outer end faces of the two vertical plates. The piston rods of the two feed cylinders pass through the vertical plates, and support plates are fixed on the extended ends of the two support plates, which extend directly above the strip pad.

[0017] The upper support of the upper mold B and the upper pad are detachably fixed together by screws.

[0018] The spacing between any two adjacent compression bars is equal.

[0019] The diameter of the pressure rod is equal to the diameter of the blind hole.

[0020] The two support plates are symmetrically arranged about the strip pad.

[0021] This invention has the following advantages: it greatly reduces the workload of workers and greatly improves the efficiency of leveling boards. Attached Figure Description

[0043] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0044] like Figures 9-12 As shown, a high-efficiency leveling device for sheet metal includes an upper mold B and a lower mold B. The upper mold B includes an upper support 2, an upper pad 3, and a stripper plate 4, which are sequentially fixed together from top to bottom. The upper support 2 and the upper pad 3 of the upper mold B are detachably fixed together by screws. A punch 5 is fixed on the bottom surface of the upper support 2, which sequentially penetrates the upper pad 3 and the stripper plate 4 downwards. A longitudinally arranged arc-shaped groove 6 is formed on the bottom surface of the punch 5. A plurality of blind holes 12 are formed at intervals along the length of the bottom of the arc-shaped groove 6. The blind holes 12 extend to the bottom surface of the upper support 2. A spring 13 is provided in each blind hole 12. One end of the spring 13 is fixed to the bottom surface of the upper support 2, and a pressure rod 14 extending outside the arc-shaped groove 6 is fixed on the other end. The bottom end of the pressure rod 14 is spherical. The distance between any two adjacent pressure rods 14 is equal, and the diameter of the pressure rod 14 is equal to the diameter of the blind hole 12.

[0045] The lower mold B includes a base 7, a lower pad 8, and a concave mold 9 that are sequentially fixed together from bottom to top. A strip-shaped pad 10 is fixed on the top surface of the base 7, which sequentially passes through the lower pad 8 and the concave mold 9. A longitudinally arranged groove is formed on the top surface of the strip-shaped pad 10. An arc-shaped protrusion 11 is fixed at the bottom of the groove along its length direction. The arc-shaped protrusion 11 cooperates with the arc-shaped groove 6.

[0046] Two vertical plates 15 are fixed on the top surface of the base 7, located on the left and right sides of the concave template 9 respectively. Feed cylinders 16 are fixed on the outer end faces of the two vertical plates 15. The piston rods of the two feed cylinders 16 pass through the vertical plates 15, and support plates 17 are fixedly connected to the extended ends of the two support plates 17. The two support plates 17 extend directly above the strip pad 10, and the two support plates 17 are symmetrically arranged about the strip pad 10.

[0047] The working process of this utility model is as follows:

[0048] S1. The worker fixes the upper support 2 of the upper die B to the punch head of the press machine, and ensures that the arc groove 6 of the punch 5 is just above the arc protrusion 11 of the upper die B.

[0049] S2. Support the plate 1 stably on the top surface of the arc-shaped protrusion 11. The specific operation steps are as follows:

[0050] S21, The worker takes out a... Figures 1-2 The bottom surface of the plate 1 shown is initially placed on the top surface of the arc-shaped protrusion 11, and the plate 1 is held in place by hand.

[0051] S22. The worker controls the piston rod of the left feed cylinder 16 to extend to the right, causing the support plate 17 to move to the right. When the worker observes that the support plate 17 contacts the bottom surface of the left end of the plate 1, the worker controls the feed cylinder 16 to close. Then, the worker controls the piston rod of the right feed cylinder 16 to extend to the left, causing the support plate 17 to move to the left. When the worker observes that the support plate 17 contacts the bottom surface of the right end of the plate 1, the worker controls the feed cylinder 16 to close. At this time, the two support plates 17 lift the plate 1, as... Figure 13 As shown; then the worker removed his hand that was holding the board 1.

[0052] S23. Control the punch head of the press to move downwards. The punch head drives the upper support 2 of the upper die B to move downwards. The upper support 2 drives the stripper plate 4 and the punch 5 to move downwards synchronously, which in turn drives the spring 13 and the pressure rod 14 to move downwards synchronously. The bottom end of the pressure rod 14 first contacts the top surface of the plate 1, such as... Figure 14 As shown; as the upper support 2 continues to move downward, it drives the unloading plate 4 and the punch 5 to continue moving downward relative to the stationary pressure rod 14. At this time, the spring 13 is gradually compressed. When the upper support 2 moves downward to a certain stroke, the worker controls the stamping machine to shut down. At this time, under the elastic force of the spring 13, the plate 1 is just fixed between the arc-shaped protrusion 11 and each pressure rod 14, as shown. Figure 15 As shown;

[0053] S24. Control the piston rods of the two feed cylinders 16 to retract. The piston rods drive the support plate 17 to move outward, and the support plate 17 separates from the plate 1, thereby achieving stable support of the plate 1 on the top surface of the arc-shaped protrusion 11, as shown. Figure 16 As shown;

[0054] S3. Control the punch head of the press to continue moving downward. The punch head drives the upper support 2 of the upper die B to continue moving downward. The upper support 2 drives the stripper plate 4 and the punch 5 to move downward synchronously. The punch 5 presses the left and right edges of the plate 1 downward to gradually eliminate the internal stress of the plate 1.

[0055] When the arc-shaped groove 6 of the punch 5 mates with the arc-shaped protrusion 11, the sheet metal 1 is precisely engaged between the arc-shaped groove 6 and the arc-shaped protrusion 11 of the punch 5. Figure 17 As shown; after holding the pressure for a period of time, the punch head of the press is controlled to move upward. The punch head drives the upper support 2 to move upward, and the upper support 2 drives the stripper plate 4 and the punch 5 to move upward synchronously, thereby driving the pressure rod 14 to reset, as shown. Figure 18 As shown; after waiting for a period of time, the left and right edges of board 1 gradually bounced back upward and eventually returned to a horizontal state, thus finally achieving the leveling of the first board 1;

[0056] S4. Workers can repeat steps S2 to S3 multiple times to level all the boards 1 in the workshop.

[0057] As can be seen from step S2, the worker only needs to first process the bottom surface of the middle part of the plate 1 to be initially placed on the top surface of the arc-shaped protrusion 11, and then control the extension of the piston rods of the two feed cylinders 16 to lift the plate 1 through the two support plates 17; then, by moving the upper support 2 downward, the pressure rod 14 compresses the spring 13. Under the spring force of the compression spring 13, the plate 1 is fixed between the arc-shaped protrusion 11 and each pressure rod 14, thereby quickly and smoothly supporting the plate 1 on the top surface of the arc-shaped protrusion 11, and then quickly moving the plate 1 into the leveling station.

[0058] Therefore, it can be seen that this leveling device is superior to... Figures 3-8 The leveling mechanism shown can quickly and stably support the board 1 on the top surface of the arc-shaped protrusion 11 without the need for workers to frequently adjust the position of the board 1, thereby shortening the subsequent leveling time of the board 1. This not only greatly reduces the workload of workers, but also greatly improves the leveling efficiency of the board 1.
