Among the sheet metal production processes, the folding process is a very common processing technique, and folding processing equipment is often used in the folding process.

[0003] When bending sheet metal, bending equipment typically places the sheet metal on a worktable and then presses it with a mold to bend it. However, during the bending process, the pressure can cause the sheet metal to shift position, thus affecting product quality. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: during the folding process, the sheet metal may shift under pressure, thus affecting product quality.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 A sheet metal bending processing equipment for metal parts includes a base 1, an operating table 2 fixedly installed on the base 1, a mold groove 3 opened on the operating table 2, a support block 4 fixedly installed on the base 1, a lifting cylinder 5 fixedly installed on the support block 4, a rectangular block fixedly installed on the output end of the lifting cylinder 5, and a mold 6 fixedly installed on the rectangular block.

[0022] When bending sheet metal, the sheet metal is first placed on the operating table 2, and then the lifting cylinder 5 drives the mold 6 to move vertically downward. After the mold 6 is inserted into the mold groove 3, the bending of the sheet metal is achieved.

[0023] The operating table 2 is symmetrically fixedly equipped with L-shaped support frames 7. Each of the two support frames 7 is symmetrically fixedly equipped with a first spring rod 8. One end of the multiple first spring rods 8 is fixedly equipped with a pressure plate 9. The operating table 2 is equipped with a transmission assembly for driving the pressure plate 9 to move vertically downward. The transmission assembly includes a horizontal bar 10 fixedly installed on a rectangular block, a second spring rod 11 fixedly installed on the horizontal bar 10, and a top block 12 fixedly installed on one end of the second spring rod 11. The top block 12 is located directly above the pressure plate 9. The elastic coefficient of the second spring rod 11 is greater than that of the first spring rod 8.

[0024] During the process of the output end of the lifting cylinder 5 driving the mold 6 to move vertically downward through the rectangular block, it will drive the second spring rod 11 and the top block 12 to move vertically downward through the crossbar 10 until the top block 12 contacts the pressure plate 9. Since the elastic coefficient of the second spring rod 11 is greater than that of the first spring rod 8, the first spring rod 8 is stretched, which drives the pressure plate 9 to move vertically towards the sheet metal. Only after the pressure plate 9 contacts the sheet metal does the second spring rod 11 begin to compress. Thus, under the elastic force of the second spring rod 11, the pressure plate 9 is always in contact with the sheet metal and tightly limits the sheet metal on the operating table 2. This avoids the deviation of the sheet metal position under the pressure of the folding during the bending process, effectively improving the quality of the product.

[0025] An anti-slip pad is fixedly installed on the lower surface of the pressure plate 9. The anti-slip pad is made of rubber and can increase the friction between the pressure plate 9 and the sheet metal, further limiting the sheet metal from shifting.

[0026] A rectangular groove is provided in the mold groove 3. A push rod 13 is vertically slidably installed in the rectangular groove. A slider 14 is fixedly installed at both ends of the push rod 13. A sliding hole is provided on the surface of each slider 14. A slide rod 15 is vertically slidably installed in the sliding hole. A stop block 16 is fixedly installed at one end of the slide rod 15. The slide rod 15 is vertically fixedly installed on the base 1.

[0027] After the folding is completed, the slider 14 can be driven to slide on the slide bar 15 towards the stop 16, thereby driving the push rod 13 to slide into the mold groove 3, thus pushing out the folded sheet metal in the mold groove 3, preventing the folded sheet metal from adhering to the mold groove 3, and making it easier to remove the folded sheet metal.

[0028] A movable block 17 is slidably sleeved on the slide rod 15, and a telescopic spring 18 is sleeved on the slide rod 15. The two ends of the telescopic spring 18 are fixedly connected to the movable block 17 and the base 1, respectively. L-shaped support rods are fixedly installed at both ends of the mold 6. A first strong magnet 19 is fixedly installed at one end of the support rod. A second strong magnet 20 is fixedly installed on the surface of the movable block 17. The first strong magnet 19 is located directly above the second strong magnet 20.

[0029] When mold 6 moves vertically downward, it drives the first strong magnet 19 to move towards the second strong magnet 20 until they attract each other. As mold 6 continues to move downward, it drives the moving block 17 to slide downward on the slide rod 15, compressing the telescopic spring 18. After the folding is completed, under the action of magnetic force, the first strong magnet 19 will drive the moving block 17 to move vertically upward through the second strong magnet 20 until it contacts the slider 14 and drives the slider 14 to move together, thereby driving the ejector rod 13 to move vertically upward until the slider 14 contacts the stop block 16. Under the obstruction of the stop block 16, the first strong magnet 19 will separate from the second strong magnet 20. Finally, under the action of the ejector rod 13's own weight and the telescopic spring 18, the ejector rod 13 will move to its initial position.

[0030] In this invention, as the output end of the lifting cylinder 5 moves the mold 6 vertically downward via the rectangular block, it drives the pressure plate 9 vertically towards the sheet metal via the transmission assembly. Once the pressure plate 9 contacts the sheet metal, the second spring rod 11 begins to compress. Thus, under the elastic force of the second spring rod 11, the pressure plate 9 is in constant contact with the sheet metal and tightly limits the sheet metal to the operating table 2. This prevents the sheet metal from deviating from its position under the pressure of the folding edge, effectively improving the quality of the product.

[0031] In summary, regarding the technical problem of sheet metal displacement during the folding process due to pressure, which affects product quality, the proposed solution involves the coordinated action of the support frame 7, the first spring rod 8, the pressure plate 9, and the transmission assembly to fix the sheet metal during folding. The solution works as follows: the output of the lifting cylinder 5 moves the mold 6 vertically downwards via a rectangular block, which in turn moves the pressure plate 9 vertically towards the sheet metal. Once the pressure plate 9 contacts the sheet metal, the second spring rod 11 compresses, ensuring constant contact between the pressure plate 9 and the sheet metal, firmly securing it to the worktable 2. This solution effectively solves the problem and prevents positional deviation of the sheet metal under folding pressure, thus improving product quality.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
