Description

Technical Field

[0001] The present application relates to the technical field of punching machines, and in particular to a punching machine frame for producing square pile end plates. Background Art

[0002] When producing square pile end plates, it is necessary to use a punching machine frame to punch the cut blanks. When processing the blanks, the existing punching machine frame places the blanks on the surface of the punching machine frame, fixes them with a fixing mechanism, and then performs the punching process. Due to the high intensity of the punching, it is easy to cause damage to the fixing mechanism on the punching machine frame, resulting in the scrapping of the blanks.

[0003] In this regard, China's patent application number is CN201922246767.3, which discloses a punch press frame for the production of square pile end plates. This solution mainly uses placement slots, punching holes, hydraulic push rods, push plates, telescopic rods, extrusion plates and springs to place the blank inside the punch frame for processing, thereby avoiding damage to the fixing mechanism on the punch frame due to the high intensity of the punching, which may lead to the scrapping of the blank.

[0004] However, in the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application found that the above technology has at least the following technical problems:

[0005] 1. In the above scheme, the square pile end plate lacks a lateral positioning structure when placed on the lower die seat, which makes it difficult to position when placed. In the prior art, a positioning pin is usually used, but the lateral impact force generated during stamping will gradually damage the positioning pin, resulting in positioning failure;

[0006] 2. The two hydraulic push rods apply force from both sides respectively, and the clamping force is transmitted through the spring. The forces on both sides are independent of each other and are affected by the spring elastic force. The clamping center is difficult to maintain, that is, the end plate of the square pile is prone to lateral displacement when clamped, resulting in low stamping accuracy. Utility Model Content

[0007] In order to make up for the above shortcomings, the present application provides a punch press frame for producing square pile end plates, aiming to improve the problems mentioned in the above background technology.

[0008] An embodiment of the present application provides a punch press frame for producing square pile end plates, including a support assembly and a clamping assembly.

[0009] The supporting assembly includes a lower die base and a support leg, the support leg is fixedly connected to the lower die base, the clamping assembly includes a clamping plate and a moving part, the clamping plates are hinged at both ends of the lower die base, each of the clamping plates is hinged with a connecting rod, and the two connecting rods are hinged to each other on the moving part.

[0010] In a specific embodiment, the support assembly further includes a bottom plate, and all the legs are fixedly connected to the bottom plate.

[0011] In the above implementation process, the base plate is used to improve the structural strength of all legs. In the prior art, the structure of the punch part is usually set on the lower die base, and impacts the square pile end plate on the lower die base downward. The punch structure is an existing conventional technology and has no direct connection with the technical problem to be solved by this solution, so the punch structure is not shown in the attached drawings.

[0012] In a specific embodiment, reinforcing ribs are provided on the lower die base.

[0013] In a specific embodiment, the clamping plate is hinged to the lower die base through the reinforcing ribs.

[0014] In the above implementation process, the reinforcing ribs are used to improve the strength of the splint hinge and to bear the lateral impact caused by stamping. The splint and the reinforcing ribs are alternately hinged together, which helps to improve the strength of the hinge.

[0015] In a specific embodiment, the splint is movably connected to a backing plate.

[0016] In a specific embodiment, a gasket is screwed onto the backing plate.

[0017] In the above implementation process, blocks are provided on both sides of the clamping plate, and arc-shaped slots are provided on both sides of the pad, which can restrict the pad on the clamping plate, and the back side of the pad is arc-shaped, which is connected to the clamping plate through an arc sliding connection, so as to maintain a good fit with the side of the square pile end plate. There are multiple gaskets, and a suitable number of gaskets are selected according to the clamping width of the square pile end plate. Countersunk screws are used to screw multiple gaskets to the pad, so that the relative angle of the two clamping blocks during clamping can be adjusted, and then the angle of the two connecting rods during clamping can be adjusted to make the angle as close to 180 degrees as possible. At this time, the lateral impact force generated during stamping will be offset by the two connecting rods, and only a small part of the impact force is transmitted to the screw rod. Since the screw rod is rotatably connected to the support leg, the impact force transmitted to the motor can be ignored.

[0018] In a specific embodiment, the movable member includes a slider and a screw rod, the slider is slidably connected to the leg, the two connecting rods are hinged to the slider, the slider is threaded through the screw rod, and the screw rod is rotatably connected to the leg.

[0019] In a specific embodiment, the moving part further includes a motor, the motor is arranged on the supporting leg, and the output end of the motor is connected to the screw shaft.

[0020] In the above implementation process, two motors are provided to drive their respective screws to rotate, thereby driving the slider to slide along the leg, and driving the two clamping plates to deflect through two pairs of connecting rods to achieve clamping and loosening of the other pile end plate.

[0021] Compared with the prior art, the beneficial effects of the present application are: the clamping assembly is hinged on the clamping plates on both sides of the lower mold base to clamp the square pile end plate, and the lateral impact force generated by the impact is transmitted to the two connecting rods with an angle of 180 degrees through the clamping plates, so that most of the impact force can be offset, and only a negligible impact force is transmitted to the moving parts, thereby improving the reliability of the moving parts, and by using a moving part to drive the deflection of the two connecting rods, the clamping center of the two clamping plates can be guaranteed during the clamping process.

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0029] See also Figure 1The present application provides a punch press frame for producing square pile end plates, including a support assembly 100 and a clamping assembly 200.

[0030] Among them, the clamping assembly 200 is hinged on the clamping plates 210 on both sides of the lower mold base 110 to clamp the square pile end plate, and the lateral impact force generated by the impact is transmitted to the two connecting rods 230 with an angle of 180 degrees through the clamping plates 210, so that most of the impact force can be offset, and only a negligible impact force is transmitted to the moving part 220, thereby improving the reliability of the moving part 220, and using a moving part 220 to drive the deflection of the two connecting rods 230 to ensure the clamping center of the two clamping plates 210 during the clamping process.

[0031] See also Figure 1-Figure 4 The support assembly 100 includes a lower mold base 110 and a support leg 120, the support leg 120 is fixedly connected to the lower mold base 110, and the clamping assembly 200 includes a clamping plate 210 and a moving part 220. The clamping plates 210 are hinged at both ends of the lower mold base 110, and each clamping plate 210 is hinged with a connecting rod 230, and the two connecting rods 230 are hinged to each other on the moving part 220.

[0032] See also Figure 1-Figure 2 The support assembly 100 further includes a bottom plate 130, and all the legs 120 are fixedly connected to the bottom plate 130. The bottom plate 130 is used to improve the structural strength of all the legs 120. In the prior art, the structure of the punch part is usually set on the lower die base 110, and the punch part strikes the square pile end plate on the lower die base 110 downward. The punch structure is an existing conventional technology and has no direct relationship with the technical problem to be solved by this solution, so the punch structure is not shown in the attached drawings.

[0033] See also Figure 1-Figure 2 , the lower die base 110 is provided with a reinforcing rib 140. The clamping plate 210 is hinged to the lower die base 110 through the reinforcing rib 140. The reinforcing rib 140 is used to improve the hinge strength of the clamping plate 210 and to bear the lateral impact generated by stamping. The clamping plate 210 and the reinforcing rib 140 are alternately hinged together, which helps to improve the hinge strength.

[0034] See also Figure 2 and Figure 3The clamping plate 210 is movably connected with a backing plate 240. A gasket 250 is screwed on the backing plate 240. Blocks are provided on both sides of the clamping plate 210, and arc-shaped grooves are provided on both sides of the pad 240, which can limit the pad 240 on the clamping plate 210, and the back side of the pad 240 is arc-shaped, and is connected to the clamping plate 210 through an arc surface sliding connection, so that it can maintain a good fit with the side of the square pile end plate. A plurality of gaskets 250 are provided, and a suitable number of gaskets 250 are selected according to the clamping width of the square pile end plate, and a plurality of gaskets 250 are screwed to the pad 240 using countersunk screws, so that the relative angle of the two clamping blocks during clamping can be adjusted, and then the angle of the two connecting rods 230 during clamping can be adjusted to make the angle as close to 180 degrees as possible. At this time, the lateral impact force generated during stamping will be offset by the two connecting rods 230, and only a small part of the impact force is transmitted to the screw rod 222. Since the screw rod 222 is rotatably connected to the support leg 120, the impact force transmitted to the motor 223 can be ignored.

[0035] See also Figure 2 and Figure 4 The moving part 220 includes a slider 221 and a screw rod 222. The slider 221 is slidably connected to the leg 120. Two connecting rods 230 are hinged to the slider 221. The slider 221 is threaded through the screw rod 222. The screw rod 222 is rotatably connected to the leg 120. The moving part 220 also includes a motor 223. The motor 223 is arranged on the leg 120. The output end of the motor 223 is connected to the screw rod 222. There are two motors 223, which respectively drive the respective screw rods 222 to rotate, and then drive the slider 221 to slide along the leg 120. The two pairs of connecting rods 230 drive the two clamping plates 210 to deflect, so as to achieve the clamping and loosening of the other pile end plate.

[0036] The working principle of the punching machine frame for producing the square pile end plate is as follows: in the initial state, the slider 221 is located below the leg 120, and the two clamping plates 210 remain in an outwardly expanded state, and the square pile end plate is placed on the lower die base 110. The motor 223 drives the slider 221 to move upward along the leg 120, and pushes the two clamping plates 210 to deflect inward through two pairs of connecting rods 230 to clamp the square pile end plate. At the same time, the angle between the two connecting rods becomes larger, close to 180 degrees. Therefore, the lateral impact generated during stamping is transmitted to the connecting rod 230 through the clamping plate 210, and most of the impact force is offset by the two connecting rods 230, while a small part of the impact force is transmitted to the motor 223, which improves the motor. The reliability of 223. Generally speaking, the screw rod 222 and the motor 223 are not as easy to improve the structural strength as the simple structure of the clamping plate 210 and the connecting rod. In summary, the clamping assembly 200 is hinged to the clamping plates 210 on both sides of the lower mold base 110 to clamp the square pile end plate, and the lateral impact force generated by the impact is transmitted to the two connecting rods 230 with an angle of 180 degrees through the clamping plate 210, so that most of the impact force can be offset, and only a negligible impact force is transmitted to the moving part 220, which improves the reliability of the moving part 220, and the method of using a moving part 220 to drive the deflection of the two connecting rods 230 can ensure the clamping center of the two clamping plates 210 during the clamping process.
