[0002] High-strength alloy formwork is widely used in construction due to its high strength, corrosion resistance and reusability, especially in infrastructure construction, bridge construction and other fields. This type of formwork is usually made of high-strength alloy material. High-strength alloy formwork greatly reduces the use of wood in construction, reduces resource waste, and can be reused many times and recycled. During the construction process, high-strength alloy formwork is flexible and fast to assemble, with high dimensional matching, which greatly improves the construction speed and quality. The punching process of high-strength alloy formwork is an important part of the production process. Punching not only needs to ensure accuracy, but also needs to meet the production needs of workpieces of different specifications.

[0003] The material of the high-strength alloy template is S550GD+AZM120 (zinc-magnesium-aluminum coating on both sides 120g / m2), which is formed by laser welding. The width is 7 specifications of 100, 150, 200, 250, 300, 350 and 400mm, among which the workpiece bottom plate is the most important component.

[0023] Example 1

[0024] This embodiment proposes an alloy template 3 punching device. When the specifications of the workpiece change, servo feeding, servo shaping, bidirectional multi-row punching and bottom plate web punching are integrated.

[0025] like Figure 1 As shown, the punching device includes a feeding device 1, a clamping mechanism 2, a bidirectional punching machine 4 and a bottom punching machine 5; Figure 3 As shown, the feeding device 1 includes a frame 11, a running board 15 and a roller 17, wherein the running board 15 is slidably mounted on the frame 11, and the roller 17 is rotatably mounted on the frame 11; the clamping mechanism 2 is mounted on the running board 15, and the clamping mechanism 2 has a clamping claw, which clamps on the template 3 and drives the template 3 to move on the roller 17; Figure 6 As shown, the bidirectional punching machine 4 includes a base frame 44, a fixed row punching die 48 and a dynamic row punching die 46, wherein the fixed row punching die 48 is fixedly mounted on the base frame 44, and the dynamic row punching die 46 is slidably mounted on the base frame 44, and the fixed row punching die 48 and the dynamic row punching die 46 are used to punch holes on both sides of the template 3 (such as Figure 2The bottom punching machine 5 is installed on the base frame 44 and is located at the rear side of the two-way punching machine 4, and is used to punch holes in the belly of the template 3.

[0026] A plurality of guide rails are mounted on the frame 11, and the running board 15 is mounted on these guide rails so as to reciprocate along the guide rails. The roller 17 is mounted on the frame 11 and can rotate freely, and is mainly used to support the template 3 to move forward. The clamping mechanism 2 is mounted on the running board 15, and the template 3 is clamped by the clamping claws to ensure the stability of the template 3 during the punching process and prevent the template 3 from being displaced during the punching process. The clamping mechanism 2 drives the template 3 to move on the (height-adjustable) roller 17 to ensure the accurate positioning and feeding of the template 3. The fixed row punching die 48 is fixed on the base frame 44, and the dynamic row punching die 46 is mounted on the base frame 44 through a slider pair, and multiple rows of punching can be completed during movement. The two sides of the template 3 are punched respectively by the fixed row and dynamic row dies to ensure the accuracy and synchronization of the punching. The bottom punching machine 5 is mounted on the rear side of the bidirectional punching machine 4, and is specifically used to punch the belly of the template 3. The position of the punching machine is adjustable, and the punching depth and position can be adjusted according to templates 3 of different sizes.

[0027] like Figure 3 As shown, the frame 11 is equipped with a first linear guide slider pair 16, which includes a guide rail and a slider. The guide rail is fixed on the frame 11, and the running board 15 is installed on the slider. The guide rail is fixed on the frame 11 to provide a stable motion path; the slider is connected to the running board 15, and the slider can slide smoothly linearly along the guide rail to ensure that the running board 15 maintains precise positioning during the motion. The cooperation between the guide rail and the slider reduces the motion resistance and improves the stability and life of the equipment.

[0028] The frame 11 is provided with a first servo motor 12 and two parallel first ball screw pairs 14, the first ball screw pair 14 includes a lead screw and a nut, the first servo motor 12 is connected to the lead screw through a first coupling 13, and the running board 15 is connected to the nut. The servo motor provides power, and after being connected to the ball screw pair through a coupling, the running board 15 is driven to reciprocate along the guide rail through the nut. This structure can achieve high-precision control, and the servo motor can be speed-regulated and accurately positioned according to actual needs to ensure the accuracy and efficiency of the template 3 feeding. Through the design of the ball screw pair, the friction loss can be greatly reduced, and the stability and working efficiency of the feeding device 1 can be improved.

[0029] like Figure 4 , Figure 5As shown, the clamping mechanism 2 includes a base 21, a fixing plate 25 and a driving mechanism, wherein the base 21 is fixed on the sports car board 15, the fixing plate 25 is located on one side of the base 21, and the end of the fixing plate 25 is a lower clamping jaw 26, the driving mechanism is mounted on the fixing plate 25, and an upper clamping jaw 24 is mounted on one side of the driving mechanism. The driving mechanism includes a push cylinder 22 and a push rod 23, one end of the push cylinder 22 is hinged to the base 21, and the other end is connected to the push rod 23, the other end of the push rod 23 is hinged to the upper clamping jaw 24, the lower clamping jaw 26 is provided with a groove, the upper clamping jaw 24 is embedded in the groove and is rotatably connected to the lower clamping jaw 26.

[0030] One end of the push cylinder 22 is fixed to the base 21 by a hinged connection, ensuring the stability and support force of the push cylinder 22 when working, and ensuring the freedom of movement of the push cylinder 22. One end of the push rod 23 is connected to the piston of the push cylinder 22, and the other end is hinged to the upper clamp 24, ensuring that when the push rod 23 moves, the upper clamp 24 can perform precise clamping action through the force transmitted by the push rod 23. The groove of the lower clamp 26 provides support and fixation for the upper clamp 24, ensuring that the upper clamp 24 can move stably and smoothly complete the clamping action during the clamping process. The clamp is designed with a specific gripping area to ensure uniform distribution of the clamping force and avoid deformation of the template 3 during the clamping process. The design of the clamping mechanism 2 ensures that the template 3 is always stable during the punching process to prevent punching accuracy problems caused by loose template 3.

[0031] like Figure 6 As shown, the base frame 44 is provided with a second servo motor 41, a second ball screw pair 43 and a second linear guide slider pair 45, the dynamic row punching die 46 is installed on the second linear guide slider pair 45 and connected to the second ball screw pair 43, the second servo motor 41 is connected to the second ball screw pair 43 through the second coupling 42, and the second servo motor 41 drives the dynamic row punching die 46 to move on the second linear guide slider pair 45 along a direction perpendicular to the movement direction of the template 3 through the second ball screw pair 43.

[0032] The second servo motor 41 is used to drive the dynamic row of punching dies 46 to perform precise linear motion along the second linear guide slider pair 45. Through the high-precision control of the servo motor, the dynamic row of punching dies 46 can be accurately adjusted in position to adapt to different workpiece specifications. The second ball screw pair 43 is connected to the servo motor and transmits the driving force from the servo motor to ensure smooth linear motion of the dynamic row of punching dies 46. The second linear guide slider pair 45 is installed on the base frame 44 to provide stable support and guiding effects. The guide slider pair ensures that the dynamic row of punching dies 46 does not deviate when moving in a direction perpendicular to the template 3, thereby avoiding die deviation. Through the precise control of the servo motor, the dynamic row of punching dies 46 can be accurately moved within the specified range to meet the punching requirements of workpieces of different specifications.

[0033] like Figure 7 As shown, the dynamic row punching die 46 includes a first hydraulic cylinder 461, a die base plate 462, a connecting sleeve 463, a third linear guide slider pair 464, a movable die seat 465, a guide body 466, an insert 468 and a punch 469. The fixed row punching die 48 has the same structure as the fixed row punching die 48. The die base plate 462 is installed on the second linear guide slider pair 45, the third linear guide slider pair 464 is installed on the die base plate 462, the movable die seat 465 is installed on the third linear guide slider pair 464, the first hydraulic cylinder 461 is connected to the movable die seat 465 through a connecting sleeve 463, the guide body 466 is installed on the die base plate 462, and an insert 468 is installed on the guide body 466. The punch 469 is installed at one end of the movable die seat 465 and can punch the template 3 through the insert 468.

[0034] The die base plate 462 is mounted on the second linear guide slider pair 45 to provide support for the base 21 of the entire dynamic row punching die 46. The stable installation of the die base plate 462 ensures the stability and positioning accuracy of the subsequent components. The third linear guide slider pair 464 is mounted on the die base plate 462 to support the dynamic die seat 465 and ensure that it moves in the correct direction during the die punching process. The dynamic die seat 465 is mounted on the third linear guide slider pair 464 and driven by the first hydraulic cylinder 461 to complete the key actions in the punching process. The hydraulic cylinder is connected to the dynamic die seat 465 through the connecting sleeve 463 to provide efficient power transmission and ensure that the movement force of the punch 469 is sufficient. The guide body 466 is mounted on the die base plate 462 to ensure the accuracy of the punch 469 during movement. The insert 468 is mounted on the guide body 466 to play a role in precise positioning and improving the punching accuracy. The insert 468 can use a highly wear-resistant material to ensure that it will not wear during high-frequency punching. The punch 469 is installed at the end of the movable die holder 465. Under the push of the movable die holder 465, the punch 469 passes through the insert 468 to punch the template 3. Through this precise structural combination, the dynamic punching die 46 can ensure high precision and high efficiency in the punching process, and can adapt to the punching requirements of templates 3 of different specifications.

[0035] like Figure 8 As shown, a bottom die seat 467 for supporting the template 3 is installed on one side of the guide body 466, and the dynamic punching die 46 also includes a guide wheel assembly 47, and the guide wheel assembly 47 includes a moving wheel 471, a fixed wheel 472 and a clamping cylinder 473. The moving wheel 471 is located at both ends of the bottom die seat 467 and can be lifted and moved, and the fixed wheel 472 and the clamping cylinder 473 are installed on the upper side of the bottom die seat 467.

[0036] The bottom die seat 467 is fixedly mounted on the guide body 466 to ensure stability during the punching process and prevent the template 3 from being displaced during the punching process. The bottom die seat 467 can effectively support and position the template 3 by supporting the belly of the template 3, and cooperate with the clamping cylinder 473 to clamp the template 3. The moving wheels 471 are located at both ends of the bottom die seat 467, and can be lifted and lowered, so as to adjust the contact pressure of the template 3 during the working process, ensuring that the template 3 can smoothly enter the punching die. Through the cooperation of the moving wheel 471, the fixed wheel 472 and the clamping cylinder 473, it is ensured that the template 3 does not produce any deviation during the punching process, and the template 3 is prevented from being deformed or displaced due to excessive impact, thereby ensuring the punching accuracy.

[0037] like Fig. 9 As shown, the bottom punching machine 5 has a fixed seat 52, and the fixed seat 52 is slidably installed on the base frame 44 along a direction perpendicular to the moving direction of the template 3. A second hydraulic cylinder 51 is installed on the fixed seat 52, and a punch 469 is installed on the bottom side of the second hydraulic cylinder 51. A gap groove 53 is provided in the middle of the fixed seat 52, and the template 3 is inserted into the gap groove 53 to punch holes in the abdomen.

[0038] The sliding structure of the fixed seat 52 can adjust the position of the bottom punching machine 5 according to the specifications of different templates 3 to adapt to different types of punching requirements. The function of the hydraulic cylinder is to provide the impact force required for punching, and the belly of the template 3 is punched through the punch 469. A gap groove 53 is provided in the middle of the fixed seat 52, and the template 3 is punched in the belly by inserting into the groove. The existence of the gap groove 53 ensures the stability of the template 3 during the punching process. This design achieves a balance between the punching of the abdomen and the stability of the template 3. The efficient cooperation of the hydraulic cylinder and the punch 469 effectively improves the speed and accuracy of the bottom punching. The design of the sliding fixed seat 52 and the gap groove 53 ensures the accuracy when adapting to templates 3 of different sizes and reduces the number of manual adjustments.

[0039] In summary, the equipment can simultaneously complete automatic feeding, clamping, bidirectional multi-row punching, and web punching, while also reducing costs and reducing the difficulty of operation for staff. The feeding and changing specifications are all servo-controlled, with high precision, reduced labor, and multiple uses of one machine, thus improving the applicability of the same punching machine. The feeding device 1 is equipped with multiple rollers 17 to reduce friction, and the clamping position is designed with double cylinders, which makes the clamping and feeding more stable.

[0040] Example 2

[0041] This embodiment provides a punching method of the alloy template 3 punching device as described in Embodiment 1, comprising:

[0042] The clamping claw of the clamping mechanism 2 is clamped on one side of the template 3 to be punched, and the sports car plate 15 moves on the frame 11, thereby driving the template 3 to move on the roller 17 and enter the bidirectional punching machine 4;

[0043] The dynamic row punching die 46 moves toward the side close to the fixed row punching die 48, and then the fixed row punching die 48 and the dynamic row punching die 46 punch holes on both sides of the template 3;

[0044] The clamping mechanism 2 continues to drive the template 3 to move forward and enter the bottom punching machine 5. While the bidirectional punching machine 4 punches holes on both sides of the template 3, the bottom punching machine 5 punches holes on the belly of the template 3.

[0045] The method greatly improves the punching efficiency by combining automatic clamping, bidirectional punching and bottom punching. The movement of the template 3 is precisely controlled by a servo motor to ensure that each step can be completed efficiently and accurately. Especially when bidirectional punching and bottom punching are performed simultaneously, the production efficiency can be greatly improved, the steps of multiple manual operations can be reduced, thereby reducing errors and improving the stability of the production line.

[0046] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
