Description

Technical Field

[0001] This invention relates to the field of metal processing, and in particular to an automated integrated workstation for punching and bending parts. Background Technology

[0002] In the field of metal sheet and structural component processing, punching and bending are two of the most common and critical forming processes. Traditional processing mode usually uses separate punching and bending machines to complete these two processes. The workpiece needs to be transferred, repositioned and clamped between the two machines. This not only leads to a longer production cycle and an increased floor space, but also introduces cumulative errors due to repeated positioning, affecting processing accuracy and product consistency.

[0003] To improve efficiency, traditional processing employs the development of composite machine tools that combine punching and bending functions. However, the function switching efficiency of composite machine tools is low. Most equipment requires manual or semi-automatic replacement of punches, dies, or entire tool assemblies, involving cumbersome operations such as bolt tightening and fixture adjustment, which is time-consuming and labor-intensive. This cannot meet the stringent requirements of modern automated production lines for rapid changeover, making it difficult to effectively improve equipment utilization. At the same time, processing flexibility is limited. Simple functional stacking often comes at the cost of process adaptability. Many integrated equipment have fixed worktables or only limited translation functions, making it impossible to achieve flexible adjustment of workpieces at multiple angles and directions during processing. This makes the equipment inadequate when performing complex bending, thus losing the flexibility of a single-function bending machine and resulting in a narrow application range after functional integration. Summary of the Invention

[0004] The main objective of this invention is to provide an automated integrated workstation for punching and bending parts, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An automated integrated workstation for punching and bending parts includes a fixed mounting frame. A cylinder mounting frame is fixedly mounted on the upper front end of the fixed mounting frame. A stamping cylinder is fixedly mounted on the upper end of the cylinder mounting frame. A stamping rod is fixedly mounted on the lower end of the piston rod of the cylinder mounting frame. A pressing connector is fixedly mounted on the lower end of the stamping rod. A switching punch structure is fixedly mounted on the front end of the fixed mounting frame below the cylinder mounting frame. A worktable mounting plate is fixedly mounted on the upper front end of the fixed mounting frame. A rotating base is fixedly mounted at the center of the worktable mounting plate. A rotating motor is fixedly mounted on the lower end of the rotating base. A transverse sliding base plate is movably mounted on the upper end of the transverse sliding base plate. An adjusting screw is movably mounted on the upper end of the transverse sliding base plate. An adjusting motor is fixedly mounted on the rear end of the transverse sliding base plate. A worktable structure is provided on the upper end of the transverse sliding base plate outside the adjusting motor.

[0007] As a further embodiment of the present invention, the switching punch structure includes a cylinder mounting bracket, a switching cylinder, a snap ring, a magnetic mounting head, a punching head, and a bending head. The cylinder mounting bracket is fixedly mounted at the front end of the fixed mounting bracket, the two switching cylinders are fixedly mounted at the rear end of the cylinder mounting bracket, the two snap rings are respectively fixedly mounted at the front end of the piston rods of the two switching cylinders, the two magnetic mounting heads are respectively inserted into the snap rings, and the punching head and the bending head are respectively welded to the lower end of the magnetic mounting head.

[0008] As a further embodiment of the present invention, the magnetic mounting head is inserted into the snap ring from bottom to top and connected by magnetic attraction. The punching head is located above the bending head. When the switching cylinder is running, it drives the snap ring and the magnetic mounting head to move back and forth.

[0009] As a further embodiment of the present invention, the stamping rod penetrates the cylinder mounting bracket. When the stamping cylinder is running, the stamping rod is driven to move downward, and the pressing connector is inserted from top to bottom into the magnetic mounting head for magnetic connection and to drive it to move downward.

[0010] As a further embodiment of the present invention, the transverse base plate is located above the workbench mounting plate, and the shaft of the rotating motor passes through the rotating base and is fixedly connected to the transverse base plate.

[0011] As a further embodiment of the present invention, the workbench structure includes a workbench base, a slider, a guide sleeve, an angle switching motor, a switching connecting plate, and a punching and bending workbench. The workbench base is located above the transverse base plate, the slider is fixedly installed at the lower end of the workbench base, two guide sleeves are fixedly installed on both sides of the workbench base, the angle switching motor is fixedly installed on one side of the workbench base and located above the guide sleeve, the switching connecting plate is movably installed on the inner side of the workbench base, and the punching and bending workbench is fixedly installed at the upper end of the switching connecting plate.

[0012] As a further embodiment of the present invention, the punching and bending workbench is located below the punching head and the bending head. The shaft of the angle switching motor passes through the workbench base and is fixedly connected to the switching connecting plate. The adjusting screw passes through the workbench base and is threadedly connected to it. The shaft of the adjusting motor and the end of the adjusting screw are fixedly connected by a coupling.

[0013] As a further embodiment of the present invention, guide rails are fixedly installed on both sides of the upper end of the transverse base plate, the slider is slidably connected to the upper end of the guide rail, and the worktable base moves back and forth around the guide rail via the slider.

[0014] As a further embodiment of the present invention, two guide rods are fixedly installed at the upper end of the transverse base plate above the guide rail, and the guide rods pass through the guide sleeve and are slidably connected to it.

[0015] As a further embodiment of the present invention, support feet are fixedly installed at the four corners of the lower end of the fixed mounting bracket, and the four support feet are arranged in parallel.

[0016] Compared with the prior art, the present invention has the following beneficial effects: By setting a unique switching punch structure, the punching and bending processes are integrated into one device. The switching cylinder drives the snap ring and magnetic mounting head to move back and forth. With the magnetic attraction and separation of the downward pressing joint at the end of the stamping rod, the switching between the punching head and the bending head can be carried out quickly and automatically. This eliminates the time spent changing molds or transferring workpieces in traditional processing. It not only increases the utilization rate of individual equipment, but also significantly improves processing efficiency. Furthermore, the magnetic mounting head is magnetically connected to the snap ring and the downward pressing joint. Combined with the stepped structure design, it ensures the reliability and accuracy of the tool's rapid docking and separation. At the same time, when the magnetic insertion structure changes the corresponding punching head and bending head, there is no need for manual intervention to disassemble or assemble bolts or clamps. The traditional time-consuming and labor-intensive mold changing process is compressed into an instantaneous action of pneumatic and magnetic attraction. This facilitates the replacement of independent modules, greatly improves the production cycle and equipment utilization rate, and significantly reduces the difficulty of operation, maintenance time and labor costs during maintenance.

[0017] The worktable structure has multiple degrees of freedom for adjustment. When rotating horizontally, the entire transverse base plate and the upper worktable can rotate horizontally by a rotating motor to change the processing orientation. When moving forward and backward, the adjusting motor drives the adjusting screw to move the worktable base along the guide rail to accurately position the workpiece. When rotating at an angle, the angle switching motor drives the switching connecting plate to tilt the punching and bending worktable itself at a specific angle. This multi-directional coordinated adjustment capability effectively solves the problem of processing monotony that may result from functional integration, ensuring that bending processing with different requirements can be performed. Moreover, after integrating punching and bending functions, the equipment not only does not sacrifice flexibility, but can also better adapt to bending process requirements at different angles and positions, preventing the limitation of complex processing capabilities caused by functional integration.

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-6 As shown, a fully automated workstation for punching and bending parts is provided. Please refer to it carefully. Figures 1-6 The system includes a fixed mounting bracket 1, a cylinder mounting bracket 3 fixedly mounted on the upper front end of the fixed mounting bracket 1, a stamping cylinder 4 fixedly mounted on the upper end of the cylinder mounting bracket 3, a stamping rod 5 fixedly mounted on the lower end of the piston rod of the cylinder mounting bracket 3, a pressing connector 6 fixedly mounted on the lower end of the stamping rod 5, a switching punch structure 7 fixedly mounted on the front end of the fixed mounting bracket 1 below the cylinder mounting bracket 3, a workbench mounting plate 14 fixedly mounted on the upper front end of the fixed mounting bracket 1, a rotating base 15 fixedly mounted on the center of the workbench mounting plate 14, a rotating motor 16 fixedly mounted on the lower end of the rotating base 15, a transverse base plate 17 movably mounted on the upper end of the rotating base 15, an adjusting screw 20 movably mounted on the upper end of the transverse base plate 17, an adjusting motor 19 fixedly mounted on the rear end of the transverse base plate 17, and a workbench structure 22 located outside the adjusting motor 19 on the upper end of the transverse base plate 17.

[0027] Please refer to this carefully. Figures 1-3The switching punch structure 7 includes a cylinder mounting bracket 8, a switching cylinder 9, a snap ring 10, a magnetic mounting head 11, a punching head 12, and a bending head 13. The cylinder mounting bracket 8 is fixedly mounted at the front end of the fixed mounting bracket 1. The two switching cylinders 9 are fixedly mounted at the rear end of the cylinder mounting bracket 8. The two snap rings 10 are respectively fixedly mounted at the front end of the piston rod of the two switching cylinders 9. The two magnetic mounting heads 11 are respectively inserted into the snap rings 10. The punching head 12 and the bending head 13 are respectively welded to the lower end of the magnetic mounting head 11.

[0028] Please refer to this carefully. Figures 1-3 The magnetic mounting head 11 is inserted into the snap ring 10 from bottom to top and connected by magnetic attraction. The punching head 12 is located above the bending head 13. When the switching cylinder 9 is running, it drives the snap ring 10 and the magnetic mounting head 11 to move back and forth.

[0029] Please refer to this carefully. Figures 1-3 The stamping rod 5 passes through the cylinder mounting bracket 3. When the stamping cylinder 4 is running, it drives the stamping rod 5 to move downward. The pressing connector 6 is inserted from top to bottom into the magnetic mounting head 11 for magnetic attraction and drives it to move downward.

[0030] Specifically, a workpiece is placed above the punching and bending worktable 28. Based on the punching or bending requirements of the workpiece, the switching cylinder 9 corresponding to the punching head 12 and bending head 13 is operated. This causes the switching cylinder 9 to move the drive snap ring 10 and magnetic mounting head 11 forward and extend them. Therefore, the punching head 12 or bending head 13 moves to below the pressing connector 6. The stamping cylinder 4 operates, driving the stamping rod 5 and the pressing connector 6 downward. Then, the pressing connector 6 first passes through the snap ring 10 and inserts into the magnetic mounting head 11. Next, the magnetic mounting head 11 pushes out of the snap ring 10 and connects magnetically, finally pressing the connector 6... The punching head 12 or bending head 13 below the magnetic mounting head 11 moves rapidly downward to punch or bend the workpiece on the punching and bending worktable 28. When the punching rod 5 and the lower pressing connector 6 rise, the magnetic mounting head 11 is inserted into the snap ring 10 from bottom to top. The inner diameter of the top of the snap ring 10 and the outer diameter of the magnetic mounting head 11 are set in a stepped shape, so the magnetic mounting head 11 cannot be disengaged from the top of the snap ring 10, causing the lower pressing connector 6 to separate from the magnetic mounting head 11. Then the switching cylinder 9 can run again to replace the punching head 12 or bending head 13, realizing the dual function of punching or bending.

[0031] Please refer to this carefully. Figure 4 and Figure 5 The transverse base plate 17 is located above the workbench mounting plate 14, and the shaft of the rotating motor 16 passes through the rotating base 15 and is fixedly connected to the transverse base plate 17.

[0032] Specifically, the operation of the rotating motor 16 drives the transverse base plate 17 to rotate above the rotating base 15, changing the overall processing orientation of the punching and bending worktable 28.

[0033] Please refer to this carefully. Figures 4-6 The workbench structure 22 includes a workbench base 23, a slider 24, a guide sleeve 25, an angle switching motor 26, a switching connecting plate 27, and a punching and bending workbench 28. The workbench base 23 is located above the transverse base plate 17. The slider 24 is fixedly installed at the lower end of the workbench base 23. Two guide sleeves 25 are fixedly installed on both sides of the workbench base 23. The angle switching motor 26 is fixedly installed on one side of the workbench base 23 and located above the guide sleeves 25. The switching connecting plate 27 is movably installed on the inner side of the workbench base 23. The punching and bending workbench 28 is fixedly installed on the upper end of the switching connecting plate 27.

[0034] Please refer to this carefully. Figures 4-6 The punching and bending worktable 28 is located below the punching head 12 and the bending head 13. The shaft of the angle switching motor 26 passes through the worktable base 23 and is fixedly connected to the switching connecting plate 27. The adjusting screw 20 passes through the worktable base 23 and is threadedly connected to it. The shaft of the adjusting motor 19 is fixedly connected to the end of the adjusting screw 20 through a coupling.

[0035] Please refer to this carefully. Figures 4-6 Guide rails 18 are fixedly installed on both sides of the upper end of the transverse base plate 17. The slider 24 is slidably connected to the upper end of the guide rail 18. The worktable base 23 moves back and forth around the guide rail 18 through the slider 24.

[0036] Please refer to this carefully. Figures 4-6 Two guide rods 21 are fixedly installed on the upper end of the transverse base plate 17 above the guide rail 18. The guide rods 21 pass through the guide sleeve 25 and are slidably connected to it.

[0037] Specifically, the operation of the adjusting motor 19 drives the adjusting screw 20 to rotate. The adjusting screw 20 moves back and forth through a threaded connection with the worktable base 23, changing the front and rear processing position of the punching and bending worktable 28. The operation of the angle switching motor 26 drives the switching connecting plate 27 to rotate within the worktable base 23, directly changing the processing angle of the punching and bending worktable 28. This allows for simultaneous adjustment of the processing orientation and angle to meet different processing requirements during bending.

[0038] Please refer to this carefully. Figure 1 and Figure 2 Supporting feet 2 are fixedly installed at the four corners of the lower end of the fixed mounting bracket 1, and the four supporting feet 2 are arranged in parallel.
