Description

Technical Field

[0001] The invention relates to the technical field of processing special-shaped connectors of display racks, and more specifically, to punching equipment and a punching process thereof for processing special-shaped connectors of display racks. Background Art

[0002] Display stand connectors are components used to connect the various parts of the display stand together. They play a key role in ensuring the stability and aesthetics of the display stand structure. Special-shaped connectors refer to those connectors whose shapes and structures are different from conventional standard parts. They are usually customized according to specific application needs and design requirements. When processing special-shaped connectors, holes need to be punched on the connectors to facilitate the subsequent installation of bolts and nuts.

[0003] During processing, the existing punching equipment needs to process each component of the connector separately, and then the staff will assemble the punched components. In order to improve efficiency, the staff has improved the existing punching equipment, that is, the components are continuously conveyed by a screw feeder, and then the conveyed components are punched through a punching mechanism.

[0004] However, since the workpiece is composed of multiple parts, if they are processed separately and then assembled, the parts are easily deformed during transportation and punching. If they are punched directly, it is easy to cause poor punching accuracy of the parts, which may cause the workpiece to be unusable during subsequent assembly. Summary of the invention

[0007] The first positioning assembly includes a fixed seat installed on the top of the workbench and an L-shaped plate installed on the top of the fixed seat. A positioning cylinder is installed on one side of the L-shaped plate. The piston rod of the positioning cylinder passes through the L-shaped plate and is connected to the first positioning column.

[0008] The clamping assembly comprises a clamping block installed in the middle of the top surface of the workbench and an adjusting mechanism arranged behind the clamping block.

[0010] By adopting the above technical solution, the workpiece is arranged between two adjacent limiting plates, and a placement groove is formed between the adjacent limiting plates. A workpiece is placed in the placement groove, and the placement direction of the workpiece is convenient for subsequent processing operations.

[0011] The present invention is further configured as follows: the punching assembly includes a support frame installed on one side of the top of the workbench and a first punching cylinder installed on the top of the support frame, the piston rod of the first punching cylinder extends vertically downward to the interior of the adjustment mechanism and is connected to a first punching knife, and the first punching knife is located above the first positioning assembly.

[0012] By adopting the above technical solution, the first punching cylinder is used to push the first punching knife to move up and down, and when the first punching knife moves downward, a punching operation is performed on the workpiece clamped on the clamping assembly.

[0013] The present invention is further configured as follows: the adjustment mechanism includes two positioning seats installed on the top of the workbench, the two positioning seats are located on both sides of the Z-shaped plate, one side of the positioning seat is connected to a mounting plate, the top of the mounting plate is slidably connected to a slider, the top of the slider is vertically installed with a first clamping cylinder, and the two output ends of the top of the first clamping cylinder are connected to clamping claws.

[0014] The present invention is further configured as follows: the adjustment mechanism also includes a Z-shaped plate installed on the top of the workbench and a bidirectional cylinder installed on the top of the Z-shaped plate, the two piston rods of the bidirectional cylinder are both connected to a connecting plate, and the two connecting plates are respectively connected to two sliders.

[0015] By adopting the above technical solution, the clamping block performs preliminary positioning of the workpiece clamped by the transfer assembly, and the adjustment mechanism performs fine positioning of the workpiece after preliminary positioning. It can not only clamp the assembled workpiece, but also adjust the angle of the assembled workpiece, which greatly improves the accuracy and efficiency of workpiece punching.

[0016] The two-way cylinder drives the two connecting plates closer to each other, causing the two sliders and the corresponding first clamping cylinder to move to the outer wall of the workpiece, and the first clamping cylinder is in contact with the side wall of the clamping block, and then the two matching jaws are used to support the workpiece, causing the two groups of swinging parts on the workpiece to swing to the same horizontal plane, and then the first clamping cylinder is used to drive the corresponding two clamping jaws to clamp the workpiece, causing the two groups of swinging parts of the workpiece to approach each other to complete the docking, and then the piston rod of the two-way cylinder is extended again, and the two piston rods of the two-way cylinder push the two connecting plates and the sliders away from each other, and the two sliders drive the corresponding first clamping cylinder and the clamping jaws to move along the extension direction of the workpiece, causing the swinging part of the workpiece to be straightened and adjusted.

[0017] The present invention is further configured as follows: the transfer assembly includes two first electric slide rails installed on the top of the workbench and a gantry slidably connected to the top of the two first electric slide rails, a second electric slide rail is horizontally installed on one side of the gantry, a third electric slide rail is slidably connected to one side of the second electric slide rail, the third electric slide rail is vertically arranged, a slide seat is slidably connected to one side of the third electric slide rail, the bottom of the slide seat is connected to a base plate, and two second clamping cylinders are installed at the bottom of the base plate.

[0018] The present invention is further configured as follows: four driven wheels are connected at the four corners of the bottom of the base plate, the outer side walls of the four driven wheels are transmission-connected with a transmission belt, the bottom of the base plate is symmetrically connected to two guide rails, the bottoms of the two guide rails are both slidably connected to a third clamping cylinder, the third clamping cylinder is connected to the transmission belt, the bottom of the base plate is rotatably connected to an electric wheel, and the outer side wall of the electric wheel is embedded with the outer wall of the transmission belt.

[0019] By adopting the above technical scheme, the electric wheel is used to drive the transmission belt to transmit on the outer walls of the four driven wheels, and the transmission belt drives the two third clamping cylinders to move synchronously, thereby adjusting the distance between the third clamping cylinder and the corresponding second clamping cylinder. When the third clamping cylinder clamps the unprocessed workpiece, the distance between the third clamping cylinder and the corresponding second clamping cylinder is reduced, while the distance between the other third clamping cylinder and the corresponding second clamping cylinder is increased. When the workpiece is transported on the conveyor belt mechanism, it is easy to deviate due to the vibration of the conveyor belt mechanism. The workpiece is clamped by the third clamping cylinder with a smaller distance and the corresponding second clamping cylinder to avoid the situation of being unable to clamp. When the workpiece is unloaded from the clamping block, since the position of the workpiece is standard, the workpiece is clamped by the third clamping cylinder with a larger distance and the corresponding second clamping cylinder to complete the unloading operation. The loading and unloading operations are performed simultaneously through the transfer assembly, which greatly improves the efficiency of unloading and loading of the workpiece.

[0020] The present invention is further configured as follows: the second positioning assembly includes a positioning plate installed on the top of the workbench and located on one side of one of the positioning seats, a driving cylinder is horizontally installed on one side of the positioning plate, the piston rod of the driving cylinder is connected to a second positioning column, and the second positioning column is arranged toward the clamping assembly.

[0021] The present invention is further configured as follows: a fixing plate is horizontally installed on one side of the positioning plate away from the driving cylinder, a second punching cylinder is vertically installed on the bottom of the fixing plate, a piston rod of the second punching cylinder vertically penetrates the fixing plate upward and is connected to a second punching knife.

[0022] By adopting the above technical solution, the driving cylinder pushes the second positioning column to be inserted into the hole at the other end of the workpiece, and the second positioning column, the first positioning column and the clamping block cooperate to achieve precise positioning of the workpiece. When the workpiece is positioned, the first punching cylinder pushes the first punching tool to move vertically downward, and the second punching cylinder pushes the second punching tool to move upward. In this state, the second punching tool and the first punching tool cooperate to perform punching operation on the workpiece after precise positioning.

[0023] The punching process for processing the special-shaped connector of the display rack, according to the punching equipment for processing the special-shaped connector of the display rack described above, comprises the following steps:

[0024] S1. The staff places the workpiece to be processed on the top of the conveying component, and the conveying component feeds the workpiece toward the transfer component;

[0025] S2, then the workpiece conveyed by the conveying component is grabbed by the transfer component, and the workpiece is transferred and placed on the top of the clamping block, the workpiece is positioned and clamped by the clamping block, and then the workpiece on the clamping block is adjusted by the adjustment mechanism;

[0026] S3, then use two matching clamps to support the workpiece, so that the two sets of swinging parts on the workpiece swing to the same horizontal plane, then use the first clamping cylinder to drive the corresponding two clamps to clamp the workpiece, so that the two sets of swinging parts of the workpiece are close to each other to complete the docking, then use the piston rod of the two-way cylinder to extend again, the two piston rods of the two-way cylinder push the two connecting plates and the slider away from each other, and the two sliders drive the corresponding first clamping cylinder and the clamp to move along the extension direction of the workpiece, so that the swinging part of the workpiece is straightened and adjusted;

[0027] S4. After the workpiece is adjusted, the positioning cylinder is used to push the first positioning column to move on the top of the fixed seat, so that the first positioning column is inserted into the interior of the workpiece for positioning.

[0028] S5. Then, the second positioning component is used to position the other end of the workpiece to ensure the accuracy of the workpiece during punching. After that, the second positioning component and the punching component cooperate to complete the punching of the workpiece. After the punching of the workpiece is completed, the transfer component removes the punched workpiece and transfers the unpunched workpiece to the position of the clamping block, and then punches the next workpiece.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] (1) By setting a clamping block and an adjusting mechanism, the clamping block performs preliminary positioning on the workpiece clamped by the transfer assembly, and the adjusting mechanism performs fine positioning on the workpiece after preliminary positioning. It can not only clamp the assembled workpiece, but also adjust the angle of the assembled workpiece, which greatly improves the accuracy and efficiency of workpiece punching.

[0031] (2) The two-way cylinder drives the two connecting plates to approach each other, causing the two sliders and the corresponding first clamping cylinder to move to the outer wall of the workpiece, and the first clamping cylinder fits against the side wall of the clamping block. Then, the two matching clamping jaws are used to support the workpiece, causing the two sets of swinging parts on the workpiece to swing to the same horizontal plane. Then, the first clamping cylinder is used to drive the corresponding two clamping jaws to clamp the workpiece, causing the two sets of swinging parts of the workpiece to approach each other to complete the docking. Then, the piston rod of the two-way cylinder is extended again. The two piston rods of the two-way cylinder push the two connecting plates and the sliders away from each other. The two sliders drive the corresponding first clamping cylinder and the clamping jaws to move along the extension direction of the workpiece, causing the swinging part of the workpiece to be straightened and adjusted.

[0032] (3) By setting the first positioning assembly and the second positioning assembly, after the workpiece is adjusted, the positioning cylinder is used to push the first positioning column to move on the top of the fixed seat, so that the first positioning column is inserted into the interior of the workpiece for one positioning, and the driving cylinder pushes the second positioning column to insert into the hole at the other end of the workpiece. The second positioning column, the first positioning column and the clamping block cooperate to achieve precise positioning of the workpiece.

[0033] (4) After the workpiece is positioned, the first punching cylinder pushes the first punching tool to move vertically downward, and the second punching cylinder pushes the second punching tool to move upward. In this state, the second punching tool and the first punching tool cooperate to perform punching operation on the workpiece after precise positioning, and the complete punching operation can be achieved without the need for the staff to manually adjust the angle.

[0054] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0055] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0056] See also Figure 1-11 , the present invention provides the following technical solutions:

[0057] Example 1, see Figure 1 The punching equipment for processing special-shaped connectors of display racks includes a workbench 1, a conveying assembly 2 arranged on one side of the workbench 1, a workpiece 8 is arranged on the top of the conveying assembly 2, the workbench 1 carries one end of the conveying assembly 2, and the conveying assembly 2 is used to convey the workpiece 8. The specific structure of the conveying assembly 2 is as follows:

[0058] See also Figure 1 , Figure 2 and Fig.11 The conveying assembly 2 includes a carrying plate 22 connected to the front of the workbench 1 and a support leg 21 connected to the bottom of the carrying plate 22. A conveyor belt mechanism 23 is installed on the top of the carrying plate 22. The conveyor belt of the conveyor belt mechanism 23 is equidistantly connected to the outside of the conveyor belt. The limit plates 24 are equidistantly connected. The workpiece 8 is arranged between two adjacent limit plates 24. A placement groove is formed between the adjacent limit plates 24. A workpiece 8 is placed in the placement groove. The placement direction of the workpiece 8 is convenient for subsequent processing operations.

[0059] See also Figure 1 and Figure 4 A transfer assembly 6 is installed on the top of the workbench 1, and a clamping assembly 5 is installed on the top of the workbench 1. The transfer assembly 6 is used to clamp and transport the workpiece 8 transported by the conveyor belt mechanism 23. The workpiece 8 is transported and placed on the clamping assembly 5 to wait for the punching operation. The specific structure of the transfer assembly 6 is as follows:

[0060] See also Figure 1 and Figure 4 The transfer assembly 6 includes two first electric slide rails 61 installed on the top of the workbench 1 and a gantry 62 slidably connected to the top of the two first electric slide rails 61, a second electric slide rail 63 is horizontally installed on one side of the gantry 62, a third electric slide rail 64 is slidably connected to one side of the second electric slide rail 63, the third electric slide rail 64 is vertically arranged, a slide seat 65 is slidably connected to one side of the third electric slide rail 64, the bottom of the slide seat 65 is connected to a base plate 66, and two second clamping cylinders 601 are installed at the bottom of the base plate 66.

[0061] The gantry 62, the second electric slide 63 and the third electric slide 64 are driven to move synchronously by the first electric slide 61. At the same time, the third electric slide 64 is driven to move by the second electric slide 63, thereby adjusting the position of the third electric slide 64. When the third electric slide 64 moves to the front end position in the conveying direction of the conveyor belt mechanism 23, the third electric slide 64 drives the slide seat 65 and the bottom plate 66 to move downward as a whole. The second clamping cylinder 601 and the third clamping cylinder 603 cooperate to grab the workpiece 8 transported on the conveyor belt mechanism 23. The workpiece 8 is grabbed and transported to the top of the clamping assembly 5 to wait for punching operation.

[0062] See also Figure 4 and Figure 5 A punching assembly 4 is installed on the top of the workbench 1. The punching assembly 4 is used to punch the clamped workpiece 8. The specific structure of the punching assembly 4 is as follows:

[0063] See also Figure 4 and Figure 5 In this embodiment, the punching assembly 4 includes a support frame 41 installed on one side of the top of the workbench 1 and a first punching cylinder 42 installed on the top of the support frame 41. The piston rod of the first punching cylinder 42 extends vertically downward to the inside of the adjusting mechanism 51 and is connected to a first punching knife 43. The first punching knife 43 is located above the first positioning assembly 3. The first punching cylinder 42 is used to push the first punching knife 43 to move up and down. When the first punching knife 43 moves downward, it punches the workpiece 8 clamped on the clamping assembly 5, and then unloads the material through the transfer assembly 6. The staff manually adjusts the angle and then re-places it on the conveyor belt mechanism 23 for feeding, and then uses the punching assembly 4 to punch the other end of the workpiece 8.

[0064] In the second embodiment, since the workpiece 8 is composed of multiple parts, if they are processed separately and then assembled, the parts are likely to be deformed during transportation and punching. If they are punched directly, it is easy to cause poor punching accuracy of the parts, which may easily make the workpiece 8 unusable during subsequent assembly.

[0065] See also Figure 1 , Figure 4 , Figure 5 and Figure 7 To this end, a first positioning component 3 and a second positioning component 7 are installed on the top of the workbench 1. A clamping component 5 is also installed on the top of the workbench 1. The first positioning component 3 is located directly below the punching component 4. The clamping component 5 and the second positioning component 7 are both located between the first positioning component 3 and the transfer component 6. The second positioning component 7 is located below the transfer component 6.

[0066] The clamping assembly 5 is used to clamp and adjust the workpiece 8, and then the first positioning assembly 3 and the second positioning assembly 7 cooperate to position the assembled workpiece 8, thereby ensuring the docking accuracy of the workpiece 8. Then, one end of the workpiece 8 is punched by the punching assembly 4, and the other end of the workpiece 8 is punched by the second positioning assembly 7, so that the workpiece 8 can be punched directly at both ends without being transported, which greatly improves the accuracy and efficiency of the punching of the workpiece 8. The specific structure of the clamping assembly 5 is as follows:

[0067] See also Figure 7 The clamping assembly 5 includes a clamping block 52 installed in the middle of the top surface of the workbench 1 and an adjusting mechanism 51 arranged behind the clamping block 52. The clamping block 52 is used to perform preliminary positioning of the workpiece 8 clamped by the transfer assembly 6, and the adjusting mechanism 51 is used to perform fine positioning of the workpiece 8 after the preliminary positioning. The specific structure of the adjusting mechanism 51 is as follows:

[0068] See also Figure 7-Figure 9 The adjusting mechanism 51 includes a Z-shaped plate 511 installed on the top of the workbench 1 and a bidirectional cylinder 512 installed on the top of the Z-shaped plate 511. The two piston rods of the bidirectional cylinder 512 are connected to a connecting plate 513. The bidirectional cylinder 512 is used to drive the two connecting plates 513 to move closer to or away from each other. The adjusting mechanism 51 includes two positioning seats 514 installed on the top of the workbench 1. The two positioning seats 514 are located on both sides of the Z-shaped plate 511. One side of the positioning seat 514 is connected to a mounting plate 515. The top of the mounting plate 515 is slidably connected to a slider 5 16. The two connecting plates 513 are respectively connected to the two sliding blocks 516. When the two connecting plates 513 approach or move away from each other, the corresponding sliding blocks 516 are driven to slide on the corresponding mounting plates 515. A first clamping cylinder 517 is vertically installed on the top of the sliding block 516. The two output ends of the top of the first clamping cylinder 517 are both connected to the clamping claws 518. When the sliding block 516 drives the corresponding first clamping cylinder 517 and the clamping claw 518 to move synchronously during the sliding process, the first clamping cylinder 517 is used to drive the corresponding two clamping claws 518 to approach or move away from each other.

[0069] Specifically, the bidirectional cylinder 512 drives the two connecting plates 513 to approach each other, so that the two sliders 516 and the corresponding first clamping cylinder 517 move to the outer wall of the workpiece 8, and the first clamping cylinder 517 fits with the side wall of the clamping block 52, and then the two matching clamping claws 518 are used to support the workpiece 8, so that the two sets of swinging parts on the workpiece 8 swing to the same horizontal plane, and then the first clamping cylinder 517 drives the corresponding two clamping claws 518 to clamp the workpiece 8, so that the two sides of the workpiece 8 are The swing parts of the two groups are brought close to each other to complete the docking, and then the piston rod of the two-way cylinder 512 is extended again. The two piston rods of the two-way cylinder 512 push the two connecting plates 513 and the slider 516 away from each other, and the two sliders 516 drive the corresponding first clamping cylinder 517 and the clamping claw 518 to move along the extension direction of the workpiece 8, so that the swing part of the workpiece 8 is straightened and adjusted, and the concave and convex wedging is set at the relative position of the two corresponding swing parts on the workpiece 8, and the concave and convex wedging is used to assist in positioning the workpiece 8.

[0070] After the workpiece 8 is adjusted, the first positioning assembly 3 and the second positioning assembly 7 are used for precise positioning. The specific structure of the first positioning assembly 3 is as follows:

[0071] See also Figure 6 The first positioning assembly 3 includes a fixed seat 31 installed on the top of the workbench 1 and an L-shaped plate 32 installed on the top of the fixed seat 31. A positioning cylinder 33 is installed on one side of the L-shaped plate 32. The piston rod of the positioning cylinder 33 passes through the L-shaped plate 32 and is connected to a first positioning column 34. After the workpiece 8 is adjusted, the positioning cylinder 33 is used to push the first positioning column 34 to move on the top of the fixed seat 31, so that the first positioning column 34 is inserted into the interior of the workpiece 8 for positioning.

[0072] The specific structure of the second positioning component 7 is as follows:

[0073] See also Figure 7 The second positioning assembly 7 includes a positioning plate 71 installed on the top of the workbench 1 and located on one side of one of the positioning seats 514. A driving cylinder 72 is horizontally installed on one side of the positioning plate 71. The piston rod of the driving cylinder 72 is connected to a second positioning column 73. The second positioning column 73 is set toward the clamping assembly 5. The driving cylinder 72 pushes the second positioning column 73 to insert into the hole at the other end of the workpiece 8. The second positioning column 73, the first positioning column 34 and the clamping block 52 cooperate to achieve precise positioning of the workpiece 8.

[0074] See also Figure 7A fixing plate 74 is horizontally installed on one side of the positioning plate 71 away from the driving cylinder 72, and a second punching cylinder 76 is vertically installed on the bottom of the fixing plate 74. The piston rod of the second punching cylinder 76 vertically penetrates the fixing plate 74 upward and is connected to a second punching knife 75. When the workpiece 8 is positioned, the first punching cylinder 42 pushes the first punching knife 43 to move vertically downward, and the second punching cylinder 76 pushes the second punching knife 75 upward. In this state, the second punching knife 75 and the first punching knife 43 cooperate to perform punching operation on the workpiece 8 after precise positioning of the workpiece 8.

[0075] Example 3, see Figure 4 and Fig.10 After the punching of the workpiece 8 is completed, if the workpiece 8 is unloaded through the transfer assembly 6 and then loaded onto the workpiece 8 on the conveyor belt mechanism 23, this process is relatively cumbersome. For this reason, four driven wheels 67 are connected at the four corners of the bottom of the bottom plate 66, and the outer side walls of the four driven wheels 67 are connected to the transmission belt 68 for transmission. The bottom of the bottom plate 66 is symmetrically connected to two guide rails 602, and the bottoms of the two guide rails 602 are both slidably connected to the third clamping cylinder 603, and the third clamping cylinder 603 is connected to the transmission belt 68. The bottom of the bottom plate 66 is rotatably connected to an electric wheel 69, and the outer side wall of the electric wheel 69 is embedded with the outer wall of the transmission belt 68. The electric wheel 69 is used to drive the transmission belt 68 to transmit on the outer walls of the four driven wheels 67, and the transmission belt 68 drives the two third clamping cylinders 603 to move synchronously, thereby adjusting the third clamping cylinder 603 is relative to the spacing between the corresponding second clamping cylinders 601. When the third clamping cylinder 603 clamps the unprocessed workpiece 8, the spacing between the third clamping cylinder 603 and the corresponding second clamping cylinder 601 is reduced, while the spacing between the other third clamping cylinder 603 and the corresponding second clamping cylinder 601 is increased. When the workpiece 8 is transported on the conveyor belt mechanism 23, it is easy to be offset due to the vibration of the conveyor belt mechanism 23. The third clamping cylinder 603 with a smaller spacing cooperates with the corresponding second clamping cylinder 601 to clamp the workpiece 8 to avoid the situation where it cannot be clamped. When the workpiece 8 is unloaded from the clamping block 52, since the position of the workpiece 8 is standard, the third clamping cylinder 603 with a larger spacing cooperates with the corresponding second clamping cylinder 601 to clamp the workpiece 8, thereby completing the unloading operation.

[0076] Furthermore, the loading and unloading operations are performed simultaneously by the transfer assembly 6 , which greatly improves the loading and unloading efficiency of the workpiece 8 .

[0077] Embodiment 4, a punching process for processing special-shaped connectors of a display stand, according to the punching equipment for processing special-shaped connectors of a display stand, comprises the following steps:

[0078] S1. A worker places a workpiece 8 to be processed on the top of the conveying component 2, and the conveying component 2 feeds the workpiece 8 toward the transfer component 6.

[0079] More specific steps are:

[0080] S11, the staff places the workpiece 8 to be processed between the limit plates 24 on the top of the conveyor belt mechanism 23, and then the conveyor belt mechanism 23 drives the multiple limit plates 24 and the workpiece 8 to continuously feed in the direction of the transfer assembly 6.

[0081] S2. Then, the workpiece 8 transported by the conveying component 2 is grabbed by the transfer component 6, and the workpiece 8 is transferred and placed on the top of the clamping block 52. The workpiece 8 is positioned and clamped by the clamping block 52, and then the workpiece 8 on the clamping block 52 is adjusted by the adjustment mechanism 51.

[0082] More specific steps are:

[0083] S21. The gantry 62, the second electric slide 63 and the third electric slide 64 are driven to move synchronously by the first electric slide 61.

The two sliders 516 drive the corresponding first clamping cylinder 517 and the clamps 518 to move along the extension direction of the workpiece 8, causing the swinging parts of the workpiece 8 to be straightened and adjusted.

[0087] S4. After the workpiece 8 is aligned, the positioning cylinder 33 is used to push the first positioning column 34 to move on the top of the fixing seat 31, so that the first positioning column 34 is inserted into the interior of the workpiece 8 for positioning.

[0088] S5. Then, the second positioning component 7 is used to position the other end of the workpiece 8 to ensure the accuracy of the workpiece 8 during punching. After that, the second positioning component 7 and the punching component 4 cooperate to complete the punching of the workpiece 8. After the punching of the workpiece 8 is completed, the transfer component 6 removes the punched workpiece 8 and transfers the unpunched workpiece 8 to the position of the clamping block 52, and then punches the next workpiece 8.

[0089] More specific steps are:

[0090] S51, the driving cylinder 72 pushes the second positioning column 73 to insert into the hole at the other end of the workpiece 8, and the second positioning column 73, the first positioning column 34 and the clamping block 52 cooperate to achieve precise positioning of the workpiece 8. Then, the first punching cylinder 42 pushes the first punching tool 43 to move vertically downward, and the second punching cylinder 76 pushes the second punching tool 75 to move upward. In this state, the second punching tool 75 and the first punching tool 43 cooperate to perform punching operation on the workpiece 8 after precise positioning of the workpiece 8.

[0091] S52, then one of the second clamping cylinders 601 and the third clamping cylinder 603 cooperates to grab the workpiece 8 transported on the conveyor belt mechanism 23, and the other second clamping cylinder 601 and the third clamping cylinder 603 cooperate to grab the punched workpiece 8, and perform loading and unloading operations through the transfer assembly 6.
