Description

Technical Field

[0001] The present invention relates to the technical field of metal combination processing, and more particularly to a punching and shearing machine for office desk panel materials. Background Art

[0002] Intelligent punching and shearing machines have numerous applications in metal processing for office desk countertops, primarily due to their efficient, precise, and flexible metalworking capabilities. Primarily, they offer shearing, using cutting tools to intelligently and precisely cut sheet metal to the desired size and shape. Furthermore, they offer punching, creating holes of various shapes and sizes in sheet metal using a punch. This allows for combined mechanical functions and metal processing operations.

[0003] In existing public literature, Chinese patent publication number CN103817523A discloses a combined punching and shearing machine. This machine is connected to the motor end via a screw, which is threaded onto a connecting seat. The shear mechanism features I-beam and channel steel shearing devices on the left side, angle steel shearing devices on the right side, and flat steel shearing devices on the lower right side. This device has a simple structure, is driven by a motor, and provides sufficient shearing force. It does not require a hydraulic cylinder, thus preventing oil leakage and environmental pollution. It also features multi-station work capabilities, improving efficiency, reducing production costs, and conserving energy. However, this technology still presents the following challenges.

[0004] During the punching and shearing process of the office desk panel material, since the office desk panel material has multiple surfaces and multiple corner positions, the punching and shearing process needs to be performed one by one, and the office desk panel material after punching and shearing needs to be bent into grooves one by one on the side, and the holes at the bending positions need to be punched one by one. This results in that when the office desk panel material is subjected to combined metal processing, it is difficult to achieve synchronous punching and shearing of multiple corner positions of the office desk panel material, and it is difficult to achieve synchronous vertical bending of multiple surfaces of the office desk panel material, and it is also difficult to perform synchronous horizontal bending of the grooves on multiple surfaces of the office desk panel material, and it is difficult to achieve synchronous side groove punching operations on multiple surfaces of the office desk panel material. This leads to a significant decrease in the efficiency of the combined metal processing of the punching and shearing machine, so a office desk panel material punching and shearing machine is needed. Summary of the Invention

[0007] Preferably, a plurality of the pressure columns are arranged in a circular ring with equal spacing, and the cross-sectional shape of each of the bending plates is rectangular. The bending plate is slidably connected to the corner punching shears, and the outer walls of the bending plate and the outer walls of the corner punching shears are both smooth surfaces. The outer wall of the fixed punching shears is fixedly connected to a limit block, and the metal sheet is plugged into the limit block. The bottom end of each fixed punching shear is fixedly connected to a pillar, and a support frame is installed at the bottom end of the pillar, and a plurality of the pillars are fixedly connected to the support frame; the inner wall of the support frame is fixedly connected to a support column, and the top end of the support column is fixedly connected to a support plate, and a positioning plate is fixedly installed at the top end of the support plate, and the positioning plate is plugged into the inner wall of the office desk; the bottom end of the support column is fixedly connected to a mounting plate, and the mounting plate is fixedly connected to the socket frame.

[0008] When this technology is in use, the punching and shearing electric cylinder pushes the punching and shearing rod downward, the punching and shearing pressure sensor causes the pressure plate to move downward, and multiple corner punching scissors punch downward to shear the edge corners of the metal sheet. When the pressure value sensed by the punching and shearing pressure sensor is the same as the pressure value set by the controller, the punching and shearing electric cylinder is turned off by the controller. The linkage electric cylinder pushes the bending pressure sensor downward, the pressure sleeve drives multiple pressure columns to move downward synchronously, and the multiple pressure columns drive multiple bending plates to move downward synchronously, and the bending plates drive the extended portion of the upper surface of the metal sheet to bend downward by 90 degrees, so that the extended portion of the upper surface of the metal sheet fits on the side of the office desk. In this way, the extended portions of the multiple upper surfaces of the metal sheet are synchronously fitted to multiple side positions of the outer wall of the office desk according to the specified bending force.

[0009] Preferably, the multi-faceted lateral combined bending mechanism includes a punching electric cylinder arranged on one side of the linkage electric cylinder; a bending electric cylinder is provided on one side of the punching electric cylinder, and the punching electric cylinder and the bending electric cylinder are fixedly connected to the pressure sleeve ring, and the output end of the punching electric cylinder is fixedly connected to a lateral pressure sensor, and the bottom end of the lateral pressure sensor is fixedly connected to a connecting strip, and one end of the connecting strip is fixedly installed with an inner ring in a groove; the inner wall of the inner ring in the groove is fixedly connected with a plurality of pressing shafts, and the outer wall of each pressing shaft is rotatably connected with a sleeve rod, and the inner wall of the sleeve rod is rotatably connected with a push shaft away from the pressing shaft position, and one end of the push shaft is fixedly installed with a hinge block.

[0010] The lower surface of the hinge block is fixedly connected to a concave bead, one end of which is fixedly connected to a lateral bending strip. Both the lateral bending strip and the concave bead are slidably connected to the bending plate.

The output end of the punching cylinder is equipped with a multi-faceted synchronous combination punching assembly. Multiple pressure shafts are arranged in a circular ring with equal spacing, and the concave bead is slidably connected to the pressure ring.

[0011] When this technology is in use, the bending cylinder pushes the lateral pressure sensor downward, causing the connecting bar to simultaneously move the inner ring of the groove downward. The pressure shaft drives the top of the sleeve rod downward, and the push shaft drives the hinge block to the right. The concave pressure bar moves right along the inner wall of the sleeve frame. At the same time, the concave pressure bar causes the lateral bending bar to move rightward, and the lateral bending bar moves rightward along the upper surface of the bending plate, enabling the simultaneous horizontal bending of metal sheets on multiple sides of the desk.

[0012] Preferably, the multi-faceted synchronous combination punching assembly includes a punching pressure sensor fixedly arranged at the output end of the punching electric cylinder; the bottom end of the punching pressure sensor is fixedly connected to a linkage bar, and the bottom end of the linkage bar is welded with a groove outer ring, the inner wall of the groove outer ring is fixedly connected to multiple extrusion shafts, the outer wall of each extrusion shaft is rotatably connected to a sleeve rod, and the inner wall of the sleeve rod is rotatably connected to a push rod at a position away from the extrusion shaft; one end of the push rod is fixedly connected to a concave block, and one side of the concave block is fixedly connected to two punching tools, and both punching tools are slidably connected to the lateral bending bar; one side of the bending plate is fixedly connected to a guide sleeve plate, and the punching tool and the guide sleeve plate are slidably connected.

[0013] When this technology is in use, the punching cylinder pushes the punching pressure sensor downward, and the linkage bar causes the outer ring of the groove to move downward synchronously. The outer ring of the groove can also drive the multiple extrusion shafts to move downward synchronously. The bottom end of the sleeve rod drives the push rod to the right, and the concave block causes the two punching tools to move right synchronously.

[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention uses a multi-faceted synchronous punching and bending combination mechanism. The punching and shearing electric cylinder pushes the punching and shearing rod downward, the punching and shearing pressure sensor causes the pressure plate to move downward, the pressure plate drives the pressure ring to move downward, and multiple corner punching shears punch downward the edge corner positions of the metal sheet. When multiple corner punching shears have punched the metal sheet at the corner positions, the controller starts the linkage electric cylinder, the bending pressure sensor drives the pressure sleeve ring to move downward, and multiple pressure columns drive multiple bending plates to move downward synchronously, so that the extended parts of multiple upper surfaces of the metal sheet are simultaneously attached to multiple side positions of the outer wall of the office desk according to the specified bending force. In this way, multiple corner positions of the metal sheet can be synchronously punched and sheared, and multiple surfaces of the metal sheet can be synchronously bent vertically, thereby greatly improving the efficiency of the punching and shearing machine combination metal processing.

[0016] 2. The present invention utilizes a multi-faceted lateral combined bending mechanism. The bending electric cylinder pushes the lateral pressure sensor downward, the lateral pressure sensor drives the connecting strip downward, the pressure shaft drives the top end of the sleeve rod downward, and the sleeve rod drives the push shaft to move right, the hinge block drives the concave pressure strip to move right, and the concave pressure strip moves right along the inner wall of the sleeve frame plate. It can synchronously perform horizontal synchronous bending on the metal sheets on multiple sides of the office desk, and can perform horizontal synchronous bending processing on the groove body on multiple sides of the metal sheet, thereby greatly improving the efficiency of the punching and shearing machine combined metal processing.

[0017] 3. The present invention uses a multi-sided synchronous combination punching assembly. The punching electric cylinder pushes the punching pressure sensor downward, the punching pressure sensor drives the linkage bar downward, the extrusion shaft drives the top end of the sleeve rod downward, and the bottom end of the sleeve rod drives the push rod to move right. Both punching tools move right along the inner wall of the lateral bending strip. The punching tools inside the multiple lateral bending strips can synchronously punch the metal sheets on multiple surfaces of the outer wall of the office desk, and can synchronously realize side groove punching operations on multiple surfaces of the metal sheets, thereby greatly improving the efficiency of the combined metal processing of the punching and shearing machine.

[0018] According to the mutual influence of the above multiple functions, first, the multiple corner positions of the metal sheet can be synchronously punched and sheared, and the multiple surfaces of the metal sheet can be synchronously bent vertically. At the same time, the metal sheets on multiple sides of the office desk can be synchronously bent horizontally.

In summary, the multiple corner positions of the metal sheet can be synchronously punched and sheared, and the multiple surfaces of the metal sheet can be synchronously bent vertically. The multiple surfaces of the metal sheet can also be synchronously bent horizontally in the groove body. As well as the multiple surfaces of the metal sheet can be synchronously punched in the side groove, the efficiency of the metal processing of the punching and shearing machine combination can be greatly improved.

[0037] In this embodiment, as shown in the attached Figure 2 - Attachment Figure 7 As shown, the multi-faceted lateral combined bending mechanism includes a punching electric cylinder 25 arranged on one side of the linkage electric cylinder 8; a bending electric cylinder 26 is provided on one side of the punching electric cylinder 25, and the punching electric cylinder 25 and the bending electric cylinder 26 are both fixedly connected to the pressing ring 10, and the output end of the punching electric cylinder 25 is fixedly connected to a lateral pressure sensor 27, and the bottom end of the lateral pressure sensor 27 is fixedly connected to a connecting strip 28, and one end of the connecting strip 28 is fixedly installed with a groove inner ring 29.

[0038] The inner wall of the groove inner ring 29 is fixedly connected to multiple pressure shafts 30. The outer wall of each pressure shaft 30 is rotatably connected to a sleeve rod 31. A driving shaft 32 is rotatably connected to the inner wall of the sleeve rod 31, away from the pressure shaft 30. One end of the driving shaft 32 is fixedly mounted with a hinge block 33.

The sleeve frame plate 36 is fixedly connected to the pressure sleeve ring 10 and slidably connected to the pressure ring 6. The output end of the punching cylinder 25 is equipped with a multi-faceted synchronous combination punching assembly. Multiple pressure shafts 30 are arranged in a circular ring with equal spacing, and the concave pressure strips 34 are slidably connected to the pressure ring 6.

[0039] In this embodiment, as shown in the attached Figure 8 - Attachment Figure 11 As shown, the multi-faceted synchronous punching assembly includes a punching pressure sensor 37 fixedly mounted at the output end of the punching cylinder 25. A linkage bar 38 is fixedly connected to the bottom end of the linkage bar 38, to which a grooved outer ring 39 is welded. Multiple extrusion shafts 40 are fixedly connected to the inner wall of the grooved outer ring 39. Each extrusion shaft 40 is rotatably connected to a sleeve rod 41 on its outer wall. A push rod 42 is rotatably connected to the inner wall of the sleeve rod 41, away from the extrusion shaft 40. One end of the push rod 42 is fixedly connected to a concave block 43. Two punching tools 44 are fixedly connected to one side of the concave block 43. Both punching tools 44 are slidably connected to the lateral bending bar 35. A guide sleeve 45 is fixedly connected to one side of the bending plate 12. The punching tools 44 are slidably connected to the guide sleeve 45. The multiple extrusion shafts 40 are arranged in an equidistant circular pattern, with the center point of each extrusion shaft 40 higher than the center point of the push rod 42.

[0040] The method of using the office desk panel punching and shearing machine of the present invention is as follows:

[0041] First, when installing and using the present invention, first place the mounting plate 23 at the designated mounting position, punch holes in the mounting position according to the holes of the mounting plate 23, and then insert the expansion bolts into the holes of the mounting plate 23. The mounting plate 23 can then be fixed and installed. After being fixed, the mounting plate 23 can provide support for the socket frame 1. At the same time, the mounting plate 23 can provide stable support for the controller 24, ensuring that the support column 20 supports the support plate 21, the support plate 21 supports the positioning plate 22, the positioning plate 22 provides positioning support for the office desk 15, and the support column 20 provides support for the support frame 19. At the same time, the support frame 19 supports multiple pillars 18, the pillars 18 support the limit blocks 17, and the limit blocks 17 support and fix the punching shears 16. Then, the metal sheet 14 is inserted into the upper surface of the office desk 15, and the metal sheet 14 can be inserted into the gap surrounded by the multiple limit blocks 17.

[0042] Secondly, when the present invention performs a multi-sided synchronous punching, shearing, and bending combined process, the controller 24 activates the punching cylinder 2, which pushes the punching rod 3 downward. The punching rod 3 drives the punching pressure sensor 4 downward. The punching pressure sensor 4 causes the pressure plate 5 to move downward, which in turn drives the pressure ring 6 downward. Simultaneously, the pressure ring 6 drives multiple corner shears 13 to move downward synchronously. The multiple corner shears 13 punch downward at the edge corners of the metal sheet 14. Simultaneously, the fixed shears 16 and the corner shears 13 perform closed punching. When the pressure value sensed by the punching pressure sensor 4 is the same as the pressure value set by the controller 24, the controller 24 shuts off the punching cylinder 2. At the same time, the punching rod 3 drives the socket plate 7 to move downward, the socket plate 7 drives the linkage electric cylinder 8 to move downward, the linkage electric cylinder 8 drives the bending pressure sensor 9 to move downward synchronously, the bending pressure sensor 9 causes the pressure sleeve ring 10 to move downward, the pressure sleeve ring 10 drives multiple pressure columns 11 to move downward synchronously, so that multiple pressure columns 11 respectively drive multiple bending plates 12 to move downward synchronously.

[0043] After the multiple corner punching shears 13 have punched and sheared the metal sheet 14 at the corner positions, the controller 24 activates the linkage electric cylinder 8. The linkage electric cylinder 8 pushes the bending pressure sensor 9 downward, which drives the pressure ring 10 downward, which drives the multiple pressure columns 11 to move downward synchronously, and the multiple pressure columns 11 respectively drive the multiple bending plates 12 to move downward synchronously. The bending plates 12 press the upper surface of the metal sheet 14 downward, and the bending plates 12 drive the extended portion of the upper surface of the metal sheet 14 to bend downward 90 degrees, so that the extended portion of the upper surface of the metal sheet 14 is attached to the side of the office desk 15. In this way, the multiple extended portions of the upper surface of the metal sheet 14 are synchronously attached to multiple side positions of the outer wall of the office desk 15 according to the specified bending force. At the same time, the pressing ring 10 drives the sleeve frame plate 36 downward, which in turn drives the concave pressing strip 34 downward, which in turn drives the lateral bending strip 35 downward synchronously, and the lateral bending strip 35 drives the two punching tools 44 downward synchronously. When the pressure value sensed by the bending pressure sensor 9 matches the pressure value set by the controller 24, the controller 24 closes the linked electric cylinder 8.

[0044] Then, when the present invention performs multi-faceted lateral combined bending, the controller 24 activates the bending electric cylinder 26, which pushes the lateral pressure sensor 27 downward. The lateral pressure sensor 27 drives the connecting bar 28 downward, and the connecting bar 28 enables the inner ring 29 to move downward synchronously. The inner ring 29 drives the multiple pressing shafts 30 to move downward synchronously. Simultaneously, the pressing shafts 30 drive the top of the sleeve rod 31 downward, and the sleeve rod 31 drives the driving shaft 32 to move rightward. The driving shaft 32 drives the hinge block 33 to move rightward, and the hinge block 33 drives the concave pressing strip 34 to move rightward. The concave pressing strip 34 moves rightward along the inner wall of the sleeve frame plate 36. Simultaneously, the concave pressing strip 34 causes the lateral bending strip 35 to move rightward, and the lateral bending strip 35 moves rightward along the upper surface of the bending plate 12. In this way, the lateral bending bars 35 can drive the metal sheets 14 on the sides of the desk 15 to bend them in the side grooves of the desk 15, thereby simultaneously bending the metal sheets 14 on multiple sides of the desk 15. When the pressure value sensed by the lateral pressure sensor 27 matches the pressure value set by the controller 24, the controller 24 closes the bending cylinder 26.

[0045] Finally, the present invention performs multi-sided synchronous combined punching. The controller 24 activates the punching cylinder 25, which pushes the punching pressure sensor 37 downward. This in turn drives the linkage bar 38 downward, which in turn causes the outer ring 39 of the groove to move downward synchronously. The outer ring 39 in turn drives multiple extrusion shafts 40 to move downward synchronously. The extrusion shaft 40 drives the top of the sleeve rod 41 downward, while the bottom of the sleeve rod 41 drives the push rod 42 rightward. The push rod 42 drives the concave block 43 rightward, which causes two punching tools 44 to move rightward synchronously. Both punching tools 44 move rightward along the inner wall of the lateral bending bar 35. In this way, the two punching tools 44 can punch the metal sheet 14 on the side of the desk 15. The punching tools 44 within the multiple lateral bending bars 35 can also perform synchronous punching operations on the metal sheet 14 on multiple surfaces of the outer wall of the desk 15. When the pressure value sensed by the punching pressure sensor 37 is the same as the pressure value set by the controller 24 , the punching electric cylinder 25 is closed by the controller 24 .
