[0002] In the production and manufacturing process of server cabinets, the cabinet frame is the core component for supporting and installing server equipment. Its processing quality directly affects the overall stability and reliability of the cabinet. The cabinet frame is mainly composed of vertical columns and horizontal beams to form the main frame. The columns need to be punched during processing. At present, the stamping process has become the mainstream processing method for punching the columns of server cabinet frames due to its high efficiency and precision. This process uses the cooperation of the punch and the die to punch out various holes on the column plate that meet the installation requirements.

[0003] The columns of server cabinet frames require punching holes of various shapes, and the precision of these punching operations directly impacts cabinet stability and equipment compatibility. Currently, the industry generally uses multiple specialized punching machines to punch holes of different shapes. Each change in equipment requires repositioning and re-clamping the columns. Due to positioning reference deviations, clamping errors, and human variability, repeated positioning leads to cumulative errors, resulting in offset holes and inaccurate hole spacing, which in turn affect processing accuracy.

[0016] Working principle: When in use, place the column on the bottom mold for support, and drive the two push blocks to move to the two ends of the column respectively by running the two electric push cylinders, thereby pushing the column to move until the midpoint of the column is consistent with the midpoint of the bottom mold. The push blocks are pressed against the two ends of the column to fix it, thereby achieving the effect of positioning and fixing the column, and improving the stability of the column during processing. When clamping, the push blocks are pushed toward the column by the electric push cylinder. While clamping the two ends of the column through the limit plate, the sliding layer is expanded and fits the inner wall of the column to achieve the effect of internal support, and the inclined surface of the limit plate is pressed against the upper edge of the two ends of the column to achieve the effect of top limiting the column, realizing the multi-directional support and fixation of the column, and preventing the column from shaking or falling off.

After the punching is completed, the electric slide drives the mounting plate to move against the extrusion plate, so that the column and the fallen waste on the mounting plate slide down, so that the waste and the column are automatically unloaded, keeping the surface of the mounting plate clean.

[0017] The present invention provides a punching device for a server cabinet frame. It has the following beneficial effects:

[0018] 1. The present invention uses a fixture to perform a single positioning of the column, and then uses an electric slide to transport the column to move through the punch for punching. The punch performs multiple processing without repeatedly disassembling and assembling the column, thereby reducing the accumulation of errors and improving the punching accuracy.

[0019] 2. The present invention clamps and fixes the two ends of the column through the limiting plate, while allowing the sliding layer to expand and fit the inner wall of the column to achieve the effect of internal support, and the inclined surface of the limiting plate is pressed against the upper edge of the two ends of the column, which can achieve the effect of top limiting the column, realizing the multi-directional support and fixation of the column, and preventing the column from shaking or falling off.

[0020] 3. When the sliding layer slides and fits the center layer after punching, the waste remaining inside the through hole can be pushed out of the through hole by the limiting column, and the waste in the groove is pushed out of the groove by moving the upper baffle upward, thereby realizing the automatic discharge of the waste in the side die and the upper die.

[0021] 4.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Please see the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a punching processing device for a server cabinet frame, comprising a base 1, an electric slide 2 is fixedly connected to the upper surface of the base 1, a mounting plate 3 is fixedly connected above the slider of the electric slide 2, a bottom mold 4 is fixedly connected to the upper surface of the mounting plate 3, a U-shaped column 5 of the frame to be processed is arranged above the bottom mold 4, a clamp 6 is arranged at both ends of the column 5, the clamp 6 is used to position and clamp the column 5, a U-shaped mounting frame 7 is fixedly connected at the center of the upper surface of the base 1, and a punching cylinder 12 is fixedly connected to the top and side walls of the mounting frame 7 respectively. The punching cylinder 12 The driving end is fixedly connected to a punch 9, and an upper die 10 and a side die 11 are respectively provided on the upper surface and the two side walls of the bottom die 4. The shapes of the upper die 10 and the side die 11 are set according to the shape of the hole to be punched in the column 5, and can be set to a semi-waist type, a circle or a square, or a combination of one or more thereof. In this embodiment, the upper die 10 adopts a semi-waist type, which is composed of a semicircular part and a rectangular part, and the side die 11 adopts a circle. At the same time, the punch 9 on the top is set to a semi-waist type that matches the shape of the upper die 10, and the punches 9 on both sides are set to a circle that matches the shape of the side die 11.

[0038] Specifically, when in use, the column 5 is placed on the bottom die 4 for support, and the two ends of the column 5 are clamped and fixed by the clamp 6. After the column 5 is fixed, the electric slide 2 is used to drive the column 5 to move horizontally through the mounting frame 7 and stop running when the punching point of the column 5 is aligned with the punch 9. The punching cylinder 12 is operated to extend and drive the punch 9 to move toward the direction of the column 5. The punch 9 cooperates with the upper die 10 and the side die 11 to punch the upper surface and both sides of the column 5. After the punching is completed, the electric slide 2 is operated again to align the next punching point of the column 5 with the punch 9, thereby punching the surface of the column 5 in turn. The device performs a single positioning of the column 5 by the clamp 6 and performs multiple processing by the punch 9, thereby reducing the accumulation of errors and improving the punching accuracy.

[0039] Please see the attached Figure 3 The bottom mold 4 is set to be U-shaped, and the clamp 6 includes two electric push cylinders 61. The two electric push cylinders 61 are respectively fixedly arranged on both sides of the bottom mold 4, and the driving end of the electric push cylinder 61 is fixedly connected to the push block 62.

[0040] Specifically, after the column 5 is placed on the bottom mold 4, the two electric push cylinders 61 are operated to drive the two push blocks 62 to move toward the two ends of the column 5 respectively, thereby pushing the column 5 to move until the midpoint of the column 5 is consistent with the midpoint of the bottom mold 4. The push blocks 62 are pressed against the two ends of the column 5 to fix it, thereby achieving the effect of positioning and fixing the column 5, and improving the stability of the column 5 during processing.

[0041] Please see the attached Figure 4 -Attached Figure 5 The bottom mold 4 includes a center layer 41, and sliding layers 42 are respectively provided on both sides of the center layer 41. The sliding layer 42 includes vertical plates, and two groups of horizontal plates slidably connected to the slide groove 43 are respectively provided on both sides of the vertical plates. Two ends are respectively provided on both sides of the sliding layer 42, and four groups of slide grooves 43 are respectively opened at both ends of the center layer 41. The end of the sliding layer 42 is slidably connected to the slide groove 43, and the inner wall of the slide groove 43 is fixedly connected with an elastic member 44. The elastic member 44 adopts an elastic element such as a fatigue-resistant spring or elastic plastic. The end of the elastic member 44 away from the inner wall of the slide groove 43 is fixedly connected to the inner wall of the sliding layer 42. A notch is opened at the top of the sliding layer 42, and a positioning column 45 with an annular protrusion on the surface is fixedly connected on both sides of the center layer 41. The outer wall of the positioning column 45 passes through the sliding layer 42, and the sliding position of the sliding layer 42 is limited by the annular protrusion, so that when the sliding layer 42 is against the annular protrusion, the distance and thickness of the two sliding layers 42 are the same as the width of the inner side of the column 5.

[0042] Specifically, the elastic member 44 exerts elastic force on the sliding layer 42 so that the sliding layer 42 fits the central layer 41 , thereby reducing the width of the bottom mold 4 and facilitating the insertion of the column 5 .

[0043] Please see the attached Figure 5 -Attached Figure 6 The push block 62 includes an L-shaped connecting block 621, and the inner bottom wall of the connecting block 621 is slidably connected to a trapezoidal limiting plate 622 as a whole. Two trapezoidal extrusion blocks 623 are provided on one side of the limiting plate 622. The side of the limiting plate 622 facing the column 5 is provided with an inclined surface, and the side of the limiting plate 622 facing the extrusion block 623 is provided with a rounded corner. The bottom end of the extrusion block 623 protrudes downward to form a triangular extrusion piece 624, and the sharp end of the bottom of the extrusion piece 624 is aligned with the intersection of the center layer 41 and the sliding layer 42.

[0044] Specifically, after the column 5 is inserted, the push block 62 moves toward the column 5 under the push of the electric push cylinder 61, and makes the limit plate 622 press against the column 5. When the limit plate 622 presses against the column 5, under the action of the reaction force, the limit plate 622 slides toward the inside of the connecting block 621, so that the limit plate 622 moves along the upper inclined surface of the extrusion block 623 and pushes the extrusion block 623 to move downward. When the extrusion block 623 moves downward, it drives the extrusion piece 624 to be inserted into the gap between the central layer 41 and the sliding layer 42. The gradual insertion of the extrusion piece 624 pushes the sliding layer 42 to slide gradually outward until it contacts the annular protrusion on the surface of the positioning column 45, thereby clamping and fixing the two ends of the column 5 through the limiting plate 622, and allowing the sliding layer 42 to expand and fit the inner wall of the column 5 to achieve the effect of internal support, and the inclined surface of the limiting plate 622 contacts the upper edges of the two ends of the column 5, which can achieve the effect of top limiting the column 5, realizing the effect of multi-directional support and fixation of the column 5, and preventing the column 5 from shaking or falling off.

[0045] Please see the attached Figure 6 The side wall of the extrusion block 623 is slidably connected to the inner wall of the connecting block 621, and the top of the extrusion block 623 is fixedly connected to an elastic telescopic rod 626. The elastic telescopic rod 626 includes an upper cylinder, and the interior of the upper cylinder is slidably connected to a T-shaped lower rod. The surface of the lower rod is sleeved with an elastic element. The top of the elastic telescopic rod 626 is fixedly mounted on the inner top wall of the connecting block 621, and the side wall of the limiting plate 622 is fixedly connected to an elastic part 2 625. The elastic part 2 625 adopts an elastic element such as a fatigue-resistant spring or elastic plastic. The end of the elastic part 2 625 away from the limiting plate 622 is fixedly mounted on the inner wall of the connecting block 621.

[0046] Specifically, the elastic telescopic rod 626 is used to apply an upward pulling force to the extrusion block 623, so that the extrusion member 624 is initially positioned higher and is no longer inserted between the central layer 41 and the sliding layer 42 after the subsequent clamping is completed. The elastic member 625 is used to apply an elastic force to the limit plate 622, so that the limit plate 622 slides outward along the connecting block 621 and is initially offset from the extrusion block 623.

[0047] Please see the attached Figure 7 -Attached Figure 9 The side die 11 adopts a through hole 111 structure, an annular groove 112 is opened inside the through hole 111, and a side baffle 113 in the shape of a stepped cylinder is slidably connected inside the annular groove 112. A limiting column 114 is provided on the side of the side baffle 113 facing the center layer 41, and the end of the limiting column 114 away from the side baffle 113 is fixedly connected to the side wall of the center layer 41. The side baffle 113 is composed of a large round block and a small round block stacked together, wherein the diameter of the large round block is the same as the diameter of the annular groove 112, and the diameter of the small round block is the same as the diameter of the through hole 111.

[0048] Specifically, when the punch 9 punches the side die 11, the sliding layer 42 and the center layer 41 maintain a fixed distance. When the punch 9 is inserted into the through hole 111, it pushes the side baffle 113 to move until the large round block slides against the other side of the annular groove 112 to limit the side baffle 113, so that the punch 9 presses against the side baffle 113 to punch. After the punching is completed, when the sliding layer 42 slides to fit the center layer 41, the side baffle 113 is restricted by the limiting column 114 so that the waste remaining in the through hole 111 can be pushed out of the through hole 111 when the sliding layer 42 slides toward the center layer 41, thereby realizing the automatic discharge of the waste in the side die 11.

[0049] Please see the attached Figure 7 -Attached Figure 9 The upper die 10 adopts a groove 101 structure, and a T-shaped upper baffle 102 is provided at the bottom of the groove 101. The bottom end of the upper baffle 102 passes through the center layer 41, and a lifting block 103 is provided on the lower side of the bottom end of the upper baffle 102. One end of the lifting block 103 passes through the center layer 41 and is fixedly connected to the side wall of the sliding layer 42. The lifting block 103 is located at one end inside the upper die 10 and is provided with a beveled surface. The upper baffle 102 includes a top plate and a rod body at the bottom, and the shape of the top plate is consistent with the groove 101.

[0050] Specifically, when the punch 9 punches the upper groove 101, the sliding layer 42 drives the lifting block 103 to move outward, so that the bottom end of the upper baffle 102 rests against the lower side of the inclined surface of the lifting block 103, thereby lowering the height of the upper baffle 102, so that the lower surface of the top plate fits the inner bottom wall of the groove 101. After the punching is completed, when the sliding layer 42 slides to fit the center layer 41, the lifting block 103 moves into the center layer 41, and makes the bottom end of the upper baffle 102 slide upward along the inclined surface of the lifting block 103, thereby pushing the waste in the groove 101 out of the groove 101 when the upper baffle 102 moves upward, thereby realizing the automatic discharge of the waste in the upper die 10.

[0051] Please see the attached Figure 10 -Attached Figure 13The cam 33 is a handle that is fixed on the top of the cam 33 and the handle 33 is fixed on the top of the cam 33. The cam 33 is a handle that is fixed on the top of the cam 33 and the handle 33 is fixed on the top of the cam 33. The cam 33 is a handle that is fixed on the top of the cam 33 and the handle 33 is fixed on the top of the cam 33.

[0052] When the cam 312 is in the unlocked position, the upper and lower plates 311 are pushed against the support rails 314 to release the support rails 312, and the lower plate 312 is pushed against the support rails 314 to release the support rails 312.

[0053] Please see the attached Figure 10 The upper surface of the base 1 is fixedly connected to a limiting layer 13 , and one end of the limiting layer 13 close to the center of the base 1 is provided with a bend, and the side wall of the limiting layer 13 is in contact with the side end of the mounting plate 3 .

[0054] Specifically, the upper plate 31 is limited by the limiting layer 13 so that the upper plate 31 always presses against the limiting layer 13 during the moving punching process, thereby maintaining stability and avoiding sliding. When the punching is completed, the upper plate 31 moves and is offset from the limiting layer 13.

[0055] Working process: When in use, the column 5 is placed on the bottom mold 4 for support, and the two electric push cylinders 61 are operated to drive the two push blocks 62 to move to the two ends of the column 5 respectively, thereby pushing the column 5 to move until the midpoint of the column 5 is consistent with the midpoint of the bottom mold 4. The push blocks 62 are pressed against the two ends of the column 5 for fixation, thereby achieving the effect of positioning and fixing the column 5, and improving the stability of the column 5 during processing.

[0056] During clamping, the push block 62 moves toward the column 5 under the push of the electric push cylinder 61, and makes the limit plate 622 press against the column 5. When the limit plate 622 presses against the column 5, under the action of the reaction force, the limit plate 622 slides toward the inside of the connecting block 621, so that the limit plate 622 moves along the upper inclined surface of the extrusion block 623 and pushes the extrusion block 623 to move downward. When the extrusion block 623 moves downward, it drives the extrusion piece 624 to insert into the gap between the central layer 41 and the sliding layer 42. As the extrusion piece 624 is gradually inserted, the sliding layer 42 is pushed to slide gradually outward until it contacts the annular protrusion, thereby clamping and fixing the two ends of the column 5 through the limiting plate 622, and allowing the sliding layer 42 to expand and fit the inner wall of the column 5 to achieve the effect of internal support. Moreover, the inclined surface of the limiting plate 622 contacts the upper edges of the two ends of the column 5, which can achieve the effect of top limiting the column 5, realizing the effect of multi-directional support and fixation of the column 5, and preventing the column 5 from shaking or falling off.

[0057] After the column 5 is fixed, the electric slide 2 is used to drive the column 5 to move horizontally through the mounting frame 7 and stops running when the punching point of the column 5 is aligned with the punch 9. The punching cylinder 12 is extended to drive the punch 9 to move toward the direction of the column 5. The punch 9 cooperates with the upper die 10 and the side die 11 to punch the upper surface and both sides of the column 5. After the punching is completed, the electric slide 2 is run again to align the next punching point of the column 5 with the punch 9, thereby performing punching processing on the surface of the column 5 in turn. The device performs a single positioning of the column 5 through the clamp 6 and performs multiple processing through the punch 9, thereby reducing the accumulation of errors and improving the punching accuracy.

[0058] After the punching is completed, the electric slide 2 drives the mounting plate 3 to move against the extrusion plate 14, and the sliding plate 311 is limited by the extrusion plate 14, so that the sliding plate 311 moves vertically along the inclined surface of the extrusion plate 14 when it moves horizontally, and at the same time pushes the rotating plate 312 to move. When the rotating plate 312 moves and is staggered with the lower plate 32, the rotating plate 312 rotates downward to tilt the bottom mold 4, thereby causing the columns 5 on the mounting plate 3 and the fallen waste to slide off, so that the waste and the columns 5 are automatically unloaded, keeping the surface of the mounting plate 3 clean.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
