[0002] In the production and manufacturing process of a server cabinet, the cabinet frame, as the core component for supporting and installing server devices, directly affects the overall stability and reliability of the cabinet. The cabinet frame mainly consists of vertical columns and horizontal beams to form the main frame. When processing the columns, punching is required. Currently, the stamping process, with its characteristics of high efficiency and precision, has become the mainstream processing method for punching the columns of the server cabinet frame. This process uses the cooperation of a punch and a die to punch various holes on the column plate that meet the installation requirements.

[0003] Multiple types of holes need to be punched on the columns of the server cabinet frame, and their processing accuracy directly affects the cabinet stability and equipment adaptability. Currently, the industry generally uses multiple dedicated punching devices to punch holes of different shapes separately. Each time the device is changed for processing, the column needs to be repositioned and clamped. Due to the deviation of the positioning reference, clamping error, and human operation differences, the errors accumulate continuously during multiple positionings, resulting in problems such as hole position deviation and inaccurate hole spacing, which will affect the processing accuracy, and repositioning and clamping will reduce the punching efficiency.

[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 column is fixed, the electric slide drives the column to move horizontally through the mounting frame and stops running when the punching point of the column is aligned with the punch.

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: 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.

[0018] 2. While the present invention clamps and fixes both ends of the column through the limiting plate, it enables the sliding layer to unfold and fit against the inner wall of the column to achieve the effect of internal support. Moreover, by the inclined surface of the limiting plate abutting against the upper edge of both ends of the column, the effect of top limiting the column can be achieved, realizing the effect of multi-directional support and fixation of the column, and preventing the column from shaking or falling off.

[0019] 3. When the sliding layer of the present invention slides and fits against the central layer after punching, the waste residue 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 the upward movement of the upper baffle, thereby realizing the automatic discharge of the waste in the side female die and the upper female die.

[0020] 4. The present invention inclines the bottom die by rotating the rotating plate downward, so that the column on the mounting plate and the falling waste slide down, realizing the automatic blanking of the waste and the column, and keeping the surface of the mounting plate clean.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to the attached Figure 1 - attached Figure 3 As shown in the figure, an embodiment of the present invention provides a punching processing device for the frame of a server cabinet, including a base 1. An electric slide table 2 is fixedly connected to the upper surface of the base 1. An upper mounting plate 3 is fixedly connected above the slider of the electric slide table 2. A bottom die 4 is fixedly connected to the upper surface of the mounting plate 3. A column 5 in an inverted U shape for the frame to be processed is arranged above the bottom die 4. Clamps 6 are arranged at both ends of the column 5. The clamps 6 are used for positioning and clamping the column 5. A U-shaped mounting bracket 7 is fixedly connected to the center of the upper surface of the base 1. Punching cylinders 12 are fixedly connected to the top and side walls of the mounting bracket 7 respectively. A punch 9 is fixedly connected to the driving end of the punching cylinder 12. An upper female die 10 and a side female die 11 are respectively formed on the upper surface and both side walls of the bottom die 4. The shapes of the upper female die 10 and the side female die 11 are set according to the shapes of the holes to be punched in the column 5, and can be set as semi-waist-shaped, circular or square, and one or more combinations thereof. In this embodiment, the upper female die 10 is semi-waist-shaped, that is, composed of a semicircular part and a rectangular part, and the side female die 11 is circular. At the same time, the punch 9 at the top is set as a semi-waist shape matching the shape of the upper female die 10, and the punches 9 on both sides are set as circular shapes matching the shape of the side female die 11.

[0025] Specifically, during use, the upright post 5 is placed on the bottom die 4 for support, and both ends of the upright post 5 are clamped and fixed by the fixture 6. After the upright post 5 is fixed, the electric sliding table 2 runs to drive the upright post 5 to move horizontally through the mounting bracket 7 and stops running when the punching point on the upright post 5 aligns with the punch 9. Then, the punching cylinder 12 extends to drive the punch 9 to move towards the upright post 5, and through the cooperation of the punch 9 with the upper female die 10 and the side female die 11, punching is performed on the upper surface and both sides of the upright post 5. After punching is completed, the electric sliding table 2 runs again to align the next punching point on the upright post 5 with the punch 9, so as to perform punching processing on the surface of the upright post 5 in sequence. This device performs single positioning on the upright post 5 through the fixture 6 and performs multiple processing through the punch 9, thereby reducing the accumulation of errors and improving the punching accuracy.

[0026] Please refer to the attached Figure 3 , the bottom die 4 is U-shaped, and the fixture 6 includes two electric push cylinders 61. The two electric push cylinders 61 are respectively fixedly arranged on both sides of the bottom die 4, and the driving ends of the electric push cylinders 61 are fixedly connected with push blocks 62.

[0027] Specifically, after the upright post 5 is placed on the bottom die 4, by running the two electric push cylinders 61 to drive the two push blocks 62 to move towards both ends of the upright post 5 respectively, so as to push the upright post 5 to move until the midpoint of the upright post 5 coincides with the midpoint of the bottom die 4, and then the push blocks 62 abut against both ends of the upright post 5 for fixation, thereby achieving the effects of positioning and fixing the upright post 5 and improving the stability of the upright post 5 during processing.

[0028] Please refer to the attached Figure 4 - attached Figure 5 , the bottom die 4 includes a central layer 41, sliding layers 42 are respectively arranged on both sides of the central layer 41. The sliding layer 42 includes vertical plates, and two groups of horizontal plates slidably connected to the sliding grooves 43 are respectively arranged on both sides of the vertical plates. Two ends are respectively arranged on both sides of the sliding layer 42. Four groups of sliding grooves 43 are respectively opened at both ends of the central layer 41. The ends of the sliding layer 42 are slidably connected to the sliding grooves 43. The inner side wall of the sliding groove 43 is fixedly connected with a first elastic member 44. The first elastic member 44 adopts elastic elements such as anti-fatigue springs or elastic plastics. One end of the first elastic member 44 away from the inner side wall of the sliding 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. Positioning columns 45 with annular protrusions on the surface are respectively fixedly connected to both sides of the central layer 41. The outer wall of the positioning column 45 penetrates through the sliding layer 42, and the sliding position of the sliding layer 42 is limited by the annular protrusions, so that when the sliding layer 42 abuts against the annular protrusions, the distance between the two sliding layers 42 and the total thickness are the same as the width inside the upright post 5.

[0029] Specifically, the first elastic member 44 applies an elastic force to the sliding layer 42, so that the sliding layer 42 fits the central layer 41, thereby reducing the width of the bottom die 4 and facilitating the insertion of the upright post 5.

[0030] Please refer to the attached Figure 5 - Attachment Figure 6 The pushing block 62 includes an L-shaped connecting block 621. A generally trapezoidal limiting plate 622 is slidably connected to the inner bottom wall of the connecting block 621. Two trapezoidal pressing blocks 623 are arranged on one side of the limiting plate 622. A slope is provided on the side of the limiting plate 622 facing the column 5, and a rounded corner is provided on the side of the limiting plate 622 facing the pressing block 623. A triangular pressing member 624 is formed by the downward protrusion of the bottom end of the pressing block 623, and the sharp end of the bottom of the pressing member 624 is aligned with the intersection of the central layer 41 and the sliding layer 42.

[0031] Specifically, after the column 5 is inserted, the pushing block 62 moves towards the column 5 under the push of the electric push cylinder 61, and the limiting plate 622 abuts against the column 5. When the limiting plate 622 abuts against the column 5, under the action of the reaction force, the limiting plate 622 slides into the interior of the connecting block 621, so that the limiting plate 622 moves along the upper slope of the pressing block 623 and pushes the pressing block 623 to move downward. When the pressing block 623 moves downward, it drives the pressing member 624 to insert into the gap between the central layer 41 and the sliding layer 42. As the pressing member 624 is gradually inserted, it pushes the sliding layer 42 to slide gradually outward until it abuts against the annular protrusion on the surface of the positioning column 45. Thus, while clamping and fixing the two ends of the column 5 through the limiting plate 622, the sliding layer 42 is unfolded and attached to the inner wall of the column 5 to achieve the effect of inner support. And by the slope of the limiting plate 622 abutting against the upper edges of the two ends of the column 5, the effect of top limiting the column 5 can be achieved, realizing the effect of multi-directional support and fixation of the column 5 and preventing the column 5 from shaking or falling off.

[0032] Please refer to the attached Figure 6 The side wall of the pressing block 623 is slidably connected to the inner side wall of the connecting block 621. The top of the pressing block 623 is fixedly connected with an elastic telescopic rod 626. The elastic telescopic rod 626 includes an upper cylinder body. A T-shaped lower rod body is slidably connected inside the upper cylinder body. An elastic element is sleeved on the surface of the lower rod body. The top end of the elastic telescopic rod 626 is fixedly installed on the inner top wall of the connecting block 621. An elastic member two 625 is fixedly connected to the side wall of the limiting plate 622. The elastic member two 625 is made of elastic elements such as anti-fatigue springs or elastic plastics. The end of the elastic member two 625 away from the limiting plate 622 is fixedly installed on the inner side wall of the connecting block 621.

[0033] Specifically, the elastic telescopic rod 626 is used to apply an upward pulling force to the pressing block 623, so that the position of the pressing member 624 is relatively high initially and after the subsequent clamping ends and it no longer inserts between the central layer 41 and the sliding layer 42. The elastic member two 625 is used to apply an elastic force to the limiting plate 622, so that the limiting plate 622 is staggered from the pressing block 623 when it slides outward along the connecting block 621 initially.

[0034] Please refer to the attached Figure 7 - attached Figure 9 , the side die cavity 11 adopts a through-hole 111 structure. An annular groove 112 is provided inside the through-hole 111. A side baffle 113 in the shape of a stepped cylinder is slidably connected inside the annular groove 112. A limiting post 114 is provided on one side of the side baffle 113 facing the central layer 41. One end of the limiting post 114 away from the side baffle 113 is fixedly connected to the side wall of the central layer 41. The side baffle 113 is composed of a superposition of a large circular block and a small circular block. The diameter of the large circular block is the same as the diameter of the annular groove 112, and the diameter of the small circular block is the same as the diameter of the through-hole 111.

[0035] Specifically, when the punch 9 punches the side die cavity 11, at this time, the sliding layer 42 and the central 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 circular block slides against the other side of the annular groove 112 to limit the side baffle 113, so that the punch 9 abuts against the side baffle 113 for punching. After punching, when the sliding layer 42 slides and fits the central layer 41, due to the limitation of the limiting post 114, the side baffle 113 can push the waste remaining inside the through-hole 111 out of the through-hole 111 when the sliding layer 42 slides towards the central layer 41, thus realizing the automatic discharge of the waste inside the side die cavity 11.

[0036] Please refer to the attached Figure 7 - attached Figure 9 , the upper die cavity 10 adopts a groove 101 structure. A T-shaped upper baffle 102 is provided at the bottom of the groove 101. The bottom end of the upper baffle 102 penetrates the central layer 41. 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 penetrates the central layer 41 and is fixedly connected to the side wall of the sliding layer 42. An inclined plane is provided at one end of the lifting block 103 located inside the upper die cavity 10. The upper baffle 102 includes a top plate and a rod body at the bottom. The shape of the top plate is the same as that of the groove 101.

[0037] Specifically, when the punch 9 punches the upper groove 101, at this time, the sliding layer 42 drives the lifting block 103 to move outward, so that the bottom end of the upper baffle 102 abuts against the lower side of the inclined plane of the lifting block 103, thereby reducing the height of the upper baffle 102 and making the lower surface of the top plate fit the inner bottom wall of the groove 101. After punching, when the sliding layer 42 slides and fits the central layer 41, the lifting block 103 moves into the central layer 41, and the bottom end of the upper baffle 102 slides upward along the inclined plane of the lifting block 103, so that when the upper baffle 102 moves upward, it pushes the waste in the groove 101 out of the groove 101, realizing the automatic discharge of the waste inside the upper die cavity 10.

[0038] Please refer to 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.

[0039] 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.

[0040] 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 .

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.
