Description

Technical Field

[0001] This invention relates to the field of electrical control cabinet manufacturing technology, and in particular to a punching and blanking device for electrical control cabinet iron plates. Background Technology

[0002] During the production of electrical control cabinets, it is necessary to punch holes in the iron plates that make up the cabinets. Current production processes typically use CNC machine tools to punch holes in the iron plates. Moreover, modern CNC machine tools are large in scale, allowing large plates to be placed on them. A single automated operation can complete the processes of cutting multiple iron plates and punching holes in the plates. Furthermore, the same plate may contain multiple iron plates of various specifications used to assemble one electrical control cabinet, facilitating subsequent assembly of the cabinets.

[0003] However, some problems exist, especially during the blanking process, after punching holes in the metal plates for electrical control cabinets. Due to the increasingly high precision of the equipment used, the gaps at the outer edges of the cut and punched metal plates are very small, so the metal plates do not automatically fall off the sheet metal but remain adhered. Currently, manual blanking is used, requiring workers to perform the following operations: take the sheet metal from the CNC machine tool's output end, move the sheet metal to a worktable, shake the sheet metal by holding one end, fold the remaining frame after the sheet metal falls to reduce its footprint, remove the frame, and remove the sheet metal. This involves many manual steps, resulting in low work efficiency and high labor costs due to the need for shift work during long hours. Furthermore, conventional CNC machine tools can only transfer the workpiece to its output end; even if a portion of the workpiece extends beyond the output end, it cannot be completely detached. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides a punching and blanking device for electrical control cabinet iron plates, which can improve the blanking efficiency after punching electrical control cabinets and reduce labor costs.

[0005] In order to achieve the objectives of this invention, the following technologies are proposed: A punching and blanking device for an electrical control cabinet iron plate includes: The unloading platform includes a first half platform. A first rotary motor is provided on the side of one end of the first half platform, and a second half platform that matches the first half platform is provided at one end of its output shaft. A pair of conveyor units are located on both sides of the unloading platform to transfer the sheet metal to the unloading platform; The pressing and collecting unit is located at one end of the unloading platform. It includes a second rotary motor. A sixth linear mechanism is vertically arranged on the side of one end of the output shaft of the second rotary motor. The lower end of the output shaft of the sixth linear mechanism is provided with multiple inverted T-shaped parts. The long side of the inverted T-shaped parts has an opening that runs through the length direction. The upper end of the opening is connected to the air extraction pipe of an external air pump. The lower end of the inverted T-shaped parts is equipped with a pressing plate that matches the iron plate. The pressing plate has a flared mouth that runs through the length direction. Its upper end matches the opening of the inverted T-shaped parts. Multiple lifting units are located around the unloading platform to lift the frame when the pressing and closing unit presses the iron plate, and at least one lifting unit is provided on each side of the unloading platform.

[0006] Furthermore, there is a predetermined distance between the first half-stage and the second half-stage, and a vertically arranged first linear mechanism is provided below the first half-stage and the second half-stage, with a push plate at the upper end of its output shaft.

[0007] Furthermore, the conveying unit includes a second linear mechanism, a sliding carriage is provided on one side of the sliding end of the second linear mechanism, a pair of vertically arranged third linear mechanisms are provided on the sliding carriage, a fourth linear mechanism is provided at the upper end of its output shaft, a mounting plate is provided at one end of the output shaft of the fourth linear mechanism, a fixed plate is provided at the lower part of one side of the mounting plate, and a fifth linear mechanism is also provided on one side of the mounting plate, with a movable plate matching the fixed plate at the lower end of its output shaft.

[0008] Furthermore, a hanger is provided at the lower end of the output shaft of the sixth linear mechanism, and an inverted T-shaped part is provided at the lower end of the hanger. A port matching the opening is provided on the hanger, and a pipe for connecting an external air pump suction pipe is provided on the port.

[0009] Furthermore, the lifting unit includes a vertically arranged seventh linear mechanism, an eighth linear mechanism at one end of its output shaft, a crossbar at one end of the output shaft of the eighth linear mechanism, a plurality of first clamping plates on the crossbar, a third rotary motor at one end of the crossbar, a rotary roller at one end of its output shaft, and a plurality of second clamping plates matching the first clamping plates on the outer periphery of the rotary roller.

[0010] Furthermore, multiple grooves are formed inward on the three sides of the upper surface of the first half of the platform, and multiple grooves are also formed inward on the three sides of the upper surface of the second half of the platform, with the first clamping plate matching the grooves.

[0011] Furthermore, the punching and blanking device for the electrical control cabinet also includes a discharge auxiliary device located at one end of the CNC machine tool's discharge end. The discharge auxiliary device includes a mounting part, with a through rod on one side of the mounting part and several rollers sleeved on its outer periphery.

[0012] The beneficial effects of this technical solution are as follows: 1. The conveying unit can automatically transfer the sheet metal with iron plate from the CNC machine tool to the unloading table, eliminating the need for manual handling of the sheet metal.

[0013] 2. The iron plate is pressed down by the pressure plate of the pressing plate unit, and then the frame outside the iron plate is lifted by the lifting unit. The iron plate can be quickly separated from the sheet material without the need for manual shaking of the sheet material, saving time and manpower.

[0015] 4. The frame can be folded by rotating the second half onto the first half, eliminating the need for manual folding of the frame.

[0016] 5. The entire material cutting process only requires manual operation for removing the iron plate and the folded frame. It has a high degree of automation and can improve material cutting efficiency. Attached Figure Description

This device is used to punch and blank sheet metal for electrical control cabinets. Figure 14 The sheet metal 7 shown is cut from the discharge end of the punching equipment, and then the frame 71 is removed to obtain the iron plate 72 for the electrical control cabinet. Specifically, the punching equipment is usually completed in one piece by a CNC machine tool 6. The sheet metal 7 is cut with dividing lines to separate the iron plate 72, and various shapes of iron plate holes 73 are punched on the iron plate 72.

[0033] The unloading table 1 is installed at the discharge end of the CNC machine tool 6 for punching, and has a predetermined distance from it. The unloading table 1 includes a first half-table 11 mounted on multiple legs. Multiple grooves 12 are formed inward on three sides of the upper surface of the first half-table 11. A first rotary motor 13 is mounted on one side of the first half-table 11, and the first rotary motor 13 is mounted on a bracket. A second half-table 14, matching the first half-table 11, is located at one end of its output shaft. Multiple grooves 12 are also formed inward on three sides of the upper surface of the second half-table 14. Specifically, the side of the first half-table 11 without grooves 12 and the side of the second half-table 14 without grooves 12 are positioned opposite each other. There is a predetermined distance between the first half-platform 11 and the second half-platform 14. The other end of the second half-platform 14 is provided with a rotating rod, which is rotatably engaged with a rotating seat. The lower end of the second half-platform 14 is provided with a support 15 for lifting it when it is not rotating. Below the first half-platform 11 and the second half-platform 14, there is a vertically arranged first linear mechanism 16. The upper end of its output shaft is provided with a push plate 17 for pushing the middle of the frame part 71. The push plate 17 can move up and down in the space between the first half-platform 11 and the second half-platform 14. In use, the plate 7 is transported to the unloading table 1. Part of the plate 7 is located on the first half-platform 11 and part is located on the second half-platform 14.

[0034] There is a pair of conveying units 2, which are respectively located on both sides of the unloading table 1. They are used to accurately transfer the plate 7 from the output end of the CNC machine tool 6 to a predetermined position on the unloading table 1. The conveying unit 2 includes a second linear mechanism 21. One end of the second linear mechanism 21 extends to a position close to both sides of the CNC machine tool 6. A sliding carriage 22 is provided on one side of the sliding end of the second linear mechanism 21. A pair of vertically arranged third linear mechanisms 23 are provided on the sliding carriage 22. A fourth linear mechanism 24 is provided at the upper end of its output shaft. The output directions of the two fourth linear mechanisms 24 are arranged opposite to each other. A mounting plate 25 is provided at one end of the output shaft of the fourth linear mechanism 24. A fixed plate 26 is provided at the lower part of one side of the fourth linear mechanism 24. A fifth linear mechanism 27 is also provided on one side of the mounting plate 25. A movable plate 28 matching the fixed plate 26 is provided at the lower end of its output shaft. The fixed plate 26 and the movable plate 28 are used to clamp the plate 7.

[0035] The pressing and collecting unit 3 is located at one end of the unloading platform 1. It is used to press the iron plate 72 onto the unloading platform 1 during unloading and to remove the iron plate 72 after unloading is completed. The pressing and collecting unit 3 includes a second rotary motor 31 mounted on a base. One end of its output shaft is provided with a rotating rod, and one end of the rotating rod is provided with a vertically arranged sixth linear mechanism 32. The lower end of the output shaft of the sixth linear mechanism 32 is provided with a hanger 33. In this embodiment, the hanger 33 is an H-shaped frame. The lower end of the hanger 33 is provided with multiple inverted T-shaped parts 34. The long side of the inverted T-shaped part 34 has an opening that runs through it along the length direction. The short side of the inverted T-shaped part 34 has multiple through holes 35. In this embodiment, each of the two short sides has an opening. A through hole 35 is provided, and a through opening matching the opening is provided on the hanger 33. The through opening is provided with a pipe port 36 for connecting an external air pump. Specifically, the air pump is a vacuum pump. The lower end of the inverted T-shaped part 34 is equipped with a pressure plate 37 that matches the specific specifications of the iron plate 72. Specifically, the edge of the pressure plate 37 has a small gap with the edge of the iron plate 72, which can be 5mm to 20mm. A flared mouth 38 is provided through the pressure plate 37, and its upper end matches the opening of the inverted T-shaped part 34. The diameter of the lower end of the flared mouth 38 is larger than the diameter of the upper end. Several screw holes 39 matching the through hole 35 are provided on the upper surface of the pressure plate 37.

[0036] Multiple lifting units 4 are arranged around the unloading platform 1 to lift the frame 71 when the pressing and collecting unit 3 presses the iron plate 72. At least one lifting unit 4 is provided on each side of the unloading platform 1. In this embodiment, one lifting unit 4 is provided at each end of the unloading platform 1, and two lifting units 4 are provided on each side of the unloading platform 1. Each lifting unit 4 includes a vertically arranged seventh linear mechanism 41, with an eighth linear mechanism 42 at one end of its output shaft. A base plate 43 is provided at one end of the output shaft of the eighth linear mechanism 42, and a crossbar 44 is provided on the base plate 43. A mounting base 45 is provided on one side of the crossbar 44. Several first clamping plates 46 that match the groove 12 are provided on the crossbar 44. A third rotary motor 47 is provided on the mounting base 45. A rotary roller 48 is provided at one end of its output shaft. Several second clamping plates 49 that match the first clamping plates 46 are provided on the outer periphery of the rotary roller 48. The second clamping plates 49 can be rotated to be located above the first clamping plates 46. The second clamping plates 49 are relatively thin and can form a gap with the first clamping plates 46 that matches the thickness of the plate 7, so that the first clamping plates 46 and the second clamping plates 49 can clamp the frame part 71.

[0037] As another implementation, there can be one lifting unit 4 on each side of the unloading platform 1. In this case, the lifting unit 4 needs to be set at a position further away from the unloading platform 1, and then the first clamping plate 46 and the second clamping plate 49 are lengthened so as to avoid the first rotary motor 13 and the rotating seat.

[0038] The discharge aid 5 is located at one end of the discharge end of the CNC machine tool 6, and is used to make the plate 7 be moved out of the end of the CNC machine tool 6 more smoothly. The discharge aid 5 includes a mounting part 51. In this embodiment, the discharge end of the CNC machine tool 6 includes an end plate 61 and a brush worktable 62 located on its upper end surface. Specifically, the mounting part 51 includes a vertical plate and a horizontal part. The vertical plate is fixed to one end of the end plate 61. The specific fixing method can be screw connection. A through rod 52 is provided on one side of the mounting part 51, and several rollers 53 are sleeved on its outer periphery.

[0039] In this embodiment, the first linear mechanism 16, the third linear mechanism 23, the fourth linear mechanism 24, the fifth linear mechanism 27, the sixth linear mechanism 32, the seventh linear mechanism 41, and the eighth linear mechanism 42 all adopt single-axis linear cylinders, while the second linear mechanism 21 adopts a rodless linear cylinder.

[0040] Work style: The device is assembled according to the shape and size of the iron plate 72 on the plate 7: the inverted T-shaped part 34 and the pressure plate 37 corresponding to the iron plate 72 are connected by screws, and the air pump's suction pipe is connected to the pipe opening 36. Specifically, since multiple specifications of iron plates 37 may be processed on one plate 7 at a time, the installation positions of the pressure plates 37 of each specification in the pressing and collecting unit 3 are arranged according to the positions cut out by the CNC machine tool 6 for each iron plate 72.

[0041] The sheet metal 7 is transported via the conveying unit 2: the sliding carriage 22 is moved by the second linear mechanism 21, the height of the mounting plate 25 is adjusted by each of the third linear mechanisms 23, the movable plate 28 is controlled by the fifth linear mechanism 27 to rise, the mounting plate 25 is brought closer to the sheet metal 7 by the fourth linear mechanism 24, and then the movable plate 28 is lowered by the fifth linear mechanism 27 to clamp the sheet metal 7 together with the fixed plate 26. This process is repeated until the sheet metal 7 is transferred after clamping and placed at a predetermined position on the unloading table 1. Specifically, during this process, the rollers 53 of the unloading aid 5 enable the sheet metal 7 to be moved more smoothly out of the end of the CNC machine tool 6.

[0042] The second rotary motor 31 rotates the components at one end of its output shaft to a position such that... Figure 6 In the state shown, the sixth linear mechanism 32 presses each pressure plate 37 down onto each iron plate 72. Then, the seventh linear mechanism 41 and the eighth linear mechanism 42 move the first clamping plate 46 so that the first clamping plate 46 extends between the groove 12 and the plate 7, specifically, between the groove 12 and the frame 71. The third rotary motor 47 rotates the second clamping plate 49 to clamp the frame 71. The seventh linear mechanism 41 lifts the frame 71, while the first linear mechanism 16 controls the push plate 17 to lift the middle frame 71, so that the frame 71 and the iron plate 72 are separated.

[0043] The external air pump is started, and the air path passes through the suction pipe, the pipe port 36, the opening of the hanger 33, the opening of the inverted T-shaped part 34, and the flared mouth 38 in sequence to pick up the iron plate 72. The sixth linear mechanism 32 lifts the iron plate 72 until the iron plate 72 is higher than the frame part 71. The second rotary motor 31 rotates the rotating rod 180°, and the iron plate 72 is rotated to the side. At this time, the iron plate 72 is located on the pressure plate 37. The air pump stops sucking air, and the staff can then remove the iron plate 72.

[0044] The frame 71 is lowered by the lifting unit 4, and then the second half of the platform 14 is controlled by the first rotary motor 13 to bend a portion of the frame 71, making the frame 71 almost folded in half, reducing the occupied area. The staff then removes the frame 71, which has become scrap. Specifically, to prevent the frame 71 from sliding when bending it, the frame 71 on the first half of the platform 11 can be fixed by part of the lifting unit 4.

[0045] The above are only some of the embodiments listed in this application and are not intended to limit this application.
