Description

Technical Field

[0001] This utility model relates to the field of steel processing technology, specifically to a punching device for steel processing. Background Technology

[0002] Steel is a material with a certain shape, size and properties made from steel ingots, billets or steel through pressure processing. Steel has a wide range of applications and is an essential material for national construction and modernization. According to different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products. Due to different usage environments, punching equipment is needed to punch holes of various shapes in the steel to meet different usage requirements.

[0003] Patent No. 202322722863.7 discloses a punching device for steel processing. When the device is in contact, the spring on the limiting plate plays an effective buffering role on the punching rod, avoiding damage to the limiting plate caused by the continuous punching on the punching rod.

[0004] However, existing steel processing punching devices directly place the steel to be processed into the limiting groove for punching. However, the steel is used in different environments and the punching positions are also different. The operator needs to constantly adjust the position of the steel to complete the punching of different positions. The operation is cumbersome and the workload is large, which has a certain impact on the processing efficiency of steel. Therefore, a steel processing punching device is designed. Utility Model Content

[0005] The main purpose of this utility model is to provide a punching device for steel processing. This utility model solves the problem that existing punching devices for steel processing are inconvenient to adjust the position of steel and have low punching efficiency during use by setting up a drive component, a limit frame, a limit plate A, a limit plate B, and a drive block.

[0006] The technical solution adopted by this utility model to solve its technical problem is a punching device for steel processing, including an operating table. A drive cylinder providing power is bolted inside the operating table, and a drive block is screwed to the power output end of the drive cylinder. A limiting frame for moving steel is screwed to the outside of the drive block, and a double-headed cylinder providing power is bolted inside the limiting frame. Limit plates A and B are symmetrically screwed to the power output ends of the double-headed cylinder, with limiting plate A located to the left of limiting plate B. A drive assembly for moving steel on the operating table is provided at the bottom of the operating table. Fixing holes for punching the steel are opened on the surface of the operating table. A fixing frame is bolted to the outside of the operating table, and a hydraulic cylinder providing power is bolted to the inside of the fixing frame. A drive plate is screwed to the power output end of the hydraulic cylinder, and a punch rod for punching the steel is bolted to the inside of the drive plate. A buffer assembly for reducing the impact force of the drive plate is provided inside the operating table.

[0007] By adopting the above technical solution, when steel is to be punched, the steel is first placed in the operating table, and then the drive assembly at the bottom of the operating table moves the drive frame. The drive frame then moves the steel on the operating table. Subsequently, the double-headed cylinder in the limit frame is driven by the external controller to move the limit plate A and the limit plate B, so that the limit plate A and the limit plate B clamp the steel. Then, the drive cylinder in the operating table is driven by the external controller to move the limit frame on one side of the drive block. Subsequently, the limit frame moves the steel fixed inside, which facilitates the adjustment of the position of the steel and improves the punching efficiency of the steel.

[0008] After the steel position is adjusted, the hydraulic cylinder inside the fixed frame is driven by external control to move the drive plate, so that the punch rod inside the drive plate punches holes in the steel on the operating table. Then, one end of the punch rod enters the fixed hole opened on the surface of the operating table, and the debris generated by punching enters the box under the operating table for collection.

[0009] The fixing hole is located in the middle of the operating panel, and the drive cylinder is located inside the operating panel on one side, without overlapping with the fixing hole, so that the punch can pass smoothly through the fixing hole.

[0010] Specifically, the drive assembly includes a servo motor, a lead screw, a transmission block, a synchronous belt, a gear, and a drive frame. The servo motor, which provides power, is bolted to the outside of the operating table, and the power output end of the servo motor is keyed to the lead screw. The transmission block is threaded to the outside of the lead screw, and the drive frame, which drives the steel to move, is welded to the outside of the transmission block. A gear is sleeved on the outside of the lead screw, and the synchronous belt, which meshes with the outside of the gear, provides transmission.

[0011] By adopting the above technical solution, when the position of the steel on the operating table needs to be adjusted, the servo motor on one side of the operating table is driven by the external controller to rotate the lead screw. The gear on the outside of the lead screw drives the synchronous belt to rotate. There are two sets of gears, lead screws and transmission blocks at the bottom of the operating table. Then, the lead screw on the other set of gears is driven to rotate synchronously. Then, the external structure of the transmission block outside the lead screw moves laterally, so that the two sets of transmission blocks drive the drive frame to move synchronously. Then, the drive frame drives the steel on the operating table to move, which facilitates the adjustment of the position of the steel.

[0012] Specifically, the buffer assembly includes a damping spring, a buffer sleeve, a buffer rod, a rubber block, and a buffer plate. The damping spring is welded inside the operating table, and a buffer plate is welded to the end of the damping spring away from the operating table. Buffer sleeves are symmetrically welded to the outside of the buffer plate, and a buffer rod is slidably connected to the inside of the buffer sleeve.

[0013] By adopting the above technical solution, when the drive plate drives the punch rod to punch holes in the steel in the operating table, the drive plate contacts the buffer plate. Then, the buffer sleeves symmetrically welded on the outside of the buffer plate slide outside the buffer rod. Then, the buffer plate presses the damping spring in the operating table, so that the impact force of the drive plate moving downward is buffered, reducing the impact force of the drive plate moving downward, thereby facilitating the protection of the steel in the operating table.

[0014] Specifically, the buffer plate is secured with external screws to a rubber block that reduces impact.

[0015] By adopting the above technical solution, when the drive plate presses against the buffer plate, the rubber block outside the buffer plate comes into contact with the drive plate, reducing the downward impact force of the drive plate.

[0016] Specifically, connecting sleeves are welded to the ends of both the limiting plate A and the limiting plate B, and a support rod is slidably connected to the inner side of the connecting sleeve.

[0017] By adopting the above technical solution, when the limiting plate A and the limiting plate B move, the connecting sleeves at the ends of the limiting plate A and the limiting plate B slide outside the support rod, thereby improving the stability of the movement of the limiting plate A and the limiting plate B.

[0018] Specifically, the input terminals of the servo motor, hydraulic cylinder, and double-headed cylinder are all electrically connected to the power supply terminal of an external power source.

[0019] By adopting the above technical solution and connecting to an external power source, the electrical equipment can operate normally.

[0020] The beneficial effects of this utility model are:

[0021] The present invention discloses a punching device for steel processing. When punching steel is to be processed, the steel is placed in the operating table. Then, the drive assembly at the bottom of the operating table drives the drive frame to move, and the drive frame drives the steel on the operating table to move. Subsequently, the double-headed cylinder in the limiting frame is driven by the external controller to move the limiting plate A and the limiting plate B, so that the limiting plate A and the limiting plate B clamp the steel. Then, the drive cylinder in the operating table is driven by the external controller to move the limiting frame on one side of the drive block. Subsequently, the limiting frame drives the steel fixed inside to move, thereby facilitating the adjustment of the position of the steel and improving the punching efficiency of the steel.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To improve the efficiency of punching steel, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the punching device for steel processing of this utility model includes an operating table 8. A drive cylinder 26, providing power, is bolted inside the operating table 8. A drive block 25 is screwed to the power output end of the drive cylinder 26. A limiting frame 9, which moves the steel material, is screwed to the outside of the drive block 25. A double-headed cylinder 20, providing power, is bolted inside the limiting frame 9. Limit plates A21 and B24 are symmetrically screwed to the power output end of the double-headed cylinder 20. Limit plate A21 is located at the limiting position. On the left side of plate B24, a drive assembly 19 is provided at the bottom of the operating table 8 to move the steel on the operating table 8. The surface of the operating table 8 is provided with a fixing hole 7 for punching the steel. The operating table 8 is bolted to a fixing frame 1, and the fixing frame 1 is bolted to a hydraulic cylinder 2 that provides power. The power output end of the hydraulic cylinder 2 is screwed to a drive plate 3, and the drive plate 3 is bolted to a punch rod 4 for punching the steel. The operating table 8 is provided with a buffer assembly 27 to reduce the impact force of the drive plate 3.

[0031] When using the equipment, if steel is to be punched, the steel is first placed in the operating table 8. Then, the drive assembly 19 at the bottom of the operating table 8 drives the drive frame 10 to move. The drive frame 10 then moves the steel on the operating table 8. Subsequently, the double-headed cylinder 20 in the limit frame 9 is driven by the external controller to move the limit plate A21 and the limit plate B24, so that the limit plate A21 and the limit plate B24 clamp the steel. Then, the drive cylinder 26 in the operating table 8 is driven by the external controller to move the limit frame 9. Subsequently, the limit frame 9 moves the steel fixed on the inner side, which facilitates the adjustment of the position of the steel and improves the punching efficiency of the steel.

[0032] After the steel position is adjusted, the hydraulic cylinder 2 in the fixed frame 1 is driven by the external control to move the drive plate 3, so that the punch rod 4 in the drive plate 3 punches holes in the steel on the operating table 8. Then, one end of the punch rod 4 enters the fixed hole 7 opened on the surface of the operating table 8, and the debris generated by punching enters the box below the operating table 8 for collection.

[0033] The fixing hole 7 is located in the middle of the operating table 8, and the driving cylinder 26 is located inside the operating table 8 on one side, without overlapping with the fixing hole 7, so that the punch 4 can pass smoothly through the fixing hole 7.

[0034] To adjust the position of the steel, for example, such as Figure 1 , Figure 2As shown, this utility model also includes the following: the drive assembly 19 includes a servo motor 15, a lead screw 11, a transmission block 13, a synchronous belt 12, a gear 14, and a drive frame 10. The servo motor 15, which provides power, is bolted to the outside of the operating table 8, and the lead screw 11 is keyed to the power output end of the servo motor 15. The transmission block 13 is threaded to the outside of the lead screw 11, and the drive frame 10, which drives the steel to move, is welded to the outside of the transmission block 13. The gear 14 is sleeved on the outside of the lead screw 11, and the synchronous belt 12, which provides transmission, is meshed with the outside of the gear 14.

[0035] When adjusting the position of the steel on the operating table 8, the servo motor 15 on one side of the operating table 8 is driven by the external controller to rotate the lead screw 11. The gear 14 on the outside of the lead screw 11 drives the synchronous belt 12 to rotate. The gear 14, lead screw 11 and transmission block 13 at the bottom of the operating table 8 are all provided in two sets. Then the synchronous belt 12 drives the lead screw 11 on the other set of gears 14 to rotate. Then the external structure of the transmission block 13 outside the lead screw 11 moves laterally, so that the two sets of transmission blocks 13 synchronously drive the drive frame 10 to move. Then the drive frame 10 drives the steel on the operating table 8 to move, which facilitates the adjustment of the position of the steel.

[0036] To protect the steel on the workbench 8, for example, such as Figure 3 As shown, the present invention also includes the following: the buffer assembly 27 includes a damping spring 18, a buffer sleeve 17, a buffer rod 16, a rubber block 5, and a buffer plate 6. The damping spring 18 is welded inside the operating table 8, and the buffer plate 6 is welded to the end of the damping spring 18 away from the operating table 8. The buffer sleeve 17 is symmetrically welded to the outside of the buffer plate 6, and the buffer rod 16 is slidably connected to the inside of the buffer sleeve 17.

[0037] When adjusting the position of the steel on the operating table 8, the servo motor 15 on one side of the operating table 8 is driven by the external controller to rotate the lead screw 11. The gear 14 on the outside of the lead screw 11 drives the synchronous belt 12 to rotate. The gear 14, lead screw 11 and transmission block 13 at the bottom of the operating table 8 are all provided in two sets. Then the synchronous belt 12 drives the lead screw 11 on the other set of gears 14 to rotate. Then the external structure of the transmission block 13 outside the lead screw 11 moves laterally, so that the two sets of transmission blocks 13 synchronously drive the drive frame 10 to move. Then the drive frame 10 drives the steel on the operating table 8 to move, which facilitates the adjustment of the position of the steel.

[0038] To reduce the downward impact force on the drive board 3, for example, such as Figure 3 As shown, the present invention also includes a rubber block 5 for reducing impact force, which is fixed to the outside of the buffer plate 6 by screws.

[0039] When in use, when the drive plate 3 presses against the buffer plate 6, the rubber block 5 outside the buffer plate 6 comes into contact with the drive plate 3, reducing the downward impact force of the drive plate 3.

[0040] To improve the stability of the movement of limit plate A21 and limit plate B24, for example, as follows: Figure 4 As shown, the present invention also includes connecting sleeves 22 welded to the ends of both the limiting plate A21 and the limiting plate B24, and a support rod 23 is slidably connected to the inner side of the connecting sleeve 22.

[0041] When in use, as the limiting plate A21 and the limiting plate B24 move, the connecting sleeves 22 at the ends of the limiting plate A21 and the limiting plate B24 slide outside the support rod 23, thereby improving the stability of the movement of the limiting plate A21 and the limiting plate B24.

[0042] For electrical equipment to function properly, for example, such as Figure 1 , Figure 2 and Figure 4 As shown, this utility model also includes the fact that the input ends of the servo motor 15, the hydraulic cylinder 2, and the double-headed cylinder 20 are all electrically connected to the power supply end of an external power source.

[0043] When in use, the electrical equipment works normally by connecting to an external power source.

[0044] When using this utility model, if steel is to be punched, the steel is first placed in the operating table 8. Then, the drive assembly 19 at the bottom of the operating table 8 drives the drive frame 10 to move. The drive frame 10 then moves the steel on the operating table 8. Subsequently, the double-headed cylinder 20 in the limiting frame 9 is driven by the external controller to move the limiting plate A21 and the limiting plate B24, so that the limiting plate A21 and the limiting plate B24 clamp the steel. Then, the drive cylinder 26 in the operating table 8 is driven by the external controller to move the limiting frame 9. Subsequently, the limiting frame 9 moves the steel fixed on the inner side, thereby facilitating the adjustment of the position of the steel and improving the punching efficiency of the steel.

[0045] After the steel position is adjusted, the hydraulic cylinder 2 in the fixed frame 1 is driven by the external control to move the drive plate 3, so that the punch rod 4 in the drive plate 3 punches holes in the steel on the operating table 8. Then, one end of the punch rod 4 enters the fixed hole 7 opened on the surface of the operating table 8, and the debris generated by punching enters the box below the operating table 8 for collection.

[0046] The fixing hole 7 is located in the middle of the operating table 8, and the driving cylinder 26 is located inside the operating table 8 on one side, without overlapping with the fixing hole 7, so that the punch 4 can pass smoothly through the fixing hole 7.

[0047] When the position of the steel on the operating table 8 needs to be adjusted, the servo motor 15 on one side of the operating table 8 is driven by the external controller to rotate the lead screw 11. The gear 14 on the outside of the lead screw 11 drives the synchronous belt 12 to rotate. The gear 14, lead screw 11 and transmission block 13 at the bottom of the operating table 8 are all provided with two sets. Then the synchronous belt 12 drives the lead screw 11 on the other set of gears 14 to rotate. Then the external structure of the transmission block 13 outside the lead screw 11 moves laterally, so that the two sets of transmission blocks 13 synchronously drive the drive frame 10 to move. Then the drive frame 10 drives the steel on the operating table 8 to move, which makes it easier to adjust the position of the steel.

[0048] Bearings are provided at the end of the lead screw 11 that contacts the operating table 8 to ensure stable rotation of the lead screw 11;

[0049] When the drive plate 3 drives the punch rod 4 to punch holes in the steel inside the operating table 8, the drive plate 3 contacts the buffer plate 6, and the rubber block 5 outside the buffer plate 6 contacts the drive plate 3, reducing the downward impact force of the drive plate 3. Then, the buffer sleeve 17 symmetrically welded to the outside of the buffer plate 6 slides outside the buffer rod 16. Then, the buffer plate 6 presses the damping spring 18 inside the operating table 8, so that the impact force of the drive plate 3 moving downward is buffered, reducing the impact force of the drive plate 3 moving downward, thereby facilitating the protection of the steel on the operating table 8.

[0050] When the limiting plate A21 and the limiting plate B24 move, the connecting sleeve 22 at the ends of the limiting plate A21 and the limiting plate B24 slides outside the support rod 23, thereby improving the stability of the movement of the limiting plate A21 and the limiting plate B24.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
