Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal processing, and particularly relates to a high-precision building sheet metal punching device. Background Art

[0002] In the construction industry, steel structures are the main supports and connectors. Among them, steel sheets are one of the main components of steel structures. According to different uses, the sheets usually need to be processed by stamping, punching, bending, etc., so that the sheets meet the usage requirements.

[0003] Chinese Patent with the publication number CN219253887U discloses a guiding device for a sheet metal punching machine, which includes a workbench. The workbench is connected with a C-shaped plate, the C-shaped plate is connected with a hydraulic device, the output end of the hydraulic device is slidably connected with the C-shaped plate, the output end of the hydraulic device is connected with two groups of symmetrical guiding mechanisms, the workbench is slidably connected with two groups of symmetrical pressing mechanisms, the workbench is provided with a through hole, and the through hole is correspondingly arranged with the output end of the hydraulic device. The guiding mechanism includes a contact plate connected to the outer peripheral side of the output end of the hydraulic device. One end of the contact plate away from the workbench is connected with a guide rod, the guide rod is connected with a fixing screw, the fixing screw is threadedly connected with a rotating threaded sleeve, the rotating threaded sleeve is connected with a rotating handle, and one end of the rotating threaded sleeve close to the C-shaped plate is connected with a contact spring, and the contact spring is arranged outside the guide rod. The above scheme can adjust the punching stroke of the punching machine and also can play a buffering role after punching, improving the safety factor.

[0004] However, in the actual use process, although the pressing mechanism can press the sheet metal and limit and guide the sheet metal on both sides, the above scheme cannot limit and guide the sheet metal in the conveying direction of the sheet metal, resulting in the need to manually adjust the position of the sheet metal relative to the through hole before stamping and punching to ensure that the sheet metal after stamping and punching meets the usage requirements. This method is labor-consuming and has low precision, which is not conducive to use. Summary of the Utility Model

[0005] The utility model aims to provide a high-precision building sheet metal punching device to solve the problem of low precision of the above scheme.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A high-precision building sheet metal punching device includes

[0007] A workbench, above which a stamping and punching mechanism is installed. The workbench is provided with a forming hole corresponding to the stamping and punching mechanism, and a storage box corresponding to the forming hole is installed at the bottom of the workbench;

[0008] The limiting mechanism includes two limiting plates with a 7-shaped cross-section, a guide slide plate, and a pressing unit. The two limiting plates are slidably arranged on the workbench and symmetrically arranged on both sides of the feeding direction. The pressing unit is installed on the top of the limiting plates. The guide slide plate is fixed on the workbench and located at the end of the feeding direction. A guide sliding surface is made on the top of the guide slide plate on the side close to the forming hole.

[0009] The lifting and supporting mechanism is used to lift the sheet during transportation, and the top edge of the lifting and supporting mechanism is not higher than the top edge of the guide slide plate.

[0010] The principle and effect of this technical solution:

[0011] 1. By restricting both sides of the workbench in the feeding direction through the limiting plates, the position of the sheet on the workbench is restricted, so that the sheet can only move along the feeding direction. When the lifting and supporting mechanism lifts the sheet, after the sheet moves to contact the guide slide plate, when the pressing unit drives the sheet to press down, the sheet can be driven by the guide sliding surface of the guide slide plate, so as to correct the sheet, making the punching and opening accuracy on the final sheet higher. The setting of the punching and opening mechanism can punch and open the sheet.

[0012] 2. The lifting and supporting mechanism can lift the sheet when it moves, thus reducing the contact area between the sheet and the workbench, making the workbench not easy to wear. And because the lifting and supporting mechanism can be lifted and lowered, when the sheet is placed on the lifting and supporting mechanism, it can be pressed down by the pressing unit, so as to drive the sheet to move along the guide slide plate, so that the guide slide plate can play the function of guiding and limiting.

[0013] The present utility model is further configured as: the punching and opening mechanism includes an inverted U-shaped fixed frame, a hydraulic cylinder, a protection plate, and a punching rod. The fixed frame is fixed on the workbench, and one section of the limiting plate is located inside the fixed frame. The hydraulic cylinder is fixed on the fixed frame. The hydraulic rod of the hydraulic cylinder passes through the fixed frame and is fixed to the punching rod. The protection plate is installed at the bottom of the fixed frame and is slidably sleeved on the punching rod. The punching rod is adapted to the forming hole.

[0014] The principle and effect of this technical solution: The hydraulic cylinder drives the punching rod to move up and down, so that the punching rod can cooperate with the forming hole to complete the punching and opening of the sheet. The setting of the protection plate can guide and limit the punching rod, making the punching rod more durable and reliable.

[0015] The present utility model is further configured as: the pressing unit includes two pressing components respectively arranged on the two limiting plates. The pressing component includes an electric push rod and a pressing plate. The electric push rod is fixed on the limiting plate. The bottom of the electric push rod passes through the top of the limiting plate and is fixed to the pressing plate. The pressing plate slides inside the limiting plate.

[0016] The principle and effect of this technical solution: the electric push rod drives the pressure plate to press down, so that the two sides of the plate are pressed by the pressure plate to drive the lifting and supporting mechanism to descend, so that the plate can be stably placed on the work table, and when the plate descends, it is guided by the guide surface, so that the plate can be moved to the specified position for punching and opening, and the electric push rod can stably press the plate on the work table.

[0017] The utility model is further configured as follows: the limiting mechanism also includes a control unit, the control unit includes a motor, a bidirectional screw and two nut seats, a control groove is opened on the workbench perpendicular to the feeding direction, the bidirectional screw is rotatably installed in the control groove, and one end of the bidirectional screw is fixed to the rotating end of the motor, the motor is installed on the side wall of the workbench, the two nut seats are respectively fixed to the bottom of the two limiting plates, the nut seats are threadedly mounted on the bidirectional screw, and the nut seats are slidably fitted in the control groove.

[0018] The principle and effect of this technical solution: the bidirectional screw is driven to rotate by a motor, so that the nut seat can drive the limit plate to slide relative to the workbench, thereby changing the distance between the two limit plates, so that the workbench can guide, limit and clamp plates of different widths, thereby making the device more applicable.

[0019] The utility model is further configured as follows: the control unit also includes a guide rod and a guide block, a guide groove symmetrical to the control groove is opened on the workbench, the guide rod is fixed in the guide groove, a guide block is fixed at the bottom of the limit plate, the guide block is slidably mounted on the guide rod, and the guide block is slidably matched with the guide groove.

[0020] The principle and effect of the technical solution: by setting the guide rod and the guide block, the limit plates on both sides are more stable when adjusting their positions on the workbench, thereby making the position of the limit plates more reliable.

[0021] The utility model is further configured as follows: the lifting and lowering supporting mechanism includes a supporting frame, a supporting rod, a spring and a limit block, a makeshift groove adapted to the supporting frame is opened on the workbench, a plurality of supporting rods are evenly arranged on the bottom of the supporting frame, a plurality of makeshift holes corresponding to the supporting rods are opened in the makeshift groove, the supporting rods are slidably inserted in the makeshift holes, and the bottom of the supporting rods extends to below the bottom of the workbench and is fixed to the limit block, the spring is sleeved on the supporting rod and is located between the supporting frame and the workbench.

[0022] The principle and effect of this technical solution are as follows: the support rack is driven away from the workbench by the spring, so that the support rack lifts the plate, so that the plate can leave the workbench during transportation, and after moving to abut against the guide slide plate, the clamping unit is pressed down to apply pressure on both sides of the plate, so that the plate drives the support rack to move down, thereby contracting the spring until the support rack is in the yield groove and the plate is pressed tightly against the workbench, so that a hole can be punched, and in the process of pressing the plate down, since the side of the plate close to the guide slide plate abuts against the guide slide surface, the plate will be driven by the guide slide surface during the pressing process, so that the plate slides to the specified position, thereby avoiding the misalignment of the hole caused by improper placement when punching the plate, and the setting of the limit block prevents the support rod from detaching from the yield hole, improves the stability of the device, and the spring can spontaneously raise the support rack, thereby realizing the function of automatic resetting.

[0023] The utility model is further configured as follows: a plurality of supporting rollers are evenly arranged on the inner side of the supporting frame along the feeding direction.

[0024] The principle and effect of this technical solution: The setting of the support roller changes the sliding friction of the plate into rolling friction when it moves, thereby reducing the friction between the support frame and the plate, making the plate less prone to wear during processing, thereby ensuring the quality of the plate.

There are two guide rods 307 which are respectively fixed in the guide grooves 105 on both sides. A guide block is fixed to the bottom of the limiting plate 301. The guide block is slidably sleeved on the guide rod 307 and is slidably matched with the guide groove 105. Among them, the nut seats and the guide blocks are not marked in the figure, but are well-known components in the art and do not need to be described in detail.

[0035] The two limit plates 301 slide on the workbench 101 and are symmetrically arranged on both sides of the feeding direction. The clamping unit includes two clamping assemblies respectively arranged on the two limit plates 301. The clamping assembly includes an electric push rod 303 and a pressure plate 304. The electric push rod 303 is fixed on the limit plate 301. The bottom of the electric push rod 303 passes through the top of the limit plate 301 and is fixed to the pressure plate 304.

[0037] The specific implementation process is as follows:

[0038] When using this device, after placing the plate on the material supporting roller 405 of the material supporting frame 401, start the motor 305 according to the width of the plate, so that the motor 305 drives the nut seat to move, thereby driving the position change of the limiting plates 301 on both sides, so that the limiting plates 301 guide and limit both sides of the plate, and then convey the plate along the feeding direction until the plate abuts against the guide slide plate 302, then stop the conveying of the plate, and then start the electric push rod 303 at this time to make the pressing plate 304 press down, so that the pressing plate 304 drives the plate to press down. During this process, the plate is positionally corrected through the guiding surface of the guide slide plate 302, and the plate transfers the pressure to the material supporting roller 405, so that the material supporting roller 405 presses down the spring 403 and the material supporting rod 402 presses down until the plate is tightly pressed on the working table 101 surface. Then start the hydraulic cylinder 202, and then make the hydraulic rod 203 drive the punching rod 205 to punch down, so as to complete the punching and opening process of the plate. Then the punching rod 205 resets, and the pressing unit resets. The rebounding force of the spring 403 drives the material supporting frame 401 to reset, and then continue to convey the plate, that is, the plate can cross the guide slide plate 302, so that the plate is separated from the working table 101 surface. A storage device can be placed on the side of the guide slide plate 302 away from the punching rod 205 to store the plate after the punching and opening is completed, or it can be manually lifted and stored. The above are only the embodiments of the present invention, and common general technical solutions or characteristics and the like in the solution are not described in detail herein.

[0039] It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
