[0005] The aforementioned patents do not facilitate the collection of punched waste, resulting in the need for manual cleaning of the waste, which is time-consuming and labor-intensive. Therefore, we propose a punching device for steel channels in angle steel production to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem of the inconvenience of collecting the punched waste, which leads to the need for manual cleaning of the waste, which is time-consuming and labor-intensive. Therefore, a punching device for steel channels in angle steel production is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A punching device for producing steel channels in angle steel production, comprising:

[0009] Multiple support legs and a worktable mounted on top of the support legs, with a vertical discharge hole on the worktable;

[0010] The positioning table is fixedly installed on the top of the workbench. The top of the positioning table is triangular. The positioning table is used to initially position the angle steel that needs to be punched.

[0011] A groove is provided at the bottom of the positioning platform;

[0012] Both through holes are connected to the groove, and the two through holes are respectively located on the two inclined surfaces of the positioning platform;

[0013] The bridge-shaped plate is fixedly installed on the top of the workbench. The bridge-shaped plate is equipped with a punching mechanism and a clamping mechanism.

[0014] A collection box with an open top is located below the workbench to collect waste materials falling from the discharge hole.

[0015] Preferably, the clamping mechanism includes two lifting rods, and two guide vertical holes are opened on the top of the bridge plate. The two lifting rods are slidably installed in the two guide vertical holes respectively, and the same pressure plate is fixedly installed at the bottom of the two lifting rods.

[0016] Preferably, the bottom of the pressure plate is provided with an inverted V-shaped opening, and the pressure plate presses down the top of the angle steel through the inverted V-shaped opening.

[0017] Preferably, a cylinder is fixedly installed on the top of the bridge plate, and the output shaft of the cylinder is fixedly connected to the top of the pressure plate.

[0018] Preferably, the punching mechanism includes two mounting brackets fixedly mounted on the bridge plate, each mounting bracket having a hydraulic cylinder fixedly mounted on it, and each hydraulic cylinder having a punch fixedly mounted on its output shaft. The two punches are respectively aligned with two through holes, and two through holes are formed on the bridge plate, with the output shafts of the two hydraulic cylinders passing through the two through holes respectively.

[0019] Preferably, the top of the workbench is provided with a rectangular groove, a rectangular seat is slidably installed in the rectangular groove, and a push plate is fixedly installed on the top of the rectangular seat. The push plate is used to push the angle steel to slide on the positioning table.

[0020] Preferably, a screw is rotatably mounted inside the rectangular groove, a motor is fixedly mounted on the outside of the worktable, the output shaft of the motor is fixedly connected to one end of the screw, and the screw is threadedly connected to the rectangular seat.

[0021] Preferably, a limiting groove is formed on one inner wall of the rectangular groove, and a limiting block is fixedly installed on one side of the rectangular seat. The outer side of the limiting block slides in contact with the inner wall of the limiting groove. The setting of the limiting block and the limiting groove ensures that the rectangular seat can only slide along the rectangular groove.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] By setting grooves and through holes in the positioning platform below, setting vertical discharge holes in the worktable, and placing a collection box below the worktable, the waste generated during the punching process can automatically fall into the collection box along a preset path (through hole → groove → discharge hole). This design effectively solves the problem of manual waste cleaning required by traditional devices, saving time and labor, maintaining a clean working environment, and reducing production downtime, thereby improving overall operational efficiency.

[0024] A triangular-shaped positioning platform is used for initial positioning of the angle steel, and the inverted V-shaped opening at the bottom of the pressure plate ensures a good fit with the top shape of the angle steel. A cylinder drives the pressure plate downwards, quickly and securely pressing angle steels of different sizes onto the inclined surface of the positioning platform. This effectively prevents the angle steel from moving or shaking during punching, ensuring punching accuracy and enhancing the device's adaptability to angle steel of different specifications.

[0033] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments.

[0034] Example 1:

[0035] Reference Figures 1-7 A punching device for angle steel production channels, comprising:

[0036] Multiple support legs 1 and a worktable 2 mounted on top of the multiple support legs 1, with a vertical discharge hole 3 provided on the worktable 2;

[0037] Positioning table 4 is fixedly installed on the top of workbench 2. The top of positioning table 4 is triangular. Positioning table 4 is used to initially position the angle steel 20 that needs to be punched.

[0038] Groove 6 is located at the bottom of positioning platform 4;

[0039] Both through holes 5 are connected to the groove 6, and the two through holes 5 are respectively located on the two inclined surfaces of the positioning platform 4;

[0040] Bridge plate 7 is fixedly installed on the top of workbench 2. Bridge plate 7 is equipped with a punching mechanism and a clamping mechanism.

[0041] A collection box 13 with an open top is located below the workbench 2 to collect waste materials falling from the discharge hole 3.

[0042] In this embodiment, the clamping mechanism includes two lifting rods. Two guide vertical holes are opened on the top of the bridge plate 7. The two lifting rods are slidably installed in the two guide vertical holes respectively. The same pressure plate 12 is fixedly installed at the bottom of the two lifting rods.

[0043] In this embodiment, the bottom of the pressure plate 12 is provided with an inverted V-shaped opening 14, and the pressure plate 12 presses down the top of the angle steel 20 through the inverted V-shaped opening 14.

[0044] In this embodiment, a cylinder 11 is fixedly installed on the top of the bridge plate 7, and the output shaft of the cylinder 11 is fixedly connected to the top of the pressure plate 12.

[0045] In this embodiment, the punching mechanism includes two mounting brackets 8 fixedly installed on the bridge plate 7. A hydraulic cylinder 9 is fixedly installed on each of the two mounting brackets 8. A punch 10 is fixedly installed on the output shaft of each of the two hydraulic cylinders 9. The two punches 10 are respectively aligned with two through holes 5. Two through holes are opened on the bridge plate 7. The output shafts of the two hydraulic cylinders 9 pass through the two through holes respectively.

[0046] In this embodiment, a rectangular groove 15 is provided on the top of the workbench 2, and a rectangular seat 16 is slidably installed in the rectangular groove 15. A push plate 17 is fixedly installed on the top of the rectangular seat 16, and the push plate 17 is used to push the angle steel 20 to slide on the positioning table 4.

[0047] In this embodiment, a screw 19 is rotatably installed inside the rectangular groove 15, and a motor 18 is fixedly installed on the outside of the workbench 2. The output shaft of the motor 18 is fixedly connected to one end of the screw 19, and the screw 19 is threadedly connected to the rectangular seat 16.

[0048] In this embodiment, a limiting groove is formed on one inner wall of the rectangular groove 15, and a limiting block is fixedly installed on one side of the rectangular seat 16. The outer side of the limiting block slides in contact with the inner wall of the limiting groove. The setting of the limiting block and the limiting groove allows the rectangular seat 16 to slide only along the rectangular groove 15.

[0049] Working principle:

[0050] The angle steel 20 to be processed is placed on the top inclined surface of the positioning platform 4. Since the top of the positioning platform 4 is triangular, it can provide initial positioning and support for the angle steel 20.

[0051] When the cylinder 11 is activated, its output shaft pushes the pressure plate 12 downward. The inverted V-shaped opening 14 at the bottom of the pressure plate 12 then descends and presses the top of the angle steel 20 onto the positioning table 4, thus clamping and fixing the angle steel 20 to prevent it from moving or shaking during the punching process.

[0052] Two hydraulic cylinders 9 are activated, and their output shafts drive the punch 10 to move downwards. The punch 10 passes through the perforation on the bridge plate 7 to punch the angle steel 20 located below it.

[0053] The circular waste generated by punching falls off the angle steel 20, passes through the through hole 5 on the positioning table 4 and falls into the groove 6 at its bottom. Then it falls vertically through the discharge hole 3 on the worktable 2 and is finally collected by the collection box 13 placed below the worktable 2, realizing the automatic cleaning of waste.

[0054] After completing one punching operation, hydraulic cylinder 9 drives punch 10 to retract, and air cylinder 11 drives pressure plate 12 to rise and release angle steel 20.

[0055] The motor 18 is started, and its output shaft drives the screw 19 to rotate. The rectangular seat 16, which is threaded to the screw 19, moves horizontally along the rectangular groove 15 under the guidance and constraint of the limiting block and the limiting groove, thereby driving the push plate 17 on its top to push the angle steel 20 to move along the positioning table 4 to perform punching operations in other positions.

[0056] Example 2:

[0057] The difference from Embodiment 1 is that: the two inclined surfaces of the positioning platform 4 are provided with anti-slip textures, and the inner side of the inverted V-shaped opening 14 is provided with anti-slip rubber strips to increase the stability when the diagonal steel 20 is fixed.

[0058] The rest is the same as in Example 1.

[0059] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0060] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
