Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, and particularly relates to a horizontal steel plate feeding device for a punching machine. Background Art

[0002] A punching machine is a device for punching steel plates into sheets. However, during the feeding process of the punching machine, manual feeding is generally used, which has complex operations and high labor costs. During the specific operation process, due to the certain weight of the steel plate itself, the steel plate is severely damaged by friction during the punching process.

[0003] Moreover, during the punching process, to ensure the full utilization of the steel plate material, usually after feeding forward for a certain distance, the steel plate is controlled to move left and right and then punched again, and then fed forward again. However, manual operation cannot ensure the stable movement of the steel plate during the punching process, and the steel plate is prone to a certain offset during the punching process, which affects the quality and effect of punching. Summary of the Utility Model

A slideway is formed between two adjacent support plates and the feeding table, and a slider is slidably fitted inside the slideway. A clamping mechanism for clamping the steel plate is arranged on the slider, and a driving motor for driving the clamping mechanism to move back and forth is arranged inside the slider.

[0007] In the above horizontal steel plate feeding device for a punching machine, the driving mechanism includes a ball screw installed on the frame. The ball screw is in threaded fit with the feeding table, and one end of the ball screw is connected to a rotary motor arranged on the frame.

[0015] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0016] A horizontal steel plate feeding device for a punching machine, as Figures 1 to 2 shown, includes a frame 1. A feeding table 2 is slidably installed on the top of the frame 1. Slide rails 10 for slidably fitting with the feeding table 2 are arranged on both sides of the frame 1. A driving mechanism for driving the feeding table 2 to move left and right is arranged on the frame 1. A plurality of support plates 3 are installed on the feeding table 2. A clamping mechanism 7 for clamping the steel plate is slidably installed between two adjacent support plates 3.

[0017] The driving mechanism includes a ball screw 8 installed on the frame 1. The ball screw 8 is threadedly fitted with the feeding table 2. One end of the ball screw 8 is connected to a rotating motor 9 arranged on the frame 1. By driving the ball screw to rotate by the rotating motor, the movement of the feeding table 1 is achieved.

[0018] A number of ball bearings 4 are also provided on the support plate 3 to cooperate with the clamping mechanism 7 to support the steel plate, which can reduce the friction between the steel plate and the support plate 3.

[0019] The end of the support plate 3 close to the punching machine is provided with an arc-shaped structure, which is convenient for the steel plate to move towards the punching machine.

[0020] A slideway 5 is formed between two adjacent support plates 3 and the feeding table 2. A slider 6 is slidably fitted inside the slideway 5. The clamping mechanism 7 is arranged on the slider 6, and a driving motor for driving the clamping mechanism 7 to move back and forth is arranged inside the slider 6.

[0021] The clamping mechanism 7 includes a lower clamping block 11 mounted on the slider 6 and an upper clamping block 12 hinged to the lower clamping block 11 through a hinge shaft 13. A pressing air cylinder 14 is also mounted on the top of the upper clamping block 12. By starting the pressing air cylinder 14 to press the upper clamping block 12 downward, the steel plate is clamped.

[0022] A torsion spring is also mounted on the hinge shaft 13, which can drive the upper clamping block 12 to automatically reset to complete the clamping of the steel plate.

[0023] During use, first, the clamping mechanism 7 is moved to a suitable position according to the size of the steel plate to be punched. Then, the pressing air cylinder 14 is started to press the upper clamping plate 12 downward, and the steel plate is placed between the upper clamping plate 12 and the lower clamping plate 11. The air cylinder is closed, and the upper clamping plate 12 automatically rebounds under the action of the torsion spring to cooperate with the lower clamping plate 11 to clamp the steel plate.

[0024] Then, the motor inside the slider is started to drive the clamping mechanism to clamp the steel plate and move it towards the punching machine, and cooperate with the ball bearings on the support plate to complete the conveying of the steel plate.

[0025] When the steel plate needs to be moved left and right, the rotary motor 9 is started to rotate the ball screw 8, driving the moving table 2 to drive the steel plate to move left and right to complete the punching in the left and right directions. Then, the steel plate is fed forward through the clamping mechanism, and the above operations are repeated until the steel plate punching is completed.

[0026] The utility model provides a horizontal steel plate feeding device for a punching machine. Through the cooperation of the clamping mechanism slidably arranged on the moving table and the ball bearings on the two side support plates, the stable feeding in the front and back directions is realized. Also, by setting a driving mechanism to drive the moving table to move left and right and cooperate with the slide rail, the stable feeding of the steel strip in the left and right directions is realized, ensuring the stability in the feeding process, improving the feeding efficiency, and reducing the frictional damage to the surface of the steel plate by setting the ball bearings.
