Description

Technical Field

[0001] The utility model belongs to the technical field of precision four-column hydraulic cutting machines, and particularly relates to a clamping device for a precision four-column hydraulic cutting machine. Background Art

[0002] Hydraulic precision four-column cutting machines are widely used in the cutting and processing processes of industries such as handbags, luggage, shoes, leather goods, silk flowers, foam, blister, plush toys, sports goods, automotive supplies, and EVA.

[0003] When the existing cutting machine is in use, the material to be cut is usually placed on the workbench and then directly cut. In this way, during the cutting process, after the cutting tool contacts the material, the material is likely to shift, and it does not have the function of pressing from the top. Therefore, during the cutting process, the material is likely to warp, affecting the cutting effect. For this reason, we propose a clamping device for a precision four-column hydraulic cutting machine. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a clamping device for a precision four-column hydraulic cutting machine. By setting a pressing component, specifically, when the cutting die moves downward, the bottom of the pressing seat will first contact the cutting material. Through continuous downward pressing, the pressing seat will slide within the cutting die. At the same time, the connecting plate slides on the limiting rod and squeezes the spring, so that the cutting material is clamped and fixed. At the same time, the cutting material is fixed from the top, which can avoid the situation of shifting or warping during cutting, improve the cutting effect, and solve the problem that the existing cutting machine does not have the function of pressing from the top, so that the material is likely to warp during the cutting process, affecting the cutting effect.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a clamping device for a precision four-column hydraulic cutting machine, which includes a cutting machine box body. The top of the cutting machine box body is fixedly connected with a top seat. The inside of the top seat is provided with a cavity. The top of the top seat is fixedly connected with a hydraulic cylinder. The output end of the bottom of the hydraulic cylinder is fixedly connected with a cutting die. The bottom of the cutting die is fixedly connected with a cutting knife. A pressing component is arranged inside the top seat. A workbench is arranged on the top of the cutting machine box body. A cutting opening is formed on the top of the workbench. A cutting material is in contact with the top of the workbench. A leveling component is arranged on the front of the cutting die;

[0007] The pressing assembly includes a pressing seat. A groove is formed at the top of the pressing seat. Two connecting plates are fixedly connected to the inner wall of the groove. The two connecting plates are symmetrically arranged with the hydraulic cylinder as the center. The parts included in the two connecting plates are the same. Two sliding holes are formed in the connecting plates. Limiting rods are slidably connected to the inner walls of the two sliding holes. Springs are sleeved on the outer sides of the two limiting rods. By providing the pressing assembly, the cutting material can be clamped and fixed through the pressing seat, and at the same time, the cutting material can be fixed from the top, which can avoid the situation of deviation or warping during cutting and improve the cutting effect.

[0008] Further, limiting holes are formed at the four corners of the cutting die. Supporting columns are slidably connected to the inner walls of the limiting holes. The bottoms of the supporting columns are fixedly connected to the top of the cutting machine box body. The tops of the supporting columns are fixedly connected to the inner top of the top seat. Two sliding grooves are formed at the top of the cutting machine box body. A limiting plate is fixedly connected to the top of the cutting machine box body. When the cutting die moves, it will slide on the supporting columns, which can play a role in limiting and stabilizing the cutting die. The sliding grooves can play a role in limiting the movement of the workbench.

[0009] Further, two sliders are fixedly connected to the bottom of the workbench. The outer surfaces of the sliders are in contact with the inner walls of the sliding grooves. The sliders are slidably connected to the sliding grooves. A handle is fixedly connected to the front of the workbench. The bottom of the workbench is in contact with the top of the cutting machine box body. The cutting knife is adapted to the cutting opening. The sliders at the bottom of the workbench slide in the sliding grooves. When the front surface of the slider is in contact with the front surface of the inner wall of the sliding groove, the workbench moves out of the top seat, which is convenient for the staff to take and place the cutting material. At the same time, the sliders can support the workbench.

[0010] Further, the flattening assembly includes an arc-shaped flattening plate. A first connecting rod is arranged above the arc-shaped flattening plate. First supporting blocks are fixedly connected to the left and right sides of the first connecting rod. Two movable frames are fixedly connected to the outer surface of the first connecting rod. The parts included in the fronts of the two movable frames are the same. A rotating hole is formed at the top of the movable frame. A second connecting rod is rotatably connected to the inner wall of the rotating hole. By providing the flattening assembly, specifically, after the pressing seat is extruded, the arc-shaped flattening plate will contact the cutting material and slide on the cutting material towards the front, thereby flattening the cutting material, improving the cutting effect again, making the cutting accuracy higher, and reducing the occurrence of warping.

[0011] Further, support blocks II are fixedly connected to both the left and right sides of the second connecting rod. A shrapnel is arranged on the front surface of the movable frame. Fixing blocks are rotatably connected to both the top and bottom of the shrapnel. The top of the fixing block located above is fixedly connected to the top inner wall of the top seat, and the back of the fixing block located below is fixedly connected to the front surface of the movable frame. The bottom of the support block I is fixedly connected to the top of the arc-shaped flattening plate, and the back of the support block II is fixedly connected to the front surface of the cutting die. When the movable frame moves, it will squeeze the shrapnel, and under the action of elasticity, the arc-shaped flattening plate will be closely attached to the cutting material.

[0012] Further, a storage groove is formed at the bottom of the cutting die. The inner wall of the storage groove is in contact with the outer surface of the pressing seat. The bottom of the cutting die is slidably connected to the pressing seat through the storage groove. The top of the pressing seat is fixedly connected to the top inner wall of the storage groove. The top of the spring is fixedly connected to the top inner wall of the storage groove, and the bottom of the spring is fixedly connected to the top of the connecting plate. The back of the cutting knife is in contact with the front surface of the pressing seat. When the pressing seat moves, the connecting plate slides on the limiting rod and squeezes the spring. Under the action of elasticity, the pressing seat can be closely attached to the cutting material. At the same time, when the cutting die moves upward to reset, it is convenient for the pressing seat to reset downward under the action of elasticity.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting the pressing component, specifically, when the cutting die moves downward, the bottom of the pressing seat will first contact the cutting material. By continuously pressing down, the pressing seat will slide in the cutting die. At the same time, the connecting plate slides on the limiting rod and squeezes the spring, so that the cutting material is clamped and fixed, and the cutting material is fixed from the top, which can avoid the situation of deviation or warping during cutting and improve the cutting effect.

[0015] 2. By setting the flattening component, specifically, after the pressing seat is pressed, the arc-shaped flattening plate will contact the cutting material and slide forward on the cutting material, thereby flattening the cutting material. At the same time, the movable frame will squeeze the shrapnel, and under the action of elasticity, the arc-shaped flattening plate will be closely attached to the cutting material. By flattening the cutting material, the cutting effect can be improved again, making the cutting accuracy higher and reducing the occurrence of warping.

[0034] A specific application of this embodiment is:

[0035] When in use, first pull the handle 134 to drive the workbench 13 to move. Then, the slider 133 at the bottom of the workbench 13 slides in the chute 15. When the front surface of the slider 133 comes into contact with the front surface of the inner wall of the chute 15, the workbench 13 moves out of the top seat 11, facilitating the staff to place and take out the cutting material 132. After placing the cutting material 132 on the workbench 13, the workbench 13 can be pushed into the top seat 11. Subsequently, start the hydraulic cylinder 111 to drive the cutting die 112 to move downward. When the cutting die 112 moves, it slides on the support column 114. Then, the bottom of the pressure seat 121 will first contact the cutting material 132. Through continuous downward pressing, the pressure seat 121 slides in the cutting die 112. At the same time, the connecting plate 122 slides on the limiting rod 123 and squeezes the spring 124, so that the cutting material 132 is clamped and fixed. At the same time, the cutting material 132 is fixed from the top, which can avoid deviation or warping during cutting, improve the cutting effect. At the same time, after the pressure seat 121 is squeezed, the arc leveling plate 141 will contact the cutting material 132. Since the arc leveling plate 141 is arc-shaped, when pressing downward, the arc leveling plate 141 will slide forward on the cutting material 132, thereby leveling the cutting material 132. The arc leveling plate 141 drives the movable frame 144 to rotate on the connecting rod 145 through the support block 143 and the connecting rod 142, enabling the arc leveling plate 141 to slide smoothly. At the same time, the movable frame 144 squeezes the elastic piece 441, and under the elastic action, the arc leveling plate 141 is closely attached to the cutting material 132. By leveling the cutting material 132, the cutting effect can be improved again, making the cutting accuracy higher. Subsequently, through the continuous movement of the cutting die 112, the cutting material 132 is cut under the cooperation of the cutting knife 113 and the cutting opening 131. After cutting is completed, the hydraulic cylinder 111 drives the cutting die 112 to reset upward. Then, the pressure seat 121 resets under the elastic action of the spring 124, and the arc leveling plate 141 resets under the elastic action of the elastic piece 441, facilitating the next pressing and fixing.
