Description

Technical Field

[0001] This utility model belongs to the field of hydraulic cutting protection technology, specifically a protective structure for a hydraulic cutting machine. Background Technology

[0002] The four-column hydraulic cutting machine can be used in the leather processing industry, garment industry, bag manufacturing industry, packaging industry, toy industry, stationery industry, and automotive industry. By using a forming die, it can cut materials such as leather, rubber, cardboard, cloth, foam, nylon, artificial leather, and PVC board. It adopts a four-column and crank synchronous balancing mechanism to ensure uniform force distribution in the cutting area of ​​the machine tool.

[0003] A patent with publication number CN 218639808 U discloses a safety protection structure for a four-column hydraulic cutting machine, including a four-column hydraulic cutting machine body, a push-pull plate installed on the upper end of the four-column hydraulic cutting machine body, and a pad placed on the upper end of the push-pull plate. A limiting structure is provided at the upper front end of the push-pull plate. The limiting structure includes a U-shaped steel support frame, and the U-shaped steel support frame is located above the front end of the push-pull plate. In use, the limiting structure on the push-pull plate can press and limit the pad placed on the push-pull plate and the multi-layer board placed on the pad together, so that the pad and multi-layer board are not easy to move during the push-pull process, and thus the die is not easy to deflect due to the movement of the pad and multi-layer board after placement.

[0004] Currently, existing hydraulic cutting machines require manual placement of raw materials onto a conveyor belt. The cutting blade then continuously cuts the material. During this process, manual separation of the cut products and scraps is necessary. Existing hydraulic cutting machines employ various methods, including continuous cutting and worker-operated cutting. Continuous cutting can easily lead to workers' hands not being able to retract in time, potentially causing injury. Worker-operated cutting, located out of sight, is activated by stepping on the machine. However, as workers push the material forward, their unstable center of gravity can cause them to accidentally step on the switch, activating the machine.

[0005] Therefore, a protective structure for a hydraulic cutting machine is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, a protective structure for a hydraulic cutting machine is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The protective structure of the hydraulic cutting machine of this utility model includes a four-column hydraulic cutting machine and an overlapping conveyor table detachably installed on one side surface of the four-column hydraulic cutting machine. Limiting slide rods are fixedly installed on the inner walls of both sides of the overlapping conveyor table. The cutting material is movably sleeved on the top surface of the overlapping conveyor table. A slider is movably sleeved on the outer surface of the limiting slide rod. A snap-fit ​​groove is fixedly connected to the outer surface of the slider. A pull rod is detachably installed on the inner wall of the snap-fit ​​groove. A fitting overlapping plate is fixedly connected to one end of the pull rod. A motor is fixedly installed on one side surface of the fitting overlapping plate. A bidirectional threaded rod is fixedly connected to the output end of the motor and movably sleeved on the inner wall of the fitting overlapping plate. A rectangular slider is movably sleeved on the surface of the bidirectional threaded rod and at the two side edges. An L-shaped fitting plate is detachably installed on the outer surface of the rectangular slider and movably overlapped on the outer surface of the cutting material.

[0008] Preferably, four hydraulic rods are fixedly installed on the top surface of the four-column hydraulic cutting machine and at the two side edges, and a lower pressure table is fixedly installed on the output end of the four hydraulic rods.

[0009] Preferably, a hydraulic rod is fixedly installed on the bottom surface of the lower press platform at the middle position, and a connecting extrusion plate that is movably sleeved on the top surface of the cut raw material is fixedly connected to the output end of the hydraulic rod.

[0010] Preferably, a feeding conveyor is fixedly installed on the other side surface of the four-column hydraulic cutting machine, and a material discharge slot is provided at the connection between the feeding conveyor and the four-column hydraulic cutting machine.

[0011] Preferably, a chip collection groove is provided on one side surface of the four-column hydraulic cutting machine at the bottom edge of the feeding conveyor table, and a pressing cutting plate is detachably installed on one side surface of the pressing table at the top edge of the discharge chute.

[0012] Preferably, an L-shaped electromagnet is detachably installed on the inner wall of the L-shaped bonding plate, and a current-carrying device linearly connected to the outer surface of the L-shaped electromagnet is fixedly installed on one side surface of the L-shaped bonding plate.

[0013] Preferably, a groove is provided on the top surface of the overlapping conveyor table, and an auxiliary roller is provided on the inner wall of the groove, which is movably overlapped on the bottom surface of the cut raw material.

[0014] Preferably, the inner walls on both sides of the overlapping conveyor are provided with limiting grooves, and the inner wall of the limiting grooves wraps around the outer surface of the limiting slide rod.

[0015] The beneficial effects of this utility model are:

[0016] This utility model provides a protective structure for a hydraulic cutting machine. The neatly stacked raw materials are placed on the top surface of an overlapping conveyor table, and one side of the overlapping plate is attached to the surface of the raw materials, ensuring that one side of the raw materials remains neat. A motor connected to the overlapping plate rotates a bidirectional threaded rod, causing a rectangular slider on the outer surface of the threaded rod to move simultaneously in both directions on the inner wall of the overlapping plate, confined by the overlapping plate. While moving in the same direction, the rectangular slider presses and clamps the L-shaped overlapping plate on its outer surface onto the two corners of the raw materials. The L-shaped overlapping plate effectively confines the corners of the material. Pushing the pull rod further drives the overlapping plate, propelling the raw materials across the surface of the overlapping conveyor table.

[0017] This utility model provides a protective structure for a hydraulic cutting machine. While the raw material moves inside the four-column hydraulic cutting machine, the four-column hydraulic rods press down on the lower pressure table, causing the surface of the connecting extrusion plate to adhere to the surface of the raw material, thus compressing it tightly. Then, the lower cutting plate presses down further, cutting and trimming the exposed raw material. The trimmed debris enters the debris collection groove through the material drop chute and is collected. If some raw materials are relatively thin, after lowering the lower pressure table, the hydraulic rods push the connecting extrusion plate a second time, increasing the pressing distance of the connecting extrusion plate. This achieves the effect of effectively extruding and positioning raw materials of different thicknesses by changing the pressing distance of the connecting extrusion plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 - Figure 5This utility model provides a protective structure for a hydraulic cutting machine, including a four-column hydraulic cutting machine 11 and a detachable overlapping conveyor table 12 mounted on one side surface of the four-column hydraulic cutting machine 11. Limiting slide rods 13 are fixedly mounted on the inner walls of both sides of the overlapping conveyor table 12. Cutting material 14 is movably sleeved on the top surface of the overlapping conveyor table 12. A slider 131 is movably sleeved on the outer surface of the limiting slide rod 13. A snap-fit ​​groove 132 is fixedly connected to the outer surface of the slider 131. A pull rod 133 is detachably mounted on the inner wall of the snap-fit ​​groove 132. A fitting overlapping plate 134 is fixedly connected to one end of the pull rod 133. A motor 135 is fixedly mounted on one side surface of the fitting overlapping plate 134. A bidirectional threaded rod 136 is fixedly connected to the output end of the motor 135 and is movably sleeved on the inner wall of the overlapping plate 134. A rectangular slider 137 is movably sleeved on the surface of the bidirectional threaded rod 136 and at the two side edges. An L-shaped bonding plate 138 is detachably installed on the outer surface of the rectangular slider 137 and is movably overlapped on the outer surface of the cut material 14. A groove 121 is opened on the top surface of the overlapping conveyor table 12. An auxiliary roller 122 is provided on the inner wall of the groove 121 and is movably overlapped on the bottom surface of the cut material 14. Limiting grooves 123 are opened on the inner walls of both sides of the overlapping conveyor table 12. The inner wall of the limiting groove 123 is wrapped around the outer surface of the limiting slide rod 13.

[0028] During operation, neatly stacked cut materials 14 are placed on the top surface of the overlapping conveyor table 12, and one side surface of the overlapping plate 134 is attached to the surface of the cut materials 14, ensuring that one side surface of the cut materials 14 remains neat. The motor 135, which operates in conjunction with the overlapping plate 134, rotates the bidirectional threaded rod 136. This causes the rectangular slider 137 on the outer surface of the bidirectional threaded rod 136 to move simultaneously in the same and opposite directions on the inner wall of the overlapping plate 134, confined by the overlapping plate 134. While moving in the same direction, the rectangular slider 137 also moves in opposite directions. The L-shaped bonding plate 138 on the outer surface of block 137 is pressed and snapped onto the two corners of the cut material 14. At the same time, the L-shaped bonding plate 138 effectively limits the corner position of the material. Then, the pull rod 133 is pushed, which in turn drives the bonding overlap plate 134 to push the cut material 14 to move on the surface of the overlap conveyor table 12. If it is necessary to push some small materials with a short time distance, the pull rod 133 is pulled on the inner wall of the snap-fit ​​groove 132 to change the distance between the snap-fit ​​groove 132 and the bonding overlap plate 134, so that the pushing distance of the pull rod 133 is longer, and the cut material 14 can be pushed further.

[0029] Furthermore, such as Figures 1 to 3As shown, a four-column hydraulic cutting machine 11 has four hydraulic rods 111 fixedly installed on its top surface and at its two side edges. A lower pressure table 112 is fixedly installed on the output end of the four-column hydraulic rods 111. A hydraulic rod 113 is fixedly installed on the bottom surface of the lower pressure table 112 at its middle position. A connecting extrusion plate 114, which is movably sleeved on the top surface of the raw material 14 to be cut, is fixedly connected to the output end of the hydraulic rod 113. A feeding conveyor table 115 is fixedly installed on the other side surface of the four-column hydraulic cutting machine 11. The feeding conveyor table 115 and the four-column hydraulic cutting machine... A material drop trough 116 is provided at the connection of the cutting machine 11. A chip collection groove 117 is provided on one side surface of the four-column hydraulic cutting machine 11 at the bottom edge of the feeding conveyor table 115. A pressing cutting plate 118 is detachably installed on one side surface of the pressing table 112 at the top edge of the material drop trough 116. An L-shaped electromagnet 139 is detachably installed on the inner wall of the L-shaped bonding plate 138. A power supply 1310 is linearly connected to the outer surface of the L-shaped electromagnet 139 and fixedly installed on one side surface of the L-shaped bonding plate 138.

[0030] During operation, as the raw material 14 moves inside the four-column hydraulic cutting machine 11, the four-column hydraulic rod 111 presses down on the lower pressure table 112, causing the surface of the connecting extrusion plate 114 to adhere to the surface of the raw material 14, thus squeezing the raw material 14 tightly. At this time, the lower cutting plate 118 presses down further, thereby cutting and trimming the exposed raw material 14. The trimmed debris enters the chip collection groove 117 through the material drop chute 116 for collection. If some raw materials 14 are relatively thin, after lowering the lower pressure table 112, the hydraulic rod 113 pushes the connecting extrusion plate 114 a second time, thereby increasing the pressing distance of the connecting extrusion plate 114. This achieves the effect of effectively squeezing and positioning raw materials 14 of different thicknesses by changing the pressing distance of the connecting extrusion plate 114.

[0031] Working principle: The neatly stacked cut raw materials 14 are placed on the top surface of the overlapping conveyor table 12, and one side surface of the overlapping plate 134 is attached to the surface of the cut raw materials 14, so that one side surface of the cut raw materials 14 always remains neat. The motor 135 on one side surface of the overlapping plate 134 rotates the bidirectional threaded rod 136, causing the rectangular slider 137 on the outer surface of the bidirectional threaded rod 136 to move simultaneously in the same and opposite directions on the inner wall of the overlapping plate 134, under the constraint of the overlapping plate 134. While moving in the same direction, the rectangular slider 137 also moves in the same direction, pushing the rectangular... The L-shaped bonding plate 138 on the outer surface of the slider 137 is pressed and snapped onto the two corners of the cut material 14. At the same time, the L-shaped bonding plate 138 effectively limits the corner position of the material. Then, the pull rod 133 is pushed, which in turn drives the bonding overlap plate 134 to push the cut material 14 to move on the surface of the overlap conveyor table 12. If it is necessary to push some small materials with a short time distance, the pull rod 133 is pulled on the inner wall of the snap-fit ​​groove 132 to change the distance between the snap-fit ​​groove 132 and the bonding overlap plate 134, so that the pushing distance of the pull rod 133 is longer, and the cut material 14 can be pushed further.

[0032] While the raw material 14 moves inside the four-column hydraulic cutting machine 11, the four-column hydraulic rod 111 presses down on the lower pressure table 112, causing the surface of the connecting extrusion plate 114 to adhere to the surface of the raw material 14, thus squeezing the raw material 14 tightly. At this time, the lower cutting plate 118 presses down further, thereby cutting and trimming the exposed raw material 14. The debris cut off by trimming will enter the debris collection groove 117 through the material drop chute 116 for collection. If some raw materials 14 are relatively thin, after lowering the lower pressure table 112, the hydraulic rod 113 pushes the connecting extrusion plate 114 a second time, thereby increasing the pressing distance of the connecting extrusion plate 114. This achieves the effect of effectively squeezing and positioning raw materials 14 of different thicknesses by changing the pressing distance of the connecting extrusion plate 114.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
