Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for shearing machines, specifically a shearing machine guardrail and a shearing machine. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another to shear sheet metal. It utilizes a moving upper blade and a fixed lower blade, with a suitable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. During shearing, edge chipping can occur, posing a safety hazard to the equipment user and workers on the processing site. CN207930058U discloses a shearing machine guardrail and shearing machine, in which the guardrail strips are fixed to the shearing nozzle of the shearing machine via connectors, providing a certain degree of protection. However, when adjusting the blade holder or blade support, the presence of the guardrail requires disassembly and reassembly. Furthermore, during shearing, the guardrail obstructs the view, requiring the user to bend over to observe whether the shear line on the sheet metal surface is aligned with the blade support, which is somewhat inconvenient. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model provides a shearing machine guardrail and a shearing machine, which allows for adjustment of the guardrail's position, facilitating the debugging of the shearing machine, while also preventing the guardrail from obstructing the shearing area and simplifying processing.

[0004] To achieve the above objectives, the present invention provides a shearing machine guardrail, comprising a rotating seat and a fixed seat, each in a pair. A guide rail box is rotatably connected to the center of the rotating seat. A cavity is provided inside the guide rail box, and a fixed seat is fixedly connected to the center of the cavity. Guide rods are fixedly connected to both sides of the fixed seat and the inner wall of the cavity. Moving blocks are slidably connected to the surfaces of the guide rods. A support spring is provided at the bottom of each moving block. A connecting plate is fixedly connected to one side of each moving block. A guardrail is provided between the two guide rail boxes, fixed to one side of the connecting plate. The fixed seats are located on one side of the guardrail and are symmetrically arranged. A pressure plate is fixedly connected to the surface of the fixed seat via a connecting frame. A support plate is fixedly connected to one side of the guardrail. A limit adjustment component is provided between the fixed seat and the guide rail box to restrict the rotation of the guide rail box.

[0005] Preferably, the surface of the guardrail is provided with grid holes, the grid hole array is distributed on the surface of the guardrail, and the guardrail is fixed to one side of the connecting plate by bolts.

[0006] Preferably, the limiting adjustment assembly includes a first connecting block, a second connecting block, a third connecting block, and a connecting shaft. The first connecting block and the second connecting block are fixedly connected to the fixed base and form an integral structure. The third connecting block is fixedly connected to the top of the guide rail box and forms an integral structure. The third connecting block is disposed between the first connecting block and the second connecting block and connected by the connecting shaft. One end of the connecting shaft is fixedly connected to a limiting block, and the other end of the connecting shaft is fixedly connected to a fixed block. The surface of the connecting shaft is provided with a toothed groove extending along the axial direction of the connecting shaft. A rotating sleeve is rotatably connected inside the second connecting block, and the rotating sleeve engages with the toothed groove. The inner walls of the first connecting block and the third connecting block are provided with racks adapted to the toothed groove. The length of the rack inside the first connecting block is half the width of the first connecting block. A return spring is provided between one side of the limiting block and the first connecting block.

[0007] Preferably, the length of the toothed segment is greater than the sum of the widths of connecting block two and connecting block three, and the length of the toothed segment is less than the sum of the widths of connecting block one, connecting block two, and connecting block three.

[0008] Preferably, the surface of the movable block is provided with a rubber layer, the surface of the rubber layer is in contact with the inner wall of the cavity, and the surface of the guide rail box is provided with an elongated hole adapted to the connecting plate.

[0009] A shearing machine includes the aforementioned shearing machine guardrail, wherein the rotating seat is fixed on the side of the machine frame near the operating table, and the fixed seat is fixed on the side of the blade holder. When the blade holder moves down, the guardrail moves down synchronously through the fixed seat.

[0010] Preferably, the two rotating seats are arranged at the same horizontal height, the two fixed seats are arranged at the same horizontal height, the bottom of the pressure plate is in contact with the top of the support plate, and the horizontal plane at the bottom of the guardrail is lower than the horizontal plane at the cutting edge of the shearing machine.

[0011] The present invention adopts the above-mentioned technical solution, and its beneficial effects include: This type of shearing machine guardrail, by moving downwards through the pressure plate and support plate during the downward movement of the blade holder, avoids edge chipping during processing that could injure the operator. Because the guardrail is in a higher position before shearing, it avoids obstructing the shearing area and facilitates positioning before shearing. The connection between the guide rail box and the fixed seat using a limit adjustment component ensures that the guide rail box can be rotated during shearing machine debugging, facilitating the adjustment of the blade holder and blade support position without disassembling the guardrail, thus improving work efficiency.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a shearing machine guardrail, including a rotating seat 1 and a fixed seat 2. Each rotating seat 1 and fixed seat 2 is provided in pairs. A guide rail box 3 is rotatably connected to the center of the rotating seat 1. The guide rail box 3 is vertically arranged and has a cavity 4 inside. A fixed seat 5 is fixedly connected to the center of the cavity 4. Guide rods 6 are fixedly connected to both sides of the fixed seat 5 and the inner wall of the cavity 4. A moving block 7 is slidably connected to the surface of the guide rod 6. A support spring 8 is provided at the bottom of the moving block 7. A connecting plate 9 is fixedly connected to one side of the moving block 7. The two guide rail boxes 3... A guardrail 10 is provided between the plates, and the guardrail 10 is fixed to one side of the connecting plate 9. The fixing seat 2 is set on one side of the guardrail 10 and is symmetrically arranged. The surface of the fixing seat 2 is fixedly connected to the pressure plate 12 through the connecting frame 11. The support plate 13 is fixedly connected to one side of the guardrail 10. When the pressure plate 12 moves downward, it applies pressure to the support plate 13, which drives the guardrail 10 to move downward. The support spring 8 is compressed. When the pressure plate 12 moves upward, the guardrail 10 is reset under the action of the support spring 8. This realizes protection by moving the guardrail downward during shearing and avoids the guardrail from blocking the plate when positioning it.

[0020] A limiting adjustment assembly is provided between the fixed base 2 and the guide rail box 3 to restrict the rotation of the guide rail box 3. The limiting adjustment assembly includes a connecting block 14, a connecting block 25, a connecting block 36, and a connecting shaft 17. The connecting block 14 and the connecting block 25 are fixedly connected to the fixed base 2 and are an integral structure. The connecting block 36 is fixedly connected to the top of the guide rail box 3 and is an integral structure. The connecting block 36 is located between the connecting block 14 and the connecting block 25 and is connected by the connecting shaft 17. One end of the connecting shaft 17 is fixedly connected to a limiting block 18, and the other end of the connecting shaft 17 is fixedly connected to a fixing block 19. The surface of the connecting shaft 17 is provided with a toothed groove section 20 extending along the axial direction of the connecting shaft 17. A rotating sleeve 21 is rotatably connected inside the connecting block 25. The rotating sleeve 21 is engaged with the toothed groove section 20. The structure of the rotating sleeve 21 is as follows: Figure 5 As shown, a limit ring is provided on the surface to achieve a rotatable connection with connecting block 2 15. The inner walls of connecting block 1 14 and connecting block 3 16 are provided with racks adapted to the toothed section 20. The length of the rack in connecting block 1 14 is half the width of connecting block 1 14. A return spring 22 is provided between one side of the limit block 18 and connecting block 1 14. The length of the toothed section 20 is greater than the sum of the widths of connecting block 2 15 and connecting block 3 16, and the length of the toothed section 20 is less than the widths of connecting block 1 14 and connecting block 2 15. When the sum of the widths of the connecting block 16 and the guide rail box 3 needs to be adjusted, pressure is applied to one side of the limiting block 18, the return spring 22 is compressed, the connecting shaft 17 moves along its axial direction, and the toothed section 20 separates from the connecting block 14. At this time, the guide rail box 3 can be rotated. When the guide rail box 3 rotates to the required position, the limiting block 18 is released, and the connecting shaft 17 is reset under the action of the return spring 22. One side of the toothed section 20 engages with the rack in the connecting block 14, thereby fixing the rotation angle of the guide rail box 3.

[0021] The surface of the guardrail 10 is provided with grid holes, and the grid hole array is distributed on the surface of the guardrail 10. The guardrail 10 is fixed to one side of the connecting plate 9 by bolts, and the bolt fixing makes it easy to disassemble.

[0022] The surface of the movable block 7 is provided with a rubber layer, and the surface of the rubber layer is in contact with the inner wall of the cavity 4. The rubber layer provides a certain damping effect on the movable block 7, reducing the bouncing of the movable block 7. The surface of the guide rail box 3 is provided with elongated holes that are compatible with the connecting plate 9.

[0023] A shearing machine includes the aforementioned shearing machine guardrail. A rotating seat 1 is fixed on the side of the machine frame near the operating table, and a fixed seat 2 is fixed on the side of the blade holder. The fixed seat 2 is specifically installed in the fixing hole of the blade and is located on one side of the blade clamp. During shearing, the guide rail box 3 is vertically set. When the blade holder moves down, the guardrail 10 moves down synchronously through the fixed seat 2. The surfaces of the rotating seat 1 and the fixed seat 2 are provided with mounting holes and are fixed with bolts. The original bolts of the blade clamp are not long enough when the thickness of the fixed seat 2 is added, so the fixed seat 2 is fixed with extended bolts.

[0024] The two rotating seats 1 are set at the same horizontal height, the two fixed seats 2 are set at the same horizontal height, the bottom of the pressure plate 12 contacts the top of the support plate 13, and the bottom of the guardrail 10 is at a lower horizontal plane than the cutting edge of the shearing machine blade, ensuring that the guardrail 10 reaches the protective position before shearing, thus completing the protection and improving safety.
