Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a protective device for a shearing machine. Background Technology

[0002] A shearing machine is a common mechanical device that uses upper and lower blades to shear metal sheets. It is widely used in industries such as metallurgy, automobiles, shipbuilding, and building materials. Because the shearing force of the blades is enormous during operation, and the feeding and discharging processes of the sheets pose certain risks, installing protective devices in the shearing machine's feed inlet area is an important measure to ensure operator safety and prevent workplace accidents.

[0003] Currently, existing shearing machine feed inlet protection devices typically use fixed-height guardrails or protective plates. While this structure can isolate dangerous areas to some extent, it has significant limitations. In actual production, the size, thickness, and number of stacked layers of the processed boards vary, resulting in significant differences in the stacking height of the boards. Fixed-height guardrails cannot adapt to this variation: when the guardrail is too low, although it provides strong safety, it affects the feeding of thicker boards or those with higher stacking heights, and also affects the operator's observation of board positioning and the feeding process, potentially leading to operational errors due to obstructed vision; when the guardrail is too high, although it can reduce the impact on board feeding, the large gap between the bottom of the guardrail and the feed table also increases operational safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a protective device for a shearing machine, which can adjust the height of the protective railing according to processing requirements, thereby expanding the applicability of the equipment.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a shearing machine protective device, including a shearing machine body, a feed inlet and a feed table are provided on one side of the shearing machine body, the shearing machine body is provided with a protective railing group located at the feed inlet, the protective railing group includes a first protective railing fixedly installed on the shearing machine body, and the first protective railing is connected to a second protective railing through a fastening component.

[0006] By adopting the above technical solution, the first guardrail and the second guardrail are connected by the first fastener, so that the second guardrail can be raised and lowered to adjust the overall height of the guardrail group according to processing needs, which can effectively expand the application range of the equipment and improve the accuracy and reliability of safety protection.

[0007] A further feature of this invention is that: connecting rods are fixed on both sides of the first guardrail, and adjusting rods are fixed on both sides of the second guardrail; the connecting rods have cavities inside, and through holes communicating with the cavities are provided outside the connecting rods; the adjusting rods pass through the through holes and the cavities and are then fixed by fastening components.

[0008] By adopting the above technical solution, the adjusting rod is inserted into the connecting rod through the through hole and then fixed by the fastening assembly, so as to realize the rapid adjustment of the adjusting rod.

[0009] A further feature of this invention is that the fastening assembly includes a first fastener and a second fastener respectively located on both sides of the adjusting rod within the cavity. The first fastener is fixedly disposed within the cavity, and the second fastener is movably disposed within the cavity. The connecting rod is connected to an adjusting member for pressing or releasing the second fastener.

[0010] By adopting the above technical solution, when the adjusting component pushes and presses the second fastener, the second fastener moves towards the adjusting rod, thereby pressing the adjusting rod together with the first and second fasteners, achieving relative fixation of the first and second guardrails; when adjusting the height of the second guardrail, the adjusting component loosens the second fastener, allowing the second fastener to move within the cavity, thereby loosening the adjusting rod. At this time, the adjusting rod and the second guardrail can be raised and lowered to adjust the height of the second guardrail, making the adjustment more efficient.

[0011] A further feature of this invention is that the connecting rod has an external thread at one end near the second fastener, and the adjusting member is configured as an internal thread sleeve threaded to the external thread.

[0012] By adopting the above technical solution, by rotating the internal threaded sleeve, the internal threaded sleeve moves closer to the adjusting rod, pushing the second fastener to press the adjusting rod; by rotating the internal threaded sleeve in the opposite direction, the internal threaded sleeve moves away from the adjusting rod, and at the same time loosens the second fastener, so that the second fastener is in a movable state in the cavity and no longer presses the adjusting rod. At this time, the adjusting rod can be raised or lowered to adjust the height.

[0013] A further feature of this invention is that the first fastener and the second fastener have an arc-shaped fastening groove on their opposite sides that presses against the outer wall of the adjusting rod.

[0014] By adopting the above technical solution, the arc-shaped fastening groove can effectively increase the contact area between the fastener and the adjusting rod, so that the first fastener and the second fastener are pressed against both sides of the adjusting rod through the arc-shaped fastening groove.

[0015] A further feature of this invention is that: mirror sliding limit plates are installed on both sides of the bottom of the second guardrail.

[0016] By adopting the above technical solution, the limiting plates on both sides form parallel guide channels. When feeding the material into the main body of the shearing machine, the limiting plates are located on both sides of the plate, which can accurately control the feeding width of the plate and ensure that the plate remains parallel to the cutting edge during the feeding process, thereby improving the product processing quality. Moreover, it eliminates the need for the operator to repeatedly straighten and adjust the plate by hand, further reducing safety hazards.

[0017] A further feature of this invention is that: an adjustment plate is fixed at the bottom of the second guardrail, the adjustment plate has an adjustment groove, an adjustment screw is rotatably connected in the adjustment groove, the two ends of the adjustment screw are provided with reverse threads and are threadedly connected to a moving block that slides in the adjustment groove, and the limiting plate is fixed to the bottom of the moving block.

[0018] By adopting the above technical solution, the moving blocks on both sides are driven to slide closer or further away in the adjustment groove by rotating the adjusting screw, thereby adjusting the distance between the limiting plates on both sides according to the width of the plate, thus expanding the applicable range of the limiting plates.

[0019] A further feature of this invention is that a handwheel is fixed to one end of the adjusting screw extending from the adjusting plate.

[0020] By adopting the above technical solution, the distance between the two limit plates can be easily adjusted by rotating the screw through the handwheel.

[0021] A further feature of this invention is that accordion baffles are provided between the moving block and the inner wall of the adjusting groove, and between the moving blocks on both sides.

[0022] By adopting the above technical solution, when the two moving blocks move, they can simultaneously pull the bellows baffle to protect the adjusting screw inside the adjusting groove.

[0023] A further feature of this invention is that the limiting plates on both sides are provided with a groove on one side opposite to the groove, and multiple guide rollers are rotatably connected in the groove.

[0024] By adopting the above technical solution, the friction between the feeding plate and the limiting plate can be reduced, the wear of the plate can be reduced, the feeding operation can be made easier, and the labor intensity of the operator can be reduced.

[0025] The beneficial effects of this utility model are:

[0026] 1. The first guardrail and the second guardrail are connected by the first fastener, so that the second guardrail can be raised and lowered according to the processing needs to adjust the overall height of the guardrail group, which can effectively expand the application range of the equipment and improve the accuracy and reliability of safety protection;

[0027] 2. By setting limit plates on both sides, parallel guide channels are formed. When feeding the material into the main body of the shearing machine, the limit plates are located on both sides of the board, which can accurately control the feeding width of the board and ensure that the board remains parallel to the blade during the feeding process, thus improving the product processing quality. Moreover, the operator does not need to repeatedly straighten and adjust the board by hand, further reducing safety hazards. Attached Figure Description

[0036] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] Example 1: A protective device for a shearing machine, such as... Figure 1-2 As shown, the shearing machine includes a main body 1, which adopts a conventional structure in the prior art, including a frame, a blade holder and shearing system, a transmission system, and a material pressing system. A feed inlet 2 and a feed table 3 are provided on one side of the main body 1. The main body 1 is equipped with a protective railing assembly located at the feed inlet 2. The protective railing assembly includes a first protective railing 4 fixedly installed on the main body 1, and a second protective railing 5 connected to the first protective railing 4 via a fastening assembly 6. The first protective railing 4 and the second protective railing 5 are connected by a first fastener 61, allowing the second protective railing 5 to be raised or lowered according to processing needs to adjust the overall height of the protective railing assembly. This effectively expands the applicability of the equipment and improves the accuracy and reliability of safety protection.

[0038] Furthermore, multiple telescopic rods can be added side by side between the bottom of the first guardrail 4 and the top of the second guardrail 5. The overall length of the telescopic rods changes with the height of the second guardrail 5, which can further improve the reliability of the protection.

[0039] like Figure 2-5 As shown, connecting rods 7 are fixed on both sides of the first guardrail 4, and adjusting rods 8 are fixed on both sides of the second guardrail 5. The connecting rods 7 have internal cavities and through holes 10 connecting to these cavities. The adjusting rods 8 pass through the through holes 10 and the cavities and are then fixed by fastening components 6. Inserting the adjusting rods 8 into the connecting rods 7 through the through holes 10 and then fixing them with the fastening components 6 allows for rapid adjustment of the adjusting rods 8.

[0040] Furthermore, the fastening assembly 6 includes a first fastener 61 and a second fastener 62 respectively located on both sides of the adjusting rod 8 within the cavity. The first fastener 61 is fixedly disposed within the cavity, while the second fastener 62 is movably disposed within the cavity. The connecting rod 7 is connected to an adjusting member 63 that tightens or loosens the second fastener 62. When the adjusting member 63 pushes the second fastener 62 to tighten it, the second fastener 62 moves closer to the adjusting rod 8, thereby pressing the adjusting rod 8 together with the first fastener 61 and the second fastener 62, achieving relative fixation of the first guardrail 4 and the second guardrail 5. When adjusting the height of the second guardrail 5, the adjusting member 63 loosens the second fastener 62, allowing the second fastener 62 to move within the cavity, thereby loosening the adjusting rod 8. At this time, the adjusting rod 8 and the second guardrail 5 can be raised and lowered to adjust the height of the second guardrail 5, making the adjustment more efficient.

[0041] Furthermore, the connecting rod 7 has an external thread 64 at the end near the second fastener 62, and the adjusting member 63 is configured as an internal threaded sleeve threaded to the external thread 64. By rotating the internal threaded sleeve, the internal threaded sleeve moves closer to the adjusting rod 8, pushing the second fastener 62 to press the adjusting rod 8; by rotating the internal threaded sleeve in the opposite direction, the internal threaded sleeve moves away from the adjusting rod 8, and at the same time loosens the second fastener 62, so that the second fastener 62 is in a movable state in the cavity and no longer presses the adjusting rod 8. At this time, the adjusting rod 8 can be raised or lowered to adjust the height.

[0042] Furthermore, the first fastener 61 and the second fastener 62 are provided with arc-shaped fastening grooves 65 on opposite sides, which press against the outer wall of the adjusting rod 8. The arc-shaped fastening grooves 65 can effectively increase the contact area between the fasteners and the adjusting rod 8, so that the first fastener 61 and the second fastener 62 are pressed against both sides of the adjusting rod 8 through the arc-shaped fastening grooves 65.

[0043] like Figure 6 As shown, the bottom sides of the second guardrail 5 are mirror-slidably fitted with limit plates 11. The limit plates 11 on both sides form parallel guide channels. When feeding material into the shearing machine body 1, the limit plates 11 are located on both sides of the plate, which can precisely control the feeding width of the plate. An adjustment plate 12 is fixed at the bottom of the second guardrail 5. The adjustment plate 12 has an adjustment groove 13. An adjustment screw 14 is rotatably connected in the adjustment groove 13. The two ends of the adjustment screw 14 are provided with reverse threads and are threaded to moving blocks 15 that slide in the adjustment groove 13. The limit plates 11 are fixed to the bottom of the moving blocks 15. A handwheel 16 is fixed to one end of the adjustment screw 14 that extends out of the adjustment plate 12. By rotating the adjustment screw 14 with the handwheel 16, the moving blocks 15 on both sides slide closer or further away in the adjustment groove 13, thereby adjusting the distance between the limit plates 11 on both sides according to the width of the plate.

[0044] Furthermore, accordion baffles are provided between the two movable blocks 15 and the inner walls of the two sides of the adjusting groove 13, and between the two movable blocks 15. The accordion baffles are foldable, and when the two movable blocks 15 move, they can simultaneously pull the accordion baffles to protect the adjusting screw 14 inside the adjusting groove 13.

[0045] Furthermore, the two limiting plates 11 are provided with grooves 17 on opposite sides, and multiple guide rollers 9 are rotatably connected in the grooves 17. The guide rollers 9 are used to reduce the friction between the feeding plate and the limiting plate 11, reduce plate wear, and improve the ease of feeding operation.
