Description

Technical Field

[0001] This utility model relates to the field of scrap steel recycling technology, and in particular to a large scrap steel shearing machine. Background Technology

[0002] Scrapped cars, large equipment, ships and other items generate a large amount of scrap steel when they are scrapped. This scrap steel can be recycled and reused. However, the shape, size and thickness of the scrap steel are different, which means that it takes up a lot of space when stored. It is necessary to use a shearing machine to cut the large pieces of scrap steel into smaller pieces, which can reduce the space occupied by the scrap steel and facilitate subsequent remelting and accelerate the melting speed of the scrap steel.

[0003] When a shearing machine is working, a conveyor belt transports large pieces of scrap steel to the shearing position on the shearing table. A hydraulic telescopic cylinder pushes a pressure plate hinged to the table downwards to press down on the scrap steel. Another hydraulic telescopic cylinder pushes a shearing blade hinged to the table downwards to squeeze the scrap steel. This causes the scrap steel to break when subjected to extreme shearing force at the point between the shearing blade and the table surface, thus shearing the scrap steel. However, in this technology, because the hinge points of the pressure plate and the shearing blade are arranged side-by-side, and both exert lateral thrust on the scrap steel twice in the same horizontal direction, the fixed scrap steel is prone to displacement, leading to jamming problems during shearing. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a large scrap steel shearing machine to solve the problem of scrap steel easily shifting position during shearing, which leads to material jamming.

[0005] To achieve the above objectives, this utility model provides a large scrap steel shearing machine, including a gantry frame and horizontal connecting rods at both ends that are slidably connected to two vertical slots located inside the gantry frame.

[0006] A drive mechanism used to raise and lower the cross link.

[0007] Two guide grooves are set on the table surface and a push block is slidably set in the guide groove.

[0008] A telescopic arm hinged between the push block and the cross link.

[0009] A floating clamping part is provided at the bottom of the cross link. The floating clamping part includes at least two guide sleeves. The guide sleeves are provided with sliding grooves, and sliding blocks are slidably provided in the sliding grooves.

[0010] A first clamp hinged between the cross link and the slide, and a second clamp hinged between two adjacent slides.

[0011] During operation, the drive unit drives the horizontal connecting rod to move downward, and the two telescopic arms push the two push blocks closer to each other to achieve the centered positioning of the scrap steel. When the pressure continues to be applied, the floating clamping part adaptively clamps scrap steel of different thicknesses.

[0012] Preferably, the gantry frame is fixedly mounted on the platform, and the gantry frame and the shearing blade are distributed sequentially along the scrap steel feeding direction.

[0013] Preferably, the driving component can be a telescopic cylinder, with its output end fixed on the horizontal connecting rod and its other end fixed on the gantry frame.

[0014] Preferably, the driving component may be a screw threaded onto the gantry and a servo motor fixed to the gantry, with the output end of the servo motor fixed to the top of the screw and the bottom end of the screw rotatably mounted on the cross link.

[0015] Preferably, the moving direction of the pusher block is perpendicular to the scrap steel feeding direction in the horizontal plane, and the initial position of the pusher block is located in the guide groove near the connection between the gantry and the table.

[0016] Preferably, the vertical cross-sectional shape inside the guide groove is convex, and the vertical cross-section of the push block is I-shaped.

[0017] Preferably, the first clamp and the second clamp have the same structure, and the first clamp includes a pressure block and two connecting arms hinged to the pressure block. The free ends of the two connecting arms are respectively hinged to the bottom of the cross link and the slide block, and a limiting frame is fixedly provided on the top of the pressure block.

[0018] Preferably, the limiting frame is in the shape of an inverted U, and the limiting frame is located between the two connecting arms.

[0019] The beneficial effects of this utility model are:

[0020] This invention utilizes a combination of a floating clamping part, a horizontal connecting rod, a telescopic arm, and push blocks. During the first half of the downward stroke of the floating clamping part, the two telescopic arms push the two push blocks closer together to laterally center and limit the scrap steel on the table. Then, during the second half of the downward stroke of the floating clamping part, scrap steel of different thicknesses can be clamped simultaneously. At the same time, the telescopic arms retract and accumulate elastic force, increasing the lateral constraint effect on the scrap steel, improving the positioning and fixing effect of the scrap steel, and preventing the scrap steel from shifting position during shearing, which would affect the normal operation of the shearing machine.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0030] likeFigures 1 to 4 As shown, a large scrap steel shearing machine includes a gantry frame 1 and a horizontal connecting rod 3 whose two ends are slidably connected to two vertical slots 2 located in the gantry frame 1, so that the vertical slots 2 constrain the degree of freedom of the horizontal connecting rod 3, so that the horizontal connecting rod 3 can only perform linear lifting and lowering motion, and improve the stability of the lifting and lowering motion of the horizontal connecting rod 3.

[0031] Drive component 8 used to raise and lower the cross link 3.

[0032] Two guide grooves 5 are respectively set on the table surface and a push block 6 is slidably set in the guide grooves 5.

[0033] The telescopic arm 7 is hinged between the push block 6 and the cross link 3. The telescopic arm 7 includes a sleeve hinged to one end of the cross link 3 and an insert rod inserted into the free end of the sleeve. A compression spring is sleeved inside the sleeve. The two ends of the compression spring abut against the end face of the insert rod away from the push block and the end face of the sleeve rod away from the insert rod, respectively. One end of the insert rod is hinged to the push block 6. The length reserved in the sleeve rod for the retraction of the insert rod is greater than the maximum descent height of the cross link 3. This design allows multiple scrap steel pieces to be pushed side by side between the two push blocks 6, so that the scrap steel is centered in the shearing position. When multiple scrap steel pieces are close together, the push block 6 can stop moving. Then, as the cross link 3 continues to descend, the telescopic arm 7 shortens and increases the squeezing force of the push block 6 on the scrap steel, improving the stability and firmness of the lateral limit of the scrap steel.

[0034] A floating clamping part 4 is provided at the bottom of the cross link 3. The floating clamping part 4 includes at least two guide sleeves 41. A sliding groove 42 is provided in the guide sleeve 41, and a sliding seat 45 is slidably provided in the sliding groove 42.

[0035] The first clamp 43, hinged between the cross link 3 and the slide 45, and the second clamp 44, hinged between two adjacent slides 45, are designed such that when one of the first clamps 43 contacts the thickest scrap steel, it pushes the slide 45 connected to it away, thereby reducing the distance between the two adjacent slides 45 and the distance between the slide 45 and the hinge point between the other first clamp 43 and the cross link 3. When one of the second clamps 44 or the other first clamp 43 contacts the second thickest scrap steel, it causes the remaining slides 45 to... The distance between two adjacent slides 45 is reduced, as is the distance between the slide 45 and the hinge point of another first clamp 43 and the horizontal connecting rod 3, or the distance between two adjacent slides 45 is reduced. This process is repeated until the other first clamp 43 and at least two second clamps 44 are all pressed and fixed with a corresponding scrap steel, so as to press and fix multiple scrap steels of different thicknesses at the same time. In addition, the push block 6 limits and blocks in the lateral direction, which improves the positioning and fixing effect of the scrap steel and avoids the problem of the shearing machine jamming due to the position displacement of the scrap steel.

[0036] During operation, the drive component 8 drives the horizontal connecting rod 3 to move downward, and the two telescopic arms 7 push the two push blocks 6 to move closer to each other, so as to center and position the scrap steel. When pressing down, the floating clamping part 4 adaptively clamps scrap steel of different thicknesses.

[0037] like Figure 1 and Figure 2 As shown, the gantry frame 1 is fixed on the table, and the gantry frame 1 and the shearing blade are distributed sequentially along the scrap steel feeding direction. This design allows the shearing blade and the vertical surface of the table to be staggered in the scrap steel feeding direction, so as to concentrate the shearing force and improve the smoothness of scrap steel shearing.

[0038] like Figure 1 and Figure 2 As shown, the drive component 8 can be a telescopic cylinder, with the output end fixed on the horizontal connecting rod 3 and the other end fixed on the gantry frame 1. This allows the horizontal connecting rod 3 to rise and fall quickly, and the upper limit of the compression is greater, making it suitable for short-distance lifting and lowering of the horizontal connecting rod 3.

[0039] like Figure 1 and Figure 2 As shown, the driving component 8 can be a screw threaded onto the gantry 1 and a servo motor fixed onto the gantry 1. The output end of the servo motor is fixed to the top of the screw, and the bottom end of the screw is rotatably mounted on the horizontal connecting rod 3, so that the horizontal connecting rod 3 can be raised and lowered at a uniform speed and stably, which is suitable for long-distance lifting scenarios of the horizontal connecting rod 3.

[0040] like Figures 1 to 3 As shown, the moving direction of the pusher block 6 is perpendicular to the scrap steel feeding direction in the horizontal plane, and the initial position of the pusher block 6 is located in the guide groove 5 near the connection between the gantry frame 1 and the table.

[0041] The vertical cross-section of the guide groove 5 is convex, and the vertical cross-section of the push block 6 is I-shaped. This design allows the guide groove 5 to constrain the degree of freedom of the push block 6, so that the two push blocks 6 can only make linear movements that move closer or further away from each other, and improves the stability of the push block 6 when it moves.

[0042] like Figure 3 and Figure 4 As shown, the first clamp 43 and the second clamp 44 have the same structure. The first clamp 43 includes a pressure block 431 and two connecting arms 432 hinged to the pressure block 431. The free ends of the two connecting arms 432 are respectively hinged to the bottom of the horizontal connecting rod 3 and the slide block 45. A limiting frame 433 is fixedly provided on the top of the pressure block 431.

[0043] The limiting frame 433 is in the shape of an inverted U and is located between two connecting arms 432. With this design, when several pressure blocks 431 successively contact scrap steel of different thicknesses from large to small, the included angle between the two connecting arms 432 on the corresponding pressure block 431 gradually decreases. This allows the height of the pressure blocks 431 at different positions to gradually increase, so that when multiple scrap steels of different thicknesses are clamped at the same time, multiple scrap steels of different thicknesses can be clamped adaptively.

[0044] Working principle: During operation, the drive component 8 drives the horizontal connecting rod 3 to descend, and simultaneously pushes the two push blocks 6 closer together through the two telescopic arms 7, pushing multiple scrap steel pieces side by side between them, so that the scrap steel pieces are centered in the shearing position. When multiple scrap steel pieces are close together, the push blocks 6 can stop moving. Then, as the horizontal connecting rod 3 continues to descend, the telescopic arms 7 shorten and increase the squeezing force of the push blocks 6 on the scrap steel, improving the stability and firmness of the lateral limit of the scrap steel. Then, the drive component 8 continues to drive the horizontal connecting rod 3 to descend. When one of the first clamps 43 abuts against the scrap steel with the maximum thickness, it pushes the slide block 45 connected to it away, thereby increasing the distance between the two adjacent slide blocks 45 and the slide block 4. The distance between the hinge point of the second clamp 44 and the other first clamp 43 and the horizontal connecting rod 3 is reduced. When one of the second clamps 44 or the other first clamp 43 comes into contact with the second thickest scrap steel, the distance between two adjacent slides 45 in the remaining slides 45 is reduced and the distance between the slide 45 and the hinge point of the other first clamp 43 and the horizontal connecting rod 3 is reduced, or the distance between two adjacent slides 45 is reduced. This process is repeated until the other first clamp 43 and at least two second clamps 44 are pressed and fixed with a corresponding scrap steel, so as to press and fix multiple scrap steels of different thicknesses at the same time. With the push block 6 limiting and blocking in the lateral direction, the positioning and fixing effect of the scrap steel is improved.
