Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0018] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a shearing device for scrap steel recycling, including workbench 1, the side of the workbench 1 is correspondingly provided with side plate 11 and support plate 12, the top of the support plate 12 is provided with lifting hydraulic cylinder 14, the top of the lifting hydraulic cylinder 14 is connected with top plate 15, the middle part of the top plate 15 is provided with movable slot 19, movable seat 18 is movably clamped in the movable slot 19, two movable seats 18 are correspondingly screwed on bidirectional screw rod 2, the end of the bidirectional screw rod 2 is connected with motor, the movable seat 18 is connected with fixed seat 22 by positioning bolt 21, positioning lug 24 is detachably installed in the positioning groove 23 of the side of the fixed seat 22 by connecting mechanism, the bottom of the positioning lug 24 is installed with shearing tool 25, the middle part of the top plate 15 is provided with pressing mechanism, the inner side of the positioning block 35 is connected with anti-deviation plate 37 by limiting push rod 36.

[0019] The height of the top plate 15 can be adjusted by the lifting hydraulic cylinder 14, so as to adjust the working height of the shearing tool 25, to adapt to the shearing demand of scrap steel of different thicknesses; the bidirectional screw rod 2 is driven by the motor to synchronously move the two movable seats 18 in the movable slot 19 towards or away from each other, to realize accurate adjustment of the horizontal distance between the two shearing tools 25. The structure solves the problem that the distance between the tools of the traditional shearing device is fixed and cannot adapt to scrap steel of different widths, can flexibly adjust the shearing position according to the size of the material, realizes shearing of multiple sections of scrap steel at a time, and significantly improves the processing efficiency; the cooperation design of the positioning groove 23 and the connecting mechanism provides a structural basis for subsequent tool quick replacement; the setting of the pressing mechanism and the anti-deviation plate 37 provides hardware support for material fixation and deviation prevention.

[0020] In the above scheme, the bottom of the workbench 1 is provided with castor 13. The castor 13 is a self-locking type castor, and the castor 13 is provided to make the device movable, to facilitate adjustment of the equipment position according to the production layout, especially suitable for multi-station collaborative operation scene, to improve the convenience of equipment use.

[0021] In the above scheme, the support plate 12 is provided with a guide rod 16, and the guide rod 16 is movably inserted into the guide hole of the top plate 15. The guide rod 16 and the guide hole constitute a linear guide structure. When the lifting hydraulic cylinder 14 drives the top plate 15 to lift, the guide rod 16 can limit the lateral shaking of the top plate 15, ensure the stability of the vertical movement of the shearing tool 25, and avoid the deviation of the shearing precision caused by the shaking.

[0022] In the above scheme, the edge below the top plate 15 is provided with a protective cover 17. The protective cover 17 covers the outer side area of the shearing tool 25, can effectively block the flying metal scraps and sparks in the shearing process, reduces the safety threat to the operator, avoids the influence of the scrap accumulation on the equipment operation, and improves the safety and reliability of the device.

[0023] In the above scheme, the connecting mechanism includes a limiting plate 26 arranged outside the fixed seat 22. The outer side of the limiting plate 26 is connected with a pull plate 28 through a spring 27. The inner side of the pull plate 28 is provided with a limiting rod 29. The movable end of the limiting rod 29 passes through the limiting plate 26 and is correspondingly inserted into the limiting hole 3 outside the positioning protrusion 24. When the shearing tool 25 needs to be replaced, the pull plate 28 is pulled outward, the spring 27 is compressed, the limiting rod 29 is separated from the limiting hole 3, and the positioning protrusion 24 and the tool can be quickly removed. When installing, the positioning protrusion 24 is only inserted into the positioning groove 23, the spring 27 is reset to push the limiting rod 29 to be inserted into the limiting hole 3 to complete the locking. The quick-release connecting mechanism can be operated without tools. Compared with the traditional bolt fastening mode, the tool replacement time is shortened to within 30 seconds, and the production change efficiency is significantly improved.

[0024] In the above scheme, the pressing mechanism includes a sleeve 31. The bottom of the sleeve 31 is connected with a buffer rod 32 through a tension spring. The bottom of the buffer rod 32 is connected with a base 33. The bottom of the base 33 is provided with a roller 34. The pressing mechanism makes the roller 34 always adhere to the surface of the scrap steel through the elastic force of the tension spring, continuously applies pressure during the shearing process, and prevents the material from jumping due to the shearing force. The roller 34 can roll with the movement of the material, avoiding the surface scratch of the material caused by the traditional rigid pressing. The spacing of the anti-deviation plate 37 can be adjusted by cooperating with the limiting push rod 36, so as to form three-sided limiting and top pressing of the scrap steel of different widths, and ensure the accurate position of the material during shearing.

[0025] In the above scheme, the end of the workbench 1 is connected with an inclined guide plate 38, the end of the guide plate 38 is out of the discharging port 39 on the side plate 11, and the guide plate 38 is provided with a guide roller shaft 4. The inclined guide plate 38 guides the sheared scrap steel to slide to the discharging port 39 of the side plate 11 by gravity, and the guide roller shaft 4 reduces the friction between the material and the guide plate 38, so that the discharging process is smoother, the efficiency loss and safety risk caused by manual handling are avoided, and it is especially suitable for continuous production scenes, and the automatic connection of the shearing-discharging process can be realized.

[0026] Working principle:

[0027] The scrap steel recycling shearing device, when the lifting hydraulic cylinder 14 is powered on, the piston rod extends or retracts, pushes the top plate 15 to move up and down along the guide rod 16, so as to adjust the vertical height of the shearing cutter 25. The cooperation of the guide rod 16 and the guide hole ensures the stable lifting of the top plate 15. This process can accurately adjust the working height of the cutter according to the stacking height of the scrap steel or the shearing thickness requirement;

[0028] When the motor (not shown in the figure) is connected to the power supply, it drives the bidirectional screw rod 2 to rotate. Since the two moving seats 18 are respectively screwed on the positive and negative threaded segments of the bidirectional screw rod 2, the rotation of the bidirectional screw rod 2 will make the moving seats 18 move synchronously towards or away from each other in the movable groove 19, so as to adapt to the shearing requirements of scrap steel of different widths and achieve the effect of simultaneous shearing processing;

[0029] When the scrap steel is placed on the workbench 1 and pushed to the shearing area, it first contacts the anti-deviation plate 37. The inner distance of the anti-deviation plate 37 is adjusted by the limiting push rod 36, so that it fits the edges of the scrap steel on both sides to form horizontal limiting; at the same time, the rollers 34 of the pressing mechanism are pressed tightly on the upper surface of the scrap steel under the action of the tension spring, and the elastic buffer action of the tension spring can adapt to materials of different thicknesses, avoiding surface damage caused by rigid contact. When the top plate 15 is lowered under the drive of the lifting hydraulic cylinder 14, the shearing cutter 25 moves downward synchronously with the positioning lug 24 to shear the fixed scrap steel, and the rollers 34 roll on the surface of the material to ensure that the pressing force is evenly distributed;

[0030] When the cutter needs to be replaced, pull out the pull plate 28 to overcome the elastic force of the spring 27, and the limiting rod 29 is withdrawn from the limiting hole 3 of the positioning lug 24, so that the positioning lug 24 together with the cutter can be taken out from the positioning groove 23 of the fixed seat 22; when installing a new cutter, insert the positioning lug 24 into the positioning groove 23, and the spring 27 resets to push the limiting rod 29 to automatically enter the new limiting hole 3, so that the replacement can be completed without tools;

[0031] During shearing process, the protective cover 17 blocks the splashing debris and sparks, protecting the safety of the operator; after shearing is completed, the top plate 15 rises and resets, the scrap steel is manually pushed, and the scrap steel slides along the inclined guide plate 38 under the action of gravity, the guide roller shaft 4 reduces the friction resistance, so that the scrap steel quickly falls into the collection area through the discharge port 39 of the side plate 11.

[0032] Through the above working process, the device can realize efficient operation of the whole process from material positioning, spacing adjustment, shearing processing to safe unloading, and significantly improve the automation level and production efficiency of scrap steel recycling and processing.

[0033] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
