Technical Field

[0001] The utility model relates to a shearing device, in particular to a shearing device for steel fiber processing which is applied in the field of steel fiber production and processing. Background Art

[0002] Steel fiber is made into long fibers by cutting fine steel wire, shearing cold-rolled strip, milling steel ingots or rapid condensation of molten steel. The tensile strength of steel fiber produced by cutting steel wire is much higher than that of steel fiber processed by other methods. Steel fiber is mainly used to make steel fiber concrete. Steel fiber produced by any method can play a role in strengthening concrete. In the process of producing steel fiber, the steel wire needs to be sheared.

[0003] The specification of Chinese patent CN212634144U discloses a wire shearing device, in which the rotating roller of the shearing mechanism is driven by a driving mechanism to realize rotation, with low energy consumption and high utilization rate of the eccentric wheel; when different specifications of the cutters need to be replaced for different specifications of the steel wires, the sleeve ring can be directly removed and replaced, which is convenient to operate.

[0004] However, in actual application, metal will generate high temperature and pressure under the action of force, thus forming complex physical and chemical reactions such as high temperature, high pressure and high speed, which will form hardened layer, oxide layer and other difficult-to-process substances on the metal surface. These substances will be deposited on the surface of the tool, making the tool blunt or even worn, resulting in tool sticking, causing multiple cut steel wires to stick together, bringing inconvenience to subsequent operations. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a shearing device for steel fiber processing, comprising a workbench, the upper end of the workbench is fixedly connected with an inverted U-shaped support cover, an inverted U-shaped fixing frame and two mounting plates from left to right in sequence, the lateral inner wall of the support cover is fixedly connected with two cylinders, the lower ends of the two cylinders are jointly fixedly connected with a shearing knife, a cutting groove is opened in the middle part of the upper end of the workbench, the cutting groove is located directly below the shearing knife, the inner bottom wall of the cutting groove is fixedly connected with a buffer pad, the left and right inner walls of the cutting groove are both fixedly connected with spring pieces, the upper end of the fixing frame is provided with a pulling plate, the front and rear lower ends of the pulling plate are both fixedly connected with a sliding rod, the lower end of the sliding rod movably penetrates the fixing frame, and the lower ends of the two sliding rods are jointly fixedly connected with a pressing plate, the outer ring sleeve of the sliding rod is provided with a spring, the front end of the mounting plate located at the front end is fixedly connected with a motor, the output end of the motor penetrates the mounting plate and is fixedly connected with a roller, the rear end of the roller is rotatably connected with the mounting plate located at the rear end, and the outer ring fixing sleeve of the roller is provided with an elastic foam cylinder.

[0007] In the above-mentioned shearing device for processing steel fibers, after the steel wire is sheared, it can effectively prevent the steel wire from sticking to the cutter, thereby improving the efficiency of steel fiber processing and facilitating use by workers.

[0008] As a further improvement of the present application, the spring piece is overall arched, and the cross-section of the spring piece is exactly a semicircle.

[0009] As a further improvement of the present application, limiting grooves are provided at both the front and rear ends of the support cover, limiting blocks are provided in the limiting grooves, and the corresponding ends of the two limiting blocks are fixedly connected to the front and rear ends of the shear knife respectively.

[0010] As a further improvement of the present application, the pressure plate includes an arched plate and a transverse plate, and a protruding end of the arched plate faces the support cover.

If the sheared steel wire adheres to the surface of the shearing knife, accompanied by the resetting of the cylinder, the shearing knife drives the sheared steel wire to move upward, and the steel wire is squeezed by the pressure plate. At the same time, the motor is started to drive the drum to rotate, so that the sheared steel wire moves to the right, thereby separating the sheared steel wire, effectively avoiding the sticking phenomenon during the steel wire shearing process, improving the steel fiber processing efficiency, and facilitating the use of the staff.

DETAILED DESCRIPTION

[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0024] The first implementation method:

[0025] Figure 1Shown is a shearing device for steel fiber processing, comprising a workbench 1, the upper end of the workbench 1 is fixedly connected with an inverted U-shaped support cover 2, an inverted U-shaped fixing frame 3 and two mounting plates 4 from left to right in sequence, the support cover 2 can suspend and support the cylinder 20, so as to facilitate shearing of the steel wire, the lateral inner wall of the support cover 2 is fixedly connected with two cylinders 20, and technical personnel in this field can select a suitable type of cylinder 20 according to actual needs, for example: SCD50x100-100-LB, the lower ends of the two cylinders 20 are commonly fixedly connected with a shearing knife 5, the front and rear ends of the support cover 2 are provided with a limiting groove 21, and a limiting block 22 is arranged in the limiting groove 21, and the corresponding ends of the two limiting blocks 22 are respectively fixedly connected with the front and rear ends of the shearing knife 5, and the limiting groove 21 and the limiting block 22 are used in combination to limit the shearing knife 5, forcing the shearing knife 5 to move vertically up and down.

[0026] Figure 2 It is shown that: a cutting groove 6 is opened in the middle of the upper end of the workbench 1, and a buffer pad 7 is fixedly connected to the inner bottom wall of the cutting groove 6 to protect the lower end of the shearing knife 5, effectively extending the service life of the shearing knife 5, and the left and right inner walls of the cutting groove 6 are fixedly connected with spring pieces 8. When the shearing knife 5 shears the steel wire downward, the spring pieces 8 will be slightly deformed. During the upward movement of the shearing knife 5, the spring pieces 8 scrape the two ends of the shearing knife 5 to reduce the probability of the knife sticking. The cutting groove 6 is located directly below the shearing knife 5, and the spring pieces 8 are arched as a whole. The two spring pieces 8 are distributed in a mirror-symmetrical manner with the longitudinal center line of the cutting groove 6.

[0027] Figure 3 It is shown that: a pull plate 9 is provided at the upper end of the fixed frame 3, and the front and rear lower ends of the pull plate 9 are fixedly connected with a slide rod 10, the lower end of the slide rod 10 movably passes through the fixed frame 3, and the lower ends of the two slide rods 10 are commonly fixedly connected with a pressure plate 11, and the outer ring of the slide rod 10 is provided with a spring 12. The existence of the spring 12 allows the pressure plate 11 to move up and down, so as to cope with steel wires of different sizes. At the same time, the pressure plate 11 also generates downward pressure, so that the sheared steel wire falls quickly. The two ends of the spring 12 are respectively fixedly connected to the lateral inner wall of the fixed frame 3 and the pressure plate 11. The pressure plate 11 includes an arched plate and a horizontal plate. The protruding end of the arched plate faces the support cover 2. The arched plate allows the pressure plate 11 to move upward when subjected to force.

[0028] Figure 4 It is shown that: the front end of the mounting plate 4 located at the front end is fixedly connected with a motor 13, and technical personnel in this field can select a suitable model of the motor 13 according to actual needs, for example: Y2-63M1-2-0.18KW, the output end of the motor 13 passes through the mounting plate 4 and is fixedly connected with a roller 14, the rear end of the roller 14 is rotatably connected to the mounting plate 4 located at the rear end, and the outer ring of the roller 14 is fixedly sleeved with an elastic foam tube 15, and the elastic foam tube 15 can be suitable for steel wires of different thicknesses, thereby improving the practicability of the equipment.

[0029] When in use, the existing feeder conveys the steel wire to the bottom of the shearing knife 5, and at the same time, the steel wire is at the bottom of the pressing plate 11 and the elastic foam tube 15, and the cylinder 20 is started to extend, so that the shearing knife 5 moves downward into the cutting groove 6 to cut the steel wire. If the sheared steel wire adheres to the surface of the shearing knife 5, along with the resetting of the cylinder 20, the shearing knife 5 drives the sheared steel wire to move upward, and the steel wire is squeezed by the pressing plate 11. At the same time, the motor 13 is started to drive the roller 14 to rotate, so that the sheared steel wire moves to the right, so that the sheared steel wire is separated, effectively avoiding the knife sticking phenomenon during the steel wire shearing process, improving the steel fiber processing efficiency, and facilitating the use of the staff.

[0030] The second implementation method:

[0031] Based on the first embodiment, this embodiment adds a slide groove 16, a slider 17, a limiting plate 18 and a positioning plate 19, and the rest of the parts are consistent with the first embodiment.

[0032] Figure 5 and Figure 6 It is shown that: a plurality of slide grooves 16 are opened at the left end of the workbench 1, and a slider 17 is slidably connected in the slide groove 16. The slide groove 16 and the slider 17 are used in combination to facilitate the installation of a limiting plate 18. The upper ends of two adjacent sliders 17 with a larger spacing are fixedly connected with a limiting plate 18.

[0033] Figure 7 It is shown that: the limiting plate 18 is in an inverted U shape, and the lateral inner wall of the limiting plate 18 is fixedly connected with multiple positioning plates 19 through multiple mounting rods. The positioning plate 19 is arched as a whole. The positioning plate 19 can limit the steel wire moving to the right, effectively preventing the steel wire from being displaced during the movement, and can also effectively prevent the uncut steel wire from sticking to the surface of the shear knife 5.

[0034] When in use, the slider 17 is inserted into the slide groove 16 so that the limiting plate 18 is located above the workbench 1, and multiple steel wires are inserted into the limiting plate 18 so that they are located below the positioning plate 19, so that the steel wires will not be displaced during the cutting process, making it convenient for the staff to cut the multiple steel wires neatly and convenient for the staff to use.

[0035] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
