Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 One embodiment provided by this utility model:

[0024] A highly adaptable disc shear includes a shearing table 100, with a table surface 101 mounted on its surface. A side frame 110 is fixed to the side of the shearing table 100, and a hanger 120 is horizontally supported on the upper part of the side frame 110 via a suspension rod 121. A shearing adjustment mechanism 200 is mounted on the upper part of the shearing table 100 and the lower part of the hanger 120. A turntable auxiliary mechanism 300 is mounted on the side of the shearing table 100. The shearing adjustment mechanism 200 includes an upper shearing disc 210 with corresponding upper and lower tips and... The lower shearing disc 220, and the upper shearing disc 210 and the lower shearing disc 220 are respectively inserted with a rotating shaft 1 211 and a rotating shaft 221. The surfaces of the rotating shaft 1 211 and the rotating shaft 221 are both fixed with a movable slide rod 240. The outer wall of the movable slide rod 240 is fitted with a limiting slide sleeve 250. The turntable auxiliary mechanism 300 includes an auxiliary turntable 310. The bottom of the auxiliary turntable 310 is supported by a rotating shaft 320. A rubber pressure head 340 is provided above the auxiliary turntable 310.

[0025] As described in more detail in this embodiment, the movable slide rod 240 has a hexagonal cross-section, and the limiting slide sleeve 250 has a corresponding through groove inside. The outer wall of the limiting slide sleeve 250 is threaded with a limiting pin 251, and the inner end of the limiting pin 251 abuts against the outer wall of the movable slide rod 240. The two sets of limiting slide sleeves 250 abut against and support the outer walls of the upper shear disc 210 on both sides. An inner washer 252 is fixed on the side of the limiting slide sleeve 250 near the outer wall of the upper shear disc 210. The lower shear disc 220 is similarly provided on both sides. This facilitates auxiliary sliding adjustment and limiting support according to usage needs, making subsequent operation more convenient. The three sets of upper shear discs 210, lower shear discs 220, and limiting slide sleeves 250 are also respectively supported and assembled on the outer walls of the first rotating shaft 211 and the second rotating shaft 221. The middle of the table 101 has a groove for the upper shear disc 210. The square groove 102 corresponding to the lower shearing disc 220, the upper shearing disc 210 and the lower shearing disc 220 are respectively supported and assembled at the lower part of the hanger 120 and the upper part of the shearing table 100 by bearing 213 and bearing 223 respectively. The upper shearing disc 210 and the lower shearing disc 220 are respectively equipped with meshing gear 212 and gear 222 on the right side. The upper shearing disc 210 is equipped with a reducer 230 through a coupling. The input end of the reducer 230 is equipped with a motor 231. The bottom of the reducer 230 and the motor 231 are supported and assembled inside the side frame 110 by a side support 232. In this way, it is easy to stably output torque for transmission during assembly and use. At the same time, with the setting of three sets of upper shearing discs 210 and lower shearing discs 220, it is easy to perform synchronous multi-strip shearing, making operation and use more convenient.

[0026] As described in more detail in this embodiment, a limiting baffle 400 is vertically mounted on the surface of the shearing table 100, and locking pins 410 are threadedly inserted on both sides of the limiting baffle 400. A lower clamping foot 420 is fitted on the bottom of the locking pin 410. A clamping washer 421 is fixed on the surface of the lower clamping foot 420 and the bottom of the limiting baffle 400. An upper torsion cap 411 is integrally fixed on the upper end of the locking pin 410, and a fastening nut 412 is threaded on the outer wall of the locking pin 410. A back support plate 430 is supported on the back of the limiting baffle 400. In this way, it is convenient to limit and support the edge of the material according to the needs of use, making the subsequent shearing operation more convenient and facilitating the horizontal pushing shearing operation.

[0027] As described in more detail in this embodiment, a lower sleeve 311 corresponding to the rotating shaft 320 is fixedly provided at the center of the bottom of the auxiliary turntable 310. The lower sleeve 311 is fitted onto the upper end of the rotating shaft 320 and fastened with screws. The middle part of the rotating shaft 320 is assembled inside the side of the shear table 100 through a bearing 321 with a seat. The lower end of the rotating shaft 320 is equipped with a reducer 330 through a coupling. The input end of the reducer 330 is equipped with a motor 331. The bottom of the reducer 330 and the motor 331 are supported on the lower side of the shear table 100 through a bottom support 332. In this way, during assembly and use, it is convenient to perform auxiliary transmission according to the needs of use, and it is convenient to drive the material to perform circumferential motion, thereby realizing circular shearing.

[0028] As described in more detail in this embodiment, a circular groove 103 corresponding to the auxiliary turntable 310 is provided on the left side of the table 101. The lower part of the rubber pressure head 340 is hemispherical, which facilitates the support and assembly of the auxiliary turntable 310. Subsequently, the rubber pressure head 340 presses down under the rubber hemisphere in conjunction with the auxiliary turntable 310 to clamp the material, which facilitates subsequent transmission. An upper support shaft 341 is fixedly provided at the upper end of the rubber pressure head 340, and an upper rotating cylinder 342 is threaded onto the outside of the upper support shaft 341. The upper rotating cylinder 342 is connected to a belt in the middle. The bearing 343 is supported on the upper part of the outer wall of the side end of the hanger 120. The upper support shaft 341 is threaded with a limiting nut 344, and two sets of limiting nuts 344 are respectively supported at the upper and lower ends of the upper rotating cylinder 342. The upper end of the upper support shaft 341 is fixed with an upper torsion block 345. In this way, it is convenient to adjust the up and down movement of the upper support shaft 341 during assembly and use. It is also convenient to adjust the pressure according to the thickness when clamping materials. It is also convenient to raise the rubber pressure head 340 to a higher position when not in use, so as not to cause interference to subsequent use.

[0029] Working Principle: Motor 2 (331) and Motor 1 (231) are connected to the corresponding power distribution control circuit for subsequent power supply control as needed. Then, according to material shearing requirements, with the cooperation of the moving slide rod 240, loosening the limit screw 251 facilitates the sliding of the limit sleeve 250, thereby facilitating the adjustment of the positions of the upper shear disc 210 and the lower shear disc 220. Subsequently, tightening the limit screw 251 limits the position of the limit sleeve 250, maintaining the limit support for the upper shear disc 210 and the lower shear disc 220, facilitating subsequent rotation and shearing. This allows for auxiliary selection and adjustment of the three sets of upper and lower shear discs 210 and 220 according to usage requirements. Simultaneously, with the cooperation of the limit baffle 400, the locking screw 410 and the lower clamping foot 420... The limiting clamp on the side of the table 101 facilitates support of the material's side edge during shearing, making horizontal shearing more convenient. If circular shearing is required, the material is placed on the upper part of the auxiliary turntable 310. Then, with the cooperation of the upper support shaft 341 and the upper rotating cylinder 342, the rubber pressure head 340 and the auxiliary turntable 310 squeeze and clamp the material. Then, with the cooperation of the upper torsion block 345, the limiting nut 344 is tightened to facilitate the limiting between the upper support shaft 341 and the upper rotating cylinder 342. Subsequently, during rotation, the upper rotating cylinder 342 rotates accordingly through the cooperation of the seated bearing 343, thus facilitating circular rotation. Then, circular shearing is performed with the cooperation of the upper shearing disc 210 and the lower shearing disc 220. The operation ends here.
