[0002] The slitting machine is a special shearing machine, which uses an array of circular blades to rotate relative to each other on two fixed shafts to squeeze and shear (to make it exceed the tensile and yield limits of the plate) to separate the plate into strips. The rotating upper blade and the rotating lower blade are locked by the hydraulic locking device to stabilize the blade gap and protect the blade from biting. Only in this way can shearing force be applied to metal plates of various thicknesses to make the plates be cut into strips according to the required size. The slitting machine is a type of forging machine, and its main function is in the metal processing industry.

Then the hydraulic cylinder can be started, and the output end thereof will drive the limit block to be inserted into the inner wall of the limit groove. Through the outward thrust from all directions, the cutter wheel can be fixed and limited on the outer wall of the connection frame.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0027] like Figures 1 to 4 As shown, a hydraulic locking device for a slitting machine blade comprises a base 1, a support rod 2 fixedly connected to the bottom end of the base 1, a limit adjustment mechanism 31 is arranged at the top end of the support rod 2, a fixing mechanism 32 is arranged on the limit adjustment mechanism 31, the limit adjustment mechanism 31 comprises a connecting shaft 311 rotatably arranged at the top end of the support rod 2, a rolling groove 312 is arranged on the outer wall of the connecting shaft 311, rotating grooves 313 are arranged on both sides of the inner wall of the rolling groove 312, a ball 314 is rotatably arranged on the inner wall of the rolling groove 312, a connecting plate 315 is movably connected to the outer wall of the ball 314, and the connecting plate 31 The outer wall of the support connecting plate 316 is fixedly connected, and a positioning groove 317 is provided on the outer wall of the support connecting plate 316. The end of the connecting plate 315 away from the ball 314 is fixedly connected to the connecting frame 318. The outer wall of the connecting frame 318 is fixedly connected to the handle 319. The inner wall of the rotating groove 313 is provided with a sliding hole. The inner wall of the sliding hole is fixedly connected to a spring 3110. The end of the spring 3110 away from the inner wall of the sliding hole is fixedly connected to a sliding column 3111. The outer wall of the sliding column 3111 is slidably connected to the inner wall of the sliding hole. The end of the sliding column 3111 away from the spring 3110 is fixedly connected to a locking protrusion 3112.

[0028] Furthermore, the outer wall of the connecting plate 315 fits snugly with the inner walls of the rolling groove 312 and the rotating groove 313. There are several rotating grooves 313, which are evenly and equidistantly distributed on the inner wall of the rolling groove 312. In this way, when the connecting plate 315 moves on the inner walls of the rolling groove 312 and the rotating groove 313, it fits tightly, thereby improving the stability of the connecting frame 318 during the movement and rotation process.

[0029] Furthermore, there are several card protrusions 3112, which are evenly and equidistantly distributed on the inner wall of the rotating groove 313. By setting up multiple card protrusions 3112, multi-level adjustment can be performed, so that the position of the blade 326 can be adjusted in multiple positions, thereby improving its applicability.

[0030] Furthermore, the outer wall of the card protrusion 3112 is in the shape of an arc, and the outer wall of the card protrusion 3112 fits snugly against the inner wall of the positioning groove 317. Through the arc setting, the card protrusion 3112 can be squeezed by the pulling extrusion force, thereby facilitating the staff to adjust the connecting frame 318 left and right.

[0031] The fixing mechanism 32 includes a support plate 321 fixedly connected to the outer wall of the connecting frame 318, and the support plate 321 is fixedly connected to a hydraulic cylinder 322 at one end away from the connecting frame 318. The output end of the hydraulic cylinder 322 is fixedly connected to a limiting block 323, and the outer wall of the limiting block 323 is clamped with a cutter wheel 324. A limiting groove 325 is provided on the inner outer wall of the cutter wheel 324, and the outer wall of the limiting block 323 is clamped on the inner wall of the limiting groove 325. The outer wall of the cutter wheel 324 is fixedly connected with a blade 326.

[0032] Furthermore, there are four hydraulic cylinders 322 , which are arranged in groups of two in a symmetrical structure on the outer wall of the connecting frame 318 , so that the cutter wheel 324 can be fixed and limited in four directions, thereby further improving the fixing stability of the cutter wheel 324 .

[0033] Furthermore, the outer wall of the limiting block 323 fits snugly with the inner wall of the limiting groove 325 , so that when the limiting block 323 is inserted into the limiting groove 325 , it can fit tightly with the inner wall of the limiting groove 325 , thereby ensuring stability after being snap-fitted and fixed.

[0034] The implementation principle of the hydraulic locking device for the slitting machine blade of the present embodiment is as follows: first, align the ball 314 in the connecting frame 318 with the rolling groove 312 opened on the outer wall of the connecting shaft 311, and then insert it therein, the ball 314 will roll on the inner wall of the rolling groove 312, thereby driving the connecting frame 318 to move on the outer wall of the connecting shaft 311. When it moves to the position of the rotating groove 313, the handle 319 can be held, and then the connecting frame 318 can be driven to rotate. When rotating, the connecting plate 315, the ball 314 and the supporting connecting plate 316 can be driven to rotate. At this time, the connecting plate 315 and the ball 314 will rotate on the inner wall of the rotating groove 313. During the rotation of the supporting connecting plate 316, the connecting plate 315 and the ball 314 will contact and squeeze the card protrusion 3112. The squeezed card protrusion 3112 will drive the sliding column 3111 to move toward the inner wall of the sliding hole opened on the outer wall of the connecting shaft 311. At the same time, the sliding column 3111 will squeeze the spring 3110 during the movement. The support link 316 is squeezed and compressed, and as the support link plate 316 continues to move, the positioning groove 317 can be driven to move to the upper position of the card protrusion 3112. At this time, the spring 3110 can rebound and reset, and then push the sliding column 3111 and the card protrusion 3112 to insert into the inner wall of the positioning groove 317, so as to limit and fix the connecting frame 318. When it is necessary to adjust the movement of the connecting frame 318, the connecting frame 318 can be adjusted by the rotating groove 313 on the basis of the limit of the card protrusion 3112. The limiting function is that when the connecting frame 318 needs to be moved, the connecting frame 318 can be rotated in the opposite direction so that the inner wall of the positioning groove 317 squeezes the card protrusion 3112, so that the card protrusion 3112 is separated from the inner wall of the positioning groove 317, and then the connecting plate 315 is driven to rotate to the rolling groove 312, and then the connecting frame 318 is pushed to move on the inner wall of the rolling groove 312 until it moves to the rolling groove 312 at the required position, and then the above limiting and fixing process is repeated to adjust the limiting position of the connecting frame 318.

[0035] After the connecting frame 318 is limited and fixed, the cutter wheel 324 can be sleeved on the outer wall of the connecting frame 318, so that the limit groove 325 opened on the inner outer wall is aligned with the limit block 323 at the top of the hydraulic cylinder 322. Then the hydraulic cylinder 322 can be started, and its output end will drive the limit block 323 to be inserted into the inner wall of the limit groove 325. Through the outward thrust from all directions, the cutter wheel 324 can be fixed and limited on the outer wall of the connecting frame 318.
