DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] Please refer to Figures 1 to 10 The present application provides a technical solution: a plate shearing device for metal mold production and its process, which comprises a body 1 prepared by a plate shearing machine. The plate shearing machine adopts existing technologies such as Q11 series hydraulic plate shearing machine, which is a common existing technology and will not be described here. The front end face of the body 1 is provided with an operating table for placing the metal plate to be sheared. The operating table 1 is provided with an adjusting assembly 2 for adjusting the shearing angle of the metal plate. The adjusting assembly 2 comprises a first translation plate 4 and a second translation plate 5. The rear back surfaces of the first translation plate 4 and the second translation plate 5 are connected by a stabilizing plate 6 through welding. The first translation plate 4 and the second translation plate 5 are assembled into a whole through the stabilizing plate 6, and the first translation plate 4 and the second translation plate 5 can simultaneously and stably translate when the entire adjusting assembly 2 is pushed to move in the later stage.

[0039] The operation table of the machine body 1 is provided with two translation grooves 3, the first translation plate 4 and the second translation plate 5 have the same length, width and height, and the width of the first translation plate 4 and the second translation plate 5 is the same as that of the two translation grooves 3. The translation grooves 3 extend from the top of the operation table of the machine body 1 to the left and right side walls of the machine body 1 and are located on the left and right sides of the shearing cutter travel route on the machine body. The first translation plate 4 and the second translation plate 5 are placed in the translation grooves 3 on the operation table of the machine body 1, so that the first translation plate 4 and the second translation plate 5 maintain straight line motion. Through the cooperation of the translation grooves 3 and the stable plate 6, it is convenient for the U-shaped frame composed of the first translation plate 4, the second translation plate 5 and the stable plate 6 not to be deformed during the process of moving the metal plate by the rotating plate 11, so as to avoid the cutting angle of the metal plate being deviated due to the movement of the first translation plate 4 and the second translation plate 5.

[0040] The first translation plate 4 is provided with an angle adjusting assembly for adjusting the inclination angle of the metal plate. The angle adjusting assembly comprises a rotating shaft 7. The first translation plate 4 is provided with a mounting groove, and the opening of the mounting groove is located on the right side of the first translation plate 4. The rotating shaft 7 is placed in the mounting groove. A circular groove with the same diameter as the rotating shaft 7 is arranged on the inner wall of the bottom end of the mounting groove. A through hole with the same diameter as the rotating shaft 7 is arranged on the top plate of the mounting groove. The bottom end of the rotating shaft 7 is inserted into the circular groove in the mounting groove, and the top end of the rotating shaft 7 extends above the first translation plate 4 through the through hole in the mounting groove. A pointer is welded and mounted on the outer wall above the rotating shaft 7.

[0041] An angle ruler is mounted on the top end of the first translation plate 4. The angle ruler is in the shape of a circular ring, and the inside of the circular ring is marked with angle data. The circular ring is placed around the rotating shaft 7 and the pointer and is fixedly mounted on the top end of the first translation plate 4 by welding. The rotating shaft 7 drives the pointer to rotate synchronously during rotation. By observing the rotation amplitude of the pointer and recording the different positions of the pointer before and after stopping, the rotation amplitude of the rotating shaft 7 and the rotating plate 11 can be obtained. When the metal plate is inclined and cut, the inclination amplitude of the metal plate can be obtained by following the rotating shaft 7 and the pointer rotating with the rotating plate 11, and whether it is the same as the required inclination angle of the metal plate.

[0042] The outer wall of the rotating shaft 7 is welded with a mounting block 8, the right side of the mounting block 8 is provided with a rotating plate 11 for adjusting the inclination angle of the metal plate, a rotating rod 9 is arranged between the rotating plate 11 and the mounting block 8, the left and right sides of the rotating rod 9 are rotatably connected with the mounting block 8 or the rotating plate 11 through a rotating connecting ring, by controlling the rotation of the rotating rod 9, when the metal plate is too thick and does not need to be obliquely cut when placed on the operating table of the machine body 1, the rotating plate 11 can be turned over by controlling the rotation of the rotating rod 9, at this time, the worker pushes the metal plate to the side farthest from the metal plate on the operating table to move the metal plate under the cutting knife for cutting, which increases the distance between the worker and the cutting knife during cutting, avoiding safety accidents caused by the heavy weight of the thick metal plate.

[0043] A square block is welded on the top end side wall of the rotating rod 9, a limiting frame 10 is arranged between the mounting block 8 and the rotating plate 11 to limit the rotation of the rotating plate 11, the limiting frame 10 is in U-shaped, and the opening of the U-shaped limiting frame 10 faces downward, the opening width size of the limiting frame 10 is the same as the width size of the square block, and clamping blocks are welded on the left and right side walls of the limiting frame 10, the top end of the mounting block 8 and the rotating plate 11 is also provided with a clamping groove matched with the clamping block, after the limiting frame 10 is sleeved on the outer wall of the square block on the rotating rod 9, the clamping block is synchronously clamped into the clamping groove, which can limit the rotation of the rotating plate 11, avoiding the rotation of the rotating plate 11 itself when adjusting the angle of the metal plate.

[0044] The right side of the rotating plate 11 is provided with a telescopic plate 12 for self-adaptive position adjustment, the rotating plate 11 is a hollow plate, and the right side wall of the rotating plate 11 is provided with an opening with the same length and width size as the telescopic plate 12, the telescopic plate 12 extends into the inner cavity of the rotating plate 11 through the opening, and the right side inner wall of the rotating plate 11 and the left side of the telescopic plate 12 are connected through a spring, which facilitates the extension or retraction of the telescopic plate 12 into the inner cavity of the rotating plate 11 when the rotating plate 11 rotates to adjust the position, so that it can be between the first connecting screw 14 and the U-shaped frame 13, facilitating the fixation of the position of the telescopic plate 12 and the rotating plate 11 later.
