[0006] Furthermore, one end of a connecting rod is hinged on the screw block and the guide block at the lower end, and the other end of the connecting rod is hinged on the front wall and the rear wall of the pressure plate at the lower end; The screw block at the upper end and the guide block at the upper end are both hinged to the front wall and the rear wall of the pressure plate at the upper end.

[0007] Furthermore, the right ends of the bidirectional screws all pass through the U-shaped seat and are fixedly connected to bevel gears A at their ends, and bevel gears B are meshed and connected to the bevel gears A. A vertically arranged sliding rod is rotatably connected to the upper L-shaped plate, and the sliding rod is fixedly connected to the bevel gear B at the upper end; The L-shaped plate at the lower end is rotatably connected to a sliding sleeve, the sliding sleeve is fixedly connected to the bevel gear B at the lower end, and the sliding rod is slidably connected to the sliding sleeve; A driving motor is fixedly mounted on the right end of the support frame, and the output shaft of the driving motor extends to the left and is connected to the bevel gear A at the lower end.

[0008] Furthermore, a bidirectional cylinder is fixedly installed in the middle of the U-shaped seat at the lower end, the output shaft of the bidirectional cylinder extends to the left and right sides, and the ends are fixedly installed with moving blocks, and the top of the moving block is fixedly installed with a telescopic cylinder B, the output shaft of the telescopic cylinder B extends upward, and the ends are fixedly installed with positioning plates that contact the left and right ends of the plate.

[0009] Furthermore, a telescopic cylinder A is fixedly installed on the gantry, and the movable end of the telescopic cylinder A extends downward, and the end is fixedly connected to the middle part of the U-shaped seat at the upper end; The U-shaped seat at the lower end is fixedly mounted on the top wall of the support frame.

[0010] Furthermore, slide rails are fixedly installed on the front and rear sides of the top wall of the support frame and at the left end of the U-shaped seat, and two sliders are slidably connected to the slide rails. The four sliders form a rectangle, and the top end is fixedly mounted with a column of the conveyor body; A longitudinally arranged connecting plate is fixedly installed between the columns at the right end, and the movable end of the telescopic cylinder C is fixedly installed on the top wall of the support frame and between the slide rails. The movable end of the telescopic cylinder C extends to the right, and the end is fixedly installed on the middle part of the connecting plate.

[0011] Furthermore, a material storage box with an open top is provided on the left side of the conveyor body, and a through slot is horizontally opened on the material storage box. A telescopic cylinder D is fixedly installed on the left wall of the material storage box, and the movable end of the telescopic cylinder D extends to the left, and a push plate extending to the right is fixedly installed on the end, and the push plate passes through the through slot and is slidably connected to the inner bottom wall of the material storage box.

[0012] A method for producing a plate for processing electrical equipment, comprising the following steps: S1: Place the plate to be processed into the storage box, start the telescopic cylinder D to retract its movable end, drive the push plate to move right, and push the lowest plate along the through slot to the conveyor body; S2: Move the conveyor body to the right by telescoping cylinder C until the right end of the conveyor body is close to the left end of the lower pressure plate, and start the conveyor body to rotate the conveyor belt clockwise until the plate is moved to the lower pressure plate; S3: The conveyor body is reset to the left end, and the movable end of the telescopic cylinder B is fully extended, driving the positioning plate to move up; S4: Start the bidirectional cylinder to retract its movable end, and drive the positioning plates on both sides to move closer to each other through the moving block until the plate is positioned in the horizontal middle of the pressing plate; S5: Reset the positioning plate to its initial state, start the telescopic cylinder A to extend its movable end, and drive the upper U-shaped seat to move downward (the slide rod slides along the sliding sleeve) until the upper pressure plate contacts the plate; S6: Start the drive motor to drive the bidirectional screw at the lower end to rotate.

[0013] Compared with the prior art, the beneficial effect of the plate production device for electrical equipment processing provided by the present invention is: by setting positioning plates, after the plates are loaded, the positioning plates move up and approach each other until they abut against the side walls of the plates, thereby aligning the plates to prevent deviation from affecting the bending effect. After bending, the positioning plates on both sides move down to prevent the loading and unloading of the plates.

[0014] By setting bevel gear A, bevel gear B, sliding rod and sliding sleeve, the upper and lower sets of pressure plates can produce the same angle, thereby bending the plate; among them, the sliding rod is a square column, which can slide vertically relative to the sliding sleeve and rotate synchronously with the sliding sleeve.

[0015] By arranging the conveyor body to be able to move left and right, it is avoided that the left end of the plate abuts against the right end of the conveyor body, causing the two to affect each other during bending. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Optionally, in the above technical solution, a telescopic cylinder A12 is fixedly mounted on the gantry 11, and the movable end of the telescopic cylinder A12 extends downward, and the end is fixedly connected to the middle of the upper U-shaped seat 21; The lower U-shaped seat 21 is fixedly mounted on the top wall of the support frame 1 .

[0029] Optionally, in the above technical solution, a slide rail 51 is fixedly installed on the front and rear sides of the top wall of the support frame 1 and located at the left end of the U-shaped seat 21. Two sliders 52 are slidably connected to the slide rail 51.

The movable end of the telescopic cylinder C55 extends to the right, and the end is fixedly installed on the middle part of the connecting plate 54.

[0030] Optionally, in the above technical solution, a storage box 61 with an open top is provided on the left side of the conveyor body 5, and a through slot 62 is horizontally provided on the storage box 61. A telescopic cylinder D63 is fixedly installed on the left wall of the storage box 61, and the movable end of the telescopic cylinder D63 extends to the left, and a push plate 64 extending to the right is fixedly installed on the end, and the push plate 64 passes through the through slot 62 and is slidably connected to the inner bottom wall of the storage box 61.

[0031] A method for producing a plate for processing electrical equipment, comprising the following steps: S1: Place the plate to be processed into the storage box 61, start the telescopic cylinder D63 to retract its movable end, drive the push plate 64 to move right, and push the lowest plate along the through slot 62 to the conveyor body 5; S2: The conveyor body 5 is moved to the right by the telescopic cylinder C55 until the right end of the conveyor body 5 is close to the left end of the lower pressure plate 3. The conveyor body 5 is started to rotate its conveyor belt 50 clockwise until the plate is moved onto the lower pressure plate 3. S3: The conveyor body 5 is reset to the left end, and the movable end of the telescopic cylinder B43 is fully extended, driving the positioning plate 44 to move upward; S4: Start the bidirectional cylinder 41 to retract its movable end, and drive the positioning plates 44 on both sides to move closer to each other through the moving block 42 until the plate is positioned in the horizontal middle of the pressing plate 3; S5: Reset the positioning plate 44 to its initial state, start the telescopic cylinder A12 to extend its movable end, and drive the upper U-shaped seat 21 to move downward (the slide rod 27 slides along the slide sleeve 28) until the upper pressure plate 3 abuts against the plate; S6: Start the driving motor 29 to drive the bidirectional screw 23 at the lower end to rotate. The screw block 24 on the bidirectional screw 23 drives the lower end pressure plate 3 to rotate synchronously relative to each other through the connecting rod 241, so that the angle becomes smaller. Under the meshing of bevel gear A25 and bevel gear B26 and the sliding connection of slide bar 27 and sleeve 28, the angle of upper pressure plate 3 changes in the same way, bending the plate. S7: After the bending is completed, the upper and lower pressing plates 3 are reset, the plate is removed, and the operation of S1 is repeated to perform the same processing on the subsequent plates.

[0032] Among them, according to Figure 1 、 Figure 3It can be seen that the slide rod 27 and the slide sleeve 28 are fixedly mounted on one end of the larger end face of the bevel gear B26 through a cylindrical rod, and the cylindrical rod is rotatably connected to the L-shaped plate 22 through a bearing; Similarly, the right end of the bidirectional screw 23 is also fixedly mounted on one end of the larger end face of the bevel gear A25 through a cylindrical rod, and the cylindrical rod is rotatably connected to the U-shaped seat 21 through a bearing; Furthermore, a cylindrical sleeve is fixedly mounted on one end of the smaller end face (right end) of the lower bevel gear A25 (matched with the motor shaft by a keyway provided on the inner wall of the sleeve, or by an interference fit between the inner diameter of the sleeve and the motor shaft) and is connected to the drive motor 29; like Figure 5 The cylindrical sleeve prevents the motor shaft from being directly connected to the small end of the bevel gear A25, thus preventing the motor shaft from being directly inserted into the small end hole of the bevel gear, which may result in insufficient hole depth or excessive clearance, leading to ineffective torque transmission. It is used to increase the connection area and ensure strength and centering. Among them, the driving motor 29 is a reduction motor, which is suitable for the use scenario of the device.

[0033] The inner bottom wall of the storage box 61 is flush with the top surface of the conveyor belt 50, so that the plate can move straight.

[0034] Furthermore, a limit plate 33 is fixedly installed on the bottom wall of the hinge block 30, the top surface of the limit plate 33 is in contact with the bottom surface of the hinge block 33, and the longitudinal dimension of the limit plate 33 is larger than the longitudinal dimension of the hinge block 30, which is used to limit the rotation range of the pressure plate 3.

[0035] Furthermore, an angle ruler is fixedly installed on the front wall of the hinge block 30. The straight edge of the angle ruler is flush with the top wall of the hinge block 30, and the midpoint is collinear with the midpoint of the top surface of the hinge block 30. A pointer is fixedly installed on the front wall of the two pressure plates 3 at the lower end. The end of the pointer points to the scale value of the angle ruler. The two pointers are staggered back and forth and change with the change of the angle of the pressure plate 3. The angle of the two pointers is the angle of the angle of the pressure plate 3.

[0036] In the initial state, the pressing plates 3 are all in a straight state (i.e., the pressing plates 3 are all in contact with the limiting plates 33), the movable ends of the telescopic cylinders A12, B43, and C55 are fully retracted, and the movable ends of the bidirectional cylinders 41 and D63 are fully extended; When in use, the plate to be processed is placed in the storage box 61, and the telescopic cylinder D63 is started to retract its movable end, driving the push plate 64 to move rightward to push the lowermost plate along the through slot 62 to the conveyor body 5. Then the movable end of the telescopic cylinder D63 is completely retracted, causing the push plate 64 to move to the outer wall of the storage box 61, and the upper plate moves downward, preparing for the next plate push; The conveyor body 5 is moved to the right by the telescopic cylinder C55 until the movable end of the telescopic cylinder C55 is fully extended, so that the right end of the conveyor body 5 is close to the left end of the lower pressure plate 3. The conveyor body 5 is started to rotate the conveyor belt 50 clockwise until the plate is moved onto the lower pressure plate 3, and then the conveyor body 5 is returned to the left end. The movable end of telescopic cylinder B43 is fully extended, driving the positioning plate 44 to move upward. The bidirectional cylinder 41 is activated to retract its movable end, and the positioning plates 44 on both sides are driven closer to each other through the moving block 42 until the plate is positioned in the horizontal middle of the pressure plate 3. The positioning plate 44 is then reset to its initial state. The telescopic cylinder A12 is activated to extend its movable end, driving the upper U-shaped seat 21 to move downward (the slide rod 27 slides downward along the sliding sleeve 28) until the upper pressure plate 3 abuts the plate. The driving motor 29 is started to rotate the bidirectional screw 23 at the lower end. Under the action of the connecting structures such as the slide rod 27 and the slide sleeve 28, the upper and lower screw blocks 24 and the upper and lower guide blocks 32 approach each other. The screw block 24 drives the lower end pressure plate 3 to rotate synchronously with each other through the connecting rod 241, so that the angle becomes smaller. The angle of the upper end pressure plate 3 also changes, and the plate is bent to the specified angle. After the bending is completed, the upper and lower pressing plates 3 are reset to a straight state, the upper pressing plate 3 is moved up to the highest position, the plate is removed, and the above operation is repeated, and the subsequent plates are processed in the same way (if the bending angle of the subsequent plates is the same, the number of revolutions or working hours of the output shaft of the first bending drive motor 29 is recorded).

[0037] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
