[0034] In this embodiment, the fixing device includes mold glue; when in use, the mold glue is used to fix the fixing part 3 of the mold 2 in the fixing groove 6 to achieve the purpose of fixing the mold 2 in the mounting seat 1; in addition, the fixing method can also adopt the method of interference fit between the fixing part 3 and the fixing groove 6 to fix the fixing part 3 and the fixing groove 6.

[0035] In this embodiment, the four right-angled sides of the shearing portion 4 form the shearing edges 8 of the grinding tool.

[0036] In this embodiment, the fixing device is two mounting seats 1 respectively arranged on the left and right sides of the fixing part 3, and the fixing device includes a slide plate 9 slidably arranged in the mounting seat 1 along the left and right directions. The upper end surface of the slide plate 9 is slidably provided with an ejector rod 10, and the lower end surface of the slide plate 9 is slidably provided with a tightening rod 11. A driving device is provided between the ejector rod 10 and the tightening rod 11, and the driving device is used to drive the ejector rod 10 and the tightening rod 11 to move synchronously in opposite directions. The inner ends of the ejector rod 10 and the tightening rod 11 are provided with a driving inclined surface 12, and the left and right sides of the fixing part 3 of the mold 2 are provided with a driving groove 13, and the driving groove 13 includes an upper inclined surface 14 and a lower inclined surface 15 that are symmetrical in the upper and lower directions; a moving device is also provided on the mounting seat 1, and the moving device is used to drive the slide plate 9 to drive the ejector rod 1 0 and the pushing rod 11 move left and right synchronously; when in use, the mold 2 is placed in the mounting groove 5 of the mounting seat 1, and then the sliding plate 9 is driven by the moving device to slide inward, so that the ejector rod 10 and the pushing rod 11 both enter the set position in the driving groove 13, and then the pushing rod 11 is driven inward by the driving device, and the ejector rod 10 moves outward synchronously, and the pushing rod 11 moves inward and contacts the lower inclined surface 15 of the driving groove 13 through the driving inclined surface 12, forcing the fixing part 3 of the mold 2 to move downward, so that the fixing part 3 of the mold 2 presses the inner bottom wall of the fixing groove 6 downward, so that the fixing part 3 of the mold 2 is fixed in the fixing groove 6, and the mold 2 is fixed; when the mold 2 needs to be replaced, the pushing rod 11 is driven by the driving device to move outward, and the ejector rod 1 0 moves inward synchronously, the ejector rod 10 moves inward and contacts the upper inclined surface 14 of the driving groove 13 through the driving inclined surface 12 of the ejector rod 10, forcing the mold 2 to move upward. At this time, the mold 2 is manually clamped, and then the slide plate 9 is driven outward by the moving device, thereby driving the ejector rod 10 and the tightening rod 11 to move outward until the ends of the ejector rod 10 and the tightening rod 11 are hidden in the mounting seat 1. Then, the mold 2 is manually clamped and lifted upward to remove the mold 2 from the mounting groove 5 of the mounting seat 1, thereby facilitating the disassembly of the mold 2. The fixing method of this embodiment can be used in combination with the fixing method of mold glue. When the mold glue is used to fix the mold 2, it is not convenient to disassemble. The driving device drives the ejector rod 10 to move inward so that the ejector rod 10 passes through the driving inclined surface 1 2 cooperates with the upper inclined surface 14 of the driving groove 13 to push the mold 2 upward, first realizing the separation of the fixing part 3 of the mold 2 from the mounting groove 5, making it easier to disassemble the mold 2; the movement principle of the ejector rod 10, the tightening rod 11 and the fixing part 3 of the mold 2 is as follows: when fixed, the tightening rod 11 moves inward, and the ejector rod 10 moves outward synchronously, and the inward movement of the tightening rod 11 forces the fixing part 3 to move downward, which is exactly adapted to the distance the ejector rod 10 moves outward to separate from the upper inclined surface 14 of the mounting groove 5; when disassembling, the ejector rod 10 moves inward, and the tightening rod 11 moves outward synchronously, and the inward movement of the ejector rod 10 forces the fixing part 3 to move upward, which is exactly adapted to the distance the tightening rod 11 moves outward to separate from the lower inclined surface 15 of the mounting groove 5.

[0037] In this embodiment, the driving device includes a gear 16 arranged in the skateboard 9, the gear 16 is rotatably connected to the skateboard 9, and a rack 17 is fixedly provided on the side surface close to the ejector rod 10 and the tightening rod 11 along the left and right directions, and the gear 16 is engaged with the rack 17 of the ejector rod 10 and the tightening rod 11; the rotating gear 16 drives the ejector rod 10 and the tightening rod 11 to move synchronously in the opposite direction through the rack 17.

[0038] In this embodiment, a driving rod 18 is coaxially fixed to the front end of the rotating shaft of the gear 16, and the front end of the driving rod 18 is located in a slide groove 19 opened along the left and right directions on the front side of the mounting seat 1. In order to facilitate the determination of whether the moving device drives the slide plate 9 to move inward and outward to the set position, two indicator marks 20 are opened on the front side of the mounting seat 1 above the slide groove 19. When the moving device drives the slide plate 9 to move inward, when the front end of the driving rod 18 moves to the inner indicator mark 20, it means that the slide plate 9 drives the ejection rod 10 and the tightening rod 11 to move to the set position; when the moving device drives the slide plate 9 to move outward, when the front end of the driving rod 18 moves to the outer indicator mark 20, it means that the slide plate 9 drives the ejection rod 10 and the tightening rod 11 to move to the set position.

[0039] In order to achieve the purpose of moving the sliding plate 9 left and right, in this embodiment, the outer surface of the driving rod 18 located inside the slide groove 19 is rotatably connected with a slider 21, and the slider 21 is slidably connected to the mounting seat 1 along the left and right directions through the slide groove 19. The upper end surface of the slider 21 is fixedly provided with a driving block 22, and the moving device includes a threaded rod 23 connected to the inner thread of the driving block 22, and the threaded rod 23 is rotatably connected to the mounting seat 1; by rotating the threaded rod 23, the driving block 22 is driven to move left and right, so that the driving block 22 drives the driving rod 18 to move left and right through the slider 21, and the driving rod 18 drives the sliding plate 9 to move left and right, thereby achieving the purpose of driving the sliding plate 9 to move left and right.

[0040] In this embodiment, the outer end of the threaded rod 23 extends to the outer side surface of the mounting seat 1 and is fixedly provided with a hexagonal driving cap 24. The hexagonal driving cap 24 is driven by a tool to drive the threaded rod 23 to rotate, thereby achieving the purpose of driving the threaded rod 23 to rotate.

[0041] In order to prevent the drive rod 18 from rotating accidentally, in this embodiment, the side thread of the slider 21 is connected with a top screw 25. By turning the knob top screw 25, the end of the top screw 25 is in contact with the outer surface of the drive rod 18 to achieve the purpose of locking the rotation of the drive rod 18. The knob top screw 25 is turned so that the end of the top screw 25 is separated from the outer surface of the drive rod 18, thereby achieving the purpose of allowing the drive rod 18 to rotate.

[0042] In this embodiment, two mounting holes 26 are provided on the upper end surface of the mounting base 1 , and the mounting base 1 is fixed to the execution end of the press by means of bolts and the mounting holes 26 , thereby achieving the installation of the mold 2 .

[0043] In this embodiment, the mold 2 and the mounting base 1 are both made of Cr12MoV.

[0044] The working principle of the present invention is as follows: when in use, first fix the fixing part 3 of the mold 2 in the fixing groove 6 by the mold glue, and the shearing part 4 is located in the accommodating groove 7, and then install the mounting base 1 on the execution end of the press through the mounting hole 26 and the bolt, so that the execution end of the press drives the mold 2 to press downward through the mounting base 1, so that the shearing part 4 shears and forms the raw material, completing the production of the photovoltaic bracket hardware connector. By replacing different molds 2, hardware connectors of photovoltaic brackets of different models can be produced, realizing one mold for multiple uses and saving the production cost of the mold 2; the fixing part 3 of the mold 2 is fixed to the fixing groove 6 of the mounting base 1 and can also be fixed by the tightening rod 11. The specific operation method is to first rotate the threaded rod 23 to drive the slider 21 to move outward, so that the slider 21 drives the slide plate 9 to move outward through the driving rod 18, thereby making the tightening rod 3 and 3. The cam 24 is pressed against the top of the workpiece 3 and the workpiece 3 is then moved to the left of the workpiece 3. When the workpiece 3 is in the state of being moved, the cam 24 is pressed against the top of the workpiece 3 and the workpiece 3 is moved to the right of the workpiece 3. When the workpiece 3 is in the state of being moved, the workpiece 3 is moved to the left of the workpiece 3.
