Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to an auxiliary positioning device for a PC bending machine. Background Technology

[0002] A PC bending machine is a machine that can bend metal sheets such as PC sheets. The bending machine works by placing the metal sheet to be bent at the end of the die head, and then pressing the metal sheet downwards through the end of the punch head on the bending machine to form the shape.

[0003] In actual bending operations, auxiliary positioning devices are usually installed on the bending machine to facilitate the bending operation of metal plates. However, the positions of these auxiliary positioning devices are mostly fixed. As a result, when the metal plate bends or tilts, the positioning device cannot be matched with the bent part, thus affecting the positioning effect of the metal plate. Utility Model Content

[0027] Please see Figure 1-5 As shown, this utility model is an auxiliary positioning device for a PC bending machine, comprising:

[0028] A fixed frame 11 is fixed to the front of the bending machine, and vertical rods 12 are fixed on both sides of the top of the fixed frame 11.

[0029] The dynamic positioning component includes two connecting seats 21. The inner walls of the two connecting seats 21 are slidably disposed on the outer walls of the two vertical rods 12. The two connecting seats 21 are provided with a base 22 on opposite sides. The two connecting seats 21 are rotatably disposed with a horizontal plate 23 on opposite sides. The two horizontal plates 23 are provided with a bearing plate 24 on opposite sides. The top of the bearing plate 24 is provided with a clamping member. The two horizontal plates 23 are slidably disposed with two support shafts 25 on opposite sides. The opposite ends of the two support shafts 25 are fixedly disposed with a support frame 26. The opposite sides of the two support frames 26 are respectively fixedly disposed on both sides of the fixed frame 11.

[0030] The top of the base 22 is provided with a mold groove that is compatible with the punch head of the bending machine. The bearing plate 24 is used to place and support the metal plate to be processed. The opposite sides of the two horizontal plates 23 are provided with fixing grooves that are compatible with the support shaft 25. The horizontal plates 23 are slidably connected to the support shaft 25 through the fixing grooves. The support shaft 25, in conjunction with the support frame 26, can also provide auxiliary support for the bearing plate 24, thereby improving the overall stability of the bearing plate 24.

[0031] The clamping component includes two fixed seats 31. The top ends of the two fixed seats 31 are respectively fixedly installed on both sides of the bottom end of the bearing plate 24. A bidirectional screw 32 is provided through one side of one of the fixed seats 31. Vertical plates 33 are threaded on both sides of the outer wall of the bidirectional screw 32. A clamping seat 34 is fixedly installed at the top end of both vertical plates 33.

[0032] The bidirectional lead screw 32 is rotatably engaged with the fixed base 31, and the bottom end of the clamping base 34 contacts the top end of the bearing plate 24.

[0033] A first spring 13 is sleeved on the outer wall of the vertical rod 12. The top end of the first spring 13 is fixedly connected to the bottom end of the connecting seat 21, and the bottom end of the first spring 13 is fixedly connected to the top end of the fixing frame 11.

[0034] A through groove 241 is provided in the middle of the top of the bearing plate 24, and the inner side of the through groove 241 is slidably connected to the outer wall of the vertical plate 33.

[0035] The through groove 241 is used to limit the movement of the vertical plate 33, so that it moves horizontally along the direction of the bidirectional lead screw 32. The width of the through groove 241 is adapted to the width of the vertical plate 33.

[0036] One end of the bidirectional lead screw 32 is fixedly provided with a knob 35, and the other end of the bidirectional lead screw 32 is rotatably connected to one side of another fixed seat 31;

[0037] The outer wall of the knob 35 is provided with anti-slip threads to increase the friction between the hand and the outer wall of the knob 35, making it easier to rotate the knob 35. The knob 35 is connected to the bidirectional lead screw 32 through the fixed seat 31 for rotation, thereby improving the overall stability of the bidirectional lead screw 32 during rotation.

[0038] Working principle: The metal plate to be bent is placed on the support plate 24, so that the part of the metal plate to be bent is placed at the end of the die head of the bending machine. After being clamped and positioned by the clamping device, the metal plate is bent by the bending machine. During the bending process, the metal plate will drive the base 22 to move downward. The downward movement of the base 22 will drive the connecting seat 21 to move downward. Under the action of the support shaft 25, the downward movement of the connecting seat 21 will drive one end of the horizontal plate 23 to rotate downward and the other end to rotate upward, so that the support plate 24 is still in contact with the bent part of the metal plate. In this way, the positioning device can be dynamically adjusted to match the positioning device and the bent part, thereby ensuring the positioning effect of the metal plate.

[0039] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The buffer clamping component includes several second springs 41. One end of each of the several second springs 41 is fixedly disposed on the inner side wall of the clamping seat 34, and the other end of the several second springs 41 is provided with an auxiliary clamping seat 42.

[0041] The auxiliary clamp 42 is made of rubber.

[0042] The buffer clamping component also includes a slide bar 43, the bottom end of which is fixedly mounted on the top end of the auxiliary clamping seat 42, and the outer wall of the slide bar 43 is slidably connected to the inner top end of the clamping seat 34.

[0043] The slide bar 43 is used to guide the movement of the auxiliary clamp 42, so that it moves horizontally along the clamping seat 34. The inner top end of the clamping seat 34 is provided with a groove that matches the slide bar 43.

[0044] The top of the base 22 and the top of the bearing plate 24 are located on the same horizontal plane;

[0045] The base 22, the bearing plate 24 and the top of the bending machine die head are located on the same horizontal plane.

[0046] Working principle: When the metal plate is placed on the support plate 24 for clamping and positioning, the knob 35 is rotated. The rotation of the knob 35 drives the two vertical plates 33 to move towards each other through the two bidirectional lead screw 32. The movement of the two vertical plates 33 towards each other drives the two auxiliary clamping seats 42 to move towards each other through the two clamping seats 34 respectively. When the auxiliary clamping seats 42 contact the two sides of the metal plate, as the auxiliary clamping seats 42 continue to move, they will compress the second spring 41. The elastic action of the second spring 41 will provide buffering. In this way, the metal plate can be elastically clamped and positioned, avoiding deformation of the metal plate.
