Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a fast-adjustable rotating lifting bracket. Background Art

[0002] In actual use of the bending machine, due to the different workpieces being processed, the height of the bracket is often adjusted to make it in the working position or in the avoidance position. When the bracket of the bending machine is in the working position, the support surface is required to be flush with the lower die surface. When it is in the avoidance position, the long side is required to be rotated and stored close to the lower die to avoid affecting the worker's operation. At this time, it is very important whether the bracket is easy to adjust and clamp quickly and reliably. Advanced adjustment methods can well reduce the labor intensity of workers, improve work efficiency and product qualification rate. At present, one way on the market is that the traditional mode adopts a tripod with a U-shaped hole structure and a screw fixed connection. For example, the patent disclosure document CN211679420U adopts a tripod structure; in this way, the bracket relies on the friction provided by the screw to ensure that the position remains unchanged. The bracket will loosen after long-term use, and the position change will affect the bending accuracy. In addition, this structure requires manual measurement of the height of the bracket and its parallelism with the lower die surface every time it is adjusted, which is cumbersome and inefficient.

[0005] Furthermore, the outer wall surface of the guide support rod is also provided with a guide groove B, which is arranged parallel to the guide groove A, the bottom end of the guide groove B is connected to the arc groove, and the guide pin matches the guide groove B.

[0006] Furthermore, the length of the guide groove B is greater than the diameter of the guide pin.

[0007] Furthermore, the arc angle of the arc-shaped groove is 60-120 degrees.

[0016] See also Figure 1-3 The present embodiment is a quick-adjustable rotating lifting bracket, comprising a mounting seat 4, a sliding cavity arranged in the vertical direction is provided in the mounting seat 4, the sliding cavity runs through the mounting seat 4, a guide support rod 2 is installed in the sliding cavity, the guide support rod 2 is slidably connected to the inner wall of the sliding cavity, a supporting plate 1 is installed at the top of the guide support rod 2, a guide groove A21 arranged in the vertical direction is provided on the outer wall of the guide support rod 2, a transversely arranged arc groove 22 is provided at the bottom of the guide groove A21, the arc groove 22 is connected to the guide groove A21, and a guide pin 5 extending into the sliding cavity is installed on the mounting seat 4, and the guide pin 5 matches the guide groove A21 and the arc groove 22.

[0017] Furthermore, the outer wall surface of the guide support rod 2 is also provided with a guide groove B23, which is arranged parallel to the guide groove A21, and the bottom end of the guide groove B23 is connected to the arc groove 22, and the guide pin 5 matches the guide groove B23.

[0018] Furthermore, the length of the guide groove B23 is greater than the diameter of the guide pin 5 .

[0019] Furthermore, the arc angle of the arc-shaped groove 22 is 90 degrees. Specifically, it can be designed to have different angles according to actual use conditions, usually within the range of 60-120 degrees.

[0020] Furthermore, a limit baffle is installed at the bottom end of the guide support rod 2, and the diameter of the limit baffle is larger than the inner diameter of the sliding cavity.

[0021] Furthermore, a guide belt 3 is respectively installed at the upper end and the lower end of the sliding cavity, and the guide belt 3 cooperates with the guide support rod 2.

[0022] Furthermore, the mounting seat 4 is fixedly connected to the machine platform 9 of the bending machine through T-nuts 8 and bolts 6.

[0023] When the utility model is used, when the support plate 1 needs to be raised, the guide support rod 2 is moved upward along the sliding cavity. After moving to the top, the guide pin 5 is located at the bottom end of the guide groove A21. At this time, the support plate 1 is rotated with the guide support rod 2 itself as the axis, and the guide support rod 2 also rotates accordingly. The guide pin 5 automatically moves along the arc groove 22. When the guide support rod 2 rotates 90 degrees, the guide pin 5 enters the guide groove B23 accordingly. Under the action of gravity, the guide support rod 2 falls down a little height along the guide groove B23. At this time, the guide pin 5 is stuck in the guide groove B23, so that the guide support rod 2 cannot rotate. At the same time, the top surface of the support plate 1 at the upper end is just flush with the lower mold surface on the bending machine table 9; When it is necessary to retract the support plate 1, first pull up the guide support rod 2 to make the guide pin 5 enter the arc groove 22, then rotate it in the opposite direction to make the guide pin 5 enter the guide groove A21, and finally make the guide support rod 2 slide downward along the guide groove A21, and finally the guide pin 5 will be against the top of the guide groove A21. At this time, the upper end of the support plate 1 is lower than the height of the lower mold surface.
