Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] As shown in the figure, the working principle of the present invention is as follows: Firstly, push the slide bar until the end of the cylindrical pin abuts against the inner wall of the first through hole. The transmission of the sliding rod through the linear rack and the first gear and the second gear can move the pawl to rotate periodically in one direction, and the pawl can always be clamped on the second gear under the action of the second tension spring , to prevent the slide bar from resetting automatically; then place one end of the unbent tube in the opening on the boss and above the cylindrical pin, and place the other end horizontally on the reference plane on the base, such as Figure 4 shown;

[0021] Then, the punch on the hydraulic machine tool works to drive the rotating plate to rotate, so that the pipe is bent to conf...

Abstract

The invention discloses a bending and blanking device. The device comprises a base (1), wherein the base (1) is provided with a reference surface (3) for placing a free end of a pipe (2) and rotating the free end of the pipe (2); the base (1) is provided with a boss (4) higher than the reference surface (3) for positioning the other end of the pipe (2); the boss (4) is provided with an opening (5) for accommodating the end part of the pipe (2); the base (1) is provided with a through hole (6) for sliding the bent pipe (2) in the vertical direction; the shape of the through hole (6) is consistent with the bending shape of the pipe (2); and the through hole (6) penetrates through the upper surface and the lower surface of the base (1) in the vertical direction, and is communicated with the opening (5) in the vertical direction. The invention provides the bending and blanking device with low maintenance cost, simple operation and no need of manual pipe taking.

Description

technical field [0001] The invention relates to the technical field of pipe bending, in particular to a device for bending and blanking. Background technique [0002] At present, the pipe bending machines on the market mainly include numerical control pipe bending machines, hydraulic pipe bending machines, etc., but the problems of high maintenance cost and complicated operation generally exist in the pipe bending machines of the prior art. In addition, the pipe bending machine in the prior art needs to put the pipe fittings into the pipe bending machine one by one, and take out the formed pipe fittings one by one after the pipe fittings are bent. It is easy to cause industrial injury to the operator who takes it out, that is to say, the pipe bending machine in the prior art also has safety problems caused by the need to manually take the pipe. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing techni...
