Description
Technical Field
The utility model relates to a tubular product production technical field, especially a simple and easy multipurpose's tubular product expansion device.
Background
When the quality of the pipe is inspected, the pipe expanding experiment of the pipe needs to be performed mostly, but a small number of customers require to perform pipe expanding experiments in various forms in order to simulate the practical scene of the pipe, namely, the whole pipe is expanded in equal proportion, and therefore the quality of the pipe is verified.
Most of the existing pipe expanding devices can only expand the pipe, only can expand the end part of the pipe into a horn shape according to a certain multiple, and cannot expand the whole pipe by a corresponding multiple. Some devices for expanding the pipes are also available in the market, but the pipe expanding devices are complex in structure, huge in structure and high in cost, are suitable for pipe expanding experiments of large-batch pipes, and are not suitable for pipe expanding experiments of a small amount of pipes.

In order to solve the technical problem, the utility model adopts the following technical proposal.
A simple and multipurpose pipe expanding device comprises a hydraulic mechanism for expanding pipes and a hydraulic controller for controlling the hydraulic mechanism to work; the hydraulic mechanism is provided with a three-jaw chuck for fixing a pipe to be expanded, and an expansion mechanism for expanding the pipe is arranged above the three-jaw chuck through an inverted L-shaped bracket; the expansion mechanism comprises an oil cylinder arranged on the bracket, an expansion pipe shaft for expanding the pipe is arranged on a telescopic rod of the oil cylinder through a bolt, and a hydraulic oil inlet and outlet pipe of the oil cylinder is connected with a hydraulic oil inlet and outlet end of the hydraulic mechanism; the end part of the telescopic rod of the oil cylinder is also provided with a displacement sensor for detecting the descending distance of the pipe expanding shaft, the output end of the displacement sensor is connected with the input end of a hydraulic controller, and the output end of the hydraulic controller is connected with the input end of a hydraulic mechanism.
Due to the adoption of the technical scheme, the utility model has the following technical progress.
The utility model discloses can set for the frock stroke as required through the accurate control tubular product expansion length of hydro-cylinder, the frock targets in place the back automatic shutdown and descends and rise, and the pipe expanding operation is accomplished to the accuracy to can also change the pipe expanding axle of different shapes or size according to the shape of expansion tubular product, it is nimble more convenient to use.
Drawings
Fig. 1 is a schematic structural view of the present invention;
wherein: 1. the hydraulic control system comprises a hydraulic mechanism, an oil cylinder 2, a hydraulic oil inlet pipe 3, a hydraulic oil outlet pipe 4, a three-jaw chuck 5, a pipe expanding shaft 5, a pipe 6 and a hydraulic controller 7.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
A simple multipurpose pipe expanding device is shown in figure 1, and comprises a hydraulic mechanism 1, an expanding mechanism and a hydraulic controller 7. The hydraulic mechanism 1 is used for expanding the pipe, the expanding mechanism is arranged above the hydraulic mechanism 1 and used for expanding the pipe, and the hydraulic controller 7 is used for controlling the hydraulic mechanism to work.
The hydraulic mechanism 1 is provided with a three-jaw chuck 4 for fixing the expanded pipe 6, and the pipe is fastened by the three-jaw chuck 4 and fixed on the hydraulic mechanism 1.
The expanding mechanism is arranged above the three-jaw chuck 4 through an inverted L-shaped support, the expanding mechanism comprises an oil cylinder 2 arranged on the support, and a hydraulic oil inlet and outlet pipe 3 of the oil cylinder 2 is connected to a hydraulic oil inlet and outlet end of the hydraulic mechanism 1. The oil cylinder is controlled by the oil output of the hydraulic mechanism, the telescopic rod of the oil cylinder 2 is arranged downwards, and the end part of the telescopic rod of the oil cylinder 2 is provided with an expanding tube shaft 5 for expanding the tube. The hydraulic controller controls the inlet and outlet of hydraulic oil through the hydraulic mechanism to control the telescopic rod of the oil cylinder to descend and ascend to drive the pipe expanding shaft to ascend and descend, so that the pipe expanding shaft can move up and down at a constant speed to expand the pipe.
The end of the telescopic rod of the oil cylinder 2 is provided with a displacement sensor for detecting the descending distance of the expanding tube shaft 5, the output end of the displacement sensor is connected with the input end of a hydraulic controller 7, and the output end of the hydraulic controller is connected with the input end of a hydraulic mechanism. In the pipe expanding process, the descending distance of the oil cylinder telescopic rod is set through the hydraulic controller, and when the descending distance of the pipe expanding shaft detected by the displacement sensor is equal to the set distance, the oil cylinder telescopic rod stops descending, so that the pipe is controlled to be expanded within a certain length.
The utility model provides an expand tub axle 5 passes through the bolt setting on the telescopic link of hydro-cylinder, can change the expand tub axle of different shapes or size according to the shape of expansion tubular product, uses more in a flexible way.
The utility model discloses when the installation, will treat through three-jaw chuck that expansion tubular product is fixed on hydraulic pressure mechanism, select suitable expander axle to install on the telescopic link of hydro-cylinder according to tubular product, through operation hydraulic controller, set up the distance that the hydro-cylinder telescopic link descends to guarantee to make the expander axle descend certain distance, carry out the expander with tubular product in certain length, treat that the expansion is accomplished the back, hydraulic pressure mechanism control cylinder telescopic link stops descending and rises, accomplishes the expansion work of tubular product.
