Description
Technical field
The present invention relates to a kind of stretching device, relate in particular to a kind of copper pipe segmentation stretching device, belong to copper pipe stretching field.
Background technology
Existing transition conduit, generally adopts extra heavy pipe to weld the mode of tubule, and this mode, because there being welding procedure, easily produces leak source, and hidden danger is very large.Another kind mode is to use a machine of twisting with the fingers to twist with the fingers to beat, and dwindles the caliber of one end, and when this mode impacts because the slide block of a sth. made by twisting machine inside rotates, tubing local pressure is large, easy distortion fracture, and outward appearance is coarse, and lumber recovery is not high, and sth. made by twisting is beaten rear tube wall thickness increase, waste resource.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, a kind of copper pipe segmentation stretching device is provided, solved the problem that the coarse and tube wall thickness of leak source, easily distortion, fracture, outward appearance easily appears in traditional copper pipe segmentation stretching device.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of copper pipe segmentation stretching device, comprise support and be positioned at the drawing die on support, described drawing die is connected with described support by the sliding rail being positioned on support, described sliding rail is fixedly connected with described support, the opposite side of described sliding rail is provided with a cylinder, the cylinder barrel of described cylinder is fixedly connected with described support, and the piston rod of described cylinder is fixedly connected with described drawing die.
As further optimization of the present invention, on described cylinder, be connected with one for the high-pressure oil pump of power is provided to cylinder, described high-pressure oil pump is fixed on described support.
As further optimization of the present invention, the firm banking that described drawing die comprises fixed chuck and is fixedly connected with described fixed chuck, described drawing die is fixedly connected with the piston rod of described cylinder by firm banking.
As further optimization of the present invention, the outside of described fixed chuck is provided with the cone tank of a level.
As further optimization of the present invention, described cone tank is provided with one for cutting off the blade of copper pipe.
As further optimization of the present invention, described support is provided with one for surveying the displacement transducer of drawing die moving displacement.
As further optimization of the present invention, described support is provided with a PLC controller, and described PLC controller is connected with described drawing die, displacement transducer and high-pressure oil pump.
The invention has the beneficial effects as follows: the present invention adopts the mode of the progressive stretching of small-sized cylinder, in the situation that not changing pipe performance, stretch and there is no pad successively, stop hidden leakage defect; Operation is easy, and production efficiency is high; Smooth outer surface, ensures product quality; Can divide several times and stretch, gradual transition, reduces the noise producing when refrigerator uses a transition, can not increase wall thickness, saving resource simultaneously.
