Three-way mechanism The process of making three-way

1. Put the tube embryo into the mold.

2. The slider drives the upper die and presses down, and finally closes and releases the die.

3. The two plungers move forward and flush water into the tube embryo.

4. The two side cylinders continue to advance synchronously, and extrude the embryo tube. The supercharger injects ultra-high pressure liquid (such as water) into the embryo tube, and the hydraulic pressure at this time can reach the attainable pressure. At the same time upsetting extrusion and water bulging type tube embryo. If according to the customer's requirements, can be made under the top cylinder, to support the pipe fitting and the top function and with its rise and fall.

5. If the pressure is over pressure, the hydraulic pressure will relieve automatically within a certain time.

Upsetting extrusion process is deforming under pressure of three or more directions, which can improve the plasticity of metal forming.

During the molding operation of the three-way machine, increase the pressure of the opening and passing type, so that the roll seam between the upper and lower rollers is slightly less than the thickness, that is, the middle part of the tube billet is subjected to a small amount of calendering, so that the middle part of the slightly larger extension occurs to reduce

The relative extension of the edge, if the central extension is greater than the marginal extension, then the outlet is zigzagging upward, if less than the marginal extension, then zigzagging downward, the adjustment operation should be flat. Extension in the middle

The deformation of the molding machine is added, so that the power consumption is added, the roll wear is severe, the equipment is simple damage, when the tube blank and the roll surface has a relative slide, simple roll printing and scratching. Three way machine

Three-way machine in increasing the roller light, is to increase the length of the deformation zone of the frame, the marginal extension and the hole deformation length is inversely proportional, under possible conditions, as far as possible to increase the diameter of the roll, can make the marginal extension

Decrease. When the frame distance is large, it is necessary for the marginal extension of each frame stack to be compressed and absorbed by the final frame base, which simply causes bulges and shortens the frame distance. In essence, it is to add the number of frames, which can freely tighten and absorb the marginal extension of each frame and improve the forming conditions, but the frame distance can not be too small. It is necessary to leave enough room for manoeuvre.
