The technology and principle of cold forming tee machine
Cold forming tee machine principle: first pipe into the mold cavity in the hydraulic cylinder under the action of the plunger head is pressed into the both ends of the pipe, the pipe sealing cavity, and then the liquid medium into the pipe cavity through the liquid channel in the head; at this time, the upper mould moves downwards, and the lower die cavity to form together finally closed, high pressure pump and valve control liquid pressure increasing, push push pipe, pipe wall deformation and gradually and the mold wall tightly, forming tee. |
