Description
Technical field
The present invention relates to a kind of steel pipe throat frock.
Background technology
Steel tube end part usually needs to carry out reducing processing to meet different instructions for uses.The secondary reducing of special steel tube end part, the steel pipe forming of this secondary reducing adopts two cover necking dies to realize at present, that is, first a reducing is carried out in the end of steel pipe steel pipe on reducing die, then secondary reducing is carried out again in the position of reducing on another little reducing die.The method also exists not foot point: 1. the process employs two cover reducing dies, cost compare is high; 2. the method secondary reducing, complex process, working (machining) efficiency is lower; 3. second time reducing is reducing again on the position of first time reducing, and the surface of first time reducing of damaging in actual mechanical process is blind, thus reduces the quality of steel pipe.
Summary of the invention
Technical problem to be solved by this invention is: provide the steel pipe throat frock that a kind of good forming effect, working (machining) efficiency are high.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of steel pipe throat frock, comprises upper die component and lower mold assemblies;
Lower mold assemblies comprises base plate, base plate is provided with relatively two pieces of risers, base plate is provided with lower mount pad between two pieces of risers, lower mount pad is provided with two lower reducing devices, base plate is provided with material returned hole below two lower reducing devices, be movably equipped with material returned block in material returned hole, material returned block is provided with two lifting pins, and lower mount pad is provided with two jacking holes passed for lifting pin;
Lower reducing device comprises the die shoe be arranged on lower mount pad, up big and down small step through-hole is provided with in die shoe, extension bar is provided with at through hole inner bottom part in die shoe, locating core pipe is provided with above extension bar, die shoe is arranged with material returned pipe movable up and down in extension bar periphery, the jacking ring matched with lifting pin is arranged with bottom material returned pipe periphery, the step place of the inherent through hole of die shoe is provided with positioning seat, the through hole holding material returned pipe and pass is provided with in positioning seat, positioning seat is provided with spacer, spacer is provided with reducing die, reducing die is provided with fairlead, die shoe is provided with the gland compressing reducing die and fairlead,
Upper die component comprises top board, and top board lower surface is provided with two upper mounting blocks, and upper mounting blocks is provided with steel pipe pressure head.
As the preferred scheme of one, described riser is provided with lead, and on described top board, both sides are respectively equipped with guide pad, and guide pad is provided with the pilot hole matched with lead.
As the preferred scheme of one, lower mount pad is provided with pressure release through hole in the position corresponding to material returned pipe.
The invention has the beneficial effects as follows: owing to have employed all-in-one-piece reducing die, make tube forming better effects if.Owing to being provided with two lower reducing devices and steel pipe pressure head, make the working (machining) efficiency of this device higher.
Because riser is provided with lead, on described top board, both sides are respectively equipped with guide pad, and guide pad is provided with the pilot hole matched with lead, and when top board is pressed down, steel pipe pressure head can accurately be located.
