The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present invention and operation principle.
As shown in drawings, the present invention's conical seamless steel-tube making machine, comprise from back to front and go up the support of arranging (1) at support (6) successively, support plate (5), back push pedal (9), preceding push pedal (13), front supporting plate (18), hydraulic jack (2) is fixed on support (1) and the support plate (5), back push pedal (9) is fixed on the front end of the plunger rod (7) on the hydraulic jack (2), push rod (11) one ends are fixed in the back push pedal (9), the other end is fixed in the preceding push pedal (13), forefront at described support (6) has core print mould rack (25), pull bar (17) rear end is connected on the support plate (5), connecting rod (214) on front end and the mould (21) links together, mould is made up of the conical section (213) and the anterior straight length (212) at rear portion, the rear end of mould is installed on the core print mould rack (25), there is Medium frequency induction coil device (19) the mould outside at rear portion, and there is another induction coil device (23) anterior mould outside.
Described mould (21) is made by nichrome heat resisting steel.
As Fig. 3, Fig. 4, shown in Figure 5, on described mould (21), conical section at rear portion (213) and anterior straight length (212) are installed in connecting rod (214) outside, and connecting rod links together by screw thread and pull bar.The conical section mould is made of more piece, and the head of a joint mould by taper of front is inserted in the conical socket of a joint mould of back.On the two adjacent joint moulds pin rod (215) and the pin-and-hole corresponding with pin rod can be arranged respectively, pin rod injects the connection location of realizing two joint moulds in the pin-and-hole.Obviously, on mould, the external diameter that respectively saves mould of close core print mould rack (25) is greater than the external diameter that respectively saves mould of its back.Fixed axis on the straight length mould (211) can be directly installed on the core print mould rack, also can be installed on the core print mould rack by being plugged in the connecting axle (24) on the core print mould rack.
At forward and backward push pedal leading flank push pedal door (15) and another push pedal door (10) are arranged respectively, two push pedal doors link together with hydraulic jack (14) and another hydraulic jack (8) above it respectively.The trailing flank of support plate (5) has gate (4) and the gate hydraulic jack (3) above it to link together.Pull bar (17) rear end is connected on the support plate (5) by gate (4).Gate, push pedal door are installed in respectively on the centre position of support plate, back push pedal and preceding push pedal.The concrete structure of push pedal door, gate advances gate or push pedal door on the tuber identical with operating principle and existing a series of two steps of hydraulic pressure, is prior art, no longer describes in detail.Supporting with it hydraulic power unit, medium frequency induction power supply device and electrical control cabinet etc. are arranged when obviously, the present invention uses.
Advance on the tubers equally with existing two steps of a series of hydraulic pressure, the roller of forward and backward push pedal below it is installed on the guide rail (12) on the support.
The basic frame for movement of the present invention's conical seamless steel-tube making machine advances tuber similar with course of action and existing a series of two steps of hydraulic pressure.During use, open push pedal door in push pedal and the preceding push pedal of back, make seamless steel pipe to be processed (16) pass back push pedal and preceding push pedal from the outside of pull bar by the hydraulic jack of push pedal door.Close the rear end that the push pedal door in the push pedal of back makes it to withstand seamless steel pipe to be processed, clamp the rear end of pull bar (17) fixing by gate.After this, primer fluid compressing cylinder (2), plunger rod (7) promote the back push pedal and move forward, and also move forward thereby make the back push pedal promote seamless steel pipe.One section of seamless steel pipe by the Medium frequency induction coil on the Frequency Induction Heating coil device and a section die at rear portion, and seamless steel pipe is heated the back and finishes the preliminary deformation that seamless steel pipe becomes conical pipe by mould.When after after push pedal shifts the position onto, the push pedal door in the push pedal of back is opened, back push pedal and preceding push pedal while retreat under the drive of the plunger rod on the hydraulic jack and put in place.Push pedal door before closing in the push pedal, just in time withstand the rear end of processed seamless steel pipe, when the plunger rod on the hydraulic jack promotes forward once more, can drive seamless steel pipe carries out the second time forward and moves, another of seamless steel pipe section another section by Frequency Induction Heating coil device and mould is finished the final distortion of whole seamless steel pipe.In the tubulation process, can adopt and respectively to save the mode that mould is put in batches on the mould.
Between described Medium frequency induction coil device (19), another induction coil device (23), the 3rd Medium frequency induction coil device can also be arranged.The Medium frequency induction coil device is made up of Medium frequency induction coil and the coaster (20) below it.The Medium frequency induction coil is realized the heating to seamless steel pipe.Tackle arrangement (22) can be arranged between the Medium frequency induction coil device, roller is arranged on the tackle arrangement with support mould and seamless steel pipe.
