A working front-table for the perforating machine of seamless steel tube is a multifunctional one, which has various exchangeable tube holders suitable for different specifications, a lock unit for locking the current tube holder, a roller-way lift mechanism, and a detachable raw tube pushing mechanism.

Description

The Working front desk of piercing mill of seamless steel tube

Technical field:

The invention belongs to the seamless steel pipe production technical field, be specifically related to a kind of Working front desk of piercing mill of seamless steel tube.

Background technology:

At present, its function of Working front desk of producing piercing mill of seamless steel tube both at home and abroad is single, promptly when solid billet is bored a hole, " V " shape hopper is installed on the Working front desk, solid billet is put into behind " V " shape hopper by push rod and is pushed blank to the punch perforation of once nipping, this Working front desk can only be used for little blank production, is applicable to few kind, production in enormous quantities.Produce the elevating mechanism that used Working front desk requires to have special blank pushing machine structure and roller-way group and roller-way group for hollow ingot secondary punch or hollow ingot expansion, the hopper and the hopper retaining mechanism of removable multiple shape and plurality of specifications also will be arranged.Above-mentioned two kinds of different Working front desks are respectively applied in the punch equipment of different production requirements, can not be equal to mutually, can not change, and can not be suitable for the needs of many kinds, plurality of specifications production.

Summary of the invention:

The object of the invention provides a kind of punch foreground of new construction, can satisfy the above-mentioned different needs of producing.

The present invention is achieved in that it comprises blank pushing machine structure, roller-way device and hopper, it is characterized in that being equipped with on the punch Working front desk removable, be applicable to different production requirements, multiple shape and the hopper of specification and the retaining mechanism that the hopper that replaces with is locked, the roller-lifting mechanism that can control the lifting of roller-way group is installed below Working front desk, the blank pushing machine structure that can remove is installed on the Working front desk table top.

Concrete structure is: on the Working front desk table top, the left and right sides is equipped with two can promote the hydraulic cylinder that the base substrate work seesaws, pushing away the base substrate front end is connected with the base head that pushes away that can promote the blank reach, the roller-way group is installed on the Working front desk table top, the roller-lifting mechanism that can make the lifting of roller-way group is installed on base, roller-lifting mechanism passes through fork by the spiral lift that is installed on the base, shift fork, connection rod set and quadric chain drive the lifting of roller-way group, drive fork and semilune dead bolt by the hydraulic cylinder that is installed on the base, the hopper that replaces with is vertically locked, and the voussoir that is installed on the base is laterally locked hopper.

Advantage of the present invention and good effect:

Multi-functional, multipurpose that the present invention has can satisfy different requirements of producing on an equipment, created condition for specification production how wide in variety, has saved equipment investment.

The specific embodiment:

Shown in Fig. 1～8, be installed on the base 8 two hydraulic cylinders 5 with push away base substrate 6 and be hinged by bearing pin, push away base substrate 6 front ends and push away base head 15 and be connected (seeing that Fig. 2 shows), spiral lift 1 is hinged by hydraulic cylinder 2 and fork 3 upper ends, fork 3 rotates around fixed axis 10, its lower end and connection rod set 7 are hinged, shift fork 4 lower ends and connection rod set 7 are hinged, the fixed rotating shaft 11 of a upper end and a quadric chain is hinged and (sees Fig. 1,2), four angle points of quadric chain are 11,12,13,14, wherein 11, the 12nd, fixed rotating shaft, 13, the 14th, mobile shaft can be made parallel mobile

mobile shaft

13,14 link together with the base of roller-way group 9 (sees Fig. 3,4,5).When spiral lift 1 starts, drive fork 3 and just can drive parallel motion by connection rod set 7 and shift fork 4 around fixed rotating shaft 10 swings by hydraulic cylinder 2, and drive roller-way group 9 liftings (seeing Fig. 1,3), hydraulic cylinder 19 is hinged with rocking bar 20 lower ends, the upper end of rocking bar 20 and semilune dead bolt 17 are connected by key, semilune dead bolt 17 just can vertically locked hopper 18 when hydraulic cylinder 19 promotes rocking bar 20 rotations, and the voussoir 21 that is installed in base 8 inboards is simultaneously also laterally locked (seeing Fig. 6,7) with hopper 18.When needs are bored a hole to solid billet, by making operation spiral lift 1 roller-way group 9 is reduced to extreme lower position, to be placed on the base 8 with the corresponding hopper 18 of solid billet specification,, operate hydraulic cylinder 5 again and push to the production of boring a hole in the punch forward after the hopper locking by operation hydraulic cylinder 19 by pushing away 6 pairs of solid billets of base substrate.Said process also goes for the hollow bloom of minor diameter, little length is carried out secondary punch.In the time need carrying out secondary punch or expansion production to the hollow bloom of major diameter, big length, to push away base substrate 6 and push away 15 dismountings of base head and withdraw, stroke by adjustable screw lift 1 is adjusted to roller-way group 9 height that makes the pipe center line consistent with rolling centerline, to lay again on the base 8 with the corresponding hopper 18 of hollow bloom again, operate hydraulic cylinder 19 subsequently hopper is locked, the transmission mechanism of restarting roller-way group 9 is sent to hollow bloom and carries out secondary punch or expansion in the punch.After pipe was successfully nipped, operation hydraulic cylinder 2 drivening rods 7 and quadric chain descended roller-way group 9, were not just damaged at rolling pipe with the roller of protecting the roller-way group.
