Abstract
The utility model discloses an adjustable rapid tube drawing machine which solves the problem of not easily drawn metal tubes with corrosion reduction existing in the prior art. The utility model comprises an oil cylinder, a spring, a pull rod, an elastic clamping claw, etc. The utility model is characterized in that a cone part arranged at the front end of the pull rod is connected with screw bolts which are connected with screw caps which are provided with stop openings. The utility model has the advantages of large range for drawing tubes, adjustable size of the elastic clamping claw within a large range, high disassembly efficiency and convenient operation. The utility model can be adapted to metal tubes with corrosion reduction preferably.
Description
Affiliated technical field
The utility model relates to a kind of dismounting machinery, relates to a kind of machinery of dismantling metal tube or rather.
Background technology
When the condenser of industries such as power plant, petrochemical industry, refrigeration, oil cooler, heater, heat exchanger etc. are changed metal tube, old metal tube need be extracted from the expanded joint tube sheet of container.The various drawbenches that use have changed the manual old-fashioned plumber's of the unloading skill of picking, cut a hole, dashing of traditional manpower at present, can finish tube drawing work efficient quick.But for being subjected to the metal tube of corrosion thinning in various degree, often be not easy to extract, will change bigger tube drawing head or change drawbench, cause the inconvenience in the work.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable quick drawbench, the size that can regulate the elasticity jaw more broadly, higher, the more convenient operation of removal efficiency.
The technical solution of the utility model is such: comprise oil cylinder, spring, pull bar, elasticity jaw etc., it is characterized in that: at the cone part connecting bolt of pull bar front end, connect the nut that has seam on bolt.
Described nut is provided with two.
The beneficial effects of the utility model are: 1, the tube drawing scope is bigger, more can adapt to the metal tube of the attenuate that is corroded, and does not need often to change the tube drawing head, and work is convenient.2, two nuts of She Zhiing are arranged side by side, can avoid moving owing to firmly producing, and the seam in the nut can avoid notched teeth unsettled, causes snaggletooth.When 3, the elasticity jaw is in contraction state, the tapering that the notched teeth band is certain, during spreading, notched teeth is parastate, and a plurality of notched teeths can be bitten metal tube simultaneously, parallel exerting oneself, comprehensively with strength.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1-pull bar, 2-cone, 3-elasticity jaw, 4-notched teeth, 5-oil cylinder, 6-piston, 7-spring, 8-hydraulic pump, 9-bolt, 10-seam, 11-nut.
The specific embodiment
As shown in drawings, the front end of pull bar 1 is a cone 2, and the rear portion is the cylinder of the piston 6 in the connection oil cylinder 5, and the other end of piston 6 connects spring 7.Elasticity jaw 3 is at least two arcuation housings that wait split, and the side face of front end is provided with the notched teeth 4 that order strengthens, and has cannelure between the notched teeth 4, is provided with jump ring in the groove; The rear end of elasticity jaw 3 is that round barrel shape is enclosed within on the cylinder of pull bar 1.Be provided with the hydraulic oil import of hydraulic pump 8 in the front of oil cylinder 5 inner carriers 6.
Cone 2 connecting bolts 9 connect two nuts 11 that have seam 10 on bolt, the maximum gauge of cone 2 is less than or equal to the size of seam 10.
During use, bolt 9 of the present utility model, nut 11 and cone 2 are inserted in the metal tube, inject hydraulic oil from hydraulic pump 8, piston 6 drives pull bar 1 and moves backward, is subjected to the crowded effect of rising of cone 2, the arcuation housing of elasticity jaw 3 separates gradually, spreading, it is big that the overall size of notched teeth 4 becomes, and parallel exerting oneself holds on to inner wall of metal tube, continue to inject hydraulic oil again and promote the piston motion, just can extract metal tube.Then, reclaim hydraulic oil, rely on the rebound effect of spring 7, piston 6 drives pull bar 1 reach, and elasticity jaw 3 is shunk, and then reuses.
Also can the boosting bar be set at an end of piston 6 band springs 7, with the elastic force of spring free 7 when not enough by the boosting bar, make piston 6 motions once with hand push; Perhaps establish the hydraulic oil import of a hydraulic pump 8 again, rely on the effect of hydraulic oil that piston 6 is travelled forward in the back of oil cylinder 5 inner carriers 6.
Become big metal tube for inside pipe wall corrosion thinning internal diameter, can nut 11 outward direction move, elasticity jaw 3 just can move bigger distance to the metal tube direction, makes notched teeth 4 separation, spreading bigger, catches the bigger metal tube of internal diameter.
Claims (2)
1, a kind of adjustable quick drawbench comprises oil cylinder, spring, pull bar, elasticity jaw etc., it is characterized in that: at cone (2) connecting bolt (9) of pull bar (1) front end, go up the nut (11) that connection has seam (10) at bolt (9).
2, adjustable quick drawbench as claimed in claim 1, it is characterized in that: described nut (11) is provided with two.
