Abstract

The utility model relates to a wire-rope cool tube drawing bench, which comprises an auxiliary guideway. The auxiliary guideway is supported by a wound roll base arranged at the front end, a die stand at the tail end, and a plurality of C-shaped frame arranged in the middle. The guideway is provided with a plyer and also comprises a wire-rope transmission mechanism and a motor drive mechanism of a drawing plyer. The tube drawing bench is characterized in that the plyer is drawn to run by the adoption of transmitting force of a wire rope so that drawing process is more stable. In addition, the winding of the wire rope adopts an overlapping-type winding mode so that the volume of a wound roll can be decreased; moreover, the wire rope is connected with the plyer by a balance wheel so as to ensure the balance of double-pulling force.

Description

A kind of Wire rope type cold tube drawing bench

The utility model is a kind of cold drawing tube machine with wire rope transfers power.

In prior art, a kind of chain type cold drawing tube machine of domestic public use mainly by guide rail, establish the preceding support of guide rail front end and be located at the guide rail tail end the drawing-die seat, be located at a plurality of C shape seats in the middle of the guide rail, be located at plyer on the guide rail and the chain drive and the motor-driven mechanism of traction plyer constitutes.This chain type cold drawing tube machine transmits power with chain and draws plyer and move on guide rail, thereby finishes the process of tube plug drawing mill of pipe.Because the existence of chain link plate, it exists periodic intermittently to impact in transmission, thereby in the pipe draw oscillation phenomenon is arranged.This oscillation phenomenon can worsen the production tube surface quality, and particularly when high speed draw light-wall pipe, this oscillation phenomenon can increase, and also can cause tube brakes.Therefore, this chain type cold drawing tube machine not too is suitable for draw light-wall pipe and tubule.

The purpose of this utility model is in order to overcome existing chain type cold drawing tube machine shortcoming stably inadequately in process of tube plug drawing mill, to provide a kind of Wire rope type cold tube drawing bench, to reach the steady requirement of drawing.

For achieving the above object, solution of the present utility model is as follows: a kind of Wire rope type cold tube drawing bench, it comprises one pair of guide rail, this pair guide rail is supported with being located at the drawing-die seat of its tail end and being located at its middle a plurality of C shape framves by the preceding support that is located at its front end, on described guide rail, be provided with plyer, it also comprises transmission mechanism and the driving mechanism that draws plyer, its improvement is: the transmission mechanism of described traction plyer is the steel wire rope type transmission mechanism, and it is by reduction box, cable drum before being installed on the support, a traction coarse-wire rope and two seizing wires of pulling back are formed; The rotating shaft of described cable drum and the output shaft of reduction box link; Described cable drum has slightly, the seizing wire separate slot; Described coarse-wire rope level is walked around the equalizer pulley of plyer head, is connected in pairs in the coarse-wire rope separate slot of cable drum again; One end of described two seizing wires is connected in the seizing wire separate slot of cable drum, and after its other end was walked around leading block on the drawing-die seat, the afterbody with plyer linked again; The driving mechanism of described traction plyer is used to control the motor of paying of pulling back by a main motor that is used to control drawing and one and forms, and their output shaft links by belt gear and gearbox primary shaft respectively.

By above-mentioned solution as can be seen, the utility model adopts wire rope transfers power and draws the plyer operation, thereby has overcome the oscillation phenomenon in the process of tube plug drawing mill.Simultaneously, the eclipsed form canoe is adopted in the winding of the steel wire rope of this drawbench, can reduce the reel volume greatly; Moreover steel wire rope is connected by stabilizer with plyer, has guaranteed the equilibrium of two pulling force amounts.Therefore, the utility model is not only the oscillation phenomenon that overcomes in the process of tube plug drawing mill, but also have that reasonable in design, volume are little, in light weight, the advantage of reliable operation etc.

Describe structure of the present utility model and operation principle in detail according to embodiment below.

Fig. 5, C shape holder structure schematic diagram (the A-A face topology view of Fig. 1).

Referring to Fig. 1,2, this drawbench is provided with one pair of guide rail 1, is provided with on reel pedestal 2 and the drawing-die seat 3 at the two ends of guide rail, is provided with a plurality of spaced C shape seats 4 in the middle of the guide rail; On guide rail 1, be provided with reciprocating plyer 5; The transmission mechanism of plyer is made of reduction box 6, cable drum 7, coarse-wire rope 8 and seizing wire 9; Wherein coarse-wire rope 8 levels are walked around the stabilizer 5.1 (as shown in Figure 3) of dolly 5 front ends, and then connect firmly on cable drum 7; One end and the reel 7 of described seizing wire 9 connect firmly, and after the other end was vertically walked around leading block 10 on the drawing-die seat, the tail end with plyer 5 joined again; The rotating shaft and the reduction gearbox output shaft of described cable drum 7 link; The driving mechanism of plyer is by main motor 11 and pay a motor 12 and form, and the power shaft by belt gear and reduction box links respectively.When starting main motor 11, it drives cable drum 7 by reduction box and rotates counterclockwise, the reel one side with coarse-wire rope roll, one side decontrols seizing wire, then draw pipe drawing dolly 5 and move forward; When running to terminal point, stop main motor, then dolly 5 stops.When motor 12 was paid in startup, it drove reel 7 by reduction box and clockwise rotates, and then coarse-wire rope and finer wire counter motion makes dolly 5 return drawing-die seat place rapidly.Forward and backward destination county at guide rail also is provided with travel switch, reaches home when running into travel switch when dolly, then automatically shuts down main or pays motor, and dolly is stopped automatically.Sequence number 19 is a lubrication box among the figure.

Referring to Fig. 3, on described plyer 5, be provided with a pneumatic tongs 13, the termination that is used to clamp pipe 14.Pipe 14 is before drawing, and its termination will be carried out tup and handled, and makes it can extend through the nib of drawing mould 15 and is clamped by pneumatic tongs 13.

Referring to Fig. 4, on described cable drum 7, be located at the steel wire rope separate slot, the middle part is a pair of separate slot of coarse-wire rope, two ends are a pair of separate slots of seizing wire.The two ends of described coarse-wire rope 8 connect firmly respectively in its separate slot inboard, adjust the width of stabilizer, can make the winding direction of this steel wire rope and trolley travelling direction be a little sharp angle, and α are equal to or less than 1.4 °; In like manner, an end of two seizing wires connects firmly the outside at its separate slot respectively, adjusts the width of seizing wire separate slot then, makes the winding direction of seizing wire and dolly direction of advance also present little sharp angle.Like this, steel wire rope just can form neat lamination and twine, thereby the reel volume is dwindled greatly.Referring to Fig. 1, even more ideal again for the motion that makes steel wire rope, on steel wire rope, be provided with balance weight mechanism 16, this balance weight mechanism can play the pretension effect to steel wire rope, simultaneously, can also remedy the part that the steel wire rope folding and unfolding does not wait.

Referring to Fig. 5, on described C shape frame, also be provided with a pneumatic gripper clamp 17, this pneumatic gripper clamp is controlled by travel switch, when dolly by the time, pneumatic gripper clamp action and folder buttresses pipe has prevented the pipe deformation that the pipe preshoot caused when drawing finished.When dolly 5 stopped, pneumatic gripper clamp also cut off the power supply simultaneously and discharges pipe, and the pipe that then draws slides in the hopper 18 under the inclined-plane of C shape seat.
