The front end of the movable wedge is connected with an electro-hydraulic push rod by a sliding plate, and the back end of the movable wedge is provided with a clamp mouth for playing a role of clamping pipes. The utility model has the advantage of flexible and convenient operation. In order to increase the working efficiency of the cold-drawing machine, the utility model provides new equipment, saves hours of wok and the pipes and plays a significant effect in the cycle operation of the cold-drawing machine.
Description
Technical field
The utility model relates to a kind of tubing cold-drawn process equipment, especially a kind of drawbench drawing dolly.
Background technology
The drawbench that now is used for processing metal tubing, usually adopt reciprocating motion at the drawing dolly of same horizontal plane setting to realize and send to the stretching of tubing, realize clamping in the reciprocating folding of controlling clamp on the drawing dolly simultaneously to tubing, in the prior art, clamp is a mechanical type, easy landing when no external force is assisted clamping tubing, drawbench is in the tubing process, the clamp of drawing dolly need be done high-frequency clamping, opens, holding action, the back mechanical type clamp sensitivity that works long hours descends, and damages easily; The traction of drawing dolly generally adopts roller chain to apply active force in addition, and there is the instantaneous velocity fluctuation in chain drive, causes drawing speed inhomogeneous easily, influenced the surface quality of tubing, and roller chain weight is bigger, operate dumb, especially for length longer pipe material.
The utility model content
The purpose of this utility model is to propose a kind of drawbench drawing dolly that can carry out at the uniform velocity drawing to length longer pipe material for the above-mentioned shortcoming that solves prior art.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of drawbench drawing dolly, comprise wheel and vehicle frame, its improvements are, the both sides, rear end of described vehicle frame are provided with decides voussoir, decide to be provided with between voussoir shape and decide the moving voussoir that voussoir matches for described two, describedly decide voussoir and be connected with moving wedge slides, the front end of described moving voussoir is connected with Electrohydraulic push rod by slide plate, and the rear end of described moving voussoir has been provided with the tong chops of clamping tubing effect.
The purpose of this utility model can also further realize by following technology solution:
Aforesaid a kind of drawbench drawing dolly, wherein said moving voussoir is made up of two plates, and described two relative sides of plate are provided with groove, are provided with tong chops in the described groove, and described two tong chopses form the clamp mouth relatively.
Aforesaid a kind of drawbench drawing dolly, the front end of wherein said plate is provided with horizontal slotted hole, and described horizontal slotted hole is connected with slide plate by bearing pin.
Aforesaid a kind of drawbench drawing dolly, the front end of wherein said drawing dolly is provided with the pulley that is connected with the coarse-wire rope of draw-gear, and the rear end of described drawing dolly is connected with the seizing wire of draw-gear.
Aforesaid a kind of drawbench drawing dolly, wherein said Electrohydraulic push rod is connected with the slip groove that is used for continued power.
The utility model has the advantages that the tong chops that adopts Electrohydraulic push rod to drive carries out initial clamping to tubing before drawing begins, tubing comes off when having prevented not only that drawing is initial, and the folding of jaw still has high sensitivity when reciprocating frequency is higher, action is quick; Adopt steel wire cable transmitting tractive power drawing pipes stably, thus the uniform and stable surface quality of improving tubing of drawing speed.In a word, drawbench drawing dolly flexible and convenient operation of the present utility model for the operating efficiency that improves drawbench provides a kind of new equipment, has been saved man-hour, has saved the pipe material, in the cycle operation of drawbench, plays remarkable result.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a drawbench drawing vehicle structure schematic diagram of the present utility model.
The specific embodiment
Embodiment one
The structure of present embodiment as shown in Figure 1, a kind of drawbench drawing dolly, comprise wheel 1 and vehicle frame 2, the both sides, rear end of vehicle frame 1 are provided with decides voussoir 3, deciding 3 of voussoirs for two is provided with shape and decides the moving voussoir 4 that voussoir 3 matches, deciding voussoir 3 is slidingly connected with the dovetail groove form on faying face with moving voussoir 4, the front end of moving voussoir 4 is connected with the piston rod of Electrohydraulic push rod 6 by slide plate 5, the cylinder body of Electrohydraulic push rod 6 is fixedly mounted on the drawing dolly, slide plate 5 can move along slideway 51, the rear end of moving voussoir 4 has been provided with the tong chops 8 of clamping tubing 7 effects, moving voussoir 4 is made up of plate 41 and plate 42 butt joints, plate 41 is provided with groove with plate 42 relative sides, be equipped with tong chops 8 in the groove, two tong chopses 8 form the clamp mouth relatively, and the front end of plate 41 and plate 42 is equipped with horizontal slotted hole, and laterally slotted hole is connected with slide plate 5 by bearing pin.The front end of drawing dolly is provided with the pulley 9 that is connected with the coarse-wire rope of draw-gear, the rear end of drawing dolly is connected with the seizing wire of draw-gear, draw-gear is given coarse-wire rope and seizing wire counter traction, the proal while of drawing dolly under the effect of tractive force, also tubing 7 is carried out drawing.Electrohydraulic push rod 6 is connected with the slip groove in addition, and the slip groove is connected with circuit can be to Electrohydraulic push rod 6 continued powers, can guarantee in whole drawing process the continual and steady active chucking power to tubing 7, and the pine folder freely, can not produce and pull phenomenon.
When the drawing dolly carries out clamping to the head end of tubing 7, Electrohydraulic push rod 6 drives slide plate 5 and advances to tong chops 8 along slideway 51, slide plate 5 drives bearing pin and is laterally moving in the slotted hole, thereby the tong chops 8 that drives on plate 41 and the plate 42 tightens up, tong chops 8 produces the head end that enough radial pressures clamp tubing 7 thus, sawtooth on the holder arms is bitten tubing 7 head end outer walls, makes that the clamping of 8 pairs of tubing 7 of tong chops is more firm.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the protection domain of the utility model requirement.
