A kind of novel tungsten electrode wire drawing dolly
Technical field
The utility model relates to a kind of wire-drawing frame, is specially a kind of novel tungsten electrode wire drawing dolly.
Background technology
Need to carry out wire-drawing operation in the processing tungsten electrode process, be about to tungsten type piece and pull into uniform filament shape.The method that this link adopts at present is generally: adopt the jaw clamp-type piece of wire drawing dolly front end, the wire drawing dolly moves in orbit backward at the following of chain drive, and tungsten type piece is pulled into even filament shape.Because the jaw of wire drawing dolly front end once can only a tungsten type of clamping piece, wire drawing efficient is extremely low, owing to need supply heat and power always in drawing process, adopts present wire drawing dolly to cause a large amount of wastings of resources simultaneously.
The utility model content
Conventional art efficient is low in order to solve, the deficiency of waste resource, and it is a kind of rational in infrastructure that the utility model provides, and can once two type pieces be carried out the novel tungsten electrode wire drawing dolly of wire-drawing operation.
For realizing above-mentioned technical purpose, the utility model is achieved through the following technical solutions: a kind of novel tungsten electrode wire drawing dolly, comprise a chassis, the below, chassis is provided with guide wheel, it is characterized in that chassis front end central authorities are provided with a regular jaw, the regular jaw both sides are respectively equipped with a moving jaw, moving jaw is fixed on the tong arm, two tong arms are all to clamping face one lateral buckling of corresponding moving jaw, two tong arms are cross-linked in the bending place, and be fixed on the chassis by fixed axis at infall, two tong arm tail ends axle respectively connect a torque arm, and two torque arm other ends are hinged, and be fixed on the slide block by fixed axis, the chassis is provided with chute, and slide block is embedded in the chute, and both form the moving sets along y direction.
Above-mentioned novel tungsten electrode wire drawing dolly integral body in the horizontal direction the cross section along chassis axis symmetry.
In the actual production process, slide block is connected with the chain that power is provided, chain drives slide block and moves backward, gearing by torque arm, tong arm, two moving jaws move to regular jaw, type piece of clamping respectively between two moving jaws and the regular jaw under the drive of power chain, is realized disposablely following the type piece to finish wire-drawing operation with two.
The utility model is compared with conventional art, has following beneficial effect: simple in structure, practical, can be once with two tungsten electrode silks of wire-drawing shape, compare with former technology, about wire drawing efficient doubles, effectively avoided the waste of heat, power in system's operation process.

Fig. 2 is plan structure figure of the present utility model.
Among the figure, 1, moving jaw, 2, regular jaw, 3, fixed axis, 4, tong arm, 5, torque arm, 6, slide block, 7, the chassis, 8, guide wheel, 9 chutes.
The specific embodiment
Referring to accompanying drawing 1,2,7 bottoms, chassis are provided with 4 guide wheels 8, and chassis 7 front ends are provided with a regular jaw 2, and both are fixedly connected; The both sides of regular jaw 2 are respectively equipped with moving jaw 1.1 and 1.2, moving jaw 1.1 and 1.2 rear portions are respectively equipped with tong arm 4.1 and 4.2, tong arm 4.1 with 4.2 at clamping face one lateral buckling of front middle part to corresponding moving jaw, tong arm 4.1 and 4.2 is hinged and be fixed on the chassis 7 by fixed axis 3.1 in the bending place; Tong arm 4.1 and 4.2 rear ends axle respectively are connected with torque arm 5.1,5.2, torque arm 5.1,5.2 other ends are articulated and connected and are fixed on the slide block 6 by a fixed axis 3.2, slide block 6 is embedded in the chute 9 at 7 rear portions, chassis, slide block 6 can move forward and backward in chute 9, the power chain that slide block 6 connects on the wire drawing machine.
Said apparatus in the horizontal direction the cross section along the chassis 7 axis symmetries.
