Description
Technical field
The invention belongs to electric wire production technical field, be specifically related to a kind of flexible adjustment device of traction wheel tensile force.
Background technology
In electric wire production process, extrusion moulding insulating barrier is one very important operation.The copper cash of copper core or the molded plastic foreskin of semi-finished product multiply, by the mould of plastic extruder, at its surface forming plastic insulating layer or outermost plastic layer, produces the semifinished or finished goods of electric wire.The copper cash of copper core or the molded plastic foreskin of half-finished multiply, before the mould passing through plastic extruder, must be strained, to guarantee forming quality.The used apparatus and method strained are establish a weight in the below of regulating wheel, utilize weight to drop tensioning voluntarily, and the method for this tensioning exists the defect that tensile force size cannot regulate and easily fall, and with potential safety hazard.
Chinese patent also has some about the patent of invention and the utility model patent that improve tensioning method and device, and these technical scheme structures are comparatively complicated, and it is convenient not to use, and manufacturing cost is higher, are difficult to promote the use of in reality is produced.
Summary of the invention
The flexible adjustment device of the traction wheel tensile force that the object of the present invention is to provide simple, reasonable in design, the easy to operate and tensile force of a kind of structure to regulate arbitrarily, it can solve used tensioning apparatus in background technology with various drawbacks, and the technical problem existed in state-of-the-art technology scheme.
For achieving the above object, the flexible adjustment device of traction wheel tensile force of the present invention, comprise installing rack, connecting plate one, traction wheel one, connecting plate two, traction wheel two, supporting screw, stage clip and nut, described connecting plate one is by a upper end being arranged on installing rack of shipping and reselling on another market, described traction wheel one is by two one end being arranged on connecting plate one of shipping and reselling on another market, and the other end of described connecting plate one is provided with U-lag; One end of described connecting plate two is by three centres being arranged on installing rack of shipping and reselling on another market, the other end of connecting plate two four is provided with traction wheel two by shipping and reselling on another market, the centre of connecting plate two is provided with positive six side's counterbores, supporting screw is provided with in described positive six side's counterbores, described supporting screw is provided with stage clip, the other end of supporting screw, through after U-lag, is connected with nut; The lower end of described installing rack is provided with backing plate, and described backing plate is provided with four screw holes.
In technique scheme, the degree of depth of described positive six side's counterbores is 2/3rds of supporting screw height of head.
After adopting technique scheme, rotating nut, can change the elastic force of stage clip, the change of stage clip elastic force, and the size of copper cash tensile force on traction wheel one and traction wheel two can be made to be changed, therefore operation is comparatively simple, and easy to adjust, reliability is high, steady quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the flexible adjustment device of traction wheel tensile force of the present invention.
Respectively be designated in accompanying drawing: 1, installing rack, 11, backing plate, 12, screw hole, 2, connecting plate one, 21, ship and resell on another market one, 22, U-lag, 3, traction wheel one, 31, ship and resell on another market two, 4, connecting plate two, 41, ship and resell on another market three, 42, positive six side's counterbores, 5, traction wheel two, 51, four are shipped and resell on another market, 6, supporting screw, 7, stage clip, 8, nut.
Embodiment
Be described further below in conjunction with the flexible adjustment device of accompanying drawing to traction wheel tensile force of the present invention:
As seen from Figure 1, the present invention it comprise installing rack 1, connecting plate 1, traction wheel 1, connecting plate 24, traction wheel 25, supporting screw 6, stage clip 7 and nut 8, described connecting plate 1 is by one 21 upper ends being arranged on installing rack 1 of shipping and reselling on another market, described traction wheel 1 is by 2 31 one end being arranged on connecting plate 1 of shipping and reselling on another market, and the other end of described connecting plate 1 is provided with U-lag 22; One end of described connecting plate 24 is by 3 41 centres being arranged on installing rack 1 of shipping and reselling on another market, the other end of connecting plate 244 51 is provided with traction wheel 25 by shipping and reselling on another market, the centre of connecting plate 24 is provided with positive six side's counterbores 42, supporting screw 6 is provided with in described positive six side's counterbores 42, described supporting screw 6 is provided with stage clip 7, the other end of supporting screw 6, through after U-lag 22, is connected with nut 8; The lower end of described installing rack 1 is provided with backing plate 11, and described backing plate 11 is provided with four screw holes 12.
Method of operation of the present invention is, first utilizes screw to be fixed on the ground by backing plate 11; The copper cash that will draw again or semi-finished product electric wire from traction wheel 1 around to traction wheel 25 place, according to the copper cash of traction or the tensioning degree of semi-finished product electric wire, adjust its tensile force, method of adjustment is: rotate clockwise nut 8, stage clip 7 on supporting screw 6 is by compacted, its elastic force increases, thus can increase the tensile force of copper cash or semi-finished product electric wire; When counter clockwise direction rotating nut 8, the distortion of stage clip 7 reduces, and its elastic force also reduces thereupon, thus the tensile force of copper cash on traction wheel 1 and traction wheel 25 or semi-finished product electric wire also can reduce.
In the present embodiment, described traction wheel 1 and traction wheel 25 are respectively provided with multiple winding slot, in extrusion moulding operation, keep the needs of suitable tensile force with the electric wire meeting different size.
In the present embodiment, the degree of depth of described positive six side's counterbores 42 is 2/3rds of supporting screw 6 height of head, and its objective is when rotating nut 8, supporting screw 6 does not rotate with nut 8, keeps the validity and reliability of adjustment tensile force.
In the present embodiment, for reducing use cost, simplified design structure, being connected and fixed of described connecting plate 1, traction wheel 1, connecting plate 24 and traction wheel 25 all adopts and can ship and resell on another market.
Structure of the present invention is simple, reasonable in design, easy to use; effectively can solve tensile force size adjustment inconvenience that existing tensioning apparatus brings and size can not regulate continuously; the technical problems such as the low and quality of production efficiency is unstable, can meet the needs of electric wire large-scale production.
