Quality.With the development of industry, requirement of the user to aluminum products is also more harsh, and either surface quality or performance are all wished
Prestige can have more preferable lifting, and so structure and performance for hauling machine it is also proposed higher requirement;And existing traction machine
Class is various, but the following defect of generally existing:
(1) hauling machine is improved using chain and steel wire rope needs strainer in tractive force, system, haulage gear is in height
When speed operation can because tension force change and fluctuation of service, and section bar is in clamped condition, and this when can be in type
Material surface leaves cut, causes the increase of defective products, and the control accuracy of positioning and tractive force all has unstability, nothing
The quality of method strict guarantee product, simultaneously because chain and the limitation of steel wire rope intensity itself and use condition, it is impossible to meet big ton
The production requirement of the extruder of position;
(2) two hauling machines are in same moving on rails, and each circulation is required for joining section bar, and handshaking can be produced
Extra waste material, increases production cost;Either in handshaking, or working as one leads in machine high speed motions, all holds
Another hauling machine vibrations are easily caused, so that ripple occurs in Surface of profile, occur quality problems;And flexibility is bad, when one
Platform hauling machine breaks down, and can cause whole production line stop;
(3) portion's work by human assistance, it is necessary to drawn to quenching unit rear portion after quenching for hauling machine, then hauling machine
It could clamp, start traction, such waste of manpower, automaticity is poor, particularly with the extruded threads of large-tonnage, artificial operation is very
Waste time and energy;
(4) clamp of existing hauling machine is the clamp of piece-shape type finger-type or other structures, and method of clamping is all needed by oil
Cylinder or cylinder driving locking, so as to realize that section bar is clamped, this mode easily causes section bar deformation, produces many waste materials, and simultaneously
It is not suitable for the porous fashion of extrusion of a mould.
