The traction machine is used for traction when the aluminum profile is extruded, and is provided with a clamping mechanism for clamping the aluminum profile, the clamping mechanism generally comprises a supporting plate and a pressing plate, and the pressing plate moves downwards to clamp the aluminum profile under the combined action of the pressing plate and the supporting plate so as to drive the aluminum profile to move.
Generally, the height of the supporting plate is the same as that of the supporting roller on the production line, when the tractor moves, the supporting roller can prevent the tractor from moving, therefore, the support of the supporting roller can normally rotate or stretch out and draw back, and when the tractor clamping mechanism passes through, the supporting roller descends in a rotating or shrinking mode, so that the tractor can smoothly pass through. The number of the carrier rollers on the production line is large, each carrier roller can move, so that the cost of the production line is increased, the reliability of the production line is reduced, and the maintenance cost is increased.
Secondly, when the clamping structure clamps the aluminum profile, the supporting plate is lower than the bottom of the aluminum profile, so that a group of supporting rollers capable of being lifted are arranged at the clamping position close to the extruding opening in the existing production line, the aluminum profile is supported high before the clamping structure clamps, and the lower supporting plate is ensured to be inserted from the bottom of the aluminum profile. But the carrier roller also lifts the height of aluminium alloy simultaneously, and the aluminium alloy that passes through here has become the wave from the straight line, reduces the production quality of aluminium alloy.
In addition, the clamping mechanism gradually increases the pressure during clamping, so that the initial clamping pressure is smaller, and the aluminum profile cannot be clamped. In order to avoid the relative movement between the clamping mechanism and the aluminium profile, it is necessary to wait until the movement speed of the tractor increases to the same speed as the movement speed of the aluminium profile before the clamping starts. This speed is generally determined by the extrusion speed, which is not stable, and it is generally not guaranteed that the speed of the tractor is the same as the movement speed of the aluminium profile, increasing the risk of the clamping structure and the aluminium profile moving relatively during clamping.
