Technical Field

The invention belongs to the technical field of forging and pressing metallurgical equipment, and particularly relates to a double-driving device and a driving method for an aluminum profile extrusion tractor, which are suitable for driving the aluminum profile extrusion tractor.

Background

Traction is one of very important links in the extrusion production process of the aluminum profile. When the aluminum profile is extruded, the friction between the aluminum ingot blank and the extrusion tool and die (extrusion cylinder, die, extrusion pad, etc.) causes the uneven flow velocity along the cross section direction in the extrusion process of the aluminum ingot blank. The aluminum profile is drawn by the tractor, so that the non-uniform flow speed can be eliminated, the flow of the product along the cross section is uniform, and the forming of metal in a welding chamber in the die is facilitated.

The existing traction machine is driven by a motor reducer in a driving mode, so that the aluminum profile is pulled to advance. The driving mode is suitable for traction of normal extrusion production, but has the problems that traction force of a traction machine cannot pull the aluminum profile out of a die opening smoothly when the aluminum profile is demolded after extrusion is finished, and demolding is often finished by using an auxiliary tool manually. Because the tractor normally works for a long time and only needs larger output torque when the extrusion is finished and the demoulding is finished, if a motor reducer with larger power is adopted, on one hand, the manufacturing cost is higher, and the burden is increased; on the other hand, when the motor works normally, the motor is in a low-power state for a long time, so that the motor and a control system are easy to generate heat seriously, and the service life is influenced.
