Embodiment Construction
[0017] A structure of the present invention such as figure 1 As shown in the figure, the power device uses a DC motor to drive the main shaft gear through the reduction box, and the main shaft gear engages the chain fixed on the rail to achieve a constant elliptical motion trajectory. The clamp blocks are connected to the jaws by means of the universal dovetail grooves on the jaws, the jaws are connected to one side of the rotation shaft, the rotation shaft is movably connected to the running gear, and the running gear is fixed on the running gear. The clamping device is driven by hydraulic pressure, and the jaws, jaws and rotation axis of the clamping device can be rotated by hydraulic drive. Such as image 3 As shown, the jaws and the jaws are fan-shaped eccentric wheel structures, and one end of the jaws is embedded in the jaws or the jaws are arranged on the outer edge of the jaws of the eccentric wheel. The clamp block is preferably a high-temperature-resistant block th...

The invention discloses a special magnesium alloy extruding and towing machine comprising a power device and an elliptic walking device used for towing the magnesium alloy section to move. The walking device is driven by the power device. The speed of the walking device is infinitely adjustable. The rotating speed of the special magnesium alloy extruding and towing machine is controlled to be more than or equal to the magnesium alloy section exit speed according to the real-time response of the magnesium alloy section exit speed. A magnesium alloy clamping device is arranged on the walking device. The special magnesium alloy extruding and towing machine has reasonable structure and can effectively avoid the defects that the pipe section which has unstable section size and poor straightness, particularly the high-strength aluminum alloy and the high-strength magnesium alloy which are difficult to extrude, are difficult to extrude and tow due to the vibration of the machine, the dead weigh of the pipe section, the high-strength aluminum alloy and the high-strength magnesium alloy, the change of speed and temperature under the condition of the extrusion breakthrough pressure and the like. The invention adopts the novel grasping, stretching and towing principle, keeps a towing mechanism having constant stretching force in 3 meters away from the exist end and solves the problem on the production and the towing of the high-strength aluminum alloy and the high-strength magnesium alloy which are difficult to extrude.
Description
technical field [0001] The invention belongs to the field of magnesium alloy preparation, and in particular relates to a tractor device specially used in magnesium alloy extruded profiles and matched with an extruder. Background technique [0002] Commonly used servo motor extrusion tractors, due to tractor control and action principles, cannot guarantee a constant traction force within 3 meters near the exit, so the pipe profile is often due to machine vibration, product weight, speed and temperature under extrusion pressure conditions Changes and other factors, the cross-sectional size is unstable, and the straightness is not good. Especially high-strength aluminum alloys and magnesium alloys that are difficult to extrude. Contents of the invention [0003] The purpose of the present invention is to solve the production traction problem of high-strength aluminum alloy and magnesium alloy profiles that are difficult to extrude and provide a special extrusion tractor for ...
