Description

Description: TECHNICAL FIELD The present invention relates to a profile drawing device for drawing a profile extruded from an extruder (extrusion press device). More specifically, the present invention relates to a profile drawing device of an extruder in which a puller is reciprocated above a runout table.

[Prior Art] Generally, a mold material extruded from an extruder is pulled by a puller of a mold material pulling device and pulled out onto a runout table while maintaining a straight state (for example, Japanese Patent Laid-Open No. 52-7316).
No. 3).

In JP-A-52-73163, a rail is provided above the runout table in parallel with the runout table, and the puller is guided by the rail to reciprocate. A clamp (chucking device) for grasping the mold material is provided on the puller so that it can be moved up and down. When the puller moves forward (grasp the mold material and move forward), the clamp is lowered to the required height and the puller is pushed out. The clamps are raised when returning toward the aircraft.

[Problems to be Solved by the Invention] In a conventional mold material towing device for an extruder in which the mold material towing device is installed above a runout table, a hydraulic device (a lifting power) for vertically moving a clamp provided on the puller is used. A cylinder) was mounted on the puller. Therefore, the puller becomes heavy, and the rails that support the puller and the equipment for running the puller become large,
The device configuration cost was high.

[Means for Solving the Problems] The profile drawing device of the extruder according to the present invention includes a pair of rails extending above the runout table and extending along the runout table, and is suspended on each rail. A puller which is guided by the rail and is capable of reciprocating in the run direction above the run-out table, and clamps for holding the mold material vertically provided, and the puller installed at both ends in the extending direction of the rail, And a clamp up-and-down moving device capable of changing the height of the clamp when the puller is located at both end positions.

[Operation] According to the mold material traction device of the extruder of the present invention, the mold material extruded from the extruder is gripped by the clamp of the puller, and is pulled by running the puller along the rail, and the runout table is provided. Pulled up.

When the puller reaches the end of the rail on the extruder side, the clamp is lowered by the clamp vertical movement device, and the mold material can be held. When the puller reaches the side of the rail opposite the extruder, the clamp releases the formerly held profile and the clamp is raised by the clamp up-and-down device. After that, the clamp is returned toward the extruder with the clamp being raised.

In the present invention, the clamp is moved up and down by the clamp vertical movement device installed outside the puller in this manner. Therefore, according to the present invention, since the clamp vertical movement device is not mounted on the puller, the weight of the puller can be reduced.
