Abstract

PURPOSE:To reduce the weight of a puller by driving to run the puller by a running driving device of the outside, and also, executing the up-and-down motion of the clamp of the puller by an up-and-down motion device of the outside so as to load no clamp and down device on the puller. CONSTITUTION:A section 34 extruded from an extruding machine 10 is gripped by clamps 36b, 36a of pullers 24, 26, and also, pulled by running the pullers 24, 26 along a rail 16, and pulled out onto a run-out table 12. When these pullers 24, 26 reach the end part of the extruding machine side of the rail 16, the clamp 36 is allowed to descend by clamp up-and-down motion devices 40, 42, and can grip the section 34. When the pullers 24, 26 reach the opposite side of the extruding machine 10 of the rails 16, 18, the clamp 36 releases the section 34, and the clamp 36 is allowed to ascend by the clamp up-and-down motion devices 40, 42. Thereafter, in a state that this clamp 36 is allowed to ascend upward, the clamp 36 is returned toward the extruding machine side.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a profile pulling device for pulling a profile extruded from an extruder (extrusion press device). Specifically, the present invention relates to a profile pulling device for an extruder in which a puller is reciprocated above a runout table.

[Prior Art] A shape material extruded from an extruder is generally pulled by a puller of a shape material pulling device and pulled out onto a runout table while maintaining a straight state (for example, Japanese Patent Laid-Open No. 52-7
No. 3163).

In JP-A No. 52-73163, a rail is provided above the run-out table in parallel with the run-out table,
A puller is guided by the rail and reciprocated. The puller is equipped with a clamp (chucking device) that can move up and down to grip the shape material, and when the puller moves forward (grabs the shape material and moves forward), the clamp is lowered to the required height.
When the puller returns toward the extruder, the clamp is kept raised.

[Problems to be Solved by the Invention] In the conventional extruder shape pulling device in which the shape pulling device is installed above the runout table, a hydraulic device (elevating power cylinder) was mounted on the puller. Therefore, the puller becomes heavy, and the rails and pullers that support the puller.

The equipment required to run the machine was large-scale, and the equipment configuration costs were high.

[Means for Solving the Problems] A profile pulling device for an extruder of the present invention includes a pair of rails extending above the runout table and along the runout table, and each rail is suspended from the pair of rails. , a puller that can be guided by the rail and reciprocated in the run direction above the run-out table, and is provided with a clamp for gripping the profile material so as to be movable up and down, and is installed at both ends of the rail in the extending direction, The apparatus further includes a clamp vertical movement device that can change the height of the clamp when the puller is located at the both end positions.

[Function] According to the extruder profile pulling device of the present invention, the profile extruded from the extruder is gripped by the clamp of the puller, and is pulled by the puller running along the rail, so that the profile is pulled out of the runout. pulled out onto the table.

When this puller reaches the end of the rail on the extruder side, the clamp is lowered by the clamp vertical movement device and can grip the profile. When the puller reaches the side of the rail opposite to the extruder, the clamp releases the section it was gripping and the clamp is raised by the clamp lifting device. Thereafter, with the clamp raised upward, the clamp is returned toward the extruder.

In the present invention, the clamp is thus raised and lowered by the clamp vertical movement device installed outside the puller. Therefore, according to the present invention, since the puller is not equipped with a clamp vertical movement device, the weight of the puller can be reduced.
[Examples] Examples will be described below with reference to the drawings.

1 to 3 are schematic diagrams of the configuration and operation of the embodiment device. Reference numeral 10 denotes an extruder, and a runout table 12 is installed at the front portion of the extruder in the extrusion direction.

An upper rail 16 and a lower rail 18 are provided above the runout table 12.

These rails 16 and 18 are installed in pairs in the width direction of the runout table 12. .

The upper rail 16 and the lower rail 18 are fixed to the beam 20.

A puller 24.26 is installed to be moved along the rail 16.18. The puller 24 is the extruder 10
Rail 16 on the left side when facing the opposite side (Rail 1 to be described later)
6b), the puller 26 is suspended from the right rail 16 (rail 16a, which will be described later), and the puller 26 is suspended from the right rail 16 (rail 16a, which will be described later),
A steady rest is provided by b118a).

These pullers 24.26 are each equipped with wheels and are capable of traveling along the rail I6.18, but are not self-propelled and are not equipped with a traveling drive device.

In order to run the pullers 24, 26, the beam 20
A drive wheel 28 connected to a drive device is installed on the opposite side of the extruder 10, and a driven wheel 30 is pivotally connected to the extruder 10. A wire lobe (driving force transmitting member) 32 is stretched between these driving wheels 28, 30, and the ends of the wire lobe 32 are connected to pullers 24, 26.

The drive wheel 28, the driven wheel 30, and the wire lobes 32 are provided in pairs in the width direction of the runout table 12, one wire lobe 32 being connected to the puller 24, and the other wire lobe 32 being connected to the puller 26. (The moving shaft 28.30 and the wire lobe 32 are not shown in FIG. 2.3.) The puller 24.26 is provided with a clamp 36 for gripping the profile 34 extruded from the extruder 10.

Both the clamp 36 (36b) of the puller 24 and the clamp 36 (36a) of the puller 26 can pass through the same position in the width direction of the runout table 12.

In the puller 24, 26, a clamp 36 is provided to be movable up and down, and a rod 38 connected to the clamp 36 extends upward.

Devices 40, 42 for moving the clamps 36 up and down are provided at both longitudinal ends of the beam 20, respectively.

This clamp vertical movement device 40.42 is a hydraulic cylinder 4
4.46 and a chuck 48.50 provided at the tip of the piston rod, and the chuck 48.50 is capable of gripping a grip 52 at the upper end of the rod 38. These clamp vertical movement devices 40 and 42 are also provided in pairs in each width direction of the runout table 12.

In the extruder profile pulling device configured in this way,
When extruding a shape material, as shown in FIGS. 1 to 3, when the clamp 36 of one puller 26 or 24 is pulled downward and the shape material '34 is being pulled, the other puller 24 or 26 is pulled. The clamp 36 is pulled upward and moves back toward the extruder 1°. This other puller 2
The reason why the clamp 36 of the puller 4 or 26 is raised is to prevent it from colliding with the clamp 36 of the puller 26 or 24 that is moving forward.

When the puller 24 has traveled an appropriate distance along the rails 16b118b as shown in FIG. (Not shown) 8 are placed on top. Thereafter, the puller 24.26 is moved below the clamp elevating device 40.42 and the grip 52 is engaged with the chuck 48.50 (FIG. 2);
Then, the cylinders 44 and 46 are actuated to pull up the clamp 36b, which had been in the lowered state, and lower the clamp 36a, which had been in the raised state.
6a grips the mold material 34 and pulls the mold material 34. In order to replace this, the puller 24 moves back toward the extruder 10 (FIG. 3).

In this manner, while one of the pullers 24 or 26 is pulling the profile 34, the other puller 26 or 24 moves back, making it possible to continuously pull the extruded profile.

As for the profile pulling device of this extruder, the puller 24.2
Reference numeral 6 is a non-self-propelled type, which is driven to travel by a traveling drive device (driving wheels 28, etc.) external to the puller, and the vertical movement of the clamps of the puller 24, 26 is also performed by the vertical moving devices 4o, 42 external to the puller. This is done by Therefore, it is not necessary to install a traveling drive device and a clamp vertical movement device for the puller 24, 26, and the device configuration becomes simple. In addition, the pullers 24, 26 themselves are also lightweight, and the rails 16, 18, supporting mechanisms (not shown), etc. provided therewith can also be made lighter in structure.
