DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting unit for partially cutting the end of an extruded profile for an aluminum sash, for example, cut to a predetermined length. The present invention relates to an end cutting unit applied to a fully automatic processing machine that continuously performs various types of machining such as pressing and drilling on the end of a profile.

[0002]

2. Description of the Related Art In addition to the above-mentioned aluminum profile, the end of a long article generally cut to a predetermined length is subjected to various processes required for final assembly. Looking at the end processing of the aluminum profile, not only various processing such as notching, punching, and punching are performed on the peripheral surface of the end, but also the processing shapes are various, for example, as shown in FIG. Often, a part of the end of the profile is cut out in the shape of a "ku". These processes are mainly performed by cutting, and are generally performed manually, and a series of processes that remain after one process is completed are often performed sequentially. Therefore, it requires a lot of manpower, lowers the work efficiency, and hinders improvement in productivity due to automation or the like.

Conventionally, for example, Japanese Unexamined Patent Publication No. Hei 3-198930 discloses a fully automatic press working method and a working machine for an aluminum material. According to the press working machine disclosed in this publication, a large number of press working units equipped with different press dies each having a unique code are arranged in parallel on the X-axis and Y-axis of a plane coordinate system and in a multistage manner. At the time of processing the end of the aluminum profile, the gripping device horizontally grips one of the profiles sequentially supplied side by side from the supply device arranged on the side of the processing device. The workpiece is transported along the X-axis and the Y-axis to a set press working unit, and then the processed end of the same material is moved in a direction (Z-axis direction) in which the work end of the same shape is pressed into the die of the press working unit. The end to be processed is pushed into the mold to perform desired press working. When this processing is completed, the above-described operation is repeated, and the next and subsequent end portions of the profile are pressed sequentially.

[0004]

However, conventional automatic processing machines, including the processing machines disclosed in the above-mentioned publications, are mainly designed for press working, which is a general method in the past, and are not suitable for mechanical mechanisms. In addition, it is not assumed that a cutting unit having complicated control will be developed, and necessary cutting is often performed separately. By the way, since the profile is generally made of a hollow extruded material having a complicated cross-sectional shape, when forming a notch of the same shape in an opposing portion, the cutting process can be performed only once, According to the press working, it is necessary to invert the profile and punch the same shape on each side, or to prepare a special die plate. In particular, in the case where a part of the profile is to be cut obliquely at a desired angle, it is efficient to employ a cutting process.

[0005] As described above, the shaped material having a sharp edge at the tip after the cutting process is temporarily moved to a storage location or directly moved to the next press machine. At the time of this movement, there is a danger that the processing edge portion touches the worker to injure the skin or pierce the body, and if possible, cut and press the same processing machine in terms of work efficiency and safety. It is most desirable to do so.

[0006] The present invention addresses this need.
Its purpose is to make it possible to cut two places with a single unit, not only to realize labor saving and safety, but also to have a simple structure that is effective as a single machine and has a simple structure. An object of the present invention is to provide an end cutting unit for a material.

This is achieved by an end cutting unit for a long profile, wherein two sets of profile gripping means are provided .

[0008] The profile gripping means is for positioning and gripping the profile vertically and horizontally and has a positioning means for the front end surface of the processed portion. The position where the two sets of profile gripping means are provided is provided. Are disposed at substantially horizontally symmetric positions on a horizontal line which is the movement locus of the rotation axis of the cutting tool, and are disposed at obliquely symmetric positions within the upper and lower cutting regions of the rotary cutting tool. There is a case where the gripping means has a means for adjusting the vertical gripping position.

[0009]

An example of the operation of the automatic cutting machine disclosed in the above publication in which the end cutting unit of the present invention is incorporated will be described. Is moved in the X-axis and Y-axis directions while being held horizontally, and the section W is transferred to the front surface of the end cutting unit. Here, the profile transfer device starts to operate, and the processing end of the profile is rotated to a predetermined posture by a rotating means such as a crank mechanism, and then installed on one of the left and right sides in the end cutting unit. The first
It is advanced in the Z-axis direction toward the holding means. At this time, at the same time, the side surface positioning means of the first gripping means guides while determining the side surface position of the profile. The tip position of the machined end of the section is
This is performed by end face positioning means for fixing the position of the processing end of the profile. Next, the profile is held at the same position from above and below and from left and right to be immobile. When the section is gripped, the drive section starts rotating the rotary tool and moves toward the section, cutting the end of the section to a desired cutting width.

When this cutting is completed, the gripping of the profile by the gripping means is released, and the profile transport device is retracted to a predetermined position on the front surface of the processing section. Next, the profile is moved to the front position of the second gripping means installed on the other side in the end cutting unit. Subsequently, the profile transfer device starts operating, rotates the profile 180 ° about its axis, and advances the machined end of the profile in the Z-axis direction toward the second gripping means. At this time, the side surface position of the profile is determined by the side surface positioning portion of the second gripping means. Further, the tip position of the processing end of the profile is determined by processing tip positioning means provided to face the processing end surface of the profile.

When the profile is positioned and gripped at the same time by the second gripping means in this way, the drive unit drives the rotary tool to rotate and moves the end of the profile W to a desired position while moving horizontally to the cutting end position. After cutting to the cutting width, the cutting process of the shape material twice is completed.

As described above, according to the end cutting unit of the present invention, different cutting processes are performed in the same unit using the same rotary cutting tool. The above-described cutting operation is automatically performed in accordance with a processing procedure set in advance in the control device, and is linked with the control operation of the profile material transfer device, so that the automatic processing machine can perform the pressing operation together with the pressing operation. Cutting is performed automatically.
