Description

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 an extruded profile for an aluminum sash cut into a predetermined length at a desired angle. Relates to an end cutting processing unit applied to a fully automatic processing machine for continuously processing various machining such as pressing and punching on the end of the extruded profile.

[0002]

2. Description of the Related Art In general, not only the above-mentioned aluminum profile but also the end of a long article cut to a predetermined length is subjected to various kinds of processing necessary for final assembly. Looking at the end processing of the aluminum profile, not only various machining such as notching, punching, punching etc. are made on the peripheral surface of the end, but also the processing shape is various, for example shown in the figure. In many cases, a part of the end of the profile is notched into a V shape. Most of these processes are mainly cutting processes, and generally, the processes are manually performed, and a series of processes that remain after waiting for one process to be completed are often performed in sequence. Therefore, a lot of manpower is required, work efficiency is reduced, and it is a cause of hindering improvement in productivity due to automation and the like.

Conventionally, for example, Japanese Unexamined Patent Publication No. 3-198930 discloses a fully automatic press working method for an aluminum profile and the same working machine. According to the press working machine disclosed in the 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 the plane coordinate system and in multiple stages. At the time of processing the end of the aluminum profile, the gripping device horizontally grips one of the profile that is sequentially supplied side by side from the supply device arranged on the side of the processing device. It is transferred to the set press working unit along the X and Y axes, and then the work end of the same shaped material is moved in the direction (Z-axis direction) of pushing into the mold of the press working unit to move the same metal. The end to be processed is pushed into the mold to perform the desired press work. When this processing is completed, the above-described operation is repeated, and press working is sequentially performed on the end portion of the shape material from the next time.

[0004]

However, conventional automatic processing machines, including the processing machines disclosed in the above publications, are designed mainly for press working, which is a general method in the past, and have a mechanism. In addition, we do not assume that we will develop a cutting process unit with complicated control, and often perform the necessary cutting process separately. By the way, since the profile is generally made of a hollow extruded material having a complicated cross-sectional shape, when attempting to form a notch of the same shape in the opposing portions, if cutting is performed, only one cutting is required. According to the press working, it is necessary to reverse the front and back of the shape member and punch out the same shape on each surface, or to use a special die plate. In particular, when it is desired to cut out a part of the shape member obliquely at a desired angle, the cutting process is most effective.

The profile having a sharp edge at the tip after the cutting process as described above is temporarily moved to a storage location or directly moved to the next press machine. At the time of this movement, there is a risk that the processing edge will touch the operator and hurt the skin or pierce the body, and if possible, cut processing and press processing on the same processing machine from the viewpoint of work efficiency and safety. Most desirable to do.

The present invention meets these needs,
The purpose is to be able to cut diagonally with a desired angle,
Further, it is to provide an end cutting processing unit for a long shaped member which not only realizes labor saving and secures safety but also has a simple structure which is highly effective as a single machine.

[0007]

The above object is to provide a horizontal main spindle which is provided on a horizontal substrate and vertically moves up and down together with a rotary drive unit toward the same substrate, and which is fixedly mounted on one end of the main spindle. A rotary cutting tool which is driven and rotated in a vertical plane by means of a profile member gripping means which is installed on the substrate, positions and positions a machining end of a long profile member in an operating region of the rotary cutting tool, and fixes the shape. End face positioning means for determining a processed end face position of the material, and tool angle indexing means for rotationally indexing the cutting tool at a desired angle in a horizontal plane about a vertical support axis of the rotary drive part. Achieved by a featured end profile cutting unit.

According to a preferred embodiment, the shape holding means has a holding and fixing means for holding the shape from above and below and left and right, and at least the left and right holding and fixing means adjust a cutting depth by a rotary tool. Have means,
The end face positioning means of the profile has cutting position adjusting means for adjusting the cutting position in the length direction of the profile.

[0009]

The operation when the end cutting processing unit of the present invention is incorporated in a fully automatic processing machine capable of processing a large number of processings in the same machine will be described below. Of course, the present invention can also be used as a single machine without being incorporated in the same processing machine.

Now, the profile transfer means receives one profile from the profile supply standby unit, moves it in the X-axis and Y-axis directions while holding it horizontally, and cuts the profile according to the present invention. Transfer to the front of the unit. At the time of this transfer, the rotary tool drive unit is rotated by a desired angle in the horizontal plane by the rotary angle setting means, and the cutting processing angle by the rotary cutting tool has already been determined.

Even at this time, the profile transfer means continues to operate, and the chuck position of the profile is set to a predetermined position by a rotating mechanism such as a crank mechanism, and then the center of the front face of the end cutting unit is set. The tip of the profile is advanced in the Z-axis direction so as to be placed on the upper surface of the installed profile mounting table until it comes into contact with the end face positioning means. At this time, the profile holding position of the cutting depth setting member is also preset, and when the profile is guided to the upper surface of the mounting table, at the same time, the side surface thereof is also guided by the cutting depth setting member. Become.

When the position of the end portion of the profile is determined by the end face positioning means, the movable jaw part which is installed above the profile mount and faces the movable jaw part of the left and right gripping means is moved,
Hold and fix the profile from above and below and from the left and right. Thus the profile W
When gripped and fixed, the rotary tool drive unit starts operation to drive and rotate the rotary cutting tool, and at the same time the drive unit is vertically lowered by the vertical drive unit together with the rotation angle setting unit, so that the end portion of the profile is removed. Cut at the desired cutting angle and cutting depth.

When the cutting work is completed, the holding by the shape holding means is released, and the shape transferring means moves back to a predetermined position on the front surface of the processing portion having a large number of processing units in a plurality of stages, and then in the X-axis and Y-axis directions. To the front of the next predetermined processing unit, and after the known processing is performed in the same unit, the same operation is repeated and the necessary processing is sequentially performed, and from the discharge section. Discharge outside the processing machine.

When the same shape material is discharged, the shape material transfer means again moves to the shape material supply standby device, where the next processed shape material is received and transferred to the front surface of the end cutting unit. Next, the above-described operation is repeated, and the desired number of end portions of the profile is cut. When changing the cutting angle, the rotation angle setting means automatically rotates a predetermined angle based on the production management data stored in the control unit to determine the cutting angle of the rotary tool driving unit.

FIG. 2 is an overall perspective view showing a schematic configuration of an automatic processing machine in which the cutting processing unit of the present invention configured as described above is incorporated together with other press processing units arranged in multiple stages.

The structure of the automatic processing machine will be briefly described below. The profile W is formed on the front surface of the processing section 18 in which a large number of press processing units PU are arranged side by side along with the cutting processing unit CU of the present invention. A profile transfer device 19 for positioning and transferring in three axial directions of X axis, Y axis and Z axis is installed. According to the present embodiment, the same-shaped material transfer device 19 includes horizontal sliding rails 19a arranged in parallel in the vertical direction for guiding and guiding the shaped material to the left and right (X-axis direction), and the same horizontal sliding rail 19a.
A vertical slide rail 1 which is slidably fitted to and is used to transfer and guide the profile in the X-axis direction and in the vertical direction (Y direction).

It consists of 9c.

The operating means for positioning and moving the vertical sliding rail 19b along the horizontal sliding rail 19a and the operating means for positioning and moving the carrier arm 19c along the vertical sliding rail 19b include: Servo motors 20 and 21 and a ball screw (not shown) are used respectively. Of course, other actuation mechanisms may be employed.
A well-known hand robot mechanism and a rodless cylinder are used as the operating means of the carrier arm 19c.

On the other hand, on one side of the profile transfer device 19, there is installed a profile supply standby device 22 for sequentially supplying a large number of profiles W in parallel and arranging each profile W in a standby posture. ing. The profile W is supplied by a belt conveyor (not shown) as usual, and the profile W supplied to the standby position is supplied.
