Description

Description: TECHNICAL FIELD The present invention relates to a method and an apparatus for pressing an end of a sash bar of an extruded aluminum material.

[Problems to be Solved by Conventional Technology and Invention] Conventionally, end processing of a sash bar of an extruded aluminum material is performed by manually inserting the sash bar into a die set mold by hand. By inserting the die set type into the sash bar,
Processing positioning is possible, but versatility is poor. In recent years, while the tendency for small-lot production of various types has increased, there has been a problem of an increase in cutting time, an increase in the cost of the die set type, and an increase in the die set type.

Under these circumstances, there is a strong demand for automation and efficiency of production of various and small quantities. Although it is conceivable that only the sash bar is automatically transported, it is necessary to replace the sash bar with a die set type when processing is changed to a different type of sash bar. Therefore, it is conceivable to reduce the number of cases in which a plurality of presses are provided to change the setup, or to automatically carry out a die set to automatically set and change the setup, for example, but the number of die set molds does not decrease. Therefore, even if FMS (flexible production method) and CIM (computer integrated production method) are used in the above-mentioned procedure, the production cost of die set molds increases, and the space for storage due to the increase in die set molds eventually increases. It is unavoidable that the cost of maintenance and management will increase.

The present invention solves the above-mentioned problems in the processing of a sash bar of an extruded aluminum material, and does not use a die set type in the processing of various types of sash bars, or can minimize the number of die set types and can automate the conveyance. It is an object of the present invention to provide a suitable pressing method and processing device.

"Means for Solving the Problems" When examining the end portion of the sash bar of the extruded aluminum material, most is punching and shearing, and can be processed only with the upper and lower shearing press dies. Therefore, even when using a die set type by attaching a positioning function to the sash bar conveying side, the die set type does not require positioning means for the work, and only the upper and lower press types need to be set. Depending on the type, a press die may be directly attached to a press machine. When the positioning member is removed from the die set mold, only the upper and lower press dies are provided, but the types of the press dies are far less than the entire die set dies.

Accordingly, a first aspect of the present invention provides a press machine capable of aligning and mounting various types of press dies which are selectively combined with element processing on a plurality of types of sash bars formed so as to have different end portions, and Using a device for selectively positioning the sash bar with respect to each press die and a sash bar handling device having a device for allowing the sash bar to enter the press die to a predetermined position, the sash bar is processed according to the process of processing the end of the selected sash bar. It is positioned at a required press die portion by the handling device, is processed by entering the press die to a predetermined position, and after processing, the sash bar is withdrawn and moved to the press die position of the next process to process the end portion of the sash bar. The process is repeated and the end processing required for the selected sash bar is performed. It is obtained by the bar of the processing method.

According to a second aspect of the present invention, there is provided a press die which is erected and arranged in a base shape in the horizontal and vertical directions according to the rectangular coordinates, drive means for the press die provided for each press die, and the press die and the drive means. Aluminum provided with a numerically controlled transfer device including a holding machine frame, means for positioning the sash bar in the left, right, up and down directions with respect to the surface on which the press mold is arranged, and means for moving the press mold forward and backward for constant positioning. This is a sash bar processing device for extruded materials.

According to a third aspect of the present invention, a plurality of press dies attached to a drive device are arranged on a horizontal straight line, a guide rail is provided in parallel with the arrangement direction of the press dies, and a saddle is movably mounted on the guide rail. A horizontal guide rail is provided on the saddle in a direction orthogonal to the guide rail, a cross slide is engaged with the guide rail, a column is erected on the cross slide, and a vertical guide is provided on the column. A vertical slide having a sash bar grasping device is engaged with the guide, and a driving device for each of the saddle, the cross slide and the vertical slide and a control device for controlling the movement of the saddle, the cross slide and the vertical slide are provided. This is a sash bar processing apparatus for extruded aluminum members.

"Examples" Examples of the present invention will be described below with reference to the drawings.

1 and 2 are schematic views showing a method for processing a sash bar of an aluminum extruded die according to the present invention. FIG. 1 is a front view, and FIG. 2 is a plan view of FIG. In the state where various types of upper and lower press dies 1 are erected, on rectangular coordinates (xy) (x: 1 ... i ... m, y: 1 ... j ... n)
It is arranged in. Each of the press dies has an _{arrangement position such as} 1 _ij (i, j is the press die at the lower left and the abscissa is the order number 1 ... i ... m, and the ordinate is the order number 1 ... j ... n). There is provided a driving means for each of the press dies 1. The press machine is composed of the press dies 1, the respective drive means and a machine frame for supporting them.

The handling device 3 has the grasping device 2, and the sash bar W is positioned and moved according to the xy coordinates, and moves in the z direction perpendicular to the xy plane.
The sash bar W can be moved back and forth toward one of the press dies 1. This handling means is a robot or an autoloader. These movements are controlled by numerical control means.

Almost all of the above press dies are provided with shear dies, square holes,
A round hole, a notch with a semi-circle at the back, and a preparation with a corner at the back are provided according to the size. Such a press die 1 does not need to be regularly arranged according to the processing shape and the size of the processing portion. The press die 1 is provided with a unique code according to the shape size to be processed by the press die 1. A well-known method of setting the press die 1 in a press machine and reading the same by a control device is preferable.

FIG. 3 shows a processing example of the sash bar W. As shown in FIG. 3 (A), the sash bar W of the extruded material has a hollow portion e having a top plate c and a bottom plate d between the side plates a and b, and the side plates a and b are more vertical than the hollow portion e. Protruding ridges a-1, b-1, a-2, b-2 which are extended so as to be close to each other. This example shows a cross section of a vertical frame.

The end of the sash bar W is processed to obtain the sash bar W shown in FIG. In FIG. 3 (E), notches f are formed by shearing the ridges a-1 and b-1 for the lower frame to be assembled from the direction perpendicular to the end of the sash bar W, and then into the tapping groove of the lower frame. A round hole g through which the tapping screw to be inserted is passed is provided in the bottom plate d by shearing, a small screw hole h through which the tapping screw is inserted is provided in the upper plate c by shearing, and the rail of the lower frame of the opening frame is inserted. A method of forming a sash bar W of an extruded aluminum material in which notches k and l are provided in the upper plate c and the bottom plate d by shearing and a square hole p for attaching a door stop member in the bottom plate d by shearing will be described. .

The sash bar W is conveyed by the conveyor 4 in the direction of arrow A in the drawing, and at least one sash bar is waiting at the standby position. The grasping device 2 moved by the handling device 3 grasps the sash bar W at the standby position at the exit of the conveyor 4, and the numerical control device 5 moves the sash bar W to the position of the press die 1 for processing the notch f in accordance with the xy coordinates.

When it is inserted to the depth by the numerical control, the driving device of the press die 1 is energized by the auxiliary function of the numerical control. (After the positioning, the driving device of the press die 1 is energized by the auxiliary function of the numerical control. (This description is omitted.) A notch f is formed as shown in FIG. 3 (B). After the press die is opened, the sash bar W then slightly retreats from the press die 1 in the z direction, and moves to the portion of the press die for punching the square hole p according to the xy coordinates. Then, in the z direction, the sash bar W is sent toward the press die 1 by an amount determined by numerical control, and stops positioning.
One of the square holes p is punched by the press die 1. After the press die 1 is opened, the sash bar W is sent in the x direction by the pitch of the two square holes p, and another square hole is processed by the same press die 1, as shown in FIG. 1 (C). Square hole p
Is formed on the bottom plate d. When the space between the press dies 1 is opened, the sash bar W exits the press dies 1 in the z direction. In the same manner, the sash bar W moves to another press die 1 in accordance with the xy coordinates and is fed into the press die 1 in the z direction, and the notches k and l are formed in the upper plate c and the bottom plate d (FIG. 1 (D)). )) Further, similarly, a small screw hole h is formed in the upper plate c and a round hole g is formed in the bottom plate d (FIG. 3 (E)).

In the above-described method of processing the sash bar of the extruded aluminum material, the press dies are arranged according to the rectangular coordinates. However, the press dies may be arranged according to the rectangular coordinates or may be arranged according to the polar coordinates. Also, the handling device 3

4 to 6 show three views, FIG. 4 is a plan view,
FIG. 5 is a front view, and FIG. 6 is a side view. In this embodiment, when the press dies 1 are aligned on a straight line in the horizontal direction, the handling device 3 moves the sash bar W in the xy direction (left and right and up and down directions) and the z direction perpendicular to the plane of the drawing as viewed in the front view of FIG. Things.

The press dies 1 are arranged in a straight line on the press machine frame 7 integrally or integrally with the bed 6. A line shaft 9 having an eccentric cam 8 is rotatably supported by the press frame 7 below the press die 1 in the arrangement direction of the press die 1. At each position of each press die 1, a guide block 10a provided with a vertical guide 10 is fixed to the press machine frame 7, and a slide block 11 is fitted to the guide 10. A connecting rod 13 having an eccentric ring portion 13a at one end for sliding with the eccentric cam 8;

Is driven by a stepping motor 15 via a belt driving device 12.

A linear guide 16 is provided on the bed 6 in parallel with the direction in which the press die 1 is arranged, and a saddle 17 slides on the guide. A straight guide 18 orthogonal to the straight guide 16 is provided on the saddle 17, and a cross slide 19 slides on the guide.
Column 22 with longitudinal guide 21 on cross slide 19
A vertical slide 23 slides on the guide 21 of the column 22, and the main body 2a of the grasping device 2 is fixed to the vertical slide 23. The grasping device 2 holds the sash bar W between the opposing surfaces of the moving grasping claw 2b engaging with the main body 2a so as to move in a direction parallel to the linear guide 16 and the fixed grasping claw 2c of the main body 2a. Are oriented in the z direction.

In this embodiment, for example, when processing the sash bar W of FIG. 3, the processing of the notch f is performed by the press die _1-1 . Then, the sash bar W conveyed by the conveyor is transferred between the open moving grasping claws 2b and the fixed grasping claws 2c of the sash bar grasping device 2 by a delivery device (not shown) at a position B shown by a two-dot chain line. When the moving grasping claw 2b advances toward the fixed grasping claw 2c and grasps the sash W, the numerical controller drives the z-axis servomotor 27 by a signal of a sensor provided in the grasping device 2 (not shown) via the screw feeder 26. The sash bar W is moved toward the proximity switch 31 provided on the press machine frame 7 by sending the cross slide 19. When the tip position of the sash bar W is detected, the signal is sent to the numerical controller, and the z-axis reference position is stored. The reason for this is that the end positions of the sash bar W to be processed to be processed are not uniform, so that it is necessary to make the z-axis constant as a processing reference.

When cross slide 19 and stops reversed z-axis servo motor 27 subsequently stops, x-axis servo motor 25 is driven, the saddle 17 through a screw feed device 24 is sent to the x-axis direction, the press mold 1 _- Stop at the position where the center of _{1 and} the center of the cross section of the sash bar W coincide with each other, the y-axis servo motor 28 is driven, and the vertical slide 23 is moved via the screw feeder 28,

-1, to seat the b-1 lower surface on the lower mold 1L press die 1 _-1. As a result, it becomes ready for press working. Then, the step motor 15 is driven by the signal of the auxiliary function of the numerical controller, and when the line shaft 9 makes one rotation via the belt driving device 12, the eccentric cam 8 moves the connecting rod 13 up and down, and the connecting rod 13
The slide block 11 is moved up and down via. The slide block 11 is a guide block 10 fixed to the press machine frame 7.
The guide 10a moves up and down, lowers the fixed upper die 1U to form a notch f, and then moves up.

Punch to the press die 1 _-2 center providing the square hole p of the second step (the upper die 1U) the center of a half pitch by press die 1 _-2 between the two square holes p in case of a centered and sash bar It is necessary to offset the center of the cross section of W at the left and right. Once the press mold 1 1 a cross-section left and right centers of sash bar W _-2 after match-half the pitch between the two rectangular holes p
Only faster to may be offset was set to match the one corner holes p centers of the press mold 1 _-2 directly. After the first step by the press die _1-1 , the z-axis servomotor 27
By retracting the sash bar W, it sends the saddle 17 by the x-axis servo motor 25, to match the x-axis direction of the second press die 1 _-2 and sash bar W. And the y-axis servo motor 29

In the same manner, the notches k and l shown in FIG. 3D are processed, but the sash bar W is processed by the same press die 1 for the notches k and l. Therefore, the sash bar W is moved backward by the distance between the upper plate c and the bottom plate d after being retracted once to the same press die 1, and then moves again to be processed. Since the small screw hole h and the round hole g have different diameters, they are machined by different press dies.
