Abstract

PURPOSE:To manufacture a titled molding without wasting material by holding a mold material having sectional form of a groove provided with raised drawing edge between the notched face of a pushing jaw and the receiving face of a receiving jaw and turning the two jaws. CONSTITUTION:The end of axis of a mold material 1 having sectional form of a groove and provided with a notch and raised edge 2a is put on the receiving face 3a fitting the receiving jaw 3 to the groove-shaped concavity, and the edge 2a is hung on the right angled side 3b. Then, the pushing jaw 4 is advanced by a driving cylinder 4a and pressure contacted to the material 1. When a rotary disk 6 is driven under this condition, jaws 3, 4 unified by a frame 5 rotate holding the material 1, and the curved face 3c of the jaw 3 pressure contacts to the longitudinal axial line part 1a, and bends it according to the curvature of the curved face. On completion of the bending work, the central part is cut by a cutting device 8, and two products are obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method C for manufacturing a molding having an exposed portion.

Conventionally, this type of molding is done by first cutting the molding material to a length slightly longer than the length required for the product.
Its left and right sides are supported by clamps B" and C=,
While applying tension from both sides, the clamp Bt moves in an arc shape to lower the molding material insert @ Cl:: It is bent by pressing and moving (see Fig. 1). After this folding process,
The left and right end sides C: are crushed when gripped with clamp B and have a wavy shape c2 (see Figure 2). product b
When obtaining smbM (: is done by cutting at the center part (see Figure 3).Finally 4:, form a notch C for attaching the molding to the two ends 11As from which the crushed part has been removed. Then, the residual limb edge d is raised and squeezed,
Furthermore, perform a trimming process to make the edge a smooth surface e.
It is said to be the second (4th wJ#Jli) product.

However, if this is done, a crushed portion inevitably occurs, which must be cut and collected, resulting in a huge waste of material.

The present invention enables bending processing without wasting such materials (:
It is an object of the present invention to provide a method for manufacturing a molding. In other words, the present invention ζ: In the method for manufacturing a molding, the length dimension required as a product -: Cut molding material 6: 1) Hold the jaws and the pushing jaws to prevent crushing, and [2] For the rear support, rotate the jaws and pushing jaws horizontally on an arcuate trajectory. The cam surface to be bent is pressed against the cam surface to be bent in the direction of longitudinal force.
It is designed so that it can be processed in a bending process before it is necessary to perform tang processing.

Hereinafter, this will be explained based on the fifth to ninth illustrated embodiments, and the workpieces are as follows. (See Fig. 5 a, b, c) is a cross-sectional substantially groove-shaped 4: extruded molding material 1, and its interior 1=
A core material of aluminum foil is embedded. The molding material l is cut to the required length for the product, including the drawing process of the residual limb edge of approximately 5 to 10 smf 4 degrees, and the edge side that requires bending is pre-cut for attaching the molding. A notch 2 is formed. It was. The stump edge 4: is drawn and has two rising edges.

Like this C: For the molding material 4 prepared in advance, -
In the cutting process, a new part of the shaft is processed.

The machining machine (see Figure 6) is equipped with a receiver 113 for gripping the machining end of the molding material and a push jaw 4. The jaw 3 of the receiver is formed with a front face 3m and a substantially right angle side msb which becomes the receiving surface of the rising edge 2a of the molding material l.
Hold and W! This receiver II 3 also forms a curved surface 3 @ that bends the axis of the molding material 1. This receiver II 3 is integrated with the cam mold (:). The push jaw 4 is movable by a drive cylinder 41 (it is composed of two parts, and its four-pointed tip has an outer part 4b and an inner part 4e which are scissored together. One part 6 has a receiving notch 4d, and nine parts C have a protrusion 4 that presses against the rising edge 2a. It is attached with spring 4f so that it can be deflected freely.
Among these, the elastic deviation C of 1[4e] causes the pressing surface of the pressing jaw 4 to take on a roadside L-shape including the protrusion 4. The pusher 4 and the receiver are integrally connected to the jaw 3 by a frame device that guides the back and forth movement of the pusher jaw, and both are configured to be able to rotate on an arcuate trajectory by driving the rotary disk 6. In the illustrated embodiment, two bending machines are placed on the left and right sides of the machine that simultaneously forms two pieces of molding, and the center position (: indicates the cutting machine 8 that cuts the ridge material received by the guide). are located.Also,
For the cam type, the receiver can also be a separate piece from the jaw and fixedly placed on its own.

This bending machine: On the other hand, the molding material 1 has the shaft end side facing the receiving surface 3a so that the receiving part 3 is fitted into the groove-shaped recess, and also receives the rising edge 2a and has a substantially right angle 1
11i3bl: , @stop arrangement (see Figure 7 1).

Next (:, When the pressing jaw 4 is moved forward with the drive cylinder and presses the molding material l from the outside, the abbreviated pressing surface of the pressing jaw 4 presses against the molding wood 16: the receiving surface of the jaw 3. The molding material 1 is clamped between 3 m + approximately right angle side msb (Fig. 7 b#M). When this suppressing clamping is performed at both ends of the molding material 1, the molding material is fixedly supported by the bending machine 4. In this state, the rotary disk 6 is driven so that the sail material 1 is clamped by the receiver @[3 and the pushing jaws 4 integrated with the frame device].
As a result of the horizontal oscillation, one part of the receiver II3 comes into pressure contact with the longitudinal axis portion 1a of the molding material I. As a result of this pressure contact drive (2), the molding material 1, in addition to the action of the inner position 4e that suppresses the rebound of the push@4, has a rising edge 2a that is connected to the central protruding portion 4 and the right angle side [3b of the receiver I[3]. Direction at right angles between (: 9 held in place, holder 1ls and push 1) Direction of ejection from between 4: i: It does not shift.
The molding material 11 is pressed against the stone and the wrinkle axis portion 1a is folded according to the curvature I of 3 on one side (see Figure 8). When this bending work is completed, in the illustrated embodiment, the cutting device 8 cuts the left and right parts from the central part, and removes each from between the jaw 3 and the pusher WA4. If it occurs,
Trimming it 1: Make it more product.

In addition, in the above-mentioned nine examples, it was applied to the case of simultaneously molding two products, but this was applied to the case of molding one product C:
can also be applied. In this case, C: may be fixedly supported by an appropriate mechanism attached to the processing machine (:) on the end side which is not subjected to the orchid processing.

As described above, according to the present invention C: the manufacturing method of such a molding (:), when the end of the receiver is clamped between the pressure receiving surface of the jaw and the approximately L-shaped pressing surface of the pushing jaw, a crushed portion occurs. The required length dimension t:f/R of the molding material and two pairs [7 bends and 7 JO processes can be added to save material, and the longitudinal bending process can be done appropriately. You will be able to do this.
