Description

[Detailed description of the invention] This invention is a method for assembling sash members used for window frames, etc. or similar shapes, etc. by connecting the ends or attaching beams. The present invention relates to an automatic processing device for cutting or perforating a shape material.

In general, when assembling a frame or a beam of a shape material such as a sash member, it is necessary to perform several types of processing such as predetermined notches and perforations at the connecting portions at both ends.

Conventional processing devices used for the above-mentioned processing include manual and automatic processing devices, but the workability and blade durability of a plurality of automatic processing devices have been poor.

This idea improves the conventional processing equipment mentioned above,
In addition to automating processing machines with different shapes that perform multiple processes, each machine with different shapes can be selected individually or as needed, and operated simultaneously to easily perform different cuts and holes for multiple processes at the same time. The purpose of the present invention is to provide an automatic shape processing device that can improve workability and improve the durability of blades by stopping unnecessary processing machines.

An embodiment of this invention will be described in detail below with reference to the attached drawings.

A workpiece 1 is inserted into a processing machine 3 installed on a base plate 2. This processing machine 3 is composed of processing machines 3a, 3b, 3c, etc. each having a different shape, and each of these processing machines 3a, 3b, 3c
A motor 5 attached to the side of the main body 4 of the processing device moves a reducer 9 via a V belt 6 and V pulleys 7 and 8 to rotate a main shaft 10. Main shaft 10
The main body 4 is connected by two pillow blocks 11 and 12.
It is pivoted on. The main shaft 10 has claws 2 that protrude laterally.
4 is fixed by a key 14,
An eccentric ring 25 having an annular groove 28 is rotatably inserted adjacent to this ring 13. A spring box 22 is installed on one side of the ring 25, and the claw 21, which is biased by a spring 23 loaded in the spring box 22, is slidably inserted through the side wall forming the groove 28 of the ring 25. The end of an arm 26 is pivotally attached to the other side of the ring 25. The other end of the arm 26 is connected to the end of a slide shaft 38 by a pin 39, and this slide shaft 38 is configured to slide vertically within a movable bearing 37 fixed to the top platen 36 of the main body 4. The on-blade moving plate 41 is attached to the T-shaped groove 40 formed at the upper end of the blade.
The end of the pin 4 is fitted into the movable plate 41.
The on-blade 42 is connected via 3. The pawl 21 energized by the above-mentioned spring 23 has an eleventh
A stepped portion 2 passing through one side wall of the groove 28 as shown in the figure.
1a and a groove 28 formed lower than this step 21a.
The rotation of the main shaft 10 with respect to the other side wall of the groove 28 is formed on the vertical surface of the boundary between the stepped portion 21a and the engaging portion 21b. A slope 29 that is open in the direction is formed. An annular groove 28 is formed on this slope 29.
A wedge 20 fitted therein engages and maintains the claw 21 in a pulled back state against the biasing force of the spring 23. The wedge 20 is located above the eccentric ring 25, has one end pivotally connected to the main body 4 via a pin 19, and the other end fitted into a groove 33 of a side plate 32 fixed to the main body 4 so as to be movable up and down.
The arm 18 is attached to an arm 18 which is urged downward by a spring 27, and the arm 18 is attached to a pedal 15 which acts as a lever using a shaft 16 which is fixed at both ends to the main body 4 as a fulcrum via a shaft 17 suspended below. connected.

The vertical movement of the other end of the arm 18 is restricted by pins 34 and 35, and the wedge 20 and eccentric ring groove 2
In addition to preventing wear with the bottom surface of the wedge 20, the groove 28
It prevents it from flying out. Reference numeral 44 is a chip discharge cover, and 45 is a cover for the V-pulley.

In the above configuration, the trimming machines 3a, 3b, and 3c share the main shaft 10 and the shaft 16, and are configured independently.

Next, the operation of the above configuration will be explained.

Now, with the main spindle 10 rotating, the cutting machine 3
When stepping on petal 15 to activate a, petal 1
5 acts as a lever with the shaft 16 as the fulcrum, and
One end of arm 18 is pivoted via shaft 17 (shaft 19)
and lift the other end upward. At this time, the wedge 20 fixed to the arm 18 is disengaged from the claw 21, and the claw 21 is biased by the spring 23 in the spring box 22.
Move in the direction of the arrow shown in the figure. The pawl 21 engages with the pawl 24 of the ring 13 to rotate the eccentric ring 25, and the rotation of the main shaft 10 is controlled by the arm 26 pivoted on the side surface of the eccentric ring 25, the slide shaft 38 connected thereto, and the slide shaft. It is transmitted to the on-blade 42 via the on-blade moving plate 41 connected to the on-blade 38 . At this time, the on-blade 42 moves up and down by the amount of eccentricity of the eccentric ring 25 attached to the main shaft 10.

When the pedal 15 is released, the other end of the arm 18, which is always urged downward by the spring 27, immediately returns to its original position (the position before stepping on the pedal 15), and the wedge 20 fixed to the arm 18 The rotation of the eccentric ring 25 engages the slope 29 of the pawl 21 again and moves the pawl 21 in the direction opposite to the arrow direction shown in FIG. 21 is released, and the on-blade 42
The movement of becomes stationary. A braking mechanism may be provided on the eccentric ring 25 in order to smoothly stop the on-blade 42. This braking mechanism includes, for example, a square piece 30 attached to the arm 18 as shown in FIG.
Attach the spring-loaded pin 31 to the
The tip of the eccentric ring 25 is configured by slidingly contacting the outer peripheral surface of the eccentric ring 25. According to this braking mechanism, the pawl 21 and the pawl 24
The eccentric ring 25, which is disengaged from the ring 25, rapidly reduces its rotational speed, and the on-blade quickly comes to a standstill, and the wedge 20 hits the slope 29 of the claw 21 smoothly and accurately without causing a large impact. engaged.

As described above, the main shaft 10 is constantly rotating,
The mechanism for operating or stopping the on-blade 42 operates while the main shaft 10 is rotating.

In this way, by moving the on-blade 42 up and down, the workpiece 1 is cut or drilled in a predetermined manner.

In this embodiment, a device equipped with a pulling mechanism from below has been described, but the present invention is not limited to this, and the on-blade moving plate 41 is extended to the top surface of each cutting machine, and the on-blade moving plate 41 is Needless to say, cutting can also be performed by pressing the blade from above. In this case, by adjusting the length of the slide shaft 38, it is possible to operate a plurality of cutting machines at different heights. Furthermore, the present invention allows many cutting machines to be operated by expanding the base plate 2 or by connecting the main shaft 10 of a processing machine equipped with two or more cutting machines with a joint. be.

As described above, according to the present invention, it is possible to automate processing machines with different shapes that perform multiple processes, and to operate each machine with different shapes independently or as necessary, and operate them simultaneously to make different cuts and holes for multiple processes. Machining can be done simultaneously and easily, workability is improved, and unnecessary processing machines can be stopped to improve the durability of the blade, so its practical value is enormous.
