Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a forming machine for forming protrusions for drawer assembling, and the present invention relates to a forming machine for forming protrusions for drawer assemblies, and a new lateral movement process is incorporated into the working process of a conventional forming machine for forming circular protrusions for drawer assemblies. The present invention relates to a forming machine for forming an elliptical ridge for assembly of a drawer.

The applicant has devised a drawer assembly shown in FIG.

Among these, the one in which the protrusion for assembling the drawer shown in Fig. 2 is formed into an elliptical protrusion has a larger joint area and a hook part is formed when drawing out than one in which the protrusion is formed into a circular protrusion. This increases the strength of the assembled drawer.

However, although there is a dedicated machine for forming the above-mentioned circular protrusions, there is no dedicated machine for forming elliptical protrusions.

An object of the present invention is to provide a novel drawer assembly protrusion forming machine with a simple structure that can form such an elliptical protrusion simply and quickly.

Hereinafter, the present invention will be sequentially explained according to an illustrative embodiment.

A is a forming machine for forming protrusions for drawer assembling, in which a rough cutting drill 1 is disposed on the lower stage and a finishing forming drill 2 is disposed on the upper stage, which can freely move up and down.
A table 4 which is laminated and fixed and is equipped with a lateral movement adjustment device.
It is composed of, etc.

The drill housing a is fixed with its upper and lower sides sandwiched between horizontal frames 5 and 6.

Both ends 5a, 6a of each of the frames 5, 6 protrude from both sides of the housing a, and struts 7, 7 that guide the projecting ends 5a, 6a up and down pass through them.

The upper and lower ends of the guide columns 7, 7 are fixed to the ceiling 8a of the gate-shaped frame 8 and to a frame 10 integral with the pedestal 9 of the table 4.

A motor 11 for operating the rough cutting drill 1 and a motor 12 for operating the finishing forming drill 2 are mounted above and below the center of the rear surface of the drill housing a.

Further, the upper end of a rod 13 that moves up and down by air is pivotally attached to the center of the lower frame 6 of the housing a.
The lower end of the rod 13 passes through an air cylinder 14 mounted within the frame 10.

Further, in front of the lower frame 6, an adjustment plate 15 is fixed in the vertical direction for simultaneously aligning the front end surfaces of the plurality of drawer side plates 3 stacked on the table 4.

A dovetail fitting part 16 is formed on the lower surface of the table 4, and is adapted to fit with a fitting part 17 on the upper surface of the pedestal 9.
An air cylinder 18 attached to one side of the pedestal 9 and a rod 19 connecting the cylinder 18 and one side of the table 4.
This allows the table 4 to be moved laterally.

This lateral movement is adjusted by a lateral movement adjustment device.

A bracket 20 for the stopper of the lateral movement adjustment device is erected on the other side of the pedestal 9, and is loosely fitted through the erected piece 20a of the bracket 20 so as to connect to the side surface 4, which is the opposite side of the table 4.
An adjustment nut 22 is screwed into the gap between the upright piece 20a of the bolt 21 implanted in the table a and the table side surface 4a.

The adjustment nut 22 is moved from side to side to increase or reduce the distance between its side surface and the upright piece 20a or side surface 4a, thereby adjusting the range of movement of the table 4 from side to side.

The table 4 is provided with an adjustment handle 23 for determining the position of the protrusion 33 protruding from the drawer side plate 3.
This allows the scale side wall 24 to be moved left and right.

This side wall 24 is normally a fixed side wall, and a pressing plate 27 that presses the side surface of the drawer side plate 3 by an air cylinder 26 is provided on the other opposing side wall 25 so as to be movable left and right.

The side walls 24 and 25 support the beam 28 in a gate shape, and the beam 28
An air cylinder 29 is provided above 8.

A rod 3 passing through the beam 28 from below the cylinder 29
0 is connected to a horizontal pressing plate 31 that presses the drawer side plate 3 stacked on the table 4 from above.

32 is an overhanging table extending in front of the table 4.

Next, the special operation of the drawer assembly protrusion forming machine constructed as described above will be explained.

First, a plurality of drawer side plates 3 are stacked on the table 4 and the overhanging table 32, and their front ends are butted against the adjustment plate 15, and the position of the protrusion 33 to be formed is determined by the scale side wall 24, and this is and press plate 2 from above.
7 and 31 to fix it.

At this time, the adjusting nut 22 is moved to the left or right depending on the long diameter of the protrusion 33 to be formed, and a predetermined interval is left on the side surface thereof.

Further, at this time, the drill housing a is located above and faces above the end surface of the uppermost drawer side plate 3 that is stacked.

Subsequently, the air cylinder 14 is operated to move the rod 13 downward.

At this time, the end face of the drawer side plate 3 is first notched into a rectangular shape by a rough cutting drill 1, and then a trumpet-shaped notch is cut into the inner mouth and opening of the rectangular notch by a finishing drill 2.

The protrusion formed by this downward stroke is a plain protrusion that is longer by a predetermined amount than the major diameter of the elliptical protrusion 33 having a regular major diameter.

This long dimension d is removed in the upward stroke described later.

After the downward stroke is completed, the air cylinder 18 is activated and the rod 19 presses the table 4.

At this time, the table 4 moves laterally on the pedestal 9 until the nut 22, whose movement interval is adjusted, abuts against the upright piece 20a.

Its moving distance is equal to the dimension d mentioned above.

The table 4 is stopped due to the collision between the nut 22 and the upright piece 20a, and then the air cylinder 14 is operated in the opposite manner to the above, and the rod 13 is pushed up and the drill... Rise.

As a result, the finish forming drill 2 scrapes off only one side of the bare protrusion 33 formed during the downward stroke by the above-mentioned dimension d, and finishes the protrusion 33 with the regular dimensions (
(See Figure 5).

As described above, in the present invention, in a forming machine in which a rough cutting drill is disposed in the lower stage and a finish forming drill is disposed in the upper stage, the drill housing moves up and down to form a protrusion for assembling a drawer. Since the drawer assembly protrusion is equipped with a drive device that laterally displaces the positional relationship between the drill housing and the table that receives the drawer side plate, and an adjustment device that regulates the amount of displacement, the drill housing After forming the bare ridges on the end of the drawer side plate during the downward stroke, the finishing drill can be positioned so that the regular finishing ridges are formed there during the upward stroke, so that the drill will not change over time. Even if it wears out, accurate protrusions are always formed, and the drill can be used to its full potential, making it economical and providing remarkable effects.
