Abstract

<P>PROBLEM TO BE SOLVED: To provide a support bender which can be carried easily by a single person. <P>SOLUTION: Front and rear columns 12 are fixed slidingly in the vertical direction with a connecting beam 15. The connecting beam is fixed with an upper Yagen(V-shaped punch) fixing beam 14, and the upper Yagen 1 is bolted to the lower face of the beam in the horizontal manner allowing the Yagen to be pulled out to the left or the right. A lower Yagen(V-grooved die)3 is located under the upper Yagen and fastened with a L-bolt 5 to the lower Yagen table 4. To perform forming of a steel plate or the like, the head of a hydraulic jack 9 is attached to the lower Yagen. When an oil pump 10 is put into operation, the steel plate placed on the lower Yagen is bent into the designated angle. When a switch 8 is stepped on after finishing, the upper Yagen fixing beam together with the four columns returns back to its original position by the force of a spring 13, and the formed steel plate can be removed. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a support vendor, and more particularly to a small and lightweight support vendor that enables processing by bringing it to the site.
[0002]
[Prior art]
The existing products are mass-produced large precision benders, or mass-produced machines that are installed on the floor on the same production line even with a processing width of about 300 m / m, and other small machines are table-top or cast-old floor-standings. There are no vendors suitable for moving with a foot type such as a mold bender or a shearing machine.
[0003]
[Problems to be solved by the invention]
For example, I have never heard of machine tools that exist in tens of thousands of ships around the world for repairs. When the SDF is dispatched for disaster recovery, I also hear that I want machine tools that can correct bent iron and board materials, schools, etc. If there is a small vendor that prototypes parts between an alumni and an adjacent desk instead of a large machine for trial production and research such as robots and solar cars, then our old small vendor was bought. Was.
[0004]
[Means for Solving the Problems]
The main problem is that the support vendor can move lightly with one's own power, which is described in claims 1 and 2 of the claims. The point was written in claim 3.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The support bender of the present invention was developed from an old 7 ton hand bender. The old machine was used for the production of artificial arms, artificial legs, wheelchairs, etc. For manufacturing truck hoods, prototype electronic component chassis, etc., assembling building sash building materials, parts companies such as road guardrails, hospital bed medical equipment storage shelves, labor saving devices, electronic application control devices, building hardware stainless Processing companies, prototypes for prototypes of automobile parts, children's education for elementary schools, stage equipment manufacturing companies, car repair shops, large schools for robot prototypes, universities for solar car prototypes, mobile phone manufacturers, etc. We are still expecting new products from many companies.
[0006]
An embodiment of the present invention will be described with reference to FIG. FIG. 1 is a perspective view of the whole, in which the hatched portion is a portion that operates during material processing, and the portion without the hatched portion indicates an immovable portion. The main body (2) and the four pillars (12) are mounted so as to be slidable up and down, and the hydraulic jack (9) is mounted on the lower beam (11) where the shaft is pushed up by the hydraulic pressure of the hydraulic pump (10). The upper bevel (1) which was tightened with the (mounting screw) 20 to the connecting beam (15) and the upper bevel fixing beam via the four pillars (12) in reverse by being pushed down (FIG. 8) The dimensions of the iron plate (21) of the workpiece are confirmed by the stopper (7), and the lower bevel (3) placed at the center of the mounting table (6) is L-shaped bolt (4) on the lower bevel table (4). The machine is tightened and fixed by 5) and processed in the order of (FIG. 4) and (FIG. 5). This machine can be easily moved by the movement of the caster (17).
[0007]
FIG. 3 shows that when the iron plate of the workpiece (21) is a thick pipe or the like, the opening is widened as shown in FIG. 3 when the opening is raised to the maximum (FIG. 3). It is possible to make a thin pipe as shown in FIG. 10 and even an iron box as shown in FIG. 10, and to straighten a bent iron bar as shown in FIG. 9 and to make an R-bend as shown in FIG.
[0008]
【The invention's effect】
This portable support vendor can easily adjust the gap between the upper bevel (1) and the lower bevel (3) in addition to the production function of the small bender currently on the market (Fig. 3). It is also possible to straighten thick iron materials such as flat bars or iron plates, and to make large-diameter round pipes, square pipes, C-shaped channels, etc. As a long pipe, the appearance is aesthetically different from the handrails of a city full of seams, and the demand source is required for repair of manufacturing machinery at a souvenir factory in the mountains or in a depopulated area. It is expected that the amount of contribution will be large because the quantity of each country in the world is large and accidents etc. are not small.
Since I have never heard of portable support vendors overseas, depending on this method of enlightenment, it can lead to the discovery of further needs and can respond to the request of the nation, which is a "global product from Japan". I believe it.
[0009]
The greatest advantage of the present invention is the reduction in weight, which brings various advantages, and allows the ship to be repaired to the repair site. Also, in collaboration with alumni at universities, small businesses can store in the eaves when they are finished on the road, bend the handrail of the slope to Yamagami Shrine, and make pipe joints, so even the domestic scenery is elegant. The future development of this support vendor can lead the world in a better direction because it can be replaced.

Claims (3)

In FIG. 1, first, the side plate of the support bender is replaced with four columns (12), and the front and rear columns (12) are fixed by connecting beams (15) so as to be slidable up and down. The upper bevel fixing beam (14) is fixed to the left and right connecting beams (15), and the lower bevel (3) is mounted directly below the lower bevel (3) immediately below the lower bevel (1) with a horizontal mold capable of pulling the upper bevel (1) left or right. Is fixed to the lower bevel base (4) with an L-shaped bolt (5).
For processing iron plates, etc., the head of the hydraulic jack (9) is fixed to the lower bevel table (4), and when the oil pump (10) is operated, the iron plate (FIG. 4) placed on the lower bevel (3) becomes It is bent to a predetermined angle (FIG. 5), and when it is finished, when the left side of the switch (8) is stepped on, the four bevels (12) and the upper bevel fixing beam (14) return to the original position by the force of the spring (13), and are processed. A portable support bender that can take out an iron plate. A portable support bender having a structure in which a caster (17) is mounted under the floor of the fuselage and the operation is freely reduced by reducing the weight of the fuselage according to the four-post structure. The four-post airframe structure according to claim 1 is a structure in which the processing gap can be enlarged according to the size of the processed product. If it is pulled up to the upper end of the four pillars (12) (Fig. 3) and fixed with the tightening screw (16), the gap becomes larger (Fig. 3). Portable support vendor.
