JPS5882641A - Double u angle steel fixing device - Google Patents

Abstract

PURPOSE:To prevent a vibration caused by the chatter from occurring during processing while strongly fixing double U angle steel, by fixing the upper flange of the double U angle steel travelling on a roller with a vice and by positioning and supporting the lower flange. CONSTITUTION:The upper flange 20 of double U angle steel 5 placed on rollers supported on roller frames 14, 15 is fixed with vices 3, 3. Between the rollers, a slide sleeve 10 equipped with a set plate 9 on the tip of said sleeve slidably provided on the roller frame 15, and an adjusting plate 11 guided by a guide bar 13 is connected to a slide screw 12 supported on the slide sleeve 10 and the roller frame 14. By turning a handle 18, the screw 12 is turned to permit the plate 11 to hit the lower flange 21, causing the sleeve 10 to slide to permit the plate 9 to put the lower flange 21 therebetween and support it.

Figure 1 is a front view of the entire H-beam processing machine, and Figure 2 is a perspective view of the machine to be machined, with 1ri machining mechanism, 2 a rail, 3 a vise, 5 an H-beam that can be machined, and 6 an H-shape steel. The rollers used to move the section steel 5, 7 are the machining slopes of the upper and lower 7 rungs of the H section steel, and 8 is the processing recess of the web.
When machining, simply fix both sides of the upper 7 ranks of the H-beam 5 in a vise 3, and place and support the lower flange "FiMi" on the row 26, which is pivotally supported at both ends by a pair of roller holders. Then, the machining slope 7 and the machining section 8 were being machined.

However, when machining four parts 8 or long H-beams,
Since the structure makes it difficult to fix the workpiece in a way that reliably prevents vibration, it has the disadvantage that the cutting blade is often worn and broken.

It is an object of the present invention to provide an H-shaped copper fixing device that eliminates such drawbacks, reduces the wear and tear of cutting blades, and fixes workpieces so that machining can be carried out at a high and low cost. .

In the present invention, a processing machine is provided which is movable by engaging with the layer, and the upper 7 flanges of the H-section steel are fixed with a vise, and the lower 7
An H-shaped steel processing machine with a structure in which the lower surface of the flange is mounted and supported on a roller whose both ends are pivotally supported by a pair of roller holders.
Mtl is provided between the rollers, one end is pivotally supported by the piece 11111K of the roller holder, the other end is provided with a handle, and the middle part is pivotally supported on the other side of the roller holder via a slide sleeve. Slide screen 1. −
an adjustment plate that holds the H-shaped steel from one of the four sides of the lower flange by engaging a screw provided on one end of the slide screw, and an inner end of the slide sleeve. This is characterized by the provision of a set plate that is fixed and presses down from the other side of the lower flange of the H° section steel.

Hereinafter, one example of the present invention will be explained based on the drawings. Fig. 3 is a front cross-sectional view of the H-shaped H41m1 fixing device d of this shaft light, Fig. 4 is a normal IjtJ drawing that also explains the fixing means for the H-beam steel, and Fig. 5g6 is a front sectional view of the H-shaped H41m1 fixing device d of this shaft.

17 is a slide screw so that rotation is fixed together with the handle 18; -1Zvc&a set sleeve which is cut out and extends around the slide sleeve 10; 19 is a lock lever 1 provided on the sleeve holder 15 to fix the movement of the slide sleeve 10; :(20 is the upper flange of H-shaped steel,
Reference numeral 21 denotes a lower flange, and the H-shaped steel fixing device of this embodiment is installed between the rollers 6 of a conventional H-shaped porcelain processing machine.

That is, the slide screw 12 is provided with one end supported by a roller holder 144C, a handle 18 provided at the other end, and a middle part supported by a sleeve holder 15 via a slide sleeve 10. An adjustment plate 11 and a slide sleeve 1 that engage with a screw provided on one end of L-12 to hold down the H-beam from one side of the lower 7 flange 21.
A set plate 9 is fixed to the inner end of the lower flange 21 and pressed from the other side of the lower flange 21.

To fix the H-beam, first fix the upper 7 flange 20 with the vise 3, then turn the handle 18, place it on the adjustment plate 11, and then fix the lower flange 20 with the vice 3.
1 is pressed down as shown in FIG.
1 is pressed down as shown in FIG. In this case, the movement is carried out within a dry area indicated by the dimension δ, and is carried out in a stone-like manner. By turning the handle 18 roughly and tightening it firmly, and fixing the system slide sleeve 10 to the lock lever 19, the H-shaped steel of the workpiece is securely held at Vc1. It is possible to prevent vibration during machining and reduce wear and breakage of the cutting blade.

As explained above, according to the present invention, it is possible to achieve the practical effect of reducing the wear and chipping of the cutting rjiJ blade and enabling high-precision machining in machining operations using an H-section steel machining machine.
