 The present invention is installed inside the door frame of the vehicle panel (Panel-Reinforce Side Outer) that serves to strengthen the strength of the door frame, or panel (Side-inner) constituting the inside of the door frame (hereinafter 'inner panel) The present invention relates to an apparatus for cutting a material to manufacture a material, and relates to a material transport and an improvement of a support structure to more precisely cut a material for constituting such an inner panel.

As is well known, a panel such as a reinforcement plate installed inside a door frame of a vehicle to reinforce the strength of the door is usually formed by welding four panels such as the left and right panels and the upper and lower panels on a plane to form a space in the center. The panel in the part that requires relatively high strength in order to reduce the weight while maintaining the strength is composed of thick (or strong material) steel plate. Welding).

In order to manufacture such an internal reinforcing plate, the material is first cut from the material roll supplied in the form of a roll, and the cutting material is cut so that the angle of the cutting part is very precise and there is no deformation, and then it is connected by laser welding.

However, the conventional cutting device in the cutting process as described above did not have a configuration that can smoothly support the material in the process of cutting the material is transferred, the supply of the material between the feed roller and the cutting device for supplying the roll-shaped material Since the block supporting the spring is installed at the bottom to make it smooth, the tip of the material protruding forward of the cutting blade is lowered down and the back of the cutting blade is lifted up. There was a problem that is not cut at a right angle.

The failure of such cutting is that the welding operation is not made smoothly and accurately to produce a defective inner panel, and when mounted on the vehicle, it is weak to shock, which leads to a crucial problem of increasing the damage of the vehicle and the impact of the occupant.

The present invention devised in view of these problems provides a structure that can support the material very firmly in the process of cutting while the material is transported in the cutting device in the state that the cutting of the material maintains a very accurate dimension and shape It is to be made, and thus the welding between the materials to facilitate the purpose to minimize the defect of the inner panel.

The present invention has a configuration in which the cutting device consisting of the upper cutting blade and the lower cutting blade is in close contact with the material while being in close contact with the upper portion of the lower cutting blade, and at the same time the upper cutting blade is lowered on the side of the lower cutting blade When the bar is characterized in that it comprises a configuration that supports the material, the preferred embodiment according to the accompanying drawings in detail as follows.

1 is an overall configuration diagram of a cutting device according to the present invention, Figures 2a, 2b, 2c is a working state diagram showing the cutting device of Figure 1 in detail, Figure 2a is a state diagram before starting the cutting operation, Figure 2B is a state diagram when the cutting operation is started, FIG. 2C is a state diagram after completion of the cutting operation, FIG. 3 is a sectional view taken along the line AA of FIG. 2A, and FIG. 4 is a sectional view taken along the line BB of FIG.

Cutting device 1 of the present invention is the upper cutting blade 10 is configured on the upper portion of the material 100 passing through the feed roller 2 and the lower cutting blade 10 'is formed right next to it, The upper cutting blade 10 is raised and lowered and the lower cutting blade 10 'is configured to be fixed to cut the material 100 by the lifting and lowering of the upper cutting blade (10).

According to the present invention, a lower pad 20 'supported by a spring 3' is installed on a bottom surface of the lower cutting blade 10 ', that is, under the upper cutting blade 10, and the lower pad 20 The upper surface of ') is made to coincide with the upper portion of the lower cutting blade 10' in the state of not cutting.

And the upper side of the upper cutting blade 10, that is, the lower cutting blade 10 'is provided with an upper pad 20, the upper surface is supported by the spring (3), the upper pad 20 in the free state It was fixed with a bolt (21) to be pushed up without falling into, and the lower end was configured to protrude further than the upper cutting blade (10) in the state of not cutting.

And Figure 5 is an exemplary view showing another embodiment of the present invention, according to the configuration of Figure 5, according to the shape of the inner plate to be produced when obtaining a certain shape in the middle of the material (blanking) As a configuration example to suitably apply to, the entire material to be blanked between the one side cutting portion (1a) and the other side cutting portion (1b) consisting of the upper cutting edge 10 and the lower cutting blade (10 '), respectively. The upper pad 20 and the lower pad 20 'installed to receive the elasticity of the springs 3 and 3' as in the gist configuration of the present invention to press the.

Reference numeral 5, which is not described in the drawings, is a conveyor for transporting the cut material.

It looks at the operation of the present invention having such a configuration.

Basically, according to the present invention, the rolled material 100 is supplied to the cutting device 1 by the supply roller 2 and the lower cutting blade fixed while the upper cutting blade 10 of the cutting device 1 descends. The raw material 100 is cut while deviating from 10 '.

According to the present invention, since the material 100 is firmly fixed by the upper pad 20 and the lower pad 20 ′ in this cutting process, the cutting action is precisely performed, and the upper pad 20 simultaneously with the upper cutting blade 10. The upper pad 20 presses the material before the upper cutting blade 10 touches the material 100 while descending).

In this state, the lower pad 20 'and the lower cutting blade 10' are positioned at the lower end of the material 100. In this state, the upper pad 20 presses the material 100 so that the material is completely horizontal. It will be fixed in a state of maintaining.

In this state, the upper cutting blade 10 continues to descend to cut the material 100. The upper pad 20 is lowered further because the lower part is supported by the material 100 and the lower cutting blade 10 '. It is not possible to press the material 100 more strongly as the spring (3) is compressed, and the lower pad (20 ') is also supported by the spring (3'), so that the upper cutting blade (10) is pushed down as the spring descends. Compress (3 ') and ask the material more strongly.

When the cutting is completed, the upper cutting blade 10 and the upper pad 20 are raised to return, and accordingly, the upper pad 20 and the lower pad 20 'compress the springs 3 and 3'. Return to original state while releasing.

5 also works by the configuration of the embodiment as shown in Figure 5 the upper cutting blade 10 is lowered when the cutting is made because the upper pad 20 and the lower pad 20 'serves to hold the entire material to be blanked the same The cutting of the material is made precisely and uniformly.

Therefore, in the present invention, since the upper pad 20 and the lower pad 20 'compress the raw material 100 until the cutting is completed and the return is performed immediately before the cutting of the raw material 100 is performed, the movement of the raw material in the cutting process. Without this, accordingly the upper cutting edge 10 and the lower cutting edge (10 ') is to be able to always make accurate and uniform cutting.

The configuration of the present invention as described above has been described as an example when manufacturing the inner panel to be used inside the door frame of the automobile, but this does not mean that the technical scope to be protected is limited only when cutting the large product. It is a matter of course that is a technical configuration that is commonly applied when cutting or blanking a material to form a vehicle body of other parts of the vehicle, and is within the scope of the scope of the present invention, and in particular, welding steel plates having different thicknesses or materials by welding. It would be a very suitable technology when connected and used.
