Description

[Detailed Description of the Invention] <Industrial field of application> The present invention relates to a safe bender for sheet metal bending, in which the blade width of the upper blade and the gap between the blade and the blade can be arbitrarily changed with a template. It is a thing.

<Prior Art> FIG. 11 is an explanatory view of a main part configuration of a conventional example which is generally used conventionally, and FIG. 12 is a side view of FIG.

In the figure, 1 is a lower blade, 2 is an upper blade, and 3 is an upper blade holder.

As the upper blade 2, generally, a sufficiently long blade is used for general purpose, or an upper blade having a length corresponding to the bending width of the work or a dedicated blade is used.

<Problems to be Solved by the Invention> However, in such a device, (1) it is necessary to replace the upper blade depending on the bending shape of the work. Therefore, it is necessary to perform a stage change work.

(2) When replacing the upper blade 1, there is a problem in safety work because a hand is put under the upper blade 1.

The present invention solves this problem.

An object of the present invention is to provide a bender for sheet metal bending, which can change the blade width of the upper blade and the gap between the blades using a template with one touch, and which is safe for work.

<Means for Solving the Problem> In order to achieve this object, the present invention is a bender for sheet metal bending that bends a sheet metal material to a required angle by using an upper blade and a lower blade. The holder has a plurality of divided upper blades, one end of which is freely slidable in the left-right direction and is finely divided into required unit widths, and an inclined surface which is provided on the divided upper blades and forms a constant angle with the left-right direction. An inclined portion for setting a gap, a stopper provided on the holder of the upper blade and provided on one end of the divided upper blade in the left-right direction, and two guide pins provided on the holder of the upper blade, The setting template guided by the guide pin, and one end fixed to the setting template provided at a required position of the setting template and the other end engaged with the inclined portion to push and move the divided upper blade in the left and right direction. The divided upper blade Is obtained by constituting the sheet metal piece machining vendors, characterized by comprising a projecting portion that sets a required clearance.

<Operation> In the above configuration, a plurality of divided upper blades are arranged in close contact with the stopper in the upper blade holder. Insert the required setting template into the guide pin. When the required setting template is inserted into the guide pin, the tip of the protrusion fixed to the required position of the setting template engages the inclined portion provided on the split upper blade, and the split upper blade with the protrusion engaged. Is moved in the left-right direction to set a required gap at the position where the divided upper blade was.

Hereinafter, detailed description will be given based on examples.

<Embodiment> FIG. 1 is an explanatory view of a main part configuration of an embodiment of the present invention, and a setting template is omitted for easy understanding. Second
1 is a side view of FIG. 1, FIG. 3 is a sectional view taken along line XX of FIG.
FIG. 4 is a plan view of the setting template, FIG. 5 is a side view of FIG. 4, FIG. 6 is a perspective view of FIG. 4, and FIGS. 7 and 8 are operation explanatory diagrams of FIG. FIG. 10 and FIG. 10 are explanatory views of an actual use example of FIG.

In the figure, the same symbols as in FIG. 11 indicate the same functions.

Only parts different from FIG. 11 will be described below.

In the figure, 11 is a holder for the upper blade, and 12 is a plurality of divided upper blades, one end of which is freely slidable in the left-right direction of the figure and is subdivided into required unit widths, as shown in FIG. is there. Divided upper blade 12
In this case, a 5mm width is adopted.

As shown in FIG. 3, reference numeral 13 is an inclined portion for setting a gap, which is provided on the divided upper blade 12 and has an inclined surface 131 that makes a constant angle with the horizontal direction in the drawing.

As shown in FIG. 3, 14 is a stopper provided on the holder 11 of the upper blade and provided on one end of the divided upper blade 12 in the left-right direction.

Reference numeral 15 denotes two guide pins provided on the upper blade holder 11 as shown in FIG.

Reference numeral 16 denotes a setting template guided by the guide pin 15, as shown in FIG.

17 is provided at a required position of the setting template 16, one end of which is fixed to the setting template 16 and the other end of which is engaged with the inclined portion 13, and the divided upper blade 12 is pressed and moved in the left-right direction to generate the divided upper blade.
It is a protrusion that sets a required clearance C between the two.

In the above structure, (1) a plurality of divided upper blades 12 are arranged in the upper blade holder 11 in close contact with a stopper 14 in the left direction in the drawing.

(2) Insert the required setting template 16 into the guide pin 15.

(3) Insert the required setting template 16 into the guide pin 15 as shown in FIG. 7 and FIG.
The tip of the protrusion 17 fixed to the required location of 16 is the divided upper blade.
The divided upper blade 12 engaged with the inclined portion 13 provided on the 12 and the protruding portion 17 is pushed and moved in the left-right direction, and a required gap 18 is set at the place where the divided upper blade 12 was located. To do.

(4) After that, sheet metal bending is performed until the required number is obtained.

(5) When the sheet metal bending work is completed, the setting template
Remove 16.

(6) Place a plurality of divided upper blades 12 on the upper blade holder 11 in close contact with the stopper 14 in the left direction in the figure.

(7) Another setting template 16A required for the guide pin 15
Insert and repeat the above work.

In addition, A and B show works.

Figures 9 and 10 show actual usage examples.

As a result, (1) the blade width of the upper blade 12 and the gap between the upper blades 12 and the upper blade 12 can be arbitrarily changed by one-touch with the required template 16, and the changeover time can be shortened and the manufacturing cost can be reduced.

(2) Since it is not necessary to replace the upper blade 12, work safety can be improved.

Note that in the above-described embodiment, the setting template 16
Although it was described that the setting was made, the setting is not limited to this, and it goes without saying that the setting may be taken out after the setting.

In addition, the width of the divided upper blade 12 may be any width, and may be a combination of objects having different width dimensions.

<Effects of the Invention> As described above, the present invention is a bender for sheet metal bending that bends a sheet metal material to a required angle by using the upper blade and the lower blade, and the holder of the upper blade is folded in the left-right direction. A plurality of divided upper blades having one end movably attached and formed by subdividing into a required unit width, and an inclined portion for setting a gap having an inclined surface provided on the divided upper blades and forming a constant angle with the left-right direction. A stopper provided on the upper blade holder at one end in the left-right direction of the divided upper blade, two guide pins provided on the upper blade holder, and guided by the guide pins. Between the setting template and the dividing upper blades, one end of which is provided at a required location of the setting template and one end of which is fixed to the setting template and the other end of which is engaged with the inclined portion and which moves the divided upper blades in the left-right direction. Set the required gap To constitute a sheet metal piece machining vendors, characterized by comprising a that protrusion.

As a result, (1) the blade width of the upper blade and the gap between the upper blade and the upper blade can be arbitrarily changed by one-touch according to a required template, and the changeover time can be shortened and the manufacturing cost can be reduced.

(2) Since it is not necessary to replace the upper blade, work safety can be improved.

Therefore, according to the present invention, the blade width of the upper blade and the gap between the blades can be arbitrarily changed with one touch using a template, and a safe sheet metal bending vendor can be realized.
