Description

[Detailed description of the invention] This invention relates to an angle ruler that is installed in shearing machines, press brakes, etc., and against which the workpiece is abutted at an arbitrary angle with the processing die.This invention is an angle ruler that improves processing efficiency. Regarding equipment.

Conventionally, when shearing a workpiece using a shearing machine, for example, the side surface of the workpiece was placed against an angle ruler that was adjusted to correspond to the shearing angle of the workpiece relative to the upper and lower blades. Shearing was carried out using

However, when shearing a workpiece that is longer than the upper and lower blades using the feed cutter, the angle ruler is not needed and must be removed, but generally it takes time to remove and install the angle ruler. On the other hand, when shearing a workpiece that is extremely short with respect to the upper and lower blades, the wear of the upper and lower blades does not progress locally and is uniform over the entire length. Another problem is that it is necessary to appropriately move the angle ruler in a direction parallel to the upper and lower blades, which takes time and effort, and as a result, machining efficiency cannot be improved.

This invention was made in view of the above, and its purpose is to provide an angle ruler device that improves machining efficiency.

Examples of this invention will be described below with reference to the drawings. 1 and 2 show an embodiment in which this invention is applied to a shearing machine, where 1 is a shearing machine, 3 is a ram, and 5 is a shearing machine.
9 is a movable blade fixed to the ram 3; 9 is a front table fixed to the machine frame 11; 13 is a T-slot provided in the thickness of the front table 9; 15a to 15c;
is a support that is fixed to the T-slot 13 so that its position can be freely adjusted in the left-right direction, and extends in the front direction. 17a-1
7c is a ruler provided between the clamping surfaces 19 of the supports 15a to 15c and the clamping surface 21a of the shoulder screw 21, as is clear from FIG.
It is provided long in the same direction as the supports 15a to 15c. This is a lock nut as an example of a fixture for fixing the ruler between the clamping surfaces 25 of the supports 15a to 15c. In FIG. 2, since the angle ruler devices 24a to 24c all have the same structure, only the angle ruler device 24a is illustrated.

The ruler bodies 17a to 17c are the supports 15a to 15.
between the clamping surface 19 of the shoulder screw 21 and the clamping surface 21a of the shoulder screw 21, and the lock nuts 23a to 23.
so as to be slidably movable between c and the clamping surface 25,
A predetermined angle θ (for example,
A long hole 27 having an inclination angle of 45° is provided. In addition, 29 is a handle used when sliding the ruler bodies 17a to 17c.

Next, the operation of this embodiment will be described.

Normally, the ruler bodies 17a to 17c are lock nuts 2.
Since 3a to 23c are loosened, they are lowered by their own weight. (Figure 1 reference numbers 17a, 17
(see c). Therefore, when shearing the workpiece by the feed end, all the ruler bodies 17a to 17c may be kept in the lowered state, and there is no need to remove the ruler bodies.

If you want to use ruler bodies 17a to 17c,
Pull the handle 41 and insert the ruler bodies 17a to 17c into the elongated hole 2.
7, then lock nut 23a~
23c (see number 17 in Figure 1).
b), the ruler bodies 17a to 17c are fixed in the raised position. Therefore, the movable blade 5 and the fixed blade 7
When shearing a very short workpiece W, it is sufficient to appropriately raise one of the ruler bodies 17a to 17c, and there is no need to move the ruler.

As described above, according to this embodiment, the ruler body in the angle ruler device can be quickly raised or lowered relative to the abutment surface of the ruler body of the workpiece, so that the setup for shearing by the feed cut can be eliminated. It is easy to do, and there is no need to move the angle ruler device to make the blade wear uniform, and as a result, machining efficiency can be improved.

As can be understood from the above description of the embodiments, the gist of the present invention is as stated in the claims for utility model registration. In a processing machine equipped with a processing position extending in the left-right direction to shear the workpiece in the left-right direction, supports extending in the front direction orthogonal to the shearing direction of the workpiece are placed at multiple locations on the front table. The ruler body is provided on the side surface of each support body so that its position can be adjusted in the same direction as that of the support body, and each ruler body is provided on the side surface of each support body and extends in the same direction as the support body so as to be freely retractable from the top surface. Furthermore, each support is provided with a fixture for fixing the ruler in a protruding state.

Therefore, according to the present invention, by appropriately selecting a plurality of supports to make the ruler protrude,
The processing position in the processing machine can be appropriately selected in the left-right direction, and local wear of the processing position can be prevented. Furthermore, when each ruler is not needed at all, the entire length of the processing position can be used without any problem by releasing the fixing of each ruler by the fixture and recessing it.
