Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing chips attached to a workpiece such as an extruded aluminum section having a hollow section or a groove-shaped section along its longitudinal direction by cutting with a rotary saw blade. It is.

In addition, in this specification, "workpiece provided with a hollow part or a groove-shaped part"
This refers to not only a single workpiece with a hollow or groove-shaped part, but also a workpiece with two or more workpieces lined up, one workpiece and another workpiece adjacent to it. With the wall,
It includes a workpiece having a shape in which a hollow part or a groove-like part is formed.

Generally, when cutting a workpiece such as an extruded aluminum profile, chips adhere to the cut part of the workpiece, but conventionally, in order to remove the chips, the workpiece is moved from the table. Not only was this a major obstacle to improving work efficiency, but also the removal of chips had to be done manually.
This was a major problem in rationalization.

Therefore, the present invention solves all of the above-mentioned problems and provides a chip removal device devised to efficiently and reliably remove chips adhering to the workpiece. This method makes clever use of the shape of the workpiece itself, and was designed in consideration of the fact that multiple workpieces, such as extruded aluminum sections, are usually cut at the same time.

That is, the present invention provides a stopper for positioning the cutting dimension of the workpiece on a table on which the workpiece is placed, which has a hollow part or a groove-like part extending in the longitudinal direction, and a compressed air jet body that is movable along the stopper. A plurality of through holes are provided in the stopper in the direction of movement of the compressed air ejecting body, and a plurality of through holes are provided in the stopper in the direction of movement of the compressed air jet body, and a hole is inserted through the through holes and the hollow or grooved portion of the workpiece from the cut end of the workpiece. The present invention is characterized in that an opening through which the discharged compressed air is jetted is provided on a surface of the compressed air jetting body facing the through hole to remove chips from the workpiece.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 to 5, a positioning stopper A1 mounted on the table 1 includes a workpiece contact wall 13 having a plurality of through holes 12 through which compressed air passes, and a contact wall 1
It has a U-shaped cross section and is composed of an opposing wall 14 facing the table 1, a connecting wall 15 and a bottom wall 16 that connect the walls 13 and 14, and the tip of the stopper A1 is connected to the guide wall b of the table 1. A long sliding groove 17 is formed perpendicularly to the longitudinal direction of the table top surface a in contact with the table top surface a.

Reference numeral 18 denotes a stopper guide fixed to the opposing wall 14, which guides the stopper A1 to slide along a guide wall b having scales along the longitudinal direction of the table 1.

2 has one end in contact with the workpiece contact wall 13, and the table 1
It is a plurality of workpieces placed on top, and has a hollow portion 26 and groove-shaped portions 27 and 28 extending in the longitudinal direction.

The present invention utilizes these hollow portions 26 and grooved portions 27 and 28 to discharge the compressed air blown out through the through hole 12 from the cut end of the workpiece 2. This is to remove chips adhering to the vicinity of the cut end, and a box-shaped ejector B1 is used as a means for ejecting compressed air, and the ejector B1 is moved along the stopper A1.

In order to blow out compressed air, the blowing body B1 is
A hose 10 for feeding compressed air is attached to the upper wall 9, and a groove-shaped opening 20 is provided on the opposing surface 19 facing the workpiece abutting wall 13 provided with the through hole 12 of the stopper A1. .

In this embodiment, the jet body B1 slides within the sliding groove 17, and a cylinder 21 attached to the connecting wall 15 of the stopper A1 is used as a sliding means for the jet body B1.

Note that if an opening adjusting plate 23 that slides up and down is provided in the opening 20 of the jetting body B1, the height of the opening 20 of the jetting body B1 can be adjusted according to the height dimension of the workpiece 2. can.

Thus, the plurality of workpieces 2 placed on the table top surface a
is brought into contact with the workpiece abutting wall 13 of the stop flange A1, and the workpiece 2 is cut by a rotary saw blade (not shown). As shown by the arrow in FIG. The compressed air reciprocated by the cylinder 21 along the sliding groove 17 of the stopper A1 and ejected from the opening 20 of the ejector B1 moves the ejector B1 to the workpiece abutting wall 13 of the stopper A1. Through the plurality of through-holes 12 provided along the direction, all the hollow parts 26 and groove-like parts 27 and 28 extending in the longitudinal direction of the workpiece 2 are discharged from the cut end. As a result, the chips adhering to the workpiece 2 due to cutting with the rotary saw blade can be blown off with compressed air, and the chips can be reliably removed.

Therefore, in order to remove chips, the present invention does not require any troublesome work such as moving the workpiece, and does not require manual labor, but automatically removes the workpiece while it is placed on the table. It is extremely useful for streamlining the process of removing chips.

Further, the present invention provides a compressed air ejector that blows compressed air discharged from the cut end of the workpiece through the through hole of the stopper and the hollow or grooved part of the workpiece along the stopper. Since it is movable, it is possible to reliably remove chips attached to the workpiece, even if the workpiece is large in width or has multiple workpieces.

Furthermore, the present invention provides an apparatus that further reduces the working time for removing chips attached to a workpiece and improves working efficiency.

That is, as described above, a plurality of workpieces 2 placed on the table top surface a are brought into contact with and aligned with the workpiece abutment wall 13 of the stopper A1, and the workpiece cutting machine is provided so as to be movable forward and backward across the table 1. After cutting the workpiece 2 with the rotary saw blade 25 for cutting, the rotary saw blade 25 retreats to the pre-cutting position as shown by arrow C in FIG. is provided so as to be movable along the stopper A1 in the backward direction of the rotary saw blade 25, as shown by arrow 2, in conjunction with the backward movement of the rotary saw blade 25.

The compressed air jetting body B1 moves along the stopper A1 a little later than the backward movement of the rotary saw blade 25, and the compressed air jetted from the jetting body B1 is transferred to the position immediately after the rotary saw blade 25 retreats. The chips attached to the workpiece 2 are squeezed by passing them through the hollow part 26 and the grooved parts 27 and 28 extending in the longitudinal direction of the workpiece 2 and sequentially discharging them from the cut end of the workpiece 2. -71 air is used to blow away the chips to ensure that they are removed.

As described above, in the present invention, the compressed air jetting body is provided so as to be movable along the stopper so as to be interlocked with the rotary saw for cutting the workpiece, which is provided so as to be able to move forward and backward across the table. Not only are chips adhering to the workpiece automatically removed, but compressed air is blown onto the workpiece at the same time the rotary saw blade that cut the workpiece retreats from the workpiece. There is no wasted time in cutting the workpiece and removing chips, and it greatly contributes to streamlining the series of operations from cutting to removing chips, improving work efficiency and speeding up work. can.
