Description

[Detailed description of the invention] [Industrial application field] This invention has a chip breaker placed in front of the plane body that has the plane blade in order to prevent the material to be cut from lifting up and to prevent it from sticking in the front and rear directions. Regarding the chip breaker of the automatic plane machine.

[Conventional technology]

The above-mentioned conventional chip breaker has a plurality of chip breaker bodies that pass through vertical holes on a support bar installed in a frame, and each of the chip breaker bodies is movable up and down with each vertical hole, and is biased downward by a spring. When cutting the workpiece, the workpiece is forcibly fed by a feed roller and is held down by a spring against the lifting surface plate to prevent it from lifting up.

[Problem that the invention attempts to solve]

However, with conventional chip breakers, small cutting debris such as chips enters the gaps between the chip breakers and the vertical sliding part between each chip breaker and the support bar through these gaps, causing vertical movement. becomes unable to transport materials,
There are problems such as it not functioning as a chip breaker.

The present invention is an attempt to solve the above-mentioned problems.The chip guide has a vertically elongated through hole so that it can be moved up and down, and is biased downward by a spring so that it can be attached to a suitable place such as the rear wall of each chip breaker body. By opening and configuring a cutting waste discharge port, the cutting waste that enters the vertical sliding portion of each chip breaker body during cutting of the material to be cut is released from the discharge port to the outside, The object of the present invention is to provide a chip breaker that prevents the chip breaker body from being inoperable and functions reliably and smoothly to prevent the workpiece from lifting up.

[Means for solving problems]

In an automatic planer chip breaker, which has a planer barrel disposed above the material raising/lowering surface plate, a feed roller provided before and after the planer barrel, and a chip breaker provided between the planer barrel and the front feed roller, a chip guide is provided. Vertical holes are provided in a plurality of chip breaker bodies which are installed on the exterior and can be moved up and down by being biased downwardly by a spring, and a cutting waste discharge port is provided on the opposite side of the plane body to communicate with the vertical holes. By providing this, the above problem was solved.

〔Example〕

Detailed explanation will be given below based on the drawings showing the embodiments of the present invention. As shown in FIG. It is rotatably supported and
A chip breaker 4 and a pressure bar 5 are disposed at the front and rear of the plane body 3 and biased downward by intervening springs 22 and 7, respectively, and the front part of the chip breaker 4 and the pressure bar 5
Feed rollers 8 and 9 are rotatable at the rear of the
The planer barrel 3 and the feed rollers 8, 9 are supported in parallel with the plane cylinder 3, and are driven by a motor (not shown) in the directions of arrows a and b in FIG. 1, respectively.

Further, a cover 10 is attached to the upper part of the frame 1, and is communicated with an opening 11 opened at the upper part of the plane body 3 of the frame 1, and the cutting waste is discharged to the outside through a discharge port 12 provided in the cover 10. It is designed to do so.

Below the frame 1, the plane body 3,
A material elevating surface plate 13 is supported by a guide means 14 so as to be movable up and down, facing the chip breaker 4, pressure bar 5, and feed rollers 8 and 9, and a material feeding path 6 is formed. Although it is provided so that it can be raised and lowered automatically by a lifting device and a drive motor, or manually by rotating an elevator handle (not shown), the automatic lifting means and manual lifting means for the lifting surface plate 13 are provided. Since a known means is used, detailed explanation thereof will be omitted.

Further, on the elevating surface plate 13, a plurality of rollers 15, 16 are provided with the feed rollers 8, 16 so that the workpiece W is smoothly fed on the upper surface of the surface plate.
It is pivoted opposite to 9.

In this way, when the elevating surface plate 13 is automatically or manually raised and the workpiece W is fed through the entrance 1a of the frame 1, the workpiece W is forcibly fed by the feed roller 8, and the workpiece W is moved up and down the elevating surface plate by the chip breaker 4. 13 to prevent the workpiece W from lifting up, and automatically cut the workpiece W with the plane barrel 3. Next, the pressure bar 5 presses the workpiece W downward to prevent it from lifting up, and the workpiece W is pressed against the feed roller 9. Then, forcefully feed it to the opposite side, completing one cycle of cutting.

According to the present invention, the chip breaker 4, which functions to press the workpiece W against the lifting surface plate 13 at the front position of the plane body 3 during cutting, is constructed as follows.

As shown in FIGS. 2 and 3, the chip breaker 4 includes left and right side plates 1b of the frame 1,
1b, a chip guide 20 is fixedly installed with screws 18, 19 through L-shaped brackets 17, 17, and a plurality of chip breaker bodies 21...
and a compression spring 22...

That is, each chip breaker main body 21 is curved into an arcuate surface 21a on the plane body 3 side to facilitate guiding cutting chips toward the opening 11 side, and has a tip guide 20 at a substantially center position thereof. A vertically elongated hole 21b that fits and is slidable in the vertical direction is passed through in the left-right direction, and the tip guide 20 is fitted with the vertically elongated hole 21b so as to be movable up and down, and the lower surface of the tip guide 20 and the bottom surface of the vertically elongated hole 21b are connected to each other. The chip breaker bodies 21 are supported by the chip guide 20 in series in the left-right direction by being biased downward by supporting the ends of the springs 22 and internally interposing them in the longitudinal holes 21b.

On the opposite side of the planer body 3 of each chip breaker body 21, that is, on the rear wall 21c with respect to the material feeding direction, and on the inclined bottom wall 21d formed by tilting downward from the rear wall 21c forward, cutting waste is discharged. Exit 23...
is provided in communication with the longitudinal hole 21b, and during cutting, each chip breaker body 21, 21
The above-mentioned vertical hole 2 from the mutual butt portion 24 etc.
1b and the chip guide 20 portion, in other words, the chip breaker body 21 in such a way that chips and other cutting debris d that have entered the vertical sliding portion of the chip breaker body 21 are discharged to the outside from the discharge port 23.
It is constructed so that vertical movement can be performed smoothly at all times.

[Effect of idea]

As explained above, since the chip breaker of the automatic plane machine according to the present invention is configured, during cutting, the workpiece W is pressed against the surface of the lifting surface plate 13, and moved in front of the plane body 3 in order to prevent it from lifting up. If cutting debris such as chips enters the vertical sliding portion of a plurality of chip breaker bodies 21 that are attached so as to be movable up and down and urged downward by springs 22, the chip breaker bodies 21 Since this can escape to the outside from the discharge port 23 opened on the opposite side of the planer body 3, the vertical movement of the chip breaker body 21 is not blocked by the cutting waste, and the cutting waste is constantly and reliably removed. , and can operate smoothly up and down, allowing it to always function reliably as a chip breaker.
Inability to feed material due to vertical movement being blocked can be avoided, and structurally, each chip breaker body 21
Since the discharge port 23 is simply provided at a suitable location such as on the opposite side of the plane body 3, it is extremely simple and has the advantage of being able to be manufactured at low cost.
