Abstract

PURPOSE:To obtain the titled device capable of cutting the protruded part of a member having a continuous length mechanically from a predetermined position by a method wherein a cutting blade is swingably attached so that it is separated from the protruded part of the member of continuous length at the upper dead point of the running thereof and is moved to approach the covered part of the member of continuous length as it is moved for running. CONSTITUTION:The member of continuous length M is fixed to and supported by a cradle 2 so as to face the protruded part S upwardly and a swinging plate 5 connected to a ram 6 located at the upper dead point is retreated and swung by the notch 8a of a guide plate 8. A pressing roller 3 and the cutting blade 4 are separated from the member M of continuous length. When a driving cylinder 9 is operated to run and move the ram 6, the plate 5 is swung into a straight line under being guides by the guide plate 8. The roller 3 presses the side surface of the member M, the blade 4 cuts into the protruded part S and the protruded part S is cut along a given length by the horizontal movement of the blade 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for shaving and cutting an elongated member formed of soft rubber or the like over a certain length.

For example, a cushioning material S made of soft rubber or the like as shown in the first diagram.
In order to prevent the molding M from coming into contact with the vehicle body, or to make it possible to connect the frame F with each other by inserting it, a cushioning material S in the form of a protrusion or a flat surface is used.
In some cases, it may be necessary to shave and cut a certain length over two parts (see the two-dot chain line in Figure 1). Conventionally, this type of work was completely done manually, like cutting with a cutter knife. This process is extremely time consuming and extremely inefficient, and also has the disadvantage that the cutting dimensions cannot be kept constant.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cutting device for shaving the seat part of a long leg member, which is configured to mechanically and efficiently perform such work.

That is, in the cutting device according to the present invention, the receiver is arranged so that the cutting knife can be driven to travel along the longitudinal direction of the elongated member that is clamped and placed on the table, and the cutting knife is moved at the top dead center of the travel. The force of the protruding part of the length member is ejected at a distance from the elongated part, and as it travels (
A ridged portion of two elongated members (=a device configured to be swingable so as to move close to each other).

Hereinafter, this will be explained based on the illustrated embodiment.

The cutting device shown in the figure includes a support 2 for sandwiching and mounting the elongated member M on the board surface of a base 1, and a row of presser rolls 3 that are driven to run along the longitudinal direction of the elongated member M at regular intervals. (=It is equipped with a cutting puf 4. The receiver table 2 has a holding plate 2a for the elongated member M to be placed on the plane thereof, and positions and locks the insertion end side of the large elongated member M. Stone/<2b.

Further C: is a clamp 2 that supports the midsection of the elongated member M by holding pressure.
I have c. The presser roll 3 is mounted on the swinging plate 5 by a spring 3a, and the cutting pipe 4 is attached to the four-moving plate 5 using a cutter knife. The receiver is arranged so as to protrude from the swing plate 5 onto the elongated member MIII which is supported by the stand. The swinging plate 5 is swingable on the ram 6 with a support pin 7 (two-connected mounting is provided, and the ram 6 is slidably supported on the left and right sides with a guide plate 8, and is connected to the rod 9a of the drive cylinder 9. (The ram 6 (two-phase shaft-connected swing plate 5 is movably guided by the guide plate 8 together with the ram). However, at the top dead center, the presser roll 3 and the cutting knife 4 are configured to be able to move away from the elongated member M.The mechanism is such that the bottle IO hits the swing plate 5 at the top dead center. is provided protrudingly from the board surface of the base l, and a notch 8a is formed in the guide plate 8 to enable escape when the swinging plate 5 moves apart (see Figure 2). Also,
In addition, an extension spring 11 may be tensioned between the swing plate 8 and the ram 6 (see Fig. 3).

In the shaving cutting device configured in this way, in the case of a long member M such as a molding in which the lip portion where the protruding stripe S exists is integrally molded with a soft resin, the protruding stripe portion S is oriented upward (

place When placing the elongated member M, the distal end side of the elongated member M is placed against the stopper 2b (two stops), and then the holding plate 2
m, fixedly supported by clamping with clamps 2C. When this elongated member is placed, the ram 6 is located at the top dead center, and the swing plate 5 connected to the ram is placed on the bin 1.
0, the presser foot 71-ra 3 and the cutting knife 4 are positioned in the direction C2 apart from the elongated member M. When the drive cylinder 9 is operated to move the ram 6 from this state, the ram 6 (
= Pivotally connected oscillating brace 5 is guided by guide plate 8 (2) and oscillates together with ram 6 to move in a straight line.
The cutting knife 4 presses the side surface of the long member M, and the cutting knife 4 moves close to the long member side to make two cuts (see Figures 4 and 5). When rotating the knife horizontally, it is possible to cut out the protruding portion S by placing the knife edge slightly curved upward, and it is also possible to cut out the protruding portion S by rotating the knife at an angle with a downward slope. After this cutting movement, the cutting knife 4 moves so as to cut horizontally C2 along the longitudinal direction while pressing and locking the protrusion S of the elongated member M with the presser roller 3 (6th cut). (see figure), the horizontal movement is performed simultaneously from the midsection of the elongated member M toward the distal end, and the protrusion S of the elongated member M can be cut over a constant length.

Cutting operation 4P: After completion of the cutting operation, the presser roller 3 and the cutting knife 4 return to their original positions by extending the stroke of the drive cylinder 9, and wait until the next elongated member is inserted. In addition, in the above-mentioned embodiment, the case of cutting the protrusion was explained based on the width.
This device can also be applied to ζ2 when partially shaving the lip portion.

As described above, according to the present invention C: the cutting device according to the present invention.

This makes it possible to mechanically cut the protrusions of a long member from a fixed position, and allows efficient work to be done without causing any chips.
