Description

DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention (1) Field of Industrial Application The present invention relates to a method of manufacturing a friction plate for a clutch and a manufacturing device used in the manufacturing method.

(2) Conventional technology Conventionally, when manufacturing this type of friction plate, a friction material sheet is cut to obtain a fixed-length product, and then the fixed-length product is punched to obtain an annular friction material.
Thereafter, a method is used in which the friction material is bonded to the annular core plate, and the friction material is further subjected to cutting or molding to obtain a large number of oil grooves.

(3) Problems to be solved by the invention However, when the above-mentioned punching process is adopted, the yield of friction material is low at 20 to 40%.
The problem is that it is not economical.

Furthermore, when oil grooves are obtained by cutting, the groove depth tends to be shallow in order to avoid damage to the core plate, which results in poor oil draining and reduced durability due to deterioration of cooling performance. On the other hand, when the oil grooves are obtained by molding, it is necessary to prepare a mold corresponding to the size of the friction plate, which is extremely uneconomical. There are also some problems.

In view of the above, the present invention provides an economical manufacturing method and manufacturing apparatus used in the method that can improve the yield of friction material and obtain oil grooves having the same depth as the thickness of the friction material. The purpose is to provide.

A method of manufacturing a friction plate for a clutch bonded along the circumferential direction of a core plate, which involves friction between a receiving roller and a cutting roller having a number of cutting blades arranged radially at equal intervals on the outer peripheral surface. The friction material tape is fed in, and the friction material segments are sequentially cut out from the friction material tape by the cooperation of the two adjacent cutting blades and the receiving roller, and are held by both cutting blades. The material segment is extruded from between both cutting blades and press-bonded to the adhesive surface of the core plate that rotates in synchronization with the cutting roller.

The present invention also provides a friction plate for a clutch in which a large number of friction material segments are bonded to the adhesive surface of an annular core plate along the circumferential direction of the core plate with oil grooves between adjacent segments. The manufacturing apparatus is provided with a feeding member that feeds a friction material tape between a cutting roller and a receiving roller that rotate with their outer circumferential surfaces facing each other, and the adhesive surface is made to face the outer circumferential surface of the cutting roller. A support base that supports the core plate is disposed around the cutting roller so as to rotate in synchronization with the cutting roller, and the cutting roller has a large number of cutting blades arranged radially at equal intervals on its outer peripheral surface. is provided with two adjacent cutting blades capable of cutting out the friction material segment from the friction material tape and holding the friction material segment in cooperation with the receiving roller; A pressing member is placed between the two cutting blades; a retracted position in which the pressing member allows cutting and holding of the friction material segment; and a forward position in which the pressing member pushes out the friction material segment from between the two cutting blades and presses it against the adhesive surface. It is characterized by being arranged so that it can reciprocate between positions.

(2) Effects According to the manufacturing method described above, friction material segments are sequentially cut out from the friction material tape and bonded to one center plate, so the yield of the friction material is improved.
Further, it is possible to obtain a friction plate having oil grooves having the same depth as the thickness of the friction material between adjacent friction material segments. Furthermore, since it can be easily applied to the manufacture of friction plates of various sizes, it is possible to improve economical efficiency together with the improvement in yield. Furthermore, since the friction material segments are bonded while rotating the core plate, the bonding work can be performed efficiently and the manufacturing cost of the friction plate can be reduced.

The friction material tape 41 is obtained by slitting a friction material sheet, and a reel 46 wound with the friction material tape 41 is disposed near the turntable 5, and a reel 46 is provided with the friction material tape 41 wound thereon. The tip of the guide member 48 provided with the hole 47 is disposed close to the contact portion between the cutting roller 44 and the receiving roller 45 . On the base end side of the guide member 48, a pair of feed rollers 49 as a feed member is disposed adjacent thereto, and the pair of feed rollers 49 feeds out the friction material tape 41 from the reel 46 to pass through the through hole 47 of the guide member 48. The paper is then fed between a cutting roller 44 and a receiving roller 45. In FIG. 4, reference numeral 50 denotes a tension roller that applies a constant tension to the friction material tape 41.

The cutting roller 44 includes a short cylindrical portion 44a, an annular end wall portion 44b existing at the support frame 33 ₂ side end of the short cylindrical portion 44a, and a mounting boss portion protruding into the short cylindrical portion 44a from the center of the annular end wall portion 44b. 44c.

As clearly shown in FIG. 9, the short cylindrical portion 44a is provided with a large number of cutting blades 51 arranged radially at equal intervals on its outer peripheral surface and capable of contacting the outer peripheral surface of the receiving roller 45. The cutting edge is a short cylindrical part 44

The pressing pin 53 presses against the short cylindrical portion 4 due to the elastic force of the spring 54.
At the retreated position where 4a has slid inward in the radial direction, a distance approximately equal to the thickness of friction material segment 3 is formed between the tip end surface of pressing portion 53a and the cutting edges of both cutting blades 51. On the other hand, in the forward position where the pressing pin 53 slides outward in the radial direction of the short cylindrical portion 44a against the elastic force of the spring 54, the tip surface of the pressing portion 53a protrudes from the cutting edges of the cutting blades 51.

A roller support portion 55a of a fixed bracket 55 is inserted into the short cylindrical portion 44a between the rotation axis of the cutting roller 44 and the core plate 2, and a rotation axis parallel to the rotation axis is inserted into the roller support portion 55a. As the cutting roller 44 rotates, the pushing roller 56 constantly slides against the locking portion 53b of one pressing pin 53 to push the pressing pin 53 against the spring 54. The friction material segments 3 held by both cutting blades 51 are pushed out by the pressing pins 53 and bonded to the bonding surface a of the core plate 2 by pressure.

In this case, both cutting blades 5
Since the pressing pin 53 between 1 and 1 is in the retracted position and a feeding force is acting on the friction material tape 41, the friction material segment 3 deforms so as to draw a convex arc toward the end surface of the pressing portion 53a of the pressing pin 53. However, as a result, the friction material segment 3 is reliably held between both cutting blades 51.

The friction material segments 3 are cut out and held in sequence by the cooperation of the two adjacent cutting blades 51 and the receiving roller 45.

This press bonding operation of the friction material segments 3 is performed sequentially on the bonding surface a of the rotating core plate 2, and when the press pins 53 are released from the push roller 56, they are returned to the retracted position by the elastic force of the spring 54.
