Definitions
- the present invention relates to a method for manufacturing a drive plate in which a plate is integrally fixed to an inner periphery of a ring gear.
- the drive plate starts the internal combustion engine in combination with a pinion gear fitted on the rotation shaft of the starter motor.
- a conventional method for manufacturing a drive plate is as follows.
- a flat gear material is curled and both ends are flash-butt welded to form a ring gear material whose inner and outer diameter surfaces and both end surfaces are cut by a single-purpose plate or a lathe.
- special chamfering is performed to produce a ring gear.
- a plate is fitted on the inner circumference of the ring gear, and one or two welding spots, each with a length of about 15 to 25 mm, are subjected to electric welding at 10 to 12 places to secure them, producing a drive plate.
- an object of the present invention is to provide a method for manufacturing a drive plate in which the cutting time and the chamfering processing are eliminated to shorten the processing time. '' In addition, the present invention reduces the frictional resistance between a female die for press-working a ring gear and a work, thereby extending the life of a mold. It is intended to provide a fabrication method.
- a female die having a tapered surface with an opening angle of 20 to L50 ° provided on the inner peripheral edge of the entrance in the press die forging step and having a mirror-finished surface for sliding contact with the workpiece is used.
- the frictional resistance with the ring-shaped contact is reduced, and an arc-shaped surface is formed on the tip of the tooth portion formed on the outer periphery.
- a plurality of caulking projections formed on the inner circumference are inserted into the caulking holes formed in the circular plate, and the inner circumference of the ring-shaped workpiece is inserted. Attach a circular plate.
- a drive plate can be manufactured by press working, and machining time can be reduced since cutting and welding is not performed.
- a tapered surface with an opening angle of 20 to 150 ° is provided on the inner peripheral edge of the inlet and a female die with a mirror-finished sliding surface with the work is used, so that the frictional resistance with the ring-type work is reduced, and the female die
- the life of the mold can be extended to contribute to cost reduction.
- the press die forging step is performed in two steps, and the opening angle of the tapered surface provided on the inner peripheral edge of the entrance of the female die used in the first press die forging step is more The opening angle of the tapered surface provided on the inner peripheral edge of the female die used in the second press die forging process is increased.
- the frictional resistance between the ring-shaped work and the female die in each press forging process is further reduced, and the life of the die such as the female die can be further extended.
- the shape of the caulking hole is made oval, star-shaped, cross-shaped, or the like, so that material flow generated at the time of caulking is obtained. Due to the movement, it is possible to perform a stronger caulking process, and even if vibration or impact acts on the drive plate, the connection between the ring-shaped work and the circular plate is not loosened or separated.
- FIG. 1 is a sectional view of a drive plate manufactured by the method of the present invention.
- FIG. 2 is a block diagram showing a schematic manufacturing process of a drive plate.
- FIG. 3 is a cross-sectional view schematically showing the first breath die forging process.
- FIG. 4 is a cross-sectional view schematically showing a second press die forging process.
- FIG. 5 is a cross-sectional view schematically showing a trimming process.
- FIG. 6 is a cross-sectional view schematically showing a caulking / strain removing step.
- FIG. 7 is a view showing an example of the shape of the caulking hole.
- FIG. 1 shows a cross-sectional view of the drive plate 1 manufactured by the method of the present invention.
- the manufacturing process of the drive plate 1 includes a first press die forging process 101, a second press die forging process 102, and a trimmer. It consists of a mining process 103 and caulking / strain removing process 104.
- a ring-shaped work 2 is subjected to press die forging using a fixed die 11 and a female die 12 as shown in FIG.
- the female die 12 has a tooth forming portion 13 formed on the inner peripheral surface.
- the sliding contact surface between the fixed die 11 and the ring-shaped work 2 of the female die 12 is mirror-finished.
- the ring-shaped workpiece 2 that has passed through the first press die forging process 101 is subjected to press die forging using a fixed die 21 and a female die 22 shown in FIG. I do.
- the female die 22 has a tooth forming part 23 formed on the inner peripheral surface, and the depth of the engraving is set to about 70% of the thickness of the ring-shaped work 2.
- the sliding contact surface between the fixed die 21 and the ring-shaped work 2 of the female die 22 is mirror-finished.
- a protrusion 25 for forming a chamfer on the tooth part 3 formed on the ring-shaped workpiece 2 is formed.
- a recess 26 for forming 8 to 12 crimping projections 5 is formed on the fixed die 21 from the boss 4 formed on the ring-shaped workpiece 2.
- the ring gear 41 manufactured through the above steps is turned upside down to form a tooth profile 42 on the inner periphery of the die 43.
- the caulking projection 4 a of the ring gear 41 is inserted into the caulking hole 46 formed in the circular plate 45, and the center guide pin 47 is inserted through the center hole 48 for positioning.
- Caulking punch 4 9 The drive plate 1 is manufactured by pressing and crushing the female projection 4 a and fixing the circular plate 45 to the inner periphery of the ring gear 41.
- distortion generated in the tooth profile 42 of the ring gear 41 during the induction hardening is removed.
- the caulking projections 4a are crushed, and the material flows in the caulking holes 46. Therefore, in the above embodiment, as shown in FIG. 7, by forming the shape of the caulking hole 46 into an oval, a star, a cross, or the like, the thickness of the caulking projection 4a is reduced. It is possible to apply even stronger caulking to all corners of 46. Therefore, even if vibration or impact acts on the drive plate, the coupling between the ring gear 41 and the circular plate 45 is not loosened or separated.
- ring gear 41 and the circular plate 45 can be fixed using a rivet.
- the opening angle of the tapered surface formed at the inner peripheral edge of the female die entrance in each press working process is the optimal angle within the range of 20-150 ° depending on the material and thickness of the ring-shaped work.
- a drive plate for starting an internal combustion engine in combination with a pinion gear fitted to a rotation shaft of a starter motor can be implemented by an existing breathing machine. It is possible to cope with the production of many kinds and small quantities only by replacing the main parts such as, etc., and it becomes possible to automate each manufacturing process.
