Description

Multistage Pulley Manufacturing Equipment {Manufacturing System for Doubule Pulley}

The present invention relates to a multi-stage pulley manufacturing apparatus, and more specifically, to cut the left and right by half the thickness while rotating the raw material, and the cold forming method so that the left and right sides of the cut to each belt groove Formed to complete, but the incision of the material, it is characterized in that it can be carried out automatically continuously forming.

In general, there are various methods of manufacturing pulleys. In the case of multi-stage pulleys having two or more belt grooves, the shape of the pulley is complicated. It is common to cut and finish the process.

However, when the cylindrical material is manufactured by cutting, it is not suitable for mass production because the processing time per unit product is consumed a lot, and the production cost is relatively high due to the large loss of raw materials due to cutting.

In addition, in the case of cutting after casting, metal structures are different according to casting conditions and parts, and thus durability is reduced, so that it is difficult to produce a uniform product, and the weight of the product is relatively heavy.

On the other hand, in recent years, a method of manufacturing various pulleys by cold forming a pulley material cut in a circular iron plate in order to improve the above disadvantages.

For example, Korean Laid-Open Patent No. 1992-0006053 is a method of manufacturing a one-stage pulley having one belt groove but cold forming by cutting the thickness of the disc material, and also, the domestic patent publication No. 1992 -0006053 and Japanese Patent Application Laid-Open No. 1996-39181 disclose a method of manufacturing a multi-pull by forming a multi-stage belt groove on the outer circumferential surface of a wide circumferential thickness of a disc material and introducing a domestic patent registration. 10-0294736 discloses a method of bending an end of a disc material to one side, cutting the thickness of the disc material, and forming the bent outer circumferential surface by cold forming.

Each pulley manufacturing method as described above is similar to each other in that the belt grooves are formed by cutting and forming the raw material, and the raw material can be saved and the mass production can be performed because there is no cutting process. have.

However, these conventional devices are not suitable for manufacturing multi-stage pulleys that use two or more belts, one for each belt groove.

That is, the single pulley or the multi pulley uses one belt, but the multistage pulley as shown in FIG. 1 uses two or more belts in each belt groove one by one, so that each belt groove must be accurately processed, and the shaft hole is formed. When the left and right balance is made from the disc part, the noise is low and the life is long.

However, the conventional multi-stage pulley manufactured by the above manufacturing method and apparatus for the multi-pulley is not only the material structure of the belt groove to be formed is not dense, the dimensions are not accurate, the cross-sectional treatment is insufficient, and the life of the belt is long. I could not go.

After the second cutting process is finished, the third feed mechanism 045c discharges the disc material from the second cutting process performing means 130 to the next position.

Next is the operation of the forming part 200.

After finishing the cutting part 100, the base material 10 is in front of the first forming process performing means 220 of the forming part 200 in the state of being mounted on another disc material supplying magazine 2 (150). To be prepared.

And the disc material 10 mounted on the disc material supply magazine 2 (150) is sent to the first forming process performing means 220 by the fourth feed mechanism (045d) of the transfer means 2 (240) After the first forming process is finished in the first forming process performing means 220, the second forming process is sent back to the second forming process performing means 230 by the fifth conveying mechanism 045e. After the process is completed and the multistage pulley is completed, the sixth transfer mechanism (045f) is moved for the next process (packing, etc.).

That is, in the first forming process implementing means 220, the first and second dies 3 223 and 227 for the primary molding material as shown in FIG. As the primary gripping portion 10e, as shown in Fig. 5, as the upper and lower dies rotated, the first molding tool 229 having a pair of spare belt groove forming portions 229a is used. Pressurize, but press until the inner diameter of the cylindrical portion generated due to the thickness incision reaches the cylindrical surfaces 223a and 227a of the upper and lower dice 3 (223) and 227, and the left and right cylindrical portions are The belt groove is to be molded.

Subsequently, it is passed to the 2nd forming process execution means 230 by the 5th conveyance mechanism 045e.

In the second forming process performing means 230, the guide material 233a (circumferentially as shown in FIG. 6) of the original material 10 which has undergone the preliminary belt groove forming process in the first forming process performing means 220 ( A pair of the upper and lower dice 4 (233, 237) is rotated by the upper and lower dice 4 (233, 237) for forming the belt belt groove having the size 237a, and the upper and lower dice 4 (233, 237) are rotated. Pressurized using a fourth molding tool 239 having a belt groove forming part 239a of the upper and lower dies 4 (233) (237). Press molded until it reaches the guide portion 233a (237a) of the) to complete the multi-stage pulley product.

Thereafter, it is discharged to the next step by the sixth transport mechanism 045f.

Example 2

An important point in Embodiment 2 is to install only one of the cutting part 100 or the molding part 200, and then install only the upper and lower dies required by each implementing means to collectively produce the entire quantity to be produced. The cutting operation is performed, and then the molding means is collectively produced to produce a multistage pulley.

For example, as shown in FIG. 10, only the cutting part 100 is provided.

In this case, both the primary material 10 of the quantity to be processed is cut through the first cutting process performing means 120 and the second cutting process performing means 130 of the cutting part 100.

Subsequently, the upper and lower dice holders 1 and 122 of the primary cutting process execution means 120 are used to perform the primary forming process to be used in the primary forming process implementation means 220. 3 (223, 227) (see the configuration in Fig. 5), the second die cutting process means 130, the upper and lower die holders 2 (132, 136) of the second forming process performing means ( After attaching the upper and lower dice 4 233 and 237 for the second forming process used in 230 (refer to the configuration in FIG. 6), the first forming process and the second forming process are performed, respectively. In this way, it is possible to produce the finished multi-stage pulley by performing the cutting and forming work separately.

In addition, the first conveying mechanism 045a, the second conveying mechanism 045b, and the third conveying mechanism 045c of the conveying means 1 140 provided in the cutting part 100 have their respective clamping fingers ( 049) to adjust the inner diameter so as to serve as the fourth feed mechanism (045d), the fifth feed mechanism (045e), and the sixth feed mechanism (045f), respectively, behind each die. Of course, the idle roller 060 is to be replaced by a roller suitable for the die of the front portion to be a smooth operation.

This is very appropriate when the installation site is small and the investment for the facility is not sufficient.

Example 3

In Example 3, the first cutting process execution means 120, the second cutting process execution means 130, the primary forming process execution means 220, and the second forming for manufacturing the multi-stage pulley Process implementation means 230, but in order to perform the entire process in one system without separating the cutting part and the molding part to produce a multi-stage pulley completed at once.

The configuration of the third embodiment is configured as shown in FIG.

One mounting table 3 310 for the whole installation, the first cutting process execution means 120, the second cutting process execution means 130, the first forming process execution means 220, and the first The secondary forming process is carried out by means 230, and the transfer means 3 (340).

The mounting table 3 310 includes a first cutting process performing means 120, a second cutting process performing means 130, a first forming process performing means 220, and a second forming process performing means.
