Core manufacturing method for oil filter

The present invention relates to a method of manufacturing a core among components of an oil filter mainly used in automobiles.

According to the conventional method of manufacturing a core, a copper plate wound in a roll shape is cut into a mug at a size at which one core is formed in accordance with a desired core network size, and then transferred to a bending step to bend both ends of the folded side. Then, the transfer to the next step was bent in the U-shape and the two ends are bent by pressing to form a cylindrical core network.

This conventional method is a step of winding the ends of the material (copper plate) continuously fed in the form of a roll to the core size in advance in the first step, and then bending both ends using a conveying means such as a conveyor belt or chain belt, U-shaped Since the work is carried out while transferring several steps such as bending step and pressing step, the upper and lower interlocking portions of the cylinder do not become horizontal as shown in FIG. The interlocking part E is formed up and down as shown in FIG.

Therefore, when assembling the oil filter, the filter paper is installed inside the outer case, and the core is installed again inside the filter paper. Then, the base plate is joined to the upper and lower sides. In addition, since the crimped portion is formed to the upper and lower ends, the center of the circle does not exactly fit into the coupling groove of the base, so that the filtration function of the oil filter is lowered and the reliability of the product is lowered.

An object of the present invention is to make the upper and lower surfaces of the core uniformly horizontal when the core is completed, and another object of the present invention is to prevent the crimping portion of the core from being formed to the upper and lower ends when the core is completed. .

In order to achieve the above object, in the present invention, the copper plate (material) in the form of a roll is not cut in advance but the copper plate is continuously supplied to the final stage. Successively bending both ends between the cutout and the cutout at opposite angles (about 30 °) smaller than 90 ° in the opposite direction, and then cutting, bending, squeezing, squeezing without moving at all in the final step. The following operation is performed simultaneously so that the upper and lower ends of the cylindrical core network is formed horizontally and uniformly, and the crimping portion is not formed to the upper and lower ends, but is not formed by a predetermined length from the upper and lower ends.

Hereinafter, the manufacturing method of the present invention will be described in detail.

The schematic configuration of the mechanical device for achieving the manufacturing method of the present invention is shown in FIG. That is, Figure 1 is a device for achieving the production method of the present invention, the base 20 is installed on the base 2, connected from the base 20, the opposite side of the base and the predetermined height of the base 1 The rail (3) is installed and the guide roller (4) and the cutting device (5) are installed on the rail from the left end, and the cutting device is cut by the pneumatic cylinder (6). By the movement handle 7 can be moved left and right on the rail.

On the right side of the cutting device 5, the bending device 8 is also provided on the rail 3, and the bending device is also bent by the pneumatic cylinder 9, and is moved by the left and right moving handles 10. It can be moved left and right on the rail.

At the base 20 on the right side of the bending device 8, a pulling device 11 is provided toward the bending device 8, and the copper plate (material) is pulled by the motor 12.

The right side of the base 20 is provided with a protruding rod 21 and the various devices are installed around the base 20, as shown in FIG. That is, a material moving groove 22 is drilled on the upper side of the protruding rod 21 and a cutting knife 23 is installed, and a U-shaped bending mold 24 is installed so that the lever 25 and the cam 26 are installed. ) Up and down movement.

Side bending molds 27 and 31 are respectively provided on the left and right sides of the protruding rod 21, and the side bending molds 27 are formed by the sector gear 28, the lever 29, and the cam 30. In the forward movement, the side bending mold 31 moves forward and backward by the sector gear 32 lever 33, 34 and the cam 26.

In addition, the discharge plate 37 is installed in the form of the base 20 in the horizontal direction in the lower direction of the protrusion bar 21, and is moved forward and backward in the longitudinal direction of the protrusion bar by a separate lever, A crimping mold 35 is provided, and the lever 36 and the cam 30 move up and down.

Core manufacturing method for the oil filter of the present invention is as follows.

The manufacturing method of the present invention is made as shown in FIG. That is, the cutting plate 5, the bending device 8, the pulling device 11 through the device guide roller 4 of FIG. Move continuously to). The copper plate A passing through the cutting device 5 is formed with cutouts B at regular intervals on both sides in the longitudinal direction by the cutting device (the intermediate portions of both cutouts are cut later).

The copper plate A having passed through the cutting device 5 is bent at an acute angle of less than 90 degrees in the direction symmetrical to both sides of the cutout portion between the cutout and the cutout while passing through the bending device 8.

The copper plate that has passed through the bending device 8 exits the copper plate moving groove 22 of the base 20 through the pulling device 11, and when half of the cutout portion B formed in the copper plate is pulled out, the pulling device 11 is momentarily pulled out. As the motor 12 of) stops, the copper plate also stops moving. At this moment, as the cutting knife 23 descends by the operation of the cam, the copper plate is cut into the size of a unit in which one core network can be formed. At the same time, the cam 26 and the lever 25 operate to form a U-shaped bending mold ( 24) bends the cut material into a U-shape while descending, and at the same time, the left and right side bending molds 27, 31 bend in a circular shape while moving toward the protruding bar 21, and interlock the bent portions at the same time. The pressing mold 35 is raised to squeeze the engaged portion to complete the core, the operation of which is as shown in FIG. Thereafter, as soon as the discharge plate 37 moves forward as shown in FIG. 4, the finished core is removed from the protruding rod 21, thereby completing the fabrication of the core. This operation is repeated and the core continues to be manufactured while the copper plate is supplied.

In the method of the present invention manufactured as described above, the cutout is formed on the continuously supplied copper plate without cutting the copper plate in advance, and then bent. Then, the cutting operation is instantaneously made into a U-shape. It is characterized by simultaneous work and discharge work.

In the manufacturing method of the present invention, without cutting the roll-shaped copper plate in advance to the size of the core in advance, and forming only the cutout in the position to be cut to the core size and then bending the corners other than the cutout, By cutting, making U-shape, making a circle, joining bent parts, and pressing work to complete the core at the same time, the upper and lower ends of the cylindrical core are formed uniformly horizontally, and the pressing part is formed up to the upper and lower ends. When the oil filter is assembled, the filter paper is installed inside the outer case, and the core is installed inside the filter paper again. Coupling groove of base plate because horizontal, crimped part is not formed up and down The center of the core is precisely combined to facilitate the assembly of the oil filter, improve the filtration function, and improve the reliability of the product.
