Description

{Separate driving module, left and right coil spring molding machine's integrated arbor and upper and lower cutting unit elevation control device}

The present invention relates to an integrated arbor and upper and lower cutting unit lifting control device for a coil spring molding machine with a separate drive module and left and right windings. More specifically, it relates to a server motor including an encoder, which is a sensitive component, by minimizing the shock generated when cutting the coil spring. A separate drive module that prevents malfunction and damage and minimizes interference with interrelated peripheral devices to facilitate space utilization and reduce overall equipment size, thereby reducing manufacturing costs along with efficient design. This relates to the integrated arbor and upper and lower cutting unit elevation control device of a left- and right-hand coil spring molding machine.

In general, a coil spring forming machine is configured so that a coiling unit coils the coil supplied through the feeding unit to form it, and after forming, it is cut by an arbor and a cutting unit and discharged.

Furthermore, the coiling unit is capable of changing positions, and the cutting unit has two upper and lower units with the arbor in between, but the upper and lower positions can be adjusted together with the arbor, so that left-hand (left-handed winding) or right-handed (right-handed) forming is possible. This makes it possible to obtain more diverse types of coil springs.

However, as shown in FIG. 1, the coil spring forming device for both left and right turns according to the prior art that has been used so far includes a handle 220 on the upper part of the plate 200, and an arbor housing 120 that connects and fixes the arbor 100. It is connected and installed through the TM screw 140 so that the vertical position of the arbor 100 can be adjusted by manual operation through the handle 220, and the upper and lower cutting units 300 and 400 are respectively connected to the cutting tool 310 and 410. The screws (330) (430) of the mounted sliders (320) (420) penetrate the cutting links (350) (450) operated by the cutting motors (340) (440) to cut the cutting links (350) (450). ) It is configured to adjust the height and height of the cutting tools 310 and 410 by loosening and tightening the nuts 360 and 460 screwed at the top and bottom.

Therefore, since the height adjustment of the arbor 100 and the upper and lower cutting units 300 and 400 to change the winding direction (left or right) of the coil spring is done manually, it requires a lot of manpower and is very difficult. Not only is it difficult, but as the height adjustment of the arbor (100) and the upper and lower cutting units (300) and (400) are performed independently by hand, it takes a lot of time to set each unit, resulting in a significant decrease in work efficiency. There was this.

Accordingly, the present applicant used Patent No. 10-1043659, “Arbor for left-right coil spring molding machine and vertical positioning device for upper and lower cutting unit” (see Figure 2), so that the coil supplied by the feeding part on the other side of the plate is 2. In the left- and right-hand coil spring forming machine, which is configured to be formed by left or right winding by a coiling unit, and the formed coil spring is cut by an arbor and an upper and lower cutting unit whose position is adjusted up and down according to the winding direction, the arbor (740) and the upper and lower cutting units 750 and 760 are guided by the guide piece 712 of the plate 710 and connected to the cutting base 730 that slides up and down, and the cutting base 730 is It is connected to the nut 714 installed on the upper part of the plate 710 through the screw 732 at the top, and the nut 714 is connected to the motor 716 installed and fixed on the side of the plate 714 to operate the motor. An arbor and upper and lower cutting unit upper and lower position adjustment device for a coil spring molding machine for left and right use, characterized in that the vertical position of the arbor 740 and the cutting units 750 and 760 is adjusted by driving (716). It has been started.

However, according to this structure, there is no problem when manufacturing small springs with a small diameter (wire diameter), but when manufacturing large springs with a large diameter, the entire device becomes larger and the size of the cutting server motor and gearbox module increase, which causes the operation. The vibration (shock) within the device increases, and as a result, the shock is transmitted to the server motor, raising concerns about failure or damage to the server motor, including the encoder, which is a sensitive component.

In addition, because the server motor and gearbox module are attached to a cutting base that moves up and down, the size of the cutting base becomes large, causing interference with interrelated peripheral devices and limitations in space utilization, making efficient design difficult. As the main plate becomes larger, the size of the equipment increases, resulting in an increase in manufacturing costs.
