Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool mounting device for a spring making machine. [0002] The following are known as conventional spring manufacturing machines. That is, a machine frame having a vertical front wall, a wire processing space formed in front of the front wall of the machine frame, and a wire passage for guiding a wire fed toward the wire processing space are provided on the front wall. The final wire rod guide, the final wire rod guide, rotatably provided on the front wall on the side opposite to the wire rod processing space, at least a pair of wire rod feed rollers to send out while pinching the wire rod,
It is known that a required number of tool mounting slides are provided on the front wall so as to be able to advance and retreat with respect to a wire processing space (see Japanese Patent Publication No. 64-4858). Disadvantages of the prior art The conventional spring making machine has the following disadvantages. Tool mounting slides should not collide with or interfere with each other and wire feed rollers, etc.
Since it is provided radially on the front wall with the wire processing space as the center, the number of tool mounting slides to be mounted is limited, and only about five tool mounting slides can be provided on the front wall. The number of tools that can be used for machining (that is, the number of tool mounting slides) is limited, and the shape of the spring to be machined is limited. [0004] The present invention employs the following means to solve the above-mentioned drawbacks. According to the first aspect of the present invention, a wire is sent from a final wire guide to a wire processing space, and the wire that has been or is being fed into the wire processing space is provided with a tool that projects into or protrudes into the wire processing space. A tool mounting device for a spring manufacturing machine that manufactures a spring by performing processing, such that the spring is located outside the wire processing space, and one end of the rotation center line faces the wire processing space, A rotating body rotatably provided on a machine frame of a spring manufacturing machine, at least two tool mounting slides slidably provided on the rotating body in parallel with a rotation center line thereof, and a rotating body provided with a predetermined tool; A slide actuating device for actuating the tool mounting slide at the operating position when the mounting slide is located at the operating position. According to the present invention, the following effects can be obtained by the above-described configuration. According to the first aspect of the present invention, since at least two tool mounting slides are provided on the rotating body, the tool mounted on the tool mounting slide is selectively used for spring processing by rotating the rotating body. As a result, the spring working performance of the spring manufacturing machine can be improved. Further, since one slide actuator is provided for at least two tool mounting slides provided on the rotating body, cost can be reduced as compared with a case where a slide actuator is provided for each tool mounting slide. . An embodiment of the present invention will be described below. In this description, “front” refers to the front side of FIG. 1, “back” refers to the back side, “left” refers to the left side in FIG. 1, and “right” refers to the right side in FIG. The spring making machine 1 is provided with a machine frame 2 having a vertical front wall 3, a wire processing space 5 formed in front of the front wall 3 of the machine frame 2, and the spring manufacturing machine 1 is fed toward the wire processing space 5. A final wire guide 8 which has a wire passage through which a wire to be passed passes and which is detachably provided on a mount 7 protruding from the front wall 3, and a front end of the final wire guide 8 which is opposite to the wire processing space 5. Rotatably provided on the wall 3,
At least a pair of wire feed rollers 9 for feeding the wire while pressing the wire, and at least one tool mounting device 11 (only one is shown in the drawing) provided on the front wall 3 so as to be located outside the wire processing space 5. (Shown). The rotating shaft 13 of the tool mounting device 11 is
One end is rotatably passed to a gear box 14 having the other end protruding from the front wall 3 and the other end of the rotation center line 12 is directed to the wire processing space 5 side. The rotating shaft 13 is configured to be rotated via a gear 16 by a driving shaft 15 rotated by a motor (not shown). A rotating body 18 is mounted on the rotating shaft 13, and at least two, in this embodiment, three tool mounting slides 19 (see FIG. 3) are mounted on the rotating body 18.
It is slidably provided in parallel with the rotation center line 12. A tool 20 is detachably attached to an end of the tool attachment slide 19 on the wire processing space 5 side. The tool mounting slide 19 is urged by a spring 21 in a direction away from the wire rod processing space 5 to come into contact with a stopper 22 provided on the rotating body 18. The front wall 3 is provided with a slide operation device 24 for operating a tool mounting slide 19 located at an operation position (a position parallel to the front wall 3). The slide actuator 24 is rotatably provided on a bearing 25 provided on the front wall 3 such that the shaft is oriented in the front-rear direction.
6, a swinging lever 27 having an intermediate portion fixed to the support shaft 26 and parallel to the front wall 3, and a longitudinal direction provided at an operating end (left end) of the swinging lever 27 is defined as a left-right direction. , A pair of rollers 29, which are opposed to the ridge 28 from above and below, are provided on each of the tool mounting slides 19, and have an axial center oriented in the front-rear direction, and a driving end of the swing lever 27. It has a known drive device 30 that includes a motor (not shown), a crank mechanism, and the like that swings (right end) up and down. With the above configuration, the rotating body 18 can be rotated to position a desired tool mounting slide 19 of the three tool mounting slides 19 in the operating position. In addition, since the rotating body 18 is rotated in the state of FIG. 1, that is, in a state in which the tool mounting slide 19 contacts the stopper 22, the upper and lower rollers 29 of each tool mounting slide 19 When it reaches a certain position, it naturally faces up and down the ridge 28. In other words, between the movement locus drawn by the upper roller 29 and the movement locus drawn by the lower roller 29 as the rotating body 18 rotates,
That is, an annular groove into which the ridge 28 is fitted is formed. A predetermined gap is formed between the ridge 28 and the roller 29 so as to allow the swing lever 27 to swing. [Modifications and the like] Modifications and the like will be described below. (1) A tool includes all wire processing tools attached to a spring manufacturing machine, such as a bending die, a forming tool, a cutting tool, and a cutting receiving tool. (2) The rotating body 18 may be rotated during the spring manufacturing (during the operation of the spring manufacturing machine 1) or in a preparation stage before the start of spring manufacturing (before manufacturing a predetermined spring). (3) The structure of the slide actuator 24 is arbitrary. Further, a fitting roller whose axis is oriented in the front-rear direction is provided at the working end (left end) of the swing lever 27, and a horizontal groove in which the fitting roller fits is provided in the tool mounting slide 19. Good. Each of the horizontal grooves is positioned in the same virtual horizontal space with the tool mounting slide 19 abutting against the stopper 22 so that the horizontal groove fits into the fitting roller with the rotation of the rotating body 18. Has been done. (4) The tool mounting device 11 can be installed on any known spring manufacturing machine.
