この発明は、ばね製造機における移動部材制御
装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a moving member control device in a spring manufacturing machine.
ばね製造機は、モーターにより複数個のカムを
回転させ、これらのカムの回転により揺動レバ
ー、リンク機構等の公知の動力伝達機構を作動さ
せ、究極的に曲げダイス、ピツチツール、カツテ
イングツール等の工具のスライドを作動するよう
にしたものである。 A spring manufacturing machine uses a motor to rotate multiple cams, and the rotation of these cams operates known power transmission mechanisms such as swing levers and link mechanisms, ultimately producing bending dies, pitch tools, cutting tools, etc. It is designed to operate the slide of the tool.
ところで、ばね製造に際しては、ばねの種類に
応じてそれらのスライドのストロークやそれらの
初期位置の調節をする必要があるが、従来のばね
製造機にあつては、その調節を揺動レバーやリン
クの長さを変更する等の手段により行なうもので
あつたため、その調節が困難であると共に調節に
時間を要し作業能率が悪いという欠点があつた。 By the way, when manufacturing springs, it is necessary to adjust the stroke of the slides and their initial positions depending on the type of spring, but with conventional spring manufacturing machines, this adjustment is done using a swing lever or link. Since this was done by means such as changing the length of the blade, it was difficult to adjust, and it took time to adjust, resulting in poor work efficiency.
この発明は、２個のカムを利用することにより
上記欠点を解消したものである。 This invention eliminates the above drawbacks by utilizing two cams.
以下にこの発明を図面に示す実施例に基づいて

動させられるようになされている。 Two pairs of upper and lower feed rollers 3 are provided to feed the wire rod W to the front surface of the front wall 2 of the spring manufacturing machine 1, and three sets of wire guides 4 are provided to guide the wire rod W fed by these feed rollers 3. It is provided on the front wall 2. A wire rod processing section (wire rod processing space) 5 is formed in front of the left wire guide 4. Bending die 6 facing the left line guide 4
The bending die 6 is attached to a slide 7 which is attached to the front wall 2 so as to be movable left and right, and the slide 7 is urged by a spring (not shown) in a direction to abut against a stopper 8. This slide 7 is configured to be moved left and right by a cam 9 and a swing lever 10 when manufacturing a deformable spring. The wire processing section 5 is provided with a core metal 11 and a pitch tool 12. A cutting tool 13 that cuts the wire W in cooperation with the core metal 11 is detachably attached to the slide 14,
This slide 14 is movable up and down with respect to the front wall 2. A connecting rod 15 is pivotally attached to the lower part of this slide 14, and a swing lever 1 is attached to the lower end of this connecting rod 15.
This swing lever 16 is attached to the front wall 2 via a support shaft 17 at the middle of its length, and the right part of this swing lever 16 has an elongated hole 1.
8 is formed, and a pin 20 at the upper end of the sliding rod 19 is fitted into this elongated hole 18. The sliding rod 19 is fitted into a guide member 21 attached to the front wall 2 so as to be vertically movable, and a swinging rod 22 is pivotally attached to the lower end of the sliding rod 19 at the middle of its length. A cam follower 23 is attached to both ends of the cam follower 23, and each of these cam followers 23 has a first cam 24, a second cam 24,
It is in contact with 25. The sliding rod 19 is urged downward by a spring 26 so that the cam follower 23 does not separate from the first and second cams 24 and 25. The first and second cams 24 and 25 are removably attached to first and second cam shafts 27 and 28, respectively, which are rotatably provided on the front wall 2.
The first camshaft 27 is connected to a rotational shaft of a motor (not shown) that controls the rotational position of the first camshaft 27, so that the position of the first cam 24 can be controlled via the first camshaft 27. That is, the first camshaft 2
7 does not rotate all the time, but is rotated only when controlling the stroke of the slide 14 and its initial position. Therefore, instead of the motor, the first camshaft 27 is operated by a manual handle.
Needless to say, it is also possible to rotate the . The second camshaft 28 is configured to be rotated in synchronization with other slides, etc., by a main motor that operates each slide, etc. of the spring manufacturing machine 1. Due to the rotation of the second camshaft 28, the swing rod 22,
The cutting tool 13 is actuated via a sliding rod 19, a swing lever 16, a connecting rod 15, and a slide 14.

が出来る。 Instead of attaching a motor to the first camshaft 27, a gear is fitted to the first camshaft 27, a gear that meshes with this gear is fitted to the second camshaft 28, and the first camshaft 27 is connected to the second camshaft. Make sure to rotate it at the same time as 28. In this way, the first cam 24 also
By rotating the second cam 25 simultaneously, it is possible to give the slide 14 complex and varied movements that cannot be provided by the rotation of the second cam 25 alone.
