The work collecting mechanism 160 is provided on the front side of the high-frequency heating coil 140 as shown in FIG. Therefore, the axial work W is collected on the front side of the horizontal multi-axis quenching apparatus.

The slide block 161 moves along a guide rail 163 provided from the front side to the back side of the horizontal multi-axis hardening device. That is, the slide block 161 is
Is connected by a connecting member 166 to a slide drive unit 164 which is a cylinder installed below the base 165 provided with the, and slides in accordance with the operation of the slide drive unit 164.

A bolt 165B as a projection is attached above the. The bolt 165B comes into contact with the work collection guide 162 that has been slid to the rear side, and displaces the work collection guide 162 from a horizontal state to an inclined state. By adjusting the degree of screwing of the bolt 165B, the degree of screwing of the work collection guide 162 can be appropriately changed. In addition, the base 16
5 has a pair of side walls 1 having upper ends substantially at the same angle as the inclined work collection guide 162.
65C is provided (in FIGS. 7 and 10,
Only the side wall 165C on the back side of the drawing is shown to show the internal structure of the work collection mechanism 160).

The first quenching unit 100 is configured as described above. On the other hand, the second quenching section 200 is
The first quenching unit 100 has the same configuration as that of the first quenching unit 100 and is located on the left side when viewed from the front.

The operation of the above-described horizontal multi-axis quenching apparatus will be described. In the following description, only the operation of the first quenching unit 100 will be described, but it is assumed that the second quenching unit 200 also performs the same operation as the first quenching unit 100. First, an axial work W to be subjected to induction hardening is supplied to the work supply mechanism 120. At this time, the angle 122 is in an extended state.

The axial work W supplied to the work supply mechanism 120 rolls on the work supply guide 121 and moves to the tip end of the work supply guide 121. At this time, since the angle 122 is in an extended state, the axial workpiece W is
It fits into the concave portion 124 between the work holding claw 122A and the work supply guide 121.

V block 111 of work lifting mechanism 110
But it rises from the workpiece heating position P ₂ to the work supply position P _1. Then, the axial work W is moved to the work supply mechanism 120.
To V block 111.

When the axial work W moves to the V block 111, the angle driving unit 12 of the work supply mechanism 120
3 moves the angle 122 backward. V-block 111 is lowered in this state, the shaft-like workpiece W workpiece heating position P ₂
Move to At this time, since the cooling jackets 150 are provided at intervals larger than the width of the V block 111, the cooling jacket 150 does not hinder the vertical movement of the axial work W.

The axial work W moved to the work heating position P ₂ , that is, the axial work W positioned between the heating conductors of the high-frequency heating coil 140 is moved to the two centers 131 B, 132 B of the work rotation support mechanism 130. Support. V-block 111, so as not to inhibit the rotation of the shaft-like workpiece W by the workpiece rotation supporting mechanism 130, the workpiece heating position P ₂ is a position lowered from the downwardly slightly center center. High-frequency heating is performed on the axial work W rotated by the work rotation support mechanism 130. here,
The reason why the axial work W is rotated during the high-frequency heating is to perform uniform high-frequency quenching on the axial work W.

When the high frequency heating is completed, the cooling liquid L is jetted from the cooling jacket 150 to the axial work W, and the axial work W is cooled, thereby completing the high frequency quenching. Note that the shaft-shaped work W is rotated while the cooling liquid L is being sprayed.

When the induction hardening of the axial work W is completed as described above, the two centers 131B,
132B separates from the axial work W and places the axial work W in the V groove of the V block 111.

V block 11 which has received the axial work W
1 rises from the workpiece heating position P ₂ to the workpiece collection position P _3.

The work collecting mechanism 160 inserts the collecting claw 162A of the work collecting guide 162 below the axial work W supported by the V block 111 by moving the slide block 161 to the back side. Then, the slide block 161 comes into contact with the bolt 165B and is displaced from the horizontal state to the inclined state (see FIG. 10). The displacement of the work collection guide 162 causes the V block 111
The work W supported by the work is collected by the work collection guide 16.
2 and the axial work W is moved to the work collection guide 162.
And the side wall 165C to be collected into a work stocker (not shown).

One shaft-shaped workpiece W that has been subjected to induction hardening
Is recovered by the work collection mechanism 160, the slide block 161 of the work collection mechanism 160 slides from the back side to the front side to return, and prepares for collection of the next axial work W.

In the above-described embodiment, the first quenching unit 100 and the second quenching unit 200 are simultaneously operated. However, the horizontal multi-axis quenching device according to the present invention is not limited to this. . That is, since the first quenching unit 100 and the second quenching unit 200 are independent of each other, they need not be operated at the same time. Accordingly, it is sufficiently possible to operate only the first quenching unit 100 while the second quenching unit 200 is at rest, and vice versa.

The first quenching section 100 and the second quenching section 20
A value of 0 means that the same axial workpiece W can be processed, or that different axial workpieces W, for example, axial workpieces W having different lengths can be processed. This is because the drive-side head 131 and the driven-side head 132 constituting the work rotation support mechanism 130 are each
This is because it is configured to be movable by C and 132C.

Further, by replacing the high-frequency heating coil 140 of each of the quenching sections 100 and 200 with an appropriate one, it is possible to perform high-frequency quenching not only on the length but also on the axial work W having a different thickness. It is. Thus, the first quenching part 10
When performing induction hardening on different axial workpieces W in the 0 and second quenching sections 200, the first quenching section 100 and the second quenching section 200 are independent because the heating time and the cooling time are different. It becomes very important to operate.

In addition, when the driven head 132 of the first quenching unit 100 and the driving head 231 of the second quenching unit 200 are removed from the frame 300, the driving head 131 of the first quenching unit 100 and the second head 231 are removed. The driven side head 232 of the quenching part 200 is opposed to the driven side head 232, and it is possible to support a longer axial work W. In this case, by replacing the high-frequency heating coil 140 or the like with an appropriate one, various types of high-frequency hardening can be performed on the shaft-shaped workpiece W.
Can be applied to In this case, the driving side head 231 and the driven side head 232 of the second
Need to be provided in reverse to that shown in FIG.

In the above-described embodiment, the first quenching section 1
Although a horizontal multi-axis quenching device in which two quenching portions of the second quenching portion 200 and the second quenching portion 200 are arranged in the horizontal direction is taken as an example, the present invention is not limited to this. For example, three quenched portions may be arranged in the horizontal direction.

The work collection mechanism is for collecting a shaft-shaped work that has been subjected to high-frequency hardening from a work lifting mechanism at a work collection position, and includes a work collection guide that is tiltably attached to a slide block. A slide drive unit that slides the slide block along the guide rails. When the slide drive unit approaches the work collection position most, the work collection guide is tilted and moved to the work collection position. 3.
