The guide plate 21 moves away from the bottom of the feed hopper 11 under the action of the driving rod 25, so that the spring that enters the furnace body 1 later falls directly into another heating chamber 12. After the last spring falls, the driving rod 25 drives the guide plate 21 to move back to its original position, and this is repeated, thereby completing the work of separately introducing two adjacent springs into the two heating chambers 12, reducing the probability of springs stacking in the furnace body 1.

[0039] Reference Figure 2 and Figure 3When the size of the spring changes, the movement range of the guide plate 21 needs to be adjusted.

[0040] Reference Figure 1 and Figure 2 The springs after tempering in the heating chamber 12 are accumulated at the bottom of the furnace body 1. A discharge port 13 connected to the bottom of the furnace body 1 is provided on the side wall of the furnace body 1.

A display 47 is fixedly installed on the outer wall of the furnace body 1, and the display 47 is electrically connected to the photoelectric counter 46.

[0044] The working principle of Example 1 of the present application is: When two adjacent springs enter the furnace body 1 in sequence through the feed hopper 11, the spring that enters the furnace body 1 first moves to the guide plate 21, and the guide plate 21 guides the spring so that the spring moves along the inclined plate surface and enters a heating chamber 12. Then the drive motor 24 starts to drive the drive wheel 23 to rotate, and the rotation of the drive wheel 23 drives the drive rod 25 to move in a circular motion, and the circular motion of the drive rod 25 drives the guide plate 21 to reciprocate in the horizontal direction. The guide plate 21 moves away from the bottom of the feed hopper 11 under the action of the drive rod 25, so that the spring that enters the furnace body 1 later falls directly into the other heating chamber 12. After the latter spring falls, the drive rod 25 drives the guide plate 21 to move back to its original position, and this is repeated, thereby completing the work of separately introducing the two adjacent springs into the two heating chambers 12, reducing the probability of springs stacking in the tempering furnace.

[0045] Example 2 Reference Figure 2 and Figure 4 The difference between this embodiment 2 and embodiment 1 lies in the difference in the guide mechanism 2, and three heating chambers 12 are arranged in the furnace body 1 in this embodiment 2, and the three heating chambers 12 are arranged as a first chamber 14, a second chamber 15 and a third chamber 16, and the second chamber 15 is located directly below the feed hopper 11 and between the first chamber 14 and the third chamber 16.

[0046] Reference Figure 2 and Figure 4 The guide mechanism 2 includes two separation plates 51 and a moving assembly 52. ​​The two separation plates 51 are horizontally slidably installed in the furnace body 1. The two separation plates 51 are both in an inclined state, one end of the two separation plates 51 is close to the bottom of the feed hopper 11, and the other ends of the two separation plates 51 are respectively close to the first chamber 14 and the third chamber 16, and the distance between the top ends of the two separation plates 51 can allow the spring to pass. The moving assembly 52 is arranged on the furnace body 1 and is used to drive the two separation plates 51 to move horizontally.

[0047] Reference Figure 4 and Figure 5 The moving assembly 52 includes a moving disk 53, a moving motor 54, a moving block 55, a moving column 56 and two moving rods 57. The moving disk 53 is rotatably mounted on the inner wall of the furnace body 1.

[0049] Reference Figure 2 and Figure 4 The two separation plates 51 move to disperse the springs entering the furnace body 1 into the three heating chambers 12. Compared with the design of two heating chambers 12, the second embodiment increases the time interval for the springs in a single heating chamber 12 to fall in, making it more difficult for the springs in the heating chamber 12 to stack.

[0050] Reference Figure 4 and Figure 5 , a rotating assembly 6 is provided on the moving block 55, and the rotating assembly 6 is used to drive the two moving rods 57 to rotate.

The fourth bevel gear 64 is fixedly connected to the rotating rod 61 and meshes with the third bevel gear 63.

[0051] Reference Figure 4 and Figure 5 When the size of the spring changes, the spacing between the two separation plates 51 needs to be adjusted. The rotation motor 62 is started to drive the third bevel gear 63 to rotate, the third bevel gear 63 rotates to drive the fourth bevel gear 64 to rotate, the fourth bevel gear 64 rotates to drive the rotation rod 61 to rotate, the rotation of the rotation rod 61 drives the two moving rods 57 to rotate, and the two moving rods 57 rotate to drive the two separation plates 51 to move closer to or away from each other, thereby controlling the rotation motor 62 to achieve the movement of the two separation plates 51.

[0052] The working principle of Example 2 of the present application is: The movement of the two separation plates 51 disperses the springs entering the furnace body 1 into the three heating chambers 12. Compared with the design of two heating chambers 12, the second embodiment increases the time interval for the springs in a single heating chamber 12 to fall in, making it more difficult for the springs in the heating chamber 12 to stack.
