DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Example:

[0028] like Figures 1 to 6As shown, this embodiment provides a high-strength and toughness spring steel heat treatment device, including a protective shell 1, a rotating seat 2 is provided at the bottom of the protective shell 1, a rotating head 3 is rotatably connected to the rotating seat 2, a circular rotating plate 4 is coaxially connected to the upper end of the rotating head 3, and the lower end of the rotating head 3 is coaxially connected to the driving rod of the motor below the protective shell 1, a fixed column 5 is provided in the middle of the top of the rotating plate 4, and a heating component 6 is evenly arranged on the fixed column 5 from top to bottom, and a plurality of sliding grooves A7 are evenly arranged along the circumference of the top of the rotating plate 4, and the length of the sliding groove A7 is square. In the radial direction of the rotating plate 4, each sliding groove A7 is slidably connected with a mounting rod 8 along the vertical direction, and the lower end of the mounting rod 8 is slidably connected to the sliding groove A7. The side of the mounting rod 8 facing the heating component 6 is evenly provided with sockets 9 from top to bottom, and a mounting frame 10 for placing a spring can be installed and removed from the sockets 9. A locking assembly 11 is provided at the lower part of the mounting rod 8, and the locking assembly 11 is used to fix the position of the lower end of the mounting rod 8 on the sliding groove A7. An opening 12 is provided on the front of the protective shell 1, and a sealing door 13 is hinged on the opening 12.

[0029] According to the number of springs to be processed, a suitable number of mounting brackets 10 can be installed on the mounting rod 8. According to the heating requirements of the springs, the distance between the mounting bracket 10 and the heating assembly 6 can be changed by adjusting the position of the lower end of the mounting rod 8 in the sliding groove A7. The adaptability is good and the adjustment is flexible. The motor drives the rotating plate 4 to rotate through the rotating head 3, so that the mounting rods 8 on the rotating plate 4 can be rotated to the opening 12 of the protective shell 1 in turn, which is convenient for the staff to take and put the springs from the mounting brackets 10 of each mounting rod 8, thereby improving the work efficiency.

[0030] Furthermore, the mounting frame 10 includes an insert plate 14, a support plate 15 and a limit rod 16. The shape of the insert plate 14 is equivalent to that of the socket 9. The shape of the support plate 15 is L-shaped. The upper end of the insert plate 14 is connected to the upper end of the support plate 15. A limit rod 16 is vertically provided on the top of the lower end of the support plate 15. The socket 9 is inclined downward from the side close to the heating component 6 to the side away from the heating component 6. When the insert plate 14 is inserted into the socket 9, the top of the lower end of the support plate 15 is on a horizontal plane, and the top of the lower end of the support plate 15 is supported on the bottom end of the spring, and the spring is sleeved on the limit rod 16.

[0031] When the spring is heat treated, compared with the general vertical hanging spring fixing method, the fixing method of holding the lower end of the support plate 15 horizontally and limiting the limit rod 16 in the middle has a smaller deformation of the spring, improves the uniformity of the whole spring, and makes the spring easy to take and put. The outer end of the socket 9 is high and the inner end is low, and the insertion plate 14 can be stably retained in the socket 9 under the action of gravity, reducing the probability of the mounting frame 10 accidentally falling off from the socket 9.

[0032] Furthermore, the locking assembly 11 includes a transverse plate 17 and a latch 18. The rotating plate 4 is provided with a transverse plate 17 on both sides of the sliding groove A7. The transverse plate 17 is evenly provided with through holes A19 along the length direction. The lower part of the mounting rod 8 is provided with a through hole B20 corresponding to the through hole A19. The position of the lower end of the mounting rod 8 on the sliding groove A7 is fixed by inserting the latch 18 into the overlapping through holes A19 and B20.

[0033] When the installation rod 8 needs to be moved, the latch 18 is pulled out, the installation rod 8 is moved to a predetermined position, and then the latch 18 is inserted into the overlapping through hole A19 and through hole B20 to fix the position of the installation rod 8.

[0034] Furthermore, the heating assembly 6 includes a connecting block 21, a connecting rod 22 and a heating tube 23. The fixed column 5 is evenly covered from top to bottom with a plurality of annular compositions consisting of connecting blocks 21 and heating tubes 23 alternately connected. A connecting rod 22 is connected between the connecting block 21 and the fixed column 5.

[0035] Heat is evenly distributed in the circumferential direction through the heating tubes 23 so that the springs on the mounting frame 10 around the fixed column 5 are evenly heated. The connecting block 21 is connected to the fixed column 5 through the connecting rod 22, thereby fixing the height of the heating tubes 23 connected to the connecting block 21.

[0036] Furthermore, support seats 24 are evenly arranged along the circumference of the bottom of the interior of the protective shell 1 below the outer edge of the rotating plate 4 , and support wheels 25 are rotatably connected to the support seats 24 , and the support wheels 25 are in rolling contact with the bottom of the rotating plate 4 .

[0037] The support seat 24 and the support wheel 25 are used to share the pressure on the rotating plate 4, reducing the probability of the rotating plate 4 being deformed by pressure. The support wheel 25 rolls against the bottom of the rotating plate 4 to reduce the friction between the rotating plate 4 and the support wheel 25, so that the rotating plate 4 driven by the motor can rotate more smoothly.

[0038] Furthermore, a top plate 26 is coaxially connected to the top of the fixing column 5 , a sliding groove B27 corresponding to the sliding groove A7 is provided at the bottom of the top plate 26 , and the upper end of the mounting rod 8 is slidably connected to the sliding groove B27 .

[0039] The sliding groove A7 and the sliding groove B27 are used together to guide the upper and lower ends of the mounting rod 8, thereby preventing the mounting rod 8 from being offset and affecting the normal placement of the mounting frame 10 and the spring.

[0040] Further, the upper and lower ends of the mounting rod 8 are respectively provided with a slider 28, and the slider 28 slides along the sliding groove A7 or along the sliding groove B27. The upper and lower ends of the mounting rod 8 are respectively slidably connected with the sliding groove A7 or the sliding groove B27 through the slider 28.

[0041] Furthermore, an annular groove 29 is provided at the top of the interior of the protective shell 1, the central axis of the annular groove 29 coincides with the central axis of the top plate 26, and hanging blocks 30 are evenly provided along the circumference of the outer edge of the top of the top plate 26, and the hanging blocks 30 are slidably connected to the annular groove 29.

[0042] The annular slide groove 29 and the hanging block 30 are used in combination to guide the rotation of the top plate 26 , thereby improving the stability of the top plate 26 when it is driven by the fixed column 5 to rotate.

[0043] Furthermore, support columns 31 are evenly arranged along the outer edge of the bottom of the protective shell 1 .

[0044] The working principle and use process of this utility model:

[0045] The staff turns the sealing door 13 open, starts the motor, and the motor drives the rotating plate 4 to rotate through the rotating head 3, so that each installation rod 8 stops at the opening 12 one by one. The staff operates the installation rod 8 stopped at the opening 12, first removes the latch 18, pulls the installation rod 8 to the opening 12, installs a suitable number of mounting frames 10 on the installation rod 8, and then puts springs on the mounting frames 10, then pushes the installation rod 8 inward to a suitable position, and finally inserts the latch 18 back to fix the position of the installation rod 8 on the sliding groove A7. After completing the operation of all the installation rods 8, the sealing door 13 is closed, and the heating tube 23 is started to heat treat the spring. After completing the heat treatment of the spring, the sealing door 13 is opened, and each installation rod 8 stops at the opening 12 one by one. The staff operates the installation rod 8 stopped at the opening 12, removes the latch 18 and pulls the installation rod 8 to a position close to the opening 12, removes the spring from the mounting frame 10 of the installation rod 8, and closes the sealing door 13 after removing all the springs.
