[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0027] The preferred embodiment of the heat treatment device for automobile fasteners provided by the present invention is as follows Figures 1 to 5 The figure shows: a heat treatment device for automobile fasteners, comprising a base frame 5; a controller 4 fixedly connected to one side of the top of the base frame 5; a quenching cylinder 7 fixedly connected to the top of the base frame 5; a feed hopper 1 fixedly connected to one side of the top of the quenching cylinder 7, the bottom end of the feed hopper 1 being connected to the interior of the quenching cylinder 7; a quenching chamber 9 fixedly connected to the surface of the quenching cylinder 7, the bottom end of the quenching chamber 9 being fixedly connected to the top of the base frame 5, and a heating tube 10 fixedly connected to the interior of the quenching chamber 9 at equal angles; through holes 11 arranged at equal intervals on one side of the surface of the quenching cylinder 7; an adjustment component 8 assembled inside the quenching chamber 9, the adjustment component 8 is used to prevent smaller automobile fasteners from falling into the interior of the quenching chamber 9; an anti-blocking component 2 assembled at the upper end of one side of the quenching chamber 9, the anti-blocking component 2 is used to prevent automobile fasteners from being blocked at the lower end of the feed hopper 1; a servo motor 3 fixedly connected to one side of the quenching cylinder 7, the output end of the servo motor 3 extending into the interior of the quenching cylinder 7 and fixedly connected to a spiral feeding rod 6 through a coupling.

[0029] It should be noted that the existing heat treatment device for automobile fasteners still has certain shortcomings during actual use. Since the aperture size of the mesh cylinder surface in the quenching conveyor cylinder is fixed, if the aperture is small, heat cannot be quickly transferred to the surface of the automobile fastener for heat treatment. When the aperture is large, some smaller automobile fasteners will pass through the mesh cylinder surface and fall into the quenching chamber 9, which will cause inconvenience to the heat treatment of the automobile fasteners. In addition, the falling automobile fasteners will hit the heating tube 10, causing damage to the heating tube 10.

[0030] In this embodiment, a bore tube 803 of a suitable aperture is selected according to the size of the automotive fastener to be heat treated. At this time, the fixing bolt 808 is rotated by a tool until it is completely disengaged from the inside of the bolt hole 807. Then, the sealing ring 802 is pulled hard by the handle 805 to slide the bore tube 803 off the surface of the quenching cylinder 7. Then, a new bore tube 803 is sleeved on the surface of the quenching cylinder 7, and the clamping block 806 is aligned with the inside of the clamping seat 804 and clamped in. Then, the fixing bolt 808 is tightened into the inside of the bolt hole 807 to achieve the installation and fixation of the bore tube 803.

[0036] In this embodiment, it is convenient to be installed on the surface of the quenching cylinder 7. Example 2

[0037] On the basis of Example 1, the preferred embodiment of the heat treatment device for automobile fasteners provided by the present invention is as follows: Figures 1 to 5As shown: the anti-blocking component 2 includes: a fixed plate 201 fixedly connected to the upper end of one side of the quenching chamber 9; a slide groove 202 opened on one side of the bottom end of the fixed plate 201; a return spring 207 fixedly connected to the inner wall of the slide groove 202; a slider 203 fixedly connected to one end of the return spring 207; a sliding plate 205 fixedly connected to the bottom end of the slider 203, one side of the sliding plate 205 is fixedly connected to rubber blocks 204 at equal intervals, and the middle position of the other side of the sliding plate 205 is fixedly connected to a fixed block 206; a micro drive motor 209 fixedly connected to the other side of the bottom end of the fixed plate 201, and the output end of the micro drive motor 209 is fixedly connected to a cam 208 through a coupling.

[0038] In this embodiment, when adding automobile fasteners to the inside of the quenching cylinder 7 through the feed hopper 1, the micro drive motor 209 is started to drive the cam 208 to rotate, and periodically rotates and contacts with the fixed block 206, so that the sliding plate 205 slides and drives the slider 203 to slide inside the slide groove 202 to stretch the reset spring 207 until it drives the rubber block 204 to hit the lower end of the surface of the feed hopper 1. After the cam 208 rotates away from the fixed block 206, the elastic force of the reset spring 207 is used to make the slider 203 slide and drive the sliding plate 205 to slide back to its original position, and then the sliding plate 205 slides back and forth to make the rubber block 204 vibrate and feed the lower end of the surface of the feed hopper 1.

[0039] In a further preferred embodiment of the present invention, a sliding structure is formed between the slider 203 and the interior of the slide groove 202 , and the slide groove 202 and the slider 203 are T-shaped.

[0040] In this embodiment, the sliding of the T-shaped slider 203 and the interior of the sliding groove 202 is utilized to improve the smoothness of the sliding back and forth sliding of the sliding plate 205 .

[0041] In a further preferred embodiment of the present invention, one side of the rubber block 204 is arc-shaped, and the rubber block 204 is fixedly connected to one side of the sliding plate 205 by bolts.

[0042] In this embodiment, the arc-shaped rubber block 204 is used to facilitate contact and collision with the surface of the feed hopper 1 .

[0043] In a further preferred embodiment of the present invention, the fixing block 206 is arc-shaped, and the fixing block 206 and the cam 208 are located in the same horizontal plane.

[0044] In this embodiment, the fixing block 206 and the cam 208 are located in the same horizontal plane, so that the rotational contact between the two is smoother.

[0045] The working principle of the utility model is as follows: first, a bore tube 803 of a suitable aperture is selected according to the size of the automobile fastener to be heat treated. At this time, the fixing bolt 808 is rotated by a tool until it is completely disengaged from the inside of the bolt hole 807. Then, the sealing ring 802 is pulled hard by the handle 805 to slide the bore tube 803 off the surface of the quenching tube 7. Then, a new bore tube 803 is sleeved on the surface of the quenching tube 7, and the clamping block 806 is aligned with the inside of the clamping seat 804 and clamped in. Then, the fixing bolt 808 is screwed into the bolt hole 807 to achieve the installation and fixation of the bore tube 803. After the bore tube 803 is installed, the sealing sleeve 801 is used to seal the distance between the surface of the bore tube 803 and the opening on one side of the quenching chamber 9 to prevent heat leakage. At the same time, the sealing ring 802 with a larger area can block and seal one side of the quenching chamber 9 again, further improving the sealing effect.

[0046] Then, the heating tube 10 is started to transfer heat through the hole tube 803 and the through hole 11 to the inside of the quenching cylinder 7 for preheating, and then the automobile fasteners are added to the inside of the quenching cylinder 7 through the feed hopper 1. When the automobile fasteners are added to the inside of the quenching cylinder 7 through the feed hopper 1, the micro drive motor 209 is started to drive the cam 208 to rotate, and periodically rotates and contacts with the fixed block 206, so that the sliding plate 205 slides and drives the slider 203 to slide in the slide groove 202 to stretch the return spring 207 until the rubber block 204 hits the lower end of the feed hopper 1 surface. After the cam 208 rotates away from the fixed block 206, the elastic force of the return spring 207 is used to make the slider 203 slide and drive the sliding plate 205 to slide back to its original position, and then the back and forth sliding of the sliding plate 205 causes the rubber block 204 to vibrate and feed the lower end of the feed hopper 1 surface, which can effectively avoid the automobile fasteners from being blocked at the lower end of the feed hopper 1 and causing poor feeding.

[0047] Then the automobile fasteners enter the quenching cylinder 7. At this time, the servo motor 3 is started to drive the spiral feeding rod 6 to rotate, thereby causing the automobile fasteners inside the quenching cylinder 7 to rotate and slowly move away from the servo motor 3. This can achieve uniform heating of the automobile fasteners, making it easier to perform heat treatment on them. After the heat treatment is completed, they can be discharged through the discharge port on one side of the quenching cylinder 7.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
