Description

Technical Field

[0001] This utility model relates to a tempering furnace for spring production, belonging to the field of spring processing technology. Background Technology

[0002] A spring is a device that uses the principle of elasticity to store and release mechanical energy. It is typically made of a metal coil. When an external force is applied to a spring, it deforms, and the released energy allows the spring to return to its original shape. Springs are widely used in various mechanical and electronic devices, such as automotive suspension systems, clocks, and toys. During the manufacturing process, springs undergo tempering in a tempering furnace to eliminate internal stresses, thereby increasing the spring's stability and toughness.

[0003] To facilitate the tempering of springs, some portable tempering furnaces have been developed on the market. These furnaces can be moved directly to the discharge end of the spring-making machine, allowing springs produced by the machine to fall directly into the furnace for tempering. However, the height of the receiving hopper in these portable furnaces is fixed, while spring-making machines vary in height. Therefore, portable furnaces are not suitable for receiving springs from machines of different heights, thus limiting their functionality. This invention proposes a tempering furnace for spring production to address these issues. Utility Model Content

In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0024] like Figures 1-4 As shown, a tempering furnace for spring production includes a furnace body 1. The top of the furnace body 1 is provided with a feeding hole 4. Both sides of the top of the furnace body 1 are fixedly connected to a base plate 6 by first bolts 5. The base plate 6 is provided with an elastic telescopic component 2 that can be raised and lowered. The top of the elastic telescopic component 2 is fixedly connected to a receiving hopper 8 by second bolts 7. The bottom of the receiving hopper 8 is provided with a discharge pipe 9. The discharge pipe 9 is coaxially arranged with the feeding hole 4 and can pass into the feeding hole 4. The base plate 6 is provided with an elastic limiting component 3 that locks the telescopic component 2 to adjust its telescopic height.

[0025] In the above technical solution, by setting the elastic telescopic component 2 and the elastic limiting component 3, the height of the elastic telescopic component 2 on the base plate 6 can be adjusted and its height can be fixed and maintained by the limitation of the elastic limiting component 3, thereby adjusting the height of the receiving hopper 8, so that the present invention can receive and temper springs produced by the spring machine discharge end of different heights.

[0026] In this utility model, the elastic telescopic component 2 includes a limiting rod 201. A limiting hole 202 is provided in the outer part of the furnace body 1 on the bottom plate 6. The limiting rod 201 passes through the limiting hole 202. A circular anti-detachment plate 203 is provided at the bottom of the limiting rod 201. A connecting plate 204 is threadedly connected to the top of the limiting rod 201. The connecting plate 204 is fixedly connected to the receiving hopper 8 by a second bolt 7. A support spring 205 is sleeved on the limiting rod 201. One end of the support spring 205 abuts against the bottom of the connecting plate 204, and the other end of the support spring 205 abuts against the top of the bottom plate 6.

[0027] In the above technical solution, the connecting plate 204 can be used to connect the limiting rod 201 and the receiving hopper 8. The sliding limiting rod 201 can drive the feeding hopper to rise and fall at its high and low positions in the limiting hole 202. The supporting spring 205 sleeved on the limiting rod 201 can support the height of the feeding hopper. The anti-detachment plate 203 can prevent the limiting rod 201 from falling out of the limiting hole 202.

[0028] In this utility model, the elastic limiting component 3 includes a mounting groove 301, which is formed on the end face of the base plate 6 away from the feed hole 4. A telescopic hole 302 is formed in the center of the side wall of the mounting groove 301 near the feed hole 4. A circular telescopic plate 303 is installed in the mounting groove 301. A spherical block 304 is provided at the end of the telescopic plate 303 near the telescopic hole 302. The diameter of the spherical block 304 is smaller than the diameter of the telescopic hole 302.

The spherical block 304 can be stuck in the groove 10 under the action of the telescopic spring 306 after passing through the telescopic hole 302.

[0029] In the above technical solution, by setting a telescopic spring 306 between the telescopic plate 303 and the threaded plug 305 in the mounting groove 301, when the limiting rod 201 moves up and down in the limiting hole 202, when the groove 10 on the limiting rod 201 moves to the position of the spherical block 304, under the action of the telescopic spring 306, the spherical block 304 is stuck in the groove 10. Without the application of external force, the limiting rod 201 can be restricted and fixed by the locking between the spherical block 304 and the groove 10, thereby fixing the height adjustment position of the receiving hopper 8.

[0030] In this utility model, in order to facilitate the spring for the end of tempering to fall out of the furnace body 1, a discharge hopper 11 is provided on the right side of the furnace body 1 near the bottom, and the end of the discharge hopper 11 is inclined downward.
