Description

Technical Field

[0001] This utility model relates to the field of beryllium copper strip processing technology, specifically to a beryllium copper strip heat treatment and quenching device. Background Technology

[0002] Beryllium copper strip is an alloy strip with copper as the base and a small amount of beryllium added. It has the characteristics of high strength, high elasticity, excellent electrical and thermal conductivity, and is widely used in the fields of electronics, electrical appliances, and precision instruments. In the processing of beryllium copper strip, it is processed by quenching to give it high hardness, high strength and wear resistance.

[0003] During the quenching process of beryllium copper strip, the heated beryllium copper strip is usually placed directly in the quenching tank, which causes the quenching medium in the quenching tank to heat up quickly and the quenching effect to be poor. At the same time, when the beryllium copper strip is in the quenching tank, it is impossible to effectively limit the beryllium copper strip, and the transport of the beryllium copper strip in the quenching tank is unstable. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment and quenching device for beryllium copper strips to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a beryllium copper strip heat treatment quenching device, including a quenching pool, the quenching pool being divided into three quenching grooves, fixed frames symmetrically fixedly installed on the middle of both sides of the quenching pool, limit rods symmetrically fixedly installed between corresponding two fixed frames, positioning frames symmetrically slidingly installed between the two limit rods, an upper conveying roller rotatably installed between the tops of corresponding two fixed frames via bearings, an mounting plate fixedly installed at the top of the quenching pool corresponding to the upper middle position of the quenching grooves, and a lower conveying roller movably installed below the mounting plate.

[0006] As a further preferred embodiment of this technical solution, a bidirectional screw is rotatably mounted between the two corresponding fixing frames via bearings. The two ends of the bidirectional screw are respectively threaded to the middle of the two positioning frames. A first motor is fixedly mounted on one side of one of the fixing frames, and the output shaft of the first motor is fixedly connected to one end of the bidirectional screw via a shaft connector.

[0007] As a further preferred embodiment of this technical solution, the mounting plate has symmetrical sliding holes in the middle, and a sliding rod is slidably installed inside the sliding hole. A mounting base is fixedly installed between the bottom ends of the two sliding rods. The lower conveying roller is rotatably installed in the middle of the mounting base through a bearing. A spring is sleeved on the outside of the sliding rod. One end of the spring is fixedly connected to the outer wall of the sliding rod, and the other end of the spring is fixedly connected to the lower surface of the mounting plate.

[0008] As a further preferred embodiment of this technical solution, both ends of the mounting plate are rotatably mounted with stirring shafts via bearings, and the bottom end of the stirring shaft is fixedly mounted with stirring blades via bolts.

[0009] As a further preferred embodiment of this technical solution, a second motor is fixedly mounted on one end of the mounting plate at the position corresponding to one of the stirring shafts by bolts. The output shaft of the second motor is fixedly connected to the top end of the stirring shaft through a shaft connector.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, the beryllium copper strip heat treatment quenching device includes a quenching pool 1, which is divided into three quenching tanks 2. Each quenching tank 2 is equipped with an inlet pipe and an outlet pipe to facilitate the exchange of quenching media. The exchange rates of the quenching media in the three quenching tanks 2 are different, with the beryllium copper strip passing through the quenching tank 2 first experiencing the fastest exchange rate. Fixed frames 3 are symmetrically fixedly installed on the middle of both sides of the quenching pool 1. Limiting rods 4 are symmetrically fixedly installed between corresponding two fixed frames 3. Positioning frames 5 are symmetrically slidably installed between the two limiting rods 4. An upper conveying roller 6 is rotatably installed between the tops of corresponding two fixed frames 3 via bearings. An installation plate is fixedly installed on the top of the quenching pool 1 at a position above the middle of the quenching tank 2. 7. A lower conveying roller 8 is movably installed below the mounting plate 7. The heat-treated beryllium copper strip is passed sequentially through three staggered upper conveying rollers 6 and lower conveying rollers 8. The heat-treated beryllium copper strip is cooled sequentially through three quenching tanks 2. The quenching medium in the first quenching tank 2 of the beryllium copper strip heats up the fastest. However, the high-temperature quenching medium in this quenching tank 2 will not dissipate into the other quenching tanks 2. The beryllium copper strip is cooled sequentially by the high-temperature quenching medium in the three quenching tanks 2, which improves the cooling effect of the beryllium copper strip. The beryllium copper strip is positioned by two positioning frames 5 to prevent the beryllium copper strip from deflecting. When quenching and cooling beryllium copper strips of different widths, the distance between the two positioning frames 5 is adjusted to achieve quenching and cooling of beryllium copper strips of different widths.

[0022] like Figures 1 to 4 As shown, a bidirectional screw 9 is rotatably mounted between two corresponding fixed frames 3 via bearings. The two ends of the bidirectional screw 9 are threadedly connected to the middle of the two positioning frames 5 respectively. A first motor 10 is fixedly mounted on one side of one of the fixed frames 3. The output shaft of the first motor 10 is fixedly connected to one end of the bidirectional screw 9 via a shaft connector.

[0023] By energizing and controlling the operation of the first motor 10, the first motor 10 will drive the bidirectional screw 9 to rotate. The two ends of the bidirectional screw 9 are respectively threadedly connected to the two positioning frames 5, which will drive the two positioning frames 5 to slide closer or further away along the two limit rods 4, thereby realizing the quenching and cooling of beryllium copper strips of different specifications and widths.

[0024] like Figures 1 to 4 As shown, the mounting plate 7 has symmetrical sliding holes 11 in the middle. A sliding rod 12 is slidably installed inside the sliding hole 11. A mounting base 13 is fixedly installed between the bottom ends of the two sliding rods 12. The lower conveying roller 8 is rotatably installed in the middle of the mounting base 13 through a bearing. A spring 14 is sleeved on the outside of the sliding rod 12. One end of the spring 14 is fixedly connected to the outer wall of the sliding rod 12, and the other end of the spring 14 is fixedly connected to the lower surface of the mounting plate 7.

[0025] The spring 14 pushes the slide bar 12, which drives the lower conveyor roller 8 to continuously press down on the beryllium copper belt, ensuring the beryllium copper belt is taut and improving the stability of the beryllium copper belt conveying.

[0026] like Figures 1 to 4 As shown, both ends of the mounting plate 7 are rotatably mounted with stirring shafts 15 via bearings, and the bottom end of the stirring shafts 15 is fixedly mounted with stirring blades 16 by bolts.

[0027] By controlling the rotation of the stirring blade 16 at the bottom of the stirring shaft 15, the high-temperature quenching medium in the quenching tank 2 can be stirred, the quenching medium in different positions in the quenching tank 2 can be mixed, and the quenching medium in different positions in the quenching tank 2 can be flowed to the vicinity of the beryllium copper strip to improve the quenching effect.

[0028] like Figures 1 to 4 As shown, a second motor 17 is fixedly installed on one end of the mounting plate 7 at the position corresponding to one of the stirring shafts 15 by bolts. The output shaft of the second motor 17 is fixedly connected to the top end of the stirring shaft 15 through a shaft connector. A pulley 18 is fixedly installed on the top end of the stirring shaft 15. A transmission belt 19 is installed between the two pulleys 18 installed on the mounting plate 7.

[0029] By energizing and controlling the operation of the second motor 17, the second motor 17 will drive one of the stirring shafts 15 to rotate, and the transmission between the two pulleys 18 via the transmission belt 19 will drive both stirring shafts 15 to rotate simultaneously.

[0030] like Figures 1 to 4 As shown, guide rollers 20 are rotatably mounted on both ends of the top of the quenching pool 1 via bearings.

[0031] The guide roller 20 can guide the beryllium copper strip being fed into the quenching tank 1.

[0032] like Figures 1 to 4 As shown, steel plates are welded to the corresponding surfaces of the two positioning frames 5.

[0033] This can prevent excessive wear of the positioning frame 5 when the beryllium copper strip comes into contact with the positioning frame 5.

[0034] This utility model provides a heat treatment and quenching device for beryllium copper strip, the specific working principle of which is as follows:

[0035] When the device is in use, the heat-treated beryllium copper strip is passed sequentially through the guide roller 20 at one end, three staggered upper conveying rollers 6 and lower conveying rollers 8, and then through the guide roller 20 at the other end. The heat-treated beryllium copper strip is cooled sequentially through three quenching tanks 2. The quenching medium in the first quenching tank 2 of the beryllium copper strip heats up the fastest, but the high-temperature quenching medium in this quenching tank 2 will not dissipate into the other quenching tanks 2. The beryllium copper strip is cooled sequentially through the high-temperature quenching medium in the three quenching tanks 2, thereby improving the cooling effect of the beryllium copper strip.

[0036] When quenching and cooling beryllium copper strip, two positioning frames 5 are used to position the conveyed beryllium copper strip to prevent it from deflecting. When quenching and cooling beryllium copper strips of different widths, the first motor 10 is powered on and controlled to rotate. The first motor 10 will drive the bidirectional screw 9 to rotate. The two ends of the bidirectional screw 9 are respectively connected to the two positioning frames 5 by threads, which will drive the two positioning frames 5 to slide closer or further away from the two limit rods 4, so as to realize the quenching and cooling of beryllium copper strips of different widths.

[0037] When quenching and cooling the beryllium copper strip, the second motor 17 is powered on and controlled to run. The second motor 17 will drive one of the stirring shafts 15 to rotate. The transmission belt 19 will drive the two pulleys 18 to rotate simultaneously. The stirring blades 16 at the bottom of the stirring shaft 15 will rotate, which can stir the high-temperature quenching medium in the quenching tank 2. The quenching medium in different positions in the quenching tank 2 can be mixed and flow to the vicinity of the beryllium copper strip, thereby improving the quenching effect.

[0038] When conveying beryllium copper strip, the spring 14 pushes the slide bar 12, which drives the lower conveying roller 8 to continuously press down on the beryllium copper strip, ensuring the beryllium copper strip is taut and improving the stability of the beryllium copper strip conveying.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
