Description

Technical Field

[0001] This utility model relates to the field of steel shot production technology, and in particular to an air-cooled quenching device for steel shot production. Background Technology

[0002] Steel shot is a type of spherical particle made from special materials through a special heat treatment process. It is widely used for descaling and rust removal on steel workpieces before painting. Centrifugal shot blasting equipment is frequently used in this process, as the spherical shape and relatively low hardness minimize wear on the equipment. After numerous processing steps, the ferrous raw material is prepared into shaped steel shot. Once formed, the steel shot requires a certain degree of heat treatment and testing before it can meet the required performance conditions. Heat treatment includes various forms such as normalizing, tempering, annealing, and quenching, which can satisfy all the performance requirements of the steel shot.

[0003] A search revealed that CN211367644U discloses an air-cooled quenching device for steel shot production. The device has a base with a width greater than the body. Five lower high-pressure fans are mounted on the base on the side of the body. Three fan supports are mounted on the upper surface of the body, each supporting a higher high-pressure fan. An opening is located on the left side of the body, connected to a feed inlet, which is fixed to the body via a bracket. An opening is also located on the right side of the body, connected to a discharge outlet. An upper partition plate is located on the upper part of the body's inner side, and a lower partition plate is located on the lower part. Two partition plates are positioned between the upper partition plate and the top side wall of the body.

[0004] The air-cooled quenching device for steel shot production described in the prior art achieves air-cooled quenching of steel shot without the need for retrieval and drying, but it cannot ensure that the steel shot to be air-cooled enters the machine body continuously and evenly, thus reducing the practicality of the device.

[0005] Therefore, we propose an air-cooled quenching device for steel shot production. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide an air-cooled quenching device for steel shot production.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an air-cooled quenching device for steel shot production, comprising a machine body, a discharge pipe fixedly inserted on the right side of the machine body, a feed box fixedly inserted on the left side of the machine body, a guide plate fixedly installed on the left inner wall of the feed box, the front and rear ends of the guide plate respectively fitting against the front and rear inner walls of the feed box, a storage box provided on the upper side of the feed box, a feed pipe fixedly inserted at the bottom of the storage box, the bottom end of the feed pipe fixedly inserted at the top of the feed box, a feed shaft provided inside the feed pipe, a spiral guide vane fixedly fitted on the feed shaft, the outer wall of the spiral guide vane fitting against the inner wall of the feed pipe, a cover plate fixedly installed on the top of the storage box, a connecting shaft rotatably inserted on the cover plate, a stirring shaft fixedly connected to the bottom end of the connecting shaft, stirring rods fixedly fitted at the upper and lower ends of the stirring shaft respectively, and the top end of the feed shaft fixedly installed at the bottom of the stirring shaft.

[0008] Furthermore, mounting brackets are fixedly installed at the left and right ends of the bottom of the machine body, and a base plate is provided on the lower side of each mounting bracket. A damper is fixedly installed on the top of each base plate, and the telescopic ends of the top of the two dampers are fixedly installed on the bottom of the two mounting brackets respectively.

[0009] Furthermore, each damper is provided with a telescopic spring on both the front and rear sides, and each telescopic spring is fixedly installed with a mounting sleeve at both the upper and lower ends. The sides of each pair of mounting sleeves that are far apart from each other are respectively fixedly installed on the sides of the mounting frame and the base plate that are close to each other.

[0010] Furthermore, a driven gear is fixedly installed at the top of the connecting shaft, and the driven gear is meshed with a driving gear.

[0011] Furthermore, a drive motor is fixedly installed at the top right end of the cover plate, and the drive gear is installed at the top output end of the drive motor via a transmission shaft.

[0012] Furthermore, a hopper is fixedly inserted into the top left end of the cover plate.

[0013] This utility model provides an air-cooled quenching device for steel shot production. It has the following beneficial effects:

[0014] 1. This air-cooled quenching device for steel shot production involves feeding steel shot into a storage bin via a hopper. The drive motor is then activated to rotate the drive gear, which in turn rotates the connecting shaft via a driven gear. The connecting shaft, through a stirring shaft, rotates the feed shaft inside the feed pipe. The feed shaft, via spiral guide vanes, causes the steel shot in the storage bin to fall evenly and stably onto a guide plate within the feed bin. The shot then enters the machine body through the guide plate, undergoes air-cooled quenching, and is finally discharged through a discharge pipe. This process ensures a uniform and stable flow of steel shot into the machine body, preventing accumulation and blockage, and effectively improving the device's practicality.

[0015] 2. This air-cooled quenching device for steel shot production, after starting the drive motor, drives the connecting shaft to rotate through the drive gear and driven gear. The connecting shaft drives the stirring shaft to rotate, and the stirring shaft drives the stirring rod to stir the steel shot in the storage box, ensuring that the steel shot smoothly falls onto the guide plate through the spiral guide plate, further improving the practicality of the device.

[0016] 3. This air-cooled quenching device for steel shot production, when the machine body is used for air-cooled quenching of steel shot, the operation of the fan causes the machine body to vibrate. The machine body is equipped with a compression and extension spring, and a damper is set between the mounting frame and the base plate to achieve the effect of vibration reduction and noise reduction, which effectively improves the applicability of the device.

[0027] An air-cooled quenching apparatus for steel shot production, such as Figure 1-4As shown, the machine includes a body 1. A discharge pipe 5 is fixedly inserted on the right side of the body 1, and a feed box 2 is fixedly inserted on the left side of the body 1. A guide plate 13 is fixedly installed on the inner left wall of the feed box 2. The front and rear ends of the guide plate 13 are respectively attached to the front and rear inner walls of the feed box 2. A storage box 4 is provided on the upper side of the feed box 2. A feed pipe 3 is fixedly inserted at the bottom of the storage box 4. The bottom end of the feed pipe 3 is fixedly inserted at the top of the feed box 2. A feed shaft 7 is provided inside the feed pipe 3. A spiral guide vane 12 is fixedly fitted on the feed shaft 7. The outer wall of the spiral guide vane 12 is attached to the inner wall of the feed pipe 3. A cover plate 9 is fixedly installed on the top of the storage box 4. A connecting shaft 19 is rotatably inserted on the cover plate 9. A stirring shaft 10 is fixedly connected to the bottom end of the connecting shaft 19. Stirring rods 11 are fixedly fitted at the upper and lower ends of the stirring shaft 10. The top end of the feed shaft 7 is fixedly installed at the bottom of the stirring shaft 10. Mounting brackets 14 are fixedly installed at the bottom left and right ends of the body 1. Each mounting bracket 14 has a base plate 18 on its lower side. Each base plate 18 has a damper 17 fixedly installed on its top. The telescopic ends of the top of the two dampers 17 are fixedly installed at the bottom of the two mounting brackets 14 respectively. Each damper 17 has a telescopic spring 6 on its front and rear sides. Each telescopic spring 6 has a mounting sleeve 16 fixedly installed at its upper and lower ends.

A discharge hopper 8 is fixedly inserted at the top left end of the cover plate 9.

[0028] The working principle of this utility model is as follows: When using this device, steel shot is fed into the storage box 4 through the discharge hopper 8. Then, the drive motor 15 is started to drive the drive gear 21 to rotate. The drive gear 21 drives the connecting shaft 19 to rotate through the driven gear 20. The connecting shaft 19 drives the feeding shaft 7 set in the feeding pipe 3 to rotate through the stirring shaft 10. The feeding shaft 7 drives the steel shot in the storage box 4 to fall evenly and stably onto the guide plate 13 set in the feeding box 2 through the spiral guide plate 12. Then, it enters the machine body 1 through the guide plate 13. After being air-cooled and quenched by the machine body 1, it is finally discharged through the discharge pipe 5. This achieves the effect of ensuring that the steel shot enters the machine body 1 evenly and stably, avoiding accumulation and blockage, and effectively improving the practicality of the device.

[0029] After the drive motor 15 is started, the connecting shaft 19 is driven to rotate through the drive gear 21 and the driven gear 20. The connecting shaft 19 drives the stirring shaft 10 to rotate. The stirring shaft 10 drives the stirring rod 11 to stir the steel sand in the storage box 4, ensuring that the steel sand passes smoothly through the spiral guide plate 12 and falls onto the guide plate 13, further improving the practicality of the device.

[0030] When steel sand is air-cooled and quenched by the machine body 1, the operation of the fan causes the machine body 1 to vibrate. The machine body 1 compresses the telescopic spring 6 through the mounting sleeve 16, and the damper 17 set between the mounting frame 14 and the base plate 18 achieves the effect of vibration reduction and noise reduction, which effectively improves the applicability of the device.
