Description

Technical Field

[0001] This invention relates to the field of machining technology for moving and stationary scroll plates, specifically a fully automated production line for pre-processing of moving and stationary scroll plates for forging of scroll compressors. Background Technology

[0002] As a type of high-efficiency and energy-saving fluid machinery, the forging process is a key link in the manufacturing of the scroll compressor's moving and stationary scrolls, which determines its mechanical properties and forming quality. The surface pretreatment before forging (including preheating and forging shaping coating spraying) directly affects the forging shaping effect of the scroll, the degree of mold wear, and the subsequent processing accuracy.

[0003] Patent document CN113385632A discloses a fully automated production line for pre-treatment of dynamic and static scroll plates in scroll compressor forging. However, the pre-treatment device in this patent document still has the following problems in actual use: First, the preheating equipment and the spraying equipment are independently controlled, resulting in unstable preheating temperatures of the scroll plate workpieces. Furthermore, the timing of spraying does not match the workpiece conveying speed, easily leading to insufficient coating adhesion and peeling, thus affecting forging quality. Second, the scroll plate has an irregular curved surface structure, and the spraying equipment often uses fixed nozzles or spraying in a single direction, making it difficult to achieve complete coverage of the workpiece surface, easily resulting in spraying omissions or localized coating accumulation.

[0004] To address this, we designed a fully automated production line for the pre-forging of dynamic and static scroll plates of a scroll compressor. Summary of the Invention

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 The present invention provides a technical solution: a fully automatic production line for pre-forging of dynamic and static scroll plates of a scroll compressor, including a processing table 1, a coating heating mechanism 2, a spraying mechanism 3 and a transmission mechanism 4.

[0021] A pretreatment box 5 is fixedly installed on the upper surface of the processing table 1. The coating heating mechanism 2 and the spraying mechanism 3 are both installed inside the pretreatment box 5. A chain plate conveyor assembly 6 is installed on the surface of the processing table 1. The chain plate conveyor assembly 6 is used to transport the scroll workpiece to the interior of the pretreatment box 5. The coating heating mechanism 2 is used to preheat the scroll workpiece. The spraying mechanism 3 is used to spray the forging and shaping coating on the surface of the scroll workpiece.

[0022] The spraying mechanism 3 includes a spraying bracket 301. Two extension rods 302 are fixedly connected to the lower surface of the spraying bracket 301. A strip spraying tube 303 is fixedly connected to the bottom end of the two extension rods 302. Several fan-shaped nozzles 304 are fixedly installed on the lower surface of the strip spraying tube 303. The front and rear surfaces of the pretreatment box 5 are provided with corresponding strip-shaped limiting holes 305. The size of the strip-shaped limiting holes 305 matches that of the spraying bracket 301. Both ends of the spraying bracket 301 extend into the interior of the strip-shaped limiting holes 305. Guide sliders 306 are fixedly connected to both ends of the spraying bracket 301. Vertical plates 307 are fixedly connected to both the front and rear surfaces of the pretreatment box 5. Two limiting sliders 308 are fixedly connected to the side of the vertical plate 307.

[0023] The spraying mechanism 3 also includes a paint mixing tank 312 fixedly mounted on the upper surface of the pretreatment box 5. A stirring rod 316 is rotatably mounted on the inner bottom wall of the paint mixing tank 312. Several stirring blades 319 are fixedly mounted on the bottom of the stirring rod 316. A stirring motor 315 is fixedly mounted on the upper surface of the paint mixing tank 312. The rotating shaft of the stirring motor 315 extends into the interior of the paint mixing tank 312 and is fixedly connected to the top of the stirring rod 316. A paint delivery pump 318 is fixedly mounted on the upper surface of the paint mixing tank 312. The input end of 8 is fixedly connected to an inlet pipe 314, the bottom end of which extends into the interior of the paint mixing tank 312. The output end of the paint delivery pump 318 is fixedly connected to a delivery hose 313, the end of which extends away from the paint delivery pump 318 into the interior of the pretreatment box 5. The output end of the delivery hose 313 is fixedly connected to the input end of the strip spray pipe 303. Several fan-shaped nozzles 304 are evenly distributed in a straight line array on the lower surface of the strip spray pipe 303, and the spraying range of the fan-shaped nozzles 304 is forty-five degrees.

[0024] A feeding pipe 311 is fixedly embedded on the upper surface of the paint mixing tank 312. A valve is provided on the surface of the feeding pipe 311. Several stirring blades 319 are evenly distributed in a ring array on the surface of the stirring rod 316.

[0025] It is worth noting that the material is mixed evenly and the spraying effect is stable. The stirring rod 316 and the annular array stirring plate 319 built into the paint mixing tank 312 continuously stir to ensure that the paint concentration is uniform and there is no sedimentation or stratification. The reasonable layout of the fan-shaped nozzle 304 and the reciprocating motion of the spraying bracket 301 work together to control the coating thickness deviation and improve the plastic deformation effect of the vortex workpiece after forging.

[0026] The guide slider 306 has two limiting through holes that match the limiting slide rod 308. The guide slider 306 is slidably connected to the surface of the limiting slide rod 308 through the limiting through holes. A linkage push rod 309 is fixedly connected to the side of the guide slider 306. A movable connecting rod 310 is rotatably connected to the end of the linkage push rod 309 away from the guide slider 306. A return spring 317 is sleeved on the surface of the limiting slide rod 308. One end of the return spring 317 is fixedly connected to the surface of the vertical plate 307, and the other end of the return spring 317 is fixedly connected to the surface of the guide slider 306.

[0027] The transmission mechanism 4 includes a protective shell 401 fixedly installed on the front and rear surfaces of the pretreatment box 5. A drive motor 402 is fixedly connected to the inner wall of the protective shell 401. A drive gear 403 is fixedly connected to the rotating shaft of the drive motor 402. A transmission shaft 404 is rotatably connected to the surface of the pretreatment box 5. A first transmission gear 405 is fixedly connected to the surface of the transmission shaft 404. The position of the first transmission gear 405 corresponds to that of the drive gear 403, and the drive gear 403 meshes with the first transmission gear 405. A linkage shaft 406 is rotatably connected between the front and rear inner walls of the pretreatment box 5. A second transmission gear 407 is fixedly connected to the surface of the linkage shaft 406. The second transmission gear 407 meshes with the first transmission gear 405. The diameter of the first transmission gear 405 is five times that of the second transmission gear 407 and the drive gear 403.

[0028] It is worth noting that the single drive motor 402 is used, which has strong synchronization and excellent coating quality. The synchronous operation of the spraying mechanism 3 and the chain plate conveyor assembly 6 is achieved through gear transmission and synchronous belt transmission, avoiding the operation deviation problem of traditional dual power source equipment. The coating coverage is high, with no spraying omissions or accumulation. The combination of stable preheating temperature of 300℃±5℃ and uniform spraying process significantly improves the coating adhesion and effectively reduces coating peeling and mold wear during the forging process.

[0029] Both ends of the linkage shaft 406 extend into the interior of the protective shell 401, and both ends of the linkage shaft 406 are fixedly connected to the linkage turntable 408. The surface of the linkage turntable 408 is provided with mounting holes, and the inner wall of the mounting holes is rotatably connected to the connecting rod 409 through bearings. The end of the movable connecting rod 310 away from the linkage push rod 309 is rotatably connected to the surface of the connecting rod 409.

[0030] The chain conveyor assembly 6 includes a chain conveyor belt 601 and two drive rollers 602. The chain conveyor belt 601 is installed between the two drive rollers 602 and is located inside the pretreatment box 5. One end of the drive roller 602 is fixedly connected to a driven synchronous pulley 410, and the end of the transmission shaft 404 is fixedly connected to a drive synchronous pulley 411. The position of the drive synchronous pulley 411 corresponds to that of the driven synchronous pulley 410, and the drive synchronous pulley 411 and the driven synchronous pulley 410 are connected by a transmission belt 412.

[0031] It is worth noting that the equipment is widely adaptable and has a long service life: the chain plate conveyor assembly 6 has a strong load-bearing capacity and can adapt to the conveying needs of different specifications of vortex workpieces; the use of protective shell 401 and high-temperature resistant materials effectively protects equipment components and extends the service life of the equipment; the high degree of automation reduces manual intervention. From preheating temperature control, workpiece conveying, paint mixing to coating spraying, the entire process is automated, avoiding processing errors caused by manual intervention, improving the standardization of mass production, and increasing production efficiency compared to traditional equipment.

[0032] The coating heating mechanism 2 includes several electric heating tubes 201, which are fixedly installed between the front and rear inner walls of the pretreatment box 5 and are evenly arranged above the chain conveyor belt 601. The coating heating mechanism 2 is close to the feed port of the pretreatment box 5.

[0033] It is worth noting that the centralized heating layout and single power source design result in low energy consumption, high space utilization, and compact integrated installation of each mechanism. Compared with traditional decentralized equipment, it reduces the overall size, adapts to the space requirements of intensive factory production, and reduces the equipment's floor space cost.

[0034] Working principle: First, the processing parameters are set through the control system, including the heating temperature of the electric heating tube 201 (300℃±5℃) and the rotation speed of the drive motor 402 (adapted to the conveyor belt 601 with a conveying speed of 0.8m / min). The electric heating tube 201 is energized and heated, and the temperature inside the pretreatment box 5 gradually increases. At the same time, the stirring motor 315 starts, driving the stirring rod 316 and stirring blade 319 to rotate inside the paint mixing tank 312, uniformly stirring the forging and shaping paint that has been added beforehand through the feeding pipe 311.

[0035] Once the internal temperature of the pretreatment box 5 reaches the set preheating temperature, the scroll plate workpiece is evenly placed at the feed end of the chain conveyor belt 601. The drive motor 402 starts, and its rotating shaft drives the drive gear 403 to rotate. Since the drive gear 403 meshes with the first transmission gear 405, and the diameter of the first transmission gear 405 is five times that of the drive gear 403, the high-speed rotation of the drive gear 403 is reduced by the first transmission gear 405, driving the transmission shaft 404 to rotate at a uniform speed. The drive synchronous pulley 411 at the end of the transmission shaft 404 drives the driven synchronous pulley 410 to rotate through the transmission belt 412, which in turn drives the drive roller shaft 602 to rotate, causing the chain conveyor belt 601 to run at a set speed (0.8m / min) at a uniform speed, conveying the scroll plate workpiece into the pretreatment box 5. The scroll plate workpiece enters the heating area of ​​the coating heating mechanism 2 along with the chain conveyor belt 601. Several evenly arranged electric heating tubes 201 continuously release heat to preheat the scroll plate workpiece uniformly in all directions. Based on the conveying speed of the chain conveyor belt 601 and the length of the heating zone, the vortex workpiece is kept warm in the preheating zone for 10 minutes to ensure that the workpiece temperature is stable at 300℃±5℃, providing good temperature conditions for subsequent coating spraying and improving coating adhesion.

[0036] While the drive motor 402 drives the transmission shaft 404 to rotate, the first transmission gear 405 meshes with the second transmission gear 407, driving the linkage shaft 406 to rotate. Since the diameter of the first transmission gear 405 is five times that of the second transmission gear 407, the rotational speed of the linkage shaft 406 and the rotational speed of the transmission shaft 404 form a fixed proportional relationship, ensuring that the movement rhythm of the spraying mechanism 3 is synchronized with the conveying speed of the chain conveyor belt 601. The linkage turntables 408 at both ends of the linkage shaft 406 move in a circular motion with the linkage shaft 406, driving the movable connecting rod 310 to move through the connecting rod 409. The movable connecting rod 310 converts the circular motion into linear reciprocating motion, pushing the linkage push rod 309 and the guide slider 306 to move horizontally reciprocating along the limiting slide rod 308. The guide slider 306 drives the spraying bracket 301 to slide back and forth along the extension direction of the strip-shaped limiting hole 305, thereby driving the extension rod 302, the strip-shaped spraying tube 303 and the fan-shaped nozzle 304 to move synchronously back and forth. Simultaneously, the paint delivery pump 318 starts, drawing the uniformly stirred paint from the paint mixing tank 312 through the inlet pipe 314, and conveying it through the delivery hose 313 to the inside of the strip spray pipe 303. The paint is then atomized by several fan-shaped nozzles 304 and sprayed onto the surface of the scroll plate workpiece passing below. The 45-degree spray ranges of the fan-shaped nozzles 304 overlap, and in conjunction with the lateral reciprocating motion of the spray support 301, achieve comprehensive coverage of the scroll plate workpiece surface (including irregular curved surfaces), resulting in a uniform coating thickness. The sprayed scroll plate workpiece continues to run on the chain conveyor belt 601, being transported from the discharge end of the post-processing box 5 to the unloading area. Workers or automated unloading equipment then transfer the sprayed scroll plate workpiece to the next forging process.
