Description

Technical Field

[0001] The invention relates to a movable and stationary scroll, and more specifically to a movable and stationary scroll of a scroll compressor and a processing technology thereof. Background Art

[0002] The scroll compressor is a positive displacement compressor, and its core components include an orbiting scroll and a stationary scroll, which are usually called orbiting and stationary scrolls. The orbiting scroll is driven by a crankshaft with a very small eccentricity and is constrained by an anti-rotation mechanism to make a planar motion with a very small radius around the stationary scroll, thereby forming a series of crescent-shaped cylindrical working volumes in cooperation with the end plate. During operation, the gas is sucked into the periphery of the stationary scroll through the air filter element. As the eccentric shaft rotates, the gas is gradually compressed in several crescent-shaped compression chambers formed by the meshing of the orbiting and stationary scrolls, and then continuously discharged from the axial hole of the center component of the stationary scroll.

[0003] At present, a movable scroll plate and a stationary scroll plate are respectively provided with a movable scroll tooth and a stationary scroll tooth, and the stationary scroll tooth is longer than the movable scroll tooth, and the difference in the number of tooth rings between the two is large, which leads to a larger outer diameter dimension of the stationary scroll plate, increases the outer dimensions of the movable and stationary scroll plates, increases the processing time of the scroll profile, and makes the processing cost higher. In addition, in the process of forging the movable and stationary scroll plates, more manual means are used and the degree of automation is low. Therefore, the labor burden is heavy, and the processing efficiency is greatly affected by manual labor, which leads to unstable product quality control. Summary of the invention

In the forging process, the blank is conveyed by a fully automatic production line, so that the blank can be heated and forged in turn. The operations are all automatically performed with a high degree of automation, eliminating manual intervention, thereby effectively reducing the manual burden, making the processing efficiency higher, and being able to effectively control product quality, meeting the needs of mass production.

[0022] See also Figure 3-5As shown, the forging die includes a base 5, a lower die 6 is arranged on the base 5, and brackets 7 are arranged on both sides of the lower die 6 on the base 5, an upper die 8 is slidably connected between the brackets 7, and the upper die 8 and the lower die 6 are arranged opposite to each other. When the forging process is performed, the heated blank can be loaded onto the lower die 6 by a manipulator, and then the pressure rod of the press is connected to the upper die 8, and then the pressure rod is driven downward by the press to push the upper die 8 down, so as to apply pressure to the blank to cause plastic deformation to obtain the desired size. The semi-finished parts of different sizes and shapes are easy to operate and have high efficiency. Among them, guide slides 19 are arranged on the opposite side of the bracket 7, and slide grooves 20 are opened on the two side walls of the upper die 8, and the guide slides 19 are slidably connected to the inside of the slide grooves 20. When the upper die 8 slides between the brackets 7, the guide slides 19 will slide in the inside of the slide grooves 20. The guide slides 19 limit the slide grooves 20, so that the sliding direction of the upper die 8 can be limited, thereby making the forging operation of the forging die more stable and ensuring the forging effect.

[0023] See also Figure 3-5As shown, the brackets 7 are connected by a connecting plate 9, and a through hole 10 is provided on the connecting plate 9. The through hole 10 can be used for the pressure rod of the press to pass through. The connection of the bracket 7 by the connecting plate 9 can improve the structural strength of the forging die and improve the stability during forging. A buckle 11 is provided at the bottom of the bracket 7, and protrusions 12 for snapping into the inside of the buckle 11 are provided on the base 5 at both sides of the lower die 6. A first through hole 13 is provided at both ends of the buckle 11, and a first screw hole 14 for communicating with the first through hole 13 is provided on the protrusion 12. When the forging die needs to be assembled, the protrusion 12 can be snapped into the inside of the buckle 11 for pre-positioning, so that the first through hole 13 is aligned with the first screw hole 14 and is connected. By inserting a bolt into the first through hole 13 and screwing it into the first screw hole 14, the bracket 7 can be firmly installed on the base 5, and then the upper die 8 can be placed between the two brackets 7 to achieve assembly. The arrangement makes the assembly of the forging die more convenient. When transporting the forging die, the base 5, the bracket 7 and the upper die 8 can be disassembled for transportation, which makes the transportation operation easier and more convenient. A support block 15 is provided on the opposite side of the bracket 7, and abutment plates 16 for contacting with the support block 15 are provided at both ends of the connecting plate 9. Second through holes 17 are provided at both ends of the connecting plate 9, and second screw holes 18 for communicating with the second through holes 17 are provided on the opposite side of the bracket 7. When it is necessary to install the connecting plate 9 on the bracket 7, the connecting plate 9 can be placed between the brackets 7 so that the abutment plates 16 contact with the support block 15, thereby achieving pre-positioning, so that the second through hole 17 is aligned with the second screw hole 18 and is connected. The bolt can be passed through the second through hole 17 and screwed into the second screw hole 18, thereby achieving a firm connection between the connecting plate 9 and the bracket 7. When disassembly is required, it is only necessary to unscrew the bolt, which makes the disassembly and assembly of the forging die more convenient.
