Description

Technical Field

[0001] This invention relates to the field of compressor manufacturing technology, and more specifically to a processing apparatus for compressor crank structure. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas; it is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle.

[0003] The crank inside the compressor converts rotary motion into linear motion. The connecting rod then converts the crank's rotary motion into the piston's reciprocating motion. The shape and size of the crank have a significant impact on the performance of the crank structure. Generally, a cylindrical or elliptical shape is used.

[0004] Currently, when traditional cranks operate for extended periods, the rapid rotation of the crank causes friction between the crank and the air, generating significant heat. If this heat is not dissipated in time, it will be transferred to the crankshaft. As the heat increases, the crank's strength and durability decrease, and it is also prone to slight deformation, which could potentially lead to crankshaft breakage.

[0005] Therefore, there is a current need for a compressor crank that is easy to use for cooling. Summary of the Invention

[0041] The positioning grooves 1-5 in crank 1 serve two purposes: firstly, they reduce the overall weight of crank 1 and save materials; secondly, they facilitate positioning of the entire crank 1 during machining, preventing misalignment of mounting holes 1-4 during punching, which could render crank 1 unusable.

[0042] Combination Figures 1-13As shown, the compressor crank structure processing device provided by the present invention includes a worktable 2.

During feeding, the waste material punched on the placement table 41 can be pushed into the L-shaped discharge hopper tube 12 by the L-shaped cleaning rod 713, thus realizing the recycling of waste material.

[0046] 3. When the molding component 3 needs to be cooled, the lifting groove 54 will drive the L-shaped arm 55 and the nozzle 57 to rotate, so that the nozzle 57 is located between the upper mold 31 and the lower mold 32, which is convenient for cooling the upper mold 31 and the lower mold 32 through the double nozzle 57 later. When cooling is not needed, the nozzle 57 is pulled out from between the upper mold 31 and the lower mold 32 by rotating again, which is convenient for the subsequent processing of the crank 1.

[0047] Example 2

[0048] like Figures 1-13 As shown, based on the above embodiments, this embodiment further provides the following:

[0049] In order to enable the punching assembly 4 to punch and form the crank die, this embodiment will provide the following technical solution:

The second punching rod 49 in the punching assembly 4 realizes the punching forming of the crank 1 mounting holes 1-4.

[0052] Example 3

[0053] like Figures 1-13 As shown, based on the above embodiments, this embodiment further provides the following:

[0054] In order to enable the cooling component 5 to cool the molding component 3, this embodiment will provide the following technical solution:

[0055] The cooling assembly 5 includes a rotating column 51 and a long rod 52.

[0057] Example 4

[0058] like Figures 1-13 As shown, based on the above embodiments, this embodiment further provides the following:

[0059] In order to enable the clamping assembly 7 to move the crank in the forming assembly 3 into the punching assembly 4, and to unload the formed crank in the punching assembly 4, this embodiment provides the following technical solution:

[0060] The clamping assembly 7 includes vertical rods 71. Two vertical rods 71 ​​are fixedly connected to one side of the L-shaped plate 6.

The clamping assembly 7 also includes an L-shaped cleaning rod 713, which is fixedly connected to one side of the opposing clamping rod 710 and between the first clamping jaw 711 and the second clamping jaw 712.

[0061] By using a double-headed cylinder 79 in conjunction with a bidirectional clamping rod 710, a first clamping jaw 711, and a second clamping jaw 712, the crank 1 in the forming assembly 3 and the punching assembly 4 can be clamped respectively. After clamping, the crank in the forming assembly 3 can be moved into the punching assembly 4 by the cooperation of the lifting rod 10 and the pneumatic rod 76. At the same time, the crank in the punching assembly 4 is unloaded.

[0062] During feeding, the waste material from the stamping process on the placement table 41 can be cleaned up by using the L-shaped cleaning rod 713.

[0063] To achieve the above-mentioned technical effects, this embodiment will provide the following technical solution:

[0065] The formed crank 1 is unloaded through the unloading chute 11, and the waste material stamped off the surface of the crank 1 is recycled through the L-shaped discharge pipe 12.

[0066] Working principle and usage process of this invention:

[0067] In use:

[0068] During production, a long aluminum rod is first cut into equal-length aluminum rods using a cutting machine. After cutting, the aluminum rods are placed in a heating furnace for heating. When the specified temperature is reached, the heated aluminum rods are taken out. After being taken out, one end of the heated aluminum rod is hammered using a hammering machine to make the aluminum rod thicker at one end and thinner at the other, with an overall shape resembling a beer bottle.

[0069] At this point, the thinner end of the hammer is inserted into the first cylindrical hole 35 in the inner cavity of the lower mold 32. After insertion, the hydraulic rod 8 is activated. The hydraulic rod 8 will drive the lifting plate 10 and the flat plate 9 to move downwards. As the flat plate 9 moves downwards, it will drive the upper mold 31 to move downwards. As the upper mold 31 moves downwards, it will cooperate with the lower mold 32 to compress the thicker end of the aluminum rod into a crank shape. As the lifting rod 10 moves downwards, it will drive the first rack 33 to move downwards. As the first rack 33 moves downward, it will drive the second rack 37 to move upward under the action of the flip gear 36. As the second rack 37 moves upward, it will drive the extension rod 310 to move upward. As the extension rod 310 moves upward, it will drive the punch 311 and the cross block 313 to move upward. As the punch 311 moves upward, it will start to squeeze the thinner end of the aluminum rod, making the thinner end of the aluminum rod into a cylindrical shape, and stamping a cross oil groove 1-7 at the bottom.

[0070] After stamping, the hydraulic rod 8 is activated to move in the reverse direction. As the upper mold 31 moves upward with the hydraulic rod 8, and as the upper mold 31 and lower mold 32 disengage, the double-headed cylinder 79 is activated. When the double-headed cylinder 79 operates, it drives the opposing clamping rods 710 to move in opposite directions. As the two sets of opposing clamping rods 710 move, they drive the first clamping jaw 711, the second clamping jaw 712, and the L-shaped cleaning rod 713 to move in opposite directions. When the first clamping jaw 711 moves in opposite directions, it can clamp the crank prototype formed in the lower mold 32. When the second clamping jaw 712 clamps in opposite directions, it can clamp the formed crank on the placement table 41. At the same time, the hydraulic rod 8 also drives the flat plate 9 and the lifting rod 10 to move upward.As the lifting rod 10 moves upward, it drives the longitudinal rod 77 and the first rack 33 to move upward. As the longitudinal rod 77 moves upward, it drives the crossbar 74, the first gripper 711, the second gripper 712, and the L-shaped cleaning rod 713 to move upward. As the first gripper 711 and the second gripper 712 move upward, the lower mold 32 and the crank on the placement table 41 can be removed. After removal, the pneumatic rod 76 is activated. When the pneumatic rod 76 operates, it drives the longitudinal rod 77 to slide within the second T-slot 75. As the longitudinal rod 77 moves, it drives the first gripper 711 and the second gripper 712 to move. The movement of the first gripper 711 will move the crank prototype to the upper part of the placement platform 41. As the second gripper 712 moves, it will move the punched crank to the unloading chute 11. After the punched crank leaves the placement platform 41, the L-shaped cleaning rod 713 will arrive at the upper part of the placement platform 41 before the first gripper 711. Due to the lower height of the L-shaped cleaning rod 713, its bottom surface can only contact the top surface of the placement platform 41. As the L-shaped cleaning rod 713 moves forward, it can push the remaining waste material on the placement platform 41 into the L-shaped discharge pipe 12, facilitating the disposal of the waste. During the recovery process, when the crank prototype moves to the upper part of the placement platform 41 along with the first gripper 711, the pneumatic rod 76 is stopped, and the hydraulic rod 8 is activated again, causing it to move downwards. As the hydraulic rod 8 moves downwards, the lifting rod 10 will no longer lift the longitudinal rod 77. Simultaneously, the lifting rod 10 will move downwards under the influence of gravity, placing the crank prototype on the first gripper 711 onto the placement platform 41. With the crank prototype in place, the double-headed cylinder 79 is activated. When the double-headed cylinder 79 operates, the first gripper 711 and the second gripper 712 will disengage. After the first gripper 711 disengages, the crank prototype... The crank is placed on the placement table 41. When the second gripper 712 is released, the formed crank can be placed into the unloading slide 11. After the gripper is released, the pneumatic rod 76 is activated again. The pneumatic rod 76 drives the first gripper 711 and the second gripper 712 to reset. When the hydraulic rod 8 is pressed down again, the forming component 3 can extrude another aluminum rod into a crank prototype. The downward movement of the pressure plate 46 will drive the pressure ring 47 to move downward. When the pressure ring 47 moves downward, the excess waste material on the surface of the crank prototype can be cut off. When the first punching rod 48 and the second punching rod 49 move downward, the crank prototype can be punched to form it.

[0071] As the first rack 33 moves upward, it drives the second rack 37 downward via the flip gear 36. The downward movement of the second rack 37 then drives the long rod 52 downward. This downward movement of the long rod 52 causes the cylindrical rod 53 to slide within the second straight groove 543. As the cylindrical rod 53 slides within the second straight groove 543, it provides time for the double-headed cylinder 79 to operate, facilitating subsequent clamping. When the cylindrical rod 53 enters the spiral groove 542, it drives the rotating column 51 to rotate. As the rotating column 51 rotates, it... The L-shaped arm 55 is rotated, and as the L-shaped arm 55 rotates, the nozzle 57 is driven into the space between the upper mold 31 and the lower mold 32. When the L-shaped arm 55 rotates 90 degrees, the first gripper 711 will also drive the crank prototype to leave from above the lower mold 32. When the nozzle 57 enters the space between the upper mold 31 and the lower mold 32, air and water are blown and sprayed to cool the upper mold 31 and the lower mold 32. When the cylindrical rod 53 enters the second straight groove 543, space is provided, allowing the nozzle 57 to stay for a longer time.
