Description

Technical Field

[0001] The present invention relates to the technical field of evaporator shell processing, and in particular to an evaporator shell processing device. Background Art

[0002] The evaporator is a heat exchanger in the refrigeration system. A considerable amount of refrigerant liquid is filled in the evaporator shell. When working, the refrigerant liquid boils at a lower temperature, turns into steam, and absorbs the heat of the cooled substance or medium. In the field of refrigeration equipment, the evaporator plays a vital role, and the evaporator shell, as its key component, directly affects the performance and reliability of the evaporator. With the continuous development of the refrigeration equipment market, higher requirements are placed on the processing quality and production efficiency of the evaporator shell. Stamping, as an efficient forming process, has been widely used in the manufacture of evaporator shells.

[0003] In the existing shell and tube evaporator, since the tubular shell is usually a cylindrical structure, traditional punching equipment is difficult to accurately locate and align the punching position, which easily leads to deviation in the punching position, making it difficult to assemble the subsequent heat exchange tubes and other components, affecting the overall performance of the evaporator. In addition, defects such as burrs and cracks are easily generated during the punching process. The burrs not only affect the appearance quality of the shell, but may also scratch the operator or damage other components during the subsequent assembly process; cracks will reduce the strength and sealing of the shell, affecting the service life and safety of the evaporator, and bringing certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose an evaporator shell processing device. Summary of the Invention

[0037] The support cylinders 38 at both ends are used to control the support bar 34 to move to one side, the fixed rack 36 to move, and the rotating gear 37 to rotate. Under the action of the rotating gear 37, the fixed racks 36 at both ends of the bottom of the side bracket 31 move toward each other, and then the support bars 34 at both ends move toward each other. The inclined surfaces on both sides of the top of the support bar 34 are used to support the bottom of the tubular shell 6, and under the action of the internal support column 43, the tubular shell 6 is supported and fixed to avoid displacement and shaking of the tubular shell 6 during the punching process, which affects the punching accuracy of the tubular shell 6.

[0038] like Figure 6 - Figure 7 As shown, the clamping assembly 5 includes a second support frame 51, a third support frame 52 and an internal expansion clamp 57. The second support frame 51 is fixedly installed on the left side of the support platform 22, and the third support frame 52 is fixedly installed on the left side of the blanking port on the top of the support platform 22. A sleeve block 54 is fixedly installed on the top of the third support frame 52, and a material return block 53 is fixedly installed on the right side of the third support frame 52. A sliding link 55 is movably sleeved inside the sleeve block 54, and the sliding link 55 is movably sleeved on the top of the second support frame 51. A first electric telescopic rod 56 is fixedly installed between the top of the second support frame 51 and the sleeve block 54. The output end of the first electric telescopic rod 56 is fixedly connected to the left end of the sliding link 55, and a fixed frame 58 is fixedly installed on the right side of the sliding link 55.

[0039] In addition, the internal expansion clamp 57 also includes a clamping cylinder 574, which is fixedly mounted on the right end of the sliding connecting rod 55, and a cylinder rod 575 is provided inside the clamping cylinder 574. An extrusion block 576 is fixedly mounted on the right side of the cylinder rod 575, and the left side of the extrusion block 576 is an inclined surface. The extrusion block 576 is movably sleeved inside the right side of the fixed block 573. A pushing groove 5712 is provided at the bottom of the fixed block 573, and the pushing groove 5712 is movably sleeved on the outer surface of the stripping block 53. Push rods 577 are movably sleeved on the four sides of the interior of the fixed block 573, and a movable groove 579 is provided on the left side of the inner wall of the fixed block 573. A connecting block 5710 is fixedly mounted on the left side of the four pushing rods 577. The connecting block 5710 is slidably mounted inside the movable groove 579, and a return spring 5711 is fixedly mounted between the connecting block 5710 and the inner wall of the movable groove 579.

[0040] Among them, the fixed block 573 is movably sleeved inside one end of the tubular shell 6, and the end of the push rod 577 close to the extrusion block 576 is provided with an inclined surface corresponding to the extrusion block 576, and the end of the push rod 577 away from the extrusion block 576 is fixedly installed with the clamping block 578, and the clamping block 578 is embedded in the outer surface of the fixed block 573.

[0041] By means of the extension and retraction of the first electric telescopic rod 56, the sliding link 55 is controlled to move left and right on the top of the sleeve block 54 and the second support frame 51. When the sliding link 55 moves to the right, the fixed block 573 is inserted into one end of the tubular shell 6. The end of the push rod 577 close to the extrusion block 576 is provided with an inclined surface corresponding to the extrusion block 576. The clamping cylinder 574 contracts, and the extrusion block 576 moves to the inside of the fixed block 573. At this time, the push rod 577 is pushed by the extrusion block 576. Under the action, the pushing rod 577 moves outward, causing the clamping block 578 to be squeezed onto the inner wall of one end of the tubular shell 6, thereby clamping one end of the tubular shell 6. When the clamping assembly 5 stops clamping one end of the tubular shell 6, the clamping cylinder 574 extends, causing the squeezing block 576 to move out of the interior of the fixed block 573, and through the reaction force of the reset spring 5711, the pushing rod 577 and the clamping block 578 are retracted to the interior of the fixed block 573, and the clamping assembly 5 stops clamping the tubular shell 6.

[0042] Among them, the internal expansion clamp 57 includes a rotating sleeve 571, a second transmission gear 572 and a clamping block 578. The second transmission gear 572 is fixedly sleeved on the outer surface of the left end of the rotating sleeve 571. A fixed block 573 is fixedly installed on the right side of the rotating sleeve 571. The rotating sleeve 571 is rotatably installed inside the fixed frame 58. The outer surface of the second transmission gear 572 is engaged with the outer surface of the second drive gear 511. The motor frame 59 is fixedly installed on the top of the right end of the sliding link 55. The steering motor 510 is fixedly installed inside the motor frame 59, and the second drive gear 511 is fixedly installed on the output end of the steering motor 510.

[0043] The steering motor 510 is used to control the rotation of the second drive gear 511, and under the action of the second transmission gear 572, the fixed block 573 is rotated. When the clamping block 578 clamps one end of the tubular shell 6 and the fixed block 573 rotates, the tubular shell 6 is driven to rotate on the outer surface of the inner support column 43, thereby adjusting the orientation of the punching of the tubular shell 6, reducing the adjustment and positioning of the tubular shell 6, and improving the efficiency of punching the tubular shell 6.

[0044] like Figure 9 As shown, the internal support device 4 includes a first support frame 41, which is fixedly installed on the right side of the support platform 22, and a telescopic folding rod 42 is fixedly installed on the left side of the top of the first support frame 41, and an internal support column 43 is fixedly installed on the left end of the telescopic folding rod 42, and a second electric telescopic rod 419 is fixedly installed on the left side of the upper end of the first support frame 41, and the left end of the second electric telescopic rod 419 is fixedly connected to the internal support column 43, and a punching hole 44 is opened on the top of the internal support column 43, and the punching hole 44 is located below the punching drill bit in the punching machine body 1, and the internal support column 43 and the fixed block 573 are located between the two support bars 34, and the internal support column 43 is used to support the tubular shell 6 to avoid deformation and cracks in the tubular shell 6 during the stamping process.

[0045] Example 2, as Figure 1 , Figure 2 , Figure 9 - Figure 10As shown, an evaporator shell processing device is provided, wherein a cavity is opened at the left end inside the inner support column 43, and an inner support frame 45 is fixedly installed inside the cavity, a rotating motor 46 is fixedly installed at the lower end inside the inner support frame 45, and a first driving gear 47 is fixedly installed at the output end of the rotating motor 46, an auxiliary frame 48 is fixedly installed at the bottom of the cavity, a first transmission gear 49 is rotatably installed inside the auxiliary frame 48, the outer surface of the first transmission gear 49 is meshed with the outer surface of the first driving gear 47, a rotating rod 410 is fixedly installed on the top of the first transmission gear 49, the rotating rod 410 is rotatably installed on the top of the auxiliary frame 48, the outer surface of the rotating rod 410 is movably sleeved with a movable rod 414, a grinding roller 415 is fixedly installed on the top of the movable rod 414, and the grinding roller 415 is movably sleeved inside the stamping hole 44.

[0046] Among them, a lifting cylinder 412 is fixedly installed on one side of the top of the inner support frame 45, and a connecting plate 413 is fixedly installed on the output end of the lifting cylinder 412. The right end of the connecting plate 413 is rotatably installed on the outer surface of the lower end of the movable rod 414, and the outer surface of the upper end of the rotating rod 410 is fixedly installed with a limiting bar 411. The lower end of the movable rod 414 is movably connected to the outer surfaces of the rotating rod 410 and the limiting bar 411.

[0047] By setting the limit bar 411, the inside of the movable rod 414 is limited, and the movable rod 414 is controlled to rise and fall through the connecting plate 413 by utilizing the action of the lifting cylinder 412, so that the grinding roller 415 can be extended and retracted inside the punching hole 44. When the grinding roller 415 moves out of the punching hole 44, the grinding roller 415 is rotated by the control of the rotating motor 46, and the edge of the punched hole of the tubular shell 6 is polished, thereby reducing the burrs caused by the punching and improving the appearance quality of the shell and the assembly effect.

[0048] Among them, the upper end of the grinding roller 415 is movably sleeved with a movable block 416, the top of the movable block 416 is rotatably installed with a ball, the bottom of the movable block 416 is fixedly installed with a movable spring 417, the bottom of the movable spring 417 is fixedly installed on the bottom of the inner wall of the grinding roller 415, and the bottom of the inner wall of the grinding roller 415 is fixedly installed with a spring button 418, the lower end of the movable spring 417 is movably sleeved on the outer surface of the spring button 418, and the spring button 418 is electrically connected to the lifting cylinder 412 and the rotating motor 46 respectively.

[0049] By utilizing the function of the movable block 416, after the stamping machine body 1 punches a hole in the tubular shell 6, the punching drill bit of the stamping machine body 1 is buffered by the function of the movable spring 417 to prevent the punching drill bit from contacting the inside of the inner support column 43, causing damage to the inner support column 43 or the punching drill bit, and when the movable block 416 shrinks inside the grinding roller 415, the movable block 416 presses the spring button 418, thereby controlling the grinding roller 415 to grind the punched hole, so as to improve the quality of the punching hole and reduce the burrs generated by the punching hole.

[0050] Example 3, as Figure 1 - Figure 3 , Figure 6 - Figure 7 As shown, an evaporator shell processing device, the working base 2 includes a fixed base plate 21, a support platform 22 and a material guide pipe 23. The fixed base plate 21 is fixedly installed on the bottom of the stamping machine body 1, and the top of the fixed base plate 21 is fixedly installed on the support platform 22. A blanking port is opened on the top of the support platform 22. The interior of the fixed base plate 21 is fixedly installed on the material guide pipe 23. One end of the material guide pipe 23 is connected to the blanking port. The bottom of the material guide pipe 23 is an inclined surface. Two side brackets 31 are respectively fixedly installed on the top of the support platform 22 and are located at the left and right ends of the blanking port. The support bar 34 is movably installed above the blanking port.

[0051] By providing the guide tube 23 so that the bottom of the guide tube 23 is an inclined surface, when the tubular shell 6 is unloading, the internal expansion clamp 57 stops clamping one end of the tubular shell 6, and in the process of the first electric telescopic rod 56 controlling the sliding link 55 to move to the left, the stripping block 53 passes through the inside of the pushing groove 5712, and the stripping block 53 is used to push the tubular shell 6 off the outer surface of the internal expansion clamp 57, thereby preventing the internal expansion clamp 57 from affecting the unloading of the tubular shell 6. Under the action of the guide tube 23, the tubular shell 6 rolls down through the guide tube 23, thereby realizing automatic unloading and improving the processing efficiency of the tubular shell 6.

[0052] It should be noted that the present invention is an evaporator shell processing device. When in use, the tubular shell 6 is placed in the middle of the two support bars 34 and is sleeved on the outer surface of the inner support column 43. The first electric telescopic rod 56 is controlled to retract, so that the sliding link 55 moves to the right inside the sleeve block 54, so that the fixed block 573 is inserted into one end of the tubular shell 6. Subsequently, the clamping cylinder 574 controls the extrusion block 576 to retract into the inside of the fixed block 573. The push rod 577 is moved outward inside the fixed block 573 by using the inclined surface corresponding to the extrusion block 576. The clamping block 578 moves out of the fixed block 573, causing the clamping block 578 to expand inward and clamp one end of the tubular shell 6.

[0053] The sliding link 55 is controlled by the first electric telescopic rod 56 to move to the left inside the sleeve block 54, thereby adjusting the position of the tubular shell 6 on the outer surface of the punching hole 44, and then adjusting the position of the punching hole of the tubular shell 6. When the position of the punching hole of the tubular shell 6 is determined, the supporting cylinder 38 is extended to move the supporting bar 34 and the fixed rack 36, and push the rotating gear 37 to rotate. Under the action of the rotating gear 37, the fixed racks 36 at the two ends of the bottom of the side bracket 31 are moved toward each other, thereby moving the supporting bars 34 at both ends toward each other. The inclined surfaces on both sides of the top of the supporting bar 34 are used to support the bottom of the tubular shell 6. Under the action of the internal support column 43, the tubular shell 6 is supported and fixed. The stamping machine body 1 is operated to make the stamping drill punch the tubular shell 6.

[0054] During the punching process, after the punching drill punches the tubular shell 6, it contacts the top of the movable block 416, compressing the movable spring 417. The movable block 416 shrinks to the inside of the grinding roller 415, and the movable block 416 presses the spring button 418. Then, the punching drill moves out of the punching hole 44 and the inside of the tubular shell 6. At this time, the movable spring 417 uses the reaction force to make the movable block 416 push the punched fragments of the tubular shell 6 out of the inside of the punching hole 44. The lifting cylinder 412 and the rotating motor 46 then work. By utilizing the action of the lifting cylinder 412, the movable block 416 is connected to the inner wall of the punching hole 44. The plate 413 controls the movable rod 414 to rise, so that the grinding roller 415 moves out of the inner support column 43 through the punching hole 44. When the grinding roller 415 moves out of the inner support column 43, the first driving gear 47 drives the first transmission gear 49 and the rotating rod 410 to rotate under the control of the rotating motor 46. The movable rod 414 and the grinding roller 415 are driven to rotate by the limit bar 411, and the edge of the hole punched in the tubular shell 6 is polished. After polishing, the lifting cylinder 412 controls the grinding roller 415 to descend to the bottom of the punching hole 44 again, and the rotating motor 46 controls the grinding roller 415 to stop rotating.

[0055] When it is necessary to adjust the position of the punching hole of the tubular shell 6, the supporting cylinder 38 contracts to move the supporting bar 34 to both sides, and the first electric telescopic rod 56 is used to control the sliding link 55 to move inside the sleeve block 54, so that the internal expansion clamp 57 drives the tubular shell 6 to move on the outer surface of the inner support column 43, and the position of the punching hole of the tubular shell 6 is adjusted. When the steering motor 510 controls the second driving gear 511 to rotate, and under the transmission of the second driving gear 511 and the second transmission gear 572, the fixing block 573 is driven to rotate, and the fixing block 573 is used to clamp one end of the tubular shell 6, and the tubular shell 6 is rotated on the outer surface of the inner support column 43, so as to adjust the orientation of the punching hole of the tubular shell 6, thereby realizing punching holes in different positions and orientations of the tubular shell 6;

[0056] After the punching of the tubular shell 6 is completed, the supporting cylinder 38 controls the supporting bar 34 to move to both sides, the second electric telescopic rod 419 controls the telescopic folding rod 42 to retract, the inner support column 43 moves out of the interior of the tubular shell 6, and the internal expansion clamp 57 stops clamping one end of the tubular shell 6. In the process of the first electric telescopic rod 56 controlling the sliding link 55 to move to the left, the stripping block 53 passes through the inside of the pushing groove 5712, and the tubular shell 6 is pushed off the outer surface of the internal expansion clamp 57 by the stripping block 53. The supporting cylinder 38 continues to control the supporting bar 34 to move to both sides, and the tubular shell 6 falls to the inside of the blanking port by gravity, and under the action of the guide tube 23, the tubular shell 6 rolls down through the guide tube 23, realizing automatic unloading and improving the processing efficiency of the tubular shell 6.
