Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to an evaporator fin processing device. Background Technology

[0002] Fins are an important component of evaporators, primarily used to increase the heat exchange area and improve heat exchange efficiency. The fin design allows heat to be transferred to the fluid more quickly, thereby achieving a cooling or heating effect.

[0003] To increase the contact area between the fins and the fluid, the fins need to be bent according to the evaporator model. Currently, when placing the fins on the processing device, the position of the fin to be processed needs to be aligned with the abutment rod to reduce the error between the actual bending line and the theoretical bending line caused by improper fin placement, which would affect the processing efficiency of the processing device. Summary of the Invention

[0004] To improve the accuracy of material feeding, help workers ensure that the position to be processed is aligned with the abutment rod, and improve the processing efficiency of the processing device, this application provides an evaporator fin processing device.

[0005] The evaporator fin processing device provided in this application adopts the following technical solution: An evaporator fin processing device includes a frame and a receiving mechanism. The receiving mechanism includes a receiving sliding seat, a receiving plate, a receiving abutment seat, and a receiving slider. The receiving sliding seat is slidably connected to the frame, and the sliding direction of the receiving sliding seat is vertical. The receiving plate is connected to the upper end and is used for placing fins. The receiving abutment seat is connected to the receiving plate, and the side of the receiving abutment seat away from the frame is used to abut the surface of the fin close to the frame. The receiving slider is slidably connected to the receiving abutment seat, and the sliding direction of the receiving slider is vertical. The receiving slider is used to press against the upper surface of the fin.

[0006] By adopting the above technical solution, the fins are placed on the receiving plate, and the end of the fins near the frame is in contact with the receiving abutment, thereby achieving the positioning of the fins and improving the feeding accuracy of the workers; the receiving slider presses against the upper surface of the fins, reducing the possibility of the fins shifting during the upward movement of the receiving plate and improving the working efficiency of the processing device.

[0007] Preferably, it further includes a mounting base and abutment rods. The mounting base is slidably connected to the upper end of the frame, and the sliding direction of the mounting base is parallel to the length direction of the frame. There are two mounting bases, which are symmetrically distributed along the length direction of the frame. The number of receiving mechanisms and abutment rods is the same as the number of mounting bases and corresponds one-to-one. The receiving mechanism further includes a receiving fixed base and a receiving drive cylinder. The receiving fixed base is connected to one side of the mounting base along the width direction of the frame. The receiving drive cylinder is connected to the receiving fixed base and is used to drive the receiving sliding base to slide. One end of the abutment rod is connected to the side of the mounting base near the receiving fixed base, and the length direction of the abutment rod is perpendicular to the sliding direction of the mounting base.

[0008] By adopting the above technical solution, the abutment rod and the receiving mechanism are connected to the mounting base, and the two mounting bases are slidably connected to the frame, which facilitates the adjustment of the position of the two mounting bases, changes the distance between the two abutment rods, meets the requirements of different types of fins, and improves the applicability of the processing device.

[0009] Preferably, it further includes a sleeve and a fixing component. The abutting rod has an abutting ring on its outer periphery. The sleeve is sleeved on the outer periphery of the abutting rod. One end of the sleeve abuts against the abutting ring. The fixing component is connected to the abutting rod and is used to abut the end of the sleeve away from the abutting ring.

[0010] By adopting the above technical solution, the sleeve is fitted around the outer periphery of the abutment rod, reducing direct contact between the abutment rod and the fins, reducing the possibility of damage to the abutment rod, and improving the service life of the abutment rod; the abutment ring cooperates with the fixing component to achieve axial fixation of the sleeve and the abutment rod.

[0011] Preferably, the fixing assembly includes an abutment block, a third reset member, a connecting wire, a connecting plate, a fixing block, and a fourth reset member. The abutment plate has a groove on its outer periphery, and the abutment block is slidably embedded in the groove. The sliding direction of the abutment block is parallel to the radial direction of the abutment rod. The surface of the abutment block facing the abutment ring is in contact with the end of the sleeve away from the abutment ring. The third reset member is connected between the abutment rod and the abutment block, and the third reset member makes the abutment block tend to extend out of the groove. The end of the abutment rod away from the mounting base has a receiving groove for the connecting plate to be embedded. One end of the connecting wire is connected to the end of the abutment block facing the bottom of the groove, and the other end of the connecting wire is connected to the end of the connecting plate facing the bottom of the receiving groove. The fixing block is slidably connected to the connecting plate. The receiving groove has an annular groove on its wall for the fixing block to be embedded. The fourth reset member is connected between the fixing block and the connecting plate, and the fourth reset member makes the fixing block tend to be embedded in the annular groove.

[0012] By adopting the above technical solution, when installing the sleeve, pulling the fixing block causes it to overcome the elastic force of the fourth reset component and disengage from the annular groove. The connecting plate is then removed, and the connecting line is pulled, causing the abutment block to overcome the elastic force of the third reset component and embed into the groove. This facilitates the sleeve being fitted onto the outer circumference of the abutment rod. After the sleeve is installed and positioned, the connecting plate is embedded into the receiving groove. Under the action of the third reset component, the abutment block extends out of the groove and abuts against the end of the sleeve away from the abutment ring. The fixing component is then released, and under the action of the fourth reset component, it embeds into the annular groove, thus achieving axial fixation between the connecting plate and the abutment rod.

[0013] Preferably, the device further includes an adjustment mechanism, which comprises a rack, a meshing part, a ratchet, a pawl, a second reset member, and a turntable. The turntable is connected to the outer periphery of the sleeve near the abutment ring. The ratchet is coaxially rotatably connected to the outside of the turntable. One end of the pawl is hinged to the turntable, and the hinge axis between the pawl and the turntable is parallel to the axis of the abutment rod. The second reset member is connected between the pawl and the turntable, and the second reset member causes the other end of the pawl to tend to embed into the inner groove of the ratchet. The meshing part is coaxially connected to the outside of the ratchet. The lower end of the rack is connected to the receiving abutment seat, and the rack meshes with the meshing part.

[0014] By adopting the above technical solution, when the receiving plate slides, it drives the rack to slide, drives the meshing part to rotate, drives the ratchet to rotate, and when the pawl presses against the inner groove wall of the ratchet, it drives the turntable to rotate, thereby realizing the rotation of the sleeve. This enables the sleeve to automatically adjust the contact surface with the fins, making the circumferential wear of the sleeve uniform and improving the service life of the sleeve.

[0015] Preferably, a limiting block is connected to the outer periphery of one end of the sleeve near the abutment ring, and a limiting groove is provided on the inner side of the turntable for the limiting block to be embedded in. The side wall of the limiting block fits against the groove wall of the limiting groove.

[0016] By adopting the above technical solution, the limiting block is embedded in the limiting groove to achieve circumferential fixation of the sleeve and the turntable, which helps the turntable drive the sleeve to rotate and facilitates the installation and disassembly of the sleeve and the turntable.

[0017] Preferably, the system further includes a bending mechanism, which comprises a bending fixed seat, a bending sliding seat, a bending plate, and a bending drive cylinder. The bending fixed seat is coaxially rotatably connected to the abutment rod, the bending sliding seat is slidably connected to the bending fixed seat, and the sliding direction of the bending sliding seat is vertical. The bending drive cylinder is connected to the bending fixed seat and is used to drive the bending sliding seat to slide. The bending plate is connected to the upper end.

[0018] By adopting the above technical solution, the driving component works, driving the active gear to rotate, driving the driven gear to rotate, driving the connecting cylinder to rotate, driving the connecting rod to rotate, driving the bending fixing seat to rotate, and thus driving the bending plate to abut against the side of the fin away from the abutting rod, thereby realizing the bending of the fin and helping to improve the bending stability of the equipment.

[0019] Preferably, the bending mechanism further includes a limiting component, which includes an adjusting seat, an adjusting block, and an adjusting bolt. One end of the adjusting seat is connected to the side of the bending plate away from the receiving plate. The adjusting block is slidably connected to the upper end of the adjusting seat. The sliding direction of the adjusting block is perpendicular to the axial direction of the abutment rod. The side surface of the adjusting block facing the bending plate is used to fit against the side wall of the fin. The adjusting bolt is used to connect the adjusting block and the adjusting seat.

[0020] By adopting the above technical solution, the fins are positioned by the adjustment block fitting against the side wall of the fin, preventing the fins from shifting during bending and improving the working efficiency of the processing device. The adjustment block is slidably connected to the adjustment seat, and the adjustment bolt connects the adjustment block and the adjustment seat, meeting the needs of fins of different sizes and improving the applicability of the processing device.

[0021] Preferably, the end of the adjusting block away from the frame is provided with a first chamfer, and the first chamfer is located on the side of the adjusting block near the bending plate.

[0022] By adopting the above technical solution, the first chamfer guides the fins, making it easier for workers to place the fins in the designated area and improving work efficiency.

[0023] Preferably, the adjusting seat is provided with an adjusting groove, the adjusting groove extends along the sliding direction of the adjusting block, the adjusting block is provided with an insert, the insert is slidably embedded in the adjusting groove, and the side walls of the insert perpendicular to the sliding direction of the insert are in contact with the groove wall of the adjusting groove.

[0024] By adopting the above technical solution, the insert is slidably embedded in the adjustment groove, the adjustment groove ensures that the support block moves along the length direction of the adjustment groove, the side wall of the insert is in contact with the groove wall of the adjustment groove, and ensures that the side surface of the adjustment block facing the fin remains parallel to the side wall of the fin.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The fins are placed on the receiving plate, with the end of the fin closest to the frame fitting against the receiving abutment to position the fins and improve the feeding accuracy of the operator; the receiving slider presses against the upper surface of the fins to reduce the possibility of the fins shifting during the upward movement of the receiving plate and improve the working efficiency of the processing device. 2. When the receiving plate slides, it drives the rack to slide, which in turn drives the meshing part to rotate and the ratchet to rotate. When the pawl presses against the inner groove wall of the ratchet, it drives the turntable to rotate, thereby realizing the rotation of the sleeve. This allows the sleeve to automatically adjust its contact surface with the fins, resulting in uniform circumferential wear of the sleeve and improving its service life. 3. When the drive unit operates, it drives the drive gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the connecting cylinder to rotate, which in turn drives the connecting rod to rotate, which in turn drives the bending fixing seat to rotate. This causes the bending plate to abut against the side of the fin away from the abutting rod, thereby achieving the bending of the fin and helping to improve the bending stability of the equipment.

The bending plate 58 is fixedly connected to the upper end of the bending sliding seat 57, and the bending plate 58 is used to abut against the surface of the fin away from the sleeve 32.

[0047] The bending mechanism 5 also includes a limiting component 50. The limiting component 50 includes an adjusting seat 501 and an adjusting block 502. One end of the adjusting seat 501 is fixedly connected to the side of the bending sliding seat 57 away from the receiving sliding seat 22, and the length direction of the adjusting seat 501 is parallel to the length direction of the frame 11. The adjusting block 502 is slidably connected to the upper end of the adjusting seat 501, and the sliding direction of the adjusting block 502 is parallel to the length direction of the adjusting seat 501. The side surface of the adjusting block 502 facing the bending plate 58 is used to fit against the side wall of the fin. The side surface of the adjusting block 502 facing the bending plate 58 is provided with a first chamfer 5021. The first chamfer 5021 is located on the side of the adjusting block 502 away from the frame 11, and the first chamfer 5021 is used for the side wall of the fin facing the frame 11 to abut.

[0048] The limiting assembly 50 also includes an adjusting bolt 503. The adjusting seat 501 has an adjusting groove 5011 extending along its length. The lower end of the adjusting block 502 has an insert 5022, which is slidably embedded in the adjusting groove 5011. The sidewalls of the insert 5022 along the width direction of the adjusting seat 501 are in contact with the groove wall of the adjusting groove 5011. The adjusting bolt 503 connects the adjusting seat 501 and the adjusting block 502. In this embodiment, the head of the adjusting bolt 503 abuts against the lower end of the adjusting seat 501, and the shank of the adjusting bolt 503 extends into the adjusting groove 5011 and is threadedly connected to the insert 5022.

[0049] The implementation principle of the evaporator fin processing device in this application embodiment is as follows: the first motor 13 works, drives the lead screw 14 to rotate, drives the mounting base 12 to slide to the designated position, loosens the adjusting bolt 503, slides the adjusting block 502 to the designated position, tightens the adjusting bolt 503, and fixes the adjusting block 502 and the adjusting base 501.

[0050] The fins are placed on the receiving plate 23, and the fins abut against the first chamfer 5021, so that the sidewall of the fins fits against the side surface of the adjusting block 502 facing the bending plate 58.

[0051] The fins move towards the frame 11, and the end of the fins near the frame 11 abuts against the second chamfer 251, causing the receiving slider 25 to slide away from the receiving plate 23. When the surface of the fins near the frame 11 is in contact with the bottom of the groove 241, the receiving slider 25 presses against the upper surface of the fins under the action of the first reset member 26, thereby realizing the feeding of the fins.

[0052] The receiving drive cylinder 27 operates, causing the receiving sliding seat 22 to move upward, which in turn moves the receiving plate 23 upward, causing the fins to move upward and press against the outer wall of the sleeve 32. The bending drive cylinder 59 operates, causing the bending sliding seat 57 to move upward, which in turn moves the bending plate 58 upward, so that the bending plate 58 abuts against the side of the fin away from the sleeve 32. The drive component 51 operates, causing the drive gear 52 to rotate, which in turn rotates the driven gear 53, which in turn rotates the connecting cylinder 54, which in turn rotates the connecting rod 55, which in turn rotates the bending fixing seat 56, which in turn rotates the bending sliding seat 57, thus driving the bending rotation and achieving the bending of the fins.

[0053] After bending is completed, the drive component 51 operates, causing the bending assembly to reset. The receiving drive cylinder 27 operates, causing the receiving plate 23 to move downward, which in turn causes the rack 41 to move downward, causing the meshing part 42 to rotate, which in turn causes the ratchet 43 to rotate. The inner groove 431 of the ratchet 43 abuts against the ratchet 43, causing the pawl 44 to rotate, which in turn causes the turntable 46 to rotate, and in turn causes the sleeve 32 to rotate.

[0054] When the sleeve 32 needs to be replaced, squeeze the two fixing blocks 335 so that they move closer together, causing the fixing part 3352 to disengage from the annular groove 314 and the connecting plate 334 to disengage from the receiving groove 313. Pull the abutment block 331, which overcomes the third reset member 332 and disengages from the embedded groove 312, allowing the sleeve 32 to be removed. Then, insert the connecting plate 334 into the receiving groove 313, loosen the fixing member, and allow the fixing part 3352 to embed into the annular groove 314, thus fixing the connecting plate 334 and the abutment rod 31.

[0055] Slide the sleeve 32 along the axis of the abutment rod 31. The end of the sleeve 32 near the abutment ring 311 abuts against the third chamfer 3311, so that the abutment block 331 overcomes the third reset member 332 and disengages from the embedded groove 312. After the sleeve 32 abuts against the limiting ring, the limiting block 321 is embedded in the limiting groove 461, so as to achieve circumferential fixation between the sleeve 32 and the turntable 46. Under the action of the third reset member 332, the abutment block 331 extends out of the groove 312 and abuts against the end of the sleeve 32 away from the abutment ring 311.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
