Description

Technical Field

[0001] This invention belongs to the field of condenser manufacturing technology, specifically relating to an integrated processing equipment and method for condenser tube ends. Background Technology

[0002] In the production process of condensers (such as those used in household and automotive air conditioning systems), condensers typically consist of multiple layers of stacked fins and multiple copper tubes threaded through the fins. During the processing of the tube ends and fins, the copper tube openings need to be flared (to facilitate subsequent welding of connectors or bends). Simultaneously, the edges of the stacked fins need to be cut, and the outer right-angled edges formed by the stacked fins need to be chamfered to create clearance notches and chamfers at bending points, allowing subsequent processes to bend and shape the condenser as a whole. Traditional processing methods typically employ multiple offline devices for decentralized processing, which has the following drawbacks: 1. Large secondary positioning error: Fin cutting, right-angle chamfering, and copper tube flaring are performed on different devices, requiring frequent transfer and repositioning of the condenser, which can easily lead to deviations in the cut position and affect the quality of subsequent bending and welding; 2. Low processing efficiency: Manual multi-step loading and unloading consumes a lot of time and cannot meet the pace of highly automated production; 3. Easy demolding and deformation when flaring: When flaring copper tubes, the flaring punch is tightly fitted to the inner wall of the copper tube. When the flaring device is pulled upwards, the huge pulling friction can easily pull the copper tube and fins upwards or deform them; 4. Difficult quick disassembly and replacement: The number and spacing of copper tubes vary for different specifications of condensers. The disassembly and assembly of the flaring device (punch) of the traditional flaring assembly are extremely cumbersome and the replacement cost is high. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated processing equipment and method for condenser tube ends, which aims to solve the problems of scattered processing steps, large secondary positioning errors, easy deformation of workpieces due to flaring and unloading, and cumbersome replacement of flaring devices in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A condenser tube-end integrated processing device is disclosed. The condenser includes several stacked fins and several copper tubes passing through the fins. The processing device includes a frame with a product fixing base for supporting the condenser. A door positioning assembly that can be opened and closed is provided on the front side of the frame. The door positioning assembly is equipped with a clamping cylinder for pressing and fixing the condenser to the product fixing base in the closed state. A cutting and chamfering assembly is also installed on the frame. The cutting and chamfering assembly is driven by a cutting and chamfering power motor provided on the frame and can move up and down in the vertical direction. The cutting and chamfering assembly is equipped with a cutter and a chamfering roller that can be fed independently and alternately. The cutter is used to cut the edges of the stacked fins, and the chamfering roller is used to chamfer the right angle edges formed after the fins are stacked. A flaring assembly is provided on the frame and above the product fixing base. The flaring assembly includes a flaring cylinder that drives the flaring device downward into the copper tube opening, and a material ejection mechanism for pressing the condenser downward when the flaring cylinder drives the flaring device to retract upward.

[0006] Furthermore, the cutting and chamfering assembly includes a crossbeam, and a cutting cylinder and a chamfering cylinder mounted on the crossbeam. The cutting blade is mounted on the output end of the cutting cylinder, and the chamfering roller is mounted on the output end of the chamfering cylinder. In the cutting condition, the cutting cylinder drives the cutting blade to extend onto the processing trajectory of the fin. In the chamfering condition, the chamfering cylinder drives the chamfering roller to extend onto the processing trajectory of the right-angled edge of the stacked fin.

[0007] Furthermore, the unloading mechanism includes an unloading cylinder fixed to the flaring assembly and an unloading pressure plate connected to the output end of the unloading cylinder; the unloading pressure plate is sleeved on the flaring device; after the flaring cylinder drives the flaring device to rush into the copper tube opening to complete the flaring, the unloading cylinder drives the unloading pressure plate downward to press against the upper end face of the condenser, and while the unloading pressure plate remains pressed against the condenser, the flaring cylinder drives the flaring device upward to pull out the copper tube opening.

[0008] Furthermore, the flaring assembly is mounted on a slide, which is driven by a lifting drive mechanism mounted on the frame to move up and down in the vertical direction; the flaring cylinder is mounted and fixed on the slide; the output end of the flaring cylinder is connected to a fixing plate; the ejector cylinder is mounted on both ends of the fixing plate.

[0009] Furthermore, the flaring assembly includes, from top to bottom, a switching plate, a middle plate, and a locking plate. The switching plate is located below the fixed plate, and under the action of the switching cylinder mounted on the fixed plate, the switching plate can move back and forth between the blocking position and the passing position in the horizontal direction relative to the fixed plate. The switching plate, the middle plate, and the locking plate are all provided with arrayed through holes. The through holes of the locking plate are equipped with locking pins and locking springs. The upper end of the flaring device passes through the through holes in the locking plate and the middle plate. When the switching plate is in the blocking position, the corresponding through holes of the switching plate and the middle plate are misaligned to prevent the flaring device from moving upward. The upper end of the flaring device is provided with a locking groove with a sloping bottom surface. Under the action of the locking spring, the locking pin is engaged in the locking groove to prevent the flaring device from moving downward. When the switching plate is in the passing position, the through holes of the switching plate and the middle plate are coaxially aligned, pushing the flaring device upward. The bottom surface of the locking groove acts on the locking pin to make it leave the through hole of the locking plate. Rotating the flaring device makes the locking groove and the locking pin misaligned and can disengage from the locking plate.

[0010] Furthermore, a connecting plate is connected to the side of the switching plate, and the connecting plate extends upward and is fixedly connected to the cylinder shaft of the switching cylinder.

[0011] Furthermore, the lifting drive mechanism includes a flaring assembly adjustment motor located on the top of the frame and a column guide rail located on the frame. The slide is slidably mounted on the column guide rail via a screw and nut pair. The flaring assembly adjustment motor is used to drive the slide and the flaring assembly to move up and down as a whole to adjust the initial processing height.

[0012] Furthermore, the door panel positioning assembly includes a door panel rotatably connected to the front side of the frame via a hinge mechanism, and a locking handle disposed on the door panel. Four sets of clamping cylinders are disposed on the upper and lower sides of the door panel respectively, for pressing against the condenser fins and sides from the front.

[0013] Furthermore, the locking handle includes a handle rotatably mounted on the door panel, a latch slidably mounted inside the door panel or in a fixed seat, and a return spring located at the rear end of the latch. The front end of the latch is provided with a wedge-shaped bevel, and the front side of the frame is correspondingly provided with a buckle seat having a bevel guide and a locking groove. The lower end of the handle is linked with the latch, and the return spring is used to provide a preload force to keep the latch from popping outward and engaging in the locking groove. When the door panel is closed, the wedge-shaped bevel is compressed back along the bevel guide of the buckle seat, and pops out and locks under the action of the return spring after entering the locking groove. When the handle is pulled, the handle overcomes the elastic force of the return spring and drives the latch to retract inward and disengage from the locking groove to unlock.

[0014] The present invention also provides a method for processing condenser tube ends, using the above-mentioned integrated condenser tube end processing equipment, including the following steps:

[0015] S1. Place the condenser with copper tubes and stacked fins on the product fixing base, close the door panel positioning component, and control the clamping cylinder to extend and clamp the condenser in position.

[0016] The control cylinder drives the cutter to extend to its position, and the cutting and chamfering motor drives the cutting and chamfering assembly to move downward, using the cutter to cut the edges of the stacked fins; after cutting, the cutter cylinder drives the cutter to retract to its original position, and the cutting and chamfering motor drives the cutting and chamfering assembly to move upward to reset to its high position;

[0017] S3. Control the chamfering cylinder to drive the chamfering roller to extend to the position, and the cutting chamfering power motor drives the cutting chamfering assembly to move downward again. Use the chamfering roller to chamfer the right angle edge formed after the fins are stacked. After the chamfering is completed, the chamfering cylinder drives the chamfering roller to retract to the position, and the cutting chamfering power motor drives the cutting chamfering assembly to move upward to reset to the high position.

[0018] S4. The flaring cylinder drives the flaring tool to extend downwards and plunge into the copper tube opening to complete the flaring.

[0019] S5. The unloading cylinder extends downward and presses against the upper end face of the condenser. While the unloading cylinder is pressed, the flaring cylinder drives the flaring device to retract upward to remove the copper tube opening. Then the unloading cylinder retracts back to its original position.

[0020] S6. All components return to their original position, the clamping cylinder is released, the door panel positioning component is opened, and the processed condenser is removed for use in subsequent bending processes.

[0021] This invention offers the following advantages: 1. High precision through integrated design: By integrating the stacked fin trimming, stacked right-angle chamfering, and copper tube flaring height into a single device and under the same benchmark, it avoids the accumulation of errors from multiple positioning operations, significantly improving the quality of subsequent bending and welding. 2. Active anti-pull-out ejection: Through the ejection cylinder and ejection pressure plate, the ejector is pre-pressed against the upper surface of the condenser fins when the flaring device is pulled upwards from the copper tube opening, effectively counteracting the huge upward pulling force and preventing the copper tube from being pulled off and damaged. 3. Plug-in quick-release locking: By using a switching cylinder to control the switching plate to move between the "blocking position" and the "passing position," and in conjunction with the locking pin with an inclined locking groove, the flaring device can be quickly unlocked and removed for replacement, greatly reducing downtime for mold changes.

[0033] As attached Figure 1 As shown, this embodiment provides an integrated processing equipment for condenser tube ends. Its overall frame is constructed of heavy-duty steel, and a product fixing base 11 is fixedly installed on the frame to support the condenser to be processed. The condenser to be processed consists of multiple layers of parallel stacked fins and multiple copper tubes threaded and connected in series on each layer of fins. The top surface shape of the product fixing base 11 matches the lower side frame and pipe outline of the condenser to provide a stable and flat support reference.

[0034] A door panel positioning assembly 2, capable of rotating and opening / closing left and right, is installed on the front side of the frame. For example... Figure 7 and attached Figure 8As shown, the door panel positioning assembly 2 includes a door panel 21 hinged to the front side of the frame via a hinge mechanism. Four sets of clamping cylinders 22 are distributed on the door panel 21, located at the upper left, upper right, lower left, and lower right corners, with the piston rods of the cylinders facing the product fixing base 11. A locking handle 23 is installed on the outer side of the door panel 21. The locking handle 23 consists of a handle 231 rotatably connected to the door panel 21, a locking tongue 232 slidably disposed within the fixing base, and a return spring 233 sleeved on the rear end of the locking tongue 232. The front end of the locking tongue 232 is machined with a wedge-shaped bevel, and a latch 122 with a beveled guide portion 121 and a locking groove is fixed at a position on the front side of the frame corresponding to the locking tongue 232. When the operator pushes the door panel 21 closed, the wedge-shaped inclined surface of the latch 232 slides along the inclined guide portion 121 of the latch seat and retracts into the door panel 21, while simultaneously compressing the return spring 233. When the door panel 21 is fully closed, the latch 232 aligns with the locking groove and, under the elastic force of the return spring 233, pops out and engages in the locking groove, thus achieving automatic mechanical locking of the door panel 21. When unlocking is required, pulling the handle 231 will overcome the spring force through the linkage mechanism, pulling the latch 232 back and disengaging it from the locking groove. With the door panel 21 locked, the four sets of clamping cylinders 22 are activated, their piston rods extend and press against the condenser fins and sides from the front, thereby firmly fixing the condenser to the product fixing base 11.

[0035] A cutting and chamfering assembly 3, driven by a cutting and chamfering power motor 13, is mounted on the frame and above the product fixing base 11. The cutting and chamfering power motor 13 drives the entire cutting and chamfering assembly 3 to perform precise up-and-down lifting movements in the vertical direction via a vertically arranged lead screw and nut pair. Figure 9 and attached Figure 10 As shown, the cutting and chamfering assembly 3 includes a crossbeam 31, on which a cutting cylinder 32 and a chamfering cylinder 33 are mounted side by side. The output end of the cutting cylinder 32 is equipped with a cutting blade 34 for cutting notches in the fins, and the output end of the chamfering cylinder 33 is equipped with a chamfering roller 35 for chamfering right-angle edges. The cutting cylinder 32 and the chamfering cylinder 33 can be controlled independently. During the cutting operation, the cutting cylinder 32 drives the cutting blade 34 to extend outwards onto the side cutting trajectory of the stacked fins, and the cutting and chamfering motor 13 drives the cutting blade 34 to move downwards, cutting the required local notches on the edges of the stacked fins. During the chamfering operation, the cutting cylinder 32 retracts, and the chamfering cylinder 33 drives the chamfering roller 35 to extend to the position of an outer long strip of right-angle edge formed by the stacking of layers of fins. The cutting and chamfering motor 13 drives the chamfering roller 35 to move downwards along this right-angle edge to perform chamfering cutting (such as chamfering a bevel or arc). The chamfering of the stacked fin cuts and right-angled edges provides ample space for deformation avoidance during the subsequent bending process of the entire condenser, preventing the fins from being squeezed, deformed, or damaged during bending.

[0036] like Figure 2 To be continued Figure 4 As shown, a column guide rail is fixed on the column at the top of the frame, and the slide block 14 is slidably mounted on the column guide rail via a screw and nut pair. A flaring assembly adjustment motor 15 is installed at the top of the frame. The flaring assembly adjustment motor 15 can drive the slide block 14 to move up and down along the column guide rail, which is used to adjust the initial processing height of the flaring assembly according to the length of different specifications of condensers. A flaring cylinder 41 is fixedly installed on the slide block 14. The piston rod of the flaring cylinder 41 extends downward and is fixedly connected to a fixing plate 42. Unloading cylinders 43 are fixedly installed at both ends of the fixing plate 42. The unloading mechanism also includes an unloading pressure plate 44 connected to the output end of the unloading cylinder 43. The unloading pressure plate 44 is sleeved on the flaring tool 16, and the unloading pressure plate 44 has a clearance through hole for the flaring tool 16 to pass through. After the flaring cylinder 41 drives the flaring tool 16 to extend into the openings of the copper tubes in the condenser and complete the flaring action, due to the large frictional force between the flaring tool 16 punch and the inner wall of the copper tube, the ejector cylinder 43 starts first, driving the ejector plate 44 to extend downward and firmly press against the upper end face of the condenser. While the ejector plate 44 is pressing downward, the flaring cylinder 41 starts again and drives the flaring tool 16 to be pulled upward away from the opening of the copper tube. The downward pressure applied by the ejector plate 44 counteracts the pulling force when the flaring tool 16 is pulled upward, thus completely avoiding the situation where the copper tube and fins are pulled and deformed.

[0037] The flaring assembly also features a quick-release locking structure. Specifically, a switching plate 45, a middle plate 46, and a locking plate 47 are arranged sequentially from top to bottom below the fixing plate 42. A switching cylinder 48 is mounted on the fixing plate 42. A connecting plate 49 is fixedly connected to the side of the switching plate 45. The connecting plate 49 extends upward and is fixedly connected to the piston rod of the switching cylinder 48. The switching cylinder 48 can drive the switching plate 45 to switch back and forth between the blocking position and the passing position in the horizontal direction relative to the fixing plate 42. Through holes arranged in an array are provided on the switching plate 45, the middle plate 46, and the locking plate 47. A locking pin 471 and a locking spring 472 are fitted on the inner side wall of the through hole of the locking plate 47. The upper end of the flaring tool 16 passes through the through holes on the locking plate 47 and the middle plate 46. A locking groove 161 with a sloping bottom surface is provided on the side wall of the head of the flaring tool 16.

[0038] When the switching cylinder 48 pushes the switching plate 45 to the blocking position (e.g.) Figure 5As shown), the through holes on the switching plate 45 and the middle plate 46 are offset. The solid part of the switching plate 45 blocks directly above the head of the flaring tool 16, preventing the flaring tool 16 from moving upward. At the same time, under the elastic force of the locking spring 472, the locking pin 471 is engaged in the locking groove 161 of the flaring tool 16. The inclined bottom surface of the locking groove 161 cooperates with the locking pin 471 to prevent the flaring tool 16 from falling downward. Thus, the flaring tool 16 is locked in both directions between the locking plate 47 and the middle plate 46, enabling it to withstand high-intensity stamping flaring force. When it is necessary to replace the flaring tool 16, the switching cylinder 48 pulls the switching plate 45 to the pass position (e.g., Figure 6 As shown in the diagram, at this time, the through hole on the switching plate 45 is coaxially aligned with the through holes on the middle plate 46 and the locking plate 47. At this time, push the flaring device 16 upward, and the flaring device 16 enters the through hole of the switching plate 45. During this process, the inclined bottom surface of the locking groove 161 presses against the locking pin 471, overcoming the spring force and pushing the locking pin 471 back into the side hole of the locking plate 47. Then, rotate the flaring device 16 clockwise or counterclockwise to make the locking groove 161 and the locking pin 471 axially misaligned, so that the locking pin 471 can no longer fall into the locking groove 161. At this time, the flaring device 16 can be smoothly pulled down vertically to disengage from the locking plate 47, realizing the quick disassembly and replacement of the flaring device 16.

[0039] This embodiment provides a method for integrated processing of condenser tube ends using the aforementioned equipment. The entire process flow is as follows:

[0040] The first step is the clamping and positioning process. The operator places the condenser, with the copper tubes and stacked fins, flat on the product fixing base 11. Then, the operator pushes the door panel positioning assembly 2 to close. The locking tongue 232 at the locking handle 23 retracts along the inclined guide portion 121 of the buckle and pops out after entering the locking groove, completing the mechanical pre-locking of the door panel 21. Immediately afterwards, the control system activates four sets of clamping cylinders 22. The piston rods of the four sets of clamping cylinders 22 extend simultaneously, pressing the condenser fins and sides evenly and flatly onto the product fixing base 11 from the front, achieving precise positioning of the condenser.

[0041] After positioning is completed, the fin cutting process is executed. The control system first drives the cutter cylinder 32 to extend, pushing the cutter 34 onto the cutting trajectory on the side of the stacked fins of the condenser. Then, the cutting and chamfering motor 13 is started, driving the entire cutting and chamfering assembly 3 to move downwards at a constant speed in the vertical direction to the processing position. The cutter 34 is used to cut notches on the edges of the stacked fins. After cutting, the cutter cylinder 32 retracts back to its original position, and the cutting and chamfering motor 13 rotates in the opposite direction to drive the cutting and chamfering assembly 3 to rise back to its initial high position. The control system drives the chamfering cylinder 33 to extend, pushing the chamfering roller 35 to the position of the outer long strip right angle edge formed after the fins are stacked. The cutting and chamfering motor 13 drives the cutting and chamfering assembly 3 to move downwards again, using the chamfering roller 35 to cut and chamfer the right angle edge, forming a bending avoidance angle for subsequent bending processes. After chamfering is completed, the chamfering cylinder 33 retracts back to its original position, and the cutting and chamfering motor 13 drives the cutting and chamfering assembly 3 to rise back to its initial high position again.

[0042] Next, the stamping and flaring process is performed. The flaring cylinder 41 is activated and drives the fixing plate 42 and the flaring device 16 to extend downward at high speed. The punch of the flaring device 16 is inserted into the opening of each copper tube and expands it to the predetermined inner diameter of the interface.

[0043] Immediately after flaring, the clamping and unloading process is executed. The unloading cylinder 43 extends downwards first, driving the unloading pressure plate 44 to firmly press against the upper surface of the condenser. While the unloading cylinder 43 continues to press downwards, the flaring cylinder 41 activates and drives the flaring tool 16 to retract upwards to remove the copper tube opening. During this process, the upper surface of the condenser is continuously restricted by the unloading pressure plate 44, effectively preventing the copper tube and fins from being pulled upwards and deformed along with the flaring tool 16. After the flaring tool 16 is completely removed from the copper tube opening, the unloading cylinder 43 retracts back to its original position.

[0044] Each cylinder retracts to its original position; the four sets of clamping cylinders 22 retract and release the pressure on the condenser; the operator pulls the handle 231, which overcomes the spring force of the return spring 233 and drives the locking tongue 232 to retract and disengage from the locking seat 122, opening the door panel 21, taking out the condenser semi-finished product with the bending clearance and flared tube end, and sending it to the next bending process.
