Description

Technical Field

[0001] The present invention relates to the technical field of evaporators, and in particular to continuous processing equipment and a processing method thereof for industrial air-conditioning heat exchanger components. Background Art

[0002] In the production process of evaporators in industrial air-conditioning units, it is necessary to butt and weld the long U-shaped tube and the short U-shaped tube after pipe threading to ensure the sealing of the refrigerant flow in the tube. Therefore, it is necessary to ensure that the shape of the interface of the U-shaped tube is intact. Patent announcement No. CN115647823A discloses a U-shaped tube processing system for a dryer heat exchanger, including a bending component, a lifting mechanism, a fixing component, a grinding component, a feeding component, a cutting component, a unloading component, a positioning component and a receiving component; the feeding component is used for intermittent feeding of tube materials, and the feeding component includes a wedge part, a rubber strip, a feeding seat and a feeding wheel. The feeding seat drives the wedge part to move up and down by reciprocating movement. The wedge part is connected to the rubber strip. The rubber strip and the feed wheel feed or reset the tube material relative to each other by clamping or releasing the tube material; the positioning component is arranged on one side of the feeding component, and the positioning component is used to position the fed tube material.

[0003] In the above technical solution, the U-shaped tube is bent and cut. However, due to the short length of the short U-shaped tube itself, both its interfaces are adjacent to the bending part, which makes deformation inevitable during the bending process, especially at the cut interface. This deformation will cause a gap when docking with the subsequent long U-shaped tube, resulting in leakage of the evaporator after welding. In order to avoid the above situation, after the bending process, the U-shaped tube interface is usually shaped to ensure the quality of its interface shape. This process requires the cut U-shaped tube to be placed on a vibrating loading tray, so that a large number of U-shaped tubes are sorted and loaded into the shaping machine, and the shaping machine then shapes the interfaces in turn. However, this additional shaping process will undoubtedly waste a lot of time, equipment and labor costs.

[0004] Therefore, there is an urgent need for a U-tube bending and shaping integrated technical solution to solve the above problems. Summary of the Invention

In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application.

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0041] See also Figure 1-9 The present invention provides a technical solution: a continuous processing device and a processing method for industrial air-conditioning heat exchanger components, comprising a feeding table 5, a bending component and a shaping component.

[0042] The bending assembly includes at least one rotatable bending die 2, a bending groove is provided on the surface of the bending die 2, and the bending die 2 rotates around the axis of the bending groove. One end of the bending die 2 is fixedly connected to a square seat 201, and one end of the square seat 201 is fixedly connected to a fixed insertion rod 202. A slit 203 is provided at the junction of the bending die 2 and the square seat 201, and a pressure rod groove 204 is provided at the other end of the square seat 201.

[0043] A movable support base 3 is provided on the lower side of the bending die 2, and a rod slot is provided on the support base 3;

[0044] The shaping component includes a movable insertion rod 1 that can be raised and lowered, a pushing hole is opened through the inner side of the bending die 2, a pushing rod 205 is arranged in the pushing hole, and a stepped opening 207 is arranged at one end of the pushing hole. The upper end of the movable insertion rod 1 is fixedly connected to the translation seat 101, and the two ends of the translation seat 101 are fixedly connected to the trapezoidal wedge block 105 and the trapezoidal wedge block 2 106. An increasing block is provided on one side of the movable insertion rod 1, and the lower end of the increasing block is fixedly connected to the limit block 107. The lower end of the limit block 107 is provided with an inclined surface, which is adapted to the trapezoidal wedge block 2 106.

[0045] A cutting notch is formed between the feeding table 5 and the support seat 3, and the cutting notch is adapted to the cutting seam 203. A rotary cutter 7 is provided in the cutting notch. The rotary cutter 7 is driven to rotate by the motor assembly. The rotary cutter 7 and the motor assembly are driven to move horizontally by a linear drive mechanism.

[0046] The heat exchange tube body 6 is axially transported by the feeding platform 5. A rod groove is provided on the upper side of the feeding platform 5. The rod groove is adapted to the heat exchange tube body 6. An adaptation groove 501 is provided at the end of the feeding platform 5 (the axial transport of the heat exchange tube body 6 is a prior art, so it will not be described in detail here); Figure 5As shown, when the bending die 2 is in the initial state, the head end of the heat exchange tube body 6 enters the support seat 3 and is inserted into the outer side of the fixed insertion rod 202, thereby limiting and fixing the head end; then, the bending die 2 is rotated with the axis of the bending groove as the center, and the heat exchange tube body 6 is fed accordingly. Under the limiting action of the support seat 3, the heat exchange tube body 6 gradually fits on the bending groove until the bending die 2 rotates 180 degrees. The pressure rod groove 204 at one end of the square seat 201 presses the subsequent heat exchange tube body 6 tightly against the end of the feeding table 5 (as shown in FIG. Figure 4 As shown), the bending is completed, and an uncut U-shaped tube body 601 is formed on the bending die 2; the U-shaped tube body 601 is cut off separately by moving the rotary cutter 7 along the cutting edge and the slit 203; then the bending die 2 and the fixed insert 202 drive the U-shaped tube body 601 to rotate 90 degrees in the opposite direction (as shown Figure 3 As shown in the figure), to avoid interference, the heat exchange tube body 6 can be moved back to avoid it accordingly, so that the interface of the U-shaped tube body 601 faces upward, and then the movable insertion rod 1 is lowered and inserted into the incision of the U-shaped tube body 601 to complete the shaping. After bending and cutting, the shaping process can be directly connected, saving the time of the U-shaped tube body 601 process turnover and sorting. The bending die 2 is used to achieve bending and further fix the position of the U-shaped tube body 601. There is no need to re-position the U-shaped tube body 601, and the shaping can be carried out, thereby improving the processing convenience. In addition, a support seat 3 is provided, which cooperates with the bending die 2 to complete the bending of the U-shaped tube body 601 and cooperates with the movable insertion rod 1 to support the U-shaped tube body 601 during the shaping work, thereby improving the shaping stability.

[0047] When the shaping is completed and the U-shaped tube body 601 needs to be unloaded, the support seat 3 is displaced to one side, so that the U-shaped tube body 601 loses its support and can be dropped down. However, since one interface card of the U-shaped tube body 601 is inserted into the fixed insertion rod 202, there is friction between the two. Therefore, when unloading, it is difficult to stably drop the material by relying solely on the weight of the U-shaped tube body 601 itself. Therefore, a push rod 205 is provided on the inner side of the bending die 2. When unloading is required, the push rod 205 is displaced downward and extends out of the lower side of the bending die 2, thereby pushing the U-shaped tube body 601 that fits in the bending groove downward, thereby completing the separation of the U-shaped tube body 601 from the fixed insertion rod 202 and smoothly dropping the material.

[0048] Preferably, a translation seat 101 is provided to drive the movable insertion rod 1 to move horizontally. After the movable insertion rod 1 is shaped, the current horizontal position can be adjusted so that it can be inserted into the stepped opening 207 and push the push rod 205 to unload the U-shaped tube body 601, thereby further improving the utilization rate of the movable insertion rod 1. The design is simple and reasonable, and no additional structure or driving member is required to drive the push rod 205 separately, thereby saving costs.

[0049] Preferably, a square seat 201 and a pressure rod groove 204 are provided so that the heat exchange tube body 6 on the subsequent feeding platform 5 can be pressed and fixed while the bending work is completed, further ensuring stability during cutting;

[0050] Preferably, the linear drive mechanism includes but is not limited to a lead screw mechanism, a rack and pinion mechanism or a cylinder assembly.

[0051] A lifting seat 102 is provided on the upper side of the translation seat 101. A movable cavity is opened at the lower end of the lifting seat 102. The translation seat 101 moves horizontally in the movable cavity. A top plate 103 is provided on the upper end of the lifting seat 102. The raising block is fixed on the lower side of the top plate 103. A second cylinder 104 is provided on the upper end of the top plate 103. The driving end of the second cylinder 104 is connected to the lifting seat 102.

[0052] Preferably, the lifting seat 102 and the translation seat 101 are driven to move by the second cylinder 104, so that the several movable insertion rods 1 are lowered to perform shaping and pushing operations. When the horizontal position of the movable insertion rods 1 needs to be switched, the translation seat 101 is horizontally displaced in the movable cavity to achieve switching from the shaping position to the pushing position. A linear drive component can be further provided on one side of the lifting seat 102 to drive the horizontal displacement of the translation seat 101.

[0053] Preferably, when a linear drive assembly is installed on one side of the lifting seat 102, it will inevitably cause a lateral load on the lifting seat 102. After long-term use, the lifting seat 102 will be deformed and tilted, thereby affecting the shaping and pushing accuracy of the movable insert rod 1. Therefore, in order to avoid the above situation, trapezoidal wedge blocks 105 and 106 are provided at both ends of the translation seat 101 to realize automatic switching of the horizontal position. Specifically, when the movable insert rod 1 completes the unloading of the U-shaped tube body 601, the lifting seat 102 can be raised and reset until the trapezoidal wedge block 106 contacts the inclined surface of the limit block 107, so that the trapezoidal wedge block 106 slides along its inclined surface, causing the translation seat 101 to move horizontally to the left (such as Figure 3 As shown in the figure, the reduction is completed and the patient returns to the position for plastic surgery, ready for the next plastic surgery.

[0054] The lower end of the top plate 103 is fixedly connected to the bracket plate 4 and a pair of side plates 401. An oblique groove is formed on the side plates 401. Similarly, a second limit block 402 with an inclined surface is provided in the pair of side plates 401. The inclined surface is adapted to the trapezoidal wedge block 105. Both ends of the second limit block 402 are fixedly connected to the limiting rod 403. The limiting rod 403 extends to the oblique groove. One end of the second limit block 402 is fixedly connected to a pair of guide rods 404. A pair of vertical grooves are formed on the bracket plate 4. The guide rod 404 passes through the vertical grooves and slides along them. A sliding piece 405 is slidably fitted on the inner side of the bracket plate 4. The guide rod 404 passes through the sliding piece 405 and slidably fits therewith. A second spring is sleeved on the outer side of the guide rod 404.

[0055] The horizontal position of the second limiting block 402 is lower than that of the first limiting block 107 .

[0056] Preferably, when shaping is required, the lifting seat 102 drives the translation seat 101 and the movable insertion rod 1 to descend, so that the lower end surface of the trapezoidal wedge block 105 contacts the upper end surface of the limit block 2 402, and the limit block 2 402 moves along the inclined groove under the action of the thrust, and the slide 405 slides downward for guidance until the limit block 2 402 is separated from the trapezoidal wedge block 105, and the limit block 2 402 is reset under the action of the spring 2, so as not to affect the shaping of the U-shaped tube body 601 by the movable insertion rod 1. When the shaping is completed, the lifting seat 102 rises and resets. Since the horizontal position of the limit block 2 402 is lower than the limit block 107, so that the trapezoidal wedge block 105 is in contact with the inclined surface of the limit block 2 402 at this time, and slides along its inclined surface, so that the translation seat 101 drives the movable insertion rod 1 to move horizontally to the right, that is, to the pushing position, and then the movable insertion rod 1 can be lowered to complete the pushing of the U-shaped tube body 601. In other words, there is no need for an additional horizontal drive component to drive the translation seat 101. Only through the lifting and displacement of the lifting seat 102, the shaping of the movable insertion rod 1 and the automatic switching of the pushing position can be realized, thereby avoiding the lateral load caused by the installation of an additional linear drive component, thereby affecting the insertion accuracy of the movable insertion rod 1.

[0057] The translation seat 101 is made of magnetic metal, and magnet blocks 108 are provided at both ends of the lifting seat 102 .

[0058] Preferably, in order to further improve the shaping and pushing position accuracy of the movable insertion rod 1 and avoid horizontal deviation, a magnet block 108 is provided. Specifically, when the translation seat 101 is horizontally displaced to the left or right, the translation seat 101 is automatically adsorbed by the magnetic force of the magnet block 108 (the magnetic adsorption can be separated through the above embodiment), thereby fixing the current position of the translation seat 101 and keeping it stationary, thereby improving the shaping and pushing position accuracy.

[0059] The bending assembly includes a blanking cavity 301, a pair of fixed blocks 302 are fixedly connected to both sides of the upper end of the blanking cavity 301, and the bending die 2 is rotatably connected between the pair of fixed blocks 302;

[0060] Step slides are provided at both ends of the inner wall of the unloading cavity 301, and the support seat 3 moves horizontally along the step slides. A first cylinder 8 is provided at the outer end of the unloading cavity 301, and the driving end of the first cylinder 8 is connected to the support seat 3. A unloading bevel is provided in the unloading cavity 301, and a blanking cavity 9 is provided at the lower end of the unloading bevel.

[0061] Preferably, when unloading the U-shaped tube body 601, the first cylinder 8 drives the support seat 3 to move horizontally along the stepped slide rail, thereby moving away from the feeding platform 5. Then, through the above embodiment, the U-shaped tube body 601 can be unloaded and fall onto the unloading inclined mouth, and fall into the unloading cavity 9 for collection.

[0062] A blocking piece 206 is provided in the stepped opening 207 , and the blocking piece 206 is fixedly connected to the push rod 205 . A spring 1 is provided in the stepped opening 207 . In the initial state, one end of the push rod 205 is flush with the surface of the bending groove.

[0063] The minimum inner diameter of the stepped opening 207 is greater than or equal to the diameter of the movable insertion rod 1 .

[0064] Preferably, the baffle 206 is arranged in the stepped opening 207 to limit the push rod 205, and under the action of spring 1, the end face of the push rod 205 in the initial state is adapted to and kept flush with the curvature of the bending groove surface, thereby not affecting the bending surface quality of the U-shaped tube body 601.
