Description

Technical Field

[0001] The invention belongs to the technical field of pipe processing, and in particular relates to a manufacturing and processing device for a heating, ventilation and air conditioning component. Background Art

[0002] The air conditioner evaporator is a type of evaporator. The function of the air conditioner evaporator is to use the liquid low-temperature refrigerant to evaporate easily under low pressure, turn into steam and absorb the heat of the cooled medium, thereby achieving the purpose of refrigeration.

[0003] The pipe fittings in the evaporator are important components in the evaporator. Failure to meet the processing requirements will have very serious consequences. The quality of the pipe expansion process directly affects whether the parts connected to the evaporator pipe fittings are qualified, and also affects whether the overall air-conditioning equipment can operate well.

[0004] Flaring is to enlarge the mouth of a cylindrical stretched part or a circular tube. The prior art generally uses stamping to achieve flaring, but there are the following problems during the stamping process: 1. Since the pipe fitting is a hollow structure, the prior art generally does not fix the pipe mouth when stamping the pipe fitting, so it is inevitable that the flared mouth will crack during stamping or a certain part of the pipe fitting will bend during stamping; 2. The evaporator pipe fitting is relatively soft in texture, and it is generally impossible to ensure that the force on the inner wall of the pipe fitting is uniform at the moment of stamping, which makes the pipe fitting mouth unable to reach the qualified stamping parameters during flaring and even causes the pipe mouth to crack.

Detailed implementation manners

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] It should be noted that the terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0033] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0034] Refer to Figure 1 , Figure 2 and Figure 4 It can be known that a manufacturing and processing device for a heating, ventilation and air conditioning (HVAC) component includes a workbench 1. A displacement device 2 is arranged on the horizontal section below the workbench 1. A linkage device 3 is arranged above the displacement device 2. A driving device 4 is arranged on the front side of the horizontal section below the workbench 1. A limiting device 5 is arranged between the upper and lower horizontal sections of the workbench 1. Clamping devices 6 are arranged symmetrically about the front and rear centers of the horizontal section below the workbench 1. A flaring device 7 that cooperates with the clamping device 6 is arranged at one end of the clamping device 6 away from the workbench 1;

[0035] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 7It can be known that the displacement device 2 includes a displacement groove 21, a mounting groove 22, a sliding block 23, a C-shaped seat 24, a fixing plate 25, a support plate 26, a T-shaped plate 27 and a relief groove 28. A horizontally penetrating displacement groove 21 is opened at the middle position of the horizontal section below the workbench 1. Mounting grooves 22 are opened on the front and rear sides of the displacement groove 21. Two sliding blocks 23 are slidably mounted in the displacement groove 21 from left to right, and the two sliding blocks 23 are fixedly connected by a fixing frame. The upper end of the sliding block 23 is provided with a C-shaped seat 24. Fixing plates 25 are symmetrically mounted on the front and rear vertical sections of the C-shaped seat 24. A support plate 26 is commonly mounted on the upper ends of the C-shaped seat 24. T-shaped plates 27 are symmetrically mounted before and after between the vertical sections on the left and right sides of the workbench 1. A relief groove 28 is opened on the upper end surface of the vertical section of the T-shaped plate 27.

[0036] After the operator places the pipe fitting to be processed at the specified position on the upper end surface of the T-shaped plate 27, and both the inlet end and the outlet end of the pipe fitting to be processed are inside the relief groove 28, drive the sliding block 23 to slide rightward in the displacement groove 21. Specifically, an electric slider can be used to drive the sliding block 23 to displace. Under the action of the sliding block 23, the C-shaped seat 24 drives the fixing plate 25 thereon to slide rightward inside the mounting groove 22, and at the same time drives the support plate 26 at its upper end to move rightward by a certain distance synchronously.

[0037] Refer to Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Fig. 9 It can be known that the linkage device 3 includes a guide rod 31, a gear 32, a first toothed belt pulley 33, a screw rod 34, a connecting rod 35, a second toothed belt pulley 36 and an arc-shaped block 37. A guide rod 31 is commonly mounted between the front vertical sections on the left and right sides of the support plate 26. A gear 32 and a first toothed belt pulley 33 are mounted on both the left and right sides of the guide rod 31, and the gear 32 is located on the left side of the first toothed belt pulley 33 at the same end. A screw rod 34 and a connecting rod 35 are symmetrically mounted before and after between the vertical sections at the middle positions on the left and right sides of the support plate 26, and the connecting rod 35 is located behind the screw rod 34. Second toothed belt pulleys 36 are symmetrically mounted at both ends of the screw rod 34, and the first toothed belt pulley 33 and the second toothed belt pulley 36 are driven by a toothed belt. Arc-shaped blocks 37 are symmetrically mounted on the front left and right sides of the lower end surface of the horizontal section of the support plate 26.

[0038] During the movement of the support plate 26, the arc-shaped block 37 gradually releases the pressing on the driving device 4. When the driving device 4 resets upward, it drives the gear 32 to rotate, and then drives the screw rod 34 to rotate synchronously through the transmission of the first toothed belt pulley 33, the second toothed belt pulley 36 and the toothed belt.

[0039] Refer to Figure 1 、 Figure 2 、 Figure 5 and Fig. 9It can be seen that the driving device 4 includes a support 41, a telescopic plate 42, a rack 43, a buckle 44, a positioning plate 45 and a slot 46. The support 41 is installed on both sides of the left and right sides of the front end of the upper end of the horizontal section below the workbench 1, and the telescopic plate 42 is slidably installed in the support 41. The rack 43 is installed on the upper end surface of the telescopic plate 42, and the buckle 44 is installed on the upper end of the rack 43. The positioning plate 45 is symmetrically connected to the outer wall of the vertical section of the front T-shaped plate 27 close to the gear 32, and the position of the positioning plate 45 in the vertical direction can be adjusted. The lower end surface of the positioning plate 45 is provided with a slot 46 that matches the buckle 44.

[0040] The arc block 37 first contacts the upper end surface of the telescopic plate 42 under the action of the support plate 26. The telescopic plate 42 under pressure drives the rack 43 thereon to no longer mesh with the gear 32. When the arc block 37 is separated from the telescopic plate 42, the telescopic plate 42 under pressure recovers to its initial state upward under the action of its own elastic force. The telescopic plate 42 moving upward drives the rack 43 thereon to move upward. At this time, the rack 43 is just in the area meshing with the gear 32. Therefore, the rack 43 drives the gear 32 to rotate while following the telescopic plate 42 moving upward, and After the rack 43 moves upward to the initial state, the buckle 44 in the slot 46, which was originally disengaged due to the compression of the telescopic plate 42 by the arc block 37, is again engaged with the slot 46 in the positioning plate 45 after the operator adjusts the position, so that the rack 43 only drives the gear 32 meshing with it to rotate in one direction during the upward movement, avoiding the gear 32 from driving the screw 34 to rotate forward and reverse through the first toothed belt pulley 33 and the second toothed belt pulley 36 due to the elasticity of the telescopic plate 42, thereby affecting the limiting effect of the subsequent limiting device 5.

[0041] Reference Figure 4 , Figure 8 and Fig.12 It can be seen that the limiting device 5 includes a key block 51, a clamping plate 52, a mounting seat 53, an extrusion claw 54, a flexible pad 55 and a groove 56. The key block 51 is evenly installed on the outer wall of the screw 34 from left to right, and the key block 51 and the connecting rod 35 are installed by sliding fit. The upper end of the key block 51 is installed with a clamping plate 52, and the mounting seats 53 are evenly installed on the upper and lower horizontal sections of the clamping plate 52 from front to back. Extrusion claws 54 are evenly installed from front to back between the mounting seats 53 through a rotating shaft. A flexible pad 55 is installed at one end of the extrusion claw 54. The inner wall of the flexible pad 55 is a serrated structure. A groove 56 matching the extrusion claw 54 is opened in the clamping plate 52; thread grooves 341 are equidistantly opened on the screw 34 from left to right, and the thread rotation directions of adjacent thread grooves 341 are opposite.

[0042] In the initial state of the pipe to be processed, the operator places it between adjacent clamping plates 52. Therefore, when the displacement device 2 drives the support plate 26 to move to the right end, the key block 51 drives the clamping plate 52 thereon to move to the right. At the same time, the screw rod 34 rotates to drive the adjacent key blocks 51 thereon to move toward each other, thereby making the adjacent clamping plates 52 approach to a certain section of the outer wall of the pipe to be processed between the adjacent clamping plates 52. In the process of the adjacent clamping plates 52 approaching, the vertical section of the squeezing claw 54 is first squeezed by the outer wall of a certain section of the pipe to be processed, and then the squeezing claw 54 is rotated. The horizontal section of the rotated squeezing claw 54 squeezes the outer wall of the section of the pipe to be processed after rotating a certain angle, and the flexible pad 55 designed with a zigzag structure first squeezes the outer wall of the section of the pipe to be processed, so as to avoid the squeezing claw 54 from contacting with the direct force-bearing part of the pipe to be processed, so as to avoid the outer wall of the pipe to be processed from being recessed when the pipe to be processed is limited, thereby affecting the quality of the pipe.

[0043] Reference Figure 1 , Figure 3 , Figure 5 , Fig.10 and Fig.11 It can be known that the clamping device 6 includes a slide groove 61, a telescopic base 62, a cross plate 63, an L-shaped plate 64, a No. 1 round tube 65, a fixed seat 66, an extrusion piece 67 and an arc pad 68. The slide groove 61 connected to the installation groove 22 is symmetrically provided in the front and rear center of the horizontal section below the workbench 1, and the telescopic base 62 is slidably installed between the slide groove 61 and the installation groove 22. The end of the upper end surface of the telescopic base 62 away from the workbench 1 is installed with a cross plate 63, and the upper end surface of the horizontal section below the workbench 1 is installed with an L-shaped plate 64 corresponding to the cross plate 63. A No. 1 round tube 65 is fixedly installed on the upper end of the cross plate 63, and the No. 1 round tube 65 can slide in the L-shaped plate 64. The outer wall of the end of the No. 1 round tube 65 close to the gear 32 is evenly installed with a fixed seat 66 along the circumferential direction, and an elastic extrusion piece 67 is slidably installed between the fixed seat 66 and the outer wall of the No. 1 round tube 65. The end surface of the extrusion piece 67 close to the gear 32 is symmetrically installed with an arc pad 68.

[0044] First, the No. 1 round tube 65 in the cross plate 63 is on the same horizontal line as the axis of the pipe to be processed. When the displacement device 2 moves, one end of the fixed plate 25 pushes the telescopic base 62 to move, so as to prevent the adjacent clamping plate 52 from driving the pipe to be processed to move to the right inside the make way groove 28 as a whole and being blocked by the No. 1 round tube 65. That is, after being compressed, the telescopic base 62 drives the cross plate 63 thereon and the No. 1 round tube 65 on the cross plate 63 to move as a whole away from the workbench 1 to make way for the right movement of the pipe to be processed. When the fixed plate 25 is separated from the telescopic base 62, the telescopic base 62 drives the cross plate 63 and the No. 1 round tube 65 on the cross plate 63 under the action of its own elastic force. The No. 1 round tube 65 returns to its initial position, at which point the end of the No. 1 round tube 65 close to the pipe to be processed is just aligned with the center of the inlet or outlet end of the pipe to be processed, and the inlet or outlet end of the pipe to be processed just extends into the No. 1 round tube 65 by a specified distance. During the resetting of the No. 1 round tube 65, the arc pad 68 on the extrusion piece 67 first contacts the outer wall of the pipe to be processed, and then the arc design of the arc pad 68 reduces the friction when it contacts the pipe to be processed, so that the inlet or outlet end of the pipe to be processed can smoothly enter the interior of the No. 1 round tube 65, and then the radial elastic force of the arc pad 68 is used to extrude and limit the outer wall of the pipe to be processed.

[0045] Reference Figure 1 , Figure 3 , Fig.10 and Fig.13 It can be seen that the expanding device 7 includes a U-shaped plate 71, a No. 2 round tube 72, a No. 1 clamping block 73, a No. 2 clamping block 74, a guide seat 75, a rotating column 76, a round table 77 and a pressure sensor 78. The U-shaped plate 71 is symmetrically installed at the front and rear ends of the horizontal section below the workbench 1. The No. 2 round tube 72 is slidably installed on the upper end of the vertical section of the U-shaped plate 71. The No. 1 clamping block 73 that slides with the horizontal section below the U-shaped plate 71 is fixedly installed on the outer wall of the No. 2 round tube 72 near the horizontal section below the U-shaped plate 71. A second clamping block 74 is fixedly installed on the outer wall of the circular tube 72 away from the horizontal section below the U-shaped plate 71, and a guide seat 75 is installed on the upper end of the second clamping block 74, and the guide seat 75 is slidably installed with the horizontal section above the U-shaped plate 71. A rotating column 76 is rotatably installed in the second circular tube 72, and different types of round tables 77 are evenly installed from front to back at one end of the rotating column 76 close to the workbench 1, and pressure sensors 78 are installed on the small end and the large end of the round table 77; the inner wall of the extrusion piece 67 is a serrated structure.

[0046] When the pipe to be processed is squeezed and limited by the arc pad 68, the guide seat 75 is pushed to move in the direction close to the workbench 1. Specifically, an electric slider can be used to drive the guide seat 75 to move. During the movement, the guide seat 75 drives the second clamping block 74 fixedly connected to its lower end to move synchronously, and then the second round tube 72 drives the rotating column 76 therein and the round table 77 on the rotating column 76 to move toward the workbench 1. The guide seat 75 is slidably installed with the horizontal section above the U-shaped plate 71, and the first clamping block 73 is slidably installed with the horizontal section below the U-shaped plate 71, so as to improve the stability and uniformity of the expanding device 7 when expanding the pipe to be processed, avoid the expansion cracking of the pipe to be processed during the expansion process, and improve the qualified rate of the expansion of the pipe to be processed. When the movable No. 2 circular tube 72 and the rotating column 76 therein move slowly, the rotating column 76 rotates at the same time, and the extrusion piece 67 with a serrated structure design in the clamping device 6 applies a force in the opposite direction of the expanding force to the outer wall of the pipe to be processed after the expansion reaches a certain degree, so that the extrusion piece 67 and the round table 77 form an inner and outer mold, which improves the stability of the expansion and the uniformity of the force; and when expanding different types of pipes to be processed, it can be achieved by using round tables 77 of different diameters, that is, when the pressure sensor 78 at the small end of the round table 77 contacts the pipe to be processed for the first time and sends a signal, the electric slider and the external motor start at the same time, and after the pressure sensor 78 at the large end of the round table 77 contacts the pipe to be processed again and sends an electrical signal, the electric slider and the external motor stop working at the same time.

[0047] The present invention provides a HVAC component manufacturing and processing device with the following working principle: Step 1: The operator places the pipe to be processed at a suitable position, and the displacement device 2 moves to the right, so that the rack 43 in the driving device 4 drives the gear 32 in the linkage device 3 to rotate, and then the linkage device 3 transmits the rotation of the gear 32 to the adjacent clamping plates 52 on the screw 34 via the first toothed belt wheel 33 and the second toothed belt wheel 36. When the adjacent clamping plates 52 approach each other, the outer wall of the pipe to be processed is clamped and fixed by the extrusion claws 54 thereon and the serrated flexible pads 55 in the extrusion claws 54;

[0048] Step 2: During the movement of the displacement device 2 to the right, the fixing plate 25 is checked to see whether it contacts the telescopic base 62, so that the clamping device 6 as a whole makes way for the inlet or outlet of the pipe to be processed and resets. After the reset, the first round tube 65 in the clamping device 6 and the extrusion piece 67 and the arc pad 68 inside the clamping device 6 clamp and fix the inlet or outlet of the pipe to be processed.

[0049] Step 3: After the position of the pipe to be processed is completely limited by the clamping device 6 and the limiting device 5, the guide seat 75 is driven by the electric slider to drive the No. 2 round tube 72 at the lower end of the No. 2 clamping block 74 and the rotating column 76 inside it to move stably toward the direction of the workbench 1 under the joint action of the No. 1 clamping block 73. During the movement, the rotating column 76 is rotated at the same time by an external motor, and the pressure sensor 78 is used to determine whether the expansion is completed through the signals transmitted by the first and second contact pressure sensor 78.

[0050] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0051] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
