Description

Technical Field

[0001] This utility model relates to the field of washing machine evaporator manufacturing technology, specifically an adjustable washing machine evaporator bending and forming device. Background Technology

[0002] The bending and forming of the washing machine evaporator is a critical step in the production process, and its quality directly affects the heat exchange efficiency and reliability of the evaporator. The metal pipes (such as copper or aluminum pipes) in the evaporator need to be bent. For example, the coil section of the evaporator usually requires multiple bends to form a spiral or serpentine path to increase the heat exchange area, while the inlet and outlet pipes of the evaporator need to be bent to adapt to the internal space layout of the washing machine.

[0003] Chinese utility model patent CN219130426U discloses a U-shaped tube bending device for evaporators. This device can perform corresponding bending operations on the tube by using the cooperation between the bending disc rotating frame and the bending top plate in the bending mechanism. The cooperation between the movable bracket and the cutting blade in the cutting mechanism can cut the corresponding position of the bent tube, avoiding the need to remove it and process it with cutting equipment. It can also adapt to different cutting lengths by moving the cutting blade. However, the device only relies on the mechanical clamping of the bending top plate and the bending disc to fix the tube. Moreover, it cannot clamp and transport the tube during the bending process, which requires manual control and poses certain safety hazards. Furthermore, because the tube is always clamped, the bent tube cannot be freely removed.

[0004] Therefore, we propose an adjustable washing machine evaporator bending and forming device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable washing machine evaporator bending and forming device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable washing machine evaporator bending and forming device includes an operating table, a control panel with a PLC controller, and two support frames. Each support frame has two relatively distributed clamps, and a feeding component is slidably arranged between the side walls of the two support frames. A pipe is clamped between the clamps on the two support frames and is intermittently conveyed by the feeding component.

[0008] One of the support frames is also equipped with a fixed frame three on one side of the operating table. The fixed frame three is equipped with a cutting component, and a bending component is provided on one side of the fixed frame three. A bending column that moves along the width direction of the operating table is provided on one side of the bending component.

[0009] According to the above technical solution, a fixed seat is fixedly installed on the operating table. A fixed groove is opened on the fixed seat along its length direction. A screw is rotatably installed in the fixed groove. A slide is slidably installed between the inner walls of the fixed groove.

The auxiliary wheel is mounted on one end of the rotating seat via a connecting shaft. The gear is rotatably mounted on the top surface of the fixed frame via a synchronous shaft. The bending plate is mounted on the synchronous shaft via a connector and has an arc-shaped structure.

[0011] According to the above technical solution, a fixed frame two is fixedly installed on the operating table, an electric cylinder is installed on the fixed frame two, a rack is connected to the output end of the electric cylinder, a dovetail-shaped guide bar is connected to the bottom wall of the rack, the guide bar slides through the inner wall of the top surface of the fixed frame one, and the rack and gear are meshed with each other.

[0012] According to the above technical solution, the fixed frame three is provided with a through hole, and a screw two is rotatably arranged between the top side walls of the fixed frame three. A movable seat one is slidably arranged on the fixed frame three along its surface. The screw two passes through the movable seat one and is engaged with it through threaded transmission. A laser head is installed on the bottom wall of the movable seat one, and a controller for driving the laser head is installed on one side wall of the movable seat one.

[0013] According to the above technical solution, the top of the support frame is provided with a fixing groove 2, and a screw 3 is rotatably installed in the fixing groove 2. A slider is installed on the bottom wall of the clamp, and the slider slides between the inner walls of the fixing groove 2.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] An adjustable washing machine evaporator bending and forming device includes an operating table 1, on which a control panel 11 with a PLC controller is fixedly installed. Two support frames 6 are fixedly installed on the operating table 1. Each of the two support frames 6 is provided with two relatively distributed clamps 61. A feeding component is slidably arranged between the side walls of the two support frames 6. A pipe is clamped between the clamps 61 on the two support frames 6. The pipe is clamped on the feeding component for intermittent feeding.

[0027] One of the support frames 6 is also equipped with a fixing frame 3 5 on one side of the operating table 1. The fixing frame 3 5 is equipped with a cutting component, and a bending component is provided on one side of the fixing frame 3 5.

[0028] A bending column 211 that moves along the width of the operating table 1 is provided on one side of the bending assembly. A fixed seat 2 is fixedly installed on the operating table 1. A fixed groove is provided on the fixed seat 2 along its length. A screw is rotatably installed in the fixed groove. A rotary motor is connected to one end of the screw. The rotary motor is installed on the side wall of the fixed seat 2. A slide 21 is slidably installed between the inner walls of the fixed groove. The screw passes through the slide 21 and is engaged with it through threaded transmission. The bending column 211 is installed on the top surface of the slide 21 by threaded connection.

[0029] It should be further explained that the pipeline is conveyed by being clamped between the clamps 61 and held by the feeding assembly. The pipeline passes through the fixed frame 3 5 and is located below the cutting assembly. After passing through the bending assembly, the pipeline is bent by the bending column 211.

[0030] According to the above technical solution, the bending assembly includes a fixed frame 3, a gear 31, a bending plate 32, an auxiliary wheel 33, and a rotating seat 34. The fixed frame 3 has an "L" shaped structure and its bottom end is fixed on the operating table 1. The rotating seat 34 is rotatably mounted on the top surface of the operating table 1 via a shaft connection. A drive motor (not shown in the figure) is installed between the inner walls of the operating table 1. The drive motor drives the rotating seat 34 to rotate. An auxiliary wheel 33 is provided on one end of the rotating seat 34 via a connecting shaft 331, and a rotating shaft is connected to the other end of the rotating seat 34. The top end of the rotating shaft rotates on the bottom wall of the fixed frame 3. The gear 31 is rotatably mounted on the top surface of the fixed frame 3 via a synchronous shaft 311. The bending plate 32 is mounted on the synchronous shaft 311 via a connector, and the bending plate 32 has an arc-shaped structure.

[0031] The connector consists of a ring and two connecting rods. The ring is fixed on the synchronous shaft 311, one end of the connecting rod is fixed on the ring, and the other end of the connecting rod is connected to the bending plate 32 by attraction. The bending plate 32 has a connecting groove, and a magnet is embedded at the bottom of the connecting groove. A magnet is also embedded at the end of the connecting rod.

[0032] A fixed frame 4 is fixedly installed on the operating table 1. An electric cylinder 41 is installed on the fixed frame 4. A rack 42 is connected to the output end of the electric cylinder 41. A dovetail-shaped guide bar is connected to the bottom wall of the rack 42. The guide bar slides through the inner wall of the top surface of the fixed frame 3. The rack 42 and the gear 31 are meshed with each other.

[0033] It should be further explained that the bending plate 32 and the gear 31 are connected together by a connector so that they can rotate and adjust synchronously. The rack 42 is moved by the electric cylinder 41, so that the rack 42 controls the rotation of the gear 31 when it moves. The gear 31 rotates 180 degrees each time, thereby switching the relative state of the bending plate 32 and the auxiliary wheel 33. When the outer arc surface of the bending plate 32 is opposite to the auxiliary wheel 33, the pipe can be tightly clamped between the bending plate 32 and the auxiliary wheel 33. When the inner arc surface of the bending plate 32 is opposite to the auxiliary wheel 33, the pipe is in a relaxed state, and the bent pipe can be easily removed.

[0034] A through hole is provided on the fixed frame 3 5. A screw 2 is rotatably installed between the top side walls of the fixed frame 3 5. A rotary motor 2 is connected to one end of the screw 2. The rotary motor 2 is installed on the side wall of the fixed frame 3 5. A movable seat 1 51 is slidably installed on the fixed frame 3 5 along its surface. The screw 2 passes through the movable seat 1 51 and is engaged with it through threaded transmission. A laser head 512 is installed on the bottom wall of the movable seat 1 51. A sub-controller 511 that drives the laser head 512 is installed on one side wall of the movable seat 1 51 (the sub-controller 511 is connected to the PLC controller through an electrical signal).

[0035] It should be further explained that by starting the rotary motor 2, it drives the screw 2 to rotate, thereby controlling the displacement of the moving seat 51 to achieve the direction of laser cutting. During cutting, the sub-controller 511 is started and the laser head 512 emits laser to cut the pipe below.

[0036] The top of the support frame 6 is provided with a fixing groove 2, and a screw 3 is rotatably installed in the fixing groove 2. A rotary motor 3 is installed on the side wall of the fixing groove 2. The rotary motor 3 is connected to and drives the screw 3. A slider is installed on the bottom wall of the clamp 61. The slider slides between the inner walls of the fixing groove 2, and the screw 3 slides through and engages with it through threaded transmission. A crossbeam 62 is installed between the side walls of the two support frames 6 on the same side by screws. A "U"-shaped limiting frame 621 is fixed to the crossbeam 62 on both sides by bolts. A screw 4 is rotatably installed between the opposite side walls of the two support frames 6. A rotary motor 4 (not shown in the figure) is installed on the side wall of one of the support frames 6. The rotary motor 4 is connected to and drives the screw 4.

[0037] The feeding assembly includes a movable seat 7, a top cover 71, an elastic plate 711, and side clamps 712. The bottom end of the movable seat 7 slides between the side walls of the two crossbeams 62, and the screw 4 passes through the movable seat and is threadedly driven to it. Contact sensors are embedded on both side walls of the movable seat 7 (the contact sensors are connected to the PLC controller via electrical signals). The top cover 71 is fixedly connected to the top of the movable seat 7, and the bottom end of the top cover 71 has an arc surface. The elastic plate 711 is elastically set at the top of the arc surface through a shaft connection. There are two symmetrically arranged side clamps 712, and the side clamps 712 are movable through an electric push rod, which is installed on the side wall of the top cover 71.

[0038] It should be further explained that when clamping the pipeline, the electric push rod is activated, causing the side clamping plate 712 to move closer to and contact the pipeline, thereby clamping and fixing the pipeline. The pipeline is synchronously conveyed in the forward direction as the side clamping plate 712 clamps it. At the same time, the moving seat 2 7 can only reciprocate between the two limit frames 621. When the contact sensor is triggered, the rotary motor 4 changes the conveying direction, thereby changing the movement direction of the moving seat 2 7. When the moving seat 2 7 moves away from the fixed frame 3 5, the electric push rod drives the side clamping plate 712 to reset and leave the pipeline. Conversely, when the moving seat 2 7 moves closer to the fixed frame 3 5, the electric push rod drives the side clamping plate 712 to move closer to and clamp the pipeline.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
