Description

Technical Field

[0001] This application relates to the technical field of bullet ice evaporator processing, and in particular to a necking device for processing the U-shaped tube end of a bullet ice evaporator. Background Technology

[0002] Currently, such as Figure 1 The bullet ice evaporator 10 shown includes a U-shaped tube body 101 and several bullet heads 102 evenly fixed on the U-shaped tube body. The two ends of the U-shaped tube body need to be narrowed. In the prior art, the U-shaped tube is usually inserted into the narrowing machine by a worker.

[0003] However, manual hand-held processing is labor-intensive and prone to producing defective products over long periods of time. At the same time, the production efficiency is also low, making it unsuitable for large-scale production capacity needs. Utility Model Content

[0004] The purpose of this application is to provide a necking device for processing the U-shaped tube end of a bullet ice evaporator, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides a necking device for processing the U-shaped tube end of a bullet ice evaporator, employing the following technical solution: A necking device for processing the U-shaped tube end of a bullet ice evaporator includes a frame and a necking machine mounted on the frame. A servo linear guide slide is mounted on the frame, and the necking machine is mounted on the slide of the servo linear guide slide. A horizontal rail perpendicular to the servo linear guide slide is also fixed on the frame. A feeding mechanism is symmetrically arranged on the horizontal rail. The feeding mechanism includes a drive cylinder, a slider, and a clamping assembly. The slider is slidably connected to the horizontal rail. The drive cylinder is fixed to the horizontal rail and is used to drive the slider to move. The clamping assembly is fixed to the slider and is used to clamp the U-shaped tube.

[0006] The clamping assembly includes a base, a pressing cylinder, a lifting cylinder, a tail limiting block, and a pressure block. The base is fixed on the slider, the tail limiting block is movably disposed at the end of the base, the lifting cylinder is fixed on the base and is used to drive the tail limiting block to rise and fall, the pressing cylinder is disposed on the side of the base, the pressure block is fixed to the piston rod end of the pressing cylinder, and the pressure block is correspondingly disposed on the top of the base. The surfaces of the pressure block and the base are provided with positioning grooves for placing U-shaped tubes, and the surface of the tail limiting block is provided with an arc-shaped groove adapted to the U-shaped tube.

[0007] Preferably, the frame is further provided with a feeding mechanism, which includes a pushing cylinder and a pushing block. The pushing cylinder is fixed on the frame, and the pushing block is fixed to the piston rod end of the pushing cylinder. The frame is provided with a discharge guide groove on one side corresponding to the feeding mechanism.

[0008] By adopting the above technical solution, and by setting up a feeding mechanism, after the necking is completed and the drive cylinder on that side is reset, the pressing cylinder drives the pressure block to rise, and the lifting cylinder pulls the tail limit block down. After that, the pushing cylinder works, and pushes the U-shaped tube into the discharge guide groove through the pushing block to complete the automatic feeding, which further reduces the labor intensity of the workers. The workers only need to perform the feeding action, which can shorten the feeding time.

[0009] Preferably, in order to prevent wear of the clamping assembly and damage to the workpiece, while improving the clamping force and service life, a coating is provided in the positioning groove.

[0010] In summary, this application includes at least one of the following beneficial technical effects: the tube shrinking device for processing the U-shaped tube of the bullet ice evaporator can realize dual-station feeding by symmetrically setting feeding mechanisms on both sides of the shrinking machine. At the same time, each station is also equipped with a discharging mechanism. The operator only needs to perform the feeding action, which has a high degree of automation and low labor intensity. The shrinking machine can realize uninterrupted continuous production and processing, which greatly improves production efficiency. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 2-3 This application will be described in further detail.

[0016] This application discloses a necking device for processing the U-shaped tube end of a bullet ice evaporator, referring to... Figure 2-3The system includes a frame 1 and a shrinking machine 2 mounted on the frame 1. A servo linear guide slide 3 is mounted on the frame 1, and the shrinking machine 2 is mounted on the slide of the servo linear guide slide 3. A horizontal rail 4 perpendicular to the servo linear guide slide 3 is also fixed on the frame 1. A feeding mechanism is symmetrically arranged on the horizontal rail 4. The feeding mechanism includes a drive cylinder 5, a slider 6, and a clamping assembly 7. The slider 6 is slidably connected to the horizontal rail 4. The drive cylinder 5 is fixed on the horizontal rail 4 and is used to drive the slider 6 to move. The clamping assembly 7 is fixed on the slider 6 and is used to clamp the U-shaped tube.

[0017] Reference Figure 3 The clamping assembly 7 includes a base 71, a pressing cylinder 72, a lifting cylinder 73, a tail limiting block 74, and a pressure block 75. The base 71 is fixed on the slider 6. The tail limiting block 74 is movably disposed at the end of the base 71. The lifting cylinder 73 is fixed on the base 71 and is used to drive the tail limiting block 74 to rise and fall. The pressing cylinder 72 is disposed on the side of the base 71. The pressure block 75 is fixed at the end of the piston rod of the pressing cylinder 72 and is disposed on the top of the base 71. The corresponding surfaces of the pressure block 75 and the base 71 are provided with positioning grooves 711 for placing U-shaped tubes. The positioning grooves 711 are provided with a coating, which can prevent wear of the clamping assembly 7 and damage to the workpiece, while improving the clamping force and service life. The surface of the tail limiting block 74 is provided with an arc-shaped groove 741 adapted to the U-shaped tube.

[0018] Reference Figure 2 The frame 1 is also equipped with a feeding mechanism 8, which includes a pushing cylinder 81 and a pushing block 82. The pushing cylinder 81 is fixed on the frame 1, and the pushing block 82 is fixed on the piston rod end of the pushing cylinder 81. The frame 1 is provided with a discharge guide groove 9 on one side corresponding to the feeding mechanism 8.

[0019] By setting up the unloading mechanism 8, after the narrowing is completed and the drive cylinder 5 on that side is reset, the pressing cylinder 72 drives the pressing block 75 to rise, and the lifting cylinder 73 pulls the tail limit block 74 down. After that, the pushing cylinder 81 works, and the pushing block 82 pushes the U-shaped tube into the discharge guide trough 9 to complete the automatic unloading, which further reduces the labor intensity of the workers. The workers only need to perform the loading action, which can shorten the loading time.

[0020] The implementation principle of the necking device for processing the U-shaped tube end of a bullet ice evaporator according to an embodiment of this application is as follows: By symmetrically arranging feeding mechanisms on both sides of the shrinking machine 2, dual-station feeding can be achieved, and the shrinking machine 2 can continuously perform shrinking processing to improve production efficiency. During the production process, the operator only needs to place the U-shaped tube into the positioning groove 711 and make the end of the U-shaped tube abut against the inner wall of the arc groove 741. Then, the pressing cylinder 72 drives the pressing block 75 to press the U-shaped tube tightly onto the base 71. The driving cylinder 5 drives the slider 6 to move to the side of the shrinking machine 2, and the servo linear guide slide 3 drives the shrinking machine 2 to move closer to one side of the U-shaped tube and perform shrinking work. After the shrinking is completed, the feeding mechanism on the other side repeats the above actions and cooperates with the unloading mechanism 8. One operator can achieve feeding at two stations, thereby realizing uninterrupted continuous production processing and greatly improving production efficiency.

[0021] 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.
