[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. The present invention will be further described below in conjunction with the embodiments.

[0021] Please refer to Figures 1 to 10, in an embodiment of the present application, a feeding device for a pipe orifice shrinking machine in the processing of radiator pipe fittings includes a base 1 and a shrinking machine 7 installed on the base 1. An adjusting mechanism is provided on the side of the base 1 away from the shrinking machine 7. Two storage mechanisms are symmetrically arranged on the base 1 and the adjusting mechanism. A storage cavity is formed between the two storage mechanisms, and the adjusting mechanism is used to adjust the length of the storage cavity to meet the necking processing of radiator pipe fittings of different lengths; A blanking port 5 is opened on the side of the base 1 inside the storage cavity, and a feeding assembly is arranged on both sides of the blanking port 5 on the base 1. The feeding assembly includes a driving mechanism and a feeding mechanism. The number of feeding mechanisms is two, and the two feeding mechanisms are symmetrically arranged on both sides of the blanking port 5; The driving mechanism is used to synchronously move the two feeding mechanisms closer and move the radiator pipe fitting to the axis of the shrinking machine 7 for necking processing.

[0022] Furthermore, one end of a blanking plate 4 is also connected to the side of the blanking port 5 close to the storage mechanism, and the other end of the blanking plate 4 slopes downward.

[0023] This embodiment is implemented as follows: In use, first, the base 1 is used in cooperation with the adjusting mechanism to form a bearing main body for storing radiator pipe fittings. Here, it is a storage area, aiming to perform a large amount of feeding at one time, concentrating the pipe fittings to be processed into the storage cavity. The two storage mechanisms support and store the radiator pipe fittings, and during processing, the radiator pipe fittings are sequentially fed to the axis of the shrinking machine 7 for necking processing. In this way, the operation of manually feeding single pipes is eliminated, and the processing efficiency is greatly improved.

[0024] The existing problem is that for radiator pipe fittings or other pipe fittings, their lengths are different. Therefore, the adjusting mechanism cooperates with the base 1 for adjustment. Storage mechanisms are provided on both the adjusting mechanism and the base 1. The storage cavity between the two storage mechanisms is used to store the radiator pipe fittings to be processed. At the same time, the adjusting mechanism can drive the storage above it to move, so as to adjust the length of the storage cavity, meet the placement and processing of radiator pipe fittings of different lengths, and thus improve the applicability.

[0025] The feeding assembly cooperates with the storage mechanism. After a single pipe fitting exists in the storage part 22, it can automatically feed the pipe fitting to the axis of the shrinking machine 7 to achieve automatic feeding. After processing is completed, when the feeding mechanism retracts, the processed pipe fitting will automatically fall into the blanking port 5, so as to achieve automatic loading and unloading, and greatly improve the processing efficiency of the shrinking machine 7.

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、Figure 5 , Figure 6 and Figure 7 , as a preferred embodiment of the present application, a single storage mechanism includes a storage plate 8, a first guide bar 10 and a second guide bar 11 installed on the side of the storage plate 8. A vertical plate 9 is further provided at the end of the first guide bar 10, and the vertical plate 9 is perpendicular to the storage plate 8; A bearing plate 20 is further provided below the second guide bar 11 on the side of the storage plate 8. The bearing plate 20 is perpendicular to the vertical plate 9, and a stop block 21 is provided between the lower end of the bearing plate 20 and the second guide bar 11. A storage part 22 is formed among the stop block 21, the vertical plate 9 and the end of the bearing plate 20, and a material blocking mechanism is installed at the end of the bearing plate 20.

[0027] Furthermore, the material blocking mechanism includes an installation groove 23 opened at the end of the bearing plate 20, a front baffle 24 rotatably installed inside the installation groove 23, and a return spring 28 installed in the installation groove 23. The end of the return spring 28 is connected to the side of the front baffle 24.

[0028] This embodiment is implemented as follows: A single storage mechanism is composed of a storage plate 8 and the first guide bar 10 and the second guide bar 11 provided on the side. The first guide bar 10 is vertically arranged, and the second guide bar 11 is obliquely arranged, so that the ends of the first guide bar 10 and the second guide bar approach each other to form a blanking port 5, and finally enter the storage part 22 through the blanking port 5. The function of the blanking port 5 is to allow the pipe fittings to pass through one by one, so that after multiple pieces of feeding, automatic single-piece blanking can be realized; The function of the bearing plate 20 is to support and temporarily store the pipe fittings passing through the blanking port 5, and is blocked by the material blocking mechanism to prevent falling. Specifically, the front baffle 24 is pulled by the return spring 28 to keep the front baffle 24 in a pulled-back state; The pipe materials appearing in the storage part 22 will be sent by the feeding assembly to the axis of the pipe shrinking machine 7 for necking processing. During the feeding process, the pipe fittings will naturally contact the front baffle 24, stretching the return spring 28. At the same time, the front baffle 24 falls down. After the pipe fittings are sent into the storage part 22, the return spring 28 contracts, pulling the front baffle 24 back and continuing to block, and so on.

[0029] Please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figures 8 to 9 , as a preferred embodiment of the present application, the adjusting mechanism includes a moving seat 2, a connecting block 30 installed below the moving seat 2, and an adjusting cylinder 29 installed below the base 1. One end of an adjusting rod 31 is also connected to the side of the connecting block 30 close to the adjusting cylinder 29. An adjusting cavity 32 is provided inside the adjusting cylinder 29, and the other end of the adjusting rod 31 is inserted into the adjusting cavity 32; On both sides of the interior of the adjustment cavity 32, limiting grooves 33 are symmetrically provided. A number of concave circular grooves 34 are evenly provided in the limiting grooves 33. On both sides of the other end of the adjustment rod 31, limiting blocks 35 are provided. A spring cavity 36 is provided in a single limiting block 35. A limiting seat 38 is slidably connected inside the spring cavity 36. A pressing spring 37 is installed between the limiting seat 38 and the inner bottom of the spring cavity 36. A limiting bead 39 is embedded at one end of the limiting seat 38 away from the pressing spring 37. The limiting bead 39 abuts against the concave circular groove 34.

[0030] Furthermore, a number of support feet 3 are installed below both the base 1 and the moving seat 2. Universal wheels are provided inside the ends of the support feet 3 below the moving seat 2. A baffle 19 is also installed above the moving seat 2, and the baffle 19 is coaxially arranged with the pipe shrinking machine 7.

[0031] This embodiment is implemented as follows: As mentioned before, the problem at the current stage is that for radiator pipe fittings or other pipe fittings, their lengths are all different. Therefore, the adjustment mechanism is used in cooperation with the base 1 for adjustment. Specifically, the adjustment mechanism is composed of a connecting block 30 below the moving seat 2, an adjustment rod 31, and an adjustment cylinder 29 installed below the base 1. Its adjustment is mainly to adjust the position of the moving seat 2 and the storage mechanism provided above the moving seat 2. Therefore, by inserting the adjustment rod 31 into the interior of the adjustment cylinder 29, when adjusting the position of the moving seat 2, by pulling the moving seat 2, the support feet 3 below the moving seat 2 cooperate with the universal wheels to move, so that the adjustment rod 31 displaces inside the adjustment cylinder 29, thus controlling the interval between the moving seat 2 and the base 1.

[0032] However, simply adjusting the position of the moving seat 2 without fixing the position of the moving seat 2 will cause the overall structure to be unstable and unable to stably carry the radiator pipe fittings. Therefore, limiting grooves 33 are symmetrically provided on both sides of the interior of the adjustment cavity 32. A number of concave circular grooves 34 are evenly provided in the limiting grooves 33. Limiting blocks 35 are also provided on both sides of the other end of the adjustment rod 31 inside the adjustment cylinder 29. And a spring cavity 36 is provided in a single limiting block 35. A limiting seat 38 is slidably connected inside the spring cavity 36. A pressing spring 37 is installed between the limiting seat 38 and the inner bottom of the spring cavity 36. A limiting bead 39 is embedded at one end of the limiting seat 38 away from the pressing spring 37. The limiting bead 39 abuts against the concave circular groove 34. When the adjustment rod 31 displaces, the pressing spring 37 will drive the limiting seat 38 to displace. At the same time, the limiting bead 39 moves in a number of concave circular grooves 34. During this process, the pressing spring 37 will contract reciprocally, thus realizing auxiliary fixation.

[0033] During the actual pipe shrinking process, the position of the moving seat 2 can also be assisted in being fixed. The overall purpose of the adjustment mechanism is to facilitate adjusting the interval between the moving seat 2 and the base 1.

[0034] Please refer toFigure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 10 , as a preferred embodiment of the present application, the driving mechanism includes a mounting seat 17 installed on the base 1, a driving cavity inside the mounting seat 17, and a motor 6 arranged on the side of the mounting seat 17. The power output shaft of the motor 6 extends into the driving cavity and is connected to one end of a first screw rod 25. The other end of the first screw rod 25 is connected to one end of a second screw rod 26. The thread directions on the outer sides of the first screw rod 25 and the second screw rod 26 are opposite, and screw sleeves 27 are threadedly connected to the outer sides of both the first screw rod 25 and the second screw rod 26. One end of a connecting rod 12 is connected to the outer side of the screw sleeve 27; The connecting rod 12 is slidably connected inside the driving cavity, and the ends of the two connecting rods 12 are respectively connected to the outside of their respective adjacent feeding mechanisms.

[0035] Furthermore, a single feeding mechanism includes a slide rail 14 arranged on the side of the blanking port 5, a slider 13 slidably connected to the slide rail 14, and a feeding plate 15 connected above the slider 13. A fitting portion 16 is arranged on one side of the feeding plate 15 close to the blanking port 5, and the end of the connecting rod 12 is connected to the side of the slider 13.

[0036] Furthermore, a moving port 18 is further arranged at the lower end of the storage plate 8 close to the pipe shrinking machine 7, and the connecting rod 12 close to the storage plate 8 is slidably installed in the moving port 18.

[0037] It should be noted that the main function of the driving mechanism is to move the two feeding mechanisms closer to each other. During the process of moving closer, the feeding mechanism close to the storage mechanism will bring out the pipe fittings in the storage portion 22 together. After the two feeding mechanisms are closed by moving closer to each other, the fixing of the pipe fittings is realized. Therefore, as long as the driving mechanism can realize the synchronous closing movement of the two feeding mechanisms, and the driving mechanism adopted in the present invention is the first screw rod 25 and the second screw rod 26 driven by the motor 6. During the rotation of the two screw rods, the screw sleeves 27 connected to them will be driven to rotate. Since one end of the connecting rod 12 is connected to the outer side of the screw sleeve 27, and the connecting rod 12 is slidably connected inside the driving cavity, the rotation of the screw sleeve 27 is restricted in this way, so that the screw sleeve 27 displaces on the outer side of its connected screw rod, drives the connecting rod 12 to displace, and because the thread directions on the outer sides of the first screw rod 25 and the second screw rod 26 are opposite, the movement of the two screw sleeves 27 moving closer to each other or moving away from each other is realized. Moving closer to each other is the feeding process, and moving away from each other is the blanking process.

[0038] A moving port 18 is further arranged at the lower end of the storage plate 8 close to the pipe shrinking machine 7, and the connecting rod 12 close to the storage plate 8 is slidably installed in the moving port 18, which is to prevent the connecting rod 12 from being blocked by the storage plate 8.

[0039] For the feeding mechanism, in the present invention, a feeding plate 15 is used in cooperation with a slider 13 and a slide rail 14. The feeding plates 15 in the two feeding mechanisms are made to approach each other. Fitting portions 16 are provided on the sides of the two feeding plates 15 that approach each other, thus realizing the fixation of the pipe fittings. The pipe fittings are sent to the axis of the pipe shrinking machine 7 for pipe shrinking processing. When the pipe fittings are at the axis of the pipe shrinking machine 7, the two fitting portions 16 are in a state of being fitted together.

[0040] In summary, by providing an adjustment mechanism, a storage mechanism, and a feeding component, the present invention first uses the base 1 in cooperation with the adjustment mechanism to form the main body for bearing. Storage mechanisms are provided on both the adjustment mechanism and the base 1. The storage cavity between the two storage mechanisms is used to store the radiator pipe fittings to be processed. At the same time, the adjustment mechanism can drive the storage above it to move, thus realizing the adjustment of the length of the storage cavity to accommodate the placement and processing of radiator pipe fittings of different lengths, thereby improving the applicability. At the same time, the two storage mechanisms can store multiple heat dissipation pipe fittings at one time, and the heat dissipation pipe fittings will finally flow into the storage portion 22 in sequence. In this way, the operation of manually feeding single pipes is eliminated, and the processing efficiency is greatly improved. The feeding component cooperates with the storage mechanism. After there is a single pipe in the storage portion 22, it can automatically send the pipe to the axis of the pipe shrinking machine 7 to achieve automatic feeding. After the processing is completed, when the feeding mechanism retracts, the processed pipe fittings will automatically fall into the discharging port 5, thus realizing automatic loading and unloading, and greatly improving the processing efficiency of the pipe shrinking machine 7.

[0041] The above has schematically described the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they should all fall within the protection scope of the present invention.

[0042] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
