Description

Technical Field

[0001] This application relates to the field of pipe processing, and in particular to an automatic feeding mechanism for pressure pipes. Background Technology

[0002] In the diverse landscape of manufacturing, pipe processing occupies a vital position. With its unique hollow structure, pipe possesses advantages such as light weight and high strength, and is widely used in numerous fields including machinery manufacturing, construction engineering, automotive industry, and aerospace. Common pipe processing encompasses various techniques such as cutting, bending, flaring, necking, and welding. Cutting allows for precise separation of pipes to the required length; bending imparts specific shapes to pipes; and welding is used to connect pipes to meet the structural requirements of different products, providing fundamental support for product manufacturing across various industries.

[0003] When tubes are bent or punched, they need to be fixed on a fixture. To improve production efficiency, automatic clamping is usually used to fix them and achieve fully automated production. Therefore, tubes need to be continuously output one by one during feeding. Existing automatic feeding mechanisms generally output from the bottom, which makes the tubes easy to get stuck and the feeding is not smooth enough. Summary of the Invention

[0004] In order to improve the technical problems of easy jamming of pipes and insufficient feeding in existing automatic feeding mechanisms, this application provides an automatic feeding mechanism for pressure pipes.

[0005] The automatic pressure tube feeding mechanism provided in this application adopts the following technical solution:

[0006] An automatic pressure tube feeding mechanism includes a frame, with a hopper at the upper end of the frame. The bottom of the hopper consists of a feeding inclined plate, a middle inclined plate, and a discharging inclined plate. The upper end of the middle inclined plate is directly above the lower end of the feeding inclined plate, and the upper end of the discharging inclined plate is directly above the lower end of the middle inclined plate. A V-shaped receiving component is provided below the discharging inclined plate. Several equally spaced top material holes are provided at the connection between the feeding inclined plate and the middle inclined plate, as well as at the connection between the middle inclined plate and the discharging inclined plate. A lifting mechanism is provided below the top material holes.

[0007] By adopting the above technical solution, one lifting mechanism lifts the pipe material on the feeding ramp and makes it slide down the middle ramp, while the other lifting mechanism lifts the pipe material on the middle ramp and makes it slide down the discharge ramp to the V-shaped receiving part. This realizes the supply of a single pipe material, which makes it convenient for the robot to grab the pipe material. Moreover, the pipe material is lifted twice, which can reduce the impact of repeated feeding or lack of material on the pipe material supply during a single lifting. Furthermore, lifting the pipe material upward can prevent the pipe materials from getting stuck together, further improving the stability of the material supply.

[0008] Preferably, two parallel circular rods are fixed in the middle of the hopper, and two clamping plates are slidably arranged on the circular rods, with the bottom of the clamping plates matching the bottom of the hopper.

[0009] By adopting the above technical solution, both clamping plates can slide along the round rod, and the distance between them is adjustable, which can be applied to pipes of different lengths, ensuring that the pipes are neat and improving the stability of material supply.

[0010] Preferably, the lifting mechanism includes a mounting frame fixed on the frame. The mounting frame is square, and a lifting cylinder is installed at the lower end of the mounting frame. A lifting plate is fixed on the output shaft of the lifting cylinder. A plurality of sliding holes are opened at the upper end of the mounting frame, and a push rod is slidably arranged in the sliding holes. The lower end of the push rod is fixed on the lifting plate, and the upper end of the push rod is an inclined surface.

[0011] By adopting the above technical solution, multiple jacking rods are used, which can prevent the pipe from tilting to one side when jacking the pipe.

[0012] Preferably, a mounting base is fixed on the frame, the mounting base is located at the side end of the V-shaped receiving part, a lateral positioning cylinder is mounted on the mounting base, a push block is fixed on the output shaft of the lateral positioning cylinder, and the push block is aligned with the V-shaped receiving part.

[0013] By adopting the above technical solution, when the tube rolls down from the discharge ramp, it is difficult to ensure that the end position of the tube does not change. After the tube falls onto the V-shaped receiving part, the lateral positioning cylinder drives the push block to push the tube to one side, which can ensure the accuracy of the end position of the tube, improve the accuracy of the feeding position, and help improve the quality of subsequent processing.

[0014] Preferably, the bottom of the frame is provided with a number of fixed corner brackets, and the fixed corner brackets are distributed at equal intervals.

[0015] By adopting the above technical solution, the frame can be fixed to the ground using fixed angle brackets, thus improving stability during use.

[0016] Preferably, an infrared sensor is installed at the bottom of the hopper, and the infrared sensor faces the lower end of the feeding ramp.

[0017] By adopting the above technical solution, when there is no pipe material on the feeding ramp, the operator can be promptly prompted to replenish the pipe material through alarms or remote signal transmission. The remaining pipe material on the intermediate ramp can provide a buffer time for replenishing the pipe material, thus facilitating operation.

[0018] Preferably, a baffle is fixed at the upper end of the frame, and the distance between the lower end of the baffle and the middle inclined plate is sufficient for a single pipe to pass through.

[0019] By adopting the above technical solution, the baffle can ensure that only one pipe enters the intermediate inclined plate when the lifting mechanism lifts multiple pipes at the same time, thus ensuring the uniform distribution of pipes in the intermediate inclined plate and improving the stability of material supply.

[0020] Preferably, a lifting block is slidably arranged on the inner side of the clamping plate, a horizontal partition is fixed at the upper end of the lifting block, and an inclined support rod is fixed at the lower end of the lifting block. The inclined support rod is located directly above the lower end of the feeding inclined plate, and the horizontal partition is located directly above the upper end of the middle inclined plate.

[0021] By adopting the above technical solution, when there are pipes of substandard length placed on the feeding inclined plate, when the push rod lifts the shorter pipe, only one end of the shorter pipe can be squeezed to the inclined support rod. The end squeezed to the inclined support rod can lift the horizontal partition, but the other end will be blocked by the horizontal partition and will not enter the middle inclined plate, thus preventing the production of substandard pipes.

[0022] Preferably, the clamping plate has a vertically arranged long slot, and two threaded pins are fixed on the lifting block. The threaded pins pass through the long slot and are threaded with nuts, which are located on the outside of the clamping plate.

[0023] By adopting the above technical solution, the two threaded pins enable the lifting block to slide up and down along the long slot, and it is installed by two nuts. The structure is simple, occupies little space, and is easy to use.

[0024] Preferably, the lifting block is threaded with fastening bolts, and the cross plate has mounting holes and is fixed to the lifting block by fastening bolts.

[0025] By adopting the above technical solution, the diaphragm is tightened and fixed on the lifting block by fastening bolts, which is convenient to replace. When processing pipes of different lengths, diaphragms of different lengths can be replaced, which can both ensure the obstruction of shorter pipes and prevent the two diaphragms from colliding with each other.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The lifting mechanism lifts the pipe material upwards to achieve feeding, which can prevent the pipe material from blocking each other. Moreover, the pipe material is lifted twice, which can improve the uniformity of the distribution of the pipe material on the middle inclined plate. In turn, the stability of feeding is improved during the second lifting, making the overall feeding smoother and more stable. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0036] This application discloses an automatic pressure tube feeding mechanism.

[0037] Example 1:

[0038] Reference Figures 1-5An automatic pressure tube feeding mechanism includes a frame 1. The bottom of the frame 1 is provided with several evenly spaced fixed angle brackets 18. A hopper 2 is located at the upper end of the frame 1. The bottom of the hopper 2 consists of a feeding inclined plate 3, a middle inclined plate 4, and a discharging inclined plate 5. The upper end of the middle inclined plate 4 is directly above the lower end of the feeding inclined plate 3, and the upper end of the discharging inclined plate 5 is directly above the lower end of the middle inclined plate 4. A baffle 20 is fixed at the upper end of the frame 1, and the distance between the lower end of the baffle 20 and the middle inclined plate 4 allows a single tube to pass through. Two parallel circular rods 8 are fixed in the middle of the hopper 2, and two sliding rods 8 are mounted on the circular rods 8. The clamping plate 9 is matched with the bottom of the hopper 2. A V-shaped receiving part 6 is provided below the discharge inclined plate 5. A mounting base 15 is provided on the side of the V-shaped receiving part 6. A lateral positioning cylinder 16 is installed on the mounting base 15. A push block 17 is fixed on the output shaft of the lateral positioning cylinder 16. Several equally spaced top material holes 7 are provided at the connection between the feeding inclined plate 3 and the intermediate inclined plate 4, as well as at the connection between the intermediate inclined plate 4 and the discharge inclined plate 5. A lifting mechanism is provided below the top material holes 7. An infrared sensor 19 is installed at the bottom of the hopper 2, and the infrared sensor 19 faces the lower end of the feeding inclined plate 3.

[0039] With the above settings, the frame 1 can be fixed to the ground by fixing the angle bracket 18 before use, improving the stability during use. During use, first adjust the distance between the two clamping plates 9 to match the length of the pipe to ensure the pipe is neat. One lifting mechanism lifts the pipe on the feeding ramp 3, causing it to slide down the middle ramp 4. Furthermore, the baffle 20 ensures that only one pipe enters the middle ramp 4 when the lifting mechanism simultaneously lifts multiple pipes. The other lifting mechanism lifts the pipe on the middle ramp 4, causing it to slide down the discharge ramp 5 onto the V-shaped receiving part 6. Then, the lateral positioning cylinder 16... The pusher block 17 pushes the pipe to one side, ensuring the accuracy of the pipe's position and thus enabling the supply of individual pipes. This facilitates the robotic arm's gripping of the pipes. Furthermore, the pipes are lifted twice, reducing the impact of repeated feeding or material shortages during a single lift on the pipe supply. Lifting the pipes upwards also prevents them from jamming together, further improving the stability of the supply. When there are no pipes on the feeding ramp 3, the operator can be promptly alerted to replenish the pipes via an alarm or remote signal transmission. The remaining pipes on the intermediate ramp 4 provide a buffer time for replenishment, thus facilitating operation.

[0040] Reference Figure 4 The lifting mechanism includes a square mounting frame 10 fixed on the frame 1. A lifting cylinder 11 is installed at the lower end of the mounting frame 10. A lifting plate 14 is fixed on the output shaft of the lifting cylinder 11. A plurality of sliding holes 12 are provided at the upper end of the mounting frame 10. A push rod 13 is slidably arranged in the sliding holes 12. The lower end of the push rod 13 is fixed on the lifting plate 14, and the upper end of the push rod 13 is an inclined surface.

[0041] With the above configuration, the top rod 13, under the action of the lifting cylinder 11, can lift the pipe material above it upward. Since the upper end of the top rod 13 is an inclined surface, the pipe material has a tendency to move laterally. Therefore, the pipe material moves upward along the vertical bottom wall of the hopper 2. When the pipe material is higher than the middle inclined plate 4 or the discharge inclined plate 5, it will roll towards the middle inclined plate 4 or the discharge inclined plate 5, thereby realizing the feeding.

[0042] The implementation principle of this embodiment is as follows:

[0043] The lifting cylinder 11 drives the bottom pipe of the feeding inclined plate 3 to move upward, and when it is higher than the middle inclined plate 4, it rolls onto the middle inclined plate 4. The baffle 20 ensures that only one pipe enters the middle inclined plate 4 at a time, ensuring that the material on the middle inclined plate 4 is neatly arranged. Then another lifting cylinder 11 repeats the same step, lifting the pipe until it rolls along the discharge inclined plate 5 into the V-shaped receiving part 6. After that, the lateral positioning cylinder 16 drives the push block 17 to push the pipe to one side, ensuring that the pipe is accurately positioned. This improves the smoothness of the feeding process while ensuring the accuracy of the feeding position.

[0044] Example 2:

[0045] Reference Figure 3 and Figure 6 The clamping plate 9 has a vertically arranged long slot 24. A lifting block 21 is slidably arranged on the inner side of the clamping plate 9. Two threaded pins 25 are fixed on the lifting block 21. The threaded pins 25 pass through the long slot 24 and are threaded with nuts 26. The nuts 26 are located on the outer side of the clamping plate 9. A horizontal partition 23 is fixed to the upper end of the lifting block 21 by fastening bolts 27. An inclined support rod 22 is fixed to the lower end of the lifting block 21. The inclined support rod 22 is located directly above the lower end of the feeding inclined plate 3. The horizontal partition 23 is located directly above the upper end of the middle inclined plate 4.

[0046] With the above settings, when a pipe of substandard length is placed on the feeding inclined plate 3, the push rod 13 will lift the shorter pipe. Only one end of the shorter pipe can be squeezed to the inclined support rod 22. The end squeezed to the inclined support rod 22 can lift the horizontal partition 23, but the other end will be blocked by the horizontal partition 23 and will not enter the middle inclined plate 4, thus preventing the production of substandard pipes.

[0047] The implementation principle of this embodiment is as follows:

[0048] For pipes that meet the length requirements, both ends can abut against the inclined support rods 22 on the two clamping plates 9, pushing the inclined support rods 22 upward. At the same time, the transverse partition 23 will also be raised upward, without hindering the rolling of subsequent pipes. However, when the length of the pipe does not meet the requirements (if the operator does not identify it when feeding), the shorter pipe (the longer pipe cannot be put in) can only abut against the inclined support rod 22 at most at one end. The transverse partition 23 at the other end will prevent it from rolling onto the middle inclined plate 4, thus rejecting the pipes that do not meet the length requirements.

[0049] In summary, this device can prevent pipe material from getting stuck by discharging material from the top, and the double-top feeding mechanism ensures that the pipe material is neatly arranged, thus improving the smoothness of the feeding process.

[0050] 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.
