Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, in particular to a full-automatic pipe fitting swaging production line. Background Art

[0002] In the field of metal smelting, pipe rods are needed to stir molten metal. However, when the pipe rods are stirred in the high-temperature molten liquid for a long time, the front ends of the pipe rods will melt and become shorter. If the length of the pipe rod is too short, it cannot be used, resulting in waste. Therefore, the pipe rod needs to be lengthened after it is shortened.

[0003] The existing method is to connect a short pipe to one end of the pipe rod, and the short pipe is used to dock with other pipe rods. When a pipe rod is shortened, another pipe rod can be inserted into the short pipe, so that the pipe rod can be lengthened to avoid unnecessary waste. During processing, the short pipe needs to be inserted into one end of the pipe rod and then the connection between the short pipe and the pipe rod is extruded so that the short pipe is fixed on the pipe rod. Currently, this step is mostly carried out manually by a riveting press to swage the short pipe onto the pipe rod. First, the pipe rod is long and heavy, and the pipe rod and the short pipe need to be centered before operation, resulting in low efficiency; second, the loading and unloading of the pipe rod need to be carried out manually, resulting in a large labor intensity. Summary of the Utility Model

Multiple material receiving frames are distributed between the two integral material sliding plates. One of the integral material sliding plates is vertically fixed on the workbench, and the other integral material sliding plate is vertically arranged and slidably connected to the workbench.

Detailed implementation mode

[0029] 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. Based on the embodiments in 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.

[0030] As Figure 1 shown, a preferred embodiment of the present invention proposes a fully automatic pipe fitting crimping production line, which is composed of two parts, namely a hoist 1 and a pipe fitting processing device 2. The hoist 1 is arranged on one side of the pipe fitting processing device 2. There are several pipe fittings in the hoist 1. Then the hoist 1 will lift the pipe fittings one by one upward. After the pipe fittings reach the top surface of the hoist 1, they will be arranged neatly along the inclined plane and fall onto the pipe fitting processing device 2. Then the pipe fitting processing device 2 will fix the short pipe at the end of the pipe fitting.

[0031] As Figure 2 、 Figure 3 shown, the pipe fitting processing device 2 is composed of a workbench 21 and components such as a crimping mechanism 23, a pipe fitting pushing mechanism 24, and a short pipe pushing mechanism 25 arranged on the workbench 21. Among them, the pipe fitting pushing mechanism 24 and the short pipe pushing mechanism 25 are respectively arranged on both sides of the crimping mechanism 23. Four support frames 22 are arranged between the pipe fitting pushing mechanism 24 and the crimping mechanism 23, and the four support frames 22 are evenly distributed. The pipe fittings on the hoist 1 will fall onto the support frames 22 along the inclined plane. Each support frame 22 has a positioning groove on its top surface, and the positioning groove is a V-shaped groove for centering the pipe fittings and can meet the positioning of pipe fittings with different diameters at the same time.

[0032] Refer to Figure 5, the pipe fitting pushing mechanism 24 is composed of a sliding seat 241, a cylinder seat 242, a lower clamping slider 243, an upper clamping slider 244, a cylinder fixing block 245, a clamping cylinder 246, a pushing cylinder 5 and other components. Among them, the pushing cylinder 5 is horizontally installed and fixed on the cylinder mounting seat 4 arranged at the front end of the workbench 21. The output end of the pushing cylinder 5 is connected to the sliding seat 241. The bottom of the sliding seat 241 is horizontally slidably connected to the slide rail on the workbench 21, and the pushing cylinder 5 pushes the sliding seat 241 to slide; the cylinder seat 242 is fixed on the top of the sliding seat 241 by bolts. There is a chute on the bottom surface of the cylinder seat 242, and the top of the sliding seat 241 is slidably connected to this chute. When it is necessary to adjust the horizontal position of the cylinder seat 242, loosen the bolts and slide the cylinder seat 242 through the chute. After adjusting the position, tighten the bolts again to fix the cylinder seat 242 and the sliding seat 241.

[0033] The lower clamping slider 243 is fixed on the top of the cylinder seat 242. A guide rod is vertically fixed at each end of the lower clamping slider 243. The upper clamping slider 244 is slidably connected to the guide rod up and down. The cylinder fixing block 245 is fixed at the top of the two guide rods. The clamping cylinder 246 is vertically fixed on the cylinder fixing block 245, and the output end of the clamping cylinder 246 passes through the cylinder fixing block 245 and is connected to the upper clamping slider 244 to control the upper clamping slider 244 to move up and down along the guide rod.

[0034] A positioning groove is formed on the top surface of the lower clamping slider 243 and the bottom surface of the upper clamping slider 244. The pushing cylinder 5 controls the movement of the sliding seat 241, and one end of the pipe fitting on the support frame 22 will enter between the lower clamping slider 243 and the upper clamping slider 244. Then, the clamping cylinder 246 controls the upper clamping slider 244 to move down, and cooperates with the positioning groove to position the pipe fitting. The upper clamping slider 244 and the lower clamping slider 243 clamp the pipe fitting. Finally, the pushing cylinder 5 continues to push the sliding seat 241 to move, and pushes the pipe fitting into the crimping mechanism 23.

[0035] Reference Figure 3 , in order to ensure the alignment of the other end of the pipe fitting with the crimping mechanism 23, a centering mechanism 30 is also provided on the side of the crimping mechanism 23 away from the short pipe pushing mechanism 25 for positioning and centering the pipe fitting.

[0036] As Figure 8 shown, the centering mechanism 30 is composed of a support seat 303, a centering cylinder 301 and two jaws 302. Among them, the centering cylinder 301 is vertically fixed on the support seat 303, and the two jaws 302 are fixed on the output end of the centering cylinder 301. The centering cylinder 301 can control the two jaws 302 to rotate and close. When the two jaws 302 are closed, they can center and position the pipe fitting.

[0037] The centering cylinder 301 in this embodiment can adopt a finger cylinder.

[0038] On the opposite sides of the two clamping jaws 302, a semi-circular groove is formed. When the two clamping jaws 302 are closed, a circular hole will be formed between the two clamping jaws 302, and the pipe fitting will pass through this hole, thereby centering the pipe fitting to ensure that the pipe fitting is coaxial with the crimping mechanism 23.

[0039] As Figure 6 shown in the figure, the short pipe pushing mechanism 25 is composed of a pushing cylinder 5, a fixing frame 251, a positioning seat 252, and a push rod 253. Among them, the pushing cylinder 5 is horizontally arranged, the positioning seat 252 is fixed on the top of the fixing frame 251, and a V-shaped positioning groove is also formed on the positioning seat 252 for positioning the short pipe. The push rod 253 is horizontally arranged and connected to the output end of the pushing cylinder 5. The pushing cylinder 5 controls the movement of the push rod 253 to push the short pipe located in the positioning groove into the crimping mechanism 23, so that the short pipe is inserted into the pipe fitting.

[0040] On one side of the workbench 21, a short pipe feeding mechanism 29 is arranged. The discharging end of the short pipe feeding mechanism 29 is docked with the side surface of the positioning seat 252, and the short pipe will slide down along the inclined plane onto the positioning seat 252. And the short pipe feeding mechanism 29 can also be controlled to move up and down by a cylinder to adjust the up and down position.

[0041] As Figure 7 shown in the figure, the crimping mechanism 23 is composed of a mechanism main body 231 and a plurality of flap dies 232. Among them, there is a hole that penetrates through the front and back in the middle of the crimping mechanism 23, and the inner peripheral surface of the hole is a conical surface. The mechanism main body 231 can control the plurality of flap dies 232 to slide along the conical surface, and the sliding direction is the same as the axial direction of the mechanism main body 231. When the plurality of flap dies 232 slide along the conical surface, the plurality of flap dies 232 can move towards the center of the mechanism main body 231, so that the plurality of flap dies 232 are closed, clamping the connection part of the short pipe and the pipe fitting, and applying pressure to the outer circumference of the short pipe, causing the short pipe to deform and fixing the short pipe on the pipe fitting, so that the short pipe cannot be pulled out from the pipe fitting.

[0042] After the short pipe and the pipe fitting are fixed, the pipe fitting pushing mechanism 24 withdraws the pipe fitting from the crimping mechanism 23.

[0043] As Figure 2 shown in the figure, on one side of each of the two support frames 22, a material ejecting mechanism 28 is arranged. At the same time, on the side of each support frame 22 away from the elevator 1, a receiving rack 27 is arranged. The receiving rack 27 is used to temporarily store the processed pipe fittings. The top surface of the receiving rack 27 has an inclined plane and a limiting groove. The inclined plane extends obliquely from the side where the support frame 22 is located to the position where the limiting groove is located.

[0044] As Figure 4As shown in the figure, the ejecting mechanism 28 is composed of an ejecting cylinder 281 and a turning plate 283. The top surface of the turning plate 283 also has an inclined surface. The ejecting cylinder 281 controls the turning plate 283 to move upward. During the upward movement of the turning plate 283, the pipe fitting will be ejected from the positioning groove on the support frame 22, and then the pipe fitting will fall into the limiting groove along the inclined surface.

[0045] After a number of processed pipe fittings are stored in the limiting grooves on the receiving rack 27, they will be bundled and packed together.

[0046] Reference Figure 3 , Figure 9 , before packing, a number of pipe fittings need to be aligned. Therefore, at both ends of the workbench 21, there are also provided alignment sliding plates 26. The alignment sliding plates 26 are vertically fixed on the base 3. One of the bases 3 is fixed on the workbench 21, and the other base 3 is slidably connected to the slide rail on the workbench 21. At the same time, an alignment cylinder 6 is provided on one side of this base 3. The alignment cylinder 6 is horizontally fixed on the cylinder mounting seat 4. The output end of the alignment cylinder 6 is connected to the base 3. A plurality of receiving racks 27 are located between the two alignment sliding plates 26. Every time a processed pipe fitting falls onto the receiving rack 27, the alignment cylinder 6 will control the alignment sliding plates 26 to move. The two alignment sliding plates 26 will abut against both ends of the pipe fitting, so as to align both ends of all the pipe fittings for bundling and packing.

[0047] The above technical solution only reflects the preferred technical solution of the technical solution of the present utility model. Some changes that may be made by those skilled in the art to some parts thereof all reflect the principle of the present utility model and fall within the protection scope of the present utility model.
