Description

Technical Field

[0001] This utility model relates to the technical field of pipe processing, and more specifically, to a pipe feeding device and a flaring and stamping equipment. Background Technology

[0002] Pipes are widely used in the manufacture of structural components and mechanical parts. During the use of pipes, processing techniques such as cutting, bending, and necking are frequently required to meet the length and shape requirements of different applications. Before secondary processing, pipes generally need to be loaded into a feeder. Using a feeding device instead of manual loading is an effective way to improve processing efficiency, save manpower, and enhance operational safety.

[0003] Chinese invention patent application CN117088080A discloses an automatic pipe feeding device, including a stacking mechanism and a feeding mechanism. The stacking mechanism includes a material receiving chamber with a downwardly inclined bottom wall. A material sorting mechanism is provided inside the material receiving chamber, which includes a sorting plate and a sorting drive assembly. The sorting plate is composed of a baffle and a pressure plate connected at their ends. The baffle and the material receiving chamber enclose a stacking cavity. The pressure plate is arranged parallel to the bottom wall of the material receiving chamber and encloses a discharge cavity. A discharge port is provided on one side of the discharge cavity. The sorting drive assembly is installed on the material receiving chamber and is connected to the sorting plate, which can drive the sorting plate to reciprocate along the inclined direction of the bottom wall of the material receiving chamber. The feeding end of the feeding mechanism is located on one side of the discharge port and transports the pipe to the unloading end on the other side.

[0004] The aforementioned automatic pipe feeding device uses a material feeding drive assembly connected to a material feeding plate, which drives the material feeding plate to reciprocate along the inclined direction of the bottom wall of the material receiving chamber. This controls the stable distribution of pipes, avoids pipe jamming, and ensures efficient pipe feeding.

[0041] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0042] On the one hand, such as Figure 1 and Figure 2 , Figure 3 As shown, a pipe feeding device according to one embodiment of the present invention includes:

[0043] The hopper component 1 includes a hopper frame 11 with a discharge port 101 at the bottom and a limiting unit 12 disposed at the discharge port 101. The limiting unit 12 includes a limiting plate 121 adapted to the discharge port 101 and a limiting drive 122 for driving the limiting plate 121 to switch the opening and closing state of the discharge port 101.

[0044] The discharge component 2 includes a discharge trough 21, an inclined roller trough 22, and a guide component 23 disposed above the discharge trough 21. The guide component 23 and the discharge trough 21 form a discharge channel. The roller trough 22 is disposed below the discharge channel and has a discharge port 201.

[0045] The feeding component 3 includes a baffle block 31 located at the end of the discharge port 201, a lifting component 32 located below the discharge port 201, and a feeding drive component 33 that drives the lifting component 32 to move up and down.

[0046] The aforementioned pipe feeding device achieves full-process automation of material limiting, guiding, and lifting through the linkage of hopper component 1, discharge component 2, and feeding component 3. It overcomes the technical problems of easy jamming and inaccurate positioning when feeding slender pipes. It has a simple structure, occupies little space, and is suitable for the production environment of small pipes.

[0047] Specifically, the hopper component 1, through the cooperation of the limiting plate 121 and the limiting drive component 122, dynamically adjusts the opening and closing state of the discharge port 101 to avoid pipe accumulation and blockage, ensuring that a single pipe falls in an orderly manner, thus solving the problem of unstable discharge in traditional devices; the discharge channel formed by the guide component 23 and the discharge trough 21 of the discharge component 2 constrains the single-row movement of the pipe, and the inclined rolling trough 22 uses gravity to realize the automatic rolling of the pipe to the discharge port 201, which, together with the guide component 23, prevents deviation and significantly improves the pipe arrangement accuracy and conveying smoothness; the baffle block 31 of the feeding component 3 accurately intercepts the pipe, and the lifting component 32 lifts the pipe smoothly to the processing position through lifting and lowering motion. Combined with the flexible control of the feeding drive component 33, non-destructive automated feeding is realized, reducing the need for manual intervention, and is especially suitable for precision pipes with easily damaged surfaces.

[0048] In one embodiment, the hopper component 1 further includes a material separating assembly 13 and a material pushing assembly 14. The length of the hopper frame 11 is at least twice the length of the pipe, and the hopper frame 11 has a clearance groove in the middle. The material separating assembly 13 includes a material separating plate 131 adapted to the clearance groove, and a material separating cylinder 132 that drives the material separating plate 131 to move up and down in the clearance groove. The material separating plate 131 divides the inner cavity of the hopper frame 11 into a first material cavity and a second material cavity. The material pushing assembly 14 includes a material pushing plate 141 disposed on the wall of the second material cavity of the hopper frame 11, and a material pushing cylinder 142 that drives the material pushing plate 141 to move along the length direction of the hopper frame 11. Thus, the hopper is divided into a first material chamber and a second material chamber by the partition plate 131, realizing dual-chamber zone management and increasing the storage space; at the same time, the pusher cylinder 142 drives the pusher plate 141 to move along the length direction in the second material chamber, and with the help of the anti-cavity groove structure, ensures that the pipe in the second material chamber is pushed to the discharge port, completing the automated operation of transporting the pipe in the second material chamber to the first material chamber.

[0049] In one embodiment, a roller unit is provided at the bottom of the second material chamber. In this way, the roller unit reduces the contact area between the pipe and the bottom of the hopper frame 11, avoiding scratches on the surface of the pipe during the pushing process; at the same time, the rotation of the roller guides the pipe to move in a preset direction, preventing the pipe from deviating or getting stuck.

[0050] In one embodiment, the discharge trough 21 includes a first trough 211 and a second trough 212, which are arranged in a Z-shape with the first trough 211, the second trough 212, and the rolling trough 22. Thus, the first trough 211, the second trough 212, and the rolling trough 22 form a Z-shaped path, utilizing the pipe's own weight to achieve continuous rolling and reduce power consumption. Simultaneously, the Z-shaped structure extends the material flow path within a limited space, avoiding impact collisions caused by straight-line rolling and protecting the integrity of the pipe's end face.

[0051] In one embodiment, the guide member 23 is disposed above the first material trough 211, and the discharge component 2 further includes an adjustment structure 24 for adjusting the height of the guide member 23. The adjustment structure 24 includes adjustment brackets disposed on both sides of the first material trough 211, and the adjustment brackets are provided with elongated slots. The guide member 23 is connected to the adjustment brackets through the elongated slots via fixing members. In this way, the height of the guide member 23 can be quickly adjusted by cooperating with the fixing members via the elongated slots to match the guiding requirements of pipes with different diameters. At the same time, the distance between the guide member 23 and the discharge trough 21 is precisely controllable, preventing the pipe from tipping over or misaligning during rolling, and improving the stability of the discharge channel.

[0052] In one embodiment, the guide element 23 is a bent steel strip. Thus, the bent steel strip combines strength and flexibility, reducing the overall weight of the equipment and minimizing wear and tear on the pipes. Furthermore, the one-piece molding process simplifies the manufacturing process and reduces replacement and maintenance costs.

[0053] In one embodiment, both the limiting drive 122 and the feeding drive 33 are driving cylinders. This ensures a fast cylinder drive response, guaranteeing coordinated opening and closing of the limiting plate 121 and lifting / lowering of the lifting component 32, thus preventing material supply interruptions.

[0054] In one embodiment, the baffle block 31 has an inclined surface that matches the inclination angle of the roller groove 22. Thus, the inclined surface is at the same angle as the roller groove 22, and the impact force when the pipe contacts the material is decomposed into lateral sliding, avoiding rebound or damage caused by hard collisions.

[0055] In one embodiment, the lifting member 32 is provided with a discharge surface adapted to the inclined surface. In this way, the discharge surface and the inclined surface of the stop block 31 form a continuous support surface, and there is no suspended section during the lifting of the pipe, which prevents bending and deformation; the discharge surface of the lifting member 32 automatically adjusts the contact angle according to the diameter of the pipe to ensure that the lifting force is evenly distributed and reduce the risk of slippage.

[0056] On the other hand, such as Figure 4As shown, a flaring and stamping device according to one embodiment of the present invention includes a pipe feeding device 4, a clamping device 5 with a clamping cavity, and a stamping device 6; the pipe feeding device 4 transports the pipe to the clamping cavity of the clamping device 5, and the stamping device 6 performs a flaring and stamping action on the pipe in the clamping cavity.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
