Detailed Description of the Invention

[0018] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0019] As Figure 1 , Figure 2 shown, the metal pipe end expansion device provided by the embodiment of the present application has a structure including a frame 1, a feeding mechanism 2 arranged on the frame 1, an expanding mechanism 3 and a receiving mechanism 4. The expanding mechanism 3 includes a fixed seat 31 arranged on the frame 1, a bracket 32 located on the side of the fixed seat 31, a lifting and receiving component 33 arranged on the fixed seat 31, a horizontal impact component 34 arranged on the bracket 32, and a pressing and transferring component 35 arranged on the bracket 32. The pressing and transferring component 35 includes a linear module 351 arranged along the X direction, a moving frame 352 arranged at the output end of the linear module 351, a first cylinder 353 arranged vertically on the moving frame 352 with the output end facing downwards, a pressing plate 354 arranged at the output end of the first cylinder 353, and an electromagnet 355 arranged on the lower end surface of the pressing plate 354. An upper semi-circular groove 301 is arranged on the lower end surface of the electromagnet 355, and a lower semi-circular groove 302 corresponding to the upper semi-circular groove 301 is arranged on the upper end surface of the lifting and receiving component 33.

[0020] During actual use, the pipe 100 rolls freely along the feeding mechanism 2 towards the expanding mechanism 3. Subsequently, the lifting and receiving component 33 rises to receive the pipe 100. Then, the first cylinder 353 drives the pressing plate 354 to move downwards, so that the electromagnet 355 presses the pipe 100 from above, and the non-expanded part of the pipe 100 is fixed by the upper semi-circular groove 301 and the lower semi-circular groove 302. Subsequently, the horizontal impact component 34 expands one end of the pipe 100. After completion, the electromagnet 355 adsorbs the pipe 100, the first cylinder 353 drives the pressing plate 354 to rise, so that the electromagnet 355 lifts the pipe 100. The linear module 351 drives the moving frame 352 to move above the receiving mechanism 4, and the electromagnet 355 demagnetizes to place the pipe 100 in the receiving mechanism 4. At the same time, the lifting and receiving component 33 moves downwards to receive the material.

[0021] In the above design, the pipe 100 can be conveyed to the lifting and receiving component 33 while the pipe 100 is being unloaded, which can improve the orderliness of the unloading of the expanded pipe 100.

[0022] Specifically: As Figure 2 and Figure 3As shown in the figure, the lifting and material receiving assembly 33 includes a fixing plate 331 provided on the fixed seat 31, a second cylinder 332 provided on the fixing plate 331 with its output end facing upward, and a material receiving seat 333 provided at the output end of the second cylinder 332. The material receiving seat 333 includes a first block 3331 close to the feeding mechanism 2 and a second block 3332 located on the side of the first block 3331 opposite to the material collecting mechanism 4. The lower semi-circular groove 302 is provided on the second block 3332. The upper end surface of the first block 3331 is set as an inclined surface 303 inclined towards the second block 3332, and the lower end of the inclined surface 303 is docked with the lower semi-circular groove 302. As Figure 5 shown in the figure, the feeding mechanism 2 includes a feeding plate 21 inclined towards the first block 3331 and provided on the frame 1, and baffles 22 respectively provided on both sides of the feeding plate 21. The first block 3331 is slidably and vertically connected to the end of the feeding plate 21.

[0023] During actual use, when it is necessary to receive materials through the material receiving seat 333, the second cylinder 332 drives the material receiving seat 333 to descend, so that the upper end of the inclined surface 303 of the pipe 100 slides to be flush with the end of the feeding plate 21. When the axis of the pipe 100 to be processed enters the inclined surface 303, it rolls into the lower semi-circular groove 302, and the second cylinder 332 drives the material receiving seat 333 to rise to prevent the subsequent pipe 100 from rolling towards the material receiving seat 333.

[0024] In the above design, the structural design of the lifting and material receiving assembly 33 and the feeding mechanism 2 can effectively realize the automatic entry of the pipe 100 into the material receiving seat 333, effectively improving the feeding efficiency of the pipe 100.

[0025] Specifically: As Figure 4 shown in the figure, the bracket 32 includes a first side plate 321 and a second side plate 322 respectively located on both sides of the fixed seat 31. The horizontal impact assembly 34 includes a stamping assembly 341 provided on the first side plate 321 and an abutting assembly 342 provided on the second side plate 322.

[0026] During actual use, one end of the pipe 100 is expanded by the stamping assembly 341, and the other end of the pipe 100 abuts against the abutting assembly 342.

[0027] In the above design, the structural design of the horizontal impact assembly 34 and the abutting assembly 342 facilitates the rapid impact on the pipe 100.

[0028] Specifically: As Figure 4As shown, the stamping assembly 341 includes a guide post 3411 slidably arranged on the first side plate 321, a connecting plate 3412 connecting the guide post 3411, a third cylinder 3413 fixedly arranged on the first side plate 321 for driving the connecting plate 3412 to move relative to the second side plate 322, and a punch 3414 arranged on the connecting plate 3412. The punch 3414 faces the abutting assembly 342.

[0029] During actual use, the third cylinder 3413 drives the connecting plate 3412 to move towards the second side plate 322, so that the punch 3414 expands the pipe 100.

[0030] In the above design, the structural design of the stamping assembly 341 can ensure the stability of the impact process, which is convenient for ensuring the impact accuracy of the pipe 100 and the service life of the stamping assembly 341.

[0031] Specifically: The material collecting mechanism 4 is a box body.

[0032] In the above design, setting the material collecting mechanism 4 as a box body is convenient for timely collecting the pipe 100.

[0033] It should be further understood in detail that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
