Description

Technical Field

[0001] This utility model relates to the technical field of automatic feeding devices for round tube materials, and in particular to an automatic tube feeding device for a piston rod round steel cutting machine. Background Technology

[0002] In the field of piston rod round steel cutting, traditional pipe-feeding devices mostly employ semi-automatic or manual assistance methods to achieve the conveying and positioning of round steel. While these devices can perform basic conveying functions, they suffer from the following significant drawbacks: Insufficient automation: Most devices require manual intervention to complete positioning, clamping, and unloading operations, resulting in low production efficiency. For example, a certain automatic pipe-cutting machine's feeding device relies on manual placement of the pipe and adjustment of the positioning ring, making full-process automated control impossible. Significant safety risks: Manual operation poses safety hazards such as pinching and collisions. According to "Analysis and Troubleshooting of Metal Cutting Machine Tools," problems such as elevated hydraulic system oil temperature and valve core jamming often cause equipment malfunctions, directly threatening the safety of operators.

[0003] The efficiency bottleneck is obvious: the single-station material distribution and loading mode limits the ability to operate continuously. Utility Model Content

[0004] In order to overcome the deficiencies in the prior art and achieve the above-mentioned functions, this utility model provides an automatic tube lowering device for a piston rod round steel cutting machine.

[0005] This utility model is achieved through the following technical solution: An automatic tube feeding device for a piston rod round steel cutting machine includes a feeding box with walls that gradually decrease in size from top to bottom. The bottom of the front end plate and the rear end plate of the feeding box are respectively provided with port a and port b, and the diameter of port a is larger than the diameter of the round steel material. It also includes a horizontally rotatable guide rod, which can extend into the feed box through ports a and b and the opening on the side wall of the feed box when rotating. The guide shaft of the guide rod is fixed to the vertical surface of the base plate b via bearing seat a. A bevel gear a is fixed to the end of the guide shaft. A servo motor is installed on the base plate b. The bevel gear b fixed on the output shaft of the servo motor meshes with the bevel gear a. The guide rod rotates from port b to port a.

[0006] Furthermore, it also includes a top plate fixed by four support columns, with a square groove running vertically through the middle of the top plate, through which the upper part of the feed box passes. Fixed plates are installed at both ends of the feed box, and the bottom of the fixed plates are fixedly connected to the top plate through several dampers.

[0007] Furthermore, a vibrator is fixed on the inclined side wall of the feed box.

[0008] Furthermore, the servo motor is equipped with an encoder, and the output shaft of the servo motor passes through a bearing seat b fixed on the horizontal surface of the base plate b.

[0009] Furthermore, the port b is at the same height as the guide rod and is square-shaped.

[0010] Furthermore, the bottom of the feed box is a semi-circular structure adapted to the round steel, and a stabilizing block is installed below the feed box to embed and wrap the semi-circular structure. The stabilizing block is L-shaped and fixed on the base plate a.

[0011] Furthermore, the spacing between the various rods of the guide rod within the feed box is adapted to the length of the round steel material.

[0012] The beneficial effects of this utility model are: This invention can automatically complete the tube lowering process. Compared with the existing rolling tube lowering process, this invention can push the round steel along its axial direction. When each round steel falls, it is exactly located between each rod. The overall design is stable and ingenious. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] like Figures 1 to 4 As shown, this utility model includes a feeding box 1 with walls that gradually decrease in size from top to bottom. The bottom of the front end plate 101 and the rear end plate 102 of the feeding box 1 are respectively provided with port a1011 and port b1021. The diameter of port a1011 is larger than the diameter of the round steel material so as to facilitate the discharge of the material. It also includes a horizontally rotatable guide rod 2, which, when rotating, can extend into the feed box 1 through the openings of port a1011, port b1021, and the side wall of the feed box 1. The guide shaft 201 of the guide rod 2 is fixed to the vertical surface of the base plate b602 via the bearing seat a202. A bevel gear a203 is fixed to the end of the guide shaft 201. A servo motor 3 is installed on the base plate b602. A bevel gear b303 fixed on the output shaft of the servo motor 3 meshes with the bevel gear a203. The guide rod 2 rotates from port b1021 to port a1011 to achieve the purpose of pushing material and lowering the tube.

[0018] It also includes a top plate 5 fixed by four support columns 502, and the top plate 5 has a square groove 501 that runs vertically through the middle, through which the upper part of the feed box 1 passes. The feed box 1 is equipped with fixing plates 4 at both ends. The bottom of the fixing plates 4 is fixedly connected to the top plate 5 through several dampers 401 to prevent vibration from being transmitted to the fixing components (such as the top plate 5), because the fixing components may be connected to conventional technologies such as transmission chains.

[0019] A vibrator 402 is fixed on the inclined side wall of the feed box 1 to prevent material squeezing and jamming.

[0020] The servo motor 3 is equipped with an encoder 301, and the output shaft of the servo motor 3 passes through the bearing seat b302 fixed on the horizontal surface of the base plate b602.

[0021] The port b1021 is at the same height as the guide rod 2 and is square-shaped to prevent the round steel from protruding outwards after it falls.

[0022] The bottom of the feed box 1 is a semi-circular structure adapted to round steel. A stabilizing block 6 is installed below the feed box 1 to embed and wrap its semi-circular structure. The stabilizing block 6 is L-shaped and fixed on the bottom plate a601 to strengthen the bottom support.

[0023] The spacing between the various rods of the guide rod 2 within the feed box 1 is adapted to the length of the round steel material. The round steel falls into the fan-shaped area between the various rods and is pushed out by the rear rod.

[0024] As is well known to those skilled in the art, the electrical control components in this utility model require PLC, relays, switching power supplies, etc. for control and output. Therefore, components such as the electrical control box are not shown in the figure. The specifications of the vibrator and the model of the damper are all existing technologies and will not be described in detail.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
