[0002] Steel pipes need to be cut during processing to facilitate use in different occasions. Nowadays, pipe cutting machines are used to cut steel pipes. When cutting, the steel pipes need to be fed into the feed port of the cutting machine. In the prior art, simple mechanical equipment is used to manually assist in feeding, which has low feeding efficiency and high labor intensity.

[0003] Patent 202020393062.4 discloses a simple pipe feeding device, including a material rack, on which a plurality of feeding racks are slidably connected, the feeding racks can move along the length direction of the material rack, and the material rack is also connected to an oblique push mechanism corresponding to the feeding rack, the oblique push mechanism includes a linear drive fixedly connected to the material rack, the linear drive is connected to a push rod extending in the direction of the feeding rack and capable of reciprocating linear movement, the end of the push rod extending outward is fixedly connected to the push rack, and the push rack is slidably connected to the material rack. This patent realizes efficient feeding of pipes of different specifications and reduces labor intensity by jointly setting an oblique push mechanism and a feeding rack. In this patent, the pipe feeding device is installed at 90° through the front end of the feeding plate and the limit block 11, thereby forming a V-groove, and the pipe is in the V-groove. This pipe feeding device has the following problems: after reaching the feeding position, when the height from the center of the pipe cutting machine chuck to the upper surface of the fuselage guide rail is low (such as Figure 1 As shown in the figure), after the pipe cutting machine support 12 lifts the pipe, the bottom of the pipe is still lower than the tip of the limit block 11, causing the feeding device to be unable to return to the initial position. Utility Model Content

[0004] The utility model aims to provide a movable pipe feeding device to solve the problems existing in the prior art.

[0005] The purpose of the utility model is achieved as follows: a movable pipe feeding device is arranged at the front end of a feeding plate, comprising a fixed supporting plate and a movable supporting plate, the bottoms of the fixed supporting plate and the movable supporting plate are hinged, the bottom of the movable supporting plate is arc-shaped and meshes with a guide rack, and the rear side of the guide rack is connected to a guide cylinder.

[0006] In the movable pipe feeding device of the utility model, when the feeding plate moves forward to feed the material, the telescopic rod of the guide cylinder is always in an extended state. At this time, the fixed support plate and the movable support plate are hinged to form a V-shaped support groove, and the pipe is in the V-shaped support groove; after reaching the feeding position, the pipe cutting machine support lifts the pipe, and the telescopic rod of the guide cylinder retracts, pulling the movable rack to move backward, thereby driving the movable support plate to rotate synchronously, so that the upper surface of the movable support plate is in a horizontal state, and then the feeding plate moves backward without interference. In summary, the movable pipe feeding device of the utility model can effectively avoid the situation where the feeding device cannot be reset after completing the feeding, and has the advantages of simple structure and easy installation.

[0007] As a further improvement of the utility model, the guide rack is installed in the guide groove, which includes a mounting plate and an upper guide edge and a lower guide edge connected to the upper and lower edges of the mounting plate, and the spacing between the upper guide edge and the lower guide edge is the same as the height of the main body of the guide rack. The stability of the movement of the guide rack is ensured by the guide groove.

[0008] As a further improvement of the utility model, the fixed support plate is triangular, including a vertical stop edge on the back side and a lower bevel edge on the front side. The fixed support plate and the feed plate are integrally formed, with a simple structure and easy manufacturing.

[0009] As a further improvement of the utility model, polyurethane pads are provided on the upper surfaces of the fixed supporting plate and the movable supporting plate to prevent rigid collision when the pipe is placed in the V-shaped supporting groove, thereby preventing damage to the pipe.

[0010] As a further improvement of the utility model, a pipe sensing switch is provided on one side of the fixed support plate to sense whether the pipe is placed in the V-shaped support groove, and a limit switch is provided on the other side to determine whether the feeding position is reached.

[0011] As a further improvement of the utility model, a rack cover plate is provided on the outside of the guide rack to prevent the meshing working position of the guide rack and the movable support plate from being exposed, thereby ensuring safe use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] like Figure 2-5 The movable pipe feeding device shown is arranged at the front end of the feeding plate 1, and includes a fixed supporting plate 2 and a movable supporting plate 3. The fixed supporting plate 2 and the movable supporting plate 3 form a V-shaped supporting trough. Among them, the fixed supporting plate 2 is triangular, including a vertical stop edge located on the back side (used for pre-positioning the pipe before transferring to the V-shaped supporting trough, facilitating the operation of the pushing mechanism) and a lower bevel located on the front side. The fixed supporting plate 2 and the feeding plate 1 are integrally formed, with a simple structure and easy manufacturing. The bottoms of the fixed supporting plate 2 and the movable supporting plate 3 are hinged, and the bottom of the movable supporting plate 3 is arc-shaped and meshes with the guide rack 4, and the rear side of the guide rack 4 is connected to the guide cylinder 5.

[0020] The guide rack 4 is installed in the guide groove 6, which includes a mounting plate and an upper guide edge and a lower guide edge connected to the upper and lower edges of the mounting plate. The mounting plate is provided with a connection hole that cooperates with the fixed support plate 2. The spacing between the upper guide edge and the lower guide edge is the same as the height of the main body of the guide rack 4, so as to play a guiding role in the process of the guide rack 4 moving forward and backward, and ensure the stability of the movement of the guide rack 4.

[0021] The upper surfaces of the fixed support plate 2 and the movable support plate 3 are both provided with polyurethane pads 7 to prevent rigid collision when the pipe is placed in the V-shaped support groove, thereby preventing damage to the pipe.

[0022] like Figure 5-6 As shown, a pipe sensing switch 8 is provided on one side of the fixed support plate 2 to sense whether the pipe is placed in the V-shaped support groove, and a limit switch 9 is provided on the other side to determine whether the feeding position has been reached. A rack cover plate 10 is provided on the outside of the guide rack 4 to prevent the meshing working position of the guide rack 4 and the movable support plate 3 from being exposed, thereby ensuring safety in use.

[0023] In the movable pipe feeding device of this embodiment, during the process of the feeding plate 1 moving forward to feed the material, the telescopic rod of the guide cylinder 5 is always in an extended state. At this time, the fixed supporting plate 2 and the movable supporting plate 3 are hinged to form a V-shaped supporting groove, and the pipe is in the V-shaped supporting groove; after reaching the feeding position, the pipe cutting machine support lifts the pipe, and the telescopic rod of the guide cylinder 5 retracts, pulling the movable rack to move backward, thereby driving the movable supporting plate 3 to rotate synchronously, so that the upper surface of the movable supporting plate 3 is in a horizontal state, and then the feeding plate 1 moves backward without interference.

[0024] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
