Technical Field

[0001] This utility model belongs to the field of machining technology and relates to an automatic feeding device, specifically a fully automatic feeding device for heavy pipes. Background Technology

[0002] Against the backdrop of the country's vigorous promotion of high-quality development and intelligent manufacturing in the manufacturing industry, laser cutting, as a modern manufacturing technology derived from optical research, has the characteristics of stability, concentration, efficiency, and precision, and has therefore become one of the key technologies for improving the level of manufacturing.

[0003] Profiles, as a basic material, are widely used in construction, municipal engineering, petrochemicals, and machinery manufacturing. With the rapid development of manufacturing and the increasing market demands for product precision, size, and weight, traditional profile cutting production efficiency and product precision are struggling to meet market demands. Laser cutting machines, as an emerging processing equipment, offer advantages such as high production efficiency, high precision, and high automation, leading to their widespread market application. However, constrained by the size and weight of heavy-duty pipes, the stability and reliability of the automatic feeding device directly affect the cutting machine's production efficiency and automation level. Therefore, it is essential to propose a fully automatic feeding device for heavy-duty pipes. Summary of the Invention

Detailed Implementation

[0022] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0023] An innovative fully automatic feeding device for heavy pipes includes a frame 2, a feeding mechanism 3, a buffer mechanism 4, and a feeding mechanism 5. The frame includes a storage area 10 and a guide area located at the front end of the storage area. Feeding mechanisms are evenly distributed at intervals along the length of the front end of the storage area. Buffer mechanisms are fixed on both sides of the front end of the guide area along the length of the front end. A feeding mechanism is located between the two buffer mechanisms.

[0024] The storage area of ​​the frame is used to store material 1, namely heavy pipe. Under the action of the feeding mechanism, a single pipe is fed into the guide area. At this time, the pipe rolls down and onto the buffer mechanism and the feeding mechanism. The buffer mechanism descends and the feeding mechanism extends forward to complete the feeding of the steel pipe.

[0025] The frame is welded from 70×70×5 thick-walled steel pipes and includes a base frame 7, a front low upright frame 14, a middle high upright frame 11, a rear end baffle 6, a guide beam 12, a storage beam 9, a support longitudinal beam 8, and an installation beam 13. The front low upright frame, middle high upright frame, and rear end baffle are sequentially arranged at intervals from front to back on the upper part of the base frame. A guide beam is spaced between the tops of the front low upright frame and the middle high upright frame. The guide beam has an inclination angle of 1.5° and forms a guide zone to facilitate material transfer. Inside the buffer mechanism, nylon half strips for noise reduction are laid on the guide beams. Storage beams are evenly spaced and inclined between the middle and high uprights and the rear end baffle. The inclination angle of the storage beams is 2° to facilitate the rolling of the pipes to the feeding mechanism. Supporting longitudinal beams are installed at the bottom of each storage beam. The area enclosed by the storage beams, the middle and high uprights, and the rear end baffle forms a storage area. Nylon strips are laid in the storage area to buffer and reduce noise. The mounting beams are installed at the lower end of each guide beam.

[0026] The feeding mechanism is responsible for lifting a single piece of material to the buffer mechanism to achieve automatic material supply. It includes a feeding cylinder 18, a sliding plate 17, a linear guide rail 16, and a feeding plate 15. Longitudinal linear guide rails are installed on the inner sides of both ends of the high frame. A sliding plate is slidably installed on the linear guide rail. The sliding plate is driven by the cylinder rod of the feeding cylinder. The feeding cylinder is installed on the base frame. The feeding plate is installed on the sliding plate by screws. The upper end surface of the feeding plate is a sloping structure with a lower front and a higher back.

[0027] During operation, the cylinder rod of the feeding cylinder extends, driving the feeding plate to rise. The material cup placed on the inclined feeding plate is lifted, and after being unobstructed by the front high support frame, it rolls down onto the guiding area, completing the feeding of a single piece. The feeding plate has an inclination angle of 2° and is detachably connected to the sliding plate for easy replacement after wear.

[0028] The buffer mechanism is used to withstand material impact. It includes a buffer cylinder 21, a linear guide rail, and a buffer plate 20. Longitudinal linear guide rails are installed on the inner sides of both ends of the front low frame. The buffer plate is slidably installed on the linear guide rail. The buffer plate is driven by the cylinder rod of the buffer cylinder. The buffer cylinder is installed on the base frame. The buffer plate has a buffer groove 19 at its upper end. The buffer groove has a C-shaped structure for buffering and positioning the material. A pad is installed on the inner wall of the buffer groove. The pad is made of polyurethane board.

[0029] The feeding mechanism includes a servo motor 27, a dual-output reducer 28, a synchronous shaft 29, linear guides, and a feeding bracket 26. The dual-output reducer, driven by the servo motor, is mounted on a mounting beam located in the middle of the frame. Synchronous shafts are mounted at both ends of the dual-output reducer, and gears 24 are mounted on the synchronous shafts. The feeding bracket is slidably mounted on the mounting beams at both ends of the frame via transversely arranged linear guides. A rack 23, meshing with the gears, is mounted on the side of the feeding bracket. The feeding bracket includes a movable beam 22 and a triangular slot frame 25 at the end of the movable beam. A photoelectric sensor switch is embedded in the bottom of the slot of the triangular slot frame, and this photoelectric sensor switch is signal-connected to the servo motor and the buffer cylinder. The buffer slot and the triangular slot frame are arranged correspondingly.

[0030] The material is conveyed by the buffer mechanism to the feeding tray of the feeding mechanism. The feeding tray is equipped with a photoelectric sensor switch, which can automatically identify whether there is material in the feeding tray. The material is fed by a servo motor that drives the synchronous shaft to drive the feeding tray and deliver the material to the feeding position of the laser tube cutter.

[0031] In the initial state, the buffer plate of the buffer mechanism is located above the frame. After the material rolls onto the buffer trough and the triangular trough frame, the buffer trough descends and the triangular trough frame extends forward to deliver the material to the processing position.

[0032] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
