Description

Technical Field

[0001] This utility model relates to the field of beveling machine technology, specifically a double-headed beveling machine. Background Technology

[0002] Pipe beveling machines employ mechanical cutting methods to cold-work various end-face shapes required for welding pipes of different materials such as carbon steel, stainless steel, alloy steel, and cast iron. Elbow beveling machines require beveling both ends of the elbow. A search revealed a patent with publication number CN210548547U that discloses a double-head automatic rotary beveling machine. While this facilitates simultaneous beveling of both ends of the elbow and utilizes a rotatable support platform for both elbows, driving the platform's rotation is complex, and aligning the elbows after placement is difficult, potentially leading to poor beveling results at both ends. Therefore, a double-head elbow beveling machine with a simple structure, convenient alignment of the elbows before beveling, ensuring optimal beveling results at both ends, and high processing efficiency is designed.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1-6 A double-head elbow beveling machine includes a frame with a preparatory station and a beveling station at the front and rear of the frame, respectively. It also includes two parallel elbow support slots 5 and a rotary operating mechanism that drives the two elbow support slots 5 to alternate between the preparatory station and the beveling station. The preparatory station includes two symmetrically arranged alignment mechanisms. The beveling station has two symmetrically arranged beveling mechanisms capable of feed movement and a clamping mechanism located between the two beveling mechanisms. Furthermore, the beveling station has two symmetrically arranged infrared probes for calibrating both ends of the elbow to ensure uniform processing depth at both ends and prevent over-processing at one end and under-processing at the other.

[0026] Specifically, the alignment mechanism includes an alignment drive cylinder 7 fixedly mounted on the frame. The output shaft of the alignment drive cylinder 7 is fixedly mounted with an alignment push plate 8. The alignment drive cylinder 7 can easily drive the alignment push plate 8 to move towards the port side of the elbow. With the cooperation of the two alignment mechanisms, the elbow is placed in the elbow support groove 5 at the preparatory position.

[0027] Specifically, the beveling mechanism includes a beveling feed frame 11 that can feed towards the bend end of the bend support 5, which is moved to the beveling station. A rotating disk 14 with a beveling cutter head 15 is rotatably connected to the beveling feed frame 11 via a beveling motor 13. When the beveling motor 13 is started, the rotating disk 14 and the beveling cutter head 15 are rotated as a whole. When the rotating disk 14 is moved towards the bend end of the bend support 5 at the beveling station, beveling can be performed circumferentially at the end of the bend. The mechanism also includes a splash shield 16 disposed outside the rotating disk 14. The splash shield 16 is fixedly installed on the rotating disk 14 to facilitate the splashing of debris during beveling, so that the debris can be concentrated and fall downwards.

[0028] Specifically, the frame includes a bevel feed drive cylinder 12 that drives the bevel feed frame 11 to perform feed movements. A guide rod 17 is fixedly installed on the bevel feed frame 11, and a guide seat 18 that is slidably connected to the frame is slidably fitted on the guide rod 17. The bevel feed drive cylinder 12 facilitates the bevel feed frame 11 to perform feed movements. The cooperation between the guide rod 17 and the guide seat 18 facilitates the guidance of the bevel feed frame 11 and increases the stability of the feed movement.

[0029] Specifically, the rotary operating mechanism includes an operating table 3 fixedly mounted on the frame. A rotary seat 4 is rotatably connected to the operating table 3 via a rotary motor 6. Two elbow brackets 5 are fixedly mounted on the rotary seat 4. Starting the rotary motor 6 facilitates the rotation of the rotary seat 4 and the two elbow brackets 5. Furthermore, both the rotary motor 6 and the bevel motor 13 are configured as servo motors.

[0030] Specifically, the frame includes a base frame 1 and a bevel housing 2 fixedly installed on the top of the base frame 1. The operating table 3 is fixedly installed on the base frame 1. The bevel feed drive cylinder 12, the guide seat 18 and the alignment drive cylinder 7 are all fixedly installed on the bevel housing 2. The base frame 1 and the bevel housing 2 facilitate the support of the entire equipment.

[0031] Specifically, the clamping mechanism includes a clamping block 10 fixedly mounted on the base frame 1 via a clamping drive cylinder 9. By activating the clamping drive cylinder 9, the clamping block 10 can be easily lifted and lowered, thereby facilitating the clamping of the elbow on the elbow support groove 5 that has been moved to the beveling station, further improving the stability of the elbow beveling process.
