[0057] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0058] This embodiment provides a horizontal beveling machine that is convenient for loading and unloading. Figure 1 As shown, it includes: a bed 1, a pressing cylinder 3, a flap 10 and a support platform 12;

[0059] The bed 1 is provided with a fixture 2 and a fixing bracket 11. The fixture 2 is mounted on the bed 1 by bolts for easy replacement. The fixing bracket 11 is welded and fixed on the bed 1. The fixture 2 is used to place the pipe B. Figure 1 As shown, the fixing bracket 11 and the support platform 12 are located on the same side of the fixture 2, and the support platform 12 can be fixed to the ground by anchor bolts, or can be welded and fixed to one side of the bed 1;

[0060] like Figure 1 As shown, a pressure head 9 is installed on the flap 10 by bolts for easy replacement, one end of the flap 10 is hinged to the fixed bracket 11, the flap 10 is hinged to the clamping cylinder 3, and the end of the clamping cylinder 3 away from the flap 10 is rotatably connected to the support platform 12. In this embodiment, a middle swing bracket 13 is installed on the top of the support platform 12 by bolts, the clamping cylinder 3 is installed on the middle swing bracket 13, and the clamping cylinder 3 rotates on the middle swing bracket 13;

[0061] The clamping oil cylinder 3 drives the flap 10 to flip by telescoping, so that the pressure head 9 is opened or closed relative to the clamp 2;

[0062] In this embodiment, when the clamping oil cylinder 3 contracts, the flap 10 flips upward, so that the pressure head 9 is opened relative to the clamp 2. At this time, a hoisting space is formed above the clamp 2 so that the pipe B can enter and exit the clamp 2 vertically.

[0063] In this embodiment, when the clamping cylinder 3 is extended, the flap 10 flips downward, so that the pressure head 9 is closed relative to the clamp 2. At this time, the pressure head 9 and the clamp 2 can clamp the pipe B;

[0064] Different from the existing horizontal beveling machine in which a top beam for installing a clamping cylinder is arranged above the clamp, the present embodiment provides a horizontal beveling machine which is convenient for loading and unloading. The top beam is eliminated and the clamping cylinder 3 is arranged on one side of the clamp 2. When lifting and unloading are required, the clamping cylinder 3 is extended and retracted to drive the flap 10 to flip, and the pressure head 9 and the flap 10 avoid the lifting equipment for lifting the pipe fittings, so that a lifting space is formed above the clamp. The pipe fitting B enters and exits the clamp 2 vertically through the lifting space, so that the pipe fitting B can be lifted straight up and down, thereby improving the efficiency of loading and unloading the pipe fitting B.

[0065] In a specific embodiment, the bed 1 is also provided with a groove processing mechanism, such as Figure 3 As shown, the milling cutter disc 4 of the groove processing mechanism faces the fixture 2.

[0066] In a specific embodiment, one end of the flap 10 away from the fixed bracket 11 is rotatably connected to the pressing cylinder 3;

[0067] With the hinge point between the flap 10 and the fixed bracket 11 as the fulcrum, the clamping cylinder 3 applies power to the end of the flap 10 away from the fulcrum by utilizing the lever principle, which is more labor-saving, and thus a smaller-sized clamping cylinder 3 can be used.

[0068] In a specific embodiment, when the clamping cylinder 3 is extended, the pressure head 9 is closed relative to the clamp 2. At this time, the angle α between the axis of the clamping cylinder 3 and the top surface of the flap 10 is 15° to 25°. Within this angle range, it can ensure that the pressure head 9 clamps the pipe B and at the same time make the flap 10 have a sufficiently large flipping angle.

[0069] In a specific embodiment, Figures 4 to 7 As shown, the milling cutter disc 4 includes a main body 401, a slide seat 404, an adjustment bolt 418 and an adjustment nut 419;

[0070] like Figure 4 As shown, a T-slot 402 is provided on the main body 401, and the head of the adjusting bolt 418 can slide in the T-slot 402, and the screw of the adjusting bolt 418 is assembled with the adjusting nut 419 after passing through the through hole provided on the slide seat 404;

[0071] When the adjusting bolt 418 slides along the T-slot 402, the blade 413 provided on the milling cutter installed on the slide 404 moves radially along the rotation center line of the milling cutter disc 14 to adapt to pipe fittings B of different diameters;

[0072] When the slide 404 needs to be moved, the adjusting nut 419 is loosened to allow the head of the adjusting bolt 418 to slide along the T-slot 402 . When the slide 404 moves to a desired position, the adjusting nut 419 is tightened to complete locking.

[0077] The blade 413 is mounted on the blade body 412 by bolts. Figure 5 As shown in the upper part, there is an angle (edge ​​inclination) between the cutting edge of the blade 413 and the rotation center line of the milling cutter disc 4, which is used to process the groove of the pipe B;

[0078] The elastic force generated by the spring 410 keeps the guide shaft 417 and the blade 413 always close to the pipe wall of the pipe B, which is suitable for large-diameter pipes with poor roundness and uneven wall thickness, and effectively ensures the quality of the groove after processing;

[0079] By screwing the spring adjustment bolt 411 on the second top screw plate 407 , the expansion and contraction amount of the spring 410 is fine-tuned so that the guide shaft 417 fits the pipe fitting B better.

[0080] In a specific embodiment, Figure 7 As shown, the milling cutter is an end cutter, and the end cutter includes a fixing plate 405, a first top screw plate 406 and a cutter body 412;

The knife body 412 can be pressed on the fixing plate 405 by bolts installed on the first top screw plate 406;

[0082] The blade 413 is mounted on the blade body 412 by bolts. Figure 5 As shown in the lower part, the cutting edge of the blade 413 is parallel to the rotation center line of the milling cutter disc 4 (the cutting edge is horizontal) and is used to process the end face of the pipe B.

[0083] In a specific embodiment, Figure 2 and Figure 3 As shown, the groove processing mechanism includes a power head 5, a slide plate 6, a slide rail 7 and a feed cylinder 8;

[0084] The main body 401 of the milling cutter disc 4 is fixed to one end of the main shaft of the power head 5 close to the fixture 2 by a threaded fastener, and the radial direction of the main shaft of the power head 5 is the radial direction of the rotation centerline of the milling cutter disc 4;

[0085] One side of the slide plate 6 is fixedly connected to the power head 5 by bolts, and the other side of the slide plate 6 is fixed with a slider by bolts, and the slider is installed on the slide rail 7;
