[0035] The working principle of the present invention is as follows: the position of the clamping mechanism 2 is adjusted according to the different diameters of different batches of workpieces 3, and the adjustment motor 214 is started to drive the adjustment gear 1 215 to rotate, which drives the adjustment gear 2 218 to rotate, drives the adjustment screw 216 to rotate, drives the adjustment seat 206 to slide on the adjustment slide rod 217, and adjusts the position of the annular frame 209 so that when the workpiece 3 is located on the pushing assembly, the workpiece 3 and the annular frame 209 are coaxial.

[0036] The workpiece 3 is placed into the processing box 101 from one side of the processing box 101, and the cutting assembly and the pushing assembly provide support for the workpiece 3. When the workpiece 3 rolls onto the pushing assembly, it contacts the lower pressing roller 114, pushing the lower pressing roller 114 to move upward and stretch the lower pressing spring 112. When the workpiece 3 is completely rolled into place, the lower pressing roller 114 is pressed on the surface of the workpiece 3 under the elastic force of the lower pressing spring 112. At this time, the workpiece 3 is located between the two rollers 110 in the pushing assembly and the cutting assembly, and the outer surface of the workpiece 3 is tangent to the four rollers 110.

[0037] Start the processing motor 204 to drive the clamping motor 205 to rotate, drive the annular guide frame 213 to rotate, drive multiple clamping rods 210 to move synchronously on the annular frame 209, all clamping rods 210 are close to the axis, drive the two grinding guide grooves 211 to move relative to each other, and drive the small grinding disc 212 to move.

[0038] Start the pushing motor 107 to drive the pushing screw 108 to rotate, drive the pushing V-shaped support plate 109 to move and drive the push plate 111 to move. The push plate 111 pushes the first end of the workpiece 3 to move toward the clamping mechanism 2 until the second end of the workpiece 3 contacts the small grinding disc 212, and then the multiple clamping rods 210 continue to retract to clamp the second end of the workpiece 3 in the middle.

[0039] At this time, the cutting motor 117 is started to drive the cutting screw 116 to rotate, drive the cutting V-shaped support plate 119 to move, drive the lifting screw 121, the lifting slide bar 122, the lifting platform 123, and the flame cutting knife 118 to move, and control the size of the workpiece 3 to be cut by moving the flame cutting knife 118. The lifting motor 120 is started to drive the lifting screw 121 to rotate, drive the lifting platform 123 to move, control the height of the flame cutting knife 118, and control the cutting position.

[0040] Start the processing motor 219 to drive the processing gear 208 to rotate, drive the ring gear 207 to rotate, drive the annular frame 209 and the annular guide frame 213 to rotate, drive the clamping rod 210 and the workpiece 3 to rotate at a constant speed, and cut the workpiece 3 with the flame cutting knife 118. During cutting, start the small grinding disc 212 to grind the pipe mouth.

[0041] After the cutting is completed, the clamping motor 205 reverses, driving the annular guide frame 213 to reverse, and the clamping rod 210 no longer clamps the workpiece 3. The cut pipe falls on the inclined support plate 201, compressing the shock-absorbing spring 202, and then the pipe slides on the inclined inclined support plate 201, and finally slides into the processing box 101, sliding in the direction of the grinding assembly until the unground pipe mouth contacts the large grinding disc 105, and the hydraulic cylinder 2 is started to drive the side pressure plate 106 to extend to press the cut pipe, and the grinding motor 104 is started to drive the large grinding disc 105 to rotate to grind the other end of the pipe. After the grinding is completed, the hydraulic cylinder 1 102 is started to retract the piston rod, driving the lower baffle 103 to move, exposing the blanking mouth, so that the ground pipe falls out.

[0042] Each time the pipe is cut, the lead screw 108 is driven to rotate at a preset angle, and the workpiece 3 is pushed toward the clamping mechanism 2 by the push plate 111 on the push assembly, so that the cut pipe mouth contacts the small grinding disc 212, and is grinded by the small grinding disc 212. The principle is the same as above, and the automatic cutting, grinding and blanking of the entire pipe can be realized.
