Referring to fig. 1-7, a pipe cutting apparatus includes: the device comprises a base, a cutter arm 1 with a cutter 101, a supporting seat 3, a blanking channel 4 and a feeding channel 5; the cutter arm 1 is arranged on the base, and a deflector rod 6 is fixedly connected to the cutter arm 1; the blanking channel 4 is arranged below the supporting seat 3, and the blanking channel 4 is communicated with the bottom of the groove 7; the feeding channel 5 is aligned with the groove 7, and a gap for the cutter 101 to pass through is formed between the feeding channel 5 and the supporting seat 3; one end of the supporting seat 3 is provided with a groove 7 for the end part of the pipe 18 to be inserted; a first sliding chute 8 and a second sliding chute 9 are formed in the supporting seat 3, the first sliding chute 8 is arranged below the groove 7, and the bottom of the groove 7 is communicated with the blanking channel 4 through the first sliding chute 8; a first elastic part 10 and a support plate 2 are arranged in the first sliding groove 8, the support plate 2 is connected with the support seat 3 through the first elastic part 10, and the support plate 2 is connected with the first sliding groove 8 in a sliding manner; a sliding block 11 is connected in the second sliding groove 9 in a sliding mode, the sliding block 11 is connected with the supporting plate 2 through a rope, and the sliding block 11 can be shifted by the shifting rod 6. Wherein, the machine base can be provided with a driving mechanism which drives the knife arm 1 to move.

Specifically, during the actual cutting process, the operator can first load the tube 18 to be cut into the feeding channel 5, and the end of the tube 18 extends into the groove 7, and the support plate 2 is located in the groove 7 and supports the end of the tube 18. The operator pushes the stage property into the clearance between the supporting seat 3 and the feeding channel 5, cuts off the pipe 18, simultaneously the deflector rod 6 pushes down the slide block 11 inside the second chute 9, the slide block 11 drags the supporting plate 2 through the rope when moving downwards along the chute, so that the supporting plate 2 is separated from the groove 7, the end part of the pipe 18 which is cut off in the groove 7 loses the support, and the pipe stably falls into the blanking device to complete blanking. After the tool 101 is lifted, the first elastic recovery pushes the support plate 2 back to the initial position, completing one working stroke. That is to say, say that above-mentioned setting, along with the in-process that cutter 101 moved down, can pull backup pad 2 for 18 tip of tubular product that are cut off lose the support, have improved unloading efficiency, and the tip that cuts off can steadily deviate from recess 7, the collision that the semi-manufactured goods bore when reducing the unloading.

The utility model provides a tubular product cutting device still includes air pump, sealed lid 13 and sealing washer 14, and the air pump passes through trachea and material loading passageway 5 and keeps away from 3 one end intercommunications of supporting seat, and sealing washer 14 fixed connection is in material loading passageway 5, and fixed mounting can be dismantled in the one end that supporting seat 3 was kept away from to sealed lid 13 at tubular product 18, and sealed lid 13, sealing washer 14 and material loading passageway 5 form airtight space. Through the setting, when the air pump starts, aerify to 5 inside of material loading passageway, formed airtight space in the material loading passageway 5, aerify 5 inside atmospheric pressure of increase material loading passageway, can impel the tubular product 18 of 5 inside of material loading passageway to supporting seat 3, realize the material loading to, propulsive force is steady in the inflatable material loading, does not need advancing device and 18 direct contact of tubular product, receives wearing and tearing when avoiding the material loading of tubular product 18.

Further, a pressure release valve 12 with an inner cavity is connected to the air pipe in series, the pressure release valve 12 comprises a valve body 15, a valve rod 16 and a second elastic part 17, the second elastic part 17 is sleeved on the valve rod 16, and the valve rod 16 is movably connected with the valve body 15; one end of the second elastic piece 17 is fixedly connected with the valve rod 16, and the other end of the second elastic piece is fixedly connected with the valve rod 16; the stem 16 is pressed into the bottom of the cavity by the lever 6. Specifically, before and during the cutting by the cutter 101, the air pump inflates the inside of the feeding passage 5 and maintains the inside of the feeding passage 5 in a high air pressure state, thereby pressing the end of the tube 18 in the groove 7. After the cutter 101 cuts off the broken end part of the pipe 18, the cutter 101 continuously moves downwards, and the deflector rod 6 presses the valve rod 16 downwards to enable the valve rod to be connected with the pressure release valve 12 to release pressure to the feeding channel 5, so that the cutter 101 is prevented from being extruded by the pipe 18 in the resetting process. After the cutter 101 is lifted, the second elastic member 17 restores the valve rod 16 due to elastic recovery, the relief valve 12 is closed, and one working stroke is completed.

The knife arm 1 can be connected with the machine base in a sliding way, and the section of the second sliding chute 9 is rectangular or U-shaped in order to correspond to the moving track of the shifting lever 6. The knife arm 1 can also be rotatably connected with the machine base, and the section of the second sliding chute 9 is arc-shaped in order to correspond to the moving track of the shifting lever 6.

In addition, a plurality of pulleys are arranged on the supporting seat 3, and the rope is attached to the pulleys, so that the rope is guided and supported by the pulleys in the sliding process, and the abrasion of the rope is reduced. The anti-slip layer is fixedly connected inside the groove 7, so that the pipe 18 is prevented from rotating and slipping when the cutter 101 contacts the pipe 18. The baffle is arranged outside the gap, so that a large amount of cuttings are prevented from being lifted in the cutting process.
