Detailed Description

The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings.

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1-4, a discharging driving structure of a pipe cutting machine includes a servo motor 1, a screw rod 2, a slide carriage 3, a carrier roller 4, a carrier roller support arm 5, a bottom plate 6, an upper bracket 7, a moving box 8, a guide rail 9, a cylinder 10, and a guide rod 11; the carrier roller is installed at one end of the carrier roller supporting arm, the other end of the carrier roller supporting arm is fixed to the top of the movable box, a square hole for the movable box to extend out is formed in the upper portion of the upper support, and the movable box moves up and down from the square hole. In order to enable the movable box to move more stably, the inner side of the upper support is fixedly provided with two sliding blocks 12, the sliding blocks are connected with the guide rails in a sliding mode, and the two guide rails are respectively fixed on two sides of the movable box.

The lower part of the moving box is opened, the cylinder is arranged in the moving box, a piston rod of the cylinder is connected with the top of the moving box, the lower part of the cylinder is fixed on the bottom plate, and the piston rod of the cylinder extends out to drive the moving box to move upwards.

The bottom plate with pass through between the upper bracket the guide bar is connected, the middle part of slide with lead screw connection, install on the upper portion of lead screw servo motor's output, servo motor fixes one side of upper bracket, servo motor drives the lead screw and rotates, and the lead screw drives the slide downstream, one side of slide with guide bar sliding connection, the one side of being connected with the slide is equipped with tow chain 13. The lower part of the moving box is fixedly provided with a connecting plate 14, the connecting plate is connected with the sliding seat through a rubber spring anti-collision block 15, and the lead screw drives the sliding seat to move up and down, so that the moving box is driven to move up and down through the rubber spring anti-collision block. The rubber spring anti-collision block can enable the whole movement process to have buffering effect like an air spring, and if the pipe deforms, the rubber spring anti-collision block can not enable the pipe to be hard to collide with the supporting roller, so that the chuck can be prevented from being damaged.

Unloading is the important component of pipe cutting machine, and he not only makes the cutting finished product collect the finished product car, and his most important function is that its drive idler can drag the tubular product part of having accomplished the cutting and be the follow-up motion from top to bottom along with the chuck is rotatory, and when cutting square pipe, the chuck can carry square pipe and be rotatory cutting, and the drive idler can drag the square pipe that the tail end has been cut this moment to follow about the rotational position of square pipe closed angle and follow. The velocity and acceleration at this point will match the motion of the chuck. No matter how the square pipe rotates, the tail end of the square pipe can be dragged by a force in the vertical direction, so that the phenomenon that the cutting precision is influenced due to the deformation of the tail end of the pipe due to gravity can be avoided.

The up-and-down movement of the driving carrier roller for discharging is realized by a servo motor, a lead screw, a guide rail, a cylinder and the like. The speed and acceleration are controlled by the CNC, whose values will match the chuck rotation speed. The cylinder not only balances the load weight generated by the self weight of the steel structure, but also serves as an air spring together with the rubber spring anti-collision block to move the auxiliary motor up and down. The connection is non-rigid, i.e. the motor always presses the cylinder to move up and down. The elastic device can protect the pipe and the chuck. In order to ensure the straightness of the up-and-down movement, guide rods are arranged at the opposite corners.

As shown in fig. 5, the pipe cutting machine with the discharge driving structure of the pipe cutting machine comprises a machine body 17 and a chuck 18, wherein a finished product discharge sliding plate 19 is arranged on the machine body, a through hole is formed in the middle of the finished product discharge sliding plate, and a carrier roller of the discharge driving structure of the pipe cutting machine extends out of the through hole, so that the discharge driving mechanism moves up and down in the rotating process of a square pipe. The concrete mounting structure of finished product unloading slide does: one end of the finished product blanking sliding plate is hinged with the machine body, and the other end of the finished product blanking sliding plate is connected with a blanking cylinder at the lower part. The blanking cylinder is started to drive the finished product blanking sliding plate to overturn and support the cut square tube, so that the square tube slides down along the finished product blanking sliding plate.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
