Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and more specifically, it relates to a steel pipe boring machine. Background Technology

[0002] The boring process of steel pipes is a crucial step in modern manufacturing. It is mainly used to process various high-requirement pipe parts, such as hydraulic cylinders, air cylinders, gun barrels, oil drill pipes, and energy pipelines. The process involves rotating the workpiece by the chuck driven by the spindle box and moving the turret (usually a power turret) to perform cutting.

[0003] In traditional steel pipe processing boring equipment, the cutting tool moves while the steel pipe is fixed in one position and rotates. However, this processing method may result in insufficient distance when processing long steel pipes, which will affect normal use. Furthermore, the extension length of the cutting tool is mostly adjusted using screws and adjusting holes. Since the spacing between the adjusting holes is fixed, the precision of adjusting the extension length of the cutting tool is poor, which will affect the processing quality of the steel pipe. Utility Model Content

[0008] The present invention is further configured such that bearing seats are provided on both sides of the material leakage hole and on the upper surface of the processing table, a lead screw is rotatably provided in the middle position of the two bearing seats, the lead screw is threadedly connected to the adjusting plate, and a second motor is provided at one end of the lead screw and on the outer wall of the bearing seat.

[0009] The present invention is further configured such that a housing is fixedly provided at the bottom of the processing table, and a waste bin is slidably provided inside the housing, the waste bin being located directly below the leakage hole.

[0010] The present invention is further configured such that sliders are provided on both sides of the lower end face of the waste bin, and corresponding sliding grooves are provided on the inner wall of the shell, and the sliders are slidably installed with the sliding grooves.

[0012] The present invention is further configured such that guide rods are provided on the inner wall of the movable plate on both sides, and the guide rods are slidably installed with the processing table.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a boring device for steel pipes, which has the following advantages: 1. By setting up a sliding block, a moving plate, a clamping assembly, and a cylinder, the user can use the clamping assembly to clamp and fix the steel pipe placed on the upper end of the roller. During processing, when the extension length of the tool reaches a certain range but still cannot reach the processing position, the sliding block can be moved by controlling the cylinder to allow the tool to continue to penetrate deeper, thereby increasing the processing range of the device and increasing its practicality.

[0014] 2. By setting up a material leakage hole, adjusting plate, first motor, and fastening nut, the user can control the first motor to drive the rotating rod to rotate the trapezoidal block and the cutting tool, so that the cutting tool can bore the inner wall of the steel pipe. When it is necessary to adjust the extension length of the cutting tool, the fastening nut can be rotated to make the trapezoidal block slide inside the trapezoidal groove, thereby adjusting the extension length of the cutting tool, which facilitates subsequent processing. Compared with the fixed adjustment hole, this design has more accurate adjustment precision, thereby increasing the accuracy of the device during processing.

[0015] 3. By setting up a shell, a waste bin, and a discharge hole, the debris falling from one end of the steel pipe during processing will enter the waste bin through the discharge hole. Subsequently, the waste bin can be pulled out of the shell by the cooperation of the slider and the chute, so as to facilitate the centralized recycling or treatment of the waste inside. In addition, by setting a telescopic tube on the outside of the lead screw, it can prevent debris from falling to the outside of the lead screw and thus affecting the normal movement of the adjusting plate.

[0023] More specifically, the user can use the clamping assembly 9 to clamp and fix the steel pipe placed on the upper end of the roller 4. During processing, when the extension length of the tool 17 reaches a certain range but still cannot reach the processing position, the sliding block 6 can be moved by the control cylinder 10 to move the moving plate 8 so that the tool 17 can continue to penetrate deeper, thereby increasing the processing range of the device and increasing its practicality.
