Embodiment Construction

[0014] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] As shown in the figure, the pipe expander of the present invention includes a clamp, a bracket 1, a top pressing screw 2, a pipe expansion cone 3 and a handle 4. The bracket 1 is installed on both sides of the clamp, and the bracket 1 is installed with a top Pressing screw 2, the lower part of the top pressing screw 2 is connected to the pipe expanding cone 3, the upper end of the top pressing screw 2 extends out of the arch 1 and is connected to the handle 4, the handle 4 is arranged perpendicular to the top pressing screw 2, and there is a row in the middle of the clamp for clamping Tighten the middle hole 5 of the metal tube, and set a fine-tuning mechanism at the connection between the bracket 1 and the clamp to fine-tune the concentricity of the top pressing screw 2 on the bracket 1 and the middle hole 5 .

Abstract

The invention discloses a pipe expander, which includes a clamp, a bow frame, a top pressure screw, a pipe expansion cone and a handle. The bow frame is installed on both sides of the fixture, and a top pressure screw is installed on the bow frame. Cone head, the upper end of the top pressure screw protrudes from the bow frame to connect with the handle, a row of middle holes for clamping the metal pipe is set in the middle of the fixture, and a fine-tuning mechanism is set at the connection between the bow frame and the fixture for fine-tuning the top of the bow frame The concentricity of the pressure screw and the middle hole. The pipe expander of the present invention uses the top pressure screw to press and expand the cone to expand the metal pipe clamped in the center hole. In order to adjust the position of the pipe expander, the concentricity between the top pressure screw and the middle hole is ensured. Set the fine-tuning mechanism at the connection between the bow frame and the fixture. Before processing, first press the expander cone to the upper edge of the metal pipe to correct the concentricity of the top pressure screw and the middle hole. When there is a deviation, adjust the fine-tuning mechanism until The top pressure screw is concentric with the middle hole.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a pipe expander. Background technique [0002] Pipe expander is a commonly used tool when metal pipes need to be butted or expanded. During the processing of the expander, care should be taken not to crush, crumple or fract the metal pipe, so the diameter of the expanded pipe should not change too much, or the pipe diameter will be gradually enlarged after multiple treatments. [0003] In the process of pipe expansion, there is a special problem that needs to be paid attention to. The conical head or top pressure screw of pipe expansion needs to be set concentrically with the metal pipe, so as to ensure the quality of pipe expansion. The installation of the pipe expander in the prior art does not handle the concentricity in place, which leads to errors during installation, which ultimately affects the quality of the pipe expansion. SUMMARY OF THE INVENTION [0004] The...
