[0002] Round steel pipe is a commonly used section steel, which is widely used in various fields. The more common ones are construction and industrial fields. At the same time, many household products also use round steel pipes as the skeleton of tables and chairs. In actual use, consider For strength or shape matching problems, this type of steel pipe must be bent. Several issues need to be considered when bending round pipes: 1. Accurate positioning of the bending point. If the bending point deviates greatly, it is easy to cause The proble...

Embodiment Construction

[0014] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0015] Such as Figure 1 to Figure 4 As shown, a positioning mechanism of a round pipe bending device includes a fixed worktable 1 and a rotatable rotating worktable 2, and a freely rotating rotating round table 3 is arranged between the fixed workbench and the rotating worktable. In this embodiment, The rotating table rotates around the rotating table as the center. One end of the round pipe 4 is positioned on the fixed table, and the other end is fixed on the rotating table. The side wall of the rotating table is provided with an arc concave surface 31, and the outer wall of the round pipe is also an arc surface. , the circular arc surface is just accommodated in the circular arc concave surface. When the circular tube is actually positioned, the middle part of the circular tube fits in the circular arc concave surface of the side wall of the ro...

Abstract

The present invention discloses a positioning mechanism of a circular pipe bending device. The positioning mechanism comprises a stationary work table and a rotary work table capable of rotating; a freely rotating rotary circular bench is disposed between the stationary work table and the rotary work table; the circular pipe is positioned on the stationary work table; the circular pipe is bended in a rotation direction when the rotary work table rotates along a plane; the stationary work table is provided with a first clamping device for clamping the front portion of the circular pipe; the first clamping device comprises a first chuck and a driving device for driving the first chuck; the rotary work table is provided with a second clamping device for clamping the rear portion of the circular pipe; the second clamping device comprises a second chuck and another driving device for driving the second chuck; a positioning bench for positioning the circular pipe is disposed on the stationary work table; and the head bend of the positioning bench is provided with an L-shaped positioning strip. The positioning mechanism is accurate in positioning and good in clamping effect, and is not easy to loosen.

Description

technical field [0001] The invention relates to a positioning mechanism of a round pipe bending device. Background technique [0002] Round steel pipe is a commonly used section steel, which is widely used in various fields. The more common ones are construction and industrial fields. At the same time, many household products also use round steel pipes as the skeleton of tables and chairs. In actual use, consider For strength or shape matching problems, this type of steel pipe must be bent. Several issues need to be considered when bending round pipes: 1. Accurate positioning of the bending point. If the bending point deviates greatly, it is easy to cause The problem of large assembly errors or even inability to assemble late-stage products; 2. Springback phenomenon. Many round steel pipes are prone to springback after being bent. There are many stamping bendings. Stamping bending is to use the momentum to quickly bend. When the momentum disappears, the round steel pipe wil...
