Problems solved by technology

[0002] In the design of the tunnel grid arch frame, more "8" bars are used as the inner skeleton support of the grid arch frame. The eight-shaped rib is a three-dimensional structure, and its decomposition unit is also a three-dimensional structure. The bending process of the manual bending machine cannot meet the bending accuracy, and the size is not uniform. It is more difficult to weld the formed "8" rib and the main grid rib. It is easy to cause the main reinforcement to fail to maintain a uniform plane, thus reducing the clearance inside the arch

Embodiment Construction

[0022] The "8" rib processing machine in this embodiment includes a horizontal processing unit and a vertical processing unit.

[0023] see figure 1 , figure 2 and image 3 , the horizontal processing unit is used to squeeze the horizontally placed rectangular steel frame 1 in the middle of the left and right frames until the left and right frames are closed in the middle, and weld the left and right frames at the closed position of the middle to form a horizontal "8" Word frame 2; the structure of the horizontal processing unit is set as follows: on the horizontal workbench, a pair of limit stoppers 3 are fixed according to the width and length of the rectangular steel bar frame 1, and the rectangular steel bar frame 1 is set on a pair of limit stoppers 3 On the left and right sides of the rectangular steel bar frame 1, a pair of horizontal "8" molds 4 are arranged opposite to each other in the shape of "8", and the horizontal "8" molds 4 can slide left and right under the...

Abstract

The invention discloses an 8-shaped rib processing machine which is characterized by comprising a horizontal processing unit and a vertical processing unit, wherein the horizontal processing unit is used for extruding a horizontally-placed rectangular steel bar frame between a left side frame and a right side frame in opposite directions until the left side frame and the right side frame are folded in the middle and welding the left side frame and the right side frame at the middle folded position to form a horizontal 8-shaped frame; the vertical processing unit is used for extruding the horizontal 8-shaped frame downwards at the middle folded position until the horizontal 8-shaped frame is in preset bending on a vertical face. The 8-shaped rib processing machine is reasonable in structural design, high in processing precision, low in construction cost and high in production efficiency.

Description

technical field [0001] The invention relates to a processing machine for preparing tunnel grid arches. Background technique [0002] In the design of the tunnel grid arch frame, more "8" bars are used as the inner skeleton support of the grid arch frame. The eight-shaped rib is a three-dimensional structure, and its decomposition unit is also a three-dimensional structure. The bending process of the manual bending machine cannot meet the bending accuracy, and the size is not uniform. It is more difficult to weld the formed "8" rib and the main grid rib. It is easy to cause the main reinforcement to fail to maintain a uniform plane, thus reducing the clearance inside the arch. Contents of the invention [0003] In order to avoid the disadvantages of the above-mentioned prior art, the present invention provides an "8" rib processing machine. By using a mold to determine the bending size of the "8" rib, the processing accuracy and the "8" rib are improved. Uniformity of pro...
