Embodiment Construction
[0018] The present invention will be further described below in conjunction with drawings and embodiments.
[0019] The method of pressing the arc-shaped surface of square and circular joints by using a plate rolling machine. The plate rolling machine includes an upper roller 1 and two lower rollers 2. The connecting line between the centers of the upper roller 1 and the two lower rollers 2 forms a triangle. It is characterized in that , the specific steps of pressing the arc-shaped surface of the square and circle are as follows:
[0020] 1) Make the sheet material into a tire material for pressing the arc-shaped surface of the square circle;
[0021] 2) Place the tire material horizontally between the upper roller 1 and the two lower rollers 2, control the upper roller 1 to squeeze downward, press the tire material into an arc shape, and complete the rough process;
[0022] 3) Lift the upper roller 1, take out the arc-shaped tire material, install the pressed angle steel 3 ...

Disclosed is a method for pressing an arc-shaped surface of a cylindrical joint by the aid of a plate rolling machine. The plate rolling machine comprises an upper roller (1) and two lower rollers (2), and central connecting lines of the upper roller (1) and the two lower rollers (2) are connected into a triangle. The specific steps of pressing the arc-shaped surface of the cylindrical joint include: 1) manufacturing a mould material; 2) performing a roughing procedure; 3) performing fine adjustment for the mould material and turning to a step 4; and 4) comparing the mould material with the arc-shaped surface of a standard cylindrical joint. A worker only needs to control the position of the mould material in the whole process, so that the labor intensity of the worker is remarkably reduced, and production efficiency is improved. The arc-shaped surface of the cylindrical joint is pressed by the plate rolling machine, and the pressing position of the mould material and pressing displacement of the upper roller are approximately controlled, so that the finished shape of the arc-shaped surface of the cylindrical joint can be realized, and machining precision is improved.
Description
technical field [0001] The invention relates to a method for making a square-circle pitch, in particular to a method for making a square-round pitch with a plate rolling machine. Background technique [0002] In electric power construction, it is often necessary to process the square and round arc surface. The traditional square and circle arc surface processing method is as follows: the staff uses a hammer to bend the tire material, and hammers the tire material into a square and circle arc surface. Its shortcoming is: this method needs the staff to hammer the tire material for a long time, labor intensity is high and work efficiency is low, and when the wall plate thickness of square and round joints is greater than or equal to 8mm, the artificial hammering method is difficult to realize. Contents of the invention [0003] The object of the present invention is to provide a method for pressing the arc-shaped surface of square and round joints by means of a plate rolling ...
