Cold bending (forming) machine is a new type of tunnel support steel arch processing equipment. It is composed of base, mechanical drive, cold bending system, hydraulic system, electrical control system and auxiliary system.
Safe use of cold bending (forming) machine:
Cold bending (forming) machine is a new type of tunnel support steel arch processing equipment, is to adapt to the surrounding rock geological poor construction section and the production of special processing equipment, with surrounding rock changes and random changes. Before using the cold bending machine there are a lot of problems need to pay attention to, the following take you to understand:
1. To choose a flat table and put the machine firmly, you can pull the foot of the machine case to make the machine panel easy to observe. Insert the plug of the hand-held sensor head into the socket on the panel and tighten it, paying attention to locating the gap.
2. Plug one end of the power cord into the socket on the back plate of the chassis and the other end into the power supply socket. Please be sure to use single-phase three-wire system power.
3. Turn on the "POWER SW." on the back panel of the chassis and press the "POWER switch" button. Press and hold the "SETTING BUTTON" BUTTON to set the appropriate value, usually between 0.5 and 2.0 seconds. Third put container induction head cover above, click the start button on the handle, the red indicator HEATING (HEATING), said it was heated, the sensing head don't move, "HEATING (HEATING)" red light out and then remove the induction head, finally, "preparation (WARM UP)" the green light is lit or internal buzzer short sound of "du" tip and then can go to the next container sealing operation. Check the sealing quality and adjust the "SETTING BUTTON" BUTTON according to different materials, diameter of the container and production efficiency to make the sealing quality be the best.
Maintenance of cold bending (forming) machine:
The fixed displacement of the cold forming machine, the shortening or swelling displacement between the end of the cold forming machine and the start support is only a small part of the data shown in the table, usually from the middle to the initial direction of each end of the cold forming machine. Each end displacement is only shortened or expanded by a large half together with the steel purlin thickness to be able to override the screw's selfdrilling ability. Cold bending machines currently supply screws with plastic head, stainless steel cover or coated with special durable protection, other, self tapping screw selection. When the selection of fixing screws should be according to the structure of the use of life to choose the fixing parts, cold forming machine in addition to the hidden button fixing screws, other screws with waterproof washer, and alignment plate and special wind pressure are equipped with a corresponding common washer and some details of the treatment is more important. About roofing should be used in the roof and eaves of the cold bending machine will stop the corresponding mission, the device is easier to grasp, its intention to more effectively prevent rain into the roof.
Materials and specifications of cold bending machine:
Each roll color plate should be less than 5T, the outer diameter is not greater than 1300mm, the diameter of the coil is 600mm or 500mm. Core material is made of EPS board or rock wool board, the volume density of EPS is 10 ~ 20Kg/m3, the length of a single piece should be larger than 3m, the board surface should be flat, its width is: socket board 1150mm, H plate 1200mm double female plate 1150mm cap corrugated board 950mm lap corrugated board 970mm. The thickness of EPS shall not be less than 50mm. Glue: the adhesive strength of PU adhesive should be greater than 10N/cm2, and there should be no impurities in the glue. At room temperature, the foaming time should be 20-40 seconds, the curing time should be 50-70 seconds, and the oxygen index should be greater than 30. The glue is divided into two groups, A and B, and the proportion of the two groups is A: B= 1:1.25
Cold bending (forming) machine operating environment requirements:
1. The ground of the workplace should be flat and clean, and there should be no pits, trenches, holes, etc. No water or grease.
2. Necessary space and passage shall be left around the cold bending machine, and the spacing shall meet the corresponding minimum safety distance requirements.
(1) when there is no working ground between the side of the machine tool and the wall or column, the spacing is 400-500mm;
(2) when there is a working place; Spacing is 1000-1200 mm; When there is no working ground between the machine tools, the spacing is 800mm;
(3) when there is a working ground on one side of the cold bending machine and pedestrians pass through it regularly, the spacing is 1200mm; When both sides of the machine tool have working ground, the spacing between the machine tools is 1500mm;
(4) when both sides of the machine tool have working places and pedestrians pass by, the spacing is 1800mm.
