Asphalt mixing plant flat bag skeleton Asphalt mixing plant flat bag cage skeleton bag cage bone frame diamond bag skeleton elliptical bag skeleton bag skeleton perpendicularity tolerance inspection, place the end face of the filter bag frame mouth on a horizontal flat plate, make it perpendicular to the horizontal plane, and hang a hanging line heavy hammer on its edge. Use a ruler to measure the distance between the upper and lower edges of the frame and the hanging line, and the difference should comply with the provisions of 4.9.
Processing technology of flat cloth bag skeleton bag cage bone frame cage body for asphalt mixing plant:
Flat and wavy bag cages for asphalt stations can be completed with 8, 10, and 12 bars on one machine
Straightness and perpendicularity preservation of flat bag cages for asphalt stations
The advantages of using point convex welding for the support of the flat cloth bag skeleton bag cage frame in the asphalt mixing plant are:
1. Easy to maintain verticality: Accurate size positioning, fast welding speed, and the ability to weld multiple welding points simultaneously in one welding cycle.
2. Energy saving: Due to the high current density at the convex point, welding can be carried out with a smaller current, and smaller fusion nuclei can be reliably formed.
3. High welding strength: The convex welding position is accurate and the size is consistent, which makes the strength of the welding head more uniform and consistent.
4. Easy to operate: capable of welding workpieces of different structures.
5. Small surface burrs: Due to the use of large planar electrodes and the placement of protrusions on one workpiece, it can greatly reduce the indentation on the exposed surface of another workpiece.
Verticality and straightness preservation of flat bag cages for asphalt stations
Verticality refers to the perpendicularity between the central axis of the bag cage and the installation reference surface of the bag cage support.
1) Several key points related to the verticality of the bag cage:
The verticality of the bag cage refers to the verticality between the upper support plane and the axis of the bag cage
The key is to adjust the mutual position of the bag cage bracket and the welding machine positioning reference to ensure that the upper support plane is perpendicular to the bag cage axis.
Experimental results have shown that the asphalt station bag cage adopts a point convex welding support structure, which is easier to maintain verticality and facilitate processing.
2) Several key points related to the straightness of the flat cloth bag skeleton bag cage frame in the asphalt mixing plant:
The steel bars must be straightened
The size of the ring reinforcement must match the mold core, and should not be too loose or too tight
Adjust the welding machine and track according to the requirements of the bag cage, and adjust the electrical level on time according to the operation manual
