From the perspective of space frame structure, each part specification should consider the following relevance: the specifications of the inner gasket are not lower than the outer diameter of the high-strength bolt nut. The outer gasket specification should not be lower than top of the cone head outer diameter.
Cone head machining: After the cone head is forged and shaped, a milling machine is used to process the stairs with the cone head and the inner cavity of the rod tube, the plan view of the small diameter end of the cone head and the welding seam, and the flatness of both sides of the cone head is controlled at 0.5mm. After face milling, the center line of the threaded hole processing line is drawn on the scribing platform, and the conical head assembly precise positioning and clamping inspection positioning points are also depicted. The production and processing of the wire hole is made by a horizontal machining center.
How to connect the ball cone head of the grid bolt and the sealing plate:
Take the sample and eject it at will. After the high temperature, weld the sealing plate or cone on the open end for each section of the end. Prepare the experimental sealing plate and cone in advance. The standard appearance must not have cracks, coarse crystals and air oxide skin.
The welding root of the sponge head of the penis should be provided with a compressive strength test. The output test point index should meet the requirements and the most suitable parameters should be selected. With the same specification model component 300 roots as a batch, each time take 3 roots as a group of arbitrary sampling inspection, less than 300 roots still according to a batch.
How to connect the cone-head screws of the grid:
Cone head is a spare part used in the bolt ball space frame structure. It is welded on the top of the steel pipe. The extruder screw of the high-strength bolt is screwed into the bolt ball through the round hole at the bottom end. The nut is inside the cone head. The effect of the “sealing plate” is the same. The steel pipe diameter is smaller than that of the “sealing plate”. When the steel pipe diameter is large, in order to prevent collisions between the steel pipes on the same bolt ball, the “cone” is selected.
