Description
Technical Field
The invention relates to the field of manufacturing of power transmission equipment, in particular to a bus duct production line.
Background
The prior conventional intensive bus duct has the structural characteristics that: the dense bus duct consists of a shell, a phase bus, a polyester film, an insulating partition board, an insulating clamping block, a shell fastener, a connector fastener and the like, and the surface of the bus is coated by the polyester film; the buses are tightly arranged and clamped according to the sequence of L1, L2, L3 and N and are assembled in a bus duct shell to form a sandwich structure. The existing intensive bus duct is formed by fastening a cover plate and a side plate which are formed by fastening a shell (cover plate and side plate), a conductor (copper bar or aluminum bar), an insulating material and a fastening piece. Most bus ducts in the prior art are fastened and shaped by riveting technology, and 2 types of bus ducts are automatically and manually riveted. The method is generally adopted, after the bus is preassembled, the bus is tightly pressed from two or four direction cylinders on a fixed tool, and the bus is riveted point by point according to the process positioning requirement of riveting points through a rivet or a rivetless riveting gun. The riveting process is long in time consumption, low in efficiency and multiple in riveting points, has no good quality control means for the riveting strength of each point, and is easy to cause blank riveting (no rivet), missed riveting (the riveted point is not riveted), multiple riveting (the riveted point is not riveted) and the like, so that the consistency of the bus structure is difficult to be ensured. The bus duct is also provided with a fastening mode of a bus, and the fastening is realized by combining the conductor size and the insulating material size through the fastening process of the preassembly component without riveting during the structural design of the bus. This process is very efficient, but suffers from the following drawbacks:
1. after various parts of the bus duct are assembled together in design, whether the optimal clearance requirement is achieved through compaction or not;
2. the reserved gap is too small, so that the bus cannot be buckled, and more air exists in the bus duct which is too large, so that conduction and heat conduction are not facilitated, and the bus temperature rise cannot reach the expected index;
3. after most buckling modes have buckling points for buckling, a small range of rebound occurs when the compression cylinder is released, and a gap is generated;
4. the size difference of each batch of parts supply has no compensation means, and the size difference can be converted into the performance difference of each batch of buses.
As such, bus ducts have been developed specifically for the above-mentioned deficiencies, and correspondingly, in order to improve production efficiency and product quality, the bus duct production line of the present application has been developed to solve the above-mentioned process difficulties.
