Description

Bus holding tooling

Technical field

The utility model relates to a kind of bus holding toolings.

Background technique

Existing concentration bus duct forms intensive bus in order to improve insulation performance, mostly by way of casting Slot.Chinese patent as Authorization Notice No. is CN203596578U, authorized announcement date is 2014.05.14 discloses a kind of casting Type bus duct, the casting type bus duct include a plurality of parallel conductor and the insulating layer that is wrapped in outside each conductor, and insulating layer is by exhausted Edge material is poured to be formed, and in casting, each conductor needs to fix in advance by conductor mounting bracket, so that between each conductor Every meeting insulating requirements.But above-mentioned conductor mounting bracket is arranged inside bus duct, is used only once, improves into This；Conductor mounting bracket needs to install multiple, and needs diaphragm plate to form bus duct, reduces production efficiency.Fluid technology at The insulating materials that type bus duct uses is powdery, is not needed using diaphragm plate, convenient formation.

Utility model content

The purpose of this utility model is to provide a kind of to form concentration bus duct so that intensive female by fluid technology The bus holding tooling of operation range is kept between the adjacent bus of wire casing.

To achieve the above object, the technical solution of the utility model bus holding tooling is:

Bus holding tooling includes being arranged in pairs for clamping the bracket of each end of bus bars, and the bracket is equipped with for each The end of bus inserts so as to keep the mounting groove of operation range between adjacent bus, and the mounting groove, which has, is used to support each mother The supporting surface of the end of line.

The notch of the mounting groove constitutes the supporting surface towards horizontal direction, one of cell wall of mounting groove.Cell wall It is larger with the stress surface of bus, avoid the deformation of bus.

The groove depth of the mounting groove is less than or equal to the width of each bus.The end of each bus is clamped in peace convenient for cover board In tankage.

The bus holding tooling further includes for the fixing piece in mounting groove that the end of each bus is fixedly clamped.Gu Determining part can preferably be fixed on the end of each bus in mounting groove.

The fixing piece is the cover board for being sealed on mounting groove notch, the cover board and bracket releasable connection.Covering plate structure letter It is single, it is easy to process.

The cover board and bracket pass through bolt releasable connection.Convenient disassembly improves work efficiency.

The beneficial effects of the utility model are: being assemblied in by the both ends of the mounting groove and each bus of two pairs of brackets Together, so that bus is being fluidized gap size when being able to maintain work when molding, guarantee the insulation performance between each bus, be convenient for The integrated molding of bus and insulating materials avoids interval too small, and the insulation performance of molding concentration bus duct is poor, is spaced Greatly, molding concentration bus duct size is larger, while the interval between two neighboring bus can be guaranteed along the length of bus Direction is all the same.

Specific embodiment

The embodiments of the present invention is described further with reference to the accompanying drawing.

The specific embodiment of the bus holding tooling of the utility model, as shown in Figures 1 to 5, bus holding tooling includes What is be arranged in pairs is used to clamp the bracket 2 of each 1 end of bus, and bracket 2 is equipped with the end inserting for each bus 1 so that adjacent mother The mounting groove 21 of operation range is kept between line 1, mounting groove 21 has the supporting surface for the end for being used to support each bus 1.Such as Fig. 3 With shown in Fig. 4, in the present embodiment, for the notch of mounting groove 21 towards horizontal direction, one of cell wall of mounting groove 21 constitutes institute State supporting surface, the stress surface of cell wall and bus is larger, avoids the deformation of bus.In other embodiments, the notch court of mounting groove Bus is supported by slot bottom to vertical direction.Bus holding tooling further includes solid for clamping the end of each bus 1 The cover board 4 being scheduled in mounting groove 21, cover board 4 constitute fixing piece, and cover board 4 is sealed on the notch of mounting groove 21, can be better The end of each bus is fixed in mounting groove, furthermore covering plate structure is simple, easy to process.In other embodiments, two branch The opposite side of frame is hinged with fixed link, and the end of each bus is clamped in mounting groove by fixed link；Or bus holding work Dress does not include cover board.As shown in Figure 2 and Figure 4, in the present embodiment, bracket 2 is equipped with fixation hole 22, cover board 4 and bracket 2 and passes through admittedly Determine hole 22 and releasable connection is realized in bolt cooperation, convenient disassembly improves work efficiency.In other embodiments, cover board 4 and branch Frame 2 is hinged on bracket by snap releasable connection or cover board.

As shown in Figure 1 and Figure 5, the concentration bus duct of the bus holding tooling of the use in the present embodiment fluidizes molding side Method: 1) first polishing to bus 1, dedusting, cleaning, and the position that 1 end of bus is not required to fluidisation is wrapped up using High temperature-resistanadhesive adhesive tape, Bus 1 is placed on two brackets 2 again, cover board 4 and 2 use of bracket are bolted fastening, the position of fixed bus 1, branch Frame 2 can make the interval between bus 1 meet the requirements.Then bus 1 and bracket 2 are put into togerther in baking oven and are preheated, preheating temperature Degree is 180 ~ 190 DEG C, and wherein specification is 40min in the preheating time of 80 × 8mm and the bus of dimensions above, specification 80 × The preheating time of 6mm and bus below is 30min.2) 5min starts fluid-bed before preheating is completed, and connection ventilation adjusts gas Valve takes out bus 1 after the completion of preheating, and bus 1 is put into fluid-bed and is fluidized, and makes adjacent two by blowing into cabinet Powdered insulating materials is wrapped up in powder filler shape insulating materials in a interval of bus 1, the periphery of each bus 1.Etc. 3) buses 1 are complete After powdered insulating materials cladding, bus 1 and bracket 2 are taken out from the cabinet for being contained with powdered insulating materials, and again It is put into baking oven, makes to be adhered to the powdered insulating materials curing molding on bus 1 on bus 1, solidification temperature is 180 ~ 190 DEG C, curing time is 30 ~ 40min, and powdered insulating materials curing molding in adjacent two buses 1 interval is spacer insulator Part is package insulated part in each 1 periphery curing molding of bus.4) step 2 and step 3) are repeated in twice, and last Primary curing time is 45 ~ 55min, and final bus 1 is integrally molded so as slot core with spacer insulator part and package insulated part, Spacer insulator part and package insulated part constitute insulating layer 3, remove bracket 2, cover board 4 and high-temperature plastic after forming slot core Band.Be assembled together by the both ends of the mounting groove and each bus of two pairs of brackets, make bus in moulding by casting or It is able to maintain the gap size when work when fluidisation molding, guarantees the insulation performance between each bus, is convenient for bus and insulation material The integrated molding of material avoids interval too small, and the insulation performance of molding concentration bus duct is poor, and interval is excessive, molding intensive Type bus duct size is larger, while can guarantee that the interval between two neighboring bus is all the same along the length direction of bus.
