Description

The special multi spindle drilling machine of aluminum electrolytic cell riser bus bar group " 4+6 " axle combined type

Technical field

The utility model belongs to non-ferrous metals processing manufacturing field, applied to large-sized prebaked cell for aluminum-reduction fabrication and installation The Drilling operation of riser bus bar group in engineering, it is special more particularly to a kind of aluminum electrolytic cell riser bus bar group " 4+6 " axle combined type Use multi spindle drilling machine.

Background technology

Electrolytic aluminium factory typically possesses hundreds prebaked cell for aluminum-reduction, the electricity input side one of large-sized prebaked cell for aluminum-reduction As 6 ~ 7 groups of riser bus bar groups are installed.Every group of riser bus bar includes 2 riser bus bars（A types and Type B, material：Aluminium）, 2 clamping plates Bus（A types and Type B, material：Aluminium）With 2 short-circuit busbars（Material：Aluminium）, need to process bolt connecting hole on this 6 buses, and They are fitted together by connecting bolt, is then fitted into the electricity input side of aluminium cell, to carry super large Faradaic current Pass through.

Below with the riser bus bar of most ripe, the most widely used 500kA large-sized prebaked cell for aluminum-reduction of current techniques It is further described exemplified by group.

The riser bus bar size of the type electrolytic cell is（Unit：mm）：2935 × 500 × 230, φ 55 × 4 is designed with above One group of bolt connecting hole, one group of 38 × 6 bolt connecting holes of φ；Clamping plate bus bar sizes are（Unit：mm）：2000 × 500 × 230, One group of 38 × 6 bolt connecting holes of φ are designed with above；Short-circuit busbar size is（Unit：mm）：500 × 450 × 220, set above In respect of one group of 55 × 4 bolt connecting holes of φ.The bolt connecting holes of φ 55 × 4 on riser bus bar and the φ 55 × 4 on short-circuit busbar The hole position of bolt connecting hole is the bolt connecting holes of φ 38 × 6 on riser bus bar and the φ 38 on clamping plate bus corresponding to difference The hole position of × 6 bolt connecting holes is corresponding to difference.

In large-sized prebaked cell for aluminum-reduction fabrication and installation engineering, the Drilling operation of riser bus bar group is one very heavy Will and the very huge work of quantities, this multi spindle drilling machine be exactly female exclusively for the column for drilling through large-sized prebaked cell for aluminum-reduction This two groups of bolt connecting holes in line group and design.

At present in the case of the overwhelming majority, still using Z3050 and the radial drilling machine of above specification to all holes on bus Position is drilled through one by one.The defects of this method is：First, device to hole（Drill bit aligns design hole position）Intricate operation, workpiece add up and down Work station is often（One workpiece for having two kinds of specification hole positions needs to replace between different drilling machine processing stations, also or Person needs constantly to change the drill bit of different size on same radial drilling machine）, crane gear time length is taken, is not only produced Efficiency is extremely low, and hole position precision is low, Form and position error is high, and directly influences follow-up installment work（Often there is work Connecting bolt can not pass through the phenomenon of link bolt hole between part）；2nd, the structure of radial drilling machine is comparatively more complicated, Along with construction site condition is simple and crude, not in place to the Rough operation of equipment, maintaining so that radial drilling machine is using one section Fault rate drastically rises after time, and not only maintenance cost increases（Generally it is required for asking specialized maintenance personnel to march into the arena dimension Repair）, and have a strong impact on project progress.More radial drilling machines on Active workings be present（Typically all more than 4）Make simultaneously In the case of industry, the maintenance to radial drilling machine has become the normality in work daily；3rd, must because production efficiency is low More rigs must be used, which to work simultaneously, could meet the requirement of construction speed so that equipment investment is high, and equipment is to operation The occupancy in place is big, and operating personnel is more, and cost of labor is very high.

Under few partial picture, the practical application of 4 axles brill can be seen, but device is excessively simple and crude, belong to more it is original its Secondary transformation on its Waste machine tool, not only machining accuracy is relatively low, and an only fixed processing stations, up to the present The single-piece work of short-circuit busbar is also only suitable only for, riser bus bar and clamping plate bus still need to be added using radial drilling machine Work, the change of the situation low to production efficiency are extremely limited.

Practical application of the six axle drilling machines in electrolytic cell pillar bus processing is also seen in the prior art, but it is same without energy When oppose element cylinder（A types, Type B）, clamping plate bus（A types, Type B）And short-circuit busbar carries out the multi-drill of multi-spindle drilling processing Bed, and existing six axles drilling machine can not be convenient for changing gear-box, it is impossible to adapt to the drilling of different size electrolytic cell pillar bus group Processing, poor universality, and existing six axles drilling machine does not have supporting feed mechanism, it is impossible to evade device to hole process, hole position precision It can not effectively improve, the labor intensity of operator is also larger, still more to the occupancy of crane gear in process.
