Abstract
The utility model discloses a special miller for machining a separation plate of a tube plate. The special miller comprises a bracket, wherein a workbench is mounted on the bracket; a guide rail and a screw rod are mounted at the upper end of the bracket; the guide rail is matched with a horizontal walking mechanism and a vertical height adjusting mechanism; the screw rod is spirally matched with the horizontal walking mechanism; a hand wheel is mounted at the other end of the screw rod; a milling mechanism is mounted on the vertical height adjusting mechanism; the horizontal walking mechanism is jacked at the vertical height adjusting mechanism. After the special miller for machining separation plate grooves of the tube plate is manufactured, the three separation plate grooves of the three tube plates with nominal diameters (DN800mm, DN1200mm and DN1800mm) are selected for test machining; the operation states of the miller and the machining quality of workpieces can be evaluated; the drawing requirements on the machining quality, the precision and the surface roughness of the workpieces can be met.
Description
Technical field
The utility model relates to milling machine field, specifically belongs to tube sheet dividing plate processing production miller.
Background technology
Heat exchanger is the capital equipment of Chemical Manufacture, and heat exchanger is an important component part during pressure vessel is manufactured.In heat exchanger, the processing of double-shell side, two-tube-pass and multi-tube pass heat exchanger tube sheet septalium is an important manufacturing procedure, and dimensional tolerance, form and position tolerance and surface roughness are all had higher requirements.Along with the scale of Chemical Manufacture in recent years constantly expands, the size of heat exchanger is also continuing to increase, for large scale heat exchanger septalium, processing needs large-scale metal-planing machine or planer-type milling machine, the procurement price of this large-sized processing equipment is generally at hundreds of thousands or up to a million, general middle-size and small-size production of pressure container enterprise cannot bear, and utilization rate is not high.The way of cooperation processing is generally taked in the processing that runs into this type of tube sheet septalium, but the cooperation processing time is long, and processing charges is high, adds round transport, causes construction delay, and cost increases, and affects the economic benefit of enterprise.
Utility model content
The purpose of this utility model is to provide a kind of tube sheet dividing plate processing production miller, after the manufacture of tube sheet septalium processing production miller completes, select three septaliums of three tube sheets of nominal diameter (DN800mm, DN1200mm, DN1800mm) to try processing, the operation conditions of this milling machine and workpiece crudy are evaluated, and workpiece crudy, precision, surface roughness all can all reach the requirement of drawing.
The technical solution of the utility model is as follows:
Tube sheet dividing plate processing production miller, include support, workbench is installed on support, support upper end is provided with guide rail, leading screw, on guide rail, be combined with horizontal running mechanism, vertical height guiding mechanism, leading screw coordinates with horizontal running mechanism spiral, and the other end of leading screw is provided with handwheel, on vertical height guiding mechanism, milling mechanism is installed, horizontal running mechanism overhead is in described vertical height guiding mechanism; Described milling mechanism includes fixed mount, small belt pulley, big belt pulley, V belt, buncher, and big belt pulley is fixedly connected with main shaft, and main shaft lower end is provided with scroll chuck, milling cutter; Described vertical height guiding mechanism includes height regulating rod, middle carriage, and height regulating rod coordinates with middle carriage spiral, middle carriage and the fixed installation of described fixed mount.
Power switch, horizontal vertical motion switch are installed on described guide rail.
After the manufacture of the utility model tube sheet septalium processing production miller completes, by departments such as technology, production, check, equipment, metalworkings, form checking group, this milling machine is processed by the examination of workpiece, select nominal diameter (three septaliums of DN800mm, DN1200mm, tri-tube sheets of DN1800mm try processing), the operation conditions of this milling machine and workpiece crudy are evaluated, workpiece crudy, precision, surface roughness all can all reach the requirement of drawing, and beneficial effect is as follows:
1 whole milling machine operation conditions is normal, good, noise is low, it is little, vertical to shake and horizontal feed adjustment nimbly and freely.
The 2 septalium degree of depth that process, width, linearity and machined surface roughness all reach pattern requirement.
3 because this tube sheet septalium processing production miller is in manufacture process, utilize waste and old machine tool component and leftover pieces, whole processing and manufacturing completes by the worker of our unit as far as possible, makes manufacturing expense very low, total is less than 20,000 yuan, for enterprise saves a large amount of equipment purchase funds.
4 through the examination processing to three tube sheets, proves that this milling machine operation conditions is good, and workpiece crudy reaches pattern requirement.
5 have solved a great problem of large scale heat exchanger tube sheet septalium processing, large scale tube sheet septalium processing from now on no longer needs external coordination, for enterprise saves a large amount of cooperation processings and round transport expense, enterprise is reduced production costs and shortens the construction period, and the equipment of assurance delivers goods on schedule and improves goodwill and play great role.
