Abstract
The utility model discloses a milling mechanism of a special miller for a tube plate partition. The milling mechanism comprises a fixed frame, a small belt pulley, a large belt pulley, a triangle belt and an adjustable-speed motor, wherein the large belt pulley is fixedly connected with a spindle, and a three-jaw chuck and a milling cutter are arranged at the lower end of the spindle. After the special miller for slot machining of the tube plate partition is manufactured, three partition slots of three tube plates with nominal diameters of DN 800 mm, DN 1,200 mm and DN 1,800 mm are selected for trial machining, the operation status and workpiece machining quality of the miller are evaluated, and the workpiece machining quality, precision and surface roughness can meet requirements of a drawing.
Description
Technical field
The utility model relates to milling machine field, specifically belongs to the milling mechanism of tube sheet dividing plate 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 milling mechanism of tube sheet dividing plate 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, operation conditions to 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:
The milling mechanism of tube sheet dividing plate production miller, 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 fixed mount is fixedly connected with middle carriage.
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), operation conditions to 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, to enterprise reduce production costs shorten the construction period, the equipment of assurance deliver goods on schedule improve goodwill play great role.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, the milling mechanism of tube sheet dividing plate production miller, includes fixed mount 1, small belt pulley 2, big belt pulley 3, V belt 4, buncher 5, and big belt pulley 3 is fixedly connected with main shaft 6, main shaft 6 lower ends are provided with scroll chuck 7, milling cutter 8, and fixed mount is fixedly connected with middle carriage.
