Description
Technical field
The utility model belongs to oil-filled transformer magnetic screen manufacturing technology field, the general closed assembly mould of particularly a kind of L shaped magnetic screen.
Background technology
Continuous development along with transformer technology, the L shaped preferably structure magnetic screen of more and more employing shielded coil leakage field effect in the power transformer product design of 220KV and above electric pressure, but when designing with the L shaped magnetic screen of electric pressure and different electric pressures, the size of every magnetic screen, the pitch-row of installing hole, thin and thick is all different, and specification is wide in variety, every kind of specification quantity is many, therefore every product need be manufactured special-purpose closed assembly die worker dress, the magnetic screen of every kind of specification all will be prepared many covers or tens molds, it is big that mould is manufactured expense, cycle is long, and the frock utilance is low, can not be general.
The utility model content
In order to overcome the above problems, the utility model provides a kind of L shaped magnetic screen general closed assembly mould, closed assembly mould simple in structure, easy to operate, that a mould is general.
The technical solution adopted in the utility model is: the general closed assembly mould of a kind of L shaped magnetic screen, comprise lower mold body, lower platen, side guide and connecting rod, and lower mold body is by baffle plate and counterdie side plate are formed down; Following baffle plate and lower platen are provided with many row's fabrication holes, and counterdie side plate and side guide are provided with single strip hole; Fix by connecting rod between following baffle plate, the neat face of L shaped magnetic screen and the lower platen; The counterdie side plate, L shaped magnetic screen is domatic and side guide is fixed by connecting rod.By setting the technology round, no matter the thickness and the width of L shaped magnetic screen can reach the fixing purpose of closed assembly.L shaped magnetic screen is by neat face and domatic the composition, one side that the end of L shaped magnetic screen is being referred to as of tilting is domatic, one side the end of L shaped magnetic screen is the neat neat face that is referred to as.The neat face of L shaped magnetic screen is provided with circular hole, the domatic strip hole that is provided with of L shaped magnetic screen.
Described connecting rod is a bolt, and the polished rod height H equals L shaped magnetic screen thickness, lower mold body thickness and 1/2 lower platen thickness three sum; For preventing closed assembly and pressing against fixedly the time and hinder magnetic screen, be with the protection nylon jacket, be tightened with nut.Following baffle plate in the lower mold body, counterdie side plate and lower platen, side guide thickness are identical;
A kind of optimal way: arrange the horizontal spacing 30mm of fabrication hole, longitudinal pitch 40mm more; The length 92mm of strip hole in the single strip hole, width 24mm.
The implementation of the utility model purpose is, on following baffle plate that laminates L shaped magnetic screen and lower platen, be provided with many row's fabrication holes, counterdie side plate and side guide are provided with single strip hole, L shaped magnetic screen utilizes the fabrication hole on the closed assembly mould to carry out handle and sets the position, product position of mounting hole and size design arbitrarily according to the structure needs, and be unrestricted.
1) magnetic screen that the overlappable 10mm of mold design is thick, 15mm is thick, 20mm is thick, it is general to reach a mould.
2) universal mold of several length of mold design, the closed assembly of suitable all lengths magnetic screen.
3) when designing, increases by the magnetic screen drawing fabrication hole, the corresponding design of fabrication hole with the closed assembly mould, and fabrication hole separates design with the product hole, and the product hole can reasonably be designed.
Mold design is a loose structure, at lower mould base plate and lower platen horizontal stroke, vertically open many row's fabrication holes, remove inboard first row of baffle plate and second row's fabrication hole spacing down, minimum range according to the design of magnetic screen thickness range, guaranteeing that different-thickness magnetic screen root can be well secured, apart from 30mm technology round, vertically the standard width of a room in an old-style house is apart from 40mm technology round at lower mould base plate and the horizontal standard width of a room in an old-style house of lower platen for all the other, platoon leader's cylindrical void laterally only left by side guide, and uses the connecting rod fastening means.
The flow process that the utility model uses, the following baffle plate that at first will be provided with loose structure is set level, and connecting rod passes down the hole of baffle plate, the gluing stack, brush coating of monolithic passes connecting rod successively with the brush coating face then and stacks down on the baffle plate; Behind the closed assembly, install and fix lower platen earlier, the fixation side pressing plate closes the tight card of L shaped magnetic screen and lower mold body and pressing plate again, orthopedic meet the drawing angle and require after, right fed to boiler solidifies.
The beneficial effects of the utility model: 1. mass effect: the closed assembly quality obviously improves, and can guarantee product quality well.2. raise the efficiency: simple to operate, convenient, closed assembly is enhanced productivity fast.3 applicabilities: one module multiple usages, can use different-thickness, dimensions magnetic screen closed assembly, reduce expenses, and be beneficial to the operation field management.
