Description

The mould of gradation compacting ultra-large type plate type heat exchanger plate
Technical field
The utility model relates to the compacting tool set of plate type heat exchanger plate, especially suppresses the mould of ultra-large type plate type heat exchanger plate about a kind of gradation.
Background technology
Plate type heat exchanger is as efficient, energy-conservation, compact heat-exchange apparatus, be applied in large quantities in the industrial production, Chinese large-sized chemical industry journey project had been on the increase in recent years, require to use the engineering project of large-scale, ultra-large type, complexity plate type heat exchanger more and more, therefore, the appearance and size of plate type heat exchanger plate also strengthens thereupon, and the die size of so suppressing board-like heat exchanger plate sheet is also increasing thereupon, and the hydraulic press tonnage of requirement also increases exponentially thereupon.
The structure of China's ultra-large type plate type heat exchanger plate shaping dies mainly is made up of guide pillar, guide pin bushing, upper bolster, upper mold core, die shoe, lower mold core and set bolt at present, core rod is fixed on the die holder with set bolt, under the pressure effect of hydraulic press, under the guiding of guide pin bushing and guide pillar, upper and lower die holder passes through upper and lower core rod fixed thereon to press forming of a plate.General 1.0m 2Needed effective pressure was 10000 tons when the plate of heat exchange area was shaped, and the hydraulic press effective pressure of domestic most of plate type heat exchanger manufacturing firm has only about the 6000-8000 ton, and the homemade hydraulic press technology that surpasses 20000 tons is immature.As suppress superhuge plate, and the mould of its punching press also strengthens accordingly, and the pressure ton of hydraulic test increases for needing equally thereupon.And choose the large-tonnage hydraulic test, certainly will increase cost of investment, and limit the extensive use of ultra-large type plate type heat exchanger thus.For under the situation of existing hydraulic test pressure tonnage deficiency, producing up-to-standard ultra-large type plate, adopt the technology of " changing greatly little, gradation calendering " or " one group of mould repeatedly prolongs pressure ", to replace the production technology of " mold uses a large-tonnage hydraulic press " calendaring molding.So, a mold that is about to former once calendaring molding is divided into the mould of some cover gradation compactings.The uniformity consistency of and ripple not overlapping, uninterrupted for the ripple that guarantees plate gradation calendaring molding, the linking section of forward and backward two molds must be provided with the positioning process benchmark of transition gradually.
The utility model content
Originally being the purpose of utility model, is to propose a kind of mould of suppressing ultra-large type plate type heat exchanger plate for being suitable for little tonnage hydraulic press compacting ultra-large type heat exchanger plate.The utility model is to adopt following technical scheme to realize: a kind of mould of gradation compacting ultra-large type plate type heat exchanger plate, comprise upper bolster, upper mold core, die shoe, lower mold core, it is characterized in that the inboard that the upper and lower core rod of compacting tool set for the first time is positioned at feed end is respectively equipped with technology punch insert and technology die plate insert, the both sides of upper mold core are provided with from the top of technology punch insert to the datum level sloping shape punch insert of transition convergence gradually; The upper mold core front end of compacting tool set is provided with the elasticity locating pad for the second time; The upper mold core front end is provided with downward translot of notch or break slot, and the elasticity locating pad is arranged in the groove, and the elasticity locating pad is made by polyurethane rubber; The technology punch insert is made as and the similar raised line of plate ripple section configuration, and the technology die plate insert is made as the groove with the raised line coupling; The forward and backward two ends of upper and lower core rod of gradation compacting tool set are respectively equipped with technology punch insert and technology die plate insert, and the front end of upper mold core also is provided with the elasticity locating pad; The front end that upper mold core is positioned at the technology punch insert is provided with downward translot of notch or break slot, and the elasticity locating pad is arranged in the groove, and the elasticity locating pad is made by polyurethane rubber; The technology punch insert is made as and the similar raised line of plate ripple section configuration, and the technology die plate insert is made as the groove with the raised line coupling.
Press the plate type heat exchanger plate shaping dies that such scheme is implemented, because the former mold of large tonnage pressing machine that needs is improved to the mould that gradation is suppressed, reasonably solved purpose with little tonnage forcing press compacting and production ultra-large type plate, and under the prerequisite of ensuring the quality of products, realized the production of the not overlapping and uninterrupted uniformity consistency of many molds.The utility model reasonable in design has certain meaning to saving aspects such as investment.
