Description
Technical field
The utility model belongs to the technical field of impact molding machine, relates in particular to a kind of plate-fin heat exchanger high accuracy fin forming machine.
Background technology
Plate-fin heat exchanger is the heat exchanger of all kinds of gas separation equipments, is widely used in the fields such as petrochemical industry, Aero-Space, and plate-fin heat exchanger has compact conformation, and is lightweight, and the advantage of heat exchange efficiency, especially heat exchange efficiency are higher by 30% than other heat exchangers.Fin is the critical component of plate-fin heat exchanger, accounts for more than 80% of whole heat exchanger volume, the heat exchange efficiency of the accuracy affects plate-fin heat exchanger of fin and reliable, security performance.
Also having in the market specially in order to producing the forming machine of fin, is that the Chinese utility model patent " a kind of bending stamper " of 200720114255.6 (notification number is CN201077154Y) has disclosed a kind of fin molding machine such as the patent No..
This kind lathe can satisfy the processing and forming requirement of common fin, can not apply to the processing and forming of plate-fin heat exchanger high accuracy fin, upgrading along with the plate-fin heat exchanger industry, pressure and the heat transfer rate of heat exchanger are had higher requirement, and this all must rely on the formed precision that improves plate-fin heat exchanger fin to guarantee.
So it also need improve in the following areas:
1, according to the requirement of plate-fin heat exchanger fin moulding process, the reciprocating motion on the existing vertical direction of lower tool rest has again the reciprocating motion on the horizontal direction.The wing high accuracy of the jumping effect fin on the lower tool rest vertical direction, the levelness of the reciprocating amplitude of lower tool rest and slippage directly affects the pitch accuracy of fin, in order to produce the high accuracy fin, must aspect these two, improve original lower tool-apron structure.
2, aforementioned pitch adjustment structure is that single fulcrum is regulated, and the stationarity of the second plate slippage is relatively poor, is difficult for producing the high accuracy plate-fin heat exchanger fin.
3, the mould of new plate-fin heat exchanger fin adopts fixedly ejection technique, and corresponding different moulds, the height of stripper plate and front and back position all need constantly to adjust, and this requires the mould frame mechanism of new model will possess steadiness and adjustability.
4, owing to be provided with the parts such as tool rest and mould on the lower bolster, the weight of whole lower bolster is very large, move to the matched moulds process at lathe, the weight that lower bolster also needs to bear whole lower bolster i.e. the power of four die sinking springs, the lower cam drive of lower bolster below is stressed very large, also so that between lower cam and the bottom roller wearing and tearing large, therefore have a strong impact on service life of lower cam drive.
5, because drive motors is fixed on a side of upper base plate (upper machine plate), the discontinuity of upper base plate, so after long-time, the upper base plate opposite side easily produces inclination upwards, cause being arranged between overhead cam between upper base plate and the cope match-plate pattern and the bottom roller and do not reach the position, affect folding mould precision; Original upper base plate can only carry out the up and down adjusting of height in addition, and two stop nuts (position-limited wheel) can only rotate synchronously, so the levelness of upper base plate can not be adjusted by single stop nut.
In sum, existing plate-fin heat exchanger high accuracy fin forming machine also need be done a large amount of improvement.
