Abstract

Pipe, is first assemblied in the endoporus of plate type heat exchanger pressing plate, is supported on lower mould by a kind of method of mould pressing plate type heat exchanger grommet, and lower mould enters row constraint to tube blank inner wall and lower fillet;The spinning head of corresponding spinning angle is selected, spinning head rotates around own axes, while spinning head, in the axial direction to lower feeding, feeding process should ensure that spinning head is identical with pipe axis;Spinning head continues to feed, and after the free end in contact of pipe, deformation takes place in pipe free end, until pipe free end all expand for spinning head identical angle;Spinning head is replaced by flattening die;Flattening die moves downward in the axial direction, with starting to be flattened after the free end in contact of pipe, until free end all turns into 90 °, completes the shaping on plate type heat exchanger lined flange side;Flattening die exits, and obtains the plate type heat exchanger pressing plate with grommet;The present invention realizes the shaping on plate type heat exchanger lined flange side, and mould structure is simple, improves processing efficiency and forming quality.

Description

A kind of method of mould pressing plate type heat exchanger grommet
Technical field
The invention belongs to advanced forming technique field, and in particular to a kind of method of mould pressing plate type heat exchanger grommet.
Background technology
Plate type heat exchanger is a series of a kind of high-performance heat exchanger formed by sheet metal closed assemblies with certain bellows-shaped, Plate type heat exchanger grommet is the strength member on plate type heat exchanger.It is on active service in the cycle, heat exchanger plate needs periodic cleaning, but serves as a contrast Ring can not be dismantled, clean difficulty, and the metal grommet of cold and hot fluid/gas import and export wishes to be served in the whole Life Cycle of heat exchanger Phase.
But plate type heat exchanger grommet is manufactured using the method on both ends flange splicing side more at present, or grommet end flange Processed using plastic methods such as punching presses, another end flanges use welding forming technique after being assembled with plate type heat exchanger pressing plate.Metal The weld seam on lined flange side easily corrodes without product appearance is influenceed, influences the service life of heat exchanger during service, Larger deformation can be produced after increasing the maintenance difficulties of heat exchanger, the particularly welding of heavy caliber plate type heat exchanger grommet, influences plate The normal work of formula heat exchanger.
The content of the invention
In order to overcome disadvantages mentioned above, it is an object of the invention to provide a kind of side of mould pressing plate type heat exchanger grommet Method, mould structure is simple, can effectively improve the forming quality and efficiency on plate type heat exchanger lined flange side, be particularly suitable for heavy caliber The shaping on plate type heat exchanger lined flange side.
In order to achieve the above object, the technical scheme taken of the present invention is:
A kind of method of mould pressing plate type heat exchanger grommet, comprises the following steps:
1), pipe 100 is assemblied in the endoporus of plate type heat exchanger pressing plate 2, be supported on lower mould 3, lower mould 3 is to pipe 100 inwalls and lower fillet enter row constraint;
2) spinning head 1 of corresponding spinning angle, is selected, spinning angle is 40 ° to 60 °;
3), spinning head 1 rotates around own axes, while spinning head 1 should ensure that to lower feeding, feeding process in the axial direction Spinning head 1 is identical with the axis of pipe 100;
4), spinning head 1 continues to feed, and after 100 free end in contact of pipe, deformation takes place in the free end of pipe 100, until The free end of pipe 100 all expand for the identical angle of spinning head 1;
5) spinning head 1, is replaced by flattening die 4;
6), flattening die 4 moves downward in the axial direction, with starting to be flattened after 100 free end in contact of pipe, until from All turn into 90 ° by holding, complete the shaping on plate type heat exchanger lined flange side;
7) flattening die 4 exits, and completes processing, obtains the plate type heat exchanger pressing plate with grommet.
Beneficial effects of the present invention:The present invention uses mould pressing mode, realizes plate type heat exchanger lined flange side Shaping, mould structure is simple, is effectively simplified the process of plate type heat exchanger grommet, and plastic force is small, and it is big to be particularly suitable for processing The processing of bore plate type heat exchanger grommet, improves processing efficiency and forming quality.

Embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
A kind of method of mould pressing plate type heat exchanger grommet, comprises the following steps:
1), reference picture 1, pipe 100 is assemblied in the endoporus of plate type heat exchanger pressing plate 2, be supported on lower mould 3, lower mould 3 Row constraint is entered to the inwall of pipe 100 and lower fillet, avoids deforming in processing;
2), reference picture 2, select the spinning head 1 of corresponding spinning angle, and spinning angle is 45 ° in this embodiment;
3), reference picture 3, spinning head 1 are rotated around own axes, while spinning head 1 was fed in the axial direction to lower feeding Journey should ensure that spinning head 1 is identical with the axis of pipe 100;
4), reference picture 4, spinning head 1 continue to feed, and after 100 free end in contact of pipe, the free end of pipe 100 takes place Deformation, until the free end of pipe 100 all expand for the identical angle of spinning head 1;
5), reference picture 5, spinning head 1 is replaced by flattening die 4;
6), reference picture 5 and Fig. 6, flattening die 4 move downward in the axial direction, with start after 100 free end in contact of pipe by It is flattened, until free end all turns into 90 °, completes the shaping on plate type heat exchanger lined flange side;
7) flattening die 4 exits, and completes processing, obtains the plate type heat exchanger pressing plate with grommet.
