Abstract
The invention discloses a processing method for an integrated FRP mould of rail headstock; as for the structural design, a fixed structure with a pre-buried reinforced steel frame support and an integrated soleplate is adopted to rapidly complete the numerical control milling preforming of a mould curved face; the surface is coated with mould paste resin and is pre-buried with a welding frame; polystyrene female mould material is removed after the mould paste resin is solidified to obtain the integrated mould blank, and then the fine milling process of the integrated mould streamline curved face is assembled on a numerical control gantry milling once based on the programming of a mathematical model; and all precision is guaranteed completely by numerical control processing, and each curved face curvature completely meets the requirements of the original mathematical model. The processing method has stable precision in mould size, short period in processing, beautiful integrated appearance and convenient transportation.
Description
Technical field:
The present invention discloses a kind of processing method for integrated Fiber Reinforced Plastic (FRP) mould of rail headstock, is used for the processing of large glass steel mold such as city rail, subway headstock, belongs to mould production and processing technical field.
Background technology:
At present, be to adopt plank setting-out composting structure basically for the processing of the whole fiber reinforced plastic mold of city rail, subway headstock, artificial thinning technique is made: obtain the model cross section by three-dimensional 1: 1 Mathematical Modeling along the intercepting of Z direction even laminating earlier; According to the processing of the model cross section after intercepting plank; Plank is enumerated according to the height of digital-to-analogue layering intercepting; Model surface is filled with certain thickness timber; By the wooden model surface of carpenter's hand grinding, make die needed at last.This plank setting-out piece composting structure of continuing to use is accepted for many years by the fiber reinforced plastic mold industry, but shortcoming is that drawing setting-out and plank composting are long in time limit, expend timber expense height, to environment temperature and humidity requirement strictness, easily deformable etc., because curved surface is adopted artificial reconditioning moulding process, the die size precision of making is relatively poor, can't guarantee that mould meets the design philosophy of former mathematical model fully, more can't guarantee the accuracy of form and position of rill line style headstock curved surface.
Summary of the invention
The invention provides a kind of processing method for integrated Fiber Reinforced Plastic (FRP) mould of rail headstock, it is long in time limit to have overcome existing plank setting-out piece composting method drawing setting-out and plank composting, expends timber expense height, the shortcoming of die quality difference.
Technical solution of the present invention may further comprise the steps:
1, make former:
Die size according to design goes out former with the digital control processing of polyphenyl ethylbenzene cystosepiment.
2, Tu Daimu:
The pasty state that epoxy resin (H6403A) and curing agent (H6405-1B) are mixed according to 1: 1 ratio is evenly coated on the former for wood, and coating layer thickness 40-60mm waits for and solidifying.
3, bonding steel skeleton:
After pasty state solidifies for wood, steel skeleton with the chopped mat of 2 layer of 300 gram/square meter, the glass fabric of 2 layer of 600 gram/square meter, is successively pasted on the Dai Mu that is bonded in after the curing with epoxy resin, treat behind the resin solidification smooth unnecessary rim charge processing.
4, defoam:
Polystyrene foam plate is removed, thereby obtained formpiston.
5, digital control processing:
Formpiston is carried out digital control processing by design size get mould of the present invention.
The present invention's good effect compared with prior art is: on structural design, adopt pre-buried reinforcement steel skeleton to support, whole chassis fixed structure, finish the numerical control milling preformed of die curve fast, the surface-coated model is stuck with paste resin and pre-buried welded framework, place to go polystyrene former material is obtained the unitary mould blank after treating model paste resin solidification, programme according to Mathematical Modeling then, once clamping is finished the finish-milling processing of the streamlined curved surface of unitary mould on numerical control gantry mill, guarantee every precision by digital control processing fully, each curvature of curved surface meets former Mathematical Modeling requirement fully.The die size stable accuracy, the process-cycle is short, overall appearance, convenient transportation.

The specific embodiment
Embodiment 1
1, makes former
Digital control processing goes out former 2, and the former material is a polystyrene foam plate.Former profile 3 is to obtain by die face 1 skew 5-10mm, and this 5-10mm is as the allowance of routing up mould behind the formpiston.(seeing accompanying drawing 1 and Fig. 2)
2, be coated with pasty state model resin
At normal temperatures and pressures epoxy resin (H6403A) and curing agent (H6405-1B) are mixed according to 1: 1 ratio, be placed on aeration-drying place, both produce chemical reaction, thereby obtain pasty state model resin 4; Pasty state model resin 4 is evenly coated on the former 2, and coating layer thickness 40-60mm waits for and solidifying.Slightly variant according to different hardening times in season, in general 8 to 12 hours winters, be about 8 hours summer.(seeing accompanying drawing 3)
3, bonding steel skeleton
After pasty state model resin 4 solidifies, is matrix with steel skeleton 5 with the chopped mat 6 of 2 layer of 300 gram/square meter and the glass fabric 7 of 2 layer of 600 gram/square meter, successively paste on the model resin that is bonded in after the curing with epoxy resin 8, treat to handle unnecessary rim charge smooth behind the resin solidification.(seeing accompanying drawing 4)
4, defoam
The former removal is obtained formpiston 9, and formpiston profile 10 is identical with former profile 3.(seeing accompanying drawing 5)
5, digital control processing
Formpiston is carried out digital control processing obtain mould 11, digital control processing is removed formpiston profile 5-10mm surplus and is obtained die face 1.(seeing accompanying drawing 6).
