Abstract
The invention relates to a method for protecting the shot blasting surface of a grit blasting part. A protection tooling made of canvas is adopted to protect the non-shot blasting surface of the part; as canvas is very soft, the shot blasting surface of the grit blasting part cannot be damaged during mounting and demounting of the protection tooling. The method has the advantages that parts of various structures can be protected conveniently; the protection tooling can be in tight contact with the parts easily; sand can be effectively prevented from being adhered to the shot blasting surface; the protection tooling is convenient and fast to mount and demount. Therefore, the production efficiency can be improved effectively.
Description
Technical field
The present invention relates to a kind of means of defence, especially the means of defence of blast part bead blasted surfaces.
Background technology
The parts of various fields need carry out blast operation, such as adopt the parts of the PROCESS FOR TREATMENT such as thermal spraying, japanning and splicing to need before treatment to carry out blast process to improve the roughness of piece surface, then strengthen matrix and the adhesion being coated with interlayer.Bead is a kind of processing method improving part fatigue strength, bead blasted surfaces is the surface with compressive stress state, in blast process, need to protect the bead blasted surfaces of non-blast, to guarantee that the compressive stress state of bead blasted surfaces is not destroyed by the sand grains of scattering in blast process.Bead blasted surfaces often adopts special tooling or special protection adhesive tape to protect, and special tooling adopts metal material to be prepared from usually, and protection adhesive tape is generally fiber cloth adhesive tape.Adopt said method to protect non-blast bead blasted surfaces and often produce following problem:
1. special tooling is in installation and removal process, as easy as rolling off a log scuffing bead blasted surfaces.Often need to clean to remove to bead blasted surfaces the glue residued on surface after the dismounting of special protection adhesive tape, add workload;
2. in blast process, easily enter the gap between frock (adhesive tape) and bead blasted surfaces through a large amount of sand grains of blast surface rebound, adhere to bead blasted surfaces, easily cause surface damage during cleaning sand grains, destroy bead blasted surfaces stress state;
3. installation and removal frock (adhesive tape) man-hours requirement is longer, reduces production efficiency.
Summary of the invention
The object of this invention is to provide a kind of blast part bead blasted surfaces means of defence, what time following this means of defence meet:
1) protective tooling is in installation and removal process, would not cause damage to bead blasted surfaces and pollute;
2), in blast process, protective tooling should be able to effectively prevent sand grains from adhering to bead blasted surfaces;
3) protective tooling installation and removal are convenient, fast, effectively enhance productivity.
Technology solution scheme of the present invention is, a kind of blast part bead blasted surfaces means of defence comprises the following steps:
(1) design and process protective tooling: protect the bead blasted surfaces design of part as required and process protective tooling, described protective tooling adopts canvas material to make, according to part bead blasted surfaces size and shape canvas material designed and be processed into conformal protective cover, when described conformal shielding cover is on part, can protect not needing the bead blasted surfaces of blast;
(2) install: shielding cover is loaded on part bead blasted surfaces, by not needing the bead blasted surfaces of blast to protect, then protective cover is sealed banding, and protective cover is fixed on piece surface, prevent protective cover and non-blast bead blasted surfaces to be moved;
(3) blast: blast process is carried out to blast surface;
(4) final inspection: after blast terminates, dismantles protective cover, tests to blast surface and bead blasted surfaces.
The present invention selects canvas material to make the non-blast bead blasted surfaces of protective tooling to part and protects, and canvas material quality is soft, and installation and removal can not cause damage to bead blasted surfaces.Meanwhile, canvas material form-dependent character is excellent, the parts of convenient protection various structures, and easily realizes and the fitting tightly of part, and can effectively prevent sand grains from adhering to bead blasted surfaces.In addition, the installation and removal of canvas material protective tooling are convenient, fast, can effectively enhance productivity.
Embodiment 1
Blast process is carried out to the axle shape piece surface that certain diameter is φ 200, closes on blast surface for bead blasted surfaces, require that blast surface is after blast process, surface roughness Ra >=4; Requirement bead blasted surfaces is pollution-free and damage.Its concrete implementation method is as follows:
(1) design and process protective tooling: protect the bead blasted surfaces design of part as required and process protective tooling, described protective tooling adopts canvas material to make, according to part bead blasted surfaces size and shape canvas material designed and be processed into axle shape protective cover, protective cover diameter is φ 230, when described conformal shielding cover is on part, can protect not needing the bead blasted surfaces of blast;
(2) install: shielding cover is loaded on part bead blasted surfaces, by not needing the bead blasted surfaces of blast to protect, then protective cover is sealed banding, and protective cover is fixed on piece surface, prevent protective cover and non-blast bead blasted surfaces to be moved;
(3) blast: carry out blast process to needing blast surface;
(4) final inspection: after blast terminates, dismantles protective cover, tests to blast surface and bead blasted surfaces.
Final result: blast surface roughness Ra 4.7, bead blasted surfaces protection effect is good, without surface damage and pollution.
Claims (1)
1. a blast part bead blasted surfaces means of defence, is characterized in that, described method comprises the following steps:
1) design and process protective tooling: protect the bead blasted surfaces design of part as required and process protective tooling, described protective tooling adopts canvas material to make, according to part bead blasted surfaces size and shape canvas material designed and be processed into conformal protective cover, when described conformal shielding cover is on part, can protect not needing the bead blasted surfaces of blast;
2) install: shielding cover is loaded on part bead blasted surfaces, by not needing the bead blasted surfaces of blast to protect, then protective cover is sealed banding, and protective cover is fixed on piece surface, prevent protective cover and non-blast bead blasted surfaces to be moved;
3) blast: blast process is carried out to blast surface;
4) final inspection: after blast terminates, dismantles protective cover, tests to blast surface and bead blasted surfaces.
