Description
Technical field
The present invention relates to a kind of processing method of spray gun fittings, relate more particularly to a kind of processing method of spray gun trigger, belong to the processing method technical field of spray gun parts.
Background technology
Spray gun is a kind of comparatively common Spray painting tool in daily life, and its scope of application is quite wide, such as, spray gun can be used as the instrument of spray paint or coating, the plurality of advantages such as to have conveniently, laborsaving, efficient.
At present, spray gun kind on market is more, according to feed mode, be broadly divided into three kinds: hydrocone type, gravity type and pressure type, but these spray guns all need hand control trigger to carry out operation when operating, and the pole of figure of trigger is irregular, such as, shown in the accompanying drawing 1 of this description and Fig. 2: trigger is a bathtub construction on the whole usually, there is two side plates 2 and a base plate 1, side plate 2 is provided with the hinge hole be connected with rifle body, base plate 1 is provided with successively corners 104, finger pulls portion 103, valve rod pushing part 102 and rifle body relief portion 101; In these parts, especially base plate 1, in order to adapt to each position, its surface is especially irregular; And for example corners 104 has round and smooth bent angle, finger pulls portion 103 and have and point the wide cut, the valve rod pushing part 102 that match and have the projection offseted with valve rod, rifle body relief portion 101 then has vacancy corresponding with rifle shape etc., in addition, the hinge hole on side plate is last procedure in forming operation.The parts that numerous rule like this differs, make when making trigger very difficult, its production process reaches tens roads, this considerably increases production cost, and is not easy to the control of precision.
Based on above defect, spray gun manufacturer have employed multiple improving one's methods and/or operation, such as:
1, in order to simplify production technology, reducing production cost, trigger being adopted cast member, thus can be mass, but casting the trigger obtained is solid construction, instead of bathtub construction.In addition, although technique simplifies to some extent, the weight of trigger but increases a lot.
2, the technique that business adopts plate stamping shaping makes, and obtained trigger is lightweight, intensity good, and shape also can ensure, can extensively use in the art.But when using Sheet Metal Forming Technology to make trigger at present, first slab 3 is produced, then slab 3 is placed in die cavity the semi-finished product stamping out trigger, as shown in the accompanying drawing 3 of this description, in blanket 3, dotted line represents the position that needs bend, this impact style can only stamp out the semi-finished product of a trigger at every turn, because side plate 2 distortion of both sides can cause slab 3 simultaneously from edge toward interior contraction during punching press, need the processing capacity compensating curved arc part between side plate 2 and base plate 1, so cannot the semi-finished product of simultaneously shaping more than one piece trigger on shrinkage direction, simultaneously, when cutting after shaping, residual limit 301 leftover bits are also a lot, all will at least 10 millimeters be had in the every side of rim charge of rifle body relief portion, waste material in corners both sides is then more, cause serious waste of material.
In view of this, develop a kind of processing method of new spray gun trigger, not only there is urgent researching value, also there are good economic benefit and commercial Application potentiality, this just the power place that is accomplished of the present invention and basis lean on.
Summary of the invention
