Abstract
The invention discloses a forming tool of a capillary tube. The forming tool comprises a pair of common sharp-nose pliers, wherein one side wall of the common sharp-nose pliers is fixedly provided with parallel positioning baffles which are parallel to the side wall and are provided with waist-shaped holes; the waist-shaped holes are internally provided with positioning blocks; the end parts of an upper pliers plate and a lower pliers plate are respectively and fixedly provided with an upper forming mold plate and a lower forming mold plate. The forming tool disclosed by the invention has the beneficial effects that the integrated forming of an upper mold and a lower mold is adopted, so that the structure is simple; the forming mold adopts a groove design and an adjustable positioning baffle, the accuracy of the forming position and the forming length of the capillary tube can be effectively guaranteed, and the design is ingenious; a forming roller adopts tungsten steel and nylon, so that the forming quality of the capillary tube is effectively guaranteed and the quality of a product is improved.
Description
technical field:
The present invention relates to cross valve assembling field, particularly relate to a kind of capillary tube forming tool.
background technology:
Slotting capillary is one important procedure of idle call four-way change-over valve assembling, first carries out the bending of capillary fixed length and inserts in end cap capilar bore, then use special tooling to be knocked by capillary and put in place.This operation key point is that capillary insertion depth is moderate, and mistake is dark or excessively shallow all can affect properties of product.The four-way change-over valve of idle call simultaneously capillary material is Φ 2.5 × 1.5 copper tube, thin and soft.
For above-mentioned technical problem, need and a kind ofly can ensure the length that capillary bends and angle, can ensure that again capillary can not damage the capillary tube forming tool of distortion.
summary of the invention:
In order to make up prior art problem, the object of this invention is to provide a kind of capillary tube forming tool, the length that capillary bends and angle can be ensured, can ensure that again capillary can not damage distortion.
Technical scheme of the present invention is as follows:
Capillary tube forming tool, comprise common nipper plier, it is characterized in that: a sidewall of described common nipper plier is fixed with positioning baffle in parallel, positioning baffle has mounting hole, be provided with locating piece in mounting hole, the nippers of described common nipper plier, nipper plate end are fixed with shaping upper plate, shaping lower bolster respectively.
Described capillary tube forming tool, it is characterized in that: described shaping upper plate is arc, in the middle part of arc, bilateral symmetry has breach, indentation, there is rotatablely equipped with shaping roller, the rotating shaft core line of shaping roller is parallel with the bus of arc, on shaping roller, radially direction has the groove matched with capillary outer wall, and the arc inwall between described breach is provided with the upper groove matched with capillary outer wall.
Described capillary tube forming tool, it is characterized in that: described shaping lower bolster is the cross section of matching with shaping upper plate is fan-shaped cylinder or cylinder, and shaping lower bolster and the mating surface of shaping upper plate are provided with the lower groove matched with capillary outer wall.
Described capillary tube forming tool, is characterized in that: the end face of described shaping upper plate is also provided with the hanging ring of U-shaped.
