Description
Technical field
The utility model belongs to jewelry processing equipment field, particularly relates to the semi-automatic calender of a kind of gold jewelry.
Background technology
The gold ornaments such as gold bracelet, gold bar, gold coin are the high-end commodity in market, and the flatness of its effects on surface and glossiness have very high requirement, therefore must carry out press polish process to it, and calendaring technology is most important for the appearance of final finished.Existing calendaring technology mostly is workman to carry out by hand, and its operating procedure details is:
1, press finishing tool is push type broach.The material of push type broach is generally wolfram steel, agate etc., and its tip is divided into spherical and pointed according to shape, is different radians according to the polishing of workpiece difference, and push type broach surface forms for fine grinding, and roughness grade number is very high.
2, the plank cotton gauze of back flow tender help station is wrapped, in order to avoid scratch gold surface
3, operative employee one offhand, and it is firm to support holding workpiece by plank, tip is also pressed on the surface of the workpiece by the hand-held push type broach of another hand, and the push type broach that swings back and forth reposefully carries out extrusion operation.
4, in burnishing process, in order to reduce friction, improve the calendaring effect, need to use clear water or suds wetted workpieces surface.
Aforesaid operations technique is comparatively large to the body pressure of workman, the strain of joint such as finger, elbow moving back and forth and easily cause operative employee of having an effect for a long time, and the pain of injury makes workman be difficult to adhere to long-term work, and workman works for a long time and easily occurs " press polish hand " occupational disease.Therefore, for large-scale gold processing enterprise, existing calendaring technology limits the expansion of production capacity.Meanwhile, in manual burnishing process, firmly irregular meeting causes trowel finish out-of-flatness, and the effect of press polish is undesirable, and the efficiency of manual press polish is low.Therefore, urgently a kind of jewellery calender that can alleviate workman's operating pressure, enhance productivity.
At present, for improving the efficiency of this technique, alleviate workman's burden, existing industry related personnel is studied automatic pressing light device, and such as, patent publication No. is that the patent application of CN102794599A proposes a kind of gold jewelry calender with force feedback system; Patent publication No. is that the patent application of CN104148879A proposes a kind of gold bracelet automatic pressing ray machine; Patent publication No. is that the patent application of CN203305216U proposes a kind of noble metal jewelry press polish robot.
