Movement with pure-tungsten metal clamp plates

Abstract

The invention discloses movement with pure-tungsten metal clamp plates. By the aid of the movement, problems that existing clamp plates of existing movement of watches are easy to deform and rust, large in temperature coefficient and unfavorable for the time precision of the watches mainly can be solved. The movement comprises a movement body and the clamp plates for supporting the movement body. The clamp plates include an upper clamp plate and a lower clamp plate, journal holes which are used for mounting the movement body are formed in the upper clamp plate and the lower clamp plate, and the clamp plates are made of pure-tungsten metal materials. The movement has the advantages that the clamp plates of the movement of a watch are made of pure-tungsten metal and are difficult to deform and rust, and accordingly the watch is stable for a long term and is high in time precision and long in service life; the clamp plates are low in temperature coefficient, and accordingly the time precision of the watch can be further improved on the basis of the prior art; the clamp plates are high in surface roughness, and accordingly the watch can be high in time precision without jewel bearings; the structure of the movement can be simplified, the dimensional tolerance of the movement can be reduced, and accordingly the time precision of the movement can be improved.

Description

Technical field [0001] The invention relates to a movement using pure tungsten metal splints, and belongs to the field of mechanical manufacturing. Background technique [0002] Watch movements often use mechanical movements and quartz movements. These two movements have their own advantages and disadvantages. Among them, the quartz movement is through quartz Oscillator Converting electrical energy into kinetic energy, using mechanized equipment to mass-produce circuit boards, and matching resistors and capacitors, it can be completed. Its advantages are: accuracy, light weight and easier maintenance; disadvantages: general quartz battery life is only one or two years , Often need to be replaced, and the other is the use of quartz oscillation watches, often used for five to eight years, the quartz oscillation will decline, relatively Accuracy It will be lowered, so you need to change it now. The power of a mechanical movement comes from the mainspring in the movement. The mains...
