Abstract
The invention provides a nitrogen-blowing welding process for three temperature zones of a quartz tuning fork crystal. In this design, pure nitrogen is used to replace air to obtain high temperature airflow. The temperature of welding airflow is divided into three temperature zones one after another, wherein the three temperature zones are a drying temperature zone, a preheating temperature zone and a high temperature welding temperature zone. The welding air flow is used to weld a tuning fork sheet and a tuning fork base. Because nitrogen molecule is hard to start a chemical reaction with the metal component of the tuning fork sheet and the tuning fork base, the nitrogen-blowing welding process of the invention enables the product quality to be more stable without oxidation process and dust pollution.
Description
Technical field
The present invention relates to welding procedure during a kind of quartz tuning-fork crystal production, specifically refer to a kind of quartz tuning-fork crystal three-temperature-zone nitrogen flushing method welding procedure.
Background technology
In quartz tuning-fork crystal production field; tuning fork sheet and the tuning fork pedestal traditional handicraft when welding is that heating wire increases temperature air and blows on weld jig by heat-generating pipe air-flow; because air contains steam; dust; oxygen; this tuning fork crystal welding method; make quartz tuning-fork sheet is polluted; under the effect of high temperature, some dust granules can be firmly attached to tuning fork crystal surface; oxygen in air and hydrone at high temperature make pad rapid oxidation, and this traditional tuning fork crystal welding procedure has a strong impact on the production quality of crystal.
Summary of the invention
The object of the invention is to overcome prior art tuning fork sheet and tuning fork pedestal welded type easily pollutes, is easily oxidized Problems existing, the quartz tuning-fork crystal three-temperature-zone nitrogen flushing method welding procedure that a kind of simple, welding quality gets a promotion is provided.
For realizing above object, technical solution of the present invention is: a kind of quartz tuning-fork crystal three-temperature-zone nitrogen flushing method welding procedure, comprises the following steps:
1) open nitrogen making machine, manufacture nitrogen, and check the pressure of nitrogen, reach certain air pressure, nitrogen, through drying machine, filters out the hydrone in nitrogen, obtains dried nitrogen for subsequent use;
2) nitrogen flows to three warm areas respectively via pipeline, three warm areas are respectively dry warm area, preheating warm area and high-temperature soldering warm area, each warm area is provided with heater, heater comprises flow-limiting valve, filter, heater strip and adjustable transformer, first regulate three flow-limiting valves respectively, after making the nitrogen flow of corresponding warm area reach desirable value, wait for 5 minutes, nitrogen is by after the air emptying in pipeline, open three groups of heater strips simultaneously, regulate three groups of adjustable transformers respectively, the temperature arranging three warm areas is respectively: 50-60 DEG C, 80-100 DEG C, 150-200 DEG C;
3) after throughput and temperature regulate, observe 5 to 10 minutes, after checking that throughput and temperature do not fluctuate, fixture to be welded is put conveyer belt, successively by three warm areas, tuning fork sheet and tuning fork pedestal are welded.
Beneficial effect of the present invention is:
Substitute air with pure nitrogen and obtain high temperature gas flow, tuning fork sheet and tuning fork pedestal are welded.The temperature of welding air-flow is divided into into 3 warm areas with sequencing, dry warm area, preheating warm area, high-temperature soldering warm area.Due to nitrogen molecule at high temperature not easily with tuning fork sheet and tuning fork pedestal metal ingredient generation chemical reaction, non-oxidation process, does not have contamination by dust, makes product with stable quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: nitrogen making machine 1, drying machine 2, pipeline 3, dry warm area 4, preheating warm area 5, high-temperature soldering warm area 6, heater 7, flow-limiting valve 71, filter 72, heater strip 73, adjustable transformer 74, conveyer belt 8.
Embodiment
Illustrate that the present invention is further detailed explanation with embodiment below in conjunction with accompanying drawing:
See Fig. 1, a kind of quartz tuning-fork crystal three-temperature-zone nitrogen flushing method welding procedure, comprises the following steps:
1) open nitrogen making machine 1, manufacture nitrogen, and check the pressure of nitrogen, reach certain air pressure, nitrogen, through drying machine 2, filters out the hydrone in nitrogen, obtains dried nitrogen for subsequent use;
2) nitrogen flows to three warm areas respectively via pipeline 3, three warm areas are respectively dry warm area 4, preheating warm area 5 and high-temperature soldering warm area 6, each warm area is provided with heater 7, heater 7 comprises flow-limiting valve 71, filter 72, heater strip 73 and adjustable transformer 74, first regulate three flow-limiting valves 71 respectively, after making the nitrogen flow of corresponding warm area reach desirable value, wait for 5 minutes, nitrogen is by after the air emptying in pipeline 3, open three groups of heater strips 73 simultaneously, regulate three groups of adjustable transformers 74 respectively, the temperature arranging three warm areas is respectively: 50-60 DEG C, 80-100 DEG C, 150-200 DEG C,
3) after throughput and temperature regulate, observe 5 to 10 minutes, after checking that throughput and temperature do not fluctuate, fixture to be welded is put conveyer belt 8, successively by three warm areas, tuning fork sheet and tuning fork pedestal are welded.
Before the start of production, open nitrogen making machine 1, check the pressure of nitrogen, reach certain air pressure, nitrogen, through drying machine 2, filters out the hydrone in nitrogen, obtains dried nitrogen stream, regulate the flow-limiting valve 71 at three places respectively, make the nitrogen of dry warm area 4, preheating warm area 5, high-temperature soldering warm area 6 reach required flow.Particle in filter 72 pairs of nitrogen filters, to improve the cleanliness factor of nitrogen.Pipeline 3 was through the nitrogen stream of several minutes, air in pipeline 3 is discharged, open heater strip 73 again, regulate adjustable transformer 74, be respectively used to the temperature regulating dry warm area, preheating warm area, high-temperature soldering warm area, the temperature of three warm areas is respectively: 50-60 DEG C, 80-100 DEG C, 150-200 DEG C.The process function of each warm area is different, but must keep the stable of each warm area temperature.After throughput and temperature regulate, observe 5 to 10 minutes, check that throughput and temperature do not fluctuate.Checking complete welding fixture by conveyer belt 8, successively by 3 warm areas, tuning fork sheet and tuning fork pedestal being welded.Substitute air with pure nitrogen in the design and obtain high temperature gas flow, tuning fork sheet and tuning fork pedestal are welded.The temperature sequencing of welding air-flow is divided into into 3 warm areas, dry warm area, preheating warm area, high-temperature soldering warm area.Due to nitrogen molecule at high temperature not easily with tuning fork sheet and tuning fork pedestal metal ingredient generation chemical reaction, non-oxidation process, does not have contamination by dust, makes product with stable quality.
