Abstract
The invention relates to a drive mechanism connecting rod of a micro-compressor, in particular to a treating process for a drive mechanism connecting rod injected and moulded by polyformaldehyde plastics. The treating process for the drive mechanism connecting rod of the micro-compressor is characterized by comprising the following steps of: after injecting and moulding by using the polyformaldehyde plastics, storing at room temperature for 24 hours; carrying out heat treatment for 2-4 hours at 100-140 DEG C; naturally cooling for 2 hours; injecting lubricating grease resisting the temperature of 180 DEG C at the drive connecting position; baking for 1-2 hours at 100-140 DEG C for later installation; installing and running for 30 minutes at full speed; and reinjecting the lubricating grease at the separated connection position to obtain a finished connecting rod product. The treated connecting rod can form a hard oil film and achieve the function of replacing bearings.
Description
Affiliated technical field
The present invention relates to drive mechanism connecting rod of micro-compressor, particularly be injection molded into the drive mechanism connecting rod treatment process with acetal plastic.
Technical background
Producing the micro-compressor connecting rod generally with metal or injection molding at present, connecting rod adopts ball bearing with being connected of transmission mechanism, micro-compressor noise index request harshness, be easy to make a noise during the ball bearing high speed rotating, bearing with high-quality or import is costly, therefore needs the connecting rod of homemade high-quality to emerge.The inventor tests in a large number and finds a kind of novel link treatment process, can make that the connecting rod after handling forms hard oil film, reaches the function that substitutes bearing.
Summary of the invention
Goal of the invention
The invention provides a kind of novel connecting rod treatment process, can make that the connecting rod after handling forms hard oil film, reach the function that substitutes bearing.
Technical scheme
A kind of treatment process that is used for drive mechanism connecting rod of micro-compressor, it is characterized in that with after the acetal plastic injection mo(u)lding, room temperature was deposited 24 hours, through 100-140 Celsius ℃ heat treatment 2-4 hour, naturally the cooling 2 hours, inject the lubricating grease of 180 ℃ of heatproofs at the place of being in transmission connection, through 100-140 Celsius ℃ of temperature baking 1-2 hour, to be installed again, back full speed running 30 minutes is installed, break away from the junction and fill with lubricating grease once more, obtain the connecting rod finished product.
Can be optimized for as a kind of optimal way: after the acetal plastic injection mo(u)lding, room temperature was deposited 24 hours, through 120 ℃ of heat treatment Celsius 2 hours, naturally cooling is 2 hours, injects the lubricating grease of 180 ℃ of heatproofs at the place of being in transmission connection, again through 120 ℃ of temperature baking Celsius 1 hour, to be installed, back full speed running 30 minutes is installed, breaks away from the junction and fill with lubricating grease once more, obtain the connecting rod finished product.Described disengaging junction is filled with lubricating grease once more, is in order to replenish through the grease of 120 ℃ of temperature baking Celsius polyformaldehyde absorption in 1 hour and the grease of the first running formation oil film loss.
The lubricating grease that described heatproof is 180 ℃ is the high temperature grease of market sale, and its heatproof is higher than 180 ℃.Described acetal plastic is available from E.I.Du Pont Company.
Beneficial effect
1, the present invention is on the traditional handicraft basis, innovate, after the traditional injection moulding moulding, heat-treat again and technology such as grease-added, make the endoporus whole circumference face at the place of being in transmission connection can form the bright especially hard oil film of one deck, and lubricating grease infiltrates in the acetal plastic, thereby its coefficient of friction spy is little, and is durable especially, because ball bearing is often easy to wear, so be better than ball bearing, reach the function that substitutes bearing.According to national regulation, all connecting rods dispatch from the factory to be needed through the low-voltage firing test, and requiring percent of pass is 100%, and the connecting rod that adopts traditional handicraft to make generally has 5% disqualification rate at least, but adopts technology of the present invention, can reach 100%, satisfy the regulation of national standard.
2, obtain connecting rod after the PROCESS FOR TREATMENT of the present invention,,, be fit to micro-compressor production so weight is relatively little owing to be that acetal plastic is made.
3, PROCESS FOR TREATMENT of the present invention obtains connecting rod, because the lubricating oil film protection is arranged, thus generally do not need additionally to add lubricating oil, and its noise is seldom.
4, through the connecting rod of PROCESS FOR TREATMENT of the present invention, low cost has price advantage in market, especially for the import connecting rod.
