Kunshan RiRixian Precision Machinery has obtained a patent for a cooling nozzle for grinding machining centers. It facilitates quick closing of the nozzle and rapid discharge of coolant to prevent residue. It facilitates rapid closing of the nozzle and rapid discharge of coolant to prevent residue.
During the grinding process, the coolant will drip directly from the nozzle onto the surface of the workpiece. This has always been an old headache for many workshop masters. By September 2024, a company in Suzhou that specializes in the production of special equipment submitted and applied for a new patent. This patent was specifically designed to solve the specific problem of dripping.
How annoying is coolant dripping?
Spots appear on the surface of the workpiece
During the grinding process, coolant will be continuously sprayed into the gap between the grinding tool and the workpiece being processed. Its main purpose is to cool down and provide lubrication. If the nozzle is closed and stops working, the residual liquid connected to the mouth of the pipe will slowly drip down at a relatively slow speed and directly onto the surface of the parts that have been processed. This will form very obvious water stains and various spots. This will have a direct negative impact on the related roughness assessment indicators.
Rework costs are not low
As long as there is dirt on the surface, workers will have to perform re-grinding or cleaning. Once the number of workpieces involved reaches dozens, and the components that need to be reworked reach more than a dozen, all the time and material costs will be wasted, because the profit margin left by the small batch order itself is already very weak, so it is simply impossible to withstand such repeated tossing.
What has this company in Suzhou done?
20 years in the subdivision track
This company was registered in Suzhou in 2006. Its registered capital is 1.5 million yuan, and its main business is the manufacturing of special equipment.
According to the information displayed on Tianyancha, it can be found that there are a total of 54 patent records and 1 trademark. In addition, it has obtained 2 administrative licenses. This company has taken root and developed in the grinding and cooling subdivision field for nearly twenty years.
Make widgets the best they can be
There are 54 patents. These patents are not distributed in broad general directions. They are concentrated in very specific aspects such as cooling and transportation of grinding machining centers. The new patent this time is specifically designed to work on the specific point where residual liquid drips from the cooling nozzle. It has been improved at the structural level.
Core design of new patent
Sealing plate plus baffle linkage
This patented technology combines the main cylinder, exhaust pipe A, communication chamber, exhaust pipe B and sealing liquid assembly into an integral structure. When liquid needs to be sprayed, the sealing plate will move downward with the baffle, so that the channel is opened. When the action of spraying the liquid is completed, the sealing plate will move up and return to its original position, thus sealing the nozzle tightly and the liquid will not flow out.
Two sets of one-way valves are responsible for blowing air
When the sealing plate is reset, it will squeeze the air inside the installation tube. The air will first go to a place called one-way pressure valve A, then enter the exhaust pipe A, the connecting chamber and the exhaust pipe B, and then be discharged from the one-way pressure valve B. This forms a downward airflow and blows away the remaining liquid.
How does blowing and draining work?
Automatic cleaning in three steps
This whole thing doesn't require any external equipment at all. Specifically, like spraying liquid, the sealing plate needs to be reset, and then squeezing the air, and finally using the blowing action to remove the liquid. Everything is done within the structure itself.
Workers don't have to press anything in front of the operation panel, such as the air blow button and the like. Therefore, the possibility of accidentally shaking hands or misoperation has indeed become much smaller.
The response speed determines the speed of liquid discharge
This patented solution connects two exhaust pipes and connects them in parallel to a connected chamber. This approach can make the cross-sectional area of the passing air wider and shorten the duration of the blowing action. Since the residual liquid can be drained away faster, it is not easy for the liquid to accumulate again while the workpiece is still in an accurate position. In this way, the overall processing rhythm can become tighter.
Industry demand for precision cooling is rising
High-end parts cannot tolerate droplet contamination
Currently, the requirements for grinding surface roughness of precision parts such as new energy vehicle battery cases, semiconductor silicon wafers, and aviation blades are becoming more and more stringent. In the actual production process, even if the droplet contamination causes an impact on the scale of tens of microns, it is very likely to directly lead to the scrapping of the workpiece. Therefore, the necessity of refining the cooling system has become very prominent, which is already an irreplaceable need.
We can no longer keep up with manual wiping.
In the past, solving the problem of dripping mainly relied on manual wiping or lengthening the nozzle. Not only was this inefficient, it was also easy to damage the workpiece. Using sealing followed by air blowing as a structural solution is more in line with the general direction of equipment integration and automation upgrades.
Barriers created by fifty-four patents
Spend your limited budget wisely
The registered capital of this company is only 1.5 million yuan, which is not a large amount in the manufacturing field. However, the 54 patents they hold are all focused on the small specialized field of grinding cooling.
This phenomenon shows that the company has concentrated its R&D resources on some relatively subdivided specific directions. The result of this is that they form an accumulation. This kind of accumulation is unique and difficult to cover with ordinary general technical solutions.
The next step is to see mass production.
The patent was applied for in September 2024, and there is still a review cycle in between. If you want to truly reduce dripping accidents in the workshop, you have to see whether this set of seals and air blowing structures can be installed in batches on some existing grinding machine tools at a relatively low cost, and it also needs to be adapted to different models.
