Abstract

The invention discloses an active cooling process for machine tools. A cooling system utilizing the active cooling process mainly comprises a controller, a frequency converter, a pump and a flow rate monitor. Parameters such as rotational speed of workpieces, actual power of machine tool spindles, or rotational speed of tools and feed rate during operation of the machine tools are input by the controller in an automatic extracting or by-hand input manner, and by treatment of the cooling system utilizing the active cooling process, supply of cooling liquid can keep dynamically balanced with a running state of the machine tools on the premise of meeting cooling requirements of operations of the machine tools, so that the purpose of reducing energy consumption of the machine tools is achieved. By the active cooling process of the machine tools, the machine tools are cooled effectively, energy utilization rate is increased, and energy saving effect is remarkable.

Description

The lathe Active Cooling
Technical field
The invention belongs to Machine Tool design and manufacturing technology field, the flow of cooling fluid can be according to the automatic lathe Active Cooling of regulating of the duty of lathe when being specifically related to a kind of lathe work.
Background technology
Cooling system is the important component part of lathe, and the purpose of cooling is in order to reduce the temperature of processing district, to avoid workpiece burn, improving the crudy of workpiece and the durability of cutter (or emery wheel).
The cooling technology that existing lathe adopts usually is to utilize pump that cooling fluid is pumped directly to the position that the processing district need to be cooled off with constant flow.The defective that this cooling technology exists is no matter which type of duty lathe is in, as long as the lathe cooling system is opened, pump just all the time with constant power running, that is to say that its energy consumption is exactly constant as long as cooling system is started working.This sees it is science not from environmental protection and energy-conservation angle, and is irrational.Simultaneously, be not that lathe all needs cooling fluid to keep larger flow under all duties yet.
In fact, lathe when work, the parameters such as the actual demand amount of cooling fluid and machine tool rotating speed, workpiece rotational frequency, tool feeding amount there are much relations.When cutter and workpiece rotational frequency are higher, when the tool feeding amount was larger, workpiece and cutter caloric value were large, and be also large to the demand of cooling fluid, and this just needs cooling fluid to have larger flow, can have more coolant pump to send into the processing district in the unit interval.On the contrary, when cutter and workpiece rotational frequency lower, the tool feeding amount hour, workpiece and cutter caloric value are little, demand to cooling fluid is also little, and cooling fluid just can satisfy lathe operation needs under less flow, and pump does not just need full-speed operation so, if pump still remains under the relatively high power and works, part energy will waste.
Summary of the invention
The deficiency that exists for overcoming present lathe cooling technology, the invention provides a kind of lathe Active Cooling, this technology makes the supply of cooling fluid under the prerequisite that satisfies lathe operation cooling requirement, can keep with the duty of lathe a kind of dynamic balance, thereby realize reducing the purpose of lathe energy consumption.
For achieving the above object, the present invention adopts following technical scheme:
The front end that described lathe Active Cooling is pump in cooling system increases controller and frequency converter, at delivery side of pump flow monitor is installed, workpiece rotational frequency during by the automatic extraction of controller or manual input lathe work, the parameters such as the actual power of machine tool chief axis or cutter rotating speed and tool feeding amount, by controller these parameters are processed, obtain lathe under this duty, the suitable parameter of required coolant rate in unit interval, and convert the curtage signal to and send to frequency converter, regulated the real work rotating speed of pump by frequency converter, thereby regulate the flow of the cooling fluid of pump output, simultaneously, the actual flow of the flow monitor Real-Time Monitoring pump output terminal cooling fluid by being installed in pump output terminal, and with the signal feedback that monitors to controller, the running parameter of cooling system is revised and optimized by controller, thereby satisfy the cooling requirement of lathe under the different operating state, realize the dynamic equilibrium of lathe duty and cooling effective supply, reach energy-saving and cost-reducing purpose.
Described lathe Active Cooling, its controller gathers lathe real work parameter and can realize by dual mode, and the one, automatically extracted by controller, the 2nd, by the mode of manual input, artificial real work parameter typing with lathe.
Actual power or cutter rotating speed and the tool feeding amount of workpiece rotational frequency, machine tool chief axis when described lathe Active Cooling, the lathe real work parameter of its controller collection are mainly lathe work.
Described lathe Active Cooling adopts the mode of the flow parameter of the manual cooling fluid that pump output is set, and satisfies the cooling requirement under the special operation condition.
Because adopt technique scheme, the present invention has advantages of the following aspects:
1. know-why of the present invention is fairly simple, implements easily, and cost is lower.
2. the present invention can be according to the actual working state of lathe, and the supply of active adjustment cooling fluid improves cooling effect.
3. the present invention's power of active adjustment pump according to actual needs, capacity usage ratio is high, and energy-saving effect is obvious.
