Description

一种冷却液分流散热的切割机 Cutting machine capable of diverting cooling liquid and dissipating heat 技术领域Technical field
本发明涉及切割机领域，具体涉及的是一种冷却液分流散热的切割机。 The invention relates to the field of cutting machines, in particular to a cutting machine with a cooling liquid splitting heat dissipation.
背景技术Background technique
切割机主要用于在机械加工过程中，对板材进行切割分离。现有的切割机主要在主轴箱内设有转动连接的主轴，主轴上安装切割锯片，并且通过驱动装置驱动主轴转动，从而带动切割锯片进行切割。在切割过程中，由于主轴高速转动，会使得主轴和轴承的温度过高，从而使主轴和轴承膨胀，影响切割精度。The cutting machine is mainly used to cut and separate the plates in the machining process. The existing cutting machine is mainly provided with a rotatingly connected main shaft in the main shaft box, a cutting saw blade is installed on the main shaft, and the main shaft is driven to rotate through a driving device, thereby driving the cutting saw blade to perform cutting. During the cutting process, due to the high-speed rotation of the main shaft, the temperature of the main shaft and the bearing will be too high, which will cause the main shaft and the bearing to expand and affect the cutting accuracy.
为了解决上述主轴和轴承温度过高的问题，现有的切割机大多向主轴箱内通入冷却液，通过冷却液吸热的方式来对主轴和轴承进行散热冷却处理。而现有的切割机在冷却过程中并未对冷却液的用量进行计算，若冷却液用量过少，则冷却液的吸热量较少，无法达到预期的散热效果；若冷却液用量过多，则会导致冷却液浪费的现象，加大了散热成本。In order to solve the above-mentioned problem of excessively high temperature of the main shaft and the bearing, most of the existing cutting machines pass coolant into the main shaft box, and perform heat dissipation and cooling treatment on the main shaft and the bearing by means of heat absorption by the coolant. However, the existing cutting machine does not calculate the amount of coolant during the cooling process. If the amount of coolant is too small, the heat absorption of the coolant is less, and the expected heat dissipation effect cannot be achieved; if the amount of coolant is too much , It will lead to the phenomenon of waste of coolant and increase the cost of heat dissipation.
有鉴于此，本申请人针对上述问题进行深入研究，遂有本案产生。In view of this, the applicant conducted in-depth research on the above-mentioned problems, and this case was born.
