Quantitative lubrication supply device for die-casting machine punching head

Abstract

The invention discloses a quantitative lubrication supply device for a die-casting machine punching head. The quantitative lubrication supply device comprises a quantitative lubrication oil supply cabinet consisting of a lubrication oil tank and an electric control cabinet, wherein a programmable logic controller (PLC), a material injection or returning contactor and an oil pump intermediate relay are arranged in the electric control cabinet; the oil pump intermediate relay is connected with an oil pump control electric board; the material injection or returning contactor is connected with a proximity switch arranged on a die-casting machine; a control panel is arranged on the electric control cabinet; a switch function key group and a display screen which are connected with the PLC are arranged on the control panel; and the material injection or returning contactor controls an oil pump to quantitatively spray lubrication oil to the die-casting machine punching head through the PLC and the oil pump intermediate relay according to a die-casting machine punching head resetting electric signal captured by the proximity switch. The lubrication supply device is easy to operate, runs stably and is high in safety; the utilization rate of the lubrication oil is high; the punching head can be well lubricated; the service life of the punching head is prolonged; and the production efficiency of die-casting equipment can be improved.

Description

Technical field [0001] The invention relates to the lubrication technology of the punch of a die-casting machine, in particular to a punch lubricating device capable of quantitatively controlling the supply of lubricating liquid, in particular to a punch lubrication setting device of a die-casting machine. Background technique [0002] Die casting machine is one of the indispensable equipment in the mechanization today, and its position in the machinery industry is becoming more and more important. It can achieve very small dimensional tolerances of die castings and high surface accuracy. In most cases, die castings can be assembled and applied without turning, and threaded parts can also be directly cast. But as the core part of die casting machine, the punch is one of the parts that is easy to wear and needs frequent replacement and maintenance. The main reason why the punch is easy to wear is that the punch cannot be well lubricated, which results in frequent dry grinding of ...

Problems solved by technology

However, the punch, which is the core part of the die-casting machine, is one of the parts that are easy to wear and need to be replaced and repaired frequently.

The main reason why the punch is easy to wear is that the punch cannot be well lubricated, which leads to frequent dry grinding of the punch and cylinder

In the prior art, due to the difficulty in lubricating punches, it is generally difficult to achieve sufficient lubrication. Therefore, this problem has always been a technical problem in the lubrication of die-casting machine punches until today, making it difficult to improve the die-casting machine. equipment productivity
