Description

Technical Field

[0001] The invention relates to the technical field of stamping machines, and in particular to a stamping machine bearing temperature monitoring system. Background Art

[0002] At present, stamping processing in mechanical processing occupies an important position in the processing industry of the national economy. The application field of sheet metal is extremely wide, penetrating into all aspects of the manufacturing industry. The sheet metal forming is mainly achieved by pressurized stamping dies. The stamping process has a series of advantages such as high precision, high efficiency, good quality, cost saving, material and energy saving.

[0003] The current stamping machine drives the flywheel through an electric motor, and through the clutch, the transmission gear drives the crank connecting rod mechanism to make the slider move up and down, driving the stretching die to form the steel plate. The so-called double action means that the press has two sliders, divided into an inner slider and an outer slider. The inner slider drives the punch or die of the die, and the outer slider drives the blank holder on the die. During stretching, the blank holder first moves to press the edge of the steel plate, and then the inner slider moves to stretch. The design principle is to convert circular motion into linear motion. The main motor outputs power to drive the flywheel, and the clutch drives the gear, crankshaft (or eccentric gear), connecting rod, etc. to achieve the linear motion of the slider. The movement from the main motor to the connecting rod is circular motion. There must be a transfer point between circular motion and linear motion between the connecting rod and the slider. There are roughly two mechanisms in its design, one is ball type and the other is pin type (cylindrical type). Through this mechanism, the circular motion is converted into the linear motion of the slider. The punching machine applies pressure to the material to cause it to plastically deform and obtain the required shape and precision. Therefore, it must be equipped with a set of dies (divided into upper and lower dies) to place the material between them. The machine applies pressure to cause it to deform. The reaction force caused by the force applied to the material during processing is absorbed by the punching machine body.

[0004] At present, people have higher and higher requirements on the precision of mechanical manufacturing, and the precision requirements for stamping machines have also increased accordingly. However, due to the temperature changes inside the stamping machine during use, thermal expansion effects and other factors cause the manufacturing precision to decrease, which in turn leads to a decrease in production efficiency.
