Description

Laser cutting machine that automobile parts production was used Technical Field The invention relates to the technical field of laser cutting, in particular to a laser cutting machine for producing automobile parts. Background Currently, laser cutting equipment is widely adopted in the field of automobile part manufacturing, and a core structure of the laser cutting equipment generally comprises a two-dimensional motion platform and a laser cutting head. The motion platform is driven by a servo motor to realize longitudinal and transverse movement, and the precision of a cutting path is ensured through guide rail guiding. The laser cutting head can generate significant heat accumulation when continuously operated at high power, and the service life of the optical element and the cutting quality are directly influenced. The existing cooling scheme generally depends on an external independently arranged electric water pump system, and forced circulation cooling liquid flows through an internal pipeline of the cutting head to dissipate heat. The design not only additionally increases the power load of equipment, but also has delay in cooling response, is difficult to match with the rapidly-changing temperature state in the cutting process in real time, and is easy to cause local overheating or cooling redundancy. In addition, the motion platform of the laser cutting machine generates a large amount of inertial kinetic energy when the laser cutting machine is started and stopped at a high speed and the direction is switched. In the prior art, this energy is typically dissipated by mechanical damping structures or friction braking means and is not effectively captured and utilized. Meanwhile, the cooling liquid directly flows back to the liquid storage tank after heat exchange is completed, and the heat carried by the high-temperature liquid is discharged only by means of natural heat dissipation or external heat exchange equipment, so that a heat energy recovery mechanism is lacked.
