Machine tool for continuously quenching slender steel pipe

Abstract

The invention provides a machine tool for continuously quenching a slender steel pipe, which relates to the field of machine tools and comprises a feeding mechanism, a quenching mechanism and a discharging mechanism, wherein the feeding mechanism is connected with the quenching mechanism, the quenching mechanism is connected with the discharging mechanism, the quenching mechanism comprises two groups of rotating rollers, an empty space is formed between the two groups of rotating rollers, a sensor is arranged in the empty space formed between the two groups of rotating rollers, the front end of the sensor is provided with a guide sleeve, the back end of the sensor is provided with a water spraying ring, a water collecting tank is arranged under the empty space formed between the two groups of rotating rollers, and the water spraying ring is connected with the water collecting tank. A reasonable push-pull quenching mode is adopted, and the quenching deformation of the slender steel pipe reaches the minimum range, so workpieces can smoothly rotate, and smooth discharging is realized. During the discharging, the bending is further reduced through straightening, so the straightness accuracy of the workpieces is always kept in the proper range.

Description

technical field [0001] The invention relates to a machine tool, in particular to a machine tool capable of continuously quenching slender steel pipes. Background technique [0002] With the development of the domestic automobile industry and the localization of parts, the blasting tubes of automobile airbags have also been localized. The length of the blasting tubes varies according to different models. In order to reduce the material, manufacturers use long materials after heat treatment. Cut the short material into the required length, and the longer the long material, the less the material head after cutting, the less material, so the manufacturer pursues the longer the steel pipe before cutting, the better, and even requires a steel pipe 6 meters long before cutting, and it must be quenched . Due to the large amount of quenching deformation of the slender tube, the workpiece will be stuck, cannot be rotated, and the workpiece will not be able to move forward when the co...
