Description

Technical Field

[0001] The utility model relates to the field of pipe processing equipment, in particular to an air blowing push rod. Background Art

[0002] With the development of science and technology, upgrading traditional industries with modern and automated equipment has become an inevitable choice for the optimization and upgrading of China's manufacturing industry. This requires that the lathe be equipped with an automatic feeding mechanism. The automatic feeding device of the lathe refers to the automatic feeding of the lathe that can continuously process materials in a cycle, thereby improving the processing efficiency and automation of the equipment. The use of automatic feeding on the lathe can reduce labor costs. However, during turning, as the processing progresses, the length of the pipe gradually becomes shorter, and the waste chips will enter the spindle and the inside of the chuck through the pipe during turning, thereby affecting the spindle feeding and the chuck clamping effect.

[0003] The invention patent with Chinese patent application number CN202121187121.3 discloses an automatic feeding device for a lathe, including a cylinder, a cylinder bracket, a blowing nozzle, a feeding channel, a hydraulic chuck and a distribution cabinet.

The utility model transports the material in the feeding channel to the processing position through the setting of the cylinder and the blowing nozzle, and also connects the signal of the distribution cabinet to achieve the purpose of automatic feeding through the distribution cabinet. The non-follow-rotating design of the spindle of the blowing structure composed of the cylinder and the blowing nozzle of the utility model is not affected by the high speed of the spindle. The delay regulator is added to make the material length positioning more accurate to avoid causing processing size errors. The dual solenoid valve control of the second and third solenoid valves makes the larger material slide smoothly in the sleeve and respond in time without affecting the processing speed.

[0004] However, in the utility model, there is a distance between the air blowing nozzle and the material, so that the waste chips still enter the interior of the main shaft and the chuck through the pipe. Utility Model Content
