A punching method for a single-end dislocation circumferential hole of a smoke pipe

Abstract

The invention discloses a punching method for staggered circumference holes in the single end of a smoke pipe. The punching method comprises the following steps that the two ends of the smoke pipe are pressed and positioned through two sets of pressing wheels; a three-jaw chuck is arranged at one end of the smoke pipe, a lead screw drive motor drives the three-jaw chuck to move towards a punch, and the three-jaw chuck drives the other end of the smoke pipe to completely enter the punch; the lead screw drive motor of a lead screw drive module is operated, the smoke pipe is driven to move backwards by the set length L1, and the positions, needing to be punched, of the smoke pipe are determined through a sensor; the punch moves, and a first row of main holes are punched; a chuck drive motor is driven to rotate clockwise by a certain angle, and the punching step and the rotating step are cycled till the main hole punching process is finished; the chuck drive motor is driven to rotate clockwise by a certain angle, meanwhile, the lead screw drive motor is operated in a displacement mode to enable the smoke pipe to move backwards by the set length L2, and the positions are the punching positions of a first row of auxiliary holes; the punch moves, and the first row of auxiliary holes are punched; and the punching step and the rotating step are cycled till the auxiliary hole punching process is finished.

Description

technical field [0001] The invention relates to the field of tobacco pipe processing, and more specifically relates to a punching method for a single-end dislocation circumferential hole of a smoke pipe. Background technique [0002] The smoke pipe is a pipe used for exhausting smoke. One end of the smoke pipe is punched with a circle of pin holes along the circumference, and a cap needs to be welded on this end; the other end of the smoke pipe usually needs to be flared, and two Mounting holes to mount the flue pipe to exhaust equipment through the flared end and the mounting holes. [0003] Traditional smoke pipe processing needs to go through four processes of flaring, punching installation holes, punching shaft holes and welding caps in sequence. These four processes are all for processing the single end of the smoke pipe, and need to use feeding equipment or manual feeding The smoke pipe is transported to the punching machine or welding device for welding, and then the...

Problems solved by technology

In the existing cigarette pipe circumferential hole punching device, a clamping cylinder is usually used to extend one end of the smoke pipe into the punch press, and then another cylinder is used to drive the smoke pipe to rotate, and another motor is used to drive the clamping cylinder and the smoke pipe to form a punching machine. The overall horizontal movement; this kind of clamping, feeding and rotation method not only has low positioning accuracy, but also is cumbersome to operate and has a low degree of automation. It often requires manual assistance to complete the punching operation; especially in the process of punching misplaced holes, it is easy to cause the punching position An error occurred
