Driving device for pipe reducing device

Abstract

The invention discloses a driving device for a pipe reducing device, which comprises a motor, a first transmission mechanism and a second transmission mechanism. The first transmission mechanism comprises a large belt pulley and a first reduction gear which are coaxially mounted, the second transmission mechanism comprises a second large reduction gear and a second small reduction gear which are coaxially mounted, the large belt pulley is in transmission connection with a small belt pulley mounted on an output shaft of the motor, the second large reduction gear is engaged with the first reduction gear, a large gear is fixedly sleeved outside an outer sleeve of the pipe reducing device, and the second small reduction gear is engaged with the large gear. The driving device adopts the motor for driving, the outer sleeve rotates along the longitudinal central axis of a clamping assembly fixing seat, and rollers continuously rotate to press a pipe orifice inwards, so that the pipe orifice can be uniformly reduced. Besides, the degree of mechanization is higher, and the labor intensity of workers is reduced.

Description

Technical field [0001] The invention relates to the field of nozzle processing, in particular to a driving device for a tube shrinking device. Background technique [0002] Both the riser and the evaporator tube include an inner tube and an outer tube. During processing, the outer tube needs to be sleeved outside the inner tube, and the nozzle of the outer tube and the wall of the inner tube must be welded together. There are many factors such as the need for matching. The inner diameter of the outer tube needs to be larger than the outer diameter of the inner tube, resulting in a large gap between the inner and outer tubes, causing inconvenience in welding. If the welding is not good, it is easy to cause liquid leakage during use. Cause danger; and cause unsightly appearance. [0003] Specially developed a tube shrinking device. Specifically, it can be seen that the applicant’s invention patent application number is: "CN201010600472.2", and the invention name is "A tube shrinking...

Problems solved by technology

[0002] Both the riser tube and the evaporator tube include an inner tube and an outer tube. During processing, the outer tube needs to be placed outside the inner tube, and the nozzle of the outer tube and the tube wall of the inner tube are welded together. Matching needs and other factors, the inner diameter of the outer tube needs to be larger than the outer diameter of the inner tube, resulting in a large gap between the inner and outer tubes, causing inconvenience in welding, if the welding is not good, it is easy to cause liquid leakage during use, cause danger; also cause unsightly appearance

[0003] We have specially developed a tube shrinking device, which can be seen in the patent application publication of the applicant with the patent application number of "CN201010600472.2" and the title of the invention "a tube shrinking device", but the rotation of this device is manual. Rotation is not convenient, the labor intensity of workers is high, and the degree of mechanization is not high
