Technical Field

[0001] The utility model relates to a novel hard pipe loose coil winding device, which is mainly used for winding hard copper and aluminum pipes and belongs to the technical field of non-ferrous metal pipe processing equipment. Background Art

[0002] In the prior art, the winding devices for hard copper and aluminum pipes mainly adopt a host cantilever structure. For the cantilever structure, the horizontal discharging, the upper and lower discharging and the discharging adopt a double-layer lifting bearing platform structure. Its deficiencies are as follows: 1. The main shaft and the winding frame are installed on the double-layer cantilever platform, and the lifting of the winding and discharging is realized through 2 groups of guide columns and lead screws. When it operates, the overall stability is poor, the winding speed is limited and the efficiency is low; 2. The equipment is huge and the foundation is deep. For example, the Chinese patent publication number CN220392741U discloses a lifting device of a novel rewinder, in which the machine base of the rewinder is cantilever-mounted on the guide column. Content of the Utility Model

[0007] As an improvement of the utility model, a pair of parallel vertical guide rails are further provided. The main shaft bracket is slidably installed on the vertical guide rails, and a nut is fixedly connected to the main shaft bracket; the main shaft lifting device includes a single ball screw and a lifting servo control motor. The lifting servo control motor drives the ball screw to rotate, and the ball screw passes through the nut on the main shaft bracket.

[0008] As an improvement of the utility model, the main speed reducer mainly consists of a gearbox and a main speed reducer motor. The gearbox is a two-stage transmission gearbox with spiral bevel gears and spur cylindrical gears in cooperation. The main speed reducer motor is a main speed reducer motor using a servo control motor. The output shaft of the gearbox is a hollow shaft, and the guide frame assembly is fixedly installed on the hollow shaft through an expansion sleeve. The main speed reducer drives the guide frame assembly and the main shaft assembly to rotate synchronously.

[0009] As an improvement of the utility model, the guide frame assembly includes a guide rod seat, an outer guide rod, an inner guide rod, an outer pressure ring and an inner pressure ring. The guide rod seat and the outer pressure ring are connected by the outer guide rod, and the guide rod seat and the inner pressure ring are connected by the inner guide rod.

The linear guides are arranged in parallel and symmetrically, changing the problems of high machining accuracy and poor installation and maintenance process caused by the original opposed arrangement, making the mechanical structure more reasonable, reducing the process difficulty and manufacturing cost of equipment manufacturing, and at the same time reducing the difficulty of maintenance and support;

[0013] 3. The main shaft lifting device adopts a single-ball screw pair transmission mechanism to operate independently, greatly simplifying the lifting mechanism, and significantly improving the transmission efficiency of the ball screw, with a more reasonable structure, stable and reliable operation;

[0014] 4. The output shaft of the main speed reducer is a hollow shaft, enabling the main shaft to transmit rotational torque through a guiding long key and also providing space for the main shaft to move up and down;

[0015] 5. For the two-stage transmission gearbox with a specific structure, the motor is directly connected to the input end of the reducer, simplifying the structure of the main shaft rotation transmission. Description of the Drawings
