Description

Technical Field

[0001] This application relates to the field of thermos cup processing technology, and in particular to a cup body thread forming device. Background Technology

[0002] Traditional cup thread forming processes typically employ machining methods such as turning or rolling. These traditional methods often require the cup to be tilted to accommodate the angle of the cutting tool or mold, which not only limits production efficiency but also easily leads to problems such as low thread accuracy and poor surface quality. This is especially true for products with high precision requirements, such as stainless steel insulated cups and aluminum sports water bottles, where traditional processing methods struggle to meet their stringent dimensional and appearance standards. Furthermore, the complexity of operation and the difficulty of equipment adjustment increase costs and the workload for workers.

[0003] As market demands for product quality and production efficiency continue to rise, existing technologies can no longer fully meet these needs. In particular, there are significant shortcomings in terms of automation, processing precision, and flexibility in adapting to different product specifications. Therefore, developing a cup-body thread forming machine that can achieve high precision, high efficiency, and ease of operation has become an urgent need for the industry.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0042] The working principle and process are as follows.

[0043] Preparation:

[0044] The lower end of the cup body 90 to be processed is clamped and fixed on the cup body positioning base 20. Multiple cup body positioning bases 20 are arranged in a row through the transmission belt 21 to achieve continuous production.

[0045] Ensure that the cup body 90 to be processed is perpendicular to the working reference plane, and adjust the position of the cup body positioning base 20 so that the cup body axis is perpendicular to the horizontal plane.

[0046] Start processing:

[0047] Positioning and calibration: After the sensor detects the 90° position of the cup to be processed and ensures that it is correct, the first servo control system and the second servo control system are started.

[0048] Feeding and contact: The first servo control system controls the inner pressure roller fixing seat 30 to move, so that the inner pressure roller 50 extends into the cup mouth of the cup body 90 to be processed and fits against the inner wall of the cup body; at the same time, the second servo control system controls the outer pressure plate fixing seat 40 to move, so that the starting point of the straight groove 61 on the outer pressure plate 60 is close to the outer wall of the cup body 90 to be processed.

[0049] Synchronous extrusion molding: The power transmission mechanism is started, and the fifth servo motor 56 transmits rotational force to the inner pressure roller 50 through the universal transmission rod 57 and the gear set 58, causing it to rotate; at the same time, the second servo control system controls the outer pressure plate 60 to move along a predetermined trajectory, so that the spiral protrusion 51 of the inner pressure roller 50 and the straight groove 61 of the outer pressure plate 60 correspond exactly from the starting point to the ending point. During this process, the outer pressure plate 60 is simultaneously raised or offset, so that the cup body 90 to be processed forms a non-uniform height thread.

[0050] Completion and Reset: After processing is completed, the servo system is reset, the finished cup body 90 is removed, and preparation is made for the next processing cycle.
