[0029] The side support mechanism 6 is located on the side of the collet device 3 and is arranged opposite to the rolling mechanism 8. It is installed on the two parallel slide rails 10 provided on the top surface of the cabinet 1. The side support mechanism 6 functions to support the product from the other side during the rolling process, forming a three-point support to prevent the product from deforming due to uneven stress. The side support mechanism 6 includes a support arm 61 and a support head 62. The support head 62 includes two wheel-shaped support heads 62 installed side by side at the top end of the support arm 61.

[0031] The rotary closing semi-automatic machine is also equipped with a perfect control system, including a PLC controller, a touch screen human-machine interface and a safety interlocking device. The control system is electrically connected with other mechanisms and realizes the coordinated movement of the mechanisms, and has the functions of fault diagnosis, parameter memory and storage of various product process parameters, which facilitates the operator to quickly switch the production of different products. The technology belongs to the conventional technology and is not shown in the drawings.

[0032] The working principle and method of the above rotary closing semi-automatic machine are as follows:

[0033] Firstly, the operator puts the assembled semi-finished product into the collet device 3. The semi-finished product includes the inner core, spring, sealing steel ball, sealing ring and counter-inserted air nozzle and other components which have been assembled. The operator needs to ensure that the semi-finished product is placed in the correct position and the components are assembled in place.

[0034] Secondly, the operator presses the start switch with both hands to trigger the equipment to run. After starting, the collet device 3 automatically clamps the product, and the clamping force is controlled by the preset parameters to ensure that the product is firmly fixed without deformation.

[0035] Thirdly, the pressing mechanism 5 automatically descends to apply pressure to the top of the product to ensure that the assembled parts will not be displaced during the rotation and rolling process. After the pressing mechanism 5 is pressed into place, the control system detects whether the pressing position is correct. If it is correct, the next step is entered, otherwise an alarm is issued and the machine is stopped.

[0036] Fourthly, the side support cylinder 7 automatically starts to push the side support mechanism 6 out to support the product from the position opposite to the rolling mechanism 8. This step forms three-point support during the product processing process, which is the bottom support of the collet device 3, the top support of the pressing mechanism 5 and the side support of the side support mechanism 6, effectively preventing the product from deforming due to uneven stress during the rolling process.

[0037] Step 5, the control system starts the chuck rotation motor 4, driving the chuck device 3 and the product inside it to start rotating. The chuck rotation motor 4 automatically adjusts the speed to the optimal value according to the characteristics of the product, ensuring the consistency of the rolling effect. The control of the rotation speed is a key factor affecting the quality of the product. Too fast may lead to insufficient rolling, and too slow will affect the production efficiency.

[0038] Step 6, the rolling cylinder 9 is started, driving the rolling mechanism 8 to move towards the product. When the rolling mechanism 8 contacts the product, it starts to roll and form the side of the product. The rolling depth and pressure are precisely controlled by the control system to ensure that the product meets the requirements. During the entire rolling process, the product is always rotating, ensuring uniform rolling.

[0039] Step 7, after rolling is completed, the control system controls each mechanism to reset according to the predetermined program: first, stop the rolling cylinder 9 and retract the rolling mechanism 8; then retract the side support cylinder 7 and the side support mechanism 6; then lift the lower pressing mechanism 5; finally, stop the chuck rotation motor 4 and automatically release the chuck device 3.

[0040] Step 8, after the equipment is completely stopped, the operator takes out the finished product and puts the next assembled semi-finished product into the chuck device 3, repeating the above steps to continue production.

[0041] The above is only the preferred embodiment of the invention, and is not a limitation on the scope of protection of the invention. Any innovative improvement or replacement based on the invention should fall within the scope of the invention. At the same time, the parameters, materials and processes mentioned in the above embodiment are not unique. Without departing from the technical essence of the invention, those skilled in the art can make various alternative choices, which should be considered as falling within the scope of protection of the invention.
