Description

Technical Field

[0001] This invention relates to the damping sleeve manufacturing industry, specifically to a slotting and shaping equipment and its process method for damping sleeve production. Background Technology

[0002] Hard polymer materials such as FEP (fluorinated ethylene propylene copolymer), PFA (tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer), PEEK (polyether ether ketone), and PI (polyimide) possess excellent wear resistance, low coefficient of friction, high hardness, and good rigidity, making them suitable for applications with stringent wear resistance requirements. Damping sleeves are one of the important applications in this field. Damping sleeves are manufactured by cutting a straight, serrated, or other shaped slit along the axial direction of the sleeve. In application, the damping sleeve is fitted into a running rod of a similar diameter to achieve vibration reduction and noise reduction, and it is widely used in fields such as medical equipment.

[0003] When producing damping sleeves, it is necessary to shape and open the slots. The existing damping sleeve production scheme has the following defects: (1) During baking and shaping, the heating is uneven, which affects the shaping and subsequent slot opening quality; (2) The slot opening angle is offset, which causes the finished product to have overlapping slots, resulting in excessive resistance and damping failure; (3) The slot opening gap is too large, which affects the vibration reduction and noise reduction effect. It is urgent to develop a slot opening and shaping equipment and its process method for damping sleeve production. Summary of the Invention

[0010] A sleeve fixing assembly, wherein the sleeve fixing assembly is internally connected to the heating box assembly;

[0011] A slit-opening device, which is connected to the top of the heating chamber assembly;

[0012] The sleeve fixing assembly includes:

[0013] The drive unit is connected to the interior of the heating oven assembly;

[0014] A positioning disk assembly, which is connected to a drive device, is used to fix the sleeve.

The blade holder 706 slits along the slot of the stainless steel needle 605. After the slit of the previous sleeve is completed, the sleeves are collected uniformly.

[0044] The working principle of this invention is as follows: A slot (not shown in the figure) is provided on the top of the outer casing 201. Under the drive of the drive device 5, the positioning disk assembly 6 is moved out of the top of the outer casing 201, and several sleeves are connected to the positioning disk assembly 6. Then, the positioning disk assembly 6 and the externally fixed sleeves are moved into the top compartment 202. The positioning disk assembly 6 rotates axially, and the sleeves are evenly baked through several first heating elements 203 and bottom auxiliary heating elements 3. After baking, the sleeves can be cooled by air by the blower 206. When the first drive element 302 runs, it cooperates with the rack and pinion 306. The sleeve 304 can be moved horizontally along the direction of the limiting rod 303. When the second heating element 305 moves to the bottom of the positioning plate assembly 6, it can cooperate with several first heating elements 203 to further improve the baking uniformity of the sleeve.

The third drive unit 601 is not limited to an electric telescopic rod; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can achieve longitudinal height adjustment of the disc frame 604. No specific limitation is made here. The fourth drive unit 606 is not limited to an electric telescopic rod; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can cooperate with the ball 602 to achieve swing adjustment of the disc frame 604. No specific limitation is made here. A groove (not shown in the figure) is provided for facilitating the slit opening. After the sleeve is baked and cooled, the second drive member 502 drives the plate frame 604 to rise to a set height position on the outside of the top of the outer box 201, and then rotates it one by one to the outside of the foam cotton rod 703. Under the drive of the fifth drive member 701 and the sixth drive member 702, the foam cotton rod 703 is driven to press against the outer wall of the sleeve. The seventh drive member 704 drives the blade holder 706 to move down and abut against the outside of the sleeve. Under the drive of the eighth drive member 707, the blade holder 706 is driven to move horizontally to complete the slit opening process of the sleeve. The sixth drive member 702, the seventh drive member 704 and the eighth drive member 707 are not limited to electric telescopic rods. Linear motors, electric cylinders or pneumatic cylinders can also be used, as long as the movement and adjustment of the foam cotton rod 703, the fixed plate frame 705 and the blade holder 706 can be realized. No specific limitation is made here.

[0046] In summary, this device is reasonably designed and highly automated, enabling uniform baking and cooling of several sleeves. The sleeves are heated evenly, further improving the shaping quality and subsequent slit-opening quality of the sleeves, making it suitable for widespread use.
