[0015] Refer to Figs. 1 to 4 The embodiment of the utility model is further explained.

[0016] A thin-walled graphite copper sleeve special tray, comprising a tray body 100, the tray body 100 is provided with a shaping rod 1 matched with a thin-walled graphite copper sleeve 200, the shaping rod 1 is composed of invar alloy, so as to avoid the problem that the copper expansion coefficient of the shaping rod 1 material and the copper expansion coefficient of the copper sleeve are not matched, causing the copper sleeve inner hole to be stuck after drying and cooling, the tray body 100 is provided with a fixing part 2 for fixing shaping rods 1 of different diameters, the diameter of the shaping rod 1 is slightly smaller than the inner diameter of the thin-walled graphite copper sleeve 200, so as to facilitate the thin-walled graphite copper sleeve 200 to be sleeved on the shaping rod 1, the shaping rod 1 comprises a flow-through cavity 3, a plurality of air holes 4 are formed on the inner wall of the flow-through cavity 3, so as to avoid the problem that the shaping rod 1 is a solid rod and blocks the inner hole of the copper sleeve, causing the adhesive solvent to remain.

[0017] When drying, the thin-walled graphite copper sleeve 200 is placed on the shaping rod 1 of the tray body 100, and then the tray is transferred to the layered support in the drying oven for subsequent drying. During drying, the thin-walled graphite copper sleeve 200 is shaped by the shaping rod 1 on the special tray to avoid deformation of the copper sleeve, which would reduce the yield rate. Since the diameter of the shaping rod 1 is slightly smaller than the inner diameter of the thin-walled graphite copper sleeve 200, the thin-walled graphite copper sleeve 200 can be smoothly fitted and tightly adhered to the shaping rod. On the surface of rod 1, since the shaping rod 1 is made of Invar alloy, the coefficient of thermal expansion of the shaping rod 1 is close to that of the copper sleeve, which avoids the problem of the copper sleeve getting stuck after cooling due to the mismatch of the material expansion coefficients. At the same time, the design of the flow chamber 3 and the air hole 4 of the shaping rod 1 facilitates the escape of the adhesive solvent vapor on the solid lubricant from the inner hole of the thin-walled graphite copper sleeve 200 during the drying process, reducing the amount of adhesive solvent remaining in the inner hole of the thin-walled graphite copper sleeve 200 during the drying process.

[0018] The fixing part 2 includes a positioning plate 21, a spring 22, and a stop rod 23. The positioning plate 21 includes a positioning groove 211 that is inserted into the shaping rod 1 and a plurality of receiving grooves 212 connected to the positioning groove 211. The plurality of receiving grooves 212 are arranged around the shaping rod 1. Each receiving groove 212 group includes two receiving grooves 212. The number of springs 22 and the number of stop rods 23 are set to correspond to the number of receiving grooves 212. One spring 22 is installed in one receiving groove 212. The spring 22 is movably connected to the corresponding receiving groove 212. The end of the stop rod 23 extends out of the corresponding receiving groove 212 and abuts against the outer surface of the bottom of the shaping rod 1. The end of the stop rod 23 is arc-shaped, so that when the shaping rod 1 is inserted into the positioning groove 211, the stop rod 23 can slide smoothly on the shaping rod 1 and abut against it, so that the shaping rod 1 can continue to penetrate deeper into the positioning groove 211.

[0019] The positioning groove 211 on the positioning plate 21 is used to insert the shaping rod 1. When the shaping rod 1 is inserted into the positioning groove 211, it abuts against the end of the abutment rod 23. The abutment rod 23 compresses the spring 22, generating a force that acts on the abutment rod 23, allowing the abutment rod 23 to tightly abut against the outer surface of the bottom of the shaping rod 1. Thus, the abutment rods 23 in the multiple receiving grooves 212 cooperate to firmly fix the shaping rod 1 onto the positioning plate 21. Different diameter shaping rods 1 result in different degrees of compression of the adjusting spring 22, facilitating the abutment rod 23 to abut against shaping rods 1 of different diameters and fix them onto the positioning plate 21. This allows the special tray to install shaping rods 1 of different diameters through the fixing part 2, making it suitable for drying thin-walled graphite copper sleeves 200 of different diameters, improving the adaptability of the special tray and increasing its practicality.

[0020] The surface of the sizing rod 1 is coated with a Teflon coating, so as to reduce the friction of the thin-walled graphite copper sleeve 200 when sleeving and taking out the sizing rod 1, make the thin-walled graphite copper sleeve 200 more smoothly in the sleeving and taking out operation, meanwhile, prevent the copper sleeve inner surface from being scratched or worn in the process of contacting with the sizing rod 1, and be beneficial to improving the product yield, and the Teflon coating has excellent anti-sticking performance, can prevent the adhesive or other substances from remaining on the surface of the sizing rod 1, and the high-temperature resistance of the Teflon coating enables the Teflon coating to withstand high temperature in the drying process without decomposition, so that the sizing rod 1 keeps the low-friction and anti-sticking properties of the surface.
