[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0022] like Figure 2 to Figure 6As shown, the nickel cylinder disassembly and assembly tool in the wire drawing machine described in the utility model includes: a base 2, a first fixed sleeve 3, a second fixed sleeve 4 and a movable sleeve 5. The base 2, the first fixed sleeve 3, the second fixed sleeve 4 and the movable sleeve 5 are all made of copper material. In this way, the first fixed sleeve 3 and the second fixed sleeve 4 can prevent the copper sleeve 1 from being damaged due to the harder material when positioning the copper sleeve 1, and the movable sleeve 5 can also prevent the nickel belt sleeve 11 from being damaged due to the harder material when pushing the nickel belt sleeve 11. The outer diameters of the first fixed sleeve 3 and the second fixed sleeve 4 are the same, and are both 0.2mm to 0.3mm smaller than the outer diameter of the nickel cylinder copper sleeve. Positioning grooves 21 are provided on the upper and lower end walls of the base 2. The positioning grooves 21 are adapted to the first fixed sleeve 3 and the second fixed sleeve 4, and chamfers are provided on the inner walls of the positioning grooves 21.

[0023] A first step groove 31 is provided on the upper end wall of the first fixed sleeve 3, a first length H1 between the lower end wall of the first fixed sleeve 3 and the first step groove 31 is greater than the length of the nickel tube nickel belt sleeve, a chamfer is provided between the lower end wall and the outer side wall of the first fixed sleeve 3, a second step groove 41 is provided on the upper end wall of the second fixed sleeve 4, the overall height of the second fixed sleeve 4 is 1 / 3 to 1 / 4 of the overall height of the first fixed sleeve 1, so that the first fixed sleeve 3 and the second fixed sleeve 4 can be easily distinguished, a chamfer is also provided between the lower end wall and the outer side wall of the second fixed sleeve 4, and the inner diameters of the first step groove 31 and the second step groove 41 are adapted to the inner diameters of the ends of the nickel tube copper sleeve.

[0024] The upper end wall, the lower end wall and the inner side wall of the movable sleeve 5 are at right angles. Four screw holes are evenly distributed on the circumference of the outer side wall of the movable sleeve 5. Handles 51 made of copper material are threadedly connected in the screw holes. The four handles 51 are symmetrical in pairs. Locking nuts 52 are threadedly connected to the threaded sections of the handles 51. The locking nuts 52 are tightened and pressed against the outer side wall of the movable sleeve 5 to play a locking role. A bakelite ball 53 is threadedly connected to the handle 51.

[0025] When it is necessary to install the nickel belt sleeve 11 on the copper sleeve 1, Figure 7As shown, the base 2 is placed on a flat ground. Since both the upper end wall and the lower end wall of the base 2 have positioning grooves 21, no matter which end wall of the base 2 faces upward, it will not affect the installation with the second fixing sleeve 4. Then, the lower end of the second fixing sleeve 4 is inserted into the positioning groove 21 of the base 2. The chamfer in the positioning groove 21 and the chamfer on the lower end wall of the second fixing sleeve 4 cooperate to play a guiding role to prevent interference and collision between the second fixing sleeve 4 and the positioning groove 21 when the second fixing sleeve 4 is inserted into the positioning groove 21. The nickel belt sleeve 11 is mounted on the first fixing sleeve 3. Since the outer diameter of the first fixing sleeve 3 is 0.2mm~0.3mm smaller than the outer diameter of the copper sleeve 1, and the inner diameter of the nickel belt sleeve 11 is larger than the outer diameter of the copper sleeve 1, the nickel belt sleeve 11 is The belt sleeve 111 can be smoothly mounted on the first fixed sleeve 3 and a large movable gap can be left between the first fixed sleeve 3, and then the lower end of the copper sleeve 1 is inserted into the second step groove 41 of the second fixed sleeve 4, and the first step groove 31 on the first fixed sleeve 3 is inserted into the upper end of the copper sleeve 1. At this time, the lower end wall of the first fixed sleeve 3 is located at the top, and the first fixed sleeve 3, the copper sleeve 1 and the second fixed sleeve 4 are coaxially aligned. The nickel belt sleeve 11 will first drop and rest on the copper sleeve 1 under the action of gravity. The first length H1 between the lower end wall of the first fixed sleeve 3 and the first step groove 31 is greater than the length of the nickel belt sleeve 11. The nickel belt sleeve 11 drops again under gravity and rests on the copper sleeve 1. The nickel belt sleeve 11 and the copper sleeve 1 are also coaxially aligned. A section of the fixed sleeve 3 that is not covered by the nickel belt sleeve 11 will be exposed, and then the movable sleeve 5 is mounted on the first fixed sleeve 3. Since there is a chamfer between the lower end wall and the outer side wall of the first fixed sleeve 3 located at the top, the chamfer guides the movable sleeve 5 to prevent interference and collision between the movable sleeve 5 and the first fixed sleeve 3. When the movable sleeve 5 is mounted on the first fixed sleeve 3, the movable sleeve 5 will abut against the nickel belt sleeve 11. Since the inner side wall and the end wall of the movable sleeve 5 are at a right angle, there is enough contact surface between the end wall of the movable sleeve 5 located at the bottom and the nickel belt sleeve 11. The movable sleeve 5 will not cause damage to the end of the nickel belt sleeve 11 when pushing the nickel belt sleeve 11. Then the staff simultaneously holds two symmetrical handles 51 in the four grips 51. The handles 51 apply downward pressure to make the movable sleeve 5 push the nickel belt sleeve 11 downward. The symmetrical two sides of the nickel belt sleeve 11 are subjected to the same force and can move vertically downward along the first fixed sleeve 3 to the copper sleeve 1. Since there is a matching tolerance between the copper sleeve 1 and the nickel belt sleeve 11, the nickel belt sleeve 11 can be smoothly sleeved on the copper sleeve 1 under the pushing of the movable sleeve 5 until the nickel belt sleeve 11 is completely sleeved on the copper sleeve 1. In the process of pushing the movable sleeve 5, it is necessary to hold the two symmetrical handles 51 in turn to apply pressure downward, that is, first hold the two symmetrical handles 51 for pressure, and then hold the two symmetrical handles 51 for pressure. In this way, it can be ensured that the movable sleeve 5 can evenly transfer the pushing force to the nickel belt sleeve 11, thereby improving the installation speed of the nickel belt sleeve 11.This assembly method can keep the nickel belt sleeve 11 and the copper sleeve 1 coaxially aligned by positioning and guiding the nickel belt sleeve 11 through the first fixed sleeve 3, and then use the movable sleeve 5 to apply a uniform thrust to the nickel belt sleeve 11 so that the nickel belt sleeve 11 can be quickly sleeved on the copper sleeve 1.

[0026] When it is necessary to remove the nickel belt sleeve 11 on the nickel cylinder from the copper sleeve 1, as shown in FIG. Figure 8 As shown, the lower end of the first fixed sleeve 3 is inserted into the positioning groove 21 of the base 2, and the second length H2 between the first step groove 31 of the first fixed sleeve 3 and the upper end wall of the base 2 is greater than the length of the nickel belt sleeve 11. Then, the copper sleeve 1 with the nickel belt sleeve 11 is inserted into the first step groove 31, and then the second step groove 41 of the second fixed sleeve 4 is inserted into the upper end of the copper sleeve 1. Then, the movable sleeve 5 is sleeved on the second fixed sleeve 4, and the handle 51 is held to repeatedly push the movable sleeve 5 downward, so that the movable sleeve 5 pushes the nickel belt sleeve 11 on the copper sleeve 1 for multiple times until the nickel belt sleeve 11 and the copper sleeve 1 are loosened, and then continue to apply downward pressure to the movable sleeve 5 to transfer the nickel belt sleeve 11 from the copper sleeve 1 to the first fixed sleeve 3. The assembly tolerance between the fixed sleeve 3 and the nickel belt sleeve 11 is relatively large. The nickel belt sleeve 11 can be smoothly mounted on the first fixed sleeve 3 under the push of the movable sleeve 5. When the nickel belt sleeve 11 drops to a certain position, the movable sleeve 5 no longer needs to move on the second fixed sleeve 4. At this time, the second fixed sleeve 4 can be detached, and the movable sleeve 5 moves on the copper sleeve 1. Since the length between the first step groove 31 of the first fixed sleeve 3 and the upper end wall of the base 2 is greater than the length of the copper sleeve 1, when the nickel belt sleeve 11 is completely mounted on the first fixed sleeve 3, there is no interference between the nickel belt sleeve 11 and the copper sleeve 1. At this time, the copper sleeve 1 can be removed for cleaning or maintenance, and then the nickel belt sleeve 11 mounted on the first fixed sleeve 3 can be removed, and the entire disassembly work is completed. This disassembly method will not cause damage to the copper sleeve 1 and the nickel belt sleeve 11, and the disassembly speed is fast.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
