Heat the heat treatment pit furnace to 65℃~70℃ and keep it warm for 48h; Step 2: placing the cathode roller 500 hung out of the furnace on the heat preservation unit 100 for heat preservation treatment; Step 3: regulating and locking, controlling the distance between the heat preservation unit 100 and the cathode roller 500 by the regulating unit 200, and performing a locking operation by the locking unit 300; The heat preservation unit 100 includes a roller mill base plate 101, a pair of slide rails 1031 are installed on the roller mill base plate 101, a slide seat 103 is slidably arranged on the pair of slide rails 1031, a heat preservation cover 104 is installed on the slide seat 103, a heating plate 1043 is installed inside the heat preservation cover 104, and the arc surface of the heat preservation cover 104 is aligned with the cathode roller 500; The control unit 200 includes a positioning cover 201, which is movably plugged into the side wall of the heat preservation cover 104, and the side wall of the positioning cover 201 is engraved with a scale line 2012, a feed bolt 2011 is rotatably installed inside the positioning cover 201, and the feed bolt 2011 is rotatably connected to the side wall of the heat preservation cover 104, and a push rod 202 is inserted inside the positioning cover 201, and an L-shaped push plate 203 is installed at the bottom of the push rod 202, and the L-shaped push plate 203 is connected to the positioning cover 201. 01 corresponds to the flip plate 2031 installed at the bottom, and the end of the L-shaped push plate 203 contacts the inclined surface 2032 opened on the flip plate 2031, the bottom of the flip plate 2031 is overlapped with a pressure block 204, and the bottom of the pressure block 204 is installed with a pressure rod 2042; wherein the feed bolt 2011 in the control unit 200 drives the positioning cover 201 to move, and the scale line 2012 shows the distance between the heat preservation cover 104 and the cathode roller 500, and then through the slide 1 03 drives the heat preservation cover 104 to slide. During the movement of the heat preservation cover 104, after the push rod 202 on the heat preservation cover 104 contacts with the cathode roller 500, the push rod 202 shrinks inward until the push rod 202 can no longer move. At this time, the distance from the heat preservation cover 104 to the side wall of the cathode roller 500 is the required distance, wherein the size of the distance mainly depends on the initial position of the positioning cover 201. In this way, the distance can be accurately controlled, thereby making the operation simpler.

During the rotation of the seesaw 301, the contact point of the squeezing rod 2042 on the seesaw 301 changes. When the extension line of the squeezing rod 3031 and the pressure rod 2042 are both on one side of the seesaw, the force of the squeezing spring 3033 pushing the squeezing rod 3031 will drive the end of the squeezing rod 3031 to move toward the side of the pressure rod 2042, and then push the entire seesaw 301 to rotate, so that the locking plate 3012 at the other end of the seesaw 301 is stuck in the block, so that the forward path of the slide 103 is locked at this time, thereby ensuring that the entire insulation cover 104 is in a locked state, ensuring that the distance between the insulation cover 104 and the side wall of the cathode roller 500 does not change, and making the heating temperature more uniform.

Then the operator needs to rotate the handle 1053, and the rocker arm 1052 is driven to rotate by the handle 1053, and the rocker arm 1052 drives the screw shaft 105 to rotate, and the slide seat 103 on the screw shaft 105 slides on the slide rail 1031 at this time, and then the slide seat 103 as a whole drives the heat preservation cover 104 to slide toward the cathode roller 500 side.

When the top rod 202 and the top plate 2021 of the side wall of the heat preservation cover 104 contact the cathode roller 500, the top rod 202 and the top plate 2021 are squeezed, and the top rod 202 drives the baffle 2022 to slide inside the positioning cover 201, squeezing the positioning spring 2023, and the positioning spring 2023 facilitates the subsequent resetting operation.

Example 3

[0031] The difference between the above embodiment and this embodiment is that: Figures 1 to 10 As shown, a synchronous shaft 3013 is installed at the rotation center of the seesaw 301, and the synchronous shaft 3013 rotates on the inner wall of the installation port 1032.

[0032] like Figures 1 to 10As shown, in a specific embodiment, a transmission shaft 3036 is installed at the rotation center of the extrusion cover 303, and the transmission shaft 3036 movably penetrates the side wall of the heat preservation cover 104.

When the extrusion slider 3034 moves to the left side of the synchronous shaft 3013 during the sliding, the extrusion spring 3033 pushes the partition 3032 to slide, and the partition 3032 drives the extrusion rod 3031 to move downward, but this At this time, the squeezing force of the squeezing rod 3031 on the seesaw 301 changes. At this time, the squeezing force acts on the left side of the synchronous shaft 3013 as the squeezing slider 3034 moves, and finally pushes the whole seesaw 301 to rotate counterclockwise, so that the locking plate 3012 at the other end of the seesaw 301 is clamped in the clamping block 3021, so that the forward path of the slide 103 is locked at this time, thereby ensuring that the entire insulation cover 104 is in a locked state, ensuring that the distance between the insulation cover 104 and the side wall of the cathode roller 500 does not change, and making the heating temperature more uniform. Guide rods 4021 are installed at both ends of the flat plate 402, and the outer wall of the guide rod 4021 is plugged with a guide sleeve 4022, and the guide sleeve 4022 is welded on the grinding roller base plate 101. The operator can rotate the unlocking arm 3037 to drive the connected transmission shaft 3036 to rotate, and rotate the extrusion cover 303 and the extrusion rod 3031 to a certain angle, so that the locking plate 3012 and the block 3021 are separated, thereby unlocking the locking operation and facilitating later resetting.

[0033] The implementation principle of a cathode roller hot processing method of this embodiment is as follows: Wrap the shaft heads at both ends of the cathode roller 500 with heat-insulating cotton and fix them with iron wire, perform heat insulation treatment on the mounting parts on the shaft heads, and then hang the cathode roller vertically in a heat treatment pit furnace, heat the heat treatment pit furnace to 65℃~70℃, and keep it warm for 48h; The cathode roller 500 hanging out of the furnace is placed on the heat preservation unit 100 for heat preservation treatment; The rotation center of the cathode roller 500 is mounted on the lower bearing seat 1021.

[0034] Then the operator turns the feed bolt 2011, and the feed bolt 2011 drives the positioning cover 201 to slide inside the heat preservation cover 104. The positioning cover 201 can slide out from the heat preservation cover 104, and the scale line 2012 on the positioning cover 201 can show the sliding distance. At this time, the data shown by the scale line 2012 is the preset distance from the heat preservation cover 104 to the cathode roller 500.

[0035] Then the operator needs to turn the handle 1053, which drives the rocker arm 1052 to rotate, and the rocker arm 1052 drives the screw shaft 105 to rotate. The slide 103 on the screw shaft 105 slides on the slide rail 1031 at this time, and then the slide 103 as a whole drives the insulation cover 104 to slide toward the cathode roller 500. The cathode roller 500 can be heated by the heating plate 1043 inside the insulation cover 104.

[0036] When the top rod 202 and the top plate 2021 of the side wall of the heat preservation cover 104 contact the cathode roller 500, the top rod 202 and the top plate 2021 are squeezed, and the top rod 202 drives the baffle 2022 to slide inside the positioning cover 201, squeezing the positioning spring 2023, and the positioning spring 2023 facilitates the subsequent resetting operation.

[0037] Until the top plate 2021 contacts the end surface of the positioning cover 201, the top rod 202 will not be able to move, and the distance between the heat-insulating cover 104 and the surface of the cathode roller 500 is the required distance.

[0038] However, during the movement of the push rod 202, the L-shaped push plate 203 at the bottom of the push rod 202 can slide inside the installation groove 2013, and the L-shaped push plate 203 squeezes the flip plate 2031 that is rotatably installed inside the installation groove 2013, and the inclined surface 2032 on the flip plate 2031 drives the flip plate 2031 to rotate. When the flip plate 2031 rotates, it can drive the torsion spring 2033 to rotate, and the torsion spring 2033 is used to facilitate the subsequent resetting operation.

[0039] After flipping, the flip plate 2031 can drive the bottom pressure block 204, the synchronous plate 2041 and the pressure rod 2042 to press downward, and the synchronous plate 2041 slides downward along the limit rod 2043 at this time, and the limit spring 2045 on the limit rod 2043 is compressed synchronously, and the limit spring 2045 is used to facilitate the subsequent resetting operation.

[0040] When the pressing rod 2042 moves downward, the pressing rod 2042 presses the left side of the seesaw 301 (with Fig. 9As a reference), the seesaw 301 rotates, and during the rotation of the seesaw 301, the horizontal position of the extrusion slider 3034 changes, so the extrusion slider 3034 drives the extrusion rod 2042 to rotate, and the extrusion rod 2042 drives the extrusion slider 3034 to slide on the extrusion slot 3035. When the extrusion slider 3034 moves to the left side of the synchronous shaft 3013 during the sliding, the extrusion spring 3033 pushes the partition 3032 to slide, and the partition 3032 drives the extrusion rod 3031 to move downward, but this At this time, the extrusion pressure of the extrusion rod 3031 on the seesaw 301 changes. At this time, the extrusion pressure acts on the left side of the synchronization shaft 3013 as the extrusion slider 3034 moves, and finally pushes the entire seesaw 301 to rotate counterclockwise, so that the locking plate 3012 at the other end of the seesaw 301 is engaged in the block 3021, and the forward path of the slide 103 is locked at this time, thereby ensuring that the entire insulation cover 104 is in a locked state, ensuring that the distance between the insulation cover 104 and the side wall of the cathode roller 500 does not change, and making the heating temperature more uniform.

[0041] When the extrusion rod 3031 moves, the angle of the entire extrusion rod 3031 and the extrusion cover 303 changes, and the transmission shaft 3036 on the extrusion cover 303 rotates synchronously, causing the angle of the unlocking arm 3037 connected to it to change. Therefore, when resetting later, the operator needs to rotate the unlocking arm 3037 to drive the connected transmission shaft 3036 to rotate, and rotate the extrusion cover 303 and the extrusion rod 3031 to a certain angle, so that the locking plate 3012 and the block 3021 are separated, thereby unlocking the locking operation, which is convenient for resetting later.

[0042] During the rotation of the seesaw 301, the synchronous shaft 3013 of the seesaw 301 starts to rotate, and the synchronous shaft 3013 drives the rotating shaft 4011 to rotate, and the pressure handle 401 at the end of the rotating shaft 4011 rotates, and the sliding bar 4012 on the pressure handle 401 slides upward, and the sliding bar 4012 drives the flat plate 402 to move upward, and the guide rod 4021 on the flat plate 402 slides inside the guide sleeve 4022, which can play a guiding role. The flat plate 402 drives the calibration adjustment block 403 to slide upward, and the inclined surface of the calibration adjustment block 403 squeezes the cathode roller 500 to move toward the center, ensuring that the roller surface of the cathode roller is in the center position, which is convenient for subsequent processing. After the cathode roller 500 is adjusted, the upper bearing seat 1022 and the lower bearing seat 1021 are installed to locate the position of the cathode roller 500.

[0043] Then install the above device in the roller grinding machine, and then use the roller grinding machine to perform preliminary processing on the cathode roller. First, it is necessary to ensure that the center of the cathode roller 500 is parallel to the center of the machine tool guide rail, open the cutting fluid control valve to control the cutting fluid outlet temperature to 65±10℃, and then perform roller grinding. During the processing, the rough turning roller surface size leaves a fine processing allowance of 0.1~0.2mm, and the speed of the roller grinding machine for rough turning operation is 10~15r / min, and the feed rate is 2mm / r. A large feed rate is used for cutting to shorten the cutting time and reduce the temperature loss of the roller body. The speed of the roller grinding machine for fine turning operation is 10~15r / min, and the feed rate is 1mm / r. A large feed rate is used for cutting to shorten the cutting time and reduce the temperature loss of the roller body. A circular turning tool is used for cutting to reduce the peak and valley difference of the turning tool pattern, effectively shorten the grinding time to eliminate the turning tool pattern, and improve the processing efficiency. In addition, during the roller turning process, it is necessary to measure the roller surface diameter and straightness to monitor the roller surface processing status. After processing, the surface is roughly ground in sequence using 40-mesh polishing wheels, 60-mesh polishing wheels, and 80-mesh polishing wheels to eliminate turning tool marks and finally complete the production operation.
