Description

Technical Field

[0001] This utility model relates to the field of copper tube manufacturing equipment technology, and in particular to a device for disassembling and assembling the inverted disc of a copper tube inverted disc drawing machine. Background Technology

[0002] In the copper tube production and processing field, the inverted coil drawing machine is the core equipment for achieving continuous copper tube drawing, diameter reduction, and wall thickness increase. The inverted disc, as a key load-bearing and transmission component of this equipment, is mainly used to wind the copper tubes to be drawn or already drawn, and rotates synchronously with the main shaft through a rigid connection, providing stable tension and guidance for the copper tube drawing. Because the inverted disc is under high-speed rotation and heavy load for extended periods, its surface grooves are prone to wear and deformation, and it needs to be periodically replaced with appropriate models according to the specifications of the copper tubes produced (such as diameter and length). Therefore, the inverted disc disassembly and assembly device becomes an important auxiliary device to ensure the maintenance efficiency of the inverted coil drawing machine and maintain production continuity. Existing inverted disc disassembly and assembly devices mostly consist of a base, lifting components (such as hand-operated hoists or crane connecting brackets), and a simple support structure. By fixing the device to the coil drawing machine frame and cooperating with lifting equipment, the inverted disc can be separated and installed from the main shaft. It is an indispensable auxiliary device in the daily maintenance and repair of the inverted coil drawing machine.

[0003] During the disassembly and assembly of the inverted disc, as the operator gradually loosens the connecting bolts, the disc is suspended in mid-air the instant it separates from the main shaft. If the operator applies uneven force when adjusting the height, the suspended disc will sway from side to side. This not only makes it difficult to disassemble the remaining bolts due to the difficulty in aligning the bolt holes, but the impact generated by the swaying may also cause damage to the surrounding frame or wire drawing die. Once the disc is completely separated from the main shaft, it remains in an unsupported state throughout the entire process of being slowly lowered to the ground or transfer frame. If the hoisting equipment experiences braking delay or the chain of the hand-operated hoist jams, the disc, which has lost its stable restraint, will instantly become unbalanced and tilt, which may damage the support pad or ground facilities below, and pose a direct threat to the safety of the surrounding operators.

[0004] Therefore, a device for disassembling and assembling the inverted disc of a copper tube inverted disc pulling machine was designed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a device for disassembling and assembling the inverted disc of a copper tube inverted disc pulling machine. It solves the problem that during the disassembly and assembly of the inverted disc, it is prone to shaking due to ground vibration and uneven operating force when it is separated from the main shaft. This not only affects the disassembly of the remaining bolts but may also cause it to bump into the surrounding frame or mold.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A device for disassembling and assembling an inverted plate of a copper tube inverted coiling machine includes an inverted coiling machine body, a mounting bracket fixedly installed on the top of the inverted coiling machine body, an inverted plate disposed inside the inverted coiling machine body, a positioning component fixedly installed on the inner wall of the top of the mounting bracket, and a disassembly and assembly auxiliary component detachably installed at the bottom of the positioning component for supporting the inverted plate during disassembly and assembly; the disassembly and assembly auxiliary component provides auxiliary support during the disassembly and assembly of the inverted plate.

[0007] Preferably, a drive motor is fixedly installed on the top inner wall of the mounting bracket, and the inverted disc is detachably fixedly installed on the output shaft of the drive motor by bolts.

[0008] Preferably, at least two sets of positioning components are provided; each positioning component includes a hydraulic cylinder, the cylinder body of which is fixed to the inner wall of the top of the mounting bracket, and a connecting rod is fixedly installed at the bottom of the piston rod of the hydraulic cylinder.

[0009] Preferably, an auxiliary wheel is rotatably sleeved on the outer wall of the connecting rod, and the auxiliary wheel can rotate freely around the axis of the connecting rod; two sets of symmetrically distributed protrusions are fixedly installed on the bottom end face of the auxiliary wheel.

[0010] Preferably, a mounting post is fixedly installed at the center of the bottom end face of the auxiliary wheel, and the axis of the mounting post is collinear with the axis of the auxiliary wheel; the outer wall of the mounting post is threaded.

[0011] Preferably, the disassembly and assembly auxiliary component includes a support rod, the top end of which has a through hole adapted to the mounting post, and the support rod is slidably sleeved on the outer wall of the mounting post through the through hole; a groove is formed on the top outer wall of the support rod, and the shape and size of the groove are adapted to the protrusion.

[0012] Preferably, a nut is threaded onto the outer wall of the mounting column, and the nut is located below the support rod; at least one slot is provided on the outer wall of the nut, and the slot is provided along the radial direction of the nut.

[0013] Preferably, a mounting groove is provided on the bottom end face of the mounting column, and a fixing plug is detachably snapped into the inside of the mounting groove.

Example

[0024] Please see Figure 1-6A copper tube inverted coil drawing machine inverted plate disassembly and assembly device includes an inverted coil drawing machine body 1, a mounting frame 11 fixedly installed on the top of the inverted coil drawing machine body 1, an inverted plate 1111 disposed inside the inverted coil drawing machine body 1, a positioning component 2 fixedly installed on the inner wall of the top of the mounting frame 11, and a disassembly and assembly auxiliary component 3 detachably installed at the bottom of the positioning component 2 for supporting the inverted plate 1111 during disassembly and assembly; the positioning component 2 cooperates with the disassembly and assembly auxiliary component 3 to provide auxiliary support during the disassembly and assembly of the inverted plate 1111; a drive motor 111 is fixedly installed on the inner wall of the top of the mounting frame 11, and the inverted plate 1111 is detachably fixedly installed on the output shaft of the drive motor 111 by bolts, so as to realize the drive motor 1111 1. Upon startup, the inverted disc 1111 rotates synchronously around the output shaft axis; at least two sets of positioning components 2 are provided, and the two sets of positioning components 2 are symmetrically distributed on both sides of the output shaft axis of the drive motor 111; the positioning component 2 includes a hydraulic cylinder 21, the cylinder body of the hydraulic cylinder 21 is fixed to the inner wall of the top of the mounting bracket 11, and a connecting rod 211 is fixedly installed at the bottom of the piston rod of the hydraulic cylinder 21; an auxiliary wheel 2111 is rotatably sleeved on the outer wall of the connecting rod 211, and the auxiliary wheel 2111 can rotate freely around the axis of the connecting rod 211; two sets of symmetrically distributed protrusions 2112 are fixedly installed on the bottom end face of the auxiliary wheel 2111, and the two sets of protrusions 2112 are centrally symmetrical about the axis of the auxiliary wheel 2111; a fixed position is provided at the center of the bottom end face of the auxiliary wheel 2111. A mounting post 2113 is fixedly installed, and the axis of the mounting post 2113 is collinear with the axis of the auxiliary wheel 2111. The outer wall of the mounting post 2113 is threaded. The disassembly and assembly auxiliary component 3 includes a support rod 31. The top of the support rod 31 has a through hole adapted to the mounting post 2113, through which the support rod 31 is slidably fitted onto the outer wall of the mounting post 2113. A groove 311 is formed on the top outer wall of the support rod 31, the shape and size of which are adapted to the protrusion 2112. The positioning of the support rod 31 is achieved through the engagement of the groove 311 and the protrusion 2112. A nut 32 is threaded onto the outer wall of the mounting post 2113, located below the support rod 31. Tightening the nut 32 can press the support rod 31 down. The nut 32 is fixed at a preset height position on the mounting post 2113. At least one slot 321 is provided on the outer wall of the nut 32. The slot 321 is a T-shaped design composed of two rectangles and is opened along the radial direction of the nut 32. A mounting groove 2114 is provided on the bottom end face of the mounting post 2113. The axis of the mounting groove 2114 is collinear with the axis of the mounting post 2113. A fixing plug 33 is detachably and snap-fitted into the interior of the mounting groove 2114. The fixing plug 33 includes a pin 331 adapted to the mounting groove 2114, which is snap-fitted into the mounting groove 2114. An anti-slip rubber coating is provided on the outer wall of the pin 331 to increase the friction between the pin 331 and the inner wall of the mounting groove 2114.At least one locking block 332 is hinged to the outer wall of the pin 331 of the fixing plug 33. The top of the locking block 332 is folded outward at a 90-degree angle for easy manual movement. The shape and size of the locking block 332 are adapted to the slot 321 on the outer wall of the nut 32. When the fixing plug 33 is engaged in the mounting groove 2114, the locking block 332 can be engaged in the corresponding slot 321 to restrict the rotation of the nut 32 around the axis of the mounting post 2113.

[0025] Through the cooperation of positioning component 2 and disassembly / assembly auxiliary component 3, during the disassembly / assembly process, when the groove 311 at the top of support rod 31 is fully engaged with the protrusion 2112 at the bottom of auxiliary wheel 2111, it can be ensured that support rod 31 will not shift. At least two sets of positioning components 2 are symmetrically distributed on both sides of the output shaft axis of the drive motor 111, ensuring that the inverted disc 1111 receives uniform support force during assembly and disassembly. The hydraulic cylinder 21 in each positioning component 2 drives the connecting rod 211 and auxiliary wheel 2111 to move up and down via the piston rod, thereby moving the mounting column 2113 and support rod 31. When the top of the support rod 31 contacts the bottom of the inverted disc 1111, tightening the nut 32 on the outer wall of the mounting column 2113 presses the support rod 31 firmly at a preset height position, allowing it to stably bear the weight of the inverted disc 1111. When disassembling the connecting bolts between the inverted disc 1111 and the output shaft of the drive motor 111, the support rod 31 effectively prevents the inverted disc 1111 from shaking or shifting due to the loss of bolt restraint, avoiding potential safety accidents caused by the shaking of the inverted disc 1111 and ensuring the personal safety of the operators.

[0026] By setting a fixing plug 33, the pin 331 is snapped into the mounting groove 2114 on the bottom end face of the mounting post 2113, and at least one locking block 332 with its top folded outward at 90 degrees is hinged to the outer wall of the pin 331 for easy manipulation by hand. The shape and size of the locking block 332 are adapted to the locking groove 321 on the outer wall of the nut 32. When it is necessary to release the rotation restriction of the nut 32, simply push the locking block 332 outward by hand to disengage it from the locking groove 321 on the outer wall of the nut 32, and the fixing plug 33 can be pulled out of the mounting groove 2114 by external force. During installation, the fixing plug 33 is pushed back into the mounting groove 2114, and the locking block 332 is rotated to engage with the locking groove 321, thus restricting the rotation of the nut 32. The support rod 31 is slidably fitted onto the outer wall of the mounting post 2113 through a through hole at its top that matches the mounting post 2113. Its position on the mounting post 2113 can be adjusted by loosening or tightening the nut 32 clockwise or counterclockwise. The support rod 31 can be freely rotated around the axis of the mounting post 2113. When it is necessary to turn the support rod 31, which was originally located outside the inverted plate 1111, towards the inverted plate 1111, simply rotate the support rod 31 180 degrees around the axis of the mounting post 2113 until its top groove 311 aligns with the protrusion 2112 at the bottom of the auxiliary wheel 2111, and then push the support rod 31 upwards to position it. When it is not necessary to support the inverted plate 1111, the support rod 31 is moved away from the inverted plate 1111 to prevent physical contact between the support rod 31 and the steel wire. Even if the steel wire experiences slight deviation or swaying during high-speed movement, the support rod 31, being positioned away from the steel wire, will not collide or rub against it.

[0027] Workflow First, push the locking block 332 on the fixing plug 33 outward to disengage the locking block 332 from the locking groove 321 on the outer wall of the nut 32, thereby releasing the restriction on the rotation of the nut 32; then, use external force to pull the fixing plug 33 out of the mounting groove 2114 at the bottom of the pin 331 downward, so that the pin 331 of the fixing plug 33 is completely separated from the mounting groove 2114. Loosen the nut 32 on the outer wall of the mounting post 2113 clockwise to gradually release the clamping and fixing effect of the nut 32 on the support rod 31; then pull the support rod 31 downward along the axis of the mounting post 2113 so that the groove 311 at the top of the support rod 31 is completely disengaged from the protrusion 2112 at the bottom of the auxiliary wheel 2111, releasing the locking between the two. At this time, the support rod 31 can rotate freely around the axis of the mounting post 2113. Rotate the support rod 31 180 degrees around the axis of the mounting post 2113, so that the support rod 31, which was originally located outside the inverted plate 1111, turns towards the inverted plate 1111. During the rotation, continuously observe the position of the groove 311 at the top of the support rod 31. After the groove 311 is completely aligned with the protrusion 2112 at the bottom of the auxiliary wheel 2111, push the support rod 31 upward and slide it along the axis of the mounting post 2113 until the protrusion 2112 is completely inserted into the groove 311, thereby achieving the positioning of the support rod 31. Tighten the nut 32 on the outer wall of the mounting post 2113 counterclockwise to press and fix the support rod 31 at the preset height position of the mounting post 2113. At this time, the top of the support rod 31 is in contact with the bottom of the inverted plate 1111, forming a support for the inverted plate 1111. Then, put the spare fixing plug 33 back into the mounting groove 2114 at the bottom of the mounting post 2113 and rotate the locking block 332 on the fixing plug 33 so that the locking block 332 is locked into the locking groove 321 of the nut 32, which again restricts the rotation of the nut 32 around the axis of the mounting post 2113. Use a special tool to gradually loosen the connecting bolts between the inverted disc 1111 and the output shaft of the drive motor 111. During the disassembly process, always rely on the support rod 31 to support the inverted disc 1111. Start the hydraulic cylinder 21 in the positioning component 2, and control the piston rod of the hydraulic cylinder 21 to slowly extend downward, driving the mounting column 2113, support rod 31 and the supported inverted plate 1111 to move down synchronously; continuously observe the downward trajectory of the inverted plate 1111 until it is completely lowered to the ground or the preset transfer device, at which point the inverted plate 1111 is released from the support of the support rod 31; finally, the inverted plate 1111 is removed from the inverted plate pulling machine body 1 by external transfer equipment, completing the entire disassembly process.
