Description

Technical Field

[0001] The present application relates to the technical field of metal material processing, and in particular to a double-position clutch device for unwinding a copper strip. Background Art

[0002] In the copper material processing workshop, the copper strip material needs to be unrolled with the help of a reel and then fed into the conveyor belt. The rotary feeding of the reel and the clamping feeding of the pinch roller correspond to an active process and a passive process respectively. The rotary feeding of the reel relies on the self-rotation of the reel to feed the material head into the pinch roller, and the pinch roller feeding relies on its own rotation to unroll the copper strip material roll. This process needs to exclude the self-rotation of the reel. Therefore, the process of the reel conveying the material head to the pinch roller is the process of switching between the active and passive functions. During the switching process, an instantaneous radial displacement will occur at the power transmission position of the active transmission. Since the mass of the copper strip material roll is large, the impact caused by the displacement will affect the effect of the active and passive function switching and the feeding smoothness. At present, the existing technology still has no corresponding solution for this. Summary of the invention

[0003] The present application provides a double-position clutch device for unwinding a copper strip, which solves the problem of stable switching of the active and passive functions of unwinding the copper strip.

[0004] The technical solution of this application is as follows: A copper strip unwinding double-position clutch device comprises a reel and a copper coil wound on the reel, wherein the reel has an active structure for driving the reel to rotate, the active structure uses a reducer as a power source, and the active structure comprises: The main shaft, which serves as a transmission structure, is connected to the reel at one end; A bearing box, passing through the main shaft, for bearing the radial force of the reel; A first coupling, which is clearance-matched with the main shaft and can move axially along the main shaft; A second coupling, connected to the reducer, and having coupling teeth that can cooperate with the first coupling; a first cylinder body surrounding the first coupling and the second coupling; A connecting bearing, an inner ring of which is fixedly connected to the first coupling, and an outer ring of which is fixedly connected to the first cylinder body; A second cylinder body surrounds the first cylinder body, and the second cylinder body has a sealing cover and a piston, and the piston is constructed to move together with the first cylinder body; the piston can slide in the second cylinder body to pull the first cylinder body to drive the first coupling to move, so that the first coupling has a first state of cooperation with the second coupling and a second state of disengagement from the second coupling.

[0005] Furthermore, the reel has a passive structure for driving the reel to rotate, and the passive structure is a conveying roller, and the conveying roller clamps the material head of the copper strip.

[0006] Furthermore, the first coupling has coupling teeth.

[0007] Furthermore, the coupling tooth has a chamfer.

[0008] Furthermore, a bearing cover is provided on one side of the connecting bearing, and the bearing cover is threadedly connected to the first cylinder body.

[0009] Furthermore, the piston divides the interior of the second cylinder into a first space and a second space; The outer circumference and inner surface of the sealing cover are respectively provided with a communicating oil filling groove and an oil filling hole, and the oil filling hole is communicated with the first space; The second cylinder body is provided with oil delivery holes which are respectively connected to the oil filling groove and the second space.

[0010] Furthermore, an annular groove is provided on the outer periphery of the first cylinder body, and the piston is provided with a clamping ring clampedly connected to the annular groove.

[0011] Due to the adoption of the above technical solution, the beneficial effects of this application are as follows: 1. The present application realizes the matching between the couplings by driving the first coupling to move axially through the movement of the piston in the second cylinder. Under the working condition of the coupling rotating matching, the present application offsets the torsional force when the coupling contacts by rotating the inner ring of the connecting bearing, and decomposes the matching process into an axial movement process and an annular engagement process. At the moment of engagement, the annular resistance between the first coupling and the second coupling is extremely small, thus avoiding hard engagement. In other words, in the present application, when the first coupling and the second coupling are not fully engaged, the subsequent radial movement of the first coupling will no longer affect the subsequent engagement process. Therefore, the present application can significantly reduce the impact on each component at the moment of connection, and ensure the stable realization of the active process.

[0012] 2. As a preferred embodiment of the present application, the coupling teeth of the present application have chamfers, which can further reduce the rigid contact of the coupling teeth during mating, further reduce the impact, and ensure the stable connection of the coupling.

[0013] 3. As a preferred embodiment of the present application, an oil filling hole is set at the sealing cover of the present application to realize the movement of the piston to the second state, which helps to shorten the length of the second cylinder body and the first cylinder body, thereby reducing the output shaft length of the reducer and improving the integrity and stability of the device.

[0017] Based on the background technology, in the copper material processing workshop, the copper coil needs to be flattened for cutting and processing. The unfolding of the copper coil requires the help of large machinery, namely the conveyor roller. The conveyor roller is set on one side of the copper coil. After the material head of the copper coil is clamped by the conveyor roller, the conveyor roller pulls the copper coil to rotate by rolling the material head, and the copper coil is unwound. The copper coil needs to be installed on the reel. The reel has two rotation modes, active rotation and passive rotation. Active rotation means that the reel rotates by itself, and passive rotation means that the copper coil is pulled and drives the turntable to rotate. It should be noted that the reel can be realized by existing technology. The bearing box is composed of a box body and a bearing. The interior is self-lubricated with gear oil. It mainly bears the radial force of the reel and also serves as a structure for power transition to the reel. See the attached Figure 1 , in the attached Figure 1 In the figure, the reel and the bearing box are not shown as the prior art, and the reel and the bearing box are connected in series through the main shaft 2.

[0018] Based on the above, the present application provides a copper strip unwinding double-position clutch device, including a reel and a copper coil wound on the reel, the reel having an active structure for driving the reel to rotate, the active structure using a reducer 1 as a power source, and the active structure including: The main shaft 2, as a transmission structure, is connected to the reel at one end. The main shaft 2 is a transmission mechanism, and the rotation of the main shaft 2 drives the reel to rotate.

[0019] The bearing box is passed through the main shaft 2 and is used to bear the radial force of the reel. When the copper coil is placed on the reel, the bearing box is used to bear the radial force generated by the copper coil.

[0020] The first coupling 3 is loosely matched with the main shaft 2 and can move axially along the main shaft 2. Figure 5 The keyway of the first coupling 3 is matched with the main shaft 2 through a clearance fit key, and the first coupling 3 can rotate with the main shaft 2 and can also be displaced left and right along its axial direction.

[0021] The second coupling 4 is connected to the reducer 1 and has a coupling tooth 5 that can cooperate with the first coupling 3. As an example but not a limitation, the reducer 1 can be a cycloidal pinwheel reducer 1, which can provide a stable speed and torque of the reel by converting the speed ratio.

[0022] The first cylinder body 6 surrounds the first coupling 3 and the second coupling 4. Figure 2 and attached Figure 3 The first cylinder 6 does not contact the first coupling 3 and the second coupling 4 to allow the first coupling 3 and the second coupling 4 to rotate inside it.

[0023] The inner ring of the connecting bearing 8 is fixedly connected to the first coupling 3, and the outer ring of the connecting bearing 8 is fixedly connected to the first cylinder body 6. The connecting bearing 8 is a structure for linking the first cylinder body 6 and the first coupling 3.

[0024] The second cylinder 7 surrounds the first cylinder 6. The second cylinder 7 has a sealing cover 9 and a piston 10. The piston 10 is configured to move together with the first cylinder 6. The piston 10 can slide in the second cylinder 7 to pull the first cylinder 6 to drive the first coupling 3 to move, so that the first coupling 3 has a first state of matching with the second coupling 4 and a second state of being separated from the second coupling 4. Figure 2 and attached Figure 3 The sealing cover 9 is slidably connected to the outer periphery of the first cylinder body 6 and has a plurality of rings for auxiliary sliding. Figure 2 In the figure, the piston 10 is in the second state, and the state switching is realized after oil is injected into the second cylinder 7, and the reel is switched to the active state. It should be noted that the second cylinder 7 is provided with a base for supporting the active structure in the figure, and the second cylinder 7 remains fixed when the piston 10 moves.

[0025] As a preferred embodiment of the present application, the reel has a passive structure for driving its rotation, and the passive structure is a conveying roller, and the conveying roller clamps the material head of the copper strip.

[0026] As a preferred embodiment of the present application, the first coupling 3 has a coupling tooth 5. The second coupling 4 has the same structure as the first coupling 3 and is arranged opposite to the first coupling 3. The second coupling 4 is fixed to the output shaft of the reducer 1 by bolts.

[0027] As a specific example of the above embodiment, the coupling tooth 5 has a chamfer 5-1. The design of the chamfer 5-1 can further reduce the rigid contact of the coupling tooth 5 when it is matched, further reduce the impact, and ensure the stable connection of the coupling. At the same time, the chamfer 5-1 can increase the contact area of ​​the coupling, reduce the buffer, and make the active structure run smoothly.

[0028] As a preferred embodiment of the present application, a bearing cap 11 is provided on one side of the connecting bearing 8, and the bearing cap 11 is threadedly connected to the first cylinder body 6. After the inner ring of the bearing is fixed, the outer ring should also be fixed, so as to increase the service life of the bearing.

[0029] As a preferred embodiment of the present application, the piston 10 divides the interior of the second cylinder body 7 into a first space 7-1 and a second space 7-2; the outer periphery and inner surface of the sealing cover 9 are respectively provided with a communicating oil filling groove 9-1 and an oil filling hole 9-2, and the oil filling hole 9-2 is communicated with the first space 7-1; the second cylinder body 7 is provided with an oil delivery hole 13 respectively connected to the oil filling groove 9-1 and the second space 7-2. Figure 2 and attached Figure 4 , the piston 10 is in the second state, and the first space 7-1 is compressed. The oil delivery hole 13 is externally connected to the oil delivery pipe, and oil is injected into the first space 7-1 or the second space 7-2 to switch the state of the piston 10. It should be noted that the oil delivery hole 13 is both the hydraulic oil inlet and the hydraulic oil return path, the oil injection groove 9-1 is circumferential, and the oil injection holes 9-2 are distributed in equal arcs on the sealing cover 9.

[0030] As a preferred embodiment of the present application, an annular groove 6-1 is provided on the outer periphery of the first cylinder body 6, and a snap ring 10-1 is provided on the piston 10 to be snap-connected with the annular groove 6-1. This structure enables the piston 10 to drive the first cylinder body 6 to move axially, thereby enabling the first coupling 3 and the second coupling 4 to engage or disengage.
