Description

Technical Field

[0001] This utility model relates to the field of amorphous ribbon manufacturing technology, and in particular to a continuous gripping device for ultra-thin metal ribbon after forming. Background Technology

[0002] In the preparation of amorphous ribbons, molten steel is sprayed from a nozzle onto a high-speed rotating crystallizing wheel, instantly solidifying into a ribbon with a thickness of 25-30 μm, at an output speed of 20-30 m / s. Typically, only the coiled ribbon forms the final product. Given the thinness and high output speed of amorphous ribbons, a more effective gripping method is negative pressure gripping. This involves using a negative pressure winding drum close to the crystallizing wheel to attract the ribbon onto the drum, followed by winding. However, this method requires a hollow winding drum, which is typically pressed against the winding shaft by its conical surfaces on both sides. Loading and unloading the winding drum is time-consuming, and because winding can only be performed on a single drum, it limits continuous operation and mass production of the ribbon.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] like Figure 1-4 As shown in an illustrative embodiment of the continuous gripping device for ultra-thin metal strip after forming according to this utility model, the continuous gripping device for ultra-thin metal strip after forming includes at least:

[0042] Two parallel and horizontal tracks 3, with the longitudinal area between the two tracks 3 forming the working channel 31;

[0043] The gripper 4 is provided in two parts, including: a horizontally arranged reel, a winding drive device 41 for driving the reel to rotate around its own axis, a first body 42 connected to the winding drive device 41, a second body 43 rotatably connected to the first body 42, and a locking mechanism; the rotation axis of the first body 42 is vertical; when the locking mechanism is open, the first body 42 can rotate on the second body 43, and when the locking mechanism is closed, the first body 42 is fixed on the second body 43;

[0044] The two second bodies 43 slide linearly along the two tracks 3 respectively;

[0045] Both reels can be located within the working channel 31, and the two grippers 4 can move linearly simultaneously.

[0046] The locking mechanism can be opened and closed manually or based on an electrical signal.

[0047] The crystallizing roller 21 is a device that can rapidly cool the molten metal during its rotation, allowing the molten metal to solidify quickly and form a strip. When the above-mentioned continuous gripping device is in use, the track 3 is perpendicular to the axis of the crystallizing roller 21. The end of the track 3 closest to the crystallizing roller 21 is the gripping position 11. Along the length of the track 3, the gripping position 11, the winding position 12, and the rewinding position are arranged sequentially from near to far from the crystallizing roller 21. The rewinding position includes the unwinding position 13 and the loading position 14.

[0048] When producing amorphous strip, molten steel is sprayed onto the top of the rotating crystallizing roller 21. The molten steel cools rapidly on the surface of the crystallizing roller 21 and forms strip.

[0049] The two winding drive devices 41 are initially in the off state, and each of the two reels is equipped with a drum 22. The two grippers 4 are the first gripper and the second gripper, respectively.

[0050] The reel of the second gripper remains parallel to track 3; the drum 22 of the first gripper moves linearly within the working channel 31 parallel to the crystallizing roller 21, gradually approaching the crystallizing roller 21. During this movement, the winding drive device 41 of the first gripper is activated. When the linear speed of the crystallizing roller 21 surface and the reel speed of the first gripper are consistent, the reel moves to the gripping position 11 to approach the surface of the crystallizing roller 21. At this time, the strip is gripped onto the reel using negative pressure gripping technology. Subsequently, the first gripper moves to the winding position 12 to wind the strip.

[0051] When the strip winding amount on the first gripper meets the set requirements, the first gripper moves to the unwinding position 13; the second gripper moves between the unwinding position 13 and the gripping position 11, and then the reel of the second gripper rotates parallel to the crystallizing roller 21 and moves linearly within the working channel 31 to gradually approach the crystallizing roller 21. During the movement, the winding drive device 41 of the second gripper is activated. When the linear speed of the crystallizing roller 21 surface is the same as the speed of the reel of the second gripper, the reel moves to the gripping position 11 to get close to the surface of the crystallizing roller 21. At this time, the strip is sucked off and gripped onto the reel using negative pressure gripping technology. Then the second gripper moves to the winding position 12 to wind the strip. During the winding, the reel 22 on the first gripper is replaced. The reel of the first gripper remains parallel to the track 3 to wait for the next strip winding. Negative pressure gripping technology is a common method in this field, see CN103170589A, so it will not be described in detail here.

[0052] When the axis of the reel of the gripper 4 is perpendicular to the length of the track 3, the locking mechanism is closed to ensure that the first body 42 and the second body 43 remain relatively fixed during strip winding. At other times, the locking mechanism is open to allow the reel to rotate in and out of the working channel 31.

[0053] This invention enables two grippers to switch back and forth to grip the strip material without the need for strip breakage, reducing cost waste during strip production and improving production efficiency.

[0054] In some embodiments, the locking mechanism includes a wedge and a locking drive 444;

[0055] The first body 42 and the second body 43 are each provided with a groove on their adjacent sides. When the axis of the scroll is perpendicular to the length direction of the track 3, the two grooves are joined together to form a wedge groove 45 for accommodating the wedge-shaped piece. The locking drive device 444 linearly drives the wedge-shaped piece in and out of the wedge groove 45.

[0056] When the wedge is located within the wedge groove 45, the groove shape of the first body 42 of the wedge matches, preventing the first body 42 from rotating relative to the second body 43, thereby achieving the effect of fixing the first body 42 to the second body 43. When the wedge is located outside the wedge groove 45, the first body 42 can rotate relative to the second body 43.

[0057] Furthermore, the locking drive device 444 is a horizontally arranged electric telescopic device, the types of which include, but are not limited to, electric push rods, electric hydraulic cylinders, and electric pneumatic cylinders.

[0058] Furthermore, the end of the wedge away from the locking drive device 444 is narrower than the end of the wedge close to the locking drive device 444, in order to reduce the difficulty of aligning the wedge with the wedge groove 45.

[0059] In some embodiments, the locking mechanism further includes: a wedge-shaped member including a body 441 connected to the locking drive device 444, and a clamping plate 442 detachably connected to the body 441; the clamping plate 442 is located on the side of the body 441 near the first body 42.

[0060] When the wedge is in use, since the second body 43 is fixed in position and the first body 42 is movable, the part of the wedge that contacts the first body 42 is more prone to wear. Therefore, the easily worn part of the wedge is designed as a clamping plate 442 that is easy to disassemble and maintain, so as to extend the service life of the wedge by replacing the clamping plate 442.

[0061] Furthermore, the clamping plate 442 and the main body 441 are detachably connected by multiple bolts 443.

[0062] Furthermore, the clamping plate 442 is provided with countersunk holes for accommodating bolts 443 to reduce wear of the bolts 443 on the first body 42.

[0063] In some embodiments, the gripper 4 further includes: a rotary drive device for driving the first body 42 to rotate, and a sliding drive device for driving the second body 43 to slide on the track 3; the output end of the winding drive device 41 is connected to a reel, the output end of the rotary drive device is connected to the first body 42, and the sliding drive device drives the second body 43 to slide on the track 3. The driving principle of the winding drive device 41 is similar to that of a rotary motor, and the driving principle of the sliding drive device is similar to that of a track-type electric trolley or a linear drive device.

[0064] Furthermore, the second body 43 is connected to the rotary drive device and the sliding drive device, and the second body 43 is slidably connected to the track 3;

[0065] Furthermore, both the rotary drive and the sliding drive are located within the second body 43. The sliding drive operates on the same principle as the track-type electric trolley. The rotary drive and the sliding drive are not shown in the figure. A roller 22 is mounted on the roller in the figure, therefore the roller is not shown in this figure.

[0066] In some embodiments, the reel includes:

[0067] The main shaft is connected to the winding drive device 41;

[0068] Multiple expansion and contraction components are arranged around the axis of the main shaft;

[0069] The expansion and contraction drive device is used to drive all expansion and contraction components to reciprocate radially along the main shaft.

[0070] The spindle, expansion and contraction components, and expansion and contraction drive device are not shown in the diagram.

[0071] When the expansion and contraction drive device drives all the expansion and contraction components to tighten inside the drum 22, the drum 22 is mounted on the shaft. At this time, by driving all the expansion and contraction components to move towards the spindle axis through the expansion and contraction drive device, the drum 22 can be detached from the shaft. The movement principle of the expansion and contraction components is the same as the hydraulic / mechanical spring expansion and contraction structure principle in CN103170589A or the opening and closing principle of the machine tool chuck, and will not be elaborated further here.

[0072] In some embodiments, the continuous gripping device further includes:

[0073] The unloading workbench 5 is set on each side of the track 3.

[0074] There is one loading worktable 6 on each side of the track 3.

[0075] In some embodiments, the distances from the gripping position 11 along the length of the track 3 from the nearest to the farthest are gripping position 11, unloading position 13, and loading position 14. The two unloading worktables 5 are aligned with the unloading position 13, and the two loading worktables 6 are aligned with the loading position 14.

[0076] The movement route of the gripper 4 is smooth, with the shortest path and the highest movement efficiency.

[0077] In some embodiments, the loading table 6 includes:

[0078] The roll holder 61 is used to accommodate multiple linearly arranged rolls 22;

[0079] The first drive device 62 is used to push the drum 22 at one end of the drum frame 61 toward the spool that is stopped at the loading position 14;

[0080] The second driving device is used to push the drum 22 in the drum frame 61 towards the first driving device 62 along the arrangement direction of the drum 22. The driving principle of the second driving device is a common linear driving principle in the art, and the second driving device is not shown in the figure.

[0081] The loading steps for a single gripper 4 are as follows:

[0082] The second drive device pushes the roll 22 in the roll holder 61 toward the first drive device 62, so that there is always a roll 22 in front of the output end of the first drive device 62. The gripper 4 is located at the loading position 14, and the roll of the gripper 4 is aligned with the first drive device 62. The expansion and contraction drive device of the roll drives all the expansion and contraction parts of the roll to move toward the main shaft axis. Then the first drive device 62 pushes the roll 22 in front of the output end onto the roll. Then the expansion and contraction drive device drives all the expansion and contraction parts away from the main shaft axis and tightens them inside the roll 22, thus assembling the roll 22 onto the roll.

[0083] In some embodiments, the unloading workbench 5 includes:

[0084] The bracket 51 has a mounting groove on its top surface for receiving the coiled strip 23. The coiled strip 23 is fixed in position within the mounting groove.

[0085] A lifting device is used to drive the bracket 51 to rise and fall. The lifting device is a common structure in the mechanical field and is not shown in the figure.

[0086] The unloading steps for a single gripper 4 are as follows:

[0087] The gripper 4 is located at the unloading position 13, and the roll of the gripper 4 is located above the bracket 51. The lifting device drives the bracket 51 to rise, so that the bracket 51 holds the rolled strip 23 on the roll. The expansion and contraction drive device of the roll drives all the expansion and contraction parts of the roll to move towards the main shaft axis to release the drum 22 at the center of the rolled strip 23. The gripper 4 moves to the loading position 14, and the lifting device drives the bracket 51 to descend.

[0088] In some embodiments, the track 3 is located below the second body 43 and the first body 42 is located above the second body 43, so as to improve the reliability of the sliding connection between the track 3 and the gripper 4 by means of the gripper's own weight.

[0089] In some embodiments, orbital 3 includes:

[0090] Base 32.

[0091] Multiple linear guide rails 33 are detachably connected to the base 32. These linear guide rails 33 are parallel to each other. The bottom of the second body 43 is provided with grooves to accommodate the linear guide rails 33, with each linear guide rail 33 corresponding to a groove. Each linear guide rail 33 is inserted into its corresponding groove and slides within that groove.

[0092] By limiting the sliding direction of a single gripper 4 with multiple linear guide rails 33, the limiting effect of the rails 3 on the sliding direction of the gripper 4 can be improved.

[0093] Figure 1 Two linear guides 33 are provided.

[0095] This invention enables two grippers to switch back and forth to grip the strip material without the need for strip breakage, reducing cost waste during strip production and improving production efficiency.

[0096] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0097] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
