All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without any creative effort belong to the protection scope of the embodiments of the present disclosure. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Superconducting cables are increasingly widely used in the power industry because of their advantages such as high capacity and low loss. The superconducting cable comprises a plurality of superconducting strips, and two superconducting strips are often required to be welded in the process of manufacturing the superconducting cable.
In the related art, during welding, a worker cuts the ends of two superconducting tapes to be welded by using scissors so that the ends of the superconducting tapes form a welding inclined plane, overlaps the ends of the two superconducting tapes after the cutting is finished so that the ends of the two superconducting tapes are partially overlapped, coats soldering tin between the superconducting tapes in an overlapping area, and then applies pressure to the overlapping area to weld the two superconducting tapes.
However, the welding slope of the end of the superconducting tape is low in accuracy by the worker manually cutting the superconducting tape to form the welding slope, thereby affecting the welding quality of the superconducting cable.
In view of this, the embodiment of the present disclosure provides a superconducting tape blanking apparatus, which is used to replace a worker to cut a superconducting tape, so as to improve the precision of a welding slope at an end of the superconducting tape.
The superconducting tape blanking apparatus provided by the embodiments of the present disclosure is described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 4, an embodiment of the present disclosure provides a superconducting tape blanking device, which includes a cutting device 100, a machine frame 200, and a driving device 300 disposed on the machine frame 200.
The frame 200 is used to support and connect the driving device 300 and the cutting device 100. Illustratively, the frame 200 includes a top plate and a bottom plate disposed in parallel and spaced apart, the top plate and the bottom plate are connected by a side plate, the driving device 300 is disposed on a side of the top plate facing away from the bottom plate, and the cutting device 100 is disposed on a side of the bottom plate facing the top plate.
The cutting device 100 comprises a punch 190 connected to a drive 300, and a lower die plate 110 arranged on the side of the punch 190 facing away from the drive 300. The lower die plate 110 is provided with a punched hole 111, the punch 190 is provided with a cutting edge, and the driving device 300 drives the punch 190 to move toward the lower die plate 110 so that the punch 190 is inserted into the punched hole 111 during cutting. After the punch 190 is inserted into the punch 111, the cutting edge of the punch 190 is engaged with the wall of the punch 111, so that the superconducting tape 400 placed on the lower template 110 is subjected to a shearing force, and a part of the superconducting tape 400 falls off under the action of the shearing force, thereby completing the cutting of the superconducting tape 400. The connection between the punch 190 and the driving device 300 may be directly connected or may be connected through other components, as long as the driving device 300 can drive the punch 190 to move toward the lower plate 110 and at least partially insert into the punched hole 111.
At the time of cutting, the end of the superconducting tape 400 is inserted into the cutting device 100, the superconducting tape 400 is placed on the lower mold 110, the end of the superconducting tape 400 is placed over the punch holes 111, and the driving device 300 drives the punch 190 to move, thereby cutting the end of the superconducting tape 400 into the shape shown in fig. 5. The shape of the cut superconducting tape 400 can be flexibly set by changing the shapes of the punch 190 and the punch hole 111 as needed.
According to the blanking equipment for the superconducting tapes provided by the embodiment of the disclosure, the cutting device 100 comprises a punch 190 connected with the driving device 300 and a lower template 110 arranged on one side of the punch 190, which is far away from the driving device 300, wherein a punched hole 111 is arranged on the lower template 110, and a cutting edge is arranged on the punch 190; the driving means 300 is for driving the punch 190 to move toward the lower template 110 so that the punch 190 is inserted into the punch 111 to cut the superconducting tape 400 placed on the lower template 110. Compared with the manual cutting which is influenced by subjective factors such as the skill level and the proficiency level of workers, the driving device 300 drives the punch 190 to be matched with the punching hole 111 to cut the superconducting tape 400, the cutting is not influenced by the human factors, and the precision of the welded inclined plane obtained by cutting is improved. Moreover, because the shapes of the punch 190 and the punched hole 111 are fixed, the shapes of the welding inclined planes after each cutting are uniform, namely, the repeatability precision is high, and the performance of the superconducting tape 400 after welding is improved.
Optionally, the cutting device 100 further includes an upper mold plate 120 located on a side of the lower mold plate 110 facing the driving device 300, the upper mold plate 120 is provided with first guide pillars 160, and the lower mold plate 110 is provided with first guide holes 112 for cooperating with the first guide pillars 160. The driving means 300 is connected to the upper die plate 120, and the punch 190 is disposed on a side of the upper die plate 120 facing the lower die plate 110. When cutting, the driving means 300 applies a driving force to the upper template 120, and the upper template 120 moves toward the lower template 110 under the restriction of the first guide posts 160 and the first guide holes 112, so that the punches 190 mounted on the upper template 120 are inserted into the punched holes 111, thereby completing the cutting of the superconducting tape 400. Thus, the matching precision of the punch 190 and the punched hole 111 is higher, and the precision of the welding inclined plane after the superconducting tape 400 is cut is improved.
On this basis, the first guide posts 160 and the second guide holes may be plural, and the plural first guide posts 160 are spaced apart along the circumferential direction of the upper die plate 120. This further improves the accuracy of the fit between the punch 190 and the punched hole 111. Illustratively, the upper plate 120 is a rectangular plate, one first guide post 160 is disposed at each corner of the rectangular plate, and the first guide holes 112 of the lower plate 110 correspond to the first guide posts 160 one by one. Of course, the number of the first guiding studs 160 may also be two, three, etc.
Optionally, the cutting device 100 further includes a stripper plate 130 located between the upper die plate 120 and the lower die plate 110, and an elastic element 180 located between the stripper plate 130 and the upper die plate 120, the stripper plate 130 is provided with a slide hole and a through hole facing the punch 190, and the first guide column 160 is inserted into the slide hole. The first guiding pillar 160 is provided with a limiting portion, and the limiting portion abuts against one side of the stripper plate 130 departing from the upper die plate 120, so that the stripper plate 130 can only slide between the upper die plate 120 and the limiting portion. The elastic member 180 is coupled to the upper mold plate 120 and the stripper plate 130, and the elastic member 180 serves to abut the stripper plate 130 against the lower mold plate 110. The first guide posts 160 may be stepped posts, including thin posts inserted into the sliding holes and thick posts coaxially connected to the thin posts, and the stripper plate 130 is limited to slide onto the thick posts by the step between the thin posts and the thick posts. Of course, the position-limiting part may be a position-limiting protrusion provided on the surface of the first guide post 160. The elastic member 180 may be a spring disposed parallel to the first guide post 160, a disc spring, etc., as long as it provides an elastic force to move the stripper plate 130 in a direction away from the upper die plate 120.
When cutting, the driving device 300 drives the upper template 120 to make the upper template 120 drive the stripper plate 130 to move towards the lower template 110, so that the stripper plate 130 contacts the superconducting tape 400, and the stripper plate 130 and the lower template 110 clamp the superconducting tape 400 to play a role in positioning the superconducting tape 400. After the stripper plate 130 contacts the superconducting tape 400, the stripper plate is stationary under the abutting action of the superconducting tape 400 and the lower template 110, and the upper template 120 extrudes the elastic element 180 to move towards the lower template 110 continuously, so that the punch 190 penetrates through the through hole to be matched with the punched hole 111, and the cutting of the superconducting tape 400 is realized. After the cutting is completed, the upper template 120 drives the punch 190 to move in the direction away from the lower template 110, so that the punch 190 is released from the punched hole 111, and the stripper plate 130 continuously abuts against the superconducting tape 400 under the action of the elastic element 180, thereby preventing the punch 190 from lifting the superconducting tape 400 and causing the tape phenomenon. After the upper template 120 drives the first guiding pillars 160 to move for a certain distance along the direction departing from the lower template 110, the limiting part drives the stripper plate 130 to move, so that the stripper plate 130 is separated from the superconducting tape 400. In this way, the stripper plate 130 may function to position the superconducting tape 400 and prevent the punch 190 from lifting up the superconducting tape 400 after the cutting is completed.
Optionally, a second guide post 170 with a center line parallel to the first guide post 160 is disposed on one side of the upper template 120 facing the lower template 110, and a second guide hole matched with the second guide post 170 is disposed on the stripper plate 130. The second guide post 170 is provided to allow the stripper plate 130 to slide along the second guide post 170, preventing the punch 190 from interfering with the through-hole.
On this basis, the number of the second guide posts 170 may be plural, and a plurality of the second guide posts 170 are spaced apart along the circumferential direction of the upper die plate 120. For example, the number of the second guiding studs 170 may be four, and four second guiding studs 170 are respectively located at four vertices of the rectangle. Of course, the number of the second guiding studs 170 may also be two, three, etc. The plurality of second guide posts 170 are provided to better guide the stripper plate 130.
Optionally, the cutting device 100 further includes an upper die base 140, the upper die base 140 is disposed on a side of the upper die plate 120 facing away from the punch 190, and the driving device 300 is connected to the upper die base 140. The connection of the upper mold base 140 and the driving device 300 prevents the driving device 300 from wearing the upper mold plate 120 after the superconducting tape 400 is used for a certain period of time. Also, the punch 190 may be mounted on the upper die plate 120 from the side of the upper die plate 120 facing the upper die base 140, and then the punch 190 is fixed by the upper die base 140, so that replacement of the punch 190 is facilitated.
There are various connection forms of the driving device 300 and the upper die base 140, and in one possible embodiment, the driving device 300 includes an air cylinder, a cylinder body of the air cylinder is connected with the frame 200, and a piston rod of the air cylinder is connected with the upper die base 140. The cylinder can perform a linear reciprocating motion, thereby enabling the upper mold plate 120 to move toward the lower mold plate 110 and away from the lower mold plate 110. Specifically, the piston rod is connected to the upper die base 140 by a floating joint, which can be used to absorb installation errors of the cylinder and the cutting device 100.
In another possible embodiment, the driving device 300 includes a motor and a cam, a surface of the cam always abuts against a surface of the upper die holder 140, and an output shaft of the motor drives the cam to rotate, so that the cam drives the cutting device 100 to act.

Illustratively, as shown in fig. 3, the guide surface 113 is a flat surface. Of course, the guide surface 113 may be a curved surface. After the superconducting tape 400 is cut, the superconducting tape 400 continues to move forward, and after the superconducting tape contacts the guide surface 113, the guide surface 113 guides the superconducting tape 400 in a direction away from the lower template 110, so that the superconducting tape 400 is prevented from being stuck in the punched holes 111.
