Description

Technical Field

[0001] The present invention relates to the technical field of four-side extrusion molding machines, and more particularly to a CS outer coil superconducting conductor molding machine. Background Art

[0002] Superconducting conductor reshaping is a relatively important and frequently used manufacturing process in superconducting conductor manufacturing. It involves reshaping an existing product into another shape based on the application requirements. For example, a round or square tubular superconducting conductor can be reshaped into a square or round tubular superconducting conductor. Currently, this process utilizes a reshaping device consisting of a planar pressure wheel. By placing the planar pressure wheel reshaping device at a specific location or point on the superconducting conductor, the planar reshaping device forms a threshold reshaping method for the superconducting conductor, achieving a one-time reshaping of the superconducting conductor. Existing modification and manufacturing devices and methods of this type have low production efficiency and low product processing precision. In particular, if a one-time large variable expansion and contraction rate deformation molding method is used, it may not only affect and change the original properties of the superconducting conductor material, but also easily cause conductor damage during the manufacturing process, resulting in a reduced yield rate and waste of raw materials. In addition, the modified superconducting conductor is also very likely to undergo stress-induced recovery deformation, resulting in low precision, large errors, and low product qualification rate.

[0003] Therefore, in response to the current problems, how to provide a CS outer coil superconducting conductor forming machine that can ensure is an issue that those skilled in the art urgently need to solve. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example:

[0038] See attached Figure 1-11 The embodiment of the present invention discloses a CS outer coil superconducting conductor forming machine, comprising:

[0039] The molding machine body 6 has a feed port 7 and a discharge port 8 on both sides thereof, and a primary pressing device 1, a secondary pressing device 2 and a shaping device 3 are sequentially arranged inside the molding machine body 6 along the direction from the feed port 7 to the discharge port 8;

[0040] The primary pressing device 1 includes two sets of three-roller centering pressing mechanisms 11 and a first transmission mechanism 12. The two sets of three-roller centering pressing mechanisms 11 are respectively installed on both sides of the first support plate 13. Each set of three-roller centering pressing mechanisms 11 includes three first pressing roller assemblies 111.

A first through hole is opened on the first support plate 13 corresponding to the first forming hole 14; the output end of the first transmission mechanism 12 is respectively connected to the input end of the two sets of three-roller centering pressing mechanisms 11;

[0041] The secondary pressing device 2 includes four second pressing roller assemblies 21 and a second transmission mechanism 22. The four second pressing roller assemblies 21 are mounted in a cross shape on a second support plate 23, and a second forming hole is formed in the middle. The second support plate is provided with a second through hole corresponding to the second forming hole. There are four second transmission mechanisms 22, and their power output ends are correspondingly connected to the power input end of each second pressing roller assembly 21.

[0043] In order to further optimize the above technical solution, each first pressing roller assembly 111 includes a first mounting seat 1111, a first mounting shaft 1112 and a first pressing roller 1113. The first mounting seat 1111 is installed on the first support plate 13, and a mounting cavity is opened on the first mounting seat 1111; the two ends of the first mounting shaft 1112 are rotatably connected to the first mounting seat 1111, and the ends close to each other are rotatably abutted; the first pressing roller 1113 is located in the mounting cavity and is fixedly connected to the first mounting shaft 1112. One end of each first pressing roller 1113 is surrounded by a first forming hole 14.

[0044] In order to further optimize the above technical solution, the first transmission mechanism 12 includes a first driving motor 121, a transmission gear 122 and a first driven gear 123. The mounting end of the first driving motor 121 is fixed to the upper part of the first support plate 13; the transmission gear 122 includes a main gear 1221, a transmission shaft 1222 and a slave gear 1223. The main gear 1221 is fixed to the output shaft of the first driving motor 121; there are two transmission shafts 1222, and one end of each group of three-roller centering pressing mechanisms 11 is respectively connected to the first mounting shaft 1112 of each group; there are two slave gears 1223, which are respectively fixed on the transmission shaft 1222 and meshed with the main gear 1221; each first mounting shaft 1112 connected to the transmission shaft 1222 is fixed with a first driven gear 123 on both sides of the corresponding first pressing roller 1113, and the first driven gear 123 is fixed on the first mounting shaft 1112 close to the first mounting shaft 1112 connected to the transmission shaft 1222 and meshes with each other.

[0045] In order to further optimize the above technical solution, each second pressing roller assembly 21 includes a second mounting seat 213, a second mounting shaft 211 and a second pressing roller 212. The second mounting seat 213 is vertically mounted on the side of the second support plate 23 close to the feed port 7; one end of the second mounting shaft 211 is vertically rotatably connected to the second mounting seat; the second pressing roller 212 is fixed on the second mounting shaft 211.

[0046] Specifically, the second pressing roller 212 is made of high-quality alloy tool steel and is processed by forging, carburizing, etc. to optimize the internal crystal structure of the material and strengthen the surface material hardness, thereby improving the stiffness and fatigue resistance of the second pressing roller 212.

[0047] In order to further optimize the above technical solution, the second transmission mechanism 22 includes a second drive motor 221, a driving wheel 222, a power transmission shaft 223 and a driven wheel 224. The mounting end of the second drive motor 221 is fixed to the side of the second support plate 23 close to the discharge port 8; the driving wheel 222 is fixed to the output end of the second drive motor 221; the power transmission shaft 223 is rotatably connected to the side of the second support plate 23 close to the feed port 7 through the support seat 225; the driven wheel 224 is fixedly sleeved on one end of the power transmission shaft 223 and meshed with the driving wheel 222. A tooth pattern 1 2231 is provided on the circumferential side of the other end of the power transmission shaft 223, and a tooth pattern 2 2111 is provided on the other end of the second mounting shaft 211, and the tooth pattern 1 2231 and the tooth pattern 2 2111 are meshed.

[0048] Specifically, a bearing is provided at each end of the power transmission shaft 223 , and the rotation connection of the power transmission shaft 223 is achieved through the bearings.

[0049] In order to further optimize the above technical solution, the shaping device 3 also includes a shaping bracket 32 ​​and four shaping support seats 33. The shaping bracket 32 ​​is provided with four mounting grooves 34, and the four mounting grooves 34 are connected in a cross shape; each shaping support seat 33 is respectively arranged in the four mounting grooves 34, and is respectively rotatably connected to a roller shaft 35, and each roller shaft 35 is connected to a shaping roller 31 through a rolling bearing 37.

[0050] Specifically, the shaping roller 31, the core component of the shaping device, is made of high-quality alloy tool steel. It undergoes forging and carburizing processes to optimize the material's internal crystal structure and enhance surface hardness. The resulting conductor's dimensions and surface roughness meet desired requirements.

[0051] In order to further optimize the above technical solution, a roller adjustment device 4 is also included. There are four roller adjustment devices 4, which are respectively located in the installation groove 34. Each roller adjustment device 4 includes an active bevel 41 and a passive bevel 42. The inclined surface of the active bevel 41 contacts the inclined surface of the passive bevel 42. The active bevel 41 is provided with an adjustment threaded hole, and an adjustment screw 43 is threadedly connected to the adjusting threaded hole; the active bevel 41 is also provided with a long hole, and the passive bevel 42 is provided with a limiting hole. A limiting rod 44 is passed through the long hole and the limiting hole.

[0052] Specifically, the passive wedge 42 in the secondary pressing device 2 is fixed to a surface of the second mounting seat 213 away from the second pressing roller 212 .

[0053] The passive wedge 42 in the shaping device 3 is fixed to the side of the shaping support seat 33 away from the shaping roller 31 .

[0054] When it is necessary to drive the second pressing roller 212 or the shaping roller 31 toward the location of the center conductor, it is only necessary to rotate the adjusting screw 43. Since the adjusting screw 43 itself does not move axially, it can drive the active wedge 41 to move along the axial direction of the adjusting screw 43, thereby pushing the passive wedge 42 toward the location of the center conductor, thereby narrowing the gap between the second pressing rollers 212 or the shaping roller 31. If the gap between the second pressing rollers 212 or the shaping roller 31 is required, it is only necessary to rotate the adjusting screw 43 in the opposite direction. When the conductor passes through the second pressing roller 212 or the shaping roller 31, the second pressing roller 212 or the shaping roller 31 can be pushed outward, thereby increasing the gap between each second pressing roller 212 or the shaping roller 31.

[0055] In addition, a long hole is provided on the active wedge 41, and a limiting hole is provided on the passive wedge 42. The diameter of the long hole is larger than that of the limiting hole, and the axial directions of the long hole and the limiting hole are both Figure 6In addition, a limiting rod 44 is provided in the elongated hole and the limiting hole. The purpose of the limiting rod 44 is to enable the passive wedge 42 to move only along the axial direction of the limiting rod 44.

[0056] It should be noted here that even when the position of the second pressing roller 21 is adjusted, since the required adjustment size is small, the gear 1 2231 on the power transmission shaft 223 and the gear 2 2111 on the second installation shaft 211 will not be disengaged from each other, so that normal power transmission between the power transmission shaft 223 and the second installation shaft 211 can still be achieved.

[0057] In addition, the second mounting seat 213 and the shaping support seat 33 are also provided with a measuring rod, and a micrometer 45 is provided on the outside of the forming machine body 6. The measuring end of the micrometer 45 can be against the measuring rod, so that the specific position of the second pressing roller 212 or the shaping roller 31 can be monitored in real time.

[0058] In order to further optimize the above technical solution, a straightening guide device 5 is provided between the primary pressing device 1 and the secondary pressing device 2 and at the discharge port 8. The straightening guide device 5 includes a plurality of vertical straightening roller groups 51 and a plurality of horizontal straightening rollers 52. The vertical straightening roller groups 51 and the horizontal straightening rollers 52 are arranged alternately, and each vertical straightening roller group 51 includes two vertical rollers.

[0059] Specifically, the number of horizontal straightening rollers 52 and vertical straightening roller sets 51 in the straightening guide device 5 between the primary pressing device 1 and the secondary pressing device 2 is different from that in the straightening guide device 5 provided at the discharge port 8. The straightening guide device 5 between the primary pressing device 1 and the secondary pressing device 2 is provided with three horizontal straightening rollers 52 and two sets of vertical straightening roller sets 51 to ensure that the conductor enters the correct position. The number of horizontal straightening rollers 52 and vertical straightening roller sets 51 in the straightening guide device 5 provided at the discharge port 8 is greater than that in the straightening guide device 5 between the primary pressing device 1 and the secondary pressing device 2, and the specific number can be adjusted according to actual needs.

[0060] Specifically, the horizontal straightening roller 52 and the vertical straightening roller assembly 51 are both fixed to the base plate with screws. This screw connection facilitates adjustment of the positions of the horizontal straightening roller 52 and the vertical straightening roller assembly 51. Furthermore, the roller portions of the horizontal straightening roller 52 and the vertical rollers are both hard plastic rollers equipped with rolling bearings, which not only align the conductor but also protect the conductor surface from damage.

[0061] In order to further optimize the above technical solution, the molding machine body 6 includes a front fixed plate 61, a rear fixed plate 62 and a support base 63, the feed port 7 is arranged on the front fixed plate 61, the discharge port 8 is arranged on the rear fixed plate 62, and the front fixed plate 61, the rear fixed plate 62 and the second support plate 23 are all fixed on the support base 63.

[0062] In order to further optimize the above technical solution, a water injection hole 2131 is provided on the side wall of the second mounting seat 213, and a ring-shaped water injection groove 2132 is provided on the inner wall of the second mounting seat 213.

A filtering device is provided at the water outlet of the water reservoir, and the water inlet of the water reservoir is connected to the water receiving tank through a return pipe, and a return pipe is provided with a return pump. The water receiving tank is located at the bottom of the molding machine body 6.

[0063] In actual use, water in the water reservoir flows to the water injection hole 2131 through the water injection pump and water injection pipe. High-pressure water flows through the water injection hole 2131 into the water injection tank 2132. The water in the water injection hole 2131 and water injection tank 2132 flushes the copper sleeve sliding bearing. The wastewater after flushing falls downward and falls into the water receiving tank in the support base. The water in the water receiving tank flows into the water reservoir through the return pipe and return water pump, thus forming a complete water circulation process.

[0064] The method of use and working principle of the present invention are:

[0065] In actual use, the conductor is placed through the feed port 7, and the first drive motor 121 is started. At the same time, through the cooperation between the main gear 1221 and the two slave gears 1223 and the two transmission shafts 1222, and by using the first driven gear 123 installed at the position close to each other on the first mounting shaft 1112, the two sets of three-roller centering pressing mechanisms 11 can be driven to rotate simultaneously. The rotating first pressing rollers 1113 can not only drive the conductor to the direction of the secondary pressing device 2, but also press the conductor, performing a preliminary extrusion and diameter compression on the conductor, and initially pressing it into a shape similar to an ellipse. After passing through the primary pressing device 1, the conductor enters the secondary pressing device 2 again. By simultaneously starting the four second drive motors 221, through the transmission between the driving wheel 222, the power transmission shaft 223 and the driven wheel 224, the four second pressing rollers 212 can simultaneously perform a second pressing on the conductor, pressing the conductor into a shape that is approximately square. Finally, after the shaping action of the four shaping rollers 31 , the approximately square conductor is shaped and pressed into a square and is transported out from the discharge port 8 .

[0066] Specifically, the cross-sectional change of the conductor from the feed port 7 to the discharge port 8 can be referred to Figure 11 shown.
