Description

Technical Field

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

[0002] The modification of superconducting conductors is an important and frequently used manufacturing process in the manufacture of superconducting conductors. It modifies a formed product into another shape according to application requirements. For example, a round or square tube-shaped superconducting conductor is modified into a square or round tube-shaped superconducting conductor. At present, this process uses a modification manufacturing device composed of a planar pressure wheel. By setting a planar pressure wheel modification manufacturing device at a certain part or point of the superconducting conductor, the planar modification manufacturing device forms a threshold modification manufacturing method for the superconducting conductor, thereby realizing a one-time modification manufacturing method of the superconducting conductor. The existing modification and processing manufacturing devices and the manufacturing methods thereof have low production efficiency and low product processing precision. In particular, if a large variable expansion and contraction rate deformation is used in one step, it may not only affect and change the original performance of the material of the superconducting conductor, but also easily cause conductor damage during the manufacturing process, resulting in a reduced yield and a waste of raw materials. Moreover, the modified superconducting conductor is also very likely to undergo stress recovery deformation, so that the modified product has low precision, large errors and a low product qualification rate.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work 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] A molding machine body 6, with a feed port 7 and a discharge port 8 respectively provided on both sides of the molding machine body 6, and a primary pressing device 1, a secondary pressing device 2 and a shaping device 3 sequentially arranged in 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 groups of three-roller centering pressing mechanisms 11 and a first transmission mechanism 12.

Each group of three-roller centering pressing mechanisms 11 includes three first pressing roller assemblies 111. The three first pressing roller assemblies 111 are rotatably abutted at one end close to each other and surround a first forming hole 14. The first support plate 13 is provided with a first through hole corresponding to the first forming hole 14. The output ends of the first transmission mechanism 12 are respectively connected to the input ends of the two groups 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.

[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; both 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, and 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, and 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, and the main gear 1221 is fixed on 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 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 meshed 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 crystal structure inside the material and strengthen the surface material hardness, thereby improving the rigidity and fatigue resistance of the second pressing roller 212.

[0047] In order to further optimize the above technical scheme, 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 on the side of the second support plate 23 close to the discharge port 8; the driving wheel 222 is fixed on 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 a 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 is meshed with the tooth pattern 2111.

[0048] Specifically, a bearing is respectively provided at both ends 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 with 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, as the core part of the shaping device, is made of high-quality alloy tool steel, and is processed by forging, carburizing, etc. to optimize the crystal structure inside the material and strengthen the surface material hardness. The conductor size and surface roughness after shaping can well meet the needs.

[0051] In order to further optimize the above technical solution, it also includes a roller adjustment device 4. There are four roller adjustment devices 4, which are respectively located in the installation groove 34. Each roller adjustment device 4 includes an active inclined wedge 41 and a passive inclined wedge 42. The inclined surface of the active inclined wedge 41 contacts the inclined surface of the passive inclined wedge 42. The active inclined wedge 41 is provided with an adjustment threaded hole, and an adjustment screw 43 is threadedly connected in the adjustment threaded hole; the active inclined wedge 41 is also provided with a long hole, and the passive inclined wedge 42 is provided with a limiting hole. A limiting rod 44 is inserted in 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 a surface 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 to move toward the position where the center conductor is located, it is only necessary to rotate the adjusting screw 43. Since the adjusting screw 43 itself does not move axially, it is possible to drive the active wedge 41 to move along the axial direction of the adjusting screw 43, thereby pushing the passive wedge 42 to move toward the position where the center conductor is located, thereby reducing the gap between the second pressing rollers 212 or the shaping rollers 31. If the gap between the second pressing rollers 212 or the shaping rollers 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 rollers 212 or the shaping rollers 31, the second pressing rollers 212 or the shaping rollers 31 can be pushed to move outward, thereby increasing the gap between each second pressing roller 212 or the shaping rollers 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 long hole and the limiting hole, and 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 adjusting the position of the second pressing roller 21, due to the small size of the adjustment required, the gear 1 2231 on the power transmission shaft 223 and the gear 2 2111 on the second installation shaft 211 will not be relatively disengaged, thereby achieving normal power transmission between the power transmission shaft 223 and the second installation shaft 211.

[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 molding 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 alternately arranged, and each vertical straightening roller group 51 includes two vertical rollers.

[0059] Specifically, the number of horizontal straightening rollers 52 and vertical straightening roller groups 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. Three horizontal straightening rollers 52 and two groups of vertical straightening roller groups 51 are provided in the straightening guide device 5 between the primary pressing device 1 and the secondary pressing device 2 to ensure that the conductor enters the correct position. The number of horizontal straightening rollers 52 and vertical straightening roller groups 51 in the straightening guide device 5 provided at the discharge port 8 is greater than that of the horizontal straightening rollers 52 and vertical straightening roller groups 51 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, in addition, the horizontal straightening roller 52 and the vertical straightening roller set 51 are fixed to the bottom plate by screws, and the screw connection facilitates the adjustment of the positions of the horizontal straightening roller 52 and the vertical straightening roller set 51. In addition, the roller parts of the horizontal straightening roller 52 and the vertical roller are hard plastic rollers with rolling bearings installed inside, which can not only play the role of straightening 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.

The water receiving tank is located at the bottom of the molding machine body 6.

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

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

[0065] In actual use, the conductor is put in from 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 the first driven gear 123 is installed at the position close to each other by the first installation shaft 1112, so that the two sets of three-roller centering pressing mechanisms 11 can be driven to rotate at the same time. The rotating first pressing roller 1113 can not only drive the conductor to be transported in the direction of the secondary pressing device 2, but also press the conductor, perform preliminary extrusion and compression on the conductor, and preliminarily press it into a shape similar to an ellipse. The conductor after the primary pressing device 1 enters the secondary pressing device 2 again, and by starting the four second drive motors 221 at the same time, 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, and press the conductor into a shape similar to a square. Finally, after being shaped by 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 .
