Description

Technical Field

[0001] This invention relates to the field of metal rolling technology, and in particular to a copper strip cold rolling forming apparatus. Background Technology

[0002] Cold rolling, often simply referred to as cold rolling, is a process of rolling and deforming metallic materials (mainly steel and non-ferrous metals) below the recrystallization temperature (usually room temperature). Cold rolling is a key deep-processing technology that improves the dimensional accuracy, surface quality, and mechanical properties of metallic materials through room-temperature plastic deformation. It is a complex system engineering project encompassing multiple stages such as rolling, annealing, and finishing, ultimately providing high-quality, high-value-added raw materials for downstream manufacturing industries.

[0003] Under normal temperature conditions, impurities and oxides are easily attached to the surface of copper strip. Existing copper strip cold rolling forming equipment is not convenient for cleaning the impurities and oxides that are tightly attached to the surface of copper strip. This makes it easy to damage the surface of copper strip and rolling rolls during cold rolling, thereby affecting the production quality of copper strip and causing economic losses. In addition, the copper strip is prone to rolling texture after rolling, which affects the rolling effect of copper strip. Summary of the Invention

[0004] To overcome the shortcomings of the above-mentioned background technology, the present invention provides a copper strip cold rolling forming apparatus, which facilitates the cleaning of impurities and oxides tightly attached to the surface of the copper strip billet, keeping the surface of the copper strip billet clean and preventing impurities on the surface of the copper strip billet from damaging the rolling rolls, thereby improving the service life of the apparatus, improving the rolling quality of the copper strip billet, and effectively reducing the rolling texture on the surface of the copper strip billet, making the surface of the rolled copper strip billet smoother and flatter, and improving the rolling effect of the copper strip billet.

[0005] The technical implementation of the present invention is as follows: a copper strip cold rolling forming device, comprising a frame, support rollers, copper strip blank, servo motor, rolling mechanism and grinding mechanism. Two sets of support rollers are installed on the frame, the two sets of support rollers are symmetrically arranged, each set has two support rollers, each support roller is rotatably connected to the frame, and a copper strip blank is placed between each set of support rollers. A servo motor is installed on one side of the frame, and a rolling mechanism is provided on the frame. The rolling mechanism is used to roll the copper strip blank to the required thickness. A grinding mechanism is provided on the frame. The grinding mechanism is used to reciprocate grinding the surface of the copper strip blank, so as to remove impurities and oxides tightly attached to the surface of the copper strip blank, and keep the surface of the copper strip blank clean.

[0006] Optionally, the support roller is used to position the copper strip blank to prevent deformation during rolling and forming, which would affect the production quality.

[0007] Optionally, the rolling mechanism includes a rotating shaft, rolling rolls, transmission gears, oil supply hoses, and a collection tank. Two rotating shafts are rotatably connected to the frame, and the two rotating shafts are symmetrically arranged. Each rotating shaft is equipped with a rolling roll, and both rolling rolls are in contact with the copper strip billet. Each rotating shaft is equipped with a transmission gear, and the two transmission gears mesh with each other. Two oil supply hoses are fixedly connected to the frame and are located on the upper and lower sides of the copper strip billet. A collection tank is installed on the frame and is located below the oil supply hoses.

[0008] Optionally, the oil supply hose is used to supply rolling oil, and the collection tank is used to collect used rolling oil. The rolling oil is used to reduce the friction and heat generated by the rolling rolls rolling the copper strip blank.

[0009] Optionally, the grinding mechanism includes a cam, a movable plate, a grinder, a meshing gear, a fixed rack, and a guide rod. A cam is mounted on one of the rotating shafts, and the cam has a wave groove. Two movable plates are slidably connected to the frame, and the two movable plates are symmetrically arranged. Several grinders are rotatably connected to each movable plate. The grinding surface of each grinder is in contact with the copper strip blank. A meshing gear is mounted on each grinder. Two fixed racks are mounted on the frame, and the two fixed racks are symmetrically arranged. Each meshing gear meshes with a fixed rack. A guide rod is connected to both movable plates, and one end of the guide rod is located in the wave groove of the cam.

[0010] Optionally, the system also includes a cleaning mechanism mounted on a frame. The cleaning mechanism includes a scraper, a rack, support rods, a swing rod, a rotating gear, brush plates, a round rod, and an oil scraper. A scraper is fixedly connected to the frame, and the scraper has a scraping groove. The copper strip passes through the scraping groove of the scraper, and the copper strip contacts the scraper. A rack is fixedly connected to each movable plate. Two support rods are fixedly connected to the frame, arranged symmetrically. A swing rod is rotatably connected to each support rod, and each swing rod has a slot. A rotating gear is installed on each swing rod, meshing with the rack. Two brush plates are slidably connected to the scraper, arranged symmetrically. A round rod is fixedly connected to each brush plate, with one end of the round rod located in the slot of the swing rod. An oil scraper is slidably connected to each brush plate, with the two oil scrapers located on opposite sides of the copper strip and connected to two oil supply hoses.

[0011] Optionally, it also includes a de-scraping mechanism, which is mounted on the frame. The de-scraping mechanism includes a support plate, a reciprocating lead screw, a transmission assembly, a movable frame, a nut, and pressure rollers. The support plate is fixedly connected to the frame and is located below the copper strip billet. The reciprocating lead screw is rotatably connected to the frame, and a transmission assembly is connected between the rotating shaft and the reciprocating lead screw. The movable frame is slidably connected to the frame, and a nut is fixedly connected to the movable frame. The reciprocating lead screw is connected to the nut via a thread. Two pressure rollers are rotatably connected to the movable frame. The two pressure rollers are symmetrically arranged and both pressure rollers are in contact with the copper strip billet. The pressure rollers are used to reduce rolling marks generated on the surface of the copper strip billet after rolling.

[0012] Optionally, the transmission assembly includes a drive wheel, a transmission wheel and a transmission belt. The drive wheel is mounted on a rotating shaft, the transmission wheel is mounted on a reciprocating lead screw, and the drive wheel and the transmission wheel are connected by a transmission belt. The transmission assembly is used to drive the reciprocating lead screw to rotate.

[0013] Beneficial effects: Two rolling rollers cold roll the copper strip blank to achieve the required thickness. The grinding surface of the grinder reciprocates to grind the surface of the copper strip blank, which facilitates the removal of impurities and oxides that are tightly attached to the surface of the copper strip blank, keeping the surface of the copper strip blank clean.

[0014] The scraper removes residual impurities from the surface of the copper strip billet, effectively preventing these impurities from damaging the rolling rolls and thus extending the service life of the equipment. The brush plate moves horizontally back and forth, ensuring more thorough cleaning of residual impurities from the copper strip billet surface. The oil scraper evenly coats the copper strip billet surface with rolling oil, ensuring full coverage and reducing dead zones in the oil coverage. This effectively improves the rolling quality of the copper strip billet, makes fuller use of the rolling oil, and reduces waste.

[0015] Two pressure rollers work in conjunction with a support plate to roll the surface of the copper strip billet, effectively reducing the rolling texture on the surface of the copper strip billet, making the surface of the rolled copper strip billet smoother and flatter, and improving the rolling effect of the copper strip billet.

Detailed Implementation

[0028] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] Example 1 A copper strip cold rolling and forming apparatus, such as Figure 1-11As shown, the assembly includes a frame 1, support rollers 2, copper strip 3, servo motor 4, a rolling mechanism, and a polishing mechanism. Two sets of support rollers 2 are installed on the frame 1, and the two sets of support rollers 2 are symmetrically arranged. Each set has two support rollers 2, and each support roller 2 is rotatably connected to the frame 1. A copper strip 3 is placed between each set of support rollers 2. A servo motor 4 is installed on one side of the frame 1 by bolts. A rolling mechanism is set on the frame 1 to roll the copper strip 3 to the required thickness. A polishing mechanism is set on the frame 1 to reciprocate polish the surface of the copper strip 3, which facilitates the polishing and cleaning of impurities and oxides that are tightly attached to the surface of the copper strip 3, so that the surface of the copper strip 3 remains clean.

[0030] The support roller 2 is used to position the copper strip blank 3 to prevent the copper strip blank 3 from deforming during rolling and forming, thereby affecting the production quality.

[0031] The rolling mechanism includes a rotating shaft 51, a rolling roller 52, a transmission gear 53, an oil supply hose 54, and a liquid collection tank 55. Two rotating shafts 51 are rotatably connected to the frame 1 via bearings. The two rotating shafts 51 are symmetrically arranged. A rolling roller 52 is installed on each rotating shaft 51. Both rolling rollers 52 are in contact with the copper strip billet 3. A transmission gear 53 is installed on each rotating shaft 51 via a flat key. The two transmission gears 53 mesh with each other. Two oil supply hoses 54 are fixedly connected to the frame 1. The two oil supply hoses 54 are located on the upper and lower sides of the copper strip billet 3. A liquid collection tank 55 is installed on the frame 1 via bolts. The liquid collection tank 55 is located below the oil supply hoses 54.

[0032] The oil supply hose 54 is used to supply rolling oil, and the collection tank 55 is used to collect used rolling oil. The rolling oil is used to reduce the friction and heat generated by the rolling rolls 52 rolling the copper strip 3.

[0033] The grinding mechanism includes a cam 61, a movable plate 62, a grinder 63, a meshing gear 64, a fixed rack 65, and a guide rod 66. A cam 61 is mounted on one of the rotating shafts 51. The cam 61 has a wave groove. Two movable plates 62 are slidably connected to the frame 1. The two movable plates 62 are symmetrically arranged. Several grinders 63 are rotatably connected to each movable plate 62 through bearings. The grinding surface of each grinder 63 is in contact with the copper strip blank 3. A meshing gear 64 is mounted on each grinder 63 through a flat key. Two fixed racks 65 are bolted to the frame 1. The two fixed racks 65 are symmetrically arranged. Each meshing gear 64 meshes with a fixed rack 65. A guide rod 66 is connected to both movable plates 62. One end of the guide rod 66 is located in the wave groove of the cam 61.

[0034] First, the operator inserts the copper strip billet 3 between four support rollers 2 and two rolling rollers 52. The operator starts the servo motor 4 and introduces rolling oil through the oil supply hose 54. The rolling oil is sprayed onto the surface of the copper strip billet 3. The output shaft of the servo motor 4 drives one of the rotating shafts 51 to rotate. The rolling roller 52 on the rotating shaft 51 rotates together with the transmission gear 53. Through the cooperation of the two transmission gears 53, the other rotating shaft 51, transmission gear 53, and rolling roller 52 rotate in opposite directions. The two rolling rollers 52 cold roll the copper strip billet 3 to achieve the required thickness. The rotating shaft 51 drives the cam 61 to rotate, and the cam 61 drives the movable plate 62 and the guide rod 66. The grinding machine 63 and the meshing gear 64 move back and forth. Through the meshing gear 64 and the fixed rack 65, the grinding machine 63 and the meshing gear 64 rotate together. The grinding surface of the grinding machine 63 grinds the surface of the copper strip 3 back and forth, which facilitates the grinding and cleaning of the impurities and oxides that are tightly attached to the surface of the copper strip 3, so that the surface of the copper strip 3 remains clean. Finally, the copper strip 3 is rolled. The operator stops the oil supply hose 54 from introducing rolling oil and shuts down the servo motor 4. The rotating shaft 51, the transmission gear 53, the rolling roller 52 and the cam 61 stop rotating together. The moving plate 62, the grinding machine 63 and the meshing gear 64 stop moving accordingly.

[0035] Example 2 Based on Example 1, such as Figure 6-11 As shown, it also includes a cleaning mechanism, which is mounted on the frame 1. The cleaning mechanism includes a scraper 71, a rack frame 72, a support rod 73, a swing rod 74, a rotating gear 75, a brush plate 76, a round rod 77, and an oil scraper 78. The scraper 71 is bolted to the frame 1. The scraper 71 has a scraping groove. The copper strip 3 passes through the scraping groove of the scraper 71 and contacts the scraper 71. Each movable plate 62 is bolted to a rack frame 72. Two support rods 73 are fixedly connected to the frame 1. The two support rods 73 are symmetrically arranged, and each support rod 73 has... A swing arm 74 is rotatably connected via a bearing. Each swing arm 74 has a slot and a rotating gear 75 is mounted on it. The rotating gear 75 meshes with a rack frame 72. Two brush plates 76 are slidably connected to the scraper 71. The two brush plates 76 are symmetrically arranged, and a round rod 77 is fixedly connected to each brush plate 76. One end of the round rod 77 is located in the slot of the swing arm 74. An oil scraper 78 is slidably connected to each brush plate 76. The two oil scrapers 78 are located on both sides of the copper strip blank 3 and are connected to two oil supply hoses 54 respectively.

[0036] The scraper 71 scrapes off the impurities remaining on the surface of the copper strip billet 3, effectively preventing the impurities on the surface of the copper strip billet 3 from damaging the rolling roll 52, thereby improving the service life of the device. The reciprocating movement of the movable plate 62 drives the rack frame 72 to reciprocate, and the rack frame 72 drives the swing rod 74 and the rotating gear 75 to swing back and forth. The swing rod 74 drives the round rod 77 and the brush plate 76 to move horizontally back and forth, so that the brush plate 76 can more thoroughly clean the impurities remaining on the surface of the copper strip billet 3. The rolling oil in the oil supply hose 54 flows into the scraper. Inside the oiler 78, the brush plate 76 drives the scraper 78 to move back and forth. The scraper 78 evenly coats the surface of the copper strip billet 3 with rolling oil, so that the surface of the copper strip billet 3 is fully covered with rolling oil, reducing the dead corners of rolling oil coverage, effectively improving the rolling quality of the copper strip billet 3, making the rolling oil more fully utilized, and reducing the waste of rolling oil. The scraper 71 drives the rack frame 72 to stop moving, the swing rod 74 and the rotating gear 75 stop swinging, and the round rod 77, the brush plate 76 and the scraper 78 stop moving accordingly.

[0037] Example 3 Based on Example 2, such as Figure 9 As shown, it also includes a de-scraping mechanism, which is mounted on the frame 1. The de-scraping mechanism includes a support plate 81, a reciprocating screw 82, a transmission assembly 83, a movable frame 84, a nut 85, and pressure rollers 86. The support plate 81 is bolted to the frame 1 and is located below the copper strip billet 3. The reciprocating screw 82 is rotatably connected to the frame 1 via bearings. The transmission assembly 83 is connected between the rotating shaft 51 and the reciprocating screw 82. The movable frame 84 is slidably connected to the frame 1, and a nut 85 is fixedly connected to the movable frame 84. The reciprocating screw 82 is connected to the nut 85 via threads. Two pressure rollers 86 are rotatably connected to the movable frame 84. The two pressure rollers 86 are symmetrically arranged and both pressure rollers 86 are in contact with the copper strip billet 3. The pressure rollers 86 are used to reduce the rolling marks generated on the surface of the copper strip billet 3 after rolling.

[0038] The transmission assembly 83 includes a drive wheel, a transmission wheel and a transmission belt. The drive wheel is mounted on the rotating shaft 51, and the transmission wheel is mounted on the reciprocating lead screw 82. The drive wheel and the transmission wheel are connected by a transmission belt. The transmission assembly 83 is used to drive the reciprocating lead screw 82 to rotate.

[0039] The rotating shaft 51 drives the reciprocating screw 82 to rotate through the transmission assembly 83. The reciprocating screw 82 drives the nut 85 and the movable frame 84 to move horizontally back and forth. The movable frame 84 drives the two pressure rollers 86 to move back and forth. The rolled copper strip 3 falls onto the support plate 81. The two pressure rollers 86 cooperate with the support plate 81 to roll the surface of the copper strip 3, effectively reducing the rolling texture on the surface of the copper strip 3, making the surface of the rolled copper strip 3 smoother and flatter, and improving the rolling effect of the copper strip 3. The rotating shaft 51 drives the reciprocating screw 82 to stop rotating through the transmission assembly 83. The reciprocating screw 82, the movable frame 84, the nut 85 and the pressure rollers 86 stop moving together.
