Description

Technical Field

[0001] This invention belongs to the field of lead-acid battery manufacturing technology, and in particular relates to a lead strip billet continuous casting machine. Background Technology

[0002] Currently, in the lead-acid battery industry, grid manufacturing is mainly achieved through continuous casting and rolling processes. The mainstream equipment is a double-roll continuous casting and rolling mill, whose core structure consists of a pair of large rotating forming rolls with built-in cooling systems and side sealing plates with heating devices, which together form an inverted conical molten pool cavity.

[0003] The lead crystallization process in mainstream equipment has significant drawbacks. As the principle of metal solidification states, rapid solidification refines grains and improves the mechanical properties of the material; while slow crystallization leads to coarse grains and degraded performance. During operation, the molten pool of the roller mill is enormous (approximately 36,000 cm³), and the side sealing plates require continuous heating (250-300℃) to prevent solidification of the lead. This results in the lead alloy being in a state of slow crystallization throughout the entire process, which is detrimental to obtaining high-strength, highly corrosion-resistant grid materials. Secondly, the equipment is bulky and economically inefficient. The industry-standard roller diameter reaches 1200 mm, the entire machine weighs approximately 20 tons, and the rollers require high-strength alloy tempered steel, resulting in high material costs.

[0004] Therefore, it is necessary to design a lead strip billet continuous casting machine to solve the above problems. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1 to 8 As shown, the present invention provides a lead strip billet continuous casting machine, comprising: Rack 5; The lead-injection device 6 is fixedly installed at the top of the frame 5. The lead-injection device 6 is used to transport the molten lead from the lead-melting furnace. Vibrator 2 is fixedly mounted on frame 5; Crystallizer 1 is fixedly mounted on vibrator 2. Crystallizer 1 is located below the outlet end of lead molten metal device 6. Crystallizer 1 is used to crystallize and solidify lead molten metal into lead strip blanks. Vibrator 2 is used to drive crystallizer 1 to vibrate so that the lead strip blanks are separated from crystallizer 1. Cooling device 4 is installed on frame 5. Cooling device 4 is used to provide circulating cooling water to crystallizer 1 so that crystallizer 1 crystallizes and solidifies lead water into lead strip blank. The traction device 3 is installed inside the frame 5. The traction device 3 is located below the discharge port of the crystallizer 1. The traction device 3 is used to pull the lead strip billet out of the crystallizer 1.

[0030] The crystallizer 1 is mounted on the vibrating arm 19 of the vibrator 2. Its main function is to transform molten lead into a solid billet with preliminary strength and shape through precise cooling and shape control, while laying a quality foundation for subsequent processes (secondary cooling, straightening, and cutting).

[0031] The upper part of the crystallizer 1 is a molten pool with a heating device; the lower part is a crystallization chamber mainly composed of copper alloy, and the size of the inner cavity of the crystallization chamber is the required slab size. The molten pool only serves as a container for molten lead and does not participate in the crystallization process. There is a cooling device 4 on the back side of the crystallization chamber of the crystallizer 1. The molten lead flowing into the crystallization chamber is rapidly crystallized and solidified into a solid slab under the action of the cooling device 4.

[0032] The main function of vibrator 2 is to precisely control the vibration parameters (frequency, amplitude, waveform, etc.) of crystallizer 1. The vibration of vibrator 2 solves the problem of the billet shell sticking to the inner wall of crystallizer 1 during the solidification of lead molten lead, thus ensuring the stability of the continuous casting process and the quality of the cast billet.

[0033] The main function of the traction device 3 is to provide a continuous and stable traction force for the solidified billet in the crystallizer 1, overcome the movement resistance of the billet in the crystallizer 1, ensure that the billet is pulled out uniformly at the set speed, and finally form a solid lead billet that meets the requirements.

[0034] The main function of the cooling device 4 is to provide circulating cooling water to the crystallizer 1 so that the crystallizer 1 can crystallize liquid lead into solid lead billets.

[0035] The frame 5, as the skeleton of the mechanical equipment, mainly serves to bear the main components, support the machine's operation, increase stability, protect the equipment's safety, bear weight, and support the equipment.

[0036] The molten lead from the lead-smelting furnace is transported to the lead-injection device 6 through a pump system and a pipeline system. The molten lead is injected into the crystallizer 1, where it crystallizes and solidifies into a lead strip blank. Under the vibration of the vibrator 2, the lead strip blank separates from the inner wall of the crystallizer 1. The lead strip blank is then pulled out evenly at a set speed by the traction device 3, ultimately forming a solid lead strip blank that meets the requirements.

[0037] Furthermore, the crystallizer 1 includes a molten pool, which is fixedly connected to the vibrator 2. The large end of the molten pool faces upward and the small end faces downward. The large end of the molten pool is located below the outlet end of the lead-injection water device 6. A crystallization chamber is provided below the small end of the molten pool, and the cooling device 4 provides circulating cooling water to the crystallization chamber.

[0038] Furthermore, the molten pool includes two vertical molten pool plates 13, which are vertically and parallelly spaced apart. The vertical molten pool plates 13 are fixedly connected to the vibrating arm 19 in the vibrator 2. The side walls of the two vertical molten pool plates 13 that are close to each other are respectively provided with molten pool inclined plates 14. The top of the molten pool inclined plates 14 is fixedly connected to the side wall of the vertical molten pool plate 13. The bottom ends of the two molten pool inclined plates 14 are provided with width adjustment strips 12 on both sides. The top ends of the two molten pool inclined plates 14 are far apart from each other to form the large opening end of the molten pool, and the bottom ends of the two molten pool inclined plates 14 are close to each other to form the small opening end of the molten pool. The left and right ends of the vertical molten pool plate 13 and the molten pool inclined plates 14 are fixedly connected with side sealing plates 15.

[0039] Furthermore, the crystallization chamber includes a fixed-side copper plate 7 and a movable-side copper plate 9, which are spaced apart. The gap between the fixed-side copper plate 7 and the movable-side copper plate 9 is located below the bottom of the two molten pool inclined plates 14. A fixed-side copper plate back plate 8 is fixedly connected to the side wall of the fixed-side copper plate 7 away from the movable-side copper plate 9. The fixed-side copper plate back plate 8 is fixedly connected to the side sealing plate 15. The movable-side copper plate 9 is movably connected to the side sealing plate 15. A movable-side copper plate back plate 10 is fixedly connected to the side wall of the movable-side copper plate 9 away from the fixed-side copper plate 7. The cooling device 4 is fixedly connected to the fixed-side copper plate back plate 8 and the movable-side copper plate back plate 10.

[0040] Furthermore, the cooling device 4 includes a cooling system 11, which includes a cold water inlet and a hot water outlet. One end of the cold water inlet is connected to a cold water source, and the other end of the cold water inlet is fixedly connected to the fixed side copper plate back plate 8 and the movable side copper plate back plate 10. The end of the hot water outlet is fixedly connected to the fixed side copper plate back plate 8 and the movable side copper plate back plate 10.

[0041] The molten pool includes a heating device and a temperature measuring device. The heating device is used to heat the molten lead injected into the molten pool from the lead injection device 6, and the temperature measuring device is used to detect the heating temperature of the heating device so as to regulate and control the heating temperature of the heating device in an open-loop or closed-loop manner.

[0042] The molten pool serves only as a container for molten lead; the molten lead in the pool does not participate in the crystallization process.

[0043] The crystallization cavity is located at the bottom of the crystallizer 1. It is composed of a fixed side copper plate 7, a movable side copper plate 9, a side sealing plate 15, and a width adjustment strip 12, forming an approximately rectangular cavity. Since the solidification of metal crystals will cause shrinkage, the crystallization cavity is slightly inverted conical, that is, the upper opening is slightly larger than the lower opening.

[0044] The fixed-side copper plate 7 and the fixed-side copper plate back plate 8 are assembled together to form the fixed-side crystallizer plate; the movable-side copper plate 9 and the movable-side copper plate back plate 10 are assembled together to form the movable-side crystallizer plate. The fixed-side crystallizer plate is relatively fixed, while the movable-side crystallizer plate can be adjusted by adjusting bolts or lead screws to control the thickness of the lead strip blank. There is a cooling water heat dissipation groove between the copper plate and the back plate to achieve the purpose of cooling the heat dissipation crystallizer 1 of the cooling device 4.

[0045] Due to the harsh working conditions of crystallizer 1, the copper plate material is required to have good tensile strength, fatigue strength, hardness, low elongation, and high thermal conductivity within the temperature range of 0-400℃. The copper alloy plate of this invention undergoes overall heat treatment to eliminate internal stress, improve thermal conductivity, increase strength, and enhance its wear resistance and corrosion resistance. The working surface undergoes surface treatment (such as chrome plating, nickel-chromium alloy plating, or ceramic plating) to increase surface smoothness, corrosion resistance, and hardness.

[0046] The width of the lead strip blank is mainly adjusted by the width adjustment strip 12. The width of the lead strip blank can be adjusted by changing the width adjustment strip 12 of different sizes.

[0047] The crystallization chamber is the core functional part of the crystallizer 1. The liquid lead in the molten pool flows into the crystallization chamber. Because the crystallization chamber is a thin plate, under the action of the cooling device 4, and because the main body of the crystallizer 1 is a copper alloy plate with high heat dissipation, the liquid lead can achieve rapid crystallization in the crystallization chamber.

[0048] The cooling system 11 mainly provides cold water circulation for the crystallizer 1 to achieve heat dissipation. The hoses used in the cooling system 11 adopt quick-connect couplings for easy insertion, removal, and maintenance.

[0049] Furthermore, the vibrator 2 includes a vibration support 16, which is fixedly connected to the frame 5. A vibration part is fixedly connected to the vibration support 16, and the output end of the vibration part is fixedly connected to the crystallization chamber.

[0050] Furthermore, the vibration unit includes a first motor 20, which is fixedly connected to the vibration bracket 16. The output shaft of the first motor 20 is fixedly connected to an eccentric transmission main shaft 21. An eccentric sleeve 22 is fixedly sleeved on the outside of the eccentric transmission main shaft 21. The eccentric sleeve 22 is connected to a long transmission arm 17 via a connecting rod and a shaft. The middle part of the long transmission arm 17 is rotatably connected to the vibration bracket 16. There are two long transmission arms 17. The other end of the long transmission arm 17 is provided with a vibration arm 19. The two vibration arms 19 are fixedly connected to the crystallization chamber. One end of the vibration arm 19 is also rotatably connected to a short transmission arm 18. The other end of the short transmission arm 18 is rotatably connected to the vibration bracket 16. The short transmission arm 18 is located above the long transmission arm 17.

[0051] A buffer leaf spring 23 is provided between the vibration support 16 and the vibration arm 19.

[0052] The vibration bracket 16 is connected to the frame 5. It is the main component that bears and supports the vibration unit.

[0053] The vibration patterns of crystallizer 1 mainly fall into three categories: rectangular velocity pattern, trapezoidal velocity pattern, and sinusoidal velocity pattern.

[0054] Among them, the sinusoidal velocity vibration law is a relatively ideal vibration law, for the following reasons: ①Since the velocity changes according to a sine curve, the acceleration changes according to a cosine curve, making the crystallizer 1 vibrate more smoothly.

[0055] ② Due to the smaller acceleration, a higher vibration frequency can be used, which helps to eliminate the adhesion of the blank shell and improve the demolding effect.

[0056] ③ Sinusoidal vibration can be easily achieved through electronic or mechanical eccentric mechanisms, and is easy to manufacture, has high motion accuracy, and is easy to use for high-frequency vibration.

[0057] The eccentricity of this invention is achieved through an eccentric drive main shaft 21 and an eccentric sleeve 22. The eccentricity can be infinitely adjusted via the eccentric drive main shaft 21 or the eccentric sleeve 22. Alternatively, sinusoidal vibration can be achieved through a servo cylinder and a programmed electronic eccentric wheel mechanism.

[0058] The first motor 20, eccentric drive shaft 21, eccentric sleeve 22, long drive arm 17, and short drive arm 18 form a four-bar linkage sinusoidal vibration transmission mechanism, thereby realizing the regular up-and-down vibration of the vibrating arm 19. Since the crystallizer 1 is fixed on the vibrating arm 19, the crystallizer 1 achieves sinusoidal up-and-down vibration. Among them, the first motor 20 adopts frequency conversion control, which is matched with the open-loop or closed-loop control of the traction speed of the traction device 3 to ensure smooth separation of the lead strip blank from the inner wall of the crystallizer 1. The traction device 3 then pulls the lead strip blank out evenly at the set speed, ultimately forming a solid lead strip blank that meets the requirements.

[0059] The buffer leaf spring 23 mainly serves the following functions: offsetting part of the gravity applied to the traction device 3 by the crystallizer 1; reducing the impact of dynamic load on the reducer during vibration; and improving the anti-polarization capability of the vibrator 2 during vibration.

[0060] Furthermore, the traction device 3 includes a traction bracket, which is fixedly connected to the frame 5. The traction bracket is provided with a traction drive part and a traction clamping part, and there is a gap between the traction drive part and the traction clamping part, which is adapted to the lead strip blank.

[0061] Furthermore, the traction drive unit includes a lower transmission roller 24, an upper fixed roller 25, and an intermediate shaft. Both the lower transmission roller 24 and the upper fixed roller 25 are rotatably connected to the traction bracket. The intermediate shaft is fixedly connected to the traction bracket and located between the lower transmission roller 24 and the upper fixed roller 25. One end of the lower transmission roller 24 is coaxially fixedly connected to the output shaft of the second motor 29. The second motor 29 is fixedly connected to the traction bracket. The other end of the lower transmission roller 24 is fixedly fitted with a transmission roller gear. The transmission roller gear meshes with an intermediate gear 28. The intermediate gear 28 is rotatably connected to the intermediate shaft through a bearing. The intermediate gear 28 also meshes with a fixed roller gear. The fixed roller gear is fixedly connected to the upper fixed roller 25.

[0062] Furthermore, the traction clamping part includes an upper clamping cylinder 30 and a lower clamping cylinder 31. The cylinder ends of the upper clamping cylinder 30 and the lower clamping cylinder 31 are fixedly connected to the traction bracket. The piston ends of the upper clamping cylinder 30 and the lower clamping cylinder 31 are fixedly connected to a movable clamping frame. A lower movable roller 26 and an upper movable roller 27 are rotatably connected to the movable clamping frame. The lower movable roller 26 corresponds to the lower transmission roller 24, and the upper movable roller 27 corresponds to the upper fixed roller 25. The movable roller gear at the end of the upper movable roller 27 meshes with the movable roller gear at the end of the lower movable roller 26 through an intermediate gear 28. The intermediate gear 28 is rotatably mounted on the movable clamping frame.

[0063] The traction bracket is also equipped with a guide mechanism 32.

[0064] To increase the friction between the roller surface and the lead casting, all roller surfaces in contact with the lead casting were knurled.

[0065] The second motor 29 can be frequency-controlled to adjust the rotation speed, and can be used to control the speed of the clamping roller of the traction device 3 in an open-loop or closed-loop manner in conjunction with the vibration frequency of the vibrator 2, thereby controlling the speed at which the traction device 3 pulls the lead strip blank.

[0066] The main function of the guide mechanism 32 is to prevent the lead strip blank from deviating during the traction process. The position of the guide mechanism 32 can be adjusted by the long screw connected to the traction bracket.
