Description

Technical Field

[0001] The invention relates to the technical field of metal cutting, in particular to a slitting device for producing lead-acid battery plates. Background Art

[0002] Lead-acid batteries, as a type of energy storage element that can store more charges, are widely used in the field of vehicle engineering and are an indispensable starting source. There are multiple storage compartments inside the lead-acid battery, and two battery plates are arranged in each storage compartment. The existing battery plate manufacturing method usually comes from casting. Because the casting precision of the battery plate is not high, the surface quality of many cast plates is uneven. Although it does not affect the overall charging and discharging function, it will affect how many coulombs of charge can be stored in a single storage compartment. Therefore, in order to increase the weight of the lead-acid battery, engineers have to increase the manufacturing cost of the battery plate, that is, use metal plates with higher surface precision, and then cut them one by one. However, while improving the precision, it also reduces the production efficiency. Workers need to adjust the working conditions of the machine tool to adapt to the cutting of the metal plate, and constantly experiment and adjust between protecting the tool and improving the efficiency, wasting the energy of the operator. Summary of the invention

[0003] The object of the present invention is to provide a cutting device for producing lead-acid battery plates to solve the problems raised in the prior art.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a slitting device for producing lead-acid battery plates, comprising a cutting table, an adjustable cutting mechanism is arranged inside the cutting table, the adjustable cutting mechanism comprises an inner supporting slide rail, a chain transmission assembly, a crank slider assembly and a cutting machine, the crank slider assembly comprises a sliding table, the sliding table is slidably mounted on the inner supporting slide rail, the cutting machine is mounted on the sliding table, the cutting machine comprises a cutting motor and a saw blade, a pair of positioning rollers and an outer supporting slide rail are arranged above the cutting table, the pair of positioning rollers are arranged on both sides of the saw blade, a conveying mechanism is arranged on the outer supporting slide rail, and the conveying mechanism drives the battery plates to move.

[0005] Furthermore, two pairs of elastic support frames are arranged on the cutting table, and the two positioning rollers are respectively installed between the two pairs of elastic support frames, and the transmission mechanism includes a screw motor, a double-headed screw and a pair of sliders, and a pair of the sliders are slidably installed on the outer supporting slide rail, and the double-headed screw is respectively threadedly connected to a pair of sliders, and the two sections of the thread of the double-headed screw have opposite rotation directions, and the screw motor is arranged on the outside of the outer supporting slide rail, and the screw motor is coaxially connected to the double-headed screw. When the plate is cut, the elastic support frame presses the plate through the positioning rollers to prevent the plate from being displaced during the cutting process, thereby playing a role of clamping and fixing. The control system enables the screw motor to be energized and work, and the screw motor drives the double-headed screw to rotate. Since the two sections of the thread of the double-headed screw have opposite rotation directions, the two sliders move simultaneously driven by the double-headed screw, and move away from or close to each other when moving.

[0006] Furthermore, the transmission mechanism also includes an outer support arm, an inner support arm and a pair of hollow cup motors, the inner support arm passes through the middle of the outer support arm, the inner support arm is rotatably connected to the outer support arm, the length of the inner support arm is the same as that of the outer support arm, one end of the inner support arm is rotatably connected to a slider, and one end of the outer support arm is rotatably connected to another slider, the two sliders respectively drive the outer support arm and the inner support arm to move, the outer support arm and the inner support arm form an X-shaped connecting rod, when the two sliders approach each other, the other ends of the outer support arm and the inner support arm move away from each other and move backwards at the same time, and when the two sliders move away from each other, the other ends of the outer support arm and the inner support arm approach each other and move forward at the same time.

[0007] Furthermore, the two hollow cup motors are respectively arranged at one end of the inner support arm and the outer support arm away from the slider, the transmission mechanism includes a sliding shaft, a rotating hollow cylinder is installed in each of the hollow cup motors, the sliding shaft is slidably arranged in the rotating hollow cylinder, a spring is arranged between the sliding shaft and the rotating hollow cylinder for reset, a conical wheel is arranged on each sliding shaft, the conical surface of the conical wheel faces downward, and a detection wheel is installed at the bottom of each conical wheel.

When the conical wheel rotates and touches the plate, the conical surface squeezes the edge of the plate. Under the action of the squeezing force, the plate generates an upward component force on the conical wheel, and then the conical wheel rotates and slides upward, pushing the sliding shaft into the rotating hollow cylinder. The conical surface is squeezed into the plate at only one point, and the friction is too small to drive the plate to move. Until the detection wheel contacts the edge of the plate, the detection wheel and the plate are in line contact, and the friction increases, so the detection wheel can push the plate to move. At the same time, when the detection wheel detects that the edge is under force, the control system stops the screw motor, and the inner and outer arms stop moving. Then the hollow cup motor pushes the plate to move the appropriate length through the detection wheel, and the saw blade can cut the plate.

[0008] Furthermore, the tops of the two rotating hollow cylinders are connected with a switching oil pressure pipe, and the switching oil pressure pipe is rotatably and sealedly connected to the rotating hollow cylinder.

The narrower the width between the two detection wheels, the larger the space in the double-headed hydraulic cylinder, and the less hydraulic oil is distributed to the cavity connecting rod. The larger the width between the two detection wheels, the smaller the space in the double-headed hydraulic cylinder, and the more hydraulic oil is distributed to the cavity connecting rod. The thicker the plate, the higher the conical wheel will be pushed. Therefore, the less hydraulic oil is in the rotating hollow cylinder, and the more hydraulic oil is distributed to each small hydraulic cylinder. The thinner the plate, the smaller the movement amplitude of the conical wheel. Therefore, the more hydraulic oil is in the rotating hollow cylinder, and the less hydraulic oil is distributed to each small hydraulic cylinder.

If more hydraulic oil is distributed to each small hydraulic cylinder, the extended length of the piston rod increases, all the driven sprockets are farther away from the center of the mounting plate, the rotation radius of the mounting plate increases, the transmission ratio of the chain drive increases, and the rotation speed of the mounting plate decreases; if less hydraulic oil is distributed to each small hydraulic cylinder, the extended length of the piston rod is short, all the driven sprockets are closer to the center of the mounting plate, the rotation radius of the mounting plate decreases, the transmission ratio of the chain drive decreases, and the rotation speed of the mounting plate increases.

The faster the installation disk speed is, the thinner the plate is, and the saw blade accelerates the cutting of thin plates to save time. The slower the installation disk speed is, the slower the crank speed is, the crank drives the sliding table to slide slowly, and the cutting machine cuts the plate slowly. The slower the installation disk speed is, the thicker the plate is, and the saw blade cuts the thin plate slowly to protect the tool from damage, reduce the vibration caused by cutting, and improve the safety of the equipment.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0025] Example: Figure 1-Figure 8 As shown, the present invention provides a technical solution, a slitting device for producing lead-acid battery plates, including a cutting table 1, an adjustable cutting mechanism is arranged inside the cutting table 1, the adjustable cutting mechanism includes an inner supporting slide rail 14, a chain transmission assembly, a crank slider assembly and a cutting machine, the crank slider assembly includes a sliding table 15, the sliding table 15 is slidably mounted on the inner supporting slide rail 14, the cutting machine is mounted on the sliding table 15, the cutting machine includes a cutting motor 16 and a saw blade 17, a pair of positioning rollers 28 and an outer supporting slide rail 2 are arranged above the cutting table 1, a pair of positioning rollers 28 are arranged on both sides of the saw blade 17, and a conveying mechanism is arranged on the outer supporting slide rail 2, and the conveying mechanism drives the battery plates to move.

[0026] Two pairs of elastic support frames 29 are arranged on the cutting table 1, and two positioning rollers 28 are respectively installed between the two pairs of elastic support frames 29. The transmission mechanism includes a screw motor 3, a double-headed screw 4 and a pair of sliders 5. The pair of sliders 5 are slidably installed on the outer supporting slide rail 2, and the double-headed screw 4 is threadedly connected to the pair of sliders 5 respectively. The two sections of the thread of the double-headed screw 4 have opposite rotation directions. The screw motor 3 is arranged on the outer side of the outer supporting slide rail 2, and the screw motor 3 is coaxially connected to the double-headed screw 4. The transmission mechanism includes an outer support arm 6, an inner support arm 7 and a pair of hollow cup motors 8. The inner support arm 7 passes through the middle part of the outer support arm 6, and the inner support arm 7 is rotatably connected to the outer support arm 6. The length of the inner support arm 7 is the same as that of the outer support arm 6. One end of the inner support arm 7 is rotatably connected to one slider 5, and one end of the outer support arm 6 is rotatably connected to another slider 5.

[0027] When the plate is being cut, the elastic support frame 29 presses the plate through the positioning pressure roller 28 to prevent the plate from being displaced during the cutting process, thereby playing a role of clamping and fixing. The control system energizes the screw motor 3, and the screw motor 3 drives the double-headed screw 4 to rotate. Since the two sections of the thread of the double-headed screw 4 rotate in opposite directions, the two sliders 5 move simultaneously under the drive of the double-headed screw 4, and move away from or towards each other during movement. The two sliders 5 respectively drive the outer support arm 6 and the inner support arm 7 to move, and the outer support arm 6 and the inner support arm 7 form an X-shaped connecting rod. When the two sliders 5 approach each other, the other ends of the outer support arm 6 and the inner support arm 7 move away from each other and move backwards at the same time. When the two sliders 5 move away from each other, the other ends of the outer support arm 6 and the inner support arm 7 move towards each other and move forward at the same time.

[0028] Two hollow cup motors 8 are respectively arranged at one end of the inner support arm 7 and the outer support arm 6 away from the slider 5. The transmission mechanism includes a sliding shaft 10. A rotating hollow cylinder 9 is installed in each hollow cup motor 8. The sliding shaft 10 is slidably arranged in the rotating hollow cylinder 9. A spring is arranged between the sliding shaft 10 and the rotating hollow cylinder 9 for resetting. A conical wheel 11 is arranged on each sliding shaft 10, and the conical surface of the conical wheel 11 faces downward. A detection wheel 12 is installed at the bottom of each conical wheel 11. The tops of the two rotating hollow cylinders 9 are connected with a transfer oil pressure pipe 27, and the transfer oil pressure pipe 27 is rotatably sealed with the rotating hollow cylinder 9. The two transfer oil pressure pipes 27 connected to the rotating hollow cylinder 9 are merged into one. A double-headed hydraulic cylinder 13 is arranged between a pair of sliders 5, and a transfer oil pressure pipe 27 is also connected to the middle part of the double-headed hydraulic cylinder 13.

[0029] The plate to be cut is transported to the cutting table 1, and the screw motor 3 makes the ends of the outer support arm 6 and the inner support arm 7 provided with the hollow cup motor 8 approach each other, and the hollow cup motor 8 drives the rotating hollow cylinder 9 to rotate slowly, and the rotating hollow cylinder 9 drives the conical wheel 11 and the detection wheel 12 to rotate slowly at the same time through the sliding shaft 10. When the conical wheel 11 touches the plate while rotating, the conical surface squeezes the edge of the plate. Under the action of the squeezing force, the plate generates an upward component force on the conical wheel 11, and then the conical wheel 11 slides upward while rotating, pushing the sliding shaft 10 into the rotating hollow cylinder 9. The contact area between the conical surface and the plate is only a little, and the friction force is too small to drive the plate to move, until the detection wheel 12 contacts the edge of the plate, the detection wheel 12 is in line contact with the plate, and the friction force increases, so the detection wheel 12 can push the plate to move, and at the same time the detection wheel 1 2 When the edge force is detected, the control system stops the screw motor 3, the inner arm 7 and the outer arm 6 stop moving, and then the hollow cup motor 8 pushes the plate to move a suitable length through the detection wheel 12, and the saw blade 17 can cut the plate. The narrower the width between the two detection wheels 12, the larger the space in the double-headed hydraulic cylinder 13, and the less hydraulic oil is distributed to the cavity connecting rod 18. The larger the width between the two detection wheels 12, the smaller the space in the double-headed hydraulic cylinder 13, and the more hydraulic oil is distributed to the cavity connecting rod 18. The thicker the plate, the higher the conical wheel 11 will be pushed. Therefore, the less hydraulic oil is in the rotating hollow cylinder 9, and the more hydraulic oil is distributed to each small hydraulic cylinder 22. The thinner the plate, the smaller the movement of the conical wheel 11. Therefore, the more hydraulic oil is in the rotating hollow cylinder 9, and the less hydraulic oil is distributed to each small hydraulic cylinder 22.

[0030] The chain drive assembly includes a mounting plate 21 and a plurality of small hydraulic cylinders 22. The mounting plate 21 is installed through a bracket. The plurality of small hydraulic cylinders 22 are evenly installed on the mounting plate 21. A driven sprocket 23 is fixedly provided on the piston rod of each small hydraulic cylinder 22. A circular hole is provided in the middle of the mounting plate 21. The interior of each small hydraulic cylinder 22 is connected to the circular hole through a pipeline. The circular hole is rotatably sealed and connected to a transfer oil pressure pipe 27 that is collected into one. The chain drive assembly includes a chain 24, a driving sprocket 25 and a transmission motor 26. The driving sprocket 25 is installed on the motor shaft of the transmission motor 26. The chain 24 is connected between the driving sprocket 25 and the plurality of driven sprockets 23. A swing arm (not shown in the figure) is rotatably provided at the bottom of the cutting table 1. A tensioning sprocket (not shown in the figure) is rotatably provided at one end of the swing arm. The tensioning sprocket is also engaged with the chain 24.

[0031] The transmission motor 26 drives the active sprocket 25 to rotate, and the active sprocket 25 drags the installation plate 21 to rotate through the meshing of the chain 24 and the driven sprocket 23. If more hydraulic oil is distributed to each small hydraulic cylinder 22, the length of the piston rod extension increases, all the driven sprockets 23 are farther away from the center of the installation plate 21, the rotation radius of the installation plate 21 increases, the transmission ratio of the chain drive increases, and the rotation speed of the installation plate 21 decreases. If less hydraulic oil is distributed to each small hydraulic cylinder 22, the length of the piston rod extension is short, all the driven sprockets 23 are closer to the center of the installation plate 21, the rotation radius of the installation plate 21 decreases, the transmission ratio of the chain drive decreases, and the rotation speed of the installation plate 21 increases. Even if the rotation radius of the installation plate 21 changes, the chain 24 is under tension. Under the action of the tightening sprocket, the tension will not be sometimes loose and sometimes tight, but will maintain an appropriate degree of tension. The mounting disk 21 is the power source that drives the crank 20 to rotate. The faster the speed of the mounting disk 21 is, the faster the speed of the crank 20 is. The crank 20 drives the sliding table 15 to slide quickly, and the cutting machine cuts the plate quickly. The faster the speed of the mounting disk 21 is, the thinner the plate is. The saw blade 17 can accelerate the cutting of the thin plate to save time. The slower the speed of the mounting disk 21 is, the slower the speed of the crank 20 is. The crank 20 drives the sliding table 15 to slide slowly, and the cutting machine cuts the plate slowly. The slower the speed of the mounting disk 21 is, the thicker the plate is. The saw blade 17 can protect the tool from damage by cutting the thin plate slowly, reduce the vibration caused by cutting, and improve the safety of the equipment.

[0032] The crank slider assembly includes a cavity connecting rod 18, a sleeve connecting rod 19 and a crank 20. The crank 20 is coaxially arranged with the mounting plate 21. The sleeve connecting rod 19 is rotatably connected with the crank 20. The cavity connecting rod 18 is rotatably connected with the bottom of the sliding platform 15. The sleeve connecting rod 19 is slidably installed in the cavity connecting rod 18. One end of the adapter oil pressure pipe 27 connected to the double-headed hydraulic cylinder 13 is connected to the cavity connecting rod 18. The adapter oil pressure pipe 27 is connected to the inside of the cavity connecting rod 18. The less hydraulic oil is distributed to the cavity connecting rod 18, the shorter the length of the combination of the cavity connecting rod 18 and the sleeve connecting rod 19, and the shorter the reciprocating sliding stroke of the sliding platform 15. The more hydraulic oil is distributed to the cavity connecting rod 18, the longer the length of the combination of the cavity connecting rod 18 and the sleeve connecting rod 19, and the longer the reciprocating sliding stroke of the sliding platform 15. The present invention uses a transmission mechanism to align the plate The thickness and width of the material, the thickness of the plate is fed back by the amount of hydraulic oil squeezed into the small hydraulic cylinder 22 by rotating the hollow cylinder 9. The thinner the plate, the faster the saw blade 17 cuts the thin plate to save time. The thicker the plate, the slower the saw blade 17 cuts the thin plate to protect the tool from damage, reduce the vibration caused by cutting, and improve the safety of the equipment. The width of the plate is fed back by the amount of hydraulic oil entering and exiting the hollow connecting rod 18 by the double-headed hydraulic cylinder 13. The narrower the plate, the shorter the length of the connecting rod combination, and the shorter the reciprocating sliding stroke of the sliding table 15. The wider the plate, the longer the length of the connecting rod combination, and the longer the reciprocating sliding stroke of the sliding table 15. This further saves cutting time, avoids useless empty strokes, improves the cutting efficiency of the equipment, and realizes the function of adjusting the cutting conditions according to the width and thickness of the plates.

[0033] The working principle of the present invention is as follows: when the plate is being cut, the elastic support frame 29 presses the plate through the positioning pressure roller 28 to prevent the plate from being displaced during the cutting process, thereby playing a role of clamping and fixing. The control system energizes the screw motor 3 to work, and the screw motor 3 drives the double-headed screw 4 to rotate. Since the two sections of the thread of the double-headed screw 4 have opposite rotation directions, the two sliders 5 move simultaneously under the drive of the double-headed screw 4, and move away from or towards each other during movement. The two sliders 5 respectively drive the outer support arm 6 and the inner support arm 7 to move, and the outer support arm 6 and the inner support arm 7 form an X-shaped connecting rod. When the two sliders 5 approach each other, the other ends of the outer support arm 6 and the inner support arm 7 move away from each other and move backward at the same time. When the two sliders 5 move away from each other, the other ends of the outer support arm 6 and the inner support arm 7 move towards each other and move forward at the same time.

[0034] The plate to be cut is transported to the cutting table 1, and the screw motor 3 makes the ends of the outer support arm 6 and the inner support arm 7 provided with the hollow cup motor 8 approach each other, and the hollow cup motor 8 drives the rotating hollow cylinder 9 to rotate slowly, and the rotating hollow cylinder 9 drives the conical wheel 11 and the detection wheel 12 to rotate slowly at the same time through the sliding shaft 10. When the conical wheel 11 touches the plate while rotating, the conical surface squeezes the edge of the plate. Under the action of the squeezing force, the plate generates an upward component force on the conical wheel 11, and then the conical wheel 11 slides upward while rotating, pushing the sliding shaft 10 into the rotating hollow cylinder 9. The contact area between the conical surface and the plate is only a little, and the friction force is too small to drive the plate to move, until the detection wheel 12 contacts the edge of the plate, the detection wheel 12 is in line contact with the plate, and the friction force increases, so the detection wheel 12 can push the plate to move, and at the same time the detection wheel 1 2 When the edge force is detected, the control system stops the screw motor 3, the inner arm 7 and the outer arm 6 stop moving, and then the hollow cup motor 8 pushes the plate to move a suitable length through the detection wheel 12, and the saw blade 17 can cut the plate. The narrower the width between the two detection wheels 12, the larger the space in the double-headed hydraulic cylinder 13, and the less hydraulic oil is distributed to the cavity connecting rod 18. The larger the width between the two detection wheels 12, the smaller the space in the double-headed hydraulic cylinder 13, and the more hydraulic oil is distributed to the cavity connecting rod 18. The thicker the plate, the higher the conical wheel 11 will be pushed. Therefore, the less hydraulic oil is in the rotating hollow cylinder 9, and the more hydraulic oil is distributed to each small hydraulic cylinder 22. The thinner the plate, the smaller the movement of the conical wheel 11. Therefore, the more hydraulic oil is in the rotating hollow cylinder 9, and the less hydraulic oil is distributed to each small hydraulic cylinder 22.

[0035] The transmission motor 26 drives the active sprocket 25 to rotate, and the active sprocket 25 drags the installation plate 21 to rotate through the meshing of the chain 24 and the driven sprocket 23. If more hydraulic oil is distributed to each small hydraulic cylinder 22, the length of the piston rod extension increases, all the driven sprockets 23 are farther away from the center of the installation plate 21, the rotation radius of the installation plate 21 increases, the transmission ratio of the chain drive increases, and the rotation speed of the installation plate 21 decreases. If less hydraulic oil is distributed to each small hydraulic cylinder 22, the length of the piston rod extension is short, all the driven sprockets 23 are closer to the center of the installation plate 21, the rotation radius of the installation plate 21 decreases, the transmission ratio of the chain drive decreases, and the rotation speed of the installation plate 21 increases. Even if the rotation radius of the installation plate 21 changes, the chain 24 is under tension. Under the action of the tightening sprocket, the tension will not be sometimes loose and sometimes tight, but will maintain an appropriate degree of tension. The mounting disk 21 is the power source that drives the crank 20 to rotate. The faster the speed of the mounting disk 21 is, the faster the speed of the crank 20 is. The crank 20 drives the sliding table 15 to slide quickly, and the cutting machine cuts the plate quickly. The faster the speed of the mounting disk 21 is, the thinner the plate is. The saw blade 17 can accelerate the cutting of the thin plate to save time. The slower the speed of the mounting disk 21 is, the slower the speed of the crank 20 is. The crank 20 drives the sliding table 15 to slide slowly, and the cutting machine cuts the plate slowly. The slower the speed of the mounting disk 21 is, the thicker the plate is. The saw blade 17 can protect the tool from damage by cutting the thin plate slowly, reduce the vibration caused by cutting, and improve the safety of the equipment.

[0036] The less hydraulic oil is distributed to the cavity connecting rod 18, the shorter the length of the combination of the cavity connecting rod 18 and the sleeve connecting rod 19, and the shorter the reciprocating sliding stroke of the sliding table 15. The more hydraulic oil is distributed to the cavity connecting rod 18, the longer the length of the combination of the cavity connecting rod 18 and the sleeve connecting rod 19, and the longer the reciprocating sliding stroke of the sliding table 15. The present invention uses a transmission mechanism to measure the thickness and width of the plate. The thickness of the plate is fed back by the amount of hydraulic oil squeezed into the small hydraulic cylinder 22 by rotating the hollow cylinder 9. The thinner the plate, the faster the saw blade 17 can cut the thin plate, which can save time. The thicker the plate, The slow cutting of thin plates by the saw blade 17 can protect the tool from damage, reduce the vibration caused by cutting, and improve the safety of the equipment. The width of the plate is fed back by the amount of hydraulic oil entering and exiting the cavity connecting rod 18 through the double-headed hydraulic cylinder 13. The narrower the plate, the shorter the length of the connecting rod combination, and the shorter the reciprocating sliding stroke of the sliding table 15; the wider the plate, the longer the length of the connecting rod combination, and the longer the reciprocating sliding stroke of the sliding table 15, further saving cutting time, avoiding useless idle strokes, improving the cutting efficiency of the equipment, and realizing the function of adjusting the cutting conditions according to the width and thickness of different plates.
