Description

Technical Field

[0001] The utility model relates to the field of lead-acid battery manufacturing, in particular to a lead alloy grid burr removal device. Background Art

[0002] Lead-acid battery grid continuous casting technology, as the most economical and environmentally friendly grid production method at present, has been widely recognized by lead-acid battery manufacturers.

[0003] Lead-acid battery grids are produced using a continuous casting method. This method uses a rotating mold (rotating mold) and a fixed mold (fixed mold) to flush the lead liquid through the fixed mold into the cavity where the rotating mold and the fixed mold are in contact. After the rotating mold rotates away from the fixed mold, it cools and sets, and then the grid is pulled out. Due to the uncontrollable nature of casting itself, coupled with the machining errors and deformation differences after heating between the rotating mold and the fixed mold, the gap between the two is too large or the fit is uneven. The continuously cast lead-acid battery grid will have defects such as burrs and rough edges. This will affect the coating of lead paste during subsequent plate production and reduce the contact area between the lead paste and the grid, thereby affecting battery performance. At the same time, during the continuous casting process, lead oxide will gradually accumulate on the surface of the rotating mold. Foreign matter such as oil stains also affect the forming quality of the grid. The traditional method of removing burrs after the grid is cooled will make the burrs harder after cooling, making removal more difficult and the overall removal effect poor.

[0004] Therefore, in order to solve the above problems, a lead alloy grid burr removal device is needed to solve the above production problems. Utility Model Content

[0005] In view of this, the lead alloy grid burr removal device of the present technical solution is arranged between the grid exiting the fixed mold and the grid exiting the rotary mold, and adopts a rotating brush wheel method to rotate rapidly to remove the burrs and burrs generated on the surface of the grid. At the same time, it can also remove foreign matter such as lead oxide and oil accumulated on the surface of the rotary mold, thereby improving the surface quality of the grid and facilitating the subsequent product production.

[0006] A lead alloy grid burr removal device includes a burr removal mechanism arranged on a mold base plate, wherein the burr removal mechanism is arranged between the grid fixed mold and the grid traction roller, and the burr removal mechanism is used to cooperate with the grid to remove surface burrs.

[0007] Furthermore, the burr removal mechanism includes a positioning plate installed in conjunction with the mold substrate, a drive motor installed in conjunction with the positioning plate, and a wheel brush assembly installed on the mold substrate. The power output end of the drive motor is installed in conjunction with the wheel brush assembly and provides power input.

[0008] Furthermore, the wheel brush assembly includes a positioning seat arranged below the mold substrate, a wheel brush mounting seat installed in conjunction with the positioning seat, and a wheel brush shaft rotatably installed in conjunction with the wheel brush mounting seat, and the output end of the drive motor is connected and installed in conjunction with the wheel brush shaft.

[0009] Furthermore, a wheel brush is installed on the outer sleeve of the wheel brush shaft. The wheel brush includes a middle wheel brush and an outer wheel brush arranged in the middle of the wheel brush shaft. The outer wheel brush includes a left wheel brush and a right wheel brush arranged symmetrically with respect to the middle wheel brush.

[0010] Furthermore, the left wheel brush and the right wheel brush have the same structure, and the radius of the left wheel brush is larger than the radius of the middle wheel brush.

[0011] Furthermore, a coupling is provided between the wheel brush rotating shaft and the output shaft of the driving motor.

[0012] The beneficial effects of the utility model are:

[0013] 1. The installation position of the whole device should be between the grid leaving the fixed die and the grid leaving the rotating die. The burrs and burrs on the grid at this position have not been completely cooled and are easy to remove.

[0014] 2. The device should be positioned between the grid exiting the fixed die and separating from the rotary die. At this position, the grid body is embedded in the rotary die cavity and has not yet completely protruded from the outer circle of the rotary die. The burrs and burrs are outside the grid body and protrude from the outer circle of the rotary die. The grid body will not be damaged when removing the burrs and burrs.

[0015] 3. Because the burrs and burrs protrude from the outer circle of the rotating mold, the back of the grid has support, which makes it easier to remove. If there is no support, the burrs and burrs will be bent when the removal device is working, but it is not easy to brush off;

[0016] 4. Use the brush wheel method, which can better dynamically fit the outer circle of the rotating mold and better remove the burrs and burrs attached to the outer circle of the rotating mold;

[0017] 5. The wheel brush method can simultaneously remove foreign matter such as lead oxide and oil accumulated on the surface of the rotating mold, thereby improving product quality;

[0018] 6. When using the wheel brush method, you can replace the wheel brushes of different materials and structures according to the different grid alloys and forming states, including nylon brushes, wire brushes, etc., to achieve different rolling brush effects.

[0019] 7. The driving motor adopts a servo motor, which can match different speeds and directions according to requirements and roller brush effects, and realize forward and reverse rotation of the wheel brush at different speeds.

[0020] 8. The servo motor and the wheel brush are connected by an expansion sleeve coupling, which ensures the stability of the transmission and ensures that the wheel brush cuts off the power in the event of an abnormal jam, thereby protecting the rotating mold surface.

[0026] In this embodiment, the burr removal mechanism includes a positioning plate 8 mounted in conjunction with the mold base plate 1, a drive motor 7 mounted in conjunction with the positioning plate 8, and a wheel brush assembly mounted on the mold base plate 1. The power output end of the drive motor 7 is mounted in conjunction with the wheel brush assembly and provides power input. The positioning plate 8 is fixedly mounted on the side of the mold base plate 1 to provide a mounting position for the drive motor. The drive motor is a servo motor that can match different speeds and directions according to requirements and the roller brush effect, achieving forward and reverse rotation of the wheel brush at different speeds.

[0027] In this embodiment, the wheel brush assembly includes a positioning seat 9 provided below the mold substrate 1, a wheel brush mounting seat 10 mounted in conjunction with the positioning seat 9, and a wheel brush shaft 12 rotatably mounted in conjunction with the wheel brush mounting seat. The output end of the drive motor is connected and mounted in conjunction with the wheel brush shaft 12. The positioning seat 9 is fixedly mounted on the lower surface of the mold substrate 1, and the wheel brush mounting seat 10 is connected and mounted in conjunction with the positioning seat 9. The wheel brush mounting seats 10 are two mutually parallel arrangements for rotatably mounting the wheel brush shaft 12. The output end of the drive motor 7 provides power input to the wheel brush shaft 12.

The wheel brushes include a central wheel brush 13 positioned in the middle of the wheel brush shaft and outer wheel brushes. The outer wheel brushes include a left wheel brush and a right wheel brush 14 arranged symmetrically relative to the central wheel brush.

[0030] In this embodiment, a coupling 15 is provided between the wheel brush shaft and the output shaft of the drive motor. The expansion sleeve coupling is used to ensure the stability of the transmission and to cut off the power in the event of an abnormal jam of the wheel brush, thereby protecting the rotating mold surface.
