Battery Grid Trimming Patents (Class 83/903)
  • Patent number: 7007579
    Abstract: A method and apparatus for continuously producing pasted positive and negative electrode plates from pasted lead or lead alloy expanded, punched or cast metal mesh strip for use in lead-acid batteries without the use of paper barriers. The heating of cutting devices such as roll-mounted die-cutters to a predetermined temperature range of at least about 150° C., preferably about 160 to 300° C., and more preferably about 180 to 210° C., eliminates sticking of the paste on the pasted metal mesh strip to the cutting devices and obviates the need for the paper barriers.

  • Patent number: 4252042
    Abstract: A method and apparatus is described for feeding grid stock through a punch and die arrangement so that the spaced apart slots are equally spaced during the progression of the grid stock. The feed mechanism for strip stock comprises reciprocating punch means, die means associated with said reciprocating punch means to cooperate to punch out a group of spaced-apart slots in said strip stock, supporting means associated with said punch and die means to support said strip stock during its advance, a pair of members slidably mounted to said supporting means to operate on adjacent groups of spaced-apart slots in said strip stock to positively feed said stock away from said punch and die means, and means timed in respect to the reciprocation of said punch and die means and operative thereby, while said die means is raised from said punch means, to impart feeding movements to said feed stock.

  • Patent number: 4134318
    Abstract: A mechanism is provided in a battery grid casting machine for receiving grids one at a time from a grid trimming die and for arranging them in a horizontally stacked arrangement on a pair of pivoted rails. After a predetermined number of grids have accumulated on the rails, the rails are pivoted from a horizontal to a vertical position to deposit the grids as a vertical stack on an intermittently moving conveyor.

  • Patent number: 3949630
    Abstract: Battery grid plate castings are trimmed in a two-step operation. Each plate moves flat along a horizontal or inclined path against a first stop bar. One of two trim blades on a reciprocating upper die block then shears flashing from the leading end of the plate during a downward stroke of the die. Then the stop bar raises during the upward stroke of the die, and the plate moves forwardly against a second stop. Upon the next downward die stroke the second trim blade shears flashing from the trailing edge of the plate. During the next upward stroke, the fully trimmed plate moves forwardly onto a stacking device. As the leading end of one plate is trimmed at the first trim station, the trailing end of a preceding plate is trimmed at the second trim station. The second stop is easily moved to different stop positions along the path of travel of the plates to change the distance between such stop and the second trim blade and thereby enable trimming plates of different lengths without changing dies.
