Device for casting electrode supports for lead-acid batteries

Abstract

A device for casting electrode carriers for the production of lead grid electrodes in a continuous casting process is provided, which includes a casting drum, the surface of which has been engraved with the shape of the lead strip to be cast, and a casting shoe which rests on the outer circumference of the casting drum in the region of the horizontal axis drawn through the axis of rotation when the casting drum rotates counterclockwise, whereat the exiting liquid lead flows into the concave mold of the casting drum surface and is removable as a solidified lead strip at the lower vertex of the casting drum after three quarters of a rotation and whereat draft angles of less than 7 degrees, in particular less than 3 degrees are provided.

1 . A device for casting electrode carriers for the production of lead grid electrodes in a continuous casting process, comprising:
 (a) a casting drum having a draft angle of less than 7 degrees, the surface of which has been engraved with the shape of a lead grid strip to be cast, and   (b) a casting shoe positioned on the outer circumference of the casting drum,   wherein during rotation of the casting drum an exiting liquid lead flows into a concave mold of the casting drum surface and is removable as a solidified lead grid strip at a lower vertex of the casting drum after less than one turn of a rotation of the casting drum, and   wherein after about a three quarter turn of the casting drum, the lead grid strip is withdrawable at a lower vertex only by mean of the force of gravity acting perpendicular on the lead grid strip and releasing the lead grid strip from the casting durm having the draft draft angles of less than 7 degrees.   
     
     
         2 . The device according to  claim 1 , wherein a vacuum device is provided for removing the lead strip. 
     
     
         3 . The device according to  claim 1 , wherein a blowing device is provided for removing the lead strip, which blows compressed air between a cast grid belt and the cast drum engraving. 
     
     
         4 . The device according to  claim 1 , wherein a vibration device is provided for removing the lead strip. 
     
     
         5 . The device according to  claim 2 , wherein the device additionally comprises a vacuum device comprises a vacuum belt. 
     
     
         6 . The device according to  claim 5 , wherein the vacuum belt features a hole pattern that is adapted to the grid structure of the lead grid strip. 
     
     
         7 . The device according to  claim 1 , wherein a hammer device is provided in the area of the removal point, which applies hammer blows to the casting drum at a predetermined frequency. 
     
     
         8 . The device according to  claim 1 , wherein a guide plate is provided above the removed lead grid strip at the vertex point, which supports demolding. 
     
     
         9 . The device according to  claim 1 , wherein the lead grid strip is moving throw a pair of a sand lapping jets located and working against each other. 
     
     
         10 . The device of  claim 1 , wherein the draft angle is less than 3 degrees.
