3rd step, starts forcing press opponent's brake control rod right member(6)With hand braking control-rod left member(7)Carry out punch process, Workbench is with forming convax mould on lathe(5)Move downward, work as forming convax mould(5)With hand braking control-rod right member(6)And hand Brake control rod left member(7)During contact, bottom knockout block(12), bottom knockout bar(18)With ejector top board(19)With excellent power rubber Glue(20)The upward thrust and hand braking control-rod right member produced by compression(6)With hand braking control-rod left member(7)Together with Forming convax mould(5)Move downward, when hand braking control-rod right member(6)With hand braking control-rod left member(7)It is recessed with left and right two pieces Mould embeds disk roller(10)During contact, two pieces cavity plate embeds disk roller(10)Synchronously in molding concave die(11)Rolling makes hand braking in inner chamber Control-rod right member(6)With hand braking control-rod left member(7)Stable entrance left and right two pieces molding concave die(11)In the die cavity of formation, Until bottom knockout block(12)Lower surface touch lower bolster(13)Upper surface untill, make hand braking control-rod right member(6)With Hand braking control-rod left member(7)In forming convax mould(5), molding concave die(11), cavity plate embed disk roller(10)With bottom knockout block(12) Between die cavity in complete the brake forming of U-shaped hook;
4th step, forcing press upper table face and forming convax mould(5)First return, then ejector top board upwards(19)With excellent Power rubber(20)Because compressing the upward thrust produced by bottom knockout bar(18), bottom knockout block(12), hand braking control-rod right member (6)With hand braking control-rod left member(7)Upward jack-up, until ejector top board(19)Upper surface and lower template(17)Under Untill surface is in contact, hand is adsorbed by the good hand braking control-rod right member of brake forming with long handle(6)It is left with hand braking control-rod Part(7)From die block(9)And molding concave die(11)Upper surface on be removed and placed in body feed tank.
