Description
CAN BODY MAKING APPARATUS
This invention relates generally to a can body making apparatus and more particularly to an improvement in the ram assembly apparatus for maintaining more accurate alignment of the ram during the reciprocation thereof and in the redraw apparatus for providing and maintaining more accurate alignment of the can blanks with the ram and the tool pack containing the can forming and ironing dies.
A can body making apparatus is disclosed in U.S. Patent No. 3,696,657. The ram carriage and redraw carriage are each mounted on rollers which move over carriage way strips. Each pair of upper and lower rollers are urged toward each other so as to be in firm contact with the carriage way strip located therebetween. Both the ram and redraw carriages are reciprocated at rates sufficient to form about two hundred cans a minute. The constant reciprocal movement of the ram and redraw carriages and the tight engagement of the rollers on the carriage way strips result in wear which causes misalignment of the ram or of the can blanks by the redraw sleeve. It is understood that this misalignment is small, between about o.oos and O.olo of an inch, but such misalignment can result in defective cans.
This invention provides ram assembly means _, ~
~ 336247 ~for a can body making apparatus wherein ram means are mounted on ram carriage means which have a pair of liquid bearing means for mounting the ram carriage means for reciprocal movement over a pair of fixedly 5 mounted, spaced apart, elongated shafts. Also, guide means, such as liquid bearing means, are provided for guiding the reciprocal movement of the ram means therethrough.
This invention also provides a redraw apparatus for a can body making apparatus wherein the redraw carriage is slidably mounted on a pair of spaced apart support posts for reciprocal movement thereover, which support posts are fixedly mounted on the housing holding the can forming and ironing dies.
The invention also provides counterbalancing means for supporting at least a major portion of the weight of the redraw actuating rod, also known as the push rod, to substantially eliminate the weight on the carriage sleeve for more efficient operation.
In the preferred embodiment of the invention, ram assembly means are provided for a can body making apparatus having means for reciprocating a ram carriage means and a ram means along their longitudinal axes so that the ram means push a can blank through can forming and ironing dies to form a can body. The ram assembly means include a pair of spaced apart, elongated shafts having generally cylindrical outer surfaces and which are fixedly mounted on a fixed frame means. The ram means are mounted on a ram carriage means that have a pair of spaced apart liquid bearing means each having a cylindrical inner surface for reciprocal movement over the elongated shafts. The liquid bearing means has a plurality of arcuately shaped pocket means, each of which is supplied with a liquid, preferably from the coolant supply of the can body making apparatus, at suitable pressures. Each liquid bearing means also _ _ 3 _ ~as iiquid return means for removing the liquid supplied to the pocket means. Guide means, preferably comprising liquid bearing means, are fixedly mounted on the frame means and are located so that the ram means are supported for reciprocal movement therethrough. A redraw carriage including a redraw sleeve is located between the ram assembly means and the can forming and ironing dies and functions to hold a can blank in the proper position against the can forming and ironing dies 80 that the ram means will push the can blank through the can forming and ironing dies to form a can body. The redraw apparatus includes a redraw carriage that is provided with a pair of spaced apart bearings having generally cylindrical inner surfaces. A pair of spaced apart support posts are fixedly mounted on the housing holding the can forming and ironing dies and have generally cylindrical outer surfaces. The redraw sleeve is slidably mounted on the spaced apart support posts for substantially friction free movement thereover. The longitl1~; nA 1 axes of the spaced apart support posts and bearings are parallel to the longitll~ i nA 1 axis of the ram means and the redraw sleeve holds the can blank 80 that the longitudinal axis thereof is aligned with the longitudinal axis of the ram means. Reciprocating means are provided for providing reciprocal movement of the redraw carriage over the spaced apart support posts. A counter-balancing means, comprising a plurality of springs mounted in a fixed position and applying a force against a portion of the reciprocating means, removes substantially all of the weight on the redraw carriage to virtually eliminate wear of the bushings and posts.

In the apparatus illustrated in Fig. 1, a frame lo has a ram carriage 12 mounted thereon for reciprocating movement over a pair of spaced apart opposed way strips (not shown). The ram carriage 12 has a ram 14 mounted thereon so that during the forward stroke, the ram 14 will pass through the redraw apparatus 16, having a cup feeding ~ 5 ~ 1 336247 means 17, and through the housing 18 containing the can forming and ironing dies 6imilar to those in U.S.
Patent No. 3,735,629. The mech~n~sm for reciprocating the ram carriage 12 includes the motor 20, the pulley wheel 22, the crank shafts 24, the crank arms 26, the crank pins 28, the main connecting rod 30 and cross-head members 32, all of which are conventional.
The redraw apparatus 102 of this invention is illustrated in Figs. 1 - 4 and comprises a redraw carriage 40 having a conventional redraw sleeve 42.
The redraw carriage 40 is provided with a pair of spaced apart longitudinally extending bores 44 and 46 which are located on both sides of bushing 48 mounted in the redraw carriage 40. One end of each bore 44 and 46 is enlarged and bearing means 50 and 52 are fixedly mounted therein. The bearing means 50 and 52 preferably comprise a hardened steel bushing having a cylindrical inner surface 54. The redraw carriage 40 is also provided with a pair of bores 56 in which are mounted rocker pivots 58 similar to those in the Maytag patent. The redraw carriage 40 also is provided with passageways 60. A rocker arm 62 similar to the one in U.S. patent 3696657 has extensions 64 which extend through the passageways 60 and are pivotally mounted on the rocker pivots 58 to provide the force to reciprocate the redraw carriage 40.
A pair of spaced apart support posts 70 and 72 are fixedly mounted on the housing 18 holding the can forming and ironing dies (not shown). Each of the support posts 70 and 72 has a cylindrical outer surface 74 and has a longit~;nAl axis extending parallel to the longitudinal axis of the ram 14. The redraw carriage 40 is slidably mounted on the support posts 70 and 72 by placing the bearing means 50 and 52 over the support posts 70 and 72. Conventional ~ 3362~7 ~fittings 76 are provided for supplying lubrication for the bearing means 50 and 52. This slidable mounting of the redraw carriage, as illustrated in Figs. 1 - 4, is substantially friction-free and minimizes any wear caused by the reciprocating movement of the redraw carriage so that proper alignment of the redraw sleeve with the ram assembly and the housing holding the can forming and ironing dies is maintained.
The redraw carriage 40 is reciprocated by conventional mechanism as illustrated in Figs. 1 - 3.
The rocker arm 62 is attached to a shoe 78 which supports the conventional movement arresting means 80 including the spring 82 and adjustable stop screw 84.
The shoe 78 is attached to the end 86 of the actuating rod 88 and the end 90 of the actuating rod 88 is pivotally connected to the cam follower lever 92 having a cam follower 94 which is urged against a cam 96 rotated by the wheel 22. An air cylinder 98 is mounted on a fixed support 100 with the free end of its piston rod 102 pivotally connected to the actuating rod 88 at approximately the mid-point thereof. The air cylinder 98 exerts a constant force on the actuating rod 88 through the piston rod 102 to maintain the cam follower 94 in contact with the cam 96 to provide the reciprocating movement to the redraw carriage 40.
A counterbalancing means 110, illustrated in Figs. 1 and 5 - 8, is provided for applying a force on the redraw actuating bar 88 so as to substantially eliminate any weight on the redraw carriage 40. The counterbalancing means 110 comprises an angularly shaped member 112 having passageways 114 and 116 so that it may be secured by headed bolts 118 to the housing of the air cylinder 98. A support member 120 having a U-shaped opening 122 is positioned on the support 100 and secured thereto by a set screw 124. A
plurality of holes 126 are formed in the support _ 7 1 336247 ~membèr 120 and extend partially therethrough and have openings in the upper surface 128 thereof. A coiled spring 130 is located in each hole. As illustrated in Fig. 1, the support member 120 is located relative to the member 112 so that the coiled springs 130 are in contact with a generally planar bottom surface 132 on the member 112. Pivot means 134 are provided for pivotally connecting the end of the piston rod 102 to the redraw actuating bar 88. This pivot means 134 is connected to the redraw actuating bar 88 at a generally central location. The coiled springs 130 function to provide a force on the member 112 so as to counterbalance the weight of the redraw actuating bar 88 and its associated structures so that there is substantially no weight placed on the redraw carriage 40. Set screws 136 are threadedly mounted in threaded bores 138 in the support member 120 so that the ends thereof are in contact with the coiled springs 130 so that the amount of force being applied by the coiled springs 130 may be adjusted. This counterbalancing means 110 virtually eliminates any wear of the bushing means 50 and 52 and the support posts 70 and ?2 so that proper alignment of the redraw sleeve with the ram assembly and the housing holding the can forming and ironing dies is maintained.
The redraw carriage 40 and the redraw sleeve 42 are reciprocated over the support posts 70 and 72 to position a can blank (not shown) to be contacted by the ram 14 and be pushed through the can forming and ironing dies in the housing 18 to form a can body.
Ram assembly means 150, to be substituted for the ram assembly means of Fig. 1, are illustrated in Fig. 9 and comprise a fixed support frame means 152 secured to a foundation (not shown). A pair of spaced apart, elongated shafts 154 and 156 are secured at a fixed location on the support frame means 152 by suitable means (not shown). The elongated shafts 154 and i56 have generally cylindrical outer surfaces 158 and 160. Ram carriage means 170 are illustrated in Figs. 10 - 12 and include a generally rectangularly shaped central body portion 172 and two end members 174 and 176 having arcuately shaped end surfaces 178.
Liquid bearing means 180 and 182 are secured to the arcuately shaped end surfaces 178 by suitable means, such as by welding. The liquid bearing means 180 and 182 have a plurality of liquid inlet means 184 and a plurality of liquid outlet means 186 for purposes described below. Also, the top surfaces 188 and 190 of the liquid bearing means 180 and 182 are generally planar and are provided with a plurality of threaded bores 192 for mounting a manifold means thereon as described below. A central recess 194 is formed in the end member 174 and has a plurality of spaced apart threaded bores 196 for mounting the ram means as described below. A central cavity 198 is formed in the end member 176 and is dimensioned to be coupled to the drive means for reciprocating the ram carriage means 170 as described below.
Manifold means 200, illustrated in Figs. 9, 13 and 15, are secured to the top surfaces 188 and 190 by suitable means (not shown) such as threaded bolts in the threaded bores 192. The manifold means 200 has a main body portion 202 having a liquid inlet means 204 and a liquid outlet means 206. A passageway 208 receives liquid from the liquid inlet means 204 and distributes the liquid through branch passageways 210 through the liquid inlet means 184 of the liquid bearing means 180 and 182 to an annular passageways 212. Liquid is removed from the liquid bearing means 180 and 182 through a passageway 214 connected to branch passageways 216 which receive liquid from radially extending passageways 218 in fluid communication with the liquid outlet means 186 in the liquid bearing means 180 and 182 and pass such liquid 9 1 3362~7 ~through liquid outlet means 206 and then to a drain basin, as described below.
The liquid bearing means 182 are illustrated more particularly in Figs. 13 and 14 and comprise a hollow elongated housing means 230 having the generally planar top surface 190 and a generally cylindrical inner surface 232 having a centrally located radially inwardly projecting flange portion 234. Two liquid bearing members 236 each having a generally cylindrical outer surface 238 having substantially the same diameter as the generally cylindrical surface 232 are positioned in mating relationship therewith and in abutting relationship with the flange portion 234. An end closing member 240 having an axially inwardly projection portion 242 is secured to the elongated housing by suitable means (not shown), such as bolts in threaded bores, to restrict the flow of the liquid out of the bearing members 236 so that the liquid will flow through the liquid outlet means 186. Each liquid bearing member 236 has a generally cylindrical inner surface 244 in which are formed a plurality of spaced apart pocket cavities 246 each of which has an arcuate surface 248 which is a portion of a cylindrical surface having an axis offset from the axis of the general cylindrical inner surface 244. A centrally located radially exten~ing passageway 250 is in fluid communication with each pocket cavity 246 and the annular passageway 212. Suitable fittings (not shown) are mounted in each passageway 250 to control the flow of liquid into each pocket cavity 246. Access openings 254 are provided for permitting insertion or adjustment of the fittings and when the bearings are in use, these access openings 254 are sealed with plug means (not shown).
Ram means 260 are illustrated in Fig. 9 and comprise a ram 262 having a generally cylindrical - lo 1 3 3 6 2 4 7 ~uter surface 264 having substantially the same diameter as the inner diameter of the can body to be formed. The ram 262 has an integral flanged portion 266 which is positioned in the central recess 194 and secured therein by suitable means (not shown) such as bolts secured in the threaded bores 196. Guide means 268 are fixedly mounted in support members 270 fixedly secured to the support frame means 152. The guide means 268 comprise liquid bearing means 272 similar to liquid bearing means 180 and 182 except that the housing means thereof contains only one liquid bearing member 236. Manifold means (not shown) will provide liquid to the liquid inlet means 184 and remove liquid from the liquid outlet means 186. The longitudinal axes of the elongated shafts 154 and 156, the liquid bearing means 180, 182 and 272 and the ram means 260 are in parallel relationship with each other. A ball and socket means 274 is used to connect the end member 176 to the main connecting rod 30. It is understood that suitable fittings and sealing members are used where necessary to control the flow of the liquid. In the preferred embodiment, the liquid used is taken from the pool of coolant used conventionally with can body making apparatus.
In the operation of the apparatus illustrated in Figs. 9 - 15, the ram carriage assembly 150 is mounted on the fixed support frame means 152 so that the front end portion 276 of the ram 262 will pass through the redraw apparatus 16 and the housing 18 containing the can forming and ironing dies.
Liquid conducting means 276 are connected to the liquid inlet means 204 and a coolant storage tank 278 to provide coolant from the coolant storage tank 278 as the liquid to each of the liquid bearing means 180 and 182. The coolant is provided at suitable pressures so that the pressure in each of the pocket cavities 246 is between about 150 and 500 psi and 1 3.6~7 -prefe`rably about 200 psi. The coolant comprises about 97 per cent water to which are added solubles. Liquid conducting means 280 are connected to the liquid outlet means 206 and to a drain basin 282 for removing s coolant passing through the liquid bearing means 180 and 182. The connecting rod 30 applies reciprocating forces on the ram carriage means 170 so that the ram 262 moves back and forth through the redraw apparatus 16 and the housing 18 so as to form can bodies at the rate of between about 150 and 300 can bodies per minute. The liquid bearing members 236 permit substantially friction free movement of the ram carriage means over the elongated shafts 154 and 156 and ram 262 through the liquid bearing means 272 so that there is substantially no wear to cause misalignment problems. Also, the liquid bearing members 236 provide pressure equalization means so that the ram carriage means move over the elongated shaft means 154 and 156 in an equilibrium position.
The ram assembly means of this invention weighs less than~that illustrated in U.S. patent 3696657 so that it may be moved using substantially less power. The lighter weight also allows the reciprocation to be reversed more easily so that more cans may be produced each minute. Also, by substantially eliminating wear, downtime and maintenance are substantially reduced.
While an illustrative and presently preferred embodiment of the invention has been described in detail herein, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art.
This invention relates generally to a can body making apparatus and more particularly to an improvement in the ram assembly apparatus for maintaining more accurate alignment of the ram during the reciprocation thereof and in the redraw apparatus for providing and maintaining more accurate alignment of the can blanks with the ram and the tool pack containing the can forming and ironing dies.
A can body making apparatus is disclosed in U.S. Patent No. 3,696,657. The ram carriage and redraw carriage are each mounted on rollers which move over carriage way strips. Each pair of upper and lower rollers are urged toward each other so as to be in firm contact with the carriage way strip located therebetween. Both the ram and redraw carriages are reciprocated at rates sufficient to form about two hundred cans a minute. The constant reciprocal movement of the ram and redraw carriages and the tight engagement of the rollers on the carriage way strips result in wear which causes misalignment of the ram or of the can blanks by the redraw sleeve. It is understood that this misalignment is small, between about o.oos and O.olo of an inch, but such misalignment can result in defective cans.
This invention provides ram assembly means _, ~
~ 336247 ~for a can body making apparatus wherein ram means are mounted on ram carriage means which have a pair of liquid bearing means for mounting the ram carriage means for reciprocal movement over a pair of fixedly 5 mounted, spaced apart, elongated shafts. Also, guide means, such as liquid bearing means, are provided for guiding the reciprocal movement of the ram means therethrough.
This invention also provides a redraw apparatus for a can body making apparatus wherein the redraw carriage is slidably mounted on a pair of spaced apart support posts for reciprocal movement thereover, which support posts are fixedly mounted on the housing holding the can forming and ironing dies.
The invention also provides counterbalancing means for supporting at least a major portion of the weight of the redraw actuating rod, also known as the push rod, to substantially eliminate the weight on the carriage sleeve for more efficient operation.
In the preferred embodiment of the invention, ram assembly means are provided for a can body making apparatus having means for reciprocating a ram carriage means and a ram means along their longitudinal axes so that the ram means push a can blank through can forming and ironing dies to form a can body. The ram assembly means include a pair of spaced apart, elongated shafts having generally cylindrical outer surfaces and which are fixedly mounted on a fixed frame means. The ram means are mounted on a ram carriage means that have a pair of spaced apart liquid bearing means each having a cylindrical inner surface for reciprocal movement over the elongated shafts. The liquid bearing means has a plurality of arcuately shaped pocket means, each of which is supplied with a liquid, preferably from the coolant supply of the can body making apparatus, at suitable pressures. Each liquid bearing means also _ _ 3 _ ~as iiquid return means for removing the liquid supplied to the pocket means. Guide means, preferably comprising liquid bearing means, are fixedly mounted on the frame means and are located so that the ram means are supported for reciprocal movement therethrough. A redraw carriage including a redraw sleeve is located between the ram assembly means and the can forming and ironing dies and functions to hold a can blank in the proper position against the can forming and ironing dies 80 that the ram means will push the can blank through the can forming and ironing dies to form a can body. The redraw apparatus includes a redraw carriage that is provided with a pair of spaced apart bearings having generally cylindrical inner surfaces. A pair of spaced apart support posts are fixedly mounted on the housing holding the can forming and ironing dies and have generally cylindrical outer surfaces. The redraw sleeve is slidably mounted on the spaced apart support posts for substantially friction free movement thereover. The longitl1~; nA 1 axes of the spaced apart support posts and bearings are parallel to the longitll~ i nA 1 axis of the ram means and the redraw sleeve holds the can blank 80 that the longitudinal axis thereof is aligned with the longitudinal axis of the ram means. Reciprocating means are provided for providing reciprocal movement of the redraw carriage over the spaced apart support posts. A counter-balancing means, comprising a plurality of springs mounted in a fixed position and applying a force against a portion of the reciprocating means, removes substantially all of the weight on the redraw carriage to virtually eliminate wear of the bushings and posts.

In the apparatus illustrated in Fig. 1, a frame lo has a ram carriage 12 mounted thereon for reciprocating movement over a pair of spaced apart opposed way strips (not shown). The ram carriage 12 has a ram 14 mounted thereon so that during the forward stroke, the ram 14 will pass through the redraw apparatus 16, having a cup feeding ~ 5 ~ 1 336247 means 17, and through the housing 18 containing the can forming and ironing dies 6imilar to those in U.S.
Patent No. 3,735,629. The mech~n~sm for reciprocating the ram carriage 12 includes the motor 20, the pulley wheel 22, the crank shafts 24, the crank arms 26, the crank pins 28, the main connecting rod 30 and cross-head members 32, all of which are conventional.
The redraw apparatus 102 of this invention is illustrated in Figs. 1 - 4 and comprises a redraw carriage 40 having a conventional redraw sleeve 42.
The redraw carriage 40 is provided with a pair of spaced apart longitudinally extending bores 44 and 46 which are located on both sides of bushing 48 mounted in the redraw carriage 40. One end of each bore 44 and 46 is enlarged and bearing means 50 and 52 are fixedly mounted therein. The bearing means 50 and 52 preferably comprise a hardened steel bushing having a cylindrical inner surface 54. The redraw carriage 40 is also provided with a pair of bores 56 in which are mounted rocker pivots 58 similar to those in the Maytag patent. The redraw carriage 40 also is provided with passageways 60. A rocker arm 62 similar to the one in U.S. patent 3696657 has extensions 64 which extend through the passageways 60 and are pivotally mounted on the rocker pivots 58 to provide the force to reciprocate the redraw carriage 40.
A pair of spaced apart support posts 70 and 72 are fixedly mounted on the housing 18 holding the can forming and ironing dies (not shown). Each of the support posts 70 and 72 has a cylindrical outer surface 74 and has a longit~;nAl axis extending parallel to the longitudinal axis of the ram 14. The redraw carriage 40 is slidably mounted on the support posts 70 and 72 by placing the bearing means 50 and 52 over the support posts 70 and 72. Conventional ~ 3362~7 ~fittings 76 are provided for supplying lubrication for the bearing means 50 and 52. This slidable mounting of the redraw carriage, as illustrated in Figs. 1 - 4, is substantially friction-free and minimizes any wear caused by the reciprocating movement of the redraw carriage so that proper alignment of the redraw sleeve with the ram assembly and the housing holding the can forming and ironing dies is maintained.
The redraw carriage 40 is reciprocated by conventional mechanism as illustrated in Figs. 1 - 3.
The rocker arm 62 is attached to a shoe 78 which supports the conventional movement arresting means 80 including the spring 82 and adjustable stop screw 84.
The shoe 78 is attached to the end 86 of the actuating rod 88 and the end 90 of the actuating rod 88 is pivotally connected to the cam follower lever 92 having a cam follower 94 which is urged against a cam 96 rotated by the wheel 22. An air cylinder 98 is mounted on a fixed support 100 with the free end of its piston rod 102 pivotally connected to the actuating rod 88 at approximately the mid-point thereof. The air cylinder 98 exerts a constant force on the actuating rod 88 through the piston rod 102 to maintain the cam follower 94 in contact with the cam 96 to provide the reciprocating movement to the redraw carriage 40.
A counterbalancing means 110, illustrated in Figs. 1 and 5 - 8, is provided for applying a force on the redraw actuating bar 88 so as to substantially eliminate any weight on the redraw carriage 40. The counterbalancing means 110 comprises an angularly shaped member 112 having passageways 114 and 116 so that it may be secured by headed bolts 118 to the housing of the air cylinder 98. A support member 120 having a U-shaped opening 122 is positioned on the support 100 and secured thereto by a set screw 124. A
plurality of holes 126 are formed in the support _ 7 1 336247 ~membèr 120 and extend partially therethrough and have openings in the upper surface 128 thereof. A coiled spring 130 is located in each hole. As illustrated in Fig. 1, the support member 120 is located relative to the member 112 so that the coiled springs 130 are in contact with a generally planar bottom surface 132 on the member 112. Pivot means 134 are provided for pivotally connecting the end of the piston rod 102 to the redraw actuating bar 88. This pivot means 134 is connected to the redraw actuating bar 88 at a generally central location. The coiled springs 130 function to provide a force on the member 112 so as to counterbalance the weight of the redraw actuating bar 88 and its associated structures so that there is substantially no weight placed on the redraw carriage 40. Set screws 136 are threadedly mounted in threaded bores 138 in the support member 120 so that the ends thereof are in contact with the coiled springs 130 so that the amount of force being applied by the coiled springs 130 may be adjusted. This counterbalancing means 110 virtually eliminates any wear of the bushing means 50 and 52 and the support posts 70 and ?2 so that proper alignment of the redraw sleeve with the ram assembly and the housing holding the can forming and ironing dies is maintained.
The redraw carriage 40 and the redraw sleeve 42 are reciprocated over the support posts 70 and 72 to position a can blank (not shown) to be contacted by the ram 14 and be pushed through the can forming and ironing dies in the housing 18 to form a can body.
Ram assembly means 150, to be substituted for the ram assembly means of Fig. 1, are illustrated in Fig. 9 and comprise a fixed support frame means 152 secured to a foundation (not shown). A pair of spaced apart, elongated shafts 154 and 156 are secured at a fixed location on the support frame means 152 by suitable means (not shown). The elongated shafts 154 and i56 have generally cylindrical outer surfaces 158 and 160. Ram carriage means 170 are illustrated in Figs. 10 - 12 and include a generally rectangularly shaped central body portion 172 and two end members 174 and 176 having arcuately shaped end surfaces 178.
Liquid bearing means 180 and 182 are secured to the arcuately shaped end surfaces 178 by suitable means, such as by welding. The liquid bearing means 180 and 182 have a plurality of liquid inlet means 184 and a plurality of liquid outlet means 186 for purposes described below. Also, the top surfaces 188 and 190 of the liquid bearing means 180 and 182 are generally planar and are provided with a plurality of threaded bores 192 for mounting a manifold means thereon as described below. A central recess 194 is formed in the end member 174 and has a plurality of spaced apart threaded bores 196 for mounting the ram means as described below. A central cavity 198 is formed in the end member 176 and is dimensioned to be coupled to the drive means for reciprocating the ram carriage means 170 as described below.
Manifold means 200, illustrated in Figs. 9, 13 and 15, are secured to the top surfaces 188 and 190 by suitable means (not shown) such as threaded bolts in the threaded bores 192. The manifold means 200 has a main body portion 202 having a liquid inlet means 204 and a liquid outlet means 206. A passageway 208 receives liquid from the liquid inlet means 204 and distributes the liquid through branch passageways 210 through the liquid inlet means 184 of the liquid bearing means 180 and 182 to an annular passageways 212. Liquid is removed from the liquid bearing means 180 and 182 through a passageway 214 connected to branch passageways 216 which receive liquid from radially extending passageways 218 in fluid communication with the liquid outlet means 186 in the liquid bearing means 180 and 182 and pass such liquid 9 1 3362~7 ~through liquid outlet means 206 and then to a drain basin, as described below.
The liquid bearing means 182 are illustrated more particularly in Figs. 13 and 14 and comprise a hollow elongated housing means 230 having the generally planar top surface 190 and a generally cylindrical inner surface 232 having a centrally located radially inwardly projecting flange portion 234. Two liquid bearing members 236 each having a generally cylindrical outer surface 238 having substantially the same diameter as the generally cylindrical surface 232 are positioned in mating relationship therewith and in abutting relationship with the flange portion 234. An end closing member 240 having an axially inwardly projection portion 242 is secured to the elongated housing by suitable means (not shown), such as bolts in threaded bores, to restrict the flow of the liquid out of the bearing members 236 so that the liquid will flow through the liquid outlet means 186. Each liquid bearing member 236 has a generally cylindrical inner surface 244 in which are formed a plurality of spaced apart pocket cavities 246 each of which has an arcuate surface 248 which is a portion of a cylindrical surface having an axis offset from the axis of the general cylindrical inner surface 244. A centrally located radially exten~ing passageway 250 is in fluid communication with each pocket cavity 246 and the annular passageway 212. Suitable fittings (not shown) are mounted in each passageway 250 to control the flow of liquid into each pocket cavity 246. Access openings 254 are provided for permitting insertion or adjustment of the fittings and when the bearings are in use, these access openings 254 are sealed with plug means (not shown).
Ram means 260 are illustrated in Fig. 9 and comprise a ram 262 having a generally cylindrical - lo 1 3 3 6 2 4 7 ~uter surface 264 having substantially the same diameter as the inner diameter of the can body to be formed. The ram 262 has an integral flanged portion 266 which is positioned in the central recess 194 and secured therein by suitable means (not shown) such as bolts secured in the threaded bores 196. Guide means 268 are fixedly mounted in support members 270 fixedly secured to the support frame means 152. The guide means 268 comprise liquid bearing means 272 similar to liquid bearing means 180 and 182 except that the housing means thereof contains only one liquid bearing member 236. Manifold means (not shown) will provide liquid to the liquid inlet means 184 and remove liquid from the liquid outlet means 186. The longitudinal axes of the elongated shafts 154 and 156, the liquid bearing means 180, 182 and 272 and the ram means 260 are in parallel relationship with each other. A ball and socket means 274 is used to connect the end member 176 to the main connecting rod 30. It is understood that suitable fittings and sealing members are used where necessary to control the flow of the liquid. In the preferred embodiment, the liquid used is taken from the pool of coolant used conventionally with can body making apparatus.
In the operation of the apparatus illustrated in Figs. 9 - 15, the ram carriage assembly 150 is mounted on the fixed support frame means 152 so that the front end portion 276 of the ram 262 will pass through the redraw apparatus 16 and the housing 18 containing the can forming and ironing dies.
Liquid conducting means 276 are connected to the liquid inlet means 204 and a coolant storage tank 278 to provide coolant from the coolant storage tank 278 as the liquid to each of the liquid bearing means 180 and 182. The coolant is provided at suitable pressures so that the pressure in each of the pocket cavities 246 is between about 150 and 500 psi and 1 3.6~7 -prefe`rably about 200 psi. The coolant comprises about 97 per cent water to which are added solubles. Liquid conducting means 280 are connected to the liquid outlet means 206 and to a drain basin 282 for removing s coolant passing through the liquid bearing means 180 and 182. The connecting rod 30 applies reciprocating forces on the ram carriage means 170 so that the ram 262 moves back and forth through the redraw apparatus 16 and the housing 18 so as to form can bodies at the rate of between about 150 and 300 can bodies per minute. The liquid bearing members 236 permit substantially friction free movement of the ram carriage means over the elongated shafts 154 and 156 and ram 262 through the liquid bearing means 272 so that there is substantially no wear to cause misalignment problems. Also, the liquid bearing members 236 provide pressure equalization means so that the ram carriage means move over the elongated shaft means 154 and 156 in an equilibrium position.
The ram assembly means of this invention weighs less than~that illustrated in U.S. patent 3696657 so that it may be moved using substantially less power. The lighter weight also allows the reciprocation to be reversed more easily so that more cans may be produced each minute. Also, by substantially eliminating wear, downtime and maintenance are substantially reduced.
While an illustrative and presently preferred embodiment of the invention has been described in detail herein, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art.
