[0028] Embodiment one
[0029] The embodiment is the first embodiment of the production line compatible with the multi-process single punch press and the continuous die punch press, as shown in Figures 1 to 5As shown, the production line includes a feeding robot 1, a transfer robot 3, a discharging robot 4, a first ground rail 5 arranged on the ground, and at least two groups of punching machines 2. The feeding robot 1, the punching machines 2, and the discharging robot 4 are sequentially arranged along the transverse direction, and the transfer robot 3 is located between two adjacent groups of punching machines 2. Each punching machine 2 includes an upper die 21 and a lower die 22 for placing a die 9, and the lower die 22 is slidably connected to the first ground rail 5. The first ground rail 5 extends from below the upper die 21 to a die changing area on the longitudinal side of the punching machine 2. The production line further includes a steel coil feeding machine 6, a flattening machine 7, and a second ground rail 8 arranged on the ground. The punching machines 2, the flattening machine 7, and the steel coil feeding machine 6 are sequentially arranged along the longitudinal direction. The second ground rail 8 is arranged along the transverse direction on the longitudinal side of the punching machine 2, and the flattening machine 7 is slidably connected to the second ground rail 8.
[0030] The above-mentioned production line compatible with multi-process single-punching and continuous die punching is used for multi-process single-punching production. The part blank is fed to the adjacent punching machine 2 by the feeding robot 1 for punching, then transferred to the punching machine 2 of the next process by the transfer robot 3 for punching, and finally discharged by the discharging robot 4. When used for continuous die punching production, the flattening machine 7 is slid out of the die changing area to avoid the die changing area of the punching machine 2 corresponding to the steel coil feeding machine 6. The lower die 22 of the punching machine 2 and the die 9 thereon are slid out to the die changing area, the die 9 is lifted and changed by a crane, then the lower die 22 and the changed die 9 are slid into the lower side of the upper die 21 to avoid the die changing area of the punching machine 2 corresponding to the steel coil feeding machine 6. The flattening machine 7 is slid into the die changing area, the steel coil is conveyed to the flattening machine 7 by the steel coil feeding machine 6, and the flattened steel coil is sent to the punching machine 2 for continuous die punching production. In this embodiment, the first ground rail 5 and the lower die 22 are slidably connected, and the second ground rail 8 and the flattening machine 7 are slidably connected, so that the multi-process single-punching production mode and the continuous die punching production mode can be switched. The number of punching machines 2 can be reduced, the equipment cost can be saved, and the floor area of the production line can be reduced.
[0031] As shown in Figures 1 to 4 The steel coil feeding machine 6 and the flattening machine 7 are each provided with one machine, and one group of punching machines 2 is arranged corresponding to the steel coil feeding machine 6 along the longitudinal direction. The flattening machine 7 slides into or out of the die changing area of the corresponding punching machine 2 along the second ground rail 8. When multi-process single-punching production is performed, all the punching machines 2 are put into use. When continuous die punching production is performed, the punching machines 2 corresponding to the steel coil feeding machine 6 can be used for continuous die punching production after die changing. This embodiment is compatible with multi-process single-punching production and continuous die punching production, and one continuous die punching production machine 2 is saved, the idle rate and cost of the equipment are reduced, and the total floor area of the production line is reduced.
[0032] The second ground rail 8 extends from the die changing area of the punching machine 2 corresponding to the steel coil feeding machine 6 to the longitudinal side of the feeding robot 1, the transfer robot 3, or the discharging robot 4 adjacent to the corresponding punching machine 2, as shown in Figures 1 to 4When the production part type is replaced or the stamping production mode is replaced, the punch 2 needs to replace the corresponding die 9, the flattening machine 7 slides out from the die changing area to the longitudinal side of the feeding robot 1, the transfer robot 3 or the discharging robot 4 adjacent to the punch 2, the lower die 22 and the die 9 thereon slide out to the die changing area for die changing, and then slide under the upper die 21. In the continuous die stamping production mode, the flattening machine 7 slides into the die changing area of the corresponding punch 2. In the embodiment, the layout length of the second ground rail 8 can meet the die changing needs and reduce the floor area.
[0033] As shown in Figures 1 to 4 each group of punches 2 corresponds to two first ground rails 5, and the bottom transverse ends of the lower die 22 are respectively connected with the corresponding two first ground rails 5. In the implementation, the two first ground rails 5 can guide the lower die 22 together, which can improve the stability of the sliding of the lower die 22.
[0034] As shown in Figures 1 to 4 two second ground rails 8 are arranged, and the longitudinal ends of the bottom of the flattening machine 7 are respectively connected with the two second ground rails 8. In the implementation, the two second ground rails 8 can guide the flattening machine 7 together, which can improve the stability of the sliding of the flattening machine 7.
[0035] The bottom of the flattening machine 7 is provided with a pulley which slides in the second ground rail 8. In the implementation, the pulley can facilitate the movement of the flattening machine 7, and the directional sliding can be realized by the cooperation of the pulley and the second ground rail 8 to avoid the die changing area.
[0036] Embodiment two
[0037] The second embodiment of the production line compatible with multiple processes and single stamping and continuous die stamping is similar to the first embodiment, and the difference is that the number of the steel coil feeding machine 6 and the number of the flattening machine 7 are consistent with the number of the punch 2, and the steel coil feeding machine 6 and the punch 2 are arranged one by one, and each group of flattening machines 7 slides into or out of the die changing area of the corresponding punch 2 along the second ground rail 8. In the implementation, each punch 2 corresponds to a steel coil feeding machine 6 and a flattening machine 7, and each punch 2 can perform stamping operation when the continuous die stamping production is replaced, which improves the production efficiency. In addition, different types of parts can be continuously stamped by replacing different dies 9, which can reduce the idle rate of equipment and improve the utilization rate of equipment under the condition that the production of parts is not high. Further, the number of punches 2 is reduced, and the cost of equipment is reduced.
[0038] The second ground rail 8 extends from the longitudinal side of the upper feeding robot 1 to the longitudinal side of the punch 2 adjacent to the lower discharging robot 4. In practice, each leveling machine 7 shares the second ground rail 8, and when mold changing is needed, the leveling machine 7 slides out of the mold changing area of the corresponding punch 2 to the longitudinal side of the upper feeding robot 1 or the longitudinal side of the transfer robot 3 in front of the punch 2, which can meet the simultaneous mold changing of each punch 2.
[0039] The punch 2 is provided with four groups, the steel coil feeding machine 6 and the leveling machine 7 are respectively provided with four machines, and the four steel coil feeding machines 6 and the four leveling machines 7 are respectively arranged corresponding to the four groups of punches 2. The four leveling machines 7 respectively slide into or out of the mold changing area of the corresponding punch 2 along the second ground rail 8. Generally, the multi-process single stamping production includes four processes, and during the multi-process single stamping production, the four punches 2 are respectively used for the first process, the second process, the third process and the fourth process of part production. The part blank is fed by the upper feeding robot 1 to the first punch 2 to complete the first process, and is transferred to the next process for production by the transfer robot 3, and finally is discharged by the lower discharging robot 4; when switching to continuous die stamping production, the leveling machines 7 respectively slide out of the mold changing areas of the four punches 2 to the longitudinal sides of the upper feeding robot 1 and the transfer robot 3, and the lower dies 22 of the punches 2 of the four processes can respectively slide out to the corresponding mold changing areas along the corresponding first ground rails 5 for mold 9 replacement. The lower die 22 after mold changing slides out from the mold changing area to the lower side of the upper die 21, and the four leveling machines 7 respectively slide into the corresponding mold changing areas to cooperate with the steel coil feeding machine 6 and the punch 2 for continuous die stamping production. It should be noted that when the number of processes of multi-process single stamping production increases, the number of punches 2 can be increased accordingly to meet the needs of multi-process production.
[0040] Embodiment three
[0041] This embodiment is the third embodiment of the production line compatible with multi-process single stamping and continuous die stamping. This embodiment is similar to embodiment two, except that the second ground rail 8 extends from the longitudinal side of the punch 2 adjacent to the upper feeding robot 1 to the longitudinal side of the lower discharging robot 4. In practice, each leveling machine 7 shares the second ground rail 8, and when mold changing is needed, the leveling machine 7 slides out of the mold changing area of the corresponding punch 2 to the longitudinal side of the transfer robot 3 or the longitudinal side of the lower discharging robot 4 behind the punch 2, which can meet the simultaneous mold changing of each punch 2.
