Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, in particular to sheet metal stamping equipment. Background Art

[0002] Stamping equipment relies on presses and dies to apply external force to plates, strips, tubes and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the desired shape and size.

[0003] Existing sheet metal stamping equipment requires the use of an upper die and a lower die when stamping, and the shapes of the upper die and the lower die are fixed. Therefore, the same set of upper and lower dies can only process sheet metal parts of the same shape. When sheet metal parts of other shapes need to be processed, a new set of upper and lower dies needs to be replaced. In the production process, sometimes it is necessary to alternately process two sheet metal parts of different shapes. At this time, it is necessary to frequently switch between the two stamping forms. The existing stamping equipment is complicated to install and disassemble the upper and lower dies.

[0013] Beneficial effects of the present invention:

[0014] 1: By setting up the upper and lower die flipping mechanism, it is beneficial to expand the use range of stamping equipment and improve processing efficiency. Usually, the upper die and the lower die are used in conjunction with each other and have a fixed shape, so only sheet metal parts of the same shape can be processed. When a sheet metal part of another shape needs to be processed, it is only necessary to start the upper and lower die flipping mechanism, so that the upper die and the lower die are flipped 180 degrees, the top and bottom of the upper die are swapped, and the top and bottom of the lower die are swapped. The flipped upper and lower dies are combined to process a sheet metal part of another shape, so that this stamping equipment can process two different shapes of sheet metal parts according to needs without disassembling and replacing the upper and lower dies, so that the equipment has two different stamping forms, and can quickly switch back and forth between two different stamping forms, which is safe and convenient.

[0015] 2: By setting the upper and lower dies that are easy to disassemble, it is beneficial to further expand the scope of use of the stamping equipment and reduce the labor intensity of workers. The upper and lower die flipping mechanism can be used to process two different shapes of sheet metal parts. When sheet metal parts of other shapes need to be processed, a new set of upper and lower dies need to be replaced. When the existing stamping equipment removes the upper and lower dies separately, and when removing the upper die, there is a safety hazard because the upper die is connected to the hydraulic column. When using this equipment to replace the upper and lower dies, the upper die is not connected to the hydraulic column. First, the upper die is lowered so that the upper die and the lower die are combined together, and then the upper die is removed from between the first slide and the second slide, and the lower die is removed from between the first bracket and the second bracket. Finally, the upper die and the lower die are moved away together, which can not only improve the efficiency of the installation and disassembly of the upper and lower dies, but also improve the safety performance of the equipment.

[0016] 3: The electric telescopic rod, pressurized gas cylinder, pressurized sliding rod, supporting sliding rod and supporting gas cylinder form a lifting mechanism, which is conducive to improving the stability of the upper mold when it rises and falls, and this mechanism enables the upper mold to rise and fall independently without relying on the hydraulic column, which is helpful for replacing and repairing the upper mold.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] like Figure 1-Figure 7As shown, a sheet metal stamping equipment described in the present invention includes a base 1, a hydraulic column 3, an upper and lower die turning mechanism 7, a pillar 8, a first slide 9, and a second slide 10. The top of the base 1 is fixedly connected to a support 2, the top of the support 2 is fixedly connected to a hydraulic column 3, and the output end of the hydraulic column 3 is opposite to the top of the base 1, and the output end of the hydraulic column 3 is fixedly connected to a die 4. The top of the base 1 is provided with a turning notch 19 below the die 4, and the top of the base 1 is respectively provided with a first bracket 5 and a second bracket 6 at the edges of both sides near the turning notch 19, and the first bracket 5 is slidably connected to the top of the base 1, and the second bracket 6 is fixedly connected to the top of the base 1, and pillars 8 are fixedly installed between the base 1 and the support 2 near the first bracket 5 and the second bracket 6, the second slide 10 is slidably connected to the pillar 8 near the first bracket 5, and the first slide 9 is slidably connected to the pillar 8 near the second bracket 6, and an upper and lower die turning mechanism 7 is installed between the first bracket 5 and the second slide 10.

[0028] The upper and lower mold flipping mechanism 7 includes a double-axis motor 71, a lower mold 73, an upper mold 76, and a driven key shaft 77. The top of the base 1 is fixedly connected with the double-axis motor 71 near the second bracket 6, and the end of the double-axis motor 71 near the second bracket 6 is provided with a first output shaft 72. The lower mold 73 is detachably installed between the first bracket 5 and the second bracket 6, and the lower mold 73 is transmission-connected to the first output shaft 72. The second output shaft 74 is provided at the end of the double-axis motor 71 away from the second bracket 6. The second slide 10 is detachably and rotatably installed with a driven key shaft 77, and the first slide 9 is rotatably connected with a transmission key shaft 75. The upper mold 76 is detachably and transmission-connected between the transmission key shaft 75 and the driven key shaft 77, and the end of the transmission key shaft 75 away from the first slide 9 is transmission-connected to the second output shaft 74.

[0029] Specifically, the second output shaft 74 extends into the interior of the support 2 and is fixedly connected to the first transmission wheel 741, and the end of the transmission key shaft 75 away from the first slide 9 is fixedly connected to the second gear 746. One side of the support 2 is rotatably connected to the transmission shaft 745 near the top of the transmission key shaft 75, and one end of the transmission shaft 745 is fixedly connected to the first gear 744, and the first gear 744 is meshed with the second gear 746. The other end of the transmission shaft 745 is fixedly connected to the second transmission wheel 743, and the first transmission wheel 741 and the second transmission wheel 743 are connected through a belt 742. The double-axis motor 71 is started, and the first output shaft 72 and the second output shaft 74 at both ends of the double-axis motor 71 start to rotate. The first output shaft 72 drives the lower mold 73 to flip through the slide sleeve 731, and the second output shaft 74 drives the first transmission wheel 741 to rotate. The first transmission wheel 741 drives the second transmission wheel 743 to rotate through the belt 742, and the second transmission wheel 743 drives the first gear 744 to rotate through the transmission shaft 745. The first gear 744 drives the transmission key shaft 75 to rotate through the second gear 746, and the transmission key shaft 75 drives the upper mold 76 to flip. The flip angles of the upper mold 76 and the lower mold 73 are consistent, and the double-axis motor 71 stops running after the lower mold 73 and the upper mold 76 flip 180 degrees. At this time, the top and bottom of the lower die 73 are swapped, and the top and bottom of the upper die 76 are swapped. The shapes of the grooves in the top and bottom of the lower die 73 are different, and the shapes of the protrusions at the top and bottom of the upper die 76 are also different. Therefore, after flipping one hundred and eighty degrees, the upper die 76 and the lower die 73 are combined to process sheet metal parts of another shape, thereby increasing the scope of use of this sheet metal stamping equipment and improving processing efficiency.

[0030] Specifically, both sides of the lower mold 73 are fixedly connected with a slide sleeve 731, and the length of the slide sleeve 731 on the side close to the second bracket 6 is greater than the length of the slide sleeve 731 on the other side, the slide sleeve 731 close to the second bracket 6 passes through the second bracket 6 and is inserted into the first output shaft 72, and the side of the first bracket 5 close to the lower mold 73 is rotatably connected with a short shaft 732, and the slide sleeve 731 close to the first bracket 5 is inserted into the short shaft 732, and shaft holes 761 are provided on both sides of the upper mold 76, and the end of the transmission key shaft 75 away from the second gear 746 is inserted in the shaft hole 761 adjacent to it, and the end of the driven key shaft 77 close to the upper mold 76 is inserted in the shaft hole 761 adjacent to it.

[0031] Specifically, the end of the driven key shaft 77 away from the upper mold 76 is sleeved with a fixed seat 772, and a bearing 774 is arranged inside the fixed seat 772. The driven key shaft 77 is rotatably connected to the fixed seat 772 through the bearing 774. A bolt 773 is arranged at one end of the fixed seat 772 close to the second slide seat 10. A spline sleeve 771 is arranged inside the second slide seat 10. The driven key shaft 77 passes through the spline sleeve 771, and the driven key shaft 77 is rotatably connected to the second slide seat 10 through the spline sleeve 771. The driven key shaft 77 can be pulled out from the spline sleeve 771. The above structure is provided to facilitate the disassembly and installation of the upper die 76 and the lower die 73. The specific disassembly process is: firstly, the upper die 76 is lowered to the top of the lower die 73 and combined with the lower die 73, and then the bolt 773 is loosened with a wrench to release the fixed connection between the fixing seat 772 and the second slide seat 10, and the driven key shaft 77 is pulled to separate the driven key shaft 77 from the upper die 76, and then the electric push column 18 is started, and the electric push column 18 pushes the lower die 73, the upper die 76 and the first bracket 5 together. Move in the direction away from the second bracket 6. During the movement, the slide sleeve 731 of the lower mold 73 close to the first output shaft 72 is separated from the first output shaft 72 and pulled out from the second bracket 6, and the upper mold 76 is separated from the transmission key shaft 75. After moving to the farthest position, manually push the first bracket 5 to separate the short shaft 732 from the lower mold 73. At this time, the upper mold 76 and the lower mold 73 have been disassembled, and the old upper mold 76 and the lower mold 73 are clamped by a robot, and then replaced with new upper mold 76 and the lower mold 73.

[0032] The outer walls of the first output shaft 72 and the short shaft 732 are provided with convex strips, and the interior of the slide sleeve 731 is provided with slide grooves adapted to the convex strips, so when the slide sleeves 731 at both ends of the lower die 73 are respectively plugged into the short shaft 732 and the first output shaft 72, the lower die 73 can be driven to flip, and it is convenient to remove the lower die 73 from the short shaft 732 and the first output shaft 72. Similarly, the outer walls of the transmission key shaft 75 and the driven key shaft 77 are provided with splines, and the shaft holes 761 at both ends of the upper die 76 are provided with keyways adapted to the splines, so when the transmission key shaft 75 and the driven key shaft 77 are respectively plugged into the shaft holes 761 at both ends of the upper die 76, the upper die 76 can be driven to flip, and it is convenient to remove the upper die 76 from the transmission key shaft 75 and the driven key shaft 77.

[0033] Specifically, the interior of the base 1 is fixedly connected to a limited electric lifting column 11 below the flip notch 19, the top of the limited electric lifting column 11 is fixedly connected to a limited support seat 12, the top of the limited support seat 12 is in contact with the bottom of the lower mold 73, and the middle of the top of the limited support seat 12 is fixedly connected to a first gas cylinder 13, the top of the first gas cylinder 13 is slidably connected to a first slide bar 14, a return spring 15 is fixedly connected between the top of the first slide bar 14 and the first gas cylinder 13, the top of the limited support seat 12 is fixedly connected to a second gas cylinder 16 at both sides close to the first gas cylinder 13, and the end of the second gas cylinder 16 away from the first gas cylinder 13 is slidably connected to a second slide bar 17. Before operating the upper and lower mold flipping mechanism 7, it is necessary to start the limited electric lifting column 11 to shorten it, and the limited electric lifting column 11 drives the limited support seat 12 to descend, and the lower mold 73 can be flipped after the limited support seat 12 is separated from the lower mold 73. After the lower die 73 is turned over, the position-limiting electric lifting column 11 is started to extend it, and the position-limiting electric lifting column 11 drives the position-limiting support seat 12 to rise, so that it abuts against the bottom end of the lower die 76, thereby completing the position-limiting of the lower die 76, so that the lower die 76 is kept in a horizontal position and cannot rotate. And when the position-limiting support seat 12 rises, the first slide bar 14 descends to push the air in the first air cylinder 13 into the second air cylinder 16, and the air pressure inside the second air cylinder 16 increases so that the second slide bar 17 abuts against the side wall at the bottom of the lower die 76, preventing the position of the lower die 76 from shifting during the stamping process.

[0034] Specifically, an electric push column 18 is fixedly connected to the top of the base 1 near the dual-axis motor 71 , and the output end of the electric push column 18 is opposite to the lower mold 73 .

[0035] Specifically, one side of the support 2 is fixedly connected to an electric lifting rod 20, the top of the base 1 is fixedly connected to a pressurized gas cylinder 22 near the bottom of the electric lifting rod 20, the top of the pressurized gas cylinder 22 is slidably connected to a pressurized slide bar 21, and the top of the pressurized slide bar 21 is fixedly connected to the output end of the electric lifting rod 20, the top of the base 1 is fixedly connected to a support gas cylinder 23 near the bottom of the second slide seat 10, the top of the support gas cylinder 23 is slidably connected to a support slide bar 24, and the top of the support slide bar 24 is fixedly connected to the bottom end of the second slide seat 10, and the pressurized gas cylinder 22 is connected to the support gas cylinder 23. The above structure constitutes a lifting mechanism, which is required when the upper mold 76 descends and ascends. The specific working process of this mechanism is as follows: when stamping, when the die 4 descends to the top of the upper mold 76 and combines with the upper mold 76, the electric lifting rod 20 starts to shorten its output end, and the electric lifting rod 20 pulls the pressurizing slide bar 21 to make it rise. The pressurizing slide bar 21 draws the air inside the support gas cylinder 23 into the pressurizing gas cylinder 22, and the air pressure inside the support gas cylinder 23 gradually decreases, so the supporting force of the support slide bar 24 on the second slide seat 10 gradually decreases, and the upper mold 76, the first slide seat 9 and the second slide seat 10 slowly descend due to the action of gravity, and finally the upper mold 76 descends to the top of the lower mold 73 and combines with the lower mold 73. After the stamping is completed, the electric lifting rod 20 starts to extend its output end, and the electric lifting rod 20 pushes the air inside the pressurized gas cylinder 22 into the supporting gas cylinder 23 through the pressurized slide bar 21. The air pressure inside the supporting gas cylinder 23 increases, causing the supporting slide bar 24 to rise, and the supporting slide bar 24 pushes the first slide seat 9, the second slide seat 10 and the upper mold 76 to rise. Finally, the upper mold 76 is reset, and the first gear 744 is engaged with the second gear 746. When installing and disassembling the upper mold 76, this mechanism is also needed to make the upper mold 76 rise and fall. This mechanism is conducive to improving the stability of the upper mold 76 when it rises and falls, and this mechanism allows the upper mold 76 to rise and fall independently without relying on the hydraulic column, which is helpful for replacing and repairing the upper mold 76.

[0036] Working principle: When using this sheet metal stamping equipment to process sheet metal parts, first align the metal sheet and place it on the top of the lower die 73, then start the hydraulic column 3, the output end of the hydraulic column 3 drives the die 4 to descend, the bottom of the die 4 is provided with a cavity, then the die 4 is combined with the top of the upper die 76 and drives the upper die 76 to descend, the upper die 76 is finally combined with the lower die 73, and the metal sheet on the top of the lower die 73 is stamped. Since the shape of the convex block at the bottom of the upper die 76 and the groove at the top of the lower die 73 are fixed, the shape of the stamped sheet metal part is also fixed. When a sheet metal part of another shape needs to be processed, the upper and lower die flipping mechanism 7 is started.

[0037] The working process of the upper and lower mold flipping mechanism 7 is as follows: the double-axis motor 71 is started, the first output shaft 72 and the second output shaft 74 at both ends of the double-axis motor 71 start to rotate, the first output shaft 72 drives the lower mold 73 to flip through the slide sleeve 731, the second output shaft 74 drives the first transmission wheel 741 to rotate, the first transmission wheel 741 drives the second transmission wheel 743 to rotate through the belt 742, the second transmission wheel 743 drives the first gear 744 to rotate through the transmission shaft 745, the first gear 744 drives the transmission key shaft 75 to rotate through the second gear 746, and the transmission key shaft 75 drives the upper mold 76 to flip. The flip angles of the upper mold 76 and the lower mold 73 are consistent, and the double-axis motor 71 stops running after the lower mold 73 and the upper mold 76 flip 180 degrees. At this time, the top and bottom of the lower die 73 are swapped, and the top and bottom of the upper die 76 are swapped. The shapes of the grooves in the top and bottom of the lower die 73 are different, and the shapes of the protrusions at the top and bottom of the upper die 76 are also different. Therefore, after flipping one hundred and eighty degrees, the upper die 76 and the lower die 73 are combined to process sheet metal parts of another shape, thereby increasing the scope of use of this sheet metal stamping equipment and improving processing efficiency.

[0038] By using the upper and lower mold flipping mechanism 7, two sheet metal parts of different shapes can be processed using the stamping equipment without disassembling and replacing the upper and lower molds. When it is necessary to process sheet metal parts of multiple different shapes, it is necessary to disassemble the upper mold 76 and the lower mold 73 and replace them with a new set of upper and lower molds. The specific disassembly method is as follows: start the electric lifting rod 20 to shorten its output end, the electric lifting rod 20 pulls the pressurizing slide bar 21 to make it rise, the pressurizing slide bar 21 draws the air inside the support cylinder 23 into the pressurizing cylinder 22, and the air pressure inside the support cylinder 23 gradually decreases, so the support force of the support slide bar 24 on the second slide 10 gradually decreases, the upper mold 76, the first slide 9 and the second slide 10 slowly descend due to gravity, and finally the upper mold 76 descends to the top of the lower mold 73 and combines with the lower mold 73. Then use a wrench to loosen the bolt 773 to release the fixed connection between the fixing seat 772 and the second slide seat 10, and pull the driven key shaft 77 to separate the driven key shaft 77 from the upper mold 76, and then start the electric push column 18, which pushes the lower mold 73, the upper mold 76 and the first bracket 5 to move together in the direction away from the second bracket 6. During the movement, the slide groove sleeve 731 on the side of the lower mold 73 close to the first output shaft 72 is separated from the first output shaft 72 and pulled out from the second bracket 6, the upper mold 76 is separated from the transmission key shaft 75, and after moving to the farthest position, manually push the first bracket 5 to separate the short shaft 732 from the lower mold 73. At this time, the upper mold 76 and the lower mold 73 have been disassembled, and the old upper mold 76 and the lower mold 73 are clamped by a robot, and then replaced with new upper mold 76 and lower mold 73.

[0039] The installation and disassembly methods of the upper mold 76 and the lower mold 73 are similar, as follows: use a robot to clamp the upper mold 76 and the lower mold 73 combined together, and move them in the direction close to the second bracket 6. During the movement, the slide sleeve 731 of the lower mold 73 close to the first output shaft 72 passes through the second bracket 6 and is plugged into the first output shaft 72. The upper mold 76 is plugged into the transmission key shaft 75, and then the first bracket 5 is pushed to insert the short shaft 732 into the slide sleeve 731 adjacent to it, and the driven key shaft 77 is pushed so that its end is plugged into the upper mold 76, and the bolt 773 is tightened with a wrench to fix the fixed seat 772 on the side of the second slide seat 10. The purpose is to prevent the position of the driven key shaft 77 from shifting during the flipping process of the upper mold 76. After the upper mold 76 and the lower mold 73 are installed, the electric lifting rod 20 is started to extend its output end, and the electric lifting rod 20 pushes the air inside the pressurized gas cylinder 22 into the supporting gas cylinder 23 through the pressurized slide bar 21. The air pressure inside the supporting gas cylinder 23 increases, causing the supporting slide bar 24 to rise, and the supporting slide bar 24 pushes the first slide seat 9, the second slide seat 10 and the upper mold 76 to rise. Finally, the upper mold 76 is reset, and the first gear 744 is meshed with the second gear 746, completing the installation of the upper mold 76 and the lower mold 73.
