Description

Technical Field

[0001] This invention relates to the field of automotive parts processing, specifically a continuous stamping system for automotive sheet metal parts. Background Technology

[0002] Continuous die stamping of sheet metal parts has been widely used and is a mature technology, but it can only be used for sheet metal parts with small volume structures. However, automotive parts are large in size, and since small sheet metal parts are mostly fed in coils, the material thickness cannot achieve the stamping of large-volume sheet metal parts. At the same time, the conveying distance of the feeding mechanism is short, and existing large-volume automotive sheet metal parts mostly use sheet metal stamping, so feeding cannot be completed. In order to solve the above problems, a continuous stamping system for automotive sheet metal parts was designed. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes a continuous stamping system for automotive sheet metal parts. The technical problem to be solved by this invention is achieved through the following technical solution:

[0004] A continuous stamping system for automotive sheet metal parts includes a sheet metal stacking mechanism that stacks sheet metal and distributes it symmetrically along a direction perpendicular to the horizontal direction. A disassembly mechanism is provided between two sheet metal stacking mechanisms. The disassembly mechanism is connected to a feeding system that conveys sheet metal. The feeding system is connected to a continuous stamping platform. The end of the continuous stamping platform is connected to a finished product conveying line.

[0005] The continuous stamping platform includes an upper template and a lower template. Several mold components are arranged horizontally on the upper template and the lower template. Each mold component is equipped with a clamping component for clamping and conveying the sheet metal. The lower template is equipped with a power component for driving the clamping component to move. The mold component near the feeding system is equipped with a limiting component for limiting the sheet metal.

[0006] Furthermore, the gripping assembly includes grippers symmetrically distributed in the horizontal direction, the grippers are coupled with a guide assembly that drives the grippers to move to avoid the stamping operation of the mold assembly, and the gripping assembly also includes a moving plate that cooperates with the power assembly to drive the grippers.

[0007] Furthermore, the guide assembly includes a lifting platform that is slidably mounted on a movable plate in a vertical direction. The lifting platform is provided with a guide rod that slides in a vertical and horizontal direction and is connected to a gripper. A linkage assembly that is hinged to the end of the guide rod to drive the lifting platform to rise and fall is mounted on the movable plate.

[0008] Furthermore, the linkage assembly includes a first swing arm hinged to the movable plate, a second swing arm hinged to the end of the first swing arm away from the movable plate, a movable block slidably mounted on the upper template hinged to the second swing arm, and a guide rod movably connected to the end of the first swing arm away from the movable plate.

[0009] Furthermore, the power assembly includes a lead screw that is threadedly engaged with the clamping assembly to drive the clamping assembly to convey the sheet metal into the next mold assembly, and the lead screw is coupled with a motor.

[0010] Furthermore, the limiting component includes a limiting block rotatably mounted on the mold assembly, and the mold assembly is provided with a rotating mechanism that drives the limiting block to rotate.

[0011] Furthermore, the rotating mechanism includes a third swing arm hinged to the limit stop, and the third swing arm is hinged to a cylinder mounted on the mold assembly away from the limit stop.

[0012] Furthermore, the limiting block is provided with a notch that matches the end of the plate and has a right angle cross section.

[0013] The beneficial effects of this invention are:

[0014] This invention solves the problem of sheet material feeding by using a linkage assembly, guide rod, and lifting platform to lift and lower the mold assembly to drive the gripper to avoid interference with stamping. At the same time, the gripper, moving plate, and lead screw work together to drive the sheet material into the next mold assembly to complete continuous stamping. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described more clearly and completely below with reference to the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present invention and not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0024] like Figures 1 to 6 As shown, a continuous stamping system for automotive sheet metal parts includes a sheet metal stacking mechanism 1 that stacks sheet metal and distributes it symmetrically along a direction perpendicular to the horizontal direction. A disassembly mechanism 2 is provided between two sheet metal stacking mechanisms 1. The disassembly mechanism 2 is connected to a feeding system 3 that conveys sheet metal. The feeding system 3 is connected to a continuous stamping platform 4. The end of the continuous stamping platform 4 is connected to a finished product conveying line 5.

[0025] The continuous stamping platform 4 includes an upper template 6 and a lower template 7. The upper template 6 and the lower template 7 are respectively provided with a plurality of mold components 8 distributed horizontally. Each mold component 8 is equipped with a clamping component 9 for clamping and conveying the sheet metal. The lower template 7 is provided with a power component 10 for driving the clamping component 9 to move. The mold component 8 near the feeding system 3 is equipped with a limiting component 11 for limiting the sheet metal. There are two sets of clamping components 9 and limiting components 11 arranged perpendicular to the horizontal direction. The clamping component 9 near the finished product conveyor line 5 clamps the finished product onto the finished product conveyor line 5. The mold component 8 is provided with a demolding ejector rod 12 that drives the sheet metal to rise automatically after stamping.

[0026] The clamping assembly 9 includes clamping jaws 91 symmetrically distributed in the horizontal direction. The clamping jaws 91 are engaged with a guide assembly 92 that drives the clamping jaws 91 to move and avoid the stamping operation of the mold assembly 8. The clamping assembly 9 also includes a moving plate 93 that cooperates with the power assembly 10 to drive the clamping jaws 91.

[0027] The guide assembly 92 includes a lifting platform 921 slidably mounted on a moving plate 93 in a vertical direction. The lifting platform 921 is provided with a guide rod 922 that slides in a vertical and horizontal direction and is connected to the gripper 91. The moving plate 93 is hingedly mounted with a connecting rod assembly 923 that is connected to the end of the guide rod 922 to drive the lifting platform 921 to rise and fall. The moving plate 93 is provided with a sliding groove, and the lifting platform 921 has a boss that cooperates with the sliding groove to guide the rise and fall of the lifting platform 921. The mold assembly 8 is provided with a clearance groove 94 to avoid the rise and fall of the gripper 91.

[0028] The linkage assembly 923 includes a first swing rod 924 hinged to the movable plate 93. A second swing rod 925 is hinged to the end of the first swing rod 924 away from the movable plate 93. A movable block 926 is hinged to the second swing rod 925 and slidably mounted on the upper template 6. The end of the first swing rod 924 away from the movable plate 93 is movably connected to the guide rod 922. When the upper template 6 descends, it drives the first swing rod 924 and the second swing rod 925 to swing, thereby pulling the guide rod 922 to move away from the mold assembly 8 in a direction perpendicular to the horizontal. At the same time, the swing of the first swing rod 924 and the second swing rod 925 is transmitted through the guide rod 922 to drive the lifting platform 921 to descend, preventing it from affecting the mold closing of the mold assembly 8. The upper template 6 is provided with a guide rail 95 that cooperates with the movable block 926.

[0029] The power assembly 10 includes a lead screw 101 that is threadedly engaged with the clamping assembly 9 to drive the clamping assembly 9 to transport the sheet metal to the next mold assembly 8. The lead screw 101 is equipped with a motor 102. The lead screw 101 is threadedly engaged with the moving plate 93 so that the gripper 91 can drive the sheet metal into the next mold assembly 8.

[0030] The limiting component 11 includes a limiting block 111 rotatably mounted on the mold component 8. The lower mold component 8 is provided with a rotating mechanism 112 that drives the limiting block 111 to rotate. The lower template 7 is provided with a storage groove 116 for storing the limiting block 111.

[0031] The rotating mechanism 112 includes a third swing rod 113 hinged to the limiting block 111. The third swing rod 113 is hinged to a cylinder 114 mounted on the mold assembly 8 away from the limiting block 111. The cylinder 114 pushes the third swing rod 113 to rotate the limiting block 111 to 90 degrees, so as to cooperate with the plate to limit the position of the plate. When the mold assembly 8 is closed, the cylinder 114 drives the third swing rod 113 to reset, so that the limiting block 111 enters the receiving groove 116. When the mold closing is completed, the gripper 91 transports the plate to the next mold assembly 8 and resets. Then, the cylinder 114 pushes the third swing rod 113 again to rotate the limiting block 111 to 90 degrees.

[0032] The limiting block 111 is provided with a notch 115 that matches the end of the plate and has a right angle cross section; the notch 115 matches the end of the plate to prevent the plate from being unable to accurately position due to inertia, thus affecting the final mold closing.

[0033] In this invention, when the system is working: First step: The chopping mechanism 2 chops the plates stacked by the plate stacking mechanism 1 and conveys them to the mold assembly 8 through the feeding system 3;

[0034] Step 2: Cylinder 114 pushes the third swing arm 113, causing the limit block 111 to rotate to 90 degrees, so as to cooperate with the plate to limit the position of the plate;

[0035] Step 3: Mold assembly 8 closes the mold, cylinder 114 pushes the third swing rod 113 limit block 111 into the storage slot 116, the first swing rod 924 and the second swing rod 925 swing and drive the gripper 91 away from mold assembly 8.

[0036] Fourth step, after mold closing, the first swing rod 924 and the second swing rod 925 drive the gripper 91 to reset, the gripper 91 grips the plate, the lead screw 101 is threaded with the moving plate 93, so that the gripper 91 drives the plate into the next mold assembly 8;

[0037] Step 5: The lead screw 101 and the moving plate 93 are threaded together to drive the gripper 91 to reset. The cylinder 114 pushes the third swing rod 113 to rotate the limit block 111 to 90 degrees, so as to cooperate with the plate to limit the position of the plate.

[0038] Step 6: Repeat the above steps until the gripping component 9 near the finished product conveyor line 5 grips the finished product onto the finished product conveyor line 5.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely prisms of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
