Description

Technical Field

[0001] This utility model relates to the field of stamping production line technology, and in particular to an automatic loading and unloading device for sheet metal stamping. Background Technology

[0002] For stamping of workpieces that require multiple stamping processes, the traditional stamping method is to perform a single stamping for each stamping process of the workpiece. That is, a punch press and a set of stamping dies are used to complete one stamping process. This means that workpieces requiring multiple stamping processes need to be stamped by multiple punch presses, and each stamping process requires staff. Therefore, there are problems such as high labor demand and low utilization rate of stamping machines.

[0003] To improve the utilization rate of stamping machines and reduce labor costs, existing technologies also employ multi-station stamping equipment to stamp workpieces requiring multiple stamping processes. For example, a multi-station stamping die for hardware processing disclosed in patent announcement number CN211489297U has multiple stamping lower dies arranged sequentially at intervals on its worktable, and an upper stamping die is installed at the drive end of the stamping machine corresponding to each stamping lower die. During operation, the workpiece passes through multiple stamping dies sequentially to complete multiple stamping processes, and the drive end of the stamping machine drives all stamping upper dies to move synchronously, thus enabling multiple workpieces to be stamped simultaneously.

[0004] Among them, the Chinese utility model patent with patent number ZL202323084799.0 and patent name: "An Automatic Pipe Bending and Stamping Processing Equipment" specifically discloses the following technical solution: An automatic pipe bending and stamping processing equipment, which includes an automatic feeding device, a pipe bending device, a multi-station stamping device, and a material transfer device; the automatic feeding device can evenly arrange and convey the products to be processed to the clamping position, and the automatic feeding device includes a lifting hopper, a conveying mechanism disposed on the upper side of the lifting hopper, a storage plate inclinedly disposed on one side of the conveying mechanism, a pushing mechanism disposed on the opposite side of the storage plate, and a material storage plate disposed on the bottom of the storage plate. The lifting mechanism of the part is used to push the product to be processed on the conveying mechanism to the storage plate by the pushing mechanism, and then lift the product to be processed to the clamping position by the lifting mechanism; the bending device includes a wheel mold and a bending mechanism, which can bend the product to be processed along the outer edge of the wheel mold; the transferring device includes three clamping mechanisms that are evenly distributed and can move laterally, which can sequentially transfer the product to be processed to the bending device and the stamping device, wherein the distance between the clamping position of the product to be processed on the automatic feeding device and the bending device, and the distance between the bending device and the stamping device are consistent with the distance between the three clamping mechanisms.

[0005] When the above-mentioned automatic pipe bending and stamping equipment is working, the automatic feeding device will transport the pipe to the designated position, and then the transfer device will transfer the pipe to the bending device and the stamping device in sequence for bending, punching and punching operations respectively.

[0006] It should be noted that the aforementioned automatic pipe bending and stamping equipment still has the following shortcomings, specifically:

[0007] Defect 1: Due to the lack of automatic unloading components, the workpieces that have completed the final stamping process cannot be unloaded automatically, resulting in low automation and low unloading efficiency.

[0008] Defect 2: The automatic feeding device of this automatic tube bending and stamping equipment is not suitable for sheet metal parts feeding operations, that is, it is not suitable for multi-process stamping of sheet metal parts. Utility Model Content

Detailed Implementation

[0032] The present invention will now be described in conjunction with specific embodiments.

[0033] Example 1, as Figure 1 As shown, an automatic loading and unloading device for sheet metal stamping is applied to a multi-station stamping equipment. The multi-station stamping equipment is equipped with several stamping dies arranged at intervals from left to right and moving synchronously.

[0034] Among them, such as Figure 1 and Figure 5 As shown, the automatic loading and unloading device for sheet metal stamping includes an automatic loading component 1 and a workpiece transfer component 2. The workpiece transfer component 2 includes an X-axis drive linear module 21 that moves horizontally in the left and right direction. The drive end of the X-axis drive linear module 21 is equipped with an X-axis movable frame 22. The X-axis movable frame 22 is equipped with a plurality of workpiece gripping mechanisms 23 arranged sequentially from left to right.

[0035] Furthermore, such as Figure 1 and Figure 6 As shown, the automatic loading and unloading device for sheet metal stamping also includes an automatic unloading component 3, and the workpiece transfer component 2 is located between the automatic loading component 1 and the automatic unloading component 3; the automatic unloading component 3 includes an unloading bracket 31 and an unloading conveyor belt 32 installed at the upper end of the unloading bracket 31, and an unloading robot 33 is installed at the upper end of the unloading bracket 31 on the upper side of the unloading conveyor belt 32.

[0036] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown, the automatic feeding assembly 1 includes a feeding bracket 11, which is equipped with a sheet metal feeder 12, a sheet metal positioning mechanism 13, and a feeding robot 14 located between the sheet metal feeder 12 and the sheet metal positioning mechanism 13. The feeding robot 14 includes a feeding drive linear module 141 mounted on the upper end of the feeding bracket 11 and moving horizontally. The driving end of the feeding drive linear module 141 is equipped with a vertically moving feeding lifting drive cylinder 142. The driving end of the feeding lifting drive cylinder 142 is equipped with a feeding lifting movable frame 143, and the feeding lifting movable frame 143 is equipped with a feeding gripping suction cup 144.

[0037] In the automatic feeding component 1 of this embodiment, during the automatic feeding operation of sheet metal parts, the sheet metal feeder 12 supplies the sheet metal parts to be stamped to the gripping position of the feeding robot 14. When the sheet metal parts to be stamped reach the gripping position of the feeding robot 14, the feeding lifting drive cylinder 142 drives the feeding lifting movable frame 143 to move downward, thereby causing the feeding gripping suction cup 144 installed on the feeding lifting movable frame 143 to grip the sheet metal parts to be stamped at the gripping position. After the feeding gripping suction cup 144 grips the sheet metal parts to be stamped, the feeding lifting drive cylinder 142 drives the feeding lifting movable frame 143 to move upward and reset, thereby causing the gripped sheet metal parts to be stamped to move upward. The feeding lifting drive cylinder 142 drives the feeding lifting movable frame 143 and the gripped sheet metal parts to move upward. After the sheet metal part to be stamped is moved into position, the loading drive linear module 141 drives the loading lifting drive cylinder 142 and the loading lifting movable frame 143 to move toward the sheet metal part positioning mechanism 13, and finally moves the sheet metal part to be stamped by the loading gripping suction cup 144 to above the sheet metal part positioning mechanism 13. After the sheet metal part to be stamped by the loading gripping suction cup 144 moves above the sheet metal part positioning mechanism 13, the loading lifting drive cylinder 142 drives the loading lifting movable frame 143 to move downward, so that the sheet metal part to be stamped is placed on the sheet metal part positioning mechanism 13. The sheet metal part positioning mechanism 13 positions the sheet metal part to be stamped to ensure that the workpiece gripping mechanism 23 of the workpiece transfer assembly 2 can accurately grip the sheet metal part to be stamped.

[0038] In the workpiece transfer assembly 2 of this embodiment, during the transfer of sheet metal parts, the X-axis drive linear module 21 drives the X-axis movable frame 22 to reciprocate. The reciprocating X-axis movable frame 22 drives all workpiece gripping mechanisms 23 to reciprocate synchronously, thereby transferring the sheet metal parts positioned by the sheet metal part positioning mechanism 13 to the lower die of the stamping mold at the first position, and transferring each sheet metal part that has completed the corresponding stamping process to the lower die of the stamping process at the next stamping process position. It should be noted that the workpiece transfer assembly 2 of this embodiment is still prior art, and will not be described in detail here.

[0039] When the automatic sheet metal stamping loading and unloading device of this embodiment is working, the automatic loading component 1 feeds the sheet metal parts to be stamped sequentially into the sheet metal part positioning mechanism 13. The workpiece transfer component 2 transfers the sheet metal parts positioned by the sheet metal part positioning mechanism 13 to the lower die of the first stamping die of the multi-station stamping equipment. The workpiece transfer component 2 transfers each sheet metal part according to the stamping process. After the sheet metal parts have completed all the stamping processes, the unloading robot 33 grabs the sheet metal parts from the lower die of the stamping die corresponding to the last stamping process and transfers the sheet metal parts that have completed all the stamping processes to the unloading conveyor belt 32. The unloading conveyor belt 32 sends out the sheet metal parts that have completed all the stamping processes.

[0040] It should be emphasized that the automatic sheet metal stamping loading and unloading device in this embodiment can automatically unload sheet metal parts that have completed all stamping processes through the automatic unloading component 3, thereby improving the automation level of multi-process stamping operations of sheet metal parts and increasing work efficiency.

[0041] In summary, the automatic sheet metal stamping loading and unloading device of this embodiment has the advantages of novel structural design and high degree of automation, and can be effectively applied to multi-process stamping of sheet metal parts through the above structural design.

[0042] Example 2, as Figure 2 As shown, the difference between this embodiment 2 and embodiment 1 is that the sheet metal feeder 12 includes a hopper slide 122 that is slidably mounted on the feeding bracket 11 via a guide rail slider pair 121. The feeding bracket 11 is equipped with a horizontally moving slide drive cylinder 123 corresponding to the hopper slide 122. The drive end of the slide drive cylinder 123 is drivenly connected to the hopper slide 122.

[0043] The upper end of the hopper slide 122 is equipped with two sheet metal hoppers 124, which are arranged at intervals along the sliding direction of the hopper slide 122 and are used to place sheet metal stacks.

[0044] In addition, a stack lifting mechanism is installed directly below the gripping position of the loading robot 14 on the loading support 11. It should be explained that the stack lifting mechanism in this embodiment 2 may include a vertically moving linear drive module, and the drive end of the linear drive module is equipped with a lifting plate.

[0045] In this second embodiment, when the sheet metal feeder 12 supplies the sheet metal parts to be stamped to the gripping position of the loading robot 14, the operator places the sheet metal parts stack in the sheet metal parts bin 124. Then, the slide drive cylinder 123 drives the bin slide 122 to move, causing the sheet metal parts bin 124 containing the sheet metal parts stack to move to the stack lifting mechanism position. Then, the stack lifting mechanism drives the sheet metal parts stack to rise intermittently, so that each sheet metal part in the stack is lifted and moved to the gripping position of the loading robot 14 in sequence.

[0046] It should be emphasized that two sheet metal parts hoppers 124 are installed on the hopper slide 122 in this embodiment. During operation, when the sheet metal parts hopper 124 loaded with sheet metal parts moves to the position of the stack lifting mechanism, the other sheet metal parts hopper 124 moves to the loading position, at which time the operator can load the sheet metal parts stack.

[0047] Example 3, as Figure 3 As shown, the difference between this embodiment 3 and embodiment 1 is that the sheet metal positioning mechanism 13 includes a sheet metal placement seat 131 installed on the feeding bracket 11 and arranged horizontally.

[0048] The feeding bracket 11 is equipped with four positioning drive cylinders 132 arranged in a ring array around the sheet metal part placement seat 131. Each positioning drive cylinder 132 has a vertically arranged positioning push plate 133 installed at its drive end.

[0049] In this embodiment, when the sheet metal positioning mechanism 13 positions the sheet metal part to be stamped, the loading robot 14 places the sheet metal part to be stamped on the sheet metal part placement seat 131. Then, the four positioning drive cylinders 132 are activated, and each positioning drive cylinder 132 drives the corresponding positioning push plate 133 to move toward the sheet metal part side, so as to achieve accurate positioning of the sheet metal part to be stamped through the pushing action of the four positioning push plates 133.

[0050] Example 4, as Figure 6 As shown, the difference between this embodiment four and embodiment one is that the unloading robot 33 includes an unloading drive linear module 331 mounted on the upper end of the unloading bracket 31 and moving horizontally. The drive end of the unloading drive linear module 331 is equipped with a vertically moving unloading lifting drive cylinder 332. The drive end of the unloading lifting drive cylinder 332 is equipped with an unloading lifting movable frame 333. The unloading lifting movable frame 333 is equipped with an unloading gripping suction cup 334.

[0051] In the automatic unloading component 3 of this embodiment, during the automatic unloading of sheet metal parts, the unloading drive linear module 331 drives the unloading lifting frame 333 and the unloading gripping suction cup 334 to move above the lower die of the stamping mold corresponding to the last stamping process of the multi-station stamping equipment. Then, the unloading lifting drive drives the unloading lifting frame 333 to move down so that the unloading gripping suction cup 334 can grip the sheet metal parts that have completed all stamping processes. Then, the unloading lifting drive cylinder 332 drives the unloading lifting frame 333 to move up and reset. Finally, the unloading drive linear module 331 drives the sheet metal parts gripped by the unloading gripping suction cup 334 to be transferred to the unloading conveyor belt 32.

[0052] Example 5, as Figure 1 and Figure 5 As shown, the difference between this fifth embodiment and the first embodiment is that the workpiece transfer assembly 2 further includes a transfer bracket 24. The upper end of the transfer bracket 24 is equipped with a Y-axis drive linear module 25 that moves horizontally back and forth. The drive end of the Y-axis drive linear module 25 is equipped with a Y-axis movable frame 26. The X-axis drive linear module 21 is installed on the Y-axis movable frame 26.

[0053] For the workpiece transfer assembly 2 in this embodiment 5, before the multi-station stamping equipment performs the stamping action, the Y-axis drive linear module 25 drives the Y-axis movable frame 26 and the X-axis drive linear module 21 to move, so that the workpiece gripping mechanism 23 retracts from the multi-station stamping equipment.

[0054] Example 6, as Figure 5 As shown, the difference between this embodiment six and embodiment one is that each workpiece gripping mechanism 23 includes a gripping lifting drive cylinder 231 that is fastened to the X-axis movable frame 22 and moves vertically. The drive end of the gripping lifting drive cylinder 231 is equipped with a gripping lifting movable frame 232 and a transfer gripping suction cup 233 of the gripping lifting movable frame 232.

[0055] When the workpiece gripping mechanism 23 grips the sheet metal part, the gripping lifting drive cylinder 231 first drives the gripping lifting movable frame 232 and the transfer gripping suction cup 233 to move downwards so that the transfer gripping suction cup 233 grips the sheet metal part; after the transfer gripping suction cup 233 grips the sheet metal part, the gripping lifting drive cylinder 231 drives the gripping lifting movable frame 232 to move upwards and reset.

[0056] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
