Description

Technical Field

[0001] The invention belongs to the technical field of stamping feeding devices, and in particular relates to an automatic centering robot feeding device for a stamping line. Background Art

[0002] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the die and deform it, so as to obtain product parts with certain shape, size and performance. Sheet metal, die and equipment are the three elements of stamping. Stamping is a metal cold deformation processing method, so it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing) and also belongs to material forming engineering technology. In stamping, it is generally necessary to cooperate with a feeding device for feeding, thereby assisting the stamping equipment to efficiently perform stamping operations.

[0003] Although there are many kinds of feeding devices at present, there are still some problems. For example, most of the current feeding devices adopt a split design. For example, the feeding system and the feeding system need to be connected through mechanical structures such as slide rails and cylinders. Although this design is convenient for optimizing a single function, it leads to a bloated overall structure, increases the equipment footprint and maintenance difficulty, and the split structure also requires more transmission components (such as plunger hydraulic cylinders and lifting cylinders), resulting in increased energy consumption and maintenance costs. At the same time, the split structure requires electronic control equipment to uniformly regulate it when working in linkage. If a certain link produces a data error, the parameters need to be readjusted as a whole. The operation is cumbersome and the production cost is greatly increased. Summary of the invention

[0035] The loading and unloading mechanism 5 includes a first transmission roller 51, a second transmission roller 52, an output belt 53 and an input belt 54. At least two through grooves are provided on the base 1. The first transmission roller 51 and the second transmission roller 52 are respectively rotatably connected in the two through grooves, and two of them are arranged in parallel. The output belt 53 is arranged between two adjacent first transmission rollers 51, and the input belt 54 is arranged between two adjacent second transmission rollers 52.

[0036] It should be noted that, since most of the current feeding devices adopt a split design, although this design is convenient for optimizing a single function, it leads to a bloated overall structure, increases the equipment footprint and maintenance difficulty, and the split structure also requires more transmission components, resulting in increased energy consumption and maintenance costs. At the same time, the split structure requires electronic control equipment to uniformly regulate it when working in linkage. If a data error occurs in a certain link, the parameters need to be readjusted as a whole, which is cumbersome to operate and also greatly increases the production cost. In order to solve this problem, in this solution, the centering mechanism 3, the stamping mechanism 4 and the loading and unloading mechanism 5 are set as an integrated structure, and the whole can be mechanically linked synchronously, so that the overall structure can be more streamlined, effectively reducing the overall footprint and enclosure difficulty of the device. At the same time, the structure of synchronous mechanical linkage of multiple parts effectively reduces the energy consumption and cost of the overall operation of the device, and improves the accuracy of the operation, avoiding the cumbersome steps caused by the need for electronic control equipment to adjust multiple data one by one, which is simple and efficient;

[0037] By utilizing the setting of the centering mechanism 3, the steering wheel 33 can drive the sliding rod 38 to slide in the limiting slide groove 39 while rotating, and then synchronously drive the centering clamp 310 to work in conjunction, and realize the centering locking of the material and the unlocking operation after stamping. At the same time, the setting of the driven disk 34 is utilized to realize the limitation of the deflection direction of the steering wheel 33 once, further improving the accuracy of material movement during loading, and at the same time, the stamping mechanism 4 and the loading and unloading mechanism 5 can be synchronously linked to realize the stamping and loading and unloading operations of the material, forming an automated and integrated structure, and realizing efficient loading and stamping operations.

[0038] Specifically, in the present embodiment, the present scheme mainly comprises a base 1, a frame 2, a centering mechanism 3, a stamping mechanism 4 and a loading and unloading mechanism 5. When in use, the material is first placed on the input belt 54. At this time, the second transmission roller 52 drives the input belt 54 to move in linkage, and moves the material to the notch at the edge of the steering wheel 33. At the same time, the material is located between two adjacent centering jaws 310. Then the steering wheel 33 rotates, and at the same time drives the sliding rod 38 to slide in the limiting slide groove 39, and then synchronously drives the centering jaw 310 to move in linkage, and locks the material in the center through the centering jaw 310; when the material moves to the stamping mechanism 4, the cam 42 rotates synchronously to push the abutment plate 45 to move in linkage, and then drives the stamping rod 44 to move in linkage to realize the stamping operation of the material; after the stamping is completed, the steering wheel 33 rotates to move the material to the output belt 53. At this time, the centering jaw 310 is in an open state. At this time, the material can be transported out of the steering wheel 33 by the rotation of the output belt 53.

[0040] In this embodiment, the first transmission rod 31 can be synchronously linked with the output shaft of the servo motor 313 through the belt 314 .

[0041] In a further preferred embodiment of the present invention, Figure 1-7 As shown, the loading and unloading mechanism 5 also includes a second driven bevel gear 55, a fourth transmission rod 56 and a second active bevel gear 57.

[0042] In this embodiment, the second active bevel gear 57 is driven to rotate by the fourth transmission rod 56, so that the second driven bevel gear 55 can be synchronously meshed and linked.

Moreover, the first driven gear 510 is engaged between one of the linkage gears 58 and the synchronous gear 59, and the second driven gear 511 is engaged between the other linkage gear 58 and the first driven gear 510.

[0044] In this embodiment, through the arrangement of the first driven gear 510 and the second driven gear 511, both linkage gears 58 can be engaged and linked with the synchronous gear 59, thereby driving the fourth transmission rod 56 to rotate.

The first driving bevel gear 47 is coaxially fixed at the bottom end of the third transmission rod 46, and the first driven bevel gear 48 is coaxially fixed on the second transmission rod 41 and engaged with the first driving bevel gear 47.

[0046] In this embodiment, the third transmission rod 46 drives the first driving bevel gear 47 to rotate, thereby enabling the first driven bevel gear 48 to be engaged and linked, and driving the second transmission rod 41 and the cam 42 to rotate through the first driven bevel gear 48.

[0047] In a further preferred embodiment of the present invention, as Figure 1-2 shown, a driven gear 49 is coaxially fixed at the top end of the third transmission rod 46, and the driven gear 49 is engaged with the driving gear 312.

[0048] In this embodiment, through the engagement and linkage between the driven gear 49 and the driving gear 312, the third transmission rod 46 can rotate synchronously with the first transmission rod 31.
