Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping part production equipment, in particular to an automobile stamping part flanging device. Background Art

[0002] Automotive stamping parts are important metal stamping parts that constitute automotive components. For example, some seat plates, pallets, brackets, etc. require a stamping part flanging device to perform flanging operations on the stamped metal parts during production and processing. This not only facilitates the connection, overlap and styling needs of the stamping parts, but also enhances the strength of the parts and increases their service life. At present, during the flanging process of stamping parts, metal materials are generally placed in a stamping die, and pressure is applied to the material by a press to cause plastic deformation and form a flanging. However, each time the material is loaded, the worker needs to manually place the material between the upper and lower dies of the flanging equipment. After the equipment completes the stamping and flanging, the worker needs to manually remove the workpiece from the lower die. This operation method is not only inefficient, but also poses certain safety risks due to the worker's frequent hand insertion between the upper and lower dies of the equipment. Therefore, a flanging device for automotive stamping parts has been developed. Utility Model Content

[0017] like Figure 1-Figure 2 As shown, a flanging device for automobile stamping parts includes a base 1, a frame 2 with an inverted U-shaped cross-section is fixedly installed on the upper part of the base 1, and the two ends of the bottom of the frame 2 are fixedly connected to the two ends of the upper part of the base 1.

[0018] A lower die 3 is fixedly installed in the middle of the upper part of the base 1, and vertical limit plates 4 are fixedly installed at the front and rear ends of the lower die 3. A lifting mechanism for lifting the workpiece is provided inside the lower die 3. Specifically, a mounting groove 5 with a T-shaped cross-section is provided inside the lower die 3, and two receiving grooves 6 are symmetrically provided in the area between its top surface and the mounting groove 5. The lifting mechanism includes a lifting cylinder 7 fixedly installed vertically on the lower half of the mounting groove 5, the telescopic end of the lifting cylinder 7 is fixedly connected to a slide 8, and the slide 8 is slidably engaged with the upper half of the mounting groove 5. Two lifting blocks 22 are symmetrically fixed on the upper part of the slide 8, which are slidably engaged with the two receiving grooves 6 respectively.

[0019] A vertical die cylinder 9 is fixedly installed in the middle of the upper part of the frame 1. The telescopic end of the die cylinder 9 passes through the top plate of the frame 1 and is fixedly connected to the top of the upper die 10. The bottom of the upper die 10 is provided with a flanging die groove 11 adapted to the lower die 3.

[0020] Horizontal mounting plates 12 are fixedly mounted on the two side panels of the frame 1, with both ends of each mounting plate 12 extending to the exterior of the frame 1. A movable frame 13 with an inverted U-shaped cross-section is slidably mounted on both mounting plates 12. A drive mechanism for driving the movable frame 13 in linear reciprocating motion is disposed between the movable frame 13 and the two mounting plates 12. An electromagnetic chuck 14 for adsorbing workpieces is mounted on the lower portion of the top plate of the movable frame 13.

[0021] In this embodiment, each of the drive mechanisms includes a drive motor 15 horizontally fixedly mounted on the inner side of the mobile frame 13 and a transmission rack 16 fixedly mounted on the upper portion of the mounting plate 12. The drive shaft of the drive motor 15 passes through the side plate of the mobile frame 13 and is equipped with a transmission gear 17 that matches the transmission rack 16. Each of the mounting plates 12 is provided with a limiting slide 18 parallel to the transmission rack 16. Limiting sliders 19 with an I-shaped cross-section and a central portion that slidably engages with the limiting slide 18 are fixedly mounted at the bottom of each end of the mobile frame 13.

[0022] In addition, two vertical driving cylinders 20 are symmetrically fixedly installed on the lower part of the top plate of the mobile frame 13, and the telescopic ends of the two driving cylinders 20 are fixedly connected to the lifting platform 21. The electromagnetic suction cup 14 is fixedly installed on the bottom of the lifting platform 21.

[0023] When the utility model is working, the movable frame is initially located at the loading end of the workpiece, and the lifting platform is lowered by two driving cylinders. After the electromagnetic suction cup at the bottom of the lifting platform contacts the upper surface of the material, the electromagnetic suction cup is energized to adsorb the material, and then the two driving cylinders retract and reset, and the two driving motors drive the transmission gear to rotate. Due to the meshing relationship between the transmission gear and the transmission rack on the mounting plate, the movable frame moves linearly along the two mounting plates until the movable frame moves to between the lower die and the upper die, the two driving motors are temporarily turned off, and the two driving cylinders are extended again. After the bottom of the material contacts the lower die, the electromagnetic suction cup is de-energized, thereby placing the material on the lower die, and then the two driving cylinders retract and reset, and the two driving motors are started to make the movable frame move to the outside of the lower die and the upper die, thereby completing the automatic loading operation.

[0024] The die cylinder extends, gradually moving the upper die downward. The flanging grooves in the upper die engage with the lower die to automatically flanging the material. Once flanging is complete, the die cylinder retracts and resets, moving the upper die upward to its initial position. Simultaneously, the lift cylinder drives two ejector blocks out of the lower die's receiving grooves, lifting the flanged workpiece and freeing it from the lower die. The two drive motors are then reactivated until the machine reaches above the lower die. The two drive cylinders extend, bringing the electromagnetic chuck into contact with the upper surface of the flanging workpiece. The chuck engages and disengages, retaining the workpiece. The two drive cylinders retract and reset, and the two drive motors drive the transmission gears, causing the mobile carriage to "carry" the flanging workpiece to the unloading station. When the electromagnetic chuck is de-energized, the workpiece automatically drops to the unloading station, completing the automatic unloading of the flanging workpiece. The two drive motors then reverse direction, moving the mobile carriage back to the initial loading station. This cycle repeats, completing the batch processing of automated workpieces.

Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
