Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile part processing, in particular to a new energy automobile battery tray numerical control bending and punching equipment. BACKGROUND

[0002] The new energy automobile battery tray, as the core bearing part of the battery pack, directly affects the installation stability, protection performance and vehicle safety of the battery pack. It is usually made of thin-walled metal materials such as aluminum alloy and high-strength steel, needs to be bent into a U-shaped, stepped or other closed or semi-closed structure, and a large number of precise holes need to be processed on the bottom and side surfaces. It has the characteristics of large size, high precision and complex structure. The current new energy automobile industry has strict requirements on the production efficiency and processing precision of the battery tray.

[0003] Although the existing bending and punching integrated machine realizes equipment integration, the bending and punching are still separate processes. All hole processing is completed at the punching station, and then the workpiece is transferred to the bending station for bending forming through the conveying mechanism.

[0004] During the conveying process, the workpiece is prone to position deviation due to vibration and loose clamping, especially for large-size trays. The positioning deviation of single transfer leads to the relative position accuracy of the bending edge and the pre-punching position being out of tolerance, which may cause interference between the hole and the bending edge and make subsequent assembly impossible.

[0005] After the first punching of the thin-walled workpiece, the rigidity decreases, and the clamping force during the second clamping may cause micro-deformation of the workpiece, resulting in nonlinear deviation of the bending angle, which cannot meet the requirements of the battery pack sealing performance on the structural precision.

[0006] The traditional separate process mode has a long waiting time, and the punching and bending cannot be performed in parallel. The processing cycle of a single workpiece is long, and the workpiece transfer and secondary positioning account for a large proportion, which makes it difficult to meet the mass production needs of new energy vehicles.

Therefore, a new energy automobile battery tray numerical control bending and punching equipment is proposed to solve the above problems. SUMMARY

[0008] In view of the deficiencies of the prior art, the present application provides a new energy automobile battery tray numerical control bending and punching equipment, which solves the problems of positioning error accumulation, workpiece secondary clamping deformation, low production efficiency and complex model change adjustment caused by the separate process of the existing bending and punching integrated machine, and cannot meet the high-precision, high-efficiency and flexible production requirements of new energy automobile battery trays.

During the bending process, the side away from the clamping arm 33 between the chuck 37 and the limiting block 34 is not blocked, and the battery tray piece 5 will automatically separate from the clamping and bending forming.

[0043] During the machining process, the numerical control system coordinates the actions of each component in real time, and the punching and bending processes are completed under the same clamping to avoid transportation errors. The double fixation of vacuum adsorption and mechanical clamping solves the problem of deformation of thin-walled parts, and each adjusting mechanism is driven by a screw rod and a motor to realize parameterized control.
