Description

Technical Field

[0001] This invention relates to the technical field of battery terminal block production for new energy vehicle batteries, and in particular to a method for forming battery terminal blocks by continuous punching with lifting. Background Technology

[0002] Battery terminals are crucial components in new energy vehicle batteries. However, with the development of new energy vehicles, the use of new energy batteries has increased dramatically. Therefore, high-speed production methods are needed for manufacturing these battery components. Consequently, a progressive continuous punching method using a strip of material has been developed to form battery terminals. This method typically involves placing the strip of material into a progressive die for step-by-step punching to form the battery terminals. However, this method has the following drawbacks:

[0003] 1. The remaining part of the material strip after the battery terminal blocks have been punched out becomes waste material. Therefore, the method of punching out battery terminal blocks by the material strip and progressive die together results in a large amount of material waste, which leads to high production costs for enterprises.

[0004] 2. During the molding process, the strip is in continuous motion, so the lower surface of the strip is always rubbing against the upper surface of the lower die of the progressive die. As a result, the lower surface of the formed battery terminal block is scratched, so the surface accuracy of the lower surface of the battery terminal block is extremely poor and cannot meet the production requirements of high-precision battery terminal blocks.

[0005] 3. After the blanking die is blanked, it falls from the blanking channel to the conveyor surface of the belt conveyor. However, the distance between the conveyor surface of the belt conveyor and the lower end of the blanking channel is far, so it is easy for the blank to flip over when it falls. Therefore, a lot of manual material handling is required when collecting the blank (subsequent production requires the battery terminal blocks to be face up), which affects production efficiency and has a relatively high error rate. Summary of the Invention

[0006] The purpose of this invention is to provide a lifting-type continuous punching method for forming battery terminal blocks in order to overcome the shortcomings of the above-mentioned technologies.

[0007] The present invention discloses a method for forming battery terminal blocks by continuous punching with lifting mechanism, comprising the following steps:

[0008] S1. The block blank in the feeding channel is pressed and falls into the feeding station of the continuous punching die;

[0009] S2. The block blank in the feeding station is conveyed to the first punching station of the continuous punching die by lifting and continuous feeding, so that the block blank is punched into a small annular step on the outer periphery of its lower end.

[0010] S3, the block-shaped blank in the first punching station is conveyed to the second punching station of the continuous punching die in a lifting continuous feeding mode, so that the block-shaped blank is punched to form a large annular step at the outer periphery of the lower end, and a protrusion and a recess hole at the upper end surface and the lower end surface, respectively;

[0011] S4, the block-shaped blank in the second punching station is conveyed to the blanking punching station of the continuous punching die in a lifting continuous feeding mode, so that the middle part of the block-shaped blank is punched to form a battery pole block, and falls into the blanking channel;

[0012] The lifting continuous feeding mode is that the block-shaped blank is clamped by the lifting gripper structure driven by the translational feeding device, so that the block-shaped blank is in a lifted state, and the block-shaped blank in the lifted state is translated by the translational feeding device to above the predetermined blank positioning area, and then the clamping force of the lifting gripper structure is released by the translational feeding device, so that the clamped block-shaped blank is lowered and placed in the predetermined blank positioning area.

[0013] According to the above-mentioned battery pole block forming method of lifting continuous punching, the translational feeding device includes two moving bars arranged along the feeding direction of the continuous punching die, and a driving mechanism for driving the two moving bars to move linearly and reciprocally along the feeding direction of the continuous punching die while relatively approaching or moving away from each other, lifting gripper structures are arranged on the opposite sides of the blank positioning areas of the feeding station, the first punching station, the second punching station and the blanking punching station, respectively; all the lifting gripper structures on one side of the blank positioning areas of the feeding station, the first punching station, the second punching station and the blanking punching station are installed on one moving bar, and all the lifting gripper structures on the other side are installed on the other moving bar.

When the relative two sides of the lifting type clamp jaw structure are relatively moved close to each other, the inner wall of the clamping groove of the lifting type clamp jaw structure abuts against the outer wall of the block-shaped blank, so that the sliding part moves along the inclined axis of the inclined guide part in the first direction, the jaw part is lifted, and the elastic reset part is in a compressed state.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0057] Example:

[0058] like Figure 1 As shown in the figure, the battery terminal block forming method of the present invention designed by the lifting continuous punching method described in this embodiment is mainly realized by a continuous punching die.
