Abstract
Description
TECHNICAL FIELD
[0001] The application relates to the technical field of battery shell manufacturing, in particular to a battery shell stamping forming device. BACKGROUND
[0002] The battery shell is an important component of the battery, and its main function is to protect the battery module from damage caused by external factors such as external impact, heat and water infiltration.
[0003] In the manufacturing of battery shells, stamping forming technology is widely used, and its basic principle is to use the pressure of the mold and stamping equipment to make the raw material plastically deform in the mold, thereby achieving the required shape and size.
[0004] For example, the patent with publication number CN215697375U discloses a battery shell stamping forming device. The patent is equipped with a second sliding rail, a second sliding block, a mounting plate, a connecting rod and a second spring. Through the cooperation of the second sliding rail and the second sliding block, the connecting rod can slide in the second sliding rail and extrude the second spring to deform while being extruded. This facilitates the reciprocating movement of the connecting rod through the deformation of the second spring, thereby facilitating the automatic unloading of the formed battery shell through the connecting rod.
[0005] In the actual stamping process, after the battery shell is formed in the mold, the contact area between the surface of the battery shell and the mold is usually large. If the formed battery shell is directly vertically ejected, the contact area between the battery shell and the mold remains unchanged or changes little, thereby increasing the friction between the battery shell and the mold. This increased friction not only increases the difficulty of ejection, but also easily causes scratches, wear and even more serious damage to the surface of the workpiece. Scratches and damage not only affect the appearance of the workpiece, but also may reduce its performance and service life.
[0006] Therefore, it is necessary to provide a battery shell stamping forming device to solve the above problems.

DETAILED DESCRIPTION
[0036] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.
[0037] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.
[0038] As shown in Figures 1-2 The present application provides a battery shell stamping forming device, which comprises a frame body 1 and a stamping mechanism 2 arranged at the upper end of the frame body 1. The stamping mechanism 2 is used for stamping work on the battery shell. The stamping mechanism 2 comprises a support table 20 fixedly arranged at the upper end of the frame body 1. A first air cylinder 21 is fixedly arranged at the upper end of the support table 20. The output end of the first air cylinder 21 penetrates the support table 20 and is fixedly connected with a pressure head 22. Thus, the pressure head 22 can move vertically under the drive of the first air cylinder 21, thereby completing the stamping work.
[0039] Meanwhile, a fixing mechanism 3 is arranged at the upper end of the frame body 1. The fixing mechanism 3 is used for placing the battery shell (hereinafter referred to as shell) to be processed. The fixing mechanism 3 comprises a sliding rail 30 fixedly arranged at the upper end of the frame body 1. A sliding block 31 is slidingly arranged on the sliding rail 30. An installation plate 33 is fixedly arranged on the sliding block 31. A hydraulic cylinder 32 is fixedly installed at one end of the sliding rail 30 on the frame body 1. The output end of the hydraulic cylinder 32 is fixedly connected with the installation plate 33. Thus, the installation plate 33 is adapted to slide along the sliding rail 30 under the drive of the hydraulic cylinder 32. Meanwhile, a mold 34 is fixedly arranged on the installation plate 33. A mold cavity 36 is arranged on the mold 34. Thus, the shell can be preliminarily fixed through the mold cavity 36.
[0040] And a baffle 35 is fixedly arranged at one side of the sliding rail 30 on the upper end of the frame body 1. When the mold 34 moves to the end of the baffle 35, the mold 34 is aligned with the bottom of the pressure head 22. Thus, the mold 34 can be quickly positioned.
[0041] It needs to be explained that the die cavity 36 is matched with the pressure head 22, so that the stamping work can be smoothly carried out, so that after the shell is placed on the mold 34, the hydraulic cylinder 32 can be started to push the mounting plate 33 to slide along the slide rail 30, and when the mold 34 on the mounting plate 33 moves to the end of the baffle 35, stop, at this time, the first cylinder 21 can be opened to press the pressure head 22 downward, and then the pressure head 22 can be close to the mold 34 driven by the first cylinder 21, so that the shell can be stamped by the die cavity 36 on the mold 34;
[0042] When the shell is stamped and formed, the shell will be squeezed into the inside of the die cavity 36, in order to facilitate the finished shell to be taken out, as shown in Figures 2-4 The through hole is provided below the pressure head 22, and the ejection mechanism 4 is arranged below the through hole at the lower end of the frame body 1. The ejection mechanism 4 comprises a mounting frame 45 fixedly arranged at the lower end of the frame body 1, a support rod 41 fixedly arranged on the mounting frame 45, a fixed plate 42 rotatably arranged on the support rod 41, two groups of guide sleeves 44 corresponding to the slide rods 43 at the position of the through hole of the frame body 1, and two groups of slide rods 43 slidably arranged in the guide sleeves 44. One end of the slide rod 43 penetrates through the through hole and is hingedly connected to the two ends of the fixed plate 42.
[0043] Meanwhile, a passage is formed at both ends of the die cavity 36. The other end of the slide rod 43 is fixedly provided with a spring 46 inside the guide sleeve 44. The spring 46 is slidably arranged in the guide sleeve 44, and the other end of the spring 46 is fixedly provided with an ejector rod 47. The ejector rod 47 penetrates through the passage and directly contacts the formed shell, so as to facilitate the subsequent ejection operation.
[0044] The output end of the ejector cylinder 40 penetrates through the mounting frame 45 and is fixedly connected to one end of the fixed plate 42, so that one end of the fixed plate 42 can be pushed by starting the ejector cylinder 40, and then the one end of the fixed plate 42 is raised. Since the fixed plate 42 is hingedly connected to the slide rod 43, the slide rod 43 can be pushed vertically upward along the guide sleeve 44 during the raising process. At this time, the slide rod 43 pushes the spring 46 to compress and then pushes the ejector rod 47 vertically upward to contact the shell, so as to eject the air.
[0045] At this time, the other end of the slide rod 43 will move vertically downward along the guide sleeve 44 with the ejector rod 47 driven by the fixed plate 42. Conversely, when the cylinder drives one end of the fixed plate 42 to fall, the ejector rod 47 will be vertically downward driven by the slide rod 43, and the other end of the fixed plate 42 will be raised with the falling of one end of the fixed plate 42, so as to drive the ejector rod 47 to move vertically upward along the guide sleeve 44 by driving the other end of the slide rod 43.
[0046] When the shell is punched before forming, first move the mold 34 to the end of the baffle 35 and stop, at this time the ejector cylinder 40 pushes the ejector rod 47 flush with the inside of the mold cavity 36, when the shell is formed, at this time the ejector rod 47 is flush with the inside of the mold cavity 36, when the shell needs to be loosened, the ejector cylinder 40 can be started to drive the fixed plate 42 at both ends to be alternately raised, so that the two end sliding rods 43 push the ejector rod 47 through the channel to alternately eject the two ends of the formed shell, and then the shell can be smoothly loosened from the mold cavity 36, so that when the staff takes out the shell, the friction between the shell and the mold cavity 36 is reduced, and the possibility of scratches and damage is reduced.
[0047] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
