Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die for an automotive power battery cover. Background Technology

[0002] The stamping die for electric vehicle battery cover production is a high-precision and high-efficiency production tool, specifically designed for forming electric vehicle battery covers. The die includes several key components, such as a base, a screw jack, a servo motor, and a worktable. Each part is responsible for a specific function, and they work together to achieve efficient and precise stamping operations.

[0003] A search revealed that Chinese patent document number CN 220073074 U discloses a punching die for punching holes inside a battery cover mold. The die comprises: a base, an upper pressure plate on top of the base, a cylinder fixedly connected to the top of the upper pressure plate, a lower pressure plate fixedly connected to the top of the base, a punch hole on the top of the lower pressure plate, a housing inside the punch hole, a fixing rod fixedly connected to the bottom of the inner wall of the housing, a lower ejector pin above the fixing rod, an inner groove at the bottom of the lower ejector pin, and a top block fixedly connected to the top of the lower ejector pin. This invention improves the stability of the lower ejector pin's movement by setting the top block so that when the top block is pressed downwards, the lower ejector pin moves downwards, and the fixing rod slides within the inner groove. The spring is compressed, absorbing the impact force, and the elasticity of the spring causes the lower ejector pin to move upwards. The top block pushes out the waste material inside the punch hole, better protecting the mold during subsequent use.

[0004] The stamping dies in the aforementioned patent still have certain shortcomings. In actual operation, the existing battery cover stamping dies mostly rely on manual hand-pushing for feeding the stamping sheet metal, lacking effective sheet metal limiting components. As a result, the sheet metal fed to the top of the die cavity often becomes skewed, making it impossible to make reasonable use of the sheet metal. Sometimes, the skewedness is so severe that the stamped products are unqualified, affecting normal stamping operations. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stamping die for automotive power battery covers. It solves the problem that in actual operation, the feeding of stamping sheet metal in existing battery cover stamping dies is mostly done manually by hand, lacking effective sheet metal limiting components. As a result, the sheet metal fed to the top of the die cavity often becomes skewed, making it impossible to make reasonable use of the sheet metal. Sometimes, the skewedness is so severe that the stamped product is unqualified, affecting normal stamping operations.

[0006] This utility model provides the following technical solution: a stamping mold for an automotive power battery cover, including a stamping support platform, a stamping head provided on the stamping support platform, a fixed connecting plate fixed to the top of the stamping head, a stamping cylinder installed on the top of the stamping support platform, a stamping push rod fixed to the driving end of the stamping cylinder, the stamping push rod slidingly through the top of the stamping support platform and fixedly connected to the center of the top of the fixed connecting plate, a stamping mold cavity provided at the bottom of the stamping support platform, and two stamping auxiliary components symmetrically arranged on both sides of the stamping mold cavity;

[0007] The stamping auxiliary assembly includes lifting slots symmetrically arranged on both sides of the stamping die cavity. A limiting connecting plate is provided at the top of the lifting slot. A sheet metal slot is provided on the side of the limiting connecting plate. A spring telescopic groove is provided on the inner wall of the sheet metal slot. Several connecting holes are evenly arranged on the inner wall of the spring telescopic groove. A limiting abutment plate is inserted into the sheet metal slot. Several limiting connecting rods are evenly and vertically arranged on the side of the limiting abutment plate. The ends of the limiting connecting rods all pass through the connecting holes. A stop spring is fitted onto each limiting connecting rod. One end of the stop spring is connected to the body of the limiting connecting rod, and the other end of the stop spring is connected to the inner wall of the spring telescopic groove. A bottom insert plate is connected to the bottom end of the limiting connecting plate. The bottom insert plate is slidably inserted into the top of the lifting slot. Several telescopic slots are evenly arranged on the bottom wall of the lifting slot. Telescopic rods are slidably inserted into each telescopic slot.

[0008] Preferred technical solution 1: The top end of the telescopic insertion rod is vertically connected to the bottom end of the bottom insertion plate, and a return spring is sleeved on each telescopic insertion rod.

[0009] Preferred technical solution 2: One end of the reset spring is fixedly connected to the telescopic plug rod, and the other end of the reset spring is connected to the bottom wall of the lifting slot.

[0010] Preferred technical solution 3: Limiting rods are evenly arranged around the top of the fixed connecting plate, and the limiting rods all penetrate the top of the stamping support table.

[0011] This solution enables the fixed connecting plate and the stamping head to move more stably under the drive of the stamping cylinder.

[0012] Preferred technical solution four: The limiting connecting plate is located at the top of the stamping support platform and on both sides of the fixed connecting plate.

[0013] This solution ensures that when the stamping cylinder drives the fixed connecting plate and the stamping head downward through the stamping push rod, the fixed connecting plate and the stamping head are not affected by the limiting connecting plate.

[0014] Preferred technical solution five: The width of the bottom insert plate is the same as the inner diameter of the lifting slot, and the bottom insert plate is inserted into the top of the lifting slot.

[0015] This design allows the bottom insert plate to be stopped when it slides downward in the lifting slot, making its vertical reset more stable.

[0016] Compared with the prior art, this utility model provides a stamping die for an automotive power battery cover, which has the following advantages: This utility model has a stamping die cavity set on a stamping support platform, and two stamping auxiliary components are symmetrically arranged on both sides of the stamping die cavity. The limiting connecting plate in the stamping auxiliary component has a plate slot on its side. The plate slot can cooperate with the limiting contact plate to abut and limit the edge of the plate inserted into the plate slot, making the plate fed to the top of the stamping die cavity more straight and stable. The bottom of the limiting connecting plate slides in the lifting slot through the bottom insert plate, so that the surface of the plate that is corrected and limited can fit against the top side of the stamping die cavity during stamping, and will not be affected by the support, ensuring more accurate stamping of the product, effectively improving the pass rate of stamped products, and facilitating user use.

[0023] Please see Figure 1-4 ,

[0024] Example 1: A stamping die for an automotive power battery cover includes a stamping support platform 1, a stamping head 2 on the stamping support platform 1, a fixed connecting plate 3 fixed to the top of the stamping head 2, a stamping cylinder 4 installed at the top of the stamping support platform 1, a stamping push rod 5 fixed to the driving end of the stamping cylinder 4, the stamping push rod 5 slidingly through the top of the stamping support platform 1 and fixedly connected to the center of the top of the fixed connecting plate 3, a stamping die cavity 6 at the bottom of the stamping support platform 1, and two stamping auxiliary components 7 symmetrically arranged on both sides of the stamping die cavity 6.

[0025] The stamping auxiliary component 7 includes lifting slots 701 symmetrically opened on both sides of the stamping die cavity 6. The top of the lifting slot 701 is provided with a limiting connecting plate 702. The side of the limiting connecting plate 702 is provided with a sheet metal slot 703. The inner wall of the sheet metal slot 703 is provided with a spring telescopic groove 704. The inner wall of the spring telescopic groove 704 is evenly provided with a plurality of connecting holes 705. A limiting abutment plate 706 is inserted into the sheet metal slot 703. A plurality of limiting connecting rods 707 are evenly and vertically arranged on the side of the limiting abutment plate 706. The ends of the limiting connecting rods 707 all pass through the connecting holes 705. Abutment springs 708 are sleeved on the limiting connecting rods 707. One end of the abutment springs 708 is connected to the rod body of the limiting connecting rods 707.

[0026] The other end of the contact spring 708 is connected to the inner wall of the spring telescopic groove 704. The bottom end of the limiting connecting plate 702 is connected to the bottom insert plate 709. The bottom insert plate 709 is slidably inserted into the top of the lifting slot 701. Several telescopic slots 710 are evenly opened on the bottom wall of the lifting slot 701. Telescopic rods 711 are slidably inserted into each telescopic slot 710. The top end of the telescopic rod 711 is vertically connected to the bottom end of the bottom insert plate 709. A return spring 712 is sleeved on each telescopic rod 711. One end of the return spring 712 is fixedly connected to the telescopic rod 711, and the other end of the return spring 712 is connected to the bottom wall of the lifting slot 701.

[0027] Example 2: The difference between this example and Example 1 is that, in this example, limit rods are evenly arranged around the top of the fixed connecting plate 3, and the limit rods all penetrate through the top of the stamping support table 1.

[0028] This makes the fixed connecting plate 3 and the stamping head 2 move more stably under the drive of the stamping cylinder 4.

[0029] Example 3: The difference between this example and Example 1 is that the limiting connecting plate 702 is located on the top of the stamping support table 1 and on both sides of the fixed connecting plate 3.

[0030] When the stamping cylinder 4 drives the fixed connecting plate 3 and the stamping head 2 downward through the stamping push rod 5, the fixed connecting plate 3 and the stamping head 2 will not be affected by the limiting connecting plate 702.

[0031] Example 4: The difference between this example and Example 1 is that the width of the bottom insert plate 709 is the same as the inner diameter of the lifting slot 701, and the bottom insert plate 709 is inserted into the top of the lifting slot 701.

[0032] This limits the bottom insert 709 when it slides downward in the lifting slot 701, making its vertical reset more stable.

[0033] In this embodiment, since the existing battery cover stamping molds mostly rely on manual hand-pushing for feeding the stamping sheet during actual operation, and lack effective sheet limiting components, the sheet material fed to the top of the mold cavity often becomes skewed, making it impossible to make reasonable use of the sheet material. Sometimes, the skewed material is so severe that the stamped product is unqualified, affecting the normal stamping process.

[0034] In summary, in practical implementation, when the user needs to transport the sheet metal to the top of the stamping die cavity 6, the stamping cylinder 4 drives the fixed connecting plate 3 downward, so that the fixed connecting plate 3 drives the stamping head 2 to stamp the sheet metal located on the upper part of the stamping die cavity 6, thereby obtaining the stamped product.

[0035] First, the user needs to place the sheet metal into the sheet metal slot 703 on the side of the limiting connecting plate 702 in the stamping auxiliary component 7. Since the side of the sheet metal slot 703 is provided with a limiting contact plate 706, the side of the limiting contact plate 706 is supported by a contact spring 708 sleeved on the limiting connecting rod 707. This allows the two sides of the sheet metal placed in the sheet metal slot 703 to be elastically limited and effectively limited. Since the two limiting connecting plates 702 are arranged parallel to each other on both sides of the stamping die cavity 6, the sheet metal inserted into the sheet metal slot 703 can be straightened, making it straighter at the top of the stamping die cavity 6. This prevents the sheet metal from shifting when it is stamped by the stamping head 2, resulting in a more standard product.

[0036] Simultaneously, a bottom insert plate 709 is slidably inserted into the top of the lifting slot 701 via a bottom insert plate 709 at the bottom of the limiting connecting plate 702. The bottom end of the bottom insert plate 709 is slidably inserted into the telescopic slot 710 via a telescopic rod 711. A return spring 712 is sleeved on the telescopic rod 711, which provides support for the bottom insert plate 709. When the plate in the plate slot 703 is stamped, the plate slot 703 will move down with the plate, thereby causing the bottom insert plate 709 and the telescopic rod 711 to move down in the lifting slot 701. This allows the plate to fit against the top surface of the stamping die cavity 6 at the moment of stamping, ensuring more stable stamping of the plate and preventing irregular deformation due to excessive support, thus improving the stamping quality of the product.
