Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal stamping equipment, specifically a sheet metal stamping bending and forming device. Background Technology

[0002] Sheet metal stamping generally refers to the production of individual stamped parts by taking advantage of the plasticity of metal and using processes such as shearing, stamping, and bending on thin metal sheets of a certain thickness. After the sheet metal stamping is processed, it may need to be bent again.

[0003] An existing patent (publication number: CN216828074U) discloses a sheet metal stamping bending forming device, including a base plate and a rotating plate. Universal wheels are installed at all four ends of the bottom of the base plate, and brake pads are installed on one side of each universal wheel. A support plate is fixed to the center of the top surface of the base plate. A rotating column is rotatably connected to the top of the support plate, and a driven gear is fixed to the top of the rotating column. A first fixing plate is fixed to the left side of the support plate, and a drive motor is installed on the top of the first fixing plate. A drive gear is fixed to the output end of the drive motor, and the drive gear and the driven gear are meshed together. Multiple bending grooves are formed on the top of the rotating plate, and a positioning groove is formed on the upper inner side of each bending groove.

[0004] Although the aforementioned patent, through the cooperation between the driving gear and the driven gear, enables the rotating column to drive the rotating plate to rotate, moving the already bent sheet metal stamping part from under the bending block and moving the sheet metal stamping part to be processed to under the bending block, allowing the worker to remove the bent sheet metal stamping part from the right side of the rotating plate, thus improving the worker's work efficiency, sometimes the sheet metal part gets stuck in the stamping groove after stamping, making it difficult to demold and remove, resulting in lower stamping efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sheet metal stamping bending and forming device, which has the advantage of easy demolding and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal stamping bending forming device, comprising a base and a lifting seat, wherein a mold assembly is provided on the upper surface of the base, the mold assembly comprising a lower mold installed on the upper surface of the base and an upper mold disposed on the bottom surface of the lifting seat, wherein an auxiliary demolding component is provided on the upper surface of the lower mold and the bottom surface of the upper mold, wherein a slot is provided on the upper surface of the lower mold and the bottom surface of the upper mold, and the auxiliary demolding component comprises a cavity, wherein the cavity is slidably connected to the slot;

[0007] The auxiliary demolding assembly also includes a compression cylinder installed inside the cavity. A pressure block is installed at the other end of the compression cylinder, and the pressure block penetrates the cavity. A one-way valve and a drain pipe are installed on the side of the compression cylinder, and the other end of the drain pipe penetrates the cavity.

[0008] Furthermore, the end of the pressure block located inside the compression cylinder is provided with a protrusion.

[0009] The above method ensures that the protrusion at the end of the pressing block can maintain its stability.

[0010] Furthermore, a return spring is provided inside the compression cylinder, with one end of the return spring connected to the compression cylinder and the other end of the return spring connected to the pressure block.

[0011] The above method allows the pressure block to be reset by the elastic force of the reset spring.

[0012] Furthermore, a fixing frame is fixed to the bottom surface of the base and the upper surface of the lifting seat. An auxiliary spring and an auxiliary telescopic rod are provided on the side of the two fixing frames that are close to each other. The other end of the auxiliary spring and the auxiliary telescopic rod are connected to the corresponding cavity.

[0013] The above method allows the cavity to be reset by the elastic force of the auxiliary spring.

[0014] Furthermore, both the bottom surface of the lower cavity and the upper surface of the upper cavity are provided with replenishment tubes for replenishing the solution.

[0015] The above method allows for the replenishment of release agent into the cavity via a replenishment tube.

[0016] Furthermore, multiple uprights are fixed to the upper surface of the base, the uprights pass through the lifting seat, and limit bolts are installed at the ends of the uprights.

[0017] The above solution uses uprights to limit the lifting of the lifting platform, enabling it to move up and down stably.

[0018] Furthermore, a support frame is fixed to the upper surface of the base, and a hydraulic rod is installed on the bottom surface of the support frame. The output end of the hydraulic rod is connected to the fixed frame located above.

[0019] The above scheme uses hydraulic rods to lift and lower the upper fixed frame, which in turn lifts and lowers the upper mold.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0021] This sheet metal stamping bending forming device, by setting an auxiliary demolding component, allows the upper cavity to spray a release agent onto the upper surface of the raw material through a drain pipe during the stamping operation, while the lower cavity sprays the release agent onto the inner wall of the lower mold through a drain pipe. This ensures that the contact surfaces between the raw material and both the upper and lower molds are coated with the release agent, thereby facilitating the separation of the finished product from the mold assembly after the stamping operation and improving the overall demolding efficiency.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a sheet metal stamping bending forming device includes a base 1 and a lifting seat 2. A mold assembly 3 is provided on the upper surface of the base 1. The mold assembly 3 includes a lower mold 301 installed on the upper surface of the base 1 and an upper mold 302 provided on the bottom surface of the lifting seat 2. An auxiliary demolding assembly 4 is provided on the upper surface of the lower mold 301 and the bottom surface of the upper mold 302. A slot is provided on the upper surface of the lower mold 301 and the bottom surface of the upper mold 302. The auxiliary demolding assembly 4 includes a cavity 401, which is slidably connected to the slot. The auxiliary demolding assembly 4 also includes a compression cylinder 402 installed inside the cavity 401. A pressure block 403 is installed at the other end of the compression cylinder 402 and penetrates the cavity 401. A one-way valve 404 and a drain pipe 405 are installed on the side of the compression cylinder 402, and the other end of the drain pipe 405 penetrates the cavity 401.

[0034] Please see Figure 2 , Figure 3 and Figure 4 The end of the pressure block 403 located inside the compression cylinder 402 is provided with a protrusion. The protrusion at the end of the pressure block 403 can maintain the stability of the pressure block 403. A return spring 406 is provided inside the compression cylinder 402. One end of the return spring 406 is connected to the compression cylinder 402, and the other end of the return spring 406 is connected to the pressure block 403. The elastic force of the return spring 406 can drive the pressure block 403 to return to its original position.

[0035] Please see Figure 2 , Figure 3 and Figure 5 A fixing frame 5 is fixed on the bottom surface of the base 1 and the upper surface of the lifting seat 2. An auxiliary spring 6 and an auxiliary telescopic rod 7 are provided on the side of the two fixing frames 5 that are close to each other. The other end of the auxiliary spring 6 and the auxiliary telescopic rod 7 are connected to the corresponding cavity 401. The elastic force of the auxiliary spring 6 can drive the cavity 401 to reset. The bottom surface of the lower cavity 401 and the upper surface of the upper cavity 401 are provided with a liquid replenishment pipe 8 for replenishing solution. The release agent can be replenished into the cavity 401 through the liquid replenishment pipe 8.

[0036] Please see Figure 2 , Figure 3 and Figure 5 Multiple uprights 9 are fixed on the upper surface of the base 1. The uprights 9 pass through the lifting seat 2. Limit bolts 10 are installed at the ends of the uprights 9 to limit the lifting of the lifting seat 2, so that the lifting seat 2 can be lifted stably. A support frame 11 is fixed on the upper surface of the base 1. A hydraulic rod 12 is installed on the bottom surface of the support frame 11. The output end of the hydraulic rod 12 is connected to the fixed frame 5 located above. The hydraulic rod 12 can drive the fixed frame 5 above to lift, thereby driving the upper mold 302 to lift.

[0037] It should be noted that before use, ensure that there is sufficient release agent in cavity 401 to avoid insufficient release agent affecting normal demolding operations during use.

[0038] The working principle of the above embodiment is as follows: the raw material is placed above the lower mold 301, the hydraulic rod 12 drives the upper fixed frame 5 to descend, which in turn drives the upper mold 302 to descend. The descent of the upper mold 302 drives the upper cavity 401 to descend, and the pressure block 403 comes into contact with the raw material. The upper mold 302 continues to descend, and the upper pressure block 403 is squeezed and retracts into the compression cylinder 402. During the retraction process, the release agent inside the cavity 401 is sprayed out through the drain pipe 405 and falls onto the upper surface of the raw material. The upper mold 302 continues to descend, and the upper groove block moves upward until the bottom surface of the groove block is flush with the bottom surface of the upper mold 302.

[0039] At the same time, the raw material comes into contact with the pressure block 403 below, and the raw material is squeezed and continues to fall. The pressure block 403 below retracts into the compression cylinder 402 below. During the retraction process, the release agent inside the lower cavity 401 is sprayed out through the drain pipe 405 and falls onto the upper surface of the lower mold 301. The raw material continues to fall, and the lower groove block moves downward until the upper surface of the groove block is flush with the inner wall of the lower mold 301.

[0040] Through the stamping of the upper mold 302 and the lower mold 301, the raw material completes the stamping and bending forming operation. During the stamping process, since the raw material and the upper mold 302 and the lower mold 301 are sprayed with release agent, the finished product can be easily separated from the mold assembly 3 after the stamping operation, which improves the demolding efficiency of the finished product.
