Description

Technical Field

[0001] This utility model relates to the field of cabinet sheet metal parts technology, specifically a high-efficiency stamping and forming equipment for cabinet sheet metal parts. Background Technology

[0002] Cabinet enclosures are core components in industries such as power, communications, data centers, and industrial automation. With the accelerated construction of infrastructure such as 5G base stations, new energy charging piles, and data centers, the market demand for cabinet sheet metal parts continues to grow. Since most cabinets have heat dissipation requirements, the demand for louvers is particularly large.

[0003] A search revealed a utility model patent with Chinese patent publication number CN205243377U, which discloses an integrated louver structure. This louver body is equipped with several "I"-shaped or "V"-shaped louver slats formed by a single stamping process. The louver slats open outwards and have a convex, curved streamline structure. The spacing between the louver slats is 28-160 mm, and the width of the obstructing surface between the louver slats is 4-80 mm. The louver slats are designed as a "I"-shaped, outward-facing, convex, curved streamline structure with an arc angle of 20-90°.

[0004] As mentioned above, venetian blinds are generally made by one-piece stamping. Therefore, after processing, the slats are embedded in the grooves of the mold. Furthermore, the thickness of the venetian blinds is relatively thin, making them inconvenient to handle and affecting production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a high-efficiency stamping and forming equipment for cabinet sheet metal parts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency stamping and forming equipment for cabinet sheet metal parts, including a base plate, a lower die fixedly installed on the top outer wall of the base plate, a material discharge assembly installed on the top of the lower die, the material discharge assembly including a hinge seat fixedly connected to the upper part of the outer wall of one end of the lower die, a top ring hinged inside the hinge seat, two receiving grooves adapted to the top ring opened on the top outer wall of the lower die, when the top ring enters the two receiving grooves, the top wall of the top ring and the top wall of the lower die remain at the same level, the material discharge assembly also includes a hook plate, the hook plate is located outside the movable end of the top ring.

[0007] As a further preferred embodiment of this technical solution, a support frame is fixedly connected to the outside of the base plate, and a stamping assembly is installed inside the support frame. The stamping assembly includes a hydraulic cylinder fixedly installed on the top of the support frame. An upper die adapted to the lower die is fixedly connected to the output end of the hydraulic cylinder, and one end of the hook plate is fixedly connected to the outer wall of one end of the upper die.

[0008] During the mold splitting process, the finished product can be ejected from the lower mold and automatically slide outward along the slope. The material removal process is convenient and quick, with a sufficiently short time consumption, which helps to improve the working efficiency of the device. The hook plate fixed outside the upper mold is driven to move upward synchronously. Then the hook plate contacts the top ring, and the movable end of the top ring is lifted and moved upward. Then it flips along the hinge seat, and the louvers stuck inside the lower mold will be ejected and then slide outward along the top ring.

[0009] As a further preferred embodiment of this technical solution, four limiting rods are slidably inserted inside the upper mold. The four limiting rods are respectively located at the four corners of the upper mold. The bottom end of each of the four limiting rods is fixedly connected to the same pressure ring. The pressure ring is slidably sleeved on the outside of the lower half of the upper mold. A spring is sleeved on the outside of each of the four limiting rods. The two ends of the four springs are respectively fixedly connected to the upper mold and the pressure ring.

[0010] As a further preferred embodiment of this technical solution, each of the four corner positions of the upper mold is fixedly connected to an extension sleeve, and the four extension sleeves are respectively slidably sleeved on the outside of the four support columns at the bottom of the support frame.

[0011] As a further preferred embodiment of this technical solution, a positioning component is installed on the top of the base plate, and the positioning component is located on one side of the lower mold.

[0012] As a further preferred embodiment of this technical solution, the positioning component includes a support plate fixedly connected to one side of the top outer wall of the base plate, a horizontally arranged positioning frame slidably inserted into the top of the support plate, a rectangular limiting frame provided at the end of the positioning frame away from the support plate, a horizontally arranged extension column fixedly connected to the outer wall of one end of the positioning frame, and a guide frame fixedly connected to the bottom outer wall of the upper mold, the guide frame being slidably connected to the outside of the extension column, and the middle part of the extension column being inclined.

[0013] The sheet metal is placed on top of the lower die and pushed into the positioning frame. Under its constraint, the sheet metal will be in a fixed position. When the upper die moves down, the guide frame fixed at its bottom will also move synchronously. Since the positioning frame can only move horizontally due to the restriction of the support plate, the extension column fixed on it has the same characteristic. When the guide frame moves down, the extension column will be guided to move away from the support plate, thereby preventing the positioning frame from affecting the stamping operation.

[0014] As a further preferred embodiment of this technical solution, the bottom wall edges of the top ring are both set to be arc-shaped.

[0015] This utility model provides a high-efficiency stamping and forming equipment for cabinet sheet metal parts, which has the following beneficial effects: (1) By setting up a material discharge component, the finished product can be ejected from the lower mold during the mold splitting process and automatically slide out along the slope. The material removal process is convenient and quick, and the time consumption is short enough, which is conducive to improving the working efficiency of the device. The hook plate fixed outside the upper mold is driven to move upward synchronously. Then the hook plate contacts the top ring, the movable end of the top ring is lifted and moved upward, and then flipped along the hinge seat. The louver stuck inside the lower mold will be ejected and then slide out along the top ring.

[0016] (2) By setting a positioning component, the plate is placed on the top of the lower die and pushed into the positioning frame. Under its restriction, the plate will be in a fixed position. When the upper die moves down, the guide frame fixed at its bottom will also move synchronously. Since the positioning frame can only move horizontally due to the restriction of the support plate, the extension column fixed on it also has the same characteristics. When the guide frame moves down, the extension column will be guided to move away from the support plate, thereby avoiding the positioning frame from affecting the stamping operation.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 2As shown in Figure 4, in this embodiment, a high-efficiency stamping forming equipment for cabinet sheet metal parts includes a base plate 1. A lower die 3 is fixedly installed on the top outer wall of the base plate 1. A material discharge assembly 5 is installed on the top of the lower die 3. The material discharge assembly 5 includes a hinge seat 501 fixedly connected to the upper part of the outer wall of one end of the lower die 3. A top ring 502 is hinged inside the hinge seat 501. Two receiving grooves 503 adapted to the top ring 502 are opened on the top outer wall of the lower die 3. When the top ring 502 enters the two receiving grooves 503, the top wall of the top ring 502 and the top wall of the lower die 3 remain at the same level. The material discharge assembly 5 also includes a hook plate 504, which is located outside the movable end of the top ring 502.

[0020] The base plate 1 is externally fixedly connected to a support frame 2. The support frame 2 is internally installed with a stamping assembly 4. The stamping assembly 4 includes a hydraulic cylinder 401 fixedly installed on the top of the support frame 2 (this equipment is conventional and will not be described in detail here). The output end of the hydraulic cylinder 401 is fixedly connected to an upper mold 402 that is compatible with the lower mold 3. One end of the top of the hook plate 504 is fixedly connected to the outer wall of one end of the upper mold 402.

[0021] The hook plate 504, fixed to the outside of the upper mold 402, is moved upward synchronously. Then the hook plate 504 contacts the top ring 502, and the movable end of the top ring 502 is lifted and moved upward. Then it flips along the hinge seat 501, and the louver stuck inside the lower mold 3 will be pushed out and then slide outward along the top ring 502. When the upper mold 402 contacts the support frame 2, it stops and moves down a distance so that the top ring 502 enters the receiving groove 503, ensuring that the subsequent placement work can be carried out smoothly.

[0022] like Figure 2 and Figure 4 As shown, four limiting rods 404 are slidably inserted inside the upper mold 402. The four limiting rods 404 are respectively located at the four corners of the upper mold 402. The bottom end of the four limiting rods 404 is fixedly connected to the same pressure ring 406. The pressure ring 406 is slidably sleeved on the outside of the lower half of the upper mold 402. A spring 405 is sleeved on the outside of each of the four limiting rods 404. The two ends of the four springs 405 are fixedly connected to the upper mold 402 and the pressure ring 406, respectively.

[0023] An extension sleeve 403 is fixedly connected to each of the four corner positions of the upper mold 402. The four extension sleeves 403 are slidably sleeved on the outside of the four support columns at the bottom of the support frame 2.

[0024] Subsequently, the pressure ring 406 outside the upper mold 402 first contacts the edge of the material. As the upper mold 402 continues to move downward, the spring 405 between it and the pressure ring 406 is compressed. Its reaction force will act on the material through the pressure ring 406, so that the material is first fixed. Then the upper mold 402 contacts the top surface of the material, and the molding can be completed in conjunction with the lower mold 3.

[0025] like Figure 2 and Figure 3 As shown, a positioning component 6 is installed on the top of the base plate 1, and the positioning component 6 is located on one side of the lower mold 3.

[0026] The positioning component 6 includes a support plate 601 fixedly connected to one side of the top outer wall of the base plate 1. A horizontally arranged positioning frame 602 is slidably inserted into the top of the support plate 601. A rectangular limiting frame is provided at one end of the positioning frame 602 away from the support plate 601. A horizontally arranged extension column 603 is fixedly connected to the outer wall of one end of the positioning frame 602. A guide frame 604 is fixedly connected to the bottom outer wall of the upper mold 402. The guide frame 604 is slidably connected to the outside of the extension column 603, and the middle part of the extension column 603 is inclined.

[0027] The sheet metal is placed on top of the lower die 3 and pushed into the positioning frame 602. Under its constraint, the sheet metal will be in a fixed position. When the upper die 402 moves down, the guide frame 604 fixed at its bottom will also move synchronously. Since the positioning frame 602 is restricted by the support plate 601 to only move horizontally, the extension column 603 fixed on it has the same characteristic. When the guide frame 604 moves down, the extension column 603 will be guided to move away from the support plate 601, thereby preventing the positioning frame 602 from affecting the stamping operation.

[0028] like Figure 1 and Figure 3 As shown, the bottom wall edge of the top ring 502 is set to be arc-shaped, so that the top ring 502 can smoothly enter the receiving groove 503 when it flips towards the lower mold 3.

[0029] This utility model provides a high-efficiency stamping and forming equipment for cabinet sheet metal parts, the specific working principle of which is as follows: When the device is working, the sheet metal is placed on top of the lower die 3 and pushed into the positioning frame 602. Under its constraint, the sheet metal will be in a fixed position. When the upper die 402 moves down, the guide frame 604 fixed at its bottom will also move synchronously. Since the positioning frame 602 is restricted by the support plate 601 to only move horizontally, the extension column 603 fixed on it has the same characteristic. When the guide frame 604 moves down, the extension column 603 will be guided to move away from the support plate 601, thereby preventing the positioning frame 602 from affecting the stamping operation.

[0030] Subsequently, the pressure ring 406 outside the upper mold 402 first contacts the edge of the material. As the upper mold 402 continues to move downward, the spring 405 between it and the pressure ring 406 is compressed. Its reaction force will act on the material through the pressure ring 406, so that the material is first fixed. Then the upper mold 402 contacts the top surface of the material, and the molding can be completed in conjunction with the lower mold 3.

[0031] Finally, the hydraulic cylinder 401 retracts, and the upper mold 402 begins to move away from the material. The hook plate 504, which is fixed outside the upper mold 402, is driven to move upward synchronously. Then, the hook plate 504 contacts the top ring 502, and the movable end of the top ring 502 is lifted and moved upward. Then, it flips along the hinge seat 501, and the louvers stuck inside the lower mold 3 will be pushed out and then slide outward along the top ring 502. When the upper mold 402 contacts the support frame 2, it stops and moves down a certain distance so that the top ring 502 enters the receiving groove 503, ensuring that the subsequent placement work can proceed smoothly.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
