Description

Technical Field

[0001] This application belongs to the technical field of molds, and particularly relates to a forging die for a fire sprinkler head. Background Art

[0002] A fire sprinkler head is an actuator that generates a start signal and performs sprinkler extinguishing when a fire occurs. The forging structure of the fire sprinkler head is as Figure 3 shown.

[0003] The existing Chinese patent with the publication number CN111111061A discloses a fire sprinkler head, including a sprinkler head body and a temperature-sensitive triggering device.

[0004] The sprinkler head body is disclosed in the above-mentioned fire sprinkler head. The structures of the sprinkler head bodies in the existing fire sprinkler heads are generally the same, and they are basically formed by casting. However, the sprinkler head body forms a hollow structure through a bracket, and there is also a structure of a water outlet hole. However, the axis of the hollow structure is perpendicular to the axis of the water outlet hole. To save materials, it is necessary to forge a slot hole when forging the fire sprinkler head. Based on this, the forging die for the fire sprinkler head is improved. Utility Model Content

[0005] The purpose of this application is to provide a forging die for a fire sprinkler head, which can improve the material utilization rate and save materials when forging the fire sprinkler head in view of the above existing technical problems.

[0006] This application provides a forging die for a fire sprinkler head, including:

[0007] An upper die base provided with an upper cavity groove;

[0008] A lower die base provided with a lower cavity groove;

[0009] A side punch needle placed on one side of the upper die base and the lower die base;

[0010] Wherein, the upper cavity groove and the lower cavity groove form a forming cavity. The upper die base is provided with an upper punching groove, and the lower die base is provided with a lower punching groove. The upper punching groove and the lower punching groove form a side punching hole. The side punching hole is connected to the forming cavity. The side punch needle is adapted to the side punching hole. The lower die base is provided with a first flash groove.

[0011] The blank is formed in the forming cavity by the interaction between the upper die base and the lower die base. Through the cooperation of the side punching hole and the side punching pin, when the blank is formed in the forming cavity, the side punching pin is inserted into the side punching hole, and a hole groove is formed at the position of the water outlet hole of the fire sprinkler. The side punching pin is driven by other power devices. The upper cavity groove and the upper punching groove are placed on the upper die base and formed by milling. The lower cavity groove and the lower punching groove are placed on the lower die base and formed by milling. The first flash groove is placed on the lower die base and formed by milling. The first flash groove is convenient for accommodating the flash generated during forging during forging, ensuring the forming of the forging.

[0012] Furthermore, the lower die base is provided with a second flash groove, and the second flash groove is placed in the middle of the lower cavity groove. The upper die base is provided with a third flash groove, and the third flash groove is placed in the middle of the upper cavity groove.

[0013] The second flash groove and the third flash groove correspond to the position of the hollow structure formed by the bracket of the fire sprinkler. After the forging is formed, a thinner flash structure is formed at this position, which is convenient for subsequent cutting. And through the setting of the second flash groove and the third flash groove, the whole forging is coherent, which is convenient for the material flow during forging.

[0014] The second flash groove is provided with a guiding surface, which is convenient for improving the fluidity of the material when the blank is formed through the guiding surface.

[0015] Furthermore, it further includes:

[0016] A flange, placed at the edge of the lower die base and extending towards the upper die base;

[0017] A limiting groove, placed on the outer side wall of the upper die base;

[0018] Wherein, the flange is provided with a first limiting surface corresponding to the limiting groove.

[0019] The flange, the first limiting surface and the limiting groove correspond to each other. By setting the height of the flange, the distance between the upper cavity groove and the lower cavity groove in the upper die base and the lower die base is limited, so that the forging meets the relevant dimensions. By the correspondence between the first limiting surface and the limiting groove, the circumferential positional relationship between the upper die base and the lower die base is limited, ensuring the forming accuracy of the forging.

[0020] Furthermore, the flange is provided with a notch corresponding to the position of the side punching pin.

[0021] By setting a notch on the flange, it is convenient for the side punching pin to move and ensures the cooperation between the flange and the upper die base.

[0022] Furthermore, the lower die base is provided with a first positioning surface, and the first positioning surface is placed on the outer wall surface of the lower die base.

[0023] It is placed on the outer wall surface of the lower die holder through the first positioning surface, facilitating the positioning, installation, and fixation of the lower die holder on the forging press.

[0024] Furthermore, the upper die holder is provided with a clamping part.

[0025] The upper die holder is easily installed on the forging press through the clamping part, making the installation convenient and the structure stable. The clamping part is integrally connected to the upper die holder.

[0026] Furthermore, the clamping part is provided with a second positioning surface, and the second positioning surface is placed on the outer wall surface of the clamping part.

[0027] By placing the second positioning surface on the outer wall surface of the clamping part, it is convenient for the positioning, installation, and fixation of the clamping part.

[0028] Furthermore, the side punch needle includes:

[0029] A first transition surface, which is placed on the side punch needle;

[0030] Wherein, the upper die holder is provided with a second transition surface, and the lower die holder is provided with a third transition surface, and both the second transition surface and the third transition surface correspond to the first transition surface.

[0031] The first transition surface is set on the side punch needle. The first transition surface provides the transition between different diameters of the side punch needle. The first transition surface corresponds to the second transition surface and the third transition surface. When the side punch needle is used for forging the workpiece, the first transition surface cooperates with the second transition surface and the third transition surface.

[0032] Furthermore, the upper die holder includes:

[0033] A groove, which is placed in the upper cavity;

[0034] An upper ejector pin, which is placed on the upper die holder.

[0035] Corresponding convex points are formed on the fire sprinkler head through the groove. When the upper die holder and the lower die holder are opened, through the cooperation of the convex points and the groove on the upper die holder, the fire sprinkler head moves upward with the upper die holder. Then, the fire sprinkler head is ejected and separated from the upper die holder through the upper ejector pin, facilitating the demoulding of the fire sprinkler head. When the upper die holder moves upward, the upper ejector pin will contact the frame on the forging equipment and move relative to the upper die holder. The upper ejector pin has a spring for cooperation, which is used to reset after ejecting the workpiece from the upper die holder.

[0036] The beneficial effects of this application are:

[0037] 1. The blank is formed in the forming cavity through the interaction between the upper die holder and the lower die holder. Through the cooperation of the side punching hole and the side punch needle, the side punch needle is inserted into the side punching hole, and a hole groove is formed at the position of the water outlet hole of the fire sprinkler head through forging.

[0038] 2. The overall coherence of the forging is achieved through the settings of the second flash groove and the third flash groove, facilitating the material flow during forging and subsequent removal.

[0039] 3. The flange, the first limiting surface correspond to the limiting groove. By setting the height of the flange, the distance between the upper cavity groove and the lower cavity groove in the upper die base and the lower die base is restricted, and the circumferential positional relationship between the upper die base and the lower die base is restricted, ensuring the forming accuracy of the forging.

[0048] As Figure 1 、 Figure 2 shown, the embodiments of the present application provide a forging die for a fire sprinkler 001, including:

[0049] An upper die base 100, provided with an upper cavity groove 110;

[0050] A lower die base 200, provided with a lower cavity groove 210;

[0051] A side punching needle 300, placed on one side of the upper die base 100 and the lower die base 200;

[0052] Among them, the upper cavity groove 110 and the lower cavity groove 210 form a forming cavity. The upper die base 100 is provided with an upper punching groove 120, and the lower die base 200 is provided with a lower punching groove 220.

The side punching needle 300 is adapted to the side punching hole. The lower die base 200 is provided with a first flash groove 230.

[0053] Through the interaction between the upper die base 100 and the lower die base 200, the blank is formed in the forming cavity. Through the cooperation of the side punching hole and the side punching needle 300, when the blank is formed in the forming cavity, the side punching needle 300 is inserted into the side punching hole, and a hole groove is formed at the position of the water outlet hole of the fire sprinkler 001. The side punching needle 300 is driven by other power devices. The upper cavity groove 110 and the upper punching groove 120 are placed on the upper die base 100 and are formed by milling. The lower cavity groove 210 and the lower punching groove 220 are placed on the lower die base 200 and are formed by milling. The first flash groove 230 is placed on the lower die base 200 and is formed by milling. Through the first flash groove 230, it is convenient to accommodate the flash generated during forging during forging and ensure the forming of the forging.

[0059] An upper ejector pin 400, placed on the upper die holder 100.

[0060] Corresponding bumps are formed on the fire sprinkler through the groove 170. When the upper die holder 100 and the lower die holder 200 are opened, the fire sprinkler 001 moves upward with the upper die holder 100 through the cooperation of the bumps and the groove 170 on the upper die holder 100, and then the fire sprinkler 001 is ejected and separated from the upper die holder 100 through the upper ejector pin 400, which facilitates the demolding of the fire sprinkler 001.

[0061] Embodiment 2:

[0062] As Figure 1 、 Figure 2 shown, the embodiment of the present application provides a forging die for a fire sprinkler 001. In addition to including the above technical features, further, it further includes:

[0065] Among them, the flange 250 is provided with a first limiting surface 251 corresponding to the limiting groove 140.

[0066] The flange 250, the first limiting surface 251 and the limiting groove 140 correspond to each other. By setting the height of the flange 250, the distance between the upper cavity 110 and the lower cavity 210 in the upper die holder 100 and the lower die holder 200 is limited, so that the forging meets the relevant dimensions. By the correspondence between the first limiting surface 251 and the limiting groove 140, the circumferential positional relationship between the upper die holder 100 and the lower die holder 200 is limited, ensuring the forming accuracy of the forging.

[0067] Furthermore, the flange 250 is provided with a notch 252 corresponding to the position of the side punch 300.
