Description

Technical Field

[0001] This utility model relates to the field of punching die technology, and in particular to a punching die for processing manifolds. Background Technology

[0002] A fire manifold is a piping system used in fire protection systems. It is typically used to concentrate and guide the spray water or extinguishing agent at a fire scene. Its main function is to collect the water flow from multiple sprinklers or extinguishing devices to ensure rapid and efficient fire suppression when a fire occurs. Fire manifolds require drilling during processing to facilitate the assembly of other fire protection equipment.

[0003] Because existing manifolds require punching dies to be used for contact and limiting during the punching process to ensure that the subsequent punching position does not deviate, and existing punching dies are generally of a single type, they cannot adaptively adjust the limiting effect according to the actual pipe diameter, resulting in poor overall flexibility of use. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by proposing a punching die for processing manifolds, which improves the problem that existing punching dies are generally of a single type and cannot adaptively adjust the limit according to the actual pipe diameter.

[0005] A punching die for processing manifolds includes a support base and a support shaft: the support base is located directly below the support shaft, the support shaft is provided with an abutment limiting mechanism on its side, an adjusting support mechanism is provided above the support base, and a fixing positioning mechanism is provided on the side of the adjusting support mechanism.

[0006] The abutment limiting mechanism includes a limiting sleeve, a limiting piston rod, a supporting spring, a supporting back plate, and a positioning abutment plate. The limiting sleeve is symmetrically and equally spaced embedded in the outer side wall of the supporting shaft. The limiting piston rod is slidably installed inside the limiting sleeve. A supporting spring connects the limiting piston rod and the bottom inner wall of the limiting sleeve. The protruding end of the limiting piston rod is located outside the limiting sleeve and is connected to the outer side wall of the supporting back plate. A positioning abutment plate is provided on the outer side wall of the supporting back plate away from the limiting piston rod.

[0007] Preferably, the supporting back plate and the positioning contact plate are both configured as a semi-circular structure, and the outer side wall of the positioning contact plate is configured as an arc-shaped structure.

[0008] Preferably, the adjusting support mechanism includes a positioning box, a drive motor, and a reciprocating lead screw. The positioning box is provided on the top outer wall of the support base, and the drive motor is provided on the top outer wall of the positioning box. The output end of the drive motor is connected to the top outer wall of the reciprocating lead screw, and the bottom outer wall of the reciprocating lead screw is rotatably installed with the bottom inner wall of the positioning box.

[0009] Preferably, a limit strip is provided parallel to the side of the reciprocating lead screw, and the top outer wall and bottom outer wall of the limit strip are respectively connected to the top inner wall and bottom inner wall of the positioning box.

[0010] Preferably, a positioning support block is provided through the reciprocating lead screw and the limiting strip. The outer side wall of the positioning support block is provided with a positioning protrusion, and the protruding end of the positioning protrusion is located outside the positioning box. The outer side wall of the positioning protrusion at the protruding end is connected to the outer side wall of the support shaft.

[0011] Preferably, the fixing and positioning mechanism includes a drive cylinder, a fixing and positioning plate, and a mold groove. The top outer wall of the support base is provided with a drive cylinder. The extended end of the drive cylinder is connected to the side outer wall of the fixing and positioning plate. The side outer wall of the fixing and positioning plate away from the drive cylinder is provided with mold grooves at equal intervals. The mold groove is configured as a cylindrical groove structure, and the mold groove and the support shaft are engaged.

[0012] Preferably, the bottom outer wall of the fixing plate is symmetrically provided with positioning T-shaped blocks, and the top outer wall of the support base is provided with two sets of positioning T-shaped grooves. The positioning T-shaped blocks and the positioning T-shaped grooves are slidably installed.

[0013] The beneficial effects of this utility model are:

[0014] 1. The punching die for processing manifolds utilizes a spring assembly combined with a positioning contact plate to limit the movement of the manifold. This transforms the existing fixed-position support of the punching die into an elastic structure, allowing the device to adapt to the opening and positioning needs of fire manifolds of various diameters. Combined with the subsequent cylinder assembly's contact and limiting design, the device can more stably position the fire manifold at the designated location. This ensures the accuracy of subsequent punching processes while maintaining stable positioning of the fire manifold. The overall structure is simple and practical.

[0015] 2. When using the punching die for processing the manifold, the support shaft is designed to be height adjustable through the screw assembly. This allows the device to adjust the support shaft to a suitable support height according to the actual diameter of the fire manifold, thus facilitating the subsequent positioning and installation of the fire manifold. The overall structure is flexible and has good practical effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-5 As shown, a punching die for processing manifolds includes a support base 1 and a support shaft 2: the support base 1 is located directly below the support shaft 2, the support shaft 2 is provided with an abutment limiting mechanism 3 on its side, the support base 1 is provided with an adjusting support mechanism 4 above it, and the adjusting support mechanism 4 is provided with a fixing mechanism 5 on its side.

[0024] The abutment limiting mechanism 3 includes a limiting sleeve 31, a limiting piston rod 32, a support spring 33, a support back plate 34, and a positioning abutment plate 35. The limiting sleeve 31 is symmetrically and equally spaced embedded in the outer side wall of the support shaft 2. The limiting piston rod 32 is slidably installed inside the limiting sleeve 31. The support spring 33 is connected between the limiting piston rod 32 and the bottom inner wall of the limiting sleeve 31. The protruding end of the limiting piston rod 32 is located outside the limiting sleeve 31 and is connected to the outer side wall of the support back plate 34. The positioning abutment plate 35 is provided on the outer side wall of the support back plate 34 away from the limiting piston rod 32.

[0025] When it is necessary to position the manifold to be punched outside the device, simply adjust the manifold to a suitable position and push it horizontally to the outside of the two sets of positioning contact plates 35. Then, the positioning contact plates 35 will automatically move towards the support shaft 2 under the squeezing action of the manifold. Subsequently, the movement of the positioning contact plates 35 will automatically drive the support back plate 34 to move. In turn, the movement of the support back plate 34 will automatically drive the limiting piston rod 32 to slide inside the limiting sleeve 31. At this time, the support spring 33 is in a contracted state due to the squeezing action of the limiting piston rod 32. Simultaneously, the compression of the support spring 33 will generate a force that will automatically push the limit piston rod 32 to move in the opposite direction. The reverse movement of the limit piston rod 32 will automatically drive the support back plate 34 to move, thereby making the positioning contact plate 35 tightly fit with the inner wall of the manifold. In this way, the contact and limiting function of the manifold will be automatically completed without the interference of subsequent manual pushing force. It should be noted that the manifold needs to contact the end of the support shaft 2 during installation so as not to affect the contact and limiting effect of the subsequent fixing mechanism 5.

[0026] Both the support back plate 34 and the positioning contact plate 35 are designed as semi-circular structures, and the outer side wall of the positioning contact plate 35 is designed as an arc-shaped structure. The semi-circular structure of the support back plate 34 and the positioning contact plate 35 makes the overall structure more in line with the shape of the manifold and the arc-shaped structure of the outer side wall of the positioning contact plate 35 makes it easier to install the manifold to the outside of the two sets of positioning contact plates 35 during installation.

[0027] The adjusting support mechanism 4 includes a positioning box 41, a drive motor 42, and a reciprocating lead screw 43. The positioning box 41 is mounted on the top outer wall of the support base 1, and the drive motor 42 is mounted on the top outer wall of the positioning box 41. The output end of the drive motor 42 is connected to the top outer wall of the reciprocating lead screw 43. The bottom outer wall of the reciprocating lead screw 43 is rotatably mounted to the bottom inner wall of the positioning box 41. A limit strip 44 is parallel to the side of the reciprocating lead screw 43. The top and bottom outer walls of the limit strip 44 are connected to the top and bottom inner walls of the positioning box 41, respectively. A positioning support block 45 is provided through the reciprocating lead screw 43 and the limit strip 44. A positioning protrusion is provided on the side outer wall of the positioning support block 45, and the protruding end of the positioning protrusion is located outside the positioning box 41, with the positioning protrusion positioned on the side outer wall at the protruding end. It connects to the outer side wall of the support shaft 2. When the device needs to be adjusted to a suitable support height according to the diameter of the manifold, simply turn on the drive motor 42. When the drive motor 42 is turned on, it will automatically drive the reciprocating screw 43 to rotate. Subsequently, the rotation of the reciprocating screw 43 will automatically drive the positioning support block 45 to move. Due to the setting of the limit bar 44, the reciprocating screw 43 will only drive the positioning support block 45 to achieve a vertical movement trajectory when it rotates. Then, the movement of the positioning support block 45 will automatically drive the positioning protrusion to move, which in turn will drive the support shaft 2 to move. When the support shaft 2 moves to a suitable support height, the drive motor 42 can be turned off directly. It should be noted that the drive motor 42 has a self-locking function. After being turned off, the support shaft 2 can still maintain its support position unchanged.

[0028] The fixing and positioning mechanism 5 includes a drive cylinder 51, a fixing and positioning plate 52, and a mold groove 53. The top outer wall of the support base 1 is provided with a drive cylinder 51. The extended end of the drive cylinder 51 is connected to the side outer wall of the fixing and positioning plate 52. The side outer wall of the fixing and positioning plate 52 away from the drive cylinder 51 is provided with mold grooves 53 at equal intervals. The mold grooves 53 are configured as cylindrical groove structures, and the mold grooves 53 and the support shaft 2 are engaged. The bottom outer wall of the fixing and positioning plate 52 is symmetrically provided with positioning T-shaped blocks 54. The top outer wall of the support base 1 is provided with two sets of positioning T-shaped grooves 55. The positioning T-shaped blocks 54 and the positioning T-shaped grooves 55 are slidably installed.

[0029] When the manifold is installed on the outside of the support shaft 2 and its side needs to be reinforced and limited, simply turn on the drive cylinder 51. When the drive cylinder 51 is turned on, its output end will automatically extend and push the fixing plate 52 towards the support shaft 2. When the fixing plate 52 moves to the bottom of the mold groove 53 corresponding to the support shaft 2, turn off the drive cylinder 51. Note that the drive cylinder 51 has a self-locking function. After it is turned off, the fixing plate 52 can still maintain its position after moving. Thus, the mold groove 53 of the fixing plate 52 provides auxiliary support for the support shaft 2. At the same time, the manifold is pressed against the middle position between the fixing plate 52 and the positioning protrusion by the abutment effect of the outer wall of the side of the fixing plate 52.

[0030] When using this utility model, it should be noted that the support shaft 2 needs to be specially customized according to the length of the manifold to be punched. The length of the support shaft 2 after the fixing plate 52 is attached to the side of the support shaft 2 is the length of the manifold; refer to the appendix of the instruction manual. Figure 1 As shown, a punching groove is provided through the top outer wall of the support shaft 2, which indicates that when the device is combined with existing related punching equipment, the position of the punching groove is the punching position of the punching equipment.

[0031] Before using this device, the entire device needs to be adjusted to a suitable support height according to the diameter of the manifold. At this time, simply turn on the drive motor 42. When the drive motor 42 is turned on, it will automatically drive the reciprocating screw 43 to rotate. Then, the rotation of the reciprocating screw 43 will automatically drive the positioning support block 45 to move. Due to the setting of the limit bar 44, the reciprocating screw 43 will only drive the positioning support block 45 to achieve a vertical movement trajectory when it rotates. Then, the movement of the positioning support block 45 will automatically drive the positioning protrusion to move, which in turn drives the support shaft 2 to move. When the support shaft 2 moves to a suitable support height, the drive motor 42 can be turned off directly. It should be noted that the drive motor 42 has a self-locking function. After it is turned off, the support shaft 2 can still maintain the support position unchanged.

[0032] The manifold to be punched is then positioned outside the device. After adjusting the manifold to a suitable position, it is pushed horizontally to the outside of the two sets of positioning contact plates 35. The positioning contact plates 35, under the pressure of the manifold, automatically move towards the support shaft 2. This movement of the positioning contact plates 35 automatically drives the support back plate 34 to move, which in turn automatically drives the limiting piston rod 32 to slide inside the limiting sleeve 31. At this time, the support spring 33 is in a contracted state due to the pressure of the limiting piston rod 32. Simultaneously, the compression of the support spring 33 will generate a force that will automatically push the limit piston rod 32 to move in the opposite direction. In turn, the reverse movement of the limit piston rod 32 will automatically drive the support back plate 34 to move, thereby making the positioning contact plate 35 tightly fit with the inner wall of the manifold. In this way, the contact and limiting function of the manifold will be automatically completed without the interference of subsequent manual pushing force. It should be noted that the manifold needs to contact the end of the support shaft 2 during installation so as not to affect the contact and limiting effect of the subsequent fixing mechanism 5.

[0033] When the manifold is installed on the outside of the support shaft 2 and its side end needs to be reinforced and limited, it is only necessary to turn on the drive cylinder 51. When the drive cylinder 51 is turned on, its output end will automatically extend and push the fixing plate 52 to move towards the support shaft 2. When the fixing plate 52 moves to the bottom of the mold groove 53 corresponding to the support shaft 2, the drive cylinder 51 can be turned off. It should be noted that the drive cylinder 51 has a self-locking function. After it is turned off, the fixing plate 52 can still maintain its position after moving. Thus, the mold groove 53 of the fixing plate 52 plays an auxiliary support role for the support shaft 2. At the same time, the manifold is pressed against the middle position between the fixing plate 52 and the positioning protrusion by the abutment effect of the outer wall of the side of the fixing plate 52.

[0034] The subsequent punching process was not improved upon; it is a standard existing operating technique and will not be described in detail here.

[0035] It should be noted that the aforementioned drive motor 42 and drive cylinder 51 can be powered by existing operating techniques, whether by using a power supply unit or by an external wire. At the same time, the aforementioned drive cylinder 51 can be designed by adjusting its internal parameters so that its extension length meets the needs of the device operation. These are all existing conventional operating techniques and will not be described in detail here.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
