Description

Technical Field

[0001] This utility model relates to the field of building electromechanical installation, and in particular to a rapid punching device for electromechanical installation hanger steel. Background Technology

[0002] Building pipe hangers are devices used to support and fix various pipes within a building. By bearing the weight of the pipe itself and the fluid inside, the hangers ensure that the pipes do not sag or deform due to gravity, guaranteeing the stability and safety of the piping system. Hangers are typically made of structural steel (such as angle steel and channel steel) and fixed to the building structure by welding or bolting. They provide reliable support, keeping the pipes in a fixed position and posture, preventing displacement, and can withstand significant pipe weight and external forces. They are suitable for pipes with large diameters and heavy weights, such as fire-fighting water pipes and large air-conditioning chilled water pipes.

[0003] When assembling hangers on-site, steel profiles need to be punched. Currently, the steel profiles are usually placed on supports, and the punch is driven down by a drive mechanism to achieve punching. The problems with this method are as follows: First, the circular waste generated during punching is scattered everywhere, affecting the cleanliness of the on-site work environment and requiring centralized cleaning and collection; Second, the supports for the steel profiles are usually of fixed specifications. When punching through holes of different sizes, the entire support needs to be replaced, which is cumbersome and affects the processing efficiency of the hangers. This needs to be improved.

[0010] Preferably, the upper end face of the cylinder housing is provided with an annular handle, which is fixedly connected to the housing by screws.

[0011] Preferably, a square groove is provided below the notch on the side of the circular groove. This square groove is designed to facilitate the gripping of the bottom surface of the mold core seat with fingers.

[0012] The beneficial technical effects of this utility model are:

[0013] (1) This utility model installs blanking die cores of different specifications by setting a die core seat, and sets a notch and a square groove on the side of the circular groove that accommodates the die core seat.

Detailed Implementation

[0021] Example 1, see appendix Figure 2-3A rapid punching device for electromechanical installation hanger steel profiles includes a U-shaped frame 1, a cylinder, and a cylindrical die core seat 2. The die core seat has a central assembly hole 21, and an annular boss 22 at the lower end of the assembly hole. A punching die core is fitted into the assembly hole, and the annular boss 22 provides axial restraint for the punching die core, ensuring it is securely fitted into the die core seat 2. The punching die core has a central punching through hole, the size of which is the same as the size of the pre-punched hole in the steel profile. A punch 112 is coaxially connected to the end of the piston rod 111 of the cylinder, and the punch 112 can extend into the punching through hole. The cylinder is fixedly mounted on the upper part of the U-shaped frame 1, and a support platform 12 is provided on the lower part of the U-shaped frame 1 to prevent the punch from being inserted. The support platform 12 has a circular groove 121 in the middle of the steel profile. A notch 122 is provided between the end face of the support platform and the circular groove. A blanking hole 123 is provided at the center of the bottom of the circular groove 121. The blanking hole and the circular groove form a limiting step. The mold core seat 2 is fitted into the circular groove 121. Part of the side of the mold core seat 2 and the ground are exposed at the notch 122. It can be removed from the circular groove 121 from this point. The bottom surface of the mold core seat 2 supports the limiting step. The punching through hole is arranged vertically opposite to the punch 112. Arc-shaped baffles 13 are provided on the lower end face of the cylinder housing on both sides of the punch 112. The two arc-shaped baffles 13 are used to block the steel profile from above to prevent the steel profile from bouncing significantly after punching and to ensure the safety of the punching operation.

[0022] The cylinder housing has an annular handle 14 on its upper end face, which allows the punching device to be easily lifted, facilitating its movement and assembly / disassembly with the support platform.

[0023] A square groove 15 is provided below the notch 122 on the side of the circular groove 121. The square groove 15 expands the lower space of the notch 122, allowing fingers to fully insert into the bottom surface of the mold core seat 2, making it easier to disassemble under sufficient force.

[0024] When using the punching device in this embodiment, the steel profile is placed on the surface of the support platform 12 and covered with the punching die core. The punching position corresponds to the punching through hole of the punching die core. Then, the cylinder is activated, and the piston rod 111 of the cylinder moves the punch 112 downward and vertically. After the punch contacts the steel profile, it punches out the through hole with its strong punching pressure. The punch 112 passes through the side wall of the steel profile and enters the punching through hole. The generated round waste material is discharged from the discharge hole 123. After the steel profile is punched, it will generate a reverse bouncing force. At this time, the arc-shaped baffles 13 on both sides of the punch 112 block the steel profile from above to prevent the steel profile from bouncing significantly after punching. After the punching is completed, the piston rod 111 is driven by the cylinder to move upward, and the punch 112 leaves the steel profile, completing the punching operation.

[0025] Example 2, see appendix Figure 4-5This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the blanking die core includes a first die core 31 and a second die core 33. The overall size of the first die core and the second die core is the same. The diameter of the second blanking through hole 34 in the second die core 33 is smaller than that of the first blanking through hole 32 in the first die core 31. The punch 112 is fitted inside the piston rod 111. A set screw 113 is provided on the side of the piston rod to fix the punch. The punch 112 inside the piston rod 111 can be fixed or loosened by tightening the set screw 113, which facilitates the quick replacement of punches 112 of different sizes so that the size of the punch matches the size of the blanking through hole inside the die core.

[0026] In this embodiment, the die core seat 2 can be easily removed from the notch 122 to replace the first die core 31 or the second die core 33. By replacing the die core, the device can be adapted to punching operations of through holes of different sizes. This design allows the die core replacement to be completed quickly, simplifies the operation process for punching through holes of different sizes, and improves the punching efficiency of through holes in steel profiles.

[0027] The outer side of the first die core 31 is provided with a first annular groove 41 in the middle, the outer side of the second die core 33 is provided with a second annular groove 42 in the middle, and the outer side of the punching die core is provided with a third annular groove 43 in the middle. The punching die core is provided with annular grooves to reduce the contact area between its outer side and the side of the circular groove 121, so as to avoid the phenomenon that it is difficult to remove due to pressure and tight engagement with the circular groove 121. This facilitates the smooth and convenient installation and disassembly of the punching die core. The function of the annular grooves provided on the first die core 31 and the second die core 33 is the same as that of the annular grooves on the punching die core.

[0028] Example 3, see appendix Figure 1 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the bottom of the U-shaped frame 1 is provided with an assembly support 51. The U-shaped frame 1 is fixedly installed on the operating platform 52 through the assembly support 51. Both ends of the assembly support 51 are provided with through holes, and the operating platform 52 is provided with corresponding through holes. Bolts are installed between the corresponding through holes to fix the assembly support and the operating platform. The lower end of the discharge hole 123 is connected to the discharge pipe 53. A waste box 54 is placed on the ground below the operating platform 52. The lower end of the discharge pipe 53 extends into the waste box 54. The round fertilizer produced by punching slides into the waste box 54 from the discharge pipe.

[0029] This embodiment collects the circular waste generated from punching into the waste bin 54 below the operating platform 52 by connecting the discharge pipe 53 to the port of the discharge channel. This avoids the circular waste generated from punching from scattering everywhere, ensuring the cleanliness of the on-site working environment, and eliminating the need for centralized cleaning and collection.
