Description

Technical Field

[0001] This utility model relates to the field of steel structure punching technology, specifically a punching equipment for processing light steel structures for building construction. Background Technology

[0002] Light steel frame houses are buildings with light steel keel as the main structural material. They are synthesized by hot-dip galvanized aluminum steel strip through cold rolling technology. They have the characteristics of being lightweight, having strong earthquake resistance, and being quick to construct. During the use and processing of light steel structures, it is necessary to punch holes on their surface.

[0003] An investigation revealed that a utility model patent (publication number: CN211) 9425399U) discloses a punching device for processing light steel structures. The device includes a processing table with a first guide groove on its top. A slider is movably mounted on the inner wall of the first guide groove, and an adjustment groove is provided on the top of the slider. This punching device for light steel structures used in building construction allows the light steel sheet to be punched to pass through a U-shaped slot inside a positioning block. An electric push cylinder is then controlled to move an anti-deviation block along the inner wall of a second guide groove to fix the light steel sheet to be punched. A clockwise rotation of a fastening bolt tightens the bolt along a threaded cylinder, bringing the bottom of the bolt into contact with the surface of the light steel sheet for rapid positioning. This ensures the stability of the punching process and prevents deviation during punching.

[0004] Although the aforementioned patent uses slots and anti-deviation blocks to gather the light steel structure during punching to prevent displacement, the light steel structure mainly undergoes metal-to-metal contact displacement with the processing table surface during displacement adjustment. This makes the light steel structure prone to scratches on its surface due to metal-to-metal friction when pushed back and forth, which can damage the surface anti-rust layer and reduce the service life of the light steel structure.

[0005] Therefore, this utility model provides a punching device for processing light steel structures for housing construction to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects The beneficial effects of this application are as follows: This invention utilizes a rolling support assembly to provide rolling support for light steel profiles, facilitating push-pull adjustments and reducing surface wear. The rolling support assembly employs elastic support, ensuring stability during punching by first pressing down on the profile with a pressure plate. After punching, releasing the pressure allows the support assembly to spring back, enabling the profile to move upwards and resume rolling support for easy push-pull control. Furthermore, the pressure plate in the stamping assembly provides downward and secure pressure to the light steel profile. Combined with the support of the punching die, this achieves stable extrusion, improving the accuracy of the punching process. The pressure plate's covering effect further enhances safety during stamping, preventing warping of the profile and the splashing of stamping debris, thus improving the safety of the device.

[0016] 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.

[0017] like Figure 1-5As shown, this utility model provides a punching equipment for processing light steel structures for housing construction, including a frame 1, with a guide plate 11 on one side of the frame 1; a stamping assembly 2, which is located above the frame 1, with a stamping bottom die 5 fixedly connected to the supporting end of the stamping assembly 2 and a punch 6 fixedly connected to the lifting end of the stamping assembly 2; a second cylinder 3, which is symmetrically distributed on both sides of the stamping assembly 2, and both telescopic ends of the second cylinder 3 are fixedly connected to clamping plates 31, which are used for clamping and limiting the light steel profile; and a support assembly 4, which is used for rolling support of the light steel profile. The highest point of the support assembly 4 is above the highest point of the stamping bottom die 5, and the support assembly 4 is a lifting structure. The rolling support of the light steel profile by the support assembly 4 facilitates the pushing and pulling displacement of the light steel profile and reduces surface damage caused by planar friction.

[0018] Furthermore, the stamping assembly 2 includes a base plate 21, which is fixedly connected to the upper surface of the frame 1. The base plate 21 serves as the support end of the stamping assembly 2. A support frame 22 is fixedly connected to the upper surface of the base plate 21. A first cylinder 23 is fixedly connected to the upper surface of the support frame 22. The lifting end of the first cylinder 23 extends through to the lower part of the support frame 22 and is fixedly connected to an adjusting plate 24. The adjusting plate 24 serves as the lifting end of the stamping assembly 2. By lifting the first cylinder 23, the adjusting plate 24 is lowered, which in turn drives the punch 6 to lower synchronously. This, in conjunction with the stamping die 5 above the base plate 21, completes the punching process of the light steel profile.

[0019] Furthermore, a pressure plate 25 is provided at the bottom of the adjusting plate 24, and a guide shaft 26 is fixedly connected to the upper surface of the pressure plate 25. The guide shaft 26 extends through to the top of the adjusting plate 24, and a first spring 27 is sleeved on the outside of the guide shaft 26. The two ends of the first spring 27 abut against the adjusting plate 24 and the pressure plate 25. When the adjusting plate 24 descends, it first contacts the surface of the light steel profile through the pressure plate 25. Then, when the adjusting plate 24 is pressed down, the first spring 27 is contracted. At this time, the punch 6 continues to descend, which can realize the punching process of the light steel profile. A through hole adapted to the descent of the punch 6 is opened in the center of the pressure plate 25.

[0020] Furthermore, through slots are provided on both sides of the pressure plate 25 corresponding to the clamping plate 31, and the width of the through slots is greater than the width of the clamping plate 31, which facilitates the centered clamping of the clamping plate 31. Thus, the centered clamping of the clamping plate 31 completes the auxiliary limiting of the light steel profile, ensuring the stability of its punching. The pressure plate 25 is located above the support component 4 and the stamping bottom die 5. A material discharge hole is provided in the center of the bottom plate 21, and a rectangular through hole is also provided on the guide plate 11 corresponding to the material discharge hole. The lower part of the rectangular through hole corresponds to the upper surface of the guide plate 11, which facilitates the flow and collection of the punching debris.

[0021] Furthermore, each support assembly 4 includes two rollers 41, with bearing seats 42 rotatably mounted at both ends of the rollers 41. A telescopic rod 43 is fixedly connected to the bottom of the bearing seat 42, and a connecting rod 44 is fixedly connected between the telescopic rods 43 on the same side. A sleeve 45 is fitted around the telescopic rod 43, and a second spring 46 is installed inside the sleeve 45. A limit ring 47 is fixedly connected to the top of the sleeve 45. The rollers 41 are used for rolling support of the light steel profile. The bottom of the telescopic rod 43 is stepped, and the stepped bottom abuts against the second spring 46. The telescopic rod 43 is slidably connected to the center of the limit ring 47. The sleeve 45 is fixedly connected to the upper surface of the frame 1. Through this structure, the support assembly 4 can achieve rolling support of the light steel profile in a non-compression state, which facilitates the push-pull adjustment of the light steel profile.

[0022] Working principle: The light steel profile is placed above the roller 41 and pushed and pulled so that it is moved to the punching position. Then, the first cylinder 23 presses down to drive the adjusting plate 24 to press down. The pressure plate 25 contacts the light steel profile to achieve the downward pressure. At this time, the support component 4 is compressed and contracted until the light steel profile contacts the upper surface of the stamping bottom die 5. Then, the adjusting plate 24 drives the punch 6 to continue to press down. Under the contraction of the first spring 27, the punch 6 contacts the light steel profile, and the surface of the light steel profile is punched. After the punching is completed, the adjusting plate 24 rises and the support component 4 rebounds, driving the light steel profile to move upward.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
