Description

Technical Field

[0001] This utility model relates to the field of building decoration equipment technology, specifically to a new type of guillotine for cutting light steel keel. Background Technology

[0002] With the continuous improvement and development of interior building decoration technology, the traditional U-shaped light steel keel, due to its complex construction process and low assembly efficiency, can no longer meet the high-efficiency requirements of modern decoration. The new plug-in quick-rotation keel, however, requires different sizes for different decoration applications during production. Once the keel arrives at the construction site, the numerous size variations necessitate lengthy measurement and classification by construction workers before installation, which is time-consuming and labor-intensive. To address this, we have developed a plug-in assembly light steel keel with cutting slits. Each keel has several evenly distributed cutting slits according to usage requirements. On-site use simply involves cutting the keel along these slits to meet specific size requirements. However, existing cutting tools are primarily electric saws, which are limited by electricity consumption and generate significant noise, impacting the surrounding environment. Summary of the Invention

[0003] To address the problems in the existing technology, this utility model patent designs a new type of guillotine for cutting light steel keel, thereby solving the problem of unsatisfactory application effects of existing light steel keel cutting tools.

[0004] The technical solution adopted by this utility model is as follows: the guillotine includes a cutting blade body and a blade holder. The cutting blade body includes a fixing part and a cutting part, which are fitted together and hinged together. The bottom end of the fixing part is installed on the blade holder. A through keel cutting hole is opened on the fixing part. The shape of the keel cutting hole is the same as the shape of the light steel keel being cut.

[0005] Furthermore, the fixing part is equipped with a keel guide groove on the side away from the cutting part, and the keel guide groove is aligned with the keel cutting hole of the fixing part.

[0006] Furthermore, the cutting part has a keel through hole that is the same as the keel cutting hole of the fixing part. In the initial state, the keel through hole of the cutting part is aligned with the keel cutting hole of the fixing part, and the cutting part is provided with a cutting blade along the edge of the keel through hole.

[0007] Furthermore, a mounting bracket is provided at one bottom end of the keel guide groove, and the mounting bracket is fixed to the lower side of the keel cutting hole of the fixing part of the cutting blade body by bolts.

[0008] Furthermore, both the fixing part and the cutting part of the cutting blade are made of thick metal plates, and their upper rear ends are hinged by a pin, with their upper surfaces aligned. The lower surface of the cutting part is higher than that of the fixing part.

[0009] Furthermore, the upper end of the front end of the fixing part protrudes upward to form a protrusion. A knife handle is hinged to the protrusion on the side near the cutting part. The connection end between the knife handle and the protrusion is a connecting disc. The front end of the connecting disc is eccentrically hinged to the protrusion. The bottom end face of the connecting disc presses against the upper end face of the cutting part.

[0010] Furthermore, a baffle is fixed to the middle of the upper end face of the fixing part by bolts, and the baffle covers the top surface of the cutting part.

[0011] Furthermore, a return spring is connected to the front end of the lower end of the cutting part, and the bottom end of the return spring is fixed to the blade holder.

[0012] Furthermore, a U-shaped limiting block is welded to the front end face of the fixing part near the bottom side, and the limiting block bypasses the front end face of the cutting part.

[0013] Furthermore, the width of the U-shaped groove on the inner side of the limiting block is the same as the thickness of the cut portion of the fixing component.

[0014] Compared with existing technologies, the advancements of this utility model patent's novel light steel keel cutting guillotine are as follows:

[0015] The light steel keel cutting guillotine provided by this utility model patent is not limited by electricity, has low cutting noise, high efficiency, and is easy to use.

[0016] The blade fixing part and the cutting part of the guillotine are respectively opened with keel cutting holes and keel through holes with the same shape as the keel being cut. When cutting, the light steel keel is passed through the cutting holes. The cutting holes limit the keel and prevent the keel from being deformed due to compression during cutting, ensuring that the keel is cut neatly and does not affect the normal insertion and use of the keel.

[0017] The guillotine has a keel guide groove on one side of the blade body for placing the keel, so that the keel can be smoothly inserted into the keel cutting hole of the blade body, improving cutting efficiency; in addition, the keel guide groove is connected to the fixing part by a mounting bracket, making it easy to replace.

[0018] A return spring is installed between the front end of the bottom of the cutting part of the guillotine and the blade holder, which allows the cutting part to automatically and quickly return to its original position after the cutting action is completed. A U-shaped limit block is welded to the front end of the fixed part. The limit block bypasses the cutting part, and its groove width is the same as the thickness of the fixed part and the cutting part. This ensures that the cutting part is always in close contact with the fixed part when cutting, and at the same time, it can make the cutting part return directly to the initial position when the cutting action is completed.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the present invention will be clearly and completely described. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1 , 2 As shown, this utility model patent designs an embodiment of a novel guillotine for cutting light steel keel. In this embodiment, the guillotine includes a cutting blade body, a handle 5, and a blade holder 3. The cutting blade body is mounted on the blade holder 3 and includes a fixing part 1 and a cutting part 2 stacked side by side, both of which are made of thick steel plates. The bottom of the fixing part 1 is fixed to the blade holder 3. The rear ends of the fixing part 1 and the cutting part 2 are hinged near the top, and their upper end faces are flush. A baffle 12 is fixed to the middle of the upper end face of the fixing part 1 by bolts. The baffle 12 is disc-shaped, and its diameter is larger than the thickness of the plate of the fixing part 1. The baffle 12 covers the upper end face of the cutting part 2. The lower end face of the cutting part 2 is higher than the fixing part 1, leaving a cutting gap between it and the blade holder 3.

[0024] The fixing part 1 and the cutting part 2 each have a through keel cutting hole 11 and a keel perforation 21 respectively in the middle of their plates. The keel cutting hole 11 is a C-shaped hole, which is the same as the cross-sectional shape of the keel to be cut, and the hole is about 3mm wide. The diameter of the hole is widened at the bends at both ends. In the initial state, the keel perforation 21 of the cutting part 2 is aligned with the keel cutting hole 11 of the fixing part 1, and the cutting part 2 is provided with a cutting edge along the edge of the keel perforation 21.

[0025] The end of the handle 5 is a connecting disc 51. The upper part of the front end of the fixing part 1 protrudes upward to form a protrusion. The top of the connecting disc 51 is eccentrically connected to the protrusion of the fixing part 1 near the cutting part 2 by a pin. The connecting disc 51 is located on the upper side of the front end of the cutting part 2. The lower end face of the connecting disc 51 presses against the front of the upper end of the cutting part 2. When the handle 5 is pressed down, the connecting disc 51 rotates around the connecting pin at its front end, and its lower end face can press down on the front end of the cutting part 2 to complete the cutting action. There is a notch on the lower side of the cutting part 2 near the front end. A return spring 22 is fixed in the notch. The bottom end of the return spring 22 is connected to the blade holder 3. After the cutting action is completed, the return spring 22 will drive the cutting part to automatically return to its original position. A U-shaped limiting block 13 is welded to the front end face of the fixing part 1 near the bottom side. The limiting block 13 bypasses the front end face of the cutting part 2. The width of the U-shaped groove inside the limiting block 1 is the same as the thickness of the plate body of the fixing part 1 and the cutting part 2, so that the cutting part 2 can always move close to the fixing part 1. At the same time, when the return spring 22 drives the cutting part 2 to return to the original position, the limiting block 13 can limit the cutting part 2 to the initial position.

[0026] The fixing part 1 has a keel guide groove 4 fixed on the side away from the cutting part 2 by means of a mounting bracket 41. The keel guide groove 4 is a U-shaped groove and is positioned directly opposite the keel cutting hole 11 of the fixing part 1. The mounting bracket 41 and the keel guide groove 4 are integrally formed and are connected and fixed to the fixing part 1 by bolts.

[0027] When using the novel light steel keel cutting cutter disclosed in this utility model patent, the light steel keel is directly pushed forward along the keel guide groove 4 into the keel cutting hole 6 and passes through the keel through hole 21 of the cutting part 2. According to the required length, the handle 5 is pressed down. During the rotation of the connecting disc 51 at the front end of the handle 5, the cutting part 2 is pressed down, causing the keel through hole 21 of the cutting part 2 of the cutting blade to be misaligned with the keel cutting hole 11 of the fixing part 1, thus completing the cutting of the light steel keel. Afterwards, the return spring 13 drives the cutting part 2 back to the initial position.

[0028] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
