Description

Technical Field

[0001] This utility model relates to the field of fire door steel plate technology, and in particular to an integrated device for bending and cutting fire door steel plates. Background Technology

[0002] Fire door steel plates refer to the steel used to make fire door frames and doors. They are usually made of high-quality cold-rolled or hot-rolled steel plates. These steel plates have excellent strength and fire resistance, and can withstand the impact of fire and delay the spread of fire. The thickness and specifications of fire door steel plates vary depending on different fire protection levels and requirements. For example, the thickness of the steel plate for the door frame is usually 1.2mm or more, while the thickness of the door leaf must also meet the corresponding safety requirements. When bending fire door steel plates, an integrated bending and cutting device for fire door steel plates is needed to meet people's needs.

[0003] Most fire door steel plate bending and cutting integrated devices on the market currently lack a positioning and fixing mechanism when bending and cutting fire door steel plates. This causes the fire door steel plates to shake during bending and cutting, thus affecting the cutting effect. At the same time, existing bending and cutting integrated devices are not convenient for unloading the cut fire door steel plates, thereby increasing the labor intensity of operators.

[0005] In view of the fact that most fire door steel plate bending and cutting integrated devices on the market lack a positioning and fixing mechanism when bending and cutting fire door steel plates, the fire door steel plates shake during bending and cutting, thus affecting the cutting effect. At the same time, the existing bending and cutting integrated devices are not convenient for unloading the cut fire door steel plates, thus increasing the labor intensity of operators. Therefore, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an integrated device for bending and cutting fireproof door steel plates.

[0007] To solve the above technical problems, this utility model provides the following technical solution: an integrated device for bending and cutting fireproof door steel plates, comprising a device housing, which includes a welding plate. The welding plate is fixedly installed on a side wall of one side of the device housing.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1: Refer to Figures 1-4This is the first embodiment of the present invention. This embodiment provides an integrated bending and cutting device for fire door steel plates. It addresses the problem that most existing integrated bending and cutting devices for fire door steel plates on the market lack a positioning and fixing mechanism during bending and cutting, causing the fire door steel plate to shake and affecting the cutting effect. Furthermore, existing integrated bending and cutting devices are inconvenient for unloading the cut fire door steel plates, increasing the labor intensity of operators. The device includes a housing 1, which includes a welding plate 101. The welding plate 101 is fixedly installed on one side wall of the housing 1. A first support plate 102 is installed on the side wall of the welding plate 101, and the bottom end of the first support plate 102 is fixed. A first hydraulic cylinder 1021 is installed, and a cutting tool 1022 is fixedly installed at the bottom end of the first hydraulic cylinder 1021. A second support plate 103 is installed on the side wall of one side of the welding plate 101. A rectangular hole 104 is opened at the top of the device box 1, and arc-shaped blocks 105 are installed on the side walls at both ends of the rectangular hole 104. A first fixing plate 106 is installed at the top of the device box 1, and a first roller body 107 is installed at the end of the first fixing plate 106 that is close to each other. A discharge groove 109 is opened on one side wall of the device box 1, and a guide plate 1091 is fixedly installed at the bottom end of the discharge groove 109. A second hydraulic cylinder 1031 is fixedly installed at the bottom end of the second support plate 103, and a pressing rod 1032 is fixedly installed at the bottom end of the second hydraulic cylinder 1031.

[0031] The movable adjustment mechanism 2 includes a first groove 201, which is located at the top of the device housing 1. A mounting block 202 is provided inside the first groove 201, and a third support plate 203 is fixedly mounted on the top of the mounting block 202. A second fixing plate 204 is fixedly mounted on the top of the third support plate 203, and a second roller body 2041 is mounted on one end of the second fixing plate 204 that is close to each other. A threaded hole 205 is provided inside the mounting block 202. A lead screw body 206 that passes through the threaded hole 205 is rotatably mounted inside the first groove 201 through a bearing, and the lead screw body 206 is threadedly connected to the threaded hole 205.

[0032] A sliding groove 207 is provided on one side wall inside the first groove 201, and a slider 208 is provided inside the sliding groove 207. The side wall of the slider 208 is fixedly connected to the side wall of the mounting block 202.

[0033] The specific working principle is as follows: when it is necessary to position and fix the fire door steel plate, firstly, the main body 206 of the lead screw is rotated, and the main body 206 is threadedly connected to the threaded hole 205. Through the cooperation of the sliding groove 207 and the slider 208, the main body 206 of the lead screw rotates, which drives the mounting block 202 to slide on the outer wall of the main body 206 through the slider 208 and the sliding groove 207. This allows the mounting block 202 to slide and adjust the distance between the third support plate 203 and the second fixing plate 204. In turn, the second fixing plate 204 slides to position and fix the fire door steel plate, thereby preventing the fire door steel plate from shaking when bending and cutting, which would affect the performance of the bending and cutting integrated device.

[0034] Example 2: Refer to Figures 1-4 This is the first embodiment of the present invention, which provides an integrated bending and cutting device for fire door steel plates. This device addresses the shortcomings of most existing integrated bending and cutting devices for fire door steel plates on the market, which lack a positioning and fixing mechanism during bending and cutting. This causes the fire door steel plate to shake during the bending and cutting process, affecting the cutting effect. Furthermore, existing integrated bending and cutting devices are inconvenient for unloading the cut fire door steel plates, thus increasing the labor intensity of the operators. The limiting and fixing mechanism 3 includes a rectangular frame 301, which is fixedly installed on the side wall of one side of the device housing 1. The inner wall of the rectangular frame 301 is equipped with a guide rail 303, and a guide block 304 is provided inside the guide rail 303. A limiting plate 305 is fixedly installed at the end of the guide block 304 away from the guide rail 303. A through hole 302 is opened on the side wall of one side of the rectangular frame 301. A door panel body 108 is hinged to the side wall of one side of the device housing 1, and a handle body 1081 is installed on the side wall of one side of the door panel body 108.

[0035] A spring body 306 is installed on one side wall inside the rectangular frame 301, and one end of the spring body 306 is fixedly connected to one end of the limiting plate 305. A push rod 307 with a through hole 302 is fixedly installed on one side wall of the limiting plate 305.

[0036] The specific working principle is as follows: when it is necessary to unload the cut fire door steel plate, the unloading groove 109 is opened by rotating the door panel body 108 through the design of the guide plate 1091, and the fire door steel plate is unloaded through the rectangular hole 104. At the same time, through the cooperation of the guide rail 303 and the guide block 304, and by pushing the push rod 307, the limiting plate 305 slides through the guide block 304 inside the guide rail 303 and squeezes the spring body 306 to deform. Then, the elastic recovery of the spring body 306 drives the limiting plate 305 to position and fix the door panel body 108, so that the operator can open the door panel body 108 and unload through the guide plate 1091.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
