Description

Technical Field

[0001] The present invention relates to the technical field of cutting processing, and specifically to a fine cutting device for channel steel processing in construction projects. Background Art

[0002] Channel steel formwork is mainly used in the concrete pouring process in construction. It can be used as a support formwork to temporarily support the building concrete structure, improving construction efficiency and ensuring the pouring and forming quality of the concrete pouring structure. It can also be used as a component formwork of the channel steel mold for the pouring and forming of concrete components. It can be reused and can realize the batch and standardized manufacturing and forming of concrete components.

[0003] In this regard, Chinese Patent Application No.: 202411482839.3 discloses a fine cutting device for processing channel steel formwork in construction projects, including: a base, on the top surface of which a lifting frame is installed, and a cutting mechanism is installed on the lifting frame; a fixing structure is installed on the top surface of the base, and the fixing structure includes a support mold, the support mold is fixedly installed on the top surface of the base, a mold groove is opened on the top surface of the support mold, a support is fixedly welded on the top surface of the support mold, a pressing mold is slidably installed inside the mold groove, and an electric telescopic rod is fixedly installed on the top surface of the support. The cutting device of the present invention can support and limit the channel steel formwork on the upper and lower sides by setting a lower pressing roller frame and a support roller frame, so that when the channel steel formwork moves inside the fixed block, it can maintain a straight state, ensuring the smoothness of unloading, and reducing the wear on the device and the workpiece, improving the use experience of the device.

[0004] This cutting device supports and fixes the channel steel formwork during the feeding and cutting processes through the fixing structure. However, during this process, it is necessary to directly push the channel steel formwork to slide forward on the fixing structure. Due to the large size and weight of the channel steel formwork, under the action of gravity, a large frictional resistance is generated between the channel steel formwork and the supporting components of the fixing structure, making it inconvenient to push the channel steel formwork to slide on the fixing structure, and large wear is also easily generated between them, greatly reducing the service life of the fixing structure and even causing damage to the channel steel formwork. At the same time, the length of the end of the channel steel formwork to be cut is relatively large, easily resulting in unstable overall center of gravity and inconvenient for stable cutting.

Before processing, the entire discharging structure 3 is moved through the translation mechanism to adjust the distance between the discharging structure 3 and the cutting mechanism 12 according to the required cutting length dimension, and a positioning structure 4 is arranged on the discharging structure 3;

[0039] It should be supplemented that: the base 1, lifting frame 11, cutting mechanism 12, unloading structure 3 and positioning structure 4 used in the present application are all described in detail in the invention patent cited in the background technology, so they will not be repeated here. At the same time, the material guide structure 2 and the feeding assembly 5 in the present application are used to load and push the channel steel template, that is, the loading of the channel steel template can be completed, and the debugging operation of the cutting spacing of the channel steel template can be completed during the loading process. The material guide structure 2 can stably and effectively support the channel steel template during the loading process to ensure the smooth adjustment of the channel steel template and the debugging of the cutting spacing, and stably and effectively limit and fix the channel steel template during the cutting process of the channel steel template to ensure stable and effective cutting of the channel steel template, improve cutting accuracy and efficiency, and the feeding assembly 5 can support and fix the part of the channel steel template to be cut to avoid the cutting end of the channel steel template from tilting during the cutting process, so that the cutting is stable and smooth, and it is easy to use;

[0040] The top surface of the base 1 is provided with a material guide structure 2, which includes a support mold 201, a support member 203 is slidably arranged in a placement cavity 2011 opened on the upper part of the support mold 201, the support member 203 is arranged in cooperation with the pressing mold 202, and the pressing mold 202 is fixedly connected to the telescopic end of the hydraulic cylinder 205 on the bracket 204;

[0041] A feeding assembly 5 is arranged on one side of the material guiding structure 2 . The feeding assembly 5 includes a driving seat 501 . A clamping seat 502 slidably arranged on the driving seat 501 is transmission-connected to a servo motor 503 via a screw rod 5014 .

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the support mold 201 is fixedly connected to a designated position on the base 1, so that the entire material guide structure 2 can be stably installed on the base 1 to ensure stable use. The support member 203 is placed at the upper end portion of the placement cavity 2011 opened on the support mold 201, and a placement platform for placing the channel steel template is formed on the support mold 201, so that the channel steel template is stably placed, which is convenient for subsequent cutting. The embedded cavity 2014 opened on the support mold 201 is provided with an anti-skid protrusion 210, and the anti-skid protrusion 210 is stably installed, so that when the channel steel template contacts the anti-skid protrusion 210, the friction between the channel steel template and the support mold 201 is increased, and the channel steel template is limited and fixed, so as to ensure that the channel steel template does not slide during the cutting process, thereby improving the cutting accuracy and efficiency;

[0043] The moving groove 2012 opened at the upper port part of the placement cavity 2011 on the support mold 201 is slidably connected to the placement frame 2032 integrally designed on the support member 203. When the support member 203 is stressed, the cooperation between the placement frame 2032 and the moving groove 2012 enables the support member 203 to slide smoothly in the placement cavity 2011 of the support mold 201. At this time, the channel steel formwork placed on the support member 203 will contact the support mold 201, and the frictional resistance between the two is used to limit and fix the channel steel formwork. Moreover, the sliding rod bent on the placement frame 2032 is slidably connected to the rod groove 2013 opened on the side wall of the support mold 201, and the sliding groove 2033 opened on the sliding rod is slidably connected to the anti-loosening bolt 209. One end of the anti-loosening bolt 209 is threadedly connected to the threaded hole opened in the rod groove 2013, which is convenient for stably installing the anti-loosening bolt 209 into the rod groove 2013. The anti-loosening bolt 209 is used to limit the sliding path of the sliding rod, so that the sliding rod can only slide smoothly up and down in the rod groove 2013. At the same time, the sliding rod is also used to limit the support member 203 to prevent the support member 203 from falling off the support mold 201 during the sliding process, ensuring their stable cooperation. In addition, the support member 203 is provided with the second ball 2031, and the arranged second ball 2031 is convenient for reducing the frictional force between the support member 203 and the channel steel formwork, so that when the channel steel formwork adjusts the cutting position during the feeding process, the channel steel formwork can slide smoothly on the support member 203, improving the convenience of feeding and debugging;

[0044] The telescopic strut 206 fixedly connected to the support member 203, the lower end of the telescopic strut 206 supports on the inner wall of the bottom of the placement cavity 2011, and the support spring 207 sleeved on the telescopic strut 206, the upper end of the support spring 207 abuts on the support member 203 and the lower end abuts on the inner wall of the bottom of the placement cavity 2011. The telescopic strut 206 and the support spring 207 are used to stably support the support member 203 on the support mold 201, ensuring their stable cooperation. At the same time, when the support member 203 is pressed by an external force, it can slide smoothly in the placement cavity 2011, ensuring that the channel steel formwork placed on the support member 203 can contact the upper part of the support mold 201, and the frictional resistance of the support mold 201 to the channel steel formwork is used for limit fixation to ensure stable use. Moreover, a support spring plate 208 is arranged between the lower part of the support member 203 and the bottom of the placement cavity 2011 to stably and effectively support the support member 203, ensuring the stable use of the support member 203. At the same time, it also ensures that the support member 203 can generate appropriate deformation during the up and down sliding process to avoid movement interference and ensure smooth use;

[0045] Among them, the first ball 2021 and the anti-slip strip 2025 are arranged on the die 202. When the channel steel template contacts the anti-slip strip 2025, it is convenient to increase the frictional resistance between the die 202 and the channel steel template, thereby ensuring that the support die 201 and the die 202 cooperate with each other to limit and fix the channel steel template well, so as to perform stable and effective cutting. The first ball 2021 is rotatably connected in the mounting seat 2022, and the mounting seat 2022 is slidably arranged in the moving cavity opened inside the inlay seat 2024. One end of the return spring 2023 arranged on the mounting seat 2022 abuts against the inner wall of the moving cavity inside the inlay seat 2024, and the inlay seat 2024 is fixedly inlaid in the inlay hole opened at the corresponding position on the die 202, which is convenient to stably install the first ball 2021 on the die 202, thereby reducing the frictional resistance between the channel steel template and the die 202, enabling the channel steel template to slide smoothly on the die 202. At the same time, when the die 202 is stressed and presses down on the channel steel template, the first ball 2021 is stressed. Under the action of stress, the first ball 2021 will drive the mounting seat 2022 to slide in the moving cavity inside the inlay seat 2024 and compress the return spring 2023, so that the first ball 2021 moves into the inlay seat 2024. At this time, the die 202 will contact the channel steel template, increasing the frictional resistance between the two, and performing stable and effective limit fixation on the channel steel template. Among them, when the die 202 presses down on the channel steel template, a downward pressure will be applied to the support member 203 through the channel steel template. The support member 203 is stressed and slides on the support die 201, and the channel steel template contacts the support die 201.

The connecting frame 5022 is slidably connected to the ear plates 5027. By using the cooperation between the two, the limiting frame 5021 is stably installed on the support frame 5026, so as to stably and effectively clamp and fix the channel steel formwork. At the same time, the limiting screw 5024 is used to limit and fix the limiting frame 5021, so that it is stably connected to the support frame 5026. And a driving rod 5025 is slidably inserted into the end of the limiting screw 5024 located below the bolt seat 5023. The driving rod 5025 is slidably connected to the insertion hole opened at the end of the limiting screw 5024.
