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

[0003] In this regard, China's patent application number: CN202410015460.5 discloses a fine cutting equipment for channel steel template processing, including an import die for guiding the inner and outer groove templates of the trapezoidal groove channel steel template as a whole, and two supporting dies are distributed in the template passing direction of the import die, one of which is fixed at a distance close to the import die, and the other supporting die is slidably arranged along the template passing direction of the import die; the sliding supporting die is equipped with a front block unloading mechanism for cutting and positioning the channel steel template before cutting and unloading the channel steel template after cutting, and the front block unloading mechanism is located on the side of the supporting die facing away from the import die; a cutting mechanism for channel steel template cutting is cooperated between the import die and the supporting die arranged nearby; the equipment provided by this invention is suitable for batch fixed-size cutting and forming processing, which improves the cutting production efficiency while ensuring the cutting accuracy and cutting quality.

[0004] The cutting equipment can position the template welding structure by setting a front-stop unloading mechanism, and can unload the cut template welding structure. However, during the unloading process of the template welding structure, the template welding structure will only contact one set of supporting molds, and the two ends of the template welding structure are suspended in the air. The two ends are unevenly affected by gravity, which will cause the template welding structure to tilt. The template welding structure will be stuck on the inner side of the supporting mold, making the unloading of the template welding structure not smooth, with large resistance, and easily damaging the device and workpiece.

[0005] Therefore, in order to solve the above problems, a fine cutting device for processing channel steel templates in construction projects is proposed. Summary of the Invention

[0006] The object of the present invention is to provide a fine cutting device for processing channel steel templates in construction engineering, so as to solve the problem in the prior art proposed in the above background technology.

However, during the unloading process of the welded structure of the template, the welded structure of the template will only contact a group of supporting molds, and the two ends of the welded structure of the template are suspended. The gravity acting on the two ends is uneven, which will cause the welded structure of the template to tilt.

[0011] Preferably, two sets of the fixing structures are provided, and the extending end of the electric telescopic rod is fixedly connected to the pressing die.

[0012] Preferably, a translation mechanism is installed on the top surface of the base, and the translation mechanism is used for the left and right movement of the fixed block on the top surface of the base.

[0013] Preferably, the fixed block is located on the left side of the lifting frame, one end of the coil spring is fixedly connected to the fixed block, the top surfaces of the support roller frame and the conveying roller are flush with the bottom surface of the die groove, and the first gear meshes with the second gear.

[0014] Preferably, two sets of the lower pressing roller frames are provided, and the two sets of the lower pressing roller frames are respectively located at the front and rear ends of the top surface of the fixed block, and the lower pressing roller frames are parallel to the support roller frame.

[0015] Preferably, both ends of the movable frame penetrate through the left side wall of the fixed block, the top surface of the rotating roller is lower than the top surface of the conveying roller, and one end of the first spring is fixedly connected to the inner wall of the movable groove.

[0016] Preferably, the clamping block cooperates with the movable block and the clamping groove, and one end of the second spring is fixedly connected to the movable block.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: By providing the lower pressing roller frame and the support roller frame, the cutting device of the present invention can support and limit the channel steel template on the upper and lower sides, so that when the channel steel template moves inside the fixed block, it can maintain a straight state, ensure the smoothness of unloading, and reduce the wear on the device and the workpiece, improving the use experience of the device.

[0018] A fixing structure, a discharging structure and a positioning structure are provided. The channel steel template to be cut is pushed between the two sets of die grooves and the material grooves, so that the left end of the channel steel template to be cut fits against the erected support roller frame, and the bottom surface of the left end of the channel steel template to be cut contacts the conveying roller. At this time, the clamping block is stuck on the left side of the movable block, which can fix and limit the erected state of the support roller frame. The electric telescopic rod is started to drive the pressing die to descend, and the pressing die moves downward close to the top surface of the channel steel template to be cut, so as to fix the channel steel template to be cut. Through the lifting frame and the cutting mechanism, the channel steel template can be cut and processed;

[0019] After being cut, the channel steel formwork is divided into left and right sections, and there is a certain gap between the two sections of the channel steel formwork. Since the right end of the left section of the channel steel formwork is suspended, the left section of the channel steel formwork will tilt slightly downward under the action of gravity. The support roller frame can limit the bottom surface of the left end of the left section of the channel steel formwork on the upper side, and can limit the tilting angle of the left section of the channel steel formwork, so that the left section of the channel steel formwork presses down on the rotating roller when tilting. The rotating roller drives the movable frame to move downward in the conveying roller and squeezes the first spring. When the movable frame moves, it drives the clamping block to descend on the left side of the movable block, so that the clamping block is aligned with the inside of the clamping groove left and right, and the fixing of the support roller frame on the left side of the fixed block can be released. At this time, pushing the right section of the channel steel formwork to the left can drive the left section of the channel steel formwork to move to the left together. The left section of the channel steel formwork moves to the left inside the fixed block under the action of the support roller frame, the rotating roller and the conveying roller;

[0020] The left section of the channel steel formwork pushes the support roller frame, so that the support roller frame deflects counterclockwise on the left side wall of the fixed block through the first rotating shaft. The movable block moves away from the outside of the clamping block. The support roller frame drives the first rotating shaft and the first sprocket to rotate. The first sprocket drives the second sprocket to rotate through the transmission chain. The second sprocket drives the first gear to rotate. The first gear drives the second gear to rotate. The second gear drives the pressing roller frame to deflect clockwise through the second rotating shaft, so that the support roller frame is horizontally located on the left side of the conveying roller, and the pressing roller frame presses on the top surface of the left section of the channel steel formwork;

[0021] When the length of the left section of the channel steel formwork exposed on the left side of the fixed block is greater than that on the right side, the left section of the channel steel formwork will tilt to the left under the action of gravity. Therefore, the left section of the channel steel formwork will increase on the left side of the fixed block, and the support roller frame supporting the left section of the channel steel formwork on the lower side. Therefore, the pressing roller frame will increase the pressure on the part of the left section of the channel steel formwork inside the chute. Since the pressing roller frame cannot continue to deflect clockwise and press down, the support roller frame cannot continue to deflect counterclockwise. Therefore, the support roller frame remains stationary in a horizontal state. The support roller frame and the pressing roller frame cooperate with each other, so that the channel steel formwork can remain straight inside the chute during unloading. The support roller frame, the pressing roller frame, the conveying roller and the rotating roller cooperate with each other, which can reduce the friction when the left section of the channel steel formwork moves inside the chute, making the unloading of the left section of the channel steel formwork smooth and stable;

[0022] When the right end of the left-section channel steel formwork is located on the support roller frame, start the support roller frame, and the left-section channel steel formwork can be conveyed to the left to unload the left-section channel steel formwork from the device. At the same time, the support roller frame loses the pressure of the left-section channel steel formwork, that is, it deflects clockwise and resets under the action of the first sprocket. Therefore, the pressing roller frame deflects counterclockwise and resets. After the left end of the right-section channel steel formwork moves onto the conveying roller, the downward pressure on the rotating roller can be released, and the movable frame and the rotating roller reset under the action of the first spring. At this time, the latch resets. Therefore, the movable block rotating around the circumference of the first spring is stuck outside the latch through the card slot, and the movable block can move on the mounting block, enabling the latch to smoothly pass through the card slot and cooperating with the second spring, so that the latch can be stuck on the left side of the movable block to realize the angle limit of the support roller frame for positioning the left end of the channel steel formwork next time.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] A fine cutting device for processing channel steel templates in construction engineering includes: a base 1, a lifting frame 11 is installed on the top surface of the base 1, and a cutting mechanism 12 is installed on the lifting frame 11;

[0036] A fixing structure 2 is installed on the top surface of the base 1. The fixing structure 2 includes a support mold 21. The support mold 21 is fixedly installed on the top surface of the base 1. A mold groove 22 is opened on the top surface of the support mold 21. A bracket 23 is fixedly welded on the top surface of the support mold 21. A pressing mold 24 is slidably installed inside the mold groove 22. An electric telescopic rod 25 is fixedly installed on the top surface of the bracket 23. The mold groove 22 cooperates with the pressing mold 24 to support and fix the channel steel template to be cut to ensure the stability during cutting.

[0037] Furthermore, a discharging structure 3 is installed on the top surface of the base 1. The discharging structure 3 includes a fixed block 31 which is slidably installed on the top surface of the base 1. A material groove 32 is formed on the top surface of the fixed block 31. A first rotating shaft 33 is movably installed on the left side wall of the fixed block 31 through a bearing. One end of the first rotating shaft 33 is fixedly connected with a first sprocket 34. A torsion spring 35 is fixedly connected to the outer wall of the first rotating shaft 33. The other end of the first rotating shaft 33 is fixedly connected with a support roller frame 36. A first gear 37 is movably installed on the front and rear walls of the fixed block 31 through a bearing. A second sprocket 38 is welded on the surface of the first gear 37. A transmission chain 39 is sleeved outside the first sprocket 34 and the second sprocket 38. A second rotating shaft 310 is movably installed on the top surface of the fixed block 31 through a bearing. One end of the second rotating shaft 310 is fixedly connected with a second gear 311. The other end of the second rotating shaft 310 is fixedly connected with a pressing roller frame 312. An activity groove 313 is formed on the right side wall of the fixed block 31. A conveying roller 314 is movably installed on the bottom surface of the material groove 32 through a bearing. The pressing roller frame 312 and the support roller frame 36 cooperate with each other to support and limit the channel steel formwork on the upper and lower sides, so that when the channel steel formwork moves inside the fixed block 31, it can maintain a straight state, ensuring the smoothness of discharging, reducing the wear of the device and the workpiece, and improving the use experience of the device.

[0038] Furthermore, a positioning structure 4 is installed on the discharging structure 3. The positioning structure 4 includes a movable frame 41 which is slidably installed inside the activity groove 313. A rotating roller 42 is movably installed on the top surface of the movable frame 41 through a bearing. A first spring 43 is fixedly connected to the bottom surface of the movable frame 41. Clamping blocks 44 are integrally formed at both ends of the movable frame 41. Mounting blocks 45 are fixedly installed on the front and rear walls of the support roller frame 36. Second springs 46 are fixedly connected to both ends of the mounting blocks 45. Movable blocks 47 are slidably installed outside the mounting blocks 45. A clamping groove 48 is formed on the surface of the movable blocks 47. Through the cooperation between the clamping blocks 44, the movable blocks 47 and the clamping groove 48, the support roller frame 36 can be fixed in a vertical state on the left side of the fixed block 31, capable of shielding the left side of the material groove 32 to position the left end position of the channel steel formwork to determine the cutting length of the channel steel formwork, and the movable blocks 47 can move on the support roller frame 36. When the support roller frame 36 resets, the movable blocks 47 can move relative to the clamping blocks 44 so that the clamping blocks 44 can smoothly pass through the clamping groove 48.

[0039] Furthermore, there are two groups of fixing structures 2. The extending end of the electric telescopic rod 25 is fixedly connected with the pressing die 24. The electric telescopic rod 25 provides power for the lifting movement of the pressing die 24 inside the die groove 22.

[0040] Furthermore, a translation mechanism is installed on the top surface of the base 1. The translation mechanism is used to move the fixing block 31 left and right on the top surface of the base 1. Before processing, the fixing block 31 is moved through the translation mechanism to adjust the distance between the support roller frame 36 and the cutting mechanism 12 according to the required cutting length dimension.

[0041] Furthermore, the fixing block 31 is located on the left side of the lifting frame 11. One end of the coil spring 35 is fixedly connected to the fixing block 31. The top surfaces of the support roller frame 36 and the conveying roller 314 are flush with the bottom surface of the die groove 22. The first gear 37 meshes with the second gear 311. The fixing block 31 can support the channel steel formwork on the left side. The coil spring 35 provides power for the support roller frame 36 to reset to a vertical state on the left side wall of the fixing block 31. The channel steel formwork is placed horizontally on the top surfaces of the support roller frame 36, the conveying roller 314 and the die groove 22. The rotation of the first gear 37 can drive the second rotating shaft 310 to rotate through the second gear 311.

[0042] Furthermore, two groups of pressing roller frames 312 are provided. The two groups of pressing roller frames 312 are respectively located at the front and rear ends of the top surface of the fixing block 31. The pressing roller frames 312 are parallel to the support roller frame 36. The two groups of pressing roller frames 312 can press and fix the top surface of the channel steel formwork in the material groove 32 on the front and rear sides. The deflection angles of the pressing roller frames 312 and the support roller frame 36 are always the same. When the support roller frame 36 supports the bottom surface of the channel steel formwork, the pressing roller frames 312 can press on the top surface of the channel steel formwork.

[0043] Furthermore, both ends of the movable frame 41 penetrate through the left side wall of the fixing block 31. The top surface of the rotating roller 42 is lower than the top surface of the conveying roller 314. One end of the first spring 43 is fixedly connected to the inner wall of the movable groove 313. When the channel steel formwork is placed on the die groove 22 and the conveying roller 314, the rotating roller 42 does not contact the bottom surface of the channel steel formwork. When the channel steel formwork is cut and the left section is only located on the conveying roller 314, the channel steel formwork can be inclined to contact the rotating roller 42, so that after the channel steel formwork is cut, the support roller frame 36 can move, facilitating the removal of the channel steel formwork from the left side.

[0044] Furthermore, the clamping block 44 cooperates with the movable block 47 and the clamping groove 48. One end of the second spring 46 is fixedly connected to the movable block 47. The clamping block 44 can be stuck to the left side of the movable block 47 via the clamping groove 48. The movable block 47 can move on the mounting block 45. The second spring 46 provides power for the movable block 47 to reset and center on the mounting block 45.

[0045] Working principle: Before processing, move the fixed block 31 through the translation mechanism to adjust the distance between the support roller frame 36 and the cutting mechanism 12 according to the required cutting length dimension. During processing, push the channel steel template to be cut between the two groups of die slots 22 and the material slot 32, so that the left end of the channel steel template to be cut fits against the erected support roller frame 36, and the bottom surface of the left end of the channel steel template to be cut contacts the conveying roller 314. At this time, the clamping block 44 is stuck on the left side of the movable block 47, which can fix and limit the erected state of the support roller frame 36. Start the electric telescopic rod 25 to drive the pressing die 24 to descend. The pressing die 24 moves downward close to the top surface of the channel steel template to be cut, and the channel steel template to be cut can be fixed. Through the lifting frame 11 and the cutting mechanism 12, the channel steel template can be cut and processed;

[0046] After being cut, the channel steel template is divided into left and right sections, and there is a certain interval between the two sections of the channel steel template. Since the right end of the left section of the channel steel template is suspended, the left section of the channel steel template will slightly tilt downward under the action of gravity. And the support roller frame 36 can limit the bottom surface of the left end of the left section of the channel steel template on the upper side, which can limit the tilting angle of the left section of the channel steel template, so that the left section of the channel steel template presses down the rotating roller 42 when tilting. The rotating roller 42 drives the movable frame 41 to move downward in the conveying roller 314 and squeeze the first spring 43. When the movable frame 41 moves, it drives the clamping block 44 to descend on the left side of the movable block 47, so that the clamping block 44 is aligned with the inside of the card slot 48 left and right, and the fixation of the support roller frame 36 on the left side of the fixed block 31 can be released. At this time, push the right section of the channel steel template to the left, which can drive the left section of the channel steel template to move to the left together. The left section of the channel steel template moves to the left inside the fixed block 31 under the action of the support roller frame 36, the rotating roller 42 and the conveying roller 314;

[0047] The left section of the channel steel template pushes the support roller frame 36, so that the support roller frame 36 rotates counterclockwise on the left side wall of the fixed block 31 through the first rotating shaft 33. The movable block 47 moves away from the outside of the clamping block 44. The support roller frame 36 drives the first rotating shaft 33 and the first sprocket 34 to rotate. The first sprocket 34 drives the second sprocket 38 to rotate through the transmission chain 39. The second sprocket 38 drives the first gear 37 to rotate. The first gear 37 drives the second gear 311 to rotate. The second gear 311 drives the pressing roller frame 312 to rotate clockwise through the second rotating shaft 310, so that the support roller frame 36 is horizontally located on the left side of the conveying roller 314, and the pressing roller frame 312 presses on the top surface of the left section of the channel steel template;

[0048] When the length of the left-section channel steel formwork exposed on the left side of the fixed block 31 is greater than that on the right side, the left-section channel steel formwork will tilt to the left under the action of gravity. Therefore, the left-section channel steel formwork will increase the support roller frame 36 located on the left side of the fixed block 31 and supporting the left-section channel steel formwork on the lower side. Therefore, the pressing roller frame 312 will increase the pressure on the part of the left-section channel steel formwork inside the material chute 32. Since the pressing roller frame 312 cannot continue to deflect clockwise and press down, the support roller frame 36 cannot continue to deflect counterclockwise. Therefore, the support roller frame 36 remains stationary in a horizontal state. The support roller frame 36 and the pressing roller frame 312 cooperate with each other, enabling the channel steel formwork to remain straight inside the material chute 32 during unloading. The support roller frame 36, the pressing roller frame 312, the conveying roller 314, and the rotating roller 42 cooperate with each other, reducing the friction when the left-section channel steel formwork moves inside the material chute 32, making the unloading of the left-section channel steel formwork smooth and stable.

[0049] When the right end of the left-section channel steel formwork is located on the support roller frame 36, start the support roller frame 36 to convey the left-section channel steel formwork to the left to unload the left-section channel steel formwork from the device. At the same time, the support roller frame 36 loses the pressure of the left-section channel steel formwork and deflects clockwise to reset under the action of the first sprocket 34. Therefore, the pressing roller frame 312 deflects counterclockwise to reset. After the left end of the right-section channel steel formwork moves onto the conveying roller 314, the downward pressure on the rotating roller 42 can be released. The movable frame 41 and the rotating roller 42 reset under the action of the first spring 43. At this time, the latch 44 resets. Therefore, the movable block 47 rotating around the circumference of the first spring 43 is stuck outside the latch 44 through the card slot 48. And the movable block 47 can move on the mounting block 45, enabling the latch 44 to smoothly pass through the card slot 48. Cooperating with the second spring 46, the latch 44 can be stuck on the left side of the movable block 47 to limit the angle of the support roller frame 36 for positioning the left end of the channel steel formwork next time.

[0050] The above is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Any ordinary technician in the industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and described above. However, any equivalent changes such as slight modifications, decorations, and evolutions made by those skilled in the art within the scope of the technical solution of the present invention using the technical content disclosed above are equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
