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 introduction mold for guiding the inner and outer groove templates of a trapezoidal groove channel steel template as a whole, and two supporting molds are distributed in the template passing direction of the introduction mold, one of which is fixed at a position close to the introduction mold, and the other supporting mold is slidably arranged along the template passing direction of the introduction mold; the sliding supporting mold 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 mold facing away from the introduction mold; a cutting mechanism for cutting the channel steel template is cooperated between the introduction mold and the supporting mold arranged closely; the equipment provided by the invention is suitable for batch sizing 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 template welding structure after cutting. However, during the unloading process of the template welding structure, the template welding structure will only contact with 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 great 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 formwork in construction engineering is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a fine cutting equipment for processing channel steel formworks in construction projects, so as to solve the problem that the cutting equipment in the prior art proposed in the above background technology can position the formwork welding structure by setting a front stop unloading mechanism, and can unload the cut formwork welding structure, but during the unloading process of the formwork welding structure, the formwork welding structure will only contact with one set of supporting molds, and the two ends of the formwork welding structure are suspended in the air, and the two ends are unevenly affected by gravity, which will cause the formwork welding structure to tilt, and the formwork welding structure will be stuck on the inner side of the supporting mold, so that the unloading of the formwork welding structure is not smooth, there is a large resistance, and it is easy to damage the device and the workpiece.

[0011] Preferably, the fixing structure is provided with two groups, and the extended end of the electric telescopic rod is fixedly connected to the 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 fixing 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 surface of the supporting roller frame and the conveying roller are flush with the bottom surface of the mold groove, and the first gear is meshed with the second gear.

[0014] Preferably, two groups of the lower pressing roller frames are provided, and the two groups 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 supporting roller frames.

[0015] Preferably, both ends of the movable frame pass 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 slot, 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: the cutting equipment of the present invention can support and limit the channel steel template on the upper and lower sides by setting a lower pressure roller frame and a supporting roller frame, so that the channel steel template can maintain a straight state when it moves inside the fixed block, thereby ensuring the smoothness of unloading, reducing the wear on the device and the workpiece, and improving the user experience of the device.

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

[0019] After being cut, the channel steel template is divided into two 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 tilt slightly downward under the action of gravity, and the supporting roller frame 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 when tilting, and 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 card block to descend on the left side of the movable block, so that the card block is aligned with the inside of the card slot on the left and right, and the support roller frame can be released from the left side of the fixed block. At this time, the right section of the channel steel template is pushed 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 under the action of the supporting roller frame, the rotating roller and the conveying roller;

[0020] The left section channel steel template pushes the supporting roller frame, so that the supporting 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 supporting 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 lower pressure roller frame to deflect clockwise through the second rotating shaft, so that the supporting roller frame is horizontally located on the left side of the conveying roller, and the lower pressure roller frame is pressed on the top surface of the left section channel steel template;

[0021] When the length of the left section of the channel steel template exposed on the left side of the fixed block is greater than the length on the right side, the left section of the channel steel template will tilt to the left under the action of gravity, so the left section of the channel steel template will increase the support roller frame located on the left side of the fixed block and supporting the left section of the channel steel template at the bottom, so the lower pressure roller frame will increase the pressure on the inner part of the left section of the channel steel template located at the material trough, and the lower pressure roller frame cannot continue to deflect and press clockwise, so the support roller frame cannot continue to deflect counterclockwise, so the support roller frame remains horizontal and motionless, the support roller frame and the lower pressure roller frame cooperate with each other, which can keep the channel steel template in a straight state inside the material trough during unloading, the support roller frame, the lower pressure roller frame, the conveying roller and the rotating roller cooperate with each other, which can reduce the friction of the left section of the channel steel template when it moves inside the material trough, so that the unloading of the left section of the channel steel template is smooth and stable;

[0022] When the right end of the left section channel steel template is located on the supporting roller frame, the supporting roller frame is started to transport the left section channel steel template to the left to remove the left section channel steel template from the device. At the same time, the supporting roller frame loses the pressure of the left section channel steel template, that is, it deflects and resets clockwise under the action of the first sprocket. Therefore, the downward pressure roller frame deflects and resets counterclockwise, and the left end of the right section channel steel template can release the downward pressure on the rotating roller after moving to the conveying roller. The movable frame and the rotating roller are reset under the action of the first spring. At this time, the block is reset, so the movable block rotating around the circumference of the first spring is clamped on the outside of the block through the clamping groove, and the movable block can move on the mounting block, so that the block can pass through the clamping groove smoothly, and cooperate with the second spring to make the block clamped on the left side of the movable block, thereby limiting the angle of the supporting roller frame, so as to position the left end of the channel steel template next time.

[0038] Further, a positioning structure 4 is installed on the unloading structure 3, and the positioning structure 4 includes a movable frame 41, which is slidably installed on the inner side of the movable groove 313, and a rotating roller 42 is movably installed on the top surface of the movable frame 41 through a bearing, and a first spring 43 is fixedly connected to the bottom surface of the movable frame 41, and a clamping block 44 is integrally formed at both ends of the movable frame 41, and a mounting block 45 is fixedly installed on the front and rear walls of the supporting roller frame 36, and a second spring 46 is fixedly connected to both ends of the mounting block 45, and a movable block 45 is slidably installed on the outer side of the mounting block 45. 47, a slot 48 is provided on the surface of the movable block 47, and through the cooperation among the block 44, the movable block 47 and the slot 48, the support roller frame 36 can be fixed in a vertical state on the left side of the fixed block 31, and can be blocked on the left side of the material trough 32 to locate the left end of the channel steel template to determine the cutting length of the channel steel template, and the movable block 47 can move on the support roller frame 36. When the support roller frame 36 is reset, the movable block 47 can move relative to the block 44, so that the block 44 can smoothly pass through the slot 48.

[0039] Furthermore, the fixed structure 2 is provided with two groups, and the extended end of the electric telescopic rod 25 is fixedly connected to the die 24 , and the electric telescopic rod 25 provides power for the lifting and lowering activities of the die 24 inside the die groove 22 .

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

[0041] Furthermore, the fixed 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 fixed block 31, the top surface of the supporting roller frame 36 and the conveying roller 314 are flush with the bottom surface of the mold groove 22, the first gear 37 is engaged with the second gear 311, and the fixed block 31 can support the channel steel template on the left side. The coil spring 35 provides power for the supporting roller frame 36 to reset to a vertical state on the left side wall of the fixed block 31. The channel steel template is placed horizontally on the supporting roller frame 36, the conveying roller 314 and the top surface of the mold 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, and the two groups of pressing roller frames 312 are respectively located at the front and rear ends of the top surface of the fixed block 31. The pressing roller frames 312 and the supporting roller frames 36 are parallel to each other. The two groups of pressing roller frames 312 can press down and fix the top surface of the channel steel template in the material trough 32 on the front and rear sides. The deflection angles of the pressing roller frames 312 and the supporting roller frames 36 are always consistent. When the supporting roller frames 36 are supported on the bottom surface of the channel steel template, the pressing roller frames 312 can be pressed on the top surface of the channel steel template.

[0043] Furthermore, both ends of the movable frame 41 pass through the left side wall of the fixed block 31, the top surface of the rotating roller 42 is lower than the top surface of the conveying roller 314, and one end of the first spring 43 is fixedly connected to the inner wall of the movable groove 313. When the channel steel template is placed on the mold groove 22 and the conveying roller 314, the rotating roller 42 does not contact the bottom surface of the channel steel template. When the channel steel template is cut and the left section is only located on the conveying roller 314, the channel steel template can be tilted to contact the rotating roller 42, so that after the channel steel template is cut, the supporting roller frame 36 can be movable, which is convenient for removing the channel steel template from the left side.

[0044] Furthermore, the clamping block 44 cooperates with the movable block 47 and the clamping slot 48, one end of the second spring 46 is fixedly connected to the movable block 47, the clamping block 44 can be clamped on the left side of the movable block 47 through the clamping slot 48, the movable block 47 can be movable on the mounting block 45, and the second spring 46 provides power for the movable block 47 to be reset to the center on the mounting block 45.

[0045] Working principle: Before processing, the fixed block 31 is moved by the translation mechanism to adjust the distance between the support roller frame 36 and the cutting mechanism 12 according to the required cutting length. During processing, the channel steel template to be cut is pushed between the two sets of die grooves 22 and the material groove 32, so that the left end of the channel steel template to be cut fits with the erected support roller frame 36, and the bottom surface of the left end of the channel steel template to be cut contacts with the conveying roller 314. At this time, the clamping block 44 is stuck on the left side of the movable block 47, and the erected state of the support roller frame 36 can be fixed and limited. The electric telescopic rod 25 is started to drive the die 24 to descend, and the die 24 moves downward close to the top surface of the channel steel template to be cut, so that the channel steel template to be cut can be fixed. The channel steel template can be cut by the lifting frame 11 and the cutting mechanism 12.

[0046] After being cut, the channel steel template is divided into two 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 tilt slightly 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, and 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 is active, it drives the block 44 to descend on the left side of the movable block 47, so that the block 44 is aligned with the inside of the card slot 48 on the left and right, and the support roller frame 36 can be released from the fixation of the left side of the fixed block 31. At this time, pushing the right section of the channel steel template to the left 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 channel steel template pushes the support roller frame 36, so that the support roller frame 36 deflects counterclockwise on the left side wall of the fixed block 31 through the first rotating shaft 33, and the movable block 47 moves away from the outside of the clamping block 44, and the support roller frame 36 drives the first rotating shaft 33 and the first sprocket 34 to rotate, and the first sprocket 34 drives the second sprocket 38 to rotate through the transmission chain 39, and the second sprocket 38 drives the first gear 37 to rotate, and the first gear 37 drives the second gear 311 to rotate, and the second gear 311 drives the lower pressure roller frame 312 to deflect 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 lower pressure roller frame 312 is pressed on the top surface of the left section channel steel template;

[0048] When the length of the left section channel steel template exposed on the left side of the fixed block 31 is greater than the length on the right side, the left section channel steel template will tilt to the left under the action of gravity, so the left section channel steel template will increase the support roller frame 36 located on the left side of the fixed block 31, and supporting the left section channel steel template at the bottom, so the lower pressure roller frame 312 will increase the pressure on the inner part of the left section channel steel template located at the material trough 32, and the lower pressure roller frame 312 cannot continue to deflect and press clockwise, so the support roller frame 36 cannot continue to deflect counterclockwise, so the support roller frame 36 remains in a horizontal state and does not move, the support roller frame 36 and the lower pressure roller frame 312 cooperate with each other, so that the channel steel template can be kept in a straight state inside the material trough 32 during unloading, and the support roller frame 36, the lower pressure roller frame 312, the conveying roller 314 and the rotating roller 42 cooperate with each other, which can reduce the friction force of the left section channel steel template when it moves inside the material trough 32, so that the unloading of the left section channel steel template is smooth and stable;

[0049] When the right end of the left channel steel template is located on the supporting roller frame 36, the supporting roller frame 36 is started to convey the left channel steel template to the left, so as to remove the left channel steel template from the device. At the same time, the supporting roller frame 36 loses the pressure of the left channel steel template, that is, it deflects and resets clockwise under the action of the first sprocket 34, so the pressing roller frame 312 deflects and resets counterclockwise, and the left end of the right channel steel template can release the downward pressure on the rotating roller 42 after moving onto the conveying roller 314, and the movable frame 41 and the rotating roller 42 are moved. The rotating roller 42 is reset under the action of the first spring 43, and the clamping block 44 is reset at this time. Therefore, the movable block 47 rotating around the circumference of the first spring 43 is clamped on the outside of the clamping block 44 through the clamping groove 48, and the movable block 47 can move on the mounting block 45, so that the clamping block 44 can smoothly pass through the clamping groove 48, and cooperate with the second spring 46, so that the clamping block 44 can be clamped on the left side of the movable block 47, realizing the limiting of the angle of the supporting roller frame 36, so as to position the left end of the channel steel template next time.

Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention.
