Description

Technical Field

[0001] The invention belongs to the technical field of steel structure cutting, in particular to an automatic steel structure cutting machine. Background Art

[0002] Steel structure cutting is a processing technology that uses a mixture of industrial gas and oxygen to generate high temperatures to melt, blow off slag and split steel. It is mainly used in the processing and manufacturing of steel structure components. Its main technologies include flame cutting, water cutting, plasma cutting, etc. Among them, flame cutting has become the mainstream process due to its low cost and convenient operation.

[0003] A patent with publication number CN118682312A discloses a steel structure cutting device and processing method, including a body, a drive mechanism, a mounting base and a laser head assembly installed at the bottom of the mounting base. The body is connected to the mounting base through the drive mechanism. A conical reflective sleeve is provided under the laser head assembly. An annular plate is installed at the bottom of the conical reflective sleeve. A plurality of arc grooves are provided at the bottom of the annular plate, and a group of conical grooves are provided at the bottom of each arc groove.

[0004] In the current existing technology, when cutting existing steel structures, some channel steels, I-beams or steel structures of other shapes are cut. However, these steel structures are relatively heavy, and multiple employees are required to lift the steel structures and fix the steel structures. However, after cutting the steel structures, employees are required to dismantle and move the steel structures. This leads to the fact that in order to ensure the integrity of the cutting of the steel structures, the steel structures will be placed horizontally on the surface of the cutting table. When one end of the steel structure is cut, the horizontality of the steel structure will be affected, so that after the employees remove the fixing device, the heavier end will be removed due to the removal of the fixing device, causing the steel structure to fall down, which is easy to cause harm to the employees who dismantle the device, and the steel structure cannot be fixed, cut, or peeled off independently.

[0005] To this end, the present invention provides an automatic steel structure cutting machine. Summary of the Invention

[0008] Preferably, a guiding inclined groove is provided at the top entrance of the steel structure limiting arm plate, and a hydraulic rod is fixedly installed on the bottom surface of the lifting pad.

[0009] Preferably, a metal cutting table is fixedly mounted on the bottom surface of the hydraulic rod, and a motor 1 is fixedly mounted on the inner wall surface of the metal cutting table.

[0010] Preferably, a cutting blade is fixedly connected to the output end of the motor 1, and a chip collection box is provided on the bottom surface of the metal cutting table.

[0011] Preferably, the bottom surface of the steel structure limiting arm plate is movably overlapped on the surface of the supporting limiting plate, and the bottom surface of the steel structure limiting arm plate is horizontally overlapped on the outer surface of the overlapping supporting plate.

[0012] Preferably, two side surfaces of the steel structure limit arm plate are provided with empty grooves, an extrusion slider is movably sleeved on the inner side wall of the empty groove, and two side surfaces of the extrusion slider are provided with oblique grooves.

[0013] Preferably, an extrusion cavity is provided in the middle of the inclined groove, and the outer surface of the inclined groove is movably overlapped with the outer surface of the steel structure.

[0014] Preferably, a notch is provided on the bottom surface of the limiting support plate, and motor 2 is fixedly installed on the outer surface of the limiting support plate and at both side edges of the notch, and a rotating disk is fixedly connected to the output end of motor 2.

[0015] Preferably, an extrusion push rod is fixedly connected to the outer surface of the rotating disk and located at one side edge position, and a swing arm plate is swingably connected to the bottom edge position of the notch.

[0016] Preferably, a triangular limiting plate is provided on the bottom edge of the swing arm plate, and the outer surface of the triangular limiting plate is movably overlapped on the bottom outer surface of the steel structure.

[0017] The beneficial effects of the present invention are as follows: 1. The automatic steel structure cutting machine described in the present invention clamps the steel structure into the interior of the limit support plate and drops it under its own gravity, so that the steel structure contacts and presses down the raised end of the steel structure limit arm plate, and causes the steel structure limit arm plate to swing. After the swing, the surface of the steel structure limit arm plate is bonded to the bottom surface of the steel structure, and the steel structure limit arm plate is used to limit and fix the position of the steel structure. At the same time, the overlap support plate is used to horizontally overlap the steel structure limit arm plates together to maintain the horizontal angle of the steel structure. 2. The automatic steel structure cutting machine described in the present invention, when the steel structure is defined, cooperates with the cutting knife to cut the surface of the steel structure into two sections, at this time, the gravity of the tail end of the steel structure is used to drive the steel structure limit arm plate to swing downward on the surface of the lifting pad. The swinging steel structure limit arm plate will form a 50° inclination angle under the limitation of the supporting limit plate. At this time, the steel structure inside the steel structure limit arm plate will be clamped by the inclination angle and squeezed by the weight of the steel structure itself, so that the steel structure slides off the surface of the steel structure limit arm plate; 3. The automatic steel structure cutting machine described in the present invention, as the steel structure is clamped into the interior of the steel structure limit arm plate, the steel structure will squeeze and push the extrusion slider inside the empty slot, and under the guidance of the inclined slot, the extrusion slider is squeezed and pushed out. As the steel structure limit arm plate is gradually squeezed to form a horizontal angle, the inclined slot on the outer surface of the extrusion slider will slide and press on the top surface of the lifting pad. As the extrusion slider continues to squeeze, the extrusion cavity is compressed, and at the same time, the surface of the extrusion slider is tightly attached to the outer surface of the steel structure, thereby increasing the friction and anti-slip effect between the extrusion slider and the steel structure. 4. The automatic steel structure cutting machine described in the present invention has the following advantages: when the steel structure is clamped and fixed inside the steel structure limit arm plate, the lifting pad is lowered by the hydraulic rod, and the pair of cutting knives are started by the motor. As the steel structure comes into contact with the cutting knives under the traction of the lifting pad, the steel structure is cut. The broken steel structure will be guided by the steel structure limit arm plate to tilt to both sides, and then the broken steel structure will be separated from the surface of the steel structure limit arm plate, eliminating the need for employees to perform secondary disassembly and transportation of the cut steel structure later; 5. The automatic steel structure cutting machine of the present invention, when the steel structure is placed in the middle position of the two limit support plates, cooperates with the two pairs of rotating disks of the motor to rotate, and causes the extrusion push rods on the outer surface of the rotating disk to press against the outer surface of the swing arm plate. At this time, the triangular limit plates on the outer bottom surface of the swing arm plate are clamped and limited to the bottom corner position of the steel structure. The interlaced force between the triangular limit plates and the surface of the steel structure is used to firmly limit the steel structure inside the limit support plates; 6. The automatic cutting machine for steel structures described in the present invention, after the steel structure is cut by the cutting knife, cooperates with the motor to rotate the two pairs of extrusion push rods, and utilizes the deviation of the position of the extrusion push rods on the surface of the rotating disk, so that the extrusion push rods will produce a gap drop during the rotation process, and then the triangular limit plate will swing the swing arm plate to both sides under the pressure of the steel structure, and the swing arm plate will enter the gap between the rotating disk and the extrusion push rod, so that the steel structure will fall under the limitation of the limit support plate, and be clamped into the interior of the steel structure limit arm plate.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 8 As shown, an automatic cutting machine for steel structures in an embodiment of the present invention includes a lifting pad 114 and a steel structure 12 movably sleeved on the outer surface of the top of the lifting pad 114, two groups of overlapping support plates 115 are fixedly connected to the top surface of the lifting pad 114 and located at the edge positions on both sides, and a support limit plate 116 is provided on one side surface of the overlapping support plate 115, and steel structure limiting arm plates 117 are swingably connected to the top two side surfaces of the lifting pad 114 and located at the top edge position of the overlapping support plate 115, the outer surface of the steel structure 12 is movably sleeved on the inner wall surface of the steel structure limiting arm plate 117, and a clamping support frame 13 is detachably installed on the top surface of the lifting pad 114 and located at the edge positions on both sides of the steel structure limiting arm plate 117, a limiting support plate 131 is fixedly installed on the top surface of the clamping support frame 13, and the inner wall surface of the limiting support plate 131 is movably overlapped on the outer surface of the steel structure 12.

[0023] Cooperate with the staff to clamp the steel structure 12 into the interior of the limit support plate 131, and let the steel structure 12 fall under its own gravity, cooperate with the steel structure 12 to press down the raised end of the steel structure limit arm plate 117, and make the steel structure limit arm plate 117 swing, so that the fallen end of the steel structure limit arm plate 117 is fitted with the bottom surface of the steel structure 12, and use the steel structure limit arm plate 117 to limit and fix the position of the steel structure 12, as shown in the figure. Figure 4 As shown, the steel structure limit arm plates 117 are horizontally overlapped together by using the overlap support plates 115 to maintain the horizontal angle of the steel structure 12; When the steel structure 12 is defined, the surface of the steel structure 12 is cut into two sections with the help of a cutting knife. At this time, the gravity of the tail end of the steel structure 12 is used to drive the steel structure limit arm plate 117 to swing downward on the surface of the lifting pad 114. Figure 3As shown, the swinging steel structure limit arm plate 117 will form a 50° inclination angle under the limitation of the support limit plate 116. At this time, the steel structure 12 inside the steel structure limit arm plate 117 will be clamped by the inclination angle and squeezed by the weight of the steel structure 12 itself, so that the steel structure 12 will slide off the surface of the steel structure limit arm plate 117.

[0024] like Figure 1-Figure 4 and Figures 7 and 8 As shown, a guiding inclined groove 118 is provided at the top entrance of the steel structure limiting arm plate 117, a hydraulic rod 111 is fixedly installed on the bottom surface of the lifting pad 114, and an empty groove a1 is provided on the two side surfaces of the steel structure limiting arm plate 117. An extrusion slider a2 is movably connected to the inner wall surface of the empty groove a1, and an inclined groove a3 is provided on the two side surfaces of the extrusion slider a2. An extrusion cavity a4 is provided in the middle position of the inclined groove a3, and the outer surface of the inclined groove a3 is movably overlapped on the outer surface of the steel structure 12.

[0025] When the steel structure 12 falls, the bottom surface of the steel structure 12 will first contact the inner wall surface of the raised end of the steel structure limit arm plate 117, and under the continuous downward pressure of the steel structure 12, the steel structure limit arm plate 117 will swing. At this time, the guide inclined groove 118 on the top surface of the steel structure limit arm plate 117 will pull the falling steel structure 12 in position, so that the steel structure 12 can be effectively clamped into the interior of the steel structure limit arm plate 117. After the steel structure 12 is clamped into the interior of the steel structure limiting arm plate 117, the steel structure 12 will squeeze and push the extrusion slider a2 inside the empty slot a1, and squeeze and push the extrusion slider a2 out under the guidance of the inclined groove a3. As the steel structure limiting arm plate 117 is gradually squeezed to form a horizontal angle, the inclined groove a3 on the outer surface of the extrusion slider a2 will slide and press on the top surface of the lifting pad 114. As the extrusion slider a2 continues to squeeze, the extrusion cavity a4 is compressed, and at the same time, the surface of the extrusion slider a2 is tightly fitted to the outer surface of the steel structure 12, thereby increasing the friction and anti-slip effect between the extrusion slider a2 and the steel structure 12. After the steel structure 12 is cut, the steel structure 12 gradually slides down from the surface of the steel structure limiting arm plate 117 by utilizing the fact that the gravity of the steel structure 12 itself is greater than the friction force of the extrusion slider a2 and under the traction of the inclined angle of the support limit plate 116, the steel structure 12 is detached from the surface of the steel structure limiting arm plate 117.

[0026] like Figures 1 to 4 and Figure 7-Figure 8As shown, a metal cutting table 11 is fixedly mounted on the bottom surface of the hydraulic rod 111, a motor 112 is fixedly mounted on the inner wall surface of the metal cutting table 11, a cutting knife 113 is fixedly connected to the output end of the motor 112, a chip collection box 119 is provided on the bottom surface of the metal cutting table 11, the bottom surface of the steel structure limiting arm plate 117 is movably overlapped on the surface of the supporting limiting plate 116, and the bottom surface of the steel structure limiting arm plate 117 is horizontally overlapped on the outer surface of the overlapping support plate 115.

[0027] When the steel structure 12 is clamped and fixed inside the steel structure limiting arm plate 117, the lifting pad 114 is lowered by the hydraulic rod 111, and the cutting knife 113 is started by the motor 112. As the steel structure 12 contacts the cutting knife 113 under the traction of the lifting pad 114, the steel structure 12 is cut. The broken steel structure 12 will be tilted to both sides under the guidance of the steel structure limiting arm plate 117, and then the broken steel structure 12 will be detached from the surface of the steel structure limiting arm plate 117, so that the cut steel structure 12 does not need to be disassembled and transported by employees at a later time.

[0028] like Figures 5 and 6 As shown, a notch is provided on the bottom surface of the limiting support plate 131, and a motor 2 134 is fixedly installed on the outer surface of the limiting support plate 131 and at the edge positions on both sides of the notch, a rotating disk 135 is fixedly connected to the output end of the motor 2 134, and an extrusion push rod 136 is fixedly connected to the outer surface of the rotating disk 135 and at the edge position of one side, a swing arm plate 132 is swingably connected to the bottom edge position of the notch, a triangular limiting plate 133 is provided on the bottom edge position of the swing arm plate 132, and the outer surface of the triangular limiting plate 133 is movably overlapped on the bottom outer surface of the steel structure 12.

[0029] When the steel structure 12 is placed in the middle of the two limit support plates 131, the second motor 134 is used to rotate the rotating disk 135, so that the extrusion push rod 136 on the outer surface of the rotating disk 135 is pressed against the outer surface of the swing arm plate 132. At this time, the triangular limit plate 133 on the outer bottom surface of the swing arm plate 132 is clamped and limited to the bottom corner position of the steel structure 12. The interlaced force between the triangular limit plate 133 and the surface of the steel structure 12 is used to firmly limit the steel structure 12 inside the limit support plate 131. After the current steel structure 12 is cut by the cutting knife 113, the extrusion push rod 136 is rotated in conjunction with the motor 2 134, and the deviation of the extrusion push rod 136 on the surface position of the rotating disk 135 is used to make the extrusion push rod 136 produce a gap drop during the rotation process, so that the triangular limit plate 133 swings the swing arm plate 132 to both sides under the pressure of the steel structure 12, and makes the swing arm plate 132 enter the gap between the rotating disk 135 and the extrusion push rod 136, so that the steel structure 12 falls under the limitation of the limit support plate 131 and is clamped into the interior of the steel structure limit arm plate 117.

[0030] Working principle: When the steel structure 12 is placed in the middle position of the two limit support plates 131, the second motor 134 is used to rotate the rotating disk 135, and the extrusion push rod 136 on the outer surface of the rotating disk 135 is pressed against the outer surface of the swing arm plate 132. At this time, the triangular limit plate 133 on the outer bottom surface of the swing arm plate 132 is clamped and limited to the bottom corner position of the steel structure 12. The interlaced force between the triangular limit plate 133 and the surface of the steel structure 12 is used to firmly limit the steel structure 12 inside the limit support plate 131. After the current steel structure 12 is cut by the cutting knife 113, the steel structure 12 falls under the limitation of the limiting support plate 131. The steel structure 12 falls under its own gravity, and the steel structure 12 cooperates to press down the raised end of the steel structure limiting arm plate 117, and the steel structure limiting arm plate 117 is swung, so that the fallen end of the steel structure limiting arm plate 117 is fitted with the bottom surface of the steel structure 12, and the steel structure limiting arm plate 117 is used to limit and fix the position of the steel structure 12. At the same time, the steel structure limiting arm plate 117 is horizontally overlapped by the overlapping support plate 115 to maintain the horizontal angle of the steel structure 12. After the steel structure 12 is clamped into the interior of the steel structure limiting arm plate 117, the steel structure 12 will squeeze and push the extrusion slider a2 inside the empty slot a1, and squeeze and push the extrusion slider a2 out under the guidance of the inclined groove a3. As the steel structure limiting arm plate 117 is gradually squeezed to form a horizontal angle, the inclined groove a3 on the outer surface of the extrusion slider a2 will slide and press on the top surface of the lifting pad 114. As the extrusion slider a2 continues to squeeze, the extrusion cavity a4 is compressed, and at the same time, the surface of the extrusion slider a2 is tightly fitted to the outer surface of the steel structure 12, thereby increasing the friction and anti-slip effect between the extrusion slider a2 and the steel structure 12. After the steel structure 12 is limited, the surface of the steel structure 12 is cut into two sections with the help of a cutting knife. At this time, the gravity of the tail end of the steel structure 12 is used to drive the steel structure limiting arm plate 117 to swing downward on the surface of the lifting pad 114. The swinging steel structure limiting arm plate 117 will form a 50° inclination angle under the limitation of the supporting limiting plate 116. At this time, the steel structure 12 inside the steel structure limiting arm plate 117 will be clamped by the inclination angle and squeezed by the weight of the steel structure 12 itself, so that the steel structure 12 will slide off the surface of the steel structure limiting arm plate 117.
