Description

Technical Field

[0001] The invention relates to the field of steel structure cutting, in particular to a steel structure shearing machine. Background Art

[0002] Steel structure is a type of building structure. Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Among them, according to the calculation and design, the metal plates used to make steel structure components generally have specific size requirements and shape requirements. Therefore, the metal plates need to be cut into the specific required shapes and sizes.

[0003] The existing technology for cutting metal sheets often uses a steel structure shearing machine, which uses the relative movement between two blades to apply a shear force to the metal sheet, thereby cutting the metal sheet. As for the size and style requirements, the steel sheet is cut into various shapes by changing the angle between the metal sheet and the blade.

[0004] However, when it is necessary to use a steel structure shearing machine to cut metal sheets, in order to ensure the cutting effect, it is necessary to first determine the cutting line on the metal sheet, and then insert the metal sheet into the steel structure shearing machine after marking and positioning, so that the blade is aligned with the cutting line that has been marked on the metal sheet. This makes the preparation time of each metal sheet long, which affects the cutting efficiency of the metal sheet. Summary of the invention

[0005] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides a steel structure shearing machine which can quickly determine the cutting position.

[0006] Technical solution: A steel structure shearing machine, including: a machine body, a loading platform, a control main board, a blade, a pressing column and a pressing spring; also including: a rotating tray rotatably connected to the loading platform; a fixed screw arranged on the loading platform; an angle scale connected to the rotating tray; an indicator arrow connected to the loading platform; a mounting frame fixedly connected to the machine body; a servo motor a fixedly connected to the mounting frame; a moving screw rotatably connected to the mounting frame, the output end of the servo motor a is fixed to the moving screw; a cylinder threadedly connected to the moving screw; a suction cup fixedly connected to the telescopic end of the cylinder; a positioning ray head fixedly connected to the bottom of the mounting frame.

[0007] A further technical solution is that the moving distance of the suction cup is the distance between the positioning ray head emitted by the positioning ray head and the cutting line where the blade cuts the metal plate.

[0008] Its further technical solution is that it also includes: a moving block arranged on the rotating tray; a limiting plate slidably connected to the moving block; and a limiting spring fixedly connected between the moving block and the limiting plate.

[0010] Its further technical solution is that it also includes: a mounting plate fixedly connected to the rear side of the machine body; a material transfer roller rotatably connected to the mounting plate; a servo motor b fixedly connected to the mounting plate, the servo motor b being connected to the material transfer roller; a transmission wheel fixedly connected to the ends of all the material transfer rollers; and a transmission belt wound between two adjacent transmission wheels.

[0011] A further technical solution thereof is to further include: rotating a grinding wheel connected to the mounting plate.

[0012] A further technical solution thereof is that it also includes: a large gear fixedly connected to one of the material transfer rollers; a small gear fixedly connected to the grinding wheel, and the large gear and the small gear are meshed with each other.

[0013] Its further technical solution is that it also includes: a mounting support plate fixedly connected to the mounting plate; a pressing wheel slidably connected in the mounting support plate; and a pressure spring fixedly connected between the pressing wheel and the mounting support plate.

[0015] A further technical solution is that it also includes: a contact pad fixedly connected to the bottom of the pressing column.

[0016] Beneficial effects: 1. When using the shearing machine, the cutting line angle of the steel plate can be quickly determined by rotating the rotating tray in conjunction with the indicating arrow mark and the angle scale, and then the cutting line position of the steel plate can be quickly determined using the positioning line of the positioning ray head, thereby greatly reducing the cutting preparation time of the steel plate, thereby improving the cutting efficiency of the steel plate, and at the same time being able to conveniently cut the steel plate; the movable suction cup can accurately transport the steel plate to ensure the accuracy of the position of the steel plate after adjustment.

[0017] 2. When using the shearing machine, by using a limiting plate that can limit the position of the steel plate, the relative position of the steel plate and the rotating pallet is not easily changed, thereby improving the use effect of the rotating pallet and the cutting accuracy of the steel plate. At the same time, the flexible contact between the limiting plate and the steel plate can also enable the limiting plate and the steel plate to cooperate flexibly, thereby preventing the limiting plate from jamming the steel plate and affecting the normal processing of the steel plate.

[0018] 3. When using the shearing machine, the sheared steel plates are collected by transporting them using a feed roller, a transition conveyor belt is used to allow the steel plates to fall onto the feed roller more safely, and a grinding wheel is used to grind the cutting position of the steel plate to improve the cutting effect of the steel plate. The transmission between the large gear and the small gear makes the rotation speed of the grinding wheel much greater than that of the feed roller, thereby improving the grinding effect of the grinding wheel. The pressure spring acts on the steel plate through the pressing wheel, so that the steel plate is close to the grinding wheel and the grinding effect of the grinding wheel is improved.

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Embodiment 1: In this embodiment, specifically, the metal plate to be cut is a steel plate, and the following description will be based on the steel plate as the cutting object.

[0032] See also Figure 1 and Figure 3 , including: a body 1, a processing port for steel plates to pass through is provided in the middle of the body 1; a loading platform 101 installed on the front side of the body 1; a control mainboard 102 installed on the front side of the upper part of the body 1, the control mainboard 102 is used by workers to control the entire shearing machine; a blade 103 slidably installed in the processing port of the body 1, the body 1 controls the blade 103 to move to cut the steel plate; a pressing column 104 slidably installed on the front side of the body 1, the pressing column 104 is provided with four, The machine body 1 controls the pressing column 104 to move up and down; the pressing spring 105 is sleeved on the pressing column 104, and the pressing spring 105 is fixed between the pressing column 104 and the machine body 1. Before the steel plate is cut, the machine body 1 controls the pressing column 104 to move down and contact the steel plate, and cooperates with the pressing spring 105 to press and fix the position of the steel plate; the contact pad 8 installed at the bottom of the pressing column 104 is used to buffer the contact between the pressing column 104 and the steel plate to prevent the pressing column 104 from scratching the steel plate.

[0033] See also Figure 1 and Figure 4, including: a rotating tray 2 rotatably installed in the middle of the loading platform 101, after the steel plate is placed on the rotating tray 2, the rotating tray 2 is rotated to adjust the angle position of the cutting line; an angle scale 201 installed on the rotating tray 2; an indicator arrow 202 installed on the loading platform 101, the indicator arrow 202 cooperates with the angle scale 201 to quickly determine the rotation angle of the rotating tray 2; a fixed screw 203 threadedly installed on the loading platform 101, the fixed screw 203 contacts the rotating tray 2, and as the fixed screw 203 continues to rotate, the distance between the fixed screw 203 and the rotating tray 2 is reduced, thereby fixing the angle of the rotating tray 2 after rotation.

[0034] See also Figure 1 , Figure 5 and Figure 6 , including: a mounting frame 301 installed on the front side of the machine body 1; a servo motor a302 installed in the mounting frame 301; a moving screw 303 installed in the mounting frame 301, and the output end of the servo motor a302 is fixed to the moving screw 303, thereby controlling the forward and reverse rotation of the moving screw 303; a cylinder 304 threadedly installed on the moving screw 303, and the moving screw 303 rotates forward and backward to control the cylinder 304 to move forward and backward; a suction cup 3 installed on the telescopic end of the cylinder 304, and the telescopic end of the cylinder 304 is extended and retracted to control the suction cup 3 to move up and down, and the control main board 102 controls the suction cup 3 to adsorb the steel plate; a positioning ray head 305 installed below the mounting frame 301, and the positioning ray head 305 projects a left-right positioning line directly below the mounting frame 301, and the moving distance of the cylinder 304 is the distance from the positioning line to the cutting line of the blade 103.

[0035] First, rotate the rotating tray 2 according to the angle at which the steel plate needs to be cut. The indicating arrow 202 and the angle scale 201 enable the worker to quickly determine the angle at which the rotating tray 2 needs to be rotated. After the rotating tray 2 rotates, place the steel plate on the rotating tray 2, and turn the rotating tray 2 back to its initial position. Turn the fixing screw 203 to fix the position of the rotating tray 2. Then, push the steel plate backward so that the required cutting line of the steel plate is aligned with the positioning line projected by the positioning ray head 305. Then, operate the control main board 102 to control the cylinder 304 to drive the suction cup 3 to move downward to contact the steel plate and adsorb and fix the steel plate. Then, the cylinder 304 moves the steel plate upward through the suction cup 3, and then rotates and moves the steel plate backward through the moving screw 303 to align the cutting line of the steel plate with the cutting line of the blade 103. Then, move the steel plate downward to release the fixation of the steel plate. The suction cup 3 moves back to the initial position on the front side, move the pressing column 104 downward to fix the steel plate, and move the blade 103 to cut the steel plate, thereby completing the cutting process of the steel plate.

[0036] When using the shearing machine, the cutting line angle of the steel plate is quickly determined by rotating the rotating tray 2 in conjunction with the indicating arrow mark 202 and the angle mark 201, and then the cutting line position of the steel plate is quickly determined using the positioning line of the positioning ray head 305, thereby greatly reducing the cutting preparation time of the steel plate, thereby improving the cutting efficiency of the steel plate, and at the same time being able to conveniently cut the steel plate; the movable suction cup 3 can accurately transport the steel plate to ensure the accuracy of the position of the steel plate after adjustment.

[0037] See also Figure 1 , Figure 7 and Figure 8 , including: a double-headed screw 401 rotatably mounted on the lower part of the rotating tray 2, and the threads of the two ends thereof are set in opposite directions; moving blocks 402 are threadedly mounted at both ends of the double-headed screw 401, and the moving blocks 402 are slidably connected to the rotating tray 2, and the double-headed screw 401 rotates to control the two moving blocks 402 to move synchronously and in opposite directions, and the double-headed screw 401 controls the moving blocks 402 to synchronously move closer to or apart from each other; a limiting plate 4 slidably mounted on the moving block 402, and the limiting plate 4 limits the position of the steel plate placed on the rotating tray 2; a limiting spring 403 sleeved on the moving block 402, the limiting spring 403 is fixed between the moving block 402 and the limiting plate 4, and the limiting spring 403 makes the limiting plate 4 flexibly contact with the steel plate; an adjusting rod 404 rotatably mounted on the lower part of the rotating tray 2, and the adjusting rod 404 is perpendicular to the double-headed screw 401; bevel gears 405 respectively mounted on the adjusting rod 404 and the double-headed screw 401, and the two bevel gears 405 are meshed with each other.

[0038] After placing the steel plate on the rotating tray 2, rotate the adjusting rod 404 to make the two limiting plates 4 approach each other and move them to the left and right sides of the steel plate to limit the left and right side positions of the steel plate. Therefore, when the rotating tray 2 rotates the steel plate to change the cutting angle, the relative position of the steel plate and the rotating tray 2 is not easy to change. When the steel plate needs to be moved to align the cutting line of the steel plate with the positioning line of the positioning ray head 305, the steel plate can be moved obliquely. The oblique position is a direction perpendicular to the double-headed screw 401. Because the cutting line of the obliquely moved steel plate is always parallel to the positioning line, the angular position of the cutting line of the steel plate is not offset. The length of the positioning line and the blade 103 also enables the steel plate to have a large range of movement.

[0039] When using the shearing machine, by using the limiting plate 4 that can limit the position of the steel plate, the relative position of the steel plate and the rotating tray 2 is not easily changed, the use effect of the rotating tray 2 is improved, and the cutting accuracy of the steel plate is improved. At the same time, the flexible contact between the limiting plate 4 and the steel plate can also make the limiting plate 4 and the steel plate flexibly cooperate, preventing the limiting plate 4 from jamming the steel plate and affecting the normal processing of the steel plate.

[0040] See also Figure 1 and Fig. 9 , including: a mounting plate 501 mounted on the rear side of the machine body 1, the mounting plate 501 is below the processing port of the machine body 1; a feed roller 5 mounted on the mounting plate 501, and five feed rollers 5 are arranged; a servo motor b502 mounted on the mounting plate 501; a transmission wheel 503 mounted on the left end of each feed roller 5, the servo motor b502 and the frontmost transmission wheel 503 are driven by a conveyor belt group to drive the frontmost feed roller 5 to rotate; a transmission belt 504 wound between two adjacent transmission wheels 503, the transmission belt 504 makes all the feed rollers 5 rotate synchronously to transport the steel plate; a transition conveyor belt 7 mounted on the rear side of the machine body 1, the transition conveyor belt 7 is between the processing port of the machine body 1 and the frontmost feed roller 5.

[0041] See also Figure 1 , Fig. 9 and Fig.10 , including: a grinding wheel 6 rotatably mounted on a mounting plate 501, the grinding wheel 6 being between the material transfer rollers 5; a large gear 601 mounted on the left side of a material transfer roller 5 on the front side of the grinding wheel 6; a small gear 602 mounted on the left side of the grinding wheel 6, the large gear 601 and the small gear 602 being meshed; a mounting support plate 603 mounted on the mounting plate 501; a pressing wheel 604 slidably mounted in the mounting support plate 603, the pressing wheel 604 being above the grinding wheel 6; a pressure spring 605 mounted between the mounting support plate 603 and the pressing wheel 604, the pressure spring 605 acting to make the pressing wheel 604 close to the grinding wheel 6.

[0042] When the steel plate that has completed cutting is dropped from the rear side of the processing port of the machine body 1, it will be moved to the feed roller 5 by the transition conveyor 7 and transported backwards for collection by the feed roller 5. The transition conveyor 7 allows the steel plate to fall onto the feed roller 5 more safely. Then, when the steel plate is transported to contact with the grinding wheel 6, the grinding wheel 6 grinds the cutting position of the steel plate to improve the cutting effect of the steel plate. The transmission between the large gear 601 and the small gear 602 makes the rotation speed of the grinding wheel 6 much greater than that of the feed roller 5, thereby improving the grinding effect of the grinding wheel 6. The pressure spring 605 acts on the steel plate through the pressing wheel 604, so that the steel plate is close to the grinding wheel 6 to improve the grinding effect of the grinding wheel 6.

[0043] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
