Abstract
Description
Technical Field
[0001] This invention relates to the field of cutting and processing equipment technology, and more specifically, to a cutting and processing equipment for raw materials used in the production of fireproof windows. Background Technology
[0002] Fire-resistant windows are windows that, along with their frames, can meet the requirements for fire resistance stability and fire resistance integrity within a certain period of time. The fire-resistant requirements of fire-resistant windows mean that their window frame structure is mostly steel. In the production process of fire-resistant windows, in order to ensure that the window frame meets the dimensional requirements, it is necessary to use cutting equipment to cut it. However, when cutting steel frames, the required cutting thickness varies depending on the fire resistance requirements. Cutting equipment is difficult to use for cutting steel frames of different thicknesses, and the cutting difficulty will increase as the thickness of the steel frame increases. This results in poor applicability and increases the cutting difficulty and cost.
[0003] Based on this, a cutting and processing device for raw materials used in the production of fireproof windows is proposed. Summary of the Invention
[0004] The main objective of this invention is to provide a cutting and processing device for raw materials used in the production of fireproof windows, so as to overcome the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides a cutting and processing device for fireproof window production raw materials, including a base. A fixing plate is fixedly installed in the middle of the upper surface of the base. A first adjusting frame is fixedly installed on both sides of the middle of the upper surface of the fixing plate. A second adjusting frame is fixedly installed on both sides of the middle of the lower surface of the fixing plate. An inclined first adjusting groove is opened through the upper part of both sides of the outer surface of the first adjusting frame. An inclined second adjusting groove is opened through the lower part of both sides of the outer surface of the second adjusting frame. The first adjusting frame and the second adjusting frame are slidably inserted and installed with two sets of fixing frames through the inner surfaces of the first adjusting groove and the second adjusting groove. A connecting shaft is movably inserted into one end of the fixed frame, and a cutting wheel is fitted on the outer surface of the output end of the connecting shaft. A motor is fixedly installed on one side of the outer surface of the fixed frame, and the output end of the motor is fixedly connected to the other end of the connecting shaft. A support rod is movably inserted through the center of the front end of the upper surface of the base. An adapter is fixedly installed on the lower surface of the support rod.

A first compression spring is movably sleeved on the center of the outer surface of the support rod. The two ends of the first compression spring are in contact with the base and the adapter, respectively. A second helical gear is movably inserted through the center of the lower surface of the adapter. The second helical gear and the first helical gear are meshed with each other. An assembly cylinder is protruding and fixedly installed on the center of the lower surface of the second helical gear. A grinding rod is movably inserted into the inner surface of the assembly cylinder. A second compression spring is placed between the upper surface of the grinding rod and the inner top surface of the assembly cylinder.
[0006] As a further improvement of the present invention, a shaft is provided at the lower part of the front end and the rear end of the outer surface of the base. A support roller is rolled and installed on the outer surface of the base through the shaft. A support frame is fixedly installed on the middle of both sides of the outer surface of the base. An movable opening is provided through the middle of both sides of the outer surface of the base. A bidirectional screw is rotatably inserted and installed at the middle of both ends of the inner surface of the support frame.
[0007] As a further improvement of the present invention, an I-shaped limiting frame is movably installed on the middle of both sides of the inner surface of the base. A limiting roller is rotatably hinged to both ends of the outer surface of the two sets of limiting frames on the side closer to each other. An adjusting rod is movably hinged to both ends of the middle of the outer surface of the two sets of limiting frames on the side farther from each other. An adjusting screw block is movably hinged to both ends of the adjusting rod. The adjusting screw block is spirally sleeved on the outer surface of the bidirectional screw.
[0008] As a further improvement of the present invention, both the first adjustment groove and the second adjustment groove are inclined. The upper part of the outer surface of the fixing frame is slidably inserted into the first adjustment groove, and both ends of the fixing frame are slidably inserted into the second adjustment groove.

The output end of the positioning pin is spirally inserted through the grinding rod, and the lower surface of the grinding rod extends outside the assembly cylinder.
[0010] The beneficial effects of this invention are: This invention achieves layered cutting of steel frames by setting up several sets of cutting structures and adjusting the height difference of the cutting structures. This makes it suitable for cutting steel frames of different thicknesses. At the same time, the cutting resistance of a single set of cutting structures can be distributed accordingly when using layered cutting, thereby reducing the cutting difficulty of steel frames and further improving the cutting efficiency of steel frames. This invention can grind the surface of the steel frame at the cutting gap as the cutting of the steel frame progresses, thereby removing the protruding burrs from the cutting gap and improving the cutting quality of the steel frame.

[0016] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.
[0017] Please see Figures 1-6 As shown, a cutting and processing device for fireproof window production raw materials includes a base 1. A shaft is provided at the lower front and rear ends of the outer surface of the base 1. A support roller 101 is rolled and mounted on the outer surface of the base 1 via the shaft. A support frame 102 is fixedly mounted protruding from the middle of both sides of the outer surface of the base 1. An movable opening is provided through the middle of both sides of the outer surface of the base 1. A bidirectional screw 103 is rotatably inserted and mounted at the middle of both ends of the inner surface of the support frame 102. An "I"-shaped limiting frame 2 is movably mounted on the middle of both sides of the inner surface of the base 1. A limiting roller 201 is rotatably hinged to the two ends of the outer surface of the two sets of limiting frames 2 on the side closest to each other. An adjusting rod 202 is movably hinged to the two ends of the middle of the outer surface of the two sets of limiting frames 2 on the side furthest from each other. An adjusting screw block 203 is movably hinged to both ends of the adjusting rod 202. The adjusting screw block 203 is spirally mounted on the outer surface of the bidirectional screw 103. It should be noted that the support roller 101 can provide rolling support for the steel frame, so as to push the steel frame to slide and cut. By rotating the bidirectional screw 103 clockwise and counterclockwise, the adjusting screw block 203, which is spirally sleeved on the outer surface, can be controlled to move laterally closer and further away from each other. Since the adjusting rod 202, the adjusting screw block 203, and the limiting frame 2 are all in a movable hinge state, when the adjusting screw block 203 is in a moving state, the connection angle between the adjusting rod 202 and the limiting frame 2 can be adjusted. Thus, the distance by which the limiting frame 2 protrudes relative to the base 1 can be adjusted by adjusting the angle of the adjusting rod 202. The movement of the limiting frame 2 drives the limiting roller 201 to limit and clamp the two sides of the steel frame to prevent the steel frame from shifting during the cutting process. By simultaneously setting limit frames 2 on both sides of the base 1, the cutting position of the steel frame can be adjusted. By rotating the bidirectional screws 103 on both sides of the base 1 to different degrees, the protrusion distance of the limit frames 2 relative to the sides of the base 1 can be controlled, thereby adjusting the cutting position of the steel frame to ensure that the required cutting position is aligned with the cutting wheel 403.
[0018] A fixing plate 3 is fixedly installed in the middle of the upper surface of the base 1. A first adjusting frame 301 is fixedly installed on both sides of the middle of the upper surface of the fixing plate 3. A second adjusting frame 302 is fixedly installed on both sides of the middle of the lower surface of the fixing plate 3. An inclined first adjusting groove 303 is opened through the upper part of both sides of the outer surface of the first adjusting frame 301. An inclined second adjusting groove 304 is opened through the lower part of both sides of the outer surface of the second adjusting frame 302. Two sets of fixing frames 4 are slidably inserted and installed on the first adjusting frame 301 and the second adjusting frame 302 through the inner surfaces of the first adjusting groove 303 and the second adjusting groove 304. Both the first adjustment groove 303 and the second adjustment groove 304 are inclined. The upper part of the outer surface of the fixing frame 4 is slidably inserted into the first adjustment groove 303. The two ends of the fixing frame 4 are slidably inserted into the second adjustment groove 304 respectively. The upper part of the outer surface of the fixing frame 4 is provided with a bidirectional thread. Both ends of the upper part of the outer surface of the fixing frame 4 are spirally fitted with locking screw rings 401. The outer surface of the locking screw rings 401 is in contact with the outer surface of the first adjustment frame 301. One end of the fixing frame 4 is movably inserted and fitted with a connecting shaft 402. The outer surface of the output end of the connecting shaft 402 is limited and fitted with a cutting wheel 403. A motor 404 is fixedly installed on one side of the outer surface of the fixing frame 4. The output end of the motor 404 is fixedly connected to the other end of the connecting shaft 402. It should be noted that when both the first adjustment groove 303 and the second adjustment groove 304 are inclined, there will be a height difference between the fixed frame 4 located at different installation positions in the first adjustment groove 303 and the second adjustment groove 304. When there is a height difference between the fixed frame 4, the cutting wheel 403 can be controlled to adjust the cutting height difference. When the cutting position of the first set of cutting wheels 403 is half the thickness of the steel used in the steel frame, the cutting position of the second set of cutting wheels 403 needs to be set through the thickness of the steel. In this state, the motor 404 is started, and the first set of cutting wheels 403 can cut the upper half of the steel to make the steel present a cutting groove. After the first set of cutting wheels 403 finishes cutting, as the steel continues to advance, the second set of cutting wheels 403 will perform a secondary cut on the steel. Since the second set of cutting wheels 403 penetrates the thickness of the steel, it can cut the steel completely. At the same time, since the first set of cutting wheels 403 cuts a cutting groove in the upper half of the steel, the actual cutting position required by the second set of cutting wheels 403 is the lower half of the steel. With a cutting groove in the upper half of the steel, the resistance of the second set of cutting wheels 403 in cutting the lower half of the steel will be reduced, thereby reducing the cutting difficulty of steel of different thicknesses and improving cutting efficiency.
[0019] A support rod 5 is movably inserted through the middle of the front end of the upper surface of the base 1. An adapter 501 is fixedly installed on the lower surface of the support rod 5. A connecting frame 502 is fixedly installed on the middle of one side of the outer surface of the adapter 501. A first helical gear 503 is movably engaged at the other end of the connecting frame 502. A first compression spring 504 is movably sleeved on the middle of the outer surface of the support rod 5. The two ends of the first compression spring 504 are in contact with the base 1 and the adapter 501 respectively. A second helical gear 6 is movably inserted through the middle of the lower surface of the adapter 501. The second helical gear 6 and the first helical gear 503 are meshed with each other. It should be noted that when the first compression spring 504 is set and its two ends are in contact with the base 1 and the adapter 501 respectively, the elastic tension of the first compression spring 504 can push the adapter 501 to control the support rod 5 to press towards the support roller 101 by using the base 1 as the support point. When the steel of the steel frame is placed on the support roller 101 for cutting, the first helical gear 503, which is movably connected to the adapter 501 through the connecting frame 502, can press and contact the upper surface of the steel. At this time, as the cutting of the steel is advanced, the first helical gear 503 can be driven to rotate vertically relative to the steel. Since the first helical gear 503 and the second helical gear 6 are meshed with each other, the rotation of the first helical gear 503 can drive the second helical gear 6 to rotate synchronously.
[0020] A mounting cylinder 601 is fixedly installed in the middle of the lower surface of the second helical gear 6. A grinding rod 603 is movably inserted into the inner surface of the mounting cylinder 601. The lower surface of the grinding rod 603 extends outside the mounting cylinder 601. A second compression spring 604 is placed between the upper surface of the grinding rod 603 and the inner top surface of the mounting cylinder 601. A mounting groove 602 is opened through the middle of the front and rear ends of the outer surface of the mounting cylinder 601. A positioning pin 605 is slidably inserted into the inner surface of the two sets of mounting grooves 602. The output end of the positioning pin 605 is spirally inserted through the grinding rod 603. It should be noted that when the second helical gear 6 is rotating, it can drive the grinding rod 603 installed in the assembly cylinder 601 to rotate synchronously. When the grinding rod 603 and the cutting wheel 403 are on the same horizontal line, the rotating grinding rod 603 can grind the burrs at the cutting gap of the steel to improve the cutting quality. When the grinding rod 603 comes into contact with the steel surface, it can compress the second compression spring 604. As the grinding rod 603 continues to wear down, its protrusion relative to the assembly cylinder 601 decreases accordingly. At this time, the compressive force on the second compression spring 604, which is located between the upper surface of the grinding rod 603 and the inner top surface of the assembly cylinder 601, decreases synchronously. The second compression spring 604 can then elastically reset and push the grinding rod 603 to extend from inside the assembly cylinder 601 to the outside until the grinding rod 603 continues to contact the steel surface to carry out the grinding operation. As the grinding rod 603 wears down with continuous grinding, its protrusion relative to the assembly cylinder 601 decreases accordingly. The first helical gear 503 will remain in contact with the steel surface. Since the lower surface of the grinding rod 603 extends outside the assembly cylinder 601, when the grinding rod 603 contacts the steel surface, it is at the same horizontal level as the first helical gear 503. In this case, it can be seen that the first helical gear 503 is protruding relative to the assembly cylinder 601. As the grinding rod 603 wears down, the first helical gear 503 will indirectly support the assembly cylinder 601. In this case, the distance between the assembly cylinder 601 and the steel surface is sufficient for the second compression spring 604 to continuously push the grinding rod 603 out of the assembly cylinder 601, so as to avoid the problem that the first compression spring 504 pushes the assembly cylinder 601 into contact with the steel surface, causing the grinding rod 603 to be unable to extend.
[0021] In use, the steel frame material can first be placed on the support roller 101 and pushed until it contacts the cutting wheel 403. At this time, the adjusting screw block 203 can be moved laterally closer and further away by rotating the bidirectional screw 103 clockwise and counterclockwise. Since the adjusting rod 202, the adjusting screw block 203 and the limiting frame 2 are all in a movable hinge state, when the adjusting screw block 203 is in a moving state, the connection angle between the adjusting rod 202 and the limiting frame 2 can be adjusted. Thus, the protrusion distance of the limiting frame 2 relative to the base 1 can be adjusted by adjusting the angle of the adjusting rod 202 until the limiting roller 201 contacts both sides of the steel material and pushes the cutting position of the steel material to be aligned with the cutting wheel 403. At this point, the steel can be cut into layers according to its thickness. The steel is divided into an upper cutting layer and a lower cutting layer according to the center position of its thickness. The first fixing frame 4 is slidably adjusted along the first adjusting groove 303 according to the thickness of the upper cutting layer until the protruding cutting distance of the cutting wheel 403 fixed by the first fixing frame 4 relative to the steel matches the upper cutting layer of the steel. At this point, the locking screw 401 can be tightened to limit and fix the fixing frame 4. At the same time, the second fixing frame 4 can be slidably adjusted along the first adjusting groove 303 according to the overall thickness of the steel until the protruding cutting distance of the cutting wheel 403 fixed by the second fixing frame 4 relative to the steel matches the entire layer thickness of the steel. At this point, the locking screw 401 can be tightened to fix the fixing frame 4. After the cutting positions of the two fixing frames 4 are adjusted, the motor 404 can be started to control the cutting wheel 403 to cut the steel. During the cutting process, the first set of cutting wheels 403 can cut the upper half of the steel, creating a cutting groove in the upper part of the steel. After the first set of cutting wheels 403 finishes cutting, as the steel continues to advance, the second set of cutting wheels 403 will perform a second cut on the steel. Since the second set of cutting wheels 403 penetrates the thickness of the steel, it can cut the steel completely. At the same time, since the first set of cutting wheels 403 cuts a cutting groove in the upper half of the steel, the actual cutting position required by the second set of cutting wheels 403 is the lower half of the steel. With a cutting groove in the upper half of the steel, the resistance of the second set of cutting wheels 403 cutting the lower half of the steel will be reduced, thereby reducing the cutting difficulty of steel of different thicknesses and improving cutting efficiency. Secondly, as the steel continues to advance, the support rod 5 can be lifted and stretched. At this time, the first compression spring 504 will deform under the force. When the steel passes under the support rod 5, the lifting state of the support rod 5 can be released. At this time, the first compression spring 504 can use its own restoring elasticity to push the support rod 5 towards the upper surface of the steel with the base 1 as the support point. At this time, the first helical gear 503, which is movably connected to the adapter 501 through the connecting frame 502, can press and contact the upper surface of the steel. As the steel is cut and advanced... This will drive the first helical gear 503 to rotate vertically relative to the steel. Since the first helical gear 503 and the second helical gear 6 are meshed together, the rotation of the first helical gear 503 will drive the second helical gear 6 to rotate synchronously. When the second helical gear 6 is rotating, it will drive the grinding rod 603 installed in the assembly cylinder 601 to rotate synchronously. When the grinding rod 603 and the cutting wheel 403 are on the same horizontal line, the rotating grinding rod 603 can grind the burrs at the cutting gap of the steel to improve the cutting quality.
