Description

Technical Field

[0001] The invention belongs to the technical field of grinding and trimming equipment, and in particular relates to a curtain wall cutting device for building curtain wall construction. Background Art

[0002] In the field of curtain wall processing, cutting is a key link. Traditional cutting can only roughly divide the materials, while grinding is an indispensable means of fine cutting. It can accurately grind the edges after cutting, remove burrs, unevenness and slight deviations, so that the size and shape of the curtain wall materials meet higher precision requirements, ensure seamless splicing of panels, and effectively improve the overall quality, aesthetics and structural stability of the curtain wall.

[0003] At present, in the cutting of curtain walls, it is usually necessary to use a special cutting tool (such as a circular saw blade, etc.) to cut the curtain wall according to the set specifications. The cutting tool generally cuts the curtain wall roughly into the set specifications, and then finely trims the curtain wall by grinding and trimming to make the curtain wall size meet the use requirements, such as a curtain wall cutting device for building curtain wall construction disclosed in patent announcement number CN117817484A;

[0004] When installing curtain walls, errors in processing and on-site splicing often make it difficult for the curtain walls to meet installation requirements according to the set dimensions. If the on-site dimensions are smaller than the set values, the curtain walls cannot be assembled, or the joints after assembly are too large. Due to the limitations of the construction site, large-scale cutting equipment is difficult to bring in, and most operations rely on manual handheld cutting machines or grinders. When manually operating such a fine cutting method of grinding, the control of grinding size and pressure is weak, and cutting errors are easy to occur, resulting in the scrapping of the curtain wall.

[0040] The dust suction unit 11 is installed on the top of the L-shaped plate 4, and absorbs and collects the dust generated during trimming. The dust suction unit 11 includes a collection box 111 fixedly installed on the top of the horizontal part of the L-shaped plate 4, and a partition 112 is fixedly installed inside the collection box 111, and the controller 3 is installed on the top of the collection box 111. A filter 113 is fixedly provided between the lower end of the partition 112 and the inner bottom of the collection box 111, and a suction scoop 114 corresponding to the position of the filter 113 is fixedly inserted on the side wall of the collection box 111. A suction pump 115 is fixedly installed on the inner wall of the collection box 111 on the side of the filter 113 away from the suction scoop 114, and an air outlet end of the suction pump 115 passes through the side wall of the collection box 111, and the suction pump 115 is electrically connected to the controller 3.

[0041] The two clamping mechanisms 14 are respectively arranged on the two vertical side walls of the U-shaped plate 2, and are used to clamp and fix the curtain wall.

The temperature switch 123 is electrically connected to the controller 3. The controller 3 controls the operation of the electric heating rod 122 according to the electrical signal output by the pressure switch 105. When the temperature of the temperature switch 123 rises, under the action of thermal expansion, the metal parts inside it will expand and drive the moving contact to close. This is an existing mature technology, so it will not be described here.

[0042] The operating principle of the present invention is now described as follows: the height of the U-shaped plate 2 is adjusted to a suitable height by adjusting the bracket 1 (the side wall of the adjusting bracket 1 is provided with a stud, and the side wall of the adjusting bracket 1 is slidably connected to the bottom of the U-shaped plate 2, and the side wall of the U-shaped plate 2 is provided with an adjustment hole matching the stud. When adjusting the height of the U-shaped plate 2, the nut on the stud is loosened, and then the U-shaped plate 2 is pulled up, and after the U-shaped plate 2 reaches a suitable height, the nut is tightened again. The height of adjustment is set according to the thickness of the curtain wall), and then the curtain wall to be cut is placed on the placement surface of the adjusting bracket 1 (refer to Figure 1 , Figure 1The middle dotted line represents the curtain wall), at this time, the lower half of the grinding wheel 63 is opposite to the surface to be trimmed of the curtain wall, and then the U-shaped plate 2 is placed in a suitable position above the curtain wall (the horizontal distance between the side wall of the U-shaped plate 2 and the surface to be trimmed of the curtain wall is generally 10 cm), and then the curtain wall is locked and fixed by two clamping mechanisms 14 (the clamping mechanism 14 includes a clamping plate, a clamping bolt, a limit rod and other components, and the clamping bolt is screwed to move the clamping plate toward the curtain wall, so that the curtain wall and the U-shaped plate 2 are locked together to ensure the stability of the cutting process), and then the insulating screw 93 is screwed to move the conductive ring 94 to a set position (the set position is set based on the width of the curtain wall that needs to be trimmed), and then the controller 3 is connected to the external power supply circuit, and the controller 3 is started;

[0043] After the controller 3 is started, it will immediately control the electromagnetic suction rod 73 to work, and the telescopic end of the electromagnetic suction rod 73 will pull the motor drive assembly 61 to move through the moving block 71 (the electromagnetic suction rod 73 includes an outer tube, a telescopic rod, an electromagnetic part, an iron core, an elastic part and other components. When the electromagnetic part is energized, it generates a magnetic attraction force on the iron core, and the iron core can drive the telescopic rod to move in the direction of the outer tube and compress the elastic part. When the electromagnetic part is powered off, the telescopic rod will move back and reset under the rebound and reset action of the elastic part), until the side wall of the grinding wheel 63 at the motor drive assembly 61 is against the surface of the curtain wall to be trimmed. After the electromagnetic suction rod 73 works for 2 seconds, the controller 3 controls the motor drive assembly 61 to work, and the motor drive assembly 61 controls the mounting plate 62 to rotate, so that the grinding wheel 63 rotates synchronously, and the rotating grinding wheel 63 can trim and cut the side wall of the curtain wall;

[0044] When the controller 3 controls the motor drive assembly 61 to work, the controller 3 will synchronously control the two electromagnetic blocks 103 to work. The two electromagnetic blocks 103 are energized to generate magnetic attraction, so that they are adsorbed and fixed to the iron bar 104 on the same side. As the grinding wheel 63 grinds and trims the side wall of the curtain wall, the horizontal distance between the side wall of the curtain wall and the U-shaped plate 2 gradually decreases. Under the action of the electromagnetic suction rod 73, the motor drive assembly 61 will drive the grinding wheel 63 to gradually move in the direction of the U-shaped plate 2, so that the insulating positioning rod 8 can be driven to move synchronously through the moving block 71. Since in the initial state, the electric The current passed through the magnetic suction rod 73 is fixed, so the magnetic suction force it generates is constant. At this time, the electromagnetic suction rod 73 drives the grinding wheel 63 to exert a constant trimming pressure on the side wall of the curtain wall. As the side wall of the curtain wall is polished and trimmed, the grinding wheel 63 moves toward the direction of the U-shaped plate 2, so the elastic element inside the electromagnetic suction rod 73 is further compressed. At this time, the reverse force exerted by the elastic part of the electromagnetic suction rod 73 on its telescopic end is further increased, so the magnetic suction force generated by the electromagnetic part of the electromagnetic suction rod 73 is further offset. At this time, the electromagnetic suction rod 73 attracts the moving block 71 to drive the motor drive assembly 61 and The trimming pressure of the grinding wheel 63 on the side wall of the curtain wall is reduced, and because the insulating positioning rod 8 moves synchronously with the moving block 71, the supporting end 95 on the insulating positioning rod 8 will approach the pressure switch 105 and apply pressure to the moving contact of the pressure switch 105 until the supporting end 95 squeezes and closes the moving contact of the pressure switch 105. The pressure switch 105 will output an electrical signal to the controller 3. After receiving the closing electrical signal of the pressure switch 105, the controller 3 will immediately control the current passed into the electromagnetic suction rod 73 to increase by one gear (for example, the initial current passed is 2A, The current increased once is 0.4A, and the current increased once can be set according to the material of the curtain wall. Since the grinding wheel 63 is at a certain distance from the side wall of the curtain wall in the initial state, the current initially supplied needs to ensure that the grinding wheel 63 moves a sufficiently large distance and applies a sufficiently large pressure to the side wall of the curtain wall), so that the electromagnetic suction force applied by the electromagnetic part of the electromagnetic suction rod 73 to its telescopic end is further increased, so that the trimming pressure of the grinding wheel 63 on the curtain wall is increased, so as to ensure that a stable trimming pressure is applied to the curtain wall to ensure the trimming effect and efficiency;

[0045] As the side wall of the curtain wall is gradually polished and trimmed to the set position (i.e., the position where the part to be trimmed and removed is completely removed), the moving block 71 drives the two arc-shaped conductive blocks 97 to move to the conductive ring 94 through the insulating positioning rod 8 and contact the conductive ring 94. Since the two arc-shaped conductive blocks 97 contact the conductive ring 94 at the same time, the connection circuit between the arc-shaped conductive block 97, the conductive ring 94 and the electromagnetic switch 98 is connected, so that the moving contact of the electromagnetic switch 98 is magnetically closed, and the electromagnetic switch 98 will immediately output a closed electrical signal to the controller 3. After receiving the closed electrical signal, the controller 3 will immediately control the motor drive assembly 61 to stop working and stop the grinding wheel 63 from rotating to avoid excessive polishing of the curtain wall and ensure the accuracy of the polishing size. Subsequently, the controller 3 controls the electromagnetic suction rod 73 to cut off the power. Under the action of the elastic member inside it, the moving block 71 will drive the motor drive assembly 61 and the grinding wheel 63 to move back and reset. After the electromagnetic suction rod 73 is powered off, the controller 3 will control the screw drive mechanism 5 to perform timing work ( The screw drive mechanism 5 includes components such as a motor, a bearing, a transmission screw, a screw nut, and a connecting block. The screw nut is connected to the transmission screw in a transmission manner. The screw nut is inserted into the side wall of the connecting block. The motor drives the transmission screw to rotate, and drives the connecting block to move by driving the screw nut. The connecting block is fixedly connected to the L-shaped plate 4, so that the L-shaped plate 4 moves synchronously). The screw drive mechanism 5 can drive the L-shaped plate 4 to move linearly along the horizontal part of the U-shaped plate 2, so that the grinding wheel 63 can be driven to move to the next trimming and grinding position through the L-shaped plate 4 and other components, and the above steps are repeated to perform trimming and grinding on the next position (for example, the grinding coverage length of the grinding wheel 63 on the side wall of the curtain wall is 5 cm, and the moving distance of the L-shaped plate 4 driven by the screw drive mechanism 5 is 4 cm, so that when the grinding wheel 63 grinds the next position, the grinding range of the next position can overlap with the previous position, thereby avoiding the phenomenon of ungrinding between adjacent grinding positions). Repeat the above steps to complete the trimming and cutting of the curtain wall;

[0046] Among them, after the controller 3 is initially started, the controller 3 will control the suction pump 115 to work, and the suction end of the suction pump 115 can suck in external air through the suction scoop 114. Under the action of negative pressure suction, the dust generated during trimming and grinding will also enter the collection box 111 with the air flow and be intercepted by the filter 113 in the collection box 111 (the side wall of the collection box 111 is provided with a waste outlet, and the waste outlet is provided with a cover plate for discharging dust. Secondly, the collection box 111 is provided with a cleaning structure for preventing the filter 113 from being blocked, for example, a brush is driven to rotate by a micro motor to clean the dust on the surface of the filter 113 to prevent the filter 113 from being blocked and affecting the ventilation efficiency). When the machine drive assembly 61 is working, the controller 3 will control the electric heating rod 122 to work synchronously, and control the current passed into the electric heating rod 122 to gradually increase, so that within 2 minutes, the heating temperature of the electric heating rod 122 reaches 60°C±3°C. When the grinding efficiency of the grinding wheel 63 is normal, since the grinding wheel 63 removes the excess part of the curtain wall at a faster speed, the support end 95 will touch and press the closing pressure switch 105 within 2 minutes. On the contrary, when the grinding wheel 63 is excessively worn, the grinding efficiency of the grinding wheel 63 on the side wall of the curtain wall becomes low. At this time, the support end 95 cannot touch and press the closing pressure switch 105 within 2 minutes. During the operation of the electric heating rod 122, since the suction pump 115 continues to work, the airflow output from its outlet end will take away the electric heating rod 12 2 and the heat around the temperature switch 123, so within 2 minutes, the heat at the temperature switch 123 cannot reach the set temperature, so that its own moving contact is closed. On the contrary, when the electric heating rod 122 continues to work for more than 2 minutes, the moving contact of the temperature switch 123 will be closed under the action of temperature, and the controller 3 will receive the closing electrical signal of the temperature switch 123. At this time, the controller 3 will alarm through its own alarm module (such as a buzzer) and control the motor drive component 61 to stop working at the same time. The staff should check the wear condition of the grinding wheel 63 in time and replace the grinding wheel 63. Within 2 minutes, if the controller 3 receives the closing electrical signal of the pressure switch 105, it means that the grinding wheel 63 has a strong impact on the curtain wall. The grinding efficiency meets the cutting requirements, so after the controller 3 receives the closing electrical signal of the pressure switch 105, the controller 3 will control the electric heating rod 122 and the temperature switch 123 to cut off the power and stop working for at least 5 minutes. At this time, the airflow delivered by the air pump will take away the heat around the electric heating rod 122 and the temperature switch 123, so that they can return to normal temperature. After 5 minutes, when the controller 3 receives the closing electrical signal of the pressure switch 105 again, in addition to controlling the current passed into the electromagnetic suction rod 73 to increase, the controller 3 will also synchronously control the electric heating rod 122 and the temperature switch 123 to resume work, so as to continue to measure whether the grinding efficiency of the grinding wheel 63 meets the requirements, and when the grinding efficiency is low, the controller 3 will automatically remind the personnel to replace the grinding wheel 63.

[0047] Among them, the airflow delivered by the suction pump 115 takes away part of the heat and enters the hollow block 125 through the exhaust pipe 124, and is ejected through the air outlet inclined hole 126, so as to preheat the position to be polished, avoid the next polished and trimmed position from having a large temperature difference due to the high temperature generated during polishing and trimming, and prevent the curtain wall from having excessive thermal stress concentration due to the large temperature difference, resulting in microscopic damage inside it.

[0048] Embodiment 2:

[0049] Reference Fig. 9 The difference between this embodiment and embodiment 1 is that a step groove is provided on the side wall of the mounting plate 62 at the outer side of the grinding wheel 63, and a detachable annular cutting piece 13 is installed on the groove wall of the step groove.

[0050] In this embodiment, when the width of the curtain wall that needs to be trimmed and removed is large (for example, greater than 5 cm), an annular cutting piece 13 can be installed on the side wall of the mounting plate 62, and the height of the U-shaped plate 2 can be adjusted to a suitable position by adjusting the bracket 1 so that the annular cutting piece 13 is on one side of the curtain wall. Then, the cutting button of the controller 3 is activated, and the controller 3 controls the screw drive mechanism 5 to work continuously, driving the annular cutting piece 13 to move in a straight line, and at the same time controls the motor drive assembly 61 to work. The motor drive assembly 61 drives the annular cutting piece 13 to rotate, so that in the process of linear movement, the excess part of the curtain wall can be cut off. When cutting it off, a grinding allowance of 1 cm is reserved. After the curtain wall is cut off, the annular cutting piece 13 is removed, and the remaining grinding allowance of the curtain wall is polished and removed according to the steps in Example 1, which can ensure both the cutting efficiency and the refined trimming and cutting of the curtain wall.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
