Description

Technical Field

[0001] This utility model relates to the field of building cutting, specifically a curtain wall frame cutting device. Background Technology

[0002] Because different types of curtain walls have different dimensions, the corresponding frame dimensions will also vary. Therefore, the frame needs to be cut to the specified size before construction to be used with the curtain wall. Traditional frame cutting devices place the frame profile on the cutting table, use a clamping device to fix the frame profile, and move the cutting saw blade downward to cut the frame profile. During cutting, a large amount of high-temperature debris is generated, which can easily splash onto the operator and cause injury. Moreover, after each cut, the clamping device needs to be manually released to move the frame profile, which is quite cumbersome. As a result, the efficiency and safety of existing cutting devices for cutting frame profiles need to be further improved. Utility Model Content

[0020] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0021] Reference Figure 1 and Figure 2This utility model describes a curtain wall frame cutting device. The main structure includes a cutting table 1, which supports the frame profile being cut. The cutting table 1 is generally made of metal, and the frame profile is typically a rod-shaped or square tube structure. It is fitted onto the outside of the glass curtain wall for connection and support. A cutting frame 2 is slidably connected to the cutting table 1 laterally. The cutting frame 2 is driven to slide laterally using an existing drive device. A cutting saw blade 3 is rotatably connected to the cutting frame 2 via bearings. Specifically, a cutting motor is installed on the cutting frame 2, and the output shaft of the cutting motor is connected to the cutting saw blade 3 to drive its rotation. The cutting table 1 is equipped with... The cutting table 1 has a cutting groove 4 for use with the cutting saw blade 3. The cutting saw blade 3 extends downward into the cutting groove 4. This structure allows the rotating cutting saw blade 3 to cut the frame profile as it passes through the cutting table 1 when the frame profile is placed on it. Since part of the cutting saw blade 3 is located in the cutting groove 4 below the cutting table 1, it can completely cut the frame profile after passing through it, eliminating the need for manual movement of the cutting saw blade 3. This keeps the operator away from the cutting position, and the high-temperature debris generated during cutting is less likely to splash onto the operator, reducing safety hazards and greatly improving cutting safety. The cutting table 1 is fixed with a feeding device by welding or bolts. Channel 5, with a U-shaped longitudinal section, is used for feeding rod-shaped or square tube-shaped frame profiles. Multiple feeding rollers 6 are rotatably connected to the bottom of the feeding channel 5 via bearings. When the frame profile is placed into the feeding channel 5, its bottom contacts the multiple feeding rollers 6. The rotation of the feeding rollers 6 enables the lateral movement of the frame profile, allowing it to move to the cutting groove 4 for cutting, thus achieving automatic feeding of the frame profile. A pressure plate 7 is vertically slidably connected to the top of the feeding channel 5. A power assembly for controlling the vertical sliding of the pressure plate 7 is provided on the feeding channel 5. The bottom of the pressure plate 7 is fixed by welding or bolts. With multiple pressure blocks 8, after the frame profile is moved into place, the power component drives the pressure plate 7 to slide downwards, causing the multiple pressure blocks 8 to move downwards and press and fix the frame profile, thus restricting the frame profile to the feeding roller 6 and preventing it from moving further. This ensures the accuracy of the frame profile during cutting. After cutting, the pressure plate 7 slides upwards and resets under the drive of the power component, causing the pressure blocks 8 to separate from the frame profile. The rotation of the feeding roller 6 then drives the frame profile to continue moving and feeding. There is no need to manually release the restriction on the frame profile, making the movement and positioning of the frame profile more convenient and faster, and greatly improving the efficiency of frame profile cutting.

[0022] Preferred, refer to Figure 3The top of the feeding channel 5 is provided with a power groove 9. Preferably, the longitudinal section of the power groove 9 is also U-shaped. It is fixed to the top of the feeding channel 5 by welding or bolts. The power assembly is set in the power groove 9. Multiple vertical guide columns 10 are fixed in the power groove 9 by welding or bolts. The guide columns 10 penetrate the pressure plate 7 and are slidably connected to it. Multiple pressing blocks 8 at the bottom of the pressure plate 7 penetrate the bottom of the power groove 9 and extend into the feeding channel 5. The guide columns 10 provide guidance when the pressure plate 7 slides up and down, so that the pressing blocks 8 at each position at the bottom of the pressure plate 7 can slide up and down synchronously, thereby making the pressing and limiting of the frame profile more accurate and stable.

[0023] Preferably, the power assembly includes a power motor 11, a power shaft 12, and a cam 13. The power motor 11 is fixed to the side wall of the power groove 9 by welding or bolting. The power shaft 12 is fixed to the output shaft of the power motor 11 by welding or bolting. The cam 13 is welded or integrally formed and fixed to the power shaft 12. The edge of the cam 13 makes rolling contact with the top of the pressure plate 7. Multiple return springs 14 are provided between the pressure plate 7 and the top of the power groove 9. This structure ensures that when the power motor 11 drives the power shaft 12 to rotate, the power shaft... The long axis of the cam 13 on the upper part of the cam 12 contacts the top of the pressure plate 7, thereby driving the pressure plate 7 to slide downward, which in turn drives multiple pressure blocks 8 to slide downward to press and fix the frame profile. During this process, the return spring 14 is stretched. After the cutting is completed, the power motor 11 continues to drive the power shaft 12 to rotate, so that the long axis of the cam 13 separates from the pressure plate 7. Under the action of the return spring 14, the pressure plate 7 drives multiple pressure blocks 8 to slide upward and reset, thereby automatically contacting the pressure blocks 8 to press and fix the frame profile, making the up-and-down sliding drive of the power component on the pressure plate 7 smoother and more accurate.

[0024] Preferred, refer to Figure 4 The feeding channel 5 is rotatably connected to multiple rotating shafts 15 via bearings. The feeding channel 5 is equipped with a feeding motor 16 that drives one of the rotating shafts 15 to rotate. Specifically, the output shaft of the feeding motor 16 is fixedly connected to one of the rotating shafts 15 by welding or bolts. A synchronous belt 17 connects the multiple rotating shafts 15. The feeding rollers 6 are fixed to the rotating shafts 15 by welding or bolts. This structure can use the feeding motor 16 to drive two or more feeding rollers 6 to rotate, so as to achieve accurate feeding of the frame profile. Preferably, the rotating shafts 15 on at least two ends of the feeding rollers 6 are connected by the synchronous belt 17, so that the frame profile can enter and leave the feeding channel 5 by the feeding rollers 6 at the ends.

[0025] Preferably, the feeding roller 6 has a limiting groove 18 in the middle, and the frame profile is placed in the limiting groove 18. This structure uses the limiting groove 18 to restrict the left and right position of the frame profile, so that the frame profile is not easy to sway left and right during cutting, which further improves the stability and accuracy of cutting.

[0026] Preferably, the cutting table 1 is provided with a sliding rod 19 and a rotating screw 20. The sliding rod 19 is fixed to the cutting table 1 by welding or bolts. The cutting frame 2 is fixed with multiple sliders 21 by welding or bolts. The sliding rod 19 passes through one or more sliders 21 and is slidably connected to them. The screw 20 passes through another slider 21 and is threadedly connected to it. The cutting table 1 is fixed with a reciprocating motor 22 that drives the screw 20 to rotate by welding or bolts. The reciprocating motor 22 drives the screw 20 to rotate, so that the cutting frame 2 and the sliders 21 slide laterally back and forth along the sliding rod 19, making the lateral movement control of the cutting saw blade 3 more convenient and accurate.

[0027] Working Principle: This invention features a cutting frame 2 that slides laterally on a cutting table 1. A cutting saw blade 3 is rotatably connected to the cutting frame 2. The cutting table 1 has a cutting groove 4 that works with the cutting saw blade 3, and a feeding channel 5. This structure allows the frame profile to be placed within the feeding channel 5. The lateral sliding of the cutting frame 2 drives the cutting saw blade 3 to rotate and pass over the frame profile, achieving automatic cutting without requiring manual movement of the cutting saw blade 3. This simplifies the operator's steps, allowing them to stay away from the cutting position. The high-temperature debris generated during cutting is less likely to cause injury to the operator, greatly improving the safety of frame profile cutting. Multiple feeding rollers 6 are rotatably connected to the bottom of the feeding channel 5. The frame profile is placed on the feeding roller 6. The rotation of the feeding roller 6 drives the frame profile to move toward the cutting groove 4, realizing the automatic feeding operation of the frame profile. After the frame profile is in place, the power component drives the pressure plate 7 to slide downward, so that multiple pressure blocks 8 at the bottom of the pressure plate 7 press down to fix the frame profile, realizing the automatic fixation of the frame profile and ensuring the accuracy of cutting. After cutting, the pressure plate 7 slides upward, so that the pressure blocks 8 are separated from the frame profile. The rotation of the feeding roller 6 drives the frame profile to continue to be automatically fed, thus realizing the automatic feeding and fixing of the frame profile. The operator only needs to place the frame profile in the feeding channel 5, which greatly simplifies the operation steps and further improves the overall cutting efficiency.
