Description

Technical Field

[0001] The present invention relates to the technical field of cutting machine equipment, and particularly to a high-precision aluminum profile processing cutting machine. Background Art

[0002] In modern industrial production, aluminum profiles are widely used in many fields such as construction, automotive, aerospace, and electronics due to their characteristics of light weight, high strength, good electrical conductivity, and corrosion resistance. With the continuous development of industrial technology, higher requirements are put forward for the precision and efficiency of aluminum profile processing. Especially in the cutting link, high-precision cutting can not only improve the quality of products, but also reduce material waste and production costs.

[0003] However, in practical applications, traditional aluminum profile processing cutting machines expose many problems that need to be solved urgently. On the one hand, the cutting blade is prone to overheating during long-term continuous operation. This not only accelerates the wear of the blade and shortens its service life, but also leads to a decline in cutting quality and difficulty in ensuring precision, thus affecting the overall quality of the product. On the other hand, there are obvious defects in the safety protection measures of traditional cutting machines. The sharp edge of the cutting blade is often exposed after cutting, lacking effective protection devices, which greatly increases the risk of accidental injury to operators when replacing or handling profiles, bringing serious potential safety hazards to production safety. In addition, the operation process of traditional cutting machines is cumbersome and complex, requiring frequent manual intervention by operators, which not only greatly reduces work efficiency, but also significantly increases labor intensity, making the entire cutting process time-consuming and laborious.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original cutting machine. Summary of the Invention

[0005] The technical solution of the present invention provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single, so as to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: a high-precision aluminum profile processing cutting machine, including a support frame, the middle area at the top of the support frame is connected to a gantry, and a first electric telescopic rod is installed on the top of the gantry, and the end of the first electric telescopic rod is connected to a mounting plate, the bottom of the mounting plate is connected to a protective shell, and a cutting blade is provided in the protective shell, and the cutting blade is connected to a motor device that drives it to rotate and cut, a protection structure for preventing cuts is provided in the protective shell, and a cooling mechanism for dissipating heat from the cutting blade is connected to the protection structure, a fixing frame is installed on the top of the support frame on one side of the gantry, and a limiting structure for fixing the profile is installed on the fixing frame, a movable frame is connected to the top of the support frame on the other side of the gantry, and a positioning structure is installed on the movable frame, and the positioning structure is connected to the limiting structure.

[0007] Preferably, the protective shell is arranged as a fan-shaped hollow structure.

[0008] Preferably, the protection structure includes a movable sleeve, a slider, a chute, a return spring, a connecting rope, and a pulley. There is a movable sleeve on each side inside the protective shell, and two sliders are connected to the outer wall on each end of one end of each movable sleeve, and each slider is engaged and slidably connected to a chute. The chutes are symmetrically opened on both sides of the two end faces of the inner wall of the protective shell, and a return spring is connected between each chute and the slider. A connecting rope is connected to the upward moving slider of each movable sleeve, and the end of the connecting rope penetrates through the top of the protective shell and is connected to the top of the mounting plate, and a pulley for connecting the connecting rope is installed on the inner top of the gantry.

[0009] Preferably, the front view of the movable sleeve is an arc structure, and the side view is a "concave" structure. The inside of the movable sleeve is a hollow structure, and a number of air holes are equidistantly opened on both sides of the inner wall of the movable sleeve.

[0010] Preferably, the cooling mechanism includes a fan device and a bifurcated delivery pipe. The fan device is installed at the bottom of the support frame, and the bifurcated delivery pipe is connected to the fan device, and the bifurcated ends of the bifurcated delivery pipe are each communicated with a movable sleeve.

[0011] Preferably, the limiting structure includes a second electric telescopic rod, a connecting plate, a clamping block, a first piston rod, and a first cylinder. The second electric telescopic rod is installed on the top of the fixing frame, and the end of the second electric telescopic rod is connected to the connecting plate, and the clamping block for limiting the profile is connected to the bottom of the connecting plate. The first piston rod is connected to the top of the connecting plate, and the end of the first piston rod is located inside the first cylinder, and the first cylinder is installed on the fixing frame.

[0012] Preferably, the positioning structure includes a connecting pipe, a second cylinder body, a second piston rod, and a positioning frame. A connecting pipe is connected to the first cylinder body, and the connecting pipe is connected to the second cylinder body, and the second cylinder body is installed on the movable frame. A second piston rod is provided in the second cylinder body, and a positioning frame is connected to the end of the second piston rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In the high-precision aluminum profile cutting machine, during the cutting process, the movable sleeve is precisely pulled open through the synergistic effect of the connecting rope and the pulley, providing the necessary space for the efficient cutting operation of the cutting blade. When the cutting operation is completed, the return spring quickly and powerfully pushes the movable sleeve back to its initial position, forming a tight ring structure that safely wraps the sharp edge serrations of the cutting blade. This unique design effectively prevents the operator from accidentally contacting the cutting blade when replacing or handling the profile, thus significantly improving the safety of the equipment and providing a solid guarantee for the personal safety of the operator.

[0014] The clamping block plays a crucial role in firmly clamping the profile. It can tightly fix the profile, preventing any slight displacement during the cutting process due to vibration or external forces. This stable clamping mechanism not only ensures the smooth progress of the cutting process but also further improves the cutting accuracy, enabling each cut to meet the high-precision process requirements.

[0015] The fan equipment plays a crucial role in heat dissipation. It precisely delivers cold air into the movable sleeve through the bifurcated delivery pipe and directly acts on the cutting blade through the air holes on both sides of the inner wall of the movable sleeve. This efficient heat dissipation design can effectively prevent the cutting blade from overheating due to long-term operation, thereby extending the service life of the blade and ensuring that the stability and cutting accuracy of the cutting process are not affected by high temperature. This design not only improves the reliability and durability of the equipment but also provides strong support for continuous high-precision cutting operations.

[0016] The entire cutting process is highly automated through the collaborative work of the electric telescopic rod and the hydraulic or pneumatic system, greatly reducing manual intervention. This not only improves work efficiency but also reduces the labor intensity of the operator, making the cutting operation easier and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The cooling mechanism 8 includes a fan device 801 and a bifurcated conveying pipe 802. The fan device 801 is installed at the bottom of the support frame 1, and the bifurcated conveying pipe 802 is connected to the fan device 801. The two bifurcated ends of the bifurcated conveying pipe 802 are each communicated with a movable sleeve 701.

[0035] The limiting structure 10 includes a second electric telescopic rod 1001, a connecting plate 1002, a clamping block 1003, a first piston rod 1004, and a first cylinder block 1005. The second electric telescopic rod 1001 is installed at the top of the fixing frame 9, and the connecting plate 1002 is connected to the end of the second electric telescopic rod 1001. The clamping block 1003 for limiting the profile is connected to the bottom of the connecting plate 1002. The first piston rod 1004 is connected to the top of the connecting plate 1002, and the end of the first piston rod 1004 is located inside the first cylinder block 1005. The first cylinder block 1005 is installed on the fixing frame 9.

[0036] The positioning structure 12 includes a connecting pipe 1201, a second cylinder block 1202, a second piston rod 1203, and a positioning frame 1204. The connecting pipe 1201 is connected to the first cylinder block 1005, and the connecting pipe 1201 is connected to the second cylinder block 1202. The second cylinder block 1202 is installed on the movable frame 11. The second piston rod 1203 is arranged inside the second cylinder block 1202, and the positioning frame 1204 is connected to the end of the second piston rod 1203.

[0037] Working principle: As shown in Figure 1 , first place the profile to be cut on the support frame 1 so that the end of the profile fits against the positioning frame 1204 for positioning. Start the second electric telescopic rod 1001 to push the connecting plate 1002 downward, so that the clamping block 1003 at the bottom of the connecting plate 1002 limits and fixes the profile. At the same time, as the connecting plate 1002 moves downward, the first piston rod 1004 is pulled out of the first cylinder block 1005 downward. The hydraulic oil or air in the second cylinder block 1202 is pumped into the first cylinder block 1005 through the connecting pipe 1201, so that the second piston rod 1203 drives the positioning frame 1204 to move into the second cylinder block 1202;

[0038] Start the first electric telescopic rod 3 to push the mounting plate 4 and the protective shell 5 downward. At the same time, start the cutting blade 6 in the protective shell 5 to rotate for subsequent cutting of the profile. During the downward movement of the mounting plate 4 and the protective shell 5, through the cooperation of the connecting rope 705 and the pulley 706, and the limitation of the slider 702 and the chute 703, the movable sleeve 701 will be pulled to move toward both sides inside the protective shell 5, and the return spring 704 is compressed under force, so that the movable sleeve 701 is disengaged from the shielding protection of the cutting blade 6, facilitating the subsequent cutting of the profile by the cutting blade 6;

[0039] After the cutting is completed, conversely as described above, start the first electric telescopic rod 3 to drive the mounting plate 4 and the protective shell 5 to move upward. The return spring 704 is released from restraint, pushing the slider 702 to move and reset within the chute 703. The slider 702 drives the movable sleeve 701 out of the protective shell 5. The ends of the two movable sleeves 701 come into contact with each other. Cooperating with the protective shell 5, they form an annular structure that can wrap the serrations on the edge of the cutting blade 6 to avoid cutting fingers. At this time, the blower device 801 is started, and cold air is conveyed through the bifurcated delivery pipe 802 into the two movable sleeves 701. Through the air holes on both sides of the inner walls of the two movable sleeves 701, it acts on the cutting blade 6 to cool and dissipate heat from the cutting blade 6, avoiding overheating of the cutting blade 6 during long-term operation, which may affect the cutting performance and cutting accuracy;

[0040] Then control the second electric telescopic rod 1001 to drive the connecting plate 1002 and the clamping block 1003 to move upward and reset, disengaging the clamping of the profile to facilitate the movement of the profile. During this process, the upward reset of the connecting plate 1002 pushes the first piston rod 1004 to move into the first cylinder body 1005, causing the hydraulic oil or air in the first cylinder body 1005 to flow back into the second cylinder body 1202 through the connecting pipe 1201, pushing the second piston rod 1203 in the second cylinder body 1202 to move downward, causing the positioning frame 1204 to reset, facilitating positioning when the profile moves, which is beneficial to improving the cutting accuracy of the profile. This is the working principle of this high-precision aluminum profile processing cutting machine.
