Technical Field

[0001] This utility model relates to the field of profile processing equipment, and in particular to a high-quality profile cutting device. Background Technology

[0002] As an important industrial material, profiles have an extremely wide range of applications, covering multiple fields such as construction and industry. In the construction field, profiles are widely used in door and window frames, curtain wall structures, and interior and exterior decorative materials, providing important support for the aesthetics and practicality of modern buildings. In the industrial field, their uses are even more diverse. For example, in the solar energy industry, profiles are used to manufacture solar panel frames, ensuring the stable installation and efficient operation of solar panels. In the automotive manufacturing field, especially in the lightweight design of new energy vehicles, aluminum profiles, due to their light weight, high strength, and corrosion resistance, are widely used in key components such as door sill beams, effectively reducing vehicle weight, improving energy efficiency, and enhancing vehicle range.

[0003] Profiles typically originate from long raw materials. To meet the specific needs of different users, they must be processed into specific lengths through precise cutting techniques. In this process, cutting quality and efficiency are key indicators for evaluating the performance of profile cutting equipment. However, most profile cutting equipment currently on the market uses a single-section cutting method, which has a significant efficiency bottleneck in actual operation and is difficult to meet the needs of large-scale production. Furthermore, these devices face numerous problems during the cutting process, such as inaccurate profile positioning and cutting debris interfering with the cutting tool. These problems lead to unstable cutting quality, thus affecting the final performance of the profile.

[0004] In view of the above situation, there is an urgent need to develop a high-quality profile cutting device to effectively solve the problems of low efficiency and unstable cutting quality in the existing technology. Utility Model Content

[0032] The following is a preferred embodiment of a high-quality profile cutting device provided by this utility model that can solve the above-mentioned technical problems.

[0033] Please refer to Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of the structure of the high-quality profile cutting device of this utility model. Figure 2 This is a schematic diagram of the cutting mechanism and cutting platform in this utility model.

[0034] In the diagram, units with similar structures are represented by the same labels.

[0035] This embodiment provides a detailed description of a high-quality profile cutting device: A high-quality profile cutting device is used to cut the profiles provided by the profile feeding device 1. The high-quality profile cutting device includes a cutting and feeding robot 11, a cutting platform 12, and a cutting mechanism 13.

[0036] A profile feeding device is located at one end of the cutting platform 12. A cutting and feeding robot 11 is movably mounted on the mounting beam 111, above the profile feeding device 1 and the cutting platform 12. The cutting and feeding robot 11 picks up multiple profiles 5 from the profile feeding device and transports them to the cutting platform 12. Two sets of cutting mechanisms 13 are located at both ends on one side of the cutting platform 12, and the cutting mechanisms 13 are used to cut the profiles. A material distribution and conveying mechanism 14 can also be set on the other side of the cutting platform 12. The material distribution and conveying mechanism 14 is used to remove the cut profiles 5 from the cutting platform 12 and transport them separately.

[0037] Please refer to Figure 2 The cutting platform 12 includes a sliding seat 136 and a cutting positioning assembly disposed on the sliding seat 136 for fixing the profile. The cutting positioning assembly includes a lateral fixed positioning block 121, a lateral movable positioning block 122, a lateral drive cylinder 125, a bottom movable positioning block 123, a bottom drive mechanism 127, a top movable positioning block 124, and a top drive mechanism 126.

[0038] The lateral movable positioning block 122 is connected to the output end of the lateral drive cylinder 125. Multiple profiles 5 are positioned side by side between the lateral movable positioning block 122 and the lateral fixed positioning block 121. The lateral movable positioning block 122 moves and cooperates with the lateral fixed positioning block 121 to perform lateral clamping and positioning of a set number of profiles. In this embodiment, the cutting positioning assembly can hold four profiles, and the four profiles are in surface contact and are clamped and positioned together between the lateral movable positioning block 122 and the lateral fixed positioning block 121.

[0039] Multiple bottom movable positioning blocks 123 are connected one-to-one with the output ends of multiple bottom drive mechanisms 127. Each bottom movable positioning block 123 is in positioning contact with one profile 5. The top movable positioning block 124 is connected to the output end of the top drive mechanism 126 and is in positioning contact with multiple profiles 5. The bottom movable positioning blocks 123, in conjunction with the top movable positioning blocks 124, can vertically clamp and position a set number of profiles 5.

[0040] Please refer to Figure 3In this embodiment, the bottom drive mechanism 127 includes a bottom drive cylinder 1271, a rotation drive rod 1272, and a support base 1273. The rotation drive rod 1272 is rotatably connected to the support base 1273 around the rotation column 12731. The two ends of the rotation drive rod 1272 are respectively rotatably connected to the bottom movable positioning block 123 and the output end of the bottom drive cylinder 1271. The rotation column 12731 is located between the bottom movable positioning block 123 and the bottom drive cylinder 1271.

[0041] Please refer to Figure 4 and Figure 5 The top drive mechanism 126 includes a fixed frame 1261, a lifting frame 1262, a motor, a limit bar 1263, a crank block 1264, and a drive wheel 1265.

[0042] The lifting frame 1262 is slidably connected to the fixed frame 1261. Two limit bars 1263 are arranged in parallel on the side of the lifting frame 1262 near the fixed frame 1261. The motor is fixedly connected to the fixed frame 1261. The crank block 1264 is located between the fixed frame 1261 and the lifting frame 1262. One end of the crank block 1264 is connected to the output shaft of the motor, and the other end of the crank block 1264 is connected to the drive wheel 1265. The drive wheel 1265 is fitted between the two limit bars 1263. The top movable positioning block 124 is connected to the bottom of the lifting frame 1262.

[0043] The motor can drive the crank block 1264 to rotate, thereby controlling the lifting and lowering of the top movable positioning block 124. The motor is preferably a servo motor, which has high control precision and can accurately control the lifting frame 1262 to lift and lower to any height position.

[0044] In order to reduce the size of the top drive mechanism 126 and reduce costs, the distance from the rotation center of the crank block 1264 to one side of the fixed frame 1261 can be set to be greater than the length of the crank block 1264, while the distance from the rotation center of the crank block 1264 to the other side of the fixed frame 1261 is less than the length of the crank block 1264. In this way, when the lifting frame 1262 is lifted, the crank block 1264 does not need to rotate a full circle to achieve the maximum lifting stroke.

[0045] Please refer to Figure 3Furthermore, in this embodiment, the bottom movable positioning block 123 includes a positioning connecting block 1231 and a positioning main block 1232. The positioning main block 1232 is disposed on the top surface of the positioning connecting block 1231, thus facilitating the positioning of profiles 5 of different specifications by replacing different positioning main blocks 1232. The bottom of the positioning connecting block 1231 is rotatably connected to the rotation drive rod 1272, and a limit groove 12311 is provided at the bottom of the positioning connecting block 1231. The rotation drive rod 1272 slides within the limit groove 12311. This improves the stability of the rotation drive rod 1272 driving the connecting block 1231.

[0046] Please refer to Figure 3 Furthermore, both ends of the top surface of the positioning main block 1232 are provided with support bosses 12321. The support bosses 12321 are used to support the profile. The support bosses 12321 have a small area and are dispersed in position, which can not only position the profile 5 well, but also reduce the probability of cutting debris falling onto the support bosses 12321.

[0047] Please refer to Figure 3 In this embodiment, multiple support seats 1273 are slidably and adjustablely mounted on a fixed rod 1274, and the fixed rod 1274 is fixedly connected to a sliding seat 136. Multiple bottom drive cylinders 1271 are slidably and adjustablely mounted on a fixed plate 1275, and the fixed plate 1275 is fixedly connected to a sliding seat 136. By adjusting the positions of the support seats 1273 and the bottom drive cylinders 1271, it can be used to support and position profiles 5 of different sizes and models.

[0048] Understandably, screws can be installed on the support base 1273 to press against the fixing rod 1274, thereby achieving a sliding and adjustable connection between the support base 1273 and the fixing rod 1274. An elongated groove can be provided on the fixing plate 1275, through which screws pass to be fixedly connected to the bottom drive cylinder 1271, thereby achieving a sliding and adjustable connection between the bottom drive cylinder 1271 and the fixing plate 1275.

[0049] Please refer to Figure 3 In this embodiment, a roller 1276 is provided on the side of the rotating drive rod 1272 near the top movable positioning block 124. The roller 1276 is located between the rotating column 12731 and the bottom drive cylinder 1271.

[0050] The output end of the bottom drive cylinder 1271 includes a clamping position and a standby position. When the output end of the bottom drive cylinder 1271 is in the clamping position, the bottom movable positioning block 123 is driven to rise to contact and position with the profile 5, while the roller 1276 is at a set distance from the profile 5. At this time, the distance between the bottom movable positioning block 123 and the top movable positioning block 124 is less than the distance between the roller 1276 and the top movable positioning block 124.

[0051] When the output end of the bottom drive cylinder 1271 is in the standby position, the bottom movable positioning block 123 is driven to descend, and the roller 1276 can contact the profile 5. The bottom movable positioning block 123 will be at a set distance from the profile 5. At this time, the distance between the roller 1276 and the top movable positioning block 124 is less than the distance between the bottom movable positioning block 123 and the top movable positioning block 124. The roller 1276 is located at a higher position than the bottom movable positioning block 123, so the roller 1276 can support the profile 5 grasped and conveyed by the cutting and feeding robot 11. During the process of the bottom movable positioning block 123 rising and contacting the profile 5, the roller 1276 can continuously support the profile 5, which can improve the positioning stability and accuracy of the cutting and positioning component for the profile 5.

[0052] In this embodiment, multiple bottom movable positioning blocks 123 are opposite to a top movable positioning block 124. The bottom surface of the top movable positioning block 124 is provided with multiple strip grooves 1241. The extension direction of the strip grooves 1241 is perpendicular to the length direction of the profile on the bottom movable positioning block 123, which can improve the pressing and fixing effect.

[0053] The bottom surface of the top movable positioning block 124 is provided with multiple air holes 1242, which are connected to corresponding air blowing devices. Air holes 1242 are provided both inside the strip groove 1241 and on the bottom surface of the top movable positioning block 124. The air holes 1242 can blow away debris on the bottom movable positioning block 123, and the reverse airflow can also clean the bottom surface of the top movable positioning block 124, thereby improving the stability and accuracy of the pressing and fixing position.

[0054] Please refer to Figures 6-8 In this embodiment, the cutting mechanism 13 also includes a cutting fixing seat 131, a cutting drive component 132, a blade 133, a dust suction cover 134, and a sealing plate 135.

[0055] The cutting drive 132 is slidably connected to the cutting fixed base 131, the blade 133 is connected to the output end of the cutting drive 132, and the dust collection hood 134 is fixedly connected to the cutting fixed base 131. The dust collection hood 134 includes an upper cover plate and a lower cover plate. The blade 133 is located between the upper cover plate and the lower cover plate. One end of the blade 133 extends out of the dust collection hood 134, and the dust collection hood 134 forms a dust collection port 1341 at the position where the blade 133 extends out, which can suck away cutting debris and improve the positioning environment of the subsequent profile.

[0056] A clearance groove 1342 for the movement of the cutting drive component 132 is provided through the lower cover plate. One end of the sealing plate 135 is connected to the side of the cutting drive component 132 away from the suction port 1341. The sealing plate 135 and the lower cover plate are stacked and slidably arranged, and the sealing plate 135 closes the clearance groove 1342. During the movement of the cutting drive component 132, the airflow will not be diverted by the clearance groove 1342, so that the suction port 1341 maintains a high suction force.

[0057] The recess 1342 penetrates the end face of the lower cover plate near the cutting platform 12. The side of the blade 133 near the upper cover plate is provided with a locking member 1321. The locking member 1321 is used to fix the blade 133 to the output end of the cutting drive member 132. The upper cover plate is provided with a groove 1343 for avoiding the locking member 1321. The groove 1343 penetrates the end face of the upper cover plate near the cutting platform 12, which can appropriately increase the dust collection area of ​​the dust collection port 1341.

[0058] Please refer to Figure 9 Furthermore, the cutting fixing seat 131 is rotatably disposed inside the sliding seat 136 about the first axis 1311, and the first axis 1311 is parallel to the blade 133.

[0059] A nut 137 is rotatably mounted on the sliding seat 136 around a second axis. An adjusting screw 138 is internally threaded onto the nut 137. The adjusting screw 138 is perpendicular to the first axis 1311. One end of the adjusting screw 138 is rotatably connected to the cutting fixture 131 around a third axis. The adjusting screw 138 and the cutting fixture 131 can be connected by a spherical structure to form a universal rotatable connection. The first axis 1311, the second axis, and the third axis are parallel. Rotating the adjusting screw 138 drives the fixture 131 to rotate around the first axis 1311, thereby adjusting the angle at which the blade 133 cuts the profile.

[0060] Limiting posts 1312 are provided on both sides of the cutting fixture 131. The limiting posts 1312 are parallel to the first axis 1311. The limiting posts 1312 extend through to the outer side of the sliding seat 136 and are fixedly connected to a locking block 139. The locking block 139 is provided with an elongated hole for fixed connection with the sliding seat 136. The locking block 139 can be fixedly connected to the sliding seat 136 by means of screw connection. Tightening the screw can fix the locking block 139 to the sliding seat 136, thereby locking the position of the cutting fixture 131.

[0061] The outer surface of the sliding base 136 is provided with a scale bar 13A, and the locking block 139 is provided with an indicator needle that cooperates with the scale bar 13A. The indicator needle and the scale bar 13A can be used to provide feedback on the cutting angle of the blade 133.

[0062] The high-quality profile cutting device of this embodiment uses a cutting positioning assembly consisting of a lateral fixed positioning block 121, a lateral movable positioning block 122, a bottom movable positioning block 123, and a top movable positioning block 124 to effectively press and position multiple profiles. The cutting mechanism 13 can efficiently cut multiple profiles simultaneously. Furthermore, the combination of the dust suction hood 134 and the sealing plate 135 allows for concentrated, high-suction removal of cutting debris from the blade, reducing interference from debris on the profile pressing and positioning, and improving cutting quality.

[0063] The working principle of the high-quality profile cutting device in this embodiment is as follows: the cutting and feeding robot 11 grabs multiple profiles from the profile feeding device and transports them to two sets of cutting and positioning components. The lateral movable positioning block 122 moves and cooperates with the lateral fixed positioning block 121 to perform lateral clamping and positioning of a set number of profiles. The bottom movable positioning block 123 cooperates with the top movable positioning block 124 to perform vertical clamping and positioning of a set number of profiles 5.

[0064] After the profile is clamped and positioned, the cutting drive 132 slides to drive the blade 133 to feed and cut. At the same time, the dust suction port 1341 can suck away cutting debris and dust.

[0065] After cutting is completed, the cutting positioning component releases the profile, and the material conveying mechanism 14 rises to pick up the multiple profiles on the cutting platform 12 for unloading.

[0066] This completes the process of cutting profiles using the high-quality profile cutting device of this embodiment.

[0067] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
