Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile processing and cutting, and more specifically, to an aluminum profile cutting machine based on clamping fixation. Background Art

[0002] During the production of aluminum alloy doors and windows, workers need to cut aluminum profiles so that the cut aluminum profiles are suitable for assembling aluminum alloy doors and windows. When processing in a factory, only machines are needed for cutting. However, for small stores, workers mostly use cutting machines to cut aluminum profiles. When cutting, workers place the aluminum profile on the cutting machine, then manually position the aluminum profile, and after positioning is completed, use the cutting machine to cut the aluminum profile, thus completing the cutting of the aluminum profile.

[0003] However, when workers cut aluminum profiles, one hand positions the aluminum profile and the other hand controls the cutting machine to cut the aluminum profile. When the cutting machine cuts the aluminum profile, the cutting blade on the cutting machine will drive the aluminum profile to vibrate, causing the aluminum profile to be unstable during placement, reducing the cutting accuracy of the aluminum profile. At the same time, when positioning one end of the aluminum profile, when the aluminum profile is about to be cut and broken, the method of positioning one end of the aluminum profile cannot position the other end of the aluminum profile. At this time, the unpositioned end of the aluminum profile is easily driven by the cutting blade to shake, making the cutting blade prone to cutting the aluminum profile obliquely. When manually positioning the aluminum profile, the cutting blade is relatively close to the worker's hand, there is a risk that the cutting blade will touch the worker's hand, which is likely to cause harm to the worker. Therefore, an aluminum profile cutting machine is needed that can actively position the aluminum profile during cutting and is also convenient for cutting the aluminum profile. Summary of the Invention

[0004] The purpose of the present invention is to provide an aluminum profile cutting machine based on clamping fixation to solve the problems raised in the above background art.

[0005] To achieve the above purpose, an aluminum profile cutting machine based on clamping fixation is provided, including a cutting base. A positioning mechanism is arranged on the upper side of the cutting base, and a cutting mechanism is installed on the positioning mechanism. The positioning mechanism drives the cutting mechanism to cut the aluminum profile. Before the positioning mechanism drives the cutting mechanism to cut the aluminum profile, the cutting base conducts preliminary positioning on the aluminum profile. During the process of the positioning mechanism driving the cutting mechanism to approach the aluminum profile, the positioning mechanism squeezes the part of the cutting base where the aluminum profile is preliminarily positioned. During the process of the cutting mechanism cutting the aluminum profile, the positioning mechanism squeezes the aluminum profile. As one end of the positioning mechanism continuously approaches the cutting base, the squeezing force of the part of the cutting base where the aluminum profile is positioned and the positioning mechanism on the aluminum profile continuously increases.

[0006] As a further improvement of the present technical solution, the cutting seat includes a base and a support column fixed to the upper side of the base near one end. Fixed columns are fixedly connected to both sides of the support column. A U-shaped pressing frame is arranged on one side of the support column. The two ends of the pressing frame are respectively hinged to one end of the fixed column. A stop bar is fixed to the upper side of the base at the end far from the support column. The stop bar blocks the aluminum profile to be cut, and the pressing frame presses the upper side of the aluminum profile blocked by the stop bar.

[0007] As a further improvement of the present technical solution, the positioning mechanism includes a flipping member and a positioning member arranged on the lower side of the flipping member. The cutting mechanism is installed on the flipping member. When the flipping member drives the cutting mechanism to approach the aluminum profile, the positioning member first presses the pressing frame. When the cutting mechanism cuts the aluminum profile, the positioning member presses the aluminum profile.

[0008] As a further improvement of the present technical solution, the flipping member includes a flipping rod. The middle position of the flipping rod is hinged to the upper end of the support column. An upward-flipping spring is hooked at one end of the flipping rod close to the support column. The upward-flipping spring is arranged on the side of the support column far from the base, and the other end of the upward-flipping spring is hooked to the bottom of the support column. The upward-flipping spring pulls the end of the flipping rod far from the upward-flipping spring to flip upward, and a grip rod is fixed to the end of the flipping rod far from the upward-flipping spring.

[0009] As a further improvement of the present technical solution, the cutting mechanism includes a cutting head rotatably connected to the end of the flipping rod far from the upward-flipping spring. A driving motor is installed on the upper side of the hinged position between the flipping rod and the support column. The driving motor and the cutting head are connected by a transmission member. The driving motor drives the transmission member to drive the cutting head to rotate.

[0010] As a further improvement of the present technical solution, the positioning member includes two elastic steel bars. The two elastic steel bars are arranged on both sides of the cutting head. An installation rod is fixed to the side wall of the flipping rod between the driving motor and the cutting head. Clamping plates are fixed to both ends of the installation rod. One end of the elastic steel bar is inserted between the clamping plate and the installation rod, and the elastic steel bar is fixed between the clamping plate and the installation rod with screws.

[0011] As a further improvement of the present technical solution, sliding grooves are symmetrically opened on the upper side of the pressing frame from left to right. A clamping cavity is arranged at the end of the sliding groove far from the fixed column. When the cutting head flips downward, one end of the elastic steel bar is inserted into the sliding groove and slides along the track of the sliding groove. During the movement of the elastic steel bar in the sliding groove, the elastic steel bar presses the pressing frame downward, so that the pressing frame presses the aluminum profile blocked by the stop bar. The greater the distance that the flipping rod flips downward, the greater the pressing force of the elastic steel bar on the pressing frame.

[0012] As a further improvement of the technical solution, extension blocks are fixed at positions near both ends of the mounting rod. A hinge frame is arranged between the two elastic steel bars. The hinge frame is arranged on both sides of the cutting machine head. The hinge frame is fixed to the lower side of the extension block by screws, and a pressure rod is hinged to the lower end of the hinge frame. One end of the pressure rod is arranged above the stop bar.

[0013] As a further improvement of the technical solution, the other end of the pressure rod is fixed with an extension rod. A pressure rod spring is connected between one end of the extension rod and the lower side wall of the mounting rod. The pressure rod spring pulls one end of the extension rod upward, so that one end of the pressure rod turns downward to press the aluminum profile blocked by the stop bar. And as the cutting machine head continuously moves downward, the pressure of the pressure rod on the aluminum profile also continuously increases.

[0014] As a further improvement of the technical solution, during the process of the cutting machine head turning downward, one end of the elastic steel bar first inserts into the sliding groove, so that the elastic steel bar presses the pressure frame. When the cutting machine head cuts the aluminum profile, the pressure rod presses the aluminum profile. And during the process of the cutting machine head continuously moving downward, the pressure frame and the pressure rod increase the pressing force on the aluminum profile.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this aluminum profile cutting machine based on clamping fixation, when placing the aluminum profile, only need to place the aluminum profile on one side of the stop bar and then press the pressure frame on the aluminum profile. Before the cutting machine head cuts the aluminum profile, the elastic steel bar presses the pressure frame, so that the aluminum profile is positioned on the stop bar by the pressure frame, eliminating the trouble of workers positioning the aluminum profile by hand. At the same time, by pressing the aluminum profile with the pressure frame, the positioning speed of the device for the aluminum profile is accelerated, and then the cutting speed of the workers for the aluminum profile is accelerated.

[0017] In this aluminum profile cutting machine based on clamping fixation, when the cutting machine head cuts the aluminum profile, the pressure rod presses on both sides of the position where the cutting machine head cuts the aluminum profile, improving the stability of the aluminum profile on the stop bar, so that when the cutting machine head cuts the aluminum profile, the situation that the aluminum profile deviates due to vibration can be avoided, and the cutting accuracy of the device for the aluminum profile is improved.

[0018] In this aluminum profile cutting machine based on clamping fixation, during the process of the cutting machine head cutting the aluminum profile, as the cutting machine head continuously moves downward, the pressing force of the elastic steel bar on the pressure frame and the pressing force of the pressure rod on the aluminum profile continuously increase. When the aluminum profile is about to be cut and broken by the cutting machine head, the pressure frame cooperates with the two pressure rods to perform four-point pressing on the aluminum profile, so that the ends of the aluminum profile that is about to be cut into two sections are both pressed and positioned, ensuring that the aluminum profile will not shake and tilt when it is about to be cut off, and then ensuring the accurate cutting of the aluminum profile. At the same time, using the positioning mechanism to press the aluminum profile eliminates the need for workers to position the aluminum profile, improving the safety of workers cutting the aluminum profile.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Example 1

[0035] Please refer to Figure 1 - Figure 2 As shown in the figure, the purpose of this embodiment is to provide an aluminum profile cutting machine based on clamping fixation, including a cutting seat 1. A positioning mechanism 2 is arranged on the upper side of the cutting seat 1, and a cutting mechanism is installed on the positioning mechanism 2. The aluminum profile is placed on the cutting seat 1. Workers perform hand positioning on the aluminum profile placed on the cutting seat 1, or clamp the aluminum profile through a rotating clamping plate to fix the position of the aluminum profile, and then drive the cutting mechanism to cut the aluminum profile through the positioning mechanism 2. However, in order to quickly position the aluminum alloy and quickly cut and disconnect the aluminum alloy, when workers cut the aluminum profile, they will use one hand to position the aluminum profile and the other hand to control the cutting machine to cut the aluminum profile. When the cutting machine cuts the aluminum profile, the cutting disc on the cutting machine will drive the aluminum profile to vibrate, resulting in unstable placement of the aluminum profile, reducing the cutting accuracy of the aluminum profile. At the same time, when positioning one end of the aluminum profile, when the aluminum profile is about to be cut and broken, the method of positioning one end of the aluminum profile cannot position the other end of the aluminum profile. At this time, the unpositioned end of the aluminum profile is easily driven to shake by the cutting disc, making the cutting disc prone to cutting the aluminum profile obliquely. When using the hand to position the aluminum profile, the distance between the cutting disc and the worker's hand is relatively close, there is a risk that the cutting disc will touch the worker's hand, and it is easy to cause harm to the worker.

[0036] In order to speed up the positioning of the aluminum profile, ensure the cutting accuracy of the aluminum profile, and improve the safety of workers when using the device, the improvement of the present invention lies in: before the positioning mechanism 2 drives the cutting mechanism to cut the aluminum profile, the cutting seat 1 performs preliminary positioning on the aluminum profile. During the process of the positioning mechanism 2 driving the cutting mechanism to approach the aluminum profile, the positioning mechanism 2 squeezes the part of the cutting seat 1 that preliminarily positions the aluminum profile, so that the aluminum profile is preliminarily positioned. During the process of the cutting mechanism cutting the aluminum profile, the positioning mechanism 2 squeezes the aluminum profile, so that the aluminum profile is fixed at multiple points by the cutting seat 1 and the positioning mechanism 2, ensuring that the aluminum profile will not shake when being cut. As one end of the positioning mechanism 2 continuously approaches the cutting seat 1, the squeezing force of the part of the cutting seat 1 that positions the aluminum profile and the positioning mechanism 2 on the aluminum profile continuously increases, so that the aluminum profile is stably fixed by the cutting seat 1 and the positioning mechanism 2. When the cutting mechanism is about to cut off the aluminum profile, the aluminum profile will not shake, ensuring the cutting accuracy of the aluminum profile. At the same time, through the positioning of the aluminum profile by the cutting seat 1 and the positioning mechanism 2, the need for workers to press the aluminum profile is eliminated, thus improving the safety of workers cutting the aluminum profile.

[0037] The structures of the cutting seat 1 and the positioning mechanism 2 are refined as follows. Please refer to Figure 1 - Figure 8As shown in the figure, the cutting seat 1 includes a base 11 and a support column 12 fixed to the upper side of the base 11 near one end. Fixed columns 15 are fixedly connected to both sides of the support column 12. A U-shaped pressing frame 13 is arranged on one side of the support column 12. Both ends of the pressing frame 13 are respectively hinged to one end of the fixed column 15, so that the pressing frame 13 can rotate around the position hinged to the fixed column 15. A stop bar 14 is fixed to the upper side of the base 11 away from the support column 12. The stop bar 14 blocks the aluminum profile to be cut, restricting the placement position of the aluminum profile on the base 11. At the same time, the pressing frame 13 presses the upper side of the aluminum profile blocked by the stop bar 14, so that the aluminum profile is preliminarily positioned.

[0038] At the same time, the positioning mechanism 2 includes a flipping member 21 and a positioning member 22 arranged on the lower side of the flipping member 21. The cutting mechanism is installed on the flipping member 21. During the process of the flipping member 21 driving the cutting mechanism to approach the aluminum profile, the positioning member 22 first presses the pressing frame 13. When the cutting mechanism cuts the aluminum profile, the positioning member 22 presses the aluminum profile.

[0039] Among them, the flipping member 21 includes a flipping rod 211. The middle position of the flipping rod 211 is hinged to the upper end of the support column 12. An upward-flipping spring 216 is hooked at one end of the flipping rod 211 close to the support column 12. The upward-flipping spring 216 is arranged on the side of the support column 12 away from the base 11, and the other end of the upward-flipping spring 216 is hooked to the bottom of the support column 12. The upward-flipping spring 216 pulls the end of the flipping rod 211 away from the upward-flipping spring 216 to flip upward. In this way, when the device is not in use, through the pulling of the upward-flipping spring 216 on the flipping rod 211, the flipping rod 211 flips upward, so that one end of the flipping rod 211 is lifted upward, facilitating the worker to place the aluminum profile on the base 11.

[0040] A grip rod 212 is fixed to the end of the flipping rod 211 away from the upward-flipping spring 216. The worker pulls the grip rod 212 by holding the grip rod 212, so that the grip rod 212 drives the flipping rod 211 to rotate around the position where the flipping rod 211 is hinged to the support column 12.

[0041] The cutting mechanism includes a cutting head 3 rotatably connected to the end of the flipping rod 211 away from the upward-flipping spring 216. The stop bar 14 is arranged on the side of the lowest position of the cutting head 3 away from the support column 12. When the cutting head 3 cuts the aluminum profile blocked by the stop bar 14, the aluminum profile will not be carried away by the friction force generated by the cutting of the cutting head 3. At the same time, a driving motor 5 is installed above the hinged position of the flipping rod 211 and the support column 12. The driving motor 5 is connected to the cutting head 3 through a transmission member 4. The driving motor 5 drives the transmission member 4, so that the transmission member 4 drives the cutting head 3 to rotate.

[0042] By pressing down the grip rod 212, the flipping rod 211 drives the cutting head 3 closer to the aluminum profile, and the cutting head 3 cuts the aluminum profile. During the process of the grip rod 212 driving the cutting head 3 to move downward, the positioning member 22 presses the pressing frame 13, so that the pressing frame 13 preliminarily positions the aluminum profile on one side of the retaining strip 14. By positioning the aluminum profile through the pressing frame 13, it replaces the positioning effect of the worker's hand on the aluminum profile and improves the safety of aluminum profile cutting.

[0043] Among them, the positioning member 22 includes two elastic steel strips 224. The two elastic steel strips 224 are arranged on both sides of the cutting head 3. An installation rod 213 is fixed on the side wall between the driving motor 5 and the cutting head 3 of the flipping rod 211. Clamping plates 217 are fixed at both ends of the installation rod 213. One end of the elastic steel strip 224 is inserted between the clamping plate 217 and the installation rod 213, and the elastic steel strip 224 is fixed between the clamping plate 217 and the installation rod 213 with screws, so that the elastic steel strip 224 is fixed under the installation rod 213. When the elastic steel strip 224 does not contact the pressing frame 13, the elastic steel strip 224 is inclined and arranged under the installation rod 213, and the inclined direction is set towards the direction close to the cutting head 3. When the grip rod 212 moves downward, one end of the elastic steel strip 224 contacts the pressing frame 13, and as the grip rod 212 continues to move downward, the elastic steel strip 224 presses the pressing frame 13, so that the pressing frame 13 presses the aluminum profile blocked by the retaining strip 14, and the aluminum profile is fixed on one side of the retaining strip 14 through the pressing of the pressing frame 13.

[0044] In order to ensure that the elastic steel strip 224 can accurately press the pressing frame 13, sliding grooves 16 are symmetrically opened on the upper side of the pressing frame 13. When the cutting head 3 rotates downward, one end of the elastic steel strip 224 is inserted into the sliding groove 16 and slides along the track of the sliding groove 16. During the movement of the elastic steel strip 224 in the sliding groove 16, it presses the pressing frame 13 downward, so that the pressing frame 13 presses the aluminum profile blocked by the retaining strip 14. The greater the downward rotation distance of the flipping rod 211, the greater the pressing force of the elastic steel strip 224 on the pressing frame 13. At the same time, in order to prevent the elastic steel strip 224 from sliding out of the sliding groove 16 when pressing the pressing frame 13, a clamping cavity is arranged at one end of the sliding groove 16 away from the fixed column 15. One end of the elastic steel strip 224 is inserted into the clamping cavity, and the clamping cavity restricts one end of the elastic steel strip 224 to ensure that the elastic steel strip 224 can be stably placed in the sliding groove 16.

[0045] In order to improve the pressing effect of the elastic steel strip 224 on the pressing frame 13, a leg 225 is fixed on one side of the elastic steel strip 224. During the process of the elastic steel strip 224 pressing the pressing frame 13, one end of the leg 225 enters the chute 16, so that the elastic steel strip 224 presses the pressing frame 13 through the leg 225, thereby forming the pressing effect of the elastic steel strip 224 on both ends of the pressing frame 13 and improving the pressing effect of the elastic steel strip 224 on the pressing frame 13.

[0046] During the downward movement of the grip rod 212, the elastic steel strip 224 continuously increases the pressing force on the pressing frame 13, so that the aluminum profile is stably fixed on one side of the retaining strip 14. When the cutting head 3 cuts the aluminum profile, the aluminum profile will vibrate. The pressing frame 13 pressing the aluminum profile positions the aluminum profile. However, when the aluminum profile is about to be cut and broken, at this time the aluminum profile is about to be cut into two parts, and the position where the aluminum profile is cut will shake because the two parts of the aluminum profile are about to separate. Simply pressing the aluminum profile by the pressing frame 13 cannot stably position the aluminum profile, and at this time the aluminum profile is easily driven by the cutting head 3 to shake.

[0047] Embodiment 2

[0048] In order to ensure that the aluminum profile is accurately cut, extension blocks 214 are fixed at positions near both ends of the mounting rod 213. A hinge frame 221 is arranged between the two elastic steel strips 224. The hinge frame 221 is arranged on both sides of the cutting head 3. The hinge frame 221 is fixed to the lower side of the extension block 214 by screws, and a pressure rod 222 is hinged to the lower end of the hinge frame 221. One end of the pressure rod 222 is arranged on the upper side of the retaining strip 14, and an extension rod 223 is fixed to the other end of the pressure rod 222. A pressure rod spring 215 is connected between one end of the extension rod 223 and the lower side wall of the mounting rod 213. The pressure rod spring 215 pulls one end of the extension rod 223 upward, so that one end of the pressure rod 222 turns downward to press the aluminum profile blocked by the retaining strip 14. And as the cutting head 3 continuously moves downward, the pressure of the pressure rod 222 on the aluminum profile also continuously increases, so that the pressure rod 222 stably presses and positions the end of the aluminum profile about to be cut, ensuring that when the aluminum profile is cut, the aluminum profile will not move in position and ensuring that the aluminum profile is accurately cut.

[0049] During the downward turning of the cutting head 3, one end of the elastic steel strip 224 first inserts into the chute 16, so that the elastic steel strip 224 presses the pressing frame 13. At this time, the pressing of the pressing frame 13 completes the preliminary positioning of the aluminum profile. When the cutting head 3 is about to contact the aluminum profile, the pressure rod 222 presses the aluminum profile and presses both sides of the position where the aluminum profile is about to be cut. During the continuous downward movement of the cutting head 3, the pressing frame 13 and the pressure rod 222 increase the pressing force on the aluminum profile to ensure that the aluminum profile will not move during cutting and ensure that the aluminum profile is accurately cut.

[0050] During the process of the cutting machine head 3 cutting the aluminum profile, as the cutting machine head 3 continuously moves downward, the pressing force of the elastic steel strip 224 on the pressing frame 13 and the pressing force of the pressing rod 222 on the aluminum profile continuously increase. When the aluminum profile is about to be cut and broken by the cutting machine head 3, the pressing frame 13 cooperates with the two pressing rods 222 to perform four-point pressing on the aluminum profile, so that the ends of the aluminum profile that are about to be cut into two sections are both pressed and positioned, ensuring that the aluminum profile will not shake and tilt when it is about to be cut off, thereby ensuring the accurate cutting of the aluminum profile. At the same time, the positioning mechanism 2 is used to press the aluminum profile, eliminating the need for workers to position the aluminum profile and improving the safety of workers cutting the aluminum profile.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
