Description

Technical Field

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

[0002] In the process of making aluminum alloy doors and windows, workers need to cut aluminum profiles to make the cut aluminum profiles suitable for assembling aluminum alloy doors and windows. When aluminum alloy doors and windows are processed in the factory, they only need to be cut by machines, but for small stores, workers mostly use cutting machines to cut aluminum profiles. When cutting, workers place the aluminum profiles on the cutting machine, then position the aluminum profiles by hand, and use the cutting machine to cut the aluminum profiles after positioning, thereby completing the cutting of the aluminum profiles.

[0003] However, when a worker cuts an aluminum profile, he or she uses one hand to position the aluminum profile and uses the other hand to control the cutting machine to cut the aluminum profile. When the cutting machine cuts the aluminum profile, the cutting blade on the cutting machine will cause the aluminum profile to vibrate, causing the aluminum profile to be placed unstable and reducing the accuracy of the aluminum profile cutting. At the same time, one end of the aluminum profile is positioned. When the aluminum profile is about to be cut and broken, the other end of the aluminum profile cannot be positioned by positioning one 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 it easy for the cutting blade to cut the aluminum profile at an angle. When the aluminum profile is positioned by hand, the cutting blade is close to the worker's hand. There is a risk that the cutting blade touches the worker's hand, which can easily cause injury 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 technology.

[0005] To achieve the above-mentioned purpose, an aluminum profile cutting machine based on clamping fixation is provided, including a cutting seat, a positioning mechanism is arranged on the upper side of the cutting seat, 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 seat performs a preliminary positioning on the aluminum profile, in the process of the positioning mechanism driving the cutting mechanism to approach the aluminum profile, the positioning mechanism squeezes the part of the cutting seat where the aluminum profile is preliminarily positioned, in the process of the cutting mechanism cutting the aluminum profile, the positioning mechanism squeezes the aluminum profile, and as one end of the positioning mechanism continuously approaches the cutting seat, the part of the cutting seat where the aluminum profile is positioned and the squeezing force of the positioning mechanism on the aluminum profile continuously increase.

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

[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, and 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, and 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 flip member includes a flip rod, the middle position of the flip rod and the upper end of the support column are hinged, and an upward flip spring is hooked on the end of the flip rod close to the support column, the upward flip spring is arranged on the side of the support column away from the base, and the other end of the upward flip spring is hooked on the bottom of the support column, the upward flip spring pulls the end of the flip rod away from the upward flip spring to flip upward, and a grip rod is fixed on the end of the flip rod away from the upward flip spring.

[0009] As a further improvement of the present technical solution, the cutting mechanism includes a cutting head rotatably connected to an end of a flip rod away from an upward spring, a driving motor is installed on the upper side of a hinged position between the flip rod and the support column, the driving motor and the cutting head are connected via a transmission member, and 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 piece includes two elastic steel bars, which are arranged on both sides of the cutting head. The flip rod is located on the side wall between the driving motor and the cutting head and is fixed with a mounting rod. A clamping plate is fixed at both ends of the mounting rod. One end of the elastic steel bar is inserted between the clamping plate and the mounting rod, and the elastic steel bar is fixed between the clamping plate and the mounting rod using screws.

[0011] As a further improvement of the present technical solution, a sliding groove is symmetrically provided on the upper side of the pressing frame, and a clamping cavity is provided at one end of the sliding groove away from the fixed column. When the cutting machine head flips downward, one end of the elastic steel bar is inserted into the sliding groove and slides in the sliding groove along the trajectory of the sliding groove. In the process of moving 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 blocking bar, and the greater the distance that the flip rod flips downward, the greater the force with which the elastic steel bar presses the pressing frame.

[0012] As a further improvement of the technical solution, an epitaxial block is fixed near the two ends of the mounting rod, a hinge is arranged between the two elastic steel bars, the hinge is arranged on both sides of the cutting machine head, the hinge screws are fixed to the lower side of the epitaxial block, and a pressure rod is hinged at the lower end of the hinge, and one end of the pressure rod is arranged on the upper side of the baffle.

[0013] As a further improvement of the technical solution, an extension rod is fixed to the other end of the pressure rod, and 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 flips downward to press the aluminum profile blocked by the baffle bar, and as the cutting machine head continues to move downward, the pressure of the pressure rod on the aluminum profile continues to increase.

[0014] As a further improvement of the technical solution, during the downward flipping of the cutting head, one end of the elastic steel bar is first inserted into the slide groove, so that the elastic steel bar presses the pressure frame, and the pressure rod presses the aluminum profile when the cutting head cuts the aluminum profile. In the process of continuous downward movement of the cutting head, the pressure frame and the pressure rod increase the force of pressing the aluminum profile.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the clamp-fixed aluminum profile cutting machine, when placing the aluminum profile, you only need to place the aluminum profile on one side of the baffle bar, and then press the press frame on the aluminum profile. Before the cutting head cuts the aluminum profile, the elastic steel bar presses the press frame so that the aluminum profile is positioned on the baffle bar by the press frame, eliminating the trouble of workers positioning the aluminum profile by hand. At the same time, the press frame presses the aluminum profile to speed up the positioning speed of the device for the aluminum profile, thereby speeding up the workers' cutting speed of the aluminum profile.

[0016] In the aluminum profile cutting machine based on clamping fixation, when the cutting head cuts the aluminum profile, the pressure rod presses on both sides of the position where the cutting head cuts the aluminum profile, thereby improving the stability of the aluminum profile on the baffle bar, preventing the aluminum profile from being offset due to vibration when the cutting head cuts the aluminum profile, and improving the accuracy of the device in cutting the aluminum profile.

[0017] In the aluminum profile cutting machine based on clamping fixation, during the process of the cutting head cutting the aluminum profile, as the cutting head continues to move 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 continue to increase. When the aluminum profile is about to be cut and broken by the cutting head, the pressure frame cooperates with the two pressure rods to press the aluminum profile at four points, so that the ends of the aluminum profile that is about to be cut into two sections are pressed and positioned, ensuring that the aluminum profile will not shake and tilt when it is about to be cut, thereby ensuring accurate cutting of the aluminum profile. At the same time, the positioning mechanism is used to press the aluminum profile, eliminating the need for workers to position the aluminum profile, thereby improving the safety of workers cutting the aluminum profile.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1 See also Figure 1-Figure 2As shown, 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, and the worker positions the aluminum profile placed on the cutting seat 1 by hand, or clamps the aluminum profile by rotating the clamp plate to fix the position of the aluminum profile, and then drives the cutting mechanism to cut the aluminum profile through the positioning mechanism 2. However, in order to quickly position the aluminum alloy so that the aluminum alloy can be quickly cut off, the worker will use one hand to position the aluminum profile and the other hand to control the cutting. When the cutting machine cuts the aluminum profile, the cutting blade on the cutting machine will drive the aluminum profile to vibrate, causing the unstable placement of the aluminum profile and reducing the accuracy of the aluminum profile cutting. At the same time, one end of the aluminum profile is positioned. When the aluminum profile is about to be cut and broken, the other end of the aluminum profile cannot be positioned by positioning one 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 it easy for the cutting blade to cut the aluminum profile tilted. When the aluminum profile is positioned by hand, the cutting blade is close to the worker's hand, and there is a risk of the cutting blade touching the worker's hand, which can easily cause injury to the worker.

[0022] In order to speed up the positioning of the aluminum profile, ensure the accuracy of the aluminum profile cutting, and improve the safety of workers when using the device, the improvement of the present invention is that 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. In 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 where the aluminum profile is initially positioned, so that the aluminum profile is initially positioned. In the process of the cutting mechanism cutting the aluminum profile, the positioning mechanism 2 squeezes the aluminum profile, so that the aluminum profile is positioned by the cutting seat 1 and the positioning mechanism 2. The fixing of multiple points ensures that the aluminum profile will not shake when being cut. As one end of the positioning mechanism 2 continues to approach the cutting seat 1, the part of the cutting seat 1 that positions the aluminum profile and the squeezing force of the positioning mechanism 2 on the aluminum profile continue to increase, 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 the aluminum profile, the aluminum profile will not shake, ensuring the accuracy of the aluminum profile being cut. At the same time, the cutting seat 1 and the positioning mechanism 2 position the aluminum profile, eliminating the need for workers to press the aluminum profile, thereby improving the safety of workers cutting aluminum profiles.

[0023] The following is a detailed description of the structure of the cutting seat 1 and the positioning mechanism 2. Please refer to Figure 1-Figure 8As shown, the cutting seat 1 includes a base 11 and a support column 12 fixed on the upper side of the base 11 near one end, fixed columns 15 are fixedly connected to both sides of the support column 12, and a U-shaped pressing frame 13 is arranged on one side of the support column 12. The two 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 hinged position with the fixed column 15, and a baffle 14 is fixed to the end of the upper side of the base 11 away from the support column 12. The baffle 14 blocks the aluminum profile to be cut and limits the 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 baffle 14 to preliminarily position the aluminum profile.

[0024] At the same time, the positioning mechanism 2 includes a flip member 21 and a positioning member 22 arranged on the lower side of the flip member 21. The cutting mechanism is installed on the flip member 21. When the flip member 21 drives 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.

[0025] Among them, the flip member 21 includes a flip rod 211, the middle position of the flip rod 211 and the upper end of the support column 12 are hinged, and an upward flip spring 216 is hooked at one end of the flip rod 211 close to the support column 12. The upward flip spring 216 is arranged on the side of the support column 12 away from the base 11, and the other end of the upward flip spring 216 is hooked at the bottom of the support column 12. The upward flip spring 216 pulls the end of the flip rod 211 away from the upward flip spring 216 to flip upward. When the device is not in use, the flip rod 211 is flipped upward by pulling the upward flip spring 216 on the flip rod 211, so that one end of the flip rod 211 is lifted upward, so that the worker can place the aluminum profile on the base 11.

[0026] A gripping rod 212 is fixed to one end of the flipping rod 211 away from the flipping spring 216 . A worker can hold and pull the gripping rod 212 , so that the gripping rod 212 drives the flipping rod 211 to rotate around the hinged position between the flipping rod 211 and the support column 12 .

[0027] The cutting mechanism includes a cutting head 3 which is rotatably connected to the end of the flip rod 211 away from the flip spring 216. The baffle bar 14 is arranged on the side of the cutting head 3 at the lowest position away from the support column 12. When the cutting head 3 is cutting the aluminum profile blocked by the baffle bar 14, the aluminum profile will not be carried away by the friction caused by the cutting of the cutting head 3. At the same time, a driving motor 5 is installed on the upper side of the hinge position of the flip rod 211 and the support column 12. The driving motor 5 and the cutting head 3 are connected through a transmission member 4. The driving motor 5 drives the transmission member 4 to make the transmission member 4 drive the cutting head 3 to rotate.

[0028] By pressing the handle 212 downward, the flip rod 211 drives the cutting head 3 to approach the aluminum profile, so that the cutting head 3 cuts the aluminum profile. In the process of the handle 212 driving the cutting head 3 to move downward, the positioning member 22 presses the press frame 13, so that the press frame 13 preliminarily positions the aluminum profile on one side of the baffle 14. The positioning of the aluminum profile by the press frame 13 replaces the positioning effect of the worker's hand on the aluminum profile, thereby improving the safety of aluminum profile cutting.

[0029] The positioning member 22 includes two elastic steel bars 224, which are arranged on both sides of the cutting head 3. The side wall of the flip rod 211 between the driving motor 5 and the cutting head 3 is fixed with a mounting rod 213, and both ends of the mounting rod 213 are fixed with a clamping plate 217. One end of the elastic steel bar 224 is inserted between the clamping plate 217 and the mounting rod 213, and the elastic steel bar 224 is fixed between the clamping plate 217 and the mounting rod 213 by screws, so that the elastic steel bar 224 is fixed to the mounting rod 213. On the lower side, when the elastic steel bar 224 is not in contact with the pressure frame 13, the elastic steel bar 224 is tilted on the lower side of the mounting rod 213, and the tilting direction is set in the direction close to the cutting head 3. When the grip bar 212 moves downward, one end of the elastic steel bar 224 contacts the pressure frame 13, and as the grip bar 212 continues to move downward, the elastic steel bar 224 presses the pressure frame 13, so that the pressure frame 13 presses the aluminum profile blocked by the baffle bar 14, so that the aluminum profile is fixed to one side of the baffle bar 14 through the pressure of the pressure frame 13.

[0030] The spring 224 is pressed against the pressing frame 13 by the spring 224 and the spring 224 is pressed against the pressing frame 13 by the spring 224.

[0031] In order to improve the pressing effect of the elastic steel bar 224 on the pressure frame 13, a support leg 225 is fixed on one side of the elastic steel bar 224. When the elastic steel bar 224 presses the pressure frame 13, one end of the support leg 225 enters the slide groove 16, so that the elastic steel bar 224 presses the pressure frame 13 through the support leg 225, thereby forming a pressing effect of the elastic steel bar 224 on the two end positions of the pressure frame 13, thereby improving the effect of the elastic steel bar 224 pressing the pressure frame 13.

[0032] During the downward movement of the grip 212, the elastic steel bar 224 continuously increases the pressure on the pressure frame 13, so that the aluminum profile is stably fixed on one side of the baffle 14. When the cutting head 3 cuts the aluminum profile, the aluminum profile will vibrate, and the pressure frame 13 pressing the aluminum profile will position the aluminum profile. However, when the aluminum profile is about to be cut and broken, the aluminum profile is about to be cut into two parts. The position where the aluminum profile is cut will shake because the two parts of the aluminum profile are about to separate. The aluminum profile cannot be stably positioned by simply pressing the pressure frame 13 on the aluminum profile. At this time, the aluminum profile is easily driven by the cutting head 3 to shake.

[0033] Example 2 In order to ensure that the aluminum profile is accurately cut, an extension block 214 is fixed near the two ends of the mounting rod 213, and a hinge 221 is arranged between the two elastic steel bars 224. The hinge 221 is arranged on both sides of the cutting machine head 3, and the hinge 221 is screwed to the lower side of the extension block 214, and a pressure rod 222 is hinged at the lower end of the hinge 221, one end of the pressure rod 222 is arranged on the upper side of the stop bar 14, and the other end of the pressure rod 222 is fixed with a protruding rod 223, and one end of the protruding rod 223 and the mounting rod 21 A pressure rod spring 215 is connected between the lower side walls of 3, and the pressure rod spring 215 pulls one end of the extension rod 223 upward, so that one end of the pressure rod 222 is turned downward to press the aluminum profile blocked by the blocking bar 14, and as the cutting machine head 3 continues to move downward, the pressure of the pressure rod 222 on the aluminum profile is also continuously increased, so that the pressure rod 222 can stably press and position the end of the aluminum profile that is about to be cut, ensuring that the aluminum profile will not move when the aluminum profile is cut, and ensuring that the aluminum profile is accurately cut.

[0034] During the downward flipping of the cutting head 3, one end of the elastic steel bar 224 is first inserted into the slide groove 16, so that the elastic steel bar 224 presses the pressure frame 13. At this time, the pressing of the pressure frame 13 enables the aluminum profile to complete the initial positioning. 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 to be cut. During the continuous downward movement of the cutting head 3, the pressure frame 13 and the pressure rod 222 increase the pressure on the aluminum profile to ensure that the aluminum profile does not move during cutting, thereby ensuring that the aluminum profile is accurately cut.

[0035] During the process of the cutting head 3 cutting the aluminum profile, as the cutting head 3 continues to move downward, the pressure of the elastic steel bar 224 on the pressure frame 13 and the pressure of the pressure rod 222 on the aluminum profile continue to increase. When the aluminum profile is about to be cut and broken by the cutting head 3, the pressure frame 13 cooperates with the two pressure rods 222 to press the aluminum profile at four points, so that the ends of the aluminum profile that is about to be cut into two sections are pressed and positioned, ensuring that the aluminum profile will not shake and tilt when it is about to be cut, 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, thereby improving the safety of workers cutting the aluminum profile.
