Description

Technical Field

[0001] The invention relates to the technical field of profile slitting, in particular to a profile slitting machine. Background Art

[0002] Profile refers to a strip of metal that has been formed through plastic processing and has a certain cross-sectional shape and size. Pipes are also special-shaped profiles. At present, profiles have been widely used in the field of industrial manufacturing. For equipment or products that can be produced repeatedly, the length of the profile is a fixed value established according to the design drawings. In order to improve the production efficiency of equipment or products, the existing practice is to cut the long strip of profile into multiple equal-length profile sub-materials. The length of the profile can be determined by a certain multiple of the required profile sub-material length plus a reasonable cutting margin, or profiles of any length can be used directly. However, when the existing profile slitting machine cuts the profile into sections, the cutting clamping device is fixedly connected to the feeding direction of the cutting part. Therefore, the cutting clamping device hinders the feeding of the profile in the final slitting stage of the profile slitting machine, so that the existing profile slitting machine always has a long tail. If the tail is not cut twice, it will cause waste of the profile. If the tail is cut twice, it will reduce the cutting efficiency of the profile. Therefore, a profile slitting machine that can reduce the length of the tail is urgently needed. Summary of the invention

[0003] The invention aims to provide a profile slitting machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] A profile slitting machine according to a first aspect of the present invention comprises:

[0005] A frame provided with a first forward and backward moving mechanism;

[0006] A feeding device, which is slidably connected to the frame in a forward and backward manner, wherein the first forward and backward moving mechanism drives the feeding device to move forward and backward, and the feeding device is provided with a first profile clamping mechanism and a first linkage part;

[0007] A profile cutting device connected to the frame, wherein the profile cutting device is provided with a cutting portion movable leftward and rightward, and the cutting portion is located in front of the feeding device;

[0008] A feeding cutting clamping device, which is slidably connected to the frame in a forward and backward manner, and is located between the cutting part and the feeding device. The feeding cutting clamping device is provided with a second profile clamping mechanism and a second linkage part, and the second linkage part is detachably connected to the first linkage part;

[0009] The discharging cutting and clamping device is connected to the frame, the discharging cutting and clamping device is located in front of the cutting part, and the discharging cutting and clamping device is provided with a third profile clamping mechanism.

[0010] The profile slitting machine according to the embodiment of the present invention has at least the following beneficial effects: assuming that the length of each profile sub-material is x, in the process of segmented cutting of the profile created by the present invention, when the length of the profile is greater than the specified value, the first linkage part of the feeding device is not connected to the second linkage part of the feeding cutting clamping device, so that the position of the feeding cutting clamping device and the position of the profile cutting device can be relatively static, and the steps of profile slitting are as follows: the first profile clamping mechanism clamps the profile, the second profile clamping mechanism and the third profile clamping mechanism simultaneously release the profile, and then the first front-to-back moving mechanism drives the feeding device to move forward a distance of x, so that the profile passes forward over the cutting part of the profile cutting device, and then the second profile clamping mechanism and the third profile clamping mechanism simultaneously clamp the profile, and the profile cutting device starts to cut the profile. At the same time, the first profile clamping mechanism releases the profile, and the first front-to-back moving mechanism drives the feeding device to move backward. When the profile cutting device completes the cutting process, the above steps are repeated until the length of the profile is less than the specified value; when the profile When the length is less than a specified value, the first linkage part of the feeding device is connected to the second linkage part of the feeding cutting and clamping device, so that the position of the feeding cutting and clamping device and the position of the feeding device can be relatively static, so that the feeding device and the feeding cutting and clamping device can be linked to form a clamping feeding module. At this time, the profile cutting steps are as follows: the first profile clamping mechanism and the second profile clamping mechanism clamp the profile at the same time, the third profile clamping mechanism releases the profile, and then the first front-to-back moving mechanism drives the clamping feeding module to move forward x distance, causing the profile to move forward over the cutting part of the profile cutting device, and then the third profile clamping mechanism clamps the profile. At the same time, the first profile clamping mechanism and the second profile clamping mechanism simultaneously release the profile, and the first front-to-back moving mechanism drives the clamping and feeding module to move backward a distance of x. Then the first profile clamping mechanism and the second profile clamping mechanism simultaneously clamp the profile, and then the profile cutting device starts to cut the profile. When the profile cutting device completes the cutting process, the above steps are recycled until the tail length of the profile is less than x. Compared with the prior art, since the feeding cutting clamping device and the feeding device can be connected through the first linkage part and the second linkage part, the feeding cutting clamping device can become a part of the profile feeding without hindering the profile feeding, so that the profile can be segmented and cut into more profile sub-materials to avoid waste of profiles.

[0011] According to some embodiments of the present invention, the profile slitting machine also includes a first inductive sensor for detecting the length of the profile, and the first linkage part and the second linkage part together constitute a detachable linkage mechanism, and the detachable linkage mechanism is electrically connected to the first inductive sensor, so that when the length of the profile is less than a specified value, the first linkage part and the second linkage part can be automatically connected.

[0012] According to some embodiments of the present invention, in order to eliminate the influence of the feeding device on the first induction sensor, the first induction sensor is arranged in the feeding device, and the first induction sensor is located behind the first profile clamping mechanism to ensure that when the first linkage part is automatically connected with the second linkage part, the first profile clamping mechanism can clamp the profile.

[0013] According to some embodiments of the invention, the first linkage part is a hook, and the second linkage part is a movable ear, so that the ear can be buckled with the hook. When the length of the profile is less than a specified value, the first forward and backward moving mechanism drives the feeding device forward to abut against the feeding cutting clamping device, so that the hook is located on the moving path of the ear, and then the ear moves to buckle with the hook.

[0014] According to some embodiments created by the present invention, guide rails arranged along the front-to-back direction are provided on the left and right sides of the frame; the feeding device is also provided with a first mounting plate, and the feeding cutting and clamping device is also provided with a second mounting plate, and the first mounting plate and the second mounting plate are both connected with sliders for sliding connection with the guide rails, so that the first mounting plate and the second mounting plate can be slidably connected to the frame forward and backward.

[0015] According to some embodiments of the present invention, a height adjustment mechanism is connected between the first mounting plate and the second mounting plate and the corresponding slider to perform installation calibration on the height of the first mounting plate and the height of the second mounting plate.

[0016] According to some embodiments of the present invention, the first profile clamping mechanism is connected to the upper surface of the first mounting plate, and the first linkage part is connected to the lower bottom surface of the first mounting plate; the second profile clamping mechanism is connected to the upper surface of the second mounting plate, and the second linkage part is connected to the lower bottom surface of the second mounting plate. The first linkage part and the second linkage part are arranged to avoid interference with the movement of the profile.

[0017] According to some embodiments of the invention, the discharging, cutting and clamping device is further provided with a discharging support plate, the upper surface of which is connected to the third profile clamping mechanism, the discharging support plate is connected to the frame in a forward and backward sliding manner, and the discharging support plate is connected to a second forward and backward moving mechanism for driving the discharging support plate to move forward and backward. Through the above arrangement, after the cutting part completes the cutting of the profile, the second forward and backward moving mechanism drives the discharging support plate to move forward, and at the same time, the feeding device or the clamping feeding module drives the profile to move backward, so that the cut of the profile can be separated from the cutting part, avoiding scratches on the cut of the profile due to friction between the cutting part and the cut of the profile when resetting.

[0018] According to some embodiments created by the present invention, in order to provide a basis for positioning the profile, the feeding device, the feeding cutting and clamping device and the discharging cutting and clamping device are all provided with a positioning vertical support plate, and all the positioning vertical support plates have the same positioning reference plane, which is orthogonal to the cutting direction of the cutting part.

[0019] According to some embodiments of the present invention, in order to facilitate the positioning of the profile, the feeding device and the feeding, cutting and clamping device are both provided with a profile positioning mechanism for pushing the profile toward the positioning vertical support plate.

[0032] like Figure 1As shown, the profile slitting machine according to the first embodiment of the invention includes a frame 100, a supporting roller 200, a feeding device 300, a feed cutting clamping device 400, a profile cutting device 500 and a discharge cutting clamping device 600, the profile cutting device 500 is provided with a cutting portion 530 which can be moved left and right, the supporting roller 200, the feeding device 300, the feed cutting clamping device 400, the cutting portion 530 and the discharge cutting clamping device 600 are all connected to the frame 100 in sequence from back to front; the supporting roller 200 is used to support the profile, the profile cutting device 500 is used to cut the profile in sections, the discharge cutting clamping device 600 and the feed cutting clamping device 400 are both close to the profile cutting device 500, the discharge cutting clamping device 600 and the feed cutting clamping device 400 are respectively used to clamp the two sides of the profile cut to prevent the profile from shifting during slitting.

[0033] Specifically, Figure 2 and Figure 3As shown, the left and right sides of the frame 100 are provided with guide rails 110 arranged along the front-to-back direction, and the frame 100 is installed with a first front-to-back moving mechanism 120 between the two guide rails 110. The first front-to-back moving mechanism 120 can be optionally a screw-nut mechanism, and the screw-nut mechanism is provided with a moving block that moves along the front-to-back direction. The feeding device 300 includes a first mounting plate 310, a first profile clamping mechanism 320 and a first linkage part 330. The first mounting plate 310 is connected to a slider for slidingly connecting with the guide rail 110, so that the first mounting plate 310 can be slidably connected to the frame 100 forward and backward. The first mounting plate 310 is connected to the moving block of the screw nut mechanism, so that the screw nut mechanism can drive the first mounting plate 310 to move forward and backward. The feeding device 300 and the first forward and backward moving mechanism 120 are used together to transport the profile forward to the profile cutting device 500; the upper surface of the first mounting plate 310 is connected to the first profile clamping mechanism 320, and the first profile clamping mechanism 320 can be optionally a downward clamping cylinder clamping mechanism, and the lower bottom surface of the first mounting plate 310 is connected to the first linkage part 330. The feed cutting and clamping device 400 includes a second mounting plate 410, a second profile clamping mechanism 420 and a second linkage part 430. The second mounting plate 410 is connected to a slider for slidingly connecting with the guide rail 110, so that the second mounting plate 410 can be slidably connected to the frame 100 forward and backward. The upper surface of the second mounting plate 410 is connected to the second profile clamping mechanism 420, and the second profile clamping mechanism 420 can be optionally a downward clamping cylinder clamping mechanism. The lower bottom surface of the second mounting plate 410 is connected to the second linkage part 430. The first linkage part 330 is detachably connected to the first linkage part 330 and together constitute a detachable linkage mechanism. The first linkage part 330 may be a hook, and correspondingly, the second linkage part 430 may be a movable pull ear. When the two need to be connected, the first forward and backward moving mechanism 120 drives the first mounting plate 310 to abut against the second mounting plate 410 forward, so that the hook is located on the moving path of the pull ear, and then the pull ear is moved manually or automatically to be buckled with the hook; when the first linkage part 330 is connected to the second linkage part 430, the second mounting plate 410 can move with the first mounting plate 310. Figure 4 As shown, the discharge cutting and clamping device 600 includes a discharge supporting plate 610 and a third profile clamping mechanism 620. The discharge supporting plate 610 is connected to the frame 100. The upper surface of the discharge supporting plate 610 is connected to the third profile clamping mechanism 620. The third profile clamping mechanism 620 can be a downward clamping cylinder clamping mechanism. All the segmented profile sub-materials are stored on the discharge supporting plate 610. Figure 6 As shown, the profile cutting device 500 includes a left-right moving mechanism 510, a third mounting plate 520, a left-right adjusting mechanism 540 and a cutting part 530 driven by a motor 531. The cutting part 530 can be selected as a saw blade or a grinding wheel, and the type of the cutting part 530 depends on the material of the profile. The cutting part 530 is installed on the third mounting plate 520, and the third mounting plate 520 is connected to the frame 100 for sliding left and right. The left-right moving mechanism 510 is installed on the frame 100. The left-right moving mechanism 510 can be selected as a cylinder telescopic mechanism, and the telescopic rod of the cylinder telescopic mechanism is fixedly connected to the third mounting plate 520, so that the cutting part 530 can be moved left and right through the cylinder telescopic mechanism to achieve segmented cutting of the profile; the left The right adjustment mechanism 540 is connected to a second inductive sensor 541, which can be a proximity switch. The second inductive sensor 541 is located on the moving path of the third mounting plate 520. The second inductive sensor 541 is used to control the movement of the left-right moving mechanism 510 and the motor 531. The left-right adjustment mechanism 540 manually adjusts the left-right position of the second inductive sensor 541. When the third mounting plate 520 moves to the left to trigger the second inductive sensor 541, the left-right moving mechanism 510 will drive the third mounting plate 520 to reset to the right, and the motor 531 stops rotating to limit the cutting width of the cutting part 530, thereby realizing fast segmented cutting of profiles of different widths. It should be noted that the invention does not limit the specific structure of the left-right adjustment mechanism 540. As long as the left-right adjustment mechanism 540 is used to adjust the left-right position of the second inductive sensor 541, no matter what structure the left-right adjustment mechanism 540 is, it belongs to the protection scope of the invention.

[0034] It can be understood that the first front-to-back moving mechanism 120 and the left-to-right moving mechanism 510 can also be linear moving mechanisms such as electric push rods and linear motors, and are not limited to the above embodiments. However, since the present invention requires precise control of the stroke of the feeding device 300, the first front-to-back moving mechanism 120 is preferably a screw-nut mechanism driven by a servo motor; in addition, the first linkage part 330 and the second linkage part 430 can also be detachable linkage mechanisms of other different structures, for example, the first linkage part 330 is a magnetic conductor, and the second linkage part 430 is an electromagnet.

[0035] In some embodiments of the present invention, since the first mounting plate 310 and the second mounting plate 410 are both movable, their heights may be inconsistent with the height of the discharge support plate 610 due to the gap difference, resulting in the profile being unable to be laid flat. In order to solve the above technical problems, the first mounting plate 310 and the second mounting plate 410 are both connected to the corresponding sliders with a height adjustment mechanism 303, that is, each slider is connected to a height adjustment mechanism 303, and the height adjustment mechanism 303 can be manually adjusted to calibrate the height of the first mounting plate 310 and the height of the second mounting plate 410, so that the first mounting plate 310, the second mounting plate 410 and the discharge support plate 610 can be on the same horizontal plane. It should be noted that the present invention does not limit the specific structure of the height adjustment mechanism 303. As long as the height adjustment mechanism 303 is used to adjust the height of the two mounting plates, no matter what structure the height adjustment mechanism 303 is, it belongs to the protection scope of the present invention.

[0036] Using the above structure, assuming that the length of each profile sub-material is x, in the process of segmented cutting of the profile created by the present invention, when the length of the profile is greater than the specified value, that is, when there is a large amount of cutting margin in the profile, the first linkage part 330 of the feeding device 300 is not connected to the second linkage part 430 of the feeding cutting clamping device 400, so that the position of the feeding cutting clamping device 400 and the position of the profile cutting device 500 can be relatively stationary. At this time, the steps of profile cutting are as follows: 1. The first profile clamping mechanism 320 clamps the profile, and the second profile clamping mechanism 420 and the third profile clamping mechanism 620 are simultaneously 1. The first front-to-back moving mechanism 120 drives the feeding device 300 to move forward a distance x, so that the profile moves forward over the cutting portion 530 of the profile cutting device 500; 2. The second profile clamping mechanism 420 and the third profile clamping mechanism 620 clamp the profile at the same time, and the profile cutting device 500 starts to cut the profile; 3. The first profile clamping mechanism 320 releases the profile, and the first front-to-back moving mechanism 120 drives the feeding device 300 to move backward; 4. When the profile cutting device 500 completes the cutting process, steps 1 to 4 are repeated until the length of the profile is less than the specified value. In the above steps, the invention is always in the long material cutting stage to achieve rapid segmented cutting of the profile.

[0037] When the length of the profile is less than the specified value, that is, when there is a small cutting margin in the profile, the first linkage part 330 of the feeding device 300 and the second linkage part 430 of the feeding cutting clamping device 400 can be connected manually or automatically, so that the position of the feeding cutting clamping device 400 and the position of the feeding device 300 can be relatively static, so that the feeding device 300 and the feeding cutting clamping device 400 can be linked to form a clamping feeding module. At this time, the steps of profile cutting are as follows: 1. The first profile clamping mechanism 320 and the second profile clamping mechanism 420 clamp the profile at the same time, and the third profile clamping mechanism 620 releases the profile; 2. The first forward and backward movement Mechanism 120 drives the clamping and feeding module to move forward a distance x, so that the profile moves forward over the cutting portion 530 of the profile cutting device 500, and the third profile clamping mechanism 620 clamps the profile; 3. The first profile clamping mechanism 320 and the second profile clamping mechanism 420 release the profile at the same time, and the first front-to-back moving mechanism 120 drives the clamping and feeding module to move backward a distance x; 4. The first profile clamping mechanism 320 and the second profile clamping mechanism 420 clamp the profile at the same time, and the profile cutting device 500 starts to cut the profile; 5. When the profile cutting device 500 completes the cutting process, steps 1 to 4 are recycled until the tail length of the profile is less than x.

[0038] In other embodiments, when the length of the profile is less than a specified value, the slitting of the profile can also be carried out in the following steps: 1. The first profile clamping mechanism 320 and the second profile clamping mechanism 420 clamp the profile at the same time, and the third profile clamping mechanism 620 releases the profile; 2. The first front-to-back moving mechanism 120 drives the clamping and feeding module to move forward a distance a, so that the profile passes forward over the cutting portion 530 of the profile cutting device 500, and the third profile clamping mechanism 620 clamps the profile; 3. The first profile clamping mechanism 320 and the second profile clamping mechanism 420 release the profile at the same time, and the first front-to-back moving mechanism 120 drives the clamping and feeding module to move forward a distance a, so that the profile passes forward over the cutting portion 530 of the profile cutting device 500, and the third profile clamping mechanism 620 clamps the profile; The clamping and feeding module moves backward a distance of x; 4. The first profile clamping mechanism 320 and the second profile clamping mechanism 420 clamp the profile at the same time, and the third profile clamping mechanism 620 releases the profile; 5. The first front-to-back moving mechanism 120 drives the clamping and feeding module to move forward a distance of b, and a+b=x; 6. The first profile clamping mechanism 320, the second profile clamping mechanism 420 and the third profile clamping mechanism 620 clamp the profile at the same time, and the profile cutting device 500 starts to cut the profile; 7. When the profile cutting device 500 completes the cutting process, steps 1 to 6 are circulated until the length of the tail of the profile is less than x. Although the above two steps adopt different methods, the technical effects achieved by the two steps are similar, and users can choose one to implement according to actual needs.

[0039] In the above two steps, the invention is always in the tail cutting stage. In this tail cutting stage, the feed cutting clamping device 400 is linked with the feeding device 300 to form a clamping feeding module. Therefore, at this time, the feed cutting clamping device 400 can become a part of the feeding of the profile without hindering the feeding of the profile, so that the profile can be segmented and cut into more profile sub-materials to avoid waste of the profile. It should be noted that when the invention is in the tail cutting stage, with the continuous segmentation of the profile, the first profile clamping mechanism 320 of the feeding clamping module will have an empty clamping stage. This is because the length of the profile is not enough to be clamped by the first profile clamping mechanism 320. At this time, the feeding clamping module mainly relies on the second profile clamping mechanism 420 to clamp the profile.

[0040] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, after the left-right moving mechanism 510 drives the cutting part 530 to complete the cutting of the profile, in the prior art, the left-right moving mechanism 510 will immediately drive the cutting part 530 to reset. Since the cutting part 530 may rub against the cut of the profile during the resetting process, the cutting part 530 is likely to leave scratches on the cut of the profile, thereby affecting the quality of the profile sub-material. To this end, a sliding assembly 630 is connected between the discharging pallet 610 and the frame 100, and the sliding assembly 630 includes a fixed block 631 and a sliding block 632 that can slide forward and backward along the fixed block 631. The fixed block 631 is fixedly connected to the frame 100, and the sliding block 632 is fixedly connected to the discharging pallet 610, so that the discharging pallet 610 can be slidably connected to the frame 100 forward and backward. The discharging pallet 610 is connected to a second forward and backward moving mechanism 640 for driving the discharging pallet 610 to move forward and backward. The second forward and backward moving mechanism 640 can be optionally a cylinder, whose cylinder body is installed on the bottom surface of the discharging pallet 610, and whose telescopic rod is installed on the fixed block 631. After the cutting part 530 completes cutting of the profile, the second front-to-back moving mechanism 640 drives the discharge pallet 610 to move forward, and at the same time, the feeding device 300 or the clamping feeding module drives the profile to move backward, so that the cut of the profile can be separated from the cutting part 530; thereafter, the left-right moving mechanism 510 drives the cutting part 530 to reset, and when the cutting part 530 completes the reset, the discharge pallet 610 and the feeding device 300 or the clamping feeding module are reset successively.

[0041] In some embodiments of the present invention, since the activation of the detachable linkage mechanism is based on the length of the profile, in order to detect the length of the profile, the profile slitting machine also includes a first inductive sensor (not shown in the drawings), which can be a photoelectric sensor or a proximity switch, which is connected to the first mounting plate 310 and is located behind the first profile clamping mechanism 320. Once the first inductive sensor fails to detect the profile, the first inductive sensor immediately feeds back the detection electrical signal to the controller of the profile slitting machine, and then the controller issues an instruction to prompt the feeding device 300 to be connected with the feeding cutting clamping device 400 through the detachable linkage mechanism, so as to realize the automatic switching of the present invention from the long material slitting stage to the tail material slitting stage. It can be understood that even if the first inductive sensor is not provided, the present invention can still switch the present invention from the long material slitting stage to the tail material slitting stage manually, but this is obviously not conducive to the realization of automated production.

[0042] like Figures 2 to 4 As shown, the feeding device 300, the feeding cutting clamping device 400 and the discharging cutting clamping device 600 are all provided with a positioning vertical support plate 301, all the positioning vertical support plates 301 are located on the right side of the corresponding device, and all the positioning vertical support plates 301 have the same positioning reference surface, which is orthogonal to the cutting direction of the cutting part 530. Before cutting the profile, the profile needs to be positioned, and when the profile abuts against all the positioning vertical support plates 301, it means that the profile has been positioned.

[0043] Furthermore, in order to facilitate the positioning of the profile, the feeding device 300, the feeding cutting clamping device 400 and the discharging cutting clamping device 600 are all provided with a profile positioning mechanism 302 for pushing the profile toward the positioning vertical leaning plate 301. The profile positioning mechanism 302 includes a hand wheel, a screw rod and a slider driven by the screw rod. The hand wheel is synchronously connected with the screw rod, and the slider can be moved left and right by rotating the hand wheel, thereby pushing the profile toward the positioning vertical leaning plate 301 to replace the manual pushing method. It should be noted that the discharging cutting clamping device 600 may not be provided with the profile positioning mechanism 302, and is not limited to the above embodiment.

[0044] like Figure 1 and Figure 2As shown, in order to better clamp and feed the profile, the upper surface of the first mounting plate 310 is connected with a fourth profile clamping mechanism 340, and the fourth profile clamping mechanism 340 can be a downward clamping cylinder clamping mechanism, and the fourth profile clamping mechanism 340 is located behind the first profile clamping mechanism 320, and the fourth profile clamping mechanism 340 moves synchronously with the first profile clamping mechanism 320 to clamp and feed the profile together. Since the cutting efficiency of the present invention is reduced when it is in the tail material cutting stage, the first induction sensor is preferably located between the first profile clamping mechanism 320 and the fourth profile clamping mechanism 340 in order to enable the present invention to switch to the tail material cutting stage prematurely.

[0045] like Figure 1 As shown, in order to prevent chips from flying and avoid the cutting part 530 from injuring people, the frame 100 can be provided with a protective cover 130 at the corresponding positions of the profile cutting device 500 and the discharge cutting clamping device 600 to improve the safety factor of the invention.
