Description

Technical Field

[0001] The utility model relates to the technical field of metal cutting, in particular to a fixed-distance cutting structure for metal processing. Background Art

[0002] Profiles refer to solid straight bars formed by plastic processing of metals, having a certain cross-sectional shape and size. There are a wide variety of profile varieties and specifications, and they are widely used, occupying a very important position in rolling production. When profiles are processed and used, they need to be cut into specified lengths according to actual needs, which is convenient for splicing between profiles and can also minimize the waste of profiles.

[0003] In the patent document with the published publication number CN213969239U, a cutting device for metal product processing with an equidistant measurement and cutting structure is provided. Through the structural design between the sliding scales in this utility model, workers can quickly and clearly know the required length for each cutting. At the same time, the structural design between the infrared lamp and the infrared receiver enables workers to more accurately know the cutting position.

[0004] When the above-mentioned utility model is in use, workers need to first observe the size of the metal product to be processed and adjust the length of the telescopic rod so that the distance between the two movable fixing blocks fits the size of the metal product to be processed, thereby realizing the function of fixed-distance cutting. The above fixed-distance method is relatively inconvenient in actual use. Firstly, it is necessary to manually and accurately adjust the distance between the two movable fixing blocks, and the operation difficulty is relatively large. Secondly, when a profile needs to be cut into different lengths, it is necessary to frequently adjust the distance between the movable fixing blocks, resulting in poor continuity of the cutting work and a large amount of time-consuming in the adjustment work. Therefore, in view of the above problems, a fixed-distance cutting structure for metal processing is proposed. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a fixed-distance cutting structure for metal processing. The metal cutting structure drives the profile fixture to move through a lead screw transmission mechanism, and sends the profile fixed on the profile fixture to the profile cutting machine for cutting. During this process, the movement of the sliding table will synchronously drive the movement of the magnetic ring, that is, the position of each sliding table corresponds to the spatial position of a magnetic ring, and the spatial position of the magnetic ring can be detected in real time by a magnetostrictive displacement sensor. Therefore, the movement of the profile can be accurately detected by the magnetostrictive displacement sensor. Through the data feedback of the magnetostrictive displacement sensor, the length of the profile to be cut currently can be known, and then the cutting length can be freely selected, solving the technical problem that it is difficult to efficiently and freely select and change the cutting length at any time when performing fixed-distance cutting on metal profiles in the prior art.

[0006] The technical solution adopted by the embodiments of the present application to solve its technical problems is as follows:

[0007] A fixed-distance cutting structure for metal processing, including a workbench, which is provided with a fixture chute in the middle, and a profile cutting machine is installed at the rear side of the upper end surface thereof. A profile fixture is slidably arranged in the fixture chute for clamping the profile to be cut. A screw drive mechanism is arranged on the lower end surface of the workbench, and a magnetostrictive displacement sensor is arranged below the screw drive mechanism. Among them, the screw drive mechanism includes a drive motor, a screw rod, and a sliding table. The lower end of the profile fixture is fixedly connected to the sliding table, and the magnetic ring on the measuring rod of the magnetostrictive displacement sensor is fixedly arranged on the lower end surface of the sliding table through a magnetic ring fixing piece.

[0008] Through the above structural form, the drive motor drives the screw rod to rotate and then drives the sliding table to slide, so that the profile fixture moves synchronously, and the fixedly clamped profile is sent to the profile cutting machine for cutting. During this process, the movement of the sliding table will synchronously drive the magnetic ring on the measuring rod of the magnetostrictive displacement sensor to move, and the spatial position of the magnetic ring can be detected by the magnetostrictive displacement sensor in real time. Therefore, the movement situation of the profile can be accurately detected by the magnetostrictive displacement sensor. Through the data feedback of the magnetostrictive displacement sensor, the length of the profile to be cut currently can be known, and thus the cutting length can be freely selected during cutting.

[0009] In a possible implementation manner, the drive motor is arranged at the end of the workbench through an end mounting plate. The output shaft of the drive motor is in transmission connection with the screw rod. The screw rod passes through the middle of the sliding table and is in threaded connection with it. And one end of the screw rod far from the drive motor is rotatably connected with a lapping sheet body, and the top of the lapping sheet body is fixedly connected to the workbench.

[0010] Through the above structural form, the overall fixed installation of the screw drive mechanism can be realized, so that each component included in it can play its own function.

[0011] In a possible implementation manner, guide rods fixedly installed on the lower end surface of the workbench are arranged on both sides of the screw rod. Guide cylinders are slidably sleeved on the guide rods, and the side surface of the guide cylinder is fixedly connected to the side surface of the sliding table.

[0012] Through the above structural form, the sliding of the sliding table can be supported and guided in the way that the guide cylinder slides along the guide rod, so that the sliding table can slide smoothly between the guide rods.

[0013] In a possible implementation manner, the electronic bin part of the magnetostrictive displacement sensor is fixedly suspended under the workbench through a U-shaped mounting plate. The rod end of the measuring rod of the magnetostrictive displacement sensor is fixedly connected with a U-shaped rod, and both ends of the U-shaped rod are fixedly connected to the lower end surface of the workbench.

[0014] Through the above structural form, the fixed installation of the overall structure of the magnetostrictive displacement sensor can be realized, enabling it to be fixedly arranged under the workbench to play the role of displacement detection.

[0015] In a possible implementation manner, the magnetic ring fixing member includes a ring fixing plate and a ring pressing plate. The ring fixing plate is fixedly arranged on the lower end face of the sliding table. The ring pressing plate is fixedly connected to the ring fixing plate by screws, and fixing grooves for clamping the magnetic ring of the magnetostrictive displacement sensor are formed on the opposite end faces of the ring fixing plate and the ring pressing plate.

[0016] Through the above structural form, the magnetic ring on the magnetostrictive displacement sensor can be fixedly connected to the sliding table by the clamping action of the ring pressing plate and the ring fixing plate, so that the movement of the sliding table can synchronously cause the data change of the magnetostrictive displacement sensor.

[0017] In a possible implementation manner, the profile clamp includes a slider slidably arranged in the clamp chute. An L-shaped plate is fixedly connected to the upper end face of the slider. A portal frame is arranged on the upper end face of the L-shaped plate. A movable pressing plate is slidably arranged in the portal frame. A threaded rod with a handwheel at the top is threadedly connected to the portal frame, and the bottom end of the threaded rod is rotatably connected to the movable pressing plate.

[0018] Through the above structural form, when the handwheel is rotated, the threaded rod threadedly connected to the portal frame will move up and down, so that the movable pressing plate connected to the bottom of the threaded rod will move up and down synchronously, thereby changing the distance between the movable pressing plate and the L-shaped plate to meet the clamping requirements of profiles of different sizes.

[0019] In a possible implementation manner, a convex groove is formed on the upper end face of the profile cutting machine base, and a positioning sliding plate is slidably arranged in the convex groove. The plane where the front end face of the positioning sliding plate is located coincides with the plane where the cutting wheel part of the profile cutting machine is located.

[0020] Through the above structural form, the positioning and calibration functions can be achieved through the positioning sliding plate. Since there may still be a gap between the end of the profile and the profile cutting machine after the profile is installed, the first part of the distance traveled by the sliding table when pushing the profile towards the profile cutting machine cannot cause a change in the cutting distance length. At this time, the data change of the magnetostrictive displacement sensor does not represent the change in the cutting length. However, after the profile is moved to fit the end with the positioning sliding plate before cutting, the subsequent data change of the magnetostrictive displacement sensor represents the change in the cutting length, which is more intuitive.

[0021] In a possible implementation manner, a C-shaped guide plate is detachably arranged at a position on the upper end face of the workbench close to the clamp chute. A guide opening is formed at one end of the C-shaped guide plate close to the clamp chute.

[0022] With the above structural form, the C-shaped guide plate can play a role in restraining the front end of the profile, preventing the profile from shifting during movement, and the C-shaped guide plate with corresponding dimensions can be replaced according to different profiles to meet the restraining effect.

[0023] In summary, the utility model includes the following beneficial technical effects:

[0024] The driving motor drives the screw rod to rotate, and then drives the sliding table to slide, so that the profile fixture moves synchronously, and the fixedly clamped profile is sent to the profile cutting machine for cutting. During this process, the movement of the sliding table will synchronously drive the magnetic ring on the measuring rod of the magnetostrictive displacement sensor to move, and the spatial position of the magnetic ring can be detected in real time by the magnetostrictive displacement sensor. Therefore, the movement of the profile can be accurately detected by the magnetostrictive displacement sensor. Through the data feedback of the magnetostrictive displacement sensor, the length of the profile to be cut currently can be known, and then the cutting length can be freely selected during cutting.

[0034] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0035] As Figure 1 - Figure 3 As shown, a fixed-distance cutting structure for metal processing provided in this embodiment includes a workbench 1, in which a fixture chute 11 is opened in the middle, and a profile cutting machine 3 is installed at the rear side of the upper end surface thereof, a profile fixture 2, which is slidably arranged in the fixture chute 11 for clamping the profile to be cut, a lead screw drive mechanism 4, which is arranged on the lower end surface of the workbench 1, and a magnetostrictive displacement sensor 5, which is arranged below the lead screw drive mechanism 4; wherein, the lead screw drive mechanism 4 includes a driving motor 41, a lead screw 42 and a slide table 43, the lower end of the profile fixture 2 is fixedly connected to the slide table 43, and the magnet ring on the measuring rod of the magnetostrictive displacement sensor 5 is fixedly arranged on the lower end surface of the slide table 43 through a magnet ring fixing piece 6.

[0036] Through the above structural form, the driving motor 41 drives the lead screw 42 to rotate and then drives the slide table 43 to slide, so that the profile fixture 2 moves synchronously, and the fixedly clamped profile is sent to the profile cutting machine 3 for cutting. During this process, the movement of the slide table 43 will synchronously drive the magnet ring on the measuring rod of the magnetostrictive displacement sensor 5 to move, and the spatial position of the magnet ring can be detected in real time by the magnetostrictive displacement sensor 5. Therefore, the movement situation of the profile can be accurately detected by the magnetostrictive displacement sensor 5. By the data feedback of the magnetostrictive displacement sensor 5, the length of the profile to be cut currently can be known, and thus the cutting length can be freely selected during cutting.

[0037] As Figure 4 - Figure 5As shown, the drive motor 41 is arranged at the end of the workbench 1 through the end mounting plate 411. The output shaft of the drive motor 41 is in transmission connection with the lead screw 42. The lead screw 42 passes through the middle of the sliding table 43 and is threadedly connected thereto. And one end of the lead screw 42 away from the drive motor 41 is rotatably connected with a lapping sheet body, and the top of the lapping sheet body is fixedly connected with the workbench 1. Through the above structural form, the overall fixed installation of the lead screw transmission mechanism 4 can be realized, so that each component included therein can play its own function.

[0038] In addition, guide rods 45 fixedly installed on the lower end surface of the workbench 1 are arranged on both sides of the lead screw 42. A guide cylinder 44 is slidably sleeved on the guide rods 45. The side surface of the guide cylinder 44 is fixedly connected with the side surface of the sliding table 43. Through the above structural form, the sliding of the sliding table 43 can be supported and guided in the way that the guide cylinder 44 slides along the guide rods 45, so that the sliding table 43 can slide smoothly between the guide rods 45.

[0039] As Figure 4 、 Figure 7 shown, the electronic bin part of the magnetostrictive displacement sensor 5 is fixedly suspended below the workbench 1 through a U-shaped mounting plate 51. The rod end of the measuring rod of the magnetostrictive displacement sensor 5 is fixedly connected with a U-shaped rod 52, and both ends of the U-shaped rod 52 are fixedly connected to the lower end surface of the workbench 1. Through the above structural form, the overall structure of the magnetostrictive displacement sensor 5 can be fixedly installed, so that it can be fixedly arranged below the workbench 1 to play a role in displacement detection.

[0040] As Figure 7 shown, the magnetic ring fixing member 6 includes a ring fixing piece 61 and a ring pressing piece 62. Among them, the ring fixing piece 61 is fixedly arranged on the lower end surface of the sliding table 43. The ring pressing piece 62 is fixedly connected with the ring fixing piece 61 by screws. And fixing grooves 63 for clamping the magnetic ring of the magnetostrictive displacement sensor 5 are formed on the opposite end surfaces of the ring fixing piece 61 and the ring pressing piece 62. Through the above structural form, the magnetic ring on the magnetostrictive displacement sensor 5 can be fixedly connected with the sliding table 43 by the clamping action of the ring pressing piece 62 and the ring fixing piece 61, so that the movement of the sliding table 43 can synchronously cause the data change of the magnetostrictive displacement sensor 5.

[0041] As Figure 6As shown in the figure, the profile clamp 2 includes a slider 21 slidably arranged in the clamp chute 11. The upper end surface of the slider 21 is fixedly connected with an L-shaped plate 22. The upper end surface of the L-shaped plate 22 is provided with a portal frame 23. An active pressure plate 24 is slidably arranged in the portal frame 23. A threaded rod 25 with a handwheel 26 at the top is threadedly connected to the portal frame 23. The bottom end of the threaded rod 25 is rotatably connected to the active pressure plate 24. Through the above structural form, when the handwheel 26 is rotated, the threaded rod 25 threadedly connected to the portal frame 23 will move up and down, so that the active pressure plate 24 connected to the bottom of the threaded rod 25 will move up and down synchronously, thereby changing the distance between the active pressure plate 24 and the L-shaped plate 22 to meet the clamping requirements of profiles of different sizes.

[0042] As Figure 5 shown in the figure, a convex groove 31 is opened on the base of the profile cutting machine 3. A positioning slide plate 32 is slidably arranged in the convex groove 31. The plane where the front end surface of the positioning slide plate 32 is located coincides with the plane where the cutting wheel part of the profile cutting machine 3 is located. Through the above structural form, the positioning and calibration functions can be achieved through the positioning slide plate 32. Since there may still be a gap between the end of the profile after installation and the profile cutting machine 3, the first part of the distance traveled when the sliding table 43 moves to push the profile towards the profile cutting machine 3 cannot cause a change in the cutting distance length. At this time, the data change of the magnetostrictive displacement sensor 5 does not represent the change in the cutting length. However, after the profile is moved to fit the end with the positioning slide plate 32 before cutting, the subsequent data change of the magnetostrictive displacement sensor 5 represents the change in the cutting length, which is more intuitive.

[0043] As Figure 4 - Figure 5 shown in the figure, a C-shaped guide plate 7 is detachably arranged on the upper end surface of the workbench 1 near the clamp chute 11. A guide port 71 is opened at one end of the C-shaped guide plate 7 close to the clamp chute 11. Through the above structural form, the C-shaped guide plate 7 can play a role in restraining the front end of the profile, avoiding the profile from shifting during the movement, and the C-shaped guide plate 7 with a corresponding size can be replaced according to different profiles to meet the restraining effect.

[0044] The working principle and process of the present utility model:

[0045] The driving motor 41 drives the lead screw 42 to rotate, thereby driving the sliding table 43 to slide, so that the profile clamp 2 moves synchronously, and the fixedly clamped profile is sent to the profile cutting machine 3 for cutting. During this process, the movement of the sliding table 43 will synchronously drive the magnetic ring on the measuring rod of the magnetostrictive displacement sensor 5 to move, and the spatial position of the magnetic ring can be detected by the magnetostrictive displacement sensor 5 in real time. Therefore, the movement of the profile can be accurately detected by the magnetostrictive displacement sensor 5. Through the data feedback of the magnetostrictive displacement sensor 5, the length of the profile to be cut currently can be known, and thus the cutting length can be freely selected during cutting.

[0046] In addition, before the formal cutting starts, the profile needs to be moved to the end and fitted with the positioning slide plate 32. At this time, if the profile cutting machine 3 cuts, the cutting amount is zero. However, any distance of the subsequent movement of the profile is equivalent to the cutting length, and the specific value of the data change of the subsequent magnetostrictive displacement sensor 5 can also represent the change of the cutting length, which is more intuitive.

[0047] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
