Technical Field

[0001] The invention relates to the technical field of metal processing equipment, in particular to a metal shaft shearing machine. Background Art

[0002] In the metal processing industry, the production process of metal shaft parts often requires cutting long shaft materials into specific lengths, and then polishing the cut parts to remove burrs on the rear end surface of the long shaft materials after cutting.

[0003] In existing metal processing equipment, long shaft materials are usually cut and sheared sequentially, and then the ends of the long shaft materials are polished by polishing equipment after shearing. This has low work efficiency and is difficult to perform synchronous shearing of long shaft materials of multiple sizes. Moreover, when cutting to a specified length, the long shaft materials need to be re-positioned and measured, which increases the workload.

[0004] Therefore, it is necessary to provide a kind of metal shaft shearing machine to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a metal shaft shearing machine to solve the problems existing in the above-mentioned background technology. The technical solution of the present invention is aimed at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a metal shaft shearing machine, comprising a base plate, the four bottom corners of the base plate being connected to supporting feet, a first groove being provided on one side of the top of the base plate at equal intervals from front to back, positioning seats for positioning shaft workpieces being installed at both ends of the interior of the first groove, a second groove being provided in the center direction between two adjacent groups of the first grooves, adjustment mechanisms for adjusting the center position of the shaft workpiece being installed at both ends of the interior of the second groove, a support seat being installed on the other side of the top of the base plate, and a shearing mechanism being installed on the inner side of the support seat.

[0007] Preferably, a threaded rod is rotatably connected to the interior of the first groove, and two groups of threaded plates with gaps are threadedly connected to the outer wall of the threaded rod, and the top of the threaded plate is connected to the bottom of the positioning seat.

[0008] Preferably, the front and rear ends of the top of the positioning seat are provided with slots, a hydraulic plate is installed inside the slot, and the top of the telescopic end of the hydraulic plate is connected to a pressing seat.

[0009] Preferably, the adjustment mechanism includes a bidirectional screw rotatably installed inside the second groove, threaded seats are installed at both ends of the outer wall of the bidirectional screw, the top of the threaded seat is connected to an arc seat, the top two ends of the arc seat are connected to circular plates, a rotating plate is rotatably connected between the two groups of circular plates, the outer wall of the rotating plate is connected to a connecting block, and the other end of the connecting block is connected to a splint.

[0010] Preferably, a connecting rod is provided between the two groups of rotating plates for connection, and a driving device for driving the rotating plates to rotate is installed on one side of the circular plate close to the end of the base plate.

[0011] Preferably, the shearing mechanism includes a hydraulic rod equidistantly installed on the top of the support seat, the telescopic end of the hydraulic rod passes through the bottom of the support seat and is connected to a fixed block, the bottom of the fixed block is fixedly connected to a fixed plate, one side of the fixed plate is connected to a mounting seat, the internal rotation of the mounting seat is connected to a circular cutter, and the other side of the mounting seat is installed with a driving device 2 for driving the circular cutter to rotate.

[0012] Preferably, the outer side of the top of the fixing plate is fixedly connected to a limiting block of the limiting fixing block, and cutting holes are equidistantly provided at the front and rear ends of one side of the top of the base plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: From the perspective of precise positioning and efficient fixation, the positioning and fixing system of the present invention has outstanding advantages. By controlling the rotation of the bidirectional screw through the servo motor, the two clamping plates can automatically and accurately adjust the long-axis workpiece to the center position between the two positioning seats during the opposite movement. The positioning accuracy far exceeds that of similar equipment. In addition, with the help of the hydraulic plate to drive the clamping seat, the clamping force can be flexibly adjusted according to the size of the workpiece, ensuring that long-axis workpieces of different specifications can be firmly fixed. This not only significantly improves the stability of the workpiece during the shearing process, but also saves a lot of time for manual positioning and fixing, greatly improving production efficiency. This invention adapts to long shaft workpieces of varying sizes, regardless of diameter or length, by adjusting the hydraulic plate's extension and contraction range and the threaded plate's travel distance. When cutting workpieces of the same size continuously, the operator only needs to record the threaded plate's travel distance once, enabling rapid and precise positioning. This makes operation simple and fast. While individual measurements are required for workpieces of varying sizes, the device's ease of operation ensures efficient cutting.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes an embodiment of the present invention based on its overall structure.

[0018] See also Figure 1-6 A metal shaft shearing machine includes a base plate 1, the four corners of the bottom of the base plate 1 are connected to supporting feet, a first groove 2 is opened on one side of the top of the base plate 1 at equal intervals from front to back, and positioning seats 3 for positioning shaft workpieces are installed at both ends of the first groove 2. A second groove 4 is opened in the center direction between two adjacent groups of first grooves 2, and adjustment mechanisms 5 for adjusting the center position of the shaft workpiece are installed at both ends of the second groove 4. A support seat 6 is installed on the other side of the top of the base plate 1, and a shearing mechanism 7 is installed on the inner side of the support seat 6.

[0019] like Figure 1-6 As shown, the interior of the first groove 2 is rotatably connected to a threaded rod 8, and the outer wall of the threaded rod 8 is threadedly connected to two groups of threaded plates 9 with gaps, and the top of the threaded plate 9 is connected to the bottom of the positioning seat 3. Through the existing technology, a servo motor for controlling the rotation of the threaded rod 8 is set inside the base plate 1, which can drive the threaded rod 8 to rotate and thereby drive the two groups of threaded plates 9 to move synchronously in one direction, so that the positioning seat 3 can transport the fixed long-axis workpiece to the area to be processed for easy shearing.

[0020] like Figure 1-6 As shown, slots are provided at the front and rear ends of the top of the positioning seat 3, and a hydraulic plate 10 is installed inside the slot. A pressing seat 11 is connected to the top of the telescopic end of the hydraulic plate 10. After the long-axis workpiece is adjusted to the center position on the positioning seat 3, the pressing seat 11 is driven downward by the telescopic hydraulic plate 10 to press and fix the long-axis workpiece placed on the positioning seat 3. The range of telescopic expansion and contraction can be used to press workpieces of different sizes, so as to avoid offset in subsequent cutting and shearing.

[0021] like Figure 1-6 As shown, the adjusting mechanism 5 includes a bidirectional screw 501 rotatably mounted inside the second groove 4, and threaded seats 502 are installed at both ends of the outer wall of the bidirectional screw 501, and the top of the threaded seat 502 is connected to an arc seat 503, and the top two ends of the arc seat 503 are connected to circular plates 504, and a rotating plate 505 is rotatably connected between the two sets of circular plates 504, and the outer wall of the rotating plate 505 is connected to a connecting block 506, and the other end of the connecting block 506 is connected to a clamping plate 507. When the position of the long-axis workpiece placed on the positioning seat 3 is adjusted, the long-axis workpiece is first placed between the two clamping plates 507, and a servo motor in the prior art is set inside the base plate 1, which is not repeated here. The bidirectional screw 501 can be controlled to rotate, thereby driving the two clamping plates 507 to move toward each other, so that the long-axis workpiece can be clamped and fixed while also driving the workpiece to automatically adjust to the center position between the two positioning seats 3, which is convenient for subsequent shearing work.

[0022] like Figure 1-6 As shown, a connecting rod 12 is provided between the two groups of rotating plates 505 for connection, and a driving device 13 for driving the rotating plate 505 to rotate is installed on one side of the circular plate 504 close to the end of the base plate 1. The driving device 13 can drive the rotating plate on one side to rotate, and then drive the other group of rotating plates 505 to rotate through the connecting rod 12, so that the long axis workpiece in the other direction can be clamped and fixed.

[0023] like Figure 1-6 As shown, the shearing mechanism 7 includes a hydraulic rod 701 equidistantly installed on the top of the support seat 6, the telescopic end of the hydraulic rod 701 passes through the bottom of the support seat 6 and is connected to a fixed block 702, the bottom of the fixed block 702 is fixedly connected to a fixed plate 703, one side of the fixed plate 703 is connected to a mounting seat 704, the internal rotation of the mounting seat 704 is connected to a circular cutter 705, and the other side of the mounting seat 704 is equipped with a driving device 2 706 for driving the circular cutter 705 to rotate. When cutting and shearing the same group of long-axis workpieces of the same size, the staff can first adjust the workpiece to the center between the two positioning seats 3 to cut the workpiece. Make a mark on the position, and then move the corresponding mark to just below the circular cutter 705. At this time, the hydraulic rod 701 moves slowly downward, and the driving device 2 706 drives the circular cutter 705 to rotate to cut the workpiece, and in the shearing process, the axial end of the circular cutter 705 will also grind the cut end of the workpiece, so that the burrs generated on the workpiece after cutting are simultaneously polished and polished, thereby improving work efficiency. When cutting the next group of workpieces of the same size, it is only necessary to control the threaded plate 9 to move the same distance. When cutting workpieces of different sizes, it is only necessary to measure separately and move the corresponding cutting position to just below the cutter.

[0024] like Figure 1-6 As shown, the outer side of the top of the fixing plate 703 is fixedly connected to the limiting block 14 of the limiting fixing block 702, and cutting holes 15 are equidistantly opened at the front and rear ends of one side of the top of the base plate 1.

[0025] Working Principle: When using this metal shaft shearing machine, a servo motor (using established technology, the specific structure and principle of which will not be elaborated here) installed within base plate 1 drives the rotation of threaded rod 8. Because threaded rod 8 is threadedly connected to two sets of threaded plates 9, when threaded rod 8 rotates, the two sets of threaded plates 9 move synchronously in the same direction, guided by the threads. The threaded plates 9 are connected to positioning base 3, enabling positioning base 3 to smoothly transport the secured long shaft workpiece to the processing area, preparing for subsequent shearing operations. After placing a long-axis workpiece on the positioning seat 3, it needs to be adjusted to the center position to ensure accurate shearing. At this point, the long-axis workpiece is placed between the two clamping plates 507. The servo motor inside the base plate 1 is activated, controlling the rotation of the bidirectional screw 501. The bidirectional screw 501 has two sections of threaded rods with opposite rotation directions, which are threadedly connected to the two clamping plates 507. When the bidirectional screw 501 rotates, the two clamping plates 507 move toward each other under the action of the threads. While the clamping plates 507 clamp the long-axis workpiece, the workpiece automatically adjusts to the center position between the two positioning seats 3 due to the symmetrical force of the clamping plates. This greatly improves work efficiency and positioning accuracy, facilitating the smooth execution of subsequent shearing operations. After the long-axis workpiece is centered on the positioning seat 3, it must be clamped to prevent it from shifting during subsequent cutting and shearing. At this point, the hydraulic plate 10 begins operating, extending and retracting, controlled by its internal hydraulic system. This movement drives the clamping seat 11 downward until it firmly clamps the long-axis workpiece against the positioning seat 3. Furthermore, because the hydraulic system precisely controls the extension and retraction of the hydraulic plate 10, it can accommodate workpieces of varying sizes. Whether thin or thick, long-axis workpieces can be stably clamped simply by adjusting the extension and retraction of the hydraulic plate 10. When cutting and shearing long-axis workpieces, if the operation is performed on the same group of workpieces of the same size, the staff can first mark the cutting and shearing position of the first workpiece, and then control the equipment to drive the positioning seat 3 and the workpiece to move through the movement of the threaded plate 9, and move the corresponding mark to directly below the circular cutter 705. At this time, the hydraulic rod 701 starts to work and slowly moves downward through the hydraulic system. The hydraulic rod 701 is connected to the second device 706, and then drives the second device 706 to drive the circular cutter 705 to rotate at high speed to cut and shear the workpiece. It is worth mentioning that in the process of the circular cutter 705 cutting the workpiece, its axial end also has a grinding function, which can grind the end of the workpiece after cutting. In this way, while the cutting is completed, the burrs generated after the workpiece is cut can also be polished synchronously, avoiding the need for a separate deburring process later, greatly improving work efficiency. When the next group of workpieces of the same size are cut, the staff only needs to control the threaded plate 9 to move the same distance again according to the previously recorded distance data of the threaded plate 9, and the workpiece can be accurately moved to the bottom of the circular cutter 705 for cutting, which is very convenient. When cutting workpieces of different sizes, individual measurements are required because there's no way to reference the positioning data of previously used workpieces of the same size. The worker uses a measuring tool to accurately determine the cutting position on the workpiece. Then, by manipulating the equipment, the worker adjusts the movement of the threaded plate 9 to position the corresponding cutting position directly below the circular cutter 705. Following the aforementioned cutting process, the hydraulic rod 701 and circular cutter 705 are activated to cut the workpiece, ensuring smooth and precise cutting.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
