Description

Technical Field

[0001] This utility model relates to the field of metal cutting and processing technology, and in particular to a cutting device. Background Technology

[0002] With the continuous development of technology in the field of metal processing and manufacturing, the processing requirements for blanks required for the manufacture of various precision parts are increasing day by day.

[0003] In existing technologies, shearing of workpieces typically employs shearing machine tools with fixed cutting tools. The positions of the cutting tool and the machine bed are relatively fixed. When processing workpieces of different specifications and with varying processing requirements, operators rely primarily on their experience to adjust the workpiece's placement to achieve a suitable shearing angle. However, ensuring the sheared section is perpendicular to the workpiece's axis is crucial for guaranteeing processing quality. Deviations in the shearing angle can lead to a tilted section, increased burrs, or difficulties in subsequent processing.

[0004] In summary, the existing shearing machine tools mainly have the following problems:

[0005] (1) It is necessary to rely on manual experience to adjust the position of the workpiece, which makes it difficult to ensure that the angle between the workpiece and the shearing tool is accurate every time it is sheared, resulting in low processing accuracy and poor product consistency.

[0006] (2) Manual adjustments are time-consuming and labor-intensive, resulting in low production efficiency;

[0007] (3) The processed products are difficult to meet the requirements of high-precision use. Utility Model Content

[0008] Therefore, it is necessary to address the problems of low processing accuracy, poor product consistency, low production efficiency, and difficulty in meeting high-precision application requirements of existing shearing machine tools, and to provide a high-precision pipe shearing equipment and its working method.

[0009] The technical solution adopted in this utility model is as follows:

[0010] A cutting device includes a base, a rotating seat is mounted on the top of the base through a first rotary drive mechanism, and a frame is mounted on the top of the base through a second rotary drive mechanism. The rotating seat is arranged between the frame and the base and supports the frame. A shearing mechanism is mounted on the frame, and the shearing mechanism shears the workpiece under the drive of the shearing drive mechanism.

[0011] The first rotary drive mechanism drives the rotating seat to rotate relative to the base, and the second rotary drive mechanism drives the frame to move in a straight line in the horizontal direction relative to the base, thereby adjusting the angle between the shearing center of the frame and the base, and further adjusting the angle between the shearing center of the frame and the workpiece feeding direction.

[0012] As a further improvement to the above technical solution:

[0013] The first pressing mechanism and the second pressing mechanism are respectively installed on one side wall of the frame, and an auxiliary pressing mechanism is installed on the other side wall of the frame. The auxiliary pressing mechanism is arranged along the length of the frame and is used to support the workpiece when the shearing mechanism shears the workpiece.

[0014] The first and second pressing mechanisms are arranged at intervals relative to each other along the length of the frame. The first and second pressing mechanisms are used to clamp the workpiece when the shearing mechanism shears the workpiece.

[0015] The structure of the first pressing mechanism is as follows: it includes a pressing cylinder fixed on the frame, the output end of the pressing cylinder is connected to a first pressing block, and the working end face of the first pressing block is provided with an inward concave arc surface corresponding to the outer circumference of the workpiece;

[0017] The auxiliary pressing mechanism has the following structure: it includes a follower cylinder fixed on the frame, and the output end of the follower cylinder is connected to the auxiliary pressing block.

[0018] The structure of the first rotary drive mechanism is as follows: it includes a first hydraulic cylinder hinged to the top of the base, and the output end of the first hydraulic cylinder is hinged to the rotary seat through a first connecting shaft.

The end of the second connecting shaft extends into the machine frame and is rotatably engaged with the machine frame.

[0020] The shearing mechanism comprises a fixed cutter head fixed on the frame and a shearing slider slidably installed inside the frame. A movable cutter head corresponding to the fixed cutter head is fixed on the shearing slider. Driven by the shearing drive mechanism, the shearing slider moves linearly along the length of the frame, thereby causing the movable cutter head to move linearly closer to or away from the fixed cutter head, thus achieving the shearing of the workpiece.

[0021] The shearing drive mechanism comprises a gear shaft rotatably mounted on the frame and a cam shaft rotatably mounted on the frame.

[0022] A flywheel is fixed at one end of the gear shaft, and several gear teeth are arranged circumferentially at the other end of the gear shaft. A main gear is fixed at one end of the cam shaft, and the main gear is meshed with the gear teeth of the gear shaft.

[0023] It also includes a shearing motor, the output end of which is connected to a pulley, and a transmission belt is installed between the pulley and the flywheel;

[0024] The outer circumferential surface of the camshaft is fitted with the shearing slider. The shearing motor drives the pulley to rotate, which in turn drives the flywheel to rotate via the transmission belt. This drives the gear shaft to rotate, which in turn drives the main gear to rotate. The rotating main gear drives the camshaft to rotate, thereby driving the shearing slider to move.

[0025] A distance measuring mechanism is installed at the other end of the camshaft, which is used to monitor the moving distance of the shearing slider.

[0026] The frame is installed by a shearing slide rail assembly and a shearing slider. The shearing slide rail assembly includes two shearing slide rails spaced apart from top to bottom along the height direction of the frame. Several adjustment grooves are provided on the bottom end face of the lower shearing slide rail, and the inner wall of each adjustment groove is provided with an inclined surface.

[0032] This utility model has a compact and reasonable structure and is easy to operate. By setting up a rotating base, a frame, a first rotating drive mechanism, and a second rotating drive mechanism, it can drive the shearing mechanism to rotate relative to the base, thereby adjusting the angle between the shearing center of the shearing mechanism and the workpiece. This ensures that the cross-section of the workpiece after shearing is perpendicular to its axis, effectively improving processing accuracy and ensuring the consistency and quality of the processed products. At the same time, by setting up the shearing drive mechanism and the shearing mechanism, fully automatic processing can be achieved, effectively improving production efficiency.

[0053] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0054] The structure and function of this utility model are as follows:

[0055] like Figures 1-9As shown, a cutting device includes a base 1. A rotating seat 2 is mounted on the top of the base 1 via a first rotary drive mechanism 8. A frame 3 is also mounted on the top of the base 1 via a second rotary drive mechanism 9. The rotating seat 2 is arranged between the frame 3 and the base 1 and supports the frame 3. A shearing mechanism 6 is mounted on the frame 3. The shearing mechanism 6 shears the workpiece under the drive of the shearing drive mechanism 5. The first rotary drive mechanism 8 drives the rotating seat 2 to rotate relative to the base 1, and the second rotary drive mechanism 9 drives the frame 3 to move linearly in the horizontal direction relative to the base 1, thereby adjusting the angle between the shearing center of the frame 3 and the base 1, and further adjusting the angle between the shearing center of the frame 3 and the workpiece feeding direction. By setting up a rotating base 2, a frame 3, a first rotary drive mechanism 8, and a second rotary drive mechanism 9, the shearing mechanism 6 can be driven to rotate relative to the base 1, thereby adjusting the angle between the shearing center 6 of the shearing mechanism and the workpiece. This ensures that the cross-section of the workpiece after shearing is perpendicular to its axis, effectively improving processing accuracy and guaranteeing the consistency and quality of the processed products. Simultaneously, by setting up the shearing drive mechanism 5 and the shearing mechanism 6, fully automatic processing can be achieved, effectively improving production efficiency. The cutting device of this utility model is also equipped with a hydraulic station to provide hydraulic oil to the hydraulic components within the equipment.

[0056] A first pressing mechanism 11 and a second pressing mechanism 12 are respectively installed on one side wall of the frame 3, and an auxiliary pressing mechanism 13 is installed on the other side wall of the frame 3. The auxiliary pressing mechanism 13 is arranged along the length of the frame 3 and is used to support the workpiece when the shearing mechanism 6 shears the workpiece. The first pressing mechanism 11 and the second pressing mechanism 12 are arranged at intervals relative to each other along the length of the frame 3 and are used to clamp the workpiece when the shearing mechanism 6 shears the workpiece. By setting the first pressing mechanism 11 and the second pressing mechanism 12, shaking of the workpiece during shearing can be avoided, effectively improving the stability of the shearing process.

[0057] In this invention, along the direction from workpiece feeding to discharge, the first pressing mechanism 11 and the second pressing mechanism 12 are arranged at the front end of the fixed cutter head 602 and the movable cutter head 603. An auxiliary pressing mechanism 13 is arranged at the rear end of the fixed cutter head 602. The auxiliary pressing block 1301 corresponds to the movable cutter head 603. During the translational movement of the movable cutter head 603 relative to the fixed cutter head 602, the auxiliary pressing block 1301 moves backward with the movement of the movable cutter head 603 under the action of the follower cylinder 1302, avoiding interference with the movement of the movable cutter head 603, and further improving the flatness of the workpiece cutting surface and increasing the cutting accuracy.

[0058] The first pressing mechanism 11 has the following structure: it includes a pressing cylinder 1102 fixed on the frame 3, the output end of the pressing cylinder 1102 is connected to a first pressing block 1101, and the working end face of the first pressing block 1101 is provided with an inner concave arc surface 1103 corresponding to the outer circumferential surface of the workpiece; the second pressing mechanism 12 has the following structure: it includes a pressing fixing seat 1203 fixed on the frame 3, and the second pressing block 1201 is installed on the pressing fixing seat 1203 in cooperation with the adjusting screw 1202. The linear distance between the second pressing block 1201 and the pressing fixing seat 1203 is adjusted by rotating the adjusting screw 1202 in the horizontal direction; the auxiliary pressing mechanism 13 has the following structure: it includes a follower cylinder 1302 fixed on the frame 3, and the output end of the follower cylinder 1302 is connected to the auxiliary pressing block 1301. When shearing the workpiece, the movable cutter head 603 moves forward in a horizontal linear motion, and the working end face of the auxiliary pressure block 1301 is in contact with the workpiece. Simultaneously, under the action of the follower cylinder 1302, the auxiliary pressure block 1301 moves backward in a horizontal linear motion along with the forward movement of the movable cutter head 603. By setting the concave arc surface 1103, the first pressure block 1101 can be in contact with the outer circumferential surface of the workpiece, improving the clamping effect of the first pressure mechanism 11 and the second pressure mechanism 12 on the workpiece.

[0059] The first rotary drive mechanism 8 has the following structure: it includes a first hydraulic cylinder 801 hinged to the top of the base 1, and the output end of the first hydraulic cylinder 801 is hinged to the rotating seat 2 via a first connecting shaft 802; the second rotary drive mechanism 9 has the following structure: it includes a second hydraulic cylinder 901 hinged to the base 1, and the output end of the second hydraulic cylinder 901 is hinged to a transverse slider 903. The transverse slider 903 is slidably engaged with the base 1 via a transverse slide rail assembly. The transverse slide rail assembly includes two parallel and spaced transverse slide rails 904. A second connecting shaft 902 arranged vertically is fitted on the transverse slider 903. The end of the second connecting shaft 902 extends into the frame 3 and is rotatably engaged with the frame 3. When the first hydraulic cylinder 801 extends or retracts, it drives the rotating seat 2 to rotate around the second connecting shaft 902 via the first connecting shaft 802.

[0060] The second cylinder 901 extends or retracts, and drives the second connecting shaft 902 to reciprocate linearly in the horizontal direction through the transverse slider 903, thereby driving the shearing mechanism 6 to reciprocate linearly in the horizontal direction through the second connecting shaft 902.

[0061] In this invention, the angle between the arrangement direction of the first hydraulic cylinder 801 and the arrangement direction of the second hydraulic cylinder 901 is not equal to 90°.

[0062] The rotating base 2 includes two L-shaped supports symmetrically arranged opposite the frame 3. The two L-shaped supports jointly support the frame 3. A pointer is fixed on one of the L-shaped supports. The pointer corresponds to a scale fixed on the top of the base 1 and can indicate the rotation angle of the frame 3.

[0063] Several tensioning cylinders 14 are installed between the rotating seat 2 and the base 1. Several sliding grooves 7 are opened on the end face of the rotating seat 2. A pull rod is installed in each sliding groove 7. A pressure plate is installed on the outer circumference of each pull rod. Each pressure plate is arranged on the top of the rotating seat 2. Each pull rod is connected to the output end of the tensioning cylinder 14. Each tensioning cylinder 14 is fixed on the base 1. When the shearing mechanism 6 rotates, the tensioning cylinder 14 extends at the same time. After the shearing mechanism 6 has rotated, the tensioning cylinder 14 retracts at the same time, thereby driving the corresponding pressure plate through the corresponding pull rod to press the rotating seat 2 onto the base 1, thus fixing the shearing mechanism 6. By setting the tensioning cylinder 14, the shearing mechanism 6 can be locked and fixed after it is adjusted into place, thereby ensuring the stability of the shearing operation.

[0064] The shearing mechanism 6 comprises a fixed cutter head 602 fixed to the frame 3 and a shearing slider 601 slidably mounted inside the frame 3. A movable cutter head 603 corresponding to the fixed cutter head 602 is fixed on the shearing slider 601. Driven by the shearing drive mechanism 5, the shearing slider 601 moves linearly along the length of the frame 3, thereby causing the movable cutter head 603 to move linearly closer to or away from the fixed cutter head 602, thus achieving the shearing of the workpiece. By setting up the shearing mechanism 6, it can efficiently shear the workpiece in the horizontal direction based on the fixed cutter head 602 and the movable cutter head 603, thereby shearing the workpiece into short bars of a certain length.

[0065] The shearing mechanism 6 shears the workpiece under the drive of the shearing drive mechanism 5. The shearing drive mechanism 5 has the following structure: it includes a gear shaft 505 rotatably mounted on the frame 3 and a cam shaft 506 rotatably mounted on the frame 3; one end of the gear shaft 505 is fixed to a flywheel 503, and the other end of the gear shaft 505 is provided with several gear teeth in the circumferential direction; one end of the cam shaft 506 is fixed to a main gear 504, and the main gear 504 is meshed with the gear teeth of the gear shaft 505; it also includes a shearing motor 501, the output end of which is connected to a pulley 502, and a transmission belt is installed between the pulley 502 and the flywheel 503; the outer circumferential surface of the cam shaft 506 is fitted with the shearing slider 601, the shearing motor 501 drives the pulley 502 to rotate, which drives the flywheel 503 to rotate through the transmission belt, thereby driving the gear shaft 505 to rotate, which in turn drives the main gear 504 to rotate, and the rotating main gear 504 drives the cam shaft 506 to rotate, thereby driving the shearing slider 601 to move. A clutch and brake are also installed on the outer circumference of the gear shaft 505, which can control the rotation and stop of the gear shaft 505 according to production needs while the shearing motor 501 maintains torque output, thereby controlling the start and stop of the shearing mechanism 6.

[0066] A bearing housing is installed on the outside of the gear shaft 505. The bearing housing is fixed on the frame 3 to support the gear shaft 505 and protect the gear teeth of the gear shaft 505. An oil collection box is installed below the main gear 504 to collect the lubricating oil of the main gear 504 and ensure the cleanliness of the production site.

[0067] like Figure 6 As shown, the camshaft 506 has the following structure: it includes a first shaft segment 5061, a second shaft segment 5062, and a third shaft segment 5063 arranged sequentially. The first shaft segment 5061 and the third shaft segment 5063 are arranged concentrically, while the second shaft segment 5062 is arranged eccentrically relative to the first shaft segment 5061 and the third shaft segment 5063. The diameter of the second shaft segment 5062 is larger than the diameter of the first shaft segment 5061, and the diameter of the second shaft segment 5062 is larger than the diameter of the third shaft segment 5063. The first shaft segment 5061 is used to mate with the main gear 504, and the second shaft segment 5062 is used to mate with the shearing slider 601. The shearing slider 601 has a third mounting hole 605, through which it mates with the second shaft segment 5062. A bearing bush 507 is fitted onto the outer circumference of the third shaft segment 5063.

[0068] By setting the second shaft segment 5062, the camshaft 506 can drive the shearing slider 601 to generate a horizontal motion component during rotation. The frame 3 includes two spaced outer plates. The shearing slider 601 is installed between the two outer plates through a shearing slide rail assembly. The two outer plates are simultaneously provided with a first mounting hole 16 for mounting with the camshaft 506 and a second mounting hole 17 for mounting with the gear shaft 505. The shearing slide rail assembly includes two shearing slide rails 604 spaced from top to bottom along the height direction of the frame 3. Several adjusting grooves 606 are provided on the bottom end face of the lower shearing slide rail 604. The inner wall of each adjusting groove 606 is provided with an inclined surface. Several receiving grooves are provided in the frame 3. The receiving grooves and adjusting grooves 606 are arranged one-to-one. An installation space is formed between each adjusting groove 606 and the corresponding receiving groove. A pin element is installed in each installation space.

[0069] The structure of a single pin element is as follows: it includes an adjusting pin 607, an adjusting pin sleeve 608 is fitted on the outer circumference of the adjusting pin 607, the adjusting pin sleeve 608 is fixed to the outer wall of the frame 3, a central hole is opened in the middle of the adjusting pin sleeve 608, and annular limiting steps 611 are arranged at intervals along the axial direction in the central hole. An adjusting spring 609 is fitted between the two limiting steps 611 and is sleeved on the outer circumference of the adjusting pin 607. An adjusting nut 610 is fitted at the end of the adjusting pin 607, and a chamfered surface 612 corresponding to the inclined surface is provided on the outer circumference of the adjusting pin 607. By setting the adjusting pin 607, adjusting pin sleeve 608 and adjusting spring 609, the vertical displacement of the shearing slider 601 during its movement can be compensated. The operator can manually adjust the gap between the shearing slider 601 and the upper and lower shearing slide rails 604 in advance. After the adjustment is in place, the adjusting nut 610 is turned to lock the adjusting pin 607, so that the shearing slider 601 can drive the movable cutter head 603 to move closer to the fixed cutter head 602.

[0070] A distance measuring mechanism 10 is mounted on the other end of the camshaft 506. The distance measuring mechanism 10 is used to monitor the movement distance of the shearing slider 601. The distance measuring mechanism 10 includes a first synchronous pulley 1001 fixed to the end of the camshaft 506 and a mounting base 1004 fixed to the frame 3. A rotating shaft is rotatably mounted on the mounting base 1004. An encoder 1005 is connected to the end of the rotating shaft. A second synchronous pulley 1002 is mounted on the outer circumference of the rotating shaft. A synchronous belt 1003 is mounted between the second synchronous pulley 1002 and the first synchronous pulley 1001. By setting the encoder 1005, the horizontal displacement distance of the shearing slider 601 can be monitored based on the number of rotations and rotation angle of the camshaft 506, thereby monitoring the distance between the movable cutter head 603 and the fixed cutter head 602, and thus realizing fully automatic shearing.

[0071] A length-fixing mechanism 15 is mounted on the frame 3, and a protective cover 4 is mounted on the outside of the length-fixing mechanism 15 to protect it; for example Figure 9 As shown, the structure of the length-fixing mechanism 15 is as follows: it includes a connecting seat 1501 fixed on the frame 3, a length-fixing motor 1502 fixed on the connecting seat 1501, the output end of the length-fixing motor 1502 is connected to the length-fixing lead screw 1503 rotatably mounted on the connecting seat 1501 through the length-fixing transmission assembly 1504, a movable seat 1505 is fitted on the outer circular surface of the length-fixing lead screw 1503, a length-fixing cylinder 1506 arranged in the horizontal direction is fixed on the movable seat 1505, and the output end of the length-fixing cylinder 1506 is connected to the stop rod 1507; the length-fixing motor 1502 drives the length-fixing lead screw 1503 to rotate through the length-fixing transmission assembly 1504, thereby causing the movable seat 1505 to move linearly along the axial direction of the length-fixing lead screw 1503, and thus driving the stop rod 1507 to move linearly. By setting a length-fixing mechanism 15, the center of the end face of the stop rod 1507 faces the edge of the workpiece, which can be adjusted according to production requirements. By setting a length-fixing motor 1502, a length-fixing lead screw 1503, a movable seat 1505, and a length-fixing cylinder 1506, the center of the end face of the stop rod 1507 can be moved closer to or further away from the cutting center. The straight-line distance between the center of the end face of the stop rod 1507 and the cutting center can be adjusted according to production needs to ensure that the length of the cut product meets the quality requirements.

[0072] The working process of this utility model is as follows:

[0073] First, the first rotary drive mechanism 8 and the second rotary drive mechanism 9 drive the shearing mechanism 6 to rotate relative to the base 1 into position. After rotating into position, all the tensioning cylinders 14 retract, thereby pressing the rotating seat 2 onto the base 1 through the corresponding pressure plate, thus fixing the position of the shearing mechanism 6 so that the shearing mechanism 6 can be adjusted into position.

[0074] After the shearing mechanism 6 is adjusted to the correct position, according to the specifications of the workpiece and product requirements, the fixed length motor 1502 drives the movable seat 1505 to move linearly in the horizontal direction through the fixed length lead screw 1503, thereby adjusting the fixed length cylinder 1506 to the correct position.

[0075] Subsequently, the length-fixing cylinder 1506 extends, thereby driving the stop rod 1507 to extend, in order to control the length of the workpiece after shearing. After the stop rod 1507 is adjusted into place, the workpiece is conveyed by the external conveying equipment until the round surface of one end of the workpiece contacts the stop rod 1507. The external conveying equipment stops conveying forward, and the pressing cylinder 1102 extends, driving the first pressing block 1101 to make a linear movement in the horizontal direction close to the second pressing block 1201, thereby clamping the workpiece.

[0076] The shearing drive mechanism 5 drives the camshaft 506 to rotate. At the same time, under the action of the pin element, the shearing slider 601 drives the movable cutter head 603 to make a linear motion in the horizontal direction close to the fixed cutter head 602, thereby shearing the workpiece.

[0077] At the same time, the auxiliary pressing block 1301 retracts with the shearing action of the movable cutter head 603. While avoiding interference with the action of the movable cutter head 603, it can clamp the workpiece through the auxiliary pressing mechanism 13 to ensure that the workpiece cross-section is flat and the cut is perpendicular to the workpiece axis.

[0078] Finally, the sheared workpiece is unloaded, completing one shearing cycle. This process is repeated until the shearing task is finished.

[0079] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
