Description

Technical Field

[0001] The present invention relates to the field of cutting facilities, in particular to a forging cutting device with adjustable cutting angle. Background Art

[0002] Forgings are metal products with defined shapes, dimensions, and mechanical properties, achieved through the forging process, where external forces are applied to a metal blank to cause plastic deformation. Forged workpieces are mostly blanks, requiring finishing, such as cutting grooves in the workpiece surface, to achieve a workpiece that meets standards.

[0003] However, when processing some special-shaped workpieces, it is necessary to cut grooves with opposite inclinations on the surface. At this time, due to the special shape of the workpiece, the traditional fixture cannot accurately position it, resulting in deviations in the angles of the cut grooves during subsequent cutting, which seriously affects the cutting accuracy. At the same time, because the two grooves are inclined in opposite directions, the cutting process requires re-clamping the workpiece to adjust the position before the two grooves can be cut. The process is quite time-consuming, resulting in low cutting efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0026] like Figures 1-8The forging cutting device with adjustable cutting angle shown in the figure includes a base 1, a center column 30 is rotatably installed on the front upper end of the base 1, and a cutting table 10 is embedded in the upper end of the center column 30. The cutting table 10 serves to support the workpiece 36, and a cutting piece is tiltedly arranged on the rear upper end of the base 1. A positioning column 20 is extended from the rear upper end of the cutting table 10, and two triangular blocks 21 are symmetrically extended from the front upper end of the cutting table 10. The positioning column 20 and the triangular block 21 can accurately position the workpiece 36 so that the angle of the groove 37 to be cut on the workpiece 36 is the same as the inclination angle of the cutter 5 to ensure that the angle of the groove 37 will not deviate after the cutter 5 cuts. The size of the positioning column 20 and the triangular block 21 is adapted to the size of the through hole on the workpiece 36, which can ensure that they fit the through hole of the workpiece 36 to avoid shaking after insertion, which affects the positioning. The center line of the center column 30 is aligned with the workpiece 36. The intersection of the extension lines of the two grooves 37 on the workpiece 36 is aligned, which can ensure that when the workpiece 36 on the cutting table 10 rotates around the center column 30, the required cutting position of the workpiece 36 is aligned with the cutter 5. Arc plugs 22 extend on both sides of the cutting table 10, and the center of the arc plug 22 is aligned with the center line of the center column 30. The upper end of the base 1 is provided with two arc groove seats 8 in a circular array with the center column 30 as the center. The arc plugs 22 and the arc groove seat 8 serve to limit the rotating cutting table 10 so that after rotation, the required cutting position of the workpiece 36, that is, the position of the groove 37, can be aligned with the cutter 5. At the same time, the inclination angles of the two are also the same to avoid deviation. The two arc groove seats 8 are arranged in opposite directions, and a locking member is provided on the arc groove seat 8. One of the arc plugs 22 is inserted into the front arc groove seat 8, and a fixing member is installed at the front end of the cutting table 10.

[0027] A support 7 is fixedly mounted on the lower end of the arc-shaped slot seat 8 , and the lower end of the support 7 is fixed to the base 1 . The support 7 plays a role in supporting and fixing the arc-shaped slot seat 8 .

[0028] The cutting piece includes a bearing seat 2 fixedly mounted on the rear part of the upper end of the pedestal 1, a servo push cylinder 3 is fixedly mounted on the front end of the bearing seat 2, the bearing seat 2 plays the role of supporting the servo push cylinder 3, the output end of the servo push cylinder 3 is fixedly mounted with a propulsion seat 14, the servo push cylinder 3 plays the role of obliquely propulsing the cutter 5, and two guide rods 15 are symmetrically extended on the side of the propulsion seat 14, the guide rods 15 play the role of obliquely guiding the cutter 5, the bearing seat 2 is slidably mounted on the outer surface of the guide rod 15, and the upper end of the propulsion seat 14 is fixedly mounted with an extension rod 15. The end of the outgoing frame 4 is fixedly mounted with a motor 11, and the output end of the motor 11 is coaxially fixedly mounted with a cutter 5. The motor 11 drives the cutter 5 to rotate for cutting. The guide rod 15, the servo push cylinder 3, and the cutter 5 are all inclined. The inclination angle of the guide rod 15, the servo push cylinder 3, and the cutter 5 is the same as the inclination angle of the groove 37 on the workpiece 36, which enables the cutter 5 to be obliquely advanced and cut based on the inclination angle of the groove 37, thereby ensuring that the inclination angle of the cut groove 37 meets the standard and will not deviate.

[0029] The fixing part includes a bending frame 9 elastically mounted on the front end of the cutting table 10, a pressure claw 27 is rotatably mounted at the front edge of the upper end of the cutting table 10, and two pressure claw frames 29 are symmetrically rotatably mounted on the upper front end of the pressure claw 27. The end of the pressure claw frame 29 is rotatably connected to the bending frame 9, and the bending frame 9 moves downward to allow the pressure claw frame 29 on the bending frame 9 to move to push the pressure claw 27 to press on the workpiece 36. The rear end of the bending frame 9 is fixedly mounted with a ring sleeve 31, and the ring sleeve 31 is slidably mounted on the outer surface of the center column 30. The design of the ring sleeve 31 and the semicircular ring 19 can ensure that after the cutting table 10 is rotated, the bending frame 9 can still be driven to move downward. The rear of the cutting table 10 is tilted with a slope frame 16, and the inclination angle of the slope frame 16 is consistent with the guide rod The inclination angle of 15 is the same, which can adapt to the oblique propulsion trajectory of the cutter 5. The ramp frame 16 is elastically connected to the base 1, and an extension frame 12 is extended from the rear end of the propulsion seat 14. The end of the extension frame 12 is equipped with a frame wheel 13, and the frame wheel 13 is aligned with the ramp frame 16. The extension frame 12 plays a role in carrying the frame wheel 13. A semicircular ring 19 is fixedly installed at the front end edge of the ramp frame 16. The semicircular ring 19 fits the outer surface of the center column 30. The semicircular ring 19 is pressed on the ring sleeve 31, and the extension frame 12 is pushed obliquely. At this time, the frame wheel 13 on the extension frame 12 will roll on the slope of the ramp frame 16 to drive the ramp frame 16 to move downward, thereby driving the semicircular ring 19 to move downward, so as to press the ring sleeve 31 downward, thereby driving the bending frame 9 to move downward.

[0030] The two ends of the No. 2 return spring 26 are respectively fixed to the upper end of the limit post 28 and the upper end of the rod sleeve 25, and the limit post 28 plays the role of preventing the No. 2 return spring 26 from bending. The No. 2 return spring 26 can drive the downwardly moved bending frame 9 to reset, and the lower end of the limit post 28 is coaxially inlaid with a limiting cap 24. The limiting cap 24 is fitted to the lower end of the rod sleeve 25, and the limiting cap 24 can position the reset height of the bending frame 9.

[0031] Two shell columns 17 are fixedly installed at the lower end of the slope frame 16, and a carrier shell 6 is slidably installed at the lower part of the shell column 17. The shell column 17 and the carrier shell 6 guide the slope frame 16. The carrier shell 6 is embedded in the upper end of the base 1. A No. 1 return spring 18 is fixedly installed on the inner bottom surface of the carrier shell 6. The upper end of the No. 1 return spring 18 is fixed to the shell column 17, and the No. 1 return spring 18 serves to reset the downward-moving slope frame 16.

[0032] The locking member includes a positioning bend 34 installed at the upper end of the arc-shaped slot seat 8. The end of the positioning bend 34 on the front arc-shaped slot seat 8 abuts against the inner wall of one of the arc-shaped plugs 22. The positioning bend 34 can be inserted into the arc-shaped plug 22 to prevent the arc-shaped plug 22 from moving, thereby fixing the arc-shaped plug 22 in the arc-shaped slot seat 8. A locking spring 33 is fixedly installed at the lower end of the positioning bend 34. The locking spring 33 is connected to the arc-shaped slot seat 8. The locking spring 33 can push the positioning bend 34 to insert the positioning bend 34 into the arc-shaped plug 22.

[0033] A connecting shaft 35 is rotatably installed near the middle of the positioning bend 34, and the connecting shaft 35 is fixed to the arc-shaped slot seat 8. The connecting shaft 35 serves to rotate the positioning bend 34. An extending cap 32 extends from the end of the arc-shaped slot seat 8, and the lower end of the locking spring 33 is fixed to the extending cap 32. The extending cap 32 serves to support the locking spring 33.

[0034] During cutting, the workpiece 36 is placed on the cutting table 10. At this time, the triangular block 21 and the positioning column 20 that match the through hole on the workpiece 36 will be correspondingly inserted into the through hole on the workpiece 36 to accurately position the workpiece 36 so that the part to be cut on the workpiece 36 is aligned with the cutter 5, that is, the angle of the groove 37 to be cut on the workpiece 36 is the same as the inclination angle of the cutter 5. Then, the servo push cylinder 3 is pushed forward by the cutter 5 driven by the motor 11. At this time, the guide rod 15 slides on the bearing seat 2 to guide the cutter 5 so that the cutting The knife 5 can be pushed obliquely, that is, pushed at the same inclination angle as the groove 37. At the same time, the extension frame 12 will be pushed obliquely synchronously. At this time, the frame wheel 13 on the extension frame 12 will roll on the slope of the ramp frame 16 to drive the ramp frame 16 to move downward, thereby driving the semi-circular ring 19 to move downward to press the ring sleeve 31 downward, thereby driving the bending frame 9 to move downward, allowing the pressure claw frame 29 on the bending frame 9 to move to push the pressure claw 27 to press on the workpiece 36, so that it is fixed by itself, and then the cutter 5 continues to be pushed obliquely to contact the workpiece 36 , in order to cut a groove 37 of the required tilt angle on the workpiece 36. During this process, the frame wheel 13 rolls on the plane of the ramp frame 16 to keep the workpiece 36 fixed. After the groove 37 on one side of the workpiece 36 is cut, the servo push cylinder 3 moves in the reverse direction to drive the cutter 5 to reset, and then presses the positioning bend frame 34 on the front arc groove seat 8 to make the positioning bend frame 34 tilted around the connecting shaft 35 and disengage from the arc plug 22, so that the workpiece 36 on the cutting table 10 can rotate around the center column 30, that is, the workpiece 36 can rotate with the center column 30 as the center. The workpiece 36 rotates around the intersection of the extension lines of the two grooves 37. When the other arc plug 22 is inserted into the rear arc groove seat 8 and fixed by the positioning bend 34 on the rear arc groove seat 8, the part to be cut on the other side of the workpiece 36 is just aligned with the cutter 5, that is, the angle of the groove 37 to be cut on the other side of the workpiece 36 is the same as the inclination angle of the cutter 5. Then the servo push cylinder 3 drives the cutter 5 obliquely forward again for cutting, thereby adjusting the cutting angle to cut out two grooves 37 with opposite inclinations on the workpiece 36.
