Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in FIG. 1, the steel ball forging production method comprises the following steps:
s1, preparing a steel bar blank;
s2, forging and pressing the steel bar blank in three directions of the three-dimensional space to obtain a steel ball, wherein two phases in the three directions are vertical, and the first forging and pressing are along the axial direction of the steel bar blank;
and S3, performing heat treatment on the steel ball.
In S1, preparing the steel rod blank includes heating the steel rod blank to a forging temperature of 1120 ± 5 ℃.
S2 includes turning the steel ball by at least one manipulator to reduce labor and improve efficiency and safety.
In the embodiment, two manipulators are used for overturning the steel ball, only one manipulator needs to be used when the first forging pressure is switched to the second forging pressure because the steel ball only needs to be rotated by 90 degrees, and the other manipulator needs to be used when the second forging pressure is switched to the third forging pressure because the steel ball needs to be rotated by 90 degrees after the clamping point of the steel ball is changed. The second manipulator is placed near a new clamping point in advance, and after the second forging and pressing is finished, the second manipulator can be started to clamp the steel ball immediately, so that the time for rotating the steel ball is shortened, the temperature for cooling the steel ball is reduced, and the quality of the steel ball is improved.
In S3, the heat treatment of the steel ball includes quenching at a temperature of 950 ± 3 ℃.
As shown in fig. 2, the robot 2 is used for production, thereby improving safety and production efficiency.
In fig. 2, a gripper 3 is mounted on the manipulator 2 for assisting in taking the steel bar billet 12 heated to the forging temperature.
As shown in fig. 3, the manipulator 2 grips the steel bar billet 12 and then conveys the steel bar billet 12 to the forging die 1.
The forging die 1 includes an upper die 4 and a lower die 5. The upper mould tool 4 has an upper socket 6 (actually part of a sphere, schematically illustrated as a circular arc for ease of viewing) and the lower mould tool 5 has a lower socket 7.
The lower die 5 is fixed, the upper die 4 is pressed downward, the steel bar blank 12 is extruded, the steel bar blank 12 is deformed and filled in the upper ball socket 6 and the lower ball socket 7, this is the first forging, and the steel bar blank 12 is deformed into a blank with the shape shown in b in fig. 4 after the first forging. The direction of the first forging is the direction of the line l in a of fig. 4, i.e. the axis of the steel bar blank.
In this example, the upper ball socket 6 and the lower ball socket 7 are not completely hemispherical, the upper ball socket 6 and the lower ball socket 7 are slightly smaller than the hemispherical surface, and the depth of the upper ball socket 6 and the lower ball socket 7 is about 4/5 of the radius of the steel ball. And when the stamping stroke of the upper die 4 to the lower die 5 is finished, the upper die 4 and the lower die 5 are away from each other by a certain distance, so that the upper ball socket 6 and the lower ball socket 7 form a part of the same sphere to ensure the roundness of the steel ball. After the first forging, a flange-type bulge is formed at about the equator of the intermediate shape b of the blank in fig. 4, and the flange-type bulge is to be further compacted.
The depths of the upper ball socket 6 and the lower ball socket 7 are smaller than the radius of the steel ball to be manufactured, so that on one hand, the bad phenomena of convex lines and the like are not easy to form on the surface of the steel ball, and the steel ball is favorably compacted; on the other hand, demolding is facilitated due to the reduction in the area of the envelope of the upper socket 6 or the lower socket 7.
In this example, the depth of the upper ball socket 6 and the lower ball socket 7 is smaller than the radius of the steel ball to be manufactured, in other embodiments, the depth of only the upper ball socket 6 or only the lower ball socket 7 may be smaller than the radius of the steel ball to be manufactured, and the depth of the other ball socket may be equal to the radius of the steel ball to be manufactured.
After the first forging, as shown in fig. 4, the steel ball is rotated 90 ° around the horizontal axis m in b, and the second forging is performed, still by pressing down the upper die 4, and the blank shape shown in fig. 4 c is formed after the second forging.
After the second forging pressing is finished, the blank is rotated by 90 degrees around the horizontal axis n in the c, and third forging pressing is carried out, and the third forging pressing is also realized by downward stamping of the upper die 4. Finally, a steel ball d is manufactured.
In this example, two lines of l, m, and n are perpendicular to each other, so that two phases are perpendicular to the three pressing directions of the blank (in this example, the pressing directions of the blank are switched because the blank is rotated although the upper die 4 presses downward).
After three times of forging and pressing, the upper ball socket 6 and the lower ball socket 7 cover the whole spherical surface, so that the steel ball is ensured to have better roundness.
In order to reduce labor, improve efficiency and improve production safety, the present example employs a robot to turn the blank.
As shown in fig. 5, the structure of the clamp 3 mounted on the manipulator is schematically illustrated, the clamp 3 includes a first clamping arm 14 and a second clamping arm 15, a first support rod 8 is disposed on the first clamping arm 14, and a second support rod 9 is disposed on the second clamping arm 15. Both the first and second struts 8, 9 are rotatable along their own axes. The end parts of the first supporting rod 8 and the second supporting rod 9 are provided with clamping ends 10 for tightly abutting against the blank, and the structures of the two clamping ends 10 can be the same or different. The clamping end 10 may be disc-shaped to improve clamping stability.
The clamp 3 further comprises a driving mechanism 11, the driving mechanism 11 can be a servo motor or a pneumatic motor, and the driving mechanism 11 is mounted on the first clamping arm 14. Of course, the driving mechanism 11 may not be mounted on the first clamp arm 14 or the second clamp arm 15. The drive mechanism 11 is used to drive the first bar 8 to rotate, thereby rotating the blank when clamped.
The clamp 3 of this example is further provided with a link and a cylinder 13 to drive the first and second clamp arms 14 and 15 to open or clamp.
After the clamp 3 places the steel bar blank at the station, the first forging is carried out, in the forging process, the clamp 3 loosens the steel bar blank to allow the blank to be transversely deformed, and after the first forging is finished, the clamp 3 re-clamps the blank at the same position and rotates 90 degrees along a horizontal shaft (m-axis in figure 4). Followed by a second forging. The jaws 3 (or the robot) are removed during the second forging. Before the second forging operation is completed, the second jaw 3 (also the second manipulator) is ready to be brought into the vicinity of the new gripping point, which is the original two gripping points horizontally rotated by 90 ° around the centre of the billet. And immediately after the second forging, the second jaw 3 can be activated to grip the billet and rotate it by 90 ° (around the axis n in fig. 4), followed by the activation of the third forging. The main purpose of adopting another manipulator when the second forging is switched to the third forging is to reduce the time required for turning over the blank, thereby reducing the cooling amplitude of the steel ball and further ensuring the product quality.
The steel ball forging and pressing device is further provided with a laser scanning assembly (not shown in the figure), the laser scanning assembly is used for scanning the overall dimension of the forged steel ball, an instruction is fed back to the mechanical arm according to the scanning result, the mechanical arm overturns the steel ball to the angle expected by the instruction according to the instruction, and the steel ball is subjected to repair forging and pressing again, namely, the part protruding out of the spherical surface of the steel ball is corrected through forging and pressing, so that the correction purpose is achieved. The laser scanning and repairing process ensures the forming quality of the steel ball.
In the embodiment, the manipulator is adopted to turn the blank, three times of forging and pressing are carried out, workers are liberated to manufacture, the processing time is reduced, and the working efficiency is improved; meanwhile, safety accidents of staff are avoided; in addition, good working conditions are provided, so that equipment faults can be found and eliminated in time.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the content of the present invention and implement the invention, and not to limit the scope of the invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the scope of the present invention.
