The first embodiment is as follows:
as shown in fig. 1 to 3, the present invention provides a stepping spinning machine, which includes three first spinning units 1, the first spinning units 1 are sequentially arranged from left to right, a workpiece 9 is spun by a previous first spinning unit 1 and then moves to a next first spinning unit 1 for spinning, along a conveying direction of the workpiece 9, a processing precision of the first spinning unit 1 is gradually improved, for example, the leftmost first spinning unit 1 performs rough processing, the middle first spinning unit 1 performs fine processing, the rightmost first spinning unit 1 performs finish processing, the first spinning unit 1 includes a first spinning wheel 11 and a first mold core 12, and the first spinning wheel 11 is distributed on the periphery of the first mold core 12 for spinning the workpiece 9 on the first mold core 12.
The spinning processing of the workpiece 9 is divided into a plurality of stages, such as rough processing, fine processing, finish processing and the like, each stage is completed on one first spinning unit 1, the processing allowance of the spinning processing of the workpiece 9 is divided into a plurality of parts which can be distributed to different first spinning units 1, the requirements on the power, the pressure and the like of each first spinning unit 1 can be reduced, a driver with lower cost can be correspondingly used, such as a motor with lower power, as long as the spinning processing of the current stage is met, and therefore the first spinning units 1 with different configurations can be arranged aiming at different stages, and the cost is reduced; and the different stages can be performed simultaneously, although the time required for processing a single workpiece 9 does not change much, the total time for processing a plurality of workpieces 9 is shortened, for example, in the embodiment, the total time for processing three workpieces 9 is almost the same as the total time for processing one workpiece 9 in the normal operation process of the step spinning machine, so that the processing efficiency can be improved by times.
In this embodiment, the first spinning wheel 11 is connected to a first spinning driver for driving the first spinning wheel 11 to rotate, and the first mold core 12 is a passive rotation structure without power. It can be understood that, a first spinning driver for driving the first spinning wheel 11 to rotate may be connected to the first spinning wheel 11, and the first mold core 12 may be connected to a first mold core 12 driver for driving the first mold core 12 to rotate, for example, the first spinning driver may adopt a low-power motor to drive the first spinning wheel 11 to rotate, and after the first spinning wheel 11 contacts the workpiece 9, the first spinning wheel becomes a passive rotation that follows the rotation of the workpiece 9. Conversely, the first spinning wheel 11 can be designed to be a passive rotating structure without power, and the first mold core 12 is connected with a first mold core 12 driver for driving the first mold core 12 to rotate.
In this embodiment, a first spinning unit 1 includes two first spinning wheels 11, and two first spinning wheels 11 symmetric distribution are in the periphery of first mold core 12, and two first spinning wheels 11 atress are even, are favorable to guaranteeing spinning processing's stability. First spinning unit 1 includes first frame 100, and first spinning wheel 11 sliding connection is in first frame 100, and first spinning wheel 11 processes along axis of rotation reciprocating motion, can set up the mounting groove at first frame 100, and the lateral wall of mounting groove sets up guide rail 101, and first spinning wheel 11 is installed on support 13, and support 13 and guide rail 101 assembly sliding connection drive support 13 and first spinning wheel 11 reciprocating motion through hydraulic system or motor. The first mold core 12 and other parts are also installed on the first machine frame 100, so that the first spinning unit 1 can be modularized, and production, installation, debugging and maintenance are facilitated.
As shown in fig. 4, an upper platen 14 for pressing the workpiece 9 against the first mold core 12 is provided above the first spinning unit 1, the upper platen 14 rotates synchronously with the workpiece 9, a plurality of upper platens 14 are rotatably connected to one platen 15, and all the upper platens 14 press or loosen the workpiece 9 synchronously with the platen 15. Because the processing time of the first spinning units 1 to the workpiece 9 is similar or substantially equal, only one pressing plate 15 can be used to drive the upper pressing plates 14 to press the workpiece 9 or loosen the workpiece 9 at the same time, and compared with the upper pressing plates 14, the motion control mode of one pressing plate 15 is simple, for example, the pressing plate 15 is driven to move by the link mechanism 16 in this embodiment, or the pressing plate 15 can be driven to move by adopting a linear lifting mode or the like.
For automated processing, the step spinning machine includes a robot arm that moves the workpiece 9 from the previous first spinning unit 1 to the next first spinning unit 1. Of course, the workpiece 9 may be moved by a worker. A first placing table 17 on which a blank member is placed may be provided on the upstream side of the leftmost first spinning unit 1, and a second placing table 18 on which a finished member is placed may be provided on the downstream side of the rightmost first spinning unit 1.

Because the second spinning unit 2 carries out spinning processing on other workpieces 9 in the same time, the equivalent processing efficiency is doubled again on the basis of the embodiment, meanwhile, because two workpieces 9 are reversely abutted and fixed, an upper pressure plate 14, a pressure plate 15 and a corresponding driving system are omitted, the cost of the part can be converted into the improvement of the processing efficiency again, compared with the prior art, the input cost under the equivalent processing efficiency can be greatly reduced, and the processing efficiency under the equivalent input cost can be doubled by the same reason.
The driving mode of the second spinning wheel 21 and the second mold core 22 can be compared with that of the first spinning unit 1, the second spinning wheel 21 can be designed to be connected with a second spinning driver for driving the second spinning wheel 21 to rotate, and the second mold core 22 is in a passive rotation structure without power; or, the second spinning wheel 21 is connected with a second spinning driver for driving the second spinning wheel 21 to rotate, and the second mold core 22 is connected with a second mold core 22 driver for driving the second mold core 22 to rotate; or, the second spinning wheel 21 is a passive rotating structure without power, and the second mold core 22 is connected with a second mold core 22 driver for driving the second mold core 22 to rotate. Since the second core 22 is pressed against the first core 12 to fix the two workpieces 9 against each other, only one driver for the first core 12 and one driver for the second core 22 can be provided to reduce the cost.
In this embodiment, the second spinning unit 2 includes a second frame 200, the second spinning wheel 21 is slidably connected to the second frame 200, and the second spinning wheel 21 reciprocates along the rotation axis to perform machining, and the specific structure can refer to the first spinning unit 1.
In order to remove the workpiece 9 by demolding, the second spinning unit 2 needs to be separated from the first spinning unit 1, and for the convenience of control, the second spinning unit 2 is lifted up and down relative to the first spinning unit 1, for example, the second frame is lifted up and down relative to the first frame. Of course, if the conditions allow, the first spinning unit 1 may be lifted up and down with respect to the second spinning unit 2, for example, the second spinning unit 2 may be suspended. Besides the movement of the second frame or the first frame, the workpiece demoulding can also be moved by adopting a mode that the second mould core and/or the first mould core are lifted up and down and separated from each other.
Other contents not described in this embodiment may refer to embodiment one.
Other embodiments of the present invention than the preferred embodiments described above, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, should fall within the scope of the present invention defined in the claims.
