For the sake of understanding, the above mechanism is defined herein as a necking mechanism 4, a quincuncial shaping mechanism 2, a necking mechanism 4 and a polygonal shaping mechanism 3 in order along the feeding direction, and the above mechanism is not limited to the front-back order here, and an extending layout mode may be adopted.
In this embodiment, the feeding mechanism 1 includes two feeding rods 11 arranged in parallel and extending along a feeding direction, a plurality of sets of transmission turntables 12, and a feeding driving unit 13 in driving engagement with each set of transmission turntables 12, wherein each set of transmission turntables 12 is provided with two coaxially connected transmission turntables 12, and the axial directions of each set of transmission turntables 12 are parallel and sequentially arranged along the feeding direction. Specifically, the feeding driving unit 13 is a motor and a transmission belt, and is sequentially wound on a transmission wheel coaxially connected with each group of transmission turntables 12 through the transmission belt, so that the power output by the motor is transmitted to each group of transmission turntables 12 through the transmission belt to realize synchronous rotation. Secondly, the feeding rod 11 is eccentrically hinged with each group of transmission turntables 12 through a connecting rod, namely, one end of the connecting rod is hinged with the feeding rod 11, the other end of the connecting rod is eccentrically hinged with the transmission turntables 12, and the feeding rod 11 is driven to do periodic eccentric movement along with the rotation action of the transmission turntables 12. The feeding rods 11 are provided with a plurality of feeding grooves which are equidistantly arranged along the conveying direction and used for supporting the linkage shaft, the two ends of the linkage shaft are supported together by the feeding grooves which are aligned with the two feeding rods 11, and each group of transmission turntables 12 drive the feeding rods 11 to do periodic eccentric motion by means of the feeding driving unit 13, so that the feeding rods 11 can sequentially move progressively along the processing positions corresponding to the mechanisms.
In the present embodiment, each set of the necking mechanism 4 includes the necking die 41 and the third driving unit 42 that drives the necking die 41 to feed in the axial direction parallel to the linkage shaft, wherein the necking die 41 is provided with a necking hole 411 into which the end portion of the linkage shaft relatively extends, and the diameter width of the necking hole 411 is smaller than the diameter width of the linkage shaft. Therefore, when the linkage shaft moves to the processing station corresponding to the necking mechanism 4 along with the feeding mechanism 1, the end part of the linkage shaft is aligned with the necking hole 411 of the necking die 41, and then the third driving unit 42 drives the necking die 41 to feed in the axial direction of the linkage shaft, so that the end part of the linkage shaft gradually relatively stretches into the necking hole 411 for necking. After the diameter reduction is completed, the third driving unit 42 drives the reduction die 41 to return, and the end of the linkage shaft is separated from the exit reduction 411.
In order to facilitate the end of the linkage shaft extending into the shrinkage cavity 411 and the stability of the shrinkage processing, the outer end edge of the shrinkage cavity 411 in this embodiment is in a circular arc shape, and the shrinkage cavity 411 is provided with a second core rod 412 which can be relatively inserted into the hollow inner cavity of the linkage shaft, wherein a gap capable of accommodating the end of the linkage shaft is formed between the outer peripheral surface of the second core rod 412 and the inner wall of the shrinkage cavity 411, thereby avoiding the end of the linkage shaft from shifting or unnecessarily deforming during the shrinkage processing, and improving the stability of deformation.
Furthermore, two groups of necking mechanisms 4 are used for respectively carrying out necking processing on two end parts of the linkage shaft on two sides of the feeding mechanism 1, so that pretreatment processing on the end parts of the linkage shaft is realized, and the subsequent shaping processing of the plum blossom shaping mechanism 2 and the polygonal shaping mechanism 3 is facilitated.
In the present embodiment, the quincuncial shaping mechanism 2 includes a quincuncial die holder 21, a plurality of shaping blocks, and a first driving unit 22 for driving the quincuncial die holder 21 to feed in an axial direction parallel to the linkage shaft, wherein the quincuncial die holder 21 is provided with a die hole 211 into which one end of the linkage shaft relatively extends; a plurality of shaping blocks are annularly arranged on the inner peripheral surface of the die hole 211 (the shaping blocks protrude out of the inner peripheral surface of the die hole 211) and are used for radially pressing one end part of the linkage shaft extending into the die hole 211 to form a plum blossom shape; therefore, when the linkage shaft moves to the processing position corresponding to the plum blossom shaping mechanism 2 along with the feeding mechanism 1, the end part of the linkage shaft is aligned with the die hole 211 of the plum blossom die holder 21, the first driving unit 22 drives the necking die 41 to feed towards the axial direction of the linkage shaft, the end part of the linkage shaft gradually and relatively stretches into the die hole 211, and during stretching, the end part of the linkage shaft is radially pressed by the shaping blocks to form a plum blossom shape. In addition, after finishing the shaping process, the first driving unit 22 drives the quincuncial die holder 21 to reset, so that the end of the linkage shaft is separated from the exit die hole 211.
Further, in order to facilitate the end portion of the linkage shaft extending into the die hole 211 and the stability of the shaping process, the outer end edge of the shaping block in this embodiment is in a circular arc shape, and the die hole 211 is provided with a first core rod 212 which can be relatively inserted into the hollow inner cavity of the linkage shaft, wherein a gap capable of accommodating the end portion of the linkage shaft is formed between the outer peripheral surface of the first core rod 212 and the shaping block, thereby avoiding the end portion of the linkage shaft from shifting or unnecessarily deforming during the shaping process and improving the stability of deformation. And secondly, the end part of the linkage shaft is subjected to diameter reduction processing through a shrinkage cavity 411 mechanism in advance, so that the shaping processing of plum blossom shapes is facilitated, the deformation resistance is reduced, and the shaping is easier.
In this embodiment, the polygon shaping mechanism 3 includes a lower fixed die 31, an upper movable die 32, and a second driving unit 33 for driving the upper movable die 32 to open and close up and down relative to the lower fixed die 31, wherein polygon cavities are formed on opposite surfaces of the lower fixed die 31 and the upper movable die 32, and the two polygon cavities are offset from each other so that after the lower fixed die 31 and the upper movable die 32 are relatively closed, the two polygon cavities are closed to form a polygon extrusion cavity. Therefore, when the linkage shaft moves to the processing position corresponding to the polygon shaping mechanism 3 along with the feeding mechanism 1, the end of the linkage shaft is placed in the polygon die groove of the lower fixed die 31, and then the second driving unit 33 drives the upper movable die 32 to move downwards towards the lower fixed die 31 to form a polygon extrusion cavity, so that the end of the linkage shaft is pressed by the peripheral surface to form a polygon. In addition, after finishing the shaping processing, the second driving unit 33 drives the upper movable die 32 to move upwards and reset, so that the end part of the linkage shaft is separated from the polygonal extrusion cavity, and finally, the linkage shaft is supported and separated from the polygonal shaping mechanism 3 through the feeding mechanism 1.
In this embodiment, in order to avoid the problem that the universal driving shaft shifts when the plum blossom shaping mechanism 2 and the necking mechanism 4 perform axial radial and necking processing, a clamping mechanism 5 is further disposed between the plum blossom shaping mechanism 2 or the necking mechanism 4 and the feeding mechanism 1, that is, three groups of clamping mechanisms 5 in this embodiment are respectively correspondingly and adjacently disposed at the plum blossom shaping mechanism 2 and the two groups of necking mechanisms 4. Specifically, when the clamping mechanism 5 is used for carrying the plum blossom shaping mechanism 2 or the necking mechanism 4 to the processing station corresponding to the plum blossom shaping mechanism 2 or the necking mechanism 4, the clamping mechanism 5 is used for pre-clamping the linkage shaft, and then the plum blossom shaping mechanism 2 or the necking mechanism 4 is used for carrying out corresponding shaping processing.
Further, the clamping mechanism 5 of the embodiment includes a fixed clamping die 51, a movable clamping die 52, and a clamping driving unit 53 for driving the movable clamping die 52 to open and close relative to the fixed clamping die 51, wherein the tail end of the movable clamping die 52 is connected with the driving end of the clamping driving unit 53, and the movable clamping die 52 is hinged on the fixed clamping die 51 relatively to perform a turnover opening and closing action; the opposite surfaces of the fixed clamping die 51 and the movable clamping die 52 are respectively provided with clamping grooves, and after the fixed clamping die 51 and the movable clamping die 52 are closed, the two clamping grooves are closed to form a clamping cavity for clamping the linkage shaft. Therefore, the movable clamping die 52 is in an open state in advance, and when the linkage shaft of the feeding mechanism 1 moves to a processing station corresponding to the plum blossom shaping mechanism 2 or the necking mechanism 4 along with the feeding mechanism 1, the clamping driving unit 53 drives the movable clamping die 52 to turn over, close and clamp the linkage shaft so as to facilitate subsequent shaping processing; on the contrary, after finishing the shaping processing, the clamping driving unit 53 drives the movable clamping die 52 to turn over, and the linkage shaft is loosened, so that the feeding mechanism 1 bears the linkage shaft to move continuously.
In this embodiment, the opposite sides of the quincuncial shaping mechanism 2, the polygonal shaping mechanism 3 and the two groups of necking mechanisms 4 are respectively provided with a stop block which is in contact with the end of the linkage shaft, so that when one end of the linkage shaft is shaped, the stop block is used for limiting the stop block at the other end of the linkage shaft, and the function of positioning the axis of the linkage shaft is achieved.

The end of the linkage shaft is relatively separated from the withdrawing shrinkage cavity 411, the movable clamping die 52 of the first clamping mechanism 5 releases the linkage shaft, and then the feeding mechanism 1 carries the linkage shaft to move to the processing position corresponding to the plum blossom shaping mechanism 2.

The end of the linkage shaft is relatively separated from the withdrawing shrinkage cavity 411, the movable clamping die 52 of the third clamping mechanism 5 releases the linkage shaft, and then the feeding mechanism 1 carries the linkage shaft to move to the processing position corresponding to the polygon shaping mechanism 3.
Step S4: when the linkage shaft moves to a processing position corresponding to the polygon shaping mechanism 3, the right end part of the linkage shaft is placed in a polygon die groove of the lower fixed die 31; next, the second driving unit 33 of the polygon shaping mechanism 3 drives the upper moving die 32 to move downward, so that the upper moving die 32 is folded relative to the lower moving die to fold the two polygon cavities to form a polygon extrusion cavity, and the right end of the linkage shaft after the diameter reduction processing in step S3 is pressed by the polygon extrusion cavity to form a polygon. After the processing is completed, the second driving unit 33 of the polygon shaping mechanism 3 drives the upper movable die 32 to move upwards and reset, so that the upper movable die 32 is separated from the lower fixed die 31, and then the feeding mechanism 1 carries the linkage shaft to move and send out.
