[0028] Please refer to Figure 1-Figure 3 , this embodiment provides a spline side punching forming device, comprising:
[0029] The stamping assembly includes a pressing head 110, a work surface 120, an upper die base 130 and a lower die base 140. The upper die base 130 is fixed on the pressing head 110 and moves vertically with the pressing head 110. The lower die base 140 is fixed on the work surface 120.
[0030] The elastic support component is retractably arranged on the lower die base 140 and has an upper and lower material position and a punching position. The elastic support component is used to place the workpiece 200 to be processed and transfer the completed workpiece 200 to be processed from the punching position to the upper and lower material position;
[0031] An elastic material pressing assembly is installed on the upper die base 130, and is used to press the workpiece 200 to be processed onto the elastic material supporting assembly;
[0032] The stamping assembly also includes an inclined wedge mechanism and a forming mold. The forming mold includes a fixed die 310 and a movable punch 320. The fixed die 310 is fixed on the lower die base 140. The inclined wedge mechanism is used to convert the vertical movement of the upper die base 130 into the horizontal movement of the movable punch 320, so that the workpiece 200 to be processed is extruded and formed between the fixed die 310 and the movable punch 320.
[0033] The spline side punching forming device provided in this embodiment converts the vertical movement of the ram 110 into the horizontal movement of the movable punch 320, thereby extruding the required spline groove on the side of the workpiece 200 to be processed, thereby achieving precision processing of the non-through spline groove 210 and having high production efficiency.
[0034] In this embodiment, in the initial state, there is a distance between the upper die base 130 and the lower die base 140, so that the workpiece 200 to be processed can be placed on the elastic support assembly at the upper and lower material positions. When the workpiece 200 to be processed needs to be stamped, the pressure head 110 is driven downward and the upper die base 130 is driven downward. During the whole process, the lower die base 140 is fixed.
[0035] Please continue to refer to Figure 1 and Figure 2 The inclined wedge mechanism includes an inclined wedge 330 and a slider 340 . The top end of the inclined wedge 330 is connected to the upper die base 130 , and the bottom end has a matching inclined surface with the slider 340 . The slider 340 can be horizontally slidably arranged on the lower die base 140 , and the movable punch 320 is installed on the slider 340 . In the initial state, there is a gap between the beveled wedge 330 and the slider 340, that is, the two are not in contact. As the ram 110 moves downward, driving the upper die holder 130 downward, the beveled wedge 330 moves downward with the upper die holder 130. When the workpiece 200 to be processed reaches the stamping position, the workpiece 200 to be processed moves downward to just fit with the fixed die 310, and the inclined surface on the beveled wedge 330 just fits with the inclined surface on the slider 340. As the ram 110 continues to move downward, the vertical movement of the beveled wedge 330 is converted into a horizontal thrust on the slider 340, driving the slider 340 to move horizontally, and then driving the movable punch 320 thereon to move horizontally relative to the fixed die 310, thereby extruding the side of the workpiece 200 to be processed to form the required spline groove.
[0036] Furthermore, a fixed plate 350 is provided on the lower die base 140, and a slider 340 can be horizontally slidably provided on the fixed plate 350, and a first elastic element 360 is also provided between the slider 340 and the fixed plate 350. The first elastic element 360 includes but is not limited to a nitrogen spring, which mainly plays a resetting role. When the movable punch 320 moves horizontally relative to the fixed plate 350, the first elastic element 360 is compressed. When the workpiece 200 to be processed is processed, as the pressure head 110 moves upward to drive the upper die base 130 to open the mold, the slider 340 can be reset under the action of the first elastic element 360, so as to facilitate the processing of the next component to be processed.
[0037] Please continue to refer to Figure 1 and Figure 2 The elastic supporting assembly includes a supporting part 410 and a second elastic element 420. A movable groove is opened on the lower die base 140. The bottom end of the supporting part 410 is located in the movable groove and is elastically connected to the lower die base 140 through the second elastic element 420. The top end of the supporting part 410 is used to place the workpiece 200 to be processed.
[0038] In this embodiment, in the initial state, the second elastic element 420 is naturally extended, and it can also be understood that the second elastic element 420 only bears the weight of the supporting component 410 and the workpiece 200 to be processed thereon, and may be slightly compressed. The workpiece 200 to be processed is at the upper and lower material positions. When the ram 110 moves downward and drives the upper die seat 130 and the elastic pressing component to move downward, the elastic pressing component contacts the workpiece 200 to be processed. As the ram 110 continues to move downward, the elastic pressing component presses the workpiece 200 to be processed against the elastic supporting component, driving the supporting component 410 and the workpiece 200 to be processed thereon to move downward. At this time, the second elastic element 420 is gradually compressed until the workpiece 200 to be processed is pressed down to the stamping position. At this time, even if the ram 110 continues to move downward, the supporting component 410 and the workpiece 200 to be processed thereon will no longer move downward, and the second elastic element 420 maintains the current compressed state. The second elastic element 420 includes but is not limited to a nitrogen spring. When the workpiece 200 to be processed is processed, as the ram 110 moves upward to drive the upper mold base 130 to open the mold, the supporting component 410 can be reset to the upper and lower material positions under the action of the second elastic element 420 to facilitate the processing of the next component to be processed.
[0039] In this embodiment, the supporting component 410 includes a supporting base plate 411 and a plurality of supporting rods 412 arranged on the supporting base plate 411 . The workpiece 200 to be processed is placed on the supporting rods 412 . The supporting base plate 411 is elastically connected to the lower mold base 140 via a second elastic element 420 .
[0040] In this embodiment, the support bottom plate 411 is in a disc shape, and the support rods 412 are evenly distributed along the circumferential direction of the support bottom plate 411. It should be noted that the present invention does not impose any limitation on the number of the support rods 412.
[0041] Furthermore, when the support bottom plate 411 abuts against the bottom wall of the movable groove, the workpiece 200 to be processed is in the punching position. It should be noted that as the ram 110 continues to move downward, the support bottom plate 411 is driven downward, and the second elastic element 420 is gradually compressed. When the support bottom plate 411 moves downward to abut against the bottom wall of the movable groove, the support bottom plate 411 cannot move downward any further, and at this time, the second elastic element 420 is compressed to the limit.
[0042] In this embodiment, the elastic pressing assembly includes a press 510 and a third elastic element 520, and the two ends of the third elastic element 520 are respectively connected to the upper die base 130 and the press 510. In this embodiment, when the upper die base 130 follows the ram 110 to move downward, it drives the third elastic element 520 and the press 510 to move downward. When the press 510 moves downward until it abuts against the workpiece 200 to be processed, as the ram 110 continues to move downward, the workpiece 200 to be processed is pressed between the press 510 and the support component 410. At this time, it is mainly the second elastic element 420 that is compressed, and the third elastic element 520 is also compressed. When the support bottom plate 411 moves downward until it abuts against the bottom wall of the movable groove, the workpiece 200 to be processed reaches the stamping position, and the support bottom plate 411 can no longer move downward, and the second elastic element 420 is compressed to the limit. As the pressure head 110 continues to move downward, the third elastic element 520 continues to be compressed, but at this time the support component 410 and the workpiece 200 to be processed thereon continue to be pressed tightly and their positions are fixed. The vertical movement of the wedge 330 will be converted into a horizontal thrust on the slider 340, driving the slider 340 to move horizontally, and then driving the movable punch 320 thereon to move horizontally relative to the fixed die 310, thereby squeezing the side of the workpiece 200 to be processed to form the required spline groove.
[0043] In this embodiment, the third elastic element 520 includes but is not limited to a nitrogen spring. When the workpiece 200 is processed, as the punch 110 moves upward to drive the upper die seat 130 to move upward to open the mold, the presser 510 is reset under the action of the third elastic element 520.
[0044] Preferably, the spline side punch forming device further includes a guide assembly, which includes a plurality of guide rods 610 provided on the upper die base 130 and a plurality of guide holes 620 provided on the lower die base 140, wherein the guide rods 610 correspond to the guide holes 620 one by one and can be movably inserted into the corresponding guide holes 620. In this embodiment, the guide assembly is mainly used to position and guide the relative movement between the upper die base 130 and the lower die base 140 and the vertical movement of the related components, thereby improving the processing accuracy of the stamping forming.
[0045] Based on this, the processing method of the spline side punching forming device provided by the embodiment of the present invention is as follows:
[0046] S1. In the initial state, the second elastic element 420 is naturally stretched, and the support component 410 is at the upper and lower material positions. At this time, the workpiece 200 to be processed can be placed on the support component 410 by a robot;
[0047] S2, driving the ram 110 downward, and driving the upper die seat 130 and the elastic material pressing assembly downward until the presser 510 abuts against the workpiece 200 to be processed. As the ram 110 continues to descend, the workpiece 200 to be processed is pressed between the presser 510 and the supporting component 410. At this time, the second elastic element 420 is gradually compressed until the workpiece 200 to be processed is pressed down to the punching position, and the supporting component 410 abuts against the lower die seat 140 and stops descending. At this time, the workpiece 200 to be processed descends until it just fits with the fixed die 310, and the inclined surface on the inclined wedge 330 just fits with the inclined surface on the slider 340.
[0048] S3, as the pressure head 110 continues to move downward, the third elastic element 520 continues to be compressed, the inclined wedge 330 contacts and squeezes the slider 340, and the vertical movement of the inclined wedge 330 is converted into a horizontal thrust on the slider 340, driving the slider 340 to move horizontally, thereby driving the movable punch 320 thereon to move horizontally relative to the fixed die 310, thereby extruding the side of the workpiece 200 to be processed to form the required spline groove;
[0049] S4. After the processing is completed, as the ram 110 moves upward to drive the upper die holder 130 to open the mold, the supporting component 410 is reset under the action of the second elastic element 420, and the processed workpiece is moved up to the upper and lower material positions, and then the workpiece is taken away by the robot, and the remaining components are automatically reset.
[0050] In summary, the embodiment of the present invention provides a spline side punching forming device, which realizes the precision machining of the non-through spline groove 210 and has high production efficiency.
[0051] In addition, it should be recognized that although the present invention has been disclosed as a preferred embodiment, the above embodiment is not intended to limit the present invention. For any technician familiar with the art, without departing from the scope of the technical solution of the present invention, the technical content disclosed above can be used to make many possible changes and modifications to the technical solution of the present invention, or modified into equivalent embodiments of equivalent changes.
