Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
as shown in fig. 1, 5 to 8, and 17 to 20, the C-ring manufacturing apparatus provided in the present embodiment includes a punching mechanism, a supporting mechanism, a first supporting wheel 3, and a first pressing wheel 4. As shown in fig. 4 and 6, the punching mechanism and the supporting mechanism are located opposite to each other, and the punching mechanism can be moved closer to or farther from the supporting mechanism. The supporting mechanism is used for supporting the annular material plate 5, and the stamping mechanism is used for stamping the annular material plate 5 into a groove-shaped structure 50 with an annular groove bottom when approaching the supporting mechanism.
The first supporting wheel 3 is located at one side of the supporting mechanism, as shown in fig. 18, an annular first supporting groove 30 corresponding to the first pressing wheel 4 is provided on the first supporting wheel 3 along the circumferential direction of the first supporting wheel 3, and the height of the first supporting groove 30 along the axial direction of the first supporting wheel 3 is smaller than the height of the side wall of the groove-shaped structure 50. As shown in fig. 17 to 20, the first supporting wheel 3 or the first pressing wheel 4 can rotate, the first pressing wheel 4 is used for being attached to the inner side wall of the groove-shaped structure 50, and the first supporting wheel 3 is used for being attached to the outer side wall of the groove-shaped structure 50. The first extrusion wheel 4 can be brought close to the first support wheel 3 to cooperate with the first support groove 30 to extrude the groove-like structure 50 into a ring-like structure having an arc-shaped cross-section throughout.
In manufacturing the C-ring 51 shown in fig. 2 to 3 by using the C-ring manufacturing apparatus, as shown in fig. 4 to 6, the annular material plate 5 shown in fig. 4 may be placed on the support mechanism, the pressing mechanism may be brought close to the support mechanism, and the annular material plate 5 on the support mechanism may be pressed into the groove-like structure 50 having an annular groove bottom.
As shown in fig. 18, the first support wheel 3 is then attached to one side of the outer side wall of the annular groove-like structure 50, and the first pressing wheel 4 is attached to one side of the inner side wall of the groove-like structure 50. As shown in fig. 20, the first pressing wheel 4 is close to the supporting wheel, so that the first pressing wheel 4 presses the side wall of the groove-shaped structure 50 into the first supporting groove 30 on the first supporting wheel 3, and the first supporting wheel 3 or the first pressing wheel 4 can be driven to rotate. After the first supporting wheel 3 or the first pressing wheel 4 rotates, the side wall of the groove-shaped structure 50 can be driven to rotate when being pressed into the first pressing groove 90, so that the side wall of the groove-shaped structure 50 can be continuously pressed into the first pressing groove 90 along the circumferential direction of the groove-shaped structure 50. Since the height of the first support groove 30 in the axial direction of the first support wheel 3 is smaller than the height of the side wall of the channel structure 50, the side wall of the channel structure 50 can be extruded into an approximately C-shaped arc surface or a C-shaped arc surface after the side wall of the channel structure 50 is continuously extruded into the first extrusion groove 90. Finally, the groove-like structure 50 after the side walls are extruded can be modified to form an annular structure with a C-shaped axial cross section at each position of the groove-like structure 50, as shown in fig. 2 and 3, so that the groove-like structure 50 after the side walls are extruded can be made into a C-shaped ring 51.
The C-shaped ring manufacturing apparatus provided in this embodiment may stamp the annular material plate 5 into the groove-like structure 50 with the annular groove bottom by using the stamping mechanism and the supporting mechanism, and then may extrude the side wall of the groove-like structure 50 into an approximately C-shaped arc surface or a C-shaped arc surface by using the first supporting wheel 3 and the first extrusion wheel 4, so as to form the C-shaped ring 51. Compared with the prior art, the C-shaped ring manufacturing equipment provided by the embodiment does not need to weld the two ends of the strip-shaped metal material together, so that the welding defects of air holes, sand inclusion, incomplete penetration and the like in the manufactured C-shaped ring can be avoided, the thermal deformation caused by welding in the manufacturing process of the C-shaped ring 51 can be avoided, and the forming quality of the C-shaped ring 51 can be improved. In addition, the C-ring manufacturing apparatus provided in the present embodiment does not need to strictly control the welding process, so that the C-ring manufacturing apparatus provided in the present embodiment can also improve the production efficiency of the C-ring 51.
In addition, in the existing process of processing the metal C-shaped sealing ring, after two ends of the strip-shaped metal material are welded together, the surface precision of the welding position is poor, and therefore after the welding process is finished, the welding position needs to be polished. However, the grinding process further increases the manufacturing time of the metal C-shaped sealing ring, and reduces the production efficiency of the C-shaped sealing ring.
The C-shaped ring manufacturing equipment in the embodiment does not need to weld the two ends of the strip-shaped metal material together, so that the polishing process is saved deliberately, the production efficiency of the metal C-shaped sealing ring can be further improved, and the manufacturing cost of the metal C-shaped sealing ring is reduced.
It can be seen that, the C-shaped ring manufacturing equipment provided by the embodiment alleviates the technical problems that in the metal C-shaped sealing ring processing process existing in the prior art, when the two ends of the strip-shaped metal material are welded together, the welding process is easily influenced by many factors, the C-shaped sealing ring formed after welding easily has welding defects such as air holes, sand inclusion, incomplete penetration and the like, and in the welding process, the metal material is easily subjected to thermal deformation, so that the forming quality of the C-shaped sealing ring is low, and the production efficiency is not high.

The first support plate 20 is fixed in position, the first support plate 20 is provided with a first stamping groove 200, and the side edge of the opening of the first stamping groove 200 can support the part, located between the inner side edge and the outer side edge, of the annular material plate 5.

The annular material plate 5 is, for example, a steel plate, and further, the material of the annular material plate 5 may be a steel material having a low carbon content and good ductility. In order to press the annular material plate 5 into the groove-like structure 50 having the annular groove bottom, the diameter of the first press groove 200 is larger than the inner diameter of the annular material plate 5 and smaller than the outer diameter of the annular material plate 5.
In order to facilitate the machining of the C-shaped ring 51 with a desired size, the annular material plate 5 with a larger area may be used, so that the annular material plate 5 has a sufficient machining allowance. When processing a ring-shaped plate, the ring-shaped material plate 5 may be first placed at the opening of the first stamping groove 200 on the first support plate 20, and the side edge at the opening of the first stamping groove 200 supports the portion of the ring-shaped material plate 5 between the inner side edge and the outer side edge, and then the first stamping rod 10 is driven by an external force to move toward the first stamping groove 200, and after the first stamping rod 10 stamps the ring-shaped material plate 5 into the first stamping groove 200, the ring-shaped material plate 5 may be formed into the groove-shaped structure 50 shown in fig. 6 and 10, in which the notch has the skirt 500 and the groove bottom is ring-shaped. Further, the height of the side wall of the groove-like structure 50 with the skirt 500 at the notch and the annular groove bottom can be equal to the preset height of the side wall of the C-shaped ring 51 after being expanded.
Wherein, the power system for driving the first stamping rod 10 to approach or depart from the first supporting plate 20 can be a hydraulic system, the hydraulic system is connected with a hydraulic cylinder, and the hydraulic cylinder is connected with the first stamping rod 10.

The second support plate 21 is fixed in position, a stepped second stamping groove 210 is formed in the second support plate 21, the width of the portion, located on the plate surface of the first support plate 20, of the second stamping groove 210 is larger than that of the portion, located in the plate body of the first support plate 20, of the second stamping groove 210, and the second stamping groove 210 is used for accommodating the groove-shaped structure 50 with the annular groove bottom. The second stamping rod 11 is opposite to the second stamping groove 210, the second stamping rod 11 can be close to or far away from the second support plate 21, and the second stamping rod 11 is used for pushing the groove-shaped structure 50 with the annular groove-shaped structure in the second stamping groove 210 to move towards the groove bottom of the second stamping groove 210 when approaching the second support plate 21.
After stamping the annular material sheet 5 into the trough-like structure 50 having the notches with skirts 500 and the annular trough bottom as shown in fig. 6 and 10, in order to facilitate further processing of the trough-like structure 50, the skirts 500 at the openings of the trough-like structure 50 are cut out to form the trough-like structure 50 shown in fig. 16. At this time, the first support plate 20 on the base 6 and the support column 60 in the C-ring manufacturing apparatus may be replaced with the second support plate 21, and correspondingly, the first punching bar 10 may be replaced with the second punching bar 11, as shown in fig. 12 and 13.
As shown in fig. 13, since the second punched groove 210 is stepped and the width of the portion of the second punched groove 210 located on the plate surface of the second support plate 21 is larger than the width of the portion of the second punched groove 210 located in the plate body of the second support plate 21, the groove-like structure 50 having the notch with the skirt 500 can be placed in the second punched groove 210, the skirt 500 can be supported by the portion of the second punched groove 210 located on the plate surface of the second support plate 21, and the groove bottom and the side wall portion in the groove-like structure 50 are located in the portion of the second punched groove 210 located in the plate body of the second support plate 21.

Since the side wall of the groove-like structure 50 has a height equal to the height of the side wall of the C-shaped ring 51 after being unfolded, the C-shaped ring 51 with a predetermined size can be formed by bending the side wall of the groove-like structure 50.
As shown in fig. 1, 6 and 9, the supporting mechanism further comprises a first telescopic rod 22, a first stripping barrel 23 and a first stripping elastic member 24. As shown in fig. 7, the first support plate 20 is provided with a first punched hole, as shown in fig. 6, one end of the first telescopic rod 22 is sleeved with a first material releasing barrel 23, a barrel bottom of the first material releasing barrel 23 is located in the first punched hole, and the other end of the first telescopic rod 22 is fixed. The bottom of the first stripping barrel 23 and the side wall of the first punching hole close to the first punching rod 10 together form a first punching groove 200. A first stripping elastic part 24 is connected between the first stripping barrel 23 and the first telescopic rod 22.
In order for the first stamping bar 10 to stamp the annular material sheet 5 into the groove-like structure 50 with a specific sidewall height, the distance that the first stamping bar 10 moves in the first stamping groove 200 is controlled. As shown in fig. 8, the present embodiment preferably provides a ring-shaped abutment projection on the shaft of the first punching rod 10, which can abut on the first support plate 20, thereby limiting the moving distance of the first punching rod 10 in the first punching groove 200.
When the first stamping rod 10 is driven by an external force to stamp the annular material plate 5 into the first stamping groove 200, the end of the first stamping rod 10 extending into the first stamping groove 200 drives the first stripping barrel 23 to move towards the first telescopic rod 22, and the first stripping barrel 23 compresses the first stripping elastic member 24. When the first stamping rod 10 moves a certain distance in the first stamping groove 200 and stamps the annular material plate 5 into the groove-shaped structure 50 with the sidewall height being a certain value, the first stamping rod 10 is driven by an external force to move away from the first stamping groove 200, at this time, the first stamping rod 10 does not apply pressure to the first stripping barrel 23 any more, and the first stripping barrel 23 can push the groove-shaped structure 50 stamped into the annular groove bottom to move towards the first stamping rod 10 under the elastic recovery action of the first stripping elastic element 24.
It can be seen that the first telescopic rod 22, the first stripping barrel 23 and the first stripping elastic element 24 are used for driving the groove-shaped structure 50 with the annular groove bottom formed after stamping to move from the first stamping groove 200 to the first stamping rod 10 when the stamping of the first stamping rod 10 is finished and the first stamping rod is stamped out of the first stamping groove 200, so that the groove-shaped structure 50 with the annular groove bottom is prevented from being clamped in the first stamping groove 200 and being not easy to withdraw from the first stamping groove 200.
The first telescopic rod 22 is a telescopic rod and can be extended and retracted on the base 6, and the first material-releasing elastic member 24 can be a coil spring. As shown in fig. 1, the first stripping elastic element 24 is sleeved on the first telescopic rod 22, one end of the first stripping elastic element 24 abuts against the base 6, and the other end of the first stripping elastic element 24 abuts against the bottom of the first stripping barrel 23.
As shown in fig. 6 and 9, in order to prevent the first stripping barrel 23 from completely entering the first stamping groove 200, one end of the first stripping barrel 23 away from the first stamping rod 10 is provided with an extension part away from the axis of the first stripping barrel 23, and for the extension part, one side of the first supporting plate 20 away from the first stamping rod 10 is provided with an abutting groove, and the extension part on the first stripping barrel 23 can abut in the abutting groove to prevent the first stripping barrel 23 from completely entering the first stamping groove 200.
As shown in fig. 12-15, the supporting mechanism further comprises a second telescopic rod 25, a second stripping barrel 26 and a second stripping elastic member 27. A second stamping hole is formed in the second support plate 21, a second stripping barrel 26 is sleeved on one end of the second telescopic rod 25, the barrel bottom of the second stripping barrel 26 is located in the second stamping hole, and the other end of the second telescopic rod 25 is fixed in position. The bottom of the second stripping barrel 26 and the side wall of the second punching hole close to the second punching rod 11 jointly form a second punching groove 210. A second stripping elastic part 27 is connected between the second stripping barrel 26 and the second telescopic rod 25.
The function of the second telescopic rod 25 is the same as that of the first telescopic rod 22, the function of the second stripping barrel 26 is the same as that of the first stripping barrel 23, and the function of the second stripping elastic part 27 is the same as that of the first stripping elastic part 24, except that the first telescopic rod 22, the first stripping barrel 23 and the first stripping elastic part 24 are used in cooperation with the first punching rod 10 and the first support plate 20, and the second telescopic rod 25, the second stripping barrel 26 and the second stripping elastic part 27 are used in cooperation with the second punching rod 11 and the second support plate 21. And because the first stamping rod 10 and the second stamping rod 11 have different functions, the movement of the second stamping rod 11 in the second stamping groove 210 is longer than the movement stroke of the first stamping rod 10 in the first stamping groove 200, the length of the second telescopic rod 25 can be smaller than that of the first telescopic rod 22, and the height of the second stripping barrel 26 can be larger than that of the first stripping barrel 23.
Therefore, the second telescopic rod 25, the second stripping barrel 26 and the second stripping elastic member 27 are used for driving the groove-shaped structure 50 with the ring-shaped groove bottom, which is punched by the skirt 500, to move from the second stamping groove 210 to the second stamping rod 11 when the stamping of the second stamping rod 11 is finished and the second stamping rod is stamped out of the second stamping groove 210, so that the groove-shaped structure 50 is prevented from being clamped in the second stamping groove 210 and being difficult to withdraw from the second stamping groove 210.
The first telescopic rod 22 and the second telescopic rod 25 can be made of multiple sections of pipes which are sleeved together.

After the first stamping rod 10 finishes stamping and exits from the first stamping groove 200, the first stamping rod 10 can drive the stripper rod 12 to move away from the first support plate 20. When the material removing rod 12 moves to a certain distance, the material removing plate 13 can be moved together by the elastic member 14 connected between the material removing rod 12 and the material removing plate 13 to move away from the first support plate 20. After the stripper plate 13 moves to be separated from the supporting function of the first support plate 20, the stripper plate 13 can descend a certain distance under the action of its own weight. If the end of the first stamping rod 10 extending into the first stamping groove 200 carries the punched groove-like structure 50 out of the first stamping groove 200, the descending stripper plate 13 can exert a pushing action on the groove-like structure 50, so as to separate the groove-like structure 50 from the first stamping rod 10.
The stripper rod 12, the stripper plate 13 and the elastic member 14 can cooperate to separate the groove-like structure 50 clamped to the first stamping rod 10 from the first stamping rod 10.
