[0002] A plurality of flange plate parts for supporting are usually arranged on the pipe string of a hydraulic submersible pump system, and the flange plate part has an inner ring capable of sleeving the pipe string.

[0003] In the related art, a special spinning die is usually used to fix a plate blank with an inner ring on a spinning machine, and then the spinning machine is started to spin the outer edge of the plate blank to form a flange at 90° with the plate blank, so as to obtain the flange plate part.

[0004] However, in the related art, since the inner ring profiles of each plate blank are different, each spinning die can only be used to process one kind of flange plate part, the processing efficiency is low, and the processing difficulty and cost are high. SUMMARY

[0005] The plate processing device and the processing method provided by the embodiments of the present disclosure can process a plurality of flange plate parts with different inner ring profiles, improve the processing efficiency, and reduce the processing cost. The technical solutions are as follows.

[0006] The plate processing device provided by the embodiments of the present disclosure comprises a spinning machine and a die assembly. The spinning machine comprises a main shaft, a transition assembly, a spinning device, and a tail top shaft, and the main shaft and the transition assembly are coaxially connected. The spinning device and the tail top shaft are located on the side of the transition assembly away from the main shaft, and the tail top shaft is coaxial with the main shaft. The die assembly comprises a spinning die and a tail top plate, the spinning die is coaxially connected to the side of the transition assembly away from the main shaft, the tail top plate is located on the side of the spinning die away from the transition assembly, and the tail top plate is spaced apart from and coaxial with the spinning die. The side of the tail top plate away from the spinning die is coaxially connected to the tail top shaft.

[0007] In one implementation manner of the present disclosure, the transition assembly comprises an adapter sleeve and a transition flange, one end of the adapter sleeve is coaxially connected to one side of the transition flange, and the other end of the adapter sleeve is coaxially connected to the main shaft.

[0009] In yet another implementation of the present disclosure, the tail top plate includes a disc body and a sleeve. The sleeve is coaxially connected to a side of the disc body away from the spinning die. The tail top shaft is inserted into the sleeve at an end close to the tail top plate.

[0010] In yet another implementation of the present disclosure, the spinning die includes a die body, a positioning pin hole, and a positioning pin. The positioning pin hole is located on a side of the die body. One end of the positioning pin is accommodated in the positioning pin hole, and the other end of the positioning pin is located outside the positioning pin hole and away from the transition assembly.

[0011] In another implementation of the present disclosure, the number of spinning devices is at least two, and each of the spinning devices is arranged in a circumferential direction of the spinning die.

[0012] The plate processing method provided by the embodiments of the present disclosure is based on the plate processing device described above, and includes the following steps. A plate blank is provided. The spinning die is fixed on a side of the transition assembly away from the main shaft. The plate blank is placed on a side of the spinning die away from the transition assembly. The tail top shaft drives the tail top plate to move towards the spinning die to press the plate blank between the tail top plate and the spinning die, so that the outer edge of the plate blank protrudes radially beyond the outer edges of the tail top plate and the spinning die. The outer edge of the plate blank is spun by the spinning devices multiple times to form a flange, thereby obtaining a flanged plate.

[0013] In an implementation form of the present disclosure, before the outer edge of the plate blank is spun by the spinning device, the method comprises: simulating the spinning wheel trajectories of the spinning device, the number of the spinning wheel trajectories corresponding to the number of times the outer edge of the plate blank is spun by the spinning device, the spinning wheel trajectories comprising a first trajectory, a second trajectory, a third trajectory and a fourth trajectory. The first trajectory sequentially passes through a starting point, a first spinning point and an ending point, the starting point and the ending point being located outside the spinning die, and the first spinning point being located on the outer edge of the plate blank. The second trajectory sequentially passes through a preparation point, a second spinning point and an ending point, the preparation point and the ending point being located outside the spinning die, and the second spinning point being located on the outer edge of the plate blank. The third trajectory sequentially passes through a preparation point, a third spinning point and an ending point, the preparation point and the ending point being located outside the spinning die, and the third spinning point being located on the outer edge of the plate blank. The fourth trajectory sequentially passes through a preparation point, a fourth spinning point and an ending point, the preparation point and the ending point being located outside the spinning die, and the fourth spinning point being located on the outer edge of the plate blank. The first spinning point, the second spinning point, the third spinning point and the fourth spinning point are sequentially arranged along the axial direction of the spinning die.

[0014] In another implementation form of the present disclosure, when the outer edge of the plate blank is spun by the spinning device, the method comprises: gradually reducing the gap between the spinning device and the spinning die as the spinning sequence of the spinning device increases.

[0015] In yet another implementation form of the present disclosure, the gap between the spinning device and the spinning die gradually decreases as the spinning sequence of the spinning device increases, comprising: in the first spinning sequence, the gap between the spinning device and the outer surface of the spinning die gradually adjusts from 7mm to 6.5mm during the movement of the spinning device from contacting one end point of the plate blank to leaving one end point of the plate blank. In the second spinning sequence, the gap between the spinning device and the outer surface of the spinning die gradually adjusts from 6.55mm to 6.4mm during the movement of the spinning device from contacting one end point of the plate blank to leaving one end point of the plate blank. In the third spinning sequence, the gap between the spinning device and the outer surface of the spinning die gradually adjusts from 6.55mm to 5.95mm during the movement of the spinning device from contacting one end point of the plate blank to leaving one end point of the plate blank. In the fourth spinning sequence, the gap between the spinning device and the outer surface of the spinning die gradually adjusts from 6.55mm to 5.95mm during the movement of the spinning device from contacting one end point of the plate blank to leaving one end point of the plate blank.

[0016] The technical scheme provided by the embodiments of the present disclosure has the following beneficial effects:

[0017] In the process of making the flanged plate part from the plate part blank, since the transition assembly connected to the main shaft is coaxially connected to the spinning die, the spinning die can rotate coaxially with the main shaft. Since the tail top plate is located on the side of the spinning die away from the transition assembly, and the tail top shaft is coaxially connected to the side of the tail top plate away from the spinning die, the tail top shaft can drive the tail top plate to push towards the spinning die to press the plate part blank between the tail top plate and the spinning die, so even if the plate part blank to be processed has different inner ring profiles, it can be pressed between the spinning die and the tail top plate for spinning. Then the outer edge of the plate part blank is processed by the spinning device to obtain the flanged plate part.

[0018] That is, the plate part processing device can process various flanged plate parts with different inner ring profiles, improve processing efficiency, and reduce processing cost. BRIEF DESCRIPTION OF DRAWINGS

[0055] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0056] Figure 1 This is a schematic diagram of the structure of a plate processing device provided in an embodiment of this disclosure, as shown below. Figure 1 As shown, this embodiment of the present disclosure provides a sheet metal processing apparatus, including a spinning machine 10 and a die assembly 20. The spinning machine 10 includes a main shaft 110, a transition assembly 120, a spinning device 130, and a tail spindle 140. The main shaft 110 and the transition assembly 120 are coaxially connected. The spinning device 130 and the tail spindle 140 are both located on the side of the transition assembly 120 facing away from the main shaft 110, and the tail spindle 140 is coaxial with the main shaft 110. The die assembly 20 includes a spinning die 210 and a tail top plate 220. The spinning die 210 is coaxially connected to the side of the transition assembly 120 facing away from the main shaft 110. The tail top plate 220 is located on the side of the spinning die 210 facing away from the transition assembly 120. The tail top plate 220 is spaced apart from the spinning die 210 and coaxial with it. The side of the tail top plate 220 facing away from the spinning die 210 is coaxially connected to the tail spindle 140.

[0057] In the process of making the flanged plate 200 from the plate blank 100, since the transition assembly 120 connected to the main shaft 110 is coaxially connected to the spinning die 210, the spinning die 210 can rotate coaxially with the main shaft 110. Since the tail top plate 220 is located on the side of the spinning die 210 away from the transition assembly 120, and the tail top shaft 140 is coaxially connected to the side of the tail top plate 220 away from the spinning die 210, the tail top shaft 140 can drive the tail top plate 220 to push towards the spinning die 210 to press the plate blank 100 tightly between the tail top plate 220 and the spinning die 210, so even if the plate blank 100 to be processed has different inner ring 101 profiles, it can be pressed between the spinning die 210 and the tail top plate 220 for spinning. Then the outer edge of the plate blank 100 is processed by the spinning device 130 to obtain the flanged plate 200.

[0058] That is, the plate processing device can process various flanged plates 200 with different inner ring 101 profiles, improve processing efficiency, and reduce processing cost.

[0059] In the embodiment, the transition assembly 120 includes an adapter cylinder 121 and a transition flange 122, one end of the adapter cylinder 121 is coaxially connected to one side of the transition flange 122, and the other end of the adapter cylinder 121 is coaxially connected to the main shaft 110. The other side of the transition flange 122 is coaxially connected to the die assembly 20.

[0060] Continuing to refer to Figure 1 , for example, the transition flange 122 has a threaded hole on the side close to the adapter cylinder 121, and the adapter cylinder 121 has a through hole on the end surface close to the transition flange 122. The transition flange 122 and the adapter cylinder 121 are coaxially fixed and connected by bolt connection through the threaded hole. Because the adapter cylinder 121 is connected to the main shaft 110, when the main shaft 110 rotates, it can drive the adapter cylinder 121 to rotate coaxially, and the adapter cylinder 121 further drives the transition flange 122 to rotate coaxially.

[0061] Figure 2 is a structure schematic diagram of a transition flange 122 provided by the embodiment of the disclosure, as Figure 2 shown, in the embodiment, the transition flange 122 has a first mounting shoulder 1221 and a second mounting shoulder 1222 coaxial with the main shaft 110. Figure 3 is a structure schematic diagram of a spinning die 210 provided by the embodiment of the disclosure, as Figure 3 shown, the spinning die 210 has a third mounting shoulder 214 coaxial with the main shaft 110, and Figure 1The adapter sleeve 121 has a fourth mounting stop 1211 coaxial with the main shaft 110. The first mounting stop 1221 is located on the side of the transition flange 122 close to the adapter sleeve 121, the second mounting stop 1222 is located on the side of the transition flange 122 close to the spinning die 210, the third mounting stop 214 is located on the side of the spinning die 210 close to the transition flange 122, and the fourth mounting stop 1211 is located on the side of the adapter sleeve 121 close to the transition flange 122. The first mounting stop 1221 is in clearance fit with the fourth mounting stop 1211, and the second mounting stop 1222 is in clearance fit with the third mounting stop 214.

[0062] Exemplarily, because the first mounting stop 1221 on the side of the transition flange 122 close to the adapter sleeve 121 is in clearance fit with the fourth mounting stop 1211 on the side of the adapter sleeve 121 close to the transition flange 122, during the operation of assembling the transition flange 122 and the adapter sleeve 121, the first mounting stop 1221 is first aligned and fitted with the fourth mounting stop 1211, and then fixedly assembled, so as to ensure that the transition flange 122 and the adapter sleeve 121 can be coaxial when assembled together.

[0063] Continuing to refer to Figure 1 Exemplarily, because the second mounting stop 1222 on the side of the transition flange 122 close to the die assembly 20 is in the shape of a stepped surface with multiple coaxial bosses of different sizes, a suitable boss can be selected from the multiple bosses arranged in the shape of a stepped surface on the second mounting stop 1222, and the selected boss can be in clearance fit with the third mounting stop 214 on the side of the spinning die 210 close to the transition flange 122. Therefore, during the operation of assembling and connecting the transition flange 122 and the spinning die 210, the second mounting stop 1222 on the transition flange 122 can be first aligned and fitted with the third mounting stop 214 on the spinning die 210, and then the transition flange 122 and the spinning die 210 can be fixedly assembled, so as to ensure that the transition flange 122 and the adapter sleeve 121 can be coaxial when assembled together.

[0064] Continuing to refer to Figure 2 Exemplarily, the side of the transition flange 122 close to the spinning die 210 has multiple die mounting screw holes 1223, and the transition flange 122 and the spinning die 210 are coaxially fixedly connected through the connection of the screw holes and bolts, so that when the transition flange 122 rotates, the spinning die 210 coaxially connected with the transition flange 122 also rotates coaxially. In addition, because multiple die mounting screw holes 1223 are arranged on the radial surface of the transition flange 122, various spinning dies 210 of different diameters can be installed on the transition flange 122.

[0065] Figure 4is a structural schematic view of a tail top plate 220 provided by an embodiment of the present disclosure, as shown in Figure 4 The tail top plate 220 includes a disc body 221 and a shaft sleeve 222. The shaft sleeve 222 is coaxially connected to the side of the disc body 221 away from the spinning die 210. The tail top shaft 140 is inserted into the shaft sleeve 222 at the end close to the tail top plate 220.

[0066] Illustratively, because one side of the disc body 221 of the tail top plate 220 has the shaft sleeve 222, which can be inserted and fixed with the tail top shaft 140, the tail top plate 220 can rotate coaxially with the tail top shaft 140, and in the process of coaxial rotation, the tail top shaft 140 can resist the tail top plate 220 to reduce the deflection of the tail top plate 220 in the process of rotation.

[0067] Continuing to refer to Figure 4 Illustratively, the tail top plate 220 also has six reinforcing ribs 223 and six lightening holes 224. The six reinforcing ribs are uniformly welded on the side of the disc body 221 connected to the shaft sleeve 222 along the circumference of the disc body 221, and the length direction of the reinforcing ribs 223 is consistent with the radial direction of the disc body 221. Because of the arrangement of the reinforcing ribs 223, the rigidity of the tail top plate 220 can be enhanced, so that when the tail top plate 220 resists the plate blank 100 to perform spinning work, the planar deformation caused by spinning can be avoided. The six lightening holes 224 are all perforations and are uniformly arranged on the end face of the disc body 221 along the circumference of the disc body 221, and one lightening hole 224 is arranged between every adjacent two reinforcing ribs 223. Because of the arrangement of the lightening holes 224, the weight of the tail top plate 220 can be reduced, and the manufacturing cost of the tail top plate 220 can also be reduced.

[0068] Optionally, an inclined angle is formed on the outer edge of the side of the disc body 221 close to the spinning device 130. Because of the arrangement of the inclined angle on the outer edge of the side of the disc body 221 close to the spinning device 130, the spinning device 130 can reduce the contact with the disc body 221 when performing spinning work, and the safety in the process of spinning work is increased.

[0069] Figure 5 is a structural schematic view of a spinning die 210 provided by an embodiment of the present disclosure, as shown in Figure 5 In this embodiment, the spinning die 210 includes a die body 211, a positioning pin hole 212, and a positioning pin 213. The positioning pin hole 212 is located on the side of the die body 211. Again referring to Figure 3 The length direction of the positioning pin 213 is consistent with the depth direction of the positioning pin hole 212. One end of the positioning pin 213 is accommodated in the positioning pin hole 212, and the other end of the positioning pin 213 is located outside the positioning pin hole 212 and away from the transition assembly 120.

[0070] Continuing to refer to Figure 3For example, the end face of the spinning die 210 has nine positioning pin holes 212, each of which can be inserted with a positioning pin 213. Since one end of the positioning pin 213 is accommodated in the positioning pin hole 212, and the other end of the positioning pin 213 is located outside the end of the positioning pin hole 212 away from the transition assembly 120, the length J of the positioning pin 213 is greater than the depth K of the positioning pin hole 212, so that the inner circle 101 of the plate blank 100 can be abutted and fixed at the positioning pin hole with the positioning pin 213 inserted. The length J of the positioning pin 213 is 3mm more than the depth K of the positioning pin hole 212, and the thickness of the plate blank 100 is 4mm, so that the length of the positioning pin 213 more than the positioning pin hole 212 will not protrude from the inner circle 101 of the plate blank 100, thereby ensuring that the plate blank 100 is fixed without affecting the pressing operation of the tail top plate 220.

[0071] Continuing to refer to Figure 3 For example, the positioning pin hole 212 is provided as a stepped through hole, which facilitates the ejection of the positioning pin 213 accommodated in the positioning pin hole 212 from the side of the spinning die 210 away from the tail top plate 220 when the spinning die 210 is replaced.

[0072] Continuing to refer to Figure 3 For example, the spinning die 210 has flange mounting holes 215 on both sides, and the spinning die 210 and the transition flange 122 can be fixed coaxially by being screwed into the flange mounting holes 215 on the spinning die 210 and the die mounting screw holes 1223 on the transition flange 122 through bolt screw holes.

[0073] Again referring to Figure 5 It is worth noting that the nine positioning pin holes 212 are grouped into three groups, including three first positioning pin holes 2121, three second positioning pin holes 2122, and three third positioning pin holes 2123. The first positioning pin holes 2121 are close to the inner circle of the end face of the spinning die 210, the second positioning pin holes 2122 are close to the middle circle of the end face of the spinning die 210, and the third positioning pin holes 2123 are close to the outer circle of the end face of the spinning die 210. Each group of positioning pin holes 212 can be used for the cooperation and fixation of a plate blank 100. According to the contour shape of the inner circle 101 of the plate blank 100 to be pressed, an appropriate group of positioning pin holes 212 is selected, and the plate blank 100 is fixed on the side of the spinning die 210 away from the transition flange 122 by using the positioning pin 213 and the method of three-point positioning circle.

[0074] Figure 6 is a structural schematic diagram of a plate blank 100 provided by an embodiment of the present disclosure, as Figure 6 indicated, the inner circle 101 of the plate blank 100 to be fixed and pressed has a small contour. Again referring to Figure 5Three first positioning pin holes 2121 on the end face of the spinning die 210 close to the inside can be selected and corresponding positioning pins 213 are inserted, so that the positioning pins 213 can be used to fix the plate blank 100 on the side of the spinning die 210 away from the transition flange 122.

[0075] Figure 7 is another structural schematic diagram of a plate blank 100 provided by the embodiment of the present disclosure, as shown in the figure, the inner ring 101 of the plate blank 100 to be fixed and pressed is centered in size. Again referring to Figure 7 , three second positioning pin holes 2122 on the end face of the spinning die 210 close to the center position can be selected and corresponding positioning pins 213 are inserted, so that the positioning pins 213 can be used to fix the plate blank 100 on the side of the spinning die 210 away from the transition flange 122. Figure 5

[0076] Figure 8 is still another structural schematic diagram of a plate blank 100 provided by the embodiment of the present disclosure, as shown in the figure, the inner ring 101 of the plate blank 100 to be fixed and pressed is larger in size. Again referring to Figure 8 , three third positioning pin holes 2123 on the end face of the spinning die 210 close to the outside can be selected and corresponding positioning pins 213 are inserted, so that the positioning pins 213 can be used to fix the plate blank 100 on the side of the spinning die 210 away from the transition flange 122. Figure 5

[0077] In the embodiment, the number of spinning devices 130 is at least two, and each spinning device 130 is arranged along the circumference of the spinning die.

[0078] Again referring to Figure 1 , for example, the number of spinning devices 130 is two, and the two spinning devices 130 are arranged on the two sides of the plate blank 100 with the center point of the plate blank 100 as the symmetry center, and when the outer edge of the plate blank 100 is spun, the spinning wheel tracks of the two spinning devices 130 are also symmetrical with the center point of the plate blank 100. At the same time, the outer edge of the plate blank 100 is spun by using the two spinning devices 130, which can improve the spinning quantity and make the size control precision of the spun flange higher.

[0079] Figure 9 is a flow chart of a plate processing method provided by the embodiment of the present disclosure, as shown in the figure, the embodiment of the present disclosure provides a plate processing method based on the processing device, and the processing method comprises the following steps: Figure 9

[0080] Step S101: providing a plate blank 100.

[0081] ​​​Step S102: Assemble and fix the spinning die 210 on the side of the transition assembly 120 which is away from the main shaft 110.

[0082] Step S103: Place the plate blank 100 on the side of the spinning die 210 which is away from the transition assembly 120.

[0083] Step S104: Drive the tail top shaft 140 to push the tail top plate 220 towards the spinning die 210, so as to press the plate blank 100 between the tail top plate 220 and the spinning die 210, so that the outer edge of the plate blank 100 protrudes radially beyond the outer edge of the tail top plate 220 and the outer edge of the spinning die 210.

[0084] Step S105: Form a flange on the outer edge of the plate blank 100 by spinning the outer edge of the plate blank 100 multiple times by the spinning device 130, so as to obtain the flanged plate 200.

[0085] Figure 10 is a schematic diagram of a plate processing process provided by an embodiment of the present disclosure, in combination with Figure 10 , for example, a plate blank 100 is cut by a laser cutting method, and again referring to Figure 7 , the plate blank 100 is an annular flat plate with an inner ring 101, the diameter of the plate blank 100 is 793 mm, and the thickness of the plate blank 100 is 4 mm. Then, the main shaft 110, the adapter cylinder 121, the transition flange 122 and the spinning die 210 are coaxially assembled and fixed in sequence by means of bolt holes, so that when the main shaft 110 rotates, the adapter cylinder 121, the transition flange 122 and the spinning die 210 can be coaxially rotated in sequence. Place the plate blank 100 between the tail top plate 220 and the spinning die 210, and abut the tail top shaft 140 with the tail top plate 220, push the tail top plate 220 towards the spinning die 210, so as to press the plate blank 100 between the tail top plate 220 and the spinning die 210, and make the outer edge of the plate blank 100 protrude radially beyond the outer edge of the tail top plate 220 and the outer edge of the spinning die 210. Then start the spinning operation on the outer edge of the plate blank 100, and during the spinning process, the spinning device 130 trajectory is controlled step by step to gradually increase the spinning flange angle of the plate blank 100 to form a flange, and finally obtain the flanged plate 200.
