Description

Technical Field

[0001] The present invention relates to the technical field of rotary cutting forming devices, and particularly to a rotary cutting forming device for producing cylindrical parts. Background Art

[0002] Cylindrical parts with a bottom flange are applied in the aviation field, such as the flame tube of a turbojet or turbofan engine. The cylindrical part includes a bottom plate and an inner cylinder. In the prior art, "Research on Rotary Cutting Forming Process of Cylindrical Parts with Bottom Flange" in the journal "Aeronautical Manufacturing Technology" proposed to process the inner cylinder by the rotary cutting process of a rotary cutting forming device. The rotary cutting forming device includes a backing plate, a core mold, and a rotary wheel. During processing, the core mold first presses the blank plate against the backing plate. After the backing plate, the blank plate, and the core mold rotate, the inclined rotary wheel first cuts the edge of the blank plate along the radial direction of the blank plate. The edge of the blank plate bifurcates to form a base plate and a flared flange. Then the rotary wheel moves upward and spins the flared flange, causing the flared flange to deform and form an inner cylinder that fits on the outside of the core mold. The cylindrical structure formed by the above process is an integrally formed structure, and the stability of the structure is better.

[0003] However, the existing rotary cutting forming device does not have a function of reminding to replace the rotary wheel after the rotary wheel is severely worn. When processing with a severely worn rotary wheel, on the one hand, the outside of the rotary wheel will become not "sharp" enough, that is, the fillet of the rotary wheel will become larger, and the fillet part will play a rolling role on the blank plate, and the material flow of the blank plate will be very different from the rotary cutting shunting, thus affecting the rotary cutting. On the other hand, the outer diameter of the worn rotary wheel will decrease, so that after the rotary wheel moves a preset distance along the radial direction of the blank plate, the cutting depth of the rotary wheel cannot reach the target requirement, that is, the horizontal distance between the rotary wheel and the core shaft is too large. At this time, after the rotary wheel moves upward and spins the flared flange, the formed inner cylinder cannot fit with the core mold, and finally the product is unqualified. Summary of the Invention

[0004] In order to solve the problem that the existing rotary cutting forming device does not have a function of reminding to replace the rotary wheel, the present invention provides a rotary cutting forming device for producing cylindrical parts, which can remind to replace the rotary wheel.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A spinning forming device for producing cylindrical parts, comprising a base, a rotating table rotatably connected to the upper side of the base, a clamping mechanism for fixing a blank plate on the rotating table, a rotating mechanism for driving the rotation of the rotating table, a spinning wheel arranged on one side of the rotating table, and a first driving mechanism for driving the spinning wheel to move radially along the blank plate to perform spinning on the blank plate. The spinning forming device for producing cylindrical parts further comprises a power supply and an independently powered alarm. The spinning wheel includes a pre-working position. When the spinning forming device for producing cylindrical parts is working, the blank plate, the power supply, and the spinning wheel are electrically connected in sequence to form a circuit, and an insulating layer is arranged between the spinning wheel and the base; when the first driving mechanism drives the spinning wheel to move to the pre-working position and the spinning wheel abuts against the blank plate, the circuit is in a closed state; when the first driving mechanism drives the spinning wheel to move to the pre-working position and there is a gap between the spinning wheel and the blank plate, the circuit is disconnected at the gap; a current detection device is arranged on the circuit, which can make the alarm emit an alarm when the circuit is disconnected.

[0007] With the above settings, when the present application is working, the first driving mechanism first drives the spinning wheel to move to the pre-working position, and the current detection device is used to judge whether the spinning wheel abuts against the blank plate. If the spinning wheel does not abut against the blank plate, it indicates that the outer extension of the spinning wheel is severely worn, the circuit will be in an open state, no current passes through the current detection device, the current detection device sends a signal to the alarm, and the alarm emits an alarm to remind the operator to replace the spinning wheel, preventing the severely worn spinning wheel from continuing to process cylindrical parts and generating unqualified cylindrical parts, thereby reducing losses.

[0008] Further, when the circuit is closed, the current detection device sends a signal to the first driving mechanism, and the first driving mechanism drives the spinning wheel to move radially along the blank plate and perform spinning on the blank plate.

[0009] With the above settings, when the current detection device determines that the wear of the spinning wheel is within the specified range, the current detection device sends a signal to the first driving mechanism, and the first driving mechanism continues to drive the spinning wheel to move radially along the blank plate to perform spinning on the blank plate.

[0010] Further, when the first driving mechanism drives the spinning wheel to move to the pre-working position and the spinning wheel abuts against the blank plate, the depth d of the spinning wheel cutting the blank plate satisfies d≥0 and d≤1 mm.

[0011] Further, a top plate is arranged above the base, the top plate is fixedly connected to the base through a connecting plate, the clamping mechanism includes a first oil cylinder arranged on the lower side of the top plate, the first oil cylinder includes a first cylinder body and a first piston rod, the first cylinder body is fixedly connected to the top plate, and the first piston rod extends downward and is rotatably connected to an extrusion column for pressing the blank plate against the rotating table.

[0012] With the above settings, when the pressing column presses the blank plate against the rotating table, the blank plate is not likely to slide on the rotating table when being rotary swaged by the swaging wheel.

[0013] Furthermore, a lifting table is arranged on the upper side of the base, the first driving mechanism is arranged on the lifting table, and the base is provided with a lifting mechanism for driving the lifting table to move upward so as to move the swaging wheel upward.

[0014] Furthermore, a sliding groove is arranged on the upper side of the lifting table. The first driving mechanism includes a first sliding seat slidably connected in the sliding groove, a second oil cylinder for driving the first sliding seat to move along the sliding groove, a support plate detachably connected to the upper side of the first sliding seat, a second sliding seat slidably connected to the upper side of the support plate, and a third oil cylinder for driving the second sliding seat to move along the support plate. The swaging wheel is rotatably connected to one side of the second sliding seat close to the rotating table, and an insulating layer is arranged between the support plate and the first sliding seat.

[0015] Furthermore, a pressing cylinder for pressing the blank plate downward to prevent the blank plate from moving laterally on the rotating table is arranged below the top plate. The outer diameter of the pressing cylinder is smaller than the diameter of the blank plate. The pressing cylinder and the pressing column are coaxial, and the pressing column is arranged in the pressing cylinder. A plurality of fourth oil cylinders for driving the pressing cylinder to move up and down are arranged on the lower side of the top plate. The fourth oil cylinders are arranged in sequence around the axis of the first oil cylinder. The fourth oil cylinder includes a second cylinder body and a second piston rod. The second cylinder body is fixedly connected to the top plate, the second piston rod extends downward and is fixedly connected with a mounting plate. The mounting plate is annular. The first piston rod passes through the mounting plate, and the pressing cylinder is rotatably connected to the lower side of the mounting plate. The first sliding seat is provided with a measuring device for measuring the moving distance of the second sliding seat in real time to control the upward movement of the pressing cylinder.

[0016] With the above settings, the advancing speed of the swaging wheel when swaging the blank plate can be increased, thereby improving the production efficiency of the tubular parts in this application.

[0017] Furthermore, a positioning protrusion is fixedly connected to the upper side of the support plate, and a positioning surface is arranged at one end of the sliding groove close to the rotating table. When the side of the second sliding seat away from the rotating table abuts against the positioning protrusion and the first sliding seat abuts against the positioning surface, the swaging wheel is in the pre-working position.

[0018] With the above settings, it is easier to control the movement of the swaging wheel by the first driving mechanism.

[0019] Furthermore, the power supply includes a coil fixedly connected to the inner wall of the pressing cylinder and a magnet fixedly connected to the side surface of the first piston rod. The coil, the pressing cylinder, the mounting plate, the current detection device, and the swaging wheel are electrically connected in sequence.

[0020] When the pressing cylinder abuts against the blank plate and the swaging wheel abuts against the blank plate, a closed circuit is formed among the coil, the pressing cylinder, the mounting plate, the current detection device, the swaging wheel, and the blank plate.

[0021] When the extrusion cylinder abuts against the blank plate and there is a gap between the spinning wheel and the blank plate, a circuit that is disconnected at the gap is formed among the coil, the extrusion cylinder, the mounting plate, the current detection device, the spinning wheel, and the blank plate.

[0022] With the above arrangement, when the present application is working, it can generate electricity automatically and be used for determining the wear degree of the spinning wheel.

[0023] Furthermore, the rotating mechanism includes a driven wheel fixedly connected to the rotating table, a motor disposed on the lower side of the base, and a driving wheel connected to the motor. The driving wheel is drivingly connected to the driven wheel through a belt.

[0024] With the above arrangement, the rotating table has a large driving force, and the motor drives the rotating table to rotate through the driving wheel, the belt, and the driven wheel. Description of the Drawings

[0032] Next, through embodiments and in combination with the drawings, the technical solutions of the present invention will be further specifically described.

[0033] See Figures 1 to 7, A spinning forming device for producing cylindrical parts, comprising a base 11, a rotating table 12 rotatably connected to the upper side of the base 11, a clamping mechanism for fixing a blank plate 21 on the rotating table 12, a rotating mechanism 14 for driving the rotation of the rotating table 12, a spinning wheel 15 arranged on one side of the rotating table 12, and a first driving mechanism for driving the spinning wheel 15 to move radially along the blank plate 21 to perform spinning on the blank plate 21. The spinning forming device for producing cylindrical parts further includes a power source and an independently powered alarm 18. The spinning wheel 15 includes a pre-working position. When the spinning forming device for producing cylindrical parts is working, the blank plate 21, the power source, and the spinning wheel 15 are electrically connected in sequence to form a circuit, and an insulating layer 111 is provided between the spinning wheel 15 and the base 11; when the first driving mechanism drives the spinning wheel 15 to move to the pre-working position and the spinning wheel 15 abuts against the blank plate 21, the circuit is in a closed state; when the first driving mechanism drives the spinning wheel 15 to move to the pre-working position and there is a gap between the spinning wheel 15 and the blank plate 21, the circuit is disconnected at the gap; a current detection device 19 is provided on the circuit, which can make the alarm 18 emit an alarm when the circuit is disconnected.

[0034] With the above arrangement, when the present application is working, the first driving mechanism first drives the spinning wheel 15 to move to the pre-working position, and the current detection device 19 is used to judge whether the spinning wheel 15 abuts against the blank plate 21. If the spinning wheel 15 does not abut against the blank plate 21, it indicates that the outer extension of the spinning wheel 15 is severely worn, the circuit will be in an open state, no current will pass through the current detection device 19, the current detection device 19 sends a signal to the alarm 18, and the alarm 18 emits an alarm to remind the operator to replace the spinning wheel 15, preventing the severely worn spinning wheel 15 from continuing to process cylindrical parts and generating unqualified cylindrical parts, thus reducing losses.

[0035] Specifically, when producing a cylindrical part, a circular blank plate 21 is placed on the upper side of the rotating table 12, and the clamping mechanism fixes the blank plate 21 on the rotating table 12. The rotating mechanism 14 drives the rotating table 12 and the blank plate 21 to rotate. At this time, there is an electrical connection between the power source and the blank plate 21, and there is an electrical connection between the power source and the rotating wheel 15. Under the action of the insulating layer 111, the blank plate 21 will not conduct electricity through the base 11 and form a closed loop with the rotating wheel 15. The first driving mechanism drives the rotating wheel 15 to move towards the blank plate 21 along the radial direction of the blank plate 21. If the rotating wheel 15 is not worn or the wear is within the specified range, when the rotating wheel 15 moves to the pre-working position, the rotating wheel 15 cuts into or just abuts against the edge of the blank plate 21. Both the blank plate 21 and the rotating wheel 15 are made of metal conductive materials, and the circuit is closed to form a loop, and there is current passing through the current detection device 19. If the outer extension of the rotating wheel 15 is severely worn, when the rotating wheel 15 moves to the pre-working position, the rotating wheel 15 will not be able to contact the blank plate 21. At this time, there will be a gap between the blank plate 21 and the rotating wheel 15, and the circuit is disconnected and cannot form a loop. At this time, there is no current passing through the current detection device 19, and the current detection device 19 sends a signal to the alarm 18, and the alarm 18 issues an alarm to remind the operator to replace the rotating wheel 15.

[0036] As an implementation method, when the circuit is closed, the current detection device 19 sends a signal to the first driving mechanism, and the first driving mechanism drives the rotating wheel 15 to move along the radial direction of the blank plate 21 and cut and rotate the blank plate 21.

[0037] Through the above settings, after the current detection device 19 determines that the wear of the rotating wheel 15 is within the specified range, the current detection device 19 sends a signal to the first driving mechanism, and the first driving mechanism continues to drive the rotating wheel 15 to move along the radial direction of the blank plate 21 to cut and rotate the blank plate 21.

[0038] As an implementation method, when the first driving mechanism drives the rotating wheel 15 to move to the pre-working position and the rotating wheel 15 abuts against the blank plate 21, the depth d of the rotating wheel 15 cutting and rotating the blank plate 21 is greater than or equal to zero and less than or equal to one millimeter.

[0039] When the unworn rotating wheel 15 is in the pre-working position, the rotating wheel 15 cuts the edge of the blank plate 21, and the cutting depth is one millimeter. Refer to Figure 4 , the greater the wear degree of the rotating wheel 15, the smaller the depth of the rotating wheel 15 cutting and rotating the blank plate 21 when the rotating wheel 15 moves to the pre-working position. When the wear degree of the rotating wheel 15 reaches the critical value of the specified range, the rotating wheel 15 just abuts against the edge of the blank plate 21 when moving to the pre-working position and does not cut and rotate the blank plate 21.

[0040] As an implementation, a top plate 112 is provided above the base 11. The top plate 112 is fixedly connected to the base 11 through a connecting plate 113. The clamping mechanism includes a first oil cylinder disposed on the lower side of the top plate 112. The first oil cylinder includes a first cylinder block 132 and a first piston rod 133. The first cylinder block 132 is fixedly connected to the top plate 112. The first piston rod 133 extends downward and is rotatably connected to an extrusion column 134 for pressing the blank plate 21 against the rotating table 12.

[0041] With the above arrangement, when the extrusion column 134 presses the blank plate 21 against the rotating table 12, the blank plate 21 is not likely to slide on the rotating table 12 when being spun and cut by the spinning wheel 15.

[0042] Specifically, when the blank plate 21 is being spun and cut by the spinning wheel 15, the spinning wheel 15 exerts a radial force on the blank plate 21. If the pressure between the blank plate 21 and the rotating table 12 is not large enough, the blank plate 21 is likely to shift when being spun and cut by the spinning wheel 15. During the operation of this application, when the first oil cylinder extends, the first piston rod 133 moves downward and drives the extrusion column 134 to move downward. The extrusion column 134 presses the blank plate 21 against the rotating table 12. The first oil cylinder has a large driving force, so that the pressure between the blank plate 21 and the rotating table 12 is large enough.

[0043] As an implementation, a lifting platform 114 is provided on the upper side of the base 11. The first driving mechanism is disposed on the lifting platform 114. The base 11 is provided with a lifting mechanism 115 for driving the lifting platform 114 to move upward so that the spinning wheel 15 moves upward.

[0044] After the spinning wheel 15 performs spinning and cutting along the radial direction of the blank plate 21 under the action of the first driving mechanism, the edge of the blank plate 21 bifurcates to form a base plate 22 and a flared flange 23. Refer to Figure 5 , as the first driving mechanism advances the spinning wheel 15, the height of the flared flange 23 gradually increases. When the spinning wheel 15 approaches the extrusion column 134, the first driving mechanism stops. The lifting mechanism 115 drives the lifting platform 114 to move upward. The lifting platform 114 drives the spinning wheel 15 to move upward through the first driving mechanism. The spinning wheel 15 spins and presses the flared flange 23 and deforms the flared flange 23 to form an inner cylinder that fits on the outside of the extrusion column 134. Refer to Figure 7 . Among them, the lifting mechanism can be set as an oil cylinder.

[0045] As an implementation, a chute 1141 is provided on the upper side of the lifting platform 114. The first driving mechanism includes a first sliding seat 161 slidably connected in the chute 1141, a second oil cylinder 162 for driving the first sliding seat 161 to move along the chute 1141, a support plate 163 detachably connected to the upper side of the first sliding seat 161, a second sliding seat 164 slidably connected to the upper side of the support plate 163, and a third oil cylinder 165 for driving the second sliding seat 164 to move along the support plate 163. The rotating wheel 15 is rotatably connected to the side of the second sliding seat 164 close to the rotating table 12, and the insulating layer 111 is provided between the support plate 163 and the first sliding seat 161.

[0046] Among them, the second oil cylinder 162 is provided on the base 11, and the third oil cylinder 165 is provided on the first sliding seat 161.

[0047] As an implementation, a pressing cylinder 116 is provided below the top plate 112 for pressing the blank plate 21 downward to prevent the blank plate 21 from moving laterally on the rotating table 12. The outer diameter of the pressing cylinder 116 is smaller than the diameter of the blank plate 21. The pressing cylinder 116 and the pressing column 134 are coaxial, and the pressing column 134 is provided in the pressing cylinder 116. A plurality of fourth oil cylinders 117 for driving the pressing cylinder 116 to move up and down are provided on the lower side of the top plate 112. The fourth oil cylinders 117 are arranged in sequence around the axis of the first oil cylinder. The fourth oil cylinder 117 includes a second cylinder body 1171 and a second piston rod 1172. The second cylinder body 1171 is fixedly connected to the top plate 112, and the second piston rod 1172 extends downward and is fixedly connected to a mounting plate 1173. The mounting plate 1173 is annular. The first piston rod 133 passes through the mounting plate 1173, and the pressing cylinder 116 is rotatably connected to the lower side of the mounting plate 1173. The first sliding seat 161 is provided with a measuring device (not shown in the figure) for measuring the moving distance of the second sliding seat 164 in real time to control the upward movement of the pressing cylinder 116.

[0048] Through the above settings, the advancing speed of the rotating wheel 15 during the cutting and spinning of the blank plate 21 can be increased, thereby improving the production efficiency of the tubular parts in this application.

[0049] Specifically, when the rotating wheel 15 cuts and spins the blank plate 21, the radial force of the rotating wheel 15 on the blank plate 21 increases with the increase of the advancing speed. In reality, in order to prevent the blank plate 21 from slipping on the rotating table 12 during the cutting and spinning of the rotating wheel 15, the advancing speed of the rotating wheel 15 is relatively small. When this application is in use, after the blank plate 21 is placed on the rotating table 12, in addition to the pressing column 134 pressing the blank plate 21 against the rotating table 12, the fourth oil cylinder 117 drives the pressing cylinder 116 to move downward, and the pressing cylinder 116 also applies a downward force to the blank plate 21, thereby increasing the pressure between the blank plate 21 and the rotating table 12, and further increasing the stability of the blank plate 21 on the rotating table 12. See Figure 3。When the spinning wheel 15 is performing spinning, the rotating table 12, the blank plate 21, the extrusion column 134, and the extrusion cylinder 116 rotate synchronously. The third oil cylinder 165 pushes the second sliding seat 164, and the second sliding seat 164 moves towards the rotating table 12. The second sliding seat 164 drives the spinning wheel 15 to move, and the spinning wheel 15 spins the edge of the blank plate 21 to bifurcate the edge of the blank plate 21. Since the stability of the blank plate 21 is increased under the action of the extrusion cylinder 116, the pushing speed of the third oil cylinder 165 can be relatively fast, that is, the speed at which the spinning wheel 15 moves along the radial direction of the blank plate 21 is faster, thereby improving the spinning efficiency. During this process, the measuring device measures the moving distance of the second sliding seat 164 in real time. The measuring device can be set as a travel switch or an infrared rangefinder, and can be adjusted according to the actual situation. When the moving distance of the second sliding seat 164 reaches the preset value, the measuring device sends a signal to the third oil cylinder 165, and the pushing speed of the third oil cylinder 165 decreases. Then the measuring device sends a signal to the fourth oil cylinder 117, and the fourth oil cylinder 117 drives the extrusion cylinder 116 to move upward to prevent the spinning wheel 15 from interfering with the extrusion cylinder 116 during the pushing process. Then the third oil cylinder 165 continues to push the second sliding seat 164 until the trumpet-shaped flanging 23 is processed.

[0050] As an implementation manner, a positioning protrusion 1631 is fixedly connected to the upper side of the support plate 163, and a positioning surface 1142 is provided at one end of the sliding groove 1141 close to the rotating table 12. When the side of the second sliding seat 164 away from the rotating table 12 abuts against the positioning protrusion 1631 and the first sliding seat 161 abuts against the positioning surface 1142, the spinning wheel 15 is in the pre-working position.

[0051] Through the above settings, it is easier to control the movement of the spinning wheel 15 driven by the first driving mechanism.

[0052] Specifically, when the present application works, first, the second oil cylinder 162 drives the first sliding seat 161 to move along the sliding groove 1141 towards the rotating table 12. The first sliding seat 161 drives the second sliding seat 164 and the spinning wheel 15 to approach the extrusion column 134. When the first sliding seat 161 moves to the positioning surface 1142, at this time, the spinning wheel 15 is in the pre-working position. Refer to Figure 3 。If the spinning wheel 15 abuts against the blank plate 21 and there is current passing through the current detection device 19, the current detection device 19 sends a signal to the third oil cylinder 165, and the third oil cylinder 165 drives the second sliding seat 164 to move along the radial direction of the blank plate 21 towards the blank plate 21, so that the spinning wheel 15 continues to push to perform spinning on the blank plate 21.

[0053] As an implementation method, the power supply includes a coil 171 fixedly connected to the inner wall of the extrusion cylinder 116 and a magnet 172 fixedly connected to the side of the first piston rod 133. The coil 171, the extrusion cylinder 116, the mounting plate 1173, the current detection device 19, and the rotating wheel 15 are electrically connected in sequence.

[0054] When the extrusion cylinder 116 abuts against the blank plate 21 and the rotating wheel 15 abuts against the blank plate 21 , a closed circuit is formed among the coil 171 , the extrusion cylinder 116 , the mounting plate 1173 , the current detection device 19 , the rotating wheel 15 , and the blank plate 21 .

[0055] When the extrusion cylinder 116 and the blank plate 21 are in contact and there is a gap between the rotating wheel 15 and the blank plate 21 , a circuit that is disconnected at the gap is formed between the coil 171 , the extrusion cylinder 116 , the mounting plate 1173 , the current detection device 19 , the rotating wheel 15 , and the blank plate 21 .

[0056] Through the above arrangement, the present application can automatically generate electricity when working and be used to determine the degree of wear of the rotating wheel 15.

[0057] Specifically, when the extrusion column 134, the extrusion cylinder 116, the blank plate 21, and the rotating table 12 rotate synchronously, the extrusion cylinder 116 and the first piston rod 133 rotate relative to each other, that is, the coil 171 and the magnet 172 move relative to each other, and the coil 171 cuts the magnetic flux lines of the magnet 172 to generate an electromotive force, see Figure 3 When the rotary wheel 15 moves to the pre-working position and the rotary wheel 15 abuts against the blank plate 21, current will flow through the current detection device 19, and then the rotary wheel 15 will cut and rotate the blank plate 21 under the action of the third oil cylinder 165. When the rotary wheel 15 moves to the pre-working position and there is a gap between the rotary wheel 15 and the blank plate 21, no current will flow through the current detection device 19, and the alarm 18 will sound an alarm to remind the operator to replace the rotary wheel 15.

[0058] As an implementation method, the rotating mechanism 14 includes a driven wheel 141 fixedly connected to the rotating table 12, a motor 142 arranged on the lower side of the base 11, and a driving wheel 143 connected to the motor 142. The driving wheel 143 is connected to the driven wheel 141 through a belt 144.

[0059] Through the above arrangement, the rotating platform 12 has a larger driving force, and the motor 142 drives the rotating platform 12 to rotate through the driving wheel 143, the belt 144 and the driven wheel 141.

[0060] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
