Description

Technical Field

[0001] This invention relates to the field of steel cap processing technology, specifically to a shaping device for steel cap processing and its usage method. Background Technology

[0002] In the power industry, steel caps also play a crucial role, especially in power fittings. Steel caps are often used as important components to protect power lines and equipment, effectively preventing damage to the lines caused by external factors, thereby ensuring the stable operation of the power system.

[0003] The current steel cap manufacturing process generally requires a stamping process, which can be divided into separation processes (such as punching and blanking) and forming processes (such as bending and deformation), with shaping being a type of forming process. Traditional steel cap manufacturing relies on casting or step-by-step stamping processes, but these have the following problems: process fragmentation: separation and forming processes need to be completed in steps on different equipment, resulting in time-consuming transfer and accumulated positioning errors, affecting the fitting accuracy between the cap body and the base; inefficient waste disposal: the annular waste material after stamping is easily stuck on the outside of the mold, requiring manual cleaning, which not only reduces efficiency but may also scratch the surface of the finished product. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a shaping device for steel cap processing and its usage method.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A shaping device for processing steel caps includes a base and further includes:

[0007] A stamping assembly, fixed on a base, is used for stamping blanks;

[0008] A rotating disk is rotatably connected to a base, and a drive motor for driving the rotating disk to rotate is provided on the base;

[0010] And a blanking assembly, which is disposed in the punch holder and is used to push the stamped cap body out of the punch;

[0011] The base is provided with a material unloading guide.

[0012] Preferably, the stamping assembly includes a support fixed on the base, a main hydraulic cylinder fixedly connected to the support, and a die seat connected to the piston rod of the main hydraulic cylinder. The die seat and the punch seat abut against each other to stamp the blank into a cap body.

[0013] Preferably, the die holder includes a recess connected to the piston rod of the main hydraulic cylinder, a sleeve slidably connected to the outside of the recess, and an auxiliary hydraulic cylinder disposed between the sleeve and the recess. An annular cutter is provided on the lower side of the sleeve.

A first elastic element is provided between the bottom wall of the top plate and the top wall of the recess, and a receiving groove for accommodating the bottom plate is provided on the inner wall of the recess.

[0015] Preferably, the punch seat is provided with a limiting component for limiting the displacement range of the blank. The limiting component includes a first elastic telescopic rod evenly arranged in a circle on the punch seat and a limiting rod fixed to the top of the first elastic telescopic rod. When the first elastic telescopic rod is not compressed, the height of the top of the limiting rod is higher than the height of the punch seat.

[0016] Preferably, an L-shaped insert plate is slidably connected to the limiting rod, a second elastic telescopic rod is provided between the L-shaped insert plate and the limiting rod, and a limiting transverse groove is provided on the punch seat to insert into the L-shaped insert plate.

[0017] Preferably, a third elastic telescopic rod is fixedly provided at the bottom of the recess, and a pressure plate is fixedly provided at the bottom of the third elastic telescopic rod to move against the top of the limiting rod. A side cutting blade is fixedly provided on the annular cutter, a fixed seat that cooperates with the side cutting blade is fixedly provided on the L-shaped insert plate, and a waste spiral guide groove is fixedly provided on the outer wall of the punch seat.

[0018] Preferably, the blanking assembly includes a movable rod slidably connected in the punch seat, a push rod slidably connected in the limiting transverse groove, a first connecting rod hinged between the push rod and the movable rod, a top rod vertically slidably connected in the punch seat, and a second connecting rod hinged between the top rod and the push rod, wherein the push rod movably abuts against the L-shaped insert plate.

[0019] Preferably, a fixed plate is fixedly provided on the outer side of the moving rod, a movable groove for sliding of the fixed plate is provided on the punch seat, a second elastic element is provided between the inner wall of the movable groove and the fixed plate, an annular groove for sliding of the moving rod is provided on the base, an abutment block is fixedly provided in the annular groove, and an inclined abutment surface that cooperates with the abutment block is provided at the bottom of the moving rod.

[0020] The present invention also discloses a method of using a shaping device for steel cap processing, comprising the following steps:

[0021] S1: Place the steel cap blank on the top of the punch seat of the rotating disk and fix it by multiple limit rods to prevent the blank from slipping;

[0022] S2: Start the drive motor to rotate the rotating disk, so that the punch holder moves to the bottom of the stamping assembly in sequence. After it is in place, the drive motor stops.

[0023] S3: The main hydraulic cylinder pushes the die holder downwards;

[0024] Pre-compression stage: The recessed seat contacts the blank, the bottom plate is compressed and retracts into the receiving groove, the first elastic element is stretched, and then the recessed seat continues to press down on the blank to form a cap structure;

[0025] Trimming stage: The auxiliary hydraulic cylinder drives the sleeve to continue moving downward, and the annular cutter removes the excess waste material on the outer ring of the punch seat;

[0026] S4: The pressure plate presses down on the limiting rod, the first elastic telescopic rod is compressed, and when the height of the L-shaped insert plate is flush with the height of the limiting transverse groove, the L-shaped insert plate is pushed into the limiting transverse groove by the second elastic telescopic rod, locking the height of the limiting rod;

[0027] The side cutter continues to move down to engage with the fixed seat, cutting the annular waste into arc-shaped fragments, which then slide down the waste spiral guide groove to the unloading guide table for recycling;

[0028] S5: The die holder moves upward, and the base plate pushes the cap body downward under the action of the first elastic element to prevent sticking;

[0029] S6: Then the drive motor continues to run, the rotating disk drives the punch seat that has been stamped and shaped to rotate to the position of the abutting block, the moving rod is pushed up, and the push rod is pushed through the first connecting rod. The second connecting rod drives the push rod to push out the cap body and fall into the collection box placed on the side.

[0030] As the push rod continues to move laterally within the limiting transverse groove, it pushes the L-shaped insert plate out of the limiting transverse groove, the first elastic telescopic rod is released, and the limiting rod is reset to a position higher than the punch seat, ready for the next blank to be placed.

[0031] As can be seen from the above technical solutions, the present invention has the following beneficial effects:

[0032] 1. In this invention, multiple punch seats are arranged circumferentially on a rotating disk, enabling multi-station collaborative work and achieving seamless connection between stamping, shaping, and blanking processes. The main hydraulic cylinder drives the concave seat to press down, working together with the punch seats to extrude the blank and complete the plastic shaping of the main body of the cap. The sleeve seat lags behind the edge trimming stage. After the concave seat is in place, the auxiliary hydraulic cylinder is activated to push the sleeve seat to continue moving down. The annular cutter shears the waste material on the outer edge of the punch seat at high speed, eliminating the positioning error of traditional step-by-step processing and ensuring the processing quality and efficiency of the steel cap.

[0033] 2. In this invention, when the die seat is pressed down, the annular cutter cuts off the outer edge of the blank to form annular waste. The annular waste is temporarily stored on the outside of the punch seat. As the die seat continues to move down, the side cutter moves down with the die seat and forms a shearing force with the fixed seat, cutting the annular waste into multiple arc-shaped fragments. This solves the problem that the annular waste is easy to accumulate on the outside of the punch seat. The cut waste is automatically guided by the spiral guide groove to realize automatic waste recycling, avoid manual intervention, and reduce the workload of the workers.

[0034] 3. In this invention, when the recess moves downward, the base plate abuts against the blank at the top of the punch seat, the base plate moves upward under force and retracts into the receiving groove, and the bottom wall of the base plate adapts to the inner wall of the cavity at the bottom of the recess; when the blank is stamped and shaped into a cap, the die seat moves upward, the first elastic element drives the base plate to reset, so that the base plate pushes the cap downward, effectively preventing the cap from moving upward with the recess and ensuring that the subsequent stamping assembly proceeds normally;

[0035] 4. In this invention, by setting a limiting rod and making its height higher than the punch seat, the blank can be stably placed on the punch seat to avoid slipping. At the same time, the height of the limiting rod is locked by the linkage between the L-shaped insert plate and the limiting transverse groove to ensure that the height of the limiting rod is lower than the cap body after stamping, thus avoiding material cutting interference.

[0036] 5. In this invention, when the punch seat that has completed the stamping and shaping rotates with the rotating disk to the abutment block position, the inclined surface at the bottom of the moving rod is lifted by the abutment block, the moving rod moves upward to compress the second elastic element, the moving rod moves upward to push the first connecting rod, the first connecting rod drives the push rod to slide horizontally along the limiting transverse groove, the push rod will push the top rod upward through the second connecting rod, pushing the cap body away from the surface of the punch seat, so that the cap body tilts and falls; as the push rod continues to move horizontally, the end of the push rod abuts the L-shaped insert plate, the L-shaped insert plate exits the limiting transverse groove, and the limiting rod springs back to the high position under the action of the first elastic telescopic rod, preparing for the placement of the next blank, thus realizing the continuous stamping and shaping of the steel cap.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0053] Reference Figure 1 and Figure 2 This embodiment provides a shaping device for steel cap processing, including a base 1, and further including: a stamping assembly 2, a rotating disk 3, a punch seat 4, and a blanking assembly; the stamping assembly 2 is fixed on the base 1 and is used for stamping blanks; the rotating disk 3 is rotatably connected to the base 1, and a drive motor 101 for driving the rotating disk 3 to rotate is provided on the base 1; the punch seat 4 is evenly arranged in a circle on the rotating disk 3 and is used to place blanks; the blanking assembly is arranged in the punch seat 4 and is used to push the stamped cap body out of the blank; wherein, a blanking guide 102 is provided on the base 1; the rotating disk 3 achieves circumferential motion through the drive motor 101, driving multiple punch seats 4 to enter the stamping station in sequence to form a continuous operation cycle, each punch seat 4 carrying one blank, realizing the parallel operation of "loading-stamping-unloading";

[0054] Specifically, after the blank is placed on top of the punch seat 4, the drive motor 101 drives the rotating disk 3 to rotate relative to the base 1, so that the punch seats 4 enter the stamping station in sequence. When one of the punch seats 4 moves the blank to the stamping station, that is, moves to the underside of the stamping assembly 2, the stamping assembly 2 stamps and shapes the blank on the punch seat 4. After the blank at the stamping station is stamped and shaped, the stamping assembly 2 resets, and then the drive motor 101 drives the rotating disk 3 to rotate again, so that the other rotating disk 3 moves to the stamping station to stamp and shape another blank. The blank that has been stamped and shaped is automatically unloaded after moving to the other side. This application realizes integrated stamping and shaping processing by integrating stamping, trimming and scrap handling functions, which solves the problems of process interruption, scrap retention and loss of accuracy control of transfer error in steel cap processing, and ensures the processing quality and efficiency of steel cap.

[0055] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 11 As a preferred technical solution in this embodiment, the stamping assembly 2 includes a support 201 fixed on the base 1, a main hydraulic cylinder 202 fixedly connected to the support 201, and a die seat 203 connected to the piston rod of the main hydraulic cylinder 202. The die seat 203 and the punch seat 4 abut against each other to stamp the blank into a cap. The support 201 serves as a load-bearing base and is fixed to the base 1 by high-strength bolts. It must meet the impact rigidity requirements. The main hydraulic cylinder 202 provides the main stamping pressure.

[0056] Furthermore, the die holder 203 is designed in layers. The die holder 203 includes a recess 2032 connected to the piston rod of the main hydraulic cylinder 202, a sleeve 2031 slidably connected to the outside of the recess 2032, and an auxiliary hydraulic cylinder 2033 disposed between the sleeve 2031 and the recess 2032. A ring cutter 2034 is provided on the lower side of the sleeve 2031. The ring cutter 2034 adopts a replaceable blade design. The bottom cavity of the recess 2032 cooperates with the top boss of the punch holder 4 to complete the plastic shaping of the cap body. The sleeve 2031 is slidably nested on the outside of the recess 2032 and is independently driven by the auxiliary hydraulic cylinder 2033, lagging behind the movement of the recess 2032.

[0057] Specifically, in the pre-compression forming stage: the main hydraulic cylinder 202 drives the concave seat 2032 to press down, and together with the punch seat 4, they extrude the blank to complete the plastic shaping of the main body of the cap; in the delayed trimming stage of the sleeve seat 2031: after the concave seat 2032 is in place, the auxiliary hydraulic cylinder 2033 starts and pushes the sleeve seat 2031 to continue to move down, and the annular cutter 2034 shears the waste material on the outer edge of the punch seat 4 at high speed. The sheared waste material may be an arc-shaped strip or annular waste material sleeved on the outside of the punch seat 4;

[0058] It should be noted that, in order to prevent the shaped cap from filling the lower cavity of the recess 2032 when the recess 2032 is pressed down, a sliding rod 5 is slidably connected inside the recess 2032. A bottom plate 501 and a top plate 502 are respectively provided at both ends of the sliding rod 5. A first elastic element 503 is provided between the bottom wall of the top plate 502 and the top wall of the recess 2032. The first elastic element 503 is a spring. A receiving groove 504 for accommodating the bottom plate 501 is opened on the inner wall of the recess 2032.

[0059] Specifically, when the recess 2032 moves downward, the base plate 501 abuts against the blank at the top of the punch 4. The base plate 501 moves upward under force and retracts into the receiving groove 504. The bottom wall of the base plate 501 is adapted to the inner wall of the bottom cavity of the recess 2032. After the blank is stamped and shaped into a cap, the die 203 moves upward, and the first elastic element 503 drives the base plate 501 to reset, so that the base plate 501 pushes the cap downward, effectively preventing the cap from moving upward with the recess 2032 and ensuring the normal operation of the subsequent stamping assembly 2.

[0060] Reference Figure 3 , Figure 4 and Figure 7 As a preferred technical solution in this embodiment, the punch seat 4 is provided with a limiting component for limiting the displacement range of the blank. The limiting component includes a first elastic telescopic rod 6 evenly arranged in a circle on the punch seat 4 and a limiting rod 601 fixed to the top of the first elastic telescopic rod 6. When the first elastic telescopic rod 6 is not compressed, the height of the top of the limiting rod 601 is higher than the height of the punch seat 4.

[0061] Specifically, the first elastic telescopic rod 6 is evenly distributed around the outer edge of the punch seat 4. A compression spring is installed inside the rod. In the initial state, the spring is in a freely extended state, pushing the top of the limiting rod 601 above the working plane of the punch seat 4, forming a closed limiting area for the blank, preventing the blank from slipping off the protruding part of the punch seat 4. When the die seat 203 presses down to contact the blank, the limiting rod 601 moves down under the reaction force of the blank, the first elastic telescopic rod 6 is compressed, and the spring stores energy. At this time, the limiting rod 601 still provides lateral constraint to ensure that the center of the blank is aligned.

[0062] It should be noted that, in order to avoid the limit rod 601 restricting the unloading of the cap body after the stamping assembly 2 has finished stamping and shaping the blank, an L-shaped insert plate 7 is laterally slidably connected to the limit rod 601, and a second elastic telescopic rod 701 is provided between the L-shaped insert plate 7 and the limit rod 601. The punch seat 4 is provided with a limiting transverse groove 401 that is inserted into the L-shaped insert plate 7. The die seat 203 continues to move down and pushes the limit rod 601 to the lowest position. At this time, the top of the limit rod 601 is lower than the bottom surface of the cap body, and the L-shaped insert plate 7 is flush with the limiting transverse groove 401. Under the elastic force of the stretched second elastic telescopic rod 701, the L-shaped insert plate 7 is inserted into the limiting transverse groove 401, locking the height of the limit rod 601 at this time, making room for the unloading of the cap body. A ball bearing should be provided at the end of the L-shaped insert plate 7 near the punch seat 4 to reduce the wear between the L-shaped insert plate 7 and the punch seat 4.

[0063] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 As a preferred technical solution in this embodiment, a third elastic telescopic rod 8 is fixedly provided at the bottom of the recess 2032, and a pressure plate 801 is fixedly provided at the bottom of the third elastic telescopic rod 8 to move against the top of the limiting rod 601. A side cutting blade 9 is fixedly provided on the annular cutter 2034, and a fixed seat 702 that cooperates with the side cutting blade 9 is fixedly provided on the L-shaped insert plate 7. The fixed seat 702 is welded to the L-shaped insert plate 7 and forms a shearing relationship with the side cutting blade 9. A V-shaped guide groove should be provided at the top of the fixed seat 702 to guide the side cutting blade 9 to accurately cut into the waste material. A waste material spiral guide groove 402 is fixedly provided on the outer wall of the punch seat 4. The end of the waste material spiral guide groove 402 extends to the unloading guide table 102 to automatically guide the waste material fragments by gravity. The spring stiffness coefficient inside the third elastic telescopic rod 8 is greater than that of the spring of the first elastic telescopic rod 6 to ensure that the pressure plate 801 presses down on the limiting rod 601 first during stamping.

[0064] Specifically, in the stamping and trimming stage: the die holder 203 presses down, and the annular cutter 2034 cuts off the outer edge of the blank to form an annular scrap, which is temporarily stored on the outside of the punch holder 4; limit locking trigger: the die holder 2032 continues to move down, the pressure plate 801 contacts the top of the limit rod 601, the third elastic telescopic rod 8 is compressed, the limit rod 601 moves down, and then the L-shaped insert 7 is inserted into the limit transverse groove 401 to lock the limit height; scrap cutting and guiding: the side cutter 9 follows the die holder 2032 032 moves down, forming a shearing force with the fixed seat 702, cutting the annular waste into multiple arc-shaped fragments. The fragments slide down along the waste spiral guide groove 402 to the unloading guide table 102, achieving automatic recycling and avoiding fragments remaining on the outside of the punch seat 4; Reset preparation: After the die seat 203 moves up, the third elastic telescopic rod 8 is released, and the pressure plate 801 disengages from the limit rod 601, but the limit height of the limit rod 601 is still locked by the L-shaped insert plate 7 until the unloading station triggers the unlocking.

[0065] Reference Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 9 and Figure 10 As a preferred technical solution in this embodiment, the unloading assembly includes a movable rod 10 slidably connected in the punch seat 4, a push rod 11 slidably connected in the limiting transverse groove 401, a first connecting rod 12 hinged between the push rod 11 and the movable rod 10, a top rod 13 vertically slidably connected in the punch seat 4, and a second connecting rod 14 hinged between the top rod 13 and the push rod 11. The push rod 11 moves against the L-shaped insert plate 7.

[0066] Furthermore, a fixed plate 1001 is fixedly provided on the outer side of the moving rod 10, and a movable groove 15 for sliding of the fixed plate 1001 is provided on the punch seat 4. A second elastic element 151 is provided between the inner wall of the movable groove 15 and the fixed plate 1001. The second elastic element 151 provides a reset elastic force to ensure that the moving rod 10 remains in a low position under normal conditions. The second elastic element 151 is set as a spring. An annular groove 16 for sliding of the moving rod 10 is provided on the base 1. An abutment block 161 is fixedly provided in the annular groove 16. An inclined abutment surface that cooperates with the abutment block 161 is provided at the bottom of the moving rod 10. The bottom of the moving rod 10 is machined into an inclined surface, which wedges with the abutment block 161 in the annular groove 16 to achieve low-friction lifting.

[0067] Specifically, the punch seat 4, which has completed the stamping and shaping, rotates with the rotating disk 3 to the abutment block 161 station. The operator can set up a collection box on one side of the base 1 to collect the cap body that has been pushed out. The bottom inclined surface of the moving rod 10 is lifted by the abutment block 161. The moving rod 10 moves upward to compress the second elastic element 151. The moving rod 10 moves upward to push the first connecting rod 12. The first connecting rod 12 drives the push rod 11 to slide horizontally along the limiting transverse groove 401. The push rod 11 will push the push rod 13 upward through the second connecting rod 14, pushing the cap body away from the surface of the punch seat 4. The cap body tilts and falls into the collection box. As the push rod 11 continues to move horizontally, the end of the push rod 11 presses against the L-shaped insert 7. The L-shaped insert 7 exits the limiting transverse groove 401. The limiting rod 601 springs back to the high position under the action of the first elastic telescopic rod 6, preparing for the placement of the next blank.

[0068] The present invention also discloses a method of using a shaping device for steel cap processing, comprising the following steps:

[0069] S1: Place the steel cap blank on the top of the punch seat 4 of the rotating disk 3, and fix it by multiple limiting rods 601 to prevent the blank from slipping;

[0070] S2: Start the drive motor 101 to drive the rotating disk 3 to rotate, so that the punch seat 4 moves to the bottom of the stamping assembly 2 in sequence. After it is in place, the drive motor 101 stops.

[0071] S3: The main hydraulic cylinder 202 pushes the die holder 203 downward;

[0072] Pre-compression stage: The recess 2032 contacts the blank, the bottom plate 501 is compressed and retracts to the receiving groove 504, the first elastic element 503 is stretched, and then the recess 2032 continues to press down on the blank to form a cap structure.

[0073] Trimming stage: The auxiliary hydraulic cylinder 2033 drives the sleeve 2031 to continue to move down, and the annular cutter 2034 removes the excess waste material on the outer ring of the punch seat 4;

[0074] S4: Pressing down the limiting rod 601 with the pressure plate 801, the first elastic telescopic rod 6 is compressed, and when the height of the L-shaped insert 7 is flush with the height of the limiting transverse groove 401, the L-shaped insert 7 is pushed into the limiting transverse groove 401 by the second elastic telescopic rod 701, locking the height of the limiting rod 601.

[0075] The side cutter 9 continues to move down to cooperate with the fixed seat 702, cutting the annular waste into arc-shaped fragments, which slide down through the waste spiral guide groove 402 to the unloading guide table 102 for recycling;

[0076] S5: The die holder 203 moves upward, and the base plate 501 pushes the cap body downward under the action of the first elastic element 503 to prevent sticking;

[0077] S6: Then the drive motor 101 continues to run, the rotating disk 3 drives the punch seat 4, which has been stamped and shaped, to rotate to the position of the abutment block 161, the moving rod 10 is pushed up, and pushes the push rod 11 through the first connecting rod 12, and the second connecting rod 14 drives the push rod 13 to push out the cap body and fall into the collection box placed on one side.

[0078] As the push rod 11 continues to move laterally within the limiting transverse groove 401, the push rod 11 pushes the L-shaped insert plate 7 out of the limiting transverse groove 401, the first elastic telescopic rod 6 is released, and the limiting rod 601 is reset to a position higher than the punch seat 4, ready for the next blank to be placed.
