Description

Technical Field

[0001] This invention relates to the field of conical head forming technology, specifically to a conical head forming tooling. Background Technology

[0002] During the production and processing of conical heads, stamping equipment is used to stamp the workpiece to obtain the desired shape of the head. For small conical heads, they are generally formed by cold pressing. The stamping equipment usually includes a lower stamping seat, a stamping head, a guide column, and a hydraulic rod. The unformed head plate is placed above the mold groove of the stamping seat, and the stamping head is pushed down by the hydraulic rod to stamp the head plate, thus obtaining the formed head.

[0003] During stamping, to avoid wear and scratches on the mold, a thin film is usually laid on the mold slot of the stamping seat before stamping, then the end plate is placed, and then another thin film is laid on top of the end plate. The process of laying the film is quite troublesome. It can be done by applying stamping lubricant to both sides of the end plate. However, the existing stamping fixtures do not have the function of applying lubricant to the end plate, so workers still need to apply it temporarily, which is not conducive to batch operation on the production line. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a conical head forming fixture that allows lubricating oil to be applied to the head plate before stamping.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a conical head forming fixture, including a stamping table, a mold groove and a stamping assembly located on the stamping table, a rectangular shell embedded in the stamping table, the rectangular shell being used to temporarily hold lubricating oil, a rotating rod being rotatably installed through the rectangular shell, the stamping assembly including a lifting plate, the lifting plate being raised and lowered to control the rotation of the rotating rod, an installation rod being rotatably installed through one end of the rotating rod located inside the rectangular shell, an oil brush sleeve being sleeved on the outside of the installation rod, an oil supply assembly being provided on one side of the stamping table and communicating with both the installation rod and the rectangular shell, the lifting plate being raised and lowered to control the oil supply assembly to supply oil, a telescopic component being provided on one side of the stamping table to control the resetting of the oil supply assembly, an arc-shaped sealing plate being fixedly installed inside the rectangular shell, an opening being provided through the upper end of the arc-shaped sealing plate, a sealing component being provided at the lower end of the rotating rod to seal the opening, a pushing component being provided through the upper end of the rectangular shell to control the rotation of the installation rod, the pushing component being raised and lowered synchronously with the oil supply assembly.

[0006] Preferably, a sliding groove is provided on the outer side of the rotating rod, and the sliding groove is an arc-shaped groove and a vertical groove from top to bottom. The arc-shaped groove and the vertical groove are connected in sequence, and a slider that is slidably connected to both the arc-shaped groove and the vertical groove is fixedly installed on one side of the lifting plate.

[0007] Preferably, the mounting rod has a conical cavity inside, and the mounting rod has multiple fine holes communicating with the conical cavity on its outer side. The fine holes are used to guide lubricating oil into the brush sleeve.

[0008] Preferably, the oil delivery assembly includes a fixed housing fixedly installed on one side of the stamping table. An oil suction pipe is fixedly connected between the lower end of the fixed housing and the rectangular housing. A piston is slidably disposed inside the fixed housing. A push rod is fixedly installed on the upper end of the piston. The push rod passes through the fixed housing and is slidably connected thereto. An oil delivery pipe is fixedly connected between one side of the lower end of the fixed housing and the mounting rod. The oil delivery pipe is used to deliver lubricating oil to the conical cavity. The oil delivery pipe includes an L-shaped rigid pipe installed at one end of the mounting rod and a telescopic flexible pipe installed on one side of the fixed housing. The telescopic flexible pipe passes through the rectangular housing and is fixedly connected to the L-shaped rigid pipe.

[0009] Preferably, the sealing element includes an arc-shaped filter screen that slides in contact with the rectangular housing, a sealing block for sealing the opening is fixedly installed in the middle of the arc-shaped filter screen, a spiral collar is fixedly installed at the lower end of the rotating rod, a spiral rod is fixedly installed at the upper end of the sealing block, and the spiral collar is sleeved on the outside of the spiral rod and slidably connected to it.

[0010] Preferably, the telescopic component includes a fixed cylinder fixedly installed on the stamping table, a support cylinder slidably disposed on the upper end of the fixed cylinder, a spring fixedly disposed between the fixed cylinder and the support cylinder, and the upper end of the support cylinder being fixedly connected to the push rod.

[0011] Preferably, the pusher includes a toothed ring fixedly sleeved on the outside of the mounting rod, and a serrated rod is slidably disposed through the upper end of the rectangular housing. The upper end of the serrated rod is fixedly connected to the push rod, and the serrated rod meshes with the toothed ring.

[0012] Preferably, a screen is fixedly installed inside the rectangular shell, and the spiral collar is rotatably connected to the screen.

[0013] Preferably, the stamping assembly further includes a hydraulic rod fixedly installed on the upper end of the stamping platform, the lower end of the hydraulic rod being fixedly connected to the lifting plate, and an upper mold being fixedly installed on the lower end of the lifting plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. A rotating rod is installed through a rectangular shell, and an installation rod is installed through the rotating rod. An oil brush sleeve is fitted on the outside of the installation rod. The lifting plate is controlled to move, causing the slider to slide up and down in the arc groove. The rotating rod rotates 180 degrees clockwise and then 180 degrees counterclockwise. The material is first loaded by an external robot. When the rotating rod rotates 180 degrees, one side of the end plate is oiled. Then the robot flips the end plate over. When the rotating rod rotates 180 degrees, the other side of the end plate is oiled. Then the slider slides into the vertical groove for stamping. The whole process is simple to operate and is conducive to batch stamping on the production line.

[0016] 2. By sliding a piston inside the fixed housing, setting an oil extraction pipe between the fixed housing and the rectangular housing, and setting an oil delivery pipe between the fixed housing and the mounting rod, the lifting plate moves down, causing the slider to disengage from the arc groove. Then, the stamping moves down, the lifting plate pushes the push rod down, and the push rod drives the piston down, pushing the lubricating oil in the fixed housing into the conical cavity. The amount of oil added each time is controlled to be the same. The lifting and lowering movement of the lifting plate controls the delivery and brushing of the lubricating oil, realizing automatic, timed, and quantitative lubrication in the stamping process, reducing manual intervention and improving production efficiency.

[0017] 3. By fitting a toothed ring on the outside of the mounting rod, a serrated rod is slidably installed through the upper end of the rectangular housing. The upper end of the serrated rod is fixedly connected to the push rod. The serrated rod meshes with the toothed ring. After the lifting plate moves down and drives the slider to disengage from the arc groove, the serrated rod and the toothed ring are in a meshing state (at this time, the brush sleeve is located inside the rectangular housing. If oil seeps out during oiling, it can fall directly into the rectangular housing for recycling). Then, the pressing moves down, and the lifting plate pushes the serrated rod down, causing the mounting rod and brush sleeve to rotate, so that the lubricating oil in the conical cavity can enter the brush sleeve more evenly.

[0031] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0032] Please see Figures 1-12A conical head forming fixture includes a stamping table 1, a mold groove 5 on the stamping table 1, and a stamping assembly. A rectangular shell 3 is embedded in the stamping table 1. The rectangular shell 3 is used to temporarily store lubricating oil (the oil is drawn into the rectangular shell 3 in advance for temporary use before each stamping operation to avoid a large amount of lubricating oil being directly exposed to the air, which may evaporate or deteriorate). A rotating rod 8 is rotatably installed through the rectangular shell 3. The stamping assembly includes a lifting plate 2, which is raised and lowered to control the rotation of the rotating rod 8. The stamping assembly also includes a hydraulic rod 4 fixedly installed on the upper end of the stamping table 1. The lower end of the hydraulic rod 4 is fixedly connected to the lifting plate 2. An upper mold 6 is fixedly installed on the lower end of the lifting plate 2. An installation rod 31 is rotatably installed through one end of the rotating rod 8 inside the rectangular shell 3. An oil brush sleeve 7 is sleeved on the outside of the installation rod 31. A sliding groove is opened on the outside of the rotating rod 8. The sliding groove consists of an arc-shaped groove 15 and a vertical groove 24 from top to bottom. The arc groove 15 and the vertical groove 24 are connected in sequence. A slider 10, which is slidably connected to both the arc groove 15 and the vertical groove 24, is fixedly installed on one side of the lifting plate 2. The external robot first loads the material and places the end plate above the mold groove 5. The hydraulic rod 4 is activated to control the lifting plate 2 to move upward. The lifting plate 2 drives the slider 10 to slide in the arc groove 15. The rotating rod 8 is controlled to rotate 180 degrees. The rotating rod 8 drives the oil brush sleeve 7 to apply oil to one side of the end plate. Then the robot flips the end plate. The hydraulic rod 4 controls the lifting plate 2 to move downward. The lifting plate 2 drives the slider 10 to slide and reset in the arc groove 15. The rotating rod 8 is controlled to reverse 180 degrees. The rotating rod 8 drives the oil brush sleeve 7 to apply oil to one side of the end plate. Then the hydraulic rod 4 controls the lifting plate 2 to move downward. The slider 10 slides into the vertical groove 24 (at this time, the oil brush sleeve 7 is located in the rectangular shell 3) to perform the stamping work. The whole process is simple to operate and is conducive to batch stamping on the production line.

[0033] An oil delivery assembly is provided on one side of the stamping table 1, which communicates with both the mounting rod 31 and the rectangular housing 3. The lifting plate 2 is used to control the oil delivery of the oil delivery assembly. A conical cavity 18 is opened inside the mounting rod 31, and multiple fine holes communicating with the conical cavity 18 are opened on the outside of the mounting rod 31. The fine holes are used to guide lubricating oil into the oil brush sleeve 7. The oil delivery assembly includes a fixed housing 12 fixedly installed on one side of the stamping table 1. An oil suction pipe 11 is fixedly connected between the lower end of the fixed housing 12 and the rectangular housing 3. A piston 23 is slidably installed inside the fixed housing 12. A push rod 13 is fixedly installed on the upper end of the piston 23. The push rod 13 passes through the fixed housing 12 and is slidably connected to it. One side of the lower end of the fixed housing 12 is connected to the mounting rod 31. An oil supply pipe is fixedly connected between the rectangular housing 3 and the conical cavity 18. The oil supply pipe includes an L-shaped rigid pipe 28 installed at one end of the mounting rod 31 and a telescopic flexible pipe 27 installed on one side of the fixed housing 12. The telescopic flexible pipe 27 passes through the rectangular housing 3 and is fixedly connected to the L-shaped rigid pipe 28. When the lifting plate 2 moves the upper mold 6 down to perform the stamping operation (at this time, the slider 10 slides in the vertical groove 24), the lifting plate 2 will push the push rod 13 down during the downward movement. The push rod 13 pushes the piston 23 down, pushing the lubricating oil in the fixed housing 12 into the conical cavity 18 through the oil supply pipe. The lubricating oil in the conical cavity 18 enters the brush sleeve 7 through the fine hole to replenish the oil in the brush sleeve 7.

[0034] A telescopic component for controlling the reset of the oil delivery assembly is provided on one side of the stamping table 1. After the lifting plate 2 disengages from the push rod 13, the telescopic component pushes the piston 23 to reset. The piston 23 resets and draws the lubricating oil from the rectangular housing 3 into the fixed housing 12 through the oil extraction pipe 11. An arc-shaped sealing plate 21 is fixedly installed inside the rectangular housing 3. An opening 14 is provided through the upper end of the arc-shaped sealing plate 21. A sealing component is provided at the lower end of the rotating rod 8 to seal the opening 14. A pusher for controlling the rotation of the mounting rod 31 is provided through the upper end of the rectangular housing 3. The pusher moves up and down synchronously with the oil delivery assembly. The pusher includes a toothed ring 20 fixedly sleeved on the outside of the mounting rod 31. A serrated rod 26 is slidably provided through the upper end of the rectangular housing 3. The upper end of the serrated rod 26 is connected to the push rod 1. 3. Fixed connection: the serrated rod 26 engages with the toothed ring 20. After the lifting plate 2 moves down and drives the slider 10 to disengage from the arc groove 15, the serrated rod 26 engages with the toothed ring 20 (at this time, the oil brush sleeve 7 is located inside the rectangular shell 3. When adding oil, if there is any oil leakage, it can fall directly into the rectangular shell 3 for recycling). Then, the pressing moves down. When the lifting plate 2 pushes the push rod 13 down, it will drive the serrated rod 26 down. The serrated rod 26 drives the mounting rod 31 and the oil brush sleeve 7 to rotate, so that the lubricating oil in the conical cavity 18 can enter the oil brush sleeve 7 more evenly. After the lifting plate 2 disengages from the push rod 13, the telescopic component is also used to control the serrated rod 26 to move up and disengage from the toothed ring 20. Due to the cooperation of the L-shaped rigid tube 28 and the telescopic hose 27, the mounting rod 31 can rotate and spin.

[0035] As a further technical solution of the present invention, the sealing element includes an arc-shaped filter screen 22 that slides in contact with the rectangular housing 3. A sealing block 17 for sealing the opening 14 is fixedly installed in the middle of the arc-shaped filter screen 22. A spiral collar 30 is fixedly installed at the lower end of the rotating rod 8. A spiral rod 16 is fixedly installed at the upper end of the sealing block 17. The spiral collar 30 is sleeved on the outside of the spiral rod 16 and slidably connected to it. Since the existing lubricating oil may evaporate or deteriorate due to constant exposure, when the slider 10 slides upward in the arc-shaped groove 15, the rotating rod 8 rotates and drives the spiral collar 30. The rotation causes the spiral rod 16 to push the sealing block 17 and the arc-shaped filter screen 22 downwards, opening the opening 14. When the oil brush sleeve 7 is filled with oil, any excess oil that seeps out can fall back into the rectangular housing 3. When the slider 10 slides down in the arc-shaped groove 15, the rotating rod 8 rotates, causing the spiral sleeve 30 to reverse, which causes the spiral rod 16 to push the sealing block 17 and the arc-shaped filter screen 22 upwards, sealing the opening 14. During the subsequent stamping process, the opening 14 remains sealed. When the arc-shaped filter screen 22 moves up and down, it agitates the lubricating oil in the rectangular housing 3, reducing sedimentation.

[0036] As a further technical solution of the present invention, the telescopic component includes a fixed cylinder 25 fixedly installed on the stamping table 1, a support cylinder 9 slidably disposed on the upper end of the fixed cylinder 25, a spring 29 fixedly disposed between the fixed cylinder 25 and the support cylinder 9, and the upper end of the support cylinder 9 fixedly connected to the push rod 13. When the lifting plate 2 pushes the push rod 13 down, it will push the support cylinder 9 down, and the spring 29 will be squeezed. After the lifting plate 2 is separated from the push rod 13, the push rod 13 and the sawtooth rod 26 can be pushed back to their original positions due to the action of the spring 29.

[0037] As a further technical solution of the present invention, a screen 19 is fixedly installed inside the rectangular shell 3, and the spiral collar 30 is rotatably connected to the screen 19. During the oil delivery process, the outer side of the oil brush sleeve 7 may be contaminated with impurities. When it is moved into the rectangular shell 3, the screen 19 prevents the impurities from falling into the lubricating oil.

[0038] During work:

[0039] The external robotic arm first loads the end cap plate, placing it above the mold slot 5. The hydraulic rod 4 is activated to control the lifting plate 2 to move upwards. The lifting plate 2 drives the slider 10 to slide within the arc-shaped groove 15 (from the connection point between the arc-shaped groove 15 and the vertical groove 24 to the upper end of the arc-shaped groove 15). The rotating rod 8 is then controlled to rotate 180 degrees, causing the mounting rod 31 to rotate. The mounting rod 31 then moves the oil brush sleeve 7 to apply oil to one side of the end cap plate (the telescopic hose 27 can extend and retract during the movement of the mounting rod 31). Afterwards, the robotic arm flips the end cap plate over. During operation, hydraulic rod 4 controls the lifting plate 2 to move downwards, and the lifting plate 2 drives the slider 10 to slide and reset within the arc groove 15 (sliding from the upper end of the arc groove 15 to the connection between the arc groove 15 and the vertical groove 24). The control rod 8 is reversed 180 degrees, and the control rod 8 drives the oil brush sleeve 7 to apply oil to the other side of the end plate. Afterwards, hydraulic rod 4 controls the lifting plate 2 to move downwards, and the slider 10 slides into the vertical groove 24 (when the slider 10 is in the vertical groove 24, the oil brush sleeve 7 is in the rectangular housing 3, and the serrated rod 26 and the toothed ring 20 are in a meshing state).

[0040] When the slider 10 slides upward in the arc groove 15, the rotating rod 8 rotates, causing the spiral collar 30 to rotate, which in turn causes the spiral rod 16 to push the sealing block 17 and the arc filter screen 22 downward, opening the opening 14. When the oil brush sleeve 7 is filled with oil, any excess oil that seeps out can fall back into the rectangular housing 3. When the slider 10 slides downward in the arc groove 15, the rotating rod 8 rotates, causing the spiral collar 30 to reverse, which in turn causes the spiral rod 16 to push the sealing block 17 and the arc filter screen 22 upward, sealing the opening 14. During the subsequent stamping process, the opening 14 remains sealed. When the arc filter screen 22 moves up and down, it agitates the lubricating oil in the rectangular housing 3, reducing sedimentation.

[0041] Afterwards, the hydraulic rod 4 continues to work, and the upper mold 6 is moved down by the lifting plate 2 to perform the stamping work. When the lifting plate 2 moves down and contacts the push rod 13, it will push the push rod 13 down. The push rod 13 pushes the piston 23 down, and pushes the lubricating oil in the fixed housing 12 into the conical cavity 18 through the oil supply pipe. The lubricating oil in the conical cavity 18 enters the brush sleeve 7 through the fine hole to replenish the oil in the brush sleeve 7.

[0042] The downward movement of push rod 13 will cause the sawtooth rod 26 to move downward. The sawtooth rod 26 drives the mounting rod 31 and the brush sleeve 7 to rotate through the toothed ring 20, so that the lubricating oil in the conical cavity 18 can enter the brush sleeve 7 more evenly.

[0043] The downward movement of push rod 13 will also push support cylinder 9 downward, compressing spring 29;

[0044] After the stamping is completed, the hydraulic rod 4 drives the upper mold 6 to move upward through the lifting plate 2. After the lifting plate 2 moves upward and disengages from the push rod 13, the spring 29 can drive the push rod 13 and the sawtooth rod 26 to reset. The push rod 13 drives the piston 23 to reset, and the lubricating oil in the rectangular housing 3 is drawn into the fixed housing 12 through the oil extraction pipe 11. The whole process is simple to operate and is conducive to batch stamping work on the assembly line.

[0045] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the claims of the present invention.
