Description

Technical Field

[0001] The present invention relates to the technical field of stamping production, and specifically relates to a stamping device for producing a reducer housing. Background Technique

[0002] Stamping production is an important industrial manufacturing method. It uses molds and stamping equipment to process metal sheets to form parts or components with the required shapes. Usually, the reducer housing needs to have high precision and geometric tolerances to ensure its fit and assembly accuracy with other components. Therefore, high-precision molds and stamping equipment are required during the stamping process to ensure the dimensional and shape accuracy of the housing.

[0003] However, during the stamping process, due to internal defects such as inclusions and pores in the material of the stamping sheet, they may expand due to stress concentration during the stamping process, and it is easy to form holes after stamping. This will cause the internal pressure of the finished reducer to drop, affecting the distribution of the internal lubricating oil, and accelerating the aging of the reducer. If gradually checking for holes, the work efficiency will be reduced. At the same time, after stamping, the trimmed sheet needs to be polished. If excessive iron filings and dust are generated during the polishing process, excessive inhalation of the dust will affect the physical health of the staff. Summary of the Invention

[0013] Preferably, a filter shell is fixedly mounted on a side of the punching block away from the sliding block, and the filter shell is communicated with the knife groove.

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

[0015] 1. The electric push rod drives the sliding tube to slide downward. While the sliding tube slides, the beveled rod is pushed to expand in the direction away from the sliding tube through the beveled groove, so that the sealing sleeve is synchronously expanded outward, so that the cavity between the stamping block and the stamped sheet after stamping is sealed, and then the high-pressure gas is received from the outside through the air inlet pipe and transmitted to the inside of the sliding tube, so that the notches of the gas outlet groove 1 and the gas outlet groove 2 can spray out high-pressure gas. If there are no holes on the surface of the stamped sheet for gas circulation, the high-pressure gas will push the inclined slider to slide. During the sliding process of the inclined slider, the marker pen is driven to resist and draw lines on the inner wall of the stamped sheet, thereby marking the inside of the stamped sheet, so as to determine whether there are holes inside the stamped sheet;

[0016] 2. The electric slide bar and the cutter are pushed upward by the driving cylinder and the auxiliary cylinder synchronously, so that the electric slide bar and the cutter are lifted upward and cut the lower surface of the stamping sheet. When the cutter finishes cutting the stamping sheet, the electric brush wheel will start to rotate to polish and grind the cut surface of the stamping sheet. At the same time, the cutter will also rotate slowly between the two electric slide bars, so that the cut surface of the stamping sheet can be polished and grinded. In the process of the rotation of the cutter, the contact between the blade and the grinding groove can also grind the blade of the cutter. At the same time, the sealing pad is in conflict with the lower surface of the stamping sheet, so that the dust of the electric brush wheel will be stored in the cavity of the blade groove during the polishing process to prevent the dust from splashing;

[0017] 3. The cutting knife is lifted upward to drive the slider to slide upward. During the sliding process of the slider, the L-shaped air groove is connected with the exhaust chamber, so that the high-pressure gas flowing into the sliding chamber from the intake pipe flows into the inside of the knife groove through the exhaust chamber and the L-shaped air groove. Then, the high-pressure gas will carry the dust inside the knife groove into the inside of the filter shell, and the dust will be filtered out through the filter net on the outer surface of the filter shell.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 - 12, the present invention provides a technical solution: a stamping device for the production of a reducer housing, including a base 1, a connecting frame 2 is fixedly installed on the outer side wall of the base 1, an upper pressing cylinder 3 is fixedly installed at the upper end of the connecting frame 2, and the upper pressing cylinder 3 and the center of the base 1 are on the same axis. A stamping seat 6 is fixedly installed at the upper end of the base 1. A stamping plate 7 is placed on the upper end of the stamping seat 6. An upper pressing table 4 abuts against the upper end of the stamping plate 7, and the upper end of the upper pressing table 4 is fixedly connected to the output end of the upper pressing cylinder 3. A stamping block 5 is fixedly installed at the lower end of the upper pressing table 4, and the stamping block 5 can be movably connected to the inner wall of the stamping seat 6. A sliding cavity 8 is jointly opened inside the upper pressing table 4 and the stamping block 5. A sliding tube 9 is slidably connected to the inner wall of the sliding cavity 8. An air inlet pipe 17 is fixedly installed at the top end of the inner cavity of the sliding cavity 8, and the other end of the air inlet pipe 17 extends to the outer side wall of the upper pressing table 4. The air inlet pipe 17 extending to the outer side wall of the upper pressing table 4 can be connected to the conveying pipe of high-pressure gas. High-pressure gas can be conveyed into the cavity between the sliding cavity 8 and the upper surface of the sliding tube 9 through the air inlet pipe 17. Two electric push rods 10 are fixedly installed between the sliding tube 9 and the top of the inner cavity of the sliding cavity 8. A number of bevel slots 11 are equidistantly opened on the outer side wall of the sliding tube 9. A bevel rod 12 is slidably connected to the inside of each bevel slot 11. An arc plate 15 is fixedly installed at one end of each bevel rod 12 away from the sliding tube 9. A sealing sleeve 16 is jointly sleeved on one side of each arc plate 15 away from the bevel rod 12, and the sealing sleeve 16 is movably connected to the outer side wall of the stamping block 5. An exhaust detection structure is fixedly installed at the lower end of the sliding tube 9. A support ring 31 is fixedly installed at the upper end of the base 1, and the support ring 31 and the stamping seat 6 are concentric. A cutting knife 32 is slidably connected between the support ring 31 and the stamping seat 6. A knife groove 39 is opened at the lower end of the stamping block 5, and the knife groove 39 is adapted to the cutting knife 32. A deburring structure is installed in the cavity of the knife groove 39. Two position-symmetrical abutting blocks 13 are installed on both sides of the bevel rod 12, and the abutting blocks 13 can slide inside the stamping block 5. A spring 14 is fixedly installed at one end of each abutting block 13 away from the sliding tube 9, and the spring 14 abuts against the groove wall where the abutting block 13 slides, which can reset the abutting block 13. Among them, the sealing sleeve 16 has flexibility. When the arc plate 15 does not push the sealing sleeve 16, the sealing sleeve 16 is sleeved on the inner side of the outer wall of the stamping block 5. During the process of the stamping block 5 stamping the stamping plate 7, the sealing sleeve 16 will not come into contact with the stamping plate 7.

[0035] Specifically, the upper pressing cylinder 3 is driven to drive the upper pressing table 4 and the stamping block 5 to descend together, so that the stamping plate 7 placed on the upper end of the stamping seat 6 is stamped into a cylindrical shape, as Figure 5As shown, the contact surface between the bevel groove 11 and the bevel rod 12 is a bevel. When the stamping plate 7 is stamped, the sliding tube 9 is pushed down by the electric push rod 10, so that the bevel rod 12 slides inside the bevel groove 11. Affected by the bevel of the inner wall of the bevel groove 11, as the electric push rod 10 slides downward, the bevel rod 12 will be resisted and slide in the direction away from the sliding tube 9. When the sliding tube 9 slides, the arc plate 15 will be driven to slide. The arc plate 15 then resists and pushes the sealing sleeve 16 sleeved on the outside, so that the sealing sleeve 16 expands outward and contacts the inner wall of the stamped stamping plate 7, thereby blocking the cavity between the stamping block 5 and the stamping plate 7. If there is no leak after the stamping of the stamping plate 7 is completed, the gas cannot be discharged from between the stamping block 5 and the stamping plate 7.

[0036] Among them, the exhaust detection structure includes a sleeve 19, and the sleeve 19 is fixedly connected to the lower notch of the sliding tube 9, a spring 20 is fixedly installed in the cavity of the sleeve 19, a sealing ball 21 is fixedly installed at the lower end of the spring 20, and the sealing ball 21 conflicts with the lower notch of the sleeve 19, a push rod 22 coaxial with the sleeve 19 is fixedly installed at the bottom of the inner cavity of the sliding cavity 8, and the push rod 22 can conflict with the sealing ball 21, and a plurality of vent holes are opened on the outer wall of the push rod 22, an air outlet groove 23 is opened through the lower end of the stamping block 5, and the air outlet groove 23 is connected with the push rod 22, and a plurality of air outlet grooves 231 are opened on the outer wall of the stamping block 5, Each air outlet groove 231 is connected to the air outlet groove 1 23, the outer wall of the stamping block 5 is provided with an inclined slide 24, and the lower end of the inclined slide 24 is connected to the air outlet groove 231, the inner wall of the inclined slide 24 is slidably connected with an inclined sliding block 25, and a piston 27 is fixedly installed on the upper end of the inclined sliding block 25, and a spring three 26 is fixedly installed between the inner cavity top of the inclined slide 24 and the piston 27, and an exhaust pipe 30 is provided at the inner cavity top of the inclined slide 24, and the exhaust pipe 30 bypasses the bevel rod 12 and extends to the upper end of the lower pressing table 4, and a marker pen 28 is slidably connected to the side of the inclined sliding block 25 away from the sliding cavity 8, and a spring four 29 is fixedly installed between the marker pen 28 and the inclined sliding block 25.

[0037] Specifically, when the sliding tube 9 descends, the sealing ball 21 will come into contact with the push rod 22. As the sleeve 19 and the sliding tube 9 descend together, the sealing ball 21 will move upward relative to the sleeve 19, so that the sealing ball 21 will no longer contact and block the lower notch of the sleeve 19. At this time, the high-pressure gas transmitted by the air inlet pipe 17 will gush out from the lower notch of the sleeve 19, then flow into the interior of the first air outlet groove 23 through the ventilation holes on the outer side of the push rod 22, and then disperse from the first air outlet groove 23 into the interior of the second air outlet groove 231, so that the high-pressure gas will be ejected from the notches of the first air outlet groove 23 and the second air outlet groove 231 on the lower end and the outer side of the stamping block 5. However, at this time, the cavity between the stamping block 5 and the stamping plate 7 is blocked by the sealing sleeve 16. If there are holes on the surface of the stamping plate 7, the high-pressure gas will be ejected from the holes on the stamping plate 7. If there are no holes, the high-pressure gas will push the inclined slider 25 to slide inside the inclined slideway 24, so that the air between the piston 27 and the third spring 26 will be pushed out. The pushed air will pass through the exhaust pipe 30 and be discharged from the upper notch of the exhaust pipe 30, without affecting the sealing performance between the stamping block 5 and the stamping plate 7. The inclined slideway 24 is inclined. When the inclined slider 25 slides upward inside the inclined slideway 24, the marker pen 28 will be driven to move away from the sliding cavity 8, so that the marker pen 28 will contact the inner side wall of the stamping plate 7. In order to prevent the marker pen 28 from making hard contact with the stamping plate 7, when the marker pen 28 continues to advance after contacting the stamping plate 7, the marker pen 28 will slide inside the inclined slider 25, and at the same time the fourth spring 29 will be compressed. By contacting and sliding the inner side wall of the stamping plate 7 with the marker pen 28, when the stamping plate 7 and the stamping block 5 are sealed, the marker pen 28 will mark the inner wall of the stamping plate 7 by scribing.

[0038] Among them, the deburring structure includes an exhaust cavity 44. The exhaust cavity 44 is opened inside the stamping block 5 and communicates with the sliding cavity 8. A square groove is opened at one end of the exhaust cavity 44 away from the sliding cavity 8, and the lower notch of the square groove communicates with the cutter groove 39. A slider 40 is slidably connected to the inner wall of the square groove. A fifth spring 43 is fixedly installed between the upper end of the slider 40 and the square groove. An L-shaped air groove 42 communicating with the cutter groove 39 is opened at the lower end of the slider 40, and the other end of the L-shaped air groove 42 can communicate with the exhaust cavity 44. A sharpening groove 41 adapted to the cutter 32 is opened at the lower end of the slider 40. An empty groove 37 is opened on the inner side wall of the cutter 32. A number of electric brush wheels 38 are equidistantly installed on the inner wall of the empty groove 37. A sealing gasket 321 is fixedly installed on one side of the lower notch of the empty groove 37, and the sealing gasket 321 can contact the lower end of the stamping plate 7.

[0039] Specifically, there are several brushes on the electric brush wheel 38, and the brushes are flexible. When the brushes contact the stamping plate 7, they will deform to a certain extent, so that the cut surface of the stamping plate 7 is wrapped inside the brushes. During the upward lifting process of the cutter 32, the sealing gasket 321 abuts against the lower surface of the stamping plate 7. Refer to Figure 10 , after the sealing gasket 321 abuts against the lower surface of the stamping plate 7, a sealed space will be formed between the side of the cutter 32 where the electric brush wheel 38 is installed and the inner side wall of the cutter groove 39, preventing dust from splashing when the electric brush wheel 38 polishes the stamping plate 7.

[0040] Among them, two auxiliary cylinders 36 are fixedly installed at the upper end of the base 1, and the output ends of the auxiliary cylinders 36 are slidably connected to the lower end of the cutter 32. An electric chute 33 is provided on the outer side wall of the cutter 32, and two symmetrically distributed electric slide bars 34 are slidably connected to the inner wall of the electric chute 33. Each electric slide bar 34 is slidably connected to the support ring 31. A driving cylinder 35 is fixedly installed on the lower side of the end of the electric slide bar 34 away from the cutter 32, and the lower end of the driving cylinder 35 is fixedly connected to the base 1. A filter housing 18 is fixedly installed on the side of the punching block 5 away from the slider 40, and the filter housing 18 is communicated with the cutter groove 39. The cutter 32 can rotate between the two electric slide bars 34. The driving cylinder 35 and the auxiliary cylinder 36 move synchronously. The driving cylinder 35 drives the electric slide bar 34 to move upward, and the auxiliary cylinder 36 drives the electric chute 33 to move upward, so that the cutter 32 cuts the stamping plate 7.

[0041] Specifically, by the upward sliding of the cutter 32, the blade at the upper end of the cutter 32 abuts against and cuts the lower surface of the stamping plate 7. After the cutter 32 cuts the stamping plate 7, the cutter 32 continues to move upward and will move into the cutter groove 39, and then insert into the cavity of the sharpening groove 41, driving the sharpening groove 41 to slide upward. At the same time, the sealing gasket 321 abuts against the lower surface of the stamping plate 7. Refer to Figure 10, after the cutting knife 32 is inserted into the groove of the grinding groove 41, the electric brush wheel 38 will contact the stamping plate 7. At this time, the electric brush wheel 38 starts to rotate, continuously polishing and grinding the cutting surface of the stamping plate 7 to achieve the effect of deburring. At the same time, the cutting knife 32 will also slowly rotate on the electric slide rod 34, so that the cutting surface of the stamping plate 7 is polished more evenly. At the same time, during the process of the cutting knife 32 lifting upward, the cutting knife 32 will also drive the slider 40 to slide upward. The upward sliding of the slider 40 will cause the L-shaped air groove 42 to communicate with the exhaust cavity 44. At the same time, the L-shaped air groove 42 is also connected to the tool groove 39. At this time, the high-pressure gas transmitted by the air inlet pipe 17 will flow into the interior of the tool groove 39 along the trajectory of the exhaust cavity 44 and the L-shaped air groove 42 from the cavity of the sliding cavity 8, so that the dust generated by the grinding of the electric brush wheel 38 is flushed out by the high-pressure air. The dust flows in the cavity of the tool groove 39 along with the high-pressure gas, and then converges and flows into the interior of the filter housing 18. The outer surface of the filter housing 18 is provided with a filter net. The dust flowing into the interior of the filter housing 18 will be filtered inside the filter housing 18, while the high-pressure gas will flow out smoothly.

[0042] Working principle: By pressing down the air cylinder 3 to push the pressing table 4 and the pressing block 5 to move downward, the pressing block 5 stamps the stamping plate 7 placed on the upper end of the stamping seat 6, stamping the stamping plate 7 into a cylindrical shape. Then, the electric push rod 10 drives the sliding tube 9 to slide downward. While the sliding tube 9 slides, it pushes the inclined side rod 12 to expand away from the sliding tube 9 through the inclined side groove 11, so that the sealing sleeve 16 is synchronously expanded outward, thus sealing the cavity between the pressing block 5 and the stamped stamping plate 7. Then, high-pressure gas is received from the outside through the air inlet pipe 17 and transmitted to the interior of the sliding tube 9, and then introduced into the interior of the air outlet groove one 23 and the air outlet groove two 231 through the sleeve 19, so that high-pressure gas can be ejected from the orifices of the air outlet groove one 23 and the air outlet groove two 231. However, if there are no holes on the outer surface of the stamping plate 7 for gas circulation, the high-pressure gas will push the inclined slider 25 to slide. During the sliding process of the inclined slider 25, it drives the marker pen 28 to contact and draw lines on the inner wall of the stamping plate 7, thereby marking the interior of the stamping plate 7 to determine whether there are holes inside the stamping plate 7;

[0043] Next, after the punching block 5 punches and forms the punching plate 7, the electric slide bar 34 and the cutter 32 are pushed upward by the driving cylinder 35 and the auxiliary cylinder 36, so that the electric slide bar 34 and the cutter 32 are lifted upward and cut the lower surface of the punching plate 7. After the cutter 32 has finished cutting the punching plate 7, the electric brush wheel 38 starts to rotate to polish and grind the cut surface of the punching plate 7. At the same time, the cutter 32 also rotates slowly between the two electric slide bars 34, so that the cut surface of the punching plate 7 can be polished and grinded. In the process of the rotation of the cutter 32, the blade contact with the grinding groove 41 can also grind the blade part of the cutter 32. At the same time, the sealing gasket 321 is in conflict with the lower surface of the punching plate 7, so that the dust of the electric brush wheel 38 will be stored in the cavity of the knife groove 39 during the polishing process.

[0044] Finally, the cutter 32 is lifted upward to drive the slider 40 to slide upward. During the sliding process of the slider 40, the L-shaped air groove 42 is connected to the exhaust chamber 44, so that the high-pressure gas flowing into the sliding chamber 8 from the intake pipe 17 flows into the knife groove 39 through the exhaust chamber 44 and the L-shaped air groove 42. Then, the high-pressure gas will carry the dust inside the knife groove 39 into the filter shell 18, and the dust will be filtered out through the filter net on the outer surface of the filter shell 18.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
