Detailed Description
As shown in fig. 1 to 5, the utility model provides a riveting device for a threaded cover plate and a sealing plate, which comprises a workbench 3 for bearing the sealing plate 1 and the threaded cover plate 2, wherein a supporting groove 4 for accommodating the inner end part of the sealing plate 1 is arranged on the upper surface of the workbench 3, the sealing plate 1 is provided with an annular turning claw 5, and the threaded cover plate 2 is provided with an annular vertical hole 6; in the utility model, the direction pointing to the vertical axis of the workbench 3 is taken as an inward direction, and the reverse direction is taken as an outward direction;
a stamping device is arranged above the workbench 3 and comprises a flattening die 7 and a turnover inner core 8;
the upper end of the flattening die 7 is provided with a power rod 9 upwards, the power rod 9 is used for being connected with an external power device, and the external power device can be an air cylinder, a hydraulic cylinder or an electric push rod and the like; the flattening die 7 is provided with an upper groove 10 with a downward opening, the upper groove 10 is internally and slidably clamped with the turnover inner core 8, and an elastic device 11 (the elastic device 11 can be a spring, and a polyurethane block is preferably adopted) is arranged between the turnover inner core 8 and the bottom of the upper groove 10 (the upper groove 10 is downward in opening and the bottom of the upper groove is upward); a radial gap is arranged between the elastic device 11 and the groove wall of the upper groove 10;
the bottom edge of the turnover inner core 8 is provided with a 45-degree chamfer structure 12 (the included angle between the 45-degree chamfer structure 12 and the horizontal plane is 45 degrees), and the vertical position of the 45-degree chamfer structure 12 corresponds to the turnover claw 5 of the sealing plate 1 and is used for impacting the turnover claw 5 downwards to a structure with an angle of 45 degrees with the horizontal plane;
the lower end of the groove wall of the upper groove 10 is provided with an arc surface 13 with a higher outside and a lower inside corresponding to the part of the turning claw 5 and is used for flattening the turning claw 5 downwards on the thread cover plate 2. When the turning claw 5 is pressed downwards by the cambered surface 13 with the high outer side and the low inner side, compared with the horizontal plane, the turning claw 5 is pressed downwards by the cambered surface 13 with the larger pressing contact surface and the contact point is easier to change, so that the lower end of the groove wall of the upper groove 10 is relatively less easy to damage.
The radial clearance provides a space for horizontal (radial) expansion of the spring means 11 when compressed, making it easier for the spring means 11 to be compressed vertically, avoiding excessive energy consumption in the event of impact due to lack of expansion space.
According to the utility model, the external power device is used for providing power for downward punching action, namely 545-degree bending of the turning claw and flattening of the turning claw 5 can be realized through the turning inner core 8 and the flattening die 7 respectively (the vertical turning claw 5 needs to be turned firstly and then can be flattened, the turning claw 5 can be retracted downwards from the vertical hole 6 without turning and cannot be flattened for riveting) and the riveting efficiency is more than twice as high as the original one (the die replacement action is saved, the power device is not required to exert force twice), and the riveting machine can be operated by a single person, so that the labor cost is reduced, the riveting efficiency is improved, the productivity is improved, and the productivity meets the increasingly expanded product requirements.
The bottom of the upper groove 10 is fixedly connected with a central rod 14, and the central rod 14 extends downwards and slides through the elastic device 11 and the turnover inner core 8; a lower central groove 15 for accommodating the central rod 14 when the punching device punches downwards is arranged at the center of the upper surface of the workbench 3 and corresponds to the central rod 14; the friction between the folding core 8 and the central rod 14 is greater than the force required to press the jaws 5 down to a configuration at 45 degrees to the horizontal. The lower surface of the folded core 8 is upwardly recessed with an upper central slot 16 for receiving the radially inner end of the threaded closure. Because the inner end of the existing screw cover plate 2 is bent upwards, the utility model prevents the lower end surface of the turnover inner core 8 from interfering with the inner end of the screw cover plate 2 during riveting processing through the upper central groove 16.
The center rod 14 slides through the elastic device 11 and the turnover inner core 8, so that the elastic device 11 and the turnover inner core 8 can be sleeved on the center rod 14 before operation, a certain friction force exists between the outer side surface of the turnover inner core 8 and the groove wall of the upper groove 10, and a friction force exists between the center of the turnover inner core 8 and the center rod 14, so that before riveting operation, the elastic device 11 and the turnover inner core 8 can be suspended above the workbench 3 by means of the friction force, and preparation is made for stamping riveting operation.
An annular gasket 17 is preferably arranged between the threaded cover plate 2 and the sealing plate 1, so that partial pressure is prevented from being damaged approximately due to irregular contact surfaces; the annular gasket 17 is preferably a rubber gasket or a polyurethane gasket.
In operation, the elastic means 11 and the folded core 8 are sleeved on the central rod 14. Placing the sealing plate 1 to be riveted on the workbench 3, and supporting the inner end part of the sealing plate 1 on the supporting groove 4; the threaded cover plate 2 to be riveted is placed on the sealing plate 1, and the turning claw 5 of the sealing plate 1 passes upwards through the vertical hole 6 of the threaded cover plate 2. Then an external power device is started, the external power device pushes the flattening die 7 to punch downwards through the power rod 9, the turning inner core 8 punches the turning claw 5 of the sealing plate 1 downwards through the bottom 45-degree chamfer structure 12 of the external power device to a structure with an angle of 45 degrees with the horizontal plane, at the moment, the turning claw 5 is already at an angle of 45 degrees, and the turning inner core 8 begins to receive the reaction force from the threaded cover plate 2 and the sealing plate 1 and cannot continue downwards; at this time, the flattening die 7 continues to move downwards, the elastic device 11 is compressed when the flattening die 7 continues to move downwards, and the lower end of the groove wall of the upper groove 10 presses the outer top of the turning claw 5 downwards until the turning claw 5 is flattened on the threaded cover plate 2, so that riveting operation is completed.
The above embodiments are only for illustrating the technical solution of the present utility model, and it should be understood by those skilled in the art that although the present utility model has been described in detail with reference to the above embodiments: modifications and equivalents may be made thereto without departing from the spirit and scope of the utility model, which is intended to be encompassed by the claims.
