Description

Technical Field

[0001] This utility model relates to the field of sheet metal riveting technology, specifically to a riveting device for sheet metal processing. Background Technology

[0002] Sheet metal riveting is a metal processing technology that uses riveting to firmly connect sheet metal parts (metal sheets) with other components (such as nuts, bolts, structural parts, etc.). It is widely used in the automotive, home appliance, electronic equipment, communication equipment, and aerospace industries. Riveting uses the pressure generated by a riveting machine (or riveting machine) to press a rivet into a pre-made hole from one side. The plastic deformation of the rivet forms a "rivet head", thereby fixing the connected parts into a whole.

[0003] Chinese patent CN221494977U discloses a sheet metal riveting device for sheet metal processing. The key technical features include a base and a riveting machine fixedly mounted on the base. A material tray is fixedly mounted on the base, and a groove is formed in the middle of the material tray. A slider that can slide along the length of the groove is movably mounted within the groove. A rotary motor is fixedly mounted on the top of the slider, passing through the material tray and having a rotating rod fixedly mounted at its output end. The top of the rotating rod has a clamping structure for fitting two workpieces together, and clamping structures for aligning the two workpieces are provided on both sides of the rotating rod. In this invention, two sets of clamping rods are fixed in position by mutual contact, and a tension spring between the two sets of clamping rods keeps them clamped around the workpiece. After the workpiece is fixed, the rotary motor is started, causing the rivet holes around the workpiece to move to the working position of the riveting machine for riveting, thereby improving both riveting production efficiency and accuracy.

[0004] The above technical solution has the following drawbacks in use: When performing riveting on the surface of sheet metal, the pre-drilled holes on the sheet metal surface need to be accurately aligned with the hammers on the riveting machine so that the rivets can pass through the sheet metal accurately. When processing in batches, even if the sheet metal is the same size and the pre-drilled holes are in the same position, the hole alignment work is still required, which is time-consuming and results in slow work efficiency.

[0026] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0027] like Figures 1 to 5As shown, an embodiment of this utility model provides a riveting device for sheet metal processing, including: a riveting machine body 1, a cylinder 2 connected to the surface of the riveting machine body 1, and a pressure hammer 3 fixedly connected to the output end of the cylinder 2; when the sheet metal needs to be riveted, the worker places the sheet metal under the pressure hammer 3 and aligns the pre-drilled holes on the sheet metal with the pressure hammer 3, then the cylinder 2 drives the pressure hammer 3 to run, and the pressure hammer 3 presses and deforms the rivets in the holes of the sheet metal, thereby fixing the rivets on the sheet metal and completing the riveting operation; a limiting device 4 is provided on the surface of the riveting machine body 1, and the limiting device 4 includes a processing table 41 fixedly connected to the surface of the riveting machine body 1, a baffle a44 connected to the surface of the processing table 41, and a baffle b45 connected to the surface of the processing table 41, and the baffle b45 slides on the surface of the baffle a44.

[0028] like Figures 2 to 3 As shown, the limiting device 4 is installed on the surface of the pressing machine body 1. The limiting device 4 includes a processing table 41 fixedly connected to the surface of the pressing machine body 1. A baffle a44 and a baffle b45 are connected to the surface of the processing table 41. The baffle b45 slides on the surface of the baffle a44. When continuous pressing operations are required on sheet metal of the same size, in order to quickly align the holes on the sheet metal with the pressing hammer 3, the operator uses a rocker arm 42 to rotate the adjusting screw 43. As the adjusting screw 43 rotates continuously, it drives the slider 431 in the slide groove 411 to move. The baffle a44 on the slider 431 also moves accordingly until the holes on the sheet metal are aligned with the pressing hammer 3. The hole is parallel to the pressure hammer 3 laterally. The limiting device 4 also includes an adjusting screw 43, which is rotatably connected to the processing table 41. The surface of the processing table 41 is provided with a sliding groove 411. A slider 431 is slidably connected to the inner wall of the sliding groove 411. The slider 431 is threadedly connected to the adjusting screw 43. The baffle a44 and the slider 431 are detachably installed. By sliding the baffle b45, the position of the baffle b45 is adjusted. When the worker places the sheet metal, the diagonal of the sheet metal is placed against the position of the baffle a44 and the baffle b45. The hole reserved on the sheet metal is aligned with the position of the pressure hammer 3, which makes it convenient for the worker to align the sheet metal part with the position of the pressure hammer 3, thereby improving the processing efficiency of sheet metal pressing.

[0029] like Figure 4As shown, one end of the adjusting screw 43 is fixedly connected to an adapter block 432. A rocker arm 42 is detachably mounted on the surface of the adapter block 432. A handle 421 is fixedly connected to the surface of the rocker arm 42. When it is necessary to align and limit both sides simultaneously, the operator can remove one side of the rocker arm 42, then align the cross block 422 on the rocker arm 42 with the cross groove 433 on the other side of the adapter block 432, and insert the cross block 422 into the cross groove 433 to engage it. Then, when the rocker arm 42 is rotated... The adjusting screw 43 will be driven, and the inner wall of the baffle b45 is threaded with a fixing screw 451. One end of the fixing screw 451 is fixedly connected to a screw block 452. One end of the fixing screw 451 abuts against the surface of the baffle a44. After the position of the baffle b is also adjusted, the operator rotates the fixing screw 451 by screw block 452. As the fixing screw 451 rotates continuously, it will abut against the top of the baffle a44, thus fixing the position of the baffle b45.

[0030] like Figures 4 to 5 As shown, a cross block 422 is fixedly connected to the surface of the rocker arm 42, and a cross groove 433 is opened on the surface of the adapter block 432. The size of the cross block 422 is adapted to the size of the cross groove 433. An insert block 441 is fixedly connected to the surface of the baffle a44, and a slot is opened on the surface of the slider 431. The size of the slot is adapted to the size of the insert block 441. When the baffle a44 and the baffle b45 are not needed, the insert block 441 on the baffle a44 is pulled out from the slider 431. At this time, the processing table 41 forms a plane, which can place a larger sheet metal plate. The surface of the insert block 441 is chamfered, and the surface of the cross block 422 is chamfered. The chamfered insert block 441 and the cross block 422 make the edge of one side inserted into the slot beveled, making it easier to insert into the slot.

[0031] like Figure 6As shown, a limiting block 46 is fixedly connected to the surface of the processing table 41. A limiting screw 462 is threadedly connected to the inner wall of the limiting block 46. A pressure plate 461 is rotatably connected to one end of the limiting screw 462. A guide rod 463 is fixedly connected to the surface of the pressure plate 461. The guide rod 463 is slidably connected to the limiting block 46. A rubber pad is fixedly connected to the surface of the pressure plate 461. The surface of the adapter block 432 is provided with anti-slip texture. After adjusting the position of the adjusting screw 43, the rocker arm 42 is detached from one end of the adjusting screw 43. Then, by rotating the limiting screw 462, the rocker arm 462 rotates to adjust the position of the limiting screw 462. With the limit screw 462 in place, the pressure plate 461 will move as the limit screw 462 rotates continuously until the pressure plate 461 is in contact with the arc surface of the adapter block 432. The rubber on the surface of the pressure plate 461 is in contact with the anti-slip texture on the surface of the adapter block 432, which increases the friction between the pressure plate 461 and the surface of the adapter block 432, thereby fixing the adjustment screw 43 and preventing the adjustment screw 43 from rotating due to vibration generated during equipment operation. The rubber pad in the middle not only increases the friction but also buffers the vibration, making the limit screw 462 less prone to loosening, thus achieving a stable fixing effect.

[0032] Among them, baffle b45 is composed of an irregular slider that slides on baffle a44 and the baffle. The slider can only slide on baffle a44 and will not fall off. The rectangular block inside the slider is locked in the sliding hole on the baffle, so it will not detach (this slider and slider 431 are not the same part). Two screw dust sleeves can be installed on the arc surface of adjusting screw 43 and on both sides of slider 431. The dust sleeves can extend and retract freely, and the two ends of the dust sleeves are fixed (one side is bonded to the inner wall of the slide groove 411, and the other side is bonded to the surface of slider 431). This makes it difficult for dust to accumulate in the thread of adjusting screw 43. This equipment needs to be maintained regularly or irregularly (cleaning or lubricating parts), including dust that has accumulated in its slide groove 411 for a long time, lubrication of adjusting screw 43, and some metal shavings generated during processing, to prevent adjusting screw 43 from jamming, and timely replacement of vulnerable parts.

[0033] In this embodiment of the utility model, the willow pressing machine body 1 adopts the fully intelligent riveting machine model 6T-500 produced by Shenzhen Maisike Technology Co., Ltd. Since the structure and operating principle of this model of willow pressing machine body 1 are existing technologies, its structure and operating principle need not be described in detail.

[0034] Working principle: When the sheet metal needs to be pressed, the worker places the sheet metal under the pressing hammer 3 and aligns the pre-drilled holes on the sheet metal with the pressing hammer 3. Then, the cylinder 2 drives the pressing hammer 3 to run, and the pressing hammer 3 presses and deforms the rivets in the holes of the sheet metal, thereby fixing the rivets on the sheet metal and completing the pressing operation.

[0035] When continuous pressing operations are required on sheet metal of the same size, in order to quickly align the holes on the sheet metal with the pressing hammer 3, the operator uses a rocker arm 42 to rotate the adjusting screw 43. As the adjusting screw 43 rotates continuously, it drives the slider 431 in the slide groove 411 to move, and the baffle a44 on the slider 431 also moves accordingly, until the holes on the sheet metal are horizontally parallel to the pressing hammer 3. Then, by sliding the baffle b45, the position of the baffle b45 is adjusted. After the position of the baffle b is also adjusted, the operator uses a screw block 452 to rotate the fixing screw 451. As the fixing screw 451 rotates continuously, it is until the fixing screw 451 abuts against the baffle a44, thereby fixing the position of the baffle b45. At this time, when the operator places the sheet metal, the diagonal of the sheet metal abuts against the positions of the baffle a44 and the baffle b45, and the reserved holes on the sheet metal are aligned with the position of the pressing hammer 3, which makes it convenient for the operator to align the sheet metal parts with the position of the pressing hammer 3, thereby improving the processing efficiency of sheet metal pressing operations.

[0036] When both sides need to be aligned and limited simultaneously, the operator can remove the rocker arm 42 on one side, then align the cross block 422 on the rocker arm 42 with the cross groove 433 on the adapter block 432 on the other side, and insert the cross block 422 into the cross groove 433 to engage it. Then, when the rocker arm 42 is rotated, the adjusting screw 43 will be driven. When the baffle a44 and baffle b45 are not needed, the insert block 441 on the baffle a44 is pulled out from the slider 431. At this time, the processing table 41 forms a plane, which can place larger sheet metal plates (for larger sheet metal plates, it is recommended to use large pressing equipment for processing to avoid non-compliant willow heads after pressing, which will lead to the failure of the pressing operation).

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
