Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a continuous riveting die assembly. Background Art

[0002] Riveting dies are an important component used in the manufacturing process, especially when joining metals or other hard materials, to form stable, high-quality riveted joints. These dies are designed to be used with riveting machines to ensure consistency and precision every time you rivet.

[0003] However, the existing riveting dies are usually single-operation, that is, they can only perform riveting on one part at a time, and their operating efficiency is relatively low. Summary of the invention

[0004] The utility model aims to provide a continuous riveting die assembly with high operating efficiency and compact structure in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] The cam is connected with the transmission gear of the conveyor belt support and the transmission gear of the conveyor belt support is connected with the transmission gear of the conveyor belt support and the transmission gear of the conveyor belt support is connected with the transmission gear of the conveyor belt support.

[0007] The continuous riveting die assembly creatively connects a plurality of templates in series in a hinged manner, and a part to be processed can be positioned on each template.

[0008] Since the conveyor chain formed by connecting a number of templates is sleeved on the transmission wheel 1 and the transmission wheel 2, the conveyor chain can move intermittently in an orderly manner under the action of external force.

[0009] It can be seen that the intermittent movement of the above-mentioned conveyor chain can make the workpiece on each template face the corresponding riveting column. After the external force acts on the pressure plate, the pressure plate drives the riveting column to move downward under the action of the guide assembly, and the riveting column presses the workpiece on the template to complete the riveting operation.

[0010] Since there are several riveting columns, the riveting operation is performed synchronously by the several riveting columns, which effectively improves the operation efficiency.

[0011] During the riveting process, the template will be subjected to the stamping force of the riveting column. Since the upper part of the conveyor chain is supported by the guide groove, the riveting operation can be completed stably. At the same time, the guide groove guides the conveyor chain to prevent it from running off.

[0012] Under the action of the support frame, the pressure plate can be guaranteed to move up and down smoothly.

[0013] In the above-mentioned continuous riveting die assembly, a plurality of rollers are evenly arranged in the guide cavity of the frame along the moving direction of the conveyor chain, the plurality of rollers form a sliding support unit, and the conveyor chain abuts against the sliding support unit.

[0014] In the above-mentioned continuous riveting die assembly, the number of the sliding support units is two and the two sliding support units are respectively arranged at both sides of the guide cavity, and the two sides of the above-mentioned conveying chain are respectively overlapped at the corresponding sliding support units.

[0015] Under the action of the sliding support unit, not only can the lower part of the conveyor chain be stably supported, but the friction resistance between the conveyor chain and the sliding support unit is also relatively small, which can ensure the smooth movement of the conveyor chain.

[0016] In the above-mentioned continuous riveting die assembly, two symmetrically arranged sliding support units form a support portion, the above-mentioned guide cavity has two support portions arranged in parallel up and down, and the lower part of the above-mentioned conveyor chain is limited between the two support portions.

[0017] The setting of the support part can stably support the conveyor chain and prevent the lower part of the conveyor chain from excessively sagging and swinging too much.

[0018] In the above-mentioned continuous riveting die assembly, the guide assembly includes a rod-shaped guide rod and a guide hole recessed on the frame, the upper end of the guide rod is fixedly connected to the pressure plate, and the lower end of the guide rod is embedded in the guide hole.

[0019] Since the guide rod fixedly connected to the pressing plate is embedded in the guide hole, the cooperation between the guide rod and the guide hole can enable the pressing plate to move up and down smoothly.

[0020] In the above-mentioned continuous riveting die assembly, the number of the guide rods is several, and the above-mentioned guide holes are arranged in one-to-one correspondence with the guide rods.

[0021] A plurality of guide rods and corresponding guide holes can improve the stability of the pressing plate moving up and down.

[0022] In the above-mentioned continuous riveting die assembly, the riveting column includes a rod-shaped connecting rod and a cylindrical barrel. The upper end of the connecting rod is fixedly connected to the pressure plate, and the barrel is sleeved on the connecting rod. There is a spring between the pressure plate and the barrel. Under the elastic force of the spring, the lower end of the barrel has a tendency to rest against the conveying chain.

[0023] The connecting rod is used to guide the cylinder, and the cylinder has a tendency to move downward under the elastic force of the spring. In other words, under the elastic force of the spring, the cylinder has a tendency to abut against the upper part of the conveyor chain, and at the same time, the pressure plate is at the highest point in the initial state.

[0024] In the above-mentioned continuous riveting die assembly, the lower part of the pressure plate is fixedly connected with connecting plate 1 and connecting plate 2, and the above-mentioned pressure plate, connecting plate 1 and connecting plate 2 are overlapped and fixedly connected from top to bottom, and the upper end of the connecting rod has a protruding stop edge, and the above-mentioned connecting rod is passed through the connecting plate 2 and the stop edge is tightly pressed between the connecting plate 1 and the connecting plate 2, and the lower part of the connecting plate 2 has a recessed spring seat, and the above-mentioned spring is embedded in the spring seat and the two ends of the spring act on the connecting plate 2 and the cylinder respectively.

[0025] Connecting plate one and connecting plate two are used to position the retaining edge to ensure that the connecting rod is stably connected to the pressure plate. Connecting plate two provides sufficient space for spring setting. Therefore, in the case of limited space, connecting plate one and connecting plate two can not only position the connecting rod, but also provide sufficient space for spring setting.

[0026] In the above-mentioned continuous riveting die assembly, the support frame includes a plate-shaped support plate and a rod-shaped support rod, the lower end of the support rod is fixedly connected to the frame, the upper end of the support rod is fixedly connected to the support plate, and the guide rod is penetrated on the support plate.

[0027] In the above-mentioned continuous riveting die assembly, a plurality of support rods evenly distributed on the side of the guide groove along the length direction of the guide groove on the frame form a support unit. The number of the support units is two, and the two support units are symmetrically arranged on both sides of the guide groove.

[0028] The support plate is positioned below the pressure plate through the support rod. At this time, the support plate can support the pressure plate, and after the guide rod is passed through the support plate, the up and down movement of the pressure plate can also be guided to ensure stable up and down movement of the pressure plate.

[0029] At the same time, the arrangement of the two support units can enable the support plate to be stably located under the pressure plate.

[0030] Compared with the prior art, the continuous riveting die assembly can carry out multiple riveting operations at one time because the pressing plate can drive all riveting columns to move downward under the action of external force, thereby effectively improving the operating efficiency of the entire die assembly.

[0031] At the same time, the conveyor chain can stably translate under the action of the guide groove and the support part, and the traction mechanism can also stably drive the conveyor chain to move intermittently. Therefore, the entire mold assembly not only has a high degree of automation, but also has a relatively high operating efficiency. At the same time, the entire assembly has a compact structure and has a high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] A plurality of rollers are evenly arranged in the guide cavity 1b of the frame 1 along the moving direction of the conveying chain. The plurality of rollers form a sliding support unit, and the conveying chain abuts against the sliding support unit.

[0042] The number of the sliding support units is two and the two sliding support units are respectively arranged at both sides of the guide cavity, and the two sides of the conveying chain are respectively overlapped at the corresponding sliding support units.
