Description

Technical Field

[0001] The utility model relates to the technical field of laminated busbars, and more specifically, to an edge pressing die of a riveting machine. Background Art

[0002] With the development of industry, copper plate processing is widely used in many industries. When processing copper plates, they need to be bent, electroplated and riveted so that they can be installed in the cabinet. The traditional method is to rivet first, then bend and electroplate.

[0003] For example, application publication number CN111215529A discloses a mold for a bending machine, including a lower mold, a middle mold penetrating the top of the lower mold, and the middle mold is fixedly connected to the lower mold, a workpiece fixing seat is arranged at the top of the middle mold, and the workpiece fixing seat is fixedly connected to the middle mold, and an upper mold is arranged on the upper surface of the workpiece fixing seat; the transverse bending and longitudinal bending of the original bending machine mold are integrated, and when the workpiece is transversely bent, the workpiece is placed on the workpiece fixing seat, and the upper mold is used to press down to bend the workpiece.

[0004] In the above, when the copper plate used has a compact edge pressing position and a small size, there is space limitation on the bending machine, which leads to failure of forming and makes it impossible to bend the workpiece, thereby reducing production efficiency and edge pressing accuracy and shortening the service life of the mold. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a pressing die for a riveting machine which improves the pressing accuracy and efficiency, prolongs the service life of the die and reduces the production cost.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pressing die of a riveting machine comprises an upper die, a copper plate and a lower die, the copper plate is placed between the upper die and the lower die, a through groove is provided on the copper plate, a lower pressing plate is provided on the through groove, one side of the lower pressing plate is connected to the inner wall of the through groove, a pre-buried hole is provided on the lower pressing plate, a traction plate placed below the upper die is provided on the upper die, plug-in holes are provided on the traction plate and the upper die, an arc plate is provided on the lower die, the arc plate is connected to the top of the lower die, positioning pins are provided on the arc plate and the lower die, the positioning pins on the lower die pass through the through groove and extend into the plug-in hole on the traction plate to be connected to the plug-in hole, the positioning pins on the arc plate pass through the pre-buried hole and extend into the plug-in hole on the upper die to be connected to the plug-in hole, so that the lower pressing plate is lifted up by the arc plate.

[0008] The utility model is further configured as follows: a placement slot is provided on the arc plate, and the placement slot is placed in the middle of the arc plate, so that the lower pressure plate is placed in the placement slot and connected to the placement slot.

[0009] The utility model is further configured as follows: there are three positioning pins, one of which is placed on the placement slot, and the other two positioning pins are placed on the lower mold and connected to the lower mold.

[0010] The utility model is further configured as follows: a protrusion extending inwards is provided on the top of the positioning pin.

[0011] The utility model is further configured as follows: there are three plug-in holes, one of which is placed on the upper mold, and the other two are placed on the traction plate.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are:

[0013] When the copper plate used is compactly positioned and small in size, the upper mold is placed above the copper plate and the lower mold is placed below the copper plate. The locating pin on the storage slot passes through the embedded hole and extends into the plug-in hole on the upper mold. At the same time, the other two locating pins on the lower mold pass through the through slot and extend into the plug-in hole on the traction plate. At this time, the lower pressing plate is placed in the storage slot. Because the arc plate and the traction plate both have height, the lower pressing plate is lifted up. When the mold is running on the riveting machine, the upper and lower molds are precisely matched to achieve a one-time precise pressing of the copper plate, which greatly improves the production efficiency and the qualified rate of the product, and achieves dimensional accuracy, so that the pressing processing position and size of the copper plate are more applicable, and can better meet the customer's pressing needs, thereby improving the pressing accuracy and efficiency, extending the service life of the mold, and reducing production costs.

[0019] like Figure 1 to Figure 2 As shown, the edge pressing die of the riveting machine includes an upper die 1, a copper plate 2 and a lower die 3. The copper plate 2 is placed between the upper die 1 and the lower die 3. A through groove 4 is opened on the copper plate 2. A lower pressing plate 5 is installed on the through groove 4. One side of the lower pressing plate 5 is connected to the inner wall of the through groove 4. The lower pressing plate 5 is provided with a pre-buried hole 6.

[0020] The upper mold 1 is provided with a traction plate 7 placed below the upper mold 1, and two plug-in holes 8 are provided on the traction plate 7. The upper mold 1 is provided with a plug-in hole 8. The lower mold 3 is provided with an arc plate 9, and the arc plate 9 is connected to the top of the lower mold 3. A placement slot 11 is provided on the arc plate 9, and the placement slot 11 is placed in the middle of the arc plate 9 so that the lower pressure plate 5 is placed in the placement slot 11 and contacts with the placement slot 11.

[0021] A positioning pin 10 is provided on the placement slot 11, and two positioning pins 10 are provided on the lower mold 3. The positioning pin 10 on the lower mold 3 passes through the through slot 4 and extends into the plug-in hole 8 on the traction plate 7 to contact the inner wall of the plug-in hole 8. The positioning pin 10 on the arc plate 9 passes through the embedded hole 6 and extends into the plug-in hole 8 on the upper mold 1 to contact the inner wall of the plug-in hole 8, so that the lower pressure plate 5 is lifted by the arc plate 9.

[0022] A protrusion extending inwardly is installed on the top of the positioning pin 10.

[0023] Working principle: When the copper plate 2 used has a compact edge pressing position and a small size, the upper mold 1 is placed above the copper plate 2, and the lower mold 3 is placed below the copper plate 2. The positioning pin 10 on the storage slot 11 passes through the embedded hole 6 and extends into the plug-in hole 8 on the upper mold 1. At the same time, the other two positioning pins 10 on the lower mold 3 pass through the through slot 4 and extend into the plug-in hole 8 on the traction plate 7. At this time, the lower pressure plate 5 is placed in the storage slot 11.

[0024] Because the arc plate 9 and the traction plate 7 both have a height, the lower pressing plate 5 is lifted up, and then when the mold is running on the riveting machine, the upper mold 1 and the lower mold 3 can achieve a one-time accurate edge pressing of the copper plate 2 through the precisely matched upper mold and the lower mold, which greatly improves the production efficiency and the qualified rate of the product, and achieves dimensional accuracy, so that the edge pressing processing position and size of the copper plate 2 are more applicable, and can better meet the customer's edge pressing needs, thereby improving the edge pressing accuracy and efficiency, extending the service life of the mold, and reducing production costs.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
