Description

Technical Field

[0001] This utility model relates to the field of copper bar manufacturing technology, and in particular to an improved mold for copper bar riveting rivets. Background Technology

[0002] In the manufacturing process of copper bars, the angle iron-shaped copper bar requires riveting stud one to the inner side of the horizontal section and stud two to the inner side of the vertical section. In existing technologies, copper bar riveting typically employs a step-by-step operation, requiring the riveting of two studs separately. This is not only cumbersome and inefficient, but also makes it difficult to maintain consistent positioning benchmarks during the two steps, easily leading to deviations in the relative positions of stud one and stud two, affecting product assembly accuracy. Furthermore, the lack of targeted support and buffer structures during riveting results in uneven stress on the copper bar, causing deformation, and compromising the assembly stability of the stud shank and cap, further reducing product quality. Therefore, there is an urgent need to design a copper bar riveting mold that can achieve one-step riveting, precise positioning, and reduced deformation. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an improved mold for copper bar riveting rivets, so as to solve the problems of low riveting efficiency, positioning deviation and easy deformation of copper bars.

[0004] To achieve the above and other related objectives, the technical solution provided by this utility model is: an improved mold for copper bar riveting, wherein the copper bar is configured as an angle iron structure and has a horizontal part and a vertical part, wherein a stud is riveted to the inner side of the horizontal part, and a second stud is riveted to the inner side of the vertical part, and the mold includes:

[0005] The lower mold includes a lower mold base, a fixed mold 1, a movable mold 1, and a support mold. The fixed mold 1 is disposed on the top side of the lower mold base via an elastic element 1. The movable mold 1 is slidably disposed on the top side of the lower mold base and can approach or move away from the fixed mold 1. The support mold is disposed on the top side of the lower mold base via an elastic element 2 and is located between the fixed mold 1 and the movable mold 1. The fixed mold 1 is used to support the horizontal part and the riveting stud 1. The movable mold 1 is used to support the rod part of the riveting stud 2. The support mold is used to support the vertical part.

[0006] The upper mold includes an upper mold base, a floating plate, a fixed mold two, a movable mold two, an actuator one, and an actuator two. The floating plate is disposed on the bottom side of the upper mold base via an elastic element three. The fixed mold two is fixedly disposed on the bottom side of the upper mold base and its bottom end can pass through the floating plate and is correspondingly disposed with the fixed mold one. The movable mold two is slidably disposed on the bottom side of the floating plate and is correspondingly disposed with the movable mold one. The actuator one is fixedly disposed on the bottom side of the upper mold base and its bottom end passes through the floating plate and is correspondingly disposed with the actuating end of the movable mold two, so as to actuate the movable mold two to approach the fixed mold one. The actuator two is fixedly disposed on the bottom side of the upper mold base and its bottom end passes through the floating plate and is correspondingly disposed with the actuating end of the movable mold one, so as to actuate the movable mold one to approach the fixed mold one.

[0007] The preferred technical solution is that the top side of the fixed mold is provided with a mounting hole, which is used to support the rod of the riveting stud.

[0008] A preferred technical solution is that the horizontal part of the copper bar is located on the top side of the fixed mold, and the vertical part is attached to the side of the fixed mold close to the movable mold.

[0009] The preferred technical solution is as follows: the top side of the movable mold one is provided with a mounting groove one, and the bottom side of the movable mold two is provided with a mounting groove two. The mounting groove one and the mounting groove two constitute an assembly structure that corresponds to and matches the rod part of the riveting stud two.

[0010] The preferred technical solution is as follows: the movable mold is connected to the top side of the lower mold base via a sliding reset assembly. The sliding reset assembly consists of a slide rail, a slide block, and a spring. The slide rail is fixed to the top side of the lower mold base, the slide block slides on the slide rail, and the spring is arranged along the extension direction of the slide rail. One end of the spring is fixedly connected to the slide block, and the other end is fixedly connected to the stop block at the end of the slide rail. The sliding reset assembly is configured to control the movable mold to automatically reset to a state away from the fixed mold after riveting is completed.

[0011] The preferred technical solution is that the second movable module is connected to the bottom side of the floating plate through the second sliding reset component, and the second sliding reset component has the same structure as the first sliding reset component.

[0012] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0013] Improved riveting efficiency: Through the corresponding structural design of the upper and lower dies, the two studs of the horizontal and vertical parts of the copper bar can be riveted in one mold closing operation, eliminating the need for step-by-step operations and greatly shortening the production cycle.

[0014] Reduce the risk of deformation: Elastic components one, two, and three provide buffers for the fixed mold one, the support mold, and the floating plate, respectively, reducing rigid impact during the riveting process; at the same time, the close support of the fixed mold, the support mold, and the movable mold for the copper bar ensures that the copper bar is subjected to uniform force and reduces deformation.

[0015] Ease of operation: The sliding reset component enables the movable mold to automatically reset after riveting, simplifying the material handling operation and improving the ease of use of the equipment. Attached Figure Description
