[0001] The utility model relates to the technical field of pressure riveting equipment, in particular to a copper piece pressure riveting device. Background Art

[0002] With the development of the electronics industry, many electronic product housings require the installation of various small copper components as electrical connectors or other functional components. Traditional installation methods often rely on heat riveting or other mechanical connection methods. However, due to uneven temperature control during the heat riveting process, the connection between the copper component and the housing can easily become loose, affecting product quality.

[0003] In recent years, with advances in automation and precision machining, pressure riveting has become increasingly popular as a method for achieving reliable connections without the need for heating. This method not only improves production efficiency but also effectively avoids problems such as material deformation caused by heating.

[0004] However, in traditional riveting devices, workers generally still need to take out the products after riveting. Since the product is located on the placement mold, the product and the placement mold are generally completely fitted together, and the pressure head for riveting is located above the placement mold, so the workers are less efficient in taking out the products. Therefore, in response to the above technical problems, this application makes improvements. Utility Model Content

[0025] The following is a combination of the appended examples of the present invention Figure 1-7 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] Example:

[0027] like Figures 1 to 5 As shown, the utility model discloses a copper riveting device, including a base 1, a pressure seat 2 is provided on the base 1, a rivet column pressure head 21 is fixedly connected to the lower side of the pressure seat 2, and a telescopic cylinder or other device capable of driving the pressure seat 2 to move downward can be provided above the pressure seat 2. This is common knowledge of those skilled in the art, so it will not be described here. A shell placement mold 3 is provided on the base 1 to slide back and forth, and a control mechanism for controlling the shell placement mold 3 to slide back and forth is also provided on the base 1. In addition, an ejection mechanism is provided on the shell placement mold 3, and the ejection mechanism includes an ejection head 4, which ejects upward when the shell placement mold 3 moves forward and leaves directly under the rivet column pressure head 21.

[0028] After the copper piece 8 is riveted to the shell 7 by the rivet column pressure head 21 on the pressure seat 2, the control mechanism controls the shell placement mold 3 to move forward. When the shell placement mold 3 moves forward and leaves directly under the rivet column pressure head 21, the ejection head 4 of the ejection mechanism ejects upward, thereby ejecting the riveted shell 7 upward, so that the workers can quickly take away the riveted shell 7 and improve work efficiency. Then the control mechanism moves the shell placement mold 3 backward, so that the shell placement mold 3 returns to directly under the rivet column pressure head 21. At this time, the ejection head 4 of the ejection mechanism retracts downward. While the control mechanism moves the shell placement mold 3 backward, the worker assembles the copper piece 8 onto the rivet column 71 on the shell 7. When the shell placement mold 3 returns to directly under the rivet column pressure head 21, the worker can place the shell 7 assembled with the copper piece 8 on the shell placement mold 3 to perform riveting work, and this cycle continues.

[0029] Furthermore, the base 1 is provided with an adapting notch 11 at the front side below the rivet column press head 21. When the ejecting head 4 reaches above the adapting notch 11, it is ejected upward, and when the ejecting head 4 enters the base 1 below the rivet column press head 21, it retracts downward.

[0030] Specifically, such as Figure 7 As shown, the ejection mechanism includes a lower counterweight rod 41, an intermediate connecting rod 42 and an upper connecting rod 43. A control inner cavity 31 with an opening facing downward is opened in the shell placement mold 3. The middle part of the lower counterweight rod 41 is rotatably connected to the shell placement mold 3. The lower end of the intermediate connecting rod 42 is rotatably connected to the upper end of the lower counterweight rod 41. The lower end of the upper connecting rod 43 is rotatably connected to the upper end of the intermediate connecting rod 42. A sliding opening 32 for the upper connecting rod 43 to slide up and down is opened on the shell placement mold 3, and the ejection head 4 is fixedly connected to the upper end of the upper connecting rod 43, wherein a counterweight block 44 is integrally formed on the lower side of the lower counterweight rod 41.

[0031] When the lower counterweight rod 41 reaches the adaptation notch 11, the counterweight block 44 on the lower counterweight rod 41 falls downward, thereby driving the lower counterweight rod 41 to rotate, and then driving the middle connecting rod 42 to rotate and move upward, thereby pushing the upper connecting rod 43 to move upward on the sliding opening 32, thereby pushing the ejector head 4 to move upward, and when the shell placement mold 3 returns to the base 1 directly below the rivet column press head 21, the lower counterweight rod 41 enters the base 1 under the influence of the base 1, thereby driving the ejector head 4 to retract downward.

[0032] Furthermore, two ejection heads 4 are provided, so that the shell 7 can be ejected upward more smoothly.

[0033] In addition, a rubber head 45 is fixedly connected to the upper end of the ejector head 4. The provision of the rubber head 45 can prevent the shell 7 from being worn.

[0034] In the present invention, the position where the lower counterweight rod 41 is rotatably connected to the shell placement mold 3 is located directly below the upper connecting rod 43, so that the upper connecting rod 43 can be pushed upward over a longer distance.

[0035] In the present invention, the control mechanism includes a cylinder 5, which is fixedly connected to a fixed seat 51. The fixed seat 51 is fixedly connected to the rear side of the shell placement mold 3 through a screw. The base 1 is provided with guide grooves 12 on both sides of the adaptation notch 11. A slider 33 is fixed on the lower side of the shell placement mold 3 and slides in the guide groove 12. The cylinder 5 can be used to well control the shell placement mold 3 to move back and forth on the guide groove 12.

[0036] In the present invention, a guide column 61 is fixedly connected to the base 1, and the pressure seat 2 is arranged on the guide column 61 to be movable up and down. The upper end of the guide column 61 is fixedly connected to a limit plate 62 located on the upper side of the pressure seat 2. A compression spring 63 located between the base 1 and the pressure seat 2 is sleeved on the guide column 61. The compression spring 63 is compressed when the pressure seat 2 is pressed down. After the riveting is completed, the compression spring 63 drives the pressure seat 2 to reset upward.

[0037] like Figure 4 and Figure 5 As shown in FIG. 1 , the housing 7 and the copper piece 8 are subjected to press riveting processing in the present invention. The housing 7 has a rivet stud 71, and the copper piece 8 has a through-hole 81 for inserting the rivet stud 71. During assembly, the through-hole 81 of the copper piece 8 is aligned with the rivet stud 71, so that the rivet stud 71 is inserted. Then, the housing 7 assembled with the copper piece 8 is prevented from being placed on the housing mold 3, as shown in FIG. Figure 2 and Figure 3 It should also be noted that the shell placement mold 3 can be modified in shape according to the specific shell 7 to be prevented, and the shape of the rivet column pressing head 21 is set according to the position of the rivet column 71.

[0038] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
