Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to a fan-shaped strip adjustment device for a terminal stamping die of a connector. Background Technology

[0002] A connector is a device that connects two active devices and is used to transmit current or signals. The main application areas for electrical connectors include transportation, communication, networking, IT, medical, and home appliances. The rapid development of product technology and the rapid growth of the market in these application areas have strongly driven the development of connector technology. To date, connectors have evolved into a series of specialized products with a complete range of types and specifications, diverse structures, specialized focuses, distinct industry characteristics, and standardized systems. Existing connectors consist of a housing and multiple terminals housed within the housing. In the connector manufacturing process, most connector terminals are formed by stamping using die-cutting.

[0003] On continuous stamping production lines, the strip material frequently undergoes outward or inward arc-shaped bending, and this bending deformation is a critical issue affecting terminal forming. Existing fan-shaped strip adjustment structures for terminal stamping dies use raised points on the reverse side of the arc to cause material expansion and generate reverse stress, thereby straightening the strip. However, this fan-shaped strip adjustment device cannot adjust outward and inward bending strips simultaneously; two separate fan-shaped strip adjustment devices are required, significantly increasing production costs and greatly impacting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a fan-shaped strip adjustment device for terminal stamping dies of connectors, which can simultaneously adjust strips that are bent outward and inward, thereby improving production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fan-shaped strip adjustment device for a terminal stamping die includes a lower die base plate, a lower die support plate disposed on the lower die base plate, a lower template disposed on the lower die support plate, an upper die base plate, an upper die support plate and an upper template disposed on the upper die support plate, and an adjustment mechanism. The adjustment mechanism includes two fan-shaped dotting components slidably disposed side by side on the lower template, a dotting adjustment component slidably disposed on the upper template, and a push rod slidably disposed on the lower die support plate. A dotting adjustment space is formed between the dotting adjustment component and the two fan-shaped dotting components. Two sets of reset components are disposed between the lower template and the two fan-shaped dotting components. The push rod is respectively provided with a first driving inclined surface and a second driving inclined surface that abut against the two fan-shaped dotting components. The inclination directions of the first driving inclined surface and the second driving inclined surface are opposite.

[0006] In some embodiments, the reset assembly includes a slider and a spring that are linked and cooperate with the fan-shaped dotting component, and a limiting plate disposed on the lower template, wherein the two ends of the spring respectively abut against the limiting plate and the slider.

[0007] In some embodiments, the slider is provided with a positioning hole for accommodating a spring, a positioning piece is provided in the positioning hole, one end of the spring abuts against the positioning piece, and the other end of the spring extends out of the positioning hole and abuts against a limiting plate.

[0008] In some embodiments, the fan-shaped dotting component is provided with a snap-fit ​​groove, and the slider is provided with a snap-fit ​​protrusion that engages in the snap-fit ​​groove.

[0009] In some embodiments, the limiting plate is provided with screws, which pass through the limiting plate and are connected to the lower template.

[0010] In some embodiments, the two fan-shaped dotting components are respectively provided with a first abutting slope and a second abutting slope that adhere to the first driving slope and the second driving slope, respectively, and the inclination directions of the first abutting slope and the second abutting slope are opposite.

[0011] In some embodiments, the push rod is provided with two guide ramps that are transitionally connected to the first driving ramp and the second driving ramp.

[0012] In some embodiments, the push rod has a drive portion extending outside the lower die plate, and a push plate is mounted on the drive portion.

[0013] In some embodiments, the dotting adjustment member has dotting protrusions that cooperate with two fan-shaped dotting members, and a clearance groove is provided on one side of the dotting adjustment member corresponding to the dotting protrusions.

[0014] The beneficial effects of this utility model are as follows: the push rod drives two fan-shaped dotting components through the first and second driving inclined surfaces with opposite inclination directions. The two fan-shaped dotting components slide relative to each other as the push rod is pushed in and pulled out, thereby enabling the two fan-shaped dotting components to simultaneously adjust the material strip that is bent outward and inward, which helps to reduce costs and improve production efficiency.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-3As shown, a fan-shaped strip adjustment device for a terminal stamping die includes a lower die base plate 1, a lower die support plate 2 disposed on the lower die base plate 1, a lower template 3 disposed on the lower die support plate 2, an upper die base plate 4, an upper die support plate 5 disposed on the upper die base plate 4, an upper template 6 disposed on the upper die support plate 5, and an adjustment mechanism 7. The adjustment mechanism 7 includes two fan-shaped dotting elements 71 slidably disposed side by side on the lower template 3, a dotting adjustment element 72 disposed on the upper template 6, and a push rod 73 slidably disposed on the lower die support plate 2. A dotting adjustment space 700 is formed between the dotting adjustment element 72 and the two fan-shaped dotting elements 71. Two sets of reset components 74 are disposed between the lower template 3 and the two fan-shaped dotting elements 71. The push rod 73 is respectively provided with a first driving inclined surface 731 and a second driving inclined surface 732 that abut against the two fan-shaped dotting elements 71. The inclination directions of the first driving inclined surface 731 and the second driving inclined surface 732 are opposite.

[0021] like Figure 2 , 4 As shown in Figure 5, the reset assembly 74 includes a slider 741 and a spring 742 that are linked and cooperate with the fan-shaped marking element 71, and a limiting plate 743 disposed on the lower template 3. The two ends of the spring 742 abut against the limiting plate 743 and the slider 741, respectively. The reset assembly resets the two fan-shaped marking elements, ensuring that they can reliably slide relative to each other within the lower template, thus improving the reliability of the fan-shaped strip adjustment device. The slider 741 has a positioning hole 7411 for accommodating the spring 742. A positioning piece 744 is disposed within the positioning hole 7411. One end of the spring 742 abuts against the positioning piece 744, and the other end extends outside the positioning hole 7411 and abuts against the limiting plate 743. The spring engages within the positioning hole of the slider, facilitating the assembly of the spring with the slider and the limiting plate, making assembly more convenient. The fan-shaped marking component 71 is provided with a snap-fit ​​groove 711, and the slider 741 is provided with a snap-fit ​​protrusion 7412 that engages within the snap-fit ​​groove 711. The slider and the fan-shaped marking component are assembled using a snap-fit ​​engagement method, which facilitates the assembly of the fan-shaped marking component and the slider. The limiting plate 743 is provided with a screw 745, which passes through the limiting plate 743 and is connected to the lower template 3. The limiting plate is connected to the upper template by the screw, which facilitates the assembly of the reset component with the upper template and improves assembly efficiency.

[0022] like Figure 2-4As shown, the two fan-shaped marking components 71 are respectively provided with a first abutting inclined surface 712 and a second abutting inclined surface 713 that abut against the first driving inclined surface 731 and the second driving inclined surface 732, respectively. The inclination directions of the first abutting inclined surface 712 and the second abutting inclined surface 713 are opposite. The two fan-shaped marking components abut against the first driving inclined surface and the second driving inclined surface through the first abutting inclined surface and the second abutting inclined surface, respectively, thereby ensuring more reliable transmission between the two fan-shaped marking components and the push rod. The inclination directions of the first abutting inclined surface and the second abutting inclined surface are opposite, thereby enabling the two fan-shaped marking components to slide relative to each other. The two fan-shaped marking components straighten and adjust the material strip that is bent outward and inward. The push rod 73 is provided with two guide inclined surfaces 733 that are transitionally connected to the first driving inclined surface 731 and the second driving inclined surface 732. The guide inclined surfaces can play a guiding role, ensuring that the push rod can reliably perform the pushing and pulling actions, thereby improving the working reliability of the fan-shaped material strip adjustment device. The push rod 73 has a drive portion 734 extending outside the lower die plate 2, and a push plate 75 is mounted on the drive portion 734. The push rod is connected to the push plate via the drive portion, and the stamping part drives the push rod to perform an advancing or pulling action via the push plate, thereby realizing the automatic adjustment of the fan-shaped strip adjustment device, which helps to improve production efficiency. The dotting adjustment member 72 has dotting protrusions 721 that cooperate with the two fan-shaped dotting members 71, and a relief groove 722 is provided on one side of the dotting adjustment member 72 corresponding to the dotting protrusions 721. The dotting adjustment member cooperates with the two fan-shaped dotting members through the dotting protrusions, which can ensure that the adjustment mechanism reliably adjusts the fan-shaped strip.

[0023] The push rod drives two fan-shaped marking components through the first and second driving inclined surfaces with opposite inclination directions. The two fan-shaped marking components slide relative to each other as the push rod is pushed in and pulled out, thereby enabling the two fan-shaped marking components to simultaneously adjust the material strip that is bending outward and inward, which helps to reduce costs and improve production efficiency.
