Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connector processing, in particular to a wire spring forming device. Background Art
[0002] The plug-in component wire spring structure used in the connector is as Figure 5 shown in the figure. It consists of multiple copper rods 10, with concave structures bent inward on the copper rods 10. One end of the copper rod 10 is provided with an end ring 1, and the other end of the copper rod 10 is provided with an end cap 12. When the pin is inserted, the concave structure in the middle of this wire spring structure will deform, and at the same time, it can ensure that the copper rod 10 is closely attached to the outer periphery of the pin. Due to its excellent electrical connection effect and pin fixing effect, it has a wide range of application scenarios in connectors. Currently, when forming the copper rod 10, it is directly formed by automated equipment, and after the forming is completed, the welding operations of the end cap 12 and the end ring 1 are carried out. However, this method requires fine adjustment of the posture of the copper rod 10 during welding, so the efficiency is low, and there is always a problem that the posture of the copper rod 10 after welding does not meet the standard. Summary of the Utility Model
[0003] The utility model provides a wire spring forming device to solve the above-mentioned deficiencies of the prior art, facilitate the forming of the wire spring structure, and improve the forming efficiency of the copper rod in the wire spring structure, with strong practicability.
[0004] In order to achieve the purpose of the utility model, the following technologies are proposed:
[0005] A wire spring forming device includes a bottom plate, on which a pair of side plates are installed. A pair of transverse holes are opened at the upper ends of the side plates. A first end plate is installed between the bottom plates, and a first end post is installed on the first end plate. The other end of the first end post is provided with a second end post. An arc surface is formed between the inner ends of the first end post and the second end post, and the arc surface is recessed inward. When the copper rod is deformed, the set arc surface serves as a support during stamping deformation. In order to facilitate the removal of the formed wire spring structure from the first end post and the second end post, the first end post and the second end post are detachably arranged. The outer end of the second end post is installed with a movable plate, and guide rails are provided at both ends of the movable plate. The guide rails are arranged on the side plates. A pair of mounting end plates are installed between the side plates, and a middle ring is provided on the mounting end plates. A plurality of partition plates are arranged in a circumferential array between the middle rings. An inner push pressing plate is inserted between two adjacent partition plates. A conical surface is formed at one end of the outer wall of the inner push pressing plate, and a limiting outer plate is provided at the other end of the outer wall of the inner push pressing plate. A pair of guide rods are inserted through the limiting outer plate, and the inner ends of the guide rods are arranged on the partition plates. Springs are sleeved on the inner ends of the guide rods, and the springs are located inside the limiting outer plate. An arc convex surface is formed on the inner wall of the inner push pressing plate. A cylinder is installed on the bottom plate, and a movable ring is installed at the movable end of the cylinder. A pair of guiding through rods are respectively provided at both ends of the movable ring. The guiding through rods pass through the transverse holes, and a limiting nut is provided at the outer end of the guiding through rod. The limiting nut is located outside the side plate. The inner circumference of the movable ring is tangent to the conical surface of the inner push pressing plate. When stamping and forming, the movable ring is driven by the cylinder to move, and as the movable ring moves, the inner end of the inner push pressing plate will act on the copper rod, so that the copper rod can be quickly stamped and formed by the inner push pressing plate at the same time, thereby improving the efficiency of stamping and forming.
[0006] Further, limiting end plates are respectively provided at both ends of the first end post and the second end post. The limiting end plates play a role in limiting the end ring and the end cap, so as to quickly realize the stamping deformation operation of the copper rod.
[0007] Further, an insertion rod is provided at the inner end of the second end post. The insertion rod passes through the inner end of the first end post. The set insertion rod is used to improve the connection effect between the second end post and the first end post.
[0008] Further, a rotating convex block is provided at one end of the side plate. A rotating plate is rotatably provided at the outer end of the rotating convex block. The rotating plate acts on the outside of the movable plate for limiting the movable plate. A stop block is provided on the side plate for limiting the rotation of the rotating plate. The set rotating plate is used to limit the movable plate, so as to prevent the first end post and the second end post from separating during stamping deformation, which affects the stamping deformation effect of the copper rod.
[0009] Further, the inner circumference of the movable ring is a conical arc surface, so that the inner push pressing plate can move inward quickly and perform deformation operations.
[0010] The advantages of the above technical solutions are as follows:

A limiting outer plate 45 is provided at the other end of the outer wall of the inner pushing pressure plate 42. A pair of guide rods 47 are inserted through the limiting outer plate 45. The inner ends of the guide rods 47 are arranged on the partition plates 41. A spring 46 is sleeved on the inner ends of the guide rods 47. The spring 46 is located inside the limiting outer plate 45. An arc convex surface 43 is formed on the inner wall of the inner pushing pressure plate 42.
[0022] A cylinder 51 is installed on the bottom plate 1. A movable ring 5 is installed at the movable end of the cylinder 51.
