Description

Technical Field

[0001] The utility model relates to the technical field of bending dies, in particular to a bending die for pure copper electronic components of relays. Background Art

[0002] In the hardware industry, ultra-low Z-bending is a common feature. For the bending processing of relay pure copper electronic components, specially designed bending molds are usually used to complete it. These bending molds need to be designed and manufactured according to the shape, size and bending requirements of the specific relay components to ensure the accuracy and consistency of the bending; the bending mold for relay pure copper electronic components is a tool used to bend the relay pure copper electronic components into the required shape during the processing of relay pure copper electronic components. The bending mold for relay pure copper electronic components is usually composed of an upper mold and a lower mold. Through the cooperation of the upper mold and the lower mold, the relay pure copper electronic components can be bent into the required angle and shape in a certain mold.

[0003] The utility model patent with announcement number CN210702223U discloses a bending mold for electronic components, including an upper mold plate and a lower mold plate arranged up and down, the upper mold plate and the lower mold plate have a linear freedom of vertical approach or distance, the upper mold plate and the lower mold plate contact each other to clamp the electronic components, the electronic components include a tube head and a pipeline connected to each other, the upper mold plate and the lower mold plate clamp the pipeline, the pipeline has a horizontally extending exposed section that is not in contact with the clamping mechanism, and the tube head also extends horizontally and is located on the other side of the exposed section of the clamping mechanism; the pressing mechanism includes a lower pressing block fixed on the upper mold plate and located directly above the tube head, the bottom height of the lower pressing block is lower than the lower surface height of the upper mold plate; the pushing mechanism includes an upper pushing block located directly below the exposed section, and the upper pushing block has a vertical reciprocating linear freedom; the bending mold bends the electronic components in a straight state into an L-shape or a Z-shape, which is convenient for the subsequent installation of the electronic components with the circuit board, and the overall efficiency is high.

[0004] However, the existing bending dies for pure copper electronic components of relays still have certain shortcomings: the positions of the bending components inside the concave plate used in the existing bending dies for pure copper electronic components of relays are mostly fixedly designed, so that when the workpiece is bent inside the die, its bending angle is fixed, which requires subsequent manual trimming, which is undoubtedly inconvenient to use;

[0005] Secondly, the low Z step of the bending protrusion of the existing relay pure copper electronic components bending mold has become the benchmark, with a height of only 0.4 and a parallelism requirement of 0.06 with the two side planes. There are two requirements for low Z bending, which are ultra-low and high-precision requirements. Conventional bending processes often result in uneven Z-shapes, frequent adjustments, and failure to meet dimensional requirements. At the same time, after the end is cut, the Z-shape is folded. On the one hand, due to the rebound of the material itself, a certain angle compensation is required, and the compensation amount is difficult to control, so it is necessary to increase the adjustment station to adjust. Since the product has two Z-shape bending requirements and the pins are independent, the requirements for the two Z-shapes to be synchronously parallel, plus the requirements for the two pins to be in the same plane, all affect the Z-shape and accumulate. In terms of Z-shape guarantee, the minimum dimensional accuracy needs to be 0.15, and due to the requirements for part insertion, when the tolerance is enlarged, insertion is difficult, resulting in pin offset, which cannot meet the use requirements. Neither the assembly requirements of the product nor the use requirements of the product can be met, affecting customer order requirements. In either case, customers cannot accept it.

A spring 108 is welded to the horizontal part of the support frame 107, and a locking ball 109 is welded to the other end of the spring 108. The locking ball 109 is slidably connected to the locking hole 106. A rotating disk 110 is fixedly sleeved on the outer side of the screw 102. The rotating disk 110 is in contact with the support plate 104. A limiting ring groove 111 is provided on the surface of the rotating disk 110.

By setting the limiting protrusion 112, the rotating disk 110 can be rotationally limited.

[0027] The specific implementation process of the utility model is as follows: when in use, the micro motor 101 is started to drive the output shaft to rotate, so as to drive the screw rod 102 to rotate.

Under the action of the support frame 107, the spring 108 is deformed, and finally the clamping ball 109 is separated from the clamping hole 106. Under the action of force, the clamping ball 109 moves along the surface of the support plate 104.
