Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal wire processing or treatment technology, and in particular relates to a needle bending forming tool. Background Technology
[0002] Electronic components with pins are often soldered onto circuit boards. For some components, the bending position of the pins needs to be determined based on actual requirements. Therefore, these components require pin bending before being soldered onto the circuit board. Currently, pin bending presents the following problems:
[0003] 1. Manual forming results in poor quality, with errors in bending positions that are difficult to control, leading to low efficiency and poor quality.
[0004] 2. The base of the pin is a relatively vulnerable area. When bending, the base of the pin will also be affected, which will lead to damage to the base of the pin and ultimately affect the overall quality of the circuit board.
[0005] 3. Different types of electronic components require different bending positions, and existing bending machines have poor adaptability. Utility Model Content
[0006] To solve the above problems and overcome the shortcomings of the existing technology, this utility model provides a needle bending forming tool.
[0007] The purpose of this invention is to provide a needle bending forming fixture that can protect the needle root, achieve accurate and fast needle bending forming, and improve needle forming efficiency and forming quality.
[0008] To achieve the purpose of this utility model, the technical solution of this utility model is as follows:
[0009] A needle bending forming fixture includes a main support frame, which includes a lower clamping plate and an upper clamping plate above the lower clamping plate. There is a gap between the lower clamping plate and the upper clamping plate for the needle to pass through. A device stage is provided on one side of the lower clamping plate, and a placement boss is provided on the device stage. A height adjustment plate is provided on the other side of the lower clamping plate, and a pressure plate that can move towards the height adjustment plate is provided above the height adjustment plate. This utility model places the device to be processed by the placement boss on the device stage, clamps the root of the needle by the upper and lower clamping plates, determines the forming height of the needle by the height adjustment plate, and presses the pressure plate to contact the needle and bend the needle downward to form the shape.
[0010] Preferably, the main support includes two spaced-apart side plates, and a lower clamping plate is arranged in the space between the two side plates. The lower clamping plate can not only cooperate with the upper clamping plate to form a clamping structure, but also serve as a connecting structure for the side plates, thereby enhancing the structural strength of the entire tooling.
[0011] Preferably, a first track is provided on the side plate, and the side end of the upper clamping plate is arranged on the first track to ensure that the upper clamping plate can move stably and aligned with the lower clamping plate.
[0012] Preferably, the upper edge of the height adjustment plate away from the lower clamping plate is an arc-shaped transition edge, and the lower edge of the pressure plate near the lower clamping plate is an arc-shaped transition edge, which improves the bending effect of the needles and minimizes or eliminates damage during the bending process.
[0013] Preferably, the upper end of the main support is provided with an upper cover plate. The upper cover plate can prevent the upper clamping plate and pressure plate from detaching from the main support, and can also connect the side plates of the main support together to enhance the structural strength of the entire tooling.
[0014] Preferably, a connecting seat is provided on the upper clamping plate, and an upper adjusting screw is provided on the upper cover plate. The lower end of the upper adjusting screw abuts against the connecting seat. By rotating the upper adjusting screw, the upper clamping plate moves downward and is fixed by the upper adjusting screw, so that the upper clamping plate and the lower clamping plate clamp the root of the needle.
[0015] Preferably, the pressure plate is provided with protrusions.
[0016] Preferably, a second track is provided on the side plate, and the side end of the pressure plate is arranged on the second track to ensure stable movement of the pressure plate and alignment with the position where the needle needs to be bent.
[0017] Preferably, the side end of the height adjustment plate is arranged on the second track, and a lower adjustment screw is screwed onto the height adjustment plate. The screw head of the lower adjustment screw passes through the height adjustment plate and is connected to the lower clamping plate. This utility model changes the position of the needle bend by adjusting the height adjustment plate.
[0018] Preferably, a base is provided at the lower end of the main support.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. This utility model uses a main support as the load-bearing structure. The upper and lower clamping plates create a gap for the needle to pass through. The device to be processed is placed on the placement boss of the device stage, so that the needle passes through the gap between the upper and lower clamping plates. The root of the needle is restricted by the upper and lower clamping plates, protecting the root of the needle and preventing it from bending and being damaged. The height adjustment plate can be adjusted. The pressure plate moves downward and contacts the needle. The pressure plate presses down on the needle and causes the needle to bend downward, realizing accurate and fast needle bending and forming, improving the needle forming efficiency and forming quality.
[0021] 2. The upper clamping plate and the lower clamping plate of this utility model are movably connected, the device stage and the lower clamping plate are detachably connected, and the height adjustment plate and the lower clamping plate are detachably connected.

[0022] 3. This utility model uses a base as the bottom support, an "H"-shaped main bracket is installed on the base and a lower clamping plate is used as a reinforcing structure, and an upper cover plate seals the top of the main bracket. In addition to enhancing the overall strength of the tooling, it can also prevent the upper clamping plate, pressure plate and other structures from detaching from the main bracket, and can also serve as a load-bearing installation structure for the upper adjusting screw, so that the upper clamping plate can move and complete the cooperation between the upper clamping plate and the lower clamping plate.

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0044] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0045] Example 1
[0046] This embodiment is a pin bending forming fixture used to accurately and quickly bend electronic components that have not undergone bending processing. In this embodiment, the electronic components can also be referred to as the devices to be processed.
[0047] like Figures 1-18As shown, in this embodiment, the base 5 serves as the bottom support structure. The main support 2 is installed on the base 5 and is fixedly connected to the base 5 by Phillips head countersunk screws. A top cover plate 1 is installed on the upper end face of the main support 2 and is connected to the main support 2 by fixing bolts 7. The fixing bolts 7 can also be replaced by Phillips head pan screws. The main support 2 includes two spaced side plates and a lower clamping plate. The side plates are fixedly connected to the base 5 and the top cover plate 1. The lower clamping plate is arranged in the gap between the two side plates. In one embodiment, the lower clamping plate and the side plates are integrally formed. In another embodiment, the side plates have slots, and the lower clamping plate is installed in the slots of the side plates. The lower clamping plate can be replaced as needed. In another embodiment, the lower clamping plate and the side plates are connected by bolts or screws, so that the lower clamping plate is fixed to the side plates. By removing the bolts or screws, the lower clamping plate and the side plates can be detachably connected, and the lower clamping plate can also be replaced as needed.
[0048] In this embodiment, an upper clamping plate 3 is installed above the lower clamping plate, and there is a gap between the lower clamping plate and the upper clamping plate 3 for the needle to pass through. As one implementation, the upper clamping plate 3 has a connecting seat, and an upper adjusting screw 8 is installed on the upper cover plate 1. The lower end of the upper adjusting screw 8 abuts against the connecting seat. Rotating the upper adjusting screw 8 presses the connecting seat, causing the upper clamping plate 3 to move downward. The upper clamping plate 3 and the lower clamping plate clamp the root of the needle of the workpiece to be processed, preventing the root of the needle from moving and protecting the root of the needle. As another alternative, the upper adjusting screw 8 can be replaced with a fixed-stroke cylinder or electric cylinder, so that the upper clamping plate 3 can reach a distance from the upper end of the lower clamping plate. The upper clamping plate 3 can be positioned in a designated area and clamp the root of the needle. Other solutions that can move the upper clamping plate 3 can also be used. As a corresponding matching solution, the side plate has a first track, and the side end of the upper clamping plate 3 is arranged on the first track. The upper clamping plate 3 moves along the first track, thereby making the upper clamping plate 3 move stably in the height direction and better clamp the root of the needle. The first track can be a slide rail installed on the side plate. For example, the slide rail can be installed on the inner wall of the side plate, that is, the end face of the side plate facing the upper clamping plate 3. The side end of the upper clamping plate 3 is equipped with a slider that cooperates with the slide rail. The first track can also be a groove structure opened on the side plate, and the side end of the upper clamping plate 3 is placed in the groove structure of the side plate.
[0049] As a mating structure, in this embodiment, a device platform 4 is installed on one side of the lower clamping plate, and a height adjustment plate 10 is arranged on the other side of the lower clamping plate. That is, the device platform 4 and the height adjustment plate 10 are respectively arranged on both sides of the lower clamping plate, so that the device platform 4 can place the device to be processed. The pins pass through the gap between the upper clamping plate 3 and the lower clamping plate and cooperate with the height adjustment plate 10. Specifically, the device platform 4 has a placement boss. The device platform 4 is generally L-shaped. The placement boss is a horizontal plate, and a vertical plate is connected to the placement boss. The vertical plate of the device platform 4 is fixed to the lower clamping plate by bolts or screws. As one implementation scheme, multiple corresponding connecting bolt holes are reserved on the lower clamping plate. The number and position of these connecting bolt holes are determined according to the device to be processed. In use, the device to be processed is placed on the placement boss, and the unprocessed pins are basically in a horizontal state. The upper clamping plate 3 and the lower clamping plate clamp the pins to complete the fixation of the device to be processed.
[0050] As a core structure, a pressure plate 9 is located above the height adjustment plate 10 and can move towards it. The pressure plate 9 has protrusions. The upper edge of the height adjustment plate 10, away from the lower clamping plate, is an arc-shaped transition edge. The lower edge of the pressure plate 9, near the lower clamping plate, is also an arc-shaped transition edge. Pressing the protrusions on the pressure plate 9 causes it to descend. The lower end of the pressure plate 9 contacts the needle, causing the needle to bend at the arc-shaped transition edge. The bend in the needle also forms an arc shape under the action of the arc-shaped transition edge, resulting in a better bending effect and reducing... To mitigate damage from bending of small needles, as a fixing method, the side end of the height adjustment plate 10 is arranged on the second track. A lower adjustment screw 6 is screwed onto the height adjustment plate 10. The screw head of the lower adjustment screw 6 passes through the height adjustment plate 10 and connects to the lower clamping plate, thereby fixing the height adjustment plate 10 to the lower clamping plate. As another fixing method, multiple bolt holes are pre-drilled on the lower clamping plate. By engaging screws with the bolt holes at corresponding positions and heights, the height adjustment plate 10 is installed at the corresponding height. Alternatively, different thicknesses can be selected. The height adjustment plate 10 serves as a solution for the stable movement of the pressure plate 9. In this embodiment, a second track can be arranged on the side plate, which operates on the same principle as the first track. The second track can be formed by creating a groove on the side plate, with the side end of the pressure plate 9 positioned on the second track. Alternatively, the second track can be formed by installing a slide rail. A slider that mates with the second track is installed on the side end of the pressure plate 9. As a conceivable mating solution, a return spring is arranged below the pressure plate 9. When the pressure plate 9 is pressed down and the pins are bent, the pressure plate 9 is released, and the pressure plate 9 automatically returns to its original position under the action of the return spring. Specifically, two parallel auxiliary rods can be installed on the base 5, and a through hole is created on the pressure plate 9 and a linear bearing is installed thereon. The auxiliary rods pass through the linear bearing, and the return spring is positioned between the pressure plate 9 and the base 5. As a mating structure for this solution, a buffer block is installed on the upper end of the pressure plate 9 or the lower end of the upper cover plate 1. As a conceivable mating solution, a drive cylinder, such as a pneumatic cylinder or an electric cylinder, can be used to drive the pressure plate 9 to achieve reciprocating movement. This embodiment can also be applied to this solution.
[0051] In terms of material selection, the overall structure of this embodiment is made of aluminum alloy. For example, the upper cover plate 1, the main support 2, the upper clamping plate 3, the device platform 4, the base 5, the pressure plate 9, and the height adjustment plate 10 are all made of 6061 aluminum alloy, which meets the strength requirements and has a suitable weight. Through holes can be opened on the base 5 so that the tooling of this embodiment can be installed on the workbench for use.
[0052] Taking a pump laser as an example, the principle and usage steps of the tooling in this embodiment are as follows:
[0053] Adjust the position of the device stage 4 and the height adjustment plate 10 on the lower clamping plate, place the pump laser on the placement protrusion of the device stage 4, so that the pin of the pump laser is placed between the upper clamping plate 3 and the lower clamping plate, ensuring that the pin is in a horizontal state and that the pin is clamped by the upper clamping plate 3 and the lower clamping plate, thus fixing the root of the pin. Press the pressure plate 9 so that the pressure plate 9 moves downward and the bottom end of the pressure plate 9 contacts the pin, thus completing the bending operation of the pin.
[0054] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
