DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0021] Reference Figure 1 - Figure 7A forming device for an electric contact element comprises a support frame, a driving member is fixedly installed on the upper part of the support frame, an output end of the driving member passes through the lower part of the support frame and is fixedly connected to an upper forming plate 5, the upper forming plate 5 is driven by the driving member to cooperate with the support frame to perform a pressing and forming action, wherein an opening for placing a substrate is arranged at the front part of the support frame, a door panel 7 is slidably installed at the opening of the support frame, and when the upper forming plate 5 is lifted or lowered, the door panel 7 is driven to open and close at a variable speed through a transmission assembly 6.

[0022] The above-mentioned forming device of an electric contact element is initially in a standby state, and the door panel 7 is in an open state, exposing the opening at the front of the support frame, so that the operator can place the metal substrate in a predetermined position. At this time, the upper forming plate 5 is in the highest position, leaving enough space between the upper forming plate 5 and the lower forming plate 1. After the operator places the substrate in place, the driving member is started, and the driving member drives the upper forming plate 5 fixed at its output end to descend together. During the descent of the upper forming plate 5, the two door panels 7 at the opening of the support frame are driven to start closing through the transmission assembly 6. When the upper forming plate 5 is about to contact the substrate, the door panel 7 is completely closed, thereby relatively closing the placement area to prevent foreign matter from being forged together with the substrate during the forging process. Furthermore, it can also prevent the operator's fingers or other parts of the body from entering the pressing area.

[0023] After the door panel 7 is completely closed, the upper forming plate 5 continues to descend and cooperates with the lower forming plate 1 to apply pressure to the substrate to complete the press forming process of the metal substrate. In this process, the upper and lower forming plates 1 are precisely aligned to ensure the accuracy and quality of the formed components. After the pressing is completed, the driving member stops descending and moves in the opposite direction to drive the upper forming plate 5 to rise. At the same time, the door panel 7 is opened through the transmission assembly 6 to expose the formed electrical contact elements and placement area. The operator can take out the finished product to prepare for the next pressing.

[0024] In order to further ensure the safety of the operator, pressure switches are optionally integrated on both sides of the door panel 7. If the operator's hand or other foreign objects are accidentally left in the placement area during the closing process of the door panel 7, the pressure switch will be triggered. The triggered signal will immediately stop the movement of the drive component and send out an alarm signal to prompt the operator to pay attention, thereby avoiding injury. At the same time, the reset signal will be activated to drive the upper molding plate 5 back to the initial position and the door panel 7 will be reopened, thus forming a double safety protection, a mechanically linked door panel 7 closing and a safety protection mechanism of the pressure switch.

[0025] The entire process realizes a fully automated process of substrate placement, press molding, and 7-linked opening and closing of door panels, which not only improves production efficiency but also greatly reduces the risk of operators. Through ingenious transmission mechanism and safety protection design, the device realizes safe and efficient molding of electrical contact elements.

[0026] In this embodiment, in order to achieve the guiding cooperation of the upper forming plate 5 in the support frame, preferably, the support frame includes a lower forming plate 1, and the upper parts of the four corners of the lower forming plate 1 are respectively fixedly connected with support columns 2, and the upper parts of the four support columns 2 are fixedly connected with the same support plate 3. In order to achieve the driving of the upper forming plate 5 and the press forming of the electric contact elements, further, the driving part includes an electric push rod 4, and the electric push rod 4 is fixedly installed on the upper part of the support plate 3. The upper forming plate 5 includes a docking plate 504, and the docking plate 504 is fixed at the lower part of the electric push rod 4. A pressing plate 503 for press forming of the electric contact elements is fixedly installed at the lower part of the docking plate 504. In order to achieve the lifting and lowering guidance of the pressing plate 503, further, the pressing plate 503 is fixedly connected to the outside with a lifting plate 501, and the four corners of the lifting plate 501 are respectively fixedly connected with lifting blocks 502, and the lifting blocks 502 are slidably connected to the support column 2.

[0027] First of all, the core of the support frame is composed of the lower forming plate 1, the support column 2 and the support plate 3. The lower forming plate 1 serves as the base of the entire device and provides stable support for the subsequent pressing process. The four support columns 2 are vertically fixed at the four corners of the lower forming plate 1 to form a stable frame structure. These support columns 2 not only support the upper support plate 3, but also bear the important task of providing guidance for the upper forming plate 5. The support plate 3 is fixed on the top of the four support columns 2 to form an integral platform for installing the driving part, that is, the electric push rod 4. This frame structure is not only stable, but also provides precise operating space for subsequent moving parts.

[0028] The electric push rod 4 is firmly installed on the upper part of the support plate 3. The output end of the electric push rod 4 is connected to a docking plate 504. The lower part of the docking plate 504 is fixed with a pressing plate 503, which is a component that directly contacts the metal substrate and performs press forming. When the electric push rod 4 is working, it will push the docking plate 504 and the pressing plate 503 to move up and down together to achieve the pressing of the metal substrate.

[0029] In order to ensure that the pressure plate 503 maintains precise guidance when moving up and down and prevent it from shaking or shifting, a lifting plate 501 is fixedly connected to the outside of the pressure plate 503, and the four corners of the lifting plate 501 are respectively fixedly connected to the lifting blocks 502. These lifting blocks 502 form a sliding connection with the support column 2, which means that the lifting blocks 502 can slide up and down smoothly on the support column 2.

[0030] During the entire working process, the thrust of the electric push rod 4 is transmitted to the pressing plate 503 through the docking plate 504, and the sliding cooperation between the lifting block 502 and the support column 2 ensures that the pressing plate 503 always moves on the predetermined track. This structure can not only effectively control the movement trajectory of the pressing plate 503, but also provide a guarantee for high-precision pressing and forming. The sliding of the lifting block 502 on the support column 2 also absorbs part of the vibration from the pressing plate 503, making the entire pressing process smoother and extending the service life of the device.

[0031] In order to realize the cooperation between the lower forming plate 1 and the upper forming plate 5 to press the electric contact element, further, the lower forming plate 1 includes a base plate 101, a slide plate 102 is slidably installed inside the base plate 101, and two slide plates 102 are provided. The slide plate 102 includes a plate body 1021, and a groove 1022 is opened on the upper part of the plate body 1021. The grooves 1022 of the two plate bodies 1021 cooperate with the upper forming plate 5 to form a pressing cavity. In order to realize the opening and closing of the plate body 1021 for pressing and blanking, further, each slide plate 102 is fixedly connected with a slider 105 on both sides, and a screw rod 104 is screwed on one side of the base plate 101. The two opposing threads of the screw rod 104 are screwed on the sliders 105 on one side of the two slide plates 102, respectively. The lower part of the plate body 1021 is fixedly connected with a base 8, and the screw rod 104 is screwed on the two opposite threads of the screw rod 104. When the rod 104 rotates, the two slides 102 are controlled to open. In order to realize integrated pressing, unloading, ejection and door opening and closing actions, further, the transmission assembly 6 includes a single-layer rotating wheel 601, and the single-layer rotating wheel 601 is rotatably installed on the upper part of the support plate 3. The single-layer rotating wheel 601 is connected to the double-layer rotating wheel 603 through the first transmission belt 602. The first transmission belt 602 is fixedly connected to the linkage block 505 on the outside. One of the support columns 2 is provided with a through slide groove, and one of the lifting blocks 502 passes through the slide groove and is fixedly connected to the linkage block 505. The double-layer rotating wheel 603 is connected to the small rotating wheel 605 through the second transmission belt 604. The small rotating wheel 605 is fixedly connected to a spring-type limit bearing inside, and the inner ring of the spring-type limit bearing is fixed to the outside of one side of the screw rod 104.

[0032] The lower forming plate 1 is composed of a base plate 101, two slide plates 102 and a mechanism for driving the slide plates 102 to open and close. The base plate 101 is the bearing structure of the entire lower forming plate 1 and is provided with a guide rail inside. The two slide plates 102 can slide relatively along the guide rail. Each slide plate 102 includes a plate body 1021, and a groove 1022 is provided on the upper part of the plate body 1021. When the slide plates 102 are closed, the two grooves 1022 form a precise pressing cavity together with the pressing plate 503 of the upper forming plate 5 for accommodating and forming the metal substrate.

[0033] In order to realize the opening and closing of the slide plate 102, sliders 105 are fixedly connected on both sides of each slide plate 102, and these sliders 105 are connected to the screw rod 104 on the base plate 101. The screw rod 104 is a key component for driving the slide plate 102 to move. Its two ends have opposite thread directions, which are respectively engaged with the sliders 105 of the two slide plates 102. When the screw rod 104 rotates, due to the opposite thread directions, the two slide plates 102 will move toward the center or to both sides at the same time, thereby realizing the closing or opening of the pressing cavity. The bottom of the slide plate 102 is also fixedly connected to the base 8 to provide additional support, which also provides conditions for subsequent ejection and unloading.

[0034] The single-layer rotating wheel 601 is installed on the upper part of the support plate 3 and is connected to the double-layer rotating wheel 603 through the first transmission belt 602. The first transmission belt 602 is fixedly connected with a linkage block 505, which is connected to the lifting block 502 through the slide groove on the support column 2. This means that when the upper forming plate 5 moves downward, it can directly drive the double-layer rotating wheel 603 to rotate synchronously.

[0035] The double-layer rotating wheel 603 is connected to the small rotating wheel 605 through the second transmission belt 604. A spring-type limit bearing is fixedly connected inside the small rotating wheel 605. The inner ring of the bearing is connected to one end of the screw rod 104. When the double-layer rotating wheel 603 rotates, the small rotating wheel 605 is driven to rotate through the second transmission belt 604, and then the screw rod 104 is driven to rotate, thereby realizing the opening and closing of the two slides 102.

[0036] Pressing preparation stage: when the upper forming plate 5 starts to move downward, the single-layer rotating wheel 601 drives the first transmission belt 602 to move, and the linkage block 505 pushes a lifting block 502 to move along the slide groove. Since the descent of the upper forming plate 5 also drives the closing of the door panel 7, at this time, through the action of the linkage block 505, the lifting block 502 can be linked to control the door panel 7 to close in advance, so as to achieve closing the door first and then pressing.

[0037] Pressing stage: When the slide plate 102 is completely closed and the pressing cavity is formed, the spring-type limit bearing plays an important role. At this time, even if the double-layer rotating wheel 603 continues to rotate, it will not prevent the upper forming plate 5 from continuing to press down, thereby completing the pressing of the metal substrate. The introduction of the spring-type limit bearing realizes the decoupling of the closing of the slide plate 102 and the pressing action, ensuring the stability and accuracy of the pressing process.

[0038] Unloading and resetting stage: After the pressing is completed, the upper forming plate 5 rises, and the linkage mechanism moves in the reverse direction, driving the screw rod 104 to rotate in the reverse direction. At this time, the spring-type limit bearing no longer idles, but transmits the rotation to the screw rod 104, and the two slide plates 102 begin to open to both sides.

[0039] In order to realize the synchronous opening of the door panels 7, further, a sliding rod 106 is fixedly connected to the other side of the base plate 101, and the sliding rod 106 is slidably connected to the sliding blocks 105 on the other sides of the two slides 102 respectively. Two door panels 7 are provided, and one of the sliding blocks 105 of each slide plate 102 is fixedly connected to the door panel 7. The two door panels 7 are driven by the screw rod 104 to perform opening and closing actions. In order to realize the automatic ejection and unloading of the electric contact elements, further, a guide groove 1023 is also provided inside the plate body 1021, and a limiting plate 103 is fixedly connected to one side of the base plate 101. The limiting plate 103 includes a support rod 1031, and a guide rod 1032 is fixedly connected to the inner side of the support rod 1031. A guide plate 1033 is fixedly connected to one end of the guide rod 1032, and the guide plate 1033 is movably plugged into the guide groove 1023.

[0040] First, a slide bar 106 is fixed on the other side of the base plate 101, and the slide bar 106 is slidably connected to the slider 105 on the other side of the slide plate 102 to ensure the stability of the movement of the slide plate 102. The two door panels 7 are respectively fixed to the sliders 105 of the corresponding slide plates 102. When the screw rod 104 drives the slide plate 102 to open and close, the door panels 7 are also opened and closed synchronously. Secondly, in order to realize automatic unloading, a guide groove 1023 is provided inside the plate body 1021 of each slide plate 102, and a limit plate 103 is fixed on one side of the base plate 101. The limit plate 103 is connected to the guide plate 1033 through a support rod 1031 and a guide rod 1032. The guide plate 1033 is movably plugged into the guide groove 1023. When the slide plate 102 is opened, the chamfer in the guide groove 1023 will prompt the guide plate 1033 to be ejected, and the pressed electrical contact element is ejected from the groove 1022 to realize automatic unloading.

[0041] A method for forming an electric contact element comprises the following steps: Step 1: drive the electric push rod 4 to control the upper forming plate 5 to move to the upper part of the support frame; Step 2: placing the substrate in the placement area of ​​the support frame; Step 3: The electric push rod 4 controls the upper forming plate 5 to move downward. When the upper forming plate 5 moves downward to the middle, the transmission assembly 6 is used to change the speed of the transmission to control the two door panels 7 to close. The upper forming plate 5 continues to move downward to press the forming electric contact element with the substrate. Step 4: The electric push rod 4 controls the upper molding plate 5 to reset, and the two door panels 7 open.

[0042] In the present invention, the machine is initially in a standby state, and the door panel 7 is in an open state, exposing the opening at the front of the support frame, so that the operator can place the metal substrate in a predetermined position. At this time, the upper forming plate 5 is at the highest position, leaving enough space between the upper forming plate 5 and the lower forming plate 1. When the operator places the substrate in place, the driver starts the driving member, and the driving member drives the upper forming plate 5 fixed at its output end to descend together. During the descent of the upper forming plate 5, the two door panels 7 at the opening of the support frame are driven to start closing through the transmission assembly 6, so that when the upper forming plate 5 is about to contact the substrate, the door panel 7 is completely closed, thereby relatively closing the placement area to prevent the operator's fingers or other parts of the body from entering the pressing area. After the door panel 7 is completely closed, the upper forming plate 5 continues to descend, cooperates with the lower forming plate 1, applies pressure to the substrate, and completes the pressing process of the metal substrate. In this process, the upper and lower forming plates 1 are precisely matched to ensure the accuracy and quality of the forming element. After the pressing is completed, the driving member stops descending, and the driving member moves in the opposite direction to drive the upper forming plate 5 to rise. At the same time, the door panel 7 is opened through the transmission assembly 6 to expose the formed electrical contact element and the placement area. The operator can take out the finished product and prepare it for the next pressing.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
