Description

Technical Field

[0001] This utility model relates to the field of terminal processing technology, specifically a terminal forming and pressing device. Background Technology

[0002] Terminal forming and pressing equipment is a widely used automated device in the electronics, electrical, and automotive wiring harness industries. It is primarily used to process, form, and press wires (electrical wires) and terminals together to form a wiring harness assembly with conductive and connecting functions. Its core function is to ensure a firm connection between the terminals and wires, good conductivity, and to meet the electrical and mechanical performance requirements of the product.

[0003] A search revealed Chinese Patent Publication No. CN 220914723U, which discloses a terminal pressing device belonging to the technical field of terminal processing equipment. The device includes a base plate with a support frame on the base plate. An electric push rod is located within the support frame, and an upper pressing block is located at the output end of the electric push rod. A fixing block is located within the support frame, and a lower pressing block is located on the fixing block. An air bladder is located within the lower pressing block, and a connecting assembly is located within the support frame. This terminal pressing device, through the arrangement of the electric push rod, upper pressing block, lower pressing block, piston cylinder, and air bladder, further avoids the possibility of misalignment between the terminal and the connecting wire during pressing, which may occur due to improper terminal positioning. Simultaneously, the contact and separation of the upper pressing block with the terminal enables rapid positioning and release of the limiting function, facilitating pressing operations for workers and ensuring pressing effect and product qualification rate.

[0004] In most of the aforementioned utility models, the lower pressure block and the fixed frame are rigidly connected by bolts, clips, etc. Disassembly and installation require additional tools such as wrenches and screwdrivers, making the operation process cumbersome. This not only prolongs the mold change time and reduces the equipment switching efficiency, but also increases the workload of operators. Therefore, there is a need to provide a pressing device that can quickly replace the lower pressure block to improve switching efficiency and production flexibility. Utility Model Content

[0005] The purpose of this utility model is to provide a terminal forming and pressing device to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a terminal forming and pressing device, comprising:

[0007] A base plate and a support frame, wherein the support frame is fixed to the middle of the upper surface of the base plate;

[0008] The assembly / disassembly component includes a fixed frame, a lower pressure block, a connecting frame, a connecting hole, and a movable column. The fixed frame is fixed to the upper surface of the support frame, the lower pressure block is installed inside the fixed frame, there are two connecting frames, which are fixed to the middle of the two sides of the fixed frame respectively, the connecting hole is opened in the middle of the connecting frame, and there are two movable columns, which slide through the corresponding connecting holes respectively.

[0009] Furthermore, an electric push rod is fixed inside the support frame, and an upper pressure block is fixed to the output end of the electric push rod.

[0010] Furthermore, the fixed frame has movable holes on both sides, and the movable holes are aligned with the connecting holes.

[0014] Furthermore, a first guide groove is provided on the outer surface of the first limiting plate, and a second spring is fixed on the other side of the inside of the limiting frame.

[0015] Furthermore, a second limiting plate is fixed to one end of the second spring, and a second guide groove is provided on the outer surface of the second limiting plate. The first guide groove and the second guide groove correspond to the upper pressure block.

[0016] This utility model has the following beneficial effects:

[0017] This invention, through its base plate, support frame, electric push rod, upper pressure block, and disassembly / assembly components, allows for easy installation and removal of the lower pressure block when pressing different terminals. Simply pull the two movable columns to the sides; the movable columns move the baffles to the sides, and under the limiting effect of the connecting frame, the mounting spring is compressed, causing the end of the movable column to move out of the slot. At this point, the lower pressure block can be removed from the fixed frame, and a different model of lower pressure block can be replaced. The new model lower pressure block is then placed into the fixed frame, and the movable columns are simultaneously pulled outwards.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this utility model is a terminal forming and pressing device, comprising:

[0030] The base plate 11 and the support frame 12 are fixed in the middle of the upper surface of the base plate 11. An electric push rod 13 is fixed inside the support frame 12, and an upper pressure block 14 is fixed at the output end of the electric push rod 13.

[0031] The base plate 11 serves as the basic load-bearing structure of the device, providing a stable installation platform for the entire equipment. The support frame 12 is used to support and fix the electric push rod 13, providing it with an installation carrier. The electric push rod 13 drives the upper pressure block 14 to move up and down through telescopic movement, providing the power required for pressing and realizing the precise pressing operation of the terminal. The upper pressure block 14 is one of the components that directly participate in the pressing. Driven by the electric push rod 13, it moves downward and cooperates with the lower pressure block 22 to press the terminal into shape, and its shape is adapted to the terminal specifications.

[0032] The assembly and disassembly components include a fixed frame 21, a lower pressure block 22, a connecting frame 24, a connecting hole 25, and a movable column 26. The fixed frame 21 is fixed to the upper surface of the support frame 12. The lower pressure block 22 is installed inside the fixed frame 21. There are two connecting frames 24, which are fixed to the middle of the two sides of the fixed frame 21 respectively. The connecting hole 25 is opened in the middle of the connecting frame 24. There are two movable columns 26, which slide through the corresponding connecting hole 25 respectively.

[0033] The fixed frame 21 limits the lower pressure block 22 through its own frame structure, ensuring that the lower pressure block 22 maintains the correct position during the pressing process. The movable hole 211 corresponds to the connecting hole 25 and the slot 23, providing a guide channel for the sliding of the movable column 26. The lower pressure block 22 corresponds to the upper pressure block 14 and is one of the key components for pressing the terminal. Its surface shape is adapted to the bottom of the terminal. During pressing, it works together with the upper pressure block 14 to press the terminal and complete the forming and pressing. The slot 23 matches the end of the movable column 26. When the movable column 26 is inserted into the slot 23, the lower pressure block 22 can be firmly fixed in the fixed frame 21, preventing the lower pressure block 22 from loosening or shifting during the pressing process. The connecting hole 25 corresponds to the movable hole 211 and the slot 23, and is the sliding channel for the movable column 26.

[0034] Movable holes 211 are provided on both sides of the fixed frame 21, and the movable holes 211 are positively aligned with the connecting holes 25. The slots 23 are provided on both sides of the lower pressure block 22, and the slots 23 are positively aligned with the connecting holes 25. A baffle 27 is fixed in the middle of the movable column 26. The baffle 27 is located inside the connecting frame 24. A mounting spring 28 is fixed on one side of the baffle 27. The mounting spring 28 is located inside the connecting frame 24, and one end of the movable column 26 extends into the slot 23.

[0035] When the movable column 26 is pulled, its end can be removed from the slot 23, thus disassembling the lower pressure block 22. After being released, under the action of the mounting spring 28, its end is inserted into the slot 23, thus fixing the lower pressure block 22. This can be done without additional tools. When the movable column 26 is pulled, the mounting spring 28 is compressed. After the movable column 26 is released, the spring returns to its original shape, causing the movable column 26 to automatically insert into the slot 23, ensuring the rapid fixing of the lower pressure block 22 and improving replacement efficiency.

[0036] Working principle:

[0037] When pressing different terminals, the lower pressure block 22 needs to be replaced. Pull the two movable columns 26 to both sides. The movable columns 26 drive the baffle 27 to move to both sides. Under the limit of the connecting frame 24, the mounting spring 28 will be compressed, so that the end of the movable column 26 moves out of the slot 23. At this time, the lower pressure block 22 can be taken out from the fixed frame 21. Replace with a lower pressure block 22 of a different model. Then put the new model lower pressure block 22 into the fixed frame 21. Simultaneously pull the movable column 26 outward. When the movable column 26 is aligned with the slot 23, under the elastic force of the mounting spring 28, the mounting spring 28 will quickly restore its deformation, drive the movable column 26 into the slot 23, and fix the lower pressure block 22 in the fixed frame 21.

[0038] This step allows for the disassembly and installation of the lower pressure block 22 by directly pulling the movable column 26, without the need for additional tools. This significantly shortens the mold change time when pressing different types of terminals, and improves the equipment's switching efficiency and production flexibility.

[0039] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The limiting component includes a limiting frame 31, a first spring 32 and a first limiting plate 33. The limiting frame 31 is fixed in the middle of the support frame 12, the first spring 32 is fixed inside one side of the limiting frame 31, and the first limiting plate 33 is fixed at one end of the first spring 32.

[0041] The limiting frame 31 restricts the movement range of the first limiting plate 33 and the second limiting plate 35 through its own structure, ensuring that they can only slide left and right within a preset range, avoiding the impact on the positioning effect of the terminal due to excessive displacement. The first spring 32 provides elastic force. When the upper pressure block 14 presses down and pushes open the first limiting plate 33, the first spring 32 is compressed and stores elastic potential energy. Before pressing and after the upper pressure block 14 is reset, the first limiting plate 33 moves towards the middle under the action of the first spring 32, cooperating with the second limiting plate 35 to clamp the terminal in the middle, ensuring that the terminal is in the center position of the lower pressure block 22.

[0042] The outer surface of the first limiting plate 33 is provided with a first guide groove 331, and the other side of the inner side of the limiting frame 31 is fixed with a second spring 34. One end of the second spring 34 is fixed with a second limiting plate 35, and the outer surface of the second limiting plate 35 is provided with a second guide groove 351. The first guide groove 331 and the second guide groove 351 correspond to the upper pressure block 14.

[0043] When the upper pressure block 14 is pressed downward, the edge of the upper pressure block 14 will contact the first guide groove 331. The inclined surface of the first guide groove 331 can guide the upper pressure block 14 to smoothly push the first limiting plate 33 to both sides, avoiding rigid collision between the upper pressure block 14 and the first limiting plate 33, and ensuring the stability of the pressing process. During the pressing process, when the second limiting plate 35 is pushed open by the upper pressure block 14, the second spring 34 is compressed. After the upper pressure block 14 is reset, the elastic force of the second spring 34 pushes the second limiting plate 35 to move towards the middle, and cooperates with the first limiting plate 33 to complete the positioning of the terminal.

[0044] Working principle:

[0045] When the electric push rod 13 extends downward and drives the upper pressure block 14 to press downward, under the guidance of the first guide groove 331 and the second guide groove 351, the upper pressure block 14 contacts the upper surfaces of the first limiting plate 33 and the second limiting plate 35, which will push the first limiting plate 33 and the second limiting plate 35 to both sides to facilitate the pressing of the terminal. When the upper pressure block 14 moves upward, under the elastic force of the first spring 32 and the second spring 34, the first limiting plate 33 and the second limiting plate 35 move synchronously towards the middle, positioning the terminal at the center of the lower pressure block 22 to facilitate the pressing accuracy.

[0046] In this step, when the upper pressure block 14 moves upward, under the elastic force of the first spring 32 and the second spring 34, the first limiting plate 33 and the second limiting plate 35 move synchronously towards the center, which can accurately position the terminal at the center of the lower pressure block 22, ensuring that the terminal is in the correct pressing position every time it is pressed, and significantly improving the pressing accuracy and product quality consistency.

[0047] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
