Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically a telescopic lifting lever punching machine. Background Technology

[0002] In the field of material processing, punching machines occupy a crucial position due to their diverse classifications and powerful functions. Based on the differences in the materials they process, punching machines are mainly divided into flexible sheet punching machines and membrane switch punching machines. Each type offers unique advantages for different material characteristics. Flexible sheet punching machines are specifically designed for flexible materials, which are often soft and highly ductile, easily wrinkled or torn during processing. To avoid these problems, flexible sheet punching machines have undergone extreme optimization in controlling punching pressure and speed. They can automatically adjust the impact force based on parameters such as the thickness and toughness of different flexible materials, ensuring smooth penetration of the material without damaging it due to excessive force. Precise control of punching speed ensures smooth and stable punching action, reducing deformation of materials under instantaneous stress. For example, in processing flexible circuit boards, the flexible circuit board punching machine perfectly adapts to their thinness and deformability, punching holes that meet requirements, laying a solid foundation for subsequent component installation. Membrane switch punching machines focus on the precision machining of tiny holes. As a common component in electronic devices, the accuracy of the hole diameter in membrane switches directly affects the conductivity and stability of the switch contacts. Even a micron-level deviation can lead to poor switch contact, affecting the normal operation of the entire equipment. Membrane switch punching machines, with their advanced positioning systems and high-precision punches, can punch extremely small diameter holes in membranes. These punching machines, with their extremely small tolerances, demonstrate exceptional precision in minute details, ensuring that the position and size of each hole perfectly conform to design standards. This guarantees stable and reliable operation of the membrane switch during use. Their applications are widespread, appearing in the punching processes of circuit boards, printed circuit boards, film boards, and films, playing an indispensable role in numerous industries such as electronics, intelligent manufacturing, and packaging printing. It can be said that efficient and stable punching equipment is key to ensuring the quality and production efficiency of materials and various processing methods. In short, efficient and stable punching equipment is crucial for ensuring the quality and production efficiency of materials and various processing methods, particularly in the electronics and information technology sector. In the industrial sector, punching precision directly affects the signal transmission efficiency of circuit boards and the stability of equipment operation. Even a tiny deviation in hole diameter can lead to short circuits or poor contact. In the field of intelligent manufacturing, standardized punching quality is the foundation for the smooth operation of automated assembly lines, reducing production line downtime caused by material compatibility issues. In the packaging and printing industry, precise punching enables rapid splicing and sealing of packaging materials, improving product packaging efficiency and sealing performance. It is evident that the performance of punching equipment not only affects the cost and efficiency of a single processing stage but also directly relates to the product quality and market competitiveness of downstream industries. It is of great significance for promoting technological upgrades, achieving intelligent manufacturing transformation, and sustainable development in related industries. However, traditional punching machines often struggle to adapt to materials with dimensional deviations or misaligned placement due to their fixed and non-adjustable lifting structure. Their lifting components are typically single, fixed rods; when the material shifts to one side beyond the lifting range, instability and material swaying easily occur, affecting punching accuracy and potentially causing material deformation or equipment malfunction due to uneven stress. Furthermore, adjusting the lifting width of traditional equipment often relies on manual disassembly and reassembly, which is cumbersome and time-consuming, making it difficult to adapt to the diverse material specifications required in mass production and severely restricting processing efficiency. Therefore, those skilled in the art have provided a telescopic lifting lever punching machine to solve the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide a retractable lifting lever punching machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A telescopic lifting lever punching machine includes a support structure and an adjustment structure. The support structure includes a first support column, a second support column, a third support column, and a fourth support column, all of which are vertically distributed. The second and fourth support columns each have a groove on one side, and an adjustment structure can be detachably connected to each groove.

[0005] As a further embodiment of this utility model: the adjustment structure includes a short rod, a first snap-fit ​​plate and a second snap-fit ​​plate, a connecting frame is fixedly connected to one side of the second snap-fit ​​plate, the first snap-fit ​​plate is detachably connected to the connecting frame, and corresponding connecting holes are provided on both the first snap-fit ​​plate and the connecting frame.

[0006] As a further embodiment of this utility model: a first mounting block is fixedly connected to one side of the top of the first snap-fit ​​plate, and a second mounting block is fixedly connected to the other side of the top of the first snap-fit ​​plate. The second mounting block and the first mounting block are fixedly connected by a short rod.

[0007] As a further embodiment of this utility model: a cylinder is fixedly connected to one side of the first snap-fit ​​plate on the adjustment structure, and a connecting plate is fixedly connected to the side of the second snap-fit ​​plate near the first snap-fit ​​plate.

[0008] As a further embodiment of this utility model: the power output end of the cylinder on the side away from the first snap-fit ​​plate passes through one side of the connecting plate and is fixedly connected to a support rod, and a connecting block is fixedly connected to the other side of the support rod.

[0009] As a further improvement of this utility model, a first fixing block is fixedly connected to the upper part of the opposite side of the first support column and the third support column.

[0010] As a further embodiment of this utility model: the upper part of the opposite side of the second support column and the fourth support column are both fixedly connected to the second fixing block, and the first fixing block and the second fixing block that are laterally corresponding are rotatably connected to the support member.

[0011] As a further embodiment of this utility model: the top of the second fixing block is detachably connected to a pressing block, the bottom of the second fixing block is detachably connected to a pressing block, a third mounting block is fixedly connected to one side of the pressing block, and a pressing component is rotatably connected between the third mounting block and the pressing block, and the corresponding pressing component and support component are vertically parallel.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, firstly, the basic support of the equipment is composed of a stable vertical frame formed by the first support column, the second support column, the third support column and the fourth support column. Among them, the second support column and the fourth support column are provided with grooves on one side. These grooves serve as the installation carriers for the adjustment structure, cleverly forming a symmetrical adjustment unit, which lays a solid structural foundation for the realization of the subsequent telescopic function. 2. In the adjustment structure, the second snap-fit ​​plate is detachably connected to the first snap-fit ​​plate via a connecting frame and corresponding matching connecting holes. This design allows for coarse adjustment of the lateral position of the first snap-fit ​​plate by adjusting the alignment of the connecting holes. The short rod fixed to the top of the first snap-fit ​​plate by the first mounting block and the second mounting block acts as a basic support structure, stably supporting the middle of the material. When the material is misaligned, causing the short rod to be unable to fully support it, the cylinder fixed on one side of the first snap-fit ​​plate will start working. Its power output end passes through the connecting plate on the second snap-fit ​​plate and drives the support rod to extend and retract. With the independent control of the cylinders on both sides, the support rod can extend precisely in the direction of material misalignment, thereby supplementing support and ensuring the stability of the material. 3. At the same time, the first and third support columns are rotatably connected in the same horizontal position through the first fixing block, and the second and fourth support columns are rotatably connected through the second fixing block, forming a horizontal lifting reference surface. The pressing block at the top of the second fixing block is rotatably connected to the pressing block through the third mounting block, and is vertically parallel to the support. The two cooperate with each other to achieve auxiliary clamping and positioning of the material, further enhancing the stability of the material during the lifting process. 4. Overall, the equipment combines coarse adjustment of the connecting hole with fine extension and retraction of the cylinder-driven support rod, and works in conjunction with the support and pressing components to successfully and stably lift misaligned materials. This effectively solves the problem of insufficient lifting range of a single short rod, and thus meets the support requirements of punching operations for materials in different positions.
