Description

Technical Field

[0001] The invention relates to the field of punching devices, and in particular to a precise punching device for pen processing. Background Art

[0002] Fountain pens are commonly used writing instruments. When processing the pen shell, a punching device is required. Currently, the punching devices on the market generally have multiple functions integrated into one production, such as punching, turning and cutting functions. However, there are still certain problems in use. For example, traditional punching devices cannot achieve continuous processing with continuous feeding when processing pen shells. During processing, workers are required to place metal columns of fixed length in a fixture for the punching device to perform punching, turning and cutting. After the cutting is completed, workers are required to remove the remaining metal columns in the fixture and re-clamp new metal columns for subsequent processing. Although the processing purpose can be achieved, the processing efficiency is undoubtedly low. At the same time, when performing the turning and cutting steps, the traditional punching device installs components for turning and cutting on the punching device respectively, and the turning and cutting components are not integrated together, which will cause the entire equipment to look more messy and complicated, and will also increase the cost of mounting and fixing parts during installation. Summary of the invention

[0003] The purpose of the present invention is to provide a precise punching device for pen processing, which has the advantages of high processing efficiency and high degree of integration.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: it includes a base, the bottom of the base is equipped with supporting legs, the top of the base is equipped with a controller through a fixing piece, the top of the base is equipped with a sleeve through a fixing piece, the interior of the sleeve is provided with a cylinder, the interior of the cylinder is provided with a card block, the number of the card blocks is four, one end of the sleeve is provided with a connecting seat, the card block is provided with an adjustment groove, the interior of the adjustment groove is provided with an adjustment block, the top of the base is symmetrically provided with a displacement mechanism, the top of the base is provided with a rotation mechanism, the top of the base is symmetrically bolted with a fixing block, a first hydraulic cylinder is installed at the center of the fixing block, the output end of the first hydraulic cylinder is fixedly sleeved with a mounting seat, and a stepping motor is installed on the mounting seat The output end of the stepping motor is fixedly sleeved with a guide conveying wheel, the top of the base is bolted with a frame, a moving mechanism is arranged inside the frame, a second hydraulic cylinder is arranged on the top of the base, and a punching mechanism is fixedly sleeved on the output end of the second hydraulic cylinder, a third hydraulic cylinder is arranged on the top of the base, and a mounting block is fixedly sleeved on the output end of the third hydraulic cylinder, a turning seat is bolted on the mounting block, a turning block is bolted on the turning seat, a storing groove is provided on the turning block, a cutting knife is slidably connected to the inside of the storing groove, a groove is provided inside the storing groove, a fourth hydraulic cylinder is installed on the turning block through a fixing member, a first push block is bolted on the cutting knife, and the output end of the fourth hydraulic cylinder penetrates into the inside of the groove and is fixedly sleeved with a second push block.
