Description

Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to a lifting device for punching holes on the end face of a straightening machine. Background Art

[0002] In many manufacturing fields, such as mechanical processing, automobile manufacturing, aerospace, etc., it is often necessary to straighten and punch workpieces. The traditional production method is to first use a straightening machine to straighten the workpiece, and then transfer the workpiece to the punching equipment for punching. This is not only inefficient, but also prone to errors in the workpiece handling and repositioning process, affecting the processing accuracy.

[0003] The traditional step-by-step processing method is prone to cause dimensional deviation and surface quality problems of the workpiece, while the punching mechanism at the end of the straightening machine can achieve high-precision punching operations while ensuring the straightening accuracy of the workpiece, thereby improving the overall quality of the product; with the continuous development of automation technology and mechanical manufacturing technology, people began to seek a method that can realize straightening and punching operations on the same equipment, which prompted the research and development and application of the punching mechanism at the end of the straightening machine; by integrating the punching mechanism into the straightening machine, the workpiece can be clamped and straightened and punched in one go, greatly improving production efficiency and processing accuracy, while a single punching device is not compatible with workpieces of different diameters, and needs to be combined with an automatic lifting device to realize the positioning of the punching mechanism and achieve high-precision punching operations, thereby improving the overall quality of the product.

[0004] The Chinese patent application number is: 202410228501.9. The automatic punching equipment of the bearing seat comprises a mounting frame and a cross beam slide fixedly mounted on the top of the mounting frame, and the cross beam slide is equipped with a lifting punching machine. A work station bed for placing the bearing seat is fixed on one side of the mounting frame, and a sliding pressure box is provided on the work station bed for pressing and fixing the bearing seat to one side of the pressure frame plate. This limits the shaking displacement of the bearing seat. At the same time, a plurality of tensioning tubes that can be inserted into the shaft hole of the bearing seat are provided in the middle of the sliding pressure box. Each tensioning tube can be synchronously displaced and opened outward to tighten the shaft hole of the bearing seat. This can effectively further limit the bearing seat and prevent the bearing seat from lateral displacement and falling off, so as to facilitate the punching work of the lifting punching machine on the cross beam slide, save manpower and material resources, and improve the overall use stability and work efficiency.

[0005] However, during the punching process of the existing straightening machine punching lifting device, the lifting platform may shake and vibrate due to the impact force, which not only affects the punching quality, but also may affect the service life of the equipment.

[0006] In summary, the present invention provides a lifting device for punching holes on the end face of a straightening machine to solve the above problems. Utility Model Content
