Description

Technical Field

[0001] The utility model relates to the technical field of blanking devices, in particular to a fixed-length blanking device for a metal piston rod. Background Art

[0002] The piston rod is a connecting component that supports the piston to do work. It is mostly used in oil cylinders and cylinder motion actuators. It is a moving component that moves frequently and has high technical requirements. Taking the hydraulic cylinder as an example, it is composed of a cylinder barrel, a piston rod (cylinder rod), a piston, and an end cover. The quality of its processing directly affects the life and reliability of the entire product. A cutting device is required when processing the piston rod. According to the publication number: CN211218985U, a cutting and blanking device for piston rod processing is disclosed, including a cutting table, a moving frame is fixedly connected to the top of the cutting table, a slide groove is provided at the bottom of the inner cavity of the moving frame, and a moving block is fixedly connected to the inner cavity of the slide groove through a slider. The front and rear sides of the top of the moving block are fixedly connected to pillars, and a driving member is arranged on the back of the moving block. The driving member includes a motor, and the left side of the motor is fixedly connected to the right side of the moving block. The output end of the motor is fixedly connected to a gear through a rotating shaft, and a rack plate is meshed on the surface of the gear. The utility model achieves the advantage of easy automatic unloading by arranging a cutting table, a moving frame, a slide groove, a moving block, a pillar, a driving part, a fixed block, an electric cutting wheel, a slide column, a support plate and an electric push rod that cooperate with each other. It does not need workers to perform frequent manual operations, reduces work intensity, and does not delay the progress of processing and production. However, the above technology still requires some cleaning. For example, the existing unloading device is easy to cause damage to the piston rod during use because there is no protective structure designed inside the collection box. After the collection is completed, the staff is required to take out the piston rod inside the collection box. The practicality is poor and needs to be improved. Utility Model Content

During use, when the slicer cuts the piston rod, the electric telescopic rod can be used to drive the piston rod to slide forward and slide into the collection box through the guide groove and the inclined plate. At this time, the protective pad inside the collection box can protect the piston rod, thereby avoiding the situation in which the piston rod is easily damaged during use due to the lack of a protective structure inside the collection box like the existing unloading device, and the staff is required to take out the piston rod inside the collection box after the collection is completed.

[0013] 2. The utility model is provided with a stopper, a threaded rod, a turning handle and a fixing groove, so that it is more convenient to replace the slices after long-term use.
