Description

Technical Field

[0001] The utility model relates to the field of office furniture production, in particular to a feeding device of a plate punching and shearing machine. Background Art

[0002] When making furniture, steel plates are a very important part. Steel plates must be punched and sheared into the required shape by a punching and shearing machine before they can be installed. During the punching and shearing process, the steel plates need to be transported to the punching and shearing machine. Since the processing and manufacturing plants mainly use small punching and shearing machines for punching and shearing, and the feeding is also done manually, it is not only laborious, but also causes vibrations during the punching and shearing process, causing harm to the human body.

[0003] After searching, the Chinese patent announcement number CN219464905U is disclosed, which is a shearing machine that is convenient for feeding, including a conveying seat, a shell is fixedly installed on the conveying seat, a plurality of rollers are arranged on the conveying seat, and a plate is arranged on the plurality of rollers. A lower blade is fixedly arranged at one end of the top of the conveying seat, and a material guide plate is fixedly arranged at one end of the conveying seat. A collecting trolley is arranged in the shell, a support rod is fixedly installed in the collecting trolley, and a buffer mechanism is arranged in the collecting trolley. A support plate is fixedly installed on the conveying seat, a first electric push rod is fixedly arranged on one side of the support plate, and a limit plate is fixedly arranged at one end of the first electric push rod. The patent drives two sliders away from each other through the buffer plate, and the two sliders drive two slide plates to slide on the support rod through two buffer rods, and compress two buffer springs, thereby achieving the purpose of buffering, so that when the plate enters the collecting trolley, the force of the plate falling can be slowed down, thereby avoiding the damage of the plate, and making it convenient for people to use.

[0004] However, the distance between the support plate and the shell in the above patent is fixed, which is not convenient for pushing longer plates. Moreover, longer plates are prone to tilt during the loading process, which affects the punching and shearing effect. Utility Model Content

[0012] Preferably, the bottom of the movable pressing plate is an inclined surface.

[0013] The beneficial effects are: a feeding mechanism is set up, and after the sheet material is clamped by two clamps, the mounting block is driven by a one-way screw to drive the support frame and the clamp to move, so as to transport the sheet material.
