Strip plate punching auxiliary feed device

Abstract

The invention discloses a strip plate punching auxiliary feed device which is disposed between a punching equipment workbench and a feed mechanism. The auxiliary feed device comprises upper roll seats, lower roll seats and a support. The support is a double-layer rectangular frame. The upper surface of the bottom-layer frame is provided at least two sets of lower roll seats with equal height and at intervals along the feed direction. The rolls matched with the lower roll seats are positioning and rotating structures. The top outer wall of each horizontal roll is parallel with the punching equipment workbench. The upper roll seats hung on the top inner frame of the support are matched with the lower roll seats. The upper roll seats and the lower roll seats parallelly clamps a to-be-conveyed thin board, and the rolls upper roll seats perform elastic support. The bottom of the to-be-conveyed thin board is supported by the lower rolls with equal height, and the top thereof is elastically pressed by the upper rolls, and synchronous feed of the strip thin board under the straight state can be guaranteed, and stable quality of a punching part is guaranteed.

Description

technical field [0001] The invention relates to an auxiliary feeding device for stamping equipment, in particular, the invention relates to an auxiliary feeding device for punching which uses strip thin plates as raw materials. Background technique [0002] In the modern manufacturing industry, stamping is the main process to realize sheet metal forming processing. This process is formed by means of molds, with good forming consistency, stable quality and high production efficiency. However, if the thickness of the stamping material is less than 3mm in production, and the workpiece size is relatively large, the stamping equipment used will have a large worktable area, resulting in a long feeding distance. Due to the poor rigidity of the thin plate itself, the suspended thin plate cannot be kept parallel to the workbench, which affects the accuracy of subsequent feeding and makes the quality of stamping parts unstable.
