Abstract
The utility model discloses a manual bending machine comprising a base. A left pin and a right pin are mounted at the upper ends of the left side wall and the right side wall of the base respectively. An eccentric shaft is rotationally mounted between the left pin and the right pin. Eccentric-shaft holes are formed in the left end and the right end of the eccentric shaft respectively. Bearings are fixedly mounted on the pins. A blade holder is mounted below the eccentric shaft. Reset spring bases are fixedly mounted at two ends of the blade holder respectively. The upper ends of the reset spring bases are fixedly connected with the base. The manual bending machine is high in bending efficiency, smooth in rotation and not easy to get stuck.
Description
Technical field
The utility model relates to a kind of manual bending machine.
Background technology
In prior art, there is structural instability in manual bending machine, and bending efficiency is low, and the rotation of eccentric shaft is easily stuck, gets rusty easily, and produces a large amount of noises.
Utility model content
It is high that the utility model object is to provide a kind of bending efficiency, rotates smooth and easyly, is difficult for stuck manual bending machine.
The utility model technical solution problem provides following scheme:
A kind of manual bending machine, comprise support, it is characterized in that: the arranged on left and right sides wall upper end of described support is separately installed with left and right two bearing pins, between described left and right two bearing pins, be rotatablely equipped with eccentric shaft, the left and right two ends of described eccentric shaft are provided with eccentric pivot hole, on described bearing pin, are installed with bearing, and described eccentric shaft below is provided with blade bearing, the two ends of described blade bearing are installed with return spring holder, and the upper end of described spring base is fixedly connected with support.
The lower end of described blade is provided with blade pad, and the surface of described blade pad is provided with v-depression.
The utility model is installed with bearing pin in the arranged on left and right sides wall upper end of support, and be installed with bearing on the sidewall of bearing pin, eccentric shaft rotates between bearing pin like this, the rotation of eccentric shaft can be pressed in blade upper end like this, and blade, to pressing down, can will be treated the steel plate of bending like this, and be installed with back-moving spring on the both sides of blade, after blade presses down like this, blade can be upspring automatically, carries out the preparation of bending next time.
