Abstract

The utility model relates to an improved processing machine of reinforced bars, which is mainly characterized in that through direct drive of a leather belt drive pair, straightening rollers which can make high-speed rotation through a motor are arranged on a platform of a machine frame and between a left and a right reinforced bar feeding machines; the left ends of the straightening rollers are provided with guide sleeves; the internal parts are evenly distributed with plural groups of hole moulds composed of a straightening block of an upper conical surface and a straightening block of a lower conical surface; the hold moulds are adjusted by ladder-shaped screw bolts and are alternatively arranged, and when the reinforced bars pass through the straightening rollers which make the high-speed rotation, the high-speed straightening purpose can be obtained. Simultaneously, a bracket is provided with a box body of a shearing box; the internal part of the box body is provided with a cam shaft which is integrated with an input shaft and a shearing lever shaft and a discharge shaft which are parallelly provided with the cam shaft which is fixed with a shearing cam and a pushing cam, and the shearing lever shaft is provided with a shearing lever which is provided with a cutting knife on one head in a sliding manner. When the input shaft drives the cam shaft to rotate, the shearing cam can rotate and can cause the shearing lever to move; the up-and-down movement of the cutting knife can shear the reinforced bars, and the high-speed shearing purpose can be realized.

Description

The high speed concrete-bar straightening and cutting machine

Technical field

The utility model is a kind of improved steel bar processing machinery.

Technical background

Existing domestic concrete-bar straightening and cutting machine often adopts the cross roll formula to change the hub aligning and crank block cuts off, and not only machine utilization is big, the fault rate height, and production efficiency is low, and vibrating noise is big, and operating environment is poor, the needs that can not adapt to the high speed aligning and cut off.

The purpose of this utility model is a kind of high speed concrete-bar straightening and cutting machine of design, aligning speed height, and the highest aligning speed can reach 120 meters/minute, cuts off the frequency height, and accurate positioning is satisfied the needs of high-speed production fully, and can be reduced noise effectively, improves working environment.

The purpose of this utility model is achieved like this: a kind of high speed concrete-bar straightening and cutting machine of being made up of frame, motor, belt transmission pair, feed appliance etc., it is characterized in that the inside installation conical surface aligning piece of rotation at a high speed being set and compressing the smoothing roll of adjusting trapezoidal bolt, employing rotary hub type casement is aligned the high speed aligning of realizing reinforcing bar, and setting is by rotary flyweights and pneumatic clutch is controlled the cam revolute of importing power and the high speed that the cutting knife head is realized reinforcing bar cut off.

It is rational in infrastructure that the utility model improves fast concrete-bar straightening and cutting machine, and aligning speed and cut-out frequency height are safe and reliable, and effectively improve working environment.
