钢坯是轧钢生产中最常见的材料之一，也是轧钢生产中需求量很大的一种材料，而且，钢坯的尺寸一般比较大，重量也表较重。因此，钢坯的搬运就比较困难，所以，设计一种专门搬运大重型工件的搬运机构是很有必要的。液压全自动步进上料机就是一种用于轧钢生产中搬运钢坯的机器。它的工作原理是：由电机带动抬起液压缸，提供动力，带动抬起拉杆运动。从而使抬起梁完成上下运动，这样来实现钢坯的抬起和放下。平移液压缸提供水平方向上的动力，使车体带动钢坯完成水平方向上的运动。液压全自动步进上料机构能够有效的提高生产率，减轻工人的劳动强度。

Title  The design of hydraulic automatic step feeding machine—the design of collectivity and mainframe       

Abstract
Billet is a very common material in steel rolling manufacture, and it’s requirement is very prodigious in steel rolling manufacture, and the measurement usually large, and its weight usually very heavy. So, to carry the billet becomes very hard, and so it is very necessary to design a special machine to carry big and heavy workpiece. Hydraulic automatic step deliver machine is just the machine used to carry the billet in steel rolling manufacture. Its work principle is as follows: the electromotor drive the uplifting hydraulic cylinder and offer motivity to drive the uplifting pole moving. Consequently make the uplifting pole finish up and down movement, in this way ,the billet can be uplifted and lay put down. Horizontal ambulant hydraulic cylinder offer horizontal motivity to make the bodywork finish horizontal movement. Hydraulic automatic step deliver machine can heighten the productivity and lighten the worker’s working intensity effectively.

Abstract
In this topic design food machinery uses the high-pressured viscolizer, its principle of work is: Uses the electric motor after the level V belt transmission deceleration, leads crank revolving, the crank throw crank causes with in the crank hinge connecting rod impetus piston cylinder piston to make the straight reciprocating main motion in the piston cylinder, thus the impetus level hydraulic valve and two level of hydraulic valve function, produces the strength attracts, the row of mix material, achieves the even mix the goal.
According to the electrical machinery working conditions choice electric motor type, uses the horizontal-type installment, the protected electric machine, the mouse cage type three-phase asynchronous motor. The choice belt transmission, it has the cushion, attracts inspires, the movement steadily, the noise small, gathers merits and so on over-load protection, and installs the stretching pulley. Two level of gear reductions, the gear drive available transmits the movements and the power between the spatial willfully two axes, and has the power scope to be big, the transmission efficiency is high, the velocity ratio is accurate, the service life is long, job safety reliable and so on characteristics. The power outputs by the electric motor, through the retrosystem transmission, inputs the power to the implementing agency. Because the transmission system does is the gyroscopic motion, in the piston cylinder liquid must realize the isotropic goal in the piston straight reciprocating motion, may use the crank slide organization, the plate good cam migration roller from the moving parts organization, the gear rack work. This topic uses the crank slide organization to take this machinery the implementing agency.
