Abstract

The utility model relates to a colour floor tile press, comprising a four-column machine body, a piston oil cylinder, a liftout attachment for stratification quantitative laying products, an electric motor oil pump device and a hydraulic controller. The four-column machine body is composed of an upper cross beam, a lower cross beam, an upright column, a round nut and a machine base which are connected together. The utility model is characterized in that the piston oil cylinder adopts a parent-daughter type oil cylinder, the piston oil cylinder is composed of two sets of concentrically installed oil cylinder pistons, and one oil cylinder piston is big and the other is small. The cylinder body forms A, B and C sealed working chambers with the upper end of a large piston, the lower end of a small piston and the inner chamber of a large piston rod respectively. The press adopts the parent-daughter type oil cylinder to drive, and the oil cylinder has high pressure, small flow and single pump, when the large piston has reciprocating motion to do work, the acceleration of lost motion is realized, and the heavy load travel of the stress of a contact workpiece has automatic deceleration and pressurization. The utility model has high and low pressure double pump driving effect, having high pressure, high speed, low energy consumption and high productive efficiency.

Description

The colour floor brick press

The utility model relates to a kind of colour floor brick press, is used for the various colour floor brick products of pressure forming.

Common colour floor brick press and common four-column hydraulic press are alike, but middle no moved cross beam.Its structure is formed a vertical body by entablature, sill, column, round nut, support, fixed installation one cover piston oil-cylinder parts in the entablature centre bore, and disposing a cover high-pressure low-flow pumping station system separately, transmission control oil cylinder piston low speed moves back and forth work done (press forming adobe).Because adopt the single piston of single pump drive, pressure and translational speed can't accomplish that both take into account, so this press pressure is little, and speed is slow, inefficiency.

The purpose of this utility model provides a kind of colour floor brick press of being made up of the primary-auxiliary type oil cylinder.

The structure of the colour floor brick press that the utility model proposes comprises entablature, sill, column, round nut, support, connect into four post bodies, fixing assembling piston oil-cylinder in the entablature centre bore, the sill side is layered quantitative stone goods liftout attachment fixedly, the motor pump device is installed in the sill back side, hydraulic control device is installed in the entablature top and is connected with oil pump with oil pipe, entablature inner chamber double as fuel tank, it is characterized in that piston oil-cylinder adopts the primary-auxiliary type oil cylinder, it is to be made of the oil cylinder piston that small one and large one two cover is installed with one heart, the small oil tank piston is installed in the inner chamber of large tank piston rod, and this inner chamber is as the oil cylinder of valve piston.

The colour floor brick press compactness rational in infrastructure that the utility model proposes.Replace common single piston oil-cylinder with the primary-auxiliary type oil cylinder, when realizing that high-pressure low-flow list pump drive big piston moves back and forth work done, the lost motion speedup, the supercharging of slowing down automatically of the stressed heavily loaded stroke of contact workpiece, effect with the transmission of high-low pressure double pump reaches the purpose that pressure is big, speed is fast, efficient is high.

Followingly concrete enforcement of the present utility model is further described with reference to accompanying drawing.

Shown in Figure 1 is the overall structure figure of this colour floor brick press;

Shown in Figure 2 is the F-F portion view (primary-auxiliary type cylinder structure figure) of Fig. 1;

Shown in Figure 3 is primary-auxiliary type oil cylinder list pump drive hydraulic control schematic diagram.

The structure of this colour floor brick press is by entablature 3, sill 6, column 4, round nut 7 and support 9 connect into four post bodies, fixing assembling piston oil-cylinder 2 in entablature 3 centre bores, layered quantitative stone goods liftout attachment 5 is installed in sill 6 sides, motor pump device 8 is installed in sill 6 back sides, hydraulic control device 1 is installed in entablature 3 top oil pipes, be connected with motor pump device 8, entablature 3 inner chamber double as fuel tanks (referring to Fig. 1), it is characterized in that piston oil-cylinder 2 adopts the primary-auxiliary type oil cylinder, it is to constitute (referring to Fig. 2) by the oil cylinder piston that small one and large one two cover is installed with one heart, cylinder body 10 is fixedlyed connected with fairlead 16, big piston 11 is fixed on the big piston bar 12 and is installed in the cylinder body 10, big piston 11 upper ends and cylinder body 10 form the C chamber, valve piston 15 is fixed on the small piston rod 14 and is installed in the inner chamber of big piston bar 12, small piston rod 14 hollow lumen are installed petroleum pipeline 13, valve piston 15 upper ends and big piston bar 12 inner chambers form the B chamber, valve piston 15 lower ends and big piston bar 12 inner chambers are split into the A chamber, constitute A thus, B, three seal operation chambeies of C.

The course of work is referring to Fig. 3

Motor 24 energising, oil pump 23 starting rotations, pipeline 25 produces negative pressure, and the oil in the fuel tank filters through oil filter 17 and is inhaled into output again in the oil pump 23, advances solenoid directional control valve 18 through pipeline 22, and P mouth to 0 mouthful filters oil sump tanks through oil filter 17, and this circulation is a unloading condition.When 18 commutations of 1CT energising reversal valve, PA mouth and BO mouth are connected, it is downward that pressure oil advances A chamber promotion big piston, C chamber generation negative pressure, and check valve 21 is inhaled to be opened, oil in the fuel tank is sucked into the C chamber, big piston moves downward fast and is subjected to resistance oil to workpiece and presses and to be increased to the setting of sequence valve 20 and to open, and pressure oil enters the C chamber, and check valve 21 is closed automatically, the big piston supercharging, movement velocity slows down.1CT outage 2CT energising, reversal valve 18 commutations, PB mouth and AO mouth are connected, pressure oil enters the B chamber and promotes big piston upwards, and check valve 21 hydraulic control mouth pressures raise and back down, and the oil in C chamber flows back to fuel tank, the oil in A chamber was through reversal valve 18 when big piston moved upward fast, AO mouth, oil filter 17 oil sump tanks.Overflow valve 19 is used to set up operating pressure, and the 2CT outage is in unloading condition again.
