Fig. 2 is the structural representation of a kind of static pressure brick machine of the present invention.
Fig. 3 is that in Fig. 2, the installation site of the photoelectric protector shown in left apparent direction and frame is related to schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 2 and Figure 3, a kind of static pressure brick machine that the present embodiment provides, comprise frame 12, press brick oil cylinder 5 to be installed on the top of frame 12, press the piston rod of brick oil cylinder 5 to stretch out downwards, tup 6 is installed on the top of pressing brick oil cylinder 5 piston rods, and mould 8 is positioned at tup 6 belows and charge door upward, press brick oil cylinder 5 can drive tup 6 that the refractory material in mould 8 is pressed into refractory brick, below mould 8, be also provided with the brick device that goes out of refractory brick ejection die 8; Photoelectric protector 7 is installed on the front end of frame 12, and when work, whether photoelectric protector 7 is for detection of having object to enter frame; Upper limit device 13 is installed in the frame 12 of pressing brick oil cylinder 5 sides, upper limit device 13 comprises upper limit position block 131 and lower position block 132, the shielding plate 21 of responding to mutually with upper limit position block 131 and lower position block 132 is installed on tup 6, and upper limit position block 131 and lower position block 132 are in order to carry out spacing to the upper-lower position of tup 6; Press brick oil cylinder 5 to be connected with Hydraulic Station 15 oil circuits, upper limit device 13, photoelectric protector 7 are connected with the input of PLC control device 14, and the output of PLC control device 14 is connected with Hydraulic Station 15.In the present embodiment, go out brick device and comprise brick output oil cylinder 16, brick output push rod 9, brick output pressure pin 10; Brick output push rod 9 is positioned at mould 8 bottoms, brick output pressure pin 10 is positioned at brick output push rod 9 bottoms and is fixed on the top of brick output oil cylinder 16 piston rods, brick output oil cylinder 16 piston rods protrude upward the refractory brick that can drive in brick output push rod 9 ejection dies 8, brick output oil cylinder 16 is connected with Hydraulic Station 15 oil circuits, and the top of brick output pressure pin 10 is bowl shaped structure.The brick device that goes out that uses brick output oil cylinder 16 formations, simple in structure, installation and maintenance is all more convenient, in addition, producing different-thickness, during the refractory brick of intensity, need to change the mould 8 with different cavity depths, this ejection height that will obtain brick oil cylinder 16 piston rods also changes thereupon, if the piston rod by brick output oil cylinder 16 directly ejects refractory brick, so along with the difference of the different mould 8 inside cavity degree of depth, just need to change different brick output oil cylinders 16, could meet the difference of ejection height, in the present embodiment, be provided with brick output push rod 9 and brick output pressure pin 10, by changing the brick output push rod 9 of different length, just can eject different-thickness, the refractory brick of intensity, thereby reduced use cost, the top of brick output pressure pin 10 is bowl shaped structure, mainly plays the effect that brick oil cylinder 16 piston rods can accurately push up brick output push rod 9 of using, and smooth brick output.In actual production, brick output push rod 9 moves up and down frequently, makes its wearing and tearing more serious, is difficult to guarantee concentricity requirement, so use bowl type structure, reduces the requirement of concentricity, and arcuate structure can make force localization in center a bit.In the present embodiment, be also provided with lower retainer 11, lower retainer 11 is installed in the frame 12 of brick output pressure pin 10 sides, and lower retainer 11 is connected with PLC control device 14 inputs.When brick output pressure pin 10 is descending, can trigger lower retainer 11.
A kind of static pressure brick machine that the present embodiment provides, the course of work is followed successively by: one, operative employee carries out hand charge, refining to mould 8, two, after having fed in raw material, when tup 6 and brick output pressure pin 10 are all positioned at initial position, be the tup position of shielding plate 21 can shelter from upper limit position block 131 in upper limit device 13 time, position when brick output pressure pin 10 can shelter from lower retainer 11, operative employee could send instruction by 14 pairs of Hydraulic Stations 15 of PLC control device, make to press brick oil cylinder 5 piston rods slowly descending, drive tup 6 to press brick action, when shielding plate 21 shelters from the lower position block 132 of upper limit device 13, upper limit device 13 can send signal to PLC control device 14, then PLC control device 14 can send halt instruction to Hydraulic Station 15, make to press brick oil cylinder 5 piston rods stop descending and keep a period of time, the height of upper limit device 13 lower limit position pieces 132 is according to producing different-thickness, the refractory brick of intensity is set.In pressing brick process, if having detected object, photoelectric protector 7 enters frame 12, can send signal to PLC control device 14, PLC control device 14 can send halt instruction to Hydraulic Station 15 at once, make to press the piston rod of brick oil cylinder 5 to stop descending, after only having and again resetting, just can work on, three, after pressing brick to complete, PLC control device 14 sends instruction to Hydraulic Station 15, make to press brick oil cylinder 5 piston rods up, when shielding plate 21 shelters from the upper limit position block 131 of upper limit device 13, upper limit device 13 can send signal to PLC control device 14, and then PLC control device 14 sends instruction to Hydraulic Station 15, makes to press brick oil cylinder 5 piston rods to stop up, be that tup 6 rises to assigned address, in upper limit device 13, the height of upper limit position block 131 is to set according to brick output and reinforced comfort level, four, only have and rise to assigned address and upper limit device 13 sends after signal when tup 6, operative employee could send instruction to Hydraulic Station 15 by PLC control device 14, use brick oil cylinder 16 piston rods up, drive brick output pressure pin 10 to withstand brick output push rod 9, refractory brick in brick output push rod 9 ejection dies 8, when operative employee takes out after refractory brick, operative employee can signal to Hydraulic Station 15 by PLC control device 14, using brick oil cylinder 16 piston rods stops up and descending, when brick output pressure pin 10 goes downwards to can shelter from lower retainer 11 time, lower retainer 11 is just sent signal to PLC control device 14, then PLC control device 14 sends instruction to Hydraulic Station 15, using brick oil cylinder 16 piston rods stops descending, be that brick output pressure pin 10 goes downwards to assigned address.And then repeat to feed in raw material, press brick, the action of brick output.
Advantage of the present invention is: one, use to press brick hydraulic oil cylinder driving tup to press brick, cylinder piston rod motion slowly, and has upper limit device to carry out position-limiting action and photoelectric protector to detect and have or not object to enter frame, than hitting, press stock mould formula more safe and reliable; Two, press brick hydraulic oil cylinder driving tup to press brick, brick output hydraulic oil cylinder driving brick output push rod brick output, simpler in structure, power consumption has saved 30% than originally, and maintenance cost has saved 75% than originally; Three, noise obviously reduces, and has reduced by 80% dust; Four, hit the stock mould formula of pressing, easily make die cavity wearing and tearing, and press brick hydraulic oil cylinder driving tup to press stock mould formula, because be static pressure, so die cavity wearing and tearing obviously reduce, and press brick process to be controlled by PLC, do not exist because stealing hammer, leaking the product quality problem that the violation operations such as hammer cause, the indices of refractory brick is remained in a stable numerical value, improved yield rate.
