The utility model content
Main task of the present utility model is to provide a kind of material injecting device of hydraulic machine for magnetic material, specifically is a kind of material injecting device that can regulate the hydraulic machine for magnetic material of shot automatically.
In order to solve above technical problem, the material injecting device of a kind of hydraulic machine for magnetic material of the present utility model is made of hopper, barrel, agitating device, material feeding cylinder, and described hopper is fixed on the barrel, in barrel in agitating device; Described material feeding cylinder is connected with barrel; It is characterized in that: the automatic compensation adjustment device that on the material feeding cylinder, is provided with shot.
The automatic compensation adjustment device of described shot is: respectively be provided with a piston cylinder in the both sides of material feeding cylinder; The piston rod of described piston rod and material feeding cylinder is all fixedlyed connected with slide block, and described slide block also is connected with adjusting device.
Described adjusting device reaches the screw mandrel that is connected by gear with motor for the frequency modulation drive motors; Fixed dam on the described screw mandrel connects guide rod in the baffle plate both sides.
The advantage of above structure is: be connected with the automatic compensation adjustment device of shot on the material feeding cylinder, regulate shot automatically by the automatic compensation adjustment device of shot, satisfy the needed material amount of finished product moulding in the die cavity.Prevent the global formation of the overflow destruction product that the material amount too much causes, and the product that the material amount causes very little can't moulding.Improve production efficient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a side view of the present utility model shown in Figure 1;
Fig. 3 is the utility model partial view shown in Figure 1.
The specific embodiment
As shown in Figure 1, 2, built-in heater 20 and paddle 2 in the barrel 1 of the present utility model, described paddle 2 upper ends are connected with motor 3 as the power source that stirs.
Bottom at barrel 1 is communicated with material pipe 4, connects material sucking valve 5 on the described material pipe 4, is connected with material feeding cylinder 6 by material sucking valve 5.Described material feeding cylinder 6 logical charge tubes and feeding materials valve 21 are connected to mould.The both sides of described material feeding cylinder 6 are provided with two piston cylinders 7,8, and two-piston cylinder 7,8 is all fixedlyed connected with slide block 12 with the piston rod 9,10,11 of material feeding cylinder 6.Described slide block 12 is fixedlyed connected with adjusting device.
As shown in Figure 3, described adjusting device is made of frequency modulation drive motors 13, screw mandrel 14, guide rod 15, and described frequency modulation drive motors 13 connects screw mandrel 14 by gear 16, and fixed stop 17 on screw mandrel 14, are provided with stroke limit sensor 19 in the both sides of block 17.The other end of described screw mandrel 14 is connected with slide block 12, in order to control the stroke of material feeding cylinder, on slide block 12 with stroke limit sensor 19 mutually mutual induction fixing limited block 18.
During operation, the position of limited block needs to adjust to setting numerical value by mould, then material is thrown into barrel 1, after stirring by heater 20 heating and by paddle 2.At this moment, under the instruction of PLC, close feeding materials valve 21 and open material sucking valve 5 simultaneously, move behind the piston rod 11 of the moving material feeding cylinder 6 of piston rod 9,10 back shipper poles of material feeding cylinder 6 both sides, thereby suck the material in the barrel 1, when moving on to behind the slide block 12 after limited block 18 receives stroke limit sensor 19 instruction, move after stopping, closing material sucking valve 5 simultaneously, open feeding materials valve 21 material feedings.
Specific embodiment:
Present embodiment is the automatic Compensation Regulation step of the shot of material feeding cylinder:
Material feeding piston stop position:
Material feeding piston stop position needs to adjust accordingly by mould, and when continuing operation automatically, to adjust automatically according to green compact thickness. after suppressing normal green compact, import current material feeding piston stop position on this hurdle, to remember. when reusing same mould, data by this hurdle memory are readjusted current material feeding piston stop position, setting range: 0.0-300.0 material feeding stand-by period:
Set the stand-by period of touching the material feeding action beginning of closed back up and down.
The material feeding time:
Setting the Looking Out Time of material feeding action, if exceed this time, then is unusual.
Green compact thickness correction:
The position of lower slider measures the products thickness data automatically when finishing according to pressurization; if in the extent of amendment that institute's Thickness Measurement by Microwave is setting; be institute's Thickness Measurement by Microwave greater than the products thickness higher limit less than (the products thickness upper limit+extent of amendment) or institute's Thickness Measurement by Microwave less than the products thickness lower limit during greater than (products thickness lower limit-extent of amendment); then adjust automatically according to the injection rate correction; if so that products thickness reaches tolerance band. institute's Thickness Measurement by Microwave has exceeded above-mentioned adjustable range; it is unusual then to be judged as products thickness, autostop.
Example:
Products thickness measured value=Amm
Products thickness higher limit=10.5mm
Products thickness lower limit=10.00mm
Extent of amendment setting value=0.20mm
Injection rate is not adjusted automatically: 10.00mm≤A≤10.50mm
Injection rate is adjusted automatically: 9.80≤A＜10.00mm or 10.50mm＜A≤10.70mm
The unusual Rule of judgment of products thickness: A＜9.8mm or A＞10.70mm
Set the adjustment of injecting device piston positive stop.
If the products thickness of surveying in the extent of amendment of setting, then the correction of the setting of basis is adjusted injecting device piston positive stop position, correction+/-will judge automatically by press.
