Abstract
The utility model discloses a kind of process for suction casting filling time Simple measurement devices, it is related to casting filling technical field, the variation of liquid metal weight in cavity filling process in casting cavity filling process is inhaled in process for suction casting filling time Simple measurement device application, show that the net weight for inhaling casting room changes with highly sensitive electronic crane scale, the net weight modified-image for recording electronic crane scale and showing is shot by high-speed camera, the finish time that type is full of fixed weight is carved and filled at the beginning of filling type initial weight by graphical analysis, obtains inhaling the filling time for casting entire casting.The device precision is high, and response is fast, intuitively, and also it is easy to operate, it is at low cost, therefore have actual advantage in the filling time that can not directly observe process measures.
Description
Technical field
The utility model is related to casting filling technical fields, and specifically, the utility model is related to a kind of suction pouring works
Skill filling time Simple measurement device.
Background technology
Process for suction casting is that casting mold is placed in the suction casting room of sealing, and lower end stalk is immersed in liquid metal, then
Casting room will be inhaled to vacuumize, molten metal is made to fill type from bottom to top under negative pressure, and carry out the manufacturing process of cooled and solidified under negative pressure.
Pressure release after the completion of cooled and solidified, the molten metal reflux crucible molten bath in stalk.Since sealing of a mould is in inhaling in casting room, liquid is golden
The filling time of category is difficult to directly observe and measure.Research observation is mostly generally carried out using solidification simulation technology or hydraulic analogy,
But these methods are difficult to the filling time of the directly actual liquid of reaction.And the filling time of gravitational casting molten metal can be opened by filling type
Begin to pouring completely to terminate to be easy to be measured with stopwatch.It is general to inhale the short 0.1~5S of casting filling time.
Existing contact time method be by copper conductor be placed in inhale casting room in casting mold cavity peak and Zhi Xi roads suction inlet most
Low spot gathers the Continuity signal of conducting wire by data collecting card, when liquid metal by suction inlet minimum point and is filled to peak
When, the corresponding passage of capture card generates signal, so as to which obtain suction inlet minimum point and cavity peak fills type moment, time difference
It is just filling time.This method needs copper conductor being embedded in casting mold in advance, and guides to suction casting outdoor data capture card, it is necessary to multiple
Miscellaneous hardware and software systems, especially high speed, jamproof capture card are of high cost, and influence to inhale the sealing performance of casting room.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of process for suction casting filling time ordinary surveying dress
It puts, achievees the purpose that the measurement record for realizing that casting liquid metal inhales liquid metal filling time when type is filled in casting.
To achieve the above object, the utility model provides following technical solution：
The process for suction casting filling time Simple measurement device includes automatic weighing device, inhales casting chamber system and take the photograph at a high speed
Camera three parts, wherein, automatic weighing device includes a highly sensitive electronic crane scale, is lifted on by chain and inhales casting room
Top, inhaling casting chamber system includes inhaling casting room, inhales casting chamber interior and is equipped with casting mold and ceramic lift tube, inhales casting chamber system and is placed on electric furnace
The top of crucible, the display screen of high-speed camera alignment electronic crane scale are placed.
As the further optimization of the technical program, the camera shooting set of frequency of the high-speed camera is estimated filling time
1/100~1/1000.
As the further optimization of the technical program, the weight detecting response time of the electronic crane scale of the high sensitivity is
1/100s。
It is using the advantageous effect of above technical scheme：The process for suction casting filling time Simple measurement device passes through one
Platform high-speed camera inhales a highly sensitive electronic crane scale camera shooting record liquid metal casting and fills weight change before and after type, draws suction
Casting is filled the type beginning and end moment, that is, realizes the measurement of filling time.The process for suction casting filling time Simple measurement device
High certainty of measurement, device is simple, easy to operate, and the hardware and software equipments such as complicated capture card, oscillograph, measurement cost is not required
It is low.
