Cast Iron Surface Box

The cast iron surface box is a plane reference tool for workpiece detection or marking.During the inspection,the working surface shall be painted and checked.The number of touch points in 25mm×25mm shall be no more than 5 after the research.In case of dispute,the ratio of touch point area shall be the basis for identification.The cast iron surface box is applicable to various inspection operations.It is a datum plane for precision measurement.It should be used for the datum plane in the inspection and measurement of mechanical workpieces to check the dimensional accuracy or action error of parts,and can be used for marking.It is a necessary plane datum measuring tool in the inspection of mechanical manufacturing.The cast iron surface box is a plane reference tool for workpiece detection or marking.The flat plate device shall be adjusted to the horizontal level,the load shall be distributed on each fulcrum,and the oscillation shall be prevented when the ambient temperature is applied.Generally,the service life of the cast iron face box is very long.The cast iron face box only needs to use and maintain the correct method.The precision of the cast iron face box can be used for more than 2 years.The iron plate can be checked for the flatness of the parts by the painting method,which has the advantages of,intuition and convenience.Cast iron surface box is a datum plane used for precision measurement;Inspection and measurement benchmark for machine tools and machinery;Or measure the dimensional accuracy or action error of parts;And draw lines in the mechanical manufacturing.According to its layout,the cast iron surface box is divided into rib plate type and box type,and the rock plate is divided into flange type and non flange type.

Operation,use and maintenance steps of cast iron surface box:

1.When using the cast iron face box,the workpiece should be handled with care,and the rough workpiece should not be moved on the cast iron face box,so as not to cause collision,scratch and other damage to the working surface of the cast iron face box.

2.In order to prevent the overall deformation of the cast iron face box,the workpiece shall be removed from the cast iron face box after use to avoid the deformation of the cast iron face box caused by the heavy pressure of the workpiece on the cast iron face box for a long time.

3.When the cast iron face box is not in use,the working face shall be cleaned in time,then coated with a layer of anti rust oil,and covered with anti rust paper.The cast iron face box shall be covered with the outer package of the cast iron face box to prevent damage to the working face of the cast iron face box caused by carelessness at ordinary times.

4.In order to prevent the deformation of the cast iron face box,when hoisting the cast iron face box,four steel ropes of the same length shall be used to hang the four lifting holes on the cast iron face box at the same time,and the cast iron face box shall be hoisted on the transportation tool stably.

5.The supporting points of the cast iron surface box shall be well padded and leveled.Each supporting point shall be stressed evenly and the whole cast iron surface box shall be stable.

6.During the installation of the cast iron face box,all supporting points of the cast iron face box shall be padded and compacted with adjusting sizing blocks,and the cast iron face box shall be adjusted to qualified accuracy by technicians.

The cast iron face box is composed of face,bond and reinforcement,and each part is cast at one time.The face is also the working face,which is the place where there are many contacts in use.The thickness of the working face is designed according to the load-bearing,accuracy,slotting and other conditions.The thickness of the face is very important,and the use effect should not be too thick,that is to say,it should be achieved;It also involves the enclosure and reinforcement.The enclosure plays a supporting role in use.The thickness and height are related to the supporting capacity of the platform.Generally,the height of the platform is also determined by the size of the platform.The height of the 1500*2000-2000*3000 platform is in the range of 230-300mm,and the height of the platform larger than this specification can be matched to 300-400mm.Too low height will affect the hardness of the platform.The stiffener plays a tensile role,and the height and thickness of the stiffener should be designed according to the load-bearing requirements.The height of the stiffener is usually half,full and flat.

Cast iron surface box material;Cast iron ht200-300 is selected,and the hardness of the working face is hb170-240.After two times of manual treatment(artificial annealing of 600 degrees to 700 degrees and natural aging of 2-3 years),the accuracy of the product is stable and good.The accuracy of the cast iron marking platform of the marking cast iron surface box:according to the standard,the accuracy is 0,1,2 and 3 grades respectively.
