Description
Technical field
The utility model relates to a kind of tablet press machine, and particularly a kind of a kind of split type tablet press machine that is used for fields such as medicine, food and chemical industry dashes nail.
Background technology
Use for the industrialization of catalyst, the having relatively high expectations of contrast table area, the more solid catalyst of hollow catalyst not only can increasing specific surface area, reduces cost of manufacture, increases the voidage of catalyst simultaneously, effectively reduces the reactor bed pressure drop.But the hollow catalyst significantly reduces the service life of catalyst because the hollow parts that exists in the middle of it reduces catalyst strength.Tablet press machine is to push towards the nail afterbody by pinch roller, under the traction of guide rail, and upper punch nail and following towards following closely in the hollow mould of middle punch plate correspondence with material extruding becoming cylindrical hollow sheet grain.The nail that dashes that originally uses dashes nail as monoblock type, is the hollow drift at the drift front end, owing to contain metallic element in the catalytic component more, the nail that dashes like this is used for Preparation of Catalyst, the drift top is easier to wearing and tearing occur, in case wherein wearing and tearing appear in certain part, the then whole nail that dashes is promptly scrapped; But if change the nail that dashes of Hardmetal materials entirely into, then dash the section of nailing on and connect tablet machine pinch roller part, very easily cause the tablet machine pinch roller impaired because intensity is too high; Because the mid portion material of catalyst plate grain needs eject from the hollow drift, monoblock type hollow drift is when compressing tablet continuously, and in a single day material sticking phenomenon appears in the hollow drift, and the drift pressurized is excessive in the time of promptly can causing next round compressing tablet, easily causes bursting apart towards ailhead.
Summary of the invention
The purpose of this utility model provides a kind of split type tablet press machine and dashes nail, to overcome the above-mentioned defective that prior art exists.
A kind of split type tablet press machine of the present utility model dashes nail, comprise the upper punch nail and dash nail down, upper punch nail and following structure of dashing nail are split-type structural, described upper punch nail is divided into upper punch nail afterbody and upper punch nail head, upper punch nail afterbody is connected by internal thread with the upper punch nail head, dash under described to follow closely and be divided into down towards following closely afterbody and following, down towards following closely afterbody and being connected by internal thread towards nail head down towards nail head
Between upper punch nail afterbody described in the utility model and the upper punch nail head upper punch langrage spring is arranged, one end of upper punch langrage spring is fixed on the omoplate that give prominence to inside between upper punch nail afterbody and the upper punch nail head, upper punch screw top pin is arranged in the upper punch screw top pin hole of upper punch nail afterbody, the other end of upper punch langrage spring is stuck on the projection of upper punch screw top pin, and upper punch nail head front end is a upper punch; Dash nail afterbody and following down towards having between the nail head under one towards the langrage spring, end towards the langrage spring is fixed on down towards the nail afterbody with down on inner outstanding omoplate between the nail head down, be arranged in towards the screw top pin down and dash the following of nail afterbody down towards the screw top pin hole, the other end towards the langrage spring is stuck in down on the projection of screw top pin down, is low punch towards the nail head front end down.
The operation principle that a kind of split type tablet press machine of the present utility model dashes nail is: catalyst is by upper and lower towards nail, thimble and drift, make catalyst extrude the sheet grain of hollow and annular, the sheet grain of this mesopore ring-type can increase the specific area of catalyst, reduce the beds pressure drop, prolong the service life of catalyst.
Tablet press machine mainly is made up of three punch plates in upper, middle and lower, upper and lower punch plate be equipped with upper and lower dash nail and in the middle punch plate for the intermediate mold of material extrusion modling is provided.Under the effect of pinch roller and guide rail, the upper and lower nail that dashes carries out extrusion modling with material in middle mould, and the centre of upper and lower drift is hollow, and when making the moulding of sheet grain, mid portion is not owing to be stressed, and is extruded during mould in leaving at the upper and lower nail that dashes.Split type spring, the thimble that dashes nail of the utility model promptly can guarantee to dash the continuous operation of following closely with extruding towards nail towards nailing on the adhesion material.
The utility model compared with prior art has the following advantages:
1, upper punch described in the utility model is followed closely afterbody and is carbon steel towards nail afterbody material down, dashing the nail afterbody is contacting with the pinch roller of tablet press machine, can reduce and dash the wearing and tearing of nail the tablet press machine pinch roller, the upper punch nail head is a carbide alloy with descending towards the nail head material, upper and lower is catalyst plate grain moulding part of the force towards nail head, can strengthen the wear-resisting requirement of the raw material of catalyst plate grain to grinding tool.
2, the sheet grain of mesopore ring-type can increase the specific area of catalyst, reduces the beds pressure drop, prolongs the service life of catalyst.
Advantages such as 3, to have a granule strength good for the catalyst of the utility model compacting, and specific area is big.
