Abstract
The utility model discloses a plastic pipe hot-press apparatus for binding books and data, which is arranged on a punching bookbinding machine, and is mainly composed of a seat, a heat transfer body, a PTCR thermo-sensitive ceramic, a heat insulation cover and a compressing and riveting die. The utility model is characterized in that the heat transfer body is directly connected with the PTCR thermo-sensitive ceramic. The utility model has the advantages of artful conception, reasonable structure, great improvement on insulative safety figure, small influence of the ambient temperature on the heat transfer body, strong stability of softening temperature points of the plastic pipe hot-press and higher industrial utility value.
Description
The utility model relates to a kind of hot-press arrangement, particularly relates to moulding the pipe hot-press arrangement on a kind of perforating binding machine that is used to bind book, data.
The hot pressing riveting die of pipe binder is moulded in the punching of external existing production, all is mounted in the transition body of the heat transmission made from brass, and heating element heater then adopts " fire tube ".To fluctuate in the scope of permission in order making, the control circuit of control " fire tube " temperature rise just must to be set by the thermal softening of compression moulding pipe point.And the temperature control of " fire tube " at present is the principle that adopts bimetal leaf, in measured signal input analog circuit, carries out temperature control.Because the closed temperature of bimetal leaf itself is asynchronous with the temperature rise of break-off signal and " fire tube " heater, will produce bigger difference, influenced the temperature range of softening point permission thus.For this reason, also once the someone to have designed a kind of be the hot-press arrangement of heating element heater with the PTCR thermal sensitive ceramics.But it still adopts the thermal conductor of brass, is separated with mica sheet between thermal conductor and heating element heater.And mica sheet exists the defective that is more easily punctured by higher voltage.Electric shock accidents will take place once breakdown in it.
The purpose of this utility model provides and a kind ofly can effectively overcome above-mentioned defective, and that can improve the insulation safety index moulds the pipe hot-press arrangement.
The technical solution of the utility model is, a kind of pipe hot-press arrangement of moulding mainly is made up of base, thermal conductor, PTCR thermal sensitive ceramics, collet and riveting die, and its characteristics are: thermal conductor directly links to each other with the PTCR thermal sensitive ceramics.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, and is rational in infrastructure, improved the insulation safety index significantly, and thermal conductor is subjected to the influence of environment temperature less, has increased the stability of softening temperature point when moulding pipe hot pressing, the industrial utilization that tool is higher.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, thermal conductor 3 usefulness aluminium oxide ceramics are made, and offer a groove that is " " shape on it, directly be equipped with PTCR thermal sensitive ceramics 4 in the groove of both sides, be connected to power electrode on the PTCR thermal sensitive ceramics 4, thermal conductor 3 mid portions offer a mould installing hole, are equipped with riveting die 1 in this hole.Thermal conductor passes through binding nut 5 for 3 times and links to each other with base 6, the thermal conductor 3 outer collets 2 that are with.
