Utility model

Device for the gate-like cutting of thermoplastic synthetic foams by means of I filaments "

- There are cutting devices for cutting foam blocks ; known, in which the foam block by adjustable multiple ■ ' Cutting tools is guided and at the same time several cutting edges » ? operations are carried out »

It is more widely known as electrically heated cutting tools

j wires to use «,

; The difficulty in applying this gate devices is "that particular section" t losses and thus spaces between the already geschnit · »f requested block sections occur for cutting foamed materials by means of incandescent filaments"

Is a block of 50 cm height κ, Βο moved horizontally on a Sehiebetisch or on a ■ conveyor belt through a perpendicular to the direction angeord- ^J scribed i "cm" gate 48 horizontally tensioned cutting wires ,, "so cause the above-mentioned cutting losses of about Each Ø ₉ 5 mm; a collapse of the prepared, cut plates by approximately 2.2 cm.

Die8 does not lead to the end of the block to form an undesirable chnittes, 'In order to avoid this phenomenon, the cutting wires hori-: sontalj but vertically tensioned; Thus, the block must be clamped in a guide device, wherein the tensioning device t in turn adjust \ reducing the block thickness after passing through the gate Musso

~ - The case occurring stress causes some foam τ varieties to re-weld or bond behind the cutting wires I '

Ss has now gefund®η _s that the above problems can be eliminated ,; when the cutting wires are arranged next to one another in a preferably horizontal plane at the desired spacing

T and the block to be cut on a plate provided with bars

- is guided through the gate from below »You webs - are like that here

* designed that they each move one

* Support plate section while taking the block through the gate

* Push without touching the cutting wires. "

f ■

The webs must therefore have a different spacing for each panel thickness

'<"habenο The clamping of the block is not necessary» Bs recommends

^y to attach only two supports on the side, a fan-like

\ Prevent the cut slabs of thin thickness from coming apart »

The device is described below with reference to the accompanying drawing

| \ for example described in more detail «

? ' The figure shows:

J A cutter for a 1000 χ 1000 χ 300 mm block cut into

! 50 plates 1000 χ 500 χ 10 ram are to be dismantled,

* 3It show:

i. - «- ■

1 A lifting table that is lifted by the spindle 2 and

* can be lowered.

1 3 An exchangeable multi-skin sheet of 60 mm thickness with 50 over

f \ bars of 5 ™ * thickness and

40 mm high.

I 4 A foam block 1000 χ 1000 χ 500 mm

5 Two side support plates

6 The frame for fastening and tensioning the filaments 7

If the block 4 is pushed against and through the wires 7 by means of the lifting table 1 ■ guidedρ so the webs 3 each support a plate of 10 mm thickness »

- ·] The passage of the wires 7 by the block 4 is also cm at a indulging the wires in the center of the block by the possibility for "B _O 4 with

^r to drive the webs 3 between the filaments 7 ^ secured

The device has been described in one embodiment; at that the block is moved through the gate "

The device can also be built so "that the block with the web" plate is stationary and the gate is moved from top to bottom,

Next is conceivable _t the block between two web plates to hold and guide the gate or the block from the bottom upwards OAER reversed "

Claims (1)

RA. 222 4OW. UO Important for the device is, however, always ₉ that panel to be cut, a support is provided for each, which makes it possible either to cut or to block the plates already cut or Glühdrahtgatter without an additional clamping device for block "or" Plattenstabel. It is also possible to block or gate inclined against each other · "arrange" In this case, the webs must accordingly 'be so high the inclination angle block / gate ₉ that the wires also könaen not enter between the ridges at the top of the inclined plane " Protection claim Device for the gate-like cutting of thermoplastic art » Foams, characterized in that it consists of at least one holding plate provided with webs corresponding to the number of plates to be cut, with the aid of which a foam block is arranged so that either the block or the cutting gate 4tt can be moved against each other, the plates to be cut Do not change their position relative to one another until the cutting tools have completely passed through the block.
