Filed: 1975-09-25
Abstract: 1493898 Chucks FRIEDKICH DECKEL AG 25 Sept 1975 [23 Oct 1974] 39411/75 Heading B3B A tool chucking device comprises a hollow spindle 12, an axially displaceable draw bar carrying a coupling head 22 adapted to positively engage and release a tool shank 16 having an externally grooved profile 18, wherein the coupling head is constituted by a slotted resiliently expandable bush means having a complementary grooved internal profile 24 to engage the tool shank, and means are provided for expanding the slotted bush means during its axial displacement in a tool ejecting direction for the purpose of releasing the tool shank. Initial ejecting movement moves the head 22 until tapered shoulder 40 clears the end of a sleeve 32, during which time the shank is still positively locked to the draw bar. During further ejecting movement a cross pin 30 acts between a pair of jaws 26, 28 formed in the head 22 to force them apart to release the shank 16. The sleeve 32 is movable against a spring 44 a distance equal to at least one pitch of the thread or grooves, so that if crest-to-crest engagement occurs during clamping of a shank 16, the head 22 engages the sleeve 32 and retracts it until form locking engagement occurs. The grooves 18, 24, may be a screw thread, or a series of grooves or collars. A spring loaded pin 52 prevents wedging of a shank taper in the spindle socket on initial engagement, until finally pulled therein by the draw bar. The draw bar as described, is biased by springs to a tool clamping position.

Hydraulic cylinders 1, 2, 11<SP>1</SP>, 11<SP>11</SP> and pistons 3, 4, 17, 16, for moving an injection plunger or screw 31 and an injection cylinder 12 are arranged concentrically about support bars 3<SP>1</SP>, 4<SP>1</SP> on which the plunger or screw and cylinder are supported. The pistons 3, 4 are fixed on the support bars 3<SP>1</SP>, 4<SP>1</SP> but the pistons 16, 17 are slidable thereon. Pistons 16, 17 are connected to cylinders 1, 2, respectively, by connecting- rods 25, (25<SP>1</SP>) and 26, (26<SP>1</SP>). In operation a valve 8 is operated by a solenoid so that fluid is supplied from P through B, a conduit 6 and throttle valve 29 to a motor 10 to drive the screw 31. Fluid also flows to chambers 33, 34, causing the return travel (to the right) of cylinders 1, 2 and pistons 16, 17 connected thereto. The outflow from chambers 14, 15 is impeded by a regulating valve 19. The return movement of pistons 16, 17 causes return movement of the cylinders 11<SP>11</SP>, 11<SP>1</SP>. Injection material fed forwardly by the screw 31 is held under pressure in the forward end of the cylinder 12. Valve 8 is then changed over so that screw 31 stops and fluid from P is fed through A, conduit 7 and branch 7<SP>1</SP> into chambers 32, 35 of cylinders 1, 2. This causes the screw 31 and injection cylinder 12 to move to the left. Chambers 14, 15 are fed with fluid at the same pressure as chambers 32, 35 through a one-way valve 24. When the injection nozzle 13 contacts the mould the nozzle is opened and the resultant forward movement of pistons 16, 17 and cylinders 1, 2 moves the screw 31 forwards so as to effect injection.
