The specific embodiment
Embodiment 1 metal injection moulding green compact automatic chamfering device
Metal injection moulding green compact automatic chamfering device as shown in Figure 3; The positioner group that is provided with a pay-off 1, a guide rail 2 on the frame (not shown) successively, forms by a hold down gag 3 and a postive stop baffle 4, by one have reamer the facing attachment that constitutes of motor 6; And as the motor 7 of its drive unit and a screw rod of transmission device, a conveyer belt 8 is located at the guide rail below.Pay-off has a pellet type structure, have the track that spirals up on it, and inwall has groove.Track ends is tangentially stretched out pallet, joins with guide rail 2.The support holder structure of pay-off below is a dynamic structure, can make support holder structure and on the green compact vibration, and make green compact swash and advance according to the track that spirals.Guide rail 2 is a linear guide rail, and an end that joins with the track ends of pay-off is a near-end, and the other end is a far-end, and far-end also has an inclined-plane outward.Above guide rail 2 far-ends, be provided with the hold down gag 3 that links to each other with detector; Hold down gag 3 is the groove that has Open Side Down by mechanical arm control; The groove inwall just cooperates with the appearance radian of green compact product; The groove two ends are the plane, and when groove inwall and green compact applying, end flat and guide rail 2 are fitted.The drive unit of hold down gag is a motor, and its transmission device is for transferring rotation to straight-line device, like motor screw, crank block or rack-and-pinion etc.On the guide rail 2 distal direction extended lines postive stop baffle 4 is arranged, its be by motor 5 as drive unit, and be connected with a screw rod as transmission device.Postive stop baffle 4 can be along translation before and after the guide rail direction.Have a circular hole and a square hole on the postive stop baffle 4; Wherein the gate location of green compact is consistent on circular hole position and the guide rail; The position of square hole and big I are passed the inclined-plane of guide rail 2 far-ends just; When present dynasty moved to the guide rail direction, postive stop baffle 4 passed the inclined-plane of guide rail 2 far-ends, with the distal face of guide rail 2 and treat that the plane of chamfering green compact fits.Postive stop baffle 4 backs are facing attachment; By one have reamer motor 6 constitute; Reamer diameter on the motor 6 can pass the circular hole on the postive stop baffle 4 just, can drive motor 6 along the front and back translation of guide rail direction as the driving of facing attachment and the motor 7 and the screw rod of transmission device.Present dynasty is when guide rail movement, and the circular hole that reamer can pass on the postive stop baffle 4 carries out chamfering to green compact; When to away from guide rail movement the time, getaway does not influence green compact and advances and fall within on the conveyer belt fully.Conveyer belt 8 is positioned at the below of guide rail 2 distal slope, and its position and size can accurately fall on it the green compact of accomplishing chamfering on the guide rail 2 and passed.
Wherein positioner also can be made as one, and promptly one has the structure of baffle plate of groove and the postive stop baffle 4 of hold down gag 3 simultaneously, and its position can be located on guide rail 2 far-ends tops (being the position of hold down gag 3) or the extended line (being the position of postive stop baffle 4).Positioner also can be divided into the groove of hold down gag 3 left and right sides two parts, and is located at guide rail 2 distal side.Be complementary with injection green compact profile and can green compact be fixed on the guide rail for the positioner of the structure of implementing chamfering as long as have, all belong to and be equal to replacement of the present invention.
Near the motor that has reamer 6, also can be provided with a blow device, it can be fixed on the frame separately or receive the driving of motor 7 equally with motor 6 and move.Said blow device points to green compact cast gate place, when chamfering is carried out or after accomplishing, can clean the cast gate place of green compact.
Also can be provided with a gathering-device at conveyer belt 8 away from a section of guide rail 2, be used to collect the green compact of accomplishing after the chamfering.
The technology of embodiment 2 metal injection moulding green compact chamferings
As shown in Figure 3, at first green compact are put into pay-off 1.Green compact up-down vibration under the power set effect of pay-off 1 is also done to spiral along the track of pallet simultaneously and is moved; When running into the groove of track inwall; Cast gate one side can be passed through at preceding green compact; What direction was not inconsistent then can not fall go back to the tray bottom from track through groove, so green compact will arrange in preceding direction by cast gate one side continuously, and is imported into guide rail 2.Green compact on the guide rail 2 move forward under the promotion of follow-up green compact.When the detector that links to each other with hold down gag 3 detected green compact and puts in place, hold down gag 3 fell under the drive unit effect, and the green compact that will put in place are fixed on the slide rail 2; Motor 5 drives screw rod simultaneously, and postive stop baffle 4 is further pushed green compact in the hold down gag 3, makes its location.The motor 6 that the promotion of motor 7 rotating screw bolts has reamer moves ahead, and motor 6 drives the reamer rotation that configures angle according to the chamfering needs, with near the residue removal the green compact cast gate, and forms chamfering as shown in Figure 1, and the degree of depth of cast gate chamfering is controlled by postive stop baffle.Reamer rotary processing on the green compact 2 seconds (in actual production 2 to 10 seconds all can, look condition such as workpiece, equipment and decide) after, by timing means control, motor 7 screw rods move after driving the device of falling the hole, lift on the while hold down gag 3, move behind the postive stop baffle 4.The postorder green compact will be accomplished green compact and be pushed into forward on the conveyer belt 8 and transport, and accomplish the automatic chamfering processing of green compact.
