Description
This utility model is the seamless alloy tooth crown forming machine that belongs to dental.
It is oral cavity a kind of dummy commonly used that hammer is made seamless alloy tooth crown, and traditional forming tool forms former and formpiston with splitting cutter, contoured band, hollow iron prop with acolite, makes dummy through punching press.Conventional art exists formpiston to place and is difficult for guaranteeing that vertically delivery will knock the contoured band edge, and former will divide rives for three times, and
Face and axial plane shaping be the shortcoming of hammering formpiston repeatedly.Chinese patent " improved hard seamless alloy tooth crown hydraulic forming device " (86210314), the seamless alloy tooth crown hydraulic press is set up truncated cone cylinder and truncated cone hole on the punch top, although solved the taking-up of formpiston, there is structure complicated, only be applicable to the deficiency of producing the seamless alloy tooth crown shell by batch.Metal positive perpendicular positioning device, interchangeable three chopper members, screw rod former and adjustable power transmission cover are adopted in the design of this seamless alloy tooth crown forming machine, just can guarantee that the formpiston placement is vertical, screw rod ejects former conveniently, and former can once be split into three equal parts, helps accelerating the seamless alloy tooth crown shaping and improves forming accuracy.
The purpose of this utility model is the deficiency that is to overcome prior art, and operation is simple and reliable to require forming machine, can improve hammer and make precision and the speed that seamless alloy tooth crown is shaped, and will ask for, split mould quick and precisely.
For achieving the above object, this utility model adopts novel formpiston to insert positioner, interchangeable three chopper members, and screw rod former and adjustable power transmission cover member are combined into a novel hammer through design rationally and make the seamless alloy tooth crown forming machine.
Use embodiment below, and in conjunction with the accompanying drawings the project organization of this seamless alloy tooth crown forming machine be described in detail as follows:
Fig. 1 is the plane structure chart of seamless alloy tooth crown forming machine;
Fig. 2 is the A-A sectional structure chart of Fig. 1;
Fig. 3 is the B-B sectional structure chart of Fig. 1;
Fig. 4 is that the C of Fig. 1 is to view;
Fig. 5 is the D sectional structure chart of Fig. 4.
As shown in Figure 1, 2, 3, the seamless alloy tooth crown forming machine is by sliding support, lifting actuator, formpiston inserts positioner, interchangeable three chopper members, screw rod former, adjustable power transmission cover, bedplate and hold-down screw are formed, and it is to compress the location structures that chuck piece 34 is formed formpiston 12 vertical insertion formers 13 with the endoporus clamping formpiston 12 of chuck piece 34 and with screw 33 by spring 32 that described formpiston inserts positioner.Described screw rod former is to be connected with bedplate 17 with die holder 15 respectively with the two ends that die holder connects double-screw bolt 16, and end face contacts with pad 14 and forms the casting and the ejecting structure of former 13.Described interchangeable three chopper members are three the uniform hole clamping choppers 12 in bottom with following 10 of chuck, double-screw bolt is connected outside the lower end at last inner bolt hole and the chuck seat of honour 9, and the trisection that the chuck holder 5 of the chuck seat of honour 9 by chuck linking arm 8 and pin (6,7) and actuating device is rotationally connected form former 13 structure of riving.And adjustable power transmission cover is to push down with formpiston 12 tops with the screw in the screw on the chuck 19 18 to be connected, the side is divided equally screw 33 in three screws and is compressed with the chuck piece 34 of formpiston 12 by spring 32 and be connected, the lower end contacts with former 13 end faces, and the chuck holder 5 of top by chuck linking arm 38 and pin (6,7) and actuating device is rotationally connected and forms the adjustable power transmission nested structure that hammer is made seamless alloy tooth crown.Wherein sliding support is that lower end by front and back slide block post (20,4) is fixed on bedplate 17 left ends with screw 29, fixedly connected with slide block linking arm 3 usefulness screws 21 in the upper end, the two ends of the chute on interior opposite and slide block 31 are slidingly connected, and the left end middle part is composed of a fixed connection with the right-hand member of gear shaft block (22,28).Lifting actuator is by the two ends of slide block 31 and front and back slide block post (20,4) inner face chute is slidingly connected, as Fig. 4, shown in 5, and in the hole, top and the bottom of chute, steel ball 36 is arranged, spring 37 and screw 35 are located by connecting up and down with the locating hole composition at slide block 31 two ends, fixedly connected with tooth bar 2 in middle part, the left side, fixedly connected with chuck holder 5 usefulness screws 30 in middle part, the right side, and by pin 6 and split pin 7 respectively with chuck linking arm (8,38) changeing col connects, gear 1 is fixedlyed connected with gear shaft 26 middle parts and the two ends by gear shaft 26 are bearing in gear shaft block (22 respectively, 28) in the hole, the front end earthing key 25 of gear shaft 26 is fixedlyed connected with handle 24, the front end of the fixed cover 23 on the axle contacts with the back of gear shaft block 22 and tightens up the location with screw 27, thus the lifting drive mechanism that the chuck 19 of the chuck seat of honour 9 of the interchangeable three chopper members of composition drive and adjustable power transmission cover moves up and down.
In a word, connect the seamless alloy tooth crown forming machine that present embodiment manufactures and designs, just can support lifting actuator to move up and down, drive interchangeable three chopper members and adjustable power transmission cover by chuck holder clamp gripper linking arm simultaneously and rotate and move up and down with sliding support.When the casting former, be that metal positive is inserted the perpendicular positioning device, the dissolving acolite is poured in the die holder of screw rod former, then formpiston is vertical inserts in the not solidified former to the required degree of depth, treat to remove the perpendicular positioning device after former solidifies, three choppers can be placed former top, rotation die holder then screw rod ejects the metal former, once former is split into three lobes with the chuck seat of honour end face of hammering hammering three chopper members into shape.Remove three chopper members and rotate die holder again to original position, seamless alloy tooth crown is placed between the yin, yang mould, adjustable power transmission cover contacts with the former end face simultaneously with formpiston on the cover, can make formpiston and former end face simultaneously stressed with hammer hammering chuck end face, realize to the seamless alloy tooth crown of putting into the positive and negative mould carry out axial plane and
The face quick shaping.Simple and the reliable operation of shaped structure of the present utility model, and have put, get formpiston, eject former, rive former and seamless alloy tooth crown are shaped characteristics quick and precisely.
