Abstract

The utility model discloses a structure for connecting a fly wheel and a screw stem of a spindle press. The structure is characterized by comprising a central sleeve and an inner sleeve, wherein one end of the screw stem is connected with the central sleeve; the fly wheel is connected with the inner sleeve; the inner sleeve is contacted with the central sleeve; the contact surface is in a toothed structure; the inner sleeve and the central sleeve can relatively slide in the axial direction of the screw stem; the other end of the screw stem is fixedly connected with a slide block; the middle part of the screw stem is connected with a nut; and the nut is fixedly connected with a machine body. The structure has the advantages of realizing torque transfer of the fly wheel and the screw stem in the rotation direction and realizing bidirectional linear movement of the screw stem along the axis of the screw stem.

Description

A kind ofly be used for the structure that the fly press flywheel is connected with screw rod
Technical field
The utility model relates to the fly press in the metal forming machinery, specifically refers to a kind of structure that the fly press flywheel is connected with screw rod that is used for.
Background technology
In existing double disk friction screw press and fly press, screw rod rotation under flywheel drives, because the spiral of screw rod and nut relation, rotatablely moving of screw rod is created in the rectilinear motion of screw axis direction.Being connected between original flywheel and the screw rod is fixedly connected, and flywheel and screw rod are together done along the rectilinear motion of screw axis direction.
Summary of the invention
The utility model has solved screw rod and carried out the problem that straight line moves along the screw axis direction in the flywheel driven rotary.Be particularly suitable for original double disk friction screw press is transformed.
The utility model is implemented by the following technical programs:
A kind ofly be used for the structure that the fly press flywheel is connected with screw rod, it is characterized in that: this structure comprises center and interior cover, wherein screw rod one end connects center, cover in flywheel connects, interior cover and center contact, contact surface is a tooth-shape structure, and interior cover can be done relative slip along screw axial with center; The screw rod other end is fixedlyed connected with slide block, and the screw rod middle part is connected with nut, and nut is fixedlyed connected with fuselage.
Between screw rod and the nut for being threaded.
The tooth-shape structure number of interior cover and center contact-making surface is 1,2 or a plurality of.
The format surface of the contact-making surface of interior cover and center is the plane.
The format surface of the contact-making surface of interior cover and center is an involute profile.
Advantage of the present utility model is to realize that flywheel and screw rod upload torque delivery in direction of rotation, can realize that again screw rod moves at the two-way linear of its axis direction.

Description of reference numerals:
Flywheel, 2. screw rod, 3. nut, 4. fuselage, 5. slide block, 6. in cover, 7. center.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the structural representation of fly press in the prior art, and as shown in the figure, in existing fly press, screw rod 2 one ends are fixedlyed connected with flywheel 1, and power set drive flywheel 1 and rotate, and flywheel 1 drives screw rod 2 and rotates; Screw rod 2 other ends are fixedlyed connected with slide block 5, between screw rod 2 middle parts and the nut 3 for being threaded.
Fig. 2 is interior cover and center front view, Fig. 3 is interior cover and center vertical view, as shown in the figure, after adding mainly the flywheel of forming by interior cover and center and screw rod syndeton, formation is the center with screw rod 2, be followed successively by the structure of center 6, interior cover 7 and flywheel 1 from inside to outside, cover 6 is connected with flywheel 1 wherein, center 7 is connected with screw rod 2, interior cover 6 and center 7 rely on two identical tooth-shape structures contacts, in the moment of torsion that transmits from flywheel 1, cover 6 and center 7 relatively moves in realizing.Arrow is depicted as linear movement direction among Fig. 2.Embodiment is selected 2 tooth-shape structures for use among the figure, in actual applications, can select one or more tooth-shape structures to connect according to field erected needs.
The utility model irrotationality is used flywheel 1 of the present utility model can drive screw rod 2 and is done forward, reverse two-way rotation to requiring.Flywheel 1 drives center 7 by interior cover 6, and center 7 drives screw rod 2 rotations.When flywheel 1 was rotated in the forward with reverse rotation, the surface texture that interior cover 6 contacts with center 7 can both transmit moment of torsion.Because being threaded between screw rod 2 and the nut 3, make the rotation of screw rod 2 change the rectilinear motion of screw rod 2 into along its axis direction, thereby driving slide block 5 moves up and down, finish extrusion operation, can realize that flywheel 1 and screw rod 2 upload torque delivery in direction of rotation, can realize that again screw rod 2 moves at the two-way linear of its axis direction.Nut 3 is fixedlyed connected with fuselage 4.
The interior cover 6 of the utility model example in Fig. 2,3 can be plane or involute profile with the variation that center 7 is transmitted the contact-making surface of moment of torsion, also can be the form that the plane combines with involute profile.Arrow is depicted as linear movement direction among Fig. 2, and arrow is depicted as the direction that rotatablely moves among Fig. 3.
In the practical application, interior cover 6 can be to overlap 6 in the processing separately outside flywheel 1 with the connected mode of flywheel 1, be connected with flywheel 1 then, also can be that interior cover 6 and flywheel 1 are merged into a part, cover 6 be used for tooth-shape structure and the contact-making surface with center 7 transmission moments of torsion promptly directly processing on flywheel 1 in.
The connected mode of center 7 and screw rod 2 can be a machining center cover 7 separately outside screw rod 2, be connected with screw rod 2 then, also center 7 and screw rod 2 can be merged into a part, promptly on screw rod 2, directly process center 7 be used for interior cover 6 transmit moments of torsion tooth-shape structure and contact-making surface.
