Abstract
Description
- The present invention relates to a spiral cramp iron bender, especially to a bender comprising a screw shaft with a plurality of equidistant groove spires on the surface thereof. A cramp iron is guided to the first groove spire forward to the next groove spire around the screw shaft round and round, and bent to a spiral cramp iron with a predetermined thread pitch.
- To manufacture a spiral cramp iron in prior arts, normally a bender bends a cramp iron to a stack of circles, and then the stack of cramp iron is pulled out to a spiral form by manpower in some thread pitch. The pull of manpower is unbalance and unstable, so that the thread pitch of the spiral cramp iron is unequal. The prior arts waste time and manpower, and the quality control of the product cannot be achieved. Moreover, manpower manufacturing often hurts labors and causes damages.
- Some attempts at automatic bender for spring like spiral cramp iron manufacturing were tried in prior arts. However the qualities of thread pitches or lengths control were failed. A better invention is needed for quality and efficiency upgrade.
- To resolve the foregoing defects, the primary object of the present invention is to provide an automatic mass manufacturing spiral cramp iron bender to bend cramp iron into a proper thread pitch and length without manpower.
- Another object of the present invention is to provide a simple structure bender to bend forward cramp iron automatically to a spiral cramp iron with a predetermined thread pitch and length.
- For the aforementioned objects, the present invention is a spiral cramp iron bender comprising:
- a bender body, which comprises a power roller driven directly by power, a driven roller, a transporter, and a shaft bearing for a transmission shaft;
- a transmission shaft, which comprises a connection end for a screw shaft connecting, and the other end of the transmission shaft is set passed through the shaft bearing to roll when power is driving;
- a screw shaft, which comprises a hollow sheath end to connect with the connection end of the transmission shaft, and a plurality of groove spires in a predetermined equidistant thread pitch on the surface thereof;
- wherein a shaft base is set in a position of the bender body corresponding to the shaft bearing for the transmission shaft setting and rolling.
- Wherein the connection end of the transmission shaft can be connected with the hollow sheath end of the screw shaft by screwing, inserting, or welding. The screw shaft is switchable to different standards of thread pitch and circles of groove spires for manufacturing various specific spiral cramp irons when needed.
- With foregoing structure of the present invention, as a cramp iron is transported through the transporter to the bender body, the cramp iron will be guided to the groove spires of screw shaft. The power roller and the driven roller of the bender body guide the cramp iron forward rolling around the rolling screw shaft and along one groove spire to the next groove spire round and round, and finally the cramp iron is automatically bent to a spiral cramp iron with a predetermined thread pitch. The present invention is laborsaving and timesaving for manufacturing spiral cramp iron.

- In the following description of the embodiments of the present invention, please refer to the drawings for further details description.
- As shown in Fig. 1 and Fig. 2, a preferred embodiment of the present invention comprises a
bender body 5, a transmission shaft 6, and ascrew shaft 7, wherein thebender body 5 at least comprises apower roller 53 which is directly driven by power, a driven roller 54 (not shown in Fig. 1 nor Fig. 2, please refer to Fig. 3 and Fig. 4), and a transporter 55 (not shown in Fig. 1 nor Fig. 2, please refer to Fig. 3 and Fig. 4). Thetransporter 55 comprises a plurality of transport rollers 551 (not shown in Fig. 1 nor Fig. 2, please refer to Fig. 3 and Fig. 4), and thebender body 5 further comprises a shaft bearing 51 for the transmission shaft 6 in a proper position, and ashaft base 52 in a position corresponding to the shaft bearing 51. The transmission shaft 6 is passed through the shaft bearing 51 and set on theshaft base 52. - One end of the transmission shaft 6 is a
connection end 61 for thescrew shaft 7 connecting, and the other end of the transmission shaft 6 is passed through the shaft bearing 51 of thebender body 5. The transmission shaft 6 will be rolling when power is driving. - One end of the
screw shaft 7 is ahollow sheath end 71, which is screwed to and welded with theconnection end 61 of the transmission shaft 6. Thescrew shaft 7 also comprises a plurality ofgroove spires 72 with a proper thread pitch "P" on the surface thereof. - Please also refer to Fig. 3 and Fig. 4, a front view and a perspective view of the preferred embodiment of the present invention. A
cramp iron 81 set on a cramp iron base 8 is transported to thebender body 5 by thetransporter 55. Thecramp iron 81 is rolled and transported by thetransport rollers 551 to thegroove spire 72 of thescrew shaft 7. Thepower roller 53 and the drivenroller 54 of thebender body 5 guide thecramp iron 81 forward rolling around the rollingscrew shaft 7 and along thegroove spire 72 to thenext groove spire 72 round and round. Finally thecramp iron 81 is bent to aspiral cramp iron 9 with a proper thread pitch "P" as shown in Fig. 4. - For further illustration, please refer to Fig. 5, a lateral view of the preferred embodiment of the present invention. As the
cramp iron 81 is transported through thetransporter 55 to thebender body 5, thecramp iron 81 will be guided to the first track of thegroove spires 72 ofscrew shaft 7. Thepower roller 53 and the drivenroller 54 of thebender body 5 guide thecramp iron 81 forward rolling around the rollingscrew shaft 7 and along thegroove spire 72 to thenext groove spire 72 round and round. Finally thecramp iron 81 is automatically bent to aspiral cramp iron 9 with a proper thread pitch "P" and a predetermined length (rounds of the spiral cramp iron), and can be mass manufactured without manpower. - The
screw shaft 7 is switchable to different standards of thread pitch and circles of groove spires for manufacturing specificspiral cramp iron 9. - The foregoing describing of the preferred embodiment of the present invention is for the purpose of illustration and description. It is not intended to exhaustive or to limit the present invention to the precise from disclosed. Many other possible modifications and variations can be made without departing from the scope of the present invention, which following claims are depended.
