Cet. 13, 1964 F. SPINDLER ETAL 3,152,686
HIGH-SPEED nRAwBENcH Filed March 10, 1961 l United States Patent O 3,152,686 HIGH-SPEED DRAWBENCH Fritz Spindler, Dusseldorf, and Helmuth Wienand, Neuss (Rhine), Germany, assignors to Mannesmann-Meer Aktiengesellschaft, Dusseldorf, Germany, a German company Filed Mar. 10, 1961, Ser. No. 94,808 Claims. (Cl. 20S- 3) This invention relates to drawbenches and, more particularly, to drawbenches for drawing tubes or like articles which may be operated in such a way as to give a high output.
Among the prior forms of drawbrenches is a form in which the carriage runs below a beam. The beam is supported by arms which arch around the carriage from the drawbench frame. Tube discharge skids slope downwardly to discharge the products drawn by the drawbench. However, the costs for construction and materials of this design are too high.
In another prior form of drawbench, the carriage is above the supporting beam and rides on wheels. In order to discharge the tubes, this arrangement requires swinging arms which have to be moved out of the way and returned either by hand or mechanically whenever the carriage passes. The disadvantage of this design is that the operation of these swinging arms prolongs the drawing process considerably.
It is an object of the present invention to eliminate the shortcomings of the prior drawbench designs and to create a drawbench which can be made at minimum cost of construction and materials and which will require only a minimum of operational time.
y According to this invention, the tube discharge skids are located outside the path of the carriage so that the need to move them to let the carriage pass is avoided.
Other objects and advantages of the invention will appear as it is described in connection with the accompanying drawings.
In the drawings:
FIG. l is a side elevation view of a portion of a drawbench embodying the invention.
FIG. 2 is a transverse section view taken along line 2 2 of FIG. 1.
FIG. 3 is a transverse section view similar to FIG. 2, but of another form.
FIG. 4 is a transverse section View similar to FIGS. 2 and 3, but of a third form.
Referring to FIGS. 1 and 2, the drawbench has longitudinally extending frame members in the form of parallel I- beams 10, 12 which are supported along their lengths upon pedestals 14 of any suitable form which rest on the floor and have a at top surface on which the beams are secured. Y
Supported outside the webs of each of the beams 1t), 12 are flat horizontal tracks 16, 18 on which roll carriage wheels 2t), 22. These wheels are mounted on horizontal axles 21, 23 supported respectively in the vertical portions of bent arms 26, 23 extending laterally and downwardly from the carriage chassis 30 which otherwise may be conventionally formed. There is a pair of wheels on each side of the carriage. The carriage chassis is thus supported over and above the beam 10, 12. Side guide plates 25, 27 mounted on axles 21, 23 adjacent the arms 26, 2S slidably engage the side edges of the tracks 16, 18 as the carriage moves along the tracks.
Tubes or other drawn articles are held in jaws 32 of the carriage as the carriage is vdrawn by conventional means along the tracks 16, 18. At the end of the draw when the jaws are opened and the drawn article is released, the article drops down and is deflected laterally with respect to the beam 1d. For that purpose, skid members 34 are secured on top and extend across the beams. Their top surfaces are inclined toward one side of the drawbench and their bottom surfaces rest on the tops of the beams. The skid members may be of any desired width, but preferably are relatively narrow and are spaced closely enough along the beams lil, 12 to provide the needed support and guidance to properly deect the articles as they drop when the drawing is finished.
In FIG. 3 a pair of spaced parallel track 46, 4S are secured upon the top of pedestal supports 40 spaced along the length of the drawbench. The tops of the pedestals are inclined from one side of the drawbench toward the other and have secured thereon sloping skid surfaces 44 also inclined from one side of the bench toward the other so that drawn articles, when released from jaws 55 on termination of the draw, will fall upon and be deflected laterally by the skid surfaces with respect to the length of the drawbench.
Also in FIG. 3, the carriage chassis 50 has two laterally extending axles 51, 53 on each side of which are mounted wheels S2, 54 which ride on the tracks 45, 48.
Since track 48 is at a higher level than track 46, provision is made to keep the carriage on the tracks as it rolls along. For that purpose, one or more arms 56 extend rigidly from the upper side of the chassis over the higher track 48. An axle 57 extendsV downwardly from the end thereof and has a wheel 58 mounted thereon in position to roll along the outer upwardly extending surface of an inverted T-beam 59 or guide-track member whose head is supported upon and secured to the pedestals adjacent the higher wheel track 48.
Against the opposite or inner side of the upwardly extending surface of the T-bearn 59, the end of the axle 53 engages.
In a third form, illustrated in FIG. 4, the pedestals 60 have supported on their horizontal top surfaces one (62) of two parallel horizontal track plates 62 and 64 which are separated by a central web 66 which may be hollow as shown, or it may be solid in case it should be preferred for the plates to be the upper and lower plates of an I-beam.
Between the upper and lower plates, on each side of the central web roll a pair of carriage-guide wheels 7?, 72 whose peripheries preferably are convexly curved, as in the previously described forms. The carriage wheels are supported on horizontal axles mounted in vertical arms or skirts '76, 78 located on opposite sides of the plates 62, 64 and depending from a horizontal trans.- versely extending carriage-supporting plate 77 overlying the upper beam plate 64.
The horizontal carriage-supporting plate 77 is extended laterally beyond one side of the track plate 64. From and beneath this extension 79, the carriage chassis Sti is fixedly supported.
In order to deflect the drawn article when the draw is finished and the article is released from the jaws 82, the pedestal supports are formed with one side or leg 61 inclined downwardly and outwardly under the carriage chassis and the overhanging extension 79.- Thus, as the drawn article drops, it strikes the inclined surface of the leg and is deflected laterally away from the drawbench.
Since the feeding or drawing means, mandrel, dies, gripping jaws per se form no part of the invention, but may be conventional, they need not be further shown or described.
Other modications within the scope of the invention will occur to those skilled in the art. Hence, the invention is not limited to the specific embodiment shown and described.
