Definitions
- the present invention relates to presses and more particularly but not exclusively to vertical presses to deform metal sheet.
- a vertical press comprising a frame of generally C-shaped configuration, having a vertically extending main part and two vertically spaced generally horizontally extending arms; a vertical mandrel supported by and extending between the two arms and spaced from said main part; a movable member extending between said arms and located between said main part and said mandrel, said member being movably supported by said arms so as to be horizontally movable toward said mandrel, and means to move said member in a pressing action toward said mandrel, said means including at least two opposing reaction surfaces, one fixed to said main part, and one to said movable member, and a movable wedge located between said surfaces and adapted to operatively engage same to cause movement thereof upon movement of said wedge to thereby cause said movable member to move toward said mandrel in a pressing action.
- the press depicted includes a main frame 10 of generally C-shaped configuration having a main portion 11 which extends generally vertically and two transverse arms 12 and 13, which extend outwardly from the main portion 11.
- the arms 12 and 13 provide supports for a movable member 14 which is slidably guided by the transverse arms 12 and 13.
- Fixed to the extremities of the arms 12 and 13 is a stationary mandrel 15 rotatably supported by the arms 12 and 13 so as to be rotatable about its longitudinal axis by means of a pump and hydraulic motor of which the motor is designated by the numeral 16.
- Located between the main frame portion 11 and the movable member 14 is an arrangement to move the movable member 14 toward the mandrel 15.
- This arrangement includes opposing cam faces 17 and 18 which are slidably engaged by faces 19 and 20 of wedges 21 and 23.
- the wedge 21 is driven upwardly by hydraulic rams 22 while the wedge 23 is moved upwardly by connecting member 24, which extends between the wedges 21 and 23.
- the hydraulic rams 22 are connected to the wedge 21-by means of a pivotable joint 25 while the member 24 abuts the wedges 21 and 23 by pivotable joints 26.
- To retract the movable member 14 there is provided hydraulic rams 27 which abut the wedge 23 also by a pivotable joint 28.
- a former 29 Attached to the leading face of the movable member 14 is a former 29 which is adapted to engage a sheet of metal located in the space 30 defined between the former 29 and mandrel 15.
- the former 29 in combination with the mandrel 15 determines the shape into which the metal sheet will be deformed. For example, if the mandrel 15 is of constant circular cross-section and the former of uniform cross-section then the metal will be deformed so as to form a cylinder. This can be best seen from Figure 3 wherein the mandrel 15 is depicted of a circular cross-section and the former 29 of U-shaped cross-section having leading lugs 31 and 32 depress the metal sheet 33 against the mandrel 15.
- the press is provided with a hydraulic control means which incrementally rotates the mandrel 15 in synchronism with the reciprocating motion of the movable member 14.
- a hydraulic control means which incrementally rotates the mandrel 15 in synchronism with the reciprocating motion of the movable member 14. It should be appreciated that the hydraulic controls could be replaced with electronic controls.
- shape of the mandrel 15 and former 29 may be altered to form objects of different shapes rather than a cylinder, for example - conical shapes, and angled shapes such as squares and rectangles.
- the above described embodiment may be altered to eliminate the need for rams 27 by having rams 22 double acting.
- the support 34 is pivotally attached to arm 13 by means of pin 35.
