Definitions
- the innovation relates to a device for producing pressed molded parts or the like, with a press, a loading and an emptying device, wherein a loading arm driven by a displacement drive and an emptying arm driven by a displacement drive are used for press loading.
- the loading arm and the emptying arm are each driven by an electromotive displacement drive.
- Such a shifting drive which has to accelerate the loading or unloading arm twice from standstill to the maximum speed and has to decelerate two times from the maximum speed to standstill during a press cycle, is however only suitable for relatively low shifting speeds because of its large flywheel mass.
- the innovation is based on the task of creating a sliding drive for the loading arm and the emptying arm, which enables a short loading and emptying time for the press.
- each displacement drive for the loading or unloading arm consists of at least two lifting cylinders, the stroke lengths of which are shorter than the displacement path of the loading or unloading arm.
- two pushing devices for holding the loading or unloading arm in the end positions of the shifting path are assigned to each shifting drive.
- Each pressure device has a pressure cylinder and a pressure lever.
- Each pressure lever has a pressure roller.
- Each lifting cylinder is expediently a pneumatic cylinder.
- a device 1 for producing pressed molded parts contains a hydraulic press 2, a loading device 3 and an emptying device 4.
- the hydraulic press 2 has a press frame 5, the lower crossmember 6 of which carries a lower mold 7.
- An upper molding tool 9 is fastened to a displaceable press crossmember 8.
- the displaceable press crossmember 8 is driven by a press cylinder 10.
- the loading device 3 and the emptying device 4 each have a boom 11, 12 fastened to the press frame 5, a column 13, 14 which can be raised and lowered and a guide bracket 15, 16.
- the column 13 of the loading device 3 is firmly connected to the guide carrier 15, the column 14 of the emptying device 4 to the guide carrier 16.
- each column 13, 14 generates a geared motor 17, 18 via a pinion (not shown) and a rack 19, 20.
- the guide carrier 15 serves for the horizontal guidance of a loading arm 21 and for receiving a displacement drive 22 for the loading arm 21.
- a gripping device 23 is arranged on the loading arm 21 for gripping and depositing material 24 to be pressed.
- the guide support 16 is used for the horizontal guidance of an emptying arm 25 and for receiving a displacement drive 26 for the emptying arm 25.
- a gripping device 27 is arranged on the emptying arm 25 for gripping and depositing a pressed molded part 28.
- the guide supports 15, 16 are of completely identical design, as are the loading arm 21 and the emptying arm 25, as well as the displacement drives 22, 26.
- Each guide carrier 15, 16 has eight guide rollers 29, 30, 31, 32, 33, 34, 35, 36 with a horizontal axis of rotation and four guide rollers 37, 38, 39, 40 with a vertical axis of rotation.
- the loading arm 21 and the emptying arm 25 are each composed of three square tubes 41, 42, 43 and two end pieces 44, 45.
- Each displacement drive 22, 26 consists of four lifting cylinders 46, 47, 48, 49, the stroke lengths 50, 51 52, 53 of which are shorter than the displacement path 54, 55 of the loading arm 21 or emptying arm 25.
- the lifting cylinders 46 to 49 are completely identical pneumatic cylinders.
- Each pushing drive 22, 26 is assigned two pressing devices 56, 57 for holding the loading arm 21 or emptying arm 25 in the end positions 58, 59, 60, 61.
- Each pressure device 56, 57 contains a pressure cylinder 62, 63, a pressure lever 64, 65 and a pressure roller 66, 67.
- the pressed material 24 lying on a frame 68 is gripped by the gripping device 23 and the pressure roller 67 is pivoted away from the end piece 45 of the loading arm 21.
- the geared motor 17 is switched on, which causes the column 13, the guide carrier 15, the gripping device 23 and the pressed material 24 to be raised by a dimension 69.
- the loading arm 21 is accelerated by the lifting cylinders 47, 49 on the stroke length 51, 53 from standstill to a shifting speed V 1. Because of the friction between the guide beam 15 and the loading arm 21, the displacement speed V 1 in the displacement area 70 drops slightly to a displacement speed V 2.
- the pressure roller 66 is pressed against the end piece 44 by actuating the pressure cylinder 62.
- the loading arm 21 is now held in a certain horizontal position by pressing the pressure roller 67 against the end piece 45.
- the pressed material 24 placed on the lower mold 7 is pressed downward into a molded part by moving the upper mold 9 downwards.
- the pressed molded part is then transported with the emptying device 4 from the lower mold 7 to a frame 71 with the press 2 open.
