Abstract
Disclosed is a device for producing molded articles, comprising two cross members that are interconnected using tie rods. At least one cross member (11, 12) has an annular section accommodating a pressing module. At least one passage (30) is formed between at least two supporting blocks (3) which allow the distance between the cross members (11, 12) to be adjusted.
Claims17
Device for the production of molded parts, comprising first and second cross members, tie rods, a ring-shaped section, first and second support blocks, and a pressing module,
- wherein said first and second cross members are connected with one another by way of said tie rods,
- wherein said ring-shaped section accommodates said pressing module,
- wherein a first passage is disposed between said first support block and said second support block,
- wherein a distance between said first and second cross members relative to one another can be adjusted via said first support block and via said second support block,
- wherein the device further comprises a tool plate and a hydroforming tool having a compensator for compensation of process-pressure-induced bending of the tool plate,
- wherein the compensator comprises a first compensation plate that can be bent, under hydraulic control, in or counter to the process-pressure-induced bending direction of the tool plate, and
- wherein the first compensation plate has a depression for producing a hydraulic pressure cushion.
Device for the production of molded parts, comprising first and second cross members, tie rods, a ring-shaped section, first and second support blocks, and a pressing module,
- wherein said first and second cross members are connected with one another by way of said tie rods,
- wherein said ring-shaped section accommodates said pressing module,
- wherein a first passage is disposed between said first support block and said second support block,
- wherein a distance between said first and second cross members relative to one another can be adjusted via said first support block and via said second support block,
- wherein the device further comprises a tool plate and a hydroforming tool having a compensator for compensation of process-pressure-induced bending of the tool plate,
- wherein the compensator comprises a first compensation plate that can be bent, under hydraulic control, in or counter to the process-pressure-induced bending direction of the tool plate, and further comprising a first spacer plate, a second spacer plate, and a second compensation plate, the second compensation plate compensating process-pressure-induced bending of the work piece to be formed,
- wherein said second compensation plate is attached on said second spacer plate,
- wherein said second spacer plate lies opposite the first spacer plate and serves for the work piece to lie on,
- wherein the second compensation plate has a side facing away from the second spacer plate and has a first depression on the side facing away from the second spacer plate, and
- wherein a first hydraulic line runs within the second compensation plate and flows into the first depression.
Device for the production of molded parts, comprising first and second cross members, tie rods, a ring-shaped section, first and second support blocks, and a pressing module,
- wherein said first and second cross members are connected with one another by way of said tie rods,
- wherein said ring-shaped section accommodates said pressing module,
- wherein a first passage is disposed between said first support block and said second support block,
- wherein a distance between said first and second cross members relative to one another can be adjusted via said first support block and via said second support block,
- wherein the device further comprises a tool plate and a hydroforming tool having a compensator for compensation of process-pressure-induced bending of the tool plate,
- wherein the compensator comprises a first compensation plate that can be bent, under hydraulic control, in or counter to the process-pressure-induced bending direction of the tool plate, and further comprising a first spacer plate, a second spacer plate, and a second compensation plate, the second compensation plate compensating process-pressure-induced bending of the work piece to be formed,
- wherein said second compensation plate is attached on said second spacer plate,
- wherein said second spacer plate lies opposite the first spacer plate and serves for the work piece to lie on,
- wherein the second compensation plate has a side facing the second spacer plate and has a depression on the side facing the second spacer plate, and
- wherein at least one hydraulic line runs within the second spacer plate and flows into the depression.
