Definitions
- the invention relates to a press brake for bending metal sheets.
- a press brake which has a tool manipulation device for taking out individual beer tools from a tool holder of the press brake.
- the tool manipulation device has a slide, which is displaceably mounted on the press brake in a direction parallel to the bending edge.
- On the carriage three manipulation arms are arranged, which are designed to accommodate bending tools. By means of the manipulation arms, individual bending tools can be taken out of the tool holder of the upper press bar, thereby enabling a displacement of the individual bending tools in the tool holder of the upper press bar.
- the press brake described in EP 2 364 789 B1 has the tail, that the tool manipulation device is designed only for receiving three bending tools and thus the flexibility of the tool manipulation device is limited.
- the present invention is based on the object to provide a press brake, in which the tool setup times are as short as possible.
- a press brake is designed for bending metal sheets.
- the press brake comprises a first fixed pressing beam, as well as a second pressing beam displaceable relative thereto; arranged on the press beam or trained tool holders for receiving bending tools; a tool storage for storing unused bending tools; a tool changing device, which is designed for insertion of the bending tools in the tool holder and comprises a gripping device for manipulating the bending tool.
- a tool providing device is formed, which is designed for receiving a plurality of bending tools and which by means of a drive device between a Tooling position, for loading the tool providing device with bending tools from the tool memory, and a tool change position in which the bending tools are transferable by means of the tool changing device from the tool providing device in the tool holder, is displaceable.
- An advantage of the inventive design of the press brake is that the bending tools can be changed in as short a time as possible, so that the set-up of the press brake can be as short as possible and thus the efficiency of the press brake can be as large as possible.
- the transport of the bending tools by means of the tool supply device, that the bending tools can be used with a simple as possible tool changing device in the tool holders of the pressing bars.
- a tool carrier is formed which is designed to accommodate at least two bending tools simultaneously, wherein the tool carrier can be coupled to the tool providing device and can be accommodated thereon.
- the advantage here is that a plurality of bending tools can be used in the tooling position in the tool carrier and for this placement process, the tool delivery device need not be positioned in the tooling position. After the assembly process of the tool carrier with bending tools, the tool carrier can be picked up by the tool supply device and transported by the latter into the tool changing position.
- a first linear guide is formed, which is arranged on an inner side of the first pressing beam
- second linear guide is formed, which is arranged on an outer side of the first pressing beam
- the tool providing device has a portal which the tool holder of spans the first beam and at which portal a first guide unit of the first linear guide and a second guide unit of the second linear guide is arranged, whereby the tool supply device is parallel to a bending edge displaceable.
- the drive device comprises a toothed rack, which is arranged on the first pressing beam, wherein a pinion which is coupled to a arranged on the tool providing device positioning motor engages the rack, whereby the tool providing device is displaceable parallel to a bending edge.
- the toothed rack is arranged on the outside of the first pressing beam. This positioning of the rack can be selected in order to integrate them as well as possible in the bending press.
- a manipulation device is formed, which is arranged in the region of the tool storage and for manipulating the bending tools and / or the tool carrier between tool storage and tool supply device is used.
- the advantage here is that the bending tools can be transported in the tool storage by means of the manipulation device of the space provided for the bending tools storage space in the tool delivery device or in the tool carrier.
- the manipulation device may have a first manipulation arm and a second manipulation arm, a first coupling device being formed on the first manipulation arm and a second coupling device for receiving the tool carrier or the bending tools on the second manipulation arm. Due to the two manipulation arms of the manipulation device, two of the tool carriers can be received by the manipulation device, whereby it is possible for the manipulation device in one working step to have a tool carrier located in the tool change position on the first manipulation arm of the manipulation device. tion is taken and on the second manipulation of the manipulation device already a second tool carrier is prepared to be equipped with bending tools in order to use it as quickly as possible in the tool change position can.
- both manipulation arms have a linear adjustment, by means of which the two coupling devices are independently displaceable in the vertical direction.
- the advantage here is that the tool holder can be used by this measure in the vertical direction in the tool change position or in the tooling position.
- a specific movement of the tool carrier can be achieved by the independent displacement of the coupling devices in order to use the tool carrier in the tool change position or in the tooling position even in tight conditions.
- the tool supply device has a first tool receiving area, which serves for receiving bending tools for the first stationary pressing beam and has a second tool receiving area, which serves for receiving bending tools for the displaceable second pressing beam.
- the advantage here is that at the same time bending tools can be accommodated in the tool delivery device both in the first tool receiving area and in the second tool receiving area. Thereby, the performance of the tool changing device can be increased.
- Blecheinschubtiefe backgauge device serves as a tool changing device for inserting the bending tools in the tool holder.
- the advantage here is that the backgauge device which is present on the press brake anyway can be used simultaneously as a tool changing device and thereby the total cost of the press brake can be kept as low as possible.
