Aluminum veneer cutting device
Technical Field
The invention relates to the field of aluminum veneer processing equipment, in particular to an aluminum veneer cutting device.
Background
The aluminum veneer is a building decoration material which is processed and formed by adopting fluorocarbon spraying technology after chromizing and other treatments. The fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt mist and various air pollutants, has excellent cold and heat resistance, can resist the irradiation of strong ultraviolet rays, can keep colorfast and not chalking for a long time, and has long service life. The aluminum veneer mainly comprises a panel, reinforcing ribs, corner connectors and other parts.
In the production process of the aluminum veneer, the aluminum plate (plate) is usually large in size and needs to be cut according to the size of the finished aluminum veneer. Among the prior art, a cutting equipment for cutting aluminum plate needs to press from both sides tight and location with aluminum plate before carrying out the cutting of aluminum plate to make things convenient for the cutting knife cutting.
However, for the same batch of sheet materials, different slits are usually required to be processed on the sheet materials according to the size of the finished aluminum veneer (i.e. the positions of the slits on the sheet materials need to be adjusted). But under the condition that the cutting knife is not moved, the positioning precision of the plate is particularly important to ensure that a new cutting slot to be cut is aligned with the cutting knife (the cutter slot). At present, a servo motor positioning mode is used for pushing a plate to move accurately for positioning, but the mode has the problem of high use and maintenance cost. The invention provides a low-cost aluminum veneer cutting device aiming at the condition that aluminum plate cutting is usually mass production and can be processed for a long time by once adjusting and positioning, thereby solving the problem of how to position a plate under the condition that the position of a cutting seam needs to be changed.
