Abstract
The invention relates to an application of micro-connection in metal plate arc bending. The consistency of the entire arc surface of a work piece is hard to guarante due to vacant portions in the bending work piece in the prior art. According to the micro-connection, the characteristics of laser such as thin kerf and high precision are utilized, the shape of the bending work piece to be bent can be cut at one time, portions need to be removed can be used as auxiliary materials and reserved in advance in the micro-connection mode, and the auxiliary materials are removed after the work piece is bent. The application of the micro-connection in the metal plate arc bending has the advantages that the micro-connection mode can ensure that the stress of each bending of bending equipment and the bending work piece is consistent and uniform, the radian after the work piece is bent is consistent and beautiful, reject ratio of products is reduced, and production efficiency is improved.
Description
Technical field
The present invention relates to the panel beating technology in a kind of machining, particularly relate to the panel beating circular arc bending technology in panel beating.
Background technology
Common technique is exactly after the sheet metal blanking, carries out bending by bending equipment.Traditional bending equipment is that bending workpieces is placed on bending lower die, when bending, bending tool (patrix) is imposed in the ambient pressure situation, makes the bending workpieces matrix material produce distortion cutter one cutter and forms certain angle of bend, thereby realizing forming parts.
Prior art in process of production, often need bending hundreds of cutter in bending circular arc process, if being a centre, bending workpieces has vacant position partly, the operator is when the operation bending equipment, sheet material is because unbalance stress can stay impression at surface of the work, and an end warpage, relies on the personal work experience, an end in buckling deformation returns cutter, is difficult to guarantee that the whole face of workpiece circular arc is consistent.Therefore, when guaranteeing the bending equipment bending and the stressed of surface of the work be evenly the key link that affects the bending quality, be also urgent problem in production process.
Summary of the invention
In order to overcome the deficiencies in the prior art, be intended to propose a kind of simple in structure, operation and maintenance is all very convenient, can effectively guarantee bending equipment and be kept stressed by the bending workpieces surface and evenly improve the bending quality, and the duty because of the operator does not change.Providing a kind of little connected mode technical scheme to be applied in panel beating circular arc bending technique is purpose of the present invention.
Technical scheme of the present invention is to come specific implementation by following technical measures, a kind of little application that is connected in the bending of panel beating circular arc, it is characterized in that: this little connection is to utilize the joint-cutting of laser thin, the characteristics that precision is high, once the shape that needs bending workpieces is completed in cutting, with the former part of need removing as auxiliary material, employing first retains with the form of little connection, make the workpiece that needs bending be still the sheet material of complete shape, remove auxiliary material after bending, according to the little connecting portion of bending workpieces true form cutting.
Described former bending workpieces material and connecting by little connection between the auxiliary material of removing after bending.Make bending tool apply slight pressure to product under the hundreds of cutter effect of bending, the stressed uniformity of each cutter bending guarantees that bending workpieces two ends radian in the bending and molding process is consistent, attractive in appearance.
The two ends of such sheet material are stressed consistent when the bending circular arc, and guarantee the stressed consistent of each cutter bending, after completing bending and reaching technological requirement, cut off little connection, remove the former part that needs removal, complete product Bending Processing task.
The width B of described each little connection equals 0.5-1.0 times of material thickness, and the length L of little connection is 5-15mm, and spacing H is 80-160mm.
Good effect of the present invention is that this little connected mode can guarantee bending equipment and the every cutter bending of bending workpieces (particularly asymmetric, jaggy bending workpieces) stressed consistent evenly, after bending, radian is unanimously attractive in appearance, avoid workpiece unbalance stress one end in two ends when bending to produce warpage, need the workman to return the cutter shaping according to the personal experience, reduced the fraction defective of product, reduce the scrappage of doing over again, improved production efficiency.
Description of drawings
Fig. 1 is the structural representation after the bending workpieces bending and molding.
Fig. 2 is the side view of Fig. 1.
Fig. 3 treats the bending workpieces schematic diagram.
Fig. 4 is the local enlarged diagram of little connection.
The meaning that in accompanying drawing, each legend mark is expressed as follows respectively:
1, bending workpieces; 2, little connection; 3, the auxiliary material of removing after bending; L, little connecting length; B, little connection width; H, little connection spacing.
The specific embodiment
Below we use this little connection with the example of being connected by reference to the accompanying drawings and are described in further detail, in the hope of set forth its structure and occupation mode more clearly.
The present embodiment is a long 2180.5mm, wide 665.3mm, and the aluminium sheet of thick 3mm has the T v notch v at an end of bending workpieces, requires this irregular another part circular arc is bent into a watt shape.As scheme to adopt little connected mode, described little connected mode comprises former bending workpieces material 1, is connected with the auxiliary material 3 of removing after bending by little connection 2, described former bending workpieces material 1 directly all is not connected with the auxiliary material 3 of removing after bending, and little connection just is spaced a distance.
Described former bending workpieces material 1 trade mark is that AL1050 thickness is the 3mm raw material.
Described little connection 2, length L are that 10mm, width B are that 2.5mm, spacing H are 100mm.
The described auxiliary material of removing after bending 3 is for to cut according to the product true form.
Described former part material 1 and connecting by little connection 2 between the auxiliary material 3 of removing after bending.In bending 180 cutter processes, make Bending Mould apply slight pressure to product, the stressed uniformity of each cutter guarantees that part two ends radian in the bending and molding process is consistent, attractive in appearance.
According to technique scheme, this little connected mode can be guaranteed the stressed consistent even of the every cutter bending of bending equipment and workpiece, after bending, radian is unanimously attractive in appearance, avoid workpiece unbalance stress one end in two ends when bending to produce warpage, need the workman to return the cutter shaping according to the personal experience, reduce the fraction defective of product, reduced the scrappage of doing over again, improved production efficiency.
