blanking requires that the plate should have sufficient plasticity to ensure blanking.The plate will not crack when. Soft materials (such as pure aluminum, antirust aluminum, brass, red copper, low carbon steel, etc.) have good blanking performance, and parts with smooth section and small inclination can be obtained after blanking; Hard materials (such as high carbon steel, stainless steel, hard aluminum, ultra hard aluminum, etc.) have poor quality after blanking, and the section roughness is large, especially for thick plates. For brittle materials, tearing is easy to occur after blanking, especially when the width is very small

plates that need to be bent should have sufficient plasticity and low yield limit. Plates with high plasticity are not easy to crack when bending, and plates with low yield limit and low elastic modulus have a wide range of applications, including various stamping, cutting, cutting and other processing technologies, which can be applied to various metal products. For China's machinery manufacturing industry at this stage, sheet metal processing is widely needed, which will promote the development of China's machinery manufacturing industry. Many insights can play a great value, so the market prospect of sheet metal processing is bright. The market potential of sheet metal processing is huge, but it still needs our own efforts to become a leader in the market. Potential alone is not enough. The key is to take practical actions to promote our own development. For this industry, the first thing to do is to improve the processing technology of products as soon as possible and constantly introduce advanced production equipment at home and abroad. We should also strengthen our innovation ability, train a group of scientific researchers, and specialize in sheet metal processing technology and ways to improve product processing performance

Mianyang hardware accessories processing quotation control of inner cavity diameter when the stretching part is circular. When the stretching part is round, in order to ensure the overall stretching quality of the stretching part, it is usually necessary to ensure that the inner cavity diameter ≥ the circular diameter +10 times the plate thickness in the control of the inner cavity diameter. Only in this way can we ensure that there is no wrinkle inside the circular stretching part

Mianyang hardware accessories processing quotation effectively improves production efficiency. The automatic control system can realize the small batch processing of workpieces and the simultaneous processing of different parts, and the processing speed is fast. Because the following problems are reduced: 1. Strengthen the investigation, research and processing of sheet metal parts; 3. The NC integrated processing of the sample without clamping during the test greatly improves the production efficiency, reduces the production cost, and makes it possible to produce hydrogels in an industrial scale

fillet radius control between the bottom of the stretched part and the straight wall. From the standard point of view, the fillet radius of the bottom of the stretched part and the straight wall should be greater than the thickness of the plate. Generally, in the process of processing, in order to ensure the processing quality, the fillet radius of the bottom of the stretched part and the straight wall should be controlled below 8 times the thickness of the plate. The second is to control the fillet radius of the flange and side wall of the stretching part. The fillet radius of the flange and side wall of the stretched part is similar to that of the bottom and straight wall. In terms of fillet radius control, it should be less than 8 times of the thickness of the plate, but in terms of small fillet radius, it must meet the requirements of more than 2 times of the thickness of the plate to open the door from inanimate material to living tissue. The third is to control the diameter of the inner cavity when the drawing part is circular. When the stretching part is round, in order to ensure the overall stretching quality of the stretching part, it is usually necessary to ensure that the inner cavity diameter ≥ the circular diameter +10 times the plate thickness in the control of the inner cavity diameter. Only in this way can we ensure that there is no wrinkle inside the circular stretching part. The fourth is to control the adjacent fillet radius when the stretched part is rectangular

after bending, the springback deformation is small, and it is easy to obtain the bending shape with accurate size. Materials with good plasticity such as low carbon steel, brass and aluminum with carbon content less than 0.2% are easy to bend and form; Materials with greater brittleness, such as phosphor bronze (qsn6.5 ~ 2.5), spring steel (65Mn), hard aluminum, superhard aluminum, etc., must have a larger relative bending radius (r/t) during bending, otherwise it is easy to crack during bending. Special attention should be paid to the selection of hard and soft state of materials, which has a great impact on the bending performance. For many brittle materials, bending will cause fillet cracking or even bending fracture, and for some steel plates with high carbon content, if hard state is selected, bending will also cause fillet cracking or even bending fracture, which should be avoided as far as possible

sheet metal stretching, especially deep stretching, is a difficult kind of sheet metal processing technology. It not only requires the stretching depth to be as small as possible, the shape to be as simple and smooth as possible, but also requires the material to have good plasticity. Otherwise, it is very easy to cause the overall distortion of parts, local wrinkling, and even tensile cracking of stretching parts

high speed cutting. High speed machining technology is a high-tech developed in the 1980s. The important goal is to shorten the cutting and non cutting time during machining, reduce the processing procedures for complex shapes, difficult to machine materials and high hardness materials, and maximize the high precision and high quality of products. Because different machining processes and workpiece materials have different cutting speed ranges, it is difficult to give an exact definition of high-speed machining. At present, it is generally understood that high-speed machining can be considered when the cutting speed reaches 5 ~ 10 times that of ordinary machining

2) high precision machining. High precision machining is the result of the extensive application of high-speed machining technology and CNC machine tools. In the past, the machining accuracy of automotive parts was required to be in the order of 0.01mm. Now, with the increase of computer hard disks, high-precision hydraulic bearings and other precision parts, the accuracy required for finishing has been increased to 0.1 μ m. Machining accuracy has entered the sub micron era

3) compound processing. The compound machining of machine tool is to improve the utilization rate of machine tool by increasing the function of machine tool and reducing the auxiliary process time of multiple clamping, repositioning and tool setting in the process of workpiece processing
