                                    Feature of SPL straightener It is updated product of H series straightener specially designed for punching super thin products. As we all know, coil material can not produce good products without flattening and stress relieving treatments; therefore, the performance of the straightener is critical in the production process. The flattening and the straightening secondary wheels adopt imported SUJ2, milling after HRC60°heat treatment and starts production after plating the hard chrome to ensure the evenness of the chrome layers and the form tolerances of each bearing. The flattening adjusting adopts the floating four-point balancing equipment, with the dial indicator which can find the leveling point rapidly. The transmission wheel adopts the compelled cycling immersion oil lubrication to reduce the wheel abrasion and be able to work under the high temperature condition for a long time. Adopts the synchronous transmission structure to transfer each leveling roller individually to lower the panel surface flatness improving requirement because of the interspaces caused by wheels rotating. The additional lubricating system prolonged the machine life span and enables it to work under the stable condition in a long time. Due to the differences of the material quality width and thickness, there are no fixed values as the preferences; therefore, taking some material for pilot run before the mass production and start the continuous assembly after it reaches the standard.

Spiral duct machine, also called spiral tube machines are utilized as manufacturing systems for producing rigid spiral metal pipes. Automated spiral duct machines are used in the mass production of custom and standard size spiral pipes, are employed in large industrial organizations as well as custom and small job-shop organizations. Many C&U type forming machines have integrated CNC controls to manufacture custom diameters and lengths from pre-programmed g-code. Some spiral duct machines utilize special interchangeable dies and feed mechanisms that define the as-manufactured duct diameter and shape. Shapes that can be manufactured are : square, rectangle, round, oval, conical and any combination with a capable machine.

Feature of JHL metal sheet strip straightener This is a special designed straightener for the connectors that need high precision. The flattening and the straightening secondary wheels adopt the imported SUJ2 and the HRC60 heat treatment, starts production after plating the hard chrome and then milling to ensure the evenness of the chrome layers and the form tolerances of each bearing. The flattening adjusting adopts the single point balancing equipment, with the inedex ring, which can find the leveling point rapidly. Except the straightening roller the additional feeding wheel improves the material punching precision. Adopt the high precision wheels to prolong the operation time, and the frequency converter can be chosen according to the customer requirement, which enables the special material panel straightening more competitive.

Feature of SSP metal sheet strip straightener S shape high speed straightener is necessary equipment for press machine synchronous feeding, feeding speed is controlled by frequency convertor, material enter press through buffer ring track. Material feeding start/stop and feeding speed are control by photoelectric switch instruction, in order to obtain the same speed as the press machine. This series straightener is upgrade version of the S series straightener. Special designed for thin materials that need high precision punching treatment. As we all know, coil materials can not produce good products without the flattening and stress relieving treatments; therefore, the performance of the straightener is critical in the production process.

Due to the differences of the material quality, width and thickness, there are no fixed values as the preferences; therefore, taking some materials for pilot run before the mass production and start the continuous assembly after it reaches the standard. In order to lubricate easier, we put the gear box out of the machine body. By this way can ensure the operators’ safety.

One of the primary applications of motoring machines today are seen in the form of the roll feeder machines, a set of contemporary basics that work together to provide feeding action to a press. While on the one hand these are used collectively for many kinds of feeding actions, they are often applied to matrix based systems as well. The most familiar method of feeding a press is offered by a roll feeder. To provide a fixed 180 degree angle, the adjustable eccentric is mounted to the end of the crankshaft. The one-way clutch connected to the eccentric feeds the stock while feed rolls clamp the material

Variations in the handling capacities of metal sheets have become quite commonplace considering the sheer volume and nature of work that goes on in the industry today. As a result, many users are now focussing on specific aspects of the process and looking for a particular quality to be enhanced during operation. Precision straightener for stainless steel is suited for thin stainless sheet steel, copper sheet, iron sheet and aluminium sheet etc. It is specialized for straightening. SUJ2 materials are adopted by the straightening rollers with an annealing treatment and hard chrome plated. Spots fine adjustment and a reference digital are adopted, which can level the material rapidly. Auxiliary wheel are also there in addition to the up and down straightening rolls as this design can reduce the stress of the straightening rollers and lengthen the lifetime. Power loss is reduced due to the up-down all gear system and cutting the material is avoided. The lubricating system makes it serve a longer time and be in a precise working state.

Die clearance too small- Clearance can be proper clearance or tight clearance. In proper clearance fracture lines meet, punching forces are balanced. In general, shear strength determines clearance (10% is good for low shear strength aluminium). The recommended minimum die clearance is 0.08mm. In tight clearance fracture lines do not meet, secondary shear cracks, extra energy is required and involves higher tool wear. Poor or no maintenance on the tool- Proper tool maintenance results in flatter sheets, cleaner holes, less stress on tool and machine, longer tool life and maxima coating is not affected. To maximize tool life sharpen frequently, use proper die clearance and shear configuration, lubricate punch, guide and sheet, inspect tool holders for wear, treated tools should be used for special applications, radii should be used on all sharp corners, turret alignment should be checked regularly. Turret alignment requires adjustment- Thick turret alignment tools include mate pilot alignment system, standard alignment tool.

Carrying forward the traditional development of feeders based on people's needs and their area of application, there are many ways in which the pneumatic feeder surpasses its predecessors on accuracy, precision and speed. If mentioned separately, these are ideal for applications that require on the loop control. The 'pneumatic' feeder and its subsequent hydraulic version, using 'orbital motors' are its most important and innovative automation systems for press feeding in the automotive sector, and are chosen by major companies (OEMs) such as Alfa Romeo. Pneumatic feeders meet new competitive challenges in speed, accuracy, reliability, longer life with an intense market research and practical experience in metal stamping based on regular market interaction and suit exact requirement and application of the user . There are various kinds of pneumatic feeders available in the market like industrial pneumatic feeder , compact pneumatic feeder, heavy duty pneumatic feeder , roll band feeder , pneumatic thin strip feeder.

The central hole of the main structure is by lapped finishing first and then electroplating so as to better ensure its roundness and straightness, which thus enables the core shaft to run smoothly. After processed, the main structure goes through anti-corrosive treatment, and then it is cleaned through ultrasonic wave before assembled so as to guarantee trouble-free when processing leftover materials. The exchangeable reversal valve is constructed large circular angle and its internal bore goes through mirror polishing treatment so as to greatly improve feeder’s loading speed and the life span of sealing ring. All the sealing parts are introduced from Japan.
