Description

Full-automatic galvanized sheet air pipe continuous production line and production process

Technical Field

The invention relates to the technical field of automatic production lines of air pipes, in particular to a full-automatic galvanized sheet air pipe continuous production line and a production process.

Background

The air duct is a duct system for conveying and distributing air. There are two kinds of composite air pipe and inorganic air pipe. Composite air ducts are represented by the Durkduct air duct. They can be classified according to their sectional shapes and materials. The air duct is manufactured by coating sealing neutral glass cement on gaps such as seaming gaps, rivet gaps, four corners of flange turnups and the like. Before the sealant is coated, dust and oil stains on the surface are removed. According to the cross-sectional shape, the air pipe can be divided into a plurality of circular rubber (such as an air pipe, a rectangular air pipe, a flat circular air pipe and the like, wherein the circular air pipe has the smallest resistance but the largest height dimension, and is complex to manufacture.

The metal air duct is an air duct made of various metal materials, and commonly used metal materials include galvanized iron sheets, stainless steel and the like. The common-plate type flange air pipe is also called a flangeless air pipe, and the manufacturing form of the common-plate type flange air pipe is faster, more convenient and smaller in air leakage rate than the traditional rectangular air pipe. Its advantages are saving material and reducing investment in engineering; the air leakage rate is small, the energy consumption is reduced, the operation cost is saved, and the air leakage rate is quite popular with plant decoration construction enterprises. The standard straight pipe is directly pressed into a connected flange on a production line. And (3) finishing the TDF flange forming on single equipment after blanking of the nonstandard straight pipe, the elbow, the tee joint, the four-way joint, the accessories and the like. The flange angle is by the direct stamping forming of mould, the card during installation can at four angles. The flange clamp for connecting the flanges is made of galvanized steel plates, and is formed by a flange clamp forming machine and then cut into uniform sizes for installation and connection. TDF common plate flanges are connected with pipeline steel plates into a whole, punching and riveting are not needed like angle steel flanges, special flange clamps are used for connecting two sections of pipelines, and the four corners are connected by bolts after 90-degree flange angles are added.

The air pipe is formed by processing a plate material, wherein two nonadjacent side edges of the plate material need to be subjected to common plate flange forming operation, the other side edge needs to be subjected to seaming forming operation, and the processing operation of the three side edges is extremely difficult to complete on a linear production line because the three side edges of the plate material need to be operated. Therefore, the traditional air duct production line is generally two independent production lines, one production line is specially used for cutting and seaming forming operation of the plate materials, and the seaming forming operation generally uses manually operated semi-automatic equipment; the other production line is specially used for performing flange forming and flanging operation on the plate materials which are subjected to seaming operation, the two production lines are relatively independent, the plate materials need to be manually carried, and the production efficiency is extremely low.

A full-automatic galvanized iron plate and air pipe combination machine is a machine for processing ventilation pipelines made of galvanized iron plates, stainless steel plates and color steel plates in buildings. The thickness of the plate is used within the range of 0.5mm-1.2 mm. The combination machine of the fully automatic galvanized iron sheet air duct machine on the market at present usually comprises components with different machine numbers. Common wind pipe production two-line, three-line and five-line combination machines. The production line of the five-wire combination machine can meet all the procedures of air pipe production generally, and comprehensive automation is realized. The combination machine is a combination device which is operated by a plurality of machines simultaneously, can carry out a plurality of procedures for processing the ventilating duct simultaneously, and mainly completes the manufacture of the air duct formed by the common-plate flange, the angle steel flange or the C-shaped flange.

The common five-wire combination machine is mainly of a linear type structure and a U-shaped structure, wherein the U-shaped structure can save space and is suitable for processing of small and medium-sized plants. However, the width of the whole production line reaches 5000mm, the length reaches over 16000mm, and the occupied area is quite large, for example, a five-line combination machine for air duct production produced by Mei Tech technology Limited company in Ma shan city, Anhui. Although the U-shaped air duct production line is claimed to save space (14m in length), the floor area of the U-shaped air duct production line also reaches 70m2(14X5m), the length of the linear type reaches 22m, and the width of the linear type is about 2m, which means that the area of a production plant needs a large space, the existing air duct production cannot be placed on a construction site or under the condition that the plant is small, and the existing air duct production line is complex in operation, inaccurate in size control and low in production efficiency and quality.

The large size of the combination machine is mainly due to the large size of the components. For example, in a five-line straight-line combination machine manufactured by meit technologies ltd, ma, hui, the manipulator grabs the material and positions the conveying platform, the length of the platform is 3.85m, and the width of the platform is about 1.75-2.00 m. The similar part of the U-shaped machine comprises two transfer platforms, 4.15m in length and 1.55-1.65m in width. The galvanized steel sheet can be conveyed to a proper position for pressing and next step action only through two times of rotation actions of a conveying belt or other similar actions before a single flat mouth of the galvanized steel sheet is machined by the machine, and the mode causes the positioning of the machine to be inaccurate and is easy to generate errors when the steel sheet is moved.

Therefore, the existing air duct production is more complicated and complicated in structure and process, cannot complete the production task under smaller volume, is not suitable for production and processing of small factories, and has higher requirements on production space. The single-flat mouth and the joint angle seaming can not be formed quickly at one time, and the devices can not be accurately connected in real time, so that the production error is easy to generate, and therefore, the production efficiency is low, the production quality is poor, and the cost is higher.
