Special reducer for cold cutting saw

Shenyang Today Transmission Machinery Co., Ltd. is a type of enterprise that integrates research, design, manufacturing, and sales of intelligent steel bar deep processing equipment. The enterprise has introduced advanced foreign talents and collaborated with universities to develop and produce intelligent CNC steel bar deep processing equipment and steel bar deep processing distribution.

To provide more and more convenience for mining, large-scale engineering machinery production enterprises or enterprise groups will develop rapidly through endogenous growth and external expansion, expand their scale, increase product types, and grow into comprehensive engineering machinery enterprises. At the same time, the concentration of the industry will further increase

The company has established a construction industry machinery and equipment manufacturing base, and has set up intelligent deep processing centers for steel reinforcement products in Jining Economic Development Zone, Lanzhou New Area, Nanning, Nanjing and other places. It has formed an annual processing capacity of 1 million square meters for steel truss floor slabs urgently needed in prefabricated buildings, and is a leading enterprise in the domestic steel reinforcement processing equipment manufacturing and steel reinforcement product processing industry. The company has strong capabilities and a design and development team of more than 30 people. So far, it has obtained over 30 awards. We can customize design and production according to different user needs, assist users in planning production processes, configure equipment reasonably, provide applicable production management support services, solve practical problems, and create value for users. The fully automatic steel cage rolling welding machine launched in the domestic market in 2008 filled the gap in the mechanization of steel cage forming in China, ended the history of manual cage binding, and obtained the national first-class construction method. Currently, this operation method is widely used in key projects in China. The company's multiple products have high content and market value, laying a solid foundation for the company's development. Management is the core competitiveness of a company, and the core of management is talent. The company cultivates numerous management talents who play important roles in different positions. It implements a comprehensive modern enterprise management model and adopts scientific management software such as OA, ERP, CRM, MERP, etc. in enterprise management, promoting the modernization and scientificization of enterprise management and meeting customer needs at a fast pace.

It indicates that the upper and lower chambers of the oil cylinder are connected when the work is in progress, and the pressure difference tends to be zero, so it cannot enter normally. After removing the one-way valve that leaked oil, it was found that an additional 3mm diameter small steel ball was installed. After removing the small steel ball, the oil cylinder was cleaned and reinstalled, and the bow saw was started for cutting. Everything is normal. The sawing machine is a relatively simple machine tool, and users do not require their sawing machine to have the function of a machining center

The working principle of sawing machine:

Before starting the lubrication system, it is necessary to add oil to the lubrication parts of the machine tool (wire brush shaft, worm gear box, active bearing seat, worm bearing, upper and lower shafts of the lifting oil cylinder, and clamping screw of the sliding surface of the movable vise) according to the requirements. The worm gear and worm gear inside the worm gear box are lubricated with No. 30 engine oil bath, injected through the oil plug hole on the upper part of the worm gear box. The box surface is equipped with an oil gauge. When the saw beam is in position, the oil level should be between the upper and lower limits of the oil gauge. The oil should be changed after one month, and then every 3-6 months. There is an oil drain plug at the bottom of the worm gear box.

The hydraulic transmission system is a hydraulic circuit composed of auxiliary components such as pumps, valves, oil cylinders, oil tanks, and pipelines. It completes the lifting and clamping of the saw beam and workpiece under electrical control. The feed speed can be infinitely adjusted through the speed control valve to meet the cutting needs of workpieces of different materials. The electrical control system consists of a control circuit consisting of an electrical box, a control box, a junction box, a travel switch, an electromagnet, etc. It is used to control the rotation of the saw blade, the lifting and lowering of the saw beam, the clamping of the workpiece, etc., to achieve normal cutting cycles according to a certain working program.

The saw blade drive is installed on the worm gear box, and the electric motor drives the worm and worm gear inside the worm gear box through a pulley and a triangular tape, which drives the active wheel to rotate and then drives the saw blade wound on the active and passive wheel rims to perform cutting and rotating motion. The feed motion of the saw blade is controlled by a hydraulic circulation system consisting of a lifting cylinder and a speed regulating valve, which controls the descent speed of the saw beam and thus controls the feed motion of the saw blade (stepless speed regulation). The saw brush rotates at the location where the saw blade produces chips, and rotates in the direction of the saw blade. It is cleaned with coolant supplied by a cooling pump to remove chips from the saw teeth. The coolant is stored in the cutting fluid tank on the right side of the base and is directly driven by a water pump to supply coolant.

Sawing machine

Mature production technology and advanced equipment and processing tools are the key to ensuring product quality. The company has invested tens of millions of yuan to establish a CNC machining center, ensuring the production of high-quality products and the trial production of new products. It has the ability to produce 1000 sets of various CNC steel bar processing equipment annually and is a leading enterprise in the steel bar processing equipment industry.

The import tariffs and import value-added tax paid for raw materials will be collected first and then refunded. The refunded tax will be treated as national investment and converted into national capital, mainly used for the research and development of new products and independent capacity building of enterprises. It is believed that with the joint efforts of policies and enterprises, China's large-scale mining equipment will gradually move towards intelligence There are generally three feeding methods for sawing machines: first, manual feeding: by manually using a manual feeding rack to feed the material to the sawing position, manually or using a sawing machine to measure the size to be sawed, which is suitable for small-sized materials; second, mechanical transmission feeding: through a motor,speed reducerChain wheel drives the feeding roller to rotate
