Sharpening is an indispensable preparation procedure before drawing die. According to the introduction, the rotary forging machine has been used in the coarse wire rolling abroad. It is also useful for electric rolling, that is, the two ends of the wire are clamped with electric pliers, and then the wire is stretched into a point and broken. At present, all the domestic use of rolling rod tip, mainly the reciprocating rotary old rolling machine and eccentric rolling machine cycle rotation. Another lever manual reciprocating small tip rolling machine, specially for 1 mm below the use of fine steel wire.
Fold and edit the structure of this section sharpening machine
The reciprocating rotary tip rolling machine is used for decades of old equipment, simple structure, suitable for small factories and production of low carbon steel wire.
This equipment is composed of three parts: transmission, frame and rolling stick. It is reduced by belt wheel and gear, and the big gear rotates about 60 times per minute. A short eccentric shaft is attached to the side of the big gear, which makes the rolling stick rotate around 50° through the arm and connecting rod. If the position of the arm and the connecting rod is changed, the Angle of the rolling rod can be changed.
This old fashioned bar is 100~120 mm in diameter and has 8~16 slots. According to the diameter of the wire, slot from large to small in order. Slot compression rate is: coarse steel wire about 20%, medium and fine specification about 15%. The slot is concentric and symmetrical with the outer circle.
The working principle of the sharpening machine is shown in the figure below.

The Ministry of Environmental Protection recently notified the administrative punishment decision of Shandong Kama Automobile Manufacturing Co., Ltd. and Shandong Tangjun Ou Ling Automobile Manufacturing Co., Ltd. to violate the air pollution prevention and control system, and required all levels of environmental protection departments to fully implement the newly revised Air Pollution Prevention and Control Law and severely punish Production of excessive motor vehicles and pollution control devices fraudulent behavior. The two cases, as the first case of the Ministry of Environmental Protection after the 19th National Congress, have a demonstration effect and will have a strong deterrent effect on similar environmental violations.
The relevant person in charge of the Ministry of Environmental Protection said that the carbon light + nitrogen oxides and carbon monoxide emitted by eight light-duty diesel trucks produced by Shandong Kama Automobile Manufacturing Co., Ltd. exceeded the emission standards; the OBD system functional test of 318 heavy-duty diesel trucks produced If it is unqualified, the pollution control device will be falsified, shoddy, and sold as a qualified product. In accordance with the first paragraph of Article 119 of the Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution, the Ministry of Environmental Protection ordered the Kama Company to correct the illegal activities of motor vehicles that exceeded the pollutant discharge standards, confiscated the illegal income of 12,786.80 yuan, and delivered the goods. The amount of the amount is twice the amount of 514,559.52 yuan, and the total amount of fines and penalties is 527,346.32 yuan. In accordance with the second paragraph of Article 119 of the Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution, the Ministry of Environmental Protection ordered Kama to suspend production of illegal and fraudulent use of pollution control devices. Remediation, confiscation of 718,194.05 yuan of illegal income, and a fine of 30,496,562.52 yuan twice the value of the goods, a total of 31,214,756.57 yuan. The above various fines and penalties totaled 31,742,102.89 yuan.
The emissions of hydrocarbons + nitrogen oxides and carbon monoxide from 109 light diesel trucks produced by Shandong Tangjun Ou Ling Automobile Manufacturing Co., Ltd. exceeded the discharge standards. In accordance with the first paragraph of Article 119 of the Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution, the Ministry of Environmental Protection ordered Tang Jun Ou Ling Company to correct the illegal activities of motor vehicles that exceeded the pollutant discharge standards, and confiscated the illegal income of 112,502.48 yuan. The fine of the value of the goods is twice the amount of 69,238,815.16 yuan, and the total amount of fines and fines is 703,361.76 yuan.
The relevant person in charge of the Ministry of Environmental Protection pointed out that the Ministry of Environmental Protection directly imposed administrative penalties on the above two typical environmental violation cases, and issued tens of millions of fines for the two motor vehicle manufacturers, indicating that the Ministry of Environmental Protection had “zero†for illegal sewage disposal. Tolerate" attitude. This move laid a solid foundation for the implementation of motor vehicle and oil product supervision and inspection in the country in 2018. It is an important measure to implement the report of the 19th National Congress of the Communist Party of China and resolutely win the battle against blue sky.
