The historical origin of traditional pole scale production technology

After the 50's, Hanzhong scale industry with the various "campaigns" a few ups and downs, suffered a lot, Zhang Zhaojin, Liu Defu master and disciple as the main technical backbone has been in the industry to persist in the work; during the period of many innovations, independently invented a relatively convenient, sensitive 10 kg case scale; in 1972, but also had to go to Xi'an to learn the 250 kg In 1972, he also went to Xi'an to learn the practice of 250kg weighing scale, and successfully developed it in 1977. After Zhang Zhaogin's death in the 1980s, Liu Defu became the oldest (more than 70 years by the beginning of the 21st century) and most versatile traditional artisan in the handmade scales industry in Hanzhong City and Shaanxi Province; his scale store also survived.

The history of the development of modern scale production in Hanzhong is roughly stated as follows:

①After the outbreak of the Anti-Japanese War, the country's economic center of gravity shifted westward, and a large number of refugees fled from their hometowns

②To Hanzhong, Hanzhong's economy has grown substantially, and at this time, merchants gathered, and the demand for the scales necessary for trading has also increased dramatically, and at that time, a pole weighing was sold for as much as 40 yuan of the present foreign currency, which is the first boom of the scale industry in Hanzhong. Hanzhong pole scale industry's first boom.

340s the end of the war of resistance against Japan, the original asylum seekers to return home, a large number of business people to reduce the Hanzhong economy a moment of depression; at the same time, the government to rectify the city, the provisions of the streets are not allowed to stalls, under the double blow to the Hanzhong scale sales fell sharply, which is the first low period of the Hanzhong rod scale.

4 In 1950, China's national economy began to recover, to 1956 to carry out agriculture, handicrafts, cooperative, Hanzhong scale practitioners *** counted 7 households l3 people merged into Hanzhong County Weighing Factory, expanding production. The prosperity of the pole scale market in this period and the collectivization of rural economic Qi is symbiotic, then an agricultural cooperative is divided into several brigades, brigades are divided into several squads, because of the collective distribution, each squad needs three measurements of different weights of scales, Hanzhong pole scales of the business was immediately red-hot, and for a time buy scales of the people lined up in a long queue; Hanzhong County Scale Co-operative Factory to buy land to expand, more than 30 young apprentices recruited for the pole scale training, but also sent out part of the scale factory. Pole scale training, but also sent out some people to learn sand casting, for the production of scales to make preparations, Hanzhong pole scale ushered in the second boom period.

5 In 1958, during the "Great Leap Forward" and the "Great Iron and Steel Refining" period, the "****production wind" of "one flat and two adjustments" was rampant. "rampant, the county government from the Hanzhong scale cooperative factory free expropriation of its collective funds to purchase a new factory, requisitioned away just cultivated more than 20 young casting, the plant was greatly injured, when the best-selling scales can not be normal production.

660s, Zhang Zhaojin, Liu Defu and other old technical backbone efforts to develop production, even in the "Cultural Revolution" turmoil, but still overcome all the difficulties and continue to develop new types of scales in order to increase the factory's economic benefits. 1969 case of the scale was successfully developed in 70 years to Xi'an to accept the provincial inspection to meet the standards to allow production. 1977, and the trial production of 250 kg scale was successfully completed, and in 1977, the factory was also the first to develop a new type of weighing scale; In 1977 and the success of the trial production of 250 kilograms of scales, the market is very good; this period of the factory's product sales and repair services from the province extended to Sichuan, Gansu and other places, is still the momentum of development.

770s after the state-run factories also case culmination of production, Haniu Weighing Factory's case of scales were to be "not standard" banishment. Hanzhong pole scale production faced complex oppression and challenges, in the second decline. But to the early eighties reform and opening up, the whole of China's economic policy relaxation, structural adjustment revitalization, market trade flourished, led to an increase in small traders and vendors. And vendors like to use the easy-to-carry pole scale, the demand for pole scale with the reform and opening up of the tide and hot up, which is the third boom period of Hanzhong pole scale.

8 into the nineties, with the emergence of a large number of electronic scales in the market, coupled with the Hanzhong Weighing Factory (appointed by the government sector) several leaders in the tide of reform and decision-making errors, Hanzhong Weighing Factory was repeatedly hit, and ultimately collapsed. 2007 Hanzhong Weighing Factory bankruptcy to deal with the old factory site was purchased, only to make up for dozens of old workers' social security payments. Some of the old craftsmen in retirement also had continued to do business in pole scales, but due to poor management or technical incomplete and one after another to close, leaving only Zhang Defu family can still support the facade, Hanzhong pole scales production process is facing the most dangerous decline and demise of the destiny.
