Shares in small companies in IT, biotech and new material sectors that have been in a tailspin of late, are expected to slump further, while coal, steel and nonferrous metal stocks are tipped to coast on the respective companies' brightening business performance.凌源钢筋镦粗机价格恩施钢筋冷镦机厂家直销凌源钢筋镦粗机价格河北沧州钢筋镦粗机厂家直销凌源钢筋镦粗机价格
钢筋镦粗机采用先进液压系统和电动结构原理;无需在高压力的动态下工作;镦粗操作只需按上一个电源按扭,10多秒钟的时间,整体镦粗工作一次性完成,为了确保安全文明生产,操作简单、方便;在镦粗当中,模具可长期使用、无损耗,而且一套规格的模具可加工2种规格的钢筋,加工精度高,质量保证。大大降低了劳动成本,提高生产效益,几分钟的专业培训即可上岗操作。钢筋镦粗利用冷镦的原理使钢筋端头塑性变形,直径增大4~6mm,然后再加工螺纹。使加工螺纹后的实际截面积大于原钢筋截面积,大大提高接头的抗拉强度。这种镦粗后的螺纹接头经拉伸实验检测全部断于母材,适用于建筑、路桥、电站等要求较高的工程。
用途:
本机是建筑钢筋机械连接(镦粗直螺纹连接)的前道机械,它的主要功能是把建筑钢筋端部挤压镦粗,达到增加钢筋截面积的目的,它适用于Φ16-Φ32mm的II、III级建筑钢筋。
设备特点:
(1)操作简单,液压电气控制,不需要专业技工,培训十分钟即可开机操作;
(2)将钢筋端部截面积扩大15-20%,使加工成螺纹的底径不小于钢筋母材直径,完全发挥抗拉强度。
(3)生产效率高,每台班可镦粗300-500个头;
(4)加工钢筋范围广,可加工符合GB1499或BS4449(CS2)标准的Ф12-Ф50各种规格的钢筋。
(5)设备故障率小,无易损零配件,施工成本底。

镦粗机的特点;
钢筋镦粗机 低流量 低耗能 精度高的钢筋头部价格。其它建材GDCJ-40钢筋镦粗机鐓粗压直螺纹连接技术,是用专用的鐓粗机预先将钢筋端部待加工螺纹段鐓粗,使其加工鐓粗部位直径增粗至大于母材直径。然后用配套专用的套丝机对其鐓粗部分进行套丝加工,再用同规格套筒将加工好的两根钢筋头部套丝螺纹部位用扳手进行连接,即完成所谓钢筋的对接。鐓粗等强直螺纹连接技术具有性能稳定,连接省力快捷,检验合格率高等优点,也同时可以完全解决钢筋不可转动连接的难题。
Then the door opened and two little girls entered, followed by a young lady, who regarded with some anxiety the lively way in which little Rita ran bounding through the room in order finally to spring with one big leap on her papa's knee. By her skill in jumping it was plain to see that it was not the first time she had accomplished this. Rita now looked triumphantly around as if to say: "Now I am once more seated in my strong castle where no harm can reach me!"凌源钢筋镦粗机价格青海西宁钢筋镦粗机南阳宝欣机械凌源钢筋镦粗机价格钦州钢筋镦粗机南阳宝欣机械凌源钢筋镦粗机价格The price-earnings ratio of ChiNext stocks had peaked around 150 in 2015, exerting a great deal of pressure on the index, said Chen Jiahe, chief analyst of Cinda Securities.
