(1)Pruning shear is ideal for cutting stems,light branche,grass,flower thron and ect.
(2)Fully hardened, precision-ground steel blade stays shrill, even through heavy use. Handles have a nice pattern which makes the pruners easy to hold onto and there's a nice sound of the blades very precisely sliding past each other.
The hook is easy to use and very accessable, making one hand operations a breeze. The best thing about these is that they'll fit in your back pocket and stay locked.
(3)Low-friction coating helps blade glide through wood, prevents the blades from gumming up with sap and debris and helps the blades resist rust.
(4)Maximum cutting capacity: 3 inch diamater

I. Equipment for hollow shaft and rolling bearing The industrial fine grinding mill uses rolling bearings; it has been widely implemented in China; it saves power consumption, advances production value, saves smooth oil, reduces repairs, reduces pollution, etc. Received an outstanding role. At present, some manufacturers imitate the use of rolling bearings in the mill; there are many unreasonable points in the equipment mode of the hollow shaft and the rolling bearing; the manufacturer of the mill is brought to work in the future work. A certain disadvantage. In order to deal with this problem; we put forward the best equipment method for grinding hollow shaft equipment rolling bearings. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The old method of grinding hollow shaft equipment rolling bearing is to process the hollow shaft into the inner diameter of the suitable bearing; the bearing thermal equipment, the bearing part, the outer part of the bearing inner ring has a top sleeve; the top sleeve is pressed into the discharge spiral cylinder (or the feeding and discharging material) The bushing is fixed on the hollow shaft by bolts; the compacting is carried out. During the grinding work; the feeding screw and the fixing bolt are often loose; the top sleeve and the hollow shaft are displaced; the dust will be from the hollow shaft and the top sleeve. The gap between the two enters the bearing box; the smooth grease becomes dirty; the smoothness is caused; the damage of the bearing constitutes an attack.
In order to overcome some of the above defects; let us pass a few years of theory and exploration; portray a new type of equipment approach; and in some applications manufacturers have been outstanding applications.
The method is: the diameter of the hollow shaft device of the mill is thickened; the thin oil cooled by the hollow shaft transfers the temperature of the hollow shaft to the bearing to a normal range below 60 degrees.
The advantages of this type of housing are as follows:
1. Thin oil is smoother than grease smooth; the friction coefficient of the bearing is minimized; the power saving effect is better.
2. The normal working temperature of the bearing; the temperature of the bearing is smoother than that of the dry oil; the service life of the bearing is extended.
3. The lower seat of the bearing is equipped with oil level investigation oil mark; the operator can see the oil level bump at any time; it can make up the oil quantity in time; avoid the smoothness due to lack of oil; avoid the occurrence of bearing damage.
4. The oil chamber of the bearing housing contains oil; the outer diameter of the equipment can be rolled down. ㄔ诒Vã沧敖隽 糜 糜 糜 糜 糜 æ„Ž æ„Ž æ„Ž 疤嵯 疤嵯 疤嵯 疤嵯 疤嵯 æ¢ æ¢ æ¢ æ¢ æ¢ æ¢ æ¢ æ¢ æ¢ æ¢ æ¢ æ¢å—£å«”æž° 嗣嫔枰 嗣嫔枰 虢隽 èª . . . . 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在 在.
The second advantage is that the outer sleeve of the bearing is removed; the dust is prevented from entering the bearing housing; the excellent oil quality is adhered to; the service life of the bearing is ensured; and the work is safe and reliable.
The third advantage is that the diameter of the rolling bearing is increased; the diameter difference is formed with the uniform outer diameter of the hollow shaft; the thin room is selected for the thin oil; the oil level is increased; the thin oil spill has a certain effect.
The fourth advantage is that the diameter of the hollow shaft of the rolling bearing part is thickened; the radial spacing between the rolling bearing and the inlet and outlet spiral cylinder is increased; it plays a certain role of heat insulation and cooling. Cooling and extension of the bearing Use life; play a certain role.
2. Rolling bearing housing and bearing smoothing method Medium-diameter rolling bearing ball mill has been widely used in cement occupation, mine occupation and electric power occupation. The bearing housing of rolling bearing is drawn and produced; most of them use dry oil smooth. From recent years The use of the situation; because the field operators and oilers can not investigate the oil level in time; can not make up for smooth grease in time; the load of smooth grease in the bearing box can not be clearly reflected in time; and the bearing is lack of oil; The attack is light; the lighter constitutes the bearing life shortening; the heavy component constitutes the bearing damage; the new bearing needs to be purchased from the beginning and the equipment; the bearing application manufacturer brings a lot of inconvenience and certain economic loss. In order to deal with this problem; we have studied A new skill in the selection of thin oil-smooth rolling housings.
The lower seat of the bearing seat is composed of two oil chambers and one circulating water chamber; the oil level of each oil chamber can be oriented in the inner diameter of the bearing; the bottom plane of the oil chamber can be to the bottom plate of the oil chamber. One third of the volume is immersed in the thin oil chamber; then the outstanding smoothness of the tumbling bearing is ensured. The center of the two oil chambers is provided with a cooling circulating water jacket; the cooling water cools the oil temperature to the proper temperature of the bearing. Setting; can ensure the smooth bearing needs; do not need to use messy equipment such as peripheral smooth station; also do not need equipment temperature control equipment; can reach safe work.
In summary; this new hollow shaft and roll bearing equipment method and method; is based on the original equipment approach forward and forward. This new thin oil smooth bearing seat; to ensure the outstanding smooth bearing Important. In 2002, our company transformed the main bearing of Φ3×11 m mill of Liaoyang Xiezi Rebirth Cement Factory into a rolling bearing; selected these two practical skills. In 2003, it newly produced Φ3×12 for the cement plant No. 2 in Pinggu District, Beijing. The rice mill also chose this skill; it has achieved outstanding results. At the end of 2005; we carried out the inspection and inspection of the main bearing of Liaoyang Xiezi Rebirth Cement Plant at the end of the year; the wear of the bearing rolling body and the inner jacket ring At around 10μm; it is estimated that the bearing has no problem for more than six years.
It is expected that the new mining bearing mill and the user who will transform the main bearing of the mill into a rolling bearing without theoretical experience; knowing the above-mentioned important new skills; when selecting the manufacturer; should adopt the hollow shaft and rolling bearing equipment of the mill Convex equipment method and thin oil smooth bearing housing; this is a necessary condition to ensure outstanding work of the grinding machine.
