在预应力混凝土空心板的生产中,各类拉模成型机占主导地位,其构造简单、易损件少,保养费用较低,但在提高制品质量及降低劳动强度诸方面则明显不及挤压成型机;然而,挤压机的主要工作部件——挤压螺旋磨损较大,其使用寿命虽已达1～1.5万延长米,但仍需用户付出6000～10000元/年易损件更换费。提高构件厂的经济效益是需进一步解决的问题。近两年正式投入市场的预应力混凝土空心板推挤成型机,既继承了挤压成型机的优点,又解决了易损件费用高的问题,是一种颇具发展潜力的混凝土预制构件生产设备,博山建筑机械厂已获取推挤成型机生产专
In the production of prestressed concrete hollow slabs, various types of die-casting machines dominate, and their structures are simple, there are few wearing parts, and maintenance costs are low. However, they are obviously less effective in improving product quality and reducing labor intensity. Forming machine; However, the main working part of the extruder - the extrusion screw wear is large, although its service life has reached 1 to 15,000 meters, but still require the user to pay 6000 to 10,000 yuan / year wearing parts replacement fee . To improve the economic efficiency of component plants is a problem that needs to be further addressed. In the past two years, the prestressed concrete hollow slab push molding machine officially put into the market not only inherited the advantages of the extrusion molding machine, but also solved the problem of high cost of wearing parts. It is a production equipment for concrete prefabricated parts with considerable development potential. , Boshan Construction Machinery Factory has obtained the push extrusion molding machine production
