Description

一种挤出机的双金属机筒
技术领域
[0001] 本实用新型涉及挤出机机筒,具体涉及一种挤出机的双金属机筒。
背景技术
[0002] 挤出机的机筒是挤出机的重要部件,挤出机的机筒和螺杆配合实现对塑料的粉碎、软化、熔融、塑化、排气和压实,因此挤出机机筒必须要具备耐高温、耐压强、耐腐蚀的特性,现有技术中的挤出机机筒多数以氮化钢为原料的一体结构,这种结构耐高温、耐腐蚀性能有限,并且随着磨损深度的增加,氮化钢的硬度急剧下降,需要经常更换,大大增加企业的生产成本。
发明内容
[0003] 为解决现有技术存在的问题,本实用新型提供了一种具有超强耐高温、耐腐蚀性能和超长使用寿命的挤出机的双金属机筒。
[0004] 本实用新型通过以下技术方案实现的:包括筒体,筒体内还设有内壁为8字形、夕卜壁为椭圆形的连体衬套,所述连体衬套外表面与筒体过渡配合连接。所述连体衬套内壁设有一层厚度为2_的合金材料。
[0005] 所述连体衬套以镍基合金为基体,经过先进的生产工艺将含有大量的钨、碳等合金高速均匀喷涂到基体表面成型,所说连体衬套采用离心浇铸在机筒内壁。
[0006] 本实用新型的有益效果是:采用连体衬套与筒体配合的方式,连体衬套使用镍基合金制成,筒体采用普通钢材制成,相对于传统的一体式机筒来说,减少了 90%的材料成本。并且本实用新型具有超强的耐磨损、耐高温、耐腐蚀性能,大大延长了挤出机机筒的使用寿命。
附图说明
[0007] 图1是本实用新型的截面示意图。
具体实施方式
[0008] 如图1所示,本实用新型包括筒体1,筒体I内还设有内壁为8字形、外壁为椭圆形的连体衬套3,所述连体衬套3外表面与筒体I过渡配合连接。所述连体衬套3内壁设有一层厚度为2mm的耐磨耐腐蚀的合金材料。
[0009] 最后应当说明的是,以上内容仅用以说明本实用新型的技术方案,而非对本实用新型保护范围的限制,本领域的普通技术人员对本实用新型的技术方案进行的简单修改或者等同替换,均不脱离本实用新型技术方案的实质和范围。

Claims (2)

1.一种挤出机的双金属机筒,包括筒体(1),其特征在于:筒体(I)内还设有内壁为8字形、外壁为椭圆形的连体衬套(3),所述连体衬套(3)外表面与筒体(I)过渡配合连接。
2.根据权利要求1所述的一种挤出机的双金属机筒,其特征在于,所述连体衬套(3)内壁设有一层厚度为2_的合金材料。
