Title
(EN) Heat recovery core body edge strip rolling production line and production method
(ZH) 热回收芯体边条辊压生产线及其生产方法
Abstract
(EN)
The invention provides a heat recovery core body edge strip rolling production line. The heat recovery core body edge strip rolling production line comprises a band steel uncoiling machine, a hole punching and angle cutting machine, a rolling machine and an angle folding cutting machine which are arranged in sequence; circular holes and rectangular gaps are punched and cut in band steel by the hole punching and angle cutting machine; the circular holes serve as mounting holes of an end part of a heat recovery core body edge strip; the rectangular gaps serve as bending space; the band steel which is subjected to hole punching and angle cutting is cold-bent into an L-shaped profile by the rolling machine by adopting a progressive roll along the central axis of the band steel; the L-shaped profile is cut by the angle folding cutting machine from adjacent edges of the rectangular gaps; and meanwhile, the two sides of an incision are bent into a mounting end which is perpendicular to the L-shaped profile. According to the heat recovery core body edge strip rolling production line, the heat recovery core body edge strip is rolled only by cold bending by directly using the band steel; theutilization rate of raw materials is extremely high; the interchangeability and the versatility of components are extremely high; a mould is not required to be replaced for the heat recovery core bodies with different height, and only the stepping parameters of feeding of the angle cutting machine and the angle folding cutting machine are required to be adjusted, so that the concept of lean production is met; and the competitive power of the product is improved.

本发明提供一种热回收芯体边条辊压生产线,包括依次布置的带钢开卷机、冲孔切角机、辊压机和折角切断机;冲孔切角机在带钢上冲切圆孔和矩形缺口,圆孔作为热回收芯体边条端部的安装孔,矩形缺口作为折弯的空间;辊压机采用渐进的轧辊沿带钢中轴线将冲孔切角后的带钢冷弯成L型材;折角切断机从矩形缺口的相邻边上切断L型材切,同时将切口两侧折弯成垂直于L型材的安装端。本发明直接使用带钢仅冷弯压制热回收芯体边条,原材料的利用率极高,零件的互换性与通用性极高,对于不同高度的热回收芯体,无需更换模具,仅需在调整切角机与折角切断机送料的步进参数,符合精益生产的理念,提升了产品的竞争力。
