摘要
The method comprises manufacturing a frame (10) of a C-clamp, which has a lower jaw (20), an upper jaw (30) and a mouth (26) between the lower jaw and upper jaw. The method comprises forming a lower end plate (22) and an upper end plate (32) and at least two frame plates (10a, 10b, 10c, 10d), which have a lower branch (12) and an upper branch (14). The lower branches of the frame plates are attached to the lower end plate and the upper branches to the upper end plate, so that the frame plates settle in a parallel manner at a distance (e) from each other. The joined frame plates and end plates form the frame of the C- clamp. The frame plates are formed by machining a steel plate of ultra-strength steel only with machining methods, which do not substantially heat up the material being machined. Suitable machining methods are for example chipping machining methods or water cutting. The lower branches are attached to the lower end plate and the upper branches are attached to the upper end plate by welding or with mechanical attaching means. The attaching point of the end plates is situated as far away as possible from the most stressed point in the frame plates, so a localized decrease in strength in the ultra-strength steel possibly caused by the welding does not affect the total strength of the frame in a decreasing way. The number of frame plates can be selected according to the strength requirements of the frame. There can thus be for example three, four, five, six, seven or eight frame plates.
