Double glazing aluminium spacer bar bending apparatus
Technical field
The utility model relates to small-sized machinery processing apparatus, specifically a kind of double glazing aluminium spacer bar bending apparatus.
Background technology
Need carry out bending machining to it during the empty aborning glass of double glazing aluminium spacer bar; Double glazing aluminium spacer bar is a kind of elongated grooved profile; Prior art bender mostly adopt the roll forming of concave, convex roller; When the roll extrusion bending forming, the concave, convex roller that section bar is usually deviate to be shaped influences working (machining) efficiency and crudy.
Summary of the invention
The purpose of the utility model is to the problems referred to above, and its structure is improved, and proposes a kind of double glazing aluminium spacer bar bending apparatus of having good positioning.
The purpose of the utility model is achieved in that a kind of double glazing aluminium spacer bar bending apparatus of the utility model; It comprises frame, bottom roller and upper roller, and above-mentioned bottom roller is installed on the frame, on the frame by the transmission mechanism of forming by handle, screw mandrel and drive block; Upper roller is installed on the drive block; The operator handle is arranged on the upper roller, it is characterized in that the middle indent of lower sheave wheel rim, there is catch its both sides; Top sheave wheel rim intermediate projections, there is catch its both sides.
The double glazing aluminium spacer bar bending apparatus of the utility model is owing to indent in the middle of the lower sheave wheel rim, and there is catch its both sides; Top sheave wheel rim intermediate projections, there is catch its both sides; Top sheave and lower sheave can form the space of sealing when rolling forming.Double glazing aluminium spacer bar is set in the space of above-mentioned sealing, the concave, convex roller that can not deviate to be shaped.The utlity model has working (machining) efficiency height, characteristics that crudy is good.
