In the tape spool attaching parts of above-mentioned winch, described reaction plate is connected in the connecting portion middle part.The connecting portion middle part is big with the area of contact of reaction plate, connects more firm.
In the tape spool attaching parts of above-mentioned winch, seamlessly transit between the connecting portion of described location lobe and the lobe portion.Connecting portion and lobe portion seamlessly transit, and can not scratch or cut off bundling belt when body rotates.
The utility model also provides a kind of tape spool attaching parts method for making of above-mentioned winch in addition, and this method may further comprise the steps:
A, plate stamping: adopt common decompressor to stamp out rectangular plate body at sheet metal, stamp out simultaneously three location lobes uniform and that be connected as a single entity with plate body in the above-mentioned punching course in the plate body edge;
B, reel: it is cylindric to adopt common reel technology that above-mentioned plate body is rolled into, and obtains the body blank;
C, location lobe moulding: each location lobe is applied external force make the location lobe be 90 degree to be bent to and to connect in the blank, and be formed for first knock hole of fixed core between the adjacent two location lobes.
This method adopts punching press, reel, bending three step modes to make, and makes that the tape spool attaching parts of winch can be one-body molded, sound construction, and processing technology is simple, and is easily manufactured.
In the tape spool attaching parts method for making of above-mentioned winch, to location lobe preforming, each location lobe is applied external force make that angle is 40-50 degree between itself and the reel ends between described step b and the step c.
Disposable bending 90 degree are had relatively high expectations to the extension performance of material, and preforming can prevent that crackle or fracture from appearring in material in the bending process; And preforming can effectively prevent the resilience of material.
In the tape spool attaching parts method for making of above-mentioned winch, adopt common decompressor to stamp out circular reaction plate at sheet metal behind the described step c, stamp out secondary knock hole at reaction plate simultaneously in the above-mentioned punching course.
Secondary knock hole is with the centre hole punching press of centre, one-shot forming, and the working accuracy height, the position deviation of secondary knock hole and centre hole is little.
In the tape spool attaching parts method for making of above-mentioned winch, reaction plate is enclosed within the body outside and make secondary knock hole in first knock hole over against, by common welding process reaction plate is welded on the body then.
Reaction plate is enclosed within on the body, after the rotational fixation dish makes secondary knock hole and first position of positioning hole overlapping, just can welds and be connected.
Compared with prior art, the tape spool attaching parts of this winch only, reaction plate fixing as the master with body is fixed as strengthening, and is simple in structure, easily manufactured; Body and reaction plate act on the body of rod simultaneously, accurate fixed core, and body, reaction plate, the body of rod rotate synchronously, and integral structure is more firm.
