The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

Please in conjunction with Fig. 1, shown in Figure 2, hot-rolled steel crimping of the present utility model portion burr is repaiied shovel device 10 and is comprised handle 11, connecting rod 12 shovels parts 13 with repairing, handle 11 1 ends are provided with socket, inside is cavity structure, and the side at handle 11 socket ends is provided with " L " type bayonet socket 111, the other end in handle 11 inside is provided with extensible member, this extensible member comprises and holds out against screw 141, coil tension spring 142 and baffle plate 143, holding out against screw 141 is located at handle 11 1 ends and inserts that handle 11 is inner to be connected and fixed with handle 11, coil tension spring 142 sheathed with hold out against on the screw 141, baffle plate 143 is connected at coil tension spring 142 other ends; Be the bending of " S " type in the middle of the connecting rod 12, and an end inserts handle 11 inside from socket, and offset with baffle plate 143, also be provided with a card post 121 on the connecting rod 12, when connecting rod 12 inserts, by compression to baffle plate 143, make card post 121 enter in " L " type bayonet socket 111, rotary handle 11 can make card post 121 block mutually with bayonet socket 111 and be fixing; Repair the other end that shovel parts 13 are connected at connecting rod 12.This repair the shovel parts 13 can adopt following four kinds of forms at different veining defects: see also shown in Figure 2, first kind of perching knife 13a that is yi word pattern for the head edge of a knife.This perching knife 13a mainly is applicable to and removes the limit portion wire drawing defective that coil of strip exists, and only needs during use the in-line edge of a knife is enwinded the wire drawing of limit portion, and pulls out wire drawing by rotation and get final product.See also shown in Figure 3, second kind of perching knife 13b that is circular arc type for the head edge of a knife.Can effectively remove the little burr that the top edge of steel flanging part or lower edge exist by the circular arc type edge of a knife of this perching knife 13b, and thinner thickness and have the coil of strip burr of the limit portion changing of the relative positions.See also shown in Figure 4ly, the third is the perching knife 13c of " V " font for the head edge of a knife.Can effectively remove veining defect in coil of strip staggered floor in various degree by " V " font edge of a knife of this perching knife 13c.Please in conjunction with Fig. 5, shown in Figure 6, the 4th kind is the grafter cutter 13d of trapezium structure, this grafter cutter 13d two ends are two edges of a knife that vary in size, and grafter cutter 13d two ends upside is respectively equipped with draw-in groove 131, and corresponding connecting rod 12 1 ends are provided with deck 122, deck spring 123 and bolt 124, deck 122 tightens mutually with the draw-in groove 131 of the corresponding end of grafter cutter 13d by the elastic force that is placed in the deck spring 123 on the connecting rod and fixes, and bolt 124 is located at deck 122 front ends and is passed grafter cutter 13d from top to down.This grafter cutter 13d mainly is applicable to the more smooth existing little veining defect of coil of strip end face, if burr is counted more, area is bigger, can adopt the big edge of a knife of this grafter cutter 13d to remove, if burr is counted less, area is less, but post-tensioning deck 122 makes deck 122 draw-in groove that comes off, then grafter cutter 13d is carried out 180 degree rotations, make the little edge of a knife outwardly, make deck 122 under the effect of deck spring 123, tighten mutually unclamping deck 122 then, thereby adopt the little edge of a knife to remove with draw-in groove 131.

Adopting this to repair shovel device 10 can remove quickly and easily to the different burr of steel flanging part, not only guaranteed the presentation quality of coil of strip, but also can avoid down operation to produce other defective, and hand-holdable handle 11 when using in addition, thus can prevent that hand is scratched.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
