Abstract
The utility model discloses an anti-distortion fixture for liner nitrogen heat treatment on a slitter edge briquetting machine. The anti-distortion fixture comprises a plurality of sleeve gaskets, a plurality of bolts and a plurality of nuts, wherein, the heights of the sleeve gaskets are equal, and the sleeve gaskets are positioned between two liners; the bolts penetrate into through holes formed on the two liners and the sleeve gaskets, and the bolts are screwed in the nuts tightly; and all the sleeve gaskets, the bolts and the nuts are arranged between the two liners. The deformation that is caused when the liners are processed through nitrogen heat treatment is effectively avoided by utilizing the fixture; and the anti-distortion fixture with simple structure improves the clamping efficiency when the liners are processed through nitrogen heat treatment.
Description
Technical field
The utility model relates to a kind of slitter edge briquetting press liner plate nitrogenize heat treatment deformation anchor clamps.
Background technology
Slitter edge briquetting press liner plate needs via nitride thermal treatment, and the nitrogenize thermal treatment of liner plate is liner plate to be put into heat treatment furnace carry out behind clamping usually, but liner plate will deform in heat treatment process; Prevent that at present the measure of liner plate heat treatment deformation from mainly containing the axial free state placement of liner plate, hanging vertical placement of steel wire and backing plate frock locking placement etc.But free state is placed can't effectively overcome the distortion that liner plate produces owing to stress relief when nitrogenize; The laying method that hangs steel wire makes workpiece produce longitudinally easily and stretches, or irregular torsional deformation; Then can can't estimate distortion-free effect with backing plate locking liner plate owing to liner plate and backing plate produce different distortion when the nitrogenize separately.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of slitter edge briquetting press liner plate nitrogenize heat treatment deformation anchor clamps, distortion when utilizing these anchor clamps effectively to prevent liner plate nitrogenize thermal treatment, and this clamp structure is simple, the clamping efficient when having improved liner plate nitrogenize thermal treatment.
For solving the problems of the technologies described above, the utility model slitter edge briquetting press liner plate nitrogenize heat treatment deformation anchor clamps comprise some spacers, some bolts, some nuts, described some spacers are contour and between two blocks of liner plates, described bolt penetrates the through hole and the described spacer of two blocks of liner plates and adopts described nut to be screwed into described bolt tight, and described spacer, screw bolt and nut are distributed between two blocks of liner plates.
Unlikely impaired during for protection liner plate clamping, these anchor clamps also comprise some packing rings, and described packing ring penetrates described bolt and lays respectively at the outer side of two blocks of liner plates.
Because it is to state technical scheme that the utility model slitter edge briquetting press liner plate nitrogenize heat treatment deformation anchor clamps have adopted, and some spacer rings promptly are set between two blocks of liner plates, liner plate and some spacer rings are tight by the screw bolt and nut handle; Some spacer rings are processed as contour, have guaranteed the spacing of two blocks of liner plates, do not influence the nitrogenize thermal treatment of two blocks of liner plates thus; Distortion when utilizing these anchor clamps effectively to prevent liner plate nitrogenize thermal treatment, and this clamp structure is simple, the clamping efficient when having improved liner plate nitrogenize thermal treatment.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the utility model slitter edge briquetting press liner plate nitrogenize heat treatment deformation anchor clamps clamping synoptic diagram.
Embodiment
As shown in Figure 1, the utility model slitter edge briquetting press liner plate nitrogenize heat treatment deformation anchor clamps comprise some spacers 1, some bolts 2, some nuts 3, described some spacers 1 are contour and between two blocks of liner plates 5, described bolt 2 penetrates the through hole and the described spacer 1 of two blocks of liner plates 5 and adopts described nut 3 to be screwed into described bolt 2 tight, and described spacer 1, bolt 2 and nut 3 are distributed between two blocks of liner plates 5.
Unlikely impaired during for protection liner plate 5 clampings, these anchor clamps also comprise some packing rings 4, and described packing ring 4 penetrates described bolt 2 and lays respectively at the outer side of two blocks of liner plates 5.
The utility model slitter edge briquetting press liner plate nitrogenize heat treatment deformation anchor clamps are provided with some spacer rings 15 of two blocks of liner plates, and liner plate 5 and some spacer rings 1 are tight by bolt 2 and 3 on nut; Some spacer rings 1 are processed as contour, have guaranteed the spacing of two blocks of liner plates 5, do not influence the nitrogenize thermal treatment of two blocks of liner plates 5 thus; Be vertically placed on the table 6 during two liner plate 5 shove charges, whether the deformation tendency when no matter two blocks of liner plates 5 discharge stress during nitrogenize is consistent, the bigger liner plate of deformation tendency all can be because of another piece liner plate to the obstruction of its distortion and make moderate progress, no matter the deformation tendency of two blocks of liner plates 5 is that in opposite directions or dorsad the existence of spacer 1 can make this trend offset.If deformation tendency is consistent,, a bigger liner plate of distortion improves the distortion situation thereby can being subjected to the power opposite with deformation direction owing to the trend of another piece liner plate is less.Distortion when utilizing these anchor clamps effectively to prevent liner plate nitrogenize thermal treatment, and this clamp structure is simple, the clamping efficient when having improved liner plate nitrogenize thermal treatment.
Claims (2)
