Abstract
The utility model discloses a lining plate nitrogen treatment anti-deformation tooling. Through holes are symmetrically arranged on two lining plates, both ends of a screw bolt pass through the through holes, an inner position limiter is sheathed on the screw bolt and is positioned between the two lining plates, the screw bolt passes through the end parts of the lining plates to be connected with a screw nut, and the screw bolt passes through the end parts of the lining plates to be also connected with an outer position limiter. The lining plate nitrogen treatment anti-deformation tooling can prevent the deformation during the lining plate nitrogen heat treatment.
Description
Technical field
The utility model relates to a kind of nitriding treatment technical field, is specifically related to a kind of liner plate nitriding treatment anti-deformation tool.
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
At above-mentioned technical problem, the purpose of this utility model provides a kind of liner plate nitriding treatment anti-deformation tool, the distortion when the utility model can prevent liner plate nitrogenize thermal treatment.
The technical scheme that realizes above-mentioned purpose is as follows:
Liner plate nitriding treatment anti-deformation tool, on two blocks of liner plates, be symmetrically arranged with through hole, described through hole is passed at the two ends of bolt, be with the inner side limiting-position device on the bolt, this inner side limiting-position device is between two blocks of liner plates, the end that described bolt passes liner plate is connected with nut, and the end that this bolt passes liner plate also is connected with outside stop means.
Described inner side limiting-position device is a sleeve.
Described outside stop means comprises and bolted arm-tie, and the outer screw that is connected with arm-tie, and outer screw is connected its end, back and contacts with liner plate with arm-tie.
Described arm-tie is connected with bolt thread.
Described arm-tie is provided with open holes, and the axial end of described bolt is provided with threaded hole, and arm-tie is connected by screw with bolt.
Adopted such scheme, described through hole is passed at the two ends of bolt, is with the inner side limiting-position device on the bolt, and this inner side limiting-position device is between two blocks of liner plates, the end that described bolt passes liner plate is connected with nut, and the end that this bolt passes liner plate also is connected with outside stop means.Because inner side limiting-position device and outside stop means and liner plate are and are rigidly connected, the direction of the reactive force of Chan Shenging is opposite between the two, if the inner side limiting-position device moves or deformation takes place then the restriction of stop means outside can being subjected to, equally, outside stop means moves or the restriction that deformation also can be subjected to the inner side limiting-position device takes place.Therefore, between two blocks of liner plates liner plate has been formed position-limiting action by the inner side limiting-position device, liner plate is heated in heat treatment process when to the inside deformation taking place, and the effect of inner side limiting-position device can stop liner plate deformation to the inside.And by outside stop means pulling force effect laterally, liner plate is heated in heat treatment process when laterally deformation taking place, the effect of outside stop means can stop liner plate deformation to the inside.
Description of drawings
Fig. 1 is the structural representation of the utility model first embodiment;
Fig. 2 is the structural representation of the utility model second embodiment;
In the accompanying drawing, 1 is liner plate, and 2 is bolt, and 3 is the inner side limiting-position device, and 4 is arm-tie, and 5 is outer screw.6 is nut.
Embodiment
Embodiment one:, be liner plate nitriding treatment anti-deformation tool of the present utility model with reference to Fig. 1.Be symmetrically arranged with through hole on two blocks of liner plates 1, described through hole is passed at the two ends of bolt 2, is with inner side limiting-position device 3 on the bolt 2, and this inner side limiting-position device 3 is a sleeve.This inner side limiting-position device 3 is between two blocks of liner plates 1, and the end that described bolt 2 passes liner plate 1 is connected with nut 6, and the end that this bolt 2 passes liner plate 1 also is connected with outside stop means.Outside stop means comprises and bolted arm-tie 4, and the outer screw 5 that is connected with arm-tie, and outer screw 5 is connected its end, back and contacts with liner plate with arm-tie 4, and arm-tie 4 is threaded with bolt 2.
Embodiment two: with reference to Fig. 2, the utility model is not limited to above-mentioned practical way, and another mode of connection of outside stop means and bolt is: on arm-tie 4 open holes is set, the axial end of bolt 2 is provided with threaded hole, and arm-tie is connected by screw with bolt.All the other are identical with embodiment one, are not explaining at this.
