Further, the outer side surface of the roller body is provided with at least one annular groove communicated end to end.

Further, connecting portions are arranged at two ends of the roll shaft.

Further, the clamping strips are annularly distributed on the side face of the roller body, and the width of the top of each clamping strip is not smaller than the width of one end of the roller shaft connected with the bottom.

Further, an inner hole position for inserting a screw for locking is formed in the middle of the side face of the clamping strip.

Further, the side face of the roller body is provided with an outer hole site which is positioned between adjacent clamping strips and is locked by inserting a screw.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the limiting and fixed clamping strip connection is adopted between the roll shaft and the roll body, the clamping strip embedded into the roll body can well balance the force during internal rotation, the gasket is used for reinforcing and fixing, the connection part is protected from abrasion, the annular panels which are simultaneously locked with the clamping strip are added on the two sides of the roll body, the stability of the connection between the roll body and the roll shaft is improved, the integral structure is simple, the operation is convenient, and the practicability is strong.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-2, the present utility model provides a roller with stable structure, which is mainly used as a tool for deforming metal connection, and generally needs to be used together with a rolling mill, specifically, the roller comprises a roller body 1 and a roller shaft 2, wherein the roller shaft 2 is controlled by the rolling mill to synchronously drive the roller body 1 to roll for metal deformation processing, therefore, both ends of the roller shaft 2 are provided with connecting parts 8 which are connected with the rolling mill and realize control, and annular grooves 7 on the surface of the roller body 1 realize metal concave-convex processing along with the rotation of the roller body 1, and the annular grooves 7 can be used according to different processing modes without processing modes.

The roller 2 runs through inside the roll body 1 along the center pin direction, the roller 2 side is connected with two at least card strips 3 fixed inside the roll body 1 along center pin direction embedding, card strip 3 still is equipped with gasket 4 with roll body 1 junction, the roller 2 forms detachable structural connection with roll body 1, the roller 2 directly alternates to roll body 1 centre bore department, inside is fixed with card strip 3 and the inboard structure spacing that forms unsmooth of roll body 1, card strip 3 is fixed with the same direction of center pin with rectangular structure, and adopt the mode distribution in roll body 1 side, in order to improve the atress condition of inside card strip 3 when roll body 1 rotates, card strip 3 top width is not less than the width of roll 2 one end is connected to the bottom, avoided the atress not to skid well, still added gasket 4 between the two, this gasket 4 can adopt a soft rubber gasket, for example: the silica gel gasket, except strengthening the stability after the internal connection, can also protect card strip 3 and roll body 1 internal connection department's position not worn and torn.

The roll body 1 is characterized in that annular panels 5 with central holes overlapped with the roll shaft 2 are further arranged on two sides of the roll body 1, the annular panels 5 are embedded into the roll body 1 to be fixed and tightly cling to the clamping strips 3 on the inner sides, the annular panels 5 are assembled with a plurality of screws 6 which are simultaneously locked with the roll body 1 and the clamping strips 3, besides being fixed on the inner sides, the annular panels 5 which are connected together and locked through the screws 6 are additionally arranged at the joint of the roll body 1 and the roll shaft 2, the central part of the roll body 1 is provided with grooves embedded into the annular panels 5, the side surfaces of the annular panels 5 are kept flat after being assembled with the screw body 1, and when the annular panels 5 are locked with the clamping strips 3 and the roll body 1 on the inner sides through the screws 6, the clamping strips 3 are provided with inner hole positions 9 for inserting locking nails 6, and the outer hole positions 10 for inserting the locking nails 6 are distributed in a staggered mode.
