Description
Technical field:
The utility model relates to pelleter technical field, particularly a kind of pressure roller.
Background technology:
Existing pelleter is mainly used in plastics reprocessing, cannot be used for the large material of cutting hardness, such as lead; hardness is large; cutting difficulty, cutting accuracy is low, and existing pelleter mainly utilizes cutting knife to realize pelletizing; cutting knife is made up of rotor and stationary knife two parts; cutter is apart from being controlled by stationary knife position, and cutting efficiency is low, complex structure; therefore, people need to seek a kind ofly can cut hard object and the high cutting part of cutting accuracy solves the problems referred to above.
Utility model content:
The purpose of this utility model is to provide a kind of pressure roller, has cutting function, cuts in the process of compacting simultaneously, and realize compacting cutting one-shot forming, structure is simple, and cutting accuracy is high, time saving and energy saving, increases work efficiency, and reduces production cost.
To achieve these goals, the utility model adopts following technical scheme: a kind of pressure roller, comprise: comprise cylinder and cylindrical shape roll body, cylindrical shape roll body is arranged on cylindrical outer, with outer surface of cylinder integrally casting, cylindrical shape roll body is coaxial with cylinder, roll body outer surface forms pressed surface, and described pressed surface is provided with the overflow area of multiple compacting figure chamber and multiple depression, and compacting figure chamber and overflow area are alternately arranged, roll body surface is steel alloy, and hardness is HRC 58-62.
Above-mentioned steel alloy is 20CrNiMo.
Above-mentioned compacting figure chamber is cone square hole, and pressed surface is provided with 96 cone square holes.
Above-mentioned pressed surface is evenly carved with many strias.
The size in above-mentioned compacting figure chamber is identical with product size, and compacting is provided with circular hole bottom figure chamber, and circular hole is through roll body and cylinder, and circular hole area is less than the floor space in compacting figure chamber.
Relative to prior art, the utility model has the following advantages:
1, roll body surface is 20CrNiMo steel alloy, after carburizing and quenching, hardness is for being promoted to HRC 58-62, and compacting figure cavity edge is enough hard, cut while compacting, realize compacting cutting one-shot forming, solve product from single production to the question of substance of batch production, structure is simple, cutting accuracy is high, time saving and energy saving, improve operating efficiency, reduce production cost.
2, pressed surface is carved with stria, increases frictional force during pressure roller running, ensure that the accuracy of compacted products.
The size of 3, suppressing figure chamber is identical with product size, and compacting is provided with circular hole bottom figure chamber, and circular hole is through roll body and cylinder, and circular hole area is less than the floor space in compacting figure chamber, by circular hole, takes out after facilitating formed product.

Fig. 2 is the schematic diagram in A-A face of the present utility model.
In figure, 1, cylinder; 2, roll body; 3, pressed surface; 4, figure chamber is suppressed; 5, overflow area; 6, circular hole.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in more detail.
As depicted in figs. 1 and 2, a kind of pressure roller, comprise: cylinder 1 and cylindrical shape roll body 2, it is outside that cylindrical shape roll body 2 is arranged on cylinder 1, with cylinder 1 outer surface integrally casting, cylindrical shape roll body 2 is coaxial with cylinder 1, roll body 2 circumferential outer surface forms pressed surface 3, and described pressed surface 3 is provided with the overflow area 5 of multiple compacting figure chambeies 4 and multiple depression, and compacting figure chamber 4 is alternately arranged with overflow area 5, roll body 2 surface is steel alloy, and hardness is HRC 58-62.
Further, described steel alloy is 20CrNiMo.
Further, described compacting figure chamber 4 is cone square hole, and pressed surface 3 is provided with 96 cone square holes.
Further, described pressed surface 3 is evenly carved with many strias.
Further, the size in described compacting figure chamber 4 is identical with product size, and compacting is provided with circular hole 6 bottom figure chamber 3, and circular hole 6 is through roll body 2 and cylinder 1, and circular hole 6 area is less than the floor space in compacting figure chamber.
Above-mentioned pressure roller is main pressure roller, with another secondary pressure roller with the use of, secondary pressure roller is identical with main pressure roller figure, the compacting figure chamber 4 of main pressure roller is corresponding with the overflow area 5 of secondary pressure roller, the overflow area 5 of main pressure roller is corresponding with the compacting figure chamber 4 of secondary pressure roller, because roll body surface is 20CrNiMo steel alloy, after carburizing and quenching, hardness is HRC 58-62, compacting edge, figure chamber 4 is enough hard, cut while compacting lead, realize one-shot forming, solve product from single production to the question of substance of batch production, cutting accuracy is high, time saving and energy saving, improve operating efficiency, reduce production cost.
Pressed surface 3 is carved with stria, increases frictional force during pressure roller running, ensure that the accuracy of compacted products.
The size in compacting figure chamber 4 is identical with product size, and compacting is provided with circular hole 6 bottom figure chamber 4, and circular hole 6 is through roll body 2 and cylinder 1, and circular hole 6 area is less than the floor space in compacting figure chamber, by circular hole 6, takes out after facilitating formed product from compacting figure chamber 4.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the utility model by submitted to claims determination scope of patent protection.
