Abstract
The utility model discloses a lining core. The lining core comprises a lining core body which is formed in a cold heading mode. The lining core body is a rotation body piece, a through hole is formed in the middle of the lining core body in a penetrating mode, and the through hole and the lining core body are concentrically arranged. A groove is formed in the position, close to the left end, of the outer circle of the lining core body, a hexagonal force application part is arranged on the right side of the groove, and the radius of the circumference where the force application part is placed is larger than the radius of the circumference of the lining core body. A first groove is formed in the right side of the force application part, and the first groove is attached to the force application part. An external thread part is arranged on the right side of the force application part, a corrugation part is arranged on the right side of the external thread part, and a circular arc is arranged on the right side of the corrugation part. According to the lining core, machining steps are simple, the number of the machining steps is few, the operation difficulty of workers can be lowered to a large extent, meanwhile, the raw material selected by the device is circular bar stock, the cold heading forming mode is adopted, so that the utilization rate of the material is high, the production cost of enterprises is greatly lowered, and therefore the lining core is suitable for popularization.
Description
Technical field
The utility model relates to a kind of lining core.
Background technique
Existing lining core, adopts hexagonal bar cutting to form mostly, and the technique of its processing is comparatively complicated, and the utilization ratio of blank material is lower simultaneously, has therefore caused the waste of material of going up largely, has increased the cost of production of factory.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of lining core, and the processing technology of this device is comparatively simple, and stock utilization is higher, reduces the cost of production of enterprise.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of lining core, comprise the lining core body of cold-heading molding, described lining core body is solid of rotation part, in the middle part of described lining core body, run through and be provided with a through hole, this through hole and concentric setting of lining core body, described lining core body outer ring is provided with groove near left position place, the right side of groove is provided with the force section of a hexagon shape, the residing radius of a circle in this force section is greater than the radius of a circle of lining core body, right side, described force section is provided with the first groove, the first groove and force section are affixed, the right side of described force section is provided with external thread part, the right side of described external thread part is provided with corrugated part, the right side of described corrugated part is circular arc.
As preferred technological scheme, the two ends of described through hole have chamfering.
As preferred technological scheme, described external thread part is trapezoidal thread.
As preferred technological scheme, the degree of depth of described the first groove is greater than depth of groove.
The beneficial effects of the utility model are: the process step of this device is comparatively simple, process step is less, can reduce largely workman's operation easier, the selected raw material of this device are circular bar simultaneously, adopt cold-heading molding, therefore the utilization ratio of its material is higher, greatly reduces the cost of production of enterprise, is therefore applicable to promoting.
