Description
Technical field
The present invention relates to a kind of chain processing method.
Background technique
Chain is generally chain link or the annulation of metal, multiplexly does mechanical transmission, traction.
The inside drive chain of heavy mechanical equipment is to meet larger driving force or tractive force between each part of machine internal, and the generally common chain volume of its volume ratio is large, and overall quality is heavier.Be flexibly connected by pin between the chain unit of existing this kind of chain, when chain carries out transmission operation, mutually rotate between chain unit and rub, pin is easily ruptured, interconnective chain unit is caused to disconnect, repair and waste time and energy, have impact on the normal operation of heavy mechanical equipment, reduce manufacturing efficiency.
Summary of the invention
The object of this invention is to provide a kind of chain processing method, this chain processing method is simple to operate, and the chain structure processed is stable, rotation is flexible, long service life.
To achieve these goals, the invention provides a kind of chain processing method, comprising:
(1) steel plate is cut into polylith inner plate raw sheet and outer plate raw sheet;
(2) on described inner plate raw sheet and outer plate raw sheet, multiple mounting hole is all drilled with to form inner plate and outer plate;
(3) double end rivet is greater than the end of described double end rivet bore with the bore at the middle part making described double end rivet is processed;
(4) two ends of two described inner plates are sheathed on the end of described double end rivet by mounting hole, then two described outer plates are sheathed on the end of described double end rivet, more described double end rivet is processed into riveted joint to form chain unit;
(5) two ends of multiple described chain unit are formed the chain of ring-type by described double end rivet successively movable riveted joint.
Preferably, in step (1), described outer plate raw sheet is polygonal panel.
Preferably, described step (2) also comprises: the wedge angle of described outer plate raw sheet is machined to rounded corners.
Preferably, described double end rivet is spindle structure.
Preferably, be solid of rotation in the middle part of described double end rivet, the end of described double end rivet is cylindrical body, and the bus of described solid of rotation is the curve of indent and the end radius of described solid of rotation is greater than described cylindrical end radius.
According to technique scheme, connection between the chain unit of chain is changed over rivet activity riveted joint by pin connection by the present invention, and bore rivet being processed into middle part is greater than the bore of end, decrease when chain rotates, mutual rotation between chain unit is to the radial force suffered by the wearing and tearing of joint and movable rivet of riveting, extending the working life of chain, avoiding frequently changing chain to producing the inconvenience brought.
Other features and advantages of the present invention are described in detail in embodiment part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification, is used from explanation the present invention, but is not construed as limiting the invention with embodiment one below.In the accompanying drawings:
Fig. 1 is the flow chart according to the chain processing method in the preferred embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the nouns of locality be included in term such as " upper and lower, inside and outside " only represents the orientation of this term under normal service condition, or being commonly called as those skilled in the art's understanding, and should not be considered as the restriction to this term.
See Fig. 1, the invention provides a kind of chain processing method, comprising:
(1) steel plate is cut into polylith inner plate raw sheet and outer plate raw sheet;
(2) on inner plate raw sheet and outer plate raw sheet, multiple mounting hole is all drilled with to form inner plate and outer plate;
(3) double end rivet is greater than the end of double end rivet bore with the bore at the middle part making double end rivet is processed;
(4) two ends of two inner plates are sheathed on the end of double end rivet by mounting hole, then two outer plates are sheathed on the end of double end rivet, then double end rivet is processed into riveted joint to form chain unit;
(5) two ends of multiple chain unit are formed the chain of ring-type by double end rivet successively movable riveted joint.
Pass through technique scheme, connection between the chain unit of chain is connected by pin and changes over rivet activity riveted joint, and bore rivet being processed into middle part is greater than the bore of end, decrease when chain rotates, mutual rotation between chain unit is to the radial force suffered by the wearing and tearing of joint and movable rivet of riveting, extending the working life of chain, avoiding frequently changing chain to producing the inconvenience brought.
In above-mentioned course of working, in order to when outer plate and inner plate connection state bad (as bending in double end rivet or cracking etc.), the link of timely both replacings, while time saving and energy saving, ensure that the transmission operation of chain is normal, be therefore all drilled with multiple mounting hole by inner plate raw sheet and outer plate raw sheet; Due to outer plate raw sheet having multiple mounting hole, in order to increase the mechanical strength of the outer plate after processing, preferably, this outer plate raw sheet is polygonal panel.
In the process of assembling at chain, transport or keeping in repair, multiple angles of polygonal panel are very sharp-pointed, easy scuffing maintenance man or the component hurt around it, in order to avoid the generation of this situation, preferred steps (2) also comprises: the wedge angle of outer plate raw sheet is machined to rounded corners.
In above-mentioned steps (3), in order to simplify the processing to double end rivet, save the production time, increase work efficiency, preferred double end rivet is spindle structure.
In addition, in order to reduce the rubbing contact area between chain and sprocket wheel, increase flexibility during chain operation, the working life of further prolongation chain, preferably, be solid of rotation in the middle part of double end rivet, the end of double end rivet is cylindrical body, and the bus of solid of rotation is the curve of indent and the end radius of solid of rotation is greater than cylindrical end radius.Like this, the inner concave curve that the sprocket on sprocket wheel can nail on this double-headed riveting better matches, and the situation of de-chain not easily occurs.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technological scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different mode of execution of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
