Abstract
The utility model discloses a chain hinge pin machining production line which comprises a cold header, a centrifugal machine A, a hot water pool, a centrifugal machine B and a thermal treatment furnace. A shearing station, a first heading station, a second heading station and a reshaping and discharging station are arranged on the cold header in sequence. A shearing die is installed on the shearing station. A cold heading die A is installed on the first heading station. A cold heading die B is installed on the second heading station. A reshaping die is installed on the reshaping and discharging station. The cold header is further provided with a transportation tool. Hinge pins are transported through a transporter between the cold header, the centrifugal machine A, the hot water pool, the centrifugal machine B and the thermal treatment furnace. According to the technical scheme, an existing cold header is transformed, and the transformed cold header has the functions of shearing hinge pin blanks and heading R corners. In this way, the R corners of the hinge pins are extruded and formed through the dies, follow-up barreling does is not needed, quality can be effectively controlled, and environmental pollution is reduced greatly.
Description
Technical field
The utility model belongs to field of chains, relates in particular to a kind of chain hinge pin machining production line.
Background technology
The R angle (chamfering) of chain hinge pin as chain in assembling process, guide effect when bearing pin and outer plate interference fit and existing, the quality at bearing pin R angle will cause bearing pin packing the quality problems that in outer plate process occur the excision of chain plate hole finally to affect chain fatigue behaviour into.The bearing pin R of chain manufactures the method for rolling together with abrasive material, mutually rubbing and clashing into that always adopts at drum.Although this method is simple, the bearing pin R poor stability processing, judged by operating personnel affects greatly, and stock utilization is low.And, due to such processing, causing a large amount of generations of sewage sludge, disposal cost is expensive, does not more meet the requirement of recycling economy.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of chain hinge pin machining production line, and existing cold headers are reequiped, and makes it possess shear pin axis blank and upsetting R angle function.Like this, bearing pin R angle is the extrusion molding by mould, does not follow-uply need to carry out barrel finishing, and not only quality can be effectively controlled, and greatly reduces environmental pollution.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of chain hinge pin machining production line, comprises cold headers, centrifuge A, hot-tub, centrifuge B and heat-treatment furnace, on described cold headers, be provided with successively shearing station, the first heading station, the second heading station and shaping discharging station, shearing die for long material being cut into bearing pin blank is installed on shearing station, cold upsetting die of car A for one end of bearing pin blank being carried out to cold-heading processing is installed on the first heading station, cold upsetting die of car B for the other end of bearing pin blank being carried out to cold-heading processing is installed on the second heading station, shaping mould for bearing pin blank being carried out to shaping is installed on shaping discharging station, described cold headers are provided with for clamping pin axis blank and by it and are shearing station, the first heading station, the handover frock of transferring between the second heading station and shaping discharging station, the port of export of described cold headers arranges conveying device A, conveying device A delivers to the bearing pin blank of collection for getting rid of oily centrifuge A, the port of export of centrifuge A arranges conveying device B, hot-tub delivered to by the bearing pin blank of collection by conveying device B, the port of export of hot-tub arranges conveying device C, the centrifuge B for water dumping delivered to by the bearing pin blank of collection by conveying device C, and the port of export of centrifuge B arranges conveying device D, and heat-treatment furnace delivered to by the bearing pin blank of collection by conveying device D.
As preferably, described conveying device A, conveying device B, conveying device C and conveying device D include and collect frame and delivery track.
The utility model, owing to having adopted above technical scheme, is reequiped existing cold headers, makes it possess shear pin axis blank and upsetting R angle function.Like this, bearing pin R angle is the cold-extrusion shaping by mould, does not follow-uply need to carry out barrel finishing, and not only quality can be effectively controlled, and greatly reduces environmental pollution.The utility model, cuts off material with upsetting R angle and is incorporated on same equipment and completes, and eliminated the carrying of former inter process, has eliminated the generation of rolling processing sewage and mud, has promoted the utilization rate of material simultaneously.
