Abstract
The present invention discloses hot forming wheel spoke technology which comprises the following steps: baiting, chamfering, winding circles, welding, grinding, enlarging, heating, forming, turning center holes, punching vent holes, punching screw holes, turning planes and end surfaces, finishing and packaging. Wheel spokes produced by the technology can enhance the utilization rate of steel material, reduce production cost, enhance economic benefit, strengthen stretching resistance and bend resistance strength simultaneously and prolong the service life.
Description
Technical field
The present invention relates to a kind of processing technology of spoke, relate in particular to a kind of hot forming process for spoke.
Background technology
Wheel is between tire and axletree, bear the rotary components of load, it is made up of two critical piece steel rings and spoke usually, spoke is at the support unit between axletree and wheel rim on the wheel, therefore the quality of spoke performance directly influences the ruuning situation and the security situation of vehicle, also directly influences the bearing capacity of vehicle simultaneously, reports, freight car wheel plate hole severe crack becomes the major failure that influences the lorry utilization in recent years.Also there is this situation in other vehicles.
At present, what the domestic production spoke all adopted is cold pressing forming process, and this technology is lower to the utilization rate of steel, it is higher that production cost is compared, poor on performance, easily ftractures from screw hole when vehicle transships, its stretch-proof, flexural strength are low, and service life is shorter.
Summary of the invention
In order to solve the shortcoming that above-mentioned cold pressing forming process exists, the invention provides a kind of thermoforming process of making spoke, the performance of spoke is improved, more help the use of vehicle.
Technical scheme of the present invention is achieved in that a kind of hot forming process for spoke, may further comprise the steps:
(1), blanking: use plate shearing machine to become the billot shape under the raw material;
(2), chamfering: use abrasive machine that the billot both ends of the surface are opened 45 degree grooves;
(3), Volume circle: use the Volume circular knitting machine with billot Volume circle;
(4), welding: two bevel ends are welded with dioxo gas protection weldering;
(5), mill processing: use abrasive machine with the weld grinding;
(6), expanding: the blank material expanding that step (5) obtains is round with the 315T hydraulic press;
(7), heating: use reverberating burner that circle is heated to 450-550 ℃;
(8), moulding 1: use the 315T hydraulic press with the moulding of heat circle flange;
(9), moulding 2:500T hydraulic press, with moulding rounding type;
(10), car mesopore: use lathe will justify car to requiring size;
(11), towards the wind hole: use the 160T punch press, towards spoke wind hole;
(12), towards screw hole: use the 160T punch press, towards screw hole;
(13), facing end face: the outerplanar and the end face that use lathe wheel spoke;
(14), finishing packing.
Compared with prior art the invention has the beneficial effects as follows:
1, improves the utilization rate of steel, the steel utilization ratio of the spoke of cold pressing forming process production is 72%, the steel utilization ratio of the spoke of hot-forming process for spoke production is 94%, every production a slice spoke new technology is saved steel 10.4Kg than old technology, the whole nation can be saved 20.35 ten thousand tons of steel so save raw material every year, every production a slice spoke can reduce production costs 15.00 yuan, can save 9.5 hundred million yuans in 1 year;
2, the spoke of old technology production, when transshipping, vehicle easily ftractures from screw hole, the main force part of spoke (being centre bore) that hot forming process for spoke (is example with the 14mm raw material) is produced has thickeied 0.4mm, installed surface has been thickeied, its stretch-proof, flexural strength have also improved, and obviously durability has strengthened;
3, remaining crooked, the internal stress that stretches in the spoke of old technology cold moudling, the spoke of explained hereafter of the present invention is through heat treatment, unstressed stack, no residualinternal stress, improve the bearing capacity of spoke, prolonged the service life of spoke, reduced driving accident, reduced maintenance frequency, economic benefit is conspicuous.
The specific embodiment
Below the present invention is described in further detail, use plate shearing machine to become the billot shape under the steel raw material; Use abrasive machine that the billot both ends of the surface are opened 45 degree grooves; Use the Volume circular knitting machine with billot Volume circle; With dioxo gas protection weldering two bevel ends are welded; Use abrasive machine with the weld grinding; With the 315T hydraulic press that the blank material expanding that step (5) obtains is round; Use reverberating burner that circle is heated to 500 ℃; Use the 315T hydraulic press with the moulding of heat circle flange earlier; Use the 500T hydraulic press again, with moulding rounding type; Use lathe will justify car to the requirement of actual application size; Use the 160T punch press, towards spoke wind hole; Use the 160T punch press, towards screw hole; Use the outerplanar and the end face of lathe wheel spoke; The manual amendment packing.
Claims (1)
