Description
Technical field
The present invention relates to a kind of manufacturing installation of auto parts, specifically, relate to a kind of anchor clamps of making the automobile steering device upper bracket.
Background technology
Along with expanding economy and growth in the living standard, the use amount of automobile increases year by year.Vehicle is for the mankind's the relation interwoveness of very can saying so, and between vehicular manufacturer, vehicle spare part manufacturer and driver, not only pursues the performance of vehicle itself, security with and fuel-efficient effect, and also more and more pay attention to for the assembly of automobile.
The main vehicles that become us at automobile simultaneously, people to its manufacturing process want the more and more higher of changes persuing, make that its production technology also is more and more advanced, the production of various parts and detect also thereupon more and more advanced person, precision is more and more higher.Steering gear upper bracket profile complexity, three dimensions size are many, and the various installations room size of its requirement all will guarantee in the dimensional tolerance range that allows, the performance of its accuracy affects automobile.
Anchor clamps are mainly used in the school shape in the part manufacturing, school shape is meant that workpiece is behind the various stamping procedures of process, because its dimensional accuracy and surface configuration can't reach the requirement of part, at this moment, just need be on the basis that its shape and size have required near part, make it produce little plastic deformation by special mould again, thereby obtain a kind of processing method for stamping of qualified parts.The purpose of school shape is the unevenness of surface of the work or circular arc to be trimmed to can satisfy the drawing requirement.In general, for surface configuration and the higher stamping parts of dimensional requirement, often all need to carry out school shape.School shape is in mechanical manufacturing field extensive uses such as automobiles.
School shape technology has following characteristics:
1, the deflection of school shape is all very little, and mostly is local distortion;
2, therefore the dimensional accuracy of school shape workpiece requires the precision of bearing of die correspondingly also should improve all than higher;
3, the stress the during shape of school, the character of strain all are different from the ess-strain of former procedures.Stress state during school shape should help reducing the influence of resilience to workpiece accuracy, promptly helps making workpiece shape and size stable under the shape mould effect of school.Therefore during the shape of school the residing ess-strain of workpiece than general forming process complexity many;
4, during the shape of school, all need carry out during at lower dead point position at press ram.Therefore, school shape is carried out on the smoothing press of special use usually to rigidity, the required precision height of use equipment.If carry out school shape, then must be provided with overload protection arrangement, in case damage equipment at ordinary press.
Crossbeam is the vehicle key parts, and fascia crossbeam especially, fascia crossbeam are to guarantee stable, the reliable strength member that uses of the various instrument of automobile, comprise crossbeam, sheet metal and installing hole.Rotation of the high speed of high-power engine and vehicle the abominable of road conditions of travelling caused powerful vibration to driver's cabin easily and jolts, thereby causes in the preceding control panel appliance circuit and partial function to open circuit or malfunctioning.
Conventional brace is that the pedestal and the metallic support that are welded by steel plate or steel pipe are structural member, owing to adopt integral plate or steel pipe welded structure, makes anchor clamps very heavy, is difficult for mobile.Traditional straightening method is to use anchor clamps crossbeam is detected, if pin gauge can pass the installing hole on the crossbeam and meet with the aperture, then product is qualified, if the rule pin can not pass the installing hole on the crossbeam, then need to be fixed on the anchor clamps, tool using is corrected.This process need needs to use the double time through the two procedures of anchor clamps and anchor clamps.
Summary of the invention
The present invention be directed to when making the steering gear upper bracket in the prior art, school shape operation to operating personnel require that height, school shape time are long, problem such as expense energy, school shape efficient are low, and a kind of cost performance height, simple to operate, the school shape anchor clamps of automobile steering device upper bracket have fast been proposed.
