Description
Technical field
The present invention relates to the bending technique and the device of metal parts, particularly a kind of bending and molding hardware stamping part method and system.
Background technology
In hardware stamping part is produced, usually to carry out a large amount of right angle bendings, require after the bending 90 ° ± 1.0 ° of angles, sometimes even be 90 ° ± 0.5 °, so that product can be guaranteed its tram when assembling.Because metal can produce elastic recovery after bending, the performance of the size of its recovery value and metal material itself has confidential relation, and maximum can reach about 10 °.Therefore, in order to overcome the spring-go angle after the bending, usually need when bending, compensate, or after bending, it be proofreaied and correct, to reach required angle to the spring-go angle.
Traditional bending, aligning gear are broadly divided into two big classes, though two class mechanism structure differences have a common characteristic, i.e. bending is carried out at two different workers stations with proofreading and correct, and this makes:
1) the mould molding action increases, and complexity improves, and cost improves.
Because mould must be provided with one and proofread and correct the worker station in the follow-up worker station at bender station, proofread and correct centering block or proofread and correct slide block accordingly thereby on template corresponding, increase the frame mouth and increase, make the material cost and the corresponding raising of processing cost of mould.
2) be not easy to maintenance.
At first, the mould complexity itself just is unfavorable for maintenance, and in factory's hardware mold repair process, manual operations has accounted for very big proportion, because mould is bigger, mold weight is heavy, thereby has increased die repair person's labour intensity.
3) be difficult to proofread and correct for some bending.
Traditional aligning gear only is suitable for the bending line parallel is proofreaied and correct in the bending of feed direction usually, to some special bendings then owing to the restriction that is subjected to die space is difficult to realize.
Summary of the invention
The object of the present invention is to provide a kind of bending and molding hardware stamping part method and system, the technical problem that the mainly existing bending of solution, aligning gear need carry out at two different workers stations has the good actual application effect.
For achieving the above object, technical scheme of the present invention is:
A kind of bending and molding hardware stamping part method is characterized in that it comprises the steps:
Step 1: clamp, by correcting mould lower surface and bending die upper surface workpiece is clamped, and below the correcting passage, expose and treat dogleg section;
Step 2: correcting, before beginning, must carry out correcting to centering block by having the correcting passage on the correcting mould to the workpiece bending, promptly necessary restriction is carried out in its rotation around Y-axis;
Step 3: bending, begin after the workpiece bending, bending power makes the correct bending gap of maintenance between centering block and bending die on the correction inclined-plane that the component of directions X is close to centering block to proofread and correct die;
Step 4: proofread and correct, after the workpiece bending finished, the centering block head entered the oblique rectifying plane of proofreading and correct die, under the effect of proofreading and correct the inclined-plane, centering block was counterclockwise rotated in the bending inclined-plane of bending die, finished the correction to workpiece.
A kind of bending and molding hardware stamping part system is used to implement the method for claim 1, and it is characterized in that: this comprises mould part and control section; Wherein: mould part is made of correcting mould, bending die, straightening die Renhe staking punch centering block; Have the correcting passage on this correcting mould, this staking punch centering block is positioned at this correcting passage, and its external diameter is slightly less than the internal diameter of correcting passage; The correcting passage below that die all is located at the correcting mould is proofreaied and correct in this bender Renhe, have the bending inclined-plane that down inwardly concaves gradually from the top on the working face of this bending die, the working face of this correction die has from the top correction inclined-plane that down outwards protrudes gradually; This control section is used to control the distance between the mould and the motion of drift.
Described bending and molding hardware stamping part system is characterized in that: this staking punch centering block bottom has protuberance near working face one side of proofreading and correct die.
By said structure, the present invention has following advantage:
The inventive method and device compared with prior art, can be on a mold once property finish the workpiece bending and two procedures is proofreaied and correct in bending, efficient height, cost are low.
Description of drawings
Fig. 1 is the structural representation of the inventive method.
Fig. 2 is the schematic diagram of the structure of mould part in the system of the present invention.
The specific embodiment
See also Fig. 2, the invention discloses a kind of bending and molding hardware stamping part system.As shown in the figure: this comprises mould part and control section (not shown); Wherein: mould part is made of correcting mould 1, bending die 2, correction die 3 and staking punch centering block 4; Have correcting passage 11 on this correcting mould 1, this staking punch centering block 4 is positioned at this correcting passage, and its external diameter is slightly less than the internal diameter of correcting passage 11; This bending die 2 and correction die 3 all are located at correcting passage 11 belows of correcting mould 1, have the bending inclined-plane 22 that down inwardly concaves gradually from the top on the working face 21 of this bending die 2, the working face 31 of this correction die 3 has from the top correction inclined-plane 32 that down outwards protrudes gradually; This control section is used to control the distance between the mould and the motion of drift.These staking punch centering block 4 bottoms have protuberance 41 near working face 31 1 sides of proofreading and correct die 3.
Please consult Fig. 2 in conjunction with Fig. 1 again, the step of the bending and molding method that the use said system is implemented is as follows:
Step 1: clamp
By correcting mould 1 lower surface and bending die 2 upper surfaces workpiece 5 is clamped, and below correcting passage 11, expose and treat dogleg section.
Step 2: correcting
