Description
Technical field
The present invention relates to aluminum sheet process equipment field, be specifically related to the hemmer of a kind of car aluminum heat shield processed.
Background technology
Aluminum sheet has the technological requirement of flange usually in process, particularly such as automobile engine aluminum heat shield; after the processing of edge flanging process; the mechanical strength at its edge can be significantly increased, and obtains service life prolonging, and has in addition the advantage of sharp edge abate.
Automobile engine aluminum heat shield flange is to adopt the punching block Sheet Metal Forming Technology to finish traditionally, because aluminum heat shield product volume is larger, therefore need corresponding large volume mould and press machine tool, processing safety is not good, and cause this explained hereafter cost higher, and traditional punching block Sheet Metal Forming Technology needs three orders to finish, and production efficiency is lower.
Summary of the invention
The object of the present invention is to provide the hemmer of a kind of car aluminum heat shield processed, can reduce the production cost of aluminum sheet flanging process, and enhance productivity.
To achieve these goals, the technical scheme of the present invention's proposition is:
The hemmer of a kind of car aluminum heat shield processed, comprise base, be positioned at base top vertical staking punch moving up and down, connect vertical staking punch the first cylinder, be positioned at the horizontal staking punch that the base upper right side can move horizontally, the second cylinder of the horizontal staking punch of connection; Be provided with step on the described base, described vertical staking punch bottom righthand side is provided with the wedge shape projection; The aluminum sheet that is used for flange is positioned over base, the flange position of described aluminum sheet is positioned on the step of base, described vertical staking punch bottom right-hand member is positioned at the left side of step top left, and described horizontal staking punch bottom level is more than or equal to the step overhead height.The horizontal range of preferred described vertical staking punch bottom right-hand member and step top left equals the thickness for the aluminum sheet of flange, and described horizontal staking punch bottom level is consistent with the step top.Under the effect of the first cylinder, vertical staking punch is stamped on the aluminum sheet, makes the flange position of the aluminum sheet at step place that deformation occur, and forms a right angle or obtuse angle; Start the second cylinder by travel switch simultaneously, under the effect of the second cylinder, horizontal staking punch is stamped on the obtuse-angulate flange of the aluminum sheet shape position, makes the flange position of aluminum sheet form the acute angle of spending less than 45; Under the drive of the second cylinder, horizontal staking punch resets, and starts simultaneously the first cylinder, and under the effect of the first cylinder, vertical staking punch resets; Taking off the aluminum sheet that vertical staking punch takes up is put back on the base; Under the drive of the first cylinder, vertical staking punch is stamped on the flange position of aluminum sheet again, makes the acutangulate aluminum sheet flange of shape position entirely finish flange.
As the hemmer of the further improved a kind of car aluminum heat shield processed of the present invention, the shoulder height on the described base equals the thickness for the aluminum sheet of flange.The height of step is not enough, can cause aluminum sheet deformation not obvious; The excessive height of step, the height of meeting limit levels staking punch makes flange position stress point too high, and the bending radius of the radian of formation is larger, is unfavorable for subsequent operation and flange quality; Draw preferred shoulder height by actual production and equal thickness for the aluminum sheet of flange.
As the hemmer of the further improved a kind of car aluminum heat shield processed of the present invention, the wedge shape of the described vertical staking punch bottom righthand side setting projection upper and lower surface angle number of degrees are 20 °～40 °.The wedge shape projection upper and lower surface angle number of degrees are excessive, and the acute angle number of degrees that the flange position forms are excessive, are unfavorable for again finishing of press work of follow-up vertical staking punch; The wedge shape projection upper and lower surface angle number of degrees are too small, and then the mechanical strength of wedge shape projection is difficult to guarantee that fall short of service life; Drawing the preferred wedge shape projection upper and lower surface angle number of degrees by actual production is 20 °～40 °.
As the hemmer of the further improved a kind of car aluminum heat shield processed of the present invention, described horizontal staking punch lower-left end is provided with wedge-shaped indentation.The identical lifting surface area that can effectively increase aluminum sheet flange position with the wedge shape convex shape of wedge-shaped indentation can effectively be avoided the problem of the stressed aluminum sheet stress point distortion that causes of small size, thereby improve flange effect and quality.
As the hemmer of the further improved a kind of car aluminum heat shield processed of the present invention, described wedge-shaped indentation matches with the wedge shape projection, and its shape is identical.Wedge-shaped indentation is identical with the wedge shape convex shape can to reduce the bending radius of the radian at flange position further, thereby improves flange effect and quality.
Hemmer as the further improved a kind of car aluminum heat shield processed of the present invention also comprises the neonychium that is positioned on the aluminum sheet, and the thickness of described neonychium equates with the thickness of the aluminum sheet that is used for flange.The effect of neonychium is to control the punching press terminal point of vertical staking punch, has avoided the separately excessive and sheet material damage of the stressed punching press that causes of flange position, has reduced the scrappage of punching press flange.
The hemmer of a kind of car aluminum provided by the present invention heat shield processed, the self-powered press machine tool that need not, handling safety is simple, weak point consuming time, operation are few, and flange effect and quality are good, and the flange scrappage is low, can reduce the production cost of aluminum sheet flanging process, and enhance productivity.
