Abstract
The utility model relates to a shock absorber lower bracket horizontal punching die, which is provided with a die holder arranged on a punch worktable; a workpiece support base for clipping workpieces is arranged at the central part of the die holder; movable die components are symmetrically arranged at both sides of the workpiece support base; and extrusion slots matched with a press head are arranged between the die components and the die holder. Through the wedge-type press head arranged on a press, the die enables the vertical force of the press to be transformed into the horizontal force so as to realize the shock absorber lower bracket horizontal punching, thereby greatly enhancing the punching accuracy and efficiency. Compared with the prior art, the shock absorber lower bracket horizontal punching die has smart design and convenient operation, which can ensure the processing accuracy and is suitable for mass production.
Description
Technical field
The utility model belongs to machining appurtenance technical field, especially for a kind of transversal punching die tool of shock absorber lower carriage punching.
Technical background
In the prior art, the processing of four installing holes of shock absorber lower carriage is generally finished on drilling machine, for the installation accuracy that guarantees to be connected with automobile chassis, must hole on drilling machine after lower carriage and shock absorber assemble again.Because drilling machine boring is vertical processing, and can only bore a hole at every turn, therefore location difficulty not only, working (machining) efficiency is low, is difficult to satisfy batch production requirement, and the hole shape bit error that gets out is big, precision is low, bring inconvenience to auto assembly, fastness is installed does not also reach requirement.
The content of utility model
The purpose of this utility model provides a kind of simple to operate, quick practicality of processing, can effectively solve the problem of shock absorber lower carriage installing hole machining accuracy difference, and can improve the shock absorber lower carriage transversal punching die tool of working (machining) efficiency.
Realize that the technical scheme that the purpose of this utility model is taked is: this mould has a die holder that is installed on the stamping machine workbench, the centre of die holder is provided with the workpiece support that is used to clamp workpiece, the bilateral symmetry of workpiece support is provided with movably die assembly, is provided with the squeezing groove that cooperates with pressure head between two side shields of die assembly and die holder.
Described pressure head is the voussoir shape that the bottom has the inclined-plane.
Described die assembly is to be become by punch holder, drift, die plate and compression spring set, and wherein, drift is contained on the punch holder, and with die plate on the drift pilot hole corresponding matching that is provided with, the compression spring between punch holder and die plate,
Be provided with return spring between described die plate and the workpiece support.
Described die plate bottom is provided with the workpiece positioning boss.
The shock absorber lower carriage transversal punching die tool of making according to such scheme, by the Wedge-type pressure head of installing on the forcing press, the vertical force of forcing press is converted to horizontal force and realizes the horizontal punching of shock absorber lower carriage having improved punching precision and punching efficient thus greatly.Compared with prior art, have design concept ingenious, convenient to operation, can guarantee machining accuracy, be suitable for advantages such as batch process.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, each label is respectively among the figure: die holder 1, pressure head 2, punch holder 3, drift 4, die plate 5, shock absorber 6, shock absorber lower carriage 7, secondary compression spring 8, baffle plate 9, squeezing groove 10, workpiece support 11, return spring 12, main compression spring 13, drift pilot hole 14, positioning boss 15.
The utility model shock absorber lower carriage transversal punching die tool, has a rectangle die holder 1 that is installed on the stamping machine workbench, the axis position of die holder 1 is provided with the workpiece support 11 that is used to clamp shock absorber 6, the bilateral symmetry of workpiece support 11 is provided with two groups of movably die assemblies, the two ends of die holder 1 have baffle plate 9, are respectively equipped with the squeezing groove 10 that cooperates with stamping machine pressure head 2 between die assembly and two baffle plates 9.Stamping machine pressure head 2 has the voussoir shape on inclined-plane for the bottom, and when pressure head was mobile vertically downward, its lower end contract went in the squeezing groove 10, and realizes the punching that moves horizontally of punch holder 3 and drift 4 by its extruding.Die assembly is made up of punch holder 3, drift 4, die plate 5, main compression spring 13 and secondary compression spring 8, wherein, four drifts 4 are packed in respectively on two punch holder 3, be provided with drift pilot hole 14 on two die plates 5, drift 4 and these drift pilot hole 14 corresponding matching, and can be in pilot hole moving telescopic, main compression spring 13 and secondary compression spring 8 lay respectively between punch holder 3 and the die plate 5, be provided with return spring 12 between die plate 5 and the workpiece support 11, be used for resetting of die plate 5; Two die plate 5 bottoms respectively are provided with 2 workpiece positioning boss 15, and the location when being used for clamping shock absorber lower carriage 7 is to guarantee the positional precision of punching processing.
The operation principle of this mould is: when carrying out punching processing, can be seated on the workpiece support 11 shock absorber 6 for the treatment of the punching lower carriage is housed, the openend of U-shaped lower carriage is installed on the both sides of workpiece support 11, and its end is contacted with workpiece positioning boss 15, its contact-making surface can guarantee positional precision and its interchangeability of punching reliably as the location benchmark of punching.Operating pressure machine then, two voussoir shape pressure heads 2 that have the inclined-plane are moved down rapidly, its lower end contract is gone in the squeezing groove 10, and under the voussoir effect, rely on the support of the baffle plate 9 at die holder 1 two ends, punch holder 3 and drift 4 are moved in the middle of die holder 1 fast, and, die plate 5 is pressed on the plane at shock absorber lower carriage 7 punching positions by the pressure of major and minor compression spring 13,8.This moment, two punch holder 3 and drift 4 continued fast moving, can go out four installing holes on the damper lower carriage 7 in moment.After finishing punching, 2 of pressure heads withdraw from squeezing groove 10 rapidly, punch holder 3 and drift 2 are return original position under the pressure effect of major and minor compression spring 13,8, die plate 5 also breaks away from shock absorber lower carriage 7 under the pressure of return spring 12 simultaneously, just can take off shock absorber 6, promptly finish the punching of a workpiece.
