Abstract

The utility model provides a die forging of car connecting rod, includes the upper die base, module on the dovetailing has in the upper die base, and module under being equipped with below last module still includes the die holder, the die holder includes two half module seats and many bolts, and two half module seats pass through the detachable connection of bolt, are equipped with the recess on a terminal surface of half module seat, and lower module lies in between two half module seats to the both ends of module lie in the recess down, the to -be -solved technical problem of the utility model is to provide a maintenance is all very convenient with the change, and it is accurate to lead that die forging of car connecting rod, simple structure not only, the die holder is the components of a whole that can function independently with module down in addition.

Description

A kind of automobile connecting bar die forging

Technical field

The utility model belongs to field of machining, relates to a kind of automobile connecting bar die forging.

Background technology

Convex concave is made in the corner of existing automobile connecting bar forging die, so both mold materials was wasted for small mould, add man-hour time-consuming again, be unfavorable for again the reparation of mould simultaneously, and the counterdie of general automobile connecting bar and die holder are one, when changing counterdie, need integral replacing, it is not very convenient to operate.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of automobile connecting bar die forging, and not only structure is simple, and die holder and lower module are splits, maintenance and change all very convenient, and guiding precisely.

The technical solution of the utility model is: a kind of automobile connecting bar die forging, comprise upper bolster, in upper bolster, dovetail is connected with upper module, below upper module, be provided with lower module, also comprise die shoe, described die shoe comprises two and half die holders and Duo Gen bolt, two and half die holders are by the detachable connection of bolt, an end face of half die holder is provided with groove, and lower module is between two and half die holders, and the two ends of lower module are positioned at groove.

Further, locating hole is provided with in the side of half die holder.

Further, pad is provided with in the below of lower module.

Further, an end face of the close die shoe of upper bolster is provided with dovetail groove, and upper module is connected with upper bolster dovetail by dovetail groove, is provided with T-shaped key and drift in dovetail groove.

Further, the height of described half die holder is greater than the height of lower module.

The beneficial effects of the utility model are: die shoe can be fixed between two and half die holders by bolt, the height of half die holder is greater than lower module, one end of half die holder is made to protrude from lower module, after lower module clamps by two and half die holders, a gathering sill be made up of groove can be formed above lower module, can be good at the effect playing guiding, pad below, can be used for adjusting the height of lower module, upper bolster adopts dovetail to connect simultaneously, can make upper module after damage, can change timely; T-shaped key and drift can play the effect of location.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 is perspective view of the present utility model,

Fig. 2 of the present utility modelly partly cuts open schematic diagram,

Fig. 3 of the present utility modelly partly cuts open schematic diagram.

Detailed description of the invention

As shown in Fig. 1 to 3: a kind of automobile connecting bar die forging, comprise upper bolster 1, in upper bolster 1, dovetail is connected with upper module 2, below upper module 2, be provided with lower module 4, also comprise die shoe, described die shoe comprises two and half die holders 3 and Duo Gen bolt 5, two and half die holders 3 are by the detachable connection of bolt 5, an end face of half die holder 3 is provided with groove 32, and lower module 4 is between two and half die holders 3, and the two ends of lower module 4 are positioned at groove 32.

Further, locating hole 31 is provided with in the side of half die holder 3.

Further, pad 7 is provided with in the below of lower module 4.

Further, an end face of the close die shoe of upper bolster 1 is provided with dovetail groove 11, upper module 2 is connected with upper bolster 1 dovetail by dovetail groove 11, is provided with T-shaped key 8 and drift 6 in dovetail groove 11.

Further, the height of described half die holder 3 is greater than the height of lower module 4.

Using method of the present utility model: first lower module 4 is encased in die shoe, one piece of pad 7 can be placed in the below of lower module 4, then will utilize locating hole 31, and be fixed on by die shoe on the workbench of forcing press, upper bolster 1 is arranged on press ram; Press forcing press switch during forging, slide block moves downward, and first upper module 2 falls into the square frame that two pieces of die shoe inner groovies 32 surround and realizes positioning and guiding, and final and lower module 4 is fitted and compressed, and realizes die forging; Complete die forging rear slider and upwards promote return.
