Detailed description of the invention

In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.

As Figure 1-3, a kind of U-shaped punch forming module, comprises upper die unit, lower die unit and discharging unit, upper die unit arrange with lower die unit immediately below, discharging unit is located at the sidepiece of upper die unit, by the cooperation between three, realizes the automation mechanized operation of workpiece punching press.

Concrete, described upper die unit comprises cope match-plate pattern 11, top die 12 and the first actuator; Described top die 12 is fixedly connected on cope match-plate pattern 11 central part position, U-shaped for coordinating stamped workpieces to become with counterdie.Described cope match-plate pattern 11 can knee-action thus drive top die knee-action, and described first actuator is for driving cope match-plate pattern 11 knee-action stamped workpieces; Concrete, described first actuator is set to cylinder.Described lower die unit comprises lower bolster 21, dip mold 22 and bolster, and described dip mold 22 matches with stamped workpieces with top die 12; Concrete, offer stamped recess 13 bottom described top die 12, shape, the size of this stamped recess 13 are all equal with workpiece, and shape, the size of corresponding dip mold are also equal with workpiece.The first vallecular cavity 23 is offered in described lower bolster 21 corresponding top die 12 position, is provided with the second vallecular cavity 24 in the below of the first vallecular cavity 23, and described dip mold 22 one end is fixedly connected on bottom the second vallecular cavity 24 by joint pin 3, and the other end extends the first vallecular cavity 23 upper surface; Described first vallecular cavity sidewall is provided with semi-circular groove, and a roller 6 is rotating to be placed in this semi-circular groove; As preferably, the both sides central part outwardly convex of described roller 6 forms Rotational Cylindrical, and described semi-circular groove both ends offer the post groove for this Rotational Cylindrical accommodating, and shape and the Rotational Cylindrical of described post groove match; The diameter of post groove is slightly larger than the diameter of Rotational Cylindrical, thus when Rotational Cylindrical is placed in post groove, Rotational Cylindrical can be rotated by phase coupled columns groove.Roller 6 is arranged on the contact surface of top die and dip mold, and by the setting of roller 6, coordinate in the process of punching press at top die with dip mold, the friction between both sidewalls can reduce relatively, the service life of extension device.

In the process of punching press, the restoring force under bolster can apply top die, makes the top die strength needed for reply action upwards less, saves the energy consumption of cylinder; The speed moved upward is fast, increases work efficiency.Concrete, described bolster comprises bumper post 41, limited post 42, and described bumper post 41 is connected to the second vallecular cavity 24 bottom surface by spring 43, and described limited post 42 be that bumper post 41 both sides stretch out two projections of formation; When the downward punching press of top die, spring 43 is compacted, and bumper post moves down, and when top die moves, spring recovers original length, to top die applying active force upwards; When limited post 42 arrives the position that the first vallecular cavity 23 contacts with the second vallecular cavity 24, limited post can be blocked by the bottom of the first vallecular cavity 23, thus bumper post 41 moves on cannot continuing again, thus make spring 43 by excessive stretching, the service life of spring 43 can not be extended.

As preferably, be provided with discharging unit, thus realize the punching press of workpiece and the automation of discharging, pass through operating efficiency.Concrete, described discharging unit comprises that discharging cuts somebody's hair 51, fixed arm 52, second actuator 53 and discharge runner; Described discharge runner is arranged on the sidepiece of lower bolster.One end of described fixed arm 52 is fixedly connected on top die, the other end is fixedly connected on discharging and cuts somebody's hair 51, thus discharging is cut somebody's hair 51 be limited to corresponding stamped recess 13 position, described discharging is cut somebody's hair 51 can left and right action, thus punching press is completed the workpiece release be placed in stamped recess 13, push in discharge runner and skid off.Described second actuator 53 to be cut somebody's hair about 51 actions for driving discharging, and concrete, described second actuator 53 is cylinder.As preferably, described discharging end of cutting somebody's hair is provided with holding tank 511, and an elastic component 512 is placed in this holding tank 511, and wherein an end is fixed on bottom holding tank 511, and the other end stretches out holding tank 511 and connects a push pedal 513.

Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
