Detailed description of the invention

In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below will knot Close specific embodiment this programme is discussed in detail further.

As shown in Figures 3 to 8, a kind of Trimming Die that this utility model embodiment provides, it includes Upper mold deburring insert 31, for the die clamp 21 that is connected with upper bolster, wherein, upper mold deburring insert First end of 31 removably connects with die clamp 21；Fit with die clamp 21 in upper mold deburring insert 31 One side be installed surface 34, in upper mold deburring insert 31, the one side in remotely mounted face 34 is deburring face 35； Second end of upper mold deburring insert 31 is for carrying out deburring to U-shaped part, and the termination 33 of the second end is V Type structure；Installed surface 34 at termination 33 includes the first inclined-plane 36 and the second inclined-plane 37, and first is oblique Face 36 and the second inclined-plane 37 35 are extended to deburring face by the medium position of installed surface 34 respectively.Permissible Being understood by, the Trimming Die that this utility model embodiment provides also includes for carrying out U-shaped part solid Fixed lower mold deburring insert 41.

The Trimming Die that this utility model embodiment provides, the end of the second end of its upper mold deburring insert 31 33 i.e. trimming edge is V-structure so that this upper mold deburring insert 31 can with by centre to two The mode on limit repaiies the base plate of disconnected U-shaped part, and is the ability sidewall to U-shaped part after the deburring of base plate completes Carry out deburring, there is at this termination 33 first inclined-plane 36 and the second inclined-plane 37 simultaneously, preferably avoid Deburring quality is impacted, so that this Trimming Die exists by the installed surface 34 at this termination 33 It is not likely to produce burr during deburring, and then makes its deburring quality preferable.Due to of the present utility model Upper mold deburring insert 31 removably connects with die clamp 21, so that the dimension of this upper mold deburring insert 31 Repair more convenient.

Specifically, die clamp 21 can be provided with the installation for matching with upper mold deburring insert 31 Groove 23, the bottom of mounting groove 23 and upper mold deburring insert 31 are provided with corresponding insert installing hole 32, thus conveniently realized removably connecting between upper mold deburring insert 31 and die clamp 21, make The maintenance of upper mold deburring insert 31 and change more convenient, reduce the exploitation of mould and keep in repair into This, can carry out the most spacing to upper mold deburring insert 31 by the two side of mounting groove 23 simultaneously, It is effectively prevented upper mold deburring insert 31 during deburring, glances off phenomenon.It is understood that In order to make the connection between upper mold deburring insert 31 and die clamp 21 more firm, upper mold deburring insert 31 Can have two insert installing holes 32, two insert installing holes 32 can be along upper mold deburring insert 31 Bearing of trend arrange.

Further, die clamp 21 can be provided with the die clamp installing hole for being connected with upper bolster 22, it is achieved thereby that removably connecting between die clamp 21 and upper bolster so that the maintenance of die clamp 21 More convenient with changing.

In another embodiment of the present utility model, the first inclined-plane 36 and the second inclined-plane 37 can be about The longitudinal centre line of upper mold deburring insert 31 is symmetrical, so that the both sides of termination 33 have identical Intensity and the most not easy fracture.It should be noted that the extension that longitudinal direction herein is upper mold deburring insert 31 Direction.

As it is shown in figure 5, in order to ensure that the Trimming Die that this utility model embodiment provides has preferably Deburring quality, forms the first angle a, the first angle a between the first inclined-plane 36 and the second inclined-plane 37 Angle be 148 degree～156 degree.In actual applications, this first angle a can be preferably 152 degree, Now on the first inclined-plane 36 and the second inclined-plane 37 away from above-mentioned longitudinal centre line while with deburring face it Between angle that is the 3rd angle c be 26 degree.

It addition, the angle between the dual-side of V-structure is the second angle b, the angle of the second angle b It it is 144 degree～148 degree, in actual applications, it may be preferred to be 146 degree.It is understood that V The tip of type structure is positioned on the longitudinal centre line of upper mold deburring insert 31, and its dual-side is about this longitudinally Centrage is symmetrical, the most just two side to U-shaped part can carry out deburring and complete deburring simultaneously simultaneously Process.

The general deburring process of the Trimming Die that this utility model embodiment provides is: upper mold deburring insert 31 move to the direction near lower mold deburring insert 41, make the most advanced and sophisticated of V-structure and U-shaped part (figure Not shown in) the middle part of base plate contact and start deburring, as shown in Figure 6；Upper mold deburring is inlayed Block continues to move downward so that the dual-side of V-structure two side with U-shaped part respectively contacts and opens Beginning deburring, as shown in Figure 7；Upper mold deburring insert is further continued for moving downward, until completing U-shaped part The deburring work of two side, as shown in Figure 8.

The above is only preferred implementation of the present utility model, it should be pointed out that these are implemented Example is merely to illustrate this utility model rather than limits scope of the present utility model, and, reading After content of the present utility model, this utility model can be made respectively by relevant technical staff in the field Planting and change or amendment, these equivalent form of values fall into the model that the application appended claims is limited equally Enclose.
