Description
Technical field
The present invention relates to the forming technique of Self Drilling Screws, more particularly to a kind of geometrical clamp for tommy bar tail mould
Tool.
Background technology
The shaping of Self Drilling Screws is about divided into two parts, and a part is to twist out screw thread by threading machining, and end section is then
By special processing mold compression molding, the shaping of wherein drilling tail part is that Self Drilling Screws end is two symmetrical mould moulds
It is molded.First then both are combined again, with the matrix and drilling tail shaping position of unlike material processing and fabricating mould to make respectively
It is used as the mould of production Self Drilling Screws, this is current more advanced technology of die manufacturing.
Technology as shown in Application No. 201310020671.X patent, disclose a kind of using similar Making mold
The tommy bar tail mould of technology.Mould disclosed in the patent, generally pressed closer and be fixed on pedestal by screw, such as Fig. 1
It is shown.The technical scheme of this fixing mould comes with some shortcomings, i.e., use, which is pressed closer mould by screw, is fixed on pedestal
Mode, the firmness that mould is fixed on pedestal is not big enough.In the course of the work, mould is per minute by up to 600
Secondary shock, easily cause mould left and right it is small rock, so as to cause to be loosened between die and die holder, so as to cause stability
It is deteriorated, the shock number that mould is born is substantially reduced the mold use life-span less than 1,000,000 times, it is impossible to meets production
Demand.
The content of the invention
The shortcomings that for above-mentioned prior art, the present invention provide a kind of stationary fixture for tommy bar tail mould and come
Solve these problems.The technical scheme that the present invention takes is as follows.
A kind of stationary fixture for tommy bar tail mould, it is characterised in that including pedestal, compact heap, mould and
Bottom fixed block, wherein, the groove for placing compact heap is offered on the pedestal, compact heap is placed in the groove and passes through spiral shell
Bolt fastens and is close to mould；Mould fixing port is further opened with the pedestal, mould is placed in the mould fixing port of pedestal and tight
It is pressed on the fixed block of bottom, bottom fixed block is fastened by bolts in pedestal lower end.
Further, the depth of the groove is slightly larger than the height of compact heap.
Further, the width of the bottom of the groove is slightly less than the width of the bottom surface of compact heap.
Further, the bottom of the groove offers two bolts hole.
Further, two bolts hole are offered on the compact heap, the two bolts hole bottom with the groove respectively
Two bolts hole it is corresponding.
Further, the one side of the compact heap is opened up as inclined-plane.
Further, the mould is made up of die and die holder.
Further, the top side of the mould offer common to a die and die holder and with the positive phase of mould
Vertical inclined-plane, its angle of inclination are identical with the angle of inclination on the inclined-plane on the compact heap.
Further, the inclined-plane of compact heap presses the mould inclined-plane, mould is pressed on another inner side of mould fixing port
On the fixed block of bottom.
Different from mould to press closer to the technology being fixed on pedestal by screw, the present invention is by compact heap by mould
It is fixed on pedestal.Because the height of compact heap is less than the depth of groove, and the width of the bottom surface of compact heap is slightly larger than the bottom of groove
Width, and the angle of inclination on the inclined-plane of compact heap is identical with the angle of inclination on mould inclined-plane, so compact heap can pass through inclined-plane
Fully pressing mould, compact heap can be pressed onto the joint portion of die holder and die and die holder and die simultaneously, mould is fully fixed,
Stability is stronger, will not produce it is small rock, loosening will not be also produced between die and die holder.According to the present invention, mould can be held
The number being impacted improves two 3 times, and the mold use life-span is extended, thus the present invention can more meet to produce needs.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with the accompanying drawings and embodiment, it is right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
As shown in Fig. 2 the present embodiment includes pedestal 6, compact heap 7, mould 8, the wherein part of bottom fixed block 9 four, mould 8
It is made up of die 10 and die holder 11.
As shown in figure 3, offering the groove 12 for placing compact heap 7 on pedestal 6, the depth of groove 12 is slightly larger than compact heap 7
Height, and the width of the bottom of groove 12 is slightly less than the width of the bottom surface of compact heap 7, and the bottom of groove 12 offers two bolts hole
13。
As shown in figure 4, mould fixing port 14 is offered on pedestal 6.
As shown in figure 5, mould 8 is made up of die 10 and die holder 11, the upper left-hand of mould 8 offers an inclined-plane 15, tiltedly
Face 15 is common to die 10 and die holder 11, and perpendicular to the front of mould 8.
As shown in Figure 6, Figure 7, the right flank of compact heap 7 is opened up as inclined-plane 16, its angle of inclination and the ramp 15 of mould 8
Angle of inclination is identical, to enable the inclined-plane 16 of compact heap 7 to be close to mould inclined-plane 15.
As shown in fig. 6, offer two bolts hole 17 on compact heap 7, the two bolts hole 17 respectively with the bottom of groove 12
Two bolts hole 13 are corresponding.
In practical application, as shown in Figure 9, Figure 10, bottom fixed block 9 is fastened by bolts in the lower end of pedestal 6；Will
Die holder 11 and the combination of die 10 fix, and are combined into mould 8, then mould 8 is put into the mould fixing port 14 of pedestal 6；Will
Compact heap 7 is put into groove 12, and the inclined-plane 16 of compact heap 7 is pressed into mould inclined-plane 15, is made compact heap 7 while is close to be pressed onto die holder 11
With the joint portion of die 10 and die holder 11 and die 10, mould 8 is set to be close to another inner side and bottom for being pressed in mould fixing port 14
Hold on fixed block 9, two on compact heap bolts hole 17 is used after being alignd respectively with two bolts hole 13 of the bottom of groove 12
Compact heap 7 is fastened in groove 12 by bolt.Mould is combined with pedestal to overall top view, front view and the bottom after fixing
View is respectively as shown in Figure 11, Figure 12 and Figure 13.
In the present embodiment, because the height of compact heap 7 is slightly less than the depth of groove 12, and the width of the bottom surface of compact heap 7
Slightly larger than the width of the bottom of groove 12, and the angle of inclination on the inclined-plane 16 of compact heap 7 is equal with the angle of inclination on mould inclined-plane 15,
So can fully press mould 8 by the compact heap 7 of inclined-plane 16, compact heap 7 can be close to be pressed onto simultaneously die holder 11 and die 10 and
The joint portion of die holder 11 and die 10, makes mould 8 be securely fixed on pedestal 6, stability is stronger, will not produce small rolling
It is dynamic, loosening will not be also produced between die 10 and die holder 11, thus mould 8 is born stronger shock, enable mould 8
The number for bearing to hit is greatly improved, and service life is extended, and can preferably meet production requirement.
Embodiment described above only expresses embodiments of the present invention, and its description is more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
