Utility model content
The purpose of this utility model is to provide a kind of T iron and takes out punch die, has solved production process and has easily occurred cylinder boring bias and the lower problem of working (machining) efficiency.
For achieving the above object, the utility model provides a kind of T iron to take out punch die, comprise patrix, counterdie, lower bolster, fixed head, buoyance lift spring, fixing thimble, material returning sleeve and material returned thimble, the bottom centre of described patrix convexes with salient point, described fixed head is fixed on the upside of described lower bolster, described counterdie is positioned at the top of described fixed head and described lower bolster, and described buoyance lift spring is supported between described counterdie and described lower bolster, the lower end of described fixing thimble is fixed on described fixed head, the upper end of described fixing thimble is stretched in the centre bore of described counterdie, the vertical center line of described fixing thimble overlaps with the vertical center line of described salient point, described material returning sleeve is movably set on described fixing thimble, described material returned thimble passes successively described lower bolster and described fixed head and its top and supports the bottom in described material returning sleeve.
Preferably, also comprise spacing collar, described spacing collar is fixed on described lower bolster upside, and described spacing collar top hooks the outer rim at described counterdie.
Preferably, also comprise the blowing nozzle that is connected to compressed air source, described blowing nozzle is positioned at the top of described counterdie.
Compared with prior art, T iron of the present utility model is taken out punch die owing to being provided with described fixing thimble, and convex with salient point in the bottom centre of described patrix, the vertical center line of the vertical center line of described fixing thimble and described salient point overlaps, thereby can make cylinder counterbore moulding together with center pillar mesopore of T iron product, and can guarantee the concentricity of counterbore and center pillar mesopore, the concentricity of counterbore and center pillar mesopore is reached in 0.05mm; In addition, take out by mould the mode that hole replaces drilling machine boring, not only can control internal diameter and the height of counterbore well, make the size of counterbore more stable, and it is faster to compare drilling machine process velocity, efficiency is higher, does not also produce waste material, thereby has saved cost.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the charging schematic diagram that the utility model T iron is taken out punch die.
Fig. 2 is the schematic diagram of finding time that the utility model T iron is taken out punch die.
Fig. 3 is the material returned schematic diagram that the utility model T iron is taken out punch die.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similarly element numbers represents similar element.
Please refer to Fig. 1-3, described T iron is taken out punch die and is comprised patrix 1, counterdie 2, lower bolster 3, fixed head 4, spacing collar 5, buoyance lift spring 6, fixing thimble 7, material returning sleeve 8, material returned thimble 9 and blowing nozzle 10.
The bottom centre of described patrix 1 convexes with salient point 1a.Described fixed head 4 is fixed on the upside of described lower bolster 3, and described counterdie 2 is positioned at the top of described fixed head 4 and described lower bolster 3, and described buoyance lift spring 6 is supported between described counterdie 1 and described lower bolster 3.Described spacing collar 5 is fixed on described lower bolster 3 upsides, and described spacing collar 5 tops hook the outer rim at described counterdie 2.The lower end of described fixing thimble 7 is fixed on described fixed head 4, and the upper end of described fixing thimble 7 is stretched in the centre bore of described counterdie 2.Described material returning sleeve 8 is movably set on described fixing thimble 7.Described material returned thimble 9 passes successively described lower bolster 3 and described fixed head 4 and its top and supports the bottom in described material returning sleeve 8.Described blowing nozzle 10 is connected to compressed air source, and described blowing nozzle 10 is positioned at the top of described counterdie 2.
It is as follows that the utility model T iron is taken out hole technique:
(1), provide above-mentioned T iron to take out punch die.
(2), make described counterdie 2 shift to extreme higher position, the center pillar part of T ironworker's part 11 is all put into the centre bore of described counterdie 2.When described counterdie 2 shifts to extreme higher position, described spacing collar 5 tops hook the outer rim (as shown in figure mono-) at described counterdie 2.
(3), make described patrix 1 descending, making described patrix 1 suppress T ironworker's part 11 makes counterdie sink down into extreme lower position together with T ironworker's part 11, meanwhile, utilize described salient point 1a and described fixing thimble 7 respectively the cylinder counterbore of T ironworker's part 11 and center pillar mesopore to be extruded to formation T iron finished product 12.In this step, when the descending compacting of described patrix 1 T ironworker part 11, described counterdie 2 compresses described buoyance lift spring 6 and makes its compression.When the descending compacting of described patrix 1 T ironworker part 11, described counterdie 2 departs from described spacing collar 5(as shown in Figure 2).
(4), make described patrix 1 up, described buoyance lift spring 6 pushes described counterdie 2 makes described counterdie 2 rise to extreme higher position, rise and described material returning sleeve 8 and T iron finished product 12 are together boosted with seasonal described material returned thimble 9, making T iron finished product 12 depart from the centre bore (as shown in Figure 3) of described counterdie 2.
(5), utilize described blowing nozzle 10 to blow to the T iron finished product 12 being boosted, make T iron finished product 12 leave T iron completely and take out punch die (as shown in Figure 3).Thereby reach the object of the demoulding, complete the process of whole compacting.
Owing to being provided with described fixing thimble 7, and convex with salient point 1a in the bottom centre of described patrix 1, the vertical center line of the vertical center line of described fixing thimble 7 and described salient point 1a overlaps, thereby can make cylinder counterbore moulding together with center pillar mesopore of T iron product 11, and can guarantee the concentricity of counterbore and center pillar mesopore, the concentricity of counterbore and center pillar mesopore is reached in 0.05mm; In addition, take out by mould the mode that hole replaces drilling machine boring, not only can control well counterbore internal diameter and height, make the size of counterbore more stable, and it is faster to compare drilling machine process velocity, efficiency is higher, the mach processing capacity of a large amount of minimizings, improve production capacity and shorten the production cycle (as shown in the table is the contrast of the utility model and prior art), also not producing waste material, thereby saved cost; Due to material returned thimble 9 being set, thereby can make 12 demouldings easily of T iron finished product.
In conjunction with most preferred embodiment, the utility model is described above, but the utility model is not limited to the embodiment of above announcement, and should contains the various modifications of carrying out according to essence of the present utility model, equivalent combinations.
