Abstract
The utility model relates to a protection device of a lower die base of a numerical control turret punch press. The protection device of the lower die base of the numerical control turret punch press comprises the lower die base and is characterized in that a detachable protection assembly is arranged on the lower die base. The protection device of the lower die base of the numerical control turret punch press is arranged on the lower die base in a detachable mode and can be replaced according to the length of an upper die, and the protection assembly can be replaced at any time when damaged. Due to the arrangement of the protection assembly with a buffering function on the lower die base, direct impact of the upper die on the lower die base can be avoided, damage of the lower die base is prevented, and the service life of the lower die base is prolonged.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of NC turret punch machine die shoe protective device.
Background technology
The digital stamping mould is that punching press reaches finished product to the metal blank phase through punch (patrix) and die (counterdie), and die shoe is very important parts in die assembly.The NC turret punch machine die shoe is the Lower Half of whole secondary punch die, namely is installed on the punch die part on the capstan head work top, is counterdie and the parts that the capstan head work top contacts, and is generally plate, and it directly is fixed on capstan head work top or backing plate.During the numerical control punch die chassis design, during duty, patrix can directly impact die shoe, easily die shoe is caused to hard damage, has reduced the service life of die shoe.
The utility model content
The utility model has overcome the deficiencies in the prior art, provides a kind of and can extend die shoe service life, and the protective device that can change at any time.
For achieving the above object, the technical solution adopted in the utility model is: a kind of NC turret punch machine die shoe protective device, comprise die shoe, and it is characterized in that: described die shoe is provided with the detachable protective assembly.
In preferred embodiment of the utility model; comprise that further described protection assembly comprises upper padding plate and the lower bolster that be arranged in parallel; between described upper padding plate and lower bolster, be provided with cushion, on described upper padding plate, lower bolster and cushion, offer the through hole that is communicated with described die shoe.
In preferred embodiment of the utility model, comprise that further described upper padding plate, lower bolster and cushion are fixed on described die shoe by steady pin.
In preferred embodiment of the utility model, comprise that further described cushion is acrylonitrile-butadiene rubber.
In preferred embodiment of the utility model, comprise that further described upper padding plate, lower bolster are corrosion resistant plate.
In preferred embodiment of the utility model, comprise that further the mould district of the diameter of described through hole and described die shoe is measure-alike.
In preferred embodiment of the utility model, comprise that further described steady pin is guide blot.
In preferred embodiment of the utility model, comprise that further described upper padding plate, lower bolster and cushion are by hot composite combined.
In preferred embodiment of the utility model, the thickness that further comprises described steel plate is 0.8mm～2.0mm.
In preferred embodiment of the utility model, comprise that further described upper padding plate, lower bolster and cushion are fixed on described die shoe by four described guide blots.
The utility model has solved the defect that exists in the background technology, and NC turret punch machine die shoe protective device of the present utility model, be arranged on die shoe removably, can change according to the length of patrix, if the protection assembly is damaged, also can change at any time; By the protection assembly with cushioning effect is set on die shoe, can avoid patrix directly to impact die shoe, prevent the die shoe damage, extended the service life of die shoe.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structure cutaway view of preferred embodiment of the present utility model;
In figure: 10, die shoe, 20, patrix, 31, upper padding plate, 32, lower bolster, 33, cushion, 40, guide blot.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of NC turret punch machine die shoe protective device, comprise die shoe 10, and die shoe 10 is provided with the detachable protective assembly.Die shoe 10, when design, can directly be impacted during patrix 20 duty in factor control punching machine mold chassis, and die shoe 10 is caused to hard injury, by on die shoe 10, setting up the protection assembly, die shoe is played to buffer protection function.The height of protection assembly can be set according to the length of patrix 20.
The protection assembly comprises upper padding plate 31 and the lower bolster 32 that be arranged in parallel; between upper padding plate 31 and lower bolster 32, be provided with cushion 33; on upper padding plate 31, lower bolster 32 and cushion 33, offer the through hole (not shown) that is communicated with the mould district of die shoe 10, upper padding plate 31, lower bolster 32 and cushion 33 are fixed on die shoe 10 by steady pin.It is the corrosion resistant plate of 0.8mm～2.0mm that upper padding plate 31, lower bolster 32 can adopt thickness, the main cushioning effect that rises of cushion 33, can adopt the soft materials such as acrylonitrile-butadiene rubber, fluorubber or silicon rubber, acrylonitrile-butadiene rubber not only has excellent oil resistivity, also have ageing-resistant, abrasion performance, low ventilative and cohesiveness high, the resistance to elevated temperatures of fluorubber is the same with silicon rubber, is best in present elastomer.Upper padding plate 31 and lower bolster 32 can be combined cushion 33 by the compound mode of heat, specifically can on cushion 33 two sides, apply glue, and utilize heat gun that cushion 33 is compounded between upper padding plate 31 and lower bolster 32.The mould district of the diameter of through hole and die shoe 10 measure-alike, be beneficial to 20 pairs of metal blanks of patrix and carry out punching press.
Assembly is dismountable to be connected on die shoe 10 in order to make to protect, and upper padding plate 31, lower bolster 32 and cushion 33 can be fixed on die shoe 10 by steady pin, and steady pin can adopt guide blot 40.Specifically can on die shoe 10, open four connecting screw holes, on the position of upper padding plate 31, lower bolster 32 and cushion 33 corresponding screws, also offer the installing hole that runs through, to in four guide blot 40(figure, illustrate two, two other guide blot 40 is symmetrical arranged with these two guide blots 40) penetrate respectively installing hole and screw and fix with nut.Because cushion 33 is to have flexiblely, when patrix 20 impacted downwards, cushion 33 can produce elastic deformations, and vertical upper can being subjected to displacement uses guide blot 40 can coordinate the deformation of cushion 33 on vertical.
For better protection die shoe 10, can be on die shoe 10 sheathed die sleeve, will protect assembly to be removably disposed on die sleeve, the cutting diameter of upper padding plate 31 and lower bolster 32 and die sleeve measure-alike, avoid the direct impact die sleeve of patrix 20.
NC turret punch machine die shoe protective device of the present utility model, be arranged on die shoe removably, can change according to the length of patrix, if the protection assembly is damaged, also can change at any time; By the protection assembly with cushioning effect is set on die shoe, can avoid patrix directly to impact die shoe, prevent the die shoe damage, extended the service life of die shoe.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can, in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on specification, must determine technical scope according to the claim scope.
