Abstract
The invention discloses a novel spring die rack, relating to a punching die part, which comprises an upper die base, a lower die base, a die handle, a guide sleeve and a guide column. A base plate is arranged on the lower surface of the upper die base; a cylindrical spring is sleeved outside the guide sleeve and the guide column; the die handle is a floating die handle; a ball is arranged inside a gap which is matched with the guide sleeve and the guide column. Preferably, the upper die base and the lower die base are manufactured by using Q235 steel boards. Preferably, the guide sleeve and the guide column are manufactured by 20 steel. The novel spring die rack provided by the invention can be automatically reset when being formed by punching and has a high resetting precision. Furthermore, the novel spring die rack has a high guide precision, improves a precision of punching products and is very practical.
Description
Technical field
The present invention relates to a kind of stamping die parts, relate in particular to a kind of novel spring mould bases.
Background technology
Stamping die is a kind of industrial equipment commonly used, it can carry out processing and forming such as punching, blanking, bending and stretching, mould bases is the most frequently used parts of stamping die, existing mould bases generally comprises upper bolster, die shoe, die shank, guide pin bushing and guide pillar, die shank is installed on the forcing press, descending and the last provisional capital of upper bolster is to carry out under the drive of forcing press, and the influence of its machine of being stressed that resets is big, and reseting precision is low.Its guiding is fully by guide pin bushing and guide pillar in addition, and guiding accuracy is low, causes the low even product rejection of precision of product.
Summary of the invention
Problem at above-mentioned prior art exists the invention provides a kind of novel spring mould bases, when punch forming, can automatically reset, and the reseting precision height, guiding accuracy height of the present invention has in addition improved the precision of product, and is very practical.
Technical scheme of the present invention is: a kind of novel spring mould bases, comprise upper bolster, die shoe, die shank, guide pin bushing and guide pillar, the upper bolster lower surface is provided with backing plate, described guide pin bushing and guide pillar are socketed with helical spring outward, described die shank is the die shank that floats, and is provided with ball in the gap that guide pin bushing and guide pillar cooperate.
As preferably, described upper bolster and die shoe adopt the Q235 steel plate to make.
As preferably, described guide pin bushing and guide pillar adopt 20 steel to make.
The invention has the beneficial effects as follows: the present invention adopts unsteady die shank, and forcing press is selected the eccentric-type press of range-adjustable for use, finishes a punching press, and after forcing press was up, upper bolster resetted under the effect of helical spring, and the influence of the machine that is stressed is little, the reseting precision height.Backing plate makes things convenient for solid punch, the wearing and tearing of upper bolster in the time of can preventing punching press in addition.The ball that is provided with in the gap that guide pin bushing and guide pillar cooperate can increase guiding accuracy, thereby improves the precision of product.Upper bolster and die shoe adopt the Q235 steel plate to make, and guide pin bushing and guide pillar adopt 20 steel to make, good combination property, long service life.Very practical.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As one embodiment of the present invention, as shown in Figure 1, a kind of novel spring mould bases, comprise upper bolster 1, die shoe 2, die shank 3, guide pin bushing 4 and guide pillar 5, upper bolster 1 lower surface is provided with backing plate 8, described guide pin bushing 4 and the guide pillar 5 outer helical springs 7 that are socketed with, described die shank 3 is the die shank that floats, and is provided with ball 6 in the gap that guide pin bushing 4 and guide pillar 5 cooperate.In the present embodiment, as preferably, described upper bolster 1 and die shoe 2 adopt the Q235 steel plates to make.Described guide pin bushing 4 and guide pillar 5 adopt 20 steel to make.The forcing press that cooperates with the present invention is selected the eccentric-type press of range-adjustable for use.
