Abstract
The utility model provides a die for punching a cylindrical tube one-side square hole on punch equipment. The die comprises a cutting edge terrace die, a replaceable wedge-type concave die and a fixed protective sleeve base of a wedge-type discharging insert block, wherein the inner diameter of the cutting edge terrace die is the same to the outer diameter of the cylindrical tube to be processed, and blade width of a hole of the wedge-type concave die is 3 to 4 millimeters. A blanking cavity of a main part of the replaceable wedge-type concave die is trimmed to a square cone, and the square cone is small in the hole and big at the bottom. The fixed protective sleeve base of the wedge-type discharging insert block is used for strengthening the intensity and fixing a tube column. The inclined angle of an inserting block of the replaceable wedge-type concave die and the wedge-type discharging insert block is 4 degrees. Due to the fact that the die punches the cylindrical tube one-side square hole, the tube is even in stress and the hole is little in deformation when the terrace die blanks. The concave die can strengthen and fix an inner hole of the tube column and be dismantled rapidly, and meets requirements of fast production. When the cutting edge is worn and blunt, the die can be displaced rapidly and continues the production with no dismantlement of a whole set of the die required.

The specific embodiment
Below, with the embodiment of accompanying drawings the utility model.
According to the punch die that is used for punching press column casing pipe fitting single face square opening on punching apparatus of present embodiment by cutting edge punch 1; Can change Wedge type die 2; The Wedge type discharging is inserted to fix and is protected formation such as cover seat 3 special-purpose members such as grade.Wherein, said cutting edge punch, can change Wedge type die, the band wedge-type discharging fixing critical piece such as cover seat of protecting of inserting following characteristics are specifically arranged:
As shown in Figure 3, it shows according to the cutting edge punch 1 in the punch die of the utility model, the material C r12MoV heat treatment 54～58HRC of this punch 1.The control of punch internal diameter must be consistent with the column casing external diameter of pipe, will cause distortion otherwise the shearing force of stamping-out on tubing string is inconsistent, and the punch edge width is controlled at 0.5～0.7mm, the too sharp tipping of cutting edge, and wide aperture subsides; Because lockhole size resilience behind the stamping-out, the punch size is being set on the product size basis and the wide 0.1mm resilience surplus that respectively increases, and lockhole can satisfy the product drawing requirement fully behind the stamping-out.
Fig. 4 shows the said Wedge type die 2 that changes, and the material of this die 2 is CrWMn, heat treatment 50～55HRC.Die 2 inserts the column casing pipe orifice, inserts length and changes apart from difference with lockhole, and hole dimension has fluctuation range in the shaping column bobbin, and body diameter will change with bore.Die working portion outside diameter control is less than column casing bore 0.3～0.4mm, and strict control die square opening is to the position degree 66 ± 0.02mm of dowel hole.
Cutting edge of die partly is divided into two semicircle tapered wedges up and down; Following tapered wedges weldering one handle (length is confirmed with the column casing length of tube is corresponding); The cutting angle of tapered wedges is the best with 4 °, both can be from the slip of pinning tapered wedges when stamping-out, and it is easy again to extract out after work is accomplished.
Fig. 5 shows the partial left side view that can change Wedge type die 2; Wherein (a) illustrates separable tapered wedges 21 and blanking die cavity S wedging state before; (b) separable tapered wedges 21 and blanking die cavity S wedging state afterwards are shown; The shown direction of arrow A is the wedging direction in the course of work, and action bars 22 is arranged on the separable tapered wedges 21.As shown in the figure; The discharging of band Wedge type is inserted to fix and is protected cover seat 3; Punching press shear transfer during stamping-out is to die; Powerful punching shear can't be born die and was fractureed and that lockhole is produced is oval moment, to support holding capacity and prevented the pipe fitting distortion in order to strengthen, and the band Wedge type discharging of the design fixing cover seat 3 of protecting of inserting has played intensity and the effect of solidifying tubing string of strengthening; Moulding tubing string appearance and size also has fluctuation range, and the support zone that cooperates with it is this factor of considered also.
For making operation succinct convenient, semi arch was made into tapered wedges on the left of the Wedge type discharging was inserted, and gradient is got 4 ° of the bests.
When utilizing the punch die processing column tube single face square opening of the utility model; Each mould can be accurately consistent when guaranteeing stamping-out, lower fixed seat in the punch die of Fig. 2 and the position degree dimensional tolerance between guide pillar must and Fig. 4 in die material-dropping hole and the position degree dimensional tolerance between locating hole be consistent; Between punch and the die certain interval is arranged, gap size is got 20% of column casing pipe thickness and is the best.
In Fig. 2, cutting edge punch 1 is fixed on the cope match-plate pattern; Can change Wedge type die 2 is fixed in the lower fixed seat; The band Wedge type discharging fixing cover seat 3 of protecting of inserting is assemblied in the die ontology; Adjust between the concave, convex mould and die and the fixing peripheral clearance of protecting between the cover seat of band Wedge type unloading block, assurance uniformity, fastening then each part.
Utilize the processing method of the punch die of the utility model to be: 1. fixing said punch die is on punch press; 2. adjust the lower dead center of this punch die; 3. processing parts is packed in the die; 4. wedging two place's wedges; 5. die-cut; 6. take down two place's wedges; 7. take off part; 8. repeating step 3 to 7; So, then carry out the processing of the 2nd part.
Although described the punch die of the utility model, it is understandable that to those skilled in the art above-mentioned explanation and instance only are exemplary, and are not the scope that is used to limit the utility model through top embodiment.Under the degree of the scope that does not exceed the utility model that limits like claims, can carry out various improvement to the utility model.
