Abstract
The utility model discloses a kind of petal-shaped structure forging punches, drift cutting edge uses petal-shaped structure, it is made up of convex cutting edge and recessed cutting edge, convex cutting edge and recessed cutting edge are uniformly interspersed along the circumference in hole, and convex edge width is 3 5mm, and recessed cutting edge is circular arc, depth is 0.5 to 1 times of forging hole Web thickness, drift middle part is provided with groove, and depth of groove is 1 to 1.5 times of forging hole Web thickness, and cutting edge madial wall is 10 15 ° with the angle of vertical direction.The utility model has the advantages that：Reduce the pass deformation occurred during removal forging endoporus gross weight, ensure the positional precision in hole simultaneously, make gross weight substep in punch process and equably sheared along pass periphery, on the one hand the deformation force of punching can be reduced, on the other hand makes the position in hole keep stabilization not shift in punch process；Additionally, cutting edge data target of the present utility model can guarantee that fracture is smooth, burr is smaller and easy discharging.
Description
Technical field
The utility model belongs to forging field, and forging endoporus connecting rod is removed in die forging production process specifically
Drift.
Background technology
There is variously-shaped hole shape structure in the general portion in the product of the forging products such as some connecting rods, flange, wheel hub, gear,
Need the gross weight in hole to get rid of in forging process, the die forging production technology of this kind of forging products is generally comprised：Heating, blocking,
The operations such as finish-forging, trimming, punching, correction, can form certain thickness gross weight in finish-forging process hole, and punching is using drift pair
Gross weight in forging hole is got rid of, a through hole is formed, reduces later stage machining operations amount, to after the punching forgings that have for most
Whole size, in traditional punch structure general closed planar or inclined-plane, but punch process, flat punch is entered simultaneously due to one week cutting edge of drift
Row work, causes shearing force and frictional force larger, and hole can deform, dimension overproof；Although and beveled punch structure deformation phase
To relatively light, but cutting edge inclined-plane can produce side force during due to punching, and the forging higher for some required precisions can cause hole
Footpath center shifts.
Utility model content
To ensure that punching deformation is small and ensures that the center in hole does not shift, the purpose of this utility model is to provide
A kind of drift of petal-shaped structure, it is ensured that punching quality, the technical solution of the utility model is：
A kind of petal-shaped structure forging punches, drift cutting edge uses petal-shaped structure, is made up of convex cutting edge and recessed cutting edge, convex
Cutting edge and recessed cutting edge are uniformly interspersed along the circumference in hole, and convex edge width is 3-5mm, and recessed cutting edge is circular arc, and depth is forging
0.5 to 1 times of part hole Web thickness, drift middle part is provided with groove, and depth of groove is the 1 to 1.5 of forging hole Web thickness
Times, cutting edge madial wall is 10-15 ° with the angle of vertical direction.
The utility model has the advantages that：Reduce the pass deformation occurred during removal forging endoporus gross weight, while ensureing hole
Positional precision, gross weight substep is made in punch process and is equably sheared along pass periphery, on the one hand can reduce punching
Deformation force, on the other hand make in punch process hole position keep stabilization do not shift；Additionally, sword of the present utility model
Mouthful data target can guarantee that fracture is smooth, and burr is smaller and easy discharging.
Brief description of the drawings
Fig. 1 is a kind of drift schematic diagram of petal-shaped structure；
Fig. 2 is cutting edge partial schematic diagram；
In figure, 1- drifts；The convex cutting edges of 2-；The recessed cutting edges of 3-；4- grooves.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment describes the utility model in detail.
Main contents of the present utility model include：A kind of drift of petal-shaped structure；2) drift of petal-shaped structure is designed
Application method.The utility model is used for punching link during forging, reduces the hole occurred during removal forging endoporus gross weight
Deformation, while ensure hole positional precision.
As shown in figure 1, a kind of drift of petal-shaped structure of the utility model, including 1- drifts；The convex cutting edges of 2-；The recessed swords of 3-
Mouthful；4- grooves；Drift cutting edge uses petal-shaped structure, is made up of convex cutting edge 2 and recessed cutting edge 3, and convex cutting edge 2 and recessed cutting edge 3 are along hole
Circumference be uniformly interspersed, the width w=3-5mm of convex cutting edge 2, recessed cutting edge 3 be circular arc, depth h1 be forging hole Web thickness
0.5 to 1 times, drift middle part design fluted 4, the depth h of groove 4 is 1 to 1.5 times of forging hole Web thickness, cutting edge
Madial wall 5 is designed with a=10-15 ° of certain angle.
During punching forgings, drift 1 is moved to forging metapore gross weight under external force, circumferentially equally distributed convex
Cutting edge 2 is first contacted with gross weight, and local gross weight is first sheared, and gross weight is stepped into the groove 4 of drift, with drift to
Lower movement travel is increased, and recessed cutting edge 3 is gradually contacted and sheared with gross weight, when drift moves down certain stroke, recessed sword
After gross weight is all cut sky by mouth 3, punch work is completed, due to cutting edge side wall 5 and angled a=10-15 ° of vertical direction, rushed
The gross weight removed will not be stuck in groove 4, can be removed easily.
Experiment proves that, depth h1 is 0.5 times of forging hole Web thickness, and the depth h of groove 4 is forging hole Web thickness
At 1.5 times, when cutting edge side wall 5 and vertical direction angle a are less than 10 °, gross weight can be often stuck in groove 4；And work as a be more than in
At 15 °, because gross weight increased punching resistance, otch is crude, is punched poor quality；Can be unfavorable to being punched；The examination of different indexs
Test data such as table 1：
Table 1
From data above, depth h1 is 0.5 to 1 times of forging hole Web thickness, and depth of groove h is forging hole gross weight
It is best in quality when 1 to 1.5 times of thickness, a=10-15 ° of cutting edge madial wall angle.
Claims (2)
1. a kind of petal-shaped structure forging punches, it is characterised in that：Drift cutting edge uses petal-shaped structure, by convex cutting edge and recessed sword
Mouth composition, convex cutting edge and recessed cutting edge are uniformly interspersed along the circumference in hole, and recessed cutting edge is circular arc, and depth is thick forging hole gross weight
0.5 to 1 times of degree, drift middle part is provided with groove, and depth of groove is 1 to 1.5 times of forging hole Web thickness, cutting edge inner side
Wall is 10-15 ° with the angle of vertical direction.
2. petal-shaped structure forging punches according to claim 1, it is characterised in that：Convex edge width is 3-5mm.
