Abstract
A method and apparatus for shaping a raw tube (40) into a formed part. The part can be configured within a die assembly including a hydroforming die structure (12, 14) and a pair of tube-engaging punches (81). The punches are inserted into the ends of the raw tube to shape the ends into the desired configuration. The middle portion of the raw tube is shaped into the desired configuration by hydroforming. Thus, the method and apparatus can shape the raw tube along its entire length, leaving no remnants of the raw tube that must be trimmed away.
Claims (7)

a pair of tube-end engaging structures 81 disposed at opposite ends of said die cavity 52 and constructed and arranged to engage opposite ends of said tubular blank 40, said tube-end engaging structures 81 being constructed and arranged to seal said opposite ends of said tubular blank 40 and to pressurize hydroforming fluid within said tubular blank 40 for expanding said tubular blank 40 into conformity with said interior surfaces of said die cavity 52, a first of said tube-end engaging structures 81 having an outer cross-sectional configuration corresponding to said desired cross section at said one end of said part, said first of said tube-end engaging structures 81 being movable into forced engagement with one end of said tubular blank 40 to conform said one end of said tubular blank 40 to said outer cross-sectional configuration of said first of said tube-engaging structures 81 and hence said predetermined cross section at said one end of said part.
a pair of tube-end engaging structures 81 disposed at opposite ends of said die cavity 52 and constructed and arranged to engage opposite ends of said tubular blank 40, said tube-end engaging structures 81 being constructed and arranged to seal said opposite ends of said tubular blank 40 and to pressurize hydroforming fluid within said tubular blank 40 for expanding said tubular blank 40 into conformity with said interior surfaces of said die cavity 52, a first of said tube-end engaging structures 81 having an outer cross-sectional configuration corresponding to said desired cross section at said one end of said part, said first of said tube-end engaging structures 81 being movable into forced engagement with one end of said tubular blank 40 to conform said one end of said tubular blank 40 to said outer cross-sectional configuration of said first of said tube-engaging structures 81 and hence said predetermined cross section at said one end of said part.
2. A hydroforming die assembly 10 according to claim 1, wherein said first tube-end engaging structure 81 has an exterior surface including a beveled portion 82 which is partially inserted into said one end of said tubular blank 40, said first tube-end engaging structure 81 being moved further into said one end of said tubular blank 40 so as to cause inner surface portions of said one end of said tubular blank 40 to slide in forced relation along said beveled portion 82 and cause said one end of said tubular blank 40 to be deformed i) over said first tube-end engaging structure 81 and ii) into conformity with said exterior surface of said first tube-end engaging structure 81, and wherein one end of said die cavity 52 receives said first tube-engaging structure 81, said interior surfaces of said die cavity 52 at said one end of said die cavity 52 having a configuration conforming to an exterior surface configuration of said part at said one end of said part.
3. A method of producing a hydroformed part using a hydroforming die assembly for hydroforming a part from a tubular blank 40, the part having a desired configuration different from a configuration of the blank and including a desired crass section at one end of the part, the die assembly 10 including a die structure having interior surfaces defining a die cavity 52, the die cavity 52 having a cross sectional configuration conforming to the desired cross section of the part, the method comprising the steps of:
providing and a pair of tube-end engaging structures 81 disposed at opposite ends of the die cavity 52 and constructed and arranged to engage opposite ends of the tubular blank 40, the tube-end engaging structures 81 being constructed and arranged to seal the opposite ends of the tubular blank 40 and to pressurize hydroforming fluid within the tubular blank 40 for expanding the tubular blank 40 into conformity with the interior surfaces of the die cavity 52, a first of the tube-end engaging structures 81 having an outer cross-sectional configuration corresponding to the desired cross section at one end of the part;
moving the first of the tube-engaging structures 81 into forced engagement with one end of the tubular blank 40 to conform the one end of said tubular blank 40 to the outer cross-sectional configuration of the first of the tube-engaging structures 81 and hence the predetermined cross section at the one end of the part; and applying pressure within the tubular blank 40 to form the tubular blank 40 in to the desired configuration of the part.
providing and a pair of tube-end engaging structures 81 disposed at opposite ends of the die cavity 52 and constructed and arranged to engage opposite ends of the tubular blank 40, the tube-end engaging structures 81 being constructed and arranged to seal the opposite ends of the tubular blank 40 and to pressurize hydroforming fluid within the tubular blank 40 for expanding the tubular blank 40 into conformity with the interior surfaces of the die cavity 52, a first of the tube-end engaging structures 81 having an outer cross-sectional configuration corresponding to the desired cross section at one end of the part;
moving the first of the tube-engaging structures 81 into forced engagement with one end of the tubular blank 40 to conform the one end of said tubular blank 40 to the outer cross-sectional configuration of the first of the tube-engaging structures 81 and hence the predetermined cross section at the one end of the part; and applying pressure within the tubular blank 40 to form the tubular blank 40 in to the desired configuration of the part.
4. A method according to claim 3, further comprising the step of:
incorporating the part into a product without cutting off the one end of the part formed by the forced engagement of the first of the tube-engaging structures 81.
incorporating the part into a product without cutting off the one end of the part formed by the forced engagement of the first of the tube-engaging structures 81.
5. A assembly according to claim 1, wherein a first of said tube-engaging structures 81 has a forward end 33 and a lateral shoulder 88 protruding from a multifaceted portion 84 such that the first of said tube engaging structures 81 can be inserted into said tubular blank 40 continuously from the forward end 33 of said tube-engaging structure to said lateral shoulder 88 along said multifaceted portion 84 until said lateral shoulder 88 abuts said tube-engaging structure 81 and halts further insertion of said first of said tube-engaging structures 81 relative to said tubular blank 40.
6. A method according to claim 3, wherein the moving of the first of the tube-engaging structures 81 includes inserting the first of the tube-engaging structures 81 into the tubular blank 40 continuously from a forward end 33 of the first of the tube-engaging structures 81, along a multifaceted portion 84 of the first of the tube-engaging structures 81, and to a lateral shoulder 88 of the first of the tube-engaging structures 81 that protrudes from the multifaceted portion 84, until the lateral shoulder 88 abuts the end of tubular blank 40 and halts further insertion of the tube-engaging structure 81 relative to the tubular blank 40.
