Abstract
The invention discloses a one-time rib-upsetting and flaring forming die for an oil inlet pipe of a gasoline engine, which is characterized by comprising a set of half dies and two sets of forming dies, wherein the two sets of forming dies are respectively a rib-upsetting die and a flaring die, and the rib-upsetting die and the flaring die are respectively positioned on the right side and the left side of the half dies; the haversian die carries out the centre gripping to the oil pipe for gasoline engine, mound muscle mould under the effect of press to haversian die direction motion is right gasoline engine carries out mound muscle shaping with the one end of advancing oil pipe, simultaneously mound muscle mould promotes the haversian die to flaring die direction motion utilizes mold core in the flaring die is right the one end of advancing oil pipe for gasoline engine carries out the reaming shaping. The invention solves the problem of twice molding of the pier ribs and the flaring and the problem of low molding efficiency, and can ensure the stability, consistency and reliability of the pier ribs and the flaring at the two ends of the oil inlet pipe.
Description
Technical Field
The invention relates to the technical field of oil inlet pipe forming for gasoline engines, in particular to a one-step rib-upsetting and flaring forming die for an oil inlet pipe for a gasoline engine.
Background
In the fuel oil distribution system, two ends of the fuel oil inlet pipe are formed twice in a conventional design, and the formed fuel oil pipe is connected with a main fuel oil pipe through a stamping part and needs a plurality of processes such as assembly, brazing, detection and the like. When the oil inlet pipe is formed, the original process is that one end of a press is formed firstly, and then the other end of the press is formed by replacing a die. However, the oil inlet pipe produced in the prior art cannot be formed by one-time blunt rib and flaring, and has high price and low production efficiency.
Disclosure of Invention
The invention aims to solve the problems of high price and low production efficiency in the prior art that ribs are formed at two ends of an oil inlet pipe for a gasoline engine through two-step process forming, and provides a forming die for one-step rib forming and flaring of the oil inlet pipe for the gasoline engine, so that the one-step rib forming and flaring forming of the oil inlet pipe are ensured.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
a kind of gasoline engine uses the oil inlet pipe once to mound the rib, flaring the shaping die, formed by one set of mould and two sets of forming dies, wherein two sets of forming dies are mound rib mould and flaring die separately, said mound rib mould and flaring die locate at said right, left both sides of mould of hafu separately; the haversian die carries out the centre gripping to the oil pipe for gasoline engine, mound muscle mould under the effect of press to haversian die direction motion is right gasoline engine carries out mound muscle shaping with the one end of advancing oil pipe, simultaneously mound muscle mould promotes the haversian die to flaring die direction motion utilizes mold core in the flaring die is right the one end of advancing oil pipe for gasoline engine carries out the reaming shaping.
In a preferred embodiment of the invention, a positioning and flaring cavity is arranged at the left side of the die cavity of the haversian die, and a pier rib cavity is arranged at the right side of the die cavity of the haversian die.
In a preferred embodiment of the invention, the cavity of the haver mould is polished.
By adopting the technical scheme, the invention solves the problem of twice molding of the pier ribs and the flaring and the problem of low molding efficiency, and can ensure the stability, consistency and reliability of the pier ribs and the flaring at the two ends of the oil inlet pipe.
Drawings
FIG. 1 is a schematic structural view of a one-time rib-upsetting and flaring forming die for an oil inlet pipe of a gasoline engine.
Detailed Description
The invention is further described below in conjunction with the appended drawings and detailed description.
Referring to fig. 1, the one-time rib-upsetting and flaring forming die for an oil inlet pipe of a gasoline engine shown in the figure is composed of a set of haversian dies 10 and two sets of forming dies, wherein the two sets of forming dies are respectively a rib-upsetting die 20 and a flaring die 30, the rib-upsetting die 20 is positioned on the right side of the haversian dies 10, and the flaring die 30 is positioned on the left side of the haversian dies 10.
The haversian die 10, the pier rib die 20 and the flaring die 30 are all made of hard alloy, and the die cavity of the haversian die 10 is polished. The left side of the die cavity of the haversian die 10 is provided with a positioning 11 and an expanding cavity 12, and the right side of the die cavity of the haversian die 10 is provided with a pier rib cavity 13.
During molding, the haver die 10 clamps an oil inlet pipe for a gasoline engine and is positioned by the positioning 11 at the left side of the die cavity of the haver die 10. The rib-upsetting die 20 moves towards the haversian die 10 under the action of the press machine, a rib-upsetting head 21 in the rib-upsetting die 20 is matched with a rib-upsetting cavity 13 on the right side of the die cavity of the haversian die 10 to perform rib-upsetting forming on one end of an oil inlet pipe for the gasoline engine, the press machine continues to pressurize simultaneously, the rib-upsetting die 20 pushes the haversian die 10 to move towards the flaring die 30, and a die core 31 in the flaring die 30 and an expanding cavity 12 on the left side of the die cavity of the haversian die 10 are matched to perform hole expanding forming on one end of the oil inlet pipe for the gasoline engine.
