Description
The utility model relates to a kind of bending apparatus, especially a kind of automobile taper outlet pipe bending apparatus.
The outlet pipe of automobile is used to the waste gas that guides the engine interior fuel combustion to be produced, and waste gas is discharged.Have influence on dynamic efficiency and noise because exhaust is whether smooth and easy, so flow and sound that the validity of the length dimension of outlet pipe, cross section bore and circularity all can influence exhaust transmit formed reflected wave.
The increase and decrease of airflow influence power-performance curve and noise, reflected wave then influences the angle of modulator pressure regulator, and then influence oil consumption, therefore cause direct association, and direct influence is arranged because of caliber size pipe, length and the cubical content of the flow rate calculation on the outlet pipe passage and compression ratio, rotating speed, pipe, and directly have influence on performance, the size of noise, the oil consumption of motor, so the design of the caliber of outlet pipe is considerable for automobile.
The manufacture of outlet pipe is by the tapering procedure at present, bending program and make required outlet pipe, wherein the bending program is to be undertaken by bending mechanism, and general bending mechanism is at the bending of straight tube body and design, do not design at Taper Pipe, therefore in the process of carrying out the Taper Pipe bending, the situation that can cause Taper Pipe generation distortion and size deviation because of the difference of caliber, in case Taper Pipe produces distortion or size deviation, inner cubical content is changed, the smoothness of waste gas conduct route is affected, thereby have a strong impact on the performance and the oil consumption of motor, and can produce bigger noise.
The purpose of this utility model is, overcomes the shortcoming that straight tube bending mechanism is difficult to good crooked Taper Pipe, and a kind of automobile taper outlet pipe bending apparatus is provided; It not only can be used for the outlet pipe of crooked automobile, and is applicable to any other Taper Pipe.
For achieving the above object, technology of the present utility model realizes in the following manner: a kind of automobile exhaust pipe Taper Pipe bending apparatus, this bending apparatus is arranged on the board, board is provided with rotatable rotating disk, be provided with braking seat in the rotating disk periphery, be formed with groove in the braking seat, the rotating disk periphery ring is established groove, on board, be connected a location holder in addition in the rotating disk side, form groove on the holder of location, and holder place, the corresponding location of board side is provided with a stationary platen, stationary platen is provided with the interior clip-engine base of transverse movement, form in the interior clip-engine base and the corresponding groove of groove of locating on the holder, be connected a rotating platform in the positioning part of rotating disk lower end, but also be provided with the outer clip-engine base of transverse movement on the rotating platform, also form the corresponding groove of groove in the outer clip-engine base with braking seat, be characterized in: the outer groove that presss from both sides in the platform of pulling is the semicolumn groove, and the braking seat corresponding section is all the semicolumn groove, the annular groove of rotating disk periphery is the conical ring groove, and the groove that location holder and interior folder are pulled in the platform then is respectively corresponding half-conical groove, designs the bending apparatus that an inclined tube special use is provided by this.
The utility model also can be provided with indenture in the cylinder groove of above-mentioned braking seat.
Advantage of the present utility model is: a bending apparatus that designs at Taper Pipe is provided, so when carrying out bend procedure, can avoid Taper Pipe to produce the situation of distortion, and make Taper Pipe move the action of finishing bending down swimmingly, and can not produce the situation of size deviation, therefore, can make the conduct route of waste gas smooth and easy, and unlikely shadow engine performance and oil consumption can reach the purpose that reduces noise relatively.The structural feature of this device is described in detail in detail below in conjunction with accompanying drawing.
Fig. 1 is the three-dimensional appearance schematic representation of the utility model bending apparatus;
Fig. 2 is the schematic top plan view of Fig. 1;
Fig. 3, the 4th, Fig. 1 overlooks the action schematic representation.
Please referring to Fig. 1, bending apparatus 10 of the present utility model is arranged on the board 20, board 20 is to be platform-like, Yu Yiduan connects a rotating disk 11 with main shaft 21, this main shaft 21 extends to board 20 bottoms and is connected a drive mechanism 22, this drive mechanism 22 is to be connected with main shaft 21 with gear 221, and gear 221 sides are provided with a tooth bar that is engaged with 222, and this tooth bar 222 is driven by an oil hydraulic cylinder 223 and moves.
Rotating disk 11 periphery appropriate locations form braking seat 111, form semicircular cylinder groove 112 in this braking seat 111, uniform indenture 113 in the cylinder groove 112, rotating disk 11 periphery rings are established conical ring groove 114 in addition, this conical ring groove 114 in cylinder groove 112 joining place diameter minimums, and it is gradually gradually big away from cylinder groove 112 place's diameters, one location holder 23 is set on board 20 in addition, form the conical grooves 231 of semicircle arcuation in this location holder 23, the miner diameter end 232 of conical grooves 231 is connected with the cylinder groove 112 of braking seat 111, and gradually big toward board 20 direction diameters.
Please referring to Fig. 1, when the oil hydraulic cylinder 223 of driving component 22 moves, promptly drive rotating disk 11 rotations by tooth bar 222 driven gears 221 and then by main shaft 21, and during oil hydraulic cylinder 223 return motions, even rotating disk 11 counterrotatings when oil hydraulic cylinder 124,134 moves in addition, promptly promote interior clip-engine base 122, outer clip-engine base 132 respectively toward location holders 23, rotating disk 11 directions, therefore install the interoperation of each structure by this, can carry out the work of Taper Pipe bending.Be clear expression action of the present utility model, below Fig. 2,3 to Fig. 4 schematic representation described:
