Description
Technical Field
The invention belongs to the field of hole drawing, and particularly relates to a hole drawing method of an oil separator and a processing method of a drawing die of the oil separator.
Background
When present idle call oil separator product design, can be with the intake pipe design in barrel side and perpendicular to barrel side, and the intake pipe position of different oil separators also is different, and some intake pipe designs are located the central line of barrel, and some intake pipe designs can deviate from the barrel central line. In order to ensure the welding strength of the air inlet pipe, hole drawing and flanging are generally carried out on a welding hole, and the height of the flanging generally reaches 2-4 mm.
The hole drawing process usually comprises punching and then drawing. The punching processing is relatively simple and can be realized by punching on a punch press, but the hole-drawing processing needs to turn out a welding matching surface with a certain height from the inside of the cylinder body at the position of the welding hole, and the operation is relatively troublesome and complicated. For a large-sized oil separator (the diameter is more than or equal to 76mm), and the welding hole is designed on the central line, hole drawing can be realized by adopting punch machining generally because the inside of the oil separator has enough space for placing a die into a cylinder body. However, for small-sized oil separators (diameter < 76mm), because the internal space is small, the die can not be put into the cylinder body for processing, even if some small-sized oil separators can be put into the die for hole drawing processing, the hidden troubles of uneven flanging wall thickness, insufficient strength and the like of the processed welding holes can exist, and the problem is more prominent particularly for small-sized oil separators with some welding holes designed as eccentric holes.

This draw hole machine is through drawing out the hole spare and passing the through-hole after, the hole spare is pulled out in the control again and is rotated and extract from the through-hole and pull out the hole turn-ups, because the top of pulling out the hole spare need stretch into in the through-hole, so its concrete process of pulling out the hole can only be following two kinds: (1) the diameter of the top end of the hole pulling piece is equal to or smaller than the diameter of the through hole, after the hole pulling piece stretches into the through hole, the hole pulling piece can partially displace in the rotating process of pulling out, so that hole pulling operation is carried out on the through hole, otherwise, the hole pulling piece cannot be contacted with four sides of the through hole, however, certain mutual stress can be carried out on the hole pulling piece and the periphery of the through hole in the hole pulling process, the hole pulling can cause the position of the hole pulling piece in the hole pulling process to have errors due to hole pulling in the mode, the flanging wall thickness of the pulled out hole is different, even the situation that the part of the periphery of the through hole is not flanged is generated, and particularly, the problem is more easily generated on the hole pulling flanging of the eccentric; (2) to pull out the hole again to the through-hole in colluding the insertion through-hole, thereby this kind of hole-pulling mode need not carry out the displacement to pulling out the hole piece and touch through-hole lateral wall all around, but when it colluded the insertion through-hole, it needs certain inclination to pull out the hole piece, thereby it need pull out the turn-ups of through-hole wall thickness and the highly even of the turn-ups of through-hole of guaranteeing to pull out in the centre of a circle of hole piece perpendicular to through-hole when pulling out the hole, consequently pull out the hole piece collude the angle that needs the adjustment to pull out the hole piece after the insertion through-hole and the position pull out the hole turn-ups to the through-hole, waste time and energy and the transform of angle and position.
Also, for example, the Chinese patent application number is: CN201110068280.6, published date: patent literature of 2011 9/14 discloses an automatic hole pulling shaping machine, which comprises a workbench, a feeding mechanism, a hole pulling mechanism and a controller, wherein the hole pulling mechanism comprises a hole pulling outer sleeve, a hole pulling rod, a cutter, a hole pulling cylinder and a clamping die, a pipe fitting is sleeved outside the hole pulling outer sleeve, the hole pulling rod is arranged in the hole pulling outer sleeve, an opening for the cutter to advance and retreat is arranged on the hole pulling outer sleeve, and the cutter can slide along a wedge platform of the hole pulling rod, and is characterized in that: the fixture is controlled by the servo motor to slide on the pipe drawing hole outer sleeve, and the fixture is connected with one end of the pipe; and a transmission mechanism is arranged below the workbench and can move the workbench to the shaping mechanism from the feeding mechanism. This scheme is through mutually supporting of cutter and inclined plane wedge of bottom inclined plane that has, make the cutter can be by interior and pull out the hole operation to the through-hole on the pipe wall outwards, however, the cutter is the hole operation of pulling out of up-and-down motion under the effect of the wedge of back and forth motion, the wedge is swing joint with the cutter contact surface, the transmission of the two power has error in the actual working process, when leading to the cutter upper end to pull out the hole to the through-hole, the atress is not even all around of through-hole, the through-hole turn-ups of pulling out can appear the wall thickness differ, the uneven circumstances such as height, thereby influence the processing of subsequent process.
