Problems solved by technology

[0008] It is difficult to pull out the flange of the welding hole of the existing small oil separator, and some of the flanges that can be pulled out by the equipment for pulling out the hole and flange have different wall thicknesses, uneven heights, and even some positions around the hole. To solve the problem, the present invention provides a kind of hole pulling equipment for oil separator. Through the hole pulling machine and the drafting mold that cooperate with each other, the oil separator can be pulled out and flanged accurately and efficiently. The pulled out through hole The flanging wall thickness is uniform and the height is consistent, which is beneficial to the subsequent processing of the oil separator

Embodiment 1

[0082] Such as figure 1 As shown, a hole pulling device for an oil separator includes a hole pulling machine 100 , a drawing die 200 and a clamping die 300 . Wherein, the hole pulling machine 100 and the drafting mold 200 cooperate with each other, and are used for pulling the hole and flanging the oil separator; the clamping mold 300 is used to fix the oil separator on the drafting mold 200, so that the hole pulling machine 100 and the The drawing mold 200 can smoothly perform the hole-drawing and flanging operation on the oil separator, preventing the oil separator from shaking during the hole-drawing process, thereby affecting the hole-drawing efficiency and hole-drawing accuracy. The specific structures of the hole pulling machine 100 , the pulling die 200 and the clamping die 300 will be described in detail below.

[0083] Such as Figure 2 to Figure 5 As shown, the hole pulling machine 100 includes a frame 110 and a hole pulling device 120 installed on the frame 110 . ...

Embodiment 2

[0090] In the specific hole-drawing process of the oil separator hole-pulling device in Example 1, the hole-pulling head 210 may not be connected to the output shaft of the motor 122 quickly and accurately, thereby affecting the hole-pulling efficiency and hole-pulling accuracy. Therefore, this embodiment provides a positioning device 400 on the basis of Embodiment 1, which can accurately and quickly connect the pulling head 210 to the output shaft of the motor 122, thereby improving the hole pulling efficiency and hole pulling accuracy.

[0091] Such as figure 1 , Figure 9 and Figure 10 As shown, the positioning device 400 includes a slide table 410 and a slide seat 420 . Wherein, the slide table 410 is installed in the Y-axis direction where the fixed mold 220 is located on the upper plate 111, and is a rectangular plate-shaped structure, on which a guide groove 411 is arranged along the Y-axis direction. The slide seat 420 is a rectangular block structure, and its lowe...

Embodiment 3

[0093] This embodiment provides a method for pulling holes in an oil separator. The oil separator hole pulling equipment in Embodiment 2 is used to pull holes and flanging operations on the oil separator. The hole pulling efficiency is high, and the wall thickness of the processed flanging is uniform. , highly consistent, the specific process of the hole pulling method will be described in detail below.

[0094] 1. Head positioning

[0095] Before the hole pulling equipment starts to work, the pulling head 210 needs to be positioned at the working position of hole pulling. The specific process of the positioning operation is as follows:

[0096] Make the sliding seat 420 move along the Y-axis direction on the sliding table 410 through the guide groove 411 and the guide block 421 that cooperate with each other. When the sliding seat 420 moves to the top working position of the guiding groove 411, the sliding seat 420 stops moving and the top works The position refers to the te...

Abstract

The invention discloses an oil separator hole drawing method and a hole drawing die processing method, and belongs to the field of hole drawing. The hole drawing method comprises the following steps that a drawing head located at the working position is aligned with an output shaft of a motor while the drawing head is fixed on a positioning device; then an oil separator is placed on a fixing die,and is clamped through a clamp die, and the motor is started to enable the front end of the output shaft of the motor to be connected with the drawing head; and then the motor is driven to move so asto drive the drawing head to carry out hole drawing and flanging operations on a to-be-machined hole in the oil separator, and thus the machined flange is uniform in wall thickness and consistent in height. The hole drawing die processing method comprises the steps of shape forming and heat treatment of the drawing head and the fixing die, and the manufactured hole drawing die is accurate in shape, good in wear resistance and long in service life.

Description

technical field [0001] The invention belongs to the field of hole drawing, and more specifically relates to a hole drawing method for an oil separator and a processing method for drawing a mold. Background technique [0002] At present, when designing oil separators for air conditioners, the air inlet pipe is designed on the side of the cylinder and perpendicular to the side of the cylinder, and the positions of the air inlet pipes of different oil separators are also different. Some air inlet pipes are designed to be located in the center of the cylinder. On the line, some intake pipe designs deviate from the centerline of the barrel. In order to ensure the welding strength of the intake pipe, the welding holes are usually pulled out and flanged, and the flanging height generally reaches 2-4mm. [0003] The processing technology of hole pulling is usually punching first, and then hole pulling. The punching process is relatively simple, and can be realized by punching on a...
