Description

Technical Field

[0001] The present invention belongs to the technical field of processing the air guiding cover of an air cooler housing, and particularly relates to a processing method for the air guiding cover of an air cooler housing. Background Art

[0002] An air cooler mainly drives a fan impeller by a motor to form an air flow, and guides external air through an air guiding cover to ensure that the air flow evenly passes through a heat dissipation mechanism, thereby improving the heat exchange efficiency.

[0003] In the prior art, if the heat exchange efficiency requirement of the air cooler is high enough, a larger motor needs to be installed, and a special motor mounting structural member is used to carry the motor and its components, and it cannot be directly mounted on the air guiding cover, and an avoidance structure for the motor mounting structural member needs to be provided on the air guiding cover.

[0004] Currently, when processing the air guiding cover, the spinning process is often used to plastically deform one end of the cylinder to form a flange part by flanging. However, in order to set the avoidance structure, an opening is made at the end of the cylinder where the flange part is formed. When the cylinder with the opening is spin-processed, the opening position of the cylinder cannot be stretched, which easily causes deformation in an unpredictable direction; at the same time, during the spinning process, the cylinder rotates at a high speed, and strong vibration will occur when the roller of the spinning equipment acts on the cylinder again after passing through the opening position. Summary of the Invention

[0005] The present invention provides a processing method for the air guiding cover of an air cooler housing to overcome the defects of the prior art, which can improve the processing quality of the air guiding cover with an avoidance structure.

[0006] The purpose of the present invention is achieved by the following technical solutions:

[0007] A processing method for the air guiding cover of an air cooler housing includes the following steps:

[0008] Prepare a flat plate, and sequentially pre-divide the flat plate in the width direction into a connected body part and a flange part, and respectively pre-define a first opening part and a second opening part on the body part and the flange part, wherein the connection line between the first opening part and the flange part is the same as the connection line between the second opening part and the body part;

[0009] Cut a first opening part on the body part that is only integrally connected to the flange part;

[0010] Roll the flat plate into a cylindrical shape along the length direction, and then integrally connect the two ends of the flat plate to form a cylindrical part;

[0011] Fix one end of the cylindrical part, and then perform spinning processing to flange the other end of the cylindrical part to form a flange part;

[0012] A second cutout portion on the blanking flange portion is provided so that the first cutout portion and the second cutout portion are respectively detached from the main body portion and the flange portion together, thereby forming a notch on the cylindrical member.

[0013] The beneficial effects of adopting the above technical solution are as follows: After the first cutout portion is cut and formed on the main body portion, the first cutout portion is still integrally connected to the flange portion, that is, the first cutout portion will not be detached from the flat member or the cylindrical member. The side of the first cutout portion away from the flange portion is still in contact with the main body portion. And when the other end of the cylindrical member is flanged to form the flange portion by spinning, no second cutout portion is formed on the flange portion, that is, the spinning process is a uniform deformation process, and the roller of the spinning equipment continuously acts on the flange portion, and no strong vibration will be generated due to the intermittent action on the flange portion. Therefore, the processing method of the air-cooled cooler housing air guide cover can improve the processing quality of the air guide cover with an avoidance structure.

[0014] Further, preparing the flat member includes:

[0015] Cutting a metal flat plate to prepare the flat member.

[0016] Further, the connection line between the first cutout portion and the flange portion and the connection line between the second cutout portion and the main body portion being the same includes:

[0017] The connection line between the first cutout portion and the flange portion and the connection line between the second cutout portion and the main body portion are both the boundary line between the first cutout portion and the second cutout portion.

[0018] Further, pre-determining the first cutout portion and the second cutout portion on the main body portion and the flange portion respectively includes:

[0019] Pre-determining a plurality of first cutout portions and a plurality of second cutout portions on the main body portion and the flange portion respectively, wherein the plurality of first cutout portions are respectively connected to the plurality of second cutout portions.

[0020] Further, cutting the first cutout portion formed only integrally connected to the flange portion on the main body portion includes:

[0021] Cutting a plurality of first cutout portions formed only integrally connected to the flange portion on the main body portion.

[0022] Further, blanking the second cutout portion on the flange portion so that the first cutout portion and the second cutout portion are respectively detached from the main body portion and the flange portion together to form a notch on the cylindrical member includes:

[0023] Blanking a plurality of second cutout portions on the flange portion to form a plurality of notches on the cylindrical member.

[0024] Further, the processing method of the air-cooled cooler housing air guide cover further includes the following steps:

[0026] Further, integrally connecting both ends of the flat plate member includes:

[0027] Welding, clamping connection or seaming of both ends of the flat plate member.

[0028] Further, fixing one end of the cylindrical member includes:

[0029] Using the expansion mechanism of the spinning equipment to expand and fix the main body part.

[0030] Further, the spinning process to form a flange portion by flanging the other end of the cylindrical member includes:

[0031] Using the roller of the spinning equipment to flange the other end of the cylindrical member to form a flange portion.

[0032] The beneficial effects of the present invention are as follows:

[0033] After the first cutout portion is formed by cutting on the main body part, the first cutout portion is still integrally connected to the flange portion, that is, the first cutout portion will not break away from the flat plate member or the cylindrical member, the side of the first cutout portion away from the flange portion is still in contact with the main body part, and when the flange portion is formed by flanging the other end of the cylindrical member using the spinning process, no second cutout portion is formed on the flange portion, that is, the spinning process is a uniform deformation process, and the roller of the spinning equipment continuously acts on the flange portion without generating strong vibration due to intermittent action on the flange portion; therefore, the processing method of the air-cooled cooler housing air guide cover can improve the processing quality of the air guide cover with an avoidance structure.

[0045] The present invention will be further described below in conjunction with the drawings.

[0046] The present invention provides a processing method for an air guiding cover of an air cooler housing, as Figure 1-7 shown, including the following steps:

[0047] Prepare a flat plate, and sequentially pre-divide the flat plate along the width direction into a connected body part 1 and a flange part 2, and respectively pre-define a first cutout part 3 and a second cutout part on the body part 1 and the flange part 2, wherein the connecting line of the first cutout part 3 and the flange part 2 is the same as the connecting line of the second cutout part and the body part 1;

[0048] Use a cutting device to cut a first cutout part 3 on the body part 1 that is only integrally connected to the flange part 2;

[0049] Roll the flat plate into a cylindrical shape along the length direction, and then integrally connect the two ends of the flat plate to form a cylindrical part;

[0050] Fix one end of the cylindrical part, and then perform spinning processing to flang the other end of the cylindrical part to form a flange part 2;

[0051] Use a punching device to punch a number of mounting holes 4 in the flange part 2;

[0052] Use a punching device to punch the second cutout part on the flange part 2, so that the first cutout part 3 and the second cutout part are respectively separated from the body part 1 and the flange part 2 together, so as to form a notch 5 on the cylindrical part, thereby forming an avoidance structure on the air guiding cover.

[0053] It can be understood that after the first cut-out portion 3 is formed by cutting on the main body portion 1, the first cut-out portion 3 is still integrally connected to the flange portion 2, that is, the first cut-out portion 3 does not detach from the flat plate or the cylindrical member. The side of the first cut-out portion 3 away from the flange portion 2 is still in contact with the main body portion 1. When the other end of the cylindrical member is flanged to form the flange portion 2 by spinning, no second cut-out portion is formed on the flange portion 2. That is, the spinning process is a uniform deformation process, and the roller of the spinning equipment continuously acts on the flange portion 2 without generating strong vibrations due to intermittent action on the flange portion 2. After the flanging of the flange portion 2 is completed, the first cut-out portion 3 on this flat end of the flange portion 2 is removed, so that the first cut-out portion 3 is separated from the cylindrical member along with the second cut-out portion to form an air guide cover with an avoidance structure. Therefore, the processing method of the air guide cover of the air cooler housing can improve the processing quality of the air guide cover with an avoidance structure and ensure the flatness of the processed air guide cover product.

[0054] In addition, compared with the processing method of separately processing the flange and the cylinder and then welding them to form the air guide cover, the processing method of the air guide cover of the air cooler housing uses spinning, which has a lower cost and higher processing efficiency.

[0055] It should be noted that cutting the first cut-out portion 3 that is only integrally connected to the flange portion 2 on the main body portion 1 can release the integral connection relationship between the first cut-out portion 3 and the main body portion 1 while retaining the surface contact relationship between the first cut-out portion 3 and the main body portion 1; punching the second cut-out portion on the flange portion 2 can release the integral connection relationship between the second cut-out portion and the flange portion 2, and the first cut-out portion 3 connected thereto also releases the integral connection relationship with the main body portion 1. Therefore, the first cut-out portion 3 and the second cut-out portion are separated from the cylindrical member together to form an avoidance structure on the air guide cover.

[0056] It should be noted that before the flat plate is rolled into a cylinder, mounting holes 4 can also be punched on the main body portion 1.

[0057] In one embodiment, preparing the flat plate includes:

[0058] Using a metal flat plate as the processing material and cutting the metal flat plate with a cutting device to prepare the flat plate.

[0059] In one embodiment, the connecting line between the first cut-out portion 3 and the flange portion 2 and the connecting line between the second cut-out portion and the main body portion 1 being the same includes:

[0061] In one embodiment, pre-determining the first cut-out portion 3 and the second cut-out portion on the main body portion 1 and the flange portion 2 respectively includes:

[0064] Cutting a number of first cut-out portions 3 formed on the body portion 1 and integrally connected only to the flange portion 2.

[0065] In one embodiment, blanking the second cut-out portions on the flange portion 2 so that the first cut-out portions 3 and the second cut-out portions are respectively detached from the body portion 1 and the flange portion 2 together to form a notch 5 on the cylindrical part includes:

[0066] Blanking a number of second cut-out portions on the flange portion 2 to form a number of notches 5 on the cylindrical part.

[0067] In one embodiment, integrally connecting the two ends of the flat part includes:

[0068] Welding, clamping connection or seaming the two ends of the flat part.

[0069] It should be noted that preferably, the two ends of the flat part are welded.

[0070] In one embodiment, fixing one end of the cylindrical part includes:
