[0002] Parts are the basic elements that make up a machine and can be used to assemble into individual workpieces such as machines and components. The outer shells of a series of equipment such as equipment and chassis are also assembled from several parts. There are various electrical components in the equipment or chassis. The electrical components will generate heat when working. When working continuously, the internal temperature will rise. When the temperature is too high, it will seriously affect the service life of the internal electrical components.

[0003] In order to ensure the heat dissipation effect, the existing equipment casing will open heat dissipation holes on the casing. At the same time, in order to achieve the effect of dust and rain prevention, a louver heat dissipation port will be chosen to be opened. However, the bent part of the louver heat dissipation port after stamping is fixed in material, and the projection of the bent part can at most completely overlap with the opening. When the external wind is strong, dust will still enter the body, causing dust accumulation inside, affecting the service life of the internal electrical components.

DETAILED DESCRIPTION

[0025] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0026] A processing technology for heat dissipation parts, comprising:

[0027] Step 1: placing the coil into a cutting device to form a sheet-shaped cutting plate 1;

[0028] Step two, place the cut plate 1 into the stamping equipment, fix the stamping die on the stamping equipment, and stamp the cut plate 1 so that the cut plate 1 forms louver heat dissipation outlets distributed in an array along its length direction; the louver heat dissipation outlets include ventilation slots 2 and stamped bent portions 3.

[0029] Step 3, placing the extended material into a stamping device, and stamping to form an extended piece 4 corresponding to the end surface of the bending portion 3;

[0030] Step 4: Place the extension piece 4 and the cut plate piece 1 on a welding fixture, such as Figure 1 and Figure 2 As shown, the welding fixture includes a downloading tool and a positioning module, the downloading tool includes a bottom plate 5 and a support plate 6, the positioning module includes a plurality of extrusions 7 corresponding to the heat dissipation outlets of the louver, and the extrusions 7 are movably connected in a direction perpendicular to the end surface of the bending portion 3; the cross section of the extrusion 7 is L-shaped, and one end of the extrusion 7 close to the bending portion 3 is provided with an arc surface, and contacts with the side of the bending portion 3 facing the ventilation slot 2, and the bottom of the extrusion 7 is in contact with the top surface of the cutting plate 1, and the arc is provided, and the bottom of the extrusion 7 is in contact with the top surface of the cutting plate 1, so that the positioning effect of the extrusion 7 is more stable and more accurate;

[0031] The tops of the plurality of extrusion members 7 are provided with support members 8 extending toward both sides of the lower tool, and the plurality of support members 8 are fixedly connected by connecting members 10. By setting the connecting members 10, the plurality of extrusion members 7 are connected together, and synchronous movement can be performed, making the movement of the extrusion members 7 more convenient; slide grooves 12 are provided on both sides of the bottom plate 5, and the connecting member 10 is provided with a sliding member 11 that slides with the slide groove 12. The setting of the slide groove 12 limits the movement trajectory of the connecting member 10, making the movement of the connecting member 10 and the extrusion member 7 more stable;

[0032] An elastic member 13 is provided in the slide groove 12, one end of the elastic member 13 is arranged on the inner side wall of the slide groove 12, and the other end of the elastic member 13 is arranged on one side of the sliding member 11. The elastic member 13 has elastic deformation potential energy for driving the sliding member 11 to move so that the extruding member 7 resists the extending member 4. By arranging the elastic member 13, when the extending member 4 is placed on the end face of the bending portion 3, the elasticity of the elastic member 13 is utilized to make the extruding member 7 apply an external force toward the end face of the bending portion to achieve the extrusion of the extending member 4, thereby playing a role in positioning the extending member 4, and the cross section of the extruding member 7 is L-shaped, which can support the bottom surface of the extending member 4, and because the cross section of the extending member 4 corresponds to the end face of the bending portion 3, the extending member 4 is arc-shaped, and the bending portions at both ends thereof are located on both sides of the extruding member 7 and contact with both sides of the extruding member 7, and the horizontal movement of the extending member 4 is also restricted, and the two sides of the extruding member 7 can be rounded to achieve the effect of preventing the extending member 4 from being damaged;

[0033] A support spring 14 is provided between the bottom plate 5 and the support plate 6. The support spring 14 has elastic deformation potential energy for driving the support plate 6 away from the bottom plate 5. The elasticity of the support spring 14 is used to make the finished plate close to the extrusion member 7, so that the cutting plate 1 is close to the extrusion member 7, so that the bottom of the extrusion member 7 is in contact with the top surface of the cutting plate 1, thereby ensuring the positioning effect of the positioning module; and the compression of the support spring 14 allows the support plate 6 to be away from the extrusion member 7. When the support plate 6 is away from the extrusion member 7, it is more convenient to take out the cutting plate 1; a limiting plate 9 is also fixedly connected to the top of the support plate 6 and is located on one side of the cutting plate 1, which can cooperate with the extrusion force applied by the extrusion member 7 to the extension member 4, thereby preventing the effect of displacing the cutting plate 1 by the extrusion force, further ensuring the positioning effect of the positioning mold;

[0034] After the pressing is completed, the support plate 6 is moved away from the extrusion member 7 and the support spring 14 is compressed; then the cutting plate 1 is placed on the top surface of the support plate 6 and close to the limit plate 9, and the connecting member 10 is moved. The moving method can also use a mechanical arm or a cylinder and other equipment, which saves time and effort. The extrusion member 7 is away from the limit plate 9, and the elastic member 13 is compressed until the extrusion member 7 is located on the side of the heat dissipation port of the shutter away from the limit plate 9, and the support plate 6 is released to allow the support spring 14 to reset, and the support plate 6 is close to the extrusion member 7 until the top of the cutting plate 1 contacts the bottom of the extrusion member 7. At this time, the extension member 4 is placed between the extrusion member 7 and the bending portion 3 and is located on the extrusion member 7. The connecting member 10 is released, and the elastic member 13 is reset, so that the extrusion member 7 moves toward the position close to the limit plate 9, thereby squeezing the extension member 4. The extension piece 4 is pressed to complete the positioning of the extension piece 4, thereby achieving the effect of positioning and fixing the extension piece 4 and the cutting plate 1 by using the welding fixture, and then the extension piece 4 is welded to the end face of the bending portion 3 by welding. In order to ensure the welding stability, the two ends of the extension piece 4 can also be welded to the cutting plate 1; after the welding is completed, the connecting piece 10 is moved and the supporting plate 6 is pressed, so that the welded cutting plate 1 can be taken out more conveniently. In order to further ensure the welding effect, the back of the extension piece 4 can also be reinforced by electric welding; the setting of the welding fixture makes the positioning of the cutting plate 1 and the extension piece 4 more stable and prevents shaking, making the welding more accurate and more stable, and ensuring the quality of the product; the projection of the welded extension piece 4 is located outside the ventilation slot 2, thereby further ensuring the dustproof effect of the overall louver heat dissipation hole and preventing dust from passing through the ventilation slot 2;

[0035] Step 5: Place the welded cut plate 1 into a magnetic grinder to polish and grind the surface of the cut plate 1. Use the magnetic grinder to make the surface grind smoother, thereby preventing burrs from being generated and affecting the subsequent assembly effect. After grinding, package and store it to complete the processing of the entire part.

[0036] Step six, the equipment assembled by using the processed parts, due to the setting of the louver heat dissipation holes and the extension part 4, can effectively prevent dust from entering the body, causing dust accumulation in the equipment and affecting the service life of the internal electrical components, thereby ensuring the service life of the entire equipment.
