[0001] The invention relates to the technical field of copper water jackets, and in particular to a partition wall type copper water jacket and a forming process thereof. Background Art

[0002] The difference between the partition wall water jacket and the ordinary water-cooled water jacket is that both sides of the partition wall water jacket are corroded and strongly washed by the high-temperature melt, but the thermal conductivity of the existing partition wall water jacket is still not good enough.

[0003] In addition, after casting the partition wall water jacket blank, it is necessary to polish the surface of the partition wall water jacket blank carefully with a hand-held polishing tool while wearing a protective mask and earmuffs. Since the volume and surface area of ​​the partition wall water jacket are relatively large, the labor intensity of the polishing workers is high, the polishing efficiency is slow, and the polishing effect is not good. Summary of the invention

[0004] The object of the present invention is to provide a partition wall type copper water jacket and a forming process thereof, so as to solve the above-mentioned defects caused by the prior art.

[0005] A partition wall copper water jacket comprises a copper substrate and a copper tube. A plurality of heat conducting strips are evenly distributed on the left and right sides of the copper substrate, and the copper substrate and all the heat conducting strips are an integral casting. A plurality of copper tubes are evenly distributed inside the copper substrate.

[0006] Preferably, the forming process of the partition wall type copper water jacket comprises the following steps:

[0007] S1: Mold preparation: The interior of the mold includes a molding cavity for molding the copper matrix and all the heat-conducting strips, and a number of copper tubes are pre-placed in the molding cavity;

[0011] S5: Cleaning: The copper water jacket blank of the partition wall is hoisted by the gantry crane, and then the molding sand attached to the surface of the copper substrate is washed away by a water spray gun, and then the gate and riser are removed by a cutting tool, and then a processing equipment is used to process a number of heat conducting strips on both sides of the copper substrate, and then the surface of the copper substrate and the heat conducting strips is automatically polished by a polishing mechanism;

[0012] S6: Inspection: including ball-pass inspection, air-tightness inspection, internal defect inspection, appearance defect inspection and mechanical property inspection. After passing all the inspections, the partition wall copper water jacket parts are obtained.

[0013] Preferably, the grinding mechanism comprises a rectangular mounting frame, a pair of C-shaped mounting frames are symmetrically distributed inside the mounting frame, a pair of mounting columns are connected in parallel between the two ends of the mounting frame, and a number of mounting plates are slidably connected to the pair of mounting columns, and a pair of compression springs are connected between two adjacent mounting plates, and a motor is centrally mounted on each mounting plate, the motor is horizontally arranged inwardly and a grinding block is keyed at its output end, a U-shaped fixing plate is centrally mounted on the mounting frame, and a pair of cylinder 1s are symmetrically mounted on the front and rear sides of the fixing plate, the cylinder 1 is horizontally arranged inwardly and a connecting plate is connected to the end of its piston rod, a pair of hinged strips are hinged on the connecting plate, the other end of the upper hinged strip is hinged to the topmost mounting plate on the same side, and the other end of the lower hinged strip is hinged to the bottommost mounting plate on the same side, and a pair of cylinder 2s are symmetrically connected to the left and right sides of the mounting frame, the cylinder 2 is horizontally arranged inwardly and the end of its piston rod is connected to the mounting frame on the same side.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

A plurality of copper tubes 102 are evenly distributed inside the copper base 101. The two ends of the copper tube 12 are connected to the water inlet pipe and the drain pipe respectively. When cold water flows through the inside of the copper tube 102, the heat of the copper base 11 and the heat conducting strips 1011 can be taken away. The heat conducting performance is excellent, thereby reducing the working temperature of the partition wall water jacket 10.

[0030] In this embodiment, the forming process of the partition wall type copper water jacket includes the following steps:

[0031] S1: mold preparation: the interior of the mold includes a molding cavity for molding the copper substrate 101 and all the heat-conducting strips 1011, and a plurality of copper tubes 102 are pre-placed in the molding cavity;

[0032] S2: Melting: Put the copper material into the furnace and heat it to a molten state, and use a stirring tool to stir the molten copper liquid evenly;

[0033] S3: Casting: slowly pour the molten copper into the mold and fill the molding cavity of the mold with the copper. At the same time, the gas in the molding cavity is discharged through the riser and the copper liquid is added to the molding cavity.

[0034] S4: Cooling: placing the mold after casting in the air for natural cooling, and forming a partition wall copper water jacket 10 blank in the molding cavity of the mold;

[0035] S5: Cleaning: hoist the partition wall copper water jacket 10 blank by the gantry crane, then use a water gun to wash away the molding sand attached to the surface of the copper substrate 101, then use a cutting tool to remove the gate and the riser, then use a processing device to process a plurality of heat conducting strips 1011 on both sides of the copper substrate 101, and then use a polishing mechanism 20 to automatically polish the surfaces of the copper substrate 101 and the heat conducting strips 1011;

[0036] S6: Inspection: including ball-pass inspection, air-tightness inspection, internal defect inspection, appearance defect inspection and mechanical property inspection. After passing all inspections, 10 copper water jacket parts of partition wall are obtained.

[0037] In this embodiment, the grinding mechanism 20 includes a rectangular mounting frame 201, a pair of C-shaped mounting frames 204 are symmetrically distributed inside the mounting frame 201, a pair of mounting posts 205 are parallelly connected between the two ends of the mounting frame 204, and a plurality of mounting plates 206 are slidably connected to the mounting posts 205, and a pair of compression springs 207 are connected between two adjacent mounting plates 206, and a motor 208 is centrally installed on each mounting plate 206, the motor 208 is horizontally arranged inwardly and a grinding block 209 is keyed to its output end, and a U-shaped fixed spring 207 is centrally installed on the mounting frame 204. A fixed plate 210 is provided, and a pair of cylinders 1 211 are symmetrically installed on the front and rear sides of the fixed plate 210, the cylinder 1 211 is horizontally arranged inwardly and is connected to a connecting plate 212 at the end of its piston rod, a pair of hinged bars 213 are hinged on the connecting plate 212, the other end of the upper hinged bar 213 is hinged to the topmost mounting plate 206 on the same side, and the other end of the lower hinged bar 213 is hinged to the bottommost mounting plate 206 on the same side, and a pair of cylinders 2 214 are symmetrically connected to the left and right sides of the mounting frame 201, the cylinders 214 are horizontally arranged inwardly and the ends of their piston rods are connected to the mounting frame 204 on the same side.

[0038] In this embodiment, a pair of handles 202 are symmetrically mounted on the left and right sides of the mounting frame 201. With the help of the pair of handles 202, the entire grinding mechanism 20 can be easily lifted.

[0039] In this embodiment, a group of universal ball wheels 203 are installed on both the upper and lower sides of the installation frame 201, and each group is provided with a plurality of universal ball wheels 203, which are correspondingly distributed on the inner wall of the installation frame 201. When the grinding mechanism 20 moves along the partition wall water jacket 10, the friction resistance and wear between the installation frame 201 and the copper substrate 101 can be reduced by means of these universal ball wheels 203.

[0040] In this embodiment, a pair of guide posts 215 are symmetrically mounted on the side of the mounting frame 204, and the guide posts 215 are slidably connected to the mounting frame 201 through guide sleeves 216. With these guide posts 215 and guide sleeves 216, the piston rod of the second cylinder 214 can be prevented from bending due to uneven force.

[0041] The working principle of this grinding mechanism 20 includes the following operations:

[0042] When the partition wall water-permeable jacket 10 is hoisted horizontally, the mounting frame 201 in the polishing mechanism 20 is sleeved on the copper base 101 in the partition wall water-permeable jacket 10 .

[0043] When it is necessary to polish the section of the copper substrate 101 including the thermal conductive strip 1011, the piston rod of the cylinder 1 211 is extended and drives the top and bottom two mounting plates 206 away from each other, and the remaining mounting plates 206 are evenly dispersed under the action of the corresponding compression springs 207, and then the piston rod of the cylinder 2 214 is extended and drives the dispersed grinding blocks 209 to contact the left and right sides of the copper substrate 101, and then the corresponding motor 208 is activated to drive the corresponding grinding blocks 209 to rotate. When the grinding mechanism 20 moves slowly along the section, the left and right sides of the copper substrate 101 and the upper and lower sides of the thermal conductive strip 1011 in the section can be automatically polished.

[0044] When it is necessary to polish the section of the copper substrate 101 that does not contain the heat conductive strip 1011, the piston rod of the cylinder 1 211 contracts and drives the top and bottom two mounting plates 206 to approach each other, and all the mounting plates 206 are centered and close together, and then the piston rod of the cylinder 2 214 extends and drives the gathered grinding blocks 209 to contact the left and right sides of the copper substrate 101, and then the corresponding motor 208 is activated to drive the corresponding grinding blocks 209 to rotate, and when the grinding mechanism 20 slowly moves along the section, the left and right sides of the copper substrate 101 in the section can be automatically polished. Similarly, it can be known that the process of grinding the side of the heat conductive strip 1011 is similar to this.

[0045] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
