[0002] A cooler is a heat dissipation device that uses water or gas as a coolant. The pump body is an important component that absorbs the coolant and discharges the heat medium. It is a component that requires very high tightness and is generally manufactured through a casting process.

[0003] The pump body of the cooler is generally made of cast iron or cast steel to avoid corrosion and cracking. There are also pump bodies cast with aluminum alloy materials, but the higher density of cast iron or cast steel makes the pump body heavier, and the corrosion resistance and wear resistance are worse than cast aluminum. Pores and sand holes will form inside the cast aluminum, thereby reducing the impact resistance and fatigue resistance, and the surface quality is low. Therefore, it is necessary to design a forming process and forming device for the aluminum alloy pump body to improve the mechanical properties and surface quality of the product.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1:

[0037] like Figure 1As shown, the present invention provides a method for forging a precision forming valve cooler pump body, comprising the steps of:

[0038] S100, adding the aluminum alloy bar to be forged into a heating furnace for heating;

[0039] S200, placing the heated aluminum alloy bar into an upsetting die for forging to form an upsetting forging;

[0040] S300, placing the obtained upset forging into a forging die and forging to obtain an aluminum alloy pump body.

[0041] The method also includes the following steps: sequentially performing trimming, heat treatment, pickling and shot blasting on the aluminum alloy pump body to obtain the target product.

[0042] Traditionally, when using aluminum alloy to manufacture pump bodies through casting process, most casting processes now adopt casting or die casting to manufacture this product. These two methods are to heat the aluminum alloy to a molten state and then add it to the casting cavity or sand mold.

[0043] Before the metal solidifies, the gas inside the casting cavity or sand mold cannot be removed in time, resulting in the formation of pores, which causes the pump body surface to oxidize, reducing the effective bearing area of ​​the surface, and reducing the impact resistance and fatigue resistance of the casting, and gradually reducing the density, resulting in leakage and scrapping.

[0044] Through the process demonstrated by the present invention, the aluminum alloy bar is heated and then forged in an upsetting die and a forging die in sequence. The forging process avoids the occurrence of air holes inside the pump body, thereby improving the mechanical properties and surface quality of the pump body.

[0045] Example 2:

[0046] like Figure 1 and Figure 2 As shown, the present invention provides a forming device for a method for forging a precision forming valve cooler pump body, comprising:

[0047] The upsetting die 1 has a plurality of upsetting cavities 2, and the upsetting cavities 2 are used to simultaneously forge a plurality of heated aluminum alloy bars to form upsetting forgings.

[0048] The forging die 3 has a plurality of forging cavities 4 , which are used to simultaneously forge a plurality of upsetting forgings to form an aluminum alloy pump body. The number of the forging cavities 4 is the same as the number of the upsetting cavities 2 .

[0049] The material moving device 5 has an upsetting bearing part 6 and a forging bearing part 7. The upsetting bearing part 6 and the forging bearing part 7 are connected by a rotating mechanism 8. The lower die of the upsetting die 1 is fixed on the upsetting bearing part 6, and the lower die of the forging die 3 is fixed on the forging bearing part 7.

[0050] The upsetting bearing part 6 and the forging bearing part 7 move relative to each other under the drive of the rotating mechanism 8, and can make the upsetting cavity 2 and the forging cavity 4 contact one by one after rotating 90°. After the upsetting cavity 2 and the forging cavity 4 contact, the rotating mechanism 8 simultaneously drives the upsetting bearing part 6 and the forging bearing part 7 to deflect and move toward the initial position of the forging bearing part 7, so that after the upsetting forging in the upsetting cavity 2 enters the forging cavity 4, the upsetting bearing part 6 and the forging bearing part 7 are driven to return to their initial positions respectively.

[0051] When the present invention is in use, according to the process shown in Example 1, the rotating mechanism 8 in the material moving device 5 drives the upsetting bearing component 6 and the forging bearing component 7 to be placed on both sides of the rotation center, so that the upsetting die 1 and the forging die 3 are stably placed, and the heated aluminum alloy rod is placed into the multiple upsetting cavities 2 in the upsetting die 1 for forming and upsetting.

[0052] After upsetting is completed, the upsetting bearing component 6 and the forging bearing component 7 are simultaneously driven by the rotating mechanism 8 to rotate toward each other around two horizontal center lines until the upsetting cavity 2 and the forging cavity 4 correspond one to one, and then the upsetting bearing component 6 and the forging bearing component 7 are simultaneously driven to rotate toward the initial position of the forging die 3 for forging until the placement orientation of the forging die is the same as the initial position, so that the upsetting forging in the upsetting cavity 2 is transferred to the inside of the forging cavity 4 under the action of gravity, and then the rotating mechanism 8 drives the upsetting bearing component 6 to return to the initial position for the next round of upsetting forging.

[0053] And because the upsetting bearing component 6 and the forging bearing component 7 rotate at the same time and the corresponding states of the upsetting die 1 and the forging die 3 need to be kept unchanged, it is necessary to drive the upsetting bearing component 6 and the forging bearing component 7 to deflect in the same direction at the same time, so that the forging bearing component 7 cannot be completely reset to the initial position when it deflects toward the initial position. Therefore, after the transfer is completed, the upsetting bearing component 6 and the forging bearing component 7 need to be reset again by the rotating mechanism 8 to ensure that both are completely reset for upsetting forging and forming forging.

[0054] In this embodiment, the rotation center of the rotating mechanism 8 is parallel to the horizontal plane.

[0055] The rotating mechanism 8 includes a processing table 801 and a base rotating device 802 arranged on the processing table 801, a rotating base 803 is arranged on the base rotating device 802, and two symmetrical rotating devices 804 about the center of the rotating base 803 are arranged on the rotating base 803. Each symmetrical rotating device 804 is provided with a supporting plate 805 for installing the upsetting supporting component 6 or the forging supporting component 7, and a positioning and lifting device 806 is provided on one side of each supporting plate 805 and the processing table 801.

[0056] Among them, the rotation centers of the base rotating device 802 and the counter-rotating device 804 are parallel and parallel to the surface of the processing table 801, and when the two counter-rotating devices 804 move toward each other until they are perpendicular to the processing table 1, the upsetting die 1 and the forging die 3 come into contact, and the two counter-rotating devices 804 are simultaneously controlled by the base rotating device 802 to rotate to the side where the forging die 3 is located during forging, and the positioning and lifting device 806 is used to lift the supporting plate 805 when it is reset and press down to fix the supporting plate 805 after positioning it by squeezing the circumference.

[0057] When the rotating mechanism 8 is in use, when forging the materials in the roughing die 1 and the forging die 3, the two supporting plates 805 are parallel to the surface of the processing table 1 and are symmetrically arranged on both sides of the rotating base 803. The supporting plates 805 are positioned and fixed by the supporting of the processing table 1 and the positioning and lifting device 806 to ensure stable forging of the roughing die 1 and the forging die 3 and ensure forging accuracy.

[0058] When transferring the upsetting forging in the upsetting die 1, the two counter-rotating devices 804 simultaneously drive the two supporting plates 805 to rotate toward each other to the surface of the vertical processing table 1, so that the upsetting cavity 2 and the forging cavity 4 correspond one to one and remain stationary, and then the base rotating device 802 drives the rotating base 803 to rotate toward the direction of the initial position of the forging die 3, so that the two counter-rotating devices 804 and the upsetting die 1 and the forging die 3 all rotate synchronously.

[0059] When the supporting plate 805 on which the forging die 3 is located rotates to the maximum angle, the base rotating device 802 stops rotating. At this time, the upsetting forging in the upsetting die 1 is transferred to the forging die 3 under the action of gravity, and then the base rotating device 802 is driven to rotate in the opposite direction for reset.

[0060] At this time, the base rotating device 802 is used to drive the rotating base 803 to reset, thereby driving the supporting plate 805 with the forging die 3 to reset and fix it through the positioning and lifting device 806, and then the supporting plate 805 with the upsetting die 1 is driven to reset through the positioning rotating device 804, and the supporting plate 805 is also positioned and fixed through the positioning and lifting device 806, ensuring that the upsetting die 1 and the forging die 3 are in a fixed position after each reset, avoiding the problem that position deviation affects the forging process and causes damage to the upsetting die 1 and the forging die 3.

[0061] The positioning and lifting device 806 presses down the supporting plate 805 to prevent the supporting plate 805 from shaking up and down during the forging process, thereby affecting the forging accuracy and forging quality.

[0062] The positioning and lifting device 806 includes a square bracket 807 arranged on the processing table 1, and the inner side walls of the square bracket 807 are provided with a top-pressing positioning structure 808 that moves in a direction parallel to the processing table 1, wherein a downward pressing structure 809 is provided on the two relatively moving top-pressing positioning structures 808.

[0063] A bracket 810 for being engaged with the square bracket 807 is provided on one side of the supporting plate 805, and a plurality of side pressure grooves 811 are provided on the peripheral side of the bracket 810, and the top-pressing positioning structure 808 presses the side wall of the bracket 810 to a preset fixed position in the square bracket 807, and the downward pressing structure 809 is used to press the side wall of the side pressure groove 811 in a direction perpendicular to the surface of the processing table 1.

[0064] When the positioning and lifting device 806 is in use, when the supporting plate 805 is reset to its initial position, the bracket 810 is located inside the square bracket 807, and the surrounding side of the bracket 810 is pressed to a preset fixed position by the top-pressing positioning structure 808 on the four side walls, thereby ensuring that the positions of the upsetting die 1 and the forging die 3 are the same before and after reset, avoiding forging errors that affect the forging quality.

[0065] While the pressing and positioning structure 808 is pressing the bracket 810 outward, the pressing structure 809 enters the side pressing groove 811 and presses down the side wall of the side pressing groove 811 to limit the up and down shaking of the bearing plate 805 and affect the forging quality.

[0066] The top-pressing positioning structure 808 includes a side groove 812 arranged on one side of the bracket 807, a telescopic component 813 is provided at the inner bottom of the side groove 812, a top plate 814 is provided at the end of the telescopic component 813 and is slidably connected to the inner wall of the side groove 812, a straight groove 815 is provided on the side wall parallel to the movement direction of the top plate 814 and the telescopic component 813, a preset baffle 816 is provided on the inner wall of the side groove 812 and is slidably connected to the inner wall of the straight groove 815, and the fixed position of the preset supporting plate 805 is counteracted by the preset baffle 816 and the inner wall of the straight groove 815.

[0067] When the top pressure positioning structure 808 is in use, the telescopic component 813 drives the top plate 814 to slide along the side groove 812 until it is against the bracket 810. When the preset baffle 816 is in the process of the top plate 814 moving toward the outside of the side groove 812 and is against the inner wall of the straight groove 815, it reaches the preset fixed position. The top pressure of multiple top plates 814 ensures that the bracket 810 is always fixed in the same position when it is reset, ensuring the accurate position of the roughing die 1 and the forging die 3 during forging, avoiding the problem of forging error caused by position error, thereby affecting the forging quality, and even causing direct contact with the roughing die 1 or the forging die 3 during forging, causing damage to the roughing die 1 or the forging die 3.

[0068] The pressing structure 809 includes a lifting device 817 provided on one side of the top plate 814 and moving in a direction perpendicular to the surface of the processing table 1 , and a pressing plate 818 is provided at the end of the lifting device 817 .

[0069] When the downward pressure structure 809 is in use, the lifting device 817 drives the pressure plate 818 to descend until it is against the side wall of the side pressure groove 811, and the side groove 812 limits the up and down movement of the top plate 814, thereby limiting the up and down movement of the pressure plate 818 and the lifting device 817 when the lifting device 817 is not in operation, thereby ensuring the stability of the upsetting die 1 and the forging die 3 during forging.

[0070] A side plate 826 perpendicular to the processing table 1 is provided on the processing table 1 , a rotating assembly 819 is provided on the side plate 826 , and an elastic plate 820 for striking the supporting plate 805 where the upsetting die 1 is located is connected to the rotating assembly 819 .

[0071] The elastic plate 820 is driven by the rotating assembly 819 to rotate cyclically to continuously strike the supporting plate 805, thereby generating vibration on the supporting plate 805 to assist in transferring the upsetting forging in the upsetting die 1 to the forging die 3, and the elastic plate 820 generates elastic deformation and bending when striking the supporting plate 805 and rotates cyclically through the obstruction of the supporting plate 805, and the side plate 826 provides support.

[0072] The end of the elastic plate 820 is rotatably connected to a counterweight roller 821 , the surface of which is covered with an elastic pad 822 , and the rotation center of the counterweight roller 821 is perpendicular to the rotation center of the rotating assembly 819 and parallel to the supporting plate 805 .

[0073] By providing the counterweight roller 821 , the force exerted by the elastic plate 820 when striking the bearing plate 805 is increased, further ensuring that the upset forging is transferred to the interior of the forging die 3 , thereby improving the efficiency and effectiveness of the transfer.

[0074] The rotation center of the counterweight roller 821 is parallel to the rotation center of the rotating assembly 819 and parallel to the supporting plate 805, thereby ensuring that the upsetting forging in the upsetting die 1 has the maximum effect when subjected to gravity, and making the counterweight roller 821 fit the supporting plate 805 when striking the supporting plate 805 to obtain the maximum striking effect.

[0075] The elastic pad 822 is provided to reduce the noise generated.

[0076] The rotating base 803 includes a base body 823 connected to the base rotating device 802, and a telescopic component 813 is also vertically arranged on the outer side of the base body 823. An insert plate 824 is arranged at the end of the telescopic component 813. The surface of the processing table 1 is provided with a slot 825 for slidingly inserting with the insert plate 824, and when both supporting plates 805 are fixed, the insert plate 824 is inserted into the slot 825 through the telescopic component 813.

[0077] When the seat body 823 is in the initial position, that is, the two supporting plates 805 are symmetrically located on both sides of the seat body 823 and are fixed, the telescopic assembly drives the insert plate 824 to slide and insert into the slot 825 to limit the movement of the seat body 823, thereby preventing the rotating base 803 from being vibrated during the forging process and affecting the stability of the supporting plate 805.

[0078] In this embodiment, the base rotation device 802, the positioning rotation device 804 and the rotating assembly are all mechanical structures that drive the corresponding structures to rotate, such as directly driven by a motor, etc. The lifting device 817 and the telescopic assembly 813 are both mechanical structures that can move in a straight line, such as an electric push rod or a hydraulic push rod.

[0079] In this embodiment, the upsetting bearing member 6 and the forging bearing member 7 are mechanical structures for fixing the upsetting die 1 and the forging die 3 respectively, and they only need to play a fixing role.

[0080] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
