[0025] 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.

[0026] See also Figure 1 In an embodiment of the present invention, a stamping and forming device for processing a resistor aluminum shell includes a base 1, a die groove 3 is opened in the middle of the base 1, a lower die table 4 is fixedly installed in the middle of the inner wall of the die groove 3, the lower die table 4 is configured as a cubical boss, and the size of the lower die table 4 is consistent with the size of the inner cavity of the resistor aluminum shell to be processed, a mounting frame 2 is provided above the base 1, a plurality of lifting guide columns 103 are fixedly connected to the bottom edge of the mounting frame 2, the bottom of the lifting guide column 103 is slidably connected to the base 1, a stamping drive mechanism is fixedly installed inside the base 1, the stamping drive mechanism is implemented by the existing technical means, and the stamping operation of the aluminum shell is realized by driving the mounting frame 2 to move up and down by the stamping drive mechanism, an upper die table 6 is fixedly installed in the middle of the mounting frame 2, and the stamping forming of the aluminum shell is realized by pressing the upper die table 6 and the lower die table 4;

[0027] The lower die table 4 is protruding upward and the top of the lower die table 4 is provided with an oil inlet hole 701 for introducing stamping oil. Figure 4 An oil storage tank 703 is fixedly installed on one side of the base 1, and an oil guide pipe 702 is fixedly connected to the bottom of one side of the oil storage tank 703.

One end of the lower oil pipe is fixedly connected to the bottom of the oil inlet hole 701, and the upper oil pipe is fixedly connected to one side of the inner cavity of the upper die table 6; the stamping oil is transported to the top of the lower die table 4 by setting the oil inlet hole 701. Aluminum alloy is a good conductor of heat, which is easy to conduct heat and also easy to generate heat. Therefore, during stamping, it is necessary to frequently apply stretching oil or stamping oil on the material and the mold to cool down and lubricate, and reduce friction and wear between the aluminum shell and the mold.

[0028] See also Figure 1 and Figure 2The top of the lifting frame 502 is fixedly connected to the lifting gasket 503, and the bottom of the lifting frame 502 is provided with an electric push rod 501.

During the lifting process, negative pressure is generated between the aluminum shell and the lower die table 4 and the upper die table 6, thereby sucking out the stamping oil in the upper and lower oil pipes, so that it naturally flows and moistens the inner cavity of the upper die table 6 and the top surface of the lower die table 4 and the die groove 3, thereby achieving cooling and lubrication of the subsequent aluminum material and die table.

[0030] See also Figure 1 and Figure 5 A boss is provided on one side of the die groove 3, and a side air supply component 9 is fixedly installed on one side of the boss.

A side plate air supply pipe 903 is fixedly connected to one side of the air supply frame 901. Air is supplied to the die groove 3 through the side air supply component 9 to further dissipate the heat of the die groove 3 and at the same time assist the flow of the stamping oil to make it evenly distributed.

[0031] See also Figure 3 In order to facilitate the separation of the aluminum shell and the upper mold platform 6, a discharge air supply pipe 904 is fixedly connected to the top of the inner cavity of the upper mold platform 6. One end of the discharge air supply pipe 904 is fixedly connected to the output end of the external air pump. The aluminum shell is blown out of the upper mold platform 6 to achieve separation by supplying air through the discharge air supply pipe 904.

[0032] In order to realize automatic unloading and discharge of the formed aluminum shell, a driving motor 801 is fixedly installed on one side of the bottom of the mounting frame 2, and the output end of the driving motor 801 is fixedly connected to the unloading frame 802, and the middle part of the unloading frame 802 is fixedly connected to the unloading push plate 803.

A unloading trough 105 is opened on one side of the top of the base 1. The unloading frame 802 is driven to rotate by the driving motor 801, and the unloading push plate 803 is used to push and discharge the aluminum shell placed on the lifting washer 503 of the unloading mechanism, so that it falls into the unloading trough 105 and is sent out.

[0033] See also Figure 1 In order to realize the automatic conveying and loading of aluminum materials, a loading trough 101 is opened at one end of the top of the base 1, and a plurality of loading rollers 102 are rotatably connected to the inner wall of the loading trough 101.

[0035] During stamping, the stamping drive mechanism drives the mounting frame 2 to move downward, driving the upper die table 6 to move downward and dock with the lower die table 4, pushing the aluminum plate to form an aluminum shell, and then the upper die table 6 is lifted, and at the same time, an external air pump supplies air to the unloading air supply pipe 904 to assist in separating the aluminum shell from the upper die table 6, and then the electric push rod 501 is started, driving the lifting frame 502 and the lifting gasket 503 to lift, lifting the aluminum shell to separate it from the lower die table 4, and in the process of separation of the aluminum shell from the lower die table 4 and the upper die table 6, negative pressure is generated, and the stamping oil in the upper oil pipe and the lower oil pipe is sucked out, and the inner cavity of the upper die table 6 and the top surface of the lower die table 4 and the die groove 3 are naturally flowed and moistened. When the subsequent aluminum plate enters, the stamping oil first contacts the aluminum plate to complete the cooling and lubrication of the aluminum plate;

[0036] Then, the driving motor 801 drives the unloading rack 802 to rotate, and the unloading push plate 803 pushes the aluminum shell to fall into the unloading chute 105 for delivery.
