[0022] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive. Example

[0023] Please refer to the attached Figure 1 , 2, 3, 6, 7, and 8, the present invention provides a battery sheet metal shell forging device for new energy vehicles, including a base 1, a workbench 101 is provided on the base 1, a lower die 5 is provided on the workbench 101, and the lower die 5 is connected to a negative pressure dust suction module 6; the negative pressure dust suction module 6 includes a dust suction duct 602, the inlet of the dust suction duct 602 is in a trumpet shape that can be adjusted at multiple angles, and an electric guide plate 606 and a laser particle size sensor 607 are also provided thereon, and one end of the dust suction duct 602 is connected to the lower die 5 The other end is connected to a filter unit 603, which is connected to a vacuum pump 601 via a connecting pipe 604, and a detachable dust box 605 is provided in the filter unit 603. In addition, the filter unit 603 is a graded filtration system, which includes a metal coarse filter 6031, a metal fine filter 6032 and a nano activated carbon filter 6033 in sequence. The pore size range of the metal coarse filter 6031 is 1-5 mm, and the pore size range of the metal fine filter 6032 is 0.01-0.1 mm.

[0024] It should be noted that during the forging operation, the lower die 5 generates a large amount of waste chips. Since the vacuum pump 601 is continuously running, a negative pressure environment is created in the entire negative pressure dust suction module 6. The waste chips are sucked into the dust suction pipe 602 from the chip discharge port 501. The electric guide plate 606 at the entrance of the dust suction pipe 602 guides the waste chips into the dust suction pipe 602. Under the action of negative pressure suction, the waste chips entering the dust suction pipe 602 move along the dust suction pipe 602 to the filter unit 603. After the waste chips arrive at the filter unit 603, the metal coarse filter 6031 of the filter unit 603 intercepts metal fragments and particles with larger particle sizes. Prevent it from entering the subsequent fine filtration level and avoid clogging or damage to the metal fine filter 6032, while the metal fine filter 6032 captures smaller metal dust. The nano activated carbon filter 6033 can play an adsorption role to adsorb oil, harmful gases and extremely fine dust to achieve deep purification. After passing through these three layers of filters, waste debris and pollutants of different particle sizes and types are gradually intercepted and fall into the dust collection box 605. The air purified by the filter unit 603 continues to flow to the vacuum pump 601 through the connecting pipe 604 under the action of negative pressure, and is finally discharged by the vacuum pump 601.

[0025] It should be noted that the vacuum pump 601 is a small high-suction pump with intelligent frequency conversion and a suction adjustment range of 500-5000Pa. The control system 3 will adjust its suction size in real time according to parameters such as forging frequency and strength, which can not only ensure the dust collection effect but also avoid excessive energy consumption.

[0026] It should be noted that the dust collection duct 602 is made of a flexible ceramic-based composite material with embedded high-strength metal wire. Its inner wall is smooth, which can reduce the retention of waste chips due to friction and maintain smooth transportation. The metal wire is made of stainless steel with a diameter range of 0.5-1.5mm to enhance the duct's resistance to tensile and bending.

[0027] It should be noted that the electric guide vane 606 is made of lightweight high-strength aluminum alloy, and there are 3-5 of them. Each electric guide vane 606 is rotatably connected to the inner wall of the trumpet-shaped entrance of the dust collection pipe 602. According to the waste chip splashing trajectory monitored by the laser particle size sensor 607, the electric guide vane 606 adjusts its angle in real time under the drive of the control system 3, accurately guides the waste chips into the dust collection pipe 602, and prevents the waste chips from escaping. When the laser particle size sensor 607 detects waste chips that do not meet the normal size, the control system 3 will warn the operator to check whether the forging operation is proceeding normally.

[0028] It should be noted that the waste intercepted by the filter, relying on gravity, falls into the dust box 605 along the inclined channel in the filter unit 603, and the bottom of the dust box 605 is an inclined slope with an angle range of 30°-60°, which can guide the waste to gather at the bottom of the box body for centralized processing and recycling. At the same time, a laser level meter 608 is provided inside the dust box 605. The detection error of the laser level meter 608 is ±1mm, which can monitor the accumulation height of waste in real time. When the set threshold is reached, it reminds the staff to clean it up.

[0029] Please refer to the attached Figure 5 As shown, the lower mold 5 is provided with a plurality of chip removal openings 501, which are connected to the dust suction duct 602, and the shape of the chip removal openings 501 is circular, elliptical or slit-shaped, wherein the diameter range of the circular chip removal openings 501 is 3-8mm, the major axis range of the elliptical chip removal openings 501 is 10-20mm, the minor axis range is 5-10mm, and the width range of the slit-shaped chip removal openings 501 is 1-3mm. In addition, the chip removal openings 501 form an angle of 30°-60° with the bottom surface of the lower mold, and the edge roughness is Ra0.8-Ra1.6μm.

[0030] It should be noted that the chip discharge openings 501 of various shapes are based on considerations of the form of chip generation and discharge efficiency. The circular chip discharge opening 501 is suitable for discharging common granular and nearly spherical metal fragments, which can prevent the chips from getting stuck and ensure that the chips quickly enter the dust collection duct 602. The elliptical chip discharge opening 501 is for those long strips and flaky chips, which often appear during forging. The larger long axis provides sufficient space for the chips to slide out without hindrance, and the short axis is limited to a reasonable range to maintain the concentration of the dust suction force. The slit-shaped chip discharge opening 501 is narrow in width, mainly for fine dust or thin flaky tiny waste, concentrating the dust suction airflow to efficiently capture such lightweight and easily floating impurities; and the inclination angle between the chip discharge opening 501 and the bottom surface of the lower die can help the chips flow smoothly into the dust collection duct 602 and work in coordination with the negative pressure suction force.

[0031] It should be noted that the treatment of the surface of the chip removal port 501, on the one hand, avoids excessive smoothness that causes waste chips to adhere to the edge of the chip removal port 501 due to surface tension, electrostatic adsorption and other factors, thereby affecting the discharge efficiency; on the other hand, compared with a rougher surface, it will not cause waste chips to get stuck, thereby ensuring the continuity of the chip removal process.

[0032] Please refer to the attached Figure 1 , 2 As shown in Figures 3 and 4, a forging module 2 is provided above the base 1, and the forging module 2 includes a power unit 201. The power unit 201 adopts a hydraulic drive system, and the power unit 201 is equipped with a pressure sensor 202. The pressure sensor 202 and the power unit 201 are both electrically connected to the control system 3. In addition, the output end of the power unit 201 is connected to the upper mold 4, and the upper mold 4 is located directly above the lower mold 5, and a guide unit 203 is provided between the upper mold 4 and the lower mold 5.

[0033] It should be noted that the pressure sensor 202 is installed on the cylinder barrel of the hydraulic cylinder to monitor the forging pressure in real time and transmit the signal to the control system 3. The control system 3 analyzes and processes the signal according to a preset algorithm, and then adjusts the relevant parameters of the forging power mechanism.

[0034] It should be noted that the guide unit 203 is composed of four guide columns and corresponding guide sleeves. The guide columns are installed at the four corners of the upper mold 4, and the guide sleeves are correspondingly installed on the base 1. During the forging operation, the upper mold 4 reciprocates up and down with the power unit 201. At this time, the guide columns will slide along the inner cavity of the guide sleeve to constrain the movement trajectory of the upper mold 4 to prevent it from shifting in the left and right and front and back directions, ensuring that the upper mold 4 descends vertically and is accurately embedded in the cavity of the lower mold 5, so that each forging action can be carried out stably and accurately.

[0035] Please refer to the attached Figure 1 , 2 As shown in Figures 3 and 4, the base 1 is a rectangular block made of high-strength cast iron, and a control system 3 is provided on the front of the base 1. Rubber shock-absorbing pads 103 are provided at the four corners of the bottom. In addition, a pipeline channel 104 and an electrical line channel 105 are also provided inside the base 1.

[0036] It should be noted that the rubber shock-absorbing pad 102 adopts a multi-layer composite structure, with an outer layer of wear-resistant rubber and an inner layer of damping rubber, which can effectively absorb vibrations in the vertical direction and reduce the strong vibrations generated during forging operations; the pipeline channel 103 is made of metal, with a smooth inner wall and a diameter that matches the outer diameter of the dust collection pipeline 602, to ensure smooth laying of the pipeline without bends and obstacles, and to facilitate later maintenance and pulling; the electrical line 104 channel is composed of a plastic wire trough with a detachable cover to facilitate line laying, maintenance and replacement, and can also play an electromagnetic shielding role to prevent external electromagnetic interference from affecting the communication between the control system 3 and the vacuum pump 601.

[0037] The specific operation process of the present invention is as follows: First, turn on the power of the equipment, and according to the forging process characteristics and raw material conditions of the battery sheet metal shell, set the suction value of the vacuum pump 601 through the control system 3. At the same time, set the data acquisition frequency, sensitivity threshold and other parameters of the laser particle size sensor 607 to ensure that the waste chip information can be accurately captured and the electric guide plate 606 can be driven to work effectively. Then, according to the design specifications of the battery sheet metal shell, input the key parameters such as forging intensity and forging frequency; The negative pressure dust suction module 6 is started, and the vacuum pump 601 starts to work, and negative pressure is quickly formed in the entire dust suction pipe 602 system. At the same time, the power unit 201 of the forging module 2 drives the upper die 4 to slowly move downward to start the forging operation; During the forging process, the operator pays close attention to the monitoring interface of the control system 3. If problems such as abnormal suction force and excessive accumulation of waste chips are found, the suction parameters are adjusted in time. The control system 3 automatically fine-tunes the output of the power unit 201 according to the actual forging force fed back by the pressure sensor 202 and compares it with the preset value to ensure the forging accuracy. The waste chips generated in the lower mold 5 are immediately discharged by the chip discharge port 501 and transported to the filter unit 603 through the dust suction pipe 602. The air purified by the filter unit 603 is discharged to the vacuum pump 601, and the intercepted waste chips fall into the dust collection box 605. At the same time, under the guidance of the guide unit 203, the upper mold 4 and the lower mold 5 continue to complete the mold closing and opening actions again and again, so as to stably produce the battery sheet metal shell; After the forging operation is completed, the device is stopped at the control system 3, the upper mold 4 returns to its initial upper position, the vacuum pump 601 of the negative pressure dust suction module 6 stops running, the entire device gradually stops, and then the dust box 605 is opened, the collected waste chips are dumped into a special waste collection container, the inside of the dust box 605 is cleaned, and then it is put back in place, the main power switch is turned off, and the operation process is ended.

[0038] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
