Description

Technical Field

[0001] The present invention relates to the field of automobile sheet metal stamping, and in particular to an automobile sheet metal stamping device. Background Art

[0002] Automotive sheet metal stamping is a processing method that uses molds and stamping equipment to apply pressure to cause metal sheets to produce plastic deformation, thereby obtaining automotive parts of the desired shape and size.

[0003] The mold usually consists of an upper mold and a lower mold. During the stamping process, the sheet metal material undergoes severe plastic deformation between the upper and lower molds. The upper and lower molds are in close contact with the material surface and move relative to each other, generating friction. To reduce friction and ensure part quality and mold life, the upper and lower molds need to be lubricated with spray lubricant after a preset number of stampings.

[0004] In the prior art, the equipment for spraying lubricating oil on the upper mold and the lower mold includes the use of a spray-type spraying equipment, which sprays lubricating oil on the upper mold and the lower mold by reasonably arranging multiple atomizing nozzles around the upper mold and the lower mold. The lubricating oil is sprayed in the form of mist and adheres to the upper mold and the lower mold. When the mist lubricating oil is sprayed on the upper mold, part of the lubricating oil will fall downward to other places due to gravity, thereby causing certain waste. Moreover, most of the current nozzles are fixed, and the spraying position can only be adjusted by adjusting the angle, etc. There is still room for improvement in the uniformity of spraying on the mold.

[0051] 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. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0052] The invention provides a stamping device for automobile sheet metal parts.

[0054] The lower mold 1 is mounted on the base 10, and the upper mold assembly 2 is mounted on the installation cabinet 20 and suspended above the lower mold 1;

[0055] The horizontal conveying device 6 is installed on the installation cabinet 20 through the first installation plate 30 and is arranged adjacent to the lower mold 1;

[0056] The angle adjustment device 4 includes a mounting frame 41, a motor 42 and a mounting tube 43. The mounting frame 41 is mounted on the output end of the horizontal conveying device 6. The motor 42 is mounted on the mounting frame 41. The mounting tube 43 is sleeved on the drive shaft 421 of the motor 42 and is connected to the drive shaft 421 with a sliding key.

[0057] The fuel injection assembly 3 includes an upper fuel injection pipe 31, a lower fuel injection pipe 32, two liquid inlet pipe heads 34, and a plurality of nozzles 33. The upper fuel injection pipe 31 and the lower fuel injection pipe 32 are respectively mounted at both ends of the mounting pipe 43 and are both arranged perpendicular to the mounting pipe 43. The plurality of nozzles 33 are installed at intervals on the top of the upper fuel injection pipe 31 and the bottom of the lower fuel injection pipe 32. The liquid inlet pipe heads 34 are both connected to the upper fuel injection pipe 31 and the lower fuel injection pipe 32.

[0058] The socket part 5 includes a connecting portion 51 and two socket boxes 52. The two socket boxes 52 are installed on both sides of the connecting portion 51. The connecting portion 51 is installed at the bottom of the upper oil injection pipe 31 through a connecting member. The bottom of the connecting portion 51 is connected to an oil drain pipe head 53.

[0059] In this embodiment, the horizontal conveying device 6 is arranged on the back side of the lower mold 1 .

[0060] Please refer to Figure 8 When the upper mold assembly 2 and the lower mold 1 need to be sprayed with lubricating oil, the angle adjustment device 4 drives the mounting tube 43 to rotate counterclockwise by ninety degrees, so that the upper oil spray pipe 31 and the lower oil spray pipe 32 are located between the upper mold assembly 2 and the lower mold 1, and are initially located at one end of the upper mold assembly 2 and the lower mold 1. The horizontal conveying device 6 conveys the angle adjustment device 4, driving the upper oil spray pipe 31 and the lower oil spray pipe 32 to follow the movement, wherein the lubricating oil is sprayed from the nozzle 33 of the upper oil spray pipe 31 to the upper mold assembly 2, and the lubricating oil is sprayed from the nozzle 33 of the lower oil spray pipe 32 to the lower mold 1. Since the horizontal conveying device 6 can convey the upper oil spray pipe 31 and the lower oil spray pipe 32 at a uniform speed, the lubricating oil is sprayed from the nozzle 33 of the upper oil spray pipe 31 to the upper mold assembly 2, and the lubricating oil is sprayed from the nozzle 33 of the lower oil spray pipe 32 to the lower mold 1. 1 and the lower oil spray pipe 32 spray lubricating oil on the upper mold assembly 2 and the lower mold 1, thereby improving the uniformity of lubricating oil spraying, and the distance between the upper mold assembly 2 and the nozzle 33 of the upper oil spray pipe 31 can be adjusted so that the nozzle 33 can be close to the part to be sprayed of the upper mold assembly 2, so that the sprayed atomized oil can better adhere to the upper mold assembly 2, thereby reducing the atomized lubricating oil from falling to other positions. At the same time, by setting the receiving part 5, the two receiving boxes 52 are located on both sides of the upper oil spray pipe 31, which can receive and recover the atomized lubricating oil, thereby further reducing the waste of lubricating oil.

[0061] in, Figure 8 The arrows in the figure indicate that the upper oil spray pipe 31 and the lower oil spray pipe 32 move horizontally between the upper mold assembly 2 and the lower mold 1 to spray lubricating oil on the upper mold assembly 2 and the lower mold 1 respectively.

[0062] Among them, the oil injection assembly 3 also includes a lubricating oil storage container, two flow controllers and two oil pumps (not shown in the figure). The liquid inlet pipe heads 34 of the upper oil injection pipe 31 and the lower oil injection pipe 32 are respectively connected to the output ends of the corresponding oil pumps through oil delivery hoses, and the input ends of the oil pumps are connected to the lubricating oil storage container through pipelines. The oil delivery hoses have sufficient length to meet the distance required for the upper oil injection pipe 31 and the lower oil injection pipe 32 to move. The flow controllers are installed on the corresponding oil delivery pipelines to cooperate with the oil pumps to adjust the flow rate of the injected lubricating oil.

[0063] After the oil spraying of the upper mold assembly 2 and the lower mold 1 is completed, the horizontal conveying device 6 conveys the angle adjustment device 4 to drive the oil spray assembly 3 to move to one side of the lower mold 1 and the upper mold assembly 2, and the angle adjustment device 4 drives the mounting tube 43 to drive the upper oil spray pipe 31 and the lower oil spray pipe 32 to rotate ninety degrees clockwise, so that the upper oil spray pipe 31 and the lower oil spray pipe 32 are retracted to one side of the lower mold 1, so that when the sheet metal product to be processed is processed multiple times, the upper oil spray pipe 31 and the lower oil spray pipe 32 will not affect the loading and unloading of the sheet metal product by the configured automatic loading and unloading equipment (such as a robot, etc.), especially for Figure 1As shown, sheet metal products are loaded and unloaded from the left and right directions of the lower die 1.

[0064] In this embodiment, the nozzle 33 is an atomizing nozzle, and both ends of the upper oil injection pipe 31 and the lower oil injection pipe 32 are blocked.

[0065] As an optional feature of this embodiment, the fuel injection assembly 3 also includes two angle adjustment motors for adjusting the spray angle of the nozzle 33. In this case, both the upper fuel injection pipe 31 and the lower fuel injection pipe 32 are rotatably mounted on the mounting tube 43, and one angle adjustment motor is connected to the upper fuel injection pipe 31 or the lower fuel injection pipe 32 via a gear set. This allows the spray angles of the nozzles 33 on the upper fuel injection pipe 31 and the lower fuel injection pipe 32 to be controlled separately. The angle adjustment motors are mounted on the mounting tube 43 via brackets.

[0066] In this embodiment, the oil drain pipe head 53 in the receiving part 5 is connected to the collecting container through a pipeline. The collecting container can be installed on the mounting frame 41 and located below the oil drain pipe head 53 (not shown in the figure), so that it is convenient to move with the injection assembly 3; the two ends of the connecting part 51 are correspondingly connected to the upper injection pipe 31 through connecting parts, so as not to affect the discharge of the collected lubricating oil through the oil drain pipe head 53.

[0067] The lubricating oil collected in the collection container can then be directly recycled and used according to the test results after testing, or can be continued to be used after treatment.

[0068] In this embodiment, the mounting frame 41 is a C-shaped frame, the motor 42 is mounted on the top of the mounting frame 41 , and the driving shaft 421 passes through the top of the mounting frame 41 and is rotatably connected to the bottom of the mounting frame 41 .

[0069] In other embodiments, the mounting frame 41 may also be an L-shaped frame. In this case, the motor 42 is installed at the bottom of the mounting frame 41 , and the drive shaft 421 passes through the bottom of the L-shaped frame.

[0070] See also Figure 1 and Figure 2 The upper mold assembly 2 includes a hydraulic device 21, an upper mold part 22 and a positioning sleeve 23. The hydraulic device 21 is installed inside the installation cabinet 20. The output end of the hydraulic device 21 passes through the bottom of the installation cabinet 20 and is connected to the upper mold part 22. Positioning sleeves 23 are installed at the four corners of the upper mold part 22. A plurality of limiting columns 201 are installed at the bottom of the installation cabinet 20, and a plurality of positioning columns 11 are installed on the top of the base 10. The positioning columns 11, the limiting columns 201 and the positioning sleeves 23 are arranged in a one-to-one correspondence, and the positioning sleeves 23 are sleeved on the limiting columns 201.

[0071] The hydraulic equipment 21 controls the lifting and lowering of the upper mold 22 and provides downward pressure; by setting the positioning column 11, the positioning sleeve 23 and the limiting column 201, when the hydraulic equipment 21 pushes the upper mold 22 downward, the positioning sleeve 23 moves downward along the limiting column 201. Before the positioning sleeve 23 is separated from the limiting column 201, the bottom end of the positioning sleeve 23 is sleeved on the positioning column 11. Therefore, during the entire process of the upper mold 22 descending, the positioning sleeve 23 can cooperate with the limiting column 201 and the positioning column 11 for guiding and positioning, so that the upper mold 22 can be accurately aligned with the lower mold 1 for stamping and forming the sheet metal part to be processed.

[0072] The shapes of the punch and the cavity of the upper mold 22 and the lower mold 1 are specifically set according to the shape of the automobile parts to be processed, such as automobile engine hoods, doors, trunk lids, mailbox shell protective plates, etc.

[0073] In this embodiment, the upper mold 22 is a male mold and the lower mold 1 is a female mold;

[0074] The upper mold 22 includes an assembly plate and a punch module. The punch module is installed at the output end of the hydraulic equipment 21 through the assembly plate. Four positioning sleeves 23 are installed at the four corners of the assembly plate respectively. The rectangle formed by the center line of the four positioning sleeves 23 is larger than the area of ​​the punch module, and the rectangle formed by the center line of the corresponding four positioning columns 11 is larger than the mold cavity area of ​​the lower mold 1, so as not to affect the automatic loading and unloading of the processed sheet metal products by the automatic loading and unloading equipment.

[0075] The bottom of the installation cabinet 20 is supported by four legs, and the distance between two adjacent legs is greater than the length of the upper mold assembly 2 and the lower mold 1.

[0076] Preferably, each limiting column 201 is sleeved with a spring 12 , which buffers and absorbs the impact force of the upper mold assembly 2 when the hydraulic equipment 21 pushes down the upper mold 22 to interact with the lower mold 1 .

[0077] See also Figure 2 and Figure 3 As a preferred embodiment of this embodiment, the automobile sheet metal stamping device also includes a second mounting plate 40, which is installed on the mounting cabinet 20 and is located below the first mounting plate 30, and the bottom of the mounting frame 41 is slidably connected to the first mounting plate 30.

[0078] By slidingly connecting the mounting frame 41 to the first mounting plate 30, the first mounting plate 30 supports the mounting frame 41, thereby improving the stability of the mounting frame 41 during the movement following the horizontal conveying device 6, that is, improving the stability of the oil spraying assembly 3 in spraying lubricating oil.

[0079] A slide rail is provided on the second mounting plate 40 , and a corresponding slide sleeve is provided at the bottom of the mounting frame 41 , and a pulley is installed inside the slide sleeve. The slide sleeve is sleeved on the slide rail, and the pulley slides into the slide cavity of the slide rail.

[0080] See also Figures 4 to 6 As a preferred embodiment of this embodiment, the connecting portion 51 is made of a deformable material, an arc-shaped hole 521 is provided on the receiving box 52, and the automobile sheet metal stamping device further includes a folding device 7, which is used to drive the two receiving boxes 52 to rotate.

[0081] By setting the connecting portion 51 to a deformable material, after the oil spraying assembly 3 finishes spraying lubricating oil on the upper mold assembly 2 and the lower mold 1, the folding device 7 can drive the two receiving boxes 52 to rotate upward and close together. Figure 7 (a) By closing the two receiving boxes 52 together, the lubricating oil collected and attached to the wall of the receiving box 52 can quickly flow to the connecting portion 51 and then be quickly discharged through the oil drain pipe head 53;

[0082] At the same time, since the nozzle 33 on the upper oil injection pipe 31 opens upward and dust is easily dropped in, the two receiving boxes 52 are closed together to protect the nozzle 33 on the upper oil injection pipe 31, preventing dust from falling onto the nozzle 33 and into the interior of the two receiving boxes 52, thereby contaminating the collected lubricating oil;

[0083] The connecting portion 51 may be made of rubber, silicone, leather, or the like, and both ends of the connecting portion 51 are provided with flanges pointing upwards to prevent the collected lubricating oil from flowing out through the two ends of the connecting portion 51 .

[0084] As an optional method of this embodiment, the folding device 7 includes a fixed frame, two rotating motors, two transmission members and two rotating shafts (not shown in the figure). The fixed frame is installed on the mounting tube 43, the two rotating motors are installed on both sides of the fixed frame, and the two rotating shafts are correspondingly installed on the outer bottom of the two receiving boxes 52. Each rotating shaft is connected to the output shaft of the corresponding rotating motor through the corresponding transmission member, and the two rotating motors are used to drive the two receiving boxes 52 to rotate to achieve opening and closing.

[0085] The transmission parts can be a belt and a pulley or a synchronous wheel and a synchronous belt, etc.

[0086] See also Figure 4 and Figure 5 As another optional method of this embodiment, the folding device 7 includes a connecting handle 71, a lifting device 73 and two support rods 72. The two support rods 72 are installed at both ends of the connecting handle 71, and the two support rods 72 are respectively located on both sides of the upper oil injection pipe 31. The lifting device 73 is used to lift the connecting handle 71.

[0087] When the two receiving boxes 52 need to be closed, the lifting device 73 lifts the connecting handle 71, and the connecting handle 71 drives the two supporting rods 72 to move upward. The two supporting rods 72 correspondingly lift the two receiving boxes 52, so that the two receiving boxes 52 rotate upward and close. The arc-shaped hole 521 on the receiving box 52 is sleeved on the upper fuel injection pipe 31, and the connecting portion 51 covers the upper fuel injection pipe 31 upward.

[0088] When the lower mold 1 and the upper mold assembly 2 are sprayed with lubricating oil, the lifting device 73 lowers the connecting handle 71, driving the two support rods 72 to lower. At this time, the two receiving boxes 52 rotate downward and unfold under the gravity and the elastic restoring force of the connecting part 51. Figure 7 As shown in (b); after the two receiving boxes 52 are opened, the two support rods 72 support the two receiving boxes 52.

[0089] The entire folding device 7 is simplified, and the folding device 7 is easier to install and configure.

[0090] In this embodiment, the side walls of the two receiving boxes 52 are slightly inclined to form an inverted eight-shape, which cooperates with the elastic restoring force of the connecting part 51. Therefore, after the two support rods 72 are lowered, the two receiving boxes 52 are more likely to rotate downward by gravity to achieve the purpose of opening.

[0091] As an optional method of this embodiment, the lifting device 73 is a cylinder or a hydraulic cylinder, etc. The lifting device 73 is installed on the mounting tube 43 through a fixing frame, and the output end of the lifting device 73 is connected to the connecting handle 71.

[0092] See also Figure 5 As another optional embodiment of this embodiment, the lifting device 73 includes a threaded shaft 731, a nut 732, a slide bar 734, two clamping blocks 733 and a rotating device 735. The threaded shaft 731 is rotatably mounted on the second mounting plate 40. The nut 732 is threadedly connected to the threaded shaft 731. The slide bar 734 is mounted on the first mounting plate 30 through a mounting block. The nut 732 is sleeved on the slide bar 734 through an ear. The two clamping blocks 733 are installed on the nut 732 at intervals and are located on the upper and lower sides of the connecting handle 71. The rotating device 735 is used to drive the threaded shaft 731 to rotate.

[0093] The automobile sheet metal stamping device also includes a support member 8, which includes a support plate 81 and a positioning rod 82. The support plate 81 is sleeved and fixed on the mounting tube 43, the bottom end of the positioning rod 82 is installed on the support plate 81, and the top end of the positioning rod 82 passes through the connecting handle 71.

[0094] A clamping cavity is formed between the two clamping blocks 733 .

[0095] By adopting a threaded lifting structure, the use of hydraulic cylinders, air cylinders, etc. is avoided, so there is no need to equip hydraulic stations, air pressure stations, etc., which simplifies the driving equipment and eliminates the need for the configuration of oil pipes or air pipes, thereby avoiding the oil pipes or air pipes from getting entangled or folded when the angle adjustment device 4 rotates and the horizontal conveying device 6 is transported. By setting the lifting device 73 on the second mounting plate 40 and avoiding installation on the mounting pipe 43, the load on the angle adjustment device 4 and the horizontal conveying device 6 can be reduced.

[0096] When the two receiving boxes 52 need to be closed, the spraying of lubricating oil on the upper mold assembly 2 and the lower mold 1 is completed, and the angle adjustment device 4 rotates the upper oil spray pipe 31 and the lower oil spray pipe 32 ninety degrees to one side of the lower mold 1, and the connecting handle 71 faces the clamping cavity. At this time, the horizontal conveying device 6 conveys the oil spray assembly 3 toward the clamping block 733, so that the connecting handle 71 is inserted into the clamping cavity.

[0097] Then, the rotating device 735 drives the threaded shaft 731 to rotate clockwise, and the nut 732 drives the clamping block 733 to move upward along the slide rod 734, thereby driving the connecting handle 71 to move upward. The connecting handle 71 drives the two supporting rods 72 to move upward, pushing the two receiving boxes 52 to rotate upward and close; wherein, the connecting handle 71 moves upward along the positioning rod 82;

[0098] When the two receiving boxes 52 need to be unfolded later, the rotating device 735 drives the threaded shaft 731 to rotate in the opposite direction. At this time, the nut 732 drives the clamping block 733 to move downward, and the clamping block 733 drives the connecting handle 71 to move downward. The two support rods 72 are lowered. At this time, the two receiving boxes 52 rotate downward to unfold. The connecting handle 71 drives the support rod 72 to move downward to the support plate 81. The support plate 81 supports the connecting handle 71 and the support rod 72. Figure 10 (a) to Figure 10 (b).

[0099] As a preferred method of this example, the groove spacing of the clamping cavity is greater than the thickness value of the connecting handle 71, and a convex shaft is provided on the clamping block 733 located below, and a corresponding assembly groove is opened on the connecting handle 71. When the connecting handle 71 is lifted by the clamping block 733 below, the convex shaft is first inserted into the assembly groove, thereby being able to drive the connecting handle 71 to move upward more stably.

[0100] See also Figure 4 and Figure 5 As a preferred embodiment of the present invention, the number of the positioning rods 82 is set to be multiple, and the multiple positioning rods 82 are installed on the support plate 81 at intervals, and the multiple positioning rods 82 pass through the support rod 72 and the connecting handle 71 respectively.

[0101] By providing a plurality of positioning rods 82 to limit the support rod 72 and the connecting handle 71 , the stability of the connecting handle 71 and the support rod 72 during vertical movement is improved.

[0102] In this embodiment, there are four positioning rods 82 , which are respectively located at the four corners of the support plate 81 and correspondingly pass through the two support rods 72 and the two sides of the connecting handle 71 .

[0103] As an optional method in this example, the rotating device 735 includes a bracket, a drive motor and a gear set. The drive motor is mounted on the second mounting plate 40 through the bracket, and the output shaft of the drive motor is set downward. The gear set transmits the output shaft of the drive motor to the threaded shaft 731.

[0104] Please refer again Figure 5 As another optional embodiment of this embodiment, the rotating device 735 is a slave gear, which is installed at the bottom of the threaded shaft 731. The main gear 44 is installed at the bottom end of the drive shaft 421 and below the mounting tube 43. A plurality of sliders 422 are installed around the drive shaft 421 and above the main gear 44. A plurality of key slots 432 are provided at the bottom of the mounting tube 43 corresponding to the sliders 422. The key slots 432 are sleeved on the sliders 422 to form a sliding key connection. The bottom end of the mounting tube 43 is installed with a driving plate 431.

[0105] The automobile sheet metal stamping device further includes an F-shaped frame 9, one end of which is mounted on the first mounting plate 30, and the ends of the two supporting arms 91 of the F-shaped frame 9 are both configured as inclined surfaces;

[0106] When the horizontal conveying device 6 conveys the angle adjustment device 4, so that the angle adjustment device 4 drives the connecting handle 71 to be inserted between the two clamping blocks 733 through the support member 8, the main gear 44 engages with the rotating device 735, and the two support arms 91 of the F-shaped frame 9 are mounted on the drive shaft 421 and push up the driving disk 431 to separate the mounting tube 43 from the slider 422.

[0107] Please refer to Figure 9 and Figure 10 After the lubricating oil coating is completed, the angle adjustment device 4 rotates the upper oil spray pipe 31 and the lower oil spray pipe 32 by 90 degrees so that they are located on one side of the lower mold 1. At this time, the connecting handle 71 faces the clamping cavity, and the horizontal conveying device 6 continues to convey the rotating device 735, driving the connecting handle 71 to be inserted into the clamping cavity through the support member 8. At the same time, the main gear 44 engages with the rotating device 735 (slave gear), and in this process, the inclined surfaces of the ends of the two support arms 91 of the F-shaped frame 9 push the two sides of the driving plate 431, and the driving plate 431 drives the mounting tube 43 to move upward, so that the key groove 432 on the mounting tube 43 is separated from the slider 422; the support arm 91 is supported by the driving plate 431, thereby supporting the mounting tube 43;

[0108] When the subsequent motor 42 drives the drive shaft 421 to rotate again, the drive shaft 421 drives the main gear 44 to rotate, and the main gear 44 drives the threaded shaft 731 to rotate through the rotating device 735 (slave gear), thereby driving the connecting handle 71 to rise and fall, and realizing the function of driving the two receiving boxes 52 to open and close; at this time, the mounting tube 43 does not rotate.

[0109] Subsequently, the horizontal conveying device 6 conveys the angle adjustment device 4 away from the lifting device 73, so that the main gear 44 is separated from the rotating device 735 (slave gear), the connecting handle 71 is separated from the clamping cavity, and the F-shaped frame 9 is separated from the driving plate 431, so that the mounting tube 43 descends, and the key slot 432 is again set on the slider 422 to realize the sliding key connection. Subsequently, the driving shaft 421 can drive the mounting tube 43 to rotate again, as shown in FIG. Figure 10 (c).

[0110] in, Figure 10 The downward arrow in (c) indicates that the F-shaped frame 9 is separated from the driving plate 431, and the mounting tube 43 descends due to gravity. The rotating arrow indicates that the subsequent driving shaft 421 can drive the mounting tube 43 to rotate again.

[0111] Therefore, in this embodiment, the angle adjustment device 4 has the function of driving the upper oil injection pipe 31 and the lower oil injection pipe 32 to rotate and adjust their positions, and driving the threaded shaft 731 to rotate to realize the function of driving the two receiving boxes 52 to open and close, and the switching of the two functions is achieved in the process of the horizontal conveying device 6 conveying the angle adjustment device 4, inserting the connecting handle 71 into the clamping cavity, the main gear 44 engaging with the rotating device 735 (slave gear), and the inclined surfaces of the ends of the two support arms 91 of the F-shaped frame 9 pushing the drive plate 431 to drive the mounting tube 43 to move upward, so that the key slot 432 is separated from the slider 422, and no additional driving equipment is required to switch the functions.

[0112] The number of the sliders 422 is not less than two. In this embodiment, the number of the sliders 422 is four, and the number of the corresponding key slots 432 is four.

[0113] See also Figure 9 A supporting portion is provided at the bottom end of the slider 422 , and when the keyway 432 is assembled with the slider 422 , the supporting portion is used to support the mounting tube 43 .

[0114] By providing the support portion, the bottom end of the mounting tube 43 is prevented from acting on the main gear 44;

[0115] Furthermore, preferably, balls are embedded in the support portion to reduce friction between the mounting tube 43 and the support portion when the mounting tube 43 rotates.

[0116] Please refer again Figure 9The tops of the two arms 91 of the F-shaped frame 9 are both equipped with arc-shaped protrusions 911, and the bottom of the driving plate 431 is correspondingly provided with an arc-shaped groove (not shown in the figure).

[0117] When the support arm 91 supports both sides of the driving disk 431, the arc-shaped protrusion 911 is correspondingly embedded in the arc-shaped groove, thereby having a certain limiting effect on the axial direction of the driving disk 431. Therefore, when the motor 42 drives the main gear 44 to rotate through the drive shaft 421, the mounting tube 43 can be better kept stationary, so that the subsequent key groove 432 can be better aligned with the slider 422.

[0118] Since the arc-shaped protrusion 911 is provided, when the driving plate 431 is separated from the F-shaped frame 9, the arc-shaped protrusion and the groove wall of the arc-shaped groove act to slightly lift the mounting tube 43, so that the arc-shaped protrusion is separated from the arc-shaped groove.

[0119] The inner wall of the mounting tube 43 and the surface of the driving shaft 421 are both smooth.

[0120] In this embodiment, the horizontal conveying device 6 is a belt conveying device, which includes a mounting box, a driving motor, a conveyor belt 61, a connecting block 62 and two pulleys. The mounting box is mounted on the first mounting plate 30. A strip opening is provided on the side of the mounting box facing the angle adjustment device 4. The two pulleys are rotatably mounted on both sides of the inside of the mounting box. The conveyor belt 61 is connected to the two pulleys for transmission. The driving motor is mounted on the mounting box. The output end of the driving motor passes through the mounting box and is connected to a pulley. The connecting block 62 connects the conveyor belt 61 and the mounting frame 41.

[0121] In other embodiments, the horizontal conveying device 6 may also adopt a screw conveying structure, etc.

[0122] The working principle of the automobile sheet metal stamping device provided by the present invention is as follows:

[0123] Please refer to Figure 8 When the upper mold assembly 2 and the lower mold 1 need to be sprayed with lubricating oil, the angle adjustment device 4 drives the mounting tube 43 to rotate counterclockwise by ninety degrees, so that the upper oil spraying pipe 31 and the lower oil spraying pipe 32 are located between the upper mold assembly 2 and the lower mold 1, and are initially located at one end of the upper mold assembly 2 and the lower mold 1. The horizontal conveying device 6 conveys the angle adjustment device 4, driving the upper oil spraying pipe 31 and the lower oil spraying pipe 32 to move accordingly, wherein the lubricating oil is sprayed from the nozzle 33 of the upper oil spraying pipe 31 to the upper mold assembly 2, and the lubricating oil is sprayed from the nozzle 33 of the lower oil spraying pipe 32 to the lower mold 1;

[0124] The two receiving boxes 52 are unfolded and located on both sides of the upper oil injection pipe 31, and can receive and recover the atomized and falling lubricating oil, thereby further reducing the waste of lubricating oil.

[0125] Please refer to Figure 9 and Figure 10After the lubricating oil coating is completed, the angle adjustment device 4 rotates the upper oil spray pipe 31 and the lower oil spray pipe 32 by 90 degrees so that they are located on one side of the lower mold 1. At this time, the connecting handle 71 faces the clamping cavity, and the horizontal conveying device 6 continues to convey the rotating device 735, driving the connecting handle 71 to be inserted into the clamping cavity through the support member 8. At the same time, the main gear 44 engages with the rotating device 735 (slave gear), and in this process, the inclined surfaces of the ends of the two support arms 91 of the F-shaped frame 9 push the two sides of the driving plate 431, and the driving plate 431 drives the mounting tube 43 to move upward, so that the key groove 432 on the mounting tube 43 is separated from the slider 422; the support arm 91 is supported by the driving plate 431, thereby supporting the mounting tube 43;

[0126] When the subsequent motor 42 drives the drive shaft 421 to rotate again, the drive shaft 421 drives the main gear 44 to rotate, and the main gear 44 drives the threaded shaft 731 to rotate through the rotating device 735 (slave gear), thereby driving the connecting handle 71 to rise and fall, and realizing the function of driving the two receiving boxes 52 to open and close; at this time, the mounting tube 43 does not rotate.

[0127] Specifically, the threaded shaft 731 rotates clockwise, and the nut 732 drives the clamping block 733 to move upward along the slide rod 734, thereby driving the connecting handle 71 to move upward. The connecting handle 71 drives the two support rods 72 to move upward, pushing the two receiving boxes 52 to rotate upward and close. The arc-shaped hole 521 on the receiving box 52 is sleeved on the upper fuel injection pipe 31, and the connecting portion 51 covers the upper fuel injection pipe 31 upward, wherein the connecting handle 71 moves upward along the positioning rod 82;

[0128] When the two receiving boxes 52 need to be unfolded later, the threaded shaft 731 rotates in the opposite direction. At this time, the nut 732 drives the clamping block 733 to move downward, and the clamping block 733 drives the connecting handle 71 to descend. The two support rods 72 descend, and the two receiving boxes 52 rotate downward and unfold by gravity and the elastic restoring force of the connecting part 51. Figure 7 As shown in (b); after the two receiving boxes 52 are opened, the two support rods 72 support the two receiving boxes 52. The connecting handle 71 drives the support rod 72 to move down to the support plate 81, and the support plate 81 supports the connecting handle 71 and the support rod 72;

[0129] The subsequent horizontal conveying device 6 conveys the angle adjustment device 4 away from the lifting device 73, so that the main gear 44 is separated from the rotating device 735 (slave gear), the connecting handle 71 is separated from the clamping cavity, and the F-shaped frame 9 is separated from the driving plate 431, so that the mounting tube 43 descends, and the keyway 432 is again mounted on the slider 422 to realize the sliding key connection. The subsequent driving shaft 421 can drive the mounting tube 43 to rotate again to adjust the position of the upper injection pipe 31 and the lower injection pipe 32.

[0130] Therefore, the angle adjustment device 4 has the function of driving the upper oil injection pipe 31 and the lower oil injection pipe 32 to rotate and adjust their positions, and drives the threaded shaft 731 to rotate to realize the function of driving the two receiving boxes 52 to open and close, and the switching of the two functions is achieved in the process of the horizontal conveying device 6 conveying the angle adjustment device 4, inserting the connecting handle 71 into the clamping cavity, the main gear 44 engaging with the rotating device 735 (slave gear), and the inclined surfaces of the ends of the two support arms 91 of the F-shaped frame 9 pushing the drive plate 431 to drive the mounting tube 43 to move upward, so that the key slot 432 is separated from the slider 422, and no additional driving equipment is required to switch the functions.

Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
