Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a stamping forming device for processing an automobile instrument panel. Background Art

[0002] Automobile instrument panel stamping is an important part of automobile manufacturing process, which involves material selection, mold design, stamping process control and other aspects; the material selection of automobile instrument panel is very important, which directly affects the forming quality, performance and cost of stamping parts. In the process of automobile instrument panel stamping, the stamping process parameters need to be strictly controlled to ensure the quality of stamping parts;

[0003] The existing method of processing automobile dashboards is to use a stamping device to stamp a sheet metal plate to obtain a formed automobile dashboard. During the stamping process, due to inaccurate speed control, insufficient or excessive pressure and speed will act on the sheet metal plate, which will easily cause wrinkles on the formed automobile dashboard, thereby affecting the quality of the product. At the same time, during the stamping process of the sheet metal plate, grinding oil is sprayed to reduce the generation of debris. However, if there is too much grinding oil, the lubrication effect may be too strong, resulting in increased fluidity of the sheet metal plate during the stamping process. Excessive fluidity makes the positioning of the sheet metal plate inaccurate, which will also cause wrinkles on the formed automobile dashboard. Summary of the invention

[0004] The technical problems solved by this solution are:

[0005] (1) How to solve the problem that due to inaccurate speed control of stamping, insufficient or excessive pressure and speed are applied to the sheet metal, which easily causes wrinkles on the formed automobile dashboard and affects product quality;

[0006] (2) How to solve the problem that the lubrication effect is too strong, resulting in increased fluidity of the sheet metal during the stamping process, and excessive fluidity causing inaccurate positioning of the sheet metal.

[0007] The object of the present invention can be achieved by the following technical scheme: A stamping forming device for processing an automobile instrument panel, comprising a base and a fixing frame fixedly mounted on the top thereof, a lower die seat fixedly mounted on the base on the front of the fixing frame, a protective mechanism for reducing damage to the automobile instrument panel is arranged on one side of the lower die seat, a punching head is arranged between the base and the fixing frame, and a blower mechanism for adjusting the grinding oil at the bottom of the punching head is arranged above the protective mechanism;

[0008] The protection mechanism includes a sliding plate slidably connected to the base through a guide rail, an L-shaped support frame is fixedly installed on the top of the sliding plate, and a flip unit for heating the sheet metal plate is provided on the side of the L-shaped support frame close to the lower mold base, and the position of the sliding plate corresponds to the position of the lower mold base.

[0009] A further technical improvement of the present invention is that a transversely arranged cylinder is fixedly installed on the base, the protruding end of the cylinder movably passes through the L-shaped support frame and is rotatably connected to a roller, and a baffle is also fixedly installed on the protruding end of the cylinder, and a first tension spring is fixedly connected between the baffle and the middle part of the L-shaped support frame.

[0010] A further technical improvement of the present invention is that a material storage trough is fixedly provided on the top of the L-shaped support frame, the material storage trough is filled with a sufficient amount of grinding oil, and the position of the material storage trough corresponds to the position of the punch head.

[0011] The further technical improvement of the present invention lies in that: the flip unit comprises an L-shaped flip rod rotatably connected to the sliding plate, one end of the L-shaped flip rod is fixedly connected to an electric heating ring through a connecting frame, and the middle part of the L-shaped flip rod is rollingly connected to the roller, and a second tension spring is fixedly connected between the L-shaped support frame and the end of the L-shaped flip rod away from the connecting frame; the extended end of the cylinder is controlled to extend to the longest, and during this process, the baffle cooperates with the first tension spring to drive the sliding plate to move, and after the sliding plate contacts the lower die seat, the extended end of the cylinder continues to extend, and a rolling thrust is provided to the L-shaped flip rod through the roller, so that the L-shaped flip rod flips, and the electric heating ring fits the sheet metal plate on the lower die seat, and the electric heating ring is turned on to heat the part of the sheet metal plate that needs to be stamped, thereby reducing the probability of wrinkles during the stamping process.

[0012] A further technical improvement of the present invention is that the hair blowing mechanism includes an adjusting cylinder fixedly connected to an L-shaped support frame, the top of the side of the adjusting cylinder is connected to a first air outlet pipe, the output end of the first air outlet pipe is connected to a hose, the end of the hose away from the first air outlet pipe is fixedly mounted on the L-shaped support frame through a positioning plate, and the position of the hose output end corresponds to the position of the stamping head, and a control unit for adjusting the direction of airflow is provided under the adjusting cylinder.

[0013] A further technical improvement of the present invention is that: the bottom of the side of the regulating cylinder away from the first air outlet pipe is connected to a second air outlet pipe, and the output end of the second air outlet pipe is arranged toward the middle of the sheet metal plate.

[0014] A further technical improvement of the present invention is that a hot air blower is fixedly installed on the top of the fixing frame, and an output end of the hot air blower is fixedly connected to an air intake pipe, which passes through the fixing frame and is connected to the middle of the regulating cylinder.

When the extended end of the hydraulic cylinder reaches the set length, the bottom of the punching head is immersed in the grinding oil in the storage tank, and the grinding oil will adhere to the bottom of the punching head. Due to the high temperature of the punching head, the viscosity of the grinding oil on its surface is reduced, so as to avoid excessive grinding oil adhering to the bottom of the punching head. When stamping the sheet metal plate, the grinding oil is prevented from directly flushing the sheet metal plate. While ensuring the accurate positioning of the sheet metal plate, the generation of debris can also be reduced.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When the present invention is in use, the extended end of the cylinder is controlled to extend to the longest length. During this process, the baffle cooperates with the first tension spring to drive the sliding plate to move. After the sliding plate contacts the lower die seat, the extended end of the cylinder continues to extend, and the roller provides a rolling thrust to the L-shaped flip rod, so that the L-shaped flip rod flips, and the electric heating ring fits the sheet metal plate on the lower die seat. The electric heating ring is turned on to heat the part of the sheet metal plate that needs to be stamped, thereby reducing the probability of wrinkles during the stamping process.

[0019] When the present invention is in use, the extended end of the hydraulic cylinder is controlled to shrink to the shortest, and the output end of the first air outlet pipe is directed toward the punching head. At this time, the lifting frame drives the transmission wheel to move upward, so that the flip plate rotates, and the lifting rod and the piston are pulled to slide downward, and the input end of the second air outlet pipe is blocked by the piston. The hot air blower is turned on, and the generated hot air flow is injected into the adjusting cylinder through the air inlet pipe, and then sprayed along the first air outlet pipe to heat the bottom of the punching head. When the extended end of the hydraulic cylinder reaches the set length, the bottom of the punching head is immersed in the grinding oil in the storage tank, and the grinding oil will adhere to the bottom of the punching head. Due to the high temperature of the punching head, the viscosity of the grinding oil on its surface is reduced, so as to avoid excessive grinding oil adhering to the bottom of the punching head. When punching the sheet metal plate, the grinding oil is prevented from directly flushing the sheet metal plate. While ensuring the accurate positioning of the sheet metal plate, the generation of debris can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] See also Figure 1-Figure 6 As shown, the above-mentioned regulating unit 27 includes a flip plate 274 rotatably connected to the fixed frame 9, a lifting rod 272 is arranged on one side of the flip plate 274, the bottom of the lifting rod 272 is movably connected to the flip plate 274 through a lever 273, and the top end of the lifting rod 272 movably penetrates into the regulating cylinder 21 and is fixedly installed with a piston 271.

[0038] See also Figure 4 As shown, a third tension spring 22 is fixedly connected between the piston 271 and the top of the inner wall of the adjusting cylinder 21; by controlling the extended end of the hydraulic cylinder 10 to shrink to the shortest, the output end of the first air outlet pipe 23 faces the punching head 11, at this time, the lifting frame 8 drives the transmission wheel 275 to move upward, so that the flip plate 274 rotates, pulls the lifting rod 272 and the piston 271 to slide downward, and blocks the input end of the second air outlet pipe 26 through the piston 271, turns on the hot air blower 1, and the generated hot air flow is injected into the adjusting cylinder 21 through the air inlet pipe 28. , and then sprayed out along the first air outlet pipe 23 to heat the bottom of the punch head 11. When the extended end of the hydraulic cylinder 10 reaches the set length, the bottom of the punch head 11 is immersed in the grinding oil in the storage tank 41, and the grinding oil will adhere to the bottom of the punch head 11. Due to the high temperature of the punch head 11, the viscosity of the grinding oil on its surface is reduced, avoiding excessive grinding oil from adhering to the bottom of the punch head 11. When stamping the sheet metal plate, the grinding oil is prevented from directly scouring the sheet metal plate, which can ensure the accurate positioning of the sheet metal plate and reduce the generation of debris.

[0039] See also Figure 1-Figure 6 As shown, a hydraulic cylinder 10 is fixedly inserted on the above-mentioned fixed frame 9, the hydraulic cylinder 10 is longitudinally arranged, and a lifting frame 8 is fixedly installed on its protruding end, the bottom of the lifting frame 8 is fixedly connected to the punch head 11, and a transmission wheel 275 is rotatably arranged at the end of the lifting frame 8 close to the adjusting cylinder 21, and the transmission wheel 275 is rollingly connected to the end of the flip plate 274 away from the lifting rod 272.

[0040] See also Figure 1 As shown, four guide rods are fixedly connected between the fixing frame 9 and the base 3 , and the middle parts of the four guide rods are movably passed through the lifting frame 8 .

[0041] See also Figure 1As shown, a first guide plate 6 and a second guide plate 7 for guiding the sheet metal plate are provided on a side of the lower die base 5 away from the protection mechanism 4 , and the first guide plate 6 and the second guide plate 7 are both fixedly connected to the base 3 .

[0042] Working principle: When the present invention is used, first, Figure 1 and Figure 2 As shown, one end of the sheet metal plate is placed on the lower die base 5 by an external loading device, and the sheet metal plate is located between the first guide plate 6 and the second guide plate 7. The first guide plate 6 and the second guide plate 7 cooperate with each other to limit the sheet metal plate to prevent it from shifting. At this time, the extended end of the cylinder 44 is in the shortest state; Figure 1 , Figure 4 and Figure 5 As shown, by controlling the extended end of the hydraulic cylinder 10 to contract to the shortest, the output end of the first air outlet pipe 23 faces the punch head 11. At this time, the lifting frame 8 drives the transmission wheel 275 to move upward, so that the flip plate 274 rotates, pulls the lifting rod 272 and the piston 271 to slide downward, and blocks the input end of the second air outlet pipe 26 through the piston 271. The hot air blower 1 is turned on, and the generated hot air flow is injected into the adjustment cylinder 21 through the air inlet pipe 28, and then ejected along the first air outlet pipe 23 to heat the bottom of the punch head 11; Figure 1 and Figure 2 As shown, the extended end of the control cylinder 44 is extended to the longest. During this process, the baffle cooperates with the first tension spring 43 to drive the sliding plate 46 to move. After the sliding plate 46 contacts the lower die seat 5, as shown in FIG. Figure 1-Figure 3 As shown, the extended end of the cylinder 44 continues to extend, and the roller 42 provides a rolling thrust to the L-shaped flip rod 471, so that the L-shaped flip rod 471 flips, and the electric heating ring 472 fits the sheet metal plate on the lower die base 5. The electric heating ring 472 is turned on to heat the part of the sheet metal plate that needs to be stamped, thereby reducing the probability of wrinkles during the stamping process. At the same time, the punch head 11 is located directly above the storage tank 41, and the distance between the output end of the hose 24 and the punch head 11 becomes smaller; Figure 1 , Figure 4 and Figure 5 As shown, by controlling the extended end of the hydraulic cylinder 10 to extend to a set length, due to the tension of the third tension spring 22, the piston 271 is located between the output end of the intake pipe 28 and the input end of the first outlet pipe 23, and the hot air flow is ejected along the second outlet pipe 26 to preheat the sheet metal plate to be stamped later, so as to avoid the temperature rising too fast to affect the product quality of the automobile instrument panel. At the same time, Figure 1 , Figure 2 and Figure 6As shown, when the extended end of the hydraulic cylinder 10 reaches the set length, the bottom of the punch head 11 is immersed in the grinding oil in the storage tank 41, and the grinding oil will adhere to the bottom of the punch head 11. Since the temperature of the punch head 11 is relatively high, the viscosity of the grinding oil on its surface is reduced, thereby preventing excessive grinding oil from adhering to the bottom of the punch head 11. When punching the sheet metal plate, the grinding oil is prevented from directly flushing the sheet metal plate, thereby ensuring accurate positioning of the sheet metal plate and reducing the generation of debris.
