Description

Technical Field

[0001] The present invention relates to the technical field of full-automatic stamping for automobile parts processing, in particular to a full-automatic stamping device for automobile parts processing. Background Art

[0002] Fully automated stamping technology is essential for reducing the cost of metal parts stamping. A fully automated stamping line is a large, three-dimensional, integrated production line that effectively improves the quality of metal parts processing and enables full automation of the entire process. This improves processing efficiency, reduces the demand for raw materials, and lowers worker workload, significantly increasing manufacturers' profits from metal parts production.

[0003] Existing fully automatic stamping devices for automobile parts processing are usually composed of three parts: a stamping part, a loading part, and a unloading part. Since the sheet metal parts of automobile parts are relatively complex, when it comes to stamping decorative parts, for example, in order to improve the grip, high-end automobile gear levers usually use smaller metal stamping parts to enhance the texture. Conventional fully automatic stamping equipment has large structural limitations when stamping smaller parts, and switches back and forth between the three assembly parts, with a slow operating speed, which easily leads to low efficiency. Secondly, since conventional stamping equipment adopts a vertical stamping layout, suction cups are used for loading and unloading, which leads to low equipment operation efficiency, and for smaller parts, it is easy to cause inconvenience in unloading. Summary of the Invention

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a fully automatic stamping device for automobile parts processing, comprising two fixed plates arranged in parallel one above and one below, with vertical shafts fixed vertically at both ends of the two fixed plates, two bracket plates rotatably provided on each of the vertical shafts, a polygonal plate fixedly provided on the outer ends of the two bracket plates, the polygonal plate is coaxially arranged with the vertical shaft, a plurality of mold plates are arranged in a circular array along the axis of the polygonal plate, the mold plate is located on the vertical plane of the polygonal plate, and synchronous gears are provided on the upper ends of the two polygonal plates, the two synchronous gears are meshed with each other, and one of the synchronous gears is transmission-connected to an existing power device.

The pushing mechanism can drive the mold plate to move radially along the axis of the polygonal plate. The pushing mechanism includes multiple cross bars, and the cross bars are fixedly arranged at the center of the rear end of the mold plate. The ends of the cross bars away from the mold plate are rotatably connected to two angle bars, and the ends of the two angle bars away from the cross bars are rotatably connected to vertical bars. The angle bars and the vertical bars are rotatably connected by torsion spring hinges, and the two vertical bars are respectively vertically slidingly arranged on the bracket plate, and the ends of the two vertical bars away from the angle bars are provided with pressure devices for driving the vertical bars to slide vertically.

[0007] As a further solution of the present invention, the pressure device includes a pressure ring plate, which is coaxially fixed to the vertical shaft. The lower end surface of the pressure ring plate is provided with a flat surface and a convex surface. The two convex surfaces are located near the lower end of the pressure ring plate, and a smooth surface is provided between the convex surface and the flat surface. The vertical rod is provided on the side wall of the pressure ring plate.

[0008] As a further solution of the present invention, one end of the vertical rod away from the angle rod is rotatably connected to a roller, and the roller rolls and contacts the convex surface, the flat surface and the smooth surface.

[0009] As a further solution of the present invention, two bite ring plates are fixedly provided on the side wall of each polygonal plate, one above and one below.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention drives two polygonal plates to reverse synchronously through two mutually meshing synchronous gears, thereby driving multiple mold plates to revolve, and the left and right mold plates are meshed and separated, so that the raw materials passing between the two mold plates are pressed, thereby forming a shape stamping, and with the continuous revolution, meshing and separation of the multiple mold plates, the strip-shaped raw materials are continuously pressed, and due to the use of vertical pressing, the mold plate with a cutting line can complete the cutting, so that automatic unloading can be performed, thereby effectively improving the stamping efficiency.

[0015] 2. The present invention drives the two vertical rods to move closer to each other through a pressure device, thereby overcoming the force of the torsion spring hinge and driving the angle rod to rotate, so that the mold plates that are revolving close to each other are further moved closer and engaged, thereby completing the stamping, avoiding the problem of the radius of the polygonal plate between the conventional mold plates that directly revolve and engage, which makes the demoulding angle of the parts too large, making it impossible to perform deep stamping in a small range on the parts, resulting in greater equipment limitations. Secondly, it also avoids the problem that when stamping between conventional mold plates that revolve and engage, the equipment is easily damaged by large vibration.

DETAILED DESCRIPTION

[0023] 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 any creative efforts shall fall within the scope of protection of the present invention.

[0024] See also Figures 1-4 The present invention provides a technical solution: a fully automatic stamping device for automobile parts processing, comprising two fixed plates 10 arranged in parallel, one above and one below, with vertical shafts 11 respectively fixedly arranged at both ends of the two fixed plates 10, two bracket plates 12 rotatably arranged on each vertical shaft 11, a polygonal plate 13 fixedly arranged at the outer ends of the two bracket plates 12, the polygonal plate 13 and the vertical shaft 11 are coaxially arranged, and a plurality of mold plates 14 are arranged in a circular array along the axis of the polygonal plate 13, the mold plate 14 is located on the vertical plane of the polygonal plate 13, and a synchronous gear 15 is provided on the upper end of the two polygonal plates 13, the two synchronous gears 15 are meshed with each other, and one of the synchronous gears 15 is transmission-connected to an existing power device;

[0025] Before using the present invention, the device is assembled and the fixing plate 10 is fixed to the outside world. Figure 1 As shown, the device is set up in a left-right symmetrical manner. Figure 1 Looking down from above is the upper end of the device, wherein the feeding end is the front end. The device itself does not have a power device and needs to cooperate with the existing power device to work. The device is used for stamping decorative parts of automotive parts. Under the trend of lightweighting, as the thickness of the decorative parts themselves is relatively small, the feeding can be carried out in a roller-winding manner so that the metal raw material is formed into a strip and transported to the equipment. The left and right mold plates 14 are mutually matched male and female molds. Since the device uses multiple mold plates for cyclic stamping, when the decorative parts required for the production of vehicles are different, different molds can also be used to load different decorative parts of the device to produce different decorative parts (the decorative parts of the same vehicle are relatively fixed, and the production efficiency of the device is relatively fast, and the problem of overcapacity is very likely to occur, but decorative parts suitable for multiple vehicles can be produced at the same time. On the one hand, there is no need to change the mold many times, and on the other hand, the overall production capacity uniformity can be improved, thereby improving the utilization rate of the equipment and avoiding waste);

[0026] When the device is used, the existing power device drives the synchronous gear 15 to rotate, and the synchronous gear 15 rotates to drive the polygonal plate 13 to rotate (such as Figure 1As shown, the polygonal plate 13 is rotatably arranged on the vertical shaft 11 through the bracket plate 12, and the bracket plate 12 rotates on the vertical shaft 11, thereby limiting the axial position of the polygonal plate 13, so that the polygonal plate 13 can only rotate around its own axis, that is, the axis of the vertical shaft 11). The two synchronous gears 15 are engaged with each other (so that the left and right mold plates 14 rotate synchronously to avoid transmission difference, resulting in abnormal engagement between the mold plates 14, causing damage to the mold plates 14, and even causing damage to the equipment). As a result, the polygonal plates 13 on both sides rotate synchronously and oppositely, and the polygonal plates 13 rotate When the left and right mold plates 14 are engaged, the mold plates 14 are driven to rotate synchronously. The mold plates 14 revolve, and the strip raw materials are input vertically into the equipment to keep the raw materials moving. When the left and right mold plates 14 revolve and engage, the raw material plate passing through the center is squeezed, causing the raw materials to deform, thereby completing the stamping process. After the two mold plates 14 are engaged, the mold plates 14 themselves have cutting strips, which can cut out the stamped parts, thereby separating the parts from the strip raw materials. The vertical input of the raw materials completes the automatic unloading, thereby improving the efficiency of the equipment.

[0027] The present invention drives two polygonal plates 13 to rotate synchronously through two mutually meshing synchronous gears 15, thereby driving multiple mold plates 14 to revolve, and the left and right mold plates 14 are meshed and separated, so that the raw materials passing between the two mold plates 14 are pressed, thereby forming a shape stamping, and with the continuous revolution, meshing and separation of the multiple mold plates 14, the strip-shaped raw materials are continuously pressed, and because vertical pressing is adopted, the mold plate 14 can complete cutting with a cutting line, so that automatic unloading can be performed, thereby effectively improving the stamping efficiency.

[0028] As a further solution of the present invention, a pushing mechanism is provided at the rear end of the mold plate 14. The mold plate 14 is laterally slidingly arranged on the side wall of the polygonal plate 13. The pushing mechanism can drive the mold plate 14 to move radially along the axis of the polygonal plate 13. The pushing mechanism includes a plurality of cross bars 17. The cross bars 17 are fixedly arranged at the center of the rear end of the mold plate 14. The ends of the cross bars 17 away from the mold plate 14 are rotatably connected to two angle bars 18. The ends of the two angle bars 18 away from the cross bars 17 are rotatably connected to vertical bars 19. The angle bars 18 and the vertical bars 19 are rotatably connected by torsion spring hinges 20. The two vertical bars 19 are respectively vertically slidingly arranged on the bracket plate 12. The ends of the two vertical bars 19 away from the angle bars 18 are provided with a pressure device for driving the vertical bars 19 to slide vertically.

[0029] When using this device, Figure 2 and 3As shown, due to the different shapes of the decorative stamping parts themselves, when the surface difference of the parts is large, the two mold plates 14 directly adopt rolling meshing, which is very likely to cause interference and abnormal bite problems. Therefore, it is necessary to expand the diameter of the polygonal plate 13 to solve the above problem, that is, the demoulding angle of the mold plate 14 is large. However, due to the space limitation of the factory, the polygonal plate 13 cannot be infinitely enlarged, so it is necessary to effectively solve the problem by bringing the mold plates 14 closer to each other. When the two mold plates 14 are close to each other, the pressure device starts to drive the vertical rod 19 to move toward the central horizontal plane of the polygonal plate 13, and the vertical rod 19 moves Drive the angle rod 18 down. Since the end of the angle rod 18 away from the vertical rod 19 is rotated and arranged on the horizontal rod 17 which can only move horizontally, the end of the angle rod 18 away from the horizontal rod 17 and the vertical rod 19 rotate, so that the obtuse angle between the angle rod 18 and the vertical rod 19 is reduced. The angle rod 18 and the vertical rod 19 overcome the force of the torsion spring hinge 20 and rotate relative to each other, so that the angle rod 18 tends to rotate in the horizontal direction. Since the end of the angle rod 18 away from the horizontal rod 17 is affected by the vertical rod 19 and can only move vertically, the rotating part of the angle rod 18 and the horizontal rod 17 moves horizontally. The cross bar 17 is pushed to move radially along the axis of the polygonal plate 13 (the mold plate 14 moves radially along the axis of the polygonal plate 13), and the cross bar 17 moves to drive the mold plate 14 to move outward. When the two mold plates 14 approach each other, the cross bar 17 pushes the two mold plates 14 to engage, thereby completing the stamping of the strip-shaped raw material (the two vertical rods 19 and the angle rod 18 make the equipment force more uniform and reasonable, avoiding abnormal wear or even jamming of the equipment), and because the rotation of the angle rod 18 is affected by the vertical rod 19, the downward movement speed of the vertical rod 19 remains unchanged, so that the angle rod 18 is The horizontal component speed is from fast to slow, so that the speed of the two mold plates 14 is the smallest at the moment of combination, avoiding the mold plates 14 from colliding, causing large vibration of the equipment, vibration of the raw materials, and abnormal stretching of the stamping. Secondly, it also avoids the mold plates 14 from closing too quickly, and the raw materials have no time to deform and stretch, resulting in product breakage or stretching scars on the parts. After the stamping of the mold plate 14 is completed, the pressure device unloads the power, so that the torsion spring hinge 20 acts to increase the obtuse angle between the angle rod 18 and the vertical rod 19, thereby separating the two mold plates 14 and completing the stamping process;

[0030] The present invention drives the two vertical rods 19 to move closer to each other through a pressure device, thereby overcoming the force of the torsion spring hinge 20 and driving the angle rod 18 to rotate, so that the mold plates 14 that are revolving close to each other are further moved closer and engaged, thereby completing the stamping, avoiding the problem of the radius of the polygonal plate 13 between the conventional mold plates 14 that directly revolve and engage, resulting in excessively large demoulding angles of parts, making it impossible to perform deep stamping of parts in a small range, resulting in greater equipment limitations. Secondly, it also avoids the problem that when stamping between conventional mold plates 14 that revolve and engage, the equipment is easily shaken, thereby causing damage to the equipment.

[0031] As a further embodiment of the present invention, the pressurizing device includes a pressurizing ring plate 23, which is coaxially fixedly connected to the vertical shaft 11. The lower end surface of the pressurizing ring plate 23 is provided with a flat surface 24 and a convex surface 25. The two convex surfaces 25 are located near the lower end of the pressurizing ring plate 23. A smooth surface 26 is provided between the convex surface 25 and the flat surface 24. The vertical rod 19 is provided on the side wall of the pressurizing ring plate 23; the end of the vertical rod 19 away from the angle rod 18 is rotatably connected to a roller 28, and the roller 28 rolls on the convex surface 25, the flat surface 24 and the smooth surface 26.

[0032] When the present invention is used, Figure 2 As shown, the polygonal plate 13 rotates to drive the bracket plate 12 to rotate, the bracket plate 12 rotates to drive the vertical rod 19 to rotate, and the vertical rod 19 rotates to drive the roller 28 to roll on the convex surface 25, the flat surface 24 and the smooth surface 26. When the two mold plates 14 rotate and approach each other, the roller 28 rolls from the flat surface 24 to the smooth surface 26, so that the two vertical rods 19 approach each other, thereby making the two mold plates 14 closer to each other until the roller 28 rotates to the convex surface 25 and the movement of the vertical rod 19 stops. The two mold plates 14 press the strip-shaped raw materials. When the stamping is completed, the roller 28 rolls from the convex surface 25 to On the smooth surface 26, the two vertical rods 19 begin to move away from each other, thereby separating the two mold plates 14. Through the action of the raised surface 25, the flat surface 24 and the smooth surface 26, the roller 28 moves up and down. On the one hand, it avoids the vertical rods 19 from directly contacting the raised surface 25, the flat surface 24 and the smooth surface 26 to cause abnormal wear. On the other hand, the roller 28 rolls on the raised surface 25, the flat surface 24 and the smooth surface 26, which can effectively reduce the vibration of the equipment, thereby avoiding large vibration of the equipment and vibration of the raw materials, resulting in abnormal stretching of the stamping, resulting in product breakage or stretching scars on the parts.

[0033] As a further solution of the present invention, two bite ring plates 30 are fixedly provided on the side wall of each polygonal plate 13, one above and one below, so that the two bite ring plates 30 at the same height can drive the strip-shaped parts to move, thereby cooperating with the equipment for synchronous stamping, avoiding the asynchronous movement of raw materials during the stamping process, resulting in abnormal stretching during the stamping, causing product breakage or stretching scars on the parts.

[0034] As a further solution of the present invention, a friction-reducing coating is applied on the sliding contact surface between the upright pole 19 and the bracket plate 12 to reduce friction of the equipment and extend the service life of the equipment.

[0035] As a further solution of the present invention, a V-shaped guide plate 31 is provided at the upper end of the fixed plate 10 at the lower end, so that the strip-shaped raw materials can be moved in a directional manner to avoid directional swinging during movement, which may cause abnormal stretching during stamping, resulting in product breakage or stretching scars on parts.

[0036] As a further solution of the present invention, the fixed plate 10 can be telescopically locked, and the fixed plate 10 can be slightly adjusted to enable the equipment to stamp strip-shaped raw materials of different thicknesses, thereby improving the applicability of the equipment. Since the thickness of the stamped sheet metal also fluctuates at the two-digit millimeter level after the decimal point, the change of less than one millimeter in the spacing between the synchronous gears 15 will not affect the transmission ratio of the synchronous gears 15, nor will it affect the life of the synchronous gears 15. Therefore, abnormal wear and jamming of the synchronous gears 15 are not considered.
