Description

Technical Field

[0001] This invention relates to the field of fin stamping equipment technology, and specifically to a stamping forming equipment for multi-specification fins. Background Technology

[0002] In the process of fin stamping, in order to ensure good lubrication between the workpiece and the die, reduce friction and wear, and improve stamping quality, it is usually necessary to spray oil on the surface of the sheet metal or die before stamping. At present, some stamping equipment adopts a controllable oil spraying system, which can spray lubricating oil in a quantitative manner according to preset parameters. Theoretically, it achieves precise control of the amount of oil sprayed, avoiding the problems of uneven oil application or excessive oil use by manual application.

[0003] The above-mentioned oil spraying lubrication method still has some shortcomings in practical applications: First, the lubricating oil itself has strong volatility, especially in the airflow environment generated by high-speed stamping. The oil droplets sprayed onto the workpiece surface evaporate and diffuse rapidly, making it difficult for the oil film to adhere stably and evenly to the workpiece surface, thus weakening the continuity and reliability of the lubrication effect. Second, existing oil spraying systems usually adopt an overall or regional spraying method, where the lubricating oil is sprayed over a large area rather than precisely applied to the stamping parts that actually participate in deformation (such as convex, flanging, punching, etc.), resulting in a large amount of lubricating oil failing to play an effective lubricating role, forming ineffective spraying, and increasing the cost of oil. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a stamping forming equipment for multi-specification fins, which can effectively solve the problems of oil film being difficult to adhere stably and uniformly to the workpiece surface and the inability to achieve effective spraying lubrication in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a stamping forming equipment for multi-specification fins, including an upper die and a lower die, and also includes an auxiliary component. The auxiliary component includes an auxiliary pressure plate elastically installed at the bottom of the upper die, which is used to press the workpiece before the stamping process when the upper die and the lower die are closed to reduce stamping deformation. The auxiliary pressure plate is provided with a clearance hole corresponding to the die core. The automatic oil-drip component and the automatic air-jet component are distributed sequentially from the feeding end to the upper mold. The automatic oil-drip component includes an oil-drip head that is movably mounted on the auxiliary pressure plate for pressing and dripping oil. The automatic air-jet component includes an air guide component that is mounted on the auxiliary pressure plate, and an air-jet head that is movably mounted at the bottom of the air guide component for pressing and blowing air. In the initial state, both the air-jet head and the oil-drip head extend out of the auxiliary pressure plate and toward the workpiece.

[0006] Furthermore, the air guide component and the auxiliary pressure plate are detachably installed, and the number of air jets on the air guide component is multiple sets. The number of air jets corresponds to the number of transverse mold cores on the upper mold. The bottom of the air jet is provided with a range groove, which is used to limit the diffusion range of lubricating oil.

[0007] Furthermore, the bottom of the oil dripping head is provided with a hemispherical groove, and the oil dripping hole is located at the deepest part of the hemispherical groove. The auxiliary pressure plate is provided with an oil storage component that communicates with the oil dripping hole.

[0008] Furthermore, the automatic oil dripping device also includes a guide sleeve disposed within the auxiliary pressure plate, and the guide sleeve is provided with interconnected inclined grooves and vertical grooves, each of which is provided in two sets, and the oil dripping head is provided with a guide post.

[0009] Furthermore, the guide sleeve is elastically fitted with a movable limiting block to restrict the unidirectional cyclic movement of the guide post within the inclined and vertical grooves.

[0010] Furthermore, a rotating sleeve is rotatably mounted on the auxiliary pressure plate, and a telescopic component is provided at the top of the oil dripping head that is slidably connected to the rotating sleeve. The telescopic component is provided with a limiting strip to prevent relative rotation with the rotating sleeve, and springs are respectively fitted on the telescopic component to abut against the auxiliary pressure plate and the oil dripping head.

[0011] Furthermore, it also includes a frequency-fixing component, which includes a piston cylinder mounted on the auxiliary pressure plate and a telescopic bar elastically mounted on the auxiliary pressure plate and drivenly connected to the piston cylinder. The frequency-fixing component also includes a gear mounted on the auxiliary pressure plate and a turntable mounted on the rotating sleeve. The gear is coaxially mounted with a half gear for actuating the telescopic bar.

[0012] Furthermore, the turntable is provided with a single tooth that can mesh with the gear, and the gear is a unidirectional rotating component.

[0013] Furthermore, the auxiliary pressure plate is composed of two plates, and an oil guide groove is provided on the side of the two plates that are close to each other. An oil guide ring communicating with the oil guide groove is provided on the clearance hole.

[0014] Furthermore, the oil guide ring is provided with multiple sets of overflow grooves arranged in a ring array. Beneficial effects

[0015] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By using the elastic connection between the auxiliary pressure plate and the upper die, the workpiece sheet is fully pressed against the upper die core of the lower die before stamping, which can reduce the plastic deformation caused by uneven force on the thin sheet. The oil is squeezed by the jet nozzle and the jet is combined with the jet to increase the oil application range. Under the restriction of the range groove, the oil is not easy to evaporate into the workshop during the application process. The oil film can be stably and evenly attached to the surface of the workpiece, which improves the continuity and reliability of the lubrication effect. Second, by using the drip head and the telescopic component to spray oil locally, the lubricating oil is sprayed on a small area, namely the part to be stamped. This not only applies the oil precisely to the stamping part that is actually involved in the deformation, but also effectively sprays the oil and reduces the cost of oil. 3. By reciprocating the extension and retraction of the oil dripping head, in conjunction with the guide sleeve and rotating sleeve, the turntable is rotated periodically, causing the gear and half gear to rotate, compressing and storing energy in the telescopic strip, while simultaneously drawing lubricating oil into the piston oil cylinder. As the half gear disengages from the telescopic strip, the telescopic strip resets and squeezes the piston oil cylinder to force its internal lubricating oil into the oil guide groove, thus achieving the periodic application of lubricating oil to the mold core on the upper mold. This solves the shadow effect caused by the mutual shading due to the complex structure of the core mold, and applies oil mist or oil droplets to the surface of the complex-shaped workpiece or mold core, reducing problems such as localized scratches, chip accumulation, or even premature mold failure. The overall spraying uniformity is good. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] See attached document Figure 1-6 A stamping forming device for multi-specification fins includes an upper die 1 and a lower die 2, both of which are equipped with detachable die cores, and further includes: The auxiliary component 3 for assisting fin stamping includes an auxiliary pressure plate 31 elastically mounted at the bottom of the upper die 1. The auxiliary pressure plate 31 is movably mounted below the upper die 1 via a columnar component, and an elastic component is provided between the auxiliary pressure plate 31 and the upper die 1 to press the workpiece before the stamping process when the upper die 1 and the lower die 2 are closed, thereby reducing stamping deformation. When the upper die 1 descends and the lower die 2 is closed for stamping, the auxiliary pressure plate 31 will descend first and press against the workpiece sheet until the workpiece can no longer descend. Since the auxiliary pressure plate 31 is provided with a relief hole 3101 corresponding to the die core, the die core on the upper die 1 will pass through the relief hole 3101 and cooperate with the lower die 2 to punch the workpiece sheet. Since the auxiliary pressure plate 31 will squeeze the workpiece sheet to fully fit with the lower die 2 before stamping, it can reduce the plastic deformation caused by uneven force on the thin plate, prevent the workpiece from warping, and improve stamping accuracy. The automatic oil-drip component 33 and automatic air-jet component 32 are sequentially distributed from the feeding end to the upper mold 1. When the workpiece plate enters the upper mold 1 and the lower mold 2, it will first pass through the automatic oil-drip component 33 and then through the automatic air-jet component 32. The automatic oil-drip component 33 includes an oil-drip head 332 movably mounted on the auxiliary pressure plate 31 for pressing and dripping oil. Pressing and opening is existing technology, and there are many existing methods that can achieve this, so it will not be described in detail here. The bottom of the oil-drip head 332 is provided with a hemispherical groove, and the oil-drip hole is located at the deepest part of the hemispherical groove. By providing a hemispherical groove at the bottom of the oil-drip head 332, the lubricating oil is prevented from dripping onto the workpiece plate and sticking to the oil-drip head 332. The auxiliary pressure plate 31 is provided with an oil storage component 331 that communicates with the oil-drip hole. The oil storage component 331 is connected to an external oil storage device to continuously supply oil to the oil-drip head 332. The automatic air-jet component 32 includes an air guide component 321 mounted on the auxiliary pressure plate 31. The auxiliary pressure plate 31 is detachably installed, and the bottom of the air guide 321 is movably installed with a jet head 322 for pressing and blowing air. Pressing and opening is existing technology, and there are many means in the existing technology that can achieve this, so it will not be described in detail here. There are multiple sets of jet heads 322 on the air guide 321, and the number of jet heads 322 corresponds to the number of transverse mold cores on the upper mold 1. The bottom of the jet head 322 is provided with a range groove 3221, which is used to limit the diffusion range of lubricating oil. While ensuring the distribution range of lubricating oil, it prevents the lubricating oil from being atomized and evaporated by high-speed gas. In the initial state, both the jet head 322 and the oil drip head 332 extend out of the auxiliary pressure plate 31 and extend towards the workpiece. When the auxiliary pressure plate 31 descends, the jet head 322 and the oil drip head 332 will contact the workpiece plate first, and then press and open as the auxiliary pressure plate 31 descends to prevent the lubricating oil from being blown into the operating room by high-speed gas and evaporating quickly.

[0022] Specifically, the automatic oil-drip component 33 also includes a guide sleeve 333 disposed within the auxiliary pressure plate 31. The guide sleeve 333 contains interconnected inclined grooves 3331 and vertical grooves 3332. Both inclined grooves 3331 and vertical grooves 3332 are provided in two sets. The oil-drip head 332 is equipped with a guide post 3322. The upper and lower ends of the inclined groove 3331 are respectively connected to the upper and lower ends of the movable limiting block 3333. Similarly, the upper and lower ends of the vertical groove 3332 are respectively connected to the upper and lower ends of the adjacent inclined groove 3331. This allows the oil-drip head 332 to undergo vertical displacement with the guide sleeve 333, and when the oil-drip head 332 moves upward, it is compressed and retracted from the workpiece plate. The guide post 3322 will rise along the vertical groove 3332 without rotating. When the upper mold 1 and the lower mold 2 are separated, that is, when the drip head 332 extends out of the guide sleeve 333, the guide post 3322 enters the inclined groove 3331 and guides the drip head 332 to rotate 180°. Since the guide sleeve 333 is elastically installed with a movable limit block 3333, when the guide post 3322 moves upward, it will squeeze the movable limit block 3333 to retract. When the guide post 3322 exceeds the movable limit block 3333, it extends out, thereby guiding the guide post 3322 into the inclined groove 3331, thereby realizing the unidirectional movement of the guide post 3322 in the circulation groove composed of the inclined groove 3331 and the vertical groove 3332.

[0023] Furthermore, a rotating sleeve 3323 is rotatably mounted on the auxiliary pressure plate 31. The top of the drip head 332 is provided with a telescopic component 3321 that is slidably connected to the rotating sleeve 3323. The telescopic component 3321 is provided with a limiting strip to prevent relative rotation with the rotating sleeve 3323. Springs are sleeved on the telescopic component 3321 to abut against the auxiliary pressure plate 31 and the drip head 332 respectively. With the cooperation of the telescopic component 3321 and the rotating sleeve 3323, the rotating sleeve 3323 will rotate 180° each time the drip head 332 rises. The oil storage component 331 is connected to the rotating sleeve 3323 through a rotary joint. That is, when the rotating sleeve 3323 rotates, it can prevent the oil supply pipe on the oil storage component 331 from getting tangled under the action of the rotary joint. In addition, the telescopic component 3321 and the rotary joint on the rotating sleeve 3323 are connected by a telescopic tube to ensure that the telescopic component 3321 can still supply oil to the drip head 332 when it is displaced in the vertical direction.

[0024] In the above technical solution, firstly, through the elastic connection between the auxiliary pressure plate 31 and the upper mold 1, the workpiece sheet is fully attached to the upper mold core of the lower mold 2 before stamping, while pressing the stamping side of the workpiece sheet. This can reduce the plastic deformation caused by uneven force on the thin sheet. Then, the jet nozzle 322 squeezes the oil and, together with the jet nozzle 322, increases the lubricating oil application range. Under the restriction of the range groove 3221, the lubricating oil is not easy to evaporate into the workshop during the application process. The oil film can be stably and evenly attached to the workpiece surface, improving the continuity and reliability of the lubrication effect. On the other hand, after adopting local spraying, the lubricating oil is sprayed in a smaller area, that is, the part to be stamped. This not only applies precisely to the stamping part that actually participates in the deformation, but also effectively sprays and reduces the oil cost.

[0025] See attached document Figure 2 and attached Figure 7-8 It is worth noting that the system also includes a frequency-fixing component 4. The frequency-fixing component 4 includes a piston cylinder 45 mounted on the auxiliary pressure plate 31 and a telescopic strip 44 elastically mounted on the auxiliary pressure plate 31 and drivenly connected to the piston cylinder 45. The piston cylinder 45 is provided with an oil inlet pipe, which is connected to an external oil supply device. A one-way valve is provided in the oil inlet pipe for the oil supply device to deliver lubricating oil into the piston cylinder 45 in one direction. The frequency-fixing component 4 also includes a gear 42 mounted on the auxiliary pressure plate 31 and a turntable 41 mounted on the rotating sleeve 3323. The turntable 41 is provided with a single tooth that can mesh with the gear 42. Furthermore, gear 42 is a unidirectional rotating component. The unidirectional rotation of gear 42 can be achieved by many existing structures, such as ratchet or ratchet teeth. As long as the unidirectional rotation of gear 42 can be achieved, there is no limitation here. Gear 42 is coaxially mounted with a half gear 43 for actuating the telescopic bar 44. The telescopic bar 44 has multiple teeth on the side near the half gear 43. As the half gear 43 rotates, it actuates the telescopic bar 44 to move and cooperate with the piston oil cylinder 45 to draw lubricating oil. As the half gear 43 disengages from the teeth on the telescopic bar 44, the telescopic bar 44 resets and squeezes out the lubricating oil in the piston oil cylinder 45.

[0026] In addition, the auxiliary pressure plate 31 consists of two plates, and an oil guide groove 3102 is provided on the side of the two plates that are close to each other. The oil outlet end of the piston cylinder 45 is connected to the oil guide groove 3102. By setting an oil pipe with a one-way valve in the oil outlet end of the piston cylinder 45, lubricating oil is unidirectionally transported from the piston cylinder 45 to the oil guide groove 3102. Therefore, when the piston cylinder 45 is pumping oil, the lubricating oil in the oil guide groove 3102 in the auxiliary pressure plate 31 will not be sucked back, thereby improving the oil delivery efficiency. To ensure oil stability, an oil guide ring 3103 is provided on the relief hole 3101, which is connected to the oil guide groove 3102. The oil guide ring 3103 is provided with multiple sets of overflow grooves 3104 arranged in a ring array. The number of overflow grooves 3104 is not limited, but the number is greater than or equal to four sets. With the cooperation of the oil guide ring 3103 and the overflow grooves 3104, the lubricating oil squeezed out from the oil guide groove 3102 is evenly squeezed into the relief hole 3101 and coated onto the mold core of the upper mold 1.

[0027] In the above technical solution, the reciprocating extension and retraction of the oil drip head 332 cooperates with the guide sleeve 333 to periodically rotate the rotating sleeve 3323. At this time, the turntable 41 set on the rotating sleeve 3323 will drive the gear 42 to rotate, which in turn drives the half gear 43 to rotate. Due to the number of teeth of the turntable 41 and the half gear 43, when the turntable 41 rotates once, the gear 42 rotates by one tooth angle, which cooperates with the half gear 43 to compress and store energy for the telescopic strip 44. At the same time, it creates a negative pressure in the piston oil cylinder 45 to draw out lubricating oil. After the half gear 43 separates from the telescopic strip 44, the telescopic strip 44 resets and squeezes the piston oil cylinder 45 to squeeze the lubricating oil inside into the oil guide groove 3102. This achieves the periodic application of lubricating oil to the mold core on the upper mold 1, which solves the shadow effect caused by mutual occlusion due to the complex structure of the core mold. The oil mist or oil droplets are placed on the surface of the complex-shaped workpiece or mold core, reducing the problems of local scratches, chip accumulation, or even early mold failure. The overall spraying uniformity is good.

[0028] Working principle: When the upper die 1 and lower die 2 are closed, due to the elastic connection between the auxiliary pressure plate 31 and the upper die 1, the workpiece plate is fully pressed against the upper die core of the lower die 2 before stamping, while pressing the stamping side of the workpiece plate. At the same time, the jet nozzle 322 squeezes oil onto the workpiece plate to be stamped. With the jetting of the jet nozzle 322 in the next station, the oil-spraying area is spread to the disc area, increasing the coverage of lubricating oil. When the oil drip nozzle 332 sprays, under the restriction of the range groove 3221, the lubricating oil is not easy to evaporate into the workshop during the application process, thus reproducing the precise spraying or covering of lubricating oil before stamping. During the reciprocating extension and retraction of the oil drip nozzle 332, it works with the guide sleeve 333 to rotate the sleeve 3. 323 rotates periodically, driving the turntable 41 on the rotating sleeve 3323 to rotate the gear 42 by a certain angle. When the gear 42 rotates once, the half gear 43 on the gear 42 will push the telescopic bar 44 to make linear motion while compressing and storing energy. The telescopic bar 44 pulls the piston in the piston oil cylinder 45 to create negative pressure to draw out lubricating oil. After the half gear 43 is separated from the telescopic bar 44, the telescopic bar 44 resets and squeezes the piston oil cylinder 45 to squeeze the lubricating oil inside into the oil guide groove 3102. In conjunction with the oil guide ring 3103 and the overflow groove 3104, lubricating oil is added to the mold core passing through the relief hole 3101, so as to achieve periodic application of lubricating oil to the mold core.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
