Description

Technical Field

[0001] This invention relates to the field of stamping technology, and more particularly to a stamping apparatus for galvanized steel sheets. Background Technology

[0002] Galvanized steel sheet refers to steel sheet with a layer of zinc on its surface. It is a common metal material. Galvanized steel sheet usually uses cold-rolled steel sheet as the base material and a layer of zinc is plated on its surface by hot-dip galvanizing or electro-galvanizing. Galvanized steel sheet stamping forming equipment is a special mechanical equipment designed specifically for the material characteristics of galvanized steel sheet. It is a special mechanical equipment that processes flat galvanized steel sheet into workpieces with specific three-dimensional shapes through stamping process.

[0003] Patent application number CN201810117327.5 describes in its specification that "This invention provides a hot stamping forming device for galvanized steel sheets, including a hot stamping forming machine; the hot stamping forming machine includes a punch press, a mold, a heating component, and a cooling component, the cooling component being disposed within the mold, the mold being disposed on the punch press, the heating component being electrically connected to the workpiece, the hot stamping forming machine further including a heat-absorbing material recovery component and a sealing component, the punch press, mold, heating component, cooling component, and heat-absorbing material recovery component all being disposed within the sealing component; the sealing component includes an inlet sealing door and an outlet sealing door; the heating component uses electric heating, the heating component includes a heating wire and a heating switch; the cooling component includes a circulating cooling passage disposed on the upper and lower molds of the mold. This invention effectively solves the technical problem of brittle fracture of liquid metal in existing hot stamping forming of galvanized steel sheets, and collects and cools the heat-absorbing material through a suction component."

[0004] While existing technologies offer the advantages mentioned above, they also have disadvantages. Galvanized steel sheets, due to the sacrificial protection of the zinc coating, possess excellent corrosion resistance and are widely used in industries such as automobiles, home appliances, and construction. However, during the stamping process, the zinc coating is relatively soft and has limited adhesion, making it prone to problems such as zinc coating sticking to the mold, scratches, and peeling, leading to a decrease in the corrosion resistance of the finished product. Therefore, a galvanized steel sheet stamping device is urgently needed to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art where galvanized steel sheets, due to the sacrificial protection of the zinc layer on the surface, have excellent corrosion resistance and are widely used in industries such as automobiles, home appliances, and construction. However, during the stamping process, because the zinc layer is relatively soft and has limited adhesion, problems such as zinc layer sticking to the mold, scratches, and peeling are prone to occur, leading to a decrease in the corrosion resistance of the finished product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a galvanized steel sheet stamping forming device, comprising: a fixed frame, and further comprising:

[0016] The technical effect of adopting the above-mentioned further solution is that the hydraulic cylinder is fixedly installed on the outer surface of the fixed frame, which facilitates the stability of the hydraulic cylinder during operation. When the hydraulic cylinder is working, it drives the connecting plate 1 and the elastic element 1 to move linearly. When the elastic element 1 moves, it drives the connecting plate 2, the punch, and the die to move linearly. After the die is restricted, the connecting plate 1, the connecting plate 2, and the punch can continue to move, but the elastic element 1 will be compressed. After the punch contacts the plate, it squeezes the plate to deform, so that the plate enters the interior of the die, thereby stamping the plate.

[0027] Two folding blocks are respectively connected to one end of the two push rods, and the outer surfaces of the two folding blocks are mounted on the outer surface of the die.

[0028] Two elastic elements are respectively disposed on the outer surfaces of the two folded blocks, wherein the other ends of the two elastic elements are respectively connected to the outer surfaces of the two mounting cylinders.

[0029] The technical advantages of adopting the above-mentioned further solutions are: the mounting plate is fixedly connected to the concave mold, which facilitates the enhancement of the stability of the mounting plate; the mounting plate is slidably connected to the through hole, which facilitates the improvement of the stability of the mounting plate when moving vertically.

[0030] Preferably, the adaptive component further includes:

[0031] Two sets of positioning blocks are respectively connected to the outer surfaces of the two folding blocks. Each set of positioning blocks has a sliding groove on its outer surface, and the inner walls of the two sets of sliding grooves are respectively set on the outer surfaces of the two folding blocks.

[0032] Two sets of connecting rods are respectively installed on the inner walls of the two sets of sliding grooves, and the outer surfaces of the two sets of connecting rods are respectively connected to the inner walls of the two folding blocks;

[0033] Two sets of elastic elements are respectively disposed on the inner walls of the two sets of sliding grooves, wherein the other ends of the two sets of elastic elements are respectively installed on the outer surfaces of the two folding blocks.

[0034] The technical advantages of adopting the above-mentioned further solution are: the positioning block and the folding block are slidably connected, which facilitates the enhancement of the flexibility of the positioning block when moving on the folding block; the slide groove and the folding block are slidably installed, which facilitates the restriction that the positioning block can only move in a straight line on the folding block.

[0035] Preferably, the folding assembly includes:

[0036] Two sealing rings are respectively fitted onto the other end of the two push rods, wherein the outer surfaces of the two sealing rings are respectively connected to the inner walls of the two mounting cylinders.

[0037] Two connecting pipes are respectively connected to the outer surfaces of the two mounting cylinders one, and the other end of each connecting pipe is provided with a mounting cylinder two, and the connecting pipes are connected to the mounting cylinder one and the mounting cylinder two.

[0038] The technical effect of adopting the above-mentioned further solution is that the sealing ring 1 is fixedly installed with the push rod 1, which facilitates the improvement of the stability of the sealing ring 1 when it moves with the push rod 1.

[0039] Preferably, the folding assembly further includes:

[0040] Two push rods are respectively installed on the inner walls of the two mounting cylinders. Each push rod has a sealing ring connected to one end, and the outer surfaces of the two sealing rings are respectively disposed on the inner walls of the two mounting cylinders.

[0041] Two lifting plates are respectively connected to the other end of the two push rods, and iron rods are installed on the inner wall of both lifting plates.

[0043] Preferably, the folding assembly further includes:

[0044] Two support rods are installed on the outer surface of the fixed frame. Each of the two support rods has a magnet connected to its outer surface. The outer surfaces of the two magnets are set on the outer surface of the fixed frame, and the two magnets cooperate with the two iron rods respectively.

[0045] The technical advantages of adopting the above-mentioned further solutions are: the support rod is fixedly installed with the fixed frame, which facilitates the strengthening of the support rod; the support rod is fixedly connected with magnet one, which facilitates the strengthening of the stability of magnet one.

[0046] Preferably, the folding assembly further includes:

[0047] Two magnets are connected to the two ends of the connecting plate, and each magnet is engaged with one of the two iron rods. The attraction force of the magnets on the iron rods is less than that of the magnets on the iron rods.

[0048] The technical effect of adopting the above-mentioned further solution is that when magnet two, iron rod, and magnet one are on the same axis, magnet one can separate iron rod from magnet two, making it easier for iron rod to re-enter the lifting plate, so that connecting plate one no longer restricts the iron rod and lifting plate from descending under the influence of gravity.

[0049] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0050] 1. When the present invention is used, the punch contacts the plate and squeezes the plate to deform it, so that the plate enters the interior of the die and is stamped into a U-shape. By using the segmented elastic buffer design of elastic element one, elastic element two, and elastic element three, damage to the zinc layer on the surface of the plate is reduced, which is beneficial to improving the quality of the stamped product.

[0051] 2. When using this invention, the operator moves the two folding blocks in opposite directions, causing the positioning block and the push rod to move, so that the push rod retracts into the mounting cylinder and the elastic element retracts. Then, the plate is placed between the two folding blocks. After releasing the two folding blocks, the plate is clamped and fixed by the elastic force of the elastic element. The positioning block then restricts the side plate of the plate, which helps to improve the stability of the plate on the die and improves the stability of subsequent stamping and forming work.

[0052] 3. In use, the oil inside the second mounting cylinder enters the inner wall of the first mounting cylinder through the connecting pipe, thereby pushing the first sealing ring and the first pushing rod to move. This facilitates the relative movement of the two pushing rods, which in turn drives the two folding blocks and the positioning blocks to move relative to each other. This is beneficial for the secondary stamping and forming of the U-shaped plate, so that the plate is stamped into a rectangular shape. When the two positioning blocks are in contact, they interact with each other, causing the elastic element five to be compressed. This facilitates the relative movement of the positioning blocks and the folding blocks, and makes it easier for the outer surfaces of the two folding blocks to contact each other, which helps to improve the product quality of the plate being stamped into a rectangular shape.

[0063] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0064] Example 1, such as Figure 1 - Figure 8 As shown, the present invention provides a technical solution: a galvanized steel sheet stamping forming device, comprising: a fixed frame 1 and a stamping assembly.

[0065] The stamping assembly includes: a hydraulic cylinder 4, the outer surface of which is fixedly mounted on the top of the fixed frame 1, a connecting plate 7 fixedly connected to the output end of the hydraulic cylinder 4, an elastic element 8 fixedly mounted on the outer surface of the connecting plate 7, the hydraulic cylinder 4 being connected to an external hydraulic system, and the hydraulic cylinder 4 driving the connecting plate 7 and the elastic element 8 to move linearly when working.

[0066] It should be noted that the other end of the elastic element 8 is fixedly connected to the connecting plate 9, the outer surface of the connecting plate 9 is fixedly connected to the punch 10, and the outer surface of the fixed frame 1 is vertically slidably mounted with the die 3. When the elastic element 8 moves, it drives the connecting plate 9, the punch 10, and the die 3 to move linearly. After the die 3 is restricted, the connecting plate 7, the connecting plate 9, and the punch 10 can continue to move, but the elastic element 8 will be compressed.

[0067] In addition, multiple limiting rods 5 are fixedly installed on the outer surface of the fixed frame 1. The outer surfaces of the multiple limiting rods 5 are slidably disposed on the inner wall of the die 3. When the die 3 moves linearly, its inner wall slides on the outer surface of the limiting rods 5, which facilitates the restriction of the die 3 and improves the stability of the die 3 when it moves linearly.

[0068] As an example, in this embodiment, a plate 311 is movably provided on the outer surface of the die 3, and two through holes 2 are provided on the outer surface of the fixed frame 1. When the die 3 moves, it drives the plate 311 to move linearly.

[0069] In this embodiment, when the hydraulic cylinder 4 is working, it drives the connecting plate 7 and the elastic element 8 to move linearly. When the elastic element 8 moves, it drives the connecting plate 9, the punch 10, and the die 3 to move linearly. After the die 3 is restricted, the connecting plate 7, the connecting plate 9, and the punch 10 can continue to move, but the elastic element 8 will be compressed. After the punch 10 contacts the plate 311, it squeezes the plate 311 to deform, so that the plate 311 enters the interior of the die 3, thereby stamping the plate 311.

[0070] Example 2, as Figure 1 - Figure 8As shown, the present invention provides a technical solution: a galvanized steel sheet stamping and forming device, comprising: an adaptive component.

[0071] It should be noted that the adaptive component includes: multiple elastic elements 6, one end of each elastic element 6 is fixedly installed on the outer surface of the die 3, the other end of each elastic element 6 is fixedly connected to the outer surface of the fixed frame 1, the inner rings of each elastic element 6 are movably sleeved on the outer surface of each limiting rod 5, the limiting rod 5 can prevent the elastic element 6 from bending when bending, the die 3 moves and drives the elastic element 6 to deform, multiple elastic elements 701 are fixedly connected to the outer surface of the connecting plate 7, the other end of each elastic element 701 is fixedly connected to the outer surface of the connecting plate 9, the connecting plate 7 moves and drives the elastic elements 701 to move linearly;

[0072] As examples, in this embodiment, multiple circular tubes 702 are fixedly installed on the outer surface of the connecting plate 7, and circular rods 703 are slidably installed on the other end of each of the multiple circular tubes 702. The other end of each of the multiple circular rods 703 is fixedly connected to the outer surface of the connecting plate 9. Multiple circular tubes 704 are fixedly installed on the outer surface of the connecting plate 7, and circular rods 705 are slidably installed on the outer surface of each of the multiple circular tubes 704. The other end of each of the multiple circular rods 705 is fixedly disposed on the outer surface of the connecting plate 9. When the connecting plate 9 is restricted to remain stationary while the connecting plate 7 continues to move, the elastic element 701 and the elastic element 8 are compressed and contracted, and the total length of the circular tubes 702, 704, 703, and 705 is shortened.

[0073] In addition, two mounting plates 301 are fixedly provided at both ends of the die cavity 3. Mounting cylinders 302 are fixedly installed on the outer surfaces of the two mounting plates 301. The outer surfaces of the two mounting plates 301 are slidably installed on the inner walls of the two through holes 2. Push rods 313 are slidably connected to the inner walls of the two mounting cylinders 302. When the die cavity 3 moves, it drives the mounting plates 301, mounting cylinders 302 and push rods 313 to move linearly. One end of each push rod 313 is fixedly connected to a folding block 315. The outer surfaces of the two folding blocks 315 are slidably installed on the outer surface of the die cavity 3. Elastic elements 316 are fixedly connected to the outer surfaces of the two folding blocks 315. The other ends of the two elastic elements 316 are fixedly connected to the outer surfaces of the two mounting cylinders 302. The elastic elements 316 push the folding blocks 315 to move linearly on the die cavity 3. When the folding blocks 315 move, they drive the push rods 313 to extend out from the mounting cylinders 302.

[0074] In this configuration, positioning blocks 317 are slidably connected to the outer surfaces of the two folding blocks 315. Sliding grooves 320 are provided on the outer surfaces of the two sets of positioning blocks 317. The inner walls of the two sets of sliding grooves 320 are slidably installed on the outer surfaces of the two folding blocks 315. Two sets of connecting rods 318 are fixedly connected to the inner walls of the two sets of connecting rods 318. The outer surfaces of the two sets of connecting rods 318 are slidably connected to the inner walls of the two folding blocks 315. Elastic elements 319 are fixedly connected to the inner walls of the two sets of sliding grooves 320. The other ends of the two sets of elastic elements 319 are fixedly installed on the outer surfaces of the two folding blocks 315.

[0075] In this embodiment, the two folding blocks 315 are moved in opposite directions, causing the positioning block 317 and the push rod 313 to move, so that the push rod 313 retracts into the mounting cylinder 302, and at the same time the elastic element 316 contracts. Then the plate 311 is placed between the two folding blocks 315. After the two folding blocks 315 are released, the elastic force of the elastic element 316 is used to clamp and fix the plate 311. Then the positioning block 317 is used to restrict the side plate of the plate 311, which helps to improve the stability of the plate 311 on the die 3 and improve the stability of subsequent stamping and forming work.

[0076] Example 3, as Figure 1 - Figure 8 As shown, the present invention provides a technical solution: a galvanized steel sheet stamping and forming device, comprising: a folding assembly.

[0077] The folding assembly includes: two sealing rings 314, the inner rings of which are fixedly sleeved on the other ends of two push rods 313 respectively; the outer surfaces of the two sealing rings 314 are slidably connected to the inner walls of two mounting cylinders 302 respectively; two connecting pipes 303 are fixedly connected to the outer surfaces of the two mounting cylinders 302 respectively; and mounting cylinders 304 are fixedly installed at the other ends of the two connecting pipes 303 respectively. The connecting pipes 303 communicate with the mounting cylinders 302 and 304 respectively. The inner walls of the connecting pipes 303, mounting cylinders 302 and 304 are filled with oil. The sealing rings 314 are designed to prevent oil leakage from the mounting cylinders 302.

[0078] It should be noted that push rods 305 are slidably installed on the inner walls of both mounting cylinders 304. One end of each push rod 305 is fixedly connected to a sealing ring 312. The outer surfaces of the sealing rings 312 are slidably installed on the inner walls of the two mounting cylinders 304. The other end of each push rod 305 is fixedly connected to a lifting plate 306. Iron rods 307 are slidably installed on the inner walls of each lifting plate 306. Under the influence of gravity, the iron rods 307 and the lifting plates 306 will move downward, thereby causing the push rods 305 to extend out of the mounting cylinders 304. The sealing rings 312 can prevent oil from leaking from the mounting cylinders 304.

[0079] In addition, two support rods 308 are fixedly installed on the outer surface of the fixed frame 1. Magnets 309 are fixedly connected to the outer surface of the two support rods 308. The outer surfaces of the two magnets 309 are fixedly installed on the outer surface of the fixed frame 1. The two magnets 309 cooperate with the two iron rods 307 respectively. When the iron rods 307 move with the lifting plate 306 and the push rod 305 to the same axis as the magnets 309, the magnets 309 drive the iron rods 307 to move linearly through the attraction force, so that the iron rods 307 extending from the lifting plate 306 retract.

[0080] As an example, in this embodiment, magnets 310 are fixedly connected to both ends of the connecting plate 7. The two magnets 310 are respectively engaged with the two iron rods 307. The attraction force of magnets 310 on iron rods 307 is less than the attraction force of magnets 309 on iron rods 307.

[0081] In this embodiment, when the two folding blocks 315 move in opposite directions, they cause the push rod 313 to retract into the mounting cylinder 302. The sealing ring 314, in conjunction with the push rod 313, pushes the oil in the mounting cylinder 302 into the mounting cylinder 304 through the connecting pipe 303. The oil in the mounting cylinder 304 pushes the sealing ring 312, the push rod 305, the lifting plate 306, and the iron rod 307 to move linearly, causing the iron rod 307 to separate from the magnet 309.

[0082] Working principle: During use, the operator moves the two folding blocks 315 in opposite directions, causing the positioning block 317 and the push rod 313 to move, retracting the push rod 313 into the mounting cylinder 302. Simultaneously, the elastic element 316 contracts. The plate 311 is then placed between the two folding blocks 315. After releasing the two folding blocks 315, the elastic element 316 clamps and fixes the plate 311. The positioning block 317 then restricts the side plates of the plate 311, improving the stability of the plate 311 on the die 3 and enhancing the stability of subsequent stamping processes. Subsequently, the operator controls the hydraulic cylinder 4 via an external hydraulic system, causing the connecting plate 7 and the elastic element 8 to move linearly. When elastic element 7 moves, it drives connecting plate 9, punch 10, and die 3 to move linearly. After die 3 is restricted, connecting plate 7, connecting plate 9, and punch 10 can continue to move, but elastic element 8 will be compressed. After punch 10 contacts plate 311, it squeezes plate 311 to deform, causing plate 311 to enter the interior of die 3, thereby stamping plate 311 into a U-shape. By utilizing the segmented elastic buffer design of elastic element 8, elastic element 6, and elastic element 701, damage to the zinc layer on the surface of plate 311 is reduced, which is beneficial to improving the quality of the stamped product. When the two folding blocks 315 move in opposite directions, they drive push rod 313 to retract into mounting cylinder 302. Sealing ring 314 cooperates with push rod. The oil in the first mounting cylinder 302 is pushed into the second mounting cylinder 304 through the connecting pipe 303. The oil in the second mounting cylinder 304 pushes the sealing ring 312, the push rod 305, the lifting plate 306, and the iron rod 307 to move linearly, causing the iron rod 307 to separate from the magnet 309, making it easier for the iron rod 307 to reach the lowest point. When the connecting plate 7 moves, it drives the magnet 310 to move. When the magnet 310 is on the same axis as the iron rod 307 at the lowest point, the attraction force of the magnet 310 on the iron rod 307 pulls the iron rod 307 out of the lifting plate 306. At this time, the iron rod 307 comes into contact with the outer surface of the connecting plate 7. Then, the operator controls the output end of the hydraulic cylinder 4 to retract through the external hydraulic system, which drives the connecting plate 7 to move. 7. The iron rod 307, lifting plate 306, push rod 2 305, and sealing ring 2 312 move upward linearly, causing the oil inside the mounting cylinder 2 304 to enter the inner wall of the mounting cylinder 1 302 through the connecting pipe 303. This, in turn, pushes the sealing ring 1 314 and push rod 1 313 to move, facilitating relative movement between the two push rods 1 313. This, in turn, drives relative movement between the two folding blocks 315 and the positioning block 317, which is beneficial for the secondary stamping of the U-shaped plate 311, making the plate 311 into a rectangular shape. When the two positioning blocks 317 are in contact, they interact, compressing the elastic element 5 319, facilitating relative movement between the positioning block 317 and the folding block 315, and facilitating contact between the outer surfaces of the two folding blocks 315.This is beneficial for improving the product quality of 311 sheet metal stamped into a rectangular shape.

[0083] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
