Description

Technical Field

[0001] The invention relates to the technical field of die forging, and in particular to a die forging plate, a manufacturing method of a glove die and a die. Background Art

[0002] Die forging refers to a forging method that uses a die to shape a blank on a special die forging equipment to obtain a forging. The forgings produced by this method are accurate in size, have a small machining allowance, are relatively complex in structure, and have high productivity. Because the die cavity guides the flow of metal, the shape of the forging can be relatively complex. However, when die forging products with low thickness, some thinner positions are prone to tearing and breaking. This is because the product is too thin and there is no overall fluidity between the plates. In the weak part, the aluminum material will break when it exceeds its own limit elongation, forming a torn state. This is mainly caused by the thin material itself during the die forging process, which leads to insufficient local material at the die forging position. However, choosing a thicker material cannot achieve the wall thickness required by the product. Summary of the invention

[0003] Based on this, it is necessary to provide a forging plate, a method for making a glove mold and a mold.

[0004] A method for manufacturing a die forging plate comprises the following steps:

[0005] Providing a plate body;

[0006] A groove is formed in the plate body to obtain a preformed plate;

[0007] The preformed plate is placed in a mold for die forging to form model structures on both sides of the groove of the preformed plate to obtain a die forged plate; wherein the mold includes an upper mold and a lower mold, the upper mold is movably connected to the lower mold, the lower mold is provided with a protrusion, and the protrusion is used to penetrate into the groove of the preformed plate, the upper mold is provided with a first pressing structure, and the lower mold is provided with a second pressing structure, the second pressing structure is arranged on both sides of the protrusion, the first pressing structure is matched with the second pressing structure, and when the upper mold is connected to the lower mold, the first pressing structure and the second pressing structure are pressed on the preformed plate to form the model structure on the preformed plate.

[0008] In one of the embodiments, in the step of forming a groove in the plate body to obtain a preformed plate, the groove is formed in the plate body by a stamping process.

[0009] In one embodiment, the model structure includes a first extension portion and a second extension portion that are adjacent to each other, and the groove is disposed between the first extension portion and the second extension portion.

[0010] In one embodiment, the projection of the groove in the extension direction of the first extension part all falls on the first extension part, and the projection of the groove in the extension direction of the second extension part all falls on the second extension part.

[0011] In one embodiment, one end of the first extension portion is connected to one end of the second extension portion.

[0012] In one of the embodiments, the distance from the connection position between the first extension portion and the second extension portion to the groove is 3 mm to 5 mm.

[0013] In one embodiment, the model structure is configured as a palm-shaped structure, the palm-shaped structure has at least two finger-shaped structures, and the groove is configured between the two finger-shaped structures.

[0014] In one embodiment, the groove is a V-shaped groove.

[0015] A method for making a glove mold, comprising the method for making a die forging plate as described in any of the above embodiments, placing the preformed plate into a mold for die forging to form model structures on both sides of the groove of the preformed plate, and further comprising the following steps after the step of obtaining the die forging plate:

[0016] The flash at the edge of the model structure is cut off to obtain the glove mold.

[0017] A mold is used to perform die forging on a preformed plate, the mold comprising an upper mold and a lower mold, the upper mold is movably connected to the lower mold, the lower mold is provided with a protrusion, the protrusion is used to be inserted into a groove of the preformed plate, the upper mold is provided with a first pressing structure, the lower mold is provided with a second pressing structure, the second pressing structure is arranged on both sides of the protrusion, the first pressing structure is matched with the second pressing structure, when the upper mold is connected to the lower mold, the first pressing structure and the second pressing structure are pressed on the preformed plate to form a model structure on the preformed plate.

[0018] In the manufacturing method of the above-mentioned die forging plate, a groove is provided on the plate body, so that the bottom thickness of the groove of the preformed plate is thinner. During the die forging process, the bottom of the groove will be more easily torn than other positions of the preformed plate. When the bottom of the groove is torn, the edge of the groove can be deformed to both sides, sharing the force on the preformed plate and avoiding the preformed plate from being torn near the model structure. And because the edge of the groove can be pulled toward the position of the preformed plate near the model structure during the die forging process, these materials can be supplemented to the position of the preformed plate near the model structure to avoid the model structure from being torn due to insufficient materials. Therefore, after the groove is pre-formed on the plate body, it is helpful to better shape the model structure in the subsequent die forging steps and avoid the tearing of the model structure. It is particularly suitable for making thinner model structures and overcomes the problem that thinner die forging materials are easy to tear the model structure during the die forging process.

[0033] In one embodiment, a method for making a die forging plate comprises the following steps:

[0034] Provide a plate body.

[0035] A groove is formed in the plate body to obtain a preformed plate;

[0036] The preformed plate is placed in a die forging process to form model structures on both sides of the groove of the preformed plate to obtain a die forging plate; wherein the die includes an upper die and a lower die, the upper die is movably connected to the lower die, the lower die is provided with a protrusion, the protrusion is used to penetrate the groove of the preformed plate, the upper die is provided with a first pressing structure, the lower die is provided with a second pressing structure, the second pressing structure is provided on both sides of the protrusion, the first pressing structure is matched with the second pressing structure, when the upper die is connected to the lower die, the first pressing structure and the second pressing structure are pressed on the preformed plate to form the model structure on the preformed plate. The groove also cooperates with the protrusion of the die to play a positioning role, which can prevent the preformed plate from being offset during the die forging process.

[0037] like Figure 1 As shown, in one embodiment, a method for making a die forging plate is provided, comprising the following steps:

[0038] Step 11, providing a plate body. In this embodiment, the plate body is an aluminum alloy plate, and the material technical conditions of the aluminum alloy plate adopt the standard material recorded in the national standard GB / T3191. The specification technical conditions of the aluminum alloy plate are 205 mm in length, 135 mm in width, and 2 mm in thickness. The above materials and specifications are helpful to make a die-forged plate with a palm-shaped structure. In other embodiments, the plate body can also be other types of alloy plates, or a pure metal plate that is solid at room temperature. The material technical conditions and specification technical conditions of the plate body can be adjusted according to actual conditions.

[0039] Step 12, a groove is formed on the plate body to obtain a preformed plate. In this embodiment, a groove is formed on the plate body by a stamping process. Specifically, a first convex rib is provided on the punch, the plate body is provided on the working surface of the punch press, the punch moves toward the working surface, and the first convex rib impacts the plate body to form a groove. In this way, the thickness from the bottom of the groove to the other side of the plate body will be lower than the thickness of other positions of the plate body. In other embodiments, a pre-punching die is provided on the working surface, a second convex rib is provided on the die, the plate body is provided on the pre-punching die, and at least partially corresponds to the second convex rib, the punch moves toward the working surface, and pushes the plate body to move toward the pre-punching die, the second convex rib protrudes from the pre-punching die, and the reaction force provided to the plate body forms the groove on the plate body. The groove is provided on the plate body by stamping, which will not reduce the mass of the plate body itself, so that the groove still has a certain reliability, and avoids premature breakage during subsequent die forging. In other embodiments, a groove is formed on the plate body by a cutting machine. In other embodiments, the plate body is provided with the groove when it is integrally formed. It is understood that other existing technologies can also be used to open the groove on the plate. In this embodiment, the groove has a slender structure, that is, the length of the groove is much greater than the width, so that it is helpful for the groove to tear along the length direction. It is understood that the length direction can also be the extension direction of the groove on the surface of the plate. In this embodiment, the model structure is located on both sides of the extension direction of the groove, so that the bottom of the groove is teared directionally along the extension direction, and the tearing direction is avoided as much as possible toward the model structure, so as to avoid the crack after the groove is torn extending to the model structure.

[0040] Step 13, placing the preformed plate into a die forging process, so as to form model structures on both sides of the groove of the preformed plate, and obtain a die forging plate; wherein, the die includes an upper die and a lower die, the upper die is movably connected to the lower die, the lower die is provided with a protrusion, the protrusion is used to penetrate into the groove of the preformed plate, the upper die is provided with a first pressing structure, the lower die is provided with a second pressing structure, the second pressing structure is provided on both sides of the protrusion, the first pressing structure is matched with the second pressing structure, when the upper die is connected to the lower die, the first pressing structure and the second pressing structure are respectively pressed on the two opposite sides of the preformed plate to form the model structure on the preformed plate. It can be understood that the die forging plate mentioned above is a structure having a shape after the plate body is pressed. The model structure is distributed on both sides of the groove of the die forging plate, the model structure can be a whole, or it can be more than two, and the model structure can also be arranged around the groove. In other embodiments, a protrusion may be provided on the upper mold. In this case, the preformed plate needs to be fixed to the upper mold by using existing technologies such as bonding or magnetic connection so that the protrusion has a limiting effect.

[0041] In one embodiment, the following step is also included between step 12 and step 13: heating the preformed plate to the die forging temperature. Specifically, the preformed plate is heated to 520°C~550°C. In this embodiment, an electric heating furnace is used to heat the preformed plate to 520°C~550°C. After the preformed plate is heated to the die forging temperature, it is cooled to a preset temperature, and then the preformed plate is die forged. This helps the preformed plate to be more easily deformed and helps the die forging process. In one embodiment, the upper die and the lower die are heated to 520°C~550°C respectively, and then the preformed plate is die forged in the die. This helps to avoid a large temperature difference between the die and the preformed plate, thereby avoiding cooling of the preformed plate, which helps to die forge the preformed plate. In other embodiments, the upper die and the lower die are provided with a heating assembly, and the preformed plate at room temperature is arranged between the upper die and the lower die and heated, which helps to die forge the preformed plate. It is understood that the heating treatment of the upper die and the lower die during the die forging process can also be achieved by using the prior art not mentioned above, and this embodiment will not be described in detail. In one embodiment, during the die forging process, the initial forging temperature of the preformed plate is maintained at 470°C to 490°C, and the final forging temperature is maintained at 340°C to 360°C, so that the glove mold has a better structural strength and better avoids the occurrence of tearing defects.

[0042] In the manufacturing method of the above-mentioned die forging plate, the plate body is processed before die forging, that is, a groove is opened on the plate body. In this way, the bottom thickness of the groove of the preformed plate is thinner. During the die forging process, the bottom of the groove will be more easily torn than other positions of the preformed plate. When the bottom of the groove is torn, the edge of the groove can deform to both sides, sharing the force on the preformed plate, which is equivalent to buffering the position of the preformed plate close to the model structure, avoiding the tearing of the position of the preformed plate close to the model structure. And because the edge of the groove can be pulled toward the position of the preformed plate close to the model structure during the die forging process, these materials can be supplemented to the position of the preformed plate close to the model structure, avoiding the tearing of the model structure due to insufficient materials. It is particularly suitable for making thinner model structures, overcoming the problem that thinner die forging materials are easy to tear the model structure during the die forging process.

[0043] like Figures 2 to 5As shown, in one embodiment, a mold 10 is provided, which can also be called a mold for making a glove mold, or simply a glove making mold. The mold 10 is used to perform die forging on a preformed plate 300, and the mold 10 includes an upper mold 100 and a lower mold 200, the upper mold 100 is movably connected to the lower mold 200, the lower mold 200 is provided with a protrusion 210, and the protrusion 210 is used to penetrate into the groove 301 of the preformed plate 300, the upper mold 100 is provided with a first pressing structure 110, and the lower mold 200 is provided with a second pressing structure 220, the second pressing structure 220 is arranged on both sides of the protrusion 210, and the first pressing structure 110 is matched with the second pressing structure 220. When the upper mold 100 is connected to the lower mold 200, the first pressing structure 110 and the second pressing structure 220 are pressed on the preformed plate 300 to form a model structure 410 on the preformed plate 300.

[0044] The above-mentioned die 10 is used to make the die forging plate 400. The protrusion 210 of the die 10 is used to penetrate the groove 301 of the preformed plate 300, which helps to position the preformed plate 300. In the die forging process, the protrusion 210 can apply pressure to the bottom of the groove 301, which helps to tear the bottom of the groove 301. After the bottom of the groove 301 is torn, the tearing of the model structure (not shown) can be avoided because the force is shared. At the same time, the edge of the groove 301 can replenish the material of the model structure to avoid tearing due to insufficient molding material of the model structure. It is worth mentioning that Figure 3 In the preformed plate 300, the groove 301 is actually provided on a side of the preformed plate 300 that is not shown. In order to more conveniently check the relative positions of the groove 301 and the protrusion 210, Figure 3 The groove 301 on the other side of the preformed plate 300 is shown by a dotted line.

[0045] In one embodiment, the first pressing structure 110 is a palm-shaped protrusion, and the second pressing structure 220 is a palm-shaped depression. The palm-shaped protrusion is used to penetrate into the palm-shaped depression. The parts of the preformed plate 300 located on both sides of the groove 301 are clamped and pressed by the wall of the palm-shaped protrusion and the wall of the palm-shaped depression, and are forged into a palm-shaped structure. In this embodiment, the palm-shaped protrusion and the palm-shaped depression are used to form a palm-shaped structure on the preformed plate 300. According to actual needs, in other embodiments, the first pressing structure 110 and the second pressing structure 220 can also be other mutually matching shapes, which are used to forge the preformed plate 300 into a model structure 410.

[0046] In order to make the bottom of the groove easier to tear, in one embodiment, the groove is a V-shaped groove. In this embodiment, the protrusion is set to a triangular prism shape, so that it can match the V-shaped groove, the ridge direction of the triangular prism is parallel to the plane where the lower die is located, and one of the side surfaces of the triangular prism is connected to the lower die. In this embodiment, the plate body is thinnest near the bottom of the V-shaped groove, and it is easiest to tear here, so that the bottom of the groove is easier to tear in a direction. At the same time, the V-shaped groove has a change in slope and can be easily punched out by a punch press. At the same time, the stamping process can avoid consuming the mass of the plate body and help maintain the original material strength of the plate body. At the same time, the bottom of the V-shaped groove is the thinnest position of the preformed plate, and it can be easily torn in a direction according to the position of the bottom of the V-shaped groove during the die forging process.

[0047] like Figure 6 As shown, in one embodiment, the model structure 410 includes a first extension portion 420 and a second extension portion 430 that are adjacent to each other, and the groove 301 is disposed between the first extension portion 420 and the second extension portion 430. In this embodiment, the extension direction of the first extension portion 420 and the extension direction of the second extension portion 430 are not colinear, the first extension portion 420 is located on one side of the groove 301, and the second extension portion 430 is located on the other side of the groove 301. The first extension portion 420 and the second extension portion 430 are the model structure 410 after die forging, which are used after being cut from the die forging plate 400. In this embodiment, the groove 301 is provided to help prevent the first extension portion 420 and the second extension portion 430 from tearing. It is worth mentioning that, Figure 5 The bottom of the middle groove 301 has been torn apart after the die forging process, so the groove 301 can be seen at the side of the preformed plate 300 where the groove 301 was not visible originally.

[0048] In order to prevent the die forging plate 400 from breaking, in one embodiment, the projection of the groove 301 in the extension direction of the first extension part 420 all falls on the first extension part 420, and the projection of the groove 301 in the extension direction of the second extension part 430 all falls on the second extension part 430. That is, in this embodiment, the two ends of the groove 301 are closer to the inside relative to the end of the first extension part 420 or the end of the second extension part 430, or the two ends of the groove 301 are flush with the end of the first extension part 420 or the end of the second extension part 430. In this way, when the bottom of the groove 301 is torn, the bottom of the groove 301 is prevented from being excessively torn in the extension direction of the two ends of the groove 301, thereby preventing the die forging plate 400 from breaking.

[0049] In one embodiment, one end of the first extension portion 420 is connected to one end of the second extension portion 430. In this embodiment, the first extension portion 420 and the second extension portion 430 are arranged in a V shape, and the model structure 410 with a V-shaped structure can be well prepared by providing the groove 301.

[0050] To prevent the bottom of the groove 301 from tearing and affecting the model structure 410, in one embodiment, the distance between the connection position of the first extension part 420 and the second extension part 430 and the groove 301 is 3mm~5mm. After the bottom of the groove 301 is torn, the distance from the connection position is 3mm~5mm, which can effectively prevent the bottom of the groove 301 from continuing to tear in the direction of the connection position, thereby preventing the connection position of the first extension part 420 and the second extension part 430 from being torn.

[0051] Since the palm-shaped structure has a finger-shaped structure, and in the field of die forging, the finger-shaped structures are closely spaced and easily torn, in one embodiment, the model structure is set as a palm-shaped structure, the palm-shaped structure has at least two finger-shaped structures, and the groove is set between the two finger-shaped structures. In one embodiment, the model structure 410 is set as a palm-shaped structure, the palm-shaped structure has five finger-shaped structures, the number of the grooves 301 is four, and a groove 301 is set between two adjacent finger-shaped structures. In this embodiment, any two adjacent finger-shaped structures are equivalent to the first extension 420 and the second extension 430, respectively, and there is a finger web structure between the two finger-shaped structures, that is, the connection position of the first extension 420 and the second extension 430. In this embodiment, the distance from the finger web structure to the groove 301 is 3mm~5mm, so as to avoid the tearing of the finger web structure. During the die forging process, the groove 301 will be more easily torn than other positions of the preformed plate 300, so as to avoid the tearing of the palm-shaped structure, so that the palm-shaped structure can be prepared completely. In this embodiment, the groove is not protruding from the end of the finger-shaped structure, that is, the projection of the groove 301 in the extension direction of the first extension part 420 all falls on the first extension part 420, and the projection of the groove 301 in the extension direction of the second extension part 430 all falls on the second extension part 430.

[0052] In one embodiment, a method for making a glove mold is provided, comprising the method for making a die forging plate as described in any of the above embodiments, placing the preformed plate into a mold for die forging to form a model structure on both sides of the groove of the preformed plate, and after the step of obtaining the die forging plate, the following step is also included: cutting off the flash at the edge of the model structure to obtain the glove mold. In this embodiment, since the model structure is not torn during the die forging process, a complete glove mold can be obtained. Figure 7As shown, the glove mold 500 after the flash is removed, wherein Figure 7 The glove mold in the embodiment is a palm-shaped glove mold. In one of the embodiments, a cutting device is used to cut off the flash on the edge of the model structure. In one of the embodiments, the cutting device is a punching machine, and a cutter head is provided on the punch of the punching machine. The shape of the cutter head matches the outer contour of the model structure. When the punch hits the die forging plate once, the edge of the model structure can be completely removed, thereby improving the cutting efficiency. In one of the embodiments, the punching machine is provided with a bearing surface facing the cutter head, and a positioning mark portion is provided on the bearing surface. The shape of the positioning mark portion matches the outer contour shape of the glove mold. In this way, the model structure can be placed at a position close to the positioning mark portion on the bearing surface, and the glove mold is aligned with the positioning mark portion, so that the subsequent glove mold can be accurately cut out. In one of the embodiments, a 160T punching machine is used to cut off the flash on the edge of the model structure.

[0053] In one embodiment, the flash of the edge of the model structure is cut off when the die forging plate is in a cold state, so that the size change caused by the heat expansion of the die forging plate can be avoided, which helps to unify the size of the die forging plate during cutting, avoids misalignment during cutting, and helps to improve cutting accuracy. In one embodiment, the cold state is room temperature.

[0054] In one embodiment, a glove mold is provided, which is obtained by the manufacturing method of the glove mold in the above embodiment. In one embodiment, the thickness of the glove mold is 1 mm to 3 mm. In one embodiment, the thickness of the glove mold is one of 1 mm, 2 mm and 3 mm. The above manufacturing method can be used to better manufacture a glove mold with a thickness of 1 mm to 3 mm, and avoid tearing of the glove mold.

[0055] In one embodiment, after cutting off the flash on the edge of the model structure to obtain the glove mold, the following steps are also included: grinding the glove mold; acid-washing the polished glove mold; and visually inspecting the surface of the glove mold. Grinding the glove mold helps to remove burrs on the surface of the glove mold, making the glove mold smoother. Acid-washing the polished glove mold helps to remove oil stains on the surface of the glove mold. Visually inspecting the surface of the glove mold helps to identify defective glove molds. In one embodiment, after the step of visually inspecting the surface of the glove mold, the step of packaging the mold is also included to prevent external objects from damaging the mold.

[0056] Grinding the glove mold helps to make the surface of the glove mold smoother. However, some products have thin walls and are easily deformed during the grinding process. In one embodiment, the step of grinding the glove mold specifically includes: providing a bearing platform with a grinding shape, the grinding shape matches the model structure, and it can also be understood that the structure of the grinding shape is the same as the first pressing structure; putting the concave surface of the glove mold on the grinding shape so that the glove mold obtains support from the grinding shape; using corundum micropowder with a particle size of 280 mesh to 300 mesh to wash the surface of the glove mold to remove burrs on the surface of the glove mold. In this embodiment, since the glove mold obtains support from the grinding shape, the glove mold is prevented from being deformed by impact during the sanding process. That is, in this embodiment, the grinding shape of the bearing platform can cooperate well with the sanding process, and is particularly suitable for processing products with thin walls of the glove mold, which helps to make the surface of the processed glove mold smoother and smoother. After testing, it was found that the burrs on the surface of the glove mold can be removed well by using corundum micropowder with a particle size of 280-300 meshes, which is particularly suitable for standard materials recorded in the national standard GB / T3191. The surface of the product after grinding is smooth, and the surface roughness reaches the standard of Ra1.6 after grinding. Moreover, it only needs to be polished once, and there is no need to frequently change the grinding conditions, which improves the grinding efficiency and saves the grinding time. In other embodiments, a grinder is used to grind the glove mold to remove the burrs on the glove mold and eliminate the burr defects on the surface of the glove mold.

[0057] In one embodiment, the polished glove mold is pickled by a pickling device. The pickling device includes a pickling tank, in which a bracket for carrying the glove mold is provided, and a through groove is provided near the opening of the pickling tank, and the through groove is closed by a plug. Since oil stains will float out of the glove mold after pickling, after the pickling is completed, the plug can be opened so that the pickling liquid on the upper layer can be discharged together with the oil stains through the through groove, which can avoid the accumulation of oil stains and help prevent the glove mold from being contaminated by oil stains again when the glove mold is taken out, thereby improving the cleanliness of the glove mold. After the oil stains and part of the pickling liquid are discharged, the pickling liquid is continued to be added to the pickling tank so that the pickling tank has enough pickling liquid.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
