All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0047] In the description of the utility model, it needs to be explained that if the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the utility model product is used, it is only for the convenience of describing the utility model and simplifying the description, and it is not intended to indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0048] In addition, if the terms "first", "second" and the like are used only to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0049] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0050] Please refer to Figures 1-3 , Figure 1 The structure schematic view of the continuous extrusion forming device 100 provided in the embodiment; Figure 2 The cross-sectional view of the continuous extrusion forming device 100 provided in the embodiment; Figure 3 The structure schematic view of the continuous extrusion forming device 100 provided in the embodiment; Figure 2 The local enlarged view of A in the embodiment.

[0051] The utility model provides a kind of continuous extrusion forming device 100, the continuous extrusion forming device 100 includes extrusion wheel 110 and forming die 120, forming die 120 cooperates with extrusion wheel 110;Extrusion wheel 110 outer wall is provided with annular groove 111 and at least one annular protrusion 112 around the axis of annular groove 111, annular protrusion 112 is arranged at the notch of annular groove 111, and protrude along the mirror direction of annular groove 111;Wherein, when extrusion wheel 110 and forming die 120 cooperate with each other, extrusion wheel 110 is used to extrude material into forming die 120.

[0052] It can be understood that annular groove 111 and annular protrusion 112 in the embodiment are arranged around the same axis, and the recess direction of annular groove 111 and the protruding direction of annular protrusion 112 are opposite, so that the outer wall of extrusion wheel 110 is uneven.The axis of annular groove 111, the axis of annular protrusion 112 and the axis of extrusion wheel 110 in the embodiment are the same axis.

[0053] Since the material in the embodiment is heated metal, at this time, the heated metal has thermoplasticity, so its shape will change under the action of extrusion force.

[0054] When the extruding wheel 110 and the forming die 120 cooperate to extrude the material, the material will enter the forming die 120 under the extruding action of the extruding wheel 110, thereby forming the required product. However, since there is a gap between the extruding wheel 110 and the forming die 120, the material will overflow along the axial direction of the extruding wheel 110.

[0055] However, because the outer wall of the extruding wheel 110 is uneven, the overflow path of the overflowed material has multiple corners, thereby causing the overflow path to be relatively complex, making it difficult for the material to overflow, thereby reducing the overflow rate of the material, improving the utilization rate of the material, and reducing the cost.

[0056] According to the above, in the present embodiment, the groove width of the annular groove 111 gradually increases from the groove bottom to the groove opening, and the cross section of the groove bottom of the annular groove 111 in the direction perpendicular to the axis of the annular groove 111 is arc-shaped.

[0057] Specifically, the present embodiment further increases the unevenness of the extruding wheel 110 and the roughness of the outer wall of the extruding wheel 110 by gradually increasing the groove width from the groove bottom of the annular groove 111 to the groove opening of the annular groove 111, thereby forming multiple corners, thereby avoiding material overflow, reducing the overflow rate of the material, reducing the cost, and improving the production efficiency.

[0058] It can be understood that if the annular groove 111 has a structure with a right angle, etc., the material is easy to remain, thereby causing the material to be not fully utilized, so the groove bottom of the annular groove 111 is set to be arc-shaped in the present embodiment.

[0059] Further, please refer to Figures 1-7 , Figure 4 the explosion schematic view of the forming die 120 provided for the present embodiment; Figure 5 the cross-sectional view of the forming die 120 provided for the present embodiment; Figure 6 the structural schematic view of the first die body 121 provided for the present embodiment; Figure 7 the structural schematic view of the material guide 122 provided for the present embodiment.

[0060] The forming die 120 in the present embodiment includes a first die body 121 and a material guide 122; the first die body 121 is provided with a material inlet channel 1211 and an extruding surface 1212, the extruding surface 1212 is used for cooperating with the extruding wheel 110; the extruding surface 1212 is provided with at least one sliding groove 1213; the material guide 122 is connected to the extruding surface 1212 and is used for guiding the material into the material inlet channel 1211; the material guide 122 is provided with at least one material guide groove 1221, each sliding groove 1213 is continuous with one material guide groove 1221; wherein the sliding groove 1213 and the material guide groove 1221 are both used for cooperating with the annular protrusion 112.

[0061] Specifically, the first die body 121 has a pressing surface 1212 configured to cooperate with the outer wall of the pressing wheel 110 to press the material to the feeding port of the feeding channel 1211; wherein the pressing surface 1212 is an arc surface.

[0062] In addition, the pressing surface 1212 is connected with a material guide 122, when the material moves to the feeding port of the feeding channel 1211 under the action of the pressing wheel 110, the material changes the direction of movement due to the blockage of the material guide 122, so as to enter the feeding channel 1211 and move along the axis direction of the feeding channel 1211.

[0063] In the embodiment, a chute 1213 is arranged on the pressing surface 1212, and a material guide groove 1221 is arranged on the material guide 122, the material guide groove 1221 and the chute 1213 are continuous, and it can be understood that the material guide groove 1221 and the chute 1213 can be regarded as one structure, and are both configured to cooperate with the pressing wheel 110, so as to not hinder the movement of the pressing wheel 110.

[0064] The chute 1213 and the material guide groove 1221 both cooperate with the annular protrusion 112, so that the overflow path of the material has multiple corners, that is, a non-linear path, thereby reducing the overflow rate of the material, improving the utilization rate of the material, reducing the cost and improving the production efficiency.

[0065] According to the above content, please refer to Figures 1-7 In the embodiment, the material guide 122 is located below the feeding port. It can be understood that the material moves from top to bottom, and after being blocked by the material guide 122 below the feeding port, the material moves into the feeding channel 1211, and part of the material will overflow to both sides of the feeding port.

[0066] Therefore, in the embodiment, the number of the annular protrusions 112, the chute 1213 and the material guide groove 1221 is two; the annular groove 111 is located between the two annular protrusions 112; and the feeding port of the feeding channel 1211 is located between the two chutes 1213.

[0067] It should be noted that in the embodiment, the material guide 122 is provided with a material guide protrusion 1222, and the material guide protrusion 1222 is located between the two material guide grooves 1221; the material guide protrusion 1222 is configured to guide the material into the feeding channel 1211.

[0068] Specifically, when the extrusion wheel 110 and the first mold body 121 cooperate to extrude the material, the material moves downward from the top. When the material moves to the material guide protrusion 1222, the material guide protrusion 1222 hinders the movement of the material, thereby causing the material to change its direction of movement and enter the feed channel 1211; and, part of the material will overflow to both sides of the protrusion, thereby preventing the overflow of the material through the annular protrusion 112, the slide groove 1213 and the material guide groove 1221, thereby reducing the overflow rate of the material and improving the utilization rate of the material, thereby reducing costs and improving production efficiency.

[0069] For further information, please refer to Figures 1-7 In this embodiment, the first mold body 121 is provided with a receiving groove 1214, the receiving groove 1214 is located at the feed port of the feed channel 1211, and the receiving groove 1214 is connected to the feed channel 1211; the slide groove 1213 is connected to the receiving groove 1214; wherein, the material guide member 122 is detachably arranged in the receiving groove 1214.

[0070] It is understandable that when the material guide 122 is worn, repair can be completed by directly replacing the material guide 122 without replacing the entire forming mold 120, thereby reducing costs and improving production efficiency.

[0071] Based on the above settings, please refer to Figures 1-7 The slide groove 1213 is disconnected by the receiving groove 1214, thereby being divided into a first part and a second part. When the guide member 122 is placed in the receiving groove 1214, the guide groove 1221 is continuous with the first part and the second part, that is, the first part, the guide groove 1221 and the second part are connected in sequence; thereby enabling the extrusion wheel 110 to cooperate with the forming mold 120.

[0072] For further information, please refer to Figures 1-10 , Figure 8 A schematic structural diagram of the formed part 1242 provided in this embodiment; Figure 9 A schematic structural diagram of the gasket 1243 and the elastic member 125 provided in this embodiment from a first perspective; Figure 10 This is a schematic structural diagram of the gasket 1243 provided in this embodiment from a second perspective.

[0073] In this embodiment, the forming mold 120 also includes a second mold body 123 and a forming unit 124; the second mold body 123 is detachably connected to the first mold body 121; one or both of the first mold body 121 and the second mold body 123 are provided with a accommodating cavity 101, and the forming unit 124 is detachably arranged in the accommodating cavity 101; the second mold body 123 is provided with a discharge channel 1231, and the forming unit 124 is provided with a forming channel 1241; wherein, when the first mold body 121, the second mold body 123 and the forming unit 124 are in a mold closing state, the feed channel 1211, the forming channel 1241 and the discharge channel 1231 are connected to each other.

[0074] Specifically, after the material enters the feed channel 1211, the material passes through the feed channel 1211, the forming channel 1241 and the discharge channel 1231 in sequence, wherein the material will form the shape of the desired product in the forming channel 1241, and finally leave the forming mold 120 through the discharge channel 1231 to obtain the desired product.

[0075] In this embodiment, the first mold body 121 and the second mold body 123 are detachably connected, and the forming unit 124 is detachably arranged in the accommodating cavity 101, so that when the first mold body 121, the first mold body 121 or the forming unit 124 is worn, the repair can be completed by replacing the worn structure without replacing the entire forming mold 120, thereby reducing the subsequent maintenance cost and improving the subsequent maintenance efficiency.

[0076] Based on the above settings, please refer to Figures 1-10 In this embodiment, the forming mold 120 also includes a plurality of elastic members 125 arranged in a circular array around the axis of the accommodating cavity 101. The elastic members 125 are located in the accommodating cavity 101, and the two ends of the elastic members 125 are respectively connected to the inner wall of the accommodating cavity 101 and the forming unit 124; wherein, the expansion and contraction direction of the elastic members 125 is parallel to the movement direction of the material.

[0077] It should be noted that when the first mold body 121 , the second mold body 123 and the forming unit 124 are in the mold clamping state, the axis of the forming channel 1241 , the axis of the accommodating cavity 101 and the axis of the discharge channel 1231 coincide with each other.

[0078] Understandably, please refer to Figures 1-10 As the material moves from the feed channel 1211 to the forming channel 1241, it exerts pressure on the forming unit 124. The forming unit 124, in turn, exerts a reaction force on the material. This reaction force from the forming unit 124 causes the material to move in the opposite direction, toward the feed port of the feed channel 1211, causing the material at the feed port to overflow to both sides.

[0079] Therefore, in this embodiment, an elastic member 125 is provided to be connected to the forming unit 124 and the first mold body 121. The elastic force of the elastic member 125 is used to balance the reaction force of the forming unit 124, thereby preventing the material from moving in the opposite direction, and further preventing the material from overflowing to both sides of the feed port, thereby reducing the overflow rate of the material, improving material utilization, and reducing costs.

[0080] For further information, please refer to Figures 1-10 The forming unit 124 includes a forming member 1242 and a gasket 1243. The forming member 1242 has a guide protrusion 1242a and a plurality of forming holes 1242b, which are arranged in a circular array around the guide protrusion 1242a. The gasket 1243 has a through hole 1244, into which the forming member 1242 is detachably mounted. Specifically, in this embodiment, the gasket 1243 is provided to protect the forming member 1242, thereby extending the service life of the forming member 1242.

[0081] The guide protrusions 1242a divide the material and guide it toward the forming holes 1242b located around them, so that the material can move smoothly to the forming holes 1242b and then be formed into the shape of the desired product. Multiple forming holes 1242b are provided to form multiple desired products, thereby improving production efficiency.

[0082] Moreover, in this embodiment, the inner wall of the gasket 1243 is stepped along the axial direction of the through hole 1244; the side of the gasket 1243 close to the feed channel 1211 is the first side; the side of the gasket 1243 away from the feed channel 1211 is the second side; the cross-sectional area of ​​the through hole 1244 on the first side is smaller than the cross-sectional area of ​​the through hole 1244 on the second side.

[0083] It should be noted that, since the volume of the gasket 1243 is smaller than the volume of the accommodating chamber 101 , this embodiment is provided with a filling piece 126 for filling the accommodating chamber 101 so that the material can smoothly enter the discharge channel 1231 and avoid the material from being retained in the accommodating chamber 101 .

[0084] Understandably, please refer to Figures 1-10In this embodiment, because the through hole 1244 of the gasket 1243 is stepped and the diameter of the formed part 1242 is constant, the formed part 1242 does not completely fill the through hole 1244. A certain gap exists between the inner wall of the formed part 1242 and the gasket 1243. Therefore, when the material is subjected to the reaction force from the formed part 1242, the material in the gap moves in the opposite direction, thereby applying force to the inner wall of the gasket 1243. The spring connected to the gasket 1243 balances this reaction force through elastic force, thereby preventing the material in the feed channel 1211 from moving in the opposite direction and thus preventing the material from overflowing from the feed port. This reduces the material overflow rate, improves material utilization, and reduces costs.

[0085] In other embodiments, the cross-sectional area of ​​the through hole 1244 may gradually increase along the moving direction of the material, that is, the through hole 1244 may be trumpet-shaped.

[0086] In summary, the continuous extrusion forming device 100 includes an extrusion wheel 110 and a forming die 120, and the forming die 120 cooperates with the extrusion wheel 110; the outer wall of the extrusion wheel 110 is provided with an annular groove 111 and at least one annular protrusion 112 arranged around the axis of the annular groove 111, and the annular protrusion 112 is arranged at the notch of the annular groove 111 and protrudes along the mirror direction of the annular groove 111; wherein, when the extrusion wheel 110 and the forming die 120 cooperate with each other, the extrusion wheel 110 is used to extrude the material into the forming die 120.

[0087] It is understood that when the extrusion wheel 110 and the extrusion forming die 120 cooperate with each other, the annular protrusion 112 is located within the chute 1213 and the material guide trough 1221 and cooperates with the chute 1213 and the material guide trough 1221; thereby, the space within the chute 1213 and the material guide trough 1221 is reduced, and the amount of overflowing material that can be accommodated in the chute 1213 and the material guide trough 1221 is reduced. In addition, after the chute 1213 and the material guide trough 1221 cooperate with the annular protrusion 112, the accommodating space in the chute 1213 and the material guide trough 1221 in the direction of movement of the overflowing material is U-shaped, that is, the overflow path of the material has a corner, the overflow path structure is complex, and thus makes the material movement difficult, thereby reducing the material overflow rate, improving material utilization, and reducing costs.

[0088] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
