Description

Technical Field

[0001] The invention belongs to the technical field of copper alloy processing equipment, in particular to an extrusion molding equipment for copper alloy. Background Art

[0002] There are many types of products corresponding to copper alloy materials. For example, a brass rod is a rod structure of a copper and zinc alloy, which is used in many fields. At present, the copper alloy rod is mainly extruded by a traditional horizontal extruder. Specifically, when making the current brass rod, the brass billet is heated and then put into the extruder cavity for extrusion. After forming, it is cooled and cut into sections. The inventor believes that the disadvantage of the current technology is that the process of making the brass billet is relatively simple in the early stage, and it is directly formed by cooling. Before casting, the molten metal generally contains a certain amount of air, so that after the brass billet is made, the metal density is easily uneven inside the material. In the process of extruding it into a rod body through an extruder, the equipment still cannot eliminate the gaps in the material, resulting in the phenomenon that the rod structure still has the phenomenon of uneven metal density. For example, in response to this problem, after searching, the Chinese utility model patent with publication number CN217858077U once disclosed a copper alloy bar extrusion forming die (the detailed structure can be read in the original document), in which the extrusion head is mainly driven to rotate by a rotating rod, thereby driving the molten metal poured into the die cavity to rotate, realizing centrifugal operation; When there is uneven or substandard metal density in the rod body, it will affect the structural strength of the product to a certain extent, causing the product quality to be substandard, so it becomes a problem that needs to be solved urgently; in the above-mentioned patents, the rotation of the molten metal is achieved through the action of the extrusion head, but due to the lack of components to eliminate bubbles, the separated bubbles cannot be removed well. At the same time, it only contacts the molten metal through the extrusion head. Due to the limited contact, the rotation of the extrusion head cannot ensure that the molten metal is driven to rotate synchronously to achieve the centrifugal effect. In summary, in the face of the problems existing in the prior art, the present invention will provide an extrusion molding equipment for copper alloys. Summary of the invention

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Reference Figure 10-12 In view of the fact that the blank contains foreign matter such as air components, thereby affecting the final forming quality of the alloy bar, an embodiment of the present invention provides an extrusion forming device for copper alloys, wherein the fixed point position on the device has an axial path, and the axial path is Fig.10 In the direction indicated by the middle arrow, the alloy billet moves along the axial path when being loaded on the equipment. In addition to this, the present invention also includes the following parts: The container 100 is rotatably arranged relative to the axial path, and its rotation axis is consistent with the axial path, and has a heating chamber 101 for accommodating the blank. The heating chamber 101 is cylindrical, consistent with the shape of the blank, slightly larger than the size of the blank, and coaxial with the axial path. At least one end of the heating chamber 101 has an extrusion port 102, which is used for extruding the copper alloy rod, and the extrusion port 102 has a cooling function; The extrusion part 200 and the collection part 300, the extrusion part 200 is used to apply force to the heating chamber 101 along the axial path direction, so as to squeeze the inner space thereof, the collection part 300 is linearly movable along the axial path direction, and has a through cavity 301 formed along the axial path direction, when the collection part 300 and the extrusion part 200 move into the heating chamber 101 during operation, the collection part 300 enters the heating chamber 101 before the extrusion part 200; The process of implementing billet extrusion in the present invention is as follows: The blank is placed on the axial path and is pushed into the heating chamber 101 by the force of the extrusion unit 200. After the blank enters the heating chamber 101, the extrusion port 102 remains blocked and the force of the extrusion unit 200 stops. The heating chamber 101 heats the blank until the blank is melted, and then stops heating. In the above process, the container 100 rotates, and the molten metal 1000 is driven to rotate, thereby achieving a centrifugal effect. Fig.11 As shown, during the centrifugation of the melt 1000, the air 1100 in the composition is separated and reaches the center of rotation, that is, the axial path. At the same time, some foreign matter 1200 in the melt 1000, such as oxide slag and impurities, is also centrifuged out and distributed at the center of the rotation axis. Continuing, the collecting part 300 and the extruding part 200 enter the heating chamber 101 in sequence. When the collecting part 300 enters the heating chamber 101, as shown in FIG. Fig.12 As shown, the foreign matter 1200 and the air body 1100 are separated from the melt 1000, so as to achieve separation. The foreign matter 1200 and the air body 1100 enter the cavity 301 until the collecting part 300 completely enters the heating chamber 101, so as to achieve separation. The foreign matter 1200 and the air body 1100 are separated in the cavity 301 until the collecting part 100 stops rotating; Next, the extrusion unit 200 enters the heating chamber 101 to extrude the melt 1000. When the blocking state of the extrusion port 102 is released, the melt 1000 is extruded from the extrusion port 102. When the melt 1000 reaches the extrusion port 102, due to the cooling effect of the extrusion port 102, the melt 1000 solidifies and is formed into a rod structure. Until the extrusion unit 200 extrude the heating chamber 101 into place along the axial path, a copper alloy rod is completely formed. Compared with the prior art, the present invention not only realizes the discharge of air 1100 in the metal material, but also realizes the discharge of some solid foreign matter 1200, such as waste slag and impurities, making the metal material purer. In addition, during the extrusion process, the metal material of the present invention is in a molten state. Compared with the semi-molten state in the prior art, the phenomenon of the internal structure of the material being pulled can be reduced, that is, the generation of internal stress of the material can be reduced, so that the internal material structure of the formed rod is more stable, thereby better ensuring the final product quality.

[0035] Based on the above description of the present solution, a preferred structural form of the device in the present invention will be described in detail below, specifically: Reference Figure 1-Figure 9 , one end of the heating chamber 101 is a closed structure, and the other end is an open structure, the extrusion port 102 is located at the closed end of the heating chamber 101, the extrusion part 200 includes an extrusion shaft 201 and a pressing block 202, the extrusion shaft 201 can be linearly movable along the axial path direction, the pressing block 202 is rotatably arranged at one end of the extrusion shaft 201, the pressing block 202 is used to contact the blank, and its size is adapted to the diameter of the heating chamber 101, through the movement of the extrusion shaft 201, the pressing block 202 is driven to push and extrude the blank into the heating chamber 101, through the rotation relationship between the pressing block 202 and the extrusion shaft 201, during the rotation of the heating chamber 101, the pressing block 202 can rotate synchronously with it, thereby reducing the rotation resistance caused to the container 100, and avoiding the structural wear caused by mutual friction; Regarding the power configuration of the extrusion shaft 201, the device also includes a base 400, which serves as the frame of the entire device. The axial path can be regarded as a fixed position on the base 400. The base 400 is provided with a cylinder 900, which is located on the axial path. The extrusion shaft 201 is connected to the movable end of the cylinder 900, and the cylinder 900 is used to drive the movement of the extrusion shaft 201. Regarding the configuration of the cooling function on the extrusion port 102, the extrusion port 102 can be a tube head-shaped structure, and a water-cooling nozzle acting on the tube head structure can be provided at a fixed position on the base 400 to achieve a cooling effect at the extrusion port 102; Reference Figure 8 and Fig. 9, one end of the extrusion shaft 201 is connected to a connection seat 204 through a spring mechanism 203, and the pressing block 202 forms a rotational fit with the connection seat 204, so as to achieve a rotation effect at one end of the extrusion. The spring mechanism can be formed by a plurality of spring plates. Through the connection of the spring mechanism, there is a certain movable effect between the connection seat 204 and the end of the extrusion shaft 201, so as to keep the pressing block 202 at the position where the end of the extrusion shaft 201 is located, so as to be able to move or move. When the heating chamber 101 rotates, even if the extrusion shaft 201 and the heating chamber 101 do not maintain an absolute coaxial relationship, the movement process can be avoided from being blocked by the offset of the pressing block 202 on the extrusion shaft 201; Reference Figure 8 , Fig. 9 , Fig.10 and Fig.12 The collecting part 300 is in the shape of a tube, so as to maintain a hollow structure inside itself to form the structure of the containing cavity 301. The collecting part 300 moves through the pressing block 202, so that the collecting part 300 can slide on the pressing block 202 in the direction of the axial path, and the collecting part 300 cooperates with the containing part 100. When the rotation speed of the containing part 100 reaches a certain level, the collecting part 300 can move on the pressing block 202 toward the heating chamber 101 through the linkage relationship. When the melt 1000 is centrifuged, the rotation speed of the containing part 100 can be increased in the form of a gradient. It is now assumed that the speed that can drive the collecting part 300 to move is the threshold speed. During centrifugation, the containing part 100 can work for a period of time at a rotation speed lower than the threshold speed, thereby completing the separation of the foreign matter 1200 in the melt 1000, and then work for a period of time at a state higher than the threshold speed, during which the melt 1000 and the foreign matter 1200 are kept at a relative position. Fig.11 The state shown, and at the same time the collecting part 300 moves into the heating chamber 101, thereby realizing the collection of foreign matter 1200 and air body 1100, the linkage effect ensures the coherent effect of each component participating in each stage in turn, compared with the manual control method, it has higher work efficiency, about the rotation process of the containing part 100, the containing part 100 can be directly rotatably set on the base 400, and the base 400 is provided with a driving motor 402, which can establish a transmission relationship with the containing part 100, such as the outer peripheral side of the containing part 100 can be provided with a driven gear, and the driving motor 402 can be configured to establish transmission between the driving gear and the driven gear, and the driving motor 402 preferably adopts a servo motor so that its rotation angle can be controlled to ensure that when the containing part 100 stops rotating, the extrusion port 102 is kept in a fixed position each time, so as to facilitate the delivery of the formed rod to the rear end process by setting up a receiving device.

[0036] For the linkage method described, refer to Figure 2 and Figure 4-Figure 7 The heating chamber 101 is closed at one end and is configured with a slag discharge port 103, which is located on the axial path. In terms of positional relationship, when the collecting portion 300 moves to the bottom inside the heating chamber 101, one end of the collecting portion 300 will eventually hit the edge of the slag discharge port 103, and the containing chamber 301 is just facing the slag discharge port 103. A movable pushing portion 301a is sealed in the containing chamber 301, and the pushing portion 301a is elastically connected to the collecting portion 300. When the rotation speed of the containing portion 100 reaches a threshold speed, the containing portion 100 will apply force to the pushing portion 301a, so that the pushing portion 301a drives the collecting portion 300 to move through the elastic connection. In this process, Fig.12 As shown, when one end of the collecting part 300 moves to the right position and contacts the slag discharge port 103, due to the elastic connection, the pushing part 301a can continue to move relative to the collecting part 300. The pushing part 301a pushes the waste stored in the cavity 301 during the movement in the cavity 301, and finally pushes the waste to the slag discharge port 103 for discharge, thereby automatically realizing the centralized collection of the waste. If the waste contains certain metal resources, it can be put into the furnace for refining. The slag discharge port 103 is connected with a cover plate 800 through an elastic metal sheet, which normally covers the slag discharge port 103. When the waste is squeezed out, the cover plate 800 is pushed away from the slag discharge port 103 to discharge the waste. Reference Figure 3-Figure 7 The container 100 includes a waiting section 100a and a heating section 100b along the axial path direction, and the complete part of the heating chamber 101 is located in the heating section 100b. The inner wall of the waiting section 100a is made of metal, so as to ensure that the wall surface has a certain strength and can cope with the hard collision of the blank when entering. The inner wall of the heating section 100b is made of non-metal, so as to reduce the phenomenon of high temperature in the melt 1000 being transferred to other places, play a role in protecting the equipment, and reduce heat loss. When the pressing block 202 is active, it passes through the waiting section 100a and the heating section 100b in sequence along the axial path direction, so as to realize the process of squeezing the blank into the heating chamber 101 and squeezing the melt 1000 in sequence. The closed structure on the heating chamber 101 is located at one end of the heating section 100b; Reference Figure 3-Figure 7The container 100 is structurally composed of at least an outer layer 104 and an inner layer 105. The outer layer 104 is sized to cover the material waiting section 100a and the heating section 100b. The inner layer 105 is completely distributed throughout the heating section 100b. The inner layer 105 is made of ceramic. The ceramic structure can reduce the temperature transfer while ensuring a certain structural strength. The outer layer 104 is sleeved on the inner layer 105, so that the wall surface of the heating section 100b is composed of ceramic. The inner wall surface of 00a is composed of an outer layer 104, and the outer layer 104 can be made of tungsten steel or high carbon steel, etc. A heating coil 105a is embedded in the wall thickness of the inner layer 105. The heating coil 105a is used to induction preheat the blank, thereby realizing the melting process of the blank. The ceramic material of the inner layer 105 can avoid the thermal effect of the heating coil 105a. The outer layer 104 maintains a rotational connection with the base 400, and the driven gear can be arranged on the outer layer 104.

[0037] Reference Figure 3-Figure 7 , an air guide area 600 is provided between the outer layer 104 and the base 400, and an air compression mechanism 500 is provided in the air guide area 600 for compressing and discharging air. The air compression mechanism 500 automatically enters a working state when the outer layer 104 is in a rotating state, and an air storage chamber 201a is provided on the extrusion shaft 201, which has a linear extension structure, and a piston 201b is arranged in the air storage chamber 201a, which is hard-connected with the pushing portion 301a, and one end of the air guide area 600 is connected with the air storage chamber 201a, and the extrusion shaft 201 is also provided with an air discharge channel 201c for keeping the air storage chamber 201a connected with the outside, so that when the container 100 rotates, the air compression mechanism 500 compresses the air into the air guide area 600 and discharges it into the air storage chamber 201a , and then discharged through the air leakage channel 201c. When the rotation speed of the container 100 does not reach the threshold speed, the working efficiency of the air compression mechanism 500 does not reach a certain level, the air entering the air storage chamber 201a is limited, the air pressure in the air storage chamber 201a is insufficient, and the air is normally discharged from the air leakage channel 201c. When the rotation speed of the container 100 reaches the threshold speed, the working efficiency of the air compression mechanism 500 increases accordingly, and the air leakage channel 201c is not exhausted in time, so that the air pressure in the air storage chamber 201a increases, and the piston 201b is pushed to move, so that the piston 201b completes the driving of the moving process of the pushing part 301a. In this process, the air compression mechanism 500 presses the external air into the air guide area 600 to achieve the heat dissipation effect on the base 400, thereby achieving the heat dissipation effect on the surface of the device; Reference Figure 6 and Figure 7The air guide area 600 includes an air inlet duct 601 and an air outlet duct 602 formed between the outer layer 104 and the base 400. Regarding the structure of the container 100, a plurality of air flow channels 106 are formed between the outer layer 104 and the inner layer 105. The plurality of air flow channels 106 are distributed in a ring array. The air flow channels 106 are connected between the air inlet duct 601 and the air outlet duct 602. The air compression mechanism 500 includes stator blades 501 and rotor blades 502 located in the air inlet duct 601. The number of the stator blades 501 and the rotor blades 502 can be multiple groups. The figure shows one group for reference. The stator blades 501 and the rotor blades 502 are fixedly connected to the base 400 and the outer layer 104 respectively. When the outer layer 104 rotates, the stator blades 501 and the rotor blades 502 cooperate to press the external air into the air inlet duct 601. , compressed air enters the air outlet duct 602 through the multiple air flow channels 106, and the air outlet duct 602 and the air storage chamber 201a can be connected through a soft tube body, and the display of the soft tube body is omitted in the figure. The compressed air in the outer duct enters the air storage chamber 201a through the soft tube body. In this process, the compressed air passes between the outer layer 104 and the inner layer 105, so as to have a heat dissipation effect on the overall structure of the container 100, especially on the ceramic material of the inner layer 105 to prevent its temperature from being too high. For the power supply of the heating coil 105a, a conductive slip ring mechanism can be arranged in the air outlet duct 602 or the air inlet duct 601, and the external power supply can be connected to the base 400. The conductive slip ring mechanism is used to realize the power supply process between the heating coil 105a that rotates synchronously with the container 100 and the power supply.

[0038] Reference Figure 3-Figure 7 The device also includes a bearing 700. A bearing seat 401 is constructed on the base 400, which is arranged between the intake duct 601 and the outlet duct 602. The bearing 700 is fixedly arranged on the bearing seat 401, and the outer layer 104 is assembled on the inner ring of the bearing 700. The bearing 700 here is a roller bearing 700. The bearing 700 ensures the stability of the entire container 100 when rotating on the base 400.

[0039] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
