DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1 to Figure 5As shown, the present invention discloses a bimetallic composite material production device and method.

[0027] The bimetallic composite material production equipment comprises a cladding blank making device 10, a substrate blank making device 20, a bimetallic blank assembling device 30, a shaping and welding assembly 40 and a heating and forming assembly 60 which are arranged in sequence.

[0028] The cladding material blanking device 10 comprises a rolling cutting assembly and a groove forming assembly which are arranged in sequence. The cladding material passes through the rolling cutting assembly and the groove forming assembly in sequence, and the rolling cutting assembly and the groove forming assembly are used to cut and press the cladding material.

[0029] The above-mentioned rolling cutting assembly and the groove forming assembly are located on the same plane. The above-mentioned rolling cutting assembly includes an upper roller 101 and a lower roller 102 correspondingly arranged up and down, and the upper roller 101 and the lower roller 102 are staggered to achieve cutting of the covering material, so that the wide covering material is cut into a narrow covering material. The above-mentioned groove forming assembly includes an upper forming knife 103 and a lower forming knife 104 correspondingly arranged, and the upper forming knife 103 and the lower forming knife 104 are staggered to achieve pressing of the narrow covering material.

[0030] When the cladding blank making device 10 is working, the wide cladding material is cut into narrow cladding material by the rolling cutting assembly; the axial center distance between the upper forming knife 103 and the lower forming knife 104 is adjusted to two-thirds of the thickness of the cladding material to be pressed, and the narrow cladding material is pressed by the groove forming assembly.

[0031] The substrate blank making device 20 comprises a feed bin 201, a press bin 204, a pinch wheel 202 and a forming die 203. The feed bin 201 is connected to the press bin 204, the pinch wheel 202 is arranged between the output port of the feed bin 201 and the input port of the press bin 204, the granular substrate is squeezed and rubbed by the rotation of the pinch wheel 202, and the forming die 203 is arranged at the output port of the press bin 204 to realize substrate forming and discharging. Figure 3 As shown. When working, the pressing wheel 202 starts to rotate continuously counterclockwise, and the granular substrate enters from the mouth of the feed bin 201, enters the position of the pressing wheel 202 under the action of gravity, and enters the pressing bin 204 under the action of the friction force of the pressing wheel 202. The granular substrate is heated to 500 to 600°C due to friction. Under the dual effects of temperature and pressure, the granular substrate is squeezed to the mouth of the forming mold 203 to realize the substrate forming and discharging. The discharging effect is good, the stability is high, and the operation is convenient.

[0032] The substrate after molding and the covering material after cutting and pressing enter the bimetallic assembly device 30 at the same time, and the substrate is located above the covering material. After passing through the bimetallic assembly device 30, the covering material can cover the substrate to form a bimetallic composite material.

[0033] Furthermore, the bimetallic assembly device 30 comprises a V-shaped composite component, a U-shaped composite component and an O-shaped composite component which are arranged in sequence, and the V-shaped composite component, the U-shaped composite component and the O-shaped composite component cooperate with each other.

[0034] Among them, the above-mentioned V-shaped composite component includes a V-shaped upper roller 301 and a V-shaped lower roller 302 arranged from top to bottom, and the V-shaped upper roller 301 and the V-shaped lower roller 302 cooperate with each other to extrude the substrate and the covering material, so that the covering material is V-shaped and in close contact with the substrate. The above-mentioned U-shaped composite component includes a U-shaped upper roller 303 and a U-shaped lower roller 304 arranged from top to bottom, and the U-shaped upper roller 303 and the U-shaped lower roller 304 cooperate with each other to extrude the substrate and the covering material, so that the covering material is U-shaped and in close contact with the substrate. The above-mentioned O-shaped composite component includes an O-shaped left roller 305 and an O-shaped right roller 306 arranged in sequence, and the O-shaped left roller 305 and the O-shaped right roller 306 cooperate with each other to extrude the substrate and the covering material, so that the covering material is O-shaped and covers the substrate. It can metallurgically bond bimetallic materials, and can continuously produce bimetallic composite wires, with fewer processes and a short production cycle.

[0035] The bimetallic composite material production equipment further comprises a shaping welding assembly 40 and a heating and forming assembly 60 which are arranged in sequence, and the bimetallic composite material can be shaped, welded, heated and formed by the shaping welding assembly 40 and the heating and forming assembly 60 .

[0036] Preferably, the shaping welding assembly 40 comprises a tubular shell 403 and a welding gun 402, a first shaping mold 401 and a second shaping mold 404 located in the tubular shell 403. A feed port and a discharge port are respectively provided on both sides of the tubular shell 403. Among them, the first shaping mold 401 is located at the feed port, the second shaping mold 404 is located at the discharge port, and the welding gun 402 is located in the middle position of the tubular shell 403. The workpiece passes through the first shaping mold 401, the welding gun 402 and the second shaping mold 404 from the feed port in sequence. The function of the first shaping mold 401 is to eliminate the gap between the covering material and the base material, the welding gun 402 welds the covering material into a complete circle, and the function of the second shaping mold 404 is to reduce the diameter of the workpiece by 1mm to 2mm and process the workpiece smoothly. If the base material or the covering material is an easily oxidized material such as titanium alloy, an inert gas such as argon needs to be flushed into the cavity. The bonding force between the bimetallic materials is strong, and the substrate and the covering material are tightly bonded by metallurgical bonding, so the qualified rate of the bimetallic composite materials is higher.

[0037] The above-mentioned heating forming assembly 60 includes sensors and rollers arranged in sequence. The power of the medium frequency heating sensor is 400KW to 600KW, and there are twelve groups of rollers. Along the traveling direction of the bimetallic composite material, the first to sixth groups of rollers are alternately flat rollers and vertical rollers, and the seventh to twelfth groups of rollers are all flat rollers. Along the traveling direction, when the bimetallic composite material passes through the first to sixth groups of rollers, the deformation of the workpiece is 20% to 30% per pass. When passing through the seventh to ninth groups of rollers, the deformation of the workpiece is 10% to 20% per pass (it should be noted that the above twelve groups of rollers are a multi-directional, integral rolling of the bimetallic composite material). When passing through the tenth to twelfth groups of rollers, the workpiece is mainly shaped. During the rolling process of the substrate through the first to ninth groups of rollers, under the dual effects of rolling pressure and temperature, a "pressure forging" welding effect will be generated at the interface, and the metal will produce a new surface at the interface under high pressure and large deformation conditions, achieving metallurgical bonding of metal atoms diffusing each other. If the substrate or cladding material is an easily oxidizable material such as titanium alloy, an inert gas such as argon is required to protect the workpiece surface.

[0038] For example, if stainless steel is used as the base material and carbon steel is used as the cladding material for compounding, the medium frequency heating temperature is controlled to be 1200 to 1400 degrees Celsius, and when passing through twelve sets of rollers, the rolling force is 1200 to 1500KN, and the final overall deformation is 50% to 60%. For example, if TC4 titanium alloy is used as the cladding material and copper is used as the base material for compounding, the medium frequency heating temperature is controlled to be 850 to 940 degrees Celsius, and when passing through twelve sets of rollers, the rolling force is 800 to 1000KN, and the final overall deformation is 50% to 80%.

[0039] This equipment can perform high-efficiency metallurgical compounding of bimetallic materials with high qualified rate, fewer processes and lower processing cost.

[0040] The present invention also discloses a method for producing a bimetallic composite material, which specifically comprises the following steps:

[0041] Step 1: Prepare raw materials and obtain granular substrate and coil-shaped covering material.

[0042] Among them, the preparation of granular substrates; collecting various scraps generated during material processing, sending them to the pickling tank for pickling to remove surface oxide scale, using a dryer to dry, and using a crusher or shredder to break the scraps into 1 to 3 mm granular metal substrates for standby use. Preparation of coiled cladding boards: prepare national standard wide coiled cladding materials, the thickness of which is 1.5 to 2 times the thickness of the finished cladding blank after subsequent processing.

[0043] Step 2: Put the granular substrate obtained in step 1 into the substrate blank making device 20. The substrate blank making device 20 extrude, rub and shape the granular substrate to obtain a substrate blank.

[0044] Specifically, the granular substrate is put into the feed bin 201 of the substrate blank making device 20, and the pressing wheel 202 in the substrate blank making device 20 rotates, and the pressing wheel 202 and the granular substrate in the feed bin 201 rub and squeeze each other. Under the friction and pressure of the pressing wheel 202, the granular substrate is squeezed to the inlet of the forming mold 203 in the substrate blank making device 20, and the overall density is three-fifths to four-fifths of the material density. The inlet of the forming mold 203 forms the granular substrate and discharges the material, and the density of the obtained substrate blank is more than three-quarters of the initial granular substrate.

[0045] Furthermore, the coil-shaped covering material obtained in the above step 1 is put into the covering material blank making device 10, and the coil-shaped covering material passes through the rolling cutting component and the groove forming component in the covering material blank making device 10 in sequence, so as to cut and press the coil-shaped covering material to obtain a covering material blank.

[0046] Specifically, when the cladding blank making device 10 is working, the wide strip-shaped cladding material is cut into narrow strip-shaped cladding material by the rolling cutting assembly, and the positions of the upper roller 101 and the lower roller 102 in the rolling cutting assembly are controlled according to actual needs to adjust the width of the narrow strip-shaped cladding material. The narrow strip is pressed and discharged by the groove forming assembly.

[0047] Step three: placing the above-mentioned substrate blank and cladding material blank into the bimetallic blank assembly device 30 at the same time, wherein the substrate blank is located above the cladding material blank. The bimetallic blank assembly device 30 covers the substrate blank with the cladding material blank to finally form a bimetallic composite material.

[0048] Step 4: The bimetallic composite material obtained in step 3 is sequentially passed through a shaping welding assembly 40 and a heating and forming assembly 60, and the bimetallic composite material is sequentially shaped, welded, heated and formed to obtain a finished bimetallic composite material.

[0049] Among them, the bimetallic composite material is shaped and welded through the shaping welding assembly 40, specifically including: first, the bimetallic composite material enters the tubular shell 403 from the feed port of the tubular shell 403, and the first shaping mold 401 located at the feed port of the tubular shell 403 performs preliminary shaping on the bimetallic composite material. Secondly, the welding gun 402 in the tubular shell 403 welds the bimetallic composite material after preliminary shaping, so that the covering material blank completely covers the substrate blank. Finally, the bimetallic composite material passes through the second shaping mold 404 in the tubular shell 403 again, so that the bimetallic composite material is reshaped, and the bimetallic composite material after reshaping is discharged from the discharge port of the tubular shell 403. When the bimetallic composite material is heated and formed, specifically including: the bimetallic composite material after being processed by the shaping welding assembly 40 is subjected to medium frequency heating, and the power of the medium frequency heating is 400KW to 600KW, to obtain the heated bimetallic composite material. The heated bimetallic composite material is rolled sequentially through twelve groups of rollers, so that the substrate blank and the cladding material blank are tightly combined.
