Description

Technical Field

[0001] The invention relates to the technical field of cupronickel profile processing, and specifically provides a processing method for a U-shaped cupronickel profile. Background Art

[0002] U-shaped nickel-nickel profile is a special metal profile with excellent electrical conductivity, corrosion resistance and wear resistance, and is widely used in the fields of electronics, electrical engineering, and chemical engineering. At present, the processing methods of U-shaped nickel-nickel profile mainly include blank preparation, extrusion molding, heat treatment, surface treatment, cutting verification, and packaging and warehousing. It can be seen that there was no cooling process and straightening process in the previous production and processing process. However, the nickel-nickel profile is affected by high temperature during the extrusion molding process, and thermal stress will be generated inside. If it is not cooled in time, these thermal stresses may cause deformation, cracking, and oxidation discoloration of the profile; at the same time, during the extrusion molding process, due to the unevenness of the mold, the uneven shrinkage of the material, and the inconsistent cooling speed, the nickel-nickel profile produced may bend or twist, making the straightness and geometric dimensions of the nickel-nickel profile not meet the requirements.

[0003] In this regard, the failure rate in subsequent inspections can be reduced through cooling and straightening processes. The cooling process can quickly reduce the temperature of the nickel silver profile, reduce the accumulation of thermal stress, and reduce the probability of oxidation changes. The straightening process can make the straightness and geometric dimensions of the nickel silver profile more in line with the requirements.

[0004] However, if the cooling and straightening processes of the nickel silver profile are carried out separately, the extruded U-shaped nickel silver profile is cooled first, and then the U-shaped nickel silver profile is straightened, the following problems will occur when straightening the cooled U-shaped nickel silver profile: 1. Large internal stresses may accumulate inside the cooled U-shaped nickel silver profile, and these internal stresses are likely to cause deformation or cracking during the straightening process of the U-shaped nickel silver profile, increasing the scrap rate; 2. Straightening is performed after cooling, and the elastic modulus of the cooled U-shaped nickel silver profile increases, and the response to the straightening force is more sensitive. The U-shaped nickel silver profile is prone to rebound, resulting in unstable dimensions after straightening, making it difficult to achieve precise dimensional requirements or requiring multiple reworks to achieve the ideal straightening effect. Summary of the invention

[0005] In view of the above problems, an embodiment of the present application provides a method for processing a U-shaped nickel-nickel profile, which uses a straightening device for a U-shaped nickel-nickel profile to solve the technical problems in the related art.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] See also Figure 2 and Figure 3 A method for processing a U-shaped nickel silver profile uses a straightening device for the U-shaped nickel silver profile. The straightening device for the U-shaped nickel silver profile includes: a base 1, two fixed platforms 2 are installed on the top of the base 1, and a cooling pre-straightening mechanism 4 for cooling and straightening the extruded U-shaped nickel silver profile 6 is installed on the two fixed platforms 2.

[0042] See also Figure 2 Two support platforms 3 are also installed on the top of the base 1, and a roller straightening and shaping mechanism 5 for straightening the inner wall of the U-shaped white copper profile 6 is installed between the two support platforms 3; the cooling pre-straightening mechanism 4 and the roller straightening and shaping mechanism 5 are arranged in sequence along the length direction of the base 1.

[0043] See also Figure 2 , Figure 3 and Figure 7 The cooling pre-straightening mechanism 4 includes a lower abutment guide plate 40 and two straightening guide plates 41. The two straightening guide plates 41 are respectively installed on the opposite surfaces of the two fixed platforms 2 through elastic abutment groups 42. The two straightening guide plates 41 are in an eight-shaped shape with a small diameter facing the support platform 3. The lower abutment guide plate 40 is connected between the tops of the two fixed platforms 2 through an elastic abutment group 43. The lower abutment guide plate 40 is in a structure that gradually tilts downward from the fixed platform 2 to the support platform 3. A blowing cooling group 44 located between the two fixed platforms 2 is installed on the top of the base 1, and supporting components 45 evenly arranged along the length direction of the fixed platform 2 are installed on the blowing cooling group 44.

[0044] The nickel-nickel blank is put into an extrusion die for extrusion molding to obtain a preliminarily formed U-shaped nickel-nickel profile 6. The U-shaped nickel-nickel profile 6 enters between the large-diameter ends of the two straightening guide plates 41. The support assembly 45 supports the horizontal section of the U-shaped nickel-nickel profile. The blowing cooling group 44 blows air to cool the U-shaped nickel-nickel profile 6 during its movement. When the U-shaped nickel-nickel profile 6 is unevenly deformed and bent or twisted, the two straightening guide plates 41 cooperate to straighten the U-shaped nickel-nickel profile 6, thereby improving the straightness of the U-shaped nickel-nickel profile 6. Straightening, and the straightening guide plate 41 contacts the outer wall of the vertical section of the U-shaped nickel-nickel profile 6. When the vertical section of the U-shaped nickel-nickel profile 6 bends and deforms away from the middle, the vertical section of the U-shaped nickel-nickel profile 6 is straightened by the gradually increasing thrust force of the straightening guide plate 41. When the U-shaped nickel-nickel profile 6 is deformed to bulge upward, the U-shaped nickel-nickel profile 6 is gradually deformed downward and straightened under the gradually increasing resistance force of the lower side wall of the lower guide plate 40, thereby achieving straightening of the straightness of the U-shaped nickel-nickel profile 6 and preliminary straightening of the outer wall.

[0045] The elastic force of the elastic push group 42 and the elastic pressure group 43 controls the push force of the guide plate 40 and the straightening guide plate 41 on the U-shaped nickel-nickel alloy profile 6 for straightening, thereby avoiding the problem of reverse deformation or cracking of the U-shaped nickel-nickel alloy profile 6 due to the large push force when the U-shaped nickel-nickel alloy profile 6 is straightened by a one-step push straightening force.

[0046] See also Figure 2 , Figure 4 and Figure 7 The air blowing cooling group 44 includes a C-shaped platform 440 installed on the top of the base 1 and located between two fixed platforms 2. The C-shaped platform 440 is a cavity structure. Multiple supporting components 45 are rotatably connected between two vertical sections of the C-shaped platform 440. The dimension between the two vertical sections of the C-shaped platform 440 is smaller than the dimension between the two vertical sections of the U-shaped white copper profile 6. The top of the vertical section and the horizontal section of the C-shaped platform 440 are both provided with air blowing holes 442, and an air inlet pipe 443 is installed at one end of the C-shaped platform 440.

[0047] The supporting assembly 45 supports the horizontal section of the U-shaped nickel-nickel profile 6, and the external fan delivers air to the U-shaped platform 440 through the air inlet pipe 443. The air source cools the U-shaped nickel-nickel profile 6 through the blowing holes 442. At the same time, the heat absorbed by the supporting assembly 45 on the U-shaped nickel-nickel profile 6 is cooled by the blowing of the blowing holes 442, thereby further improving the cooling uniformity of the U-shaped nickel-nickel profile 6.

[0048] See also Figure 2 and Figure 3 The elastic pressing group 43 includes an I-shaped frame 430 installed on the top of two fixed platforms 2 through supporting legs. The lower end of the I-shaped frame 430 is hinged to the top of the lower resisting guide plate 40 through a lower resisting spring rod 431 evenly arranged along its length direction. The lower resisting guide plate 40 is supported by the elastic force of the lower resisting spring rod 431 to prevent the lower resisting guide plate 40 from rigidly resisting the deformed part of the U-shaped nickel silver profile 6, resulting in a large internal stress inside the material, causing the U-shaped nickel silver profile 6 to deform or crack in subsequent use.

[0049] See also Figure 2 , Figure 3 and Figure 5The elastic push group 42 includes guide strips 420 installed at both ends of the straightening guide plate 41 arranged along its length direction. The guide strips 420 are used to further improve the stability of the movement of the straightening guide plate 41. The guide strips 420 are slidably connected to the corresponding fixed platform 2. The fixed platform 2 is equipped with push spring rods 421 that are evenly arranged along its length direction and in contact with the straightening guide plate 41. The straightening guide plate 41 is supported by the elastic force of the push spring rods 421 to prevent the straightening guide plate 41 from rigidly pushing the vertical section deformation of the U-shaped white copper profile 6. Due to the large push force, the U-shaped white copper profile 6 may be deformed or cracked.

[0050] See also Figure 4 The tops of the two vertical sections of the U-shaped platform 440 are both provided with inclined surfaces, and the blowing holes 442 are evenly arranged along the inclined surfaces, thereby expanding the angle and area of ​​the blowing holes 442 for blowing and cooling the U-shaped white copper profile 6.

[0051] See also Figure 5 , Figure 7 and Figure 8 A gathering groove 410 is provided on the straightening guide plate 41, and blowing holes 442 are also installed near the lower ends of the opposite surfaces of the two straightening guide plates 41, and the blowing holes 442 are connected with the gathering groove 410. The blowing holes 442 on the straightening guide plate 41 are arranged at an angle, and a retractable hose is installed between the bottom of the straightening guide plate 41 and the U-shaped platform 440. Cold air enters the gathering groove 410 through the hose and then cools the U-shaped copper-nickel profile 6 through the blowing holes 442 on the straightening guide plate 41, thereby further improving the uniformity and comprehensiveness of the cooling of the U-shaped copper-nickel profile 6.

[0052] See also Figure 4 and Figure 7 The supporting assembly 45 is composed of a rotating shaft 450 and a supporting roller 451 connected to the rotating shaft 450 by a spline fit and sliding along its axial direction, and both ends of the supporting roller 451 are arc-shaped structures. When the bent or twisted part of the U-shaped nickel-nickel profile 6 moves onto the supporting roller 451, the supporting roller 451 moves axially along the rotating shaft 450 according to the bending deformation direction of the U-shaped nickel-nickel profile 6, so that the supporting roller 451 can always support the lower end surface of the horizontal section of the U-shaped nickel-nickel profile 6 and cooperate with the straightening guide plate 41.

[0053] See also Figure 2 , Figure 3 , Figure 5 and Figure 6The roller straightening and shaping mechanism 5 includes a pressing roller 50 that is rotatably connected between two support platforms 3 and is evenly arranged along the length direction thereof. An internal straightening component 51 is also installed between the two support platforms 3. The pressing roller 50 is used to press and limit the top of the U-shaped nickel silver profile 6 and the back surfaces of the two vertical sections after straightening. Multiple pressing rollers 50 cooperate with the internal straightening component 51 to straighten the inner wall of the U-shaped nickel silver profile 6. A rotating drive group that drives multiple pressing rollers 50 to rotate in coordination with the internal straightening component 51 is installed on one of the support platforms 3, and a transition component 52 is commonly installed at one end of the two support platforms 3 close to the fixed platform 2.

[0054] After the outer wall of the U-shaped nickel silver profile 6 is straightened, when the U-shaped nickel silver profile 6 enters the roller straightening and shaping mechanism 5 through the transition component 52, the pressing roller 50 presses and limits the top of the straightened U-shaped nickel silver profile 6 and the back sides of the two vertical sections. The inner straightening component 51 cooperates with the pressing roller 50 under the driving action of the rotating drive group to gradually roller straighten the inner wall of the U-shaped nickel silver profile 6.

[0055] By cooperating with the cooling pre-straightening mechanism 4 and the roller straightening and shaping mechanism 5, the U-shaped nickel-nickel profile 6 after extrusion forming is straightened while being cooled. In the process of gradually decreasing the temperature of the U-shaped nickel-nickel profile 6, the shape is gradually adjusted to ensure the straightness and dimensional accuracy of the profile. At the same time, the straightening accuracy of the U-shaped nickel-nickel profile 6 is also improved, and the one-time forming of the U-shaped nickel-nickel profile 6 is realized, the number of rework times is reduced, and the production efficiency is improved.

[0056] See also Figure 5 , Figure 6 and Figure 7 The inner straightening assembly 51 includes inner straightening rollers 510 rotatably connected between the two support platforms 3 and evenly arranged along the length direction thereof. The inner straightening rollers 510 correspond to the pressing rollers 50 one by one. Except for the inner straightening rollers 510 connected to the side of the support platform 3 away from the fixed platform 2, both ends of the other inner straightening rollers 510 are conical in shape, and the conical slopes of the multiple inner straightening rollers 510 decrease successively toward the side away from the fixed platform 2.

[0057] When the U-shaped nickel-nickel alloy profile 6 enters between the inner straightening roller 510 and the pressing roller 50 from the transition assembly 52, the inner straightening roller 510 and the horizontal section of the pressing roller 50 roll-straighten the horizontal section of the U-shaped nickel-nickel alloy profile 6, and the end conical surfaces of the multiple inner straightening rollers 510 gradually straighten the inwardly protruding part of the vertical section of the U-shaped nickel-nickel alloy profile 6 during the rotation process, thereby achieving the straightening of the inner side wall of the U-shaped nickel-nickel alloy profile 6.

[0058] The rotary drive group includes a gear group fixedly mounted on the inner straightening roller 510 and meshing with the end of the pressure roller 50, and multiple pressure rollers 50 are connected by sprocket chain transmission. One of the pressure rollers 50 is connected to an external drive motor after passing through the support platform 3 (the rotary drive group is not fully shown in the figure), so that when the inner straightening roller 510 cooperates with the pressure roller 50, it can not only straighten the U-shaped white copper profile 6, but also transport it.

[0059] See also Figure 3 The pressing roller 50 is in an H-shaped structure. The horizontal section of the pressing roller 50 is used to limit the top of the vertical section of the U-shaped nickel-nickel alloy profile 6 after correction. The vertical section of the pressing roller 50 is used to limit the back sides of the two vertical sections of the U-shaped nickel-nickel alloy profile 6 after correction, so that the pressing roller 50 and the inner straightening roller 510 can cooperate to straighten the inwardly inclined part of the U-shaped nickel-nickel alloy profile 6.

[0060] See also Figure 3 and Figure 5 The transition assembly 52 is composed of an inverted clamping plate 520 installed between two support platforms 3 through a hanging plate 521. The inverted clamping plate 520 is used to limit the outer wall of the U-shaped nickel silver profile 6 so that the U-shaped nickel silver profile 6 after preliminary straightening can smoothly enter between the pressure roller 50 and the inner straightening roller 510.

[0061] See also Figure 1 The specific method for processing the U-shaped nickel-nickel profile 6 using the above-mentioned U-shaped nickel-nickel profile straightening equipment includes the following steps: S1, blank preparation: select the nickel-nickel blank that meets the requirements and perform preliminary processing to make the size and shape meet the subsequent processing requirements.

[0062] S2, extrusion molding: placing the nickel silver blank into an extrusion die for extrusion molding to obtain a preliminarily formed U-shaped nickel silver profile 6.

[0063] S3, cooling and straightening: the U-shaped cupronickel profile 6 after extrusion is put into the straightening equipment, and the cooling pre-straightening mechanism 4 cooperates with the roller straightening and shaping mechanism 5 to straighten the U-shaped cupronickel profile 6 after extrusion, so that the U-shaped cupronickel profile 6 gradually adjusts its shape in the process of gradually decreasing temperature, thereby ensuring the straightness and dimensional accuracy of the U-shaped cupronickel profile 6.

[0064] S4. Heat treatment: heat treatment is performed on the profile after cooling and straightening.

[0065] S5. Surface treatment: The U-shaped cupronickel profile 6 after heat treatment is surface treated by mechanical polishing or chemical polishing, and a protective layer is plated on the surface of the profile to enhance the corrosion resistance and decorative effect of the profile.

[0066] S6, cutting inspection: Cut the surface treated U-shaped cupronickel profile 6 into required lengths to obtain the required U-shaped cupronickel profile 6, and inspect the appearance, size and mechanical properties of the U-shaped cupronickel profile 6 to ensure that the quality of the U-shaped cupronickel profile 6 meets the standards.
