Description

Technical Field

[0001] This utility model belongs to the technical field of profile processing equipment, and in particular relates to a cold bending forming online photovoltaic steel frame profile 45-degree corner cutting machine. Background Technology

[0002] Profiles are solid straight bars with specific cross-sectional shapes and dimensions, made from metals or composite materials through plastic processing such as rolling and extrusion. Materials include steel, aluminum alloys, and composite materials. They are mainly used in construction, machinery manufacturing, and vehicle lightweighting. Figure 10 The profile shown is an irregular-shaped profile, mainly used for assembling photovoltaic cell frames. Previously, this irregular-shaped profile could be used after being formed by the profile rolling production line and then cut vertically. However, according to customer requirements, the irregular-shaped profile needs to be cut at an angle after forming before being assembled into a cell frame to ensure a more robust assembly. Some manufacturers cut the irregular-shaped profile at an angle with a saw after forming, but the cutting effect is not ideal and the processing efficiency is extremely low. How to quickly cut the irregular-shaped profile at an angle after forming to meet customer needs is an urgent problem to be solved.

[0003] Utility model patent application number CN202222044337.5 discloses a profile cutting mechanism, including a base, a feeding assembly, a cutting assembly, and a discharging assembly. The cutting assembly includes a cutting platform, a support base, a cylinder, a lifting base, and a cutting head. The cutting platform is mounted on the base and has a horizontal U-shaped hole. The U-shaped hole is collinear with the gap between the first and second conveying wheels, allowing the profile to pass through. A cutting hole penetrating the cutting platform is provided in the middle of the U-shaped hole. The support base is mounted on the top of the cutting platform. The cylinder is mounted on the support base and connected to drive the lifting base to move closer to or away from the cutting platform. The cutting head is mounted on the bottom of the lifting base and extends into the cutting hole. The cross-section of the cutting head is the same as that of the cutting hole, allowing the profile to pass through. The extrusion cutting method breaks the profile, and the cut end is consistent with the cross-section of the cutting head. This utility model patent has a feeding component at the front end of the cutting assembly that can adjust the size of the passage space. This not only guides the profile into the cutting assembly, but also reduces the warping of the profile when it is cut, thereby avoiding dimensional deviations at the cut end and resulting in high precision of the processed profile. The cutting platform is split into upper and lower dies, which can improve the processing accuracy of the profile passage channel, thereby further improving the cutting accuracy of the profile. At the same time, it can reduce the processing accuracy of the profile passage channel. However, directly cutting the above-mentioned irregular profiles through the structure of the cutting assembly will cause deformation at the cut end, which cannot meet the customer's usage requirements. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide a cold bending forming online photovoltaic steel frame profile 45-degree corner cutting machine with reasonable structure, no deformation when cutting irregular profiles, and high working efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A cold-bending online photovoltaic steel frame profile 45-degree corner cutting machine includes a profile forming mechanism. A pre-cutting mechanism is provided on one side of the feed end of the profile forming mechanism, and a cutting mechanism is provided on one side of the discharge end of the profile forming mechanism. The pre-cutting mechanism includes a pre-cutting mold, which includes a first upper mold assembly and a first lower mold assembly. The first lower mold assembly includes a pre-cutting lower template and a pre-cutting concave template disposed on the pre-cutting lower template from bottom to top. The first upper mold assembly includes a pre-cutting ejector plate disposed above the pre-cutting concave template, a pre-cutting fixing plate disposed above the pre-cutting ejector plate, and a pre-cutting upper template disposed on the pre-cutting fixing plate from bottom to top. The pre-cutting lower template, the pre-cutting concave template, the pre-cutting fixing plate, and the pre-cutting ejector plate are all provided with a first punching hole and a second punching hole.

[0006] The following are further optimizations of the above technical solution by this utility model: A first punching knife is fixedly connected in the first punching hole of the pre-cutting fixing plate, and a second punching knife is fixedly connected in the second punching hole of the pre-cutting fixing plate. The first punching knife and the second punching knife pass through the first punching hole and the second punching hole of the pre-cutting ejector plate, respectively. When the mold is closed, the end of the first punching knife away from the pre-cutting fixing plate extends into the first punching hole of the pre-cutting concave mold, and the end of the second punching knife away from the pre-cutting fixing plate extends into the second punching hole of the pre-cutting concave mold, thereby achieving the cutting of the first pre-cutting hole and the second pre-cutting hole of the material strip.

[0007] Further optimization: The second punching hole of the pre-cutting lower template, the pre-cutting concave template, the pre-cutting fixing plate, and the pre-cutting ejector plate are all provided with a third punching hole on the side away from the first punching hole.

[0008] Further optimization: A third punching blade is fixedly connected in the third punching hole of the pre-cutting fixing plate. The third punching blade passes through the third punching hole of the pre-cutting ejector plate. When the mold is closed, the end of the third punching blade away from the pre-cutting fixing plate extends into the third punching hole of the pre-cutting concave plate to cut off the positioning hole of the strip.

[0009] Further optimization: The cutting mechanism includes a cutting mold, which includes a second upper mold assembly and a second lower mold assembly.

[0010] Further optimization: The second lower mold assembly includes, from bottom to top, a lower cutting template and a lower cutting concave template disposed on the lower cutting template; the second upper mold assembly includes, from bottom to top, a cutting ejector plate disposed above the lower cutting concave template, a cutting fixing plate disposed above the cutting ejector plate, and an upper cutting template disposed on the cutting fixing plate.

[0011] Further optimization: Cutting holes are provided in the cutting lower template, cutting concave template, cutting fixing plate, and cutting ejector plate.

[0012] Further optimization: A cutting blade is fixedly connected in the cutting hole of the cutting fixing plate. The cutting blade passes through the cutting hole of the cutting ejector plate. When the mold is closed, the end of the cutting blade away from the cutting fixing plate extends into the cutting hole of the cutting concave template, thereby cutting off the side and bottom edges of the profile strip.

[0013] Further optimization: The cutting blade includes a trapezoidal blade section and a rectangular blade section. The trapezoidal blade section is used to cut the side of the profile, and the rectangular blade section is used to cut the bottom of the profile.

[0014] Further optimization: A limiting groove is provided on the side of the cutting concave template close to the cutting ejector plate, and a limiting block is provided on the side of the cutting ejector plate close to the cutting concave template. When the mold is closed, a profile limiting hole is formed between the limiting groove and the limiting block.

[0015] This utility model, through its rational design, pre-cuts the strip with holes before it enters the profile forming mechanism. This allows the strip to form pre-cut grooves at the cut points when it enters the profile forming mechanism to create irregularly shaped profile strips. The cutting mechanism then only cuts the sides and bottom of the profile strip, avoiding the deformation at the first and second pre-cut groove locations that would occur if the cutting mechanism directly cuts the profile strip, thus affecting the quality of the irregularly shaped profile. This meets customer requirements and improves work efficiency.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0019] like Figure 1-10 As shown, a cold-bending online photovoltaic steel frame profile 45-degree corner cutting machine includes a profile forming mechanism 1, a pre-cutting mechanism 2 is provided on one side of the feed end of the profile forming mechanism 1, and a cutting mechanism 3 is provided on one side of the discharge end of the profile forming mechanism 1.

[0020] This design allows the strip 8 to be pre-cut by the pre-cutting mechanism 2 before entering the profile forming mechanism 1. This ensures that when the strip 8 enters the profile forming mechanism 1 to form the profile strip 9, a pre-cut groove is formed at the cut point of the profile strip 9. Then, the cutting mechanism 3 only cuts the profile side 903 and the profile bottom 904 of the profile strip 9. This avoids the deformation at the first pre-cut groove 901 and the second pre-cut groove 902 caused by the cutting mechanism 3 directly cutting the profile strip 9, which would affect the quality of the profile 10 and meet the customer's usage requirements.

[0021] The profile forming mechanism 1 is a profile rolling production line, which can roll the strip 8 into irregular profile strips 9 through multiple rolling units, and is a current technology.

[0022] A feeding mechanism is provided on the side of the pre-cutting mechanism 2 away from the profile forming mechanism 1.

[0023] The pre-cutting mechanism 2 includes a pre-cutting mold, which includes a first upper mold assembly and a first lower mold assembly.

[0024] The pre-cutting mold is installed in the pre-cutting seat, and the pre-cutting seat is equipped with a first driving device that drives the first upper mold assembly to approach or move away from the first lower mold assembly, thereby realizing the pre-cutting of the strip 8.

[0025] The first driving device is a hydraulic cylinder.

[0026] In addition to this embodiment, the first driving device can also be other linear driving devices such as a cylinder.

[0027] The first lower mold assembly includes, from bottom to top, a pre-cutting lower template 201 and a pre-cutting concave template 202 disposed on the pre-cutting lower template 201. The pre-cutting lower template 201 and the pre-cutting concave template 202 are fixedly connected, and the pre-cutting lower template 201 is mounted on the base plate of the pre-cutting seat.

[0028] The first upper mold assembly includes, from bottom to top, a pre-cutting ejector plate 205 disposed above the pre-cutting concave mold plate 202, a pre-cutting fixing plate 204 disposed above the pre-cutting ejector plate 205, and a pre-cutting upper mold plate 203 disposed on the pre-cutting fixing plate 204. The pre-cutting upper mold plate 203 and the pre-cutting fixing plate 204 are fixedly connected, and the pre-cutting upper mold plate 203 is installed on the top plate of the pre-cutting seat.

[0029] A rubber block is provided on the pre-cutting ejector plate 205. The rubber block is placed between the pre-cutting ejector plate 205 and the pre-cutting fixing plate 204 to serve as a buffer.

[0030] The pre-cutting template 201, the pre-cutting concave template 202, the pre-cutting fixing plate 204 and the pre-cutting ejector plate 205 are all provided with a first punching hole 4 and a second punching hole 5, and the first punching hole 4 and the second punching hole 5 on each plate are respectively set accordingly.

[0031] A first punching knife 206 is fixedly connected in the first punching hole 4 of the pre-cutting fixing plate 204. The cross-sectional shape of the first punching knife 206 is the same as that of the first punching hole 4. A second punching knife 207 is fixedly connected in the second punching hole 5 of the pre-cutting fixing plate 204. The cross-sectional shape of the second punching knife 207 is the same as that of the second punching hole 5.

[0032] The first punching blade 206 and the second punching blade 207 pass through the first punching hole 4 and the second punching hole 5 of the pre-cutting ejector plate 205, respectively.

[0033] When the mold is closed, the end of the first punching blade 206 away from the pre-cutting fixing plate 204 extends into the first punching hole 4 of the pre-cutting die plate 202, and the end of the second punching blade 207 away from the pre-cutting fixing plate 204 extends into the second punching hole 5 of the pre-cutting die plate 202, thereby cutting off the first pre-cutting hole 801 and the second pre-cutting hole 802 of the strip 8. The first pre-cutting hole 801 and the second pre-cutting hole 802 are arranged at intervals along the width direction of the strip 8.

[0034] The first pre-cut hole 801 includes a rectangular portion and a first trapezoidal portion.

[0035] The second pre-cut hole 802 includes two second trapezoidal portions.

[0036] With this design, after the strip 8 is rolled into a shaped profile strip 9 by the profile forming mechanism 1, the first pre-cut hole 801 corresponds to the first pre-cut groove 901, wherein the rectangular part corresponds to the rectangular groove of the first pre-cut groove 901, and the first trapezoidal part corresponds to the trapezoidal part of the first pre-cut groove 901; the second pre-cut hole 802 corresponds to the second pre-cut groove 902, so that the cutting position of the shaped profile strip 9 is only connected by the profile side 903 and the profile bottom 904, thereby facilitating the cutting mechanism 3 to cut the shaped profile strip 9 and ensuring that the shaped profile strip 9 will not deform when it is cut. The cutting point forms the tail profile bevel 1001 of the shaped profile 10 and the front profile bevel 1001 of the next section of the shaped profile 10.

[0037] A third punching hole 6 is provided on the side of the second punching hole 5 of the pre-cutting template 201, the pre-cutting concave template 202, the pre-cutting fixing plate 204, and the pre-cutting ejector plate 205 away from the first punching hole 4.

[0038] A third punching blade 208 is fixedly connected inside the third punching hole 6 of the pre-cutting fixing plate 204. The cross-sectional shape of the third punching blade 208 is the same as that of the third punching hole 6.

[0039] The third punching blade 208 passes through the third punching hole 6 of the pre-cutting ejector plate 205.

[0040] When the mold is closed, the end of the third punching cutter 208 away from the pre-cutting fixing plate 204 extends into the third punching hole 6 of the pre-cutting concave template 202 to cut off the positioning hole 803 of the material strip 8.

[0041] With this design, when the irregular profile strip 9 moves to the cutting mechanism 3, the sensor installed on the cutting mechanism 3 detects the shape of the positioning hole 803, ensuring that the pre-cut groove of the irregular profile strip 9 stops at the cutting position of the cutting mechanism 3, thereby achieving accurate cutting of the irregular profile strip 9.

[0042] The cross-sectional shape of the positioning hole 803 is rectangular.

[0043] The pre-cutting mold also includes guide pillars on the lower pre-cutting template 201 and guide sleeves on the upper pre-cutting template 203. The guide pillars and guide sleeves are located in mutually cooperating positions to guide the opening and closing of the pre-cutting mold.

[0044] The cutting mechanism 3 includes a cutting die, which includes a second upper die assembly and a second lower die assembly.

[0045] The cutting mold is tilted, and the cutting mechanism 3 works in conjunction with the profile forming mechanism 1 to facilitate the cutting of the irregular profile strip 9 rolled by the profile forming mechanism 1 at a suitable angle.

[0046] The bottom surface of the cutting mold forms a 45° angle with the horizontal plane.

[0047] The cutting die is installed inside the cutting seat, and the cutting seat is equipped with a second driving device that drives the second upper die assembly to approach or move away from the second lower die assembly, thereby realizing the cutting process of the irregular profile strip 9.

[0048] The second driving device is a hydraulic cylinder.

[0049] In addition to this embodiment, the second drive device can also be other linear drive devices such as cylinders.

[0050] The second lower mold assembly includes, from bottom to top, a cutting lower template 301 and a cutting concave template 302 disposed on the cutting lower template 301. The cutting lower template 301 and the cutting concave template 302 are fixedly connected, and the cutting lower template 301 is mounted on the base plate of the cutting seat.

[0051] The second upper mold assembly includes, from bottom to top, a cutting ejector plate 305 disposed above the cutting concave mold plate 302, a cutting fixing plate 304 disposed above the cutting ejector plate 305, and a cutting upper mold plate 303 disposed on the cutting fixing plate 304. The cutting upper mold plate 303 and the cutting fixing plate 304 are fixedly connected, and the cutting upper mold plate 303 is mounted on the top plate of the cutting seat.

[0052] A rubber block is provided on the cutting and unloading plate 305. The rubber block is placed between the cutting and unloading plate 305 and the cutting and fixing plate 304 to serve as a buffer.

[0053] Cutting holes 7 are provided in the cutting lower template 301, cutting concave template 302, cutting fixing plate 304 and cutting ejector plate 305 respectively, and the cutting holes 7 on each plate are respectively set accordingly.

[0054] A cutting blade 306 is fixedly connected inside the cutting hole 7 of the cutting fixing plate 304. The cross-sectional shape of the cutting blade 306 is the same as that of the cutting hole 7.

[0055] The cutting blade 306 passes through the cutting hole 7 of the cutting and unloading plate 305.

[0056] When the mold is closed, the end of the cutting blade 306 away from the cutting fixing plate 304 extends into the cutting hole 7 of the cutting concave template 302 to cut the profile side 903 and the profile bottom 904 of the profile strip 9.

[0057] The cutting blade 306 includes a trapezoidal blade portion 3061 and a rectangular blade portion 3062.

[0058] With this design, the cutting blade 306 can easily cut the profile side 903 and the profile bottom 904 of the irregular profile strip 9. The trapezoidal blade 3061 cuts the profile side 903, and the rectangular blade 3062 cuts the profile bottom 904, while simultaneously removing the positioning hole 803.

[0059] The included angle α between the two isosceles sides of the trapezoidal blade 3061 is 110.2°±0.5°.

[0060] This design ensures that the angle of the profile bevel 1001 at both ends of the irregular profile 10 is 45°.

[0061] A limiting groove 3021 is provided on the side of the cutting concave template 302 near the cutting ejector plate 305, and a limiting block 3051 is provided on the side of the cutting ejector plate 305 near the cutting concave template 302. When the mold is closed, a profile limiting hole is formed between the limiting groove 3021 and the limiting block 3051. The profile limiting hole accurately positions the irregular profile strip 9, making it convenient for the cutting blade 306 to cut it.

[0062] The cutting mold also includes guide pillars on the lower cutting template 301 and guide sleeves on the upper cutting template 303. The guide pillars and guide sleeves are located in mutually cooperating positions to guide the opening and closing of the cutting mold.

[0063] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
