Description

Technical Field

[0001] This invention relates to the field of faucet cover processing technology, specifically to a non-standard equipment for bending and forming bus-type faucet covers. Background Technology

[0002] Heavy-duty escalators are widely used in high-traffic public transportation venues such as shopping malls, airports, and subway stations. Their escalator head covers, as core decorative and protective components at escalator entrances and exits, not only serve an aesthetic function but also must withstand heavy impacts from pedestrians and luggage over long periods. Therefore, their structural strength, forming precision, and surface quality have much stricter requirements than those for ordinary elevator components. Heavy-duty escalator head covers are mostly made of thick-walled stainless steel or high-strength aluminum alloy sheets, with a continuous and smooth curved surface structure. Bending forming is the core process that determines the final product quality. Dedicated high-precision bending forming equipment is crucial for ensuring the processing quality, production efficiency, and batch consistency of heavy-duty escalator head covers, directly affecting the overall operational safety and service life of the escalator.

[0003] In the existing technology, the bending and forming of heavy-duty escalator faucet cover plates mainly relies on general-purpose bending machines or simple bending machines for processing. The operation process is as follows: First, the two ends of the thick-walled metal plate are clamped on the left and right clamping devices of the equipment. The rotating arm drives one end of the clamping device to rotate around the fixed axis, so that the plate is bonded to the forming mold under the action of pure bending force. The initial arc contour is obtained by relying on the rigid constraint of the mold. After processing, the part is directly unloaded.

[0004] However, existing bending equipment generally lacks a stretching function, and the clamping force distribution of the left and right clamping mechanisms is uneven, resulting in severe elastic rebound after the sheet is bent. The forming arc deviation is large and the consistency is poor. It is also prone to surface wrinkles and stress concentration due to uneven local force, which cannot meet the high precision and high strength requirements of faucet cover plates. Therefore, a non-standard bending forming equipment for bus faucet cover plates is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a non-standard equipment for bending and forming bus-type faucet covers, solving the problem that existing bending equipment lacks an independent axial stretching function, resulting in severe springback and poor forming quality of thick-walled faucet covers.

[0010] Preferably, the telescopic end of the third hydraulic cylinder is fixedly connected to a second clamping seat, the inner wall of the second clamping seat is fixedly connected to a fourth hydraulic cylinder, and the telescopic end of the fourth hydraulic cylinder is fixedly connected to a second clamping plate.

[0013] Preferably, the support mechanism includes a support frame, the top of which is fixedly connected to the bottom right end of the rotating arm, and a support column is fixedly connected to the bottom of the support frame.

[0014] Preferably, the lower end of the support column is rotatably connected to a wheel frame via a bearing, the middle inner wall of the wheel frame is rotatably connected to a guide wheel via a bearing, the shaft end of the guide wheel is fixedly connected to a third gear, the front inner wall of the wheel frame is rotatably connected to a first brush roller via a bearing, the shaft end of the first brush roller is fixedly connected to a fourth gear, and the outer wall of the fourth gear meshes with the outer wall of the third gear.

[0016] This invention provides a non-standard bending forming equipment for bus-type faucet covers. It has the following beneficial effects: 1. This invention achieves integrated bending and forming of thick-walled faucet cover plates by coordinating the left and right clamping mechanisms and synchronous axial stretching, combined with the high-precision bending action of the rotating mechanism and the pushing action of the top block into the mold. This effectively improves the processing efficiency of the plates and the consistency of product forming, and reduces the intensity of manual operation.

[0017] 2. The present invention adopts a closed gear transmission structure for the rotating mechanism, which improves the rotation angle accuracy and running stability of the rotating arm and avoids the forming defects of the sheet metal caused by the shaking or angle deviation of the rotating arm. At the same time, the left and right clamping mechanisms adopt a synchronous tension control method, which can make the thick-walled sheet metal uniformly stressed, effectively eliminate local stress concentration, prevent wrinkles or cracks on the surface of the sheet metal, and ensure the structural strength of the product.

[0018] 3. This invention provides a support mechanism at the bottom of the rotating arm, using guide wheels that roll along the ground rail to provide stable and reliable support for the free end of the rotating arm. This effectively reduces the load on the shaft, prevents deformation of the shaft due to long-term heavy load, and extends the service life of the equipment. At the same time, the rotation of the guide wheels drives the front and rear sets of brush rollers to rotate synchronously, which can automatically clean metal debris, dust and other foreign objects from the surface of the ground rail. This avoids uneven force and operational instability caused by guide wheels getting stuck or jumping due to foreign objects, further ensuring the rotation accuracy of the rotating arm and improving the forming quality and safety of the faucet cover.

Please see the appendix Figure 3 -Appendix Figure 5The rotating mechanism 2 includes a fixed frame 201 and a rotating shaft 204. The fixed frame 201 is fixedly connected to the back of the machine body 1. A motor 202 is fixedly connected to the inner wall of the fixed frame 201.

A second gear 205 is fixedly connected to the outer wall of the lower end of the rotating shaft 204. The outer wall of the first gear 203 meshes with the outer wall of the second gear 205. A rotating arm 206 is fixedly connected to the outer wall of the rotating shaft 204. When the motor 202 is started, it drives the first gear 203 to rotate, thereby driving the second gear 205 to rotate the rotating shaft 204 and the rotating arm 206. The right clamping mechanism 3 includes a first fixed plate 301, which is fixedly connected to the inner wall of the rotating arm 206. A first hydraulic cylinder 302 is fixedly connected to the inner wall of the first fixed plate 301. A first clamping seat 303 is fixedly connected to the left end of the first hydraulic cylinder 302. A second hydraulic cylinder 305 is fixedly connected to the inner wall of the first clamping seat 303. A first clamping plate 306 is fixedly connected to the telescopic end of the second hydraulic cylinder 305. By activating the first hydraulic cylinder 302, the first clamping seat 303 can be moved, thereby stretching the right end of the plate.

[0023] The left end of the first clamping seat 303 is provided with a first placement groove 304. The outer wall of the first clamping plate 306 is slidably connected to the inner wall of the first placement groove 304. After the right end of the plate is placed in the first placement groove 304, the second hydraulic cylinder 305 is activated to move the first clamping plate 306, so that the first clamping plate 306 clamps and fixes the right end of the plate inside the first clamping seat 303.

[0024] A plate frame 7 is fixedly connected to the inner wall of the machine body 1, and a mold fixing base plate 8 is fixedly connected to the upper surface of the plate frame 7. The mold fixing base plate 8 is used for the installation and fixing of the mold.

[0029] Please see the appendix Figure 7 The support mechanism 5 includes a support frame 501, the top of which is fixedly connected to the bottom right end of the rotating arm 206, and the bottom of which is fixedly connected to a support column 502.

[0030] The lower end of the support column 502 is rotatably connected to the wheel frame 503 via a bearing. The inner wall of the middle part of the wheel frame 503 is rotatably connected to the guide wheel 504 via a bearing. The shaft end of the guide wheel 504 is fixedly connected to the third gear 505. The inner wall of the front end of the wheel frame 503 is rotatably connected to the first brush roller 506 via a bearing. The shaft end of the first brush roller 506 is fixedly connected to the fourth gear 507. The outer wall of the fourth gear 507 meshes with the outer wall of the third gear 505. During the rotation of the rotating arm 206, the guide wheel 504 rolls along the upper surface of the ground rail 6, thereby driving the first brush roller 506 to rotate through the third gear 505 and the fourth gear 507, cleaning the movement path of the guide wheel 504, and preventing foreign particles on the ground rail 6 from affecting the stability of the movement of the guide wheel 504.

[0031] The inner rear wall of the wheel frame 503 is rotatably connected to the second brush roller 508 via a bearing. The shaft end of the second brush roller 508 is fixedly connected to the fifth gear 509. The outer wall of the fifth gear 509 meshes with the outer wall of the third gear 505. A protective cover 510 is fixed to the side wall of the wheel frame 503. The bottom of the guide wheel 504 abuts against the upper surface of the ground rail 6. The bottoms of the first brush roller 506 and the second brush roller 508 are in contact with the upper surface of the ground rail 6. During the rotation of the guide wheel 504, the second brush roller 508 is driven to rotate through the third gear 505 and the fifth gear 509 to clean the movement path of the guide wheel 504.

[0032] Working principle: First, the sheet metal is clamped. The left end of the sheet metal to be processed is placed inside the second placement groove 404 of the left clamping mechanism 4. The fourth hydraulic cylinder 405 is activated to drive the second clamping plate 406 to slide along the inner wall of the second placement groove 404, clamping and fixing the left end of the sheet metal inside the second clamping seat 403. The right end of the sheet metal is placed inside the first placement groove 304 of the right clamping mechanism 3. The second hydraulic cylinder 305 is activated to drive the first clamping plate 306 to slide along the inner wall of the first placement groove 304, clamping and fixing the right end of the sheet metal inside the first clamping seat 303. Subsequently, the rotating mechanism 2 is activated for initial bending. The motor 202 is mounted on the back of the machine body 1 via the fixing frame 201. The output end of the motor 202 drives the first gear 203 to rotate, which in turn drives the second gear 205 to rotate synchronously with the rotating shaft 204 through gear meshing. The rotating shaft 204 drives the rotating arm 206 to rotate around the axis of the rotating shaft 204, causing the right clamping mechanism 3 to drive the right end of the plate to rotate synchronously. The plate gradually fits into the forming mold mounted on the mold fixing base plate 8. The mold fixing base plate 8 is fixed to the inner wall of the machine body 1 via the plate frame 7. During the rotation of the rotating arm 206, the support mechanism 5 operates synchronously. The support frame 501 is fixed to the bottom right end of the rotating arm 206 and is connected to the wheel frame 503 via the support column 502. Next, the guide wheel 504 rolls along the upper surface of the ground rail 6, providing stable support for the free end of the rotating arm 206 that bears the load of the plate. When the guide wheel 504 rotates, it drives the third gear 505 at the shaft end to rotate synchronously. Through gear meshing, it drives the fourth gear 507 and the fifth gear 509 to rotate, which in turn drives the first brush roller 506 and the second brush roller 508 to rotate in opposite directions, cleaning foreign objects on the upper surface of the ground rail 6. The protective cover 510 protects the gear transmission structure. When the plate initially fits the mold, the fifth hydraulic cylinder 10 on the front frame 9 is activated to drive the push block 11 to move towards the mold, pushing the plate into the mold to ensure that the plate and the mold surface are completely fitted, eliminating the gap between the plate and the mold. Finally, the first hydraulic cylinder 302 and the third hydraulic cylinder 402 are activated. The first hydraulic cylinder 302 is installed on the inner wall of the rotating arm 206 through the first fixed plate 301, driving the first clamping seat 303 to move axially to stretch the right end of the plate. The third hydraulic cylinder 402 is installed on the inner wall of the machine body 1 through the second fixed plate 401, driving the second clamping seat 403 to move axially to stretch the left end of the plate. This allows the bent plate to fully overcome its large elastic deformation and produce permanent plastic deformation, achieving the forming dimensions required by the drawing, thus completing the bending forming process of the faucet cover plate.
