Description

Technical Field

[0001] This utility model relates to the field of hardware product manufacturing technology, specifically to a pipe bending and cutting device for hardware product manufacturing. Background Technology

[0002] A pipe bending and cutting machine for hardware product manufacturing is a modern CNC machine tool that integrates automatic feeding, high-precision bending, and high-speed cutting. It is specifically designed for the complex processing of various metal pipes (such as stainless steel pipes, carbon steel pipes, aluminum pipes, and copper pipes) in the hardware manufacturing industry. It aims to significantly improve production efficiency and processing accuracy through highly automated and intelligent production methods, reducing reliance on skilled workers and production costs. It is an ideal processing equipment for industries such as bathroom fixtures, furniture, fitness equipment, automotive exhaust pipes, and handrails. However, existing pipe bending and cutting machines for hardware product manufacturing still have certain shortcomings. While traditional pipe bending and cutting equipment for hardware manufacturing can be used effectively, traditional clamps are designed for straight pipes or regular shapes. When used to fix bent pipes, there are few contact points, uneven force distribution, and insufficient clamping force. Under cutting vibration, the pipe fittings are prone to loosening, rotating, or bouncing, leading to inaccurate cutting dimensions and even safety accidents. Furthermore, traditional rigid clamps easily leave indentations and scratches on the surface of hardware pipe fittings, affecting the product's appearance and quality, resulting in scrap, which often troubles users.

[0015] The second clamping mechanism 4 includes a second bidirectional lead screw 401, a second sprocket 402, a second chain 403, a slider 404, a support plate 405, a fixing plate 406, a clamping plate 407, a slide rail 408, a second slide rod 409, a second spring 410, and a second roller 411. Two sets of second clamping mechanisms 4 are provided on the support frame 1. The two sets of second clamping mechanisms 4 are staggered and connected by the second sprocket 402 and the second chain 403. The second bidirectional lead screw 401 is connected to the support frame 1 by a bearing. The second sprocket 402 is threaded onto the second bidirectional lead screw 401. The second chain 403 is engaged on the second sprocket 402.

[0016] The second bidirectional lead screw 401 is threadedly connected to a slider 404, a support plate 405 is fixedly installed on the slider 404, a fixing plate 406 is fixedly installed on the support plate 405, a clamping plate 407 is hinged on the fixing plate 406, a slide rail 408 is fixedly installed on the fixing plate 406, and the slide rail 408 is connected to the clamping plate 407 by fixing bolts.

[0018] The cutting device 3 includes a fixed frame 301, a multi-stage hydraulic cylinder 302, a sliding plate 303, a drive motor 304, and a cutting blade 305. The fixed frame 301 is fixedly installed on the support frame 1. The multi-stage hydraulic cylinder 302 is fixedly installed on the fixed frame 301. The sliding plate 303 is fixedly installed at the output end of the multi-stage hydraulic cylinder 302.

[0019] The slide plate 303 is slidably connected to the support frame 1. A drive motor 304 is fixedly installed on the left side of the slide plate 303, and a cutting blade 305 is fixedly installed at the output end of the drive motor 304.

[0020] Working principle: When using a pipe bending and cutting equipment for manufacturing hardware products, the pipe to be processed is first placed on the support frame 1, so that it passes between the two sets of first rollers 206 of the first clamping mechanism 2 and extends to the clamping area of ​​the second clamping mechanism 4. The first clamping mechanism 2 is activated: the drive motor 201 operates, driving the first bidirectional lead screw 202 to rotate. The rotation of the first bidirectional lead screw 202 causes the two sets of connecting frames 203 to move towards or away from each other, thereby driving the first slide bar 204 and the first roller 206 to move, clamping or releasing the bent pipe from the vertical direction. The first spring 205 provides elastic cushioning to prevent overpressure damage to the pipe surface, while ensuring adaptive clamping for different pipe diameters; Subsequently, the first sprocket 208 and the first chain 209 drive the second clamping mechanism 4, which in turn rotates the second bidirectional lead screw 401, causing the slider 404 on it to move. The slider 404, through the support plate 405 and the fixing plate 406, drives the hinged clamping plate 407 to rotate around the hinge point. Constrained by the slide rail 408, it achieves a clamping clamping effect on the other end of the bent pipe. Under the action of the second spring 410, the four sets of second slide rods 409 and the second roller 411 on the clamping plate 407 can adapt to the irregular curved surface of the bent pipe, achieving multi-point elastic contact and providing stable and damage-free fixation. After the bent pipe is securely clamped by the first clamping mechanism 2 and the second clamping mechanism 4, the cutting device 3 is started. The drive motor 304 starts, driving the cutting blade 305 to rotate at high speed. The multi-stage hydraulic cylinder 302 works, and its output end pushes the slide plate 303 to smoothly feed towards the bent pipe along the support frame 1. The drive motor 304 and the cutting blade 305 on the slide plate 303 move forward synchronously. The high-speed rotating cutting blade 305 contacts the bent pipe and completes the cutting operation. The multi-stage hydraulic cylinder 302 can provide a stable and powerful feed force, ensuring cutting efficiency and quality, thereby completing a series of tasks.
