Description

Technical Field

[0001] This invention relates to the field of copper pipe bending technology, and in particular to a copper pipe bending embossing machine. Background Technology

[0002] Copper pipe, also known as red copper pipe, is a type of non-ferrous metal pipe, consisting of seamless pressed and drawn tubing. Copper pipe possesses excellent electrical and thermal conductivity, making it a primary material for conductive and heat dissipation components in electronic products. It has become the preferred choice for modern contractors installing water supply, heating, and cooling pipes in all residential and commercial buildings. Copper pipe has strong corrosion resistance, is not easily oxidized, does not readily react chemically with some liquids, and is easily bent and shaped.

[0003] In the traditional process of adding raised dots to copper bends, the curved shape of the copper bend makes it difficult to fix, which is not conducive to the work. In the current technology, the fixing and positioning of the copper bend is done manually. The manual operation is cumbersome, time-consuming and labor-intensive, increasing the workload of the workers and easily causing positioning deviation during the adding of raised dots. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a copper pipe bending and embossing machine.

[0005] This invention is achieved through the following technical solution:

[0006] A copper pipe bending and embossing machine includes a vibratory plate, a material handling robot with upper and lower cylinders, a material handling and removal cylinder, a product clamping cylinder, a product feeding cylinder, a product embossing clamping and positioning cylinder, an embossing servo motor, and a material removal cylinder.

[0007] The vibratory feeder is provided with a receiving platform for receiving copper bends at the discharge end. The upper and lower cylinders of the picking robot are installed at the moving end of the picking and removing cylinder, and a picking robot is installed at the lower end of the upper and lower cylinders of the picking robot.

[0008] The product clamping cylinder is mounted on a sliding guide rail. The product feeding cylinder drives the product clamping cylinder to slide back and forth on the sliding guide rail. An upper pressure block is installed on the moving end of the product clamping cylinder, and a lower pressure block corresponding to the upper pressure block is installed on the mounting seat of the product clamping cylinder.

[0009] A mounting plate is installed in front of the product clamping cylinder. A through hole is opened on the mounting plate. A hollow expansion mandrel is installed on the rear side of the mounting plate at the position corresponding to the through hole. Protrusions are provided on two opposite surfaces of the protrusion end of the expansion mandrel.

[0010] The servo motor for making bumps is connected to a top shaft via a lead screw. The servo motor drives the top shaft to pass through the through hole on the mounting plate and extend into the expansion mandrel.

[0011] The product protrusion clamping and positioning cylinder has two parts, which are respectively installed on the left and right sides of the expansion mandrel. Clamping blocks with arc-shaped grooves are respectively installed on the moving ends of the two product protrusion clamping and positioning cylinders.

[0012] The stripping cylinder is mounted on the mounting plate, and a stripping plate is mounted on the moving end of the stripping cylinder. A through hole is opened on the stripping plate, and the stripping plate is sleeved on the outside of the expansion mandrel through the through hole.

[0013] The copper bend is vibrated onto the receiving platform by a vibratory feeder. The lifting robot's upper and lower cylinders move it downwards to grab the copper bend. The lifting robot's upper and lower cylinders then reset. The material removal cylinder moves the lifting robot above the lower pressure block. The lifting robot's upper and lower cylinders move it downwards to place the copper bend onto the lower pressure block, with the end of the copper bend to be stamped extending in front of the lower pressure block. The lifting robot's upper and lower cylinders and the material removal cylinder reset. The product clamping cylinder moves the lower pressure block to press the other end of the copper bend tightly. The product feeding cylinder then... The copper bend moves forward, and the end of the copper bend to be embossed is fitted onto the expansion mandrel. The two product embossing clamping and positioning cylinders drive the two clamping blocks to clamp the rear part of the end of the copper bend to be embossed. The product clamping cylinder and the product feeding cylinder reset. At the same time, the embossing servo motor drives the top shaft to extend into the expansion mandrel, causing the expansion mandrel to open. The embossing is then applied to the copper bend through the embossing on the expansion mandrel. The embossing servo motor and the product embossing clamping and positioning cylinder reset. The stripping cylinder drives the stripping plate to move, causing the embossed copper bend to exit the expansion mandrel.

[0014] The receiving platform has a receiving groove that connects to the discharge end of the vibratory feeder. The shape of the receiving groove corresponds to that of the copper bend. On both sides of the receiving groove, there are interconnected robotic arm clearance grooves.

[0015] The material handling robot is a two-claw robot driven by a cylinder.

[0016] The pressing block is fixed to the side of the product clamping cylinder mounting base, and a fan-shaped groove for placing copper bends is opened on the pressing block.

[0017] The mounting plate is a U-shaped plate, and two product-mounted clamping and positioning cylinders are respectively installed on the two side plates of the U-shaped plate.

[0018] The fixed end of the expansion mandrel is fixed to the mounting plate by a hollow fixing seat; an axial notch is opened in the middle of the expansion mandrel to divide the expansion mandrel into upper and lower parts, and two protrusions are respectively set on the outer surface of the protrusion end of the upper and lower parts.

[0019] The end of the top shaft is tapered.

[0020] The advantages of this invention are: This invention uses a vibratory feeder, a robotic arm with upper and lower cylinders, a material removal cylinder, a product clamping cylinder, a product feeding cylinder, a product embossing clamping and positioning cylinder, an embossing servo motor, and a stripping cylinder to sequentially complete the entire process of conveying, gripping, removing, clamping, feeding, clamping and positioning, embossing with the expansion mandrel, and stripping of the copper bend. The entire process can be controlled by a single control device, achieving automation by having one person operate multiple devices, improving production efficiency, reducing labor costs, and solving the problem of directional deviation of the product during the embossing process.

[0032] like Figure 1-7 As shown, a copper pipe bending and embossing machine includes a vibratory plate 1, a material handling robot upper and lower cylinder 2, a material handling and removal cylinder 3, a product clamping cylinder 4, a product feeding cylinder 5, a product embossing clamping and positioning cylinder 6, an embossing servo motor 7, and a material removal cylinder 8.

[0033] A receiving platform 9 for catching copper bends is provided at the discharge end of the vibratory feeder 1. The upper and lower cylinders 2 of the picking robot are installed at the moving end of the picking and removing cylinder 3. A picking robot 10 is installed at the lower end of the upper and lower cylinders 2. The picking robot 10 is a two-claw robot driven by a cylinder. Figure 10 As shown, a receiving groove 11 is provided on the receiving platform 9 to connect with the discharge end of the vibratory feeder 1. The shape of the receiving groove 11 corresponds to that of the copper bent tube 20. Interconnected robotic arm clearance grooves 12 are provided on both sides of the receiving groove 11. The copper bent tube exiting the vibratory feeder 1 directly enters the receiving groove 11, thus determining the placement direction of the copper bent tube 20. The robotic arm clearance grooves 12 facilitate material handling by the robotic arm without changing the orientation of the copper bent tube, allowing it to be correctly placed onto the pressing block in the subsequent process.

[0034] The product clamping cylinder 4 is mounted on the sliding guide rail 13. The product feeding cylinder 5 drives the product clamping cylinder 4 to slide back and forth on the sliding guide rail 13. An upper pressure block 14 is fixed at the moving end of the product clamping cylinder 4. A lower pressure block 15 corresponding to the upper pressure block 14 is mounted on the mounting base of the product clamping cylinder 4. The lower pressure block 15 is fixed on the side of the mounting base of the product clamping cylinder 4. A fan-shaped groove 16 for placing copper bends is opened on the lower pressure block 15. The material handling robot puts the copper bends into the fan-shaped groove 16, keeping the direction of the copper bends unchanged to prevent subsequent positioning deviation.

[0035] A mounting plate 17 is fixed in front of the product clamping cylinder 4. A through hole is opened on the mounting plate 17. A hollow expansion mandrel 18 is fixed on the rear side of the mounting plate 17 at the position corresponding to the through hole. A protrusion 19 is provided on two opposite surfaces of the protrusion end of the expansion mandrel 18.

[0036] like Figure 8 As shown, the fixed end of the expansion mandrel 18 is fixed to the mounting plate 17 by a hollow fixing seat; an axial notch 21 is opened in the axial middle of the expansion mandrel 18, dividing the expansion mandrel 18 into upper and lower parts, and two protrusions 19 are respectively provided on the outer surface of the protrusion end of the upper and lower parts.

[0037] like Figure 9As shown, the servo motor 7 for creating raised dots is connected to a top shaft 22 via a lead screw, and the end of the top shaft 22 is tapered. The servo motor 7 drives the top shaft to pass through the through hole in the mounting plate and extend into the expansion mandrel 18. When the top shaft 22 is not inserted into the expansion mandrel 18, the upper and lower parts of the expansion mandrel 18 are close to each other. When the top shaft 22 is inserted into the expansion mandrel 18, under the action of the top shaft 22, the upper and lower parts of the expansion mandrel 18 are pushed outward, thereby achieving the purpose of creating raised dots.

[0038] The product protrusion clamping and positioning cylinder 6 has two parts, which are respectively installed on the left and right sides of the expanding mandrel 18. Clamping blocks 23 with arc-shaped grooves are fixed to the moving ends of the two product protrusion clamping and positioning cylinders 6. The mounting plate 17 is a U-shaped plate, and the two product protrusion clamping and positioning cylinders 6 are respectively installed on the two side plates of the U-shaped plate. The clamping and positioning are precise and will not deviate.

[0039] The stripping cylinder 8 is mounted on the mounting plate 17. A stripping plate 24 is fixed on the moving end of the stripping cylinder 8. A through hole is opened on the stripping plate 24, and the stripping plate 24 is sleeved on the outside of the expanding mandrel 18 through the through hole.

[0040] The copper bend 20 is vibrated by the vibrating plate 1 into the receiving groove 11 of the receiving platform 9. The lifting robot cylinder 2 drives the lifting robot 10 to move downwards to grab the copper bend 20. The lifting robot cylinder 2 resets. The material removal cylinder 3 drives the lifting robot 10 to move above the lower pressure block 15. The lifting robot cylinder 2 drives the lifting robot 10 to move downwards to place the copper bend 20 into the fan-shaped groove of the lower pressure block 15. The end of the copper bend to be stamped extends to the front of the lower pressure block. The lifting robot cylinder 2 and the material removal cylinder 3 reset. The product clamping cylinder 4 drives the lower pressure block to press the other end of the copper bend. Feeding cylinder 5 drives the copper bend tube forward. The end of the copper bend tube to be embossed is fitted onto the expansion mandrel. Two product embossing clamping and positioning cylinders 6 drive two clamping blocks to clamp the rear part of the end of the copper bend tube to be embossed. The product clamping cylinder 4 and the product feeding cylinder 5 reset. At the same time, the embossing servo motor 7 drives the top shaft to extend into the expansion mandrel, causing the expansion mandrel to open. The embossing is then applied to the copper bend tube 20 through the embossing on the expansion mandrel 18. The embossing servo motor 7 and the product embossing clamping and positioning cylinder 6 reset. The unloading cylinder 8 drives the unloading plate to move, causing the embossed copper bend tube to exit the expansion mandrel 18 and fall into the collection device below.

[0041] This invention mainly uses a PLC system to control various cylinders and motors to complete the automatic feeding, clamping, bumping, and unloading processes of copper bends. It transforms the original single-person operation into one person operating multiple machines, improving production efficiency, reducing labor costs, and solving the positioning deviation problem of the product during the bumping process.
