Description

Technical Field

[0001] The present invention relates to the technical field of faucet processing equipment, and in particular to a faucet elbow pipe processing equipment. Background Art

[0002] A faucet is a common name for a water valve, which is used to control the size of the water flow switch and has the effect of saving water. The replacement speed of faucets is very fast. It has developed from the old cast iron process to the electroplated knob type, and then to the stainless steel single-temperature single-control faucet, stainless steel double-temperature double-control faucet, and kitchen semi-automatic faucet. Now, more and more consumers will comprehensively consider various aspects such as material, function, and shape when choosing a faucet. Therefore, the processing requirements for faucet pipe fittings are becoming more and more stringent, especially for the processing of faucet elbow pipes, and the precision requirements are higher.

[0003] The Chinese Patent Publication No. is CN208116468U, and the bending mechanism of a pipe bender disclosed in the authorization announcement date of November 20, 2018. The bending mechanism is installed on the machine tool 1. The pipe fitting is inserted on the pipe placing mechanism 7 on the machine tool 1. The driving mechanism 4 drives the slider 5 to move towards the direction close to the pipe bending die 31 so that the pipe fitting is clamped between the clamping part 6 and the convex block 32. The driving mechanism 4 on the rotating frame 23 rotates together with the clamping part 6 and the pipe bending assembly 3. During the rotation process, the pipe fitting moves in the extending direction of the pipe placing mechanism 7 towards the pipe bending die 31, and the pipe fitting rotates and bends along with the pipe bending groove 301; after the pipe fitting is bent, the slider 5 retreats from the pipe bending assembly 3 to the initial position through the driving mechanism 4, so that the clamping part 6 and the convex block 32 are separated, and the bent pipe fitting is taken off. The driving mechanism 4 on the rotating frame 23 and the slider 5 rotate together with the pipe bending assembly 3 and return to the initial position.

[0004] Combined with the attached drawings, the deficiencies of the above patent are that the pipe fitting is only inserted on the pipe placing mechanism on the machine tool. When one end of the pipe fitting is bent, on the one hand, it is easy for the rest of the pipe fitting to be deformed; on the other hand, during the bending process, since the pipe fitting moves in the extending direction of the pipe placing mechanism towards the pipe bending die, a large friction is generated between the pipe fitting and the pipe placing mechanism, resulting in wear on the surface of the pipe fitting and reducing the dimensional accuracy of the pipe fitting. Summary of the Invention

[0005] The present invention is to overcome the deficiency that the dimensional accuracy of faucet pipe fittings is easily reduced during the bending process in the prior art, and provides a faucet elbow pipe processing equipment that can improve the dimensional accuracy.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A faucet elbow processing device, which comprises a truss, a material bin, a first machine tool, a bending machine, a cutting and shaping machine and a second machine tool. A manipulator is arranged on the truss, and the manipulator is slidably connected with the truss. The material bin, the first machine tool, the bending machine, the cutting and shaping machine and the second machine tool are arranged in sequence along the sliding direction of the manipulator. The bending machine comprises a limiting member and a bending member. The limiting member is located on the side of the bending member. The limiting member comprises a first workbench and an oil barrel. The oil barrels are respectively located on the sides of the first workbench and the bending member. A limiting portion is arranged on the first workbench. A conveying pipe is arranged on the oil barrel. The oil barrel is connected with the limiting portion through the conveying pipe. An oil pump is detachably installed on the conveying pipe. The bending member comprises a second workbench and a driving motor. A clamping portion which is on the same straight line as the limiting portion is arranged on the second workbench. The driving motor is located at the end of the second workbench. The second workbench rotates around one of its ends under the drive of the driving motor.

[0008] A manipulator is arranged on the truss, and the manipulator is slidably connected with the truss. The material bin, the first machine tool, the bending machine, the cutting and shaping machine and the second machine tool are arranged in sequence along the sliding direction of the manipulator. The bending machine comprises a limiting member and a bending member. The limiting member is located on the side of the bending member. The limiting member comprises a first workbench and an oil barrel. The oil barrels are respectively located on the sides of the first workbench and the bending member. A limiting portion is arranged on the first workbench. A conveying pipe is arranged on the oil barrel. The oil barrel is connected with the limiting portion through the conveying pipe. An oil pump is detachably installed on the conveying pipe. The bending member comprises a second workbench and a driving motor. A clamping portion which is on the same straight line as the limiting portion is arranged on the second workbench. The driving motor is located at the end of the second workbench. The second workbench rotates around one of its ends under the drive of the driving motor. The material bin is used for storing the pipe fittings to be processed, which is convenient for the manipulator to grab; the manipulator is used for conveying the pipe fittings between various devices, realizing the whole production line operation of processing the faucet elbow by the manipulator, which is beneficial to improving the work efficiency and reducing the potential safety hazards of the operation; the first machine tool is convenient for processing the inlet thread at one end of the pipe fitting; after the inlet thread is processed, the bending machine bends the other end of the pipe fitting. One end of the pipe fitting is limited in the limiting portion, and the other end of the pipe fitting is positioned by the clamping of the clamping portion. Then, under the action of the oil pump, the oil in the oil barrel is conveyed through the conveying pipe into the limiting portion and sprayed on the surface of the pipe fitting. The driving motor drives the second workbench and the clamping portion on the second workbench to rotate together. During the rotation, one end of the pipe fitting moves towards the side where the bending member is located. During this movement, due to the lubricating effect of the oil, the wear degree of the surface of the pipe fitting is reduced, achieving the purpose of improving the dimensional accuracy. The other end of the pipe fitting is bent under the clamping action of the clamping portion; since the other end of the pipe fitting will be deformed under the clamping force of the clamping portion, after the pipe fitting is bent, the cutting and shaping machine cuts the part of the pipe fitting clamped by the clamping portion and shapes the cut part, so as to facilitate the second machine tool to process the outlet thread.

[0009] Preferably, the limiting part includes a first slider and a left limiting block. A first cylinder is detachably installed on the first workbench. The first cylinder is located on one side of the first slider. The first slider is slidably connected to the left limiting block and the first workbench under the drive of the first cylinder. On the other side corresponding to the first slider, there is a right limiting block corresponding to the left limiting block. One side of the right limiting block is detachably connected to the first slider. On the other side corresponding to the right limiting block, there is a first arc-shaped limiting groove. On one side of the left limiting block, there is a second arc-shaped limiting groove corresponding to the first arc-shaped limiting groove. Oil cavities are provided inside both the left limiting block and the right limiting block. The oil barrel is connected to the other side corresponding to the left limiting block through a delivery pipe and is communicated with the oil cavity inside the left limiting block. A number of spray holes communicated with the oil cavity are provided inside both the first arc-shaped limiting groove and the second arc-shaped limiting groove. On the side of the right limiting block provided with the first arc-shaped limiting groove, there are a number of first through holes. The first through holes are located on the side surface of the first arc-shaped limiting groove and are communicated with the oil cavity. On the side of the left limiting block provided with the second arc-shaped limiting groove, there are a number of second through holes corresponding one by one to the first through holes. The second through holes are located on the side surface of the second arc-shaped limiting groove and are communicated with the oil cavity. The pipe fitting is limited inside the channel formed by the first arc-shaped limiting groove and the second arc-shaped limiting groove under the drive of the first cylinder. Since the contact areas of the first arc-shaped limiting groove and the second arc-shaped limiting groove with the surface of the pipe fitting are relatively large respectively, and since the limiting part and the clamping part are on the same straight line, the pipe fitting always slides linearly along the channel formed by the first arc-shaped limiting groove and the second arc-shaped limiting groove during the bending process and is not prone to deformation. When the pipe fitting is limited inside the channel formed by the first arc-shaped limiting groove and the second arc-shaped limiting groove, the first through holes and the corresponding second through holes are connected, making the oil cavity inside the left limiting block communicated with the oil cavity inside the right limiting block, and enabling the oil inside the oil cavity to be sprayed onto the surface of the pipe fitting through the spray holes. Thus, during the bending movement of the pipe fitting, the grease can be evenly coated on the pipe fitting, greatly reducing the wear degree of the surface of the pipe fitting, and thus being beneficial to further improving the dimensional accuracy of the pipe fitting.

[0010] Preferably, a first avoidance notch is provided on the left limiting block. The first avoidance notch penetrates through the second arc-shaped limiting groove and is communicated with the second arc-shaped limiting groove. A second avoidance notch corresponding to the first avoidance notch is provided on the right limiting block. The second avoidance notch penetrates through the first arc-shaped limiting groove and is communicated with the first arc-shaped limiting groove. Such a design facilitates the manipulator to grab the pipe fitting by extending into the first avoidance notch and the second avoidance notch after the bending is completed, realizing automatic operation.

[0011] Preferably, the clamping part includes a second slider and a left clamping block. A second cylinder is detachably installed on the second workbench. The second cylinder is located on one side of the second slider. The second slider is slidably connected to the left clamping block and the second workbench under the drive of the second cylinder. On the other side corresponding to the second slider, there is a right clamping block corresponding to the left clamping block. One side of the right clamping block is detachably connected to the second slider. On the other side corresponding to the right clamping block, there is a first arc-shaped clamping groove on the same straight line as the first arc-shaped limiting groove. One end of the left clamping block is close to the left limiting block, and the other end of the left clamping block is far from the left limiting block. The shape of the end of the left clamping block close to the left limiting block is arc-shaped. The end of the left limiting block is provided with an arc-shaped groove matching the end of the left clamping block. The left clamping block is provided with a second arc-shaped clamping groove corresponding to the first arc-shaped clamping groove. One side of the left clamping block is close to the right clamping block, and the other side corresponding to the left clamping block is far from the right clamping block. One end of the second arc-shaped clamping groove is located on the side of the left clamping block close to the right clamping block, and the other end of the second arc-shaped clamping groove is located on the side of the left clamping block far from the right clamping block. One end of the second arc-shaped clamping groove uniformly transitions to the other end along the end of the left clamping block close to the left limiting block to form a U-shaped structure. The clamping part is located on the top of the second workbench, and the driving motor is located at the bottom of the second workbench and corresponds to the left clamping block. When the manipulator inserts the pipe fitting into the second arc-shaped limiting groove, it is also inserted into the second arc-shaped clamping groove. The first cylinder and the second cylinder are driven synchronously, so that while one end of the pipe fitting is limited, the other end is also clamped and positioned by the first arc-shaped clamping groove and the second arc-shaped clamping groove. Under the drive of the driving motor, the second workbench rotates, so that the pipe fitting is bent along the bending direction of the second arc-shaped clamping groove, which is beneficial to improving the precision of the bending radius of the pipe fitting; the arc-shaped groove is beneficial to preventing interference between the left clamping block and the seat limiting block when the left clamping block rotates under the drive of the driving motor.

[0012] Preferably, the cutting and shaping machine includes an operation table, on which a lifting table, a cutting device, a shaping device and a blanking port are provided.

Driven by the cylinder three, the positioning block is slidably connected to the operation table and the lifting table respectively relative to the arc-shaped limiting projection. The other side corresponding to the positioning block matches the recessed part of the arc-shaped limiting projection and is provided with a first arc-shaped groove. The recessed part of the arc-shaped limiting projection is provided with a second arc-shaped groove corresponding to the first arc-shaped groove. The shaping device is slidably connected to the operation table along the sliding direction parallel to the positioning block. The blanking port and the cutting device are both located between the shaping device and the lifting table. The blanking port, the shaping device and the cutting device are all located on the same side of the positioning block. The blanking port is located between the positioning block and the cutting device. After bending, the pipe fitting is conveyed to between the arc-shaped limiting projection and the positioning block by a manipulator. Driven by the cylinder three, the bent part of the pipe fitting is limited in the circular space formed by the first arc-shaped groove and the second arc-shaped groove. At this time, the positioning block is located on the lifting table. Since the other end of the first telescopic shaft is slidably connected to one side of the positioning block up and down, the positioning block can rise or fall together with the lifting table, so that the pipe fitting is always in a fixed state, which is convenient for the cutting device to cut the clamped part of the pipe fitting. The waste after cutting is discharged and collected through the blanking port to keep the surface of the operation table clean and tidy. After cutting, the shaping device is used to shape the cut to improve the roundness of the cut, which is convenient for the second machine tool to machine the outlet thread.

[0013] Preferably, the shaping device includes a moving block. One side of the moving block is close to the blanking port, and the other side corresponding to the moving block is far from the blanking port. A shaping component corresponding to the end of the second arc-shaped groove is provided on the side of the moving block close to the blanking port. A cylinder four is detachably installed on the operation table. The output end of the cylinder four is connected to the side of the moving block far from the blanking port. The moving block is slidably connected to the operation table driven by the cylinder four. Such a design is beneficial for the shaping component to approach or move away from the cut of the pipe fitting driven by the cylinder four, which is convenient for the cutting and shaping operations of the pipe fitting.

[0014] Preferably, the shaping component includes a support plate. On the side of the moving block away from the blanking port, a first rotating motor is detachably installed. The output end of the first rotating motor penetrates through the moving block and is connected to one side of the support plate. Driven by the first rotating motor, the support plate is rotatably connected to the moving block. On the corresponding other side of the support plate, an inner wall shaping block is fixed. The bottom of the inner wall shaping block is close to the operation table, and the top of the inner wall shaping block is away from the operation table. The top of the inner wall shaping block is provided with an arc surface, and the center of the arc of the arc surface is located on the central axis of the second arc-shaped groove. Driven by the first rotating motor, the inner wall shaping block makes a circular motion around the center of the arc of the arc surface. The inner wall shaping block is located at the bottom end of the support plate. At the top end of the support plate, a fifth cylinder is detachably installed. On the output end of the fifth cylinder, an outer wall shaping block corresponding to the inner wall shaping block is provided. The top of the outer wall shaping block is an arc-shaped convex surface and is fixedly connected to the output end of the fifth cylinder. The bottom of the outer wall shaping block is an arc-shaped concave surface. The inner wall shaping block is located within the arc-shaped concave surface. The radius of the arc-shaped concave surface is greater than the radius of the arc surface, and the center of the arc of the arc-shaped concave surface coincides with the center of the arc of the arc surface. Since the center of the arc of the arc surface is located on the central axis of the second arc-shaped groove, and at the same time the center of the arc of the arc-shaped concave surface coincides with the center of the arc of the arc surface, when the bent pipe fitting is limited within the circular space formed by the first arc-shaped groove and the second arc-shaped groove, the inner wall shaping block fits with the inner wall of the pipe fitting, and the outer wall shaping block fits with the outer wall of the pipe fitting under the drive of the fifth cylinder. Thus, the inner wall shaping block and the outer wall shaping block jointly clamp the side wall of the pipe fitting, and under the drive of the first rotating motor, the inner wall shaping block and the outer wall shaping block rotate synchronously to achieve shaping of the roundness of the pipe wall.

[0015] Preferably, the cutting device includes a sixth cylinder. The sixth cylinder is detachably connected to the operation table.

On one side of the mounting frame, a second rotating motor is detachably installed. On the corresponding other side of the mounting frame, a connecting rod is provided. The output end of the second rotating motor penetrates through the mounting frame and is fixedly connected to one end of the connecting rod. At the other end of the connecting rod, an electric cutting wheel corresponding to the blanking port is detachably installed. The sixth cylinder enables the electric cutting wheel to move in the vertical direction. At the same time, the second rotating motor enables the electric cutting wheel to rotate under the drive of the connecting rod, avoiding interference with the manipulator during the sliding process of the manipulator, thus facilitating the manipulator to pick up the pipe fitting, and at the same time making adaptive adjustments to different cutting requirements of the pipe fitting, with strong practicability.

[0016] Preferably, a positioning member is provided on the truss. The positioning member is located between the cutting and shaping machine and the second machine tool. The manipulator is slidably connected to the top of the truss. The positioning member is detachably connected to the bottom of the truss. The positioning member is provided with a positioning groove.

The cutting and shaping machine is located on one side of the second machine tool, and a conveyor belt and a blanking frame are provided on the other side of the second machine tool.

The design of the convex plate, the first limiting groove and the second limiting groove is conducive to the pipe fittings being secondarily positioned, so that they can be accurately positioned when being conveyed into the second machine tool by the manipulator, which is beneficial to accurately machining the outlet thread, and at the same time is convenient for counting the pipe fittings. The processed pipe fittings are conveyed into the blanking frame through the conveyor belt, and the operation is convenient and fast.

[0017] Preferably, the manipulator includes a lifting arm and a clamping jaw. The clamping jaw includes a sliding seat. One side of the sliding seat is detachably connected to the lifting arm.
