Description

Technical Field

[0001] This utility model belongs to the field of PVC pipe technology, specifically relating to an automatic flaring and forming device for PVC pipes. Background Technology

[0002] PVC, primarily composed of polyvinyl chloride, is a material with other components added to enhance its heat resistance, toughness, and ductility. The outermost layer of this surface film is paint, the middle layer is mainly polyvinyl chloride, and the bottom layer is a backing adhesive. Rigid PVC pipes are made by hot-pressing polyvinyl chloride resin with stabilizers, lubricants, etc., and were among the earliest plastic pipes developed and applied. PVC pipes are highly corrosion-resistant, easy to bond, inexpensive, and rigid. However, due to the leaching of PVC monomers and additives, they are only suitable for water supply systems with temperatures not exceeding 45°C. Plastic pipes are used in drainage, wastewater, chemical, heating and cooling fluids, food, ultrapure liquids, slurry, gas, compressed air, and vacuum systems. During the production and processing of PVC pipes, one end needs to be flared to facilitate connection. However, currently, flaring of PVC pipes is generally done using a stamping process. During the stamping and flaring process, PVC pipes are prone to slight movement under impact, affecting the quality of the flaring and reducing the flaring effect. Therefore, an automatic flaring and forming device for PVC pipes is needed. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides an automatic flaring and forming device for PVC pipes. This solves the problem that currently, flaring of PVC pipes is generally carried out using a stamping process, which can easily cause slight movement of the PVC pipe under impact force during the stamping and flaring process, affecting the quality of the flaring process and reducing the flaring effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic flaring and forming device for PVC pipes, comprising a support plate, a fixed seat on the top of the support plate, a fixed block fixedly installed on the top of the fixed seat, a placement tray fixedly installed on the top of the fixed block, a placement groove on the upper surface of the placement tray, a rubber anti-slip pad fixedly installed on the inner wall of the placement tray, support rods fixedly installed on both sides of the top of the support plate, a connecting plate fixedly connected to one end of the support rod, an electric push rod fixedly installed on the surface of the connecting plate, a clamping plate fixedly connected to one end of the electric push rod, a support block fixedly installed on the upper surface of the support plate, an electric hydraulic push rod fixedly installed on one side of the support block, a connecting plate fixedly connected to one end of the electric hydraulic push rod, a flaring insertion rod fixedly installed on one side of the connecting plate, and an auxiliary rod fixedly installed on the surface of the support plate.

[0005] Preferably, the surface of the fixing seat is provided with bolts, and the fixing seat is connected to the support plate by bolts.

[0006] Preferably, the hydraulic push rod is located on the side where the tray is placed.

[0007] Preferably, the clamping plate is semi-circular and is located directly above the tray.

[0008] Preferably, the auxiliary rod is slidably connected to the connecting plate, and there are two auxiliary rods.

[0009] Preferably, a water tank is fixedly installed on the surface of the support block, a water pump is fixedly installed on one side of the water tank, the output end of the water pump is connected to a drain pipe, and a nozzle is fixedly connected to one end of the drain pipe.

[0010] Preferably, the bottom of the support plate is fixedly mounted with a mounting leg, and the surface of the mounting leg is provided with a mounting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] One end of the PVC pipe rests against the placement tray. The electric push rod is activated, causing the semi-circular clamping plate to press down and move. After the clamping plate is pressed down, it can clamp and fix the PVC pipe in the placement tray through the squeezing force, improving the stability of the PVC pipe. The rubber anti-slip pad can enhance the anti-slip effect of the PVC pipe. Since one end of the PVC pipe rests against the placement tray, the force will be blocked when the PVC pipe is subjected to force, so that the PVC pipe will not move slightly during the flaring process, improving the flaring process effect of the PVC pipe and ensuring the quality of the flaring forming process.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides the following technical solution: an automatic flaring and forming device for PVC pipes, including a support plate 1, a fixed seat 2 on the top of the support plate 1, a fixed block 3 fixedly installed on the top of the fixed seat 2, a placement tray 4 fixedly installed on the top of the fixed block 3, a placement groove 5 on the upper surface of the placement tray 4, a rubber anti-slip pad 6 fixedly installed on the inner wall of the placement tray 4, support rods 7 fixedly installed on both sides of the top of the support plate 1, a connecting plate 8 fixedly connected to one end of the support rod 7, an electric push rod 9 fixedly installed on the surface of the connecting plate 8, a clamping plate 10 fixedly connected to one end of the electric push rod 9, a support block 11 fixedly installed on the upper surface of the support plate 1, an electric hydraulic push rod 12 fixedly installed on one side of the support block 11, a connecting plate 13 fixedly connected to one end of the electric hydraulic push rod 12, a flaring insertion rod 14 fixedly installed on one side of the connecting plate 13, and an auxiliary rod 15 fixedly installed on the surface of the support plate 1.

[0021] The PVC pipe requiring flaring is placed into the placement groove 5 on the upper surface of the placement tray 4. The semi-circular placement groove 5 can properly place the round PVC pipe. After placement, one end of the PVC pipe will rest against the placement tray 4, while the other end will protrude from the placement tray 4. The electric push rod 9 is activated, driving the semi-circular clamping plate 10 to press down and move. After pressing down, the clamping plate 10 can clamp and fix the PVC pipe in the placement tray 4 through the squeezing force. At the same time, the rubber anti-slip pad 6 can enhance the anti-slip effect of the PVC pipe. After the electric hydraulic push rod 12 is activated, it can drive the flaring rod 14 to move. After the flaring rod 14 is moved and adjusted, the front end of the flaring rod 14 can move into the fixed PVC pipe. The PVC pipe is continuously moved inside, and the flared rod 14 can flare one end of the PVC pipe through the impact pressure during the movement, thus forming the flared end of the PVC pipe. Since one end of the PVC pipe is pressed against the placement plate 4, the PVC pipe will not move slightly during the flaring process, improving the flaring effect and ensuring the quality of the flaring process. The water pump 17 starts to draw water from the water tank 16, and the drawn water can be discharged into the nozzle 19 through the drain pipe 18. The nozzle 19 sprays water onto the flared rod 14, which can cool the continuously used flared rod 14 and extend its service life. All electrical equipment in this device is powered by an external power source.

[0022] In one aspect of this embodiment, after the electro-hydraulic push rod 12 is started, the electro-hydraulic push rod 12 can drive the connecting plate 13 and the flared insert rod 14 to move, so that the front end of the flared insert rod 14 can move into the fixed PVC pipe and perform flaring processing on one end of the PVC pipe by punching pressure.

[0023] In one aspect of this embodiment, the fixing seat 2 can be removed from the support plate 1 by loosening the bolts on the fixing seat 2, and conversely, the fixing seat 2 can be installed onto the support plate 1 by using bolts.

[0024] In one aspect of this embodiment, after the electro-hydraulic push rod 12 drives the connecting plate 13 to move and adjust, the connecting plate 13 can slide on the surface of the auxiliary rod 15. The auxiliary rod 15 is used to guide the connecting plate 13 and enhance the stability and accuracy of the movement of the connecting plate 13.

[0025] In one aspect of this embodiment, the semi-circular clamping plate 10, after being moved and adjusted, can clamp and fix the PVC pipe placed in the placement tray 4, so that the circular PVC pipe maintains sufficient stability in the placement tray 4 and prevents the PVC pipe from moving slightly during the subsequent stamping and flaring process.

[0026] In one aspect of this embodiment, the mounting leg 20 can be fixed to the ground via the mounting slot, thereby installing and securing the device.

[0027] In one aspect of this embodiment, the water pump 17 is started to draw water from the water tank 16. The drawn water can be discharged into the nozzle 19 through the drain pipe 18. The nozzle 19 sprays water onto the flared plug 14 in use. The sprayed water can cool the flared plug 14 in continuous use and extend its service life.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
