Technical Field

[0001] The invention relates to the technical field of pipe processing equipment, in particular to full-automatic PVC pipe bending and expanding equipment. Background Art

[0002] PVC elbow is a bent pipe made of polyvinyl chloride material, and the expansion equipment is a kind of equipment used to process and produce PVC pipes. The expansion equipment is mainly used to expand the pipes. Through different molds and process settings, the expansion of pipes of different diameters and shapes can be achieved. The expansion equipment usually adopts hydraulic or mechanical transmission mode, with precise processing capabilities and high production efficiency.

[0007] Preferably, the front crossbeam and the front side of the right front end supporting leg are both fixedly connected with fixing frames, and a discharge plate is fixedly connected between the tops of the two fixing frames.

[0008] Preferably, a centering receiver is fixedly connected at the center position of the bottom rear side of the sliding seat, and a centering sensor is fixedly connected at the center position of the front side of the second placement rack.

[0009] Preferably, two second sliding columns are fixedly connected to the top of the moving bar, and the second sliding columns penetrate and extend to the top of the support beam. A second limiting ring is fixedly connected to the top of the support beam surface.

[0010] Preferably, a driving motor is fixedly connected to the left side of the top of the top plate, a threaded rod is fixedly connected to the output end of the driving motor, the threaded rod is threadedly connected to the sliding seat, and the threaded rod passes through the left side plate and extends to the left side of the right side plate.

[0011] Preferably, a first placement rack is arranged between the two side panels, a transition plate is fixedly connected to the top of the first placement rack, the first placement rack is fixedly connected to the top plate, the left and right sides of the top of the second placement rack are fixedly connected to discharge plates, the opposite sides of the two discharge plates are fixedly connected to limit strips, and a rear plate is fixedly connected between the rear sides of the two side panels.

[0012] Preferably, a connecting column is fixedly connected to the rear side of the supporting leg on the rear right side, and a control box is fixedly connected to the top of the connecting column.

[0013] Preferably, the left side panel is fixedly connected to a first cylinder, and first sliding columns are provided on both the left and right sides and the front and rear sides of the first cylinder. A first limiting ring is fixedly connected to the left side of the surface of the first sliding column, and the first sliding columns penetrate and extend to the right side of the left side panel, and the first sliding columns are slidably connected to the side panel.

[0015] Working principle: First, place one end of the PVC elbow between the two discharge plates, and the other end of the PVC elbow is located on the top surface of the left discharge plate. Because the second placement rack is tilted, the discharge plate is also tilted. Due to its own weight and the extrusion of the PVC elbow behind it, the PVC elbow slides forward along the inclined surface of the discharge plate to the bottom of the discharge plate. The second cylinder further contracts, and the output end of the second cylinder drives the connecting frame to move downward, and the connecting frame drives the lifting plate to descend together, so that the lifting plate shrinks in the sliding seat, and the PVC elbow loses the restriction of the limit plate and falls to the top of the holder along the extension piece. The third cylinder extends, driving the moving bar and the extrusion piece at the bottom of the moving bar to move downward together, and the extrusion piece and the holder clamp the PVC elbow The heating wire in the extrusion piece heats and softens the PVC elbow, and then the first cylinder works. The output end of the first cylinder with the expansion head is inserted into the PVC elbow port to expand the PVC elbow. After further expansion, the third cylinder contracts the extrusion piece to rise. After the PVC elbow loses the restriction of the extrusion piece, the second cylinder extends out of the connecting frame and rises, driving the lifting plate to rise. The two lifting plates extend from the base to lift the PVC elbow upward. Due to the structural setting of the lifting plate, the PVC elbow is pushed forward and falls on the surface of the transition plate. After that, the PVC elbow continues to slide forward along the inclined surface of the transition plate until the PVC elbow falls on the discharge plate. The PVC elbow continues to slide along the discharge plate, and finally the collection box is placed at the bottom on the right side of the discharge plate to collect the PVC elbow.

[0016] The present invention provides a fully automatic PVC pipe bending and expanding device, which has the following beneficial effects:

[0017] 1. The present invention places the PVC elbow between two feeding plates, contracts the second cylinder to make the PVC elbow fall into the slot on the holder, then the third cylinder squeezes the extrusion piece downward, and the heating wire in the extrusion piece heats the PVC elbow, and finally the first cylinder extends to insert the expansion head at the output end into the PVC elbow port. No manual operation is required, and the PVC elbow only needs to be placed between the two feeding plates, thereby improving the processing efficiency of the PVC elbow, reducing the labor cost, and stabilizing the processing quality of the PVC elbow.

[0018] 2. The present invention uses screws to fix various structures together, and then the corresponding module structure can be replaced as needed to be suitable for bending pipes of different materials and models. The entire equipment is compact and integrated to reduce the footprint. At the same time, it can be disassembled and installed at the discharge of the pipe bending machine as needed. It can be suitable for the expansion processing of plastic bent pipes of different sizes and models, and has high production efficiency and is convenient for mass production.
