Description

Technical Field

[0001] The utility model relates to the technical field of forming devices, in particular to a pipe fitting extrusion forming device. Background Technique

[0002] A pipe fitting extrusion forming device is an industrial equipment for manufacturing metal pipe fittings. It manufactures pipe fittings by extrusion forming, applying an external force on the material surface to cause plastic deformation of the material, thereby manufacturing products with specific shapes and sizes.

[0003] Common forming devices generally place the material of the pipe fitting into the lower die, and install a mandrel in the inner cavity of the lower die to maintain the internal cavity of the pipe fitting and prevent the material from collapsing or deforming during extrusion. The upper die is driven by a hydraulic telescopic rod to move downward to extrude the lower die, thereby manufacturing the pipe fitting.

[0004] However, when extruding the pipe fitting, since the pipe core needs to be installed in the die, after the pipe fitting is manufactured, the pipe fitting will be blocked by the mandrel and cannot be directly taken out of the die. The lower die needs to be disassembled to take out the formed pipe fitting, and the disassembly of the lower die takes time for manufacturing the pipe fitting, resulting in a more cumbersome manufacturing process for the pipe fitting. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a pipe fitting extrusion forming device to solve the problems mentioned in the above background technique that the lower die needs to be disassembled to take out the formed pipe fitting, and the disassembly of the lower die takes time for manufacturing the pipe fitting, resulting in a more cumbersome manufacturing process for the pipe fitting.

[0006] To achieve the above object, the utility model provides the following technical solution: A pipe fitting extrusion forming device, comprising:

[0007] A base, on the rear part of the upper surface of which an installation frame is installed;

[0008] A hydraulic telescopic rod, arranged on the upper surface of the installation frame. The bottom end of the hydraulic telescopic rod penetrates through the upper surface of the installation frame and is installed with an upper die, and a first shaping plate is uniformly arranged at the bottom of the upper die;

[0009] A lower die, arranged on the rear part of the upper surface of the base. Shaping grooves are uniformly opened on the upper surface of the lower die, second shaping plates are installed in the inner cavities of the shaping grooves, and insertion ports are uniformly opened on the front surface of the lower die;

[0010] A driving machine, arranged on the right side of the upper surface of the base. A lead screw is coaxially installed on the rotor of the driving machine. A driving block is screwed on the surface of the lead screw. An installation plate is installed on the upper surface of the driving block. Mandrels are uniformly installed on the back surface of the installation plate. The mandrels penetrate through the insertion ports and are inserted into the inner cavities of the shaping grooves.

[0011] Preferably, sliders are installed on both sides of the bottom of the mounting plate, and chutes are opened on both sides of the upper surface of the base. The sliders are embedded in the inner cavity of the chutes, and the sliders and the chutes enable the mounting plate to move linearly.

[0012] Preferably, first sealing grooves are evenly opened on the front surface of the lower mold, and a first sealing ring is installed at the front part of the mandrel. The first sealing grooves are inserted into the inner cavity of the first sealing ring, and the part where the insertion port contacts the mandrel can be sealed.

[0013] Preferably, a receiving port is opened on the rear inner wall of the shaping groove, and a receiving rod is installed at the rear end of the mandrel. The receiving rod is inserted into the receiving port, and the mandrel can be supported.

[0014] Preferably, a second sealing groove is opened on the rear inner wall of the shaping groove, and a second sealing ring is installed at the rear end of the mandrel. The second sealing ring is inserted into the second sealing groove, and the gap between the receiving rod and the receiving port can be sealed.

[0015] Preferably, sealing plates are installed at the corresponding positions of the bottom of the upper mold and the first shaping plate. The first shaping plates are all installed at the bottom of the sealing plates. When the sealing plates move downward, the upper opening of the shaping groove can be sealed.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] In this pipe fitting extrusion forming device, the added hydraulic telescopic rod can drive the upper mold to move downward, thereby driving the first shaping plate to move downward. Cooperating with the second shaping plate, the material in the lower mold can be extruded. After the pipe fitting is manufactured, starting the driving machine can drive the lead screw to rotate, thereby driving the driving block to move, and further driving the mounting plate to move, and the mandrel can be withdrawn from the shaping groove, so as not to obstruct the formed pipe fitting, making it possible to take out the pipe fitting without disassembling the lower mold, reducing the steps of taking out the pipe fitting, and enabling the pipe fitting to be quickly taken out from the lower mold.
