Embodiment 1

[0040] This embodiment is a mold for forming a three-way piece on a one-way press, including an upper template 8, a lower template 2, 2 dies 1, 2 horizontal punches 3, a vertical punch 7, and 2 sliders 4 , 2 baffle plates 5, 2 oblique wedges 6 and 2 pads 9.

[0041] The two slide blocks 4 are respectively installed in slide block installation grooves located at both ends of the upper surface of the lower template 2 . The horizontal punch 3 is located between the two slide blocks 4 , and the outer end of the horizontal punch 3 cooperates with the inner surface of the slide block 4 . The two baffles 5 are located on the outer sides of the two sliders 4 respectively, and are embedded in the baffle installation grooves on the upper surface of the lower template 2 . The slopes of the two wedges 6 are respectively placed on the slopes of the two sliders 4, and the dovetail blocks on the side surfaces of each wedge 6 are inserted into the dovetail grooves on the side surface of the ...

Embodiment 2

[0052] This embodiment is a method for forming a three-way piece using the mold for forming a three-way piece on a one-way press described in the first embodiment. In the tee mold used in this embodiment, the slope angles α of the wedge and the slide block are both 45°, and the height of the block is 130 mm.

[0053] The raw material of the tee formed in this embodiment is 7075 aluminum alloy extruded bar, the mold material is AISI-H21 steel, and the formed tee includes branch pipes and main pipes.

Abstract

The invention discloses a device capable of forming a three-way pipe on a one-way pressure machine and a forming method thereof; loading is processed on the one-way pressure machine; an inclined wedge, a cushion block and a sliding block are matched so as to process loading on a plurality of directions; and integrated forming of the three-way piece on the one-way pressure machine is realized. According to the invention, a vertical male mould is connected with an upper template; the upper template is loaded directly; a horizontal male mould is driven through transferring force of the cushion block - the inclined wedge - the sliding block; one-time integrated forming of the three-way piece is realized so as to simply a technological process; when the length of a main branch pipe needs to be regulated or a loading method needs to be exchanged, a cushion block with a different height is substituted separately or a sliding block-inclined wedge with a different inclination is exchanged without taking a whole concave mould or a punch; design flexibility is improved; and working time is shortened. According to the invention, a welding and machining procedure is reduced so as to avoid disadvantages of an etched welding line, a cut flow line and the like; reliability of a component is enhanced; utilization ratio of materials is increased; a demand on loading environment is low; and the device disclosed by the invention is characterized by simple and convenient operation and easy implementation.

Description

technical field [0001] The invention relates to the field of thermal processing, in particular to a device for forming a tee piece on a one-way press and a forming method thereof. technical background [0002] As an important industrial part, the tee is widely used in petrochemical, power industry and other fields. The development of the above fields has put forward higher requirements for the structure and mechanical properties of such parts while the demand for tee parts has become more and more extensive. At present, the processing methods of such parts mainly include casting, welding, bulging and machining. The casting defects of castings are difficult to overcome, and often become a hidden danger of part failure; the wall thickness of tee parts formed by the bulging method is limited and the uniformity is difficult to control; the residual stress at the weld is easy to cause stress corrosion cracking, resulting in pipeline leakage and damage. And the welding parts hav...
