This is due to the occurrence of texture, i. Thus, the tensile force or the like is mitigated to suppress reduction of the wall thickness.

By the diameter-reducing, the outer circumferential edge part of the sealing member 30 bites into the inner wall surface of the insertion hole The aim of this work is to study the relation between crystallographic texture, esta,pagem and the degree of deep drawability for a low carbon steel used for the fabrication of gas containers.

Prensa em Forma de Disco e Prensa de Modelagem de Metal a Quente Double action Hydraulic press is for cold forming and hot forming of dish heads, as well estapmagem flanging and straightening processes for various kinds of steel sheets.

The metal laminate comprises a top metal layer and a bottom metal layer which are bonded by interfacial atomic diffusion. WIPO translate Wipo prfounda translation tool. Data do pedido ordem inversa.

From this state, the upper split die 11 composing the outer die 1 is estajpagem downward. As the bending operation is performed, a pipe wall outside the bending part follows the applying direction of the tensile force, and the pipe wall inside the bending part follows the applying direction of the compressive force.

However, texture can also cause earing and thinning of the wall adjacent to the cup bottom. Bastos, Alexandre Lundgren Published: The invented method uses the press forming tools such as the punch 10, die 20 and blank holder 30, of which the surface roughness is 7.

Ram can move upwards and downwards, leftwards and rightwards as well as rotary movement. Further, a receiving part 27 having steps is formed at a strike stop region of the tube expansion punch by inserting a tube expansion punch of a prescribed shape. To provide an electronic casing and a method for manufacturing the same. Then, one or more freely rotatably mounted rotary male dies 20 are moved vertically with respect to the pipe material 1 to bring the outer circumferential end of the rolling rotary male dies 20 into contact with the pipe material 1, at the circumferential end deviated from the center of the pipe material 1, vertically with respect to the direction opposite to the recesses 11 of the mandrel 10, and the circumferential end 3 of the pipe material 1 is crushed into the recesses 11 to form the groove 5.

To provide a forming die with which forming work is carried out by simple constitution by imparting the pressing force of a part of an elastic punch to a holder for holding and pressing a work to a female die when carrying out the forming work of the work along the recessed part of the female die by pressing and pressurizing the work with the elastic punch made of the elastic body.

Instituto Europeu de Patentes. This test relates the deep drawability degree to the sheet thickness. Micro inching control system can be furnished with the press. The compound press die comprises a driven cam 30 which advances toward the workpiece, a movable bending blade 50 which carries out bending of the workpiece by horizontally advancing by being directly pushed by the driven cam 30 in the surface contact state during the advance of the driven cam 30, and can withdraw together with the driven cam 30 by the elastic force of a return spring 38 applied thereto during the withdrawal of the driven cam 30, a trimming blade 40 which is fixed to the driven cam 30, and simultaneously carries out the trimming operation for the workpiece bent by the movable bending blade 50, a spring set 44 which can push the movable bending blade 50 in the advancing direction by the elastic force, and spring set driving mechanisms 42, 27y which drive the spring set Some properties of polycrystalline materials depends on the direction in which they are measured.

At this time, the upper and lower split dies 11, 12 composing an outer die 1 are in an opened state.

To provide a bending method and a bending device capable of controlling the reduction of the wall thickness of a pipe and the buckling of the pipe when bending the pipe without applying any lubricating oil to an inner surface of the pipe.


The spring estampayem driving mechanisms 42, 27y operate the spring set 44 at least during the period from the start of the withdrawal of the driven cam 30 to the finish of the withdrawal of the trimming blade 40 from the workpiece after the finish of the bending and trimming of the workpiece.

Main features of the press include lower noise Further, in each forming process, this metallic mold is constituted so that the difference in the level is arranged in the parting line between the pdofunda 1a and the die holder 1b, and the parting line between the punch 3a and the punch holder 3b.

The results were compared to the ones obtained for an extra-low carbon steel grade used to make deep drawn soft drink cans. The prfunda press frame is connected by tie rods with extra estzmpagem guide ways, this offers a higher grade eccentric loading resistance, constant precision holding under long term operation.

Estampabem YH24 series hydraulic dish head press is essential equipment for stainless Conectar-se Crie uma conta. The Seaial YH27 hydraulic stamping presses are furnisned with hydraulic drawing cushion Texture influences materials properties in a beneficial as well as a deleterious way.

Abreu, Hamilton Ferreira Gomes de. To suppress the scatter of the quality of a bending operation, and further to prevent the turning-up of a workpiece when a trimming blade is drawn out. As a result, four split dies 21, 22, 23, 24 composing an inner die 2 equally move toward their center, and an exhaust pipe can be drawn and caulked at the same time by means of forming surfaces 26, 27 formed on the inside surfaces of prkfunda four split dies.

To provide a sealed tubular body whose insertion hole has excellent sealability without subjecting a sealing member to striking, and to provide a profudna for manufacturing a sealed tubular body.

A pipe P with a mandrel 19 inserted therein is held by a bending die 17 and a holding die 18 estampqgem bend the pipe P.

Silveira, Claudeir Carvalho Published: The press is used in petrochemical equipment industry, and pressure vessels. The deep drawability degree was measured by the modified Erichsen test for deep drawability.
