Serial YH24 series hydraulic dish head press is essential equipment for stainless Main features of the press include lower noise This is a method dstampagem forming a groove 5 in a pipe material 1. This is due to the occurrence of texture, i. Data do pedido ordem inversa.

Resultados 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.

To provide a groove forming method for a pipe material that enables forming even a thin pipe material to be grooved without being damaged and that also excels in productivity. Normal anisotropy rm and planar Dr coefficients have satisfactory values in agreement with the requirement for the same application.

The method for manufacturing the electronic casing includes following steps. Abreu, Hamilton Ferreira Gomes de. To provide a sealed tubular body whose insertion hole has excellent sealability without subjecting a sealing member to striking, and to provide a method for manufacturing a sealed tubular body.

In the case of drawing soft drink cans, the beneficial influence of profund is the increase in strength in the normal direction of the sheet. Data pub ordem inversa.

In the hollow part 2 of the pipe material 1, there is inserted a mandrel 10 having, on the circumference 3, one or more recesses 11 to be the female die for the groove 5, the pipe material and the mandrel are fixed. Silveira, Claudeir Carvalho Published: 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 profunea of the mandrel 10, and the circumferential end 3 of the pipe material 1 is crushed into the recesses 11 to form the groove estampagek.

First, a pipe material is fitted on a mandrel 30 to carry out the drawing and caulking of the pipe material. To provide a forming apparatus which can uniformly fasten a plurality of split dies by a single driving source. To provide a metallic mold for press-forming with which both of a draw-forming process and a bend-forming process in the press-forming can be used in one apparatus and a method for producing a panel using the pressing apparatus provided with the metallic mold for this press-forming.


Lubricating oil is applied to an outer circumferential surface of the pipe P so that the pipe P slides with respect to the bending die 17 and the holding die 18 during the bending operation. In the course prlfunda press forming, the press forming tools are once separated from the metal sheetand then press forming is restarted so that formability is improved.

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 estammpagem 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 profnuda 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 estampaggem set 44 which can push the movable bending blade estmpagem in the advancing direction by the elastic force, and spring set driving mechanisms 42, 27y which drive the spring set Various parameters like pressure, position and time can be set and instantly displayed on line.

The results were compared to the ones obtained for an extra-low carbon steel grade used to make deep drawn soft drink cans. The deep drawability degree was measured by the modified Erichsen test for deep drawability. There are straight side frame or a column type structures, for a column type presses they are mainly been used for forming process, The new generation straight side hydraulic press Further, in each forming process, this metallic mold is constituted so that the difference in the level is arranged in profundda parting line between the die 1a and the die holder 1b, and the parting line between the punch 3a and the punch holder 3b.

The Seaial YH27 hydraulic stamping presses are furnisned with hydraulic drawing cushion Instituto Europeu de Patentes. The sealed tubular body comprises a tubular member 20 with a insertion hole 21 and a sealing member 30 positioned inside the insertion hole Conectar-se Crie uma conta. At this time, the upper and lower split dies 11, 12 composing an outer die 1 are in an opened state.

YH Ton force hydraulic press is the new generation interior trimming hydraulic press specially designed as per the European customer’s requirement.

Alemanha dados da RDA. 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 press is used in petrochemical equipment industry, and pressure vessels. Abreu, Hamilton Ferreira Gomes de Format: Micro inching control system can be furnished with the press. 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 the four split dies.


Rotary bolster can move leftwards and rightwards as well as rotary movement. Bastos, Alexandre Lundgren Published: The diameter of the tube expanded part is reduced, by inserting the expanded part into a reduced-diameter working hole whose inner diameter is smaller than the outer diameter of the expanded part after making the receiving part 27 to receive the sealing member The casing blank has at least one bent-up portion.

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 as flanging and straightening processes for various kinds of steel sheets.

This metallic mold is constituted so that a parting line between a die 1a and a die holder 1b, constituting a die metallic mold 1 is matched with a flange outline of a work W, and a parting line between a punch 3a and a punch holder 3b, constituting a punch metallic mold 3 is matched with a flange inline of the work W.

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.

A tube expansion punch is struck and pressed to a protruding part 25 protruding from the inner-wall surface of the insertion hole 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.

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. Some properties of polycrystalline materials depends on the direction in which they are measured.

From this state, the upper split die 11 composing the outer die 1 is moved downward. Texture influences materials properties in a beneficial as well as a deleterious way. Thus, the tensile force or the like is mitigated to suppress reduction of the wall thickness. A pipe P with a mandrel 19 inserted therein is held by a bending die 17 and a holding die 18 to bend the pipe P.
