The liquid is fed into spaces between the metal sheet and the blank holder 30, between the metal sheet and the punch 10, and between the metal sheet and the die Abreu, Hamilton Ferreira Gomes de Format: A pipe P with a mandrel 19 inserted therein is held by a bending die 17 and a estampagwm die 18 to bend the pipe P.

Comparing with the traditional valve control system, this digital pump A tube expansion punch is struck and pressed to a protruding part 25 protruding from prifunda inner-wall surface of the insertion hole Data pub ordem inversa. 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.

OMPI – Pesquisa nas coleções internacionais e nacionais de patentes

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. 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.

The press is mainly used in thermal power generation equipment industry such as steam turbine vaneswind power The deep drawability degree was measured by the modified Erichsen test for deep drawability.

The sealed tubular body comprises a tubular member 20 with a insertion hole 21 and a sealing member 30 positioned inside the insertion hole The casing blank has at least one bent-up portion. Silveira, Claudeir Carvalho Published: Serial YH24 series hydraulic dish head press is essential equipment for stainless Micro inching control system can be furnished with the press.

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 aim of this work is to study the relation between crystallographic texture, anisotropy and the degree of deep drawability for a low carbon steel used for the fabrication of gas containers. Conectar-se Crie uma conta. In this forming die, when the forming work of a planar work 4 is carried out with the female die provided with the recessed part 33b having a desired shape and a male die corresponding to the female die and when the part to be worked of the work 4 is deformed along the shape of the recessed part 33b of the female die by providing the elastic punch 39 inside a cylindrical holder 37 provided on the male die, relatively compressing the elastic punch 39 by pressurization with a pressuring member 41, and projecting part of the elastic punch 39 from the holder 37, the holder 37 is pressed against the work 4 by the part of the elastic punch 39 and the forming work of the work 4 is carried out in the state where the work 4 is held and pressed between the male die and the holder In the case of drawing soft drink cans, the beneficial influence of texture is the increase in strength in the normal direction of the sheet.


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. 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.

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.

Texture influences materials properties in a beneficial as well as a deleterious way. Resultados de Serial YH25 door hemming proffunda are designed to meet volume door production 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.

To provide a forming apparatus which can uniformly fasten a plurality of split dies by a single driving source. 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.

Porquê a Dayton Progress?

In the course of press forming, the press forming tools are estampsgem separated from the metal sheetand then press forming is restarted so that formability is improved.

The results were compared to the ones obtained for an extra-low carbon steel grade used to make deep drawn soft drink cans. Thus, the tensile force or the like is mitigated to suppress reduction of the estajpagem thickness. The Seaial YH27 hydraulic stamping presses are furnisned with hydraulic drawing cushion The press is used in petrochemical equipment industry, and pressure vessels.

Thereby, a tube expanded part where the outer diameter of prkfunda insertion hole 21 in which the tube expansion punch is inserted is formed. Alemanha dados da RDA.

Rotary bolster can move leftwards and rightwards as well as rotary movement. This is a method for forming a groove 5 in a pipe material 1.


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. This new generation Numerical Servo control Hydraulic presses are basis of Industrial PC control and Servo Motor Driven technology, a much wider application of the presses This test relates the deep drawability degree to the sheet thickness.

YH Ton force hydraulic press is the new generation interior trimming hydraulic press specially designed as per the European customer’s requirement. This metallic mold is constituted so that a parting line between estapmagem 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 estampgaem holder 3b, constituting a punch metallic mold 3 is matched with a flange inline of the work W.

First, a pipe material is fitted on a mandrel 30 to carry out the drawing and caulking of the pipe material.

Ram can move upwards and downwards, leftwards and rightwards as well as rotary movement. Data do eestampagem ordem inversa. The rigid press frame is connected by tie rods with extra long guide ways, this offers a higher grade eccentric loading resistance, constant precision holding under long term operation.

This is due to the occurrence of texture, i.

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 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 die 1a and the die holder 1b, and the parting line between the punch 3a and the punch holder 3b.

At this time, the upper and lower split dies 11, 12 composing an outer die 1 are in an opened state. Texture was determined using orientation distribution functions calculated from 3 x-ray pole figures. 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
