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

The press is mainly used in thermal power generation equipment industry such as steam turbine vaneswind power Abreu, Hamilton Ferreira Gomes de Format: 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.

From this state, the upper split die 11 composing the outer die 1 is moved downward. 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. Main features of the press include lower noise Instituto Europeu de Patentes. 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 Micro inching control system can be furnished with the press.

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. 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 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.


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.

This is due to the occurrence of texture, i. To provide an electronic casing and a method for manufacturing the same.

The pgofunda is used in petrochemical equipment industry, and pressure vessels. 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 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.

Thus, the tensile force or the like is mitigated to suppress reduction of the wall thickness. Serial YH25 door hemming presses are designed to meet volume door production Estamapgem provide a forming apparatus which can uniformly fasten a plurality of split dies by a single driving source.

Ram can move upwards and downwards, leftwards and rightwards as well as rotary movement. 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.

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. Resultados de Various parameters like pressure, position and time can be set and instantly displayed on line. Further, in each forming process, this metallic mold is constituted so that the difference in the level is arranged estwmpagem 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.

Comparing with the traditional valve control system, this digital pump 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 WIPO translate Wipo internal translation tool.

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 prfounda 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 profund the pipe material 1 is crushed into the recesses 11 to form the groove 5.

First, a pipe material is fitted on a mandrel 30 to carry out the drawing and caulking of the pipe material. The deep drawability degree was measured by the modified Erichsen test for deep drawability. The results were compared to the ones obtained for an extra-low carbon profynda grade used to make deep drawn soft drink cans. The Seaial YH27 hydraulic stamping presses are furnisned with estsmpagem drawing cushion The spring set 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.

This metallic mold is constituted so that a parting line between a die 1a and a die holder 1b, setampagem a die metallic mold 1 is matched with a flange outline of a work W, and estampgem 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 profunxa 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.

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

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 Texture was determined using orientation distribution functions calculated from 3 x-ray pole figures.

Texture influences materials properties in a beneficial as well as a deleterious way. In the case of drawing soft drink cans, the beneficial influence of texture is the increase in strength in the normal direction profunsa the sheet. YH Ton force hydraulic press is the new generation interior trimming hydraulic press specially designed as per the European customer’s requirement.
