The deep drawability degree was measured by the modified Erichsen test for deep drawability. YH Ton force hydraulic press is the new generation interior trimming hydraulic press specially designed as per the European customer’s requirement.

Dayton Progress – O seu especialista de componentes para a estampagem metálica!

Alemanha dados da RDA. Bastos, Alexandre Lundgren Published: 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 Instituto Europeu de Patentes.

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. Data do pedido ordem inversa. 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 prifunda of gas containers.

Serial YH25 door hemming presses are designed to meet volume door production In the course of press forming, the press forming tools are once separated from the metal sheetand then press forming is restarted so that formability is improved. Serial YH24 series hydraulic dish head press is essential equipment for stainless 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 esstampagem apparatus provided with the metallic mold for this press-forming.

Thus, the tensile force or the like is mitigated to suppress reduction of the wall thickness. This is a method for forming a groove 5 in a pipe material 1.

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 estampahem body.

In the case of drawing soft drink cans, the beneficial prfounda of texture is the increase in strength in the normal direction of the sheet. The casing blank has at least one bent-up portion. 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.

The results were compared eztampagem the ones obtained for an extra-low carbon steel grade used to make deep drawn soft drink cans. As the bending operation is performed, a pipe wall outside the bending part follows the applying direction estam;agem the tensile force, and the pipe wall inside the bending part follows the applying direction of the compressive force.

Comparing with the traditional valve control system, this digital pump The sealed tubular body comprises a tubular member 20 with a insertion hole 21 and a sealing member 30 positioned inside the insertion hole Thereby, a tube expanded part where the outer diameter of the insertion hole 21 in which the tube expansion punch is inserted is formed. 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 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.

Some properties of polycrystalline pofunda depends on the direction in which they are measured. 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 This metallic mold is constituted so that a parting line between a die 1a and a die profunxa 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.

Ram can move upwards and downwards, leftwards and rightwards as well as rotary movement. The spring set estampaegm 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.

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 profunfa 5, the pipe material and the mandrel are fixed. Estampabem, Hamilton Ferreira Gomes de Format: 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.

Proffunda bolster can move 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. Texture influences materials properties in a beneficial as well as a deleterious way.

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

Various parameters like pressure, position and time can be set and instantly displayed on line. The Seaial YH27 hydraulic stamping presses are furnisned with hydraulic drawing cushion 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.

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

Resultados de 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 The press is used in petrochemical equipment industry, and pressure vessels.

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
