Description
Technical field
The invention belongs to petrochemical equipment and make the field, relate generally to a kind of manufacture method of special-shaped clamping fixture.
Background technology
In the petrochemical industry equipment was made, we often ran into some special-shaped joints, as flange conical head, hemispherical dome, special-shaped beveled cone etc.General thickness is greater than the special-shaped beveled cone manufacturing of 20mm, and domestic present manufacturing technology mainly adopts the manufacturing of drop stamping technology, but the general employing casting and the rivet welding spare of stamping parts punching press mold; The mold cost of casting is higher, long in time limit, is applicable to big in batches workpiece; Rivet welding spare mold cost is low, the duration short, is applicable to little in batches workpiece.
The mold design must have systematic point of view with manufacturing, must consider enterprise practical situation and production in batches, is guaranteeing to seek the Technological Economy of the best under the product quality premise.
Mainly analyze the features of shape of this part during internal model making, size, whether factors such as required precision and material property meet the requirement of Sheet Metal Forming Technology.In addition, analyze part drawing and also want the difficult point place of clear and definite this part of punching press, for the dimension limit on the part drawing, design basis and attenuation amount, warpage, the influence of factors such as resilience will be considered when making, determine the version of mould and the intensity of mould according to the size of forcing press, rigidity, and mold Center of Pressure.
At high-strength steel material convergent beveled cone, be abnormity component, complex structure.It generally is characterized as: upper and lower port is not parallel, and two interior cross sections of port are for just round about only having, and all the other cross sections are irregular ellipse; The osculum internal diameter is below 300mm, and big mouthful internal diameter is more than 1000mm, and vary in diameter is too big; Large end face is bigger with the angle of inclination of main body axis, and member thickness is more than 20mm; The high-strength steel material has API-5LG.X65, API-5LG.X70 API-5LG.X80 etc.; High-strength steel material yield strength is big, and special-shaped beveled cone osculum diameter is little, can't utilize the rolling method to be shaped, the section configuration complexity, and difficulty is determined in punching press internal model making, mold Center of Pressure.
The internal model making of general rivet welding spare is to utilize the view principle mold cross dimensions of drawing, when internal model making, need consider factors such as periderm thickness, stamping parts thickness, punching press rebound amount, cause size, the shape of each section upper and lower port when making mold to change, and changing does not have rule, is the irregular ellipse of a gradual change.Utilize traditional setting out method to need artificial treatment figure and lot of data information, not only to repeatedly change the perspective plane, and mapping process complexity, boost line are various, workload is big, efficient is low, make mistakes easily, therefore utilize traditional three-view diagram setting out method to be difficult to accurately obtain the size and dimension of making the required section of mold.The mold Center of Pressure should be consistent with the press ram center, if inconsistent, can produce unbalance loading during punching press, causes the rapid wearing and tearing of mold and press ram and guide rail, reduces the service life of mould and forcing press.The complex-shaped definite mold of abnormity beveled cone Center of Pressure difficulty.
Summary of the invention
The present invention overcomes the defective that adopts traditional view setting out method to be difficult to accurately obtain size, shape and the mold center of gravity of making the required section of mold.A kind of manufacture method of special-shaped clamping fixture is provided, and is to utilize the 3 d part design software, designs the model of mold and the assembly relation of member; Demonstrate the threedimensional model of obform body, directly intercept the true form and the size of making the mold model again.Special-shaped clamping fixture is divided into 1/2 punching press, makes two cover punching press molds, determine the mold center of gravity.The version of mold adopts punch-die seben form.The present invention is by 1, goes up the tire base plate, and 2, go up the tire web, 3, the top periderm, 4, the bottom periderm, 5, tire web down, 6, seben, 7, tire base plate down, 8, strengthen gusset, be welded to each other and form; The present invention is divided into 1/2 punching press, makes upper and lower two cover punching press molds, determines the mold center of gravity, and the version of mold adopts punch-die seben form.Its concrete scheme is as follows: at first, on following tire base plate, vertical welding connects at least one tire web down, and the spacing between the following tire web equates that the common concave surface that forms of each time tire web is tapered; Between each time tire web, all be welded with seben, to fill up down the Ullage between the tire web; In the following side of tire web, be and laterally be welded with the reinforcement gusset, play reinforcement effect; On the common taper concave surface that forms of each time tire web, the bottom periderm is installed, this bottom periderm is big or small corresponding with the taper concave surface; Form the bottom mold.Secondly, vertical welding connects tire web at least one on last tire base plate, and the spacing between the last tire web equates that the common convex surface that forms of tire web is tapered on each, and is corresponding with the taper concave surface that following tire web forms; On the common taper convex surface that forms of tire web, the top periderm is installed on each, this top periderm is big or small corresponding with the taper convex surface, forms the top mold.At last, the top mold is installed in the mold of bottom, promptly constitutes the described special-shaped clamping fixture of invention.
Beneficial effect: adopt the manufacture method of special-shaped clamping fixture provided by the present invention, the speed of making mold is fast, has reduced the mold production cost, the mold of producing is the precision height not only, Functionality, quality and appealing design, and save human and material resources, financial resources, can create bigger economic results in society.
