Description

Stamping die for side plate of automobile seat

Technical Field

The utility model relates to a car seat curb plate stamping die belongs to stamping forming technical field.

Background

One first presents the body of a car in front of a car. That is to say the body is the identifying assembly of the car. The body represents the visual characteristic of that type of automobile. The automobile die is a generic term of dies for punching all stampings on an automobile body in a narrow sense. Namely an automobile body stamping die. Such as roof flanging dies, beam stiffener compression dies, and the like. The most important component of the automobile mould is a covering part mould. Such molds are mainly cold stamping dies. The term "automobile mold" in the broad sense is a generic term for molds used to manufacture all parts of automobiles. For example, a press mold, an injection mold, a forging mold, a casting wax mold, a glass mold, and the like.

The press forming is a processing and forming method for obtaining a workpiece (stamping part) with a required shape and size by applying an external force to a plate, a strip, a pipe, a section bar and the like by a press machine and a die to cause plastic deformation or separation. The stamped blanks are mainly hot and cold rolled steel sheets and strips. In the world, 60-70% of steel materials are plates, and most of the plates are punched to form finished products. The body, chassis, oil tank, radiator sheet, boiler steam drum, shell of container, iron core silicon steel sheet of motor and electric appliance are all made by punching. There are also a large number of stamped parts in products such as instruments, household appliances, bicycles, office machines, and household utensils.

Traditional car seat curb plate stamping die can be handled certificate punching press one shot forming through setting up the multislot structure. However, there is a problem in the press forming process:

1. because the corner of mould groove is the right angle, flow resistance is great when the stamping process in panel shaping, easily makes final finished product appear cracked phenomenon, according to the difference of degree of rupture, can divide into the microcosmic and the macroscopical condition of rupture with rupturing. Micro-cracking refers to the creation of cracks in a sheet that are difficult to observe with the naked eye, although the crack depth is shallow, some of the material has failed. Macroscopic cracking refers to the occurrence of macroscopic cracks and fractures in the sheet.

2. Because the total number of the deep-drawing ribs formed between the forming blocks is fixed, and the connection openings of the deep-drawing ribs are not smooth and are relatively stiff, the flow resistance can be increased in the stamping process, and the finished products are easy to break in different degrees.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose provides a car seat curb plate stamping die to the defect that prior art exists.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: a stamping die for a side plate of an automobile seat comprises a die body;

Furthermore, the corners of the first forming block, the second forming block, the third forming block, the fourth forming block, the fifth forming block, the sixth forming block, the seventh forming block, the eighth forming block and the ninth forming block are all set to be smooth circular arcs.

Further, the radius of the arc at the corner of the mold groove is 5mm, and the radii of the arc at the corner of the first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth forming blocks are all 3 mm.

Furthermore, the two side edges and the bottom edge of the second forming block and the fourth forming block are inclined at an angle of 30 degrees, and two lifting rings are fixedly connected to the two sides of the die body.

Furthermore, the third forming block is a rhombus, the angles formed by two adjacent edges of the third forming block are respectively 120 degrees and 60 degrees, and the fourth forming block, the fifth forming block, the sixth forming block, the seventh forming block and the eighth forming block are all irregular forming blocks.

The utility model has the advantages that: when using, the utility model has the advantages of simple whole structure, because the corner in mould groove is glossy convex, under the prerequisite that satisfies part functional requirement, suitably increase mould fillet or reduce the flow resistance that the gradient all can be effectual among the reduction material forming process, thereby less the phenomenon that breaks and appear, the open primary function of deep-drawing muscle switch-on department is that the region that makes easy splitting obtains the material replenishment in adjacent region, in order to improve regional interior the deformation condition that gets, and glossy convex sets up the great reduction the flow resistance of material when replenishing, thereby reduce the probability that breaks and appear. The relation between the stamping forming quality and the lubricant is extremely important, and the sheet material is likely to be pulled apart under poor lubricating conditions or improper selection of the lubricant, so that the quality of the product can be effectively improved by selecting the proper lubricant in the stamping process.
