Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of forging shaping mould of special-shaped structural member, belong to forging shaping technical field. BACKGROUND

[0002] Certain stainless steel special-shaped structural member, such as Figure 2 As shown, the whole wall thickness is 2 millimeters, transverse length 320mm, width 50mm, longitudinal length 220mm, width 38mm, different curved surface is presented in multidimensional space, and after casting forming or machine adding shaping, its distortion and warping deformation are serious, need to use external force to knock wing position when assembling, then fixed by screw, make it hard assembly in place. CONTENT OF UTILITY MODEL

[0003] The utility model provides a kind of forging shaping mould of special-shaped structural member.

[0004] The utility model aims to realize by the following technical scheme:

[0005] The utility model discloses a kind of forging shaping mould of special-shaped structural member, including upper die, lower die, the inner shape surface of the upper die is matched with the outer shape surface of part, single side clearance 0.1mm, profile extension 2mm above excess, simultaneously be connected with the workbench on forging equipment;The inner shape of the lower die is matched with the outer shape part, single side clearance 0.1mm, profile extension 2mm above excess, height direction increases 1mm excess, bottom is increased 8×1 ring groove again, increase to avoid space, prevent die knock, simultaneously be connected with the workbench under forging equipment.

[0006] The upper die and the guide position of the lower die adopt the guide form of square groove and square column, and the square clearance is 0.1mm, which better ensures the position accuracy.

[0007] The upper die and the lower die are processed from H13 die steel material. The die has sufficient strength and toughness, and can withstand large impact load, thereby prolonging the service life of the forging die.

[0008] Beneficial effects:

[0009] The forging shaping mould is simple to operate, safe and reliable, and is suitable for shaping of twisted and warped parts. The forging shaping mould realizes forging shaping of special-shaped structural cable cover products, and the products have stable quality and good consistency, meeting the requirements of product size and assembly.

[0013] The content of the utility model is further described below in combination with the drawings and examples.

[0014] Embodiment

[0015] As Figure 1 shown, the utility model relates to a forging and shaping die of special-shaped structural member, including upper die 1, lower die 2, the inner profile surface of upper die 1 is matched with the outer profile surface of part, one side gap is 0.1mm, profile face is prolonged by 2mm or more excess, simultaneously being connected with the upper workbench of forging equipment;The inner profile of lower die 2 is matched with the outer profile of part, one side gap is 0.1mm, profile face is prolonged by 2mm or more excess, the height direction increases 1mm excess, the bottom is additionally increased 8x1 ring groove, increases the clearance space, prevents the die from bumping, simultaneously being connected with the lower workbench of forging equipment.

[0016] The guide position of the upper die and the lower die adopts the guide form of square groove and square column, and the square clearance is 0.1mm, so that the position accuracy is better guaranteed.

[0017] The upper die and the lower die are processed using H13 die steel material, so that the die has sufficient strength and toughness, and the service life of the forging die is resistant to large impact load.

[0018] The specific forging and shaping process is as follows:

[0019] First step: the T slot of the die is matched with the T slot of the equipment, and the die is fastened and installed using screws;

[0020] Second step: the forming surface of upper die 1 and lower die 2 is smeared with machine oil for lubrication;

[0021] Third step: the part is preassembled on the forming surface of lower die 1, and the gap is uniform.

[0022] Fourth step: forging: the die is closed using (520-550)T pressure, and forging is carried out.

[0023] Fifth step: part taking and self-inspection: the product is placed on a flat plate to check the degree of distortion and warping deformation.

[0024] Sixth step: polishing the surface of the part and the flash.
