Description
Technical Field
The invention belongs to the field of forging, and particularly relates to an edge cutting and receiving device for a large die forging and a using method of the edge cutting and receiving device.
Background
In the forging production process, due to the fact that the shape of some large die forgings is complex, the size and the weight are large, impact force is large when the die forgings fall to the ground in the trimming process, the forgings are prone to being deformed and local damage of landing points can be caused, meanwhile, due to the fact that the production batch of the large die forgings is small, cost constraint is achieved, correction equipment cannot be arranged, and therefore deformation and damage caused by falling of trimming can bring inconvenience to subsequent processing, and final quality is affected. At present, the problem is generally solved by adopting a method of installing a material receiving bracket or a plurality of ejection oil cylinders on a lower working table of an edge cutting, but the material receiving bracket is easy to break and lose efficacy due to large impact force; and adopt two hydro-cylinder structures, not only need invest in the corresponding hydraulic system of construction, have the hydro-cylinder moreover and ejecting asynchronous, under the effect of big impact force, the condition that the oil leak became invalid appears in the hydro-cylinder atress inequality.

The present invention will be described in detail with reference to the accompanying drawings, and as shown in the drawings, the present invention includes a trimming lower die 1; trimming upper die 2; an upper die holder 3; a first coupling threaded shaft 4; an upper bracket 5; a first nut 6; a transmission link 7; a coupling shaft 8; an oscillating lever 9; a second nut 10; a lower bracket 11; a second coupling threaded shaft 12; a cam 13; a vertical plate 14; a lower blade 15; a lower die holder 16; a third nut 17; a third coupling screw shaft 18.
The trimming upper die 2 is fixed on the upper die holder 3, the upper bracket 5 is fixed on the upper die holder 3, the first connecting threaded shaft 4 is connected with the first nut 6 through a hole at the upper end of the transmission connecting rod 7 and a hole of the upper bracket 5, the vertical plate 14 is fixed on the lower die holder 16, and the trimming lower die is arranged between the vertical plates 14; the 4 cams 13 are fixed at four corners of the lower supporting plate 15 (i.e., two sides of the front end and the rear end of the supporting plate 15), and the lower supporting plate 15 is placed between the two vertical plates 14; the lower support 11 is fixed on the lower die base 16, the connecting shaft 8 penetrates through a hole at the lower end of the transmission connecting rod 7 and a hole at one end of the oscillating rod 9, the third connecting threaded shaft 18 penetrates through a hole in the middle of the oscillating rod and a hole of the lower support 11 to be connected with a third nut 17, the upper support 5, the transmission connecting rod 7, the oscillating rod 9 and the lower support 11 form a connecting rod mechanism, the second connecting threaded shaft 12 penetrates through a hole at the other end of the oscillating rod 9 and a cam groove of the cam 13 to be connected with the second nut 10, and the oscillating rod 9 and the cam 13 form a cam mechanism.
The distance between the two first coupling threaded shafts 4 is smaller than the distance between the two coupling shafts 8.
The use principle of the invention is as follows:
when the device works, the trimming press slide block drives the upper die holder 3, the trimming upper die 2 and the upper support 5 to move downwards, the upper support 5 drives the transmission connecting rod 7 to rotate anticlockwise (fig. 3, 4 and 6) through the first connecting threaded shaft 4, and the movement of the transmission connecting rod 7 is transmitted to the oscillating rod 9 through the connecting shaft 8, so that the oscillating rod 9 rotates clockwise around the third connecting shaft 18;
the clockwise rotation of the swing rod 9 is transmitted to the cam 13 through the second connecting threaded shaft 12 and drives the lower supporting plate 15 to move upwards, the second connecting threaded shaft 12 slides in the cam groove, and when the second connecting threaded shaft 12 is in the rising stage of the cam groove, the cam and the lower supporting plate are in a vertical rising state; in order to prevent the lower supporting plate from interfering with the lower bottom surface of the trimming lower die and prevent the forged piece after trimming from colliding with the lower supporting plate which is rising when falling, when the cam and the lower supporting plate rise to a certain height, a certain distance is reserved between the lower supporting plate 15 and the lower bottom surface of the trimming lower die 1, so that the track of the second coupling threaded shaft 12 moves relative to the cam in the stopping stage of the cam groove, the height of the lower supporting plate is at a certain height position and does not move upwards, and the cam groove comprises an arc-shaped section 1302 and a straight section 1301; the arc-shaped section is a concentric arc type with the third connecting threaded shaft 18 as a circle center, so that when the second connecting threaded shaft 12 slides in the arc-shaped section 1302 of the cam groove, the lower supporting plate 15 can be ensured to be at a certain height position and not move up and down;
