Detailed Description
The present invention will be further described with reference to the drawings and examples, in which the brake pad 6 is used as a product, and the structure of the brake pad is shown in fig. 1 and 2.
As shown in fig. 5 and 6, the universal beveling die of the invention comprises an upper die, a die holder 1, a nitrogen spring 2 arranged in the die holder 1, a female die 3 connected with the upper end of the die holder 1 and an insert 4 connected in the female die 3 in a penetrating way; the insert 4 is provided with a recess for placing the product; the female die 3 is provided with a concave part 31 for accommodating the upward and downward directional sliding of the insert 4; the piston rod of the nitrogen spring 2 is connected in the female die 3 in a penetrating way and pushes the insert 4 upwards, and the piston rod of the nitrogen spring 2 drives a product to protrude out of the upper end of the female die 3 against the upper push of the insert 4; the side wall of the recess 31 is provided with a molding structure 31a for controlling the molding of the product; the upper die presses the insert 4 and the press-controlled product of the product into the molding structure 31 a.
In the hypotenuse stamping of the brake pad 6, the brake pad 6 is placed in the groove; the upper die is punched downwards, the upper die is in contact with a product and/or the insert 4, the insert 4 drives the brake pad 6 to move downwards along the concave part 31 in a guiding way, meanwhile, a piston rod of the nitrogen spring 2 is compressed and contracted, the upper die is used for uniformly punching the brake pad 6, the brake pad 6 is gradually compressed and molded on the molding structure 31a, and the inclined edge on the brake pad 6 is extruded and molded.
The structures of the insert 4 and the die 3 are shown in fig. 3 and 4, the die 3 and the insert 4 are arranged, the insert 4 drives a product to guide and slide, the brake pad 6 is in directional abutting connection with the forming structure 31a, forming errors of the oblique side of the brake pad 6 are effectively eliminated, and the oblique side has higher smoothness and roughness.
The nitrogen spring 2 can control the insert 4 to extend out of the female die 3 to the upper top of the insert 4. When the upper die is contracted, the insert 4 drives the brake pad 6 to extend out of the female die 3, so that the brake pad 6 can be conveniently fed and discharged. The stamping force borne by the brake pad 6 is increased on the upper top of the nitrogen spring 2, and the brake pad 6 is better in molding and small in shape and position deviation due to the larger stamping force and the relatively uniform stamping.
As shown in fig. 5 and 6, two nitrogen springs 2 are provided, the top force borne by the insert 4 is balanced, and the guiding of the insert 4 during sliding is effectively ensured.
As shown in fig. 5 and 6, the upper end surface of the female die 3 is provided with a buffer member 5, and the upper end surface of the buffer member 5 is higher than the upper end surface of the product. In the undershoot of the upper die, the upper die is firstly abutted against the buffer piece 5; then the upper die is abutted against the product and/or the insert 4 at a constant speed, so that the brake pad 6 is effectively prevented from being suddenly stamped by the upper die, and the upper end of the brake pad 6 is prevented from being deformed.
As shown in fig. 5 and 6, the side wall of the recess 31 is provided with a plurality of spherical bodies for abutting against the outer wall of the insert 4, and the abutment of the plurality of spherical bodies against the outer wall of the insert 4 is used for controlling the insert 4 to slide in an oriented manner. The guiding force for sliding the insert 4 is given by several spherical surfaces. Compared with wall surface type guiding, the guiding of a plurality of spherical bodies is more accurate, and sliding friction of the insert 4 is effectively reduced.
As shown in fig. 5 and 6, the piston rod of the nitrogen spring 2 is pushed against the insert 4 by the rod piece 6, and the end part of the rod piece 6 connected with the piston rod is provided with a concave spherical surface; the end part of the rod piece 6 connected with the piston rod is provided with a convex spherical surface. The nitrogen spring 2 pushes up the mold insert 4 through the universal structure, so that the guiding precision of the mold insert 4 is effectively ensured, and the mold insert 4 is prevented from being twisted relative to the female die 3 due to the pushing force when the nitrogen spring 2 directly pushes up the mold insert 4.
As shown in fig. 5 and 6, the die holder 1 is provided with a clamping groove for mounting the die 3 in alignment. The female die 3 is assembled on the die holder 1 in an aligned mode, and the piston rod of the nitrogen spring 2 is prevented from being clamped with the female die 3.
As shown in fig. 5 to 9, the die holder 1 includes a first lower pad 11, a second lower pad 12 and a base plate 13 which are layered from top to bottom; the housing of the nitrogen spring 2 is simultaneously connected with the seat plate 13 and the second lower base plate 12 in a penetrating way, and the piston rod of the nitrogen spring 2 is connected with the first lower base plate 11 in a penetrating way. The seat plate 13 and the second lower pad 12 are used for mounting the nitrogen spring 2.
