Problems solved by technology

[0003] The traditional bonnet outer panel process arrangement is: OP10 drawing, OP20 trimming, OP30 side flanging, OP40 flanging, side flanging. Due to the shape of the engine cover outer panel parts, peripheral flanging is required, and three Side flanging, the mold adopts the traditional push-pull wedge and cannot be arranged in one process, so it needs to be split into two processes

Embodiment Construction

[0019] Below the present invention is further described:

[0020] see Figure 1-5 ,

[0021] The invention discloses a novel linkage rotating wedge, which comprises a wedge base 1, a punch 2 with an engine cover outer plate on the upper surface of the wedge base 1, and two rollovers on both sides of the punch 2 A side mechanism 3, the front end of the punch 2 is provided with a middle screen side flanging mechanism 4, and two lamp mouth corner flanging mechanisms 5 are arranged between the side flanging mechanism 3 and the middle mesh side flanging mechanism 4 ; During work, after the center grid side flanging mechanism 4 and the two lamp opening angle flanging mechanisms 5 rotate clockwise for 25° at the same time, the two side flanging mechanisms 3 rotate clockwise for 15°, and the above actions pass The air source switch controls the cylinder. Through the above actions, the problem of picking up parts after negative angle flanging of the circle is solved. At the same time...

Abstract

The present invention relates to the technical field of flanging of the engine cover outer plate, in particular to a novel linkage rotating wedge, comprising a wedge base, a punch provided with an engine cover outer plate on the upper surface of the wedge base, and a punch of the punch There are two side flanging mechanisms on both sides, the front end of the punch is provided with a middle mesh side flanging mechanism, and there are two lamp mouth corner turning mechanisms between the side flanging mechanism and the middle mesh side flanging mechanism. Edge mechanism; when working, after the side flange mechanism of the center grid and the two lamp mouth corner flange mechanisms rotate clockwise for 25° at the same time, the two side flange mechanisms rotate clockwise for 15°. The present invention can realize side flanging in three directions in one station, and can optimize two-step flanging into one-step flanging in the process of stamping process layout, optimize process arrangement, and save development cost.

Description

technical field [0001] The invention relates to the technical field of flanging of the outer plate of the engine cover, in particular to a novel linked rotating wedge. Background technique [0002] In the existing automobile industry, in order to realize automated production and improve production efficiency, many automobile factories have adopted double production in the development of panel molds to achieve one mold with two pieces. The main form is the double assembly of the left and right doors, the double assembly of the left and right fenders, and the double assembly of the inner and outer panels of the engine cover. When developing the double assembly mold for the inner and outer panels of the engine cover, the number of processes for the inner panel is three sequences, and the process for the outer panel is four sequences. , from the perspective of development cost, it is necessary to optimize the number of outer plate processes and reduce it to three-sequence develo...
