Problems solved by technology

The traditional side wall A-pillar mold includes a punch cover plate fixed on the lower mold base, and a punch that moves relative to the punch cover plate. The punch moves obliquely upwards through the driving block, and then performs shaping work after it is in place. The result of this mechanism Simple, the working angle and retraction stroke of the punch are small, and the scope of use is limited

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 The three-moving wedge device shown in —7 includes a first-level tackle drive block 1; the first-level tackle drive block 1 is fixed with a tilting block 5 towards the side of the first-level tackle, and the end face of the tilting block 5 includes a corner that forms an acute angle with the horizontal plane. The inclined surface and the vertical surface connected with the top of the inclined surface, one end of the first-level tackle 2 towards the first-level tackle driving block 1 is fixed with a first-level tackle moving block 6 cooperating with the inclined block 5, and the end face of the first-level tackle moving block 6 is a vertical plane. The primary pulley drive block 1 moves downward, and the primary pulley 2 moves horizontally toward a direction away from the first pulley drive block 1 .

Abstract

The invention discloses a three-driven wedge device. The three-driven wedge device comprises a first-level pulley drive block, a first-level pulley, a second-level pulley and a third-level pulley, wherein the first-level pulley is driven by the first-level pulley drive block to move horizontally in the direction far away from the first-level pulley drive block; the second-level pulley is driven by the first-level pulley to obliquely move upwards to the outer side of the first-level pulley and is used for processing the pillar A side wall; and the third-level pulley is driven by the first-level pulley to obliquely move upwards to the outer side of the first-level pulley and is used for processing the pillar A depth. The movement tilting angle of the third-level pulley is larger than that of the second-level pulley. Movement direction conversion of the second-level pulley and the third-level pulley is achieved through linear movement of the first-level pulley, the reciprocating stroke of movement is large, and movements among the pulleys do not interfere with one another. The requirements for the pillar A shaping depth and shaping negative angle are guaranteed. The three-driven wedge device is simple, convenient to operate and good in practicability and market application value.

Description

technical field [0001] The invention relates to the technical field of manufacturing equipment for an automobile A-pillar, in particular to a three-moving wedge device. Background technique [0002] The automobile side wall mold is the mold with the highest manufacturing difficulty and processing precision among the panel molds. Among them, the cross-sectional width of the side A-pillar directly affects the driver's line of sight, that is, the larger the width, the larger the blind area of ​​sight and the larger the angle of visual impairment. In today's car design, the width of the A-pillar section is reduced as much as possible, and the depth of the side wall of the A-pillar is increased to reduce blind spots and improve vehicle driving safety. The traditional side wall A-pillar mold includes a punch cover plate fixed on the lower mold base, and a punch that moves relative to the punch cover plate. The punch moves obliquely upwards through the driving block, and then perf...
