Hoisting inclined wedge with detachable stop block

Abstract

The invention discloses a hoisting inclined wedge with a detachable stop block. The hoisting inclined wedge comprises a base assembly, a sliding block assembly and a driving assembly; the base assembly comprises a base and a limiting side plate, a sliding groove is formed in the base, the stop block is detachably arranged at the open end of the sliding groove, and a buffer is arranged on the stopblock; the sliding block assembly comprises a sliding block and a spring; sliding guide structures are arranged between the top face of the sliding block and the bottom face of the sliding groove andbetween the two side faces and the two side faces of the sliding groove; the stop block is provided with a stop boss and a nut seat, and the nut seat is fixed on the base through a screw; the stop boss is arranged at the upper part of the stop block, is mounted in a groove in the base in a matched manner, and can bear component force in the horizontal or vertical direction; and the driving assembly comprises a driving block, and the sliding block and the driving block are guided through a first V-shaped guide plate and a second V-shaped guide plate. The hoisting inclined wedge has the advantages of being convenient to disassemble and assemble, capable of bearing large impact force and lateral force and the like.

Description

technical field [0001] The invention relates to a wedge, in particular to a lifting wedge with a detachable stop block. Background technique [0002] The wedge mechanism is a mechanical mechanism that changes vertical motion into horizontal motion or inclined motion, and is widely used in the mold industry. As molds become more and more mature in the automobile manufacturing industry, the mold cost and quality control requirements are also getting higher and higher, and then the space occupation of the wedge, the carrying capacity (including punching force, lateral force, stamping speed and wedge material) , strength, etc.), the size of the working face, the size of the return force, and the convenience of wedge maintenance, etc., put forward higher requirements. [0003] Such as figure 1 As shown, the existing cam mechanism currently on the market is generally composed of three parts: a base assembly 100 , a slider assembly 200 and a drive assembly 300 . Wherein, the upp...

Problems solved by technology

[0004] The above-mentioned structure has the advantages of simple structure, easy processing, and high punching force, but it also has the following disadvantages: 1) Due to the limiting effect of the concave chute, the slider cannot be removed from the rear along the sliding direction, which brings inconvenience to the wedge maintenance. Inconvenient; 2) The slide block is only equipped with a sliding surface on the bottom surface, which cannot bear the lateral force; 3) The height of the driving component is too high, the manipulator cannot pass through, or needs to go around; 4) The installation surface of the pressing end of the slide block is small, It cannot meet the requirements of the mold for installing more tools on the wedge; 5) The stroke of the slider is designed according to ST (the sliding distance of the slider along the sliding surface of the base) as an integer, resulting in the working stroke of the slider WT (sliding distance) calculated based on the triangular relationship The sliding distance of the block along the drive block) is a decimal, which is inconvenient for customers to use, and it is easy to accumulate errors due to decimal rounding
