Device and method for preventing sand box from retrograding

Abstract

The invention relates to a device and method for preventing a sand box from retrograding and belongs to the field of engineering construction. The device comprises a roller bed, a roller bed frame, aplurality of rollers, a pin shaft seat, a pin shaft and a stop block. The plurality of rollers are arranged on the roller bed frame. The roller bed used for conveying the sand box is arranged on the roller bed frame. The pin shaft seat is fixed to the roller bed. The pin shaft is arranged on the pin shaft seat. The stop block is provided with a stop block vertical surface and a stop block inclinedsurface. The stop block is movably arranged on the pin shaft. The device is simple and reasonable in structure design, safe, reliable, convenient to operate and low in cost and can achieve the accurate positioning effect on the sand box and meet usage requirements.

Description

technical field [0001] The invention relates to a device and a method, in particular to a device and a method for preventing a sand box from running backward, which belongs to the field of engineering construction. Background technique [0002] During the casting production process, when the sand box is walking on the roller table, when it hits the sand box or baffle in front of it, it will have a rebound retrograde phenomenon, which will cause the sand box to lose its position and affect the automatic operation of the equipment. [0003] The publication date is May 3, 2019, and the Chinese patent with the publication number 208814177U discloses a utility model patent named "a sand box pushing device". The patent includes push cylinder, optical axis guide rail, support bearing, push material bracket, sand box, self-aligning block, through hole, connecting rod and push rod. A push cylinder is installed on one side of the optical axis guide rail, and one end of the push cylind...

AI Technical Summary

Problems solved by technology

The patent includes push cylinder, optical axis guide rail, support bearing, push material bracket, sand box, self-aligning block, through hole, connecting rod and push rod, one side of the optical axis guide rail is equipped with a push cylinder, and one end of the push cylinder is installed There is a push rod, a pushing bracket is installed inside the optical axis guide rail, and one end of the pushing bracket is connected to the push rod, a support bearing is installed at the bottom of the optical axis guide rail, a sand box is installed at the top of the optical axis guide rail, and an automatic pendulum is installed inside the pushing material bracket. Positive block, there is a through hole on the outside of the self-aligning block, and a connecting rod is arranged inside the through hole. Although the patent uses high-pressure air as the power source, the pushing structure is simple and ingenious. The self-aligning block automatically aligns itself after returning The block will not make the sand box move, and at the same time it will be automatically aligned, so as to realize the step-by-step push of the molding sand box; but the structure is relatively complicated and the cost is high, and the sand box cannot be accurately positioned, so it still has the above defects
