Abstract
Description
Technical Field
[0001] The utility model relates to the field of casting production line equipment, in particular to an anti-backsliding device for roller tracks and a sand box transfer system. Background Art
[0002] A casting production line is a combination of a series of equipment and technological processes for producing metal castings. This production line can be customized according to the types, scales, and precision requirements of castings to meet different production needs. Among them, the sand casting production line is one of the most traditional casting production methods, mainly applicable to fields with extensive requirements such as casting large parts, small batches, and irregular parts. It has the advantages of flexible process, short production cycle, low raw material cost, etc. The production process includes multiple links such as sand mold making, melting and casting, cleaning, and grinding.
[0003] During pouring and cooling in the casting production line, the temperature of the sand box is relatively high during and after pouring. A combination of manual roller tracks and a pusher is mostly used. The sand box is placed on a backing plate, and a pusher head of the pusher applies a thrust to the backing plate to achieve pouring and transfer of the sand box on the manual roller track line; the roller track has initial leveling during equipment layout, but as the equipment is used, the roller track may have an inclination. At this time, in order to prevent the sand box that has been pushed in place from sliding back and falling off the roller track due to the inclination of the roller track line under the action of gravity, a structure for restricting the position of the backing plate needs to be added to the roller track.
[0004] The current limiting method is mainly to add a cylinder clamping device to the manual roller track, clamp the two sides of the backing plate, and position the sand box by relying on the friction between the clamping device and the backing plate. However, the phenomenon that the sand box still slides back often occurs due to insufficient friction. Summary of the Invention
[0005] Aiming at the problem that the current friction clamping type positioning structure is prone to insufficient friction, the utility model provides an anti-backsliding device for roller tracks.
[0006] To solve the above problems, the technical solution adopted by the utility model is that an anti-backsliding device for roller tracks includes a base, a turning arm is hingedly installed on the base. The turning arm includes a horizontal section and an inclined section. The horizontal section is hinged to the base. The inclined section is connected to the first end of the turning arm and extends obliquely upward away from the horizontal section. A weight increasing structure is provided at the second end of the horizontal section.
[0007] This solution designs an anti-backsliding device. By means of the weight increasing structure, the turning arm is kept in a flipped-up state. When the sand box backing plate runs forward, it contacts the inclined side of the inclined section and presses down the turning arm to pass through. When backsliding occurs, the end of the inclined section abuts against the sand box backing plate to prevent it from continuing to backslide. This structure is ingeniously designed and realizes anti-reverse by means of hard limit, and the effect is reliable.
[0008] Preferably, the weight increasing structure includes a lower edge section, and the upper end of the lower extension section is fixedly connected to the second end of the horizontal section, so that the center of gravity of the turning arm is located at the lower extension section part.
[0009] Preferably, a counterweight is further provided at the lower part of the lower extension section. By further setting the counterweight, the turning arm can be more sensitive and rapid in flipping and resetting.
[0010] Preferably, a weight-reducing hollow is formed on the inclined section.
[0011] Preferably, a chamfer is provided at the top edge of the second end of the horizontal section.
[0012] Preferably, the top end of the inclined section is rounded. This makes the passing of the sand box backing plate smoother.
[0013] Preferably, two hinge seats are provided on the top surface of the base, a rotating shaft is rotatably installed between the two hinge seats, and the horizontal section is installed in the middle of the rotating shaft and located between the two hinge seats. The articulated rotating shaft adopts a form of two-end support, and has stronger impact resistance.
[0014] On the other hand, the present invention further provides a sand box transfer system, which includes a roller path and a sand box backing plate. The roller path includes a roller path frame and a plurality of supporting rollers arranged on the top surface of the roller path frame. The supporting rollers support the sand box backing plate. The system further includes the above-mentioned anti-backflow device for the roller path. The base is installed on the roller path frame, the turning arm is located between adjacent supporting rollers, along the running direction of the sand box backing plate, the inclined section is located in front of the horizontal section; in the natural state, the upper end of the inclined section is higher than the highest point of the supporting rollers. This system has the above-mentioned anti-backflow device, which can prevent the sand box backing plate from backflow even if a slope appears after long-term use, improving the safety of the equipment.
[0015] Preferably, two anti-backflow devices for the roller path are provided, and the planes where the two turning arms are located are symmetrical about the midpoint of the supporting roller along its own axial direction. The two anti-backflow devices are in contact with both sides of the sand box backing plate, and the forces on both sides of the sand box backing plate are balanced, which can prevent the backing plate from shifting.
[0016] It can be seen from the above technical solutions that the advantages of the present invention are as follows: This solution designs an anti-backflow device for a sand box conveying roller path, which is installed on both sides of the roller path. When the sand box backing plate backflows, a hard limit contact is formed to block the backflow of the sand box backing plate. At the same time, when the sand box backing plate runs forward, the turning arm can be pressed down to enable the sand box backing plate to pass smoothly. This solution has a reliable structure, good anti-reverse effect, and sensitive reset of the turning arm through the design of the center of gravity of the structure; furthermore, the sand box transfer system provided by this solution can ensure stable operation even if a slope is generated, and has higher safety.
