Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat treatment equipment, in particular to a device for automatically laying long bolts in a mesh belt furnace. Background Art
[0002] In the production of fasteners, the commonly used equipment in the heat treatment process is the controlled atmosphere continuous mesh belt furnace production line, in which the height allowed to pass between the mesh belt surface at the entrance of the quenching furnace and the upper edge of the furnace entrance is usually 100mm, and the product paving thickness is usually not less than 80mm. In this way, due to the irregular paving of long-rod bolts and screws, some products often tilt up at one end. In order to avoid the furnace being stuck, the feeding weight is often 1 / 3 less than that of short bolts at the same time, so the production efficiency of the heat treatment furnace cannot be fully utilized. In order to improve the production efficiency of long-rod bolts in mesh belt heat treatment furnaces, some factories will arrange workers to manually arrange the long bolts next to the mesh belt, place them neatly on the mesh belt, and then press them flat with a plate. The placement method is 90° to the forward direction of the mesh belt, and they are placed as tightly as possible to prevent the long-rod bolts from tilting up.
[0003] In order to prevent workers from laying materials, some factories now use the vibrating plate of the material to vibrate at high speed to make the long-rod bolts and screws lay materials in the same direction as much as possible. However, due to the irregular laying of bolts, some products often have one end tilted up, and the input weight is too small.
[0004] The way workers place materials next to the mesh belt requires strong endurance in front of the high-temperature furnace, but workers cannot withstand such a high-temperature environment for a long time and it is difficult to carry out.
[0005] The material spreading method uses a vibrating plate with high speed vibration. This method cannot completely achieve neat placement. Some products will be disordered, one end will be tilted, and there will be large gaps between products. The feeding speed is often 1 / 2 less than that of short bolts. The production efficiency of the heat treatment furnace is low.
[0006] In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
