Description

The preheating constant temperature oven of wire rope end and anchor head lockset automatic casting system

Technical field

It is specifically a kind of to be automated for wire rope end and anchor head lockset the utility model is related to a kind of preheating constant temperature oven The preheating constant temperature oven of running gate system belongs to steel wire rope deep process technology field.

Background technology

Steel wire rope is that mechanical property and the satisfactory steel wire of geometric dimension are twisted together according to certain rule Helical form steel tendon, steel wire rope is by steel wire, wire rope core and grease composition.Steel wire rope is first to be twisted stock by multilayer steel wire, then with rope Centered on core, helically wound rope is twisted by certain amount stock.Steel wire rope can transmit the load of long range, can bear a variety of The effect of load and varying load has higher tensile strength, fatigue resistance and toughness, be suitable for drawing, pull, It various purposes such as ties up, is widely used in the necks such as metallurgy, mine, petroleum gas drilling, machinery, chemical industry, aerospace Domain.

Steel wire rope as promotion, traction, tension and load bearing component in use, being typically that the both ends of steel wire rope are passed through steel Cord anchor head lockset is connect with other equipment, and the connection type of steel wire rope anchor head lockset and wire rope end usually has cast and folder Tight riveting two ways, wherein the mode poured into a mould is penetrated after breaing up wire rope end in the connecting hole of steel wire rope anchor head lockset So as to there is melting gap, to connecting hole after blocking the connecting hole bottom position of steel wire rope anchor head lockset and preheating between each steel wire Middle casting molten metal (being usually kirsite), steel wire rope is connected as one with steel wire rope anchor head lockset after cooling.

In the prior art, casting process is typically to use manual operation, i.e., will manually wear and connect steel wire rope anchor head lockset It is preheated in wire rope end merging preheating furnace, wire rope end is taken out after being preheated to set temperature and is locked steel wire rope anchor head Tool is worn side by side to be connected on pourer and loads onto so that the cast end face of steel wire rope anchor head lockset is arranged upward, and pouring kettle is then manually used Dip the molten metal in molten bath and the successively casting molten metal into the cast end of steel wire rope anchor head lockset.This traditional people The mode of work operation has the following defects：

1, wire rope end is taken out after preheating and wears steel wire rope anchor head lockset side by side be connected on pourer and load onto, manually pour The process time of note is longer, and temperature reduces the steel wire rope anchor head lockset after preheating easily caused by the operating time is long, and then influences Casting quality, in the lower wire rope end for even needing to connect steel wire rope anchor head lockset to wearing of ambient temperature Again it is preheated；

2, manually the molten metal in molten bath is dipped with pouring kettle and poured successively into the cast end of steel wire rope anchor head lockset The mode of molten metal is noted there are larger security risk, operating personnel are easily burned；

3, not only production efficiency is relatively low for manually-operated mode, but also the human factors such as the technical ability of operating personnel and sense of responsibility It is affected to manufacturing schedule and quality；

4, the fire door of common preheating furnace is typically conventional rectangular configuration, due to being placed in the related steel wire for having steel wire rope Steel wire rope is exposed to outside fire door after line anchor head lockset, therefore causes fire door that can not be completely closed because of the blocking of steel wire rope, in turn Cause that pre-heating temperature elevation is slow, preheating is less efficient.

Invention content
