Description

Technical Field

[0001] The utility model relates to the technical field of annealing furnaces, in particular to the technical field of annealing furnace feeding mechanisms. Background Art

[0002] An annealing furnace is a heat treatment furnace primarily used to alter the physical and chemical properties of materials through heating. Depending on the heating method and application scenario, annealing furnaces can be divided into various types, such as electric, oil-fired, and gas-fired. Annealing furnaces generate heat through heating elements, transferring heat to the workpiece within the furnace, annealing the workpiece within a set temperature range. Annealing can reduce or eliminate the hardening of the workpiece during cold working, improving its mechanical and processing properties.

[0003] Existing annealing furnaces require manual feeding and manual positioning of the materials in the furnace, resulting in low work efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to provide an annealing furnace feeding mechanism that can solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model proposes an annealing furnace feeding mechanism, comprising a furnace body, a feed port is provided on the side of the furnace body, a plurality of feed rollers are provided inside the furnace body, the feed rollers are rotatably installed in the furnace body, a bidirectional screw is provided below the feed roller, movable nuts are threadedly installed on both sides of the bidirectional screw, a mounting seat is provided on the movable nut, a threaded hole is provided on the mounting seat, a positioning column is threadedly installed in the threaded hole, the positioning column is arranged in the gap between the feed rollers, a threaded column is provided on the top of the positioning column, a positioning bracket is passed through the threaded column, the positioning bracket is located above the feed roller, and a fastening nut is threadedly installed on the threaded column.

[0006] Preferably, the positioning bracket is provided with a positioning straight bar or an arc-shaped clamping plate.

[0007] Preferably, the bidirectional lead screw is driven to rotate by a drive motor.

[0008] Preferably, a connecting bracket is provided at the feed port, and a plurality of feeding rollers are provided on the connecting bracket.

[0009] Preferably, the connecting bracket is connected to a conveying bracket, and the conveying bracket is provided with a plurality of conveying rollers.

[0010] The beneficial effects of the utility model are as follows: the utility model automatically transports the workpiece into the furnace body through the feed roller, and then rotates the bidirectional screw to make the two positioning brackets approach each other to center the workpiece, eliminating the trouble of manual feeding and manual positioning, and improving work efficiency; the shape of the positioning bracket can be replaced according to different workpieces, and it is more adaptable.

[0011] The features and advantages of the present invention will be described in detail through embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
