Description

Technical Field

[0001] The utility model relates to a feeding device for a forging billet heating furnace, belonging to the technical field of heating furnaces. Background Art

[0002] Forging is a processing method that uses a forging press to apply pressure to a heated metal blank to cause it to undergo plastic deformation in order to obtain forgings with certain mechanical properties, shapes and sizes. Before forging production, the metal forging blank must first be heated to the forging temperature in a heating furnace. Due to the large variety of forged parts and their different shapes and sizes, the forging blanks also have a variety of shapes and sizes. During forging production, a pusher-type heating furnace is generally used to heat the forging blanks. The pusher-type heating furnace uses a feeding device installed on one side of the furnace, i.e., a steel pusher, to push the forging blanks into the heating furnace one by one to achieve the feeding and unloading of the heating furnace. In order to ensure that the pushing direction is balanced on the left and right, that the pushing direction does not deflect, and that the pushing stroke is precisely controllable, the existing heating furnace's steel pushing mechanism generally uses multiple cylinders for synchronous pushing, or a stepper motor drives the screw for pushing, or a PLC controls the pushing stroke, etc., which results in the heating furnace's feeding device having problems such as complex structure, complex operation, inconvenient maintenance, and high cost. Summary of the invention

[0003] The utility model aims to overcome the above-mentioned shortcomings and provide a feeding device for a forging billet heating furnace which has simple structure, simple operation, convenient maintenance and low cost.

[0004] The purpose of the utility model is achieved in this way:

[0005] A feeding device for a forging billet heating furnace is installed on the outside of a feeding table of the heating furnace, and comprises a base, a thrust cylinder hingedly mounted on the base at the bottom of a fixed end, a guiding mechanism and a stroke adjusting mechanism arranged on the feeding table, and a steel-pushing trolley slidably arranged on the feeding table and guided by the guiding mechanism; the steel-pushing trolley is connected to the movable end of the thrust cylinder and is controlled by the thrust cylinder to move back and forth on the feeding table; a pushing plate for pushing the forging billet forward is provided at the front end of the steel-pushing trolley, and a roller is provided at the rear end; the guiding mechanism comprises baffles arranged at the two side edges of the feeding table for limiting and guiding the two sides of the push plate, and roller grooves arranged in the middle of the feeding table for limiting and guiding the roller.

[0006] Furthermore, the baffle plate and the roller groove are kept parallel to the feed center line of the heating furnace.

[0007] Furthermore, the steel pushing trolley includes a vehicle body connected to the movable end of the propulsion cylinder and a plurality of connecting rods fixed between the vehicle body and the push plate; the roller is rotatably arranged on the vehicle body; and a triangular stable structure is formed between the connecting rods.

[0008] Furthermore, the stroke adjustment mechanism includes a proximity switch installed on the feed table. After the push plate contacts the proximity switch, the proximity switch sends a signal and the propulsion cylinder stops propulsion.

[0009] Furthermore, the propulsion cylinder body is hingedly connected to the bottom of the base with a lifting cylinder, which can lift the propulsion cylinder for easy maintenance and inspection.

[0010] Furthermore, a stabilizing rod is connected between the base and the feeding platform.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model sets a baffle plate and a roller groove with a limiting guiding function on the feeding table of the heating furnace, and limits the movement of the push plate and the roller of the steel pushing trolley respectively, so as to ensure the accurate pushing direction of the steel; and the steel pushing stroke is controlled by setting a proximity switch matched with the push plate. The overall feeding device has a simple structure, simple operation, convenient maintenance and low cost. BRIEF DESCRIPTION OF THE DRAWINGS
