Detailed Description

The technical solution of the present invention is further described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1 to 4, a tempering furnace for automatically feeding and discharging long-handle parts and a use method thereof comprise a tempering furnace 1, wherein a feeding manipulator 2 is arranged on one side of a feeding port of the tempering furnace 1 and used for feeding the tempering furnace 1, and a discharging manipulator 3 is arranged on one side of a discharging port of the tempering furnace 1 and used for discharging the tempering furnace 1. The tempering furnace 1 heats and tempers the workpiece placed inside through the heating coil 13 in the inner wall in the working process, and the workpiece is transported out after tempering. In the non-operating state, the oven door is opened and the top fan 14 is replaced with the outside air, so that the oven is slowly cooled down.

A conveying mesh belt 12 is arranged in the inner cavity of the tempering furnace 1, and a transmission device 11 for driving the conveying mesh belt 12 to run is arranged at the bottom of the tempering furnace 1. The transmission device 11 generally adopts a motor to drive a chain wheel to rotate, and then drives the conveying mesh belt 12 to circularly convey in the tempering furnace 1, and the transmission device 11 and the conveying mesh belt 12 are the prior art and are not repeated in detail here.

The conveying net belt 12 is evenly provided with a plurality of clamping plates 15 for clamping and supporting the long handle of the long handle part 4, when the conveying net belt 12 is used, the clamping plates 15 are vertically arranged on the conveying net belt 12 in a plurality of rows, and the clamping plates 15 in each row are mutually connected in series. The plurality of clamping plates 15 are connected in series with each other along the conveying direction of the conveying mesh belt 12, and a plurality of rows can be arranged according to the width of the conveying mesh belt 12. The long handle of the long handle part 4 is clamped in the groove 16 at the top of the clamping plate 15, and at least two clamping plates 15 are generally needed to support the long handle part 4.

Referring to fig. 5, a groove 16 is formed at the top of the card board 15. As a preferable scheme, the groove 16 is any one of a semicircular groove, an arc-shaped groove, a V-shaped groove, a U-shaped groove, and a bevel edge flared groove, and can support the long-handled component 4, specifically, a shank rod with a small diameter in a workpiece of the long-handled component 4 is placed in the groove 16.

s1: when the long-handle parts quenched by the intermediate frequency quenching machine tool are conveyed to a feeding hole of a tempering furnace, the feeding manipulator is opened to transversely place the long-handle parts on the static conveying mesh belt. When long handle spare part work piece is placed, the quiescent time of conveying guipure is 1 ~ 2 minutes, because the beat of intermediate frequency quenching lathe is about 60 seconds and carries out a long handle spare part, and two work pieces of output need about 2 minutes, consequently for the convenience of material loading manipulator place the work piece, the guipure is stopped motionless this moment.

S2: after the workpieces on each longitudinal conveying mesh belt are placed, the PLC system controls the transmission device to drive the conveying mesh belts to operate, the conveying mesh belts move forwards to a next workpiece placing station, then the conveying mesh belts stop operating, and a feeding manipulator waits for placing long-handle part workpieces. Two long-handle part workpieces are placed on each longitudinal conveying mesh belt, and long-handle rods of the two long-handle part workpieces are positioned on the inner side of the conveying mesh belt.

S3: when the long-handle parts tempered by the tempering furnace are conveyed to a discharge hole of the tempering furnace, the discharging manipulator is opened to clamp the long-handle parts away from the static conveying mesh belt and place the long-handle parts in the next procedure. When the long-handle part workpiece is clamped away, the static time of the conveying net belt is the same as the time when the long-handle part workpiece is placed, and the common operation time is provided. Because the discharging mode of the discharging port is that the mesh belt pause time of about 2 minutes is generated when the feeding manipulator of the feeding port places two workpieces in the discharging process, the discharging manipulator of the discharging port clamps away the workpieces transversely placed on the conveying mesh belt within the 2 minutes, and the workpieces enter the next process, so that a full-automatic production mode is formed.

The feeding and discharging operations of the tempering furnace are automatically completed by the mechanical arm, the whole process does not need personnel operation, and a large amount of labor cost is saved for enterprises. And the interference of human factors in the production process is reduced through the full-automatic control of the PLC. On the basis of the plane conveying mesh belt 12, a plurality of rows of clamping plates 15 which are connected together are added in the tempering furnace, and the long-handle parts 4 are supported through the grooves 16 at the tops of the clamping plates 15, so that the deformation of the long-handle parts 4 in the tempering process is avoided, and the production quality of the long-handle parts 4 is ensured.

The above-mentioned embodiments, objects, technical solutions and advantages of the present invention are further described in detail, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
