Description

Technical Field

[0001] The utility model relates to the technical field of precision forging combined with tooth cold back taper error prevention, in particular to a device for precision forging combined with tooth cold extrusion to prevent back taper from tilting. Background Art

[0002] Precision forging combined with tooth cold extrusion to prevent back taper is a specific manufacturing process designed to ensure that the tooth-shaped components maintain accurate geometry during processing and prevent the problem of back taper. Usually, during precision forging and cold extrusion, the accuracy and stability of the tooth-shaped components are ensured by precisely designing the die.

[0003] The existing combined tooth-cooled inverted cone error-proofing process uses manual placement of parts into the mold. The worker placing the parts into the mold needs to perform three actions: rotating the product without moving it, pressing the product in the inverted cone mold without tilting it, and listening to the "nailing" sound of the product falling into the inverted cone mold.

[0004] However, the existing method results in low inverse cone production efficiency, and if workers do not perform the work according to standard operating procedures, defective products such as inverse cone pressing and tilting will be produced. Utility Model Content

[0005] The utility model aims to provide a device that combines precision forging with tooth cold extrusion to prevent the cone from being tilted, thereby solving the problem that the existing method leads to low production efficiency of the cone and defective products such as tilted cone will be produced if the workers fail to perform the standard operations.

[0006] To achieve the above-mentioned purpose, the utility model provides a device for preventing the inverted cone from being pressed and tilted by combining precision forging with cold extrusion of teeth, including an inverted cone die seat, a detection component and an installation component;

[0007] The detection component includes an inverted cone mold spring seat, an inverted cone mold lower spring, an inverted cone slide groove and a monitoring component. The inverted cone mold spring seat is fixedly connected to the inverted cone mold seat and is located on the inner wall of the inverted cone mold seat; one end of the inverted cone mold lower spring abuts against the inverted cone mold spring seat, and the other end abuts against the inverted cone slide groove. The inverted cone mold lower spring is located at the top of the inverted cone mold spring seat, the monitoring component is connected to the inverted cone slide groove, and the mounting component is connected to the inverted cone mold seat.

[0008] Among them, the monitoring component includes an inverted cone mold top rod and a displacement sensor, the inverted cone mold top rod is connected to the inverted cone slide groove and is located inside the inverted cone slide groove; the number of the displacement sensors is three, and the three displacement sensors are respectively connected to the inverted cone mold top rod.

[0009] Among them, the installation assembly includes an inverted cone mold sleeve and an inverted cone mold sleeve, the inverted cone mold sleeve is fixedly connected to the inverted cone mold base and is located on the top of the inverted cone mold base; the inverted cone mold sleeve is fixedly connected to the inverted cone mold sleeve and is located on the inner wall of the inverted cone mold sleeve.

[0010] Wherein, the installation assembly also includes an inverted cone mold, which is connected to the inverted cone slide groove and is located above the inverted cone slide groove.

[0011] Wherein, the monitoring component further includes a displacement sensor cable and a displacement sensor amplifier, and the displacement sensor cable is connected to the displacement sensor and the displacement sensor amplifier respectively.

[0012] The utility model discloses a device for preventing the inverted cone from being tilted by combining precision forging with tooth cold extrusion. When the inverted cone is extruded, the workpiece is placed in the inverted cone mold equipped with the displacement sensor. When the workpiece is placed in the inverted cone mold, the flatness detected by the displacement sensor exceeds the set detection accuracy of 0.1mm. The displacement sensor transmits a signal to the displacement sensor amplifier. The displacement sensor amplifier detects a flatness of ≤0.1mm and determines it as qualified. The equipment can be pressed normally. If the displacement sensor amplifier detects a flatness of >0.1mm and determines it as unqualified, the equipment stops pressing at this time, eliminating three actions of manual placement and improving the production efficiency of the inverted cone. If the worker fails to perform the actions according to the standard operation, the product is placed in the inverted cone mold at an angle, and the equipment switch is started, the equipment does not move, which can effectively prevent the generation of defective products caused by the inverted cone being tilted.
