Description

Technical Field

[0001] This invention relates to the field of precision forging combined teeth cold taper anti-misalignment technology, and in particular to a device and method for preventing the taper from tilting under cold extrusion of precision forging combined teeth. Background Technology

[0002] Precision forging combined with cold extrusion to prevent tapered misalignment is a specific manufacturing process designed to ensure that toothed components maintain precise geometry during machining, preventing misalignment caused by the tapered shape. Typically, precision forging and cold extrusion involve precisely designed dies to ensure the accuracy and stability of the toothed components.

[0003] The existing combined toothed cold inverted cone anti-misalignment process uses manual placement of parts into the mold. The worker placing the part into the mold needs to perform three actions: rotate the product without moving it, press the product into the inverted cone mold without it tilting, and listen to the "nail" sound of the product falling into the inverted cone mold.

[0004] However, the existing method results in low production efficiency for inverted cones, and if workers do not perform the work according to the standard operating procedures, defective products with skewed inverted cones will be produced. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for preventing the inverted cone from tilting due to precision forging combined with cold extrusion. This solves the problem that existing methods result in low production efficiency of inverted cones, and that defective products with tilted inverted cones will be produced if workers do not perform the work according to the standard operating procedures.

[0006] To achieve the above objectives, the present invention provides a device for preventing the inverted cone from tilting when precision forging combined with cold extrusion, including an inverted cone die base, a detection component, and an installation component; The detection assembly includes an inverted conical mold spring seat, an inverted conical mold lower spring, an inverted conical slide groove, and a monitoring component. The inverted conical mold spring seat is fixedly connected to the inverted conical mold seat and is located on the inner wall of the inverted conical mold seat. One end of the inverted conical mold lower spring abuts against the inverted conical mold spring seat, and the other end abuts against the inverted conical slide groove. The inverted conical mold lower spring is located at the top of the inverted conical mold spring seat. The monitoring component is connected to the inverted conical slide groove, and the mounting assembly is connected to the inverted conical mold seat.

[0007] The monitoring component includes an inverted conical mold ejector rod and displacement sensors. The inverted conical mold ejector rod is connected to the inverted conical groove and is located inside the inverted conical groove. There are three displacement sensors, and each of the three displacement sensors is connected to the inverted conical mold ejector rod.

[0008] The mounting assembly includes an inverted conical mold sleeve and an inverted conical mold cone sleeve. The inverted conical mold sleeve is fixedly connected to the inverted conical mold base and is located on the top of the inverted conical mold base. The inverted conical mold cone sleeve is fixedly connected to the inverted conical mold sleeve and is located on the inner wall of the inverted conical mold sleeve.

[0009] Wherein, the installation component further includes an inverted cone mold, and the inverted cone mold is connected to the inverted cone chute and is located above the inverted cone chute.

[0010] Wherein, the monitoring component further includes a displacement sensor cable and a displacement sensor amplifier, and the displacement sensor cable is respectively connected to the displacement sensor and the displacement sensor amplifier.

[0011] A method for preventing the inverted cone from being pressed obliquely in the cold extrusion of precision forging combined teeth includes the following steps: Install the equipment for preventing the inverted cone from being pressed obliquely in the cold extrusion of precision forging combined teeth; Place the workpiece into the inverted cone mold. At this time, the displacement sensor detects that the flatness exceeds the set detection accuracy of 0.1 mm, and the displacement sensor transmits a signal to the amplifier. The amplifier determines whether it is qualified or unqualified. If it is qualified, the equipment can press normally. If it is unqualified, the equipment stops pressing.

[0012] For the equipment and method for preventing the inverted cone from being pressed obliquely in the cold extrusion of precision forging combined teeth of the present invention, when extruding the inverted cone, place the workpiece into the inverted cone mold equipped with the displacement sensor. When the workpiece is placed into the inverted cone mold, the displacement sensor detects that the flatness exceeds the set detection accuracy of 0.1 mm, and the displacement sensor transmits a signal to the displacement sensor amplifier. The displacement sensor amplifier determines that it is qualified when the detected flatness ≤ 0.1 mm, and the equipment can press normally. If the displacement sensor amplifier detects that the flatness > 0.1 mm, it is determined as unqualified. At this time, the equipment stops pressing, saving the three actions of manual workpiece placement, improving the production efficiency of the inverted cone. If the worker does not perform according to the operation standard actions and the product is placed obliquely into the inverted cone mold and the equipment switch is started, the equipment has no action, effectively preventing the generation of defective products with the inverted cone pressed obliquely.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The first embodiment of this application is as follows: Please see Figure 1 ,in, Figure 1 This is a schematic diagram of the structure of the device for preventing the oblique shape of the inverted cone during cold extrusion of precision forged teeth according to the first embodiment of the present invention. The present invention provides a device for preventing the oblique shape of the inverted cone during cold extrusion of precision forged teeth: it includes an inverted cone die base 101, a detection component and an installation component. The detection component includes an inverted cone die spring seat 102, an inverted cone die lower spring 103, an inverted cone slide groove 104 and a monitoring component. The monitoring component includes an inverted cone die top rod 105, a displacement sensor 106, a displacement sensor cable 110 and a displacement sensor amplifier 111. The installation component includes an inverted cone die sleeve 107, an inverted cone die cone sleeve 108 and an inverted cone mold 109.

[0019] In this specific embodiment, the inverted conical mold spring seat 102 is fixedly connected to the inverted conical mold seat 101 and is located on the inner wall of the inverted conical mold seat 101; one end of the inverted conical mold lower spring 103 abuts against the inverted conical mold spring seat 102, and the other end abuts against the inverted conical slide groove 104; the inverted conical mold lower spring 103 is located at the top of the inverted conical mold spring seat 102; the monitoring component is connected to the inverted conical slide groove 104; and the mounting component is connected to the inverted conical mold seat 101.

[0020] The inverted conical die spring seat 102 is installed into the inverted conical die seat 101, and then the inverted conical die lower spring 103 is installed into the inverted conical die spring seat 102. The inverted conical slide groove 104 is installed on the inverted conical die lower spring 103.

[0021] The inverted cone mold ejector rod is connected to the inverted cone slide groove 104 and is located inside the inverted cone slide groove 104; there are three displacement sensors 106, and the three displacement sensors 106 are respectively connected to the inverted cone mold ejector rod 105.

[0022] The copper sleeve is inserted into the inverted conical mold ejector rod 105, and then the displacement sensor 106 is inserted into the copper sleeve and tightened with an internal hexagon head screw. Three displacement sensors 106 are evenly installed in the inverted conical mold ejector rod 105. The three displacement sensors 106 are evenly distributed circumferentially along the inverted conical mold ejector rod 105. The effect of the circumferential distribution is to detect the flatness of the product at three evenly distributed points. Then, the inverted conical mold ejector rod 105 with the three displacement sensors 106 installed is installed in the inverted conical slide groove 104.

[0023] Secondly, the inverted conical mold sleeve 107 is fixedly connected to the inverted conical mold base 101 and is located at the top of the inverted conical mold base 101; the inverted conical mold cone sleeve 108 is fixedly connected to the inverted conical mold sleeve 107 and is located on the inner wall of the inverted conical mold sleeve 107. The inverted conical mold 109 is connected to the inverted conical slide groove 104 and is located above the inverted conical slide groove 104.

[0024] The inverted cone mold sleeve 107 is used for support, the inverted cone mold sleeve 108 is located outside the detection component and plays a protective role, and the inverted cone mold 109 is installed on the inverted cone slide groove 104.

[0025] Meanwhile, the displacement sensor cable 110 is connected to the displacement sensor 106 and the displacement sensor amplifier 111 respectively.

[0026] The displacement sensor amplifier 111 is installed inside the hydraulic press and connected to the displacement sensor 106 via the displacement sensor cable 110. The displacement sensor cable 110 is used to transmit signals. The hydraulic cylinder push rod 113 is located below the inverted cone mold push rod 105. After pressing, it pushes open the mold to facilitate the removal of the workpiece.

[0027] Using the precision forging combined with cold extrusion device for preventing the inverted cone from tilting, the detection accuracy on the device display screen is set to 0.1mm. A standard part is placed into the inverted cone mold 109, and then the comparison value input button is pressed on the data interface of the display screen. At this time, the zero point calibration is completed. When extruding the inverted cone, the workpiece 112 is placed into the inverted cone mold 109 equipped with the displacement sensor 106. When the workpiece 112 is placed into the inverted cone mold 109, the displacement sensor 106 detects that the flatness exceeds the set detection accuracy of 0.1mm. The displacement sensor 106 transmits a signal to the displacement sensor amplifier 111. The displacement sensor amplifier 111 determines whether it is qualified or unqualified. If it is qualified, the device can press normally, eliminating the three manual actions of placing the part, thus improving the production efficiency of the inverted cone. If the worker does not perform the operation according to the standard operation, the product is placed into the inverted cone mold 109 at an angle. When the device is turned on, the device does not operate, which can effectively prevent the production of defective products with tilted inverted cones.

[0028] The second embodiment of this application is as follows: Based on the first embodiment, please refer to Figure 2 ,in, Figure 2 This is a flowchart illustrating the steps of a method for preventing the oblique shape of a reverse cone through cold extrusion of precision-forged combined gears according to a second embodiment of the present invention. The method for preventing the oblique shape of a reverse cone through cold extrusion of precision-forged combined gears according to this embodiment includes the following steps: S201: Install the equipment to prevent the reverse cone from tilting due to cold extrusion of precision forged teeth; S202: Place the workpiece 112 into the inverted cone mold 109. At this time, the displacement sensor 106 detects that the flatness exceeds the set detection accuracy by 0.1mm, and the displacement sensor 106 transmits a signal to the amplifier. S203: The amplifier is judged as qualified or unqualified. If the equipment is qualified, it can suppress the circuit normally. If the equipment is unqualified, it will stop suppressing the circuit.

[0029] Specifically, first, the inverted conical die spring seat 102 is installed into the inverted conical die seat 101, then the inverted conical die lower spring 103 is installed into the inverted conical die spring seat 102, and the inverted conical slide groove 104 is installed on the inverted conical die lower spring 103; the copper sleeve is installed into the inverted conical die ejector rod 105, then the displacement sensor 106 is installed into the copper sleeve and tightened with an internal hexagon head screw, and three displacement sensors 106 are evenly installed into the inverted conical die ejector rod 105; then the inverted conical die ejector rod 105 with the three displacement sensors 106 installed is installed into the inverted conical slide groove 104, and finally the inverted conical die 109 is installed on the inverted conical slide groove 104. The displacement sensor amplifier 111 is installed into the hydraulic press equipment, the detection accuracy on the equipment display screen is set to 0.1mm, the standard part is placed into the inverted conical die 109, and then the comparison value input button is pressed on the data interface of the display screen. At this time, the zero point calibration is completed. During the extrusion of the inverted cone, the workpiece 112 is placed into the inverted cone mold 109 equipped with the displacement sensor 106. When the workpiece 112 is placed into the inverted cone mold 109, the displacement sensor 106 detects that the flatness exceeds the set detection accuracy by 0.1mm. The displacement sensor 106 transmits a signal to the displacement sensor amplifier 111, which determines whether the workpiece is qualified or unqualified. If the workpiece is qualified, the equipment can press normally; if the workpiece is unqualified, the equipment stops pressing. This eliminates the three manual actions of placing the workpiece, improving the production efficiency of the inverted cone. If the worker does not follow the standard operating procedure and places the product at an angle into the inverted cone mold 109, the equipment will not operate when the switch is turned on, effectively preventing the production of defective products with skewed inverted cones.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
