Description

Technical Field

[0001] The present invention relates to the technical field of edge machining, and specifically to an electromagnetic induction numerically controlled edge forging and forming machine. Background Art

[0002] Traditional cutting machining only forms the edge shape and cannot make any changes to the performance of the edge itself. Forging technology can cause plastic deformation in corresponding parts of the workpiece to obtain better performance. Among them, the disc edge is usually prepared by hot spinning, and it is the latest process for forming a rotating disc without cutting. However, how to achieve further breakthroughs in the performance of the disc edge when the conventional performance of the raw material reaches its limit is a problem that needs to be considered, so as to further improve various performance indicators of the edge and achieve the purpose of improving wear resistance and service life.

[0003] Existing edge forging devices generally only target tool edges. For example, a die pressing and forming tool edge forging device and its implementation method are disclosed in Patent No. CN114393169B. On one side of the upper end of the device body, there is an extension table. The upper surface of the extension table is provided with a lifting cylinder. The output end of the lifting cylinder penetrates the extension table and is fixedly connected to a moving plate. On the device body below the extension table, there is a processing table. The upper surface of the processing table is provided with a fixing groove, and one side of the fixing groove is connected to a rotating groove. This device preliminarily fixes the position of the tool back by movably connecting a pressing plate in the rotating groove. And a traction rope and a tension spring are arranged on the upper surface of the pressing plate. It uses the moving plate to drive the traction rope and the tension spring to move, realizes the rotation of the pressing plate and applies pressure to the tool to clamp the tool back, thereby preventing the tool from shifting. However, this device is not applicable to the above-mentioned rotating disc. The circumferential edge of the rotating disc is provided with disc edges, and it cannot be fixed by the above mechanism. At the same time, it is also impossible to apply pressure to the edge through conventional hammers, anvils, punches, etc. to cause plastic deformation. Summary of the Invention

A right-angle reduction gearbox is provided on the lower mounting part, and the power output end on the upper side of the right-angle reduction gearbox is connected to the lower pressing plate, and the power input end at the lower end is connected to a motor arranged on one side of the pressing mounting seat.

[0008] The electromagnetic heating mechanism includes a heating support and a heating moving module. The heating support is designed in an inverted concave shape, and the motor in the pressing mechanism is arranged in the heating support. The heating moving module is arranged on the heating support, and the electromagnetic heating element is driven to move by the heating moving module.

[0009] The electromagnetic heating element includes two arc-shaped heating parts arranged up and down and having a curvature matching the outer circumference of the rotary body disc. A heating slot is formed between the two arc-shaped heating parts, and the edge of the rotary body disc is inserted into the heating slot. In addition, coil side plates are provided on both sides of the electromagnetic heating element, and side plate slots are provided on the coil side plates to connect with the heating slot. A coil lead connecting plate is provided on any one of the coil side plates.

[0010] The heating moving module is provided with a heating moving seat. An installation plate is provided at the rear side of the middle part of the electromagnetic heating element, and the installation plate is installed on the heating moving seat.

[0011] The pressing mechanism includes a pressing mounting base. The centering mechanism includes guide shafts on both sides, and a fixing block is provided in the middle of the guide shafts and fixed on the pressing mounting base. A centering cylinder is provided between the two guide shafts, and the rear end of the cylinder body of the centering cylinder is fixed on the pressing mounting base. The power shaft end of the centering cylinder is fixedly connected to a driving connecting plate, and each end of the guide shaft passes through the driving connecting plate. Driving rods are provided on both sides of the driving connecting plate. Movable centering blocks are sleeved at both ends of the guide shafts, and the driving rods are connected to the adjacent centering blocks. A cross-link assembly is provided outside the guide shafts, and the middle of the cross-link assembly is mounted on the fixing block on the corresponding side. The two ends of the cross-link assembly are respectively connected to the centering blocks on the corresponding side.

[0012] The forging mechanism includes a forging mounting base. An elevating slider and a fixing block are provided inside the forging mounting base. The upper forging wheel is arranged on the elevating slider, and the lower forging wheel is arranged on the fixing block. A forging cylinder is provided at the upper end of the forging mounting base, and the elevating slider is driven to move up and down by the forging cylinder.

[0013] The forging feeding mechanism includes a forging moving base, a forging feeding motor, and a forging feeding lead screw.

[0014] The pressing mechanism, the electromagnetic heating mechanism, and the forging feeding mechanism are all arranged on a base, and the centering mechanism is arranged on the pressing mechanism.

[0015] The rotary body disc is first placed on the lower pressing disc, and then the rotary body disc is clamped and positioned by the centering blocks in the centering mechanism. Then, the upper pressing disc descends to cooperate with the lower pressing disc to clamp and limit the axial displacement. Then, the electromagnetic heating element in the electromagnetic heating mechanism moves forward to one side of the rotary body disc. Then, the rotary body disc is driven to rotate by the lower pressing disc, and the cutting edge is heated by the electromagnetic heating element. After heating to the set temperature, the rotary body disc continues to rotate driven by the lower pressing disc, and the forging mechanism is driven to move forward by the forging feeding mechanism and the other side of the rotary body disc enters between the upper forging wheel and the lower forging wheel. After the heated cutting edge enters the forging mechanism, it is continuously forged by the upper forging wheel and the lower forging wheel, and the electromagnetic heating element on the other side remains in the heating state.

[0016] The advantages and positive effects of the present invention are:

[0017] 1. The present invention is designed for a rotating disk. The pressing mechanism can not only ensure the axial limit of the rotating disk, but also the lower pressing disk in the pressing mechanism can drive the rotating disk to rotate. Thus, on the one hand, the cutting edge of the rotating disk can be switched between the electromagnetic heating mechanism and the forging mechanism, and on the other hand, during electromagnetic heating or forging, the rotating disk can also rotate in cooperation.

[0018] 2. The present invention uses electromagnetic induction heating to reduce the pressure required for the deformation of the cutting edge of the rotating disk, and in cooperation with the rotation of the rotating disk body and the action of the upper and lower forging wheels of the forging mechanism, the cutting edge is pressurized and undergoes continuous point-by-point deformation, thereby achieving further breakthroughs in the performance of the cutting edge.

[0019] 3. The structural design of the electromagnetic heating element of the present invention can ensure that all-round uniform heating is achieved at the positions related to the cutting edge, with high thermal efficiency and fast thermal startup, and at the same time, the temperature control is more accurate. In addition, side plate slots are provided on the coil side plates on both sides of the electromagnetic heating element for the cutting edge of the rotating disk to pass through, which does not affect the lower pressing disk to drive the rotating disk to rotate. In addition, an installation plate is provided at the rear side of the middle part of the electromagnetic heating element of the present invention and is installed on the heating moving seat. In this way, the present invention can replace a suitable electromagnetic heating element according to the specifications of the rotating disk to be processed, which improves the flexibility and application range of the present invention.

[0020] 4. Before processing, the present invention uses a centering mechanism to clamp, extrude and position the rotating disk, so as to ensure accurate positioning of the rotating disk. The centering mechanism uses the opening and closing movement of each group of cross rods in the cross-link rod assembly to realize the synchronous opening and closing movement of the centering blocks on both sides. Since the opening and closing angles of each group of cross rods are the same, it is convenient for the equipment control system to analyze and calculate and accurately control the displacement of each centering block, thereby avoiding excessive displacement of the centering block resulting in a large clamping force that damages the workpiece, or too small displacement without achieving the centering and positioning effect.

[0021] 5. The guide shafts and the cross-link rod assembly on both sides of the centering mechanism of the present invention can be respectively arranged in the gaps between the electromagnetic heating mechanism and the pressing mounting seat and between the forging feed mechanism and the pressing mounting seat, so that the overall structure of the present invention is compact and does not occupy too much installation space. In addition, the heating support in the electromagnetic heating mechanism is designed in an inverted concave shape, so that the motor in the pressing mechanism can be arranged in the heating support, thereby further ensuring the compactness of the overall structure of the present invention. In this way, each mechanism of the present invention can be integrally arranged on a base, which is convenient for overall transfer.

[0022] 6. Both the electromagnetic heating mechanism and the forging feed mechanism of the present invention are driven by a motor and a lead screw to move, so that the moving distances of the electromagnetic heating element and the forging mechanism can be accurately controlled to ensure accurate cooperation with the rotating disk.

Detailed implementation mode

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] As Figures 1-10 shown, the present invention includes a pressing mechanism 5, a centering mechanism 2, an electromagnetic heating mechanism 6, a forging mechanism 4, and a forging feed mechanism 3. Among them, as Figure 2 shown, the pressing mechanism 5 includes a liftable upper pressing plate 501 and a rotatable lower pressing plate 502, and the rotating body disc 7 is clamped and fixed by the upper pressing plate 501 and the lower pressing plate 502. As Figure 1 shown, the electromagnetic heating mechanism 6 is arranged on one side of the lower pressing plate 502, and the electromagnetic heating mechanism 6 is provided with a movable electromagnetic heating element 601. The forging mechanism 4 and the forging feed mechanism 3 are arranged on the other side of the lower pressing plate 502, and the forging mechanism 4 is driven to move by the forging feed mechanism 3. Among them, as Figure 5 shown, the forging mechanism 4 includes a liftable upper forging wheel 402 and a fixed lower forging wheel 401. As Figure 3 shown, the centering mechanism 2 is provided with a centering block 201 that can move in a spreading and closing manner. And as Figure 1As shown, each centering block 201 is arranged outside the lower pressing plate 502. When the present invention works, the rotating body disk 7 is placed on the lower pressing plate 502, and then each centering block 201 in the centering mechanism 2 starts to clamp and squeeze the rotating body disk 7 to achieve centering and positioning. After the positioning is completed, the upper pressing plate 501 descends and cooperates with the lower pressing plate 502 to limit the axial displacement of the rotating body disk 7. Then, the electromagnetic heating element 601 in the electromagnetic heating mechanism 6 moves forward to one side of the rotating body disk 7. Then, the rotating body disk 7 is driven to rotate by the lower pressing plate 502, and the cutting edge is heated by the electromagnetic heating element 601. After heating to the set temperature, the rotating body disk 7 continues to rotate driven by the lower pressing plate 502, and the forging mechanism 4 is driven to move forward by the forging feeding mechanism 3 and the other side of the rotating body disk 7 enters between the upper forging wheel 402 and the lower forging wheel 401. After the cutting edge that has been heated enters the forging mechanism 4, it is continuously forged by the upper forging wheel 402 and the lower forging wheel 401, and the electromagnetic heating element 601 on the other side remains in the heating state, thereby ensuring that the forging temperature of the cutting edge remains unchanged.

[0036] As Figure 2 shown, in this embodiment, the pressing mechanism 5 includes a pressing mounting seat 505, and an upper mounting portion 5051 is provided at the upper end of the pressing mounting seat 505, and a lower mounting portion 5053 is provided at the lower end. A notch 5052 is formed between the upper mounting portion 5051 and the lower mounting portion 5053, and both the upper pressing plate 501 and the lower pressing plate 502 are arranged in the notch 5052. A pressing cylinder 503 (a hydraulic cylinder in this embodiment) is provided on the upper mounting portion 5051, and the upper pressing plate 501 is driven to move up and down by the pressing cylinder 503. A right-angle speed reducer 506 is provided on the lower mounting portion 5053. The power output end on the upper side of the right-angle speed reducer 506 is connected to the lower pressing plate 502, and the power input end at the lower end is connected to a motor 504 arranged on one side of the pressing mounting seat 505. The motor 504 drives the lower pressing plate 502 to rotate by transmitting torque through the right-angle speed reducer 506. Additionally, as Figure 1 shown, the centering mechanism 2 is fixedly installed on the lower mounting portion 5053.

[0037] As Figure 3As shown, in this embodiment, the centering mechanism 2 includes guide shafts 205 on both sides, and a fixed block 206 is provided in the middle of the guide shafts 205 and fixed on the lower mounting portion 5053 of the pressing mounting seat 505. A centering cylinder 202 is provided between the two guide shafts 205, and a cylinder mounting plate 204 is provided at the rear end of the cylinder body of the centering cylinder 202 and fixed on the lower mounting portion 5053. The power shaft end of the centering cylinder 202 is fixedly connected to a driving link plate 207, and each end of the guide shaft 205 passes through the driving link plate 207. Driving rods 208 are provided on both sides of the driving link plate 207. Movable centering blocks 201 are sleeved at both ends of the guide shaft 205, and the driving rod 208 is connected to the adjacent centering block 201. A cross-link assembly 203 is provided outside the guide shaft 205, and the middle of the cross-link assembly 203 is installed on the corresponding fixed block 206 through an intermediate hinge shaft 2032. Both ends of the cross-link assembly 203 are respectively connected to the centering blocks 201 on the corresponding side through end hinge shafts 2031.

[0038] When the centering mechanism 2 works, the centering cylinder 202 drives the driving link plate 207 to move. The driving link plate 207 drives the adjacent centering block 201 to move through the driving rod 208. At the same time, this centering block 201 drives the centering block 201 on the other side to move synchronously through the cross-link assembly 203. And due to the opening and closing movement of each group of cross rods in the cross-link assembly 203, this can enable the centering block 201 on the other side to achieve synchronous movement in the opposite direction. For example, when the driving rod 208 drives the centering block 201 connected to it to approach the fixed block 206, each group of cross rods in the cross-link assembly 203 are in an opening action, thereby driving the centering block 201 on the other side to also approach the fixed block 206 synchronously, and then realizing the opening and closing of each centering block 201. Additionally, since the opening and closing angles of each group of cross rods are the same, this can facilitate the analysis and calculation by the equipment control system and precisely control the displacement of each centering block 201, thereby avoiding the situation that the centering block 201 has too large a displacement and generates a large clamping force to damage the workpiece, or the displacement is too small and the centering and positioning effect is not achieved. At the same time, as Figure 1 shown, the guide shafts 205 and the cross-link assembly 203 on both sides of the centering mechanism 2 can be respectively arranged in the gaps between the electromagnetic heating mechanism 6 and the pressing mounting seat 505 and between the forging feeding mechanism 3 and the pressing mounting seat 505, so that the overall structure of the present invention is compact and does not occupy too much installation space.

[0039] As Figure 4 shown, in this embodiment, the electromagnetic heating mechanism 6 includes a heating support 603 and a heating moving module 602, wherein the heating support 603 is designed in an inverted concave shape, and as Figures 1-2As shown, the motor 504 in the pressing mechanism 5 can be arranged in the heating support 603, so as to further ensure the overall compact structure of the present invention. The heating moving module 602 is arranged on the heating support 603, and the electromagnetic heating element 601 is driven to move by the heating moving module 602. The heating moving module 602 can select a suitable device according to actual needs. For example, in this embodiment, the heating moving module 602 includes a heating driving motor and a heating driving lead screw. The heating driving lead screw is driven to rotate by the heating driving motor, and a heating driving nut is sleeved on the heating driving lead screw and connected to the heating moving seat 6021. The present invention can accurately control the displacement of the heating moving seat 6021 through the above motor lead screw structure, and further accurately control the displacement of the electromagnetic heating element 601.

[0040] One of the main purposes of the present invention using electromagnetic induction heating is to reduce the pressure required for workpiece deformation, so that the blank is pressed and undergoes continuous point-by-point deformation. As Figure 4 shown, in this embodiment, the electromagnetic heating element 601 includes two arc-shaped heating parts 6011 arranged up and down and having an arc matching the outer circumference of the rotary body disk 7. A heating slot 6012 is formed between the two arc-shaped heating parts 6011. When the electromagnetic heating mechanism 6 works, the cutting edge of the rotary body disk 7 is inserted into the heating slot 6012. In addition, coil side plates 6014 are provided on both sides of the electromagnetic heating element 601, and side plate slots 6016 are provided on the coil side plates 6014 and are connected to the heating slot 6012. A coil lead connecting plate 6015 is provided on any one of the coil side plates 6014 and is connected to the electromagnetic heating controller through a circuit. Through the structural design of the electromagnetic heating element 601 of the present invention, it can ensure that all-round uniform heating is achieved at the relevant positions of the cutting edge, there will be no heating dead angle, the thermal efficiency is high, and this kind of coil heating structure has a very fast thermal start. The average preheating time is greatly shortened compared with the conventional heating method, improving the work efficiency. At the same time, its temperature control is more accurate, which can meet the heating temperature control requirements of the relevant positions of the cutting edge with relatively thin thickness, and further ensure the subsequent forging quality. In addition, side plate slots 6016 are provided on the coil side plates 6014 on both sides of the electromagnetic heating element 601 for the cutting edge of the rotary body disk 7 to pass through, which will not affect the rotation of the rotary body disk 7 driven by the lower pressing plate 502.

[0041] As Figure 4 shown, in this embodiment, an installation plate 6013 is provided at the rear side of the middle of the electromagnetic heating element 601, and the installation plate 6013 is installed on the heating moving seat 6021. In this way, the present invention can replace the appropriate electromagnetic heating element 601 according to the specifications of the rotary body disk 7 to be processed.

[0042] The electromagnetic heating principle of the electromagnetic heating element 601 is a well-known technology in the art. For example, reference can be made to the electromagnetic heating blocks in patents such as CN202981589U and CN105645309B. In this embodiment, the electromagnetic heating controller connected to the electromagnetic heating element 601 rectifies the alternating current of 220V, 50 / 60HZ into direct current, and then converts the direct current into high-frequency high-voltage electricity with a frequency of 20 - 40KHZ and applies it to the electromagnetic heating element 601 to achieve electromagnetic heating.

[0043] As Figure 5 shown, in this embodiment, the forging mechanism 4 includes a forging mounting base 404. Inside the forging mounting base 404, there are a lifting slider 403 and a fixed block. Among them, the upper forging wheel 402 is arranged on the lifting slider 403, the lower forging wheel 401 is arranged on the fixed block, a forging cylinder 405 (a hydraulic cylinder in this embodiment) is arranged at the upper end of the forging mounting base 404, and the lifting slider 403 is driven to lift by the forging cylinder 405.

[0044] As Figure 6 shown, in this embodiment, the forging feeding mechanism 3 includes a forging moving base 302, a forging feeding motor 301, and a forging feeding lead screw. The forging feeding lead screw is driven to rotate by the forging feeding motor 301. A feeding nut is sleeved on the forging feeding lead screw and connected to the forging moving base 302. The lower end of the forging mounting base 404 of the forging mechanism 4 is fixedly arranged on the forging moving base 302. Through the above motor lead screw structure design, the present invention can accurately control the feeding displacement of the forging mechanism 4.

[0045] As Figure 1 shown, in this embodiment, the pressing mechanism 5, the electromagnetic heating mechanism 6, and the forging feeding mechanism 3 are all arranged on a base 1 to facilitate the overall transfer of the present invention. Among them, as Figure 6 shown, the forging feeding mechanism 3 includes a feeding base 304, and the forging feeding motor 301 and the forging feeding lead screw are both arranged on the feeding base 304. Both sides of the forging moving base 302 are slidably connected to the feeding base 304 through a slide rail-slider assembly 303. The feeding base 304, together with the pressing mounting base 505 in the pressing mechanism 5 and the heating support 603 in the electromagnetic heating mechanism 6, are all arranged on the base 1.

[0046] The working principle of the present invention is as follows:

[0047] When the present invention works, it includes the following steps:

[0048] Step 1: The rotary disk 7 is placed on the lower pressing disk 502 of the pressing mechanism 5;

[0049] Step 2: Start closing each centering block 201 in the centering mechanism 2 to clamp and center the rotating body disk 7. After the positioning is completed, each centering block 201 retracts to its original position;

[0050] Step 3: The upper pressing plate 501 of the pressing mechanism 5 descends by a set height and cooperates with the lower pressing plate 502 to fix the rotating body disk 7;

[0051] Step 4: The electromagnetic heating element 601 in the electromagnetic heating mechanism 6 moves forward to one side of the rotating body disk 7,

[0052] Step 5: The rotating body disk 7 is driven to rotate by the lower pressing plate 502, and the cutting edge is heated by the electromagnetic heating element 601;

[0053] Among them, the rotating body disk 7 is driven to rotate by the lower pressing plate 502 for a set number of turns (one turn in this embodiment), so that the entire circumference of the rotating body disk 7 is heated;

[0054] Step 6: After the rotating body disk 7 is heated to the set temperature, the lower pressing plate 502 drives the rotating body disk 7 to continue rotating, while the forging mechanism 4 is driven to move forward by the forging feeding mechanism 3 and the other side of the rotating body disk 7 enters between the upper forging wheel 402 and the lower forging wheel 401. The cutting edge that has been heated enters the forging mechanism 4. At the same time, the upper forging wheel 402 in the forging mechanism 4 starts to lift and cooperate with the lower forging wheel 401 to continuously forge the heated cutting edge, while the electromagnetic heating element 601 on the other side remains in the heating state, thus ensuring that the forging temperature of the cutting edge remains unchanged.

[0055] As Figures 7-10 shown, after the present invention finishes processing the rotating body disk 7, the hardness of its cutting edge is further improved compared to the hardness of other parts of the rotating body disk 7, and it will not affect the performance of other parts. Among them Figure 8 shown is the hardness comparison schematic diagram of the body, heating area, and cutting edge of the rotating body disk 7 after being processed in an application example of the present invention. Compared with the body, the hardness of the cutting edge is further increased by 2HRC. Figure 9 shown is the metallographic structure schematic diagram of each part before the processing of this application example. Figure 10 is the metallographic structure schematic diagram of each part before the processing of this application example. Through Figures 7-10 shown, it can be seen that when the conventional performance of the rotating body disk 7 reaches the limit in forging, the present invention can achieve further breakthroughs in the performance of the cutting edge, thereby further improving the wear resistance and service life of the workpiece.
