Description

Technical Field

[0001] The invention relates to the technical field of gear forging equipment, and in particular to a spiral bevel gear forging device and a use method thereof. Background Art

[0002] In the past, spiral bevel gears were mainly formed by mechanical cutting. However, this processing method wastes a lot of materials and requires complicated processes and lengthy processing time, which is inefficient. The metal fibers are cut and discontinuous during the cutting process, so the finished product has a low structural strength. Generally, the industry uses forging to perform pressure forming. However, since spiral bevel gears have a spiral tooth shape with a negative draft angle, they cannot be directly demolded during demolding, so the spiral tooth shape needs to be cut with a tool, resulting in the disadvantages of the aforementioned cutting process.

[0003] At present, there are two main forging methods that can be directly demolded. One is to rotate the punch and push the processed spiral bevel gear to make it rotate along the tooth groove in the die to demold. However, this method requires the installation of transmission components such as gears on the punch, and also requires the coordination of components such as motors, racks or chains. The configuration is complicated. In actual application, in order to ensure the rapid molding of gears, high-temperature softened metal is often used for stamping, resulting in too large a contact surface between the finished product and the die. The use of the punch will cause slight deformation of the contact surface, affecting the accuracy of the gear. In view of the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a spiral bevel gear forging device, comprising a bracket, a hydraulic rod is fixedly connected to the inner wall of the bracket, and the other end of the hydraulic rod is fixedly connected to an upper die;

[0005] The pressure mechanism includes a spiral fan gear, a pneumatic cylinder for holding the spiral fan gear, a lower mold, an ejection rack, and a control component for ejecting the spiral fan gear;

[0006] The outer wall of the bracket is fixedly connected to the bottom of the air pressure cylinder, the inner wall of the air pressure cylinder is fixedly connected to the outer wall of the lower mold, and the inner wall of the lower mold is threadedly connected to the outer wall of the ejection rack.

[0007] Preferably, the control component includes an electric telescopic rod fixedly connected to the bottom of the lower mold, the end of the electric telescopic rod away from the lower mold is fixedly connected to the piston plate, an L-shaped through groove is opened on the inner wall of the lower mold, an installation groove is opened on the inner wall of the L-shaped through groove, and a piston rack is slidably connected to the inner wall of the L-shaped through groove.

[0008] Preferably, the control component also includes a hydraulic telescopic rod 1 fixedly connected to the inner wall of the installation groove, a transmission pipe is connected through the outer wall of the hydraulic telescopic rod 1, a hydraulic telescopic rod 2 is fixedly connected to the inner wall of the transmission pipe, the other end of the hydraulic telescopic rod 2 is fixedly connected to the pushing frame, the end of the L-shaped through groove away from the pushing frame is fixedly connected to the fixed frame, a blocking slider is slidably connected to the inner wall of the fixed frame, the outer wall of the blocking slider is fixedly connected to the outer wall of the pushing frame, a spring 5 is fixedly connected to the inner wall of the piston frame, and the end of the spring 5 away from the piston frame is fixedly connected to the inner wall of the L-shaped through groove. Before use, the bracket is installed in the desired position, and then the spiral fan gear inside the lower mold is die-casted through the hydraulic rod and the upper mold to complete the basic die-casting of the equipment. Process, and when the spiral fan gear needs to be demoulded, the power of the electric telescopic rod is turned on, and the electric telescopic rod drives the piston plate to move along the inner wall of the air pressure cylinder toward the lower mold, so that the inside of the air pressure cylinder changes from normal air pressure to high pressure, and the high pressure generates an outward thrust. At this time, the high pressure inside the air pressure cylinder will enter the L-shaped through groove, so that the piston frame moves along the inner wall of the L-shaped through groove toward the installation groove. At this time, the piston frame will compress the hydraulic telescopic rod 1, so that the liquid inside the hydraulic telescopic rod 1 is transmitted to the hydraulic telescopic rod 2 through the transmission pipe, so that the hydraulic telescopic rod 2 is extended, and the extended hydraulic telescopic rod 2 drives the blocking slider to slide downward along the inner wall of the fixed frame through the pushing frame, so that a gap is formed between the blocking slider and the fixed frame.

[0009] Preferably, one end of the transmission tube away from the hydraulic telescopic rod one is through-connected with the outer wall of the hydraulic telescopic rod two, one end of the hydraulic telescopic rod one away from the mounting groove is fixedly connected to the side wall of the piston rack, one end of the L-shaped through groove away from the ejection rack is located on the inner wall of the groove of the lower mold, the outer wall of the piston plate is slidably connected to the inner wall of the air pressure cylinder, and an adjusting component is fixedly connected to the bottom of the lower mold. When the piston rack moves to the corner position of the L-shaped through groove, the high-pressure gas on the left side of the piston rack will act on the gap between the spiral fan gear and the lower mold through the gap between the fixed frame and the blocking slider. By applying the above components, the adhesion area between the spiral fan gear and the lower mold is reduced, and the resistance encountered by the equipment during demolding is reduced.

[0010] Preferably, the adjusting assembly includes a plurality of support frames fixedly connected to the inner wall of the lower mold. A sliding shell is slidably connected to the inner walls of the plurality of support frames. A sliding rod is fixedly connected to the inner wall of the sliding shell. By utilizing the characteristic that the above-mentioned high-pressure gas is ejected outward through the L-shaped through groove, an adjusting assembly is provided inside the device. When the high-pressure gas inside the air pressure cylinder acts on the gap between the spiral fan gear and the lower mold, if the externally ejected high-pressure gas breaks through the external adhesion and successfully discharges into the outside at this time, then the high-pressure gas will be discharged outward through the gap between the sliding shell and the L-shaped through groove. At the same time, the high flow rate of the gas will drive the sliding shell to move in the direction of the L-shaped through groove, so that the sliding shell blocks the air inlet of the L-shaped through groove, making it impossible for the L-shaped through groove to transmit gas again, and avoiding the influence of the high-pressure gas inside the air pressure cylinder on the thrust of other positions after a single L-shaped through groove completes exhaust.

[0011] Preferably, the adjusting assembly further includes a first roller rotatably connected to the end of the sliding rod away from the sliding shell. The outer wall of the sliding rod is slidably connected to the inner wall of the support frame. A first spring is fixedly connected to the inner wall of the sliding shell. The end of the first spring away from the sliding shell is fixedly connected to the outer wall of the support frame. An exhaust assembly is provided on the top of the piston plate. After the L-shaped through groove is blocked, as the pressure on the piston frame decreases, at this time the fifth spring generates a pulling force, causing the piston frame to reset. The piston frame drives the pushing frame and the blocking slider to reset through the first hydraulic expansion rod, ensuring the orderly processing of the device.

[0012] Preferably, the adjusting assembly further includes five first spring telescopic rods fixedly connected to the bottom of the lower mold. The ends of the five first spring telescopic rods away from the lower mold are fixedly connected to a first fixing ring. A second spring telescopic rod is fixedly connected to the inner wall of the first fixing ring. The end of the second spring telescopic rod away from the first fixing ring is fixedly connected to a second fixing ring. An inclined panel is fixedly connected to the top of the second fixing ring.

[0013] Preferably, the exhaust assembly includes three through holes opened at the bottom of the piston plate. An L-shaped bracket is fixedly connected to the top of the piston plate. A sliding blocking rod is slidably connected to the inner wall of the L-shaped bracket. A second spring is fixedly connected to the outer wall of the sliding blocking rod.

[0014] Preferably, the exhaust assembly also includes a push column rotatably connected to the top of the piston plate, a mounting circular plate fixedly connected to the inner wall of the ejection frame, a pressure column slidably connected to the inner wall of the through hole of the mounting circular plate, a spring three fixedly connected to the inner wall of the pressure column, and one end of the spring three away from the pressure column is fixedly connected to the inner wall of the ejection frame. Taking advantage of the characteristic of the sliding shell blocking the L-shaped through groove, an inclined panel is arranged inside the device. As the piston plate continuously moves upward, more sliding shells will block the corresponding L-shaped through grooves, and eventually all the L-shaped through grooves will be blocked, so that the inside of the air cylinder forms a sealed state again, and as the piston plate moves upward, the air pressure in the air cylinder will be converted into a high pressure state again, and as the piston plate continuously moves upward, the plane of the push column will contact the bottom of the fixed ring one, and the upward fixed ring one drives the fixed ring two and the inclined panel to move upward synchronously through the spring telescopic rod two, forcing the inclined surface of the inclined panel to contact the outer wall of the roller one.

[0015] Preferably, the exhaust component also includes a slide groove 1 opened on the inner wall of the lower mold, a slide groove 2 opened on the inner wall of the ejection rack, a sloped slider is slidably connected to the inner wall of the slide groove 2, and a spring 4 is fixedly connected to the side wall of the sloped slider. When starting work, the ejection rack and the top of the lower mold are at the same horizontal position, and at this time the sloped slider will be between the slide groove 1 and the slide groove 2, limiting the upward movement of the ejection rack. As the inclined panel continues to move upward, the roller 1 drives the sliding shell away from the L-shaped through groove. At this time, all the sliding shells are away from the corresponding L-shaped through grooves, so that the high air pressure inside the air pressure cylinder is collectively ejected outward through the L-shaped through groove again, so that there is a gas layer between the groove of the lower mold and the protruding block of the spiral fan gear, thereby reducing the contact surface between the outer wall of the spiral fan gear and the groove of the lower mold and improving the demolding quality of the equipment.

[0016] Preferably, the exhaust assembly also includes a roller 2 rotatably connected to the inner wall of the ejection frame, a roller 3 rotatably connected to the inner wall of the mounting circular plate, an end of the inclined sliding block away from the sliding groove 1 is fixedly connected to a metal chain 1, an end of the metal chain 1 away from the inclined sliding block is fixedly connected to the outer wall of the pressure column, the outer wall of the inclined sliding block is slidably connected to the inner wall of the ejection frame, the bottom of the pressure column is fixedly connected to a metal chain 2, and an end of the metal chain 2 away from the pressure column is fixedly connected to the outer wall of the push column. As the piston plate continues to move upward, the top of the push column will contact the bottom of the pressure column, forcing the pressure column to slide upward along the inner wall of the mounting circular plate, and the upwardly moving pressure column drives the inclined sliding block at the other end to move along the inner wall of the sliding groove 2 toward the direction of the pressure column through the metal chain 1, and at this time the inclined sliding block will lose the restriction on the sliding groove 1, and the pressure column will move upward, and when the ejection frame moves upward, it is affected by the external threaded column, such as Figure 6When the ejector rack moves upward, it will rotate clockwise. The clockwise rotating ejector rack will drive the top and the spiral fan gear to rotate in the same direction. Through the application of the above components, the spiral fan gear can be demolded upward along the groove of the lower mold during demolding, thereby reducing the resistance between the spiral fan gear and the lower mold during demolding.

[0017] A method for using a spiral bevel gear forging device comprises the following steps:

[0018] S1: Install the equipment: Before use, install the bracket at the desired position, and then die-cast the spiral fan gear inside the lower mold through the hydraulic rod and the upper mold;

[0019] S2: Demoulding: When the spiral fan gear needs to be demoulded, the power of the electric telescopic rod is turned on, and the high-pressure gas will act on the gap between the spiral fan gear and the lower mold through the gap between the fixed frame and the blocking slider.

[0020] The present invention has the following beneficial effects:

[0021] (1) In order to solve the problem that the contact surface between the spiral fan gear and the lower mold is too large to be easily demolded, the present invention provides a pressure mechanism and a control component inside the device. Before use, the bracket is installed at the required position, and then the spiral fan gear inside the lower mold is die-casted through the hydraulic rod and the upper mold to complete the basic die-casting process of the device. When the spiral fan gear needs to be demolded, the power of the electric telescopic rod is turned on, and the electric telescopic rod drives the piston plate to move along the inner wall of the air pressure cylinder toward the lower mold, so that the air pressure inside the air pressure cylinder changes from normal air pressure to high pressure, and the high pressure generates an outward thrust. At this time, the high pressure inside the air pressure cylinder will enter the L-shaped through groove, causing the piston frame to move along the inner wall of the L-shaped through groove to the installation position. The piston rack moves in the direction of the slot, at this time, the piston rack will compress the hydraulic telescopic rod 1, so that the liquid inside the hydraulic telescopic rod 1 is transmitted to the hydraulic telescopic rod 2 through the transmission pipe, so that the hydraulic telescopic rod 2 is extended, and the extended hydraulic telescopic rod 2 drives the blocking slider to slide downward along the inner wall of the fixed frame through the pushing frame, so that a gap is formed between the blocking slider and the fixed frame; and when the piston rack moves to the corner position of the L-shaped through groove, at this time, the high-pressure gas on the left side of the piston rack will act on the gap between the spiral fan gear and the lower mold through the gap between the fixed frame and the blocking slider. Through the application of the above components, the adhesion area between the spiral fan gear and the lower mold is reduced, and the resistance encountered by the equipment during demoulding is reduced.

[0022] (2) In order to solve the problem of increasing air pressure inside the air cylinder, the present invention provides an exhaust assembly inside the device, wherein, at the beginning of operation, the ejection rack and the top of the lower mold are at the same horizontal position, and at this time the inclined slider will be between the first slide groove and the second slide groove, limiting the upward movement of the ejection rack. As the piston plate continues to move upward, the top of the push column will contact the bottom of the pressure column, forcing the pressure column to slide upward along the inner wall of the mounting circular plate. The upward-moving pressure column drives the inclined slider at the other end to move along the inner wall of the second slide groove toward the pressure column through the metal chain. At this time, the inclined slider will lose the restriction on the first slide groove, and the pressure column will move upward. When the ejection rack moves upward, it is affected by the external threaded column, such as Figure 6 When the ejector rack moves upward, it will rotate clockwise. The clockwise rotating ejector rack will drive the top and the spiral fan gear to rotate in the same direction. Through the application of the above components, the spiral fan gear can be demolded upward along the groove of the lower mold during demolding, thereby reducing the resistance between the spiral fan gear and the lower mold during demolding.

[0023] (3) The present invention utilizes the characteristic that the high-pressure gas is ejected outward through the L-shaped groove, and an adjusting component is arranged inside the equipment. When the high-pressure gas inside the air cylinder acts on the gap between the spiral fan gear and the lower mold, if the high-pressure gas ejected outward breaks through the external adhesion and is successfully discharged to the outside, the high-pressure gas will be discharged outward through the gap between the sliding shell and the L-shaped groove. At the same time, the high flow rate of the gas will drive the sliding shell to move in the direction of the L-shaped groove, so that the sliding shell blocks the air inlet of the L-shaped groove, so that the L-shaped groove cannot transmit gas again, thereby avoiding that after a single L-shaped groove is exhausted, the thrust of the high-pressure gas inside the air cylinder on other positions is affected; in addition, after the L-shaped groove is blocked, as the pressure on the piston frame decreases, the spring five generates a pulling force to reset the piston frame, and the piston frame drives the push frame and the blocking slider to reset through the hydraulic telescopic rod one, thereby ensuring the orderliness of the equipment processing.

[0024] (4) The present invention utilizes the characteristic of the sliding shell blocking the L-shaped through groove, and an inclined plate is arranged inside the equipment. As the piston plate continues to move upward, more sliding shells will block the corresponding L-shaped through grooves, and finally all the L-shaped through grooves will be blocked, so that the inside of the air pressure cylinder forms a sealed state again. As the piston plate moves upward, the air pressure in the air pressure cylinder will be converted into a high pressure state again. As the piston plate continues to move upward, the plane of the push column will contact the bottom of the fixing ring 1. The moving fixing ring 1 drives the fixing ring 2 and the inclined plate to move upward synchronously through the spring telescopic rod 2, forcing the inclined surface of the inclined plate to contact the outer wall of the roller 1. As the inclined plate continues to move upward, the roller 1 drives the sliding shell away from the L-shaped through groove. At this time, all the sliding shells are away from the corresponding L-shaped through groove, so that the high air pressure inside the air pressure cylinder is collectively ejected outward through the L-shaped through groove again, so that a gas layer exists between the groove of the lower mold and the protruding block of the spiral fan gear, thereby reducing the contact surface between the outer wall of the spiral fan gear and the groove of the lower mold, and improving the demolding quality of the equipment.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] For example, see Figure 1 - Figure 6 The present invention is a spiral bevel gear forging device, comprising a bracket 1, a hydraulic rod 11 is fixedly connected to the inner wall of the bracket 1, and an upper die 12 is fixedly connected to the other end of the hydraulic rod 11;

[0042] The pressure-bearing mechanism 2 includes a spiral fan gear 21, a pneumatic cylinder 22 for holding the spiral fan gear 21, a lower mold 23, an ejection rack 24, and a control component 3 for ejecting the spiral fan gear 21;

[0043] The outer wall of the bracket 1 is fixedly connected to the bottom of the air pressure cylinder 22 , the inner wall of the air pressure cylinder 22 is fixedly connected to the outer wall of the lower mold 23 , and the inner wall of the lower mold 23 is threadedly connected to the outer wall of the ejection frame 24 .

[0044] The control component 3 includes an electric telescopic rod 31 fixedly connected to the bottom of the lower mold 23, and the end of the electric telescopic rod 31 away from the lower mold 23 is fixedly connected to the piston plate 32. An L-shaped through groove 33 is opened on the inner wall of the lower mold 23, and an installation groove 34 is opened on the inner wall of the L-shaped through groove 33. A piston frame 35 is slidably connected to the inner wall of the L-shaped through groove 33.

[0045] The control component 3 also includes a hydraulic telescopic rod 1 36 fixedly connected to the inner wall of the installation groove 34, a transmission pipe 37 is connected to the outer wall of the hydraulic telescopic rod 1 36, a hydraulic telescopic rod 2 38 is fixedly connected to the inner wall of the transmission pipe 37, and the other end of the hydraulic telescopic rod 2 38 is fixedly connected to a pushing frame 39, and the end of the L-shaped through groove 33 away from the pushing frame 24 is fixedly connected to a fixed frame 310, and a blocking slider 311 is slidably connected to the inner wall of the fixed frame 310, and the outer wall of the blocking slider 311 is fixedly connected to the outer wall of the pushing frame 39, and a spring 5 312 is fixedly connected to the inner wall of the piston frame 35, and the end of the spring 5 312 away from the piston frame 35 is fixedly connected to the inner wall of the L-shaped through groove 33. Before use, the bracket 1 is installed in the desired position, and then the spiral fan gear 21 inside the lower mold 23 is die-casted by the hydraulic rod 11 and the upper mold 12 to complete the basic die-casting of the equipment. The process is as follows: when it is necessary to demould the spiral fan gear 21, the power of the electric telescopic rod 31 is turned on, and the electric telescopic rod 31 drives the piston plate 32 to move along the inner wall of the air cylinder 22 toward the lower mold 23, so that the air pressure inside the air cylinder 22 changes from normal air pressure to high pressure, and the high pressure generates an outward thrust. At this time, the high pressure inside the air cylinder 22 will enter the L-shaped through groove 33, so that the piston frame 35 moves along the inner wall of the L-shaped through groove 33 toward the mounting groove 34. At this time, the piston frame 35 will compress the hydraulic telescopic rod 1 36, so that the liquid inside the hydraulic telescopic rod 1 36 is transmitted to the hydraulic telescopic rod 2 38 through the transmission pipe 37, so that the hydraulic telescopic rod 2 38 is extended, and the extended hydraulic telescopic rod 2 38 drives the blocking slider 311 to slide downward along the inner wall of the fixed frame 310 through the pushing frame 39, so that a gap is formed between the blocking slider 311 and the fixed frame 310.

[0046] One end of the transmission pipe 37 away from the hydraulic telescopic rod 1 36 is connected to the outer wall of the hydraulic telescopic rod 2 38, and one end of the hydraulic telescopic rod 1 36 away from the mounting groove 34 is fixedly connected to the side wall of the piston frame 35. The end of the L-shaped through groove 33 away from the ejection frame 24 is located on the inner wall of the groove of the lower mold 23. The outer wall of the piston plate 32 is slidably connected to the inner wall of the air pressure cylinder 22. The bottom of the lower mold 23 is fixedly connected with an adjustment component 4. When the piston frame 35 moves to the corner position of the L-shaped through groove 33, the high-pressure gas on the left side of the piston frame 35 will act on the gap between the spiral fan gear 21 and the lower mold 23 through the gap between the fixed frame 310 and the blocking slider 311. By applying the above components, the adhesion area between the spiral fan gear 21 and the lower mold 23 is reduced, and the resistance encountered when the equipment is demolded is reduced.

[0047] For example 2, please refer to Figure 7 - Fig.12 The present invention is a spiral bevel gear forging device. On the basis of the first embodiment, the adjusting component 4 includes a plurality of support frames 46 fixedly connected to the inner wall of the lower die 23, the inner wall of the plurality of support frames 46 is slidably connected with a sliding shell 47, and the inner wall of the sliding shell 47 is fixedly connected with a sliding rod 48. By utilizing the characteristic that the high-pressure gas is ejected outward through the L-shaped through groove 33, the adjusting component 4 is arranged inside the device. When the high-pressure gas inside the air cylinder 22 acts on the gap between the spiral fan gear 21 and the lower die 23, the adjusting component 4 is adjusted. At this time, if the high-pressure gas sprayed outward breaks through the external adhesion and is successfully discharged to the outside, the high-pressure gas will be discharged outward through the gap between the sliding shell 47 and the L-shaped through groove 33. At the same time, the high flow rate of the gas will drive the sliding shell 47 to move in the direction of the L-shaped through groove 33, so that the sliding shell 47 blocks the air inlet of the L-shaped through groove 33, making the L-shaped through groove 33 unable to transmit gas again, thereby avoiding that after a single L-shaped through groove 33 is exhausted, it affects the thrust of the high-pressure gas in the air pressure cylinder 22 on other positions.

[0048] The adjusting assembly 4 also includes a roller 49 rotatably connected to the end of the sliding rod 48 away from the sliding shell 47. The outer wall of the sliding rod 48 is slidably connected to the inner wall of the support frame 46. A spring 410 is fixedly connected to the inner wall of the sliding shell 47. The end of the spring 410 away from the sliding shell 47 is fixedly connected to the outer wall of the support frame 46. An exhaust assembly 5 is provided on the top of the piston plate 32. After the L-shaped through groove 33 is blocked, as the pressure on the piston frame 35 decreases, the spring 5 312 generates a pulling force to reset the piston frame 35. The piston frame 35 drives the push frame 39 and the blocking slider 311 to reset through the hydraulic telescopic rod 36 to ensure the orderliness of equipment processing.

[0049] The adjustment assembly 4 also includes five spring telescopic rods 41 fixedly connected to the bottom of the lower mold 23, the ends of the five spring telescopic rods 41 away from the lower mold 23 are fixedly connected to a fixing ring 1 42, the inner wall of the fixing ring 1 42 is fixedly connected to a spring telescopic rod 2 43, the end of the spring telescopic rod 2 43 away from the fixing ring 1 42 is fixedly connected to a fixing ring 2 44, and the top of the fixing ring 2 44 is fixedly connected to an inclined panel 45.

[0050] The exhaust assembly 5 includes three through-hole grooves 51 opened at the bottom of the piston plate 32, an L-shaped bracket 52 is fixedly connected to the top of the piston plate 32, a sliding blocking rod 53 is slidably connected to the inner wall of the L-shaped bracket 52, and a spring 2 54 is fixedly connected to the outer wall of the sliding blocking rod 53.

[0051] The exhaust assembly 5 also includes a push column 55 rotatably connected to the top of the piston plate 32, a mounting circular plate 56 is fixedly connected to the inner wall of the ejection frame 24, a pressure column 57 is slidably connected to the inner wall of the through hole of the mounting circular plate 56, a spring three 58 is fixedly connected to the inner wall of the pressure column 57, and one end of the spring three 58 away from the pressure column 57 is fixedly connected to the inner wall of the ejection frame 24. Utilizing the characteristic of the sliding shell 47 blocking the L-shaped through groove 33, an inclined plate 45 is arranged inside the equipment. As the piston plate 32 continuously moves upward, more sliding shells 47 will block the corresponding L-shaped through grooves 33, and finally all the L-shaped through grooves 33 will be blocked, so that the inside of the air cylinder 22 will be sealed again. As the piston plate 32 moves upward, the air pressure in the air cylinder 22 will be converted into a high-pressure state again. As the piston plate 32 continuously moves upward, the plane of the push column 55 will contact the bottom of the fixing ring 42. The upward fixing ring 42 drives the fixing ring 44 and the inclined plate 45 to move upward synchronously through the spring telescopic rod 43, forcing the inclined surface of the inclined plate 45 to contact the outer wall of the roller 49.

[0052] The exhaust component 5 also includes a slide groove 1 59 provided on the inner wall of the lower mold 23, a slide groove 2 510 provided on the inner wall of the ejection frame 24, an inclined slider 511 slidably connected to the inner wall of the slide groove 2 510, and a spring 4 515 fixedly connected to the side wall of the inclined slider 511. When starting work, the ejection frame 24 and the top of the lower mold 23 are at the same horizontal position, and at this time the inclined slider 511 will be between the slide groove 1 59 and the slide groove 2 510, limiting the upward movement of the ejection frame 24. As the inclined plate 45 continues to move upward, the roller 1 49 drives the sliding shell 47 away from the L-shaped through groove 33. At this time, all the sliding shells 47 are away from the corresponding L-shaped through groove 33, so that the high air pressure inside the air pressure cylinder 22 is collectively ejected outward again through the L-shaped through groove 33, so that there is a gas layer between the groove of the lower mold 23 and the protruding block of the spiral fan gear 21, thereby reducing the contact surface between the outer wall of the spiral fan gear 21 and the groove of the lower mold 23, thereby improving the demoulding quality of the equipment.

[0053] The exhaust assembly 5 also includes a roller 2 512 rotatably connected to the inner wall of the push-out frame 24, a roller 3 513 rotatably connected to the inner wall of the mounting circular plate 56, a metal chain 1 514 fixedly connected to the end of the inclined slider 511 away from the slide groove 1 59, an end of the metal chain 1 514 away from the inclined slider 511 is fixedly connected to the outer wall of the pressure column 57, the outer wall of the inclined slider 511 is slidably connected to the inner wall of the push-out frame 24, a metal chain 2 516 is fixedly connected to the bottom of the pressure column 57, and an end of the metal chain 2 516 away from the pressure column 57 is connected to the push The outer wall of the column 55 is fixedly connected. As the piston plate 32 continues to move upward, the top of the push column 55 will contact the bottom of the pressure column 57, forcing the pressure column 57 to slide upward along the inner wall of the mounting circular plate 56. The upward pressure column 57 drives the inclined slider 511 at the other end to move along the inner wall of the slide groove 2 510 toward the pressure column 57 through the metal chain 1 514. At this time, the inclined slider 511 will lose the restriction on the slide groove 1 59. At this time, the pressure column 57 moves upward, and when the push-out frame 24 moves upward, it is affected by the external threaded column, such as Figure 6 When the ejection rack 24 moves upward, it will rotate clockwise. The clockwise rotating ejection rack 24 will drive the top and the spiral fan gear 21 to rotate in the same direction. Through the application of the above components, the spiral fan gear 21 can be demolded upward along the groove of the lower mold 23 during demolding, thereby reducing the resistance between the spiral fan gear 21 and the lower mold 23 during demolding.

[0054] The method for using the spiral bevel gear forging device comprises the following steps:

[0055] S1: Installing the equipment: Before use, the bracket 1 is installed at the desired position, and then the spiral sector gear 21 inside the lower mold 23 is die-casted by the hydraulic rod 11 and the upper mold 12;

[0056] S2: Demolding: When the spiral fan gear 21 needs to be demolded, the power of the electric telescopic rod 31 is turned on, and the high-pressure gas will act on the gap between the spiral fan gear 21 and the lower mold 23 through the gap between the fixing frame 310 and the blocking slider 311.

[0057] A specific application of this embodiment is as follows: before use, the bracket 1 is installed at the desired position, and then the spiral fan gear 21 inside the lower mold 23 is die-casted by the hydraulic rod 11 and the upper mold 12 to complete the basic die-casting process of the equipment. When the spiral fan gear 21 needs to be demolded, the power of the electric telescopic rod 31 is turned on, and the electric telescopic rod 31 drives the piston plate 32 to move along the inner wall of the air cylinder 22 toward the lower mold 23, so that the air pressure inside the air cylinder 22 changes from normal air pressure to high pressure, and the high pressure generates an outward thrust. At this time, the high pressure inside the air cylinder 22 will enter the L-shaped through groove 33, so that the piston frame 35 moves along the inner wall of the L-shaped through groove 33 toward the direction of the installation groove 34. At this time, the piston frame 35 will compress the hydraulic telescopic rod 36 , so that the liquid inside the hydraulic telescopic rod 1 36 is transmitted to the hydraulic telescopic rod 2 38 through the transmission pipe 37, so that the hydraulic telescopic rod 2 38 is extended, and the extended hydraulic telescopic rod 2 38 drives the blocking slider 311 to slide downward along the inner wall of the fixed frame 310 through the pushing frame 39, so that a gap is formed between the blocking slider 311 and the fixed frame 310; and when the piston frame 35 moves to the corner position of the L-shaped through groove 33, the high-pressure gas on the left side of the piston frame 35 will act on the gap between the spiral fan gear 21 and the lower mold 23 through the gap between the fixed frame 310 and the blocking slider 311. Through the application of the above components, the adhesion area between the spiral fan gear 21 and the lower mold 23 is reduced, and the resistance encountered by the equipment during demolding is reduced.

[0058] In order to solve the problem of increasing air pressure inside the air cylinder 22, an exhaust assembly 5 is provided inside the equipment, wherein, at the beginning of operation, the ejection rack 24 and the top of the lower mold 23 are at the same horizontal position, and at this time, the inclined slider 511 will be between the slide groove 1 59 and the slide groove 2 510, limiting the upward movement of the ejection rack 24, and as the piston plate 32 continues to move upward, at this time, the top of the push column 55 will contact the bottom of the pressure column 57, forcing the pressure column 57 to slide upward along the inner wall of the mounting circular plate 56, and the upward-moving pressure column 57 drives the inclined slider 511 at the other end to move along the inner wall of the slide groove 2 510 toward the pressure column 57 through the metal chain 1 514, and at this time, the inclined slider 511 will lose the restriction on the slide groove 1 59, and the pressure column 57 will move upward, and when the ejection rack 24 moves upward, it is affected by the external threaded column, such as Figure 6 When the ejection rack 24 moves upward, it will rotate clockwise. The clockwise rotating ejection rack 24 will drive the top and the spiral fan gear 21 to rotate in the same direction. Through the application of the above components, the spiral fan gear 21 can be demolded upward along the groove of the lower mold 23 during demolding, thereby reducing the resistance between the spiral fan gear 21 and the lower mold 23 during demolding.

[0059] Taking advantage of the above-mentioned feature that the high-pressure gas is ejected outward through the L-shaped groove 33, an adjusting component 4 is arranged inside the equipment. When the high-pressure gas inside the air cylinder 22 acts on the gap between the spiral fan gear 21 and the lower mold 23, if the high-pressure gas ejected outward at this time breaks through the adhesion of the outside and is successfully discharged to the outside, the high-pressure gas will be discharged outward through the gap between the sliding shell 47 and the L-shaped groove 33. At the same time, the high flow rate of the gas will drive the sliding shell 47 to move in the direction of the L-shaped groove 33, so that the sliding shell 47 seals The air inlet of the L-shaped through groove 33 is blocked so that the L-shaped through groove 33 cannot transmit gas again, thereby preventing the high-pressure gas in the air cylinder 22 from affecting the thrust of other positions after the single L-shaped through groove 33 is exhausted. In addition, after the L-shaped through groove 33 is blocked, as the pressure on the piston frame 35 decreases, the spring five 312 generates a pulling force to reset the piston frame 35. The piston frame 35 drives the push frame 39 and the blocking slide block 311 to reset through the hydraulic telescopic rod one 36, thereby ensuring the orderliness of equipment processing.

[0060] By utilizing the characteristic of the sliding shell 47 blocking the L-shaped through groove 33, an inclined plate 45 is provided inside the device. As the piston plate 32 continuously moves upward, more sliding shells 47 will block the corresponding L-shaped through grooves 33, and finally all the L-shaped through grooves 33 will be blocked, so that the inside of the air cylinder 22 forms a sealed state again. As the piston plate 32 moves upward, the air pressure in the air cylinder 22 will be converted into a high pressure state again. As the piston plate 32 continuously moves upward, the plane of the push column 55 will contact the bottom of the fixing ring 1 42, and the fixing ring 1 42 that moves upward will be pushed through the spring telescopic rod 2 43. The fixed ring 24 and the inclined plate 45 are driven to move upward synchronously, forcing the inclined surface of the inclined plate 45 to contact the outer wall of the roller 1 49. As the inclined plate 45 continues to move upward, the roller 1 49 drives the sliding shell 47 away from the L-shaped through groove 33. At this time, all the sliding shells 47 are away from the corresponding L-shaped through groove 33, so that the high air pressure inside the air pressure cylinder 22 is collectively ejected outward through the L-shaped through groove 33 again, so that a gas layer exists between the groove of the lower mold 23 and the protruding block of the spiral fan gear 21, thereby reducing the contact surface between the outer wall of the spiral fan gear 21 and the groove of the lower mold 23, and improving the demolding quality of the equipment.
