DETAILED DESCRIPTION

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.

[0018] Please refer to the attached Figure 1 -Attached Fig. 9 The embodiment of the present invention provides a metal gasket forming and manufacturing device for fasteners, including a workbench 1, which is divided into a circulation process area and a loading area. The circulation process area is divided into a stamping area, a cooling area, a tempering area and a unloading area. The stamping area and the loading area are located on the same side. A circulation rotation mechanism is arranged in the circulation process area. There are four lower molds 2 in a circular array in the circulation rotation mechanism. The four lower molds 2 are driven by the circulation rotation mechanism to rotate synchronously along the circulation process area. A crossbeam 3 is arranged above the workbench 1. The crossbeam 3 is fixedly connected to the workbench 1 through a support 4. Three cylinders 5 are fixedly connected to the beam body of the crossbeam 3. The three cylinders 5 are sequentially distributed in the stamping area, the cooling area and the tempering area. Among them, the output ends of the two cylinders 5 located in the stamping area and the tempering area are respectively fixedly connected to the upper mold 6. An electric heating device is arranged in the upper mold 6 for heating the metal gasket. The output end of the cylinder 5 located in the cooling area is fixedly connected to the cooling device 7. The cooling device 7 is used to quench the metal gasket.

[0019] When the metal gasket forming and manufacturing device is in operation, the stamping raw material enters the stamping area from the loading area, and is stamped and formed in the stamping area by the cooperation of the cylinder 5, the lower mold 2 and the upper mold 6 to form a metal gasket of preset specifications, and simultaneously quickly completes induction heating on it, and then, the circulating rotation mechanism drives the lower mold 2 to rotate to the cooling area, and the cooling device 7 is used to cool and quench the heated metal gasket, and the circulating rotation mechanism drives the lower mold 2 to rotate to the tempering area again, and the cylinder 5 and the upper mold 6 in the tempering area are used to temper the quenched metal gasket, and finally, the cooperation of the circulating rotation mechanism and the unloading area is used to realize the unloading of the metal gasket.

[0020] By dividing the workbench 1 into a circulation process area, and cooperating with the upper mold 6, the cooling device 7, and the lower mold 2, the automatic stamping and heat treatment process of the metal gasket is realized, so that the metal gasket completes the heat treatment operation while being stamped and formed, improves its elastic limit, yield strength and fatigue strength, and extends the service life of the metal gasket. At the same time, because the heat treatment process is carried out in the stamping die, the metal gasket is always in a limited state during the heat treatment process, thereby avoiding the deformation of the metal gasket caused by temperature changes.

[0021] The circular rotation mechanism includes a turntable 8, the disk body of the turntable 8 is embedded in and rotatably connected to the upper part of the workbench 1, the upper surface of the turntable 8 is flush with the upper surface of the workbench 1, the bottom wall of the lower mold 2 is embedded in and fixedly connected to the upper inner part of the turntable 8, the upper surface of the lower mold 2 is flush with the upper surface of the turntable 8, a turntable 9 is fixedly connected to the bottom center of the turntable 8, the outer wall of the turntable 9 is fixedly connected to the lower inner part of the workbench 1, and the turntable 9 drives the turntable 8 to rotate periodically 90°.

[0022] The turntable 9 drives the turntable 8 to rotate 90 degrees periodically, thereby achieving the effect of driving the four lower molds 2 to move cyclically, ensuring the continuity and efficiency of the production process.

[0023] The upper mold 6 includes an upper pressing plate 1 601, an upper pressing plate 2 602 and an upper pressing plate 3 603. The upper pressing plate 1 601 is located below the upper pressing plate 2 602, and the upper pressing plate 3 603 is located above the upper pressing plate 2 602. The three are attached to each other and fixedly connected by bolts 604. A stamping column 1 605 is penetrated and fixedly connected in the middle of the upper pressing plate 3 603. The top of the stamping column 1 605 is fixedly connected to the output end of the cylinder 5. The center of the upper pressing plate 2 602 is penetrated by a The stamping column 3 609 is clamped, and a slide groove 608 is provided at the center of the upper pressing plate 1 601. The stamping column 2 607 is slidably connected in the slide groove 608. The center of the stamping column 2 607 is sleeved and slidably connected to the lower part of the stamping column 3 609. The upper pressing plate 2 602 is also provided with a through hole 606. The spring 2 610 is embedded in the through hole 606. The two ends of the spring 2 610 are respectively fixedly connected to the bottom wall of the stamping column 1 605 and the top wall of the stamping column 2 607. A high-frequency induction coil 611 is provided in the upper pressing plate 1 601. When the upper mold 6 cooperates with the lower mold 2 to stamp the metal gasket, the high-frequency induction coil 611 is fed with high-frequency alternating current. At this time, the metal gasket is in the inner circle of the high-frequency induction coil 611 and generates eddy current. The lower mold 2 includes a base 201, a boss 202 is fixedly connected to the center of the upper surface of the base 201, a bottom plate 203 is sleeved and slidably connected to the outer wall of the boss 202, the lower wall of the bottom plate 203 and the upper wall of the base 201 are fixedly connected by a spring 204, a discharge groove 205 that is interconnected is provided at the center of the base 201 and the center of the boss 202, a lower mold groove 206 is provided on the upper surface of the boss 202, the bottom center of the lower mold groove 206 is interconnected with the upper opening of the discharge groove 205, when the bottom plate 203 is not subjected to external force, under the action of the spring 204, the upper surface of the bottom plate 203 is flush with the upper surface of the turntable 8. The cooling device 7 includes a cooling outer cylinder 701, in which a cooling inner cylinder 702 is embedded and fixedly connected. The bottom end of the cooling outer cylinder 701 is connected to the inside of the cooling inner cylinder 702 through an upper spray channel 704. A lower spray channel 703 is provided at the bottom of the cooling inner cylinder 702. When the cylinder 5 pushes the bottom wall of the cooling outer cylinder 701 to collide with the metal gasket, the bottom of the cooling inner cylinder 702 passes through the metal gasket. At this time, the coolant is injected into the cooling inner cylinder 702 through the cooling pipe, and is sprayed out to the upper and lower surfaces of the metal gasket by the upper spray channel 704 and the lower spray channel 703 respectively.

[0024] In the stamping area, the cylinder 5 drives the upper die 6 to press down, and cooperates with the lower die 2 corresponding to the upper die 6 to complete the stamping of the metal gasket. At the same time, when the stamping is completed, the metal gasket is located in the high-frequency induction coil 611, and the high-frequency induction coil 611 is connected to a high-frequency alternating current. The high-frequency induction coil 611 will generate an alternating magnetic field with the same frequency, so an induced current with the same frequency will be generated in the metal gasket. This current forms a loop in the metal gasket, forming an eddy current. This eddy current can convert electrical energy into thermal energy to heat the metal gasket. The eddy current is unevenly distributed in the metal gasket, with a large surface density and a small core density. The higher the frequency of the current passed into the high-frequency induction coil 611, the thinner the surface layer where the eddy current is concentrated. This phenomenon is called the skin effect. Due to the skin effect, the surface of the metal gasket is quickly heated to the quenching temperature. Then, the circulating rotating mechanism drives the metal gasket to move quickly to the cooling zone. Driven by the cylinder 5, the cooling device 7 makes the bottom wall of the outer cylinder 701 contact the metal gasket, and at the same time, the bottom of the cooling inner cylinder 702 passes through the metal gasket. The coolant is injected into the cooling inner cylinder 702 through the cooling pipe, and is sprayed from the upper nozzle 704 and the lower nozzle 703 to the upper and lower surfaces of the metal gasket, respectively, to cool the metal gasket, and the surface of the metal gasket is hardened.

[0025] Similarly, the metal gasket after cooling and quenching is moved to the tempering zone, where the cylinder 5 drives the upper mold 6 to press down to complete the limitation of the metal gasket, and at the same time, the metal gasket is located in the high-frequency induction coil 611. The high-frequency induction coil 611 is connected to a lower frequency alternating current than the stamping zone, so that the metal gasket is tempered at a low temperature, and the temperature is maintained between 180-200°C to reduce the stress caused by quenching.

[0026] The feeding area is provided with a feeding channel 10 , the bottom wall of the feeding channel 10 is fixedly connected to the upper surface of the workbench 1 , a guide groove 1001 is opened at the bottom center of the feeding channel 10 , and a guide wheel 1002 is arranged above the guide groove 1001 .

[0027] The metal sheet material is inputted from the feeding channel 10 , and under the limitation of the guide groove 1001 and the guide wheel 1002 , it adheres to the upper surface of the workbench 1 and enters the stamping area.

[0028] The unloading area is provided with baffle 1 11 and baffle 2 12, and the bottom walls of the two are fixedly connected to the upper surface of the workbench 1, and the two together constitute a unloading guide channel. The workbench 1 is provided with a unloading port 13, and the unloading port 13 is located in the unloading guide channel, and a material box is arranged below the unloading port 13. The metal gasket moves with the turntable 8, and moves to the unloading port 13 under the guidance of the unloading guide channel, and finally falls into the material box. Baffle three 1101 is fixedly connected to the upper surface of one end of baffle one 11 away from the discharge port 13, and an electric push rod 1106 is fixedly connected to one side of baffle three 1101. The output end of the electric push rod 1106 passes through baffle three 1101 and is fixedly connected to one end of spring three 1105. The other end of spring three 1105 is fixedly connected to a limit plate 1103. The bottom wall of the limit plate 1103 is fixedly connected to a support rod 1102. The support rod 1102 passes through the baffle one 11 and is slidably connected thereto. A roller 1104 is provided at the bottom end of the support rod 1102, and the spring three 1105 is located between baffle one 11 and baffle three 1101.

[0029] When the lower mold 2 moves from the tempering zone to the unloading zone and passes through the roller 1104, the roller 1104 presses down the bottom plate 203 in the lower mold 2 under the action of the spring three 1105, so that the metal gasket is located above the bottom plate 203. During the continuous movement, the roller 1104 touches the metal gasket and makes it fall on the upper surface of the bottom plate 203. At this time, the electric push rod 1106 pulls the roller 1104 up to make the bottom plate 203 rise, so that the metal gasket contacts the baffle plate 2 12, moves with the turntable 8 and the guide limit of the baffle plate 2 12, and finally moves to the unloading port 13 and falls into the material box, thereby realizing the unloading of the metal gasket.

[0030] The baffle plate 1 11, baffle plate 2 12 and related electric push rod 1106, spring 3 1105, limit plate 1103 and other components in the unloading area work together to realize automatic and accurate unloading of metal gaskets.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
