Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, in particular to a stamping die device for box processing. Background Art

[0002] The existing box body is in direct contact with the stamping block during stamping, lacks buffering, and causes certain damage to the stamping equipment. In addition, the existing stamping equipment is inconvenient to demould, and professional demoulding equipment is required for demoulding, which affects work efficiency. At the same time, when the demoulding is completed, the staff needs to manually remove the box body, which increases the labor intensity of the staff.

[0003] To this end, the Chinese patent with publication number "CN214919861U" announced "A stamping equipment for automobile parts production and processing", whose main structure includes a box body, a cylinder fixedly connected to the center of the top of the box body, and the bottom end of the cylinder passes through the center of the top of the box body and extends to the inner cavity of the box body, the bottom end of the cylinder is fixedly connected to a connecting plate, and the connecting plate is located in the inner cavity of the box body, and the bottom of the connecting plate is fixedly connected to a first connecting block near the left and right sides, and a sliding groove is provided on one side of the first connecting block near the center of the connecting plate. Through the mutual cooperation between structures such as rocker arms, threaded rods, molds, and clamps, the automobile parts can be fixed and clamped to prevent the automobile parts from deviating during stamping. Through the mutual cooperation between structures such as cylinders, connecting plates, second movable plates, stamping blocks, springs, etc., the stamping blocks can be buffered to prevent the stamping equipment from being damaged.

[0004] It is obvious that the above-mentioned stamping equipment for the production and processing of automobile parts utilizes the mutual cooperation between the cylinder, connecting plate, second movable plate, stamping block, spring and other structures to achieve buffering, and utilizes the electric telescopic rod to eject the automobile parts to achieve rapid demoulding. However, there is no effective linkage measure between the buffering components and the demoulding components, resulting in a relatively low effective utilization rate of the stamping kinetic energy. In addition, during demoulding, it is necessary to rely on electric energy to eject the formed box, resulting in increased manufacturing and use costs. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1 and Figure 2 A stamping die equipment for box processing includes a bottom fixed base 1 that can be fixedly mounted on a work surface, a top fixed base plate 2 located directly above the bottom fixed base 1, a hydraulic telescopic cylinder 3 fixedly mounted on the top of the top fixed base plate 2, an upper box mold 4 that can move longitudinally with the telescopic rod of the hydraulic telescopic cylinder 3, a lower box mold 5 located directly below the upper box mold 4, and a No. 1 rod through-hole 6 arranged inside the lower box mold 5. The components for manufacturing the box are placed on the lower box mold 5, and then the hydraulic telescopic cylinder 3 is started. The telescopic rod of the hydraulic telescopic cylinder 3 will drive the upper box mold 4 to move downward and cooperate with the lower box mold 5, so that the components are stamped and shaped into a box structure.

[0029] In order to achieve buffer support and improve the effective utilization of punching kinetic energy, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , it is necessary to set up two buffer-type support mechanisms 7, which are internally provided with a longitudinal support rod 71 fixedly installed between the bottom fixed base 1 and the top fixed base plate 2 and having a hollow interior, an inner movable plate 712 placed inside the longitudinal support rod 71 and capable of moving downward with the lower box mold 5, and a No. 1 piston plate 717 that moves with the inner movable plate 712 and can change the air pressure in the space below itself.

At this time, the No. 1 coil spring 716 will play an effective buffering function. At the same time, the movement of the No. 1 piston plate 717 will cause the gas holding space below it to decrease and the pressure to increase, thereby increasing the gas pressure in this area and transmitting it to the No. 1 gas flow hole 86 through the ventilation pipe 10, thereby converting the stamping kinetic energy into kinetic energy formed by gas compression, thereby achieving buffer support and improving the effective utilization rate of the stamping kinetic energy.

[0030] For the specific structure of the buffer support mechanism 7, please refer to Figure 3 and Figure 4, including a lower sliding ring 714 and an upper sliding ring 718, the bottom end of the longitudinal support rod 71 is fixedly mounted on the upper surface of the bottom fixed base 1 through the No. 1 connecting plate 72, and the top end of the longitudinal support rod 71 is fixedly mounted on the lower surface of the top fixed base plate 2 through the No. 2 connecting plate 73. A gas compression chamber 74 is provided inside the longitudinal support rod 71, and a No. 1 longitudinal component active chamber 711 is provided just above the gas compression chamber 74. The gas compression chamber 74 and the No. 1 longitudinal component active chamber 711 are connected through the No. 2 rod body through-hole 79.

The outer periphery of the rod body of the longitudinal telescopic rod 715 is sheathed with a No. 1 coil spring 716 that generates an upward elastic force on the inner movable plate 712. Both sides of the inner movable plate 712 are respectively provided with a limit slide 713 that can slide longitudinally along the longitudinal slide groove 710. The rod body of the longitudinal support rod 71 is sheathed with a lower sliding ring 714 that can move longitudinally thereof, and the circumferential inner wall of the lower sliding ring 714 is fixedly connected to the end of the limit slide 713. The longitudinal support rod 71 is provided with an upper sliding ring 718 on the rod body above the lower sliding ring 714. The bottom of the upper sliding ring 718 is fixedly connected to the lower box mold 5 through a longitudinal connecting rod 719. The air inlet of the gas one-way valve 78 faces the external environment, and the exhaust port faces the gas limiting flow cavity 75. The structural shape of the cross section of the No. 2 rod body through-hole 79 is consistent with the structural shape of the cross section of the longitudinal telescopic rod 715, both of which are polygonal structures, and the structural dimensions of the cross section of the No. 2 rod body through-hole 79 match the structural dimensions of the cross section of the longitudinal telescopic rod 715.

[0031] In order to use the kinetic energy of gas compression to eject the formed box, please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6, it is necessary to set up a pneumatic ejection mechanism 8, which is provided with a No. 1 longitudinal hollow shell 81 fixedly installed at the bottom of the lower box mold 5 and with a hollow interior, a No. 2 piston body 88 that can move upward under the gas pressure from the longitudinal support rod 71, and a longitudinal ejector rod 810 that moves with the No. 2 piston body 88 and extends into the lower box mold 5. Part of the gas entering the No. 1 gas flow hole 86 will be pre-stored in the No. 1 gas flow hole 86 to form a high-pressure area. When the upper box mold 4 is reset upward, under the action of the high-pressure gas, the No. 2 piston body 88 will move upward, so that the top end of the longitudinal ejector rod 810 will extend into the lower box mold 5 and eject the box inside the lower box mold 5, thereby utilizing the kinetic energy of gas compression to perform the ejection function on the formed box.

[0032] For the specific structure of the pneumatic ejection mechanism 8, please refer to Figure 5 and Figure 6 , including a No. 2 coil spring 89, the No. 1 longitudinal hollow shell 81 is fixedly installed on the bottom of the lower box mold 5 through a No. 3 connecting plate 82, and a No. 4 connecting plate 83 is provided at the bottom of the No. 1 longitudinal hollow shell 81. A gas pre-storage chamber 84 is provided inside the No. 1 longitudinal hollow shell 81. The top of the gas pre-storage chamber 84 is connected to the No. 1 rod body through-hole 85 and the No. 1 rod body through-hole 6. The bottom end of the gas pre-storage chamber 84 is connected to the environment below it through the No. 1 gas flow hole 86. The two symmetrical sides of the gas pre-storage chamber 84 are connected to the side environment through the No. 2 docking channel 87. The second docking channel 87 is connected with the first docking channel 76 through the ventilation pipe 10. The interior of the gas pre-storage chamber 84 is provided with a No. 2 piston body 88 that can move along its longitudinal direction. The top end of the No. 2 piston body 88 is fixedly installed with a longitudinal push rod 810 that passes through the No. 3 rod body through-hole 85 and extends into the No. 1 rod body through-hole 6. The outer periphery of the rod body of the longitudinal push rod 810 is covered with a No. 2 coil spring 89 that generates downward elastic pressure on the No. 2 piston body 88. The axial movable range of the longitudinal push rod 810 is sufficient to enable the molding box located in the lower box mold 5 to be ejected.

[0033] In order to discharge the excess gas to the outside while retaining some gas as the gas required for ejection, please refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8, it is necessary to set up a pre-stored gas pressure control mechanism 9, which is provided with a No. 2 longitudinal hollow shell 91 fixedly mounted on the bottom of the No. 4 connecting plate 83 and hollow inside, a movable valve plate 96 located inside the No. 2 longitudinal hollow shell 91 and blocked at the No. 1 rod body perforation 6 port, and a No. 3 coil spring 911 that exerts upward elastic pressure on the movable valve plate 96. When the high-pressure gas entering the No. 1 gas flow hole 86 is greater than the elastic strength of the No. 3 coil spring 911, the movable valve plate 96 will move downward, and the excess gas will be discharged to the external environment through the No. 2 gas flow hole 94, the gas flow groove 97, the movement gap of the movable valve plate 96 and the No. 3 gas flow hole 95, and the air pressure less than the No. 3 coil spring 911 will be pre-stored in the No. 1 gas flow hole 86. When the ejection work is completed, the pull rod 910 is pulled downward. Under the action of the No. 2 coil spring 89, the longitudinal ejector rod 810 can be reset downward, thereby discharging the excess gas outward while retaining part of the gas as the gas required for ejection.

[0034] For the specific structure of the pre-stored gas pressure control mechanism 9, please refer to Figure 7 and Figure 8 , including a No. 2 longitudinal component active chamber 93 arranged inside the No. 2 longitudinal hollow shell 91, the top of the No. 2 longitudinal hollow shell 91 is fixedly connected to the No. 4 connecting plate 83 through the No. 5 connecting plate 92, the top of the No. 2 longitudinal component active chamber 93 is connected to the bottom port of the No. 1 gas flow hole 86 through the No. 2 gas flow hole 94, and the bottom end of the No. 2 longitudinal component active chamber 93 is connected to the environment below it through the No. 3 gas flow hole 95. A movable valve plate 96 that can move longitudinally is placed inside the No. 2 longitudinal component active chamber 93, and a plurality of gas flow grooves 97 for gas flow are provided on the edge of the movable valve plate 96. The upper surface of the movable valve plate 96 is provided with an annular embedded groove with an inner concave structure. 98. An annular sealing gasket 99 is embedded in the annular embedding groove 98. A pull rod 910 that passes through the No. 3 gas flow hole 95 is fixedly installed on the bottom surface of the movable valve plate 96. A No. 3 coil spring 911 that generates upward elastic strength for the movable valve plate 96 is placed on the periphery of the pull rod 910. There is a gap for gas flow between the pull rod 910 and the No. 3 gas flow hole 95. The depth of the annular embedding groove 98 is less than the thickness of the annular sealing gasket 99, and the structural radius of the inner ring of the annular sealing gasket 99 is greater than the structural radius of the No. 2 gas flow hole 94, and the structural radius of the outer ring of the annular sealing gasket 99 is less than the distance between the gas flow groove 97 and the axial center line of the movable valve plate 96.

[0035] When in use, the parts for making the box body are placed on the lower box body mold 5, and then the hydraulic telescopic cylinder 3 is started. The telescopic rod of the hydraulic telescopic cylinder 3 will drive the upper box body mold 4 to move downward and cooperate with the lower box body mold 5 so that the parts are stamped and shaped into a box body structure. When the upper box body mold 4 completes the stamping and shaping of the lower box body mold 5, its residual kinetic energy will cause the lower box body mold 5 to drive the upper sliding ring 718 to move downward, and then the lower sliding ring 714 will drive the inner movable plate 712 to move downward. At this time, the No. 1 coil spring 716 will play an effective buffering role. At the same time, the movement of the No. 1 piston plate 717 will reduce the gas holding space below it and increase the pressure, thereby increasing the gas pressure in this area and transmitting it to the No. 1 gas flow hole 86 through the ventilation pipe 10, entering the No. 1 gas flow When the high-pressure gas inside the movable hole 86 is greater than the elastic strength of the No. 3 coil spring 911, the movable valve plate 96 will move downward, and the excess gas will be discharged to the external environment through the No. 2 gas flow hole 94, the gas flow groove 97, the movement gap of the movable valve plate 96 and the No. 3 gas flow hole 95, and the air pressure less than the No. 3 coil spring 911 will be pre-stored inside the No. 1 gas flow hole 86. When the upper box mold 4 is reset upward, under the action of the high-pressure gas, the No. 2 piston body 88 will move upward, so that the top end of the longitudinal push rod 810 extends into the lower box mold 5 and ejects the box inside the lower box mold 5. When the ejection work is completed, pull the pull rod 910 downward, and under the action of the No. 2 coil spring 89, the longitudinal push rod 810 can be reset downward.
