Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically a stamping device for the production of lighting fixtures. Background Technology

[0002] Stamping equipment used in the production and processing of lighting fixtures uses stamping pressure to process metal materials into specific shapes and sizes. This type of equipment typically includes punch presses, dies, etc., and can efficiently and accurately complete the stamping and forming of lighting fixture parts, ensuring product quality and consistency. It is an indispensable and important tool in the production of lamp housings.

[0003] For example, a Chinese patent with application number 202410756853.1 discloses a stamping equipment for manufacturing lighting fixtures, including: a support device; a frame, the bottom of which is fixedly connected to the top of the support device.

[0004] A Chinese patent with authorization announcement number CN221869877U discloses a stamping equipment for manufacturing and processing lighting fixtures, including a processing table, a horizontal plate fixedly connected to the bottom end of the processing table, a lower mold fixedly connected to the top end of the processing table, a rectangular groove opened inside the processing table and between the lower molds, and a first electric telescopic rod fixedly connected to both sides of the top end of the horizontal plate.

[0005] The technical solutions in the aforementioned patent documents still have the following defects in actual operation: In the prior art, the stamping production of lamp parts is basically carried out by single-station stamping production. However, the production efficiency of single-station die stamping in the production of lamp parts is limited, and the stamping equipment is relatively large. If a large number of lamp parts are required, adding stamping equipment to improve production efficiency will not only increase equipment costs, but also require a sufficient production workshop, which is quite limiting. The metal materials used for stamping are generally coated with protective oil to protect the metal materials and equipment molds. However, after the metal materials are loaded, the protective oil applied to them is easily wiped off, which will increase the risk of wear on the inner cavity of the equipment mold by the metal materials. Summary of the Invention

[0006] To overcome the aforementioned deficiencies of the prior art, this invention provides a stamping device for the production of lighting fixtures. By adding stamping dies to existing stamping equipment, a dual-station system replaces the existing single-station system, enabling rapid production of lighting fixture parts. This avoids the need for additional stamping equipment, reducing equipment costs while improving production efficiency. Furthermore, it eliminates the need to adjust the scale of the production workshop and configure a corresponding feeding mechanism, thus meeting the requirements for efficient dual-station production of lighting fixture parts. The feeding mechanism can also recoat the metal material with protective oil, thereby reducing wear on the inner cavity of the die equipment and ensuring its service life, thus solving the problems mentioned in the background art.

The oiling sleeve is rotatably connected in the annular groove for absorbing the protective oil.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. By adding stamping dies to existing stamping equipment and configuring corresponding feeding mechanisms, a dual-station system can replace the existing single-station system, enabling rapid production of lighting parts. This avoids the need to add stamping equipment to meet the demand for increased output, thereby reducing equipment costs while improving production efficiency. Furthermore, it eliminates the need to adjust the scale of the production workshop, facilitating the optimization and improvement of existing equipment and workshops.

[0029] 2. The drive components in the feeding mechanism switch synchronously with the operation of the stamping equipment, thereby enabling the feeding of metal materials at two stations. The feeding mechanism is equipped with an oiling component, which applies protective oil to the metal materials that have been rubbed during the feeding process. This ensures the uniformity of the protective oil coating on the metal materials when they enter the stamping die, thereby reducing the wear of the metal materials on the inner cavity of the die equipment, ensuring its service life, reducing the risk of surface damage to the stamping structure in the stamping die, and improving the surface quality of the lighting parts.

[0030] 3. When the drive component is running after switching, it can not only drive the feeding component to feed the metal material, but also synchronously drive the reciprocating movement of the wiping component. Through the movement of the wiping component, the surface of the feeding roller in the feeding component that contacts the metal material is wiped, reducing the protective oil adhering to it and preventing slippage when it comes into contact with the metal material in subsequent movements. This ensures the amount of metal material fed and avoids the occurrence of defective products due to the limited feeding of metal material during the stamping production of lamp parts.

[0031] 4. When the power unit in the stamping equipment drives the force application mechanism to rise and fall, the two stamping dies on the worktable are adjusted to the opposite state, thereby ensuring the continuity of stamping production of lamp parts. Attached Figure Description

[0046] Please see Figures 1-2 In this embodiment of the invention, a stamping device for producing lighting fixtures includes a stamping equipment 1000 and an external control cabinet body. The stamping equipment 1000 includes an equipment frame 1001 and a power unit 1002 disposed on the equipment frame 1001. A loading plate 1003 is installed at the output end of the power unit 1002.

[0047] The control cabinet body is pre-programmed, and then the power unit 1002 in the stamping equipment 1000 is operated under the control of the program, thereby driving the lifting and lowering of the loading plate 1003.

[0048] A workbench 2 located on the equipment frame 1001 is provided directly below the loading plate 1003, and a processing component for stamping and forming lamp parts is provided between the workbench 2 and the loading plate 1003.

[0049] Workbench 2 uses existing technology, which can assemble traditional stamping structures and load processing structures, reducing the cost of equipment optimization.

[0050] Please see Figures 1-4In this embodiment of the invention, the processing components include a processing table 3, a stamping die 4, a force-bearing wedge block group 5, a limit lock 6, a discharge groove 7, a force application mechanism, a transmission plate 11, and a feeding mechanism 13, wherein the processing table 3 is mounted on the worktable 2 via the limit lock 6.

[0051] Two symmetrical sliding grooves are opened on the top shell wall of the worktable 2. The processing table 3 is slidably connected to the top of the worktable 2. There are four limit locks 6, in pairs, located on both sides of the processing table 3, for limiting the side of the processing table 3.

[0052] The processing table 3 consists of a base plate, slide bars, work station plate, and ribs. There are two slide bars, which are symmetrically arranged at the bottom of the base plate. The work station plate is located above the base plate. There are three ribs, which are linearly distributed horizontally between the base plate and the work station plate. The processing table 3 is slidably assembled on the worktable 2 by the slide bars cooperating with the slide grooves on the worktable 2. Both the processing table 3 and the worktable 2 have unloading ports at their centers, which are used as discharge ports for waste materials during the metal stamping process.

[0053] There are two stamping dies 4, which are symmetrically arranged on the top of the processing table 3. The arrangement of the two stamping dies 4 can realize efficient dual-station production of metal materials.

[0054] The force-bearing wedge block group 5 is set on the top of the rear stamping die 4. The unloading chute 7 is fixedly connected to the left outer wall of the equipment frame 1001 by bolts. It is used to collect and guide the formed lamp parts on the stamping die 4. A collection box located on the ground can be placed below the bottom of the unloading chute 7 to collect the stamped lamp parts.

[0055] The feeding mechanism 13 is located on the outer right side of the equipment frame 1001 and is used to supply materials to the stamping die 4;

[0056] The force application mechanism includes a base plate 8, a lateral limiting member 9, a force application assembly 10, a transmission plate 11, and a force application column assembly 12. The base plate 8 is mounted on the loading plate 1003 via the lateral limiting member 9.

[0057] The force application component 10 and the force application column group 12 are both installed on the bottom of the base plate 8. The force application component 10 is used for the stamping force of the rear stamping die 4, and the force application column group 12 is used for the stamping force of the front stamping die 4. The force application mechanism and the feeding mechanism 13 are linked through the transmission plate 11.

[0058] When the force-applying mechanism is at its highest point, the force-applying column group 12 will not contact the corresponding stamping die 4. At this time, the stamping die 4 is in the demolding state. With the help of the transmission plate 11, the feeding mechanism 13 can feed the corresponding metal material at this location. At this time, the force-applying component 10 applies force to the corresponding die 4 through the force-receiving wedge block group 5 to close the die, thereby realizing the stamping and forming of the metal material at this location. Conversely, when the force-applying mechanism is at its lowest point, the force-applying column group 12 applies force to the corresponding stamping die to close the die, while the force-applying component 10 cancels the force applied to the corresponding stamping die 4, allowing it to demold under its own reset action. The transmission plate 11 can then enable the feeding mechanism 13 to feed the corresponding metal material at this location.

[0059] Please see Figure 3 , Figure 4 and Figure 13 In this embodiment of the invention, the limiting lock 6 includes a contact plate 61, a threaded post 62, and an adjusting post 63. The threaded post 62 and the adjusting post 63 are both movably connected to the contact plate 61. The vertical cross-section of the contact plate 61 is Z-shaped, with a circular hole and a slot. A nut is provided on the inner wall of the circular hole. The threaded post 62 is movably connected to the nut. The outer surface of the adjusting post 63 is also threaded, and the top of the adjusting post 63 passes through the slot. The height of the adjusting post 63 is adjusted by the cooperation of a washer and a nut.

[0060] The side of the contact plate 61 contacts the processing table 3, the bottom end of the threaded column 62 is fixedly connected to the end plate for pressing against the worktable 2, and the bottom end of the adjusting column 63 is provided with a slider, which is slidably connected to the slide groove.

[0061] Please see Figures 3-6 In this embodiment of the invention, the stamping die 4 includes a bottom die body 41 fixedly connected to the processing table 3 by bolts. Spring telescopic rods 42 are installed at the four corners of the top of the bottom die body 41. The top of the four spring telescopic rods 42 are jointly installed on the top of the top of the top die body 43. The bottom die body 41 is also provided with a die hole for forming lamp parts. A demolding component 44 for quick demolding of lamp parts is provided in the die hole. After the top die body 43 is subjected to force and moves downward, each spring telescopic rod 42 retracts. After the top die body 43 closes with the bottom die body 41, the stamping forming of the lamp connection is realized.

[0062] The demolding component 44 includes an inner grooved hole on the inner wall of the bottom of the mold hole. A spring telescopic rod 441 is threaded into the inner grooved hole. The output end of the spring telescopic rod 441 is screwed onto a top plate 442 for supporting the lamp parts. The demolding component 44 can be easily disassembled and assembled through the inner grooved hole on the inner wall of the bottom of the mold hole via the spring telescopic rod 441. When the lamp parts are stamped, the demolding component 44 is installed so that when the top mold body 43 moves upward to demold, the spring telescopic rod 441 drives the top plate 442 to reset, thereby automatically demolding the lamp parts located in the mold hole and unloading the lamp parts.

[0063] The force-bearing wedge block group 5 consists of two force-bearing wedge blocks, which are symmetrically arranged on the top of the rear top die body 43. Through the arrangement of the force-bearing wedge block group 5, the stamping force is applied to the stamping die 4 when the force-applying component 10 moves.

[0064] Please see Figure 1 , Figure 7 and Figure 8 In this embodiment of the invention, the substrate 8 is slidably connected to the bottom shell wall of the loading plate 1003, and there are two lateral limiting members 9, which are also slidably connected to the bottom shell wall of the loading plate 1003. The two lateral limiting members 9 are located on both sides of the substrate 8, and are used to press and limit the substrate 8.

[0065] The two lateral limiting members 9 are used to press and limit the two side shell walls of the substrate 8, thereby enabling convenient disassembly and assembly of the substrate 8.

[0066] The lateral limiting member 9 includes an L-shaped plate for abutting against the substrate 8. The top of the L-shaped plate is slidably connected to the loading plate 1003. A through hole is provided in the middle of the L-shaped plate. An inner threaded ring is rotatably connected to the bottom of the through hole. A lead screw is threaded into the inner threaded ring. The top of the lead screw passes through the through hole and is mounted on a tray. The tray abuts against and limits the bottom shell wall of the loading plate 1003.

[0067] The force application component 10 includes a straight plate 101 fixedly connected to the bottom shell wall of the base plate 8 by bolts. A T-shaped frame 102 located on the worktable 2 is provided on the front side of the straight plate 101. A straight groove is provided on the T-shaped frame 102. Two moving blocks are slidably connected in the straight groove. A support rod is fixedly connected to the front side of each moving block. A force application wedge 103 is fixedly connected to the front end of the support rod. The force application wedge 103 is in sliding contact with the corresponding force receiving wedge. Two inclined grooves are symmetrically provided on the straight plate 101. A protruding rod is slidably connected in each inclined groove. The front ends of the two protruding rods are respectively fixedly connected to the corresponding moving blocks.

[0068] When the straight plate 101 moves up and down, the inclined groove arranged on it moves vertically. With the cooperation of the straight groove on the T-shaped frame 102, when the straight plate 101 moves up and down, each protruding rod drives the corresponding moving block to make lateral adjustment, thereby driving the corresponding force wedge 103 to move. When the force wedge 103 squeezes the force wedge in the force wedge block group 5, it drives the top die body 43 in the corresponding stamping die 4 to move down.

[0069] The force-applying column group 12 is composed of multiple force-applying columns, which are arranged laterally and linearly on the bottom shell wall of the substrate 8. The number of force-applying columns in the force-applying column group 12 ranges from three to six. In this embodiment, three are used. The three force-applying columns move synchronously with the downward movement of the substrate 8, thereby applying force to drive the top die body 43 in the corresponding stamping die 4.

[0070] Please see Figure 1 and Figures 9-12 In this embodiment of the invention, the feeding mechanism 13 includes a bracket that is fixedly connected to the outer right wall of the equipment frame 1001 by bolts. The top of the bracket is provided with a main box 131. A U-shaped frame 132 is welded to the center of the main box 131. A drive assembly 133 is movably connected to the top of the U-shaped frame 132. The front and rear sides of the U-shaped frame 132 are provided with a feeding assembly 134, a wiping assembly 135, an oiling assembly 136 and an oil guide groove 137 located inside the main box 131. The U-shaped frame 132 is positioned at the center of the main box 131 so that the drive assembly 133 on it can contact the corresponding structure when it moves a certain distance back and forth.

[0071] The feeding assembly 134 is used for feeding metal materials, the wiping assembly 135 is used for wiping and cleaning the feeding assembly 134 to prevent the feeding assembly 134 from slipping when feeding metal materials due to the protective oil attached to it, thus ensuring the feeding distance of the metal materials, the oiling assembly 136 is used for applying protective oil to the metal materials to ensure the uniformity of the protective oil on the metal materials entering the stamping die 4, and the oil guide groove 137 is used for collecting and guiding excess protective oil.

[0072] The main box 131 includes a box body 1311 fixedly connected to the top of the bracket. The box body 1311 has partitions 1312 arranged symmetrically in front and back. The arrangement of the two partitions 1312 divides the internal space of the box body 1311 into three spaces: the middle feeding space and the oil storage spaces on both sides.

[0073] Each partition 1312 has an integrally formed horizontal plate 1313 on its outer side. The upper part of the horizontal plate 1313 is used to store the protective oil to be used, and the lower part of the horizontal plate 1313 is used to store waste oil. The horizontal plate 1313 makes the interior of the oil storage space form two separate spaces for storing protective oil in different states. The bottom shell wall of the oil storage space for storing waste oil is provided with a discharge pipe for convenient waste oil treatment.

[0074] Each horizontal plate 1313 has an opening on the partition plate 1312 below it. Two oil guide grooves 137 are fixedly connected to the left inner wall of the box 1311. The bottom end of the oil guide groove 137 passes through the corresponding opening and extends to the bottom of the corresponding horizontal plate 1313. The oil guide groove 137 is set to collect and guide the protective oil that falls after use, so as to avoid waste of resources and avoid contamination of the feeding space.

[0075] The top of the housing 1311 has an access port, and an access plate 1314 is installed in the access port by bolts.

[0076] The top of the U-shaped frame 132 is integrally provided with a slide rail. A rectangular through slot is provided on the left side of the slide rail, which is located on the corresponding shell wall of the housing 1311. The drive assembly 133 includes a moving arm 1331 slidably connected to the slide rail. The left end of the moving arm 1331 passes through the rectangular through slot and is equipped with a rod. A dual-axis motor is provided on the right side of the moving arm 1331. A drive gear 1332 and a friction cone 1333 are installed on both output ends of the dual-axis motor. The friction cone 1333 is located outside the drive gear 1332.

[0077] The transmission plate 11 is fixedly connected to the base plate 8 by bolts, and a guide groove is provided on the side wall of the transmission plate 11, and the rod body is slidably connected to the guide groove.

[0078] When the transmission plate 11 is raised or lowered, the guide groove on it drives the rod to move, thereby adjusting the position of the moving arm 1331 in the drive assembly 133. After the moving arm 1331 is adjusted, the dual-axis motor on it drives each drive gear 1332 to adjust synchronously with the friction cone 1333.

[0079] The feeding assembly 134 includes two feeding rollers 1341 arranged symmetrically at the top and bottom. Each feeding roller 1341 is equipped with a transmission gear 1342, and the two transmission gears 1342 mesh with each other. The upper feeding roller 1341 is also equipped with a driven gear 1343. A gap for metal material to pass through is provided between the two feeding rollers 1341. Passage openings are provided on the corresponding side walls of the housing 1311 on both sides of the gap.

[0080] The feed roller 1341 includes a rotating shaft. The two ends of the rotating shaft are rotatably connected to the corresponding partition plate 1312 and the corresponding side wall of the U-shaped frame 132 through bearings. A material conveying sleeve is sleeved in the middle of the outer ring of the rotating shaft. The transmission gear 1342 and the driven gear 1343 are both located on the rotating shaft. The two feed rollers 1341 move in opposite directions under the meshing transmission action of the transmission gear 1342, thereby realizing the feeding of metal materials.

[0081] The wiping assembly 135 includes a cleaning component 1351 slidably connected to the inner wall of the right side of the housing 1311. Above the cleaning component 1351 is a reciprocating screw 1352 located inside the housing 1311. A conical sleeve 1353 is integrally provided at the end of the reciprocating screw 1352. The conical sleeve 1353 is movably inserted into the friction cone 1333.

[0082] The inner cavity of the tapered sleeve 1353 is provided with a rubber pad to improve friction, and the outer surface of the friction cone 1333 is also provided with a friction pad, so that when the friction cone 1333 is inserted into the tapered sleeve 1353, it can drive the reciprocating screw 1352 to perform stable rotational motion.

[0083] The cleaning component 1351 includes two arc-shaped cleaning plates arranged symmetrically at the top and bottom. The two arc-shaped cleaning plates correspond to the corresponding feed rollers 1341. The front and rear sides of the two arc-shaped cleaning plates are integrated by strip plates. The strip plates are slidably connected to the inner wall of the right side of the housing 1311. The top of the two strip plates is integrally provided with end plates, so that the cleaning component 1351 forms an integral structure.

[0084] Two supports are movably connected to the reciprocating screw 1352. The side walls of the supports are fixedly connected to the inner right side wall of the housing 1311 by bolts. An adjusting arm located on the reciprocating screw 1352 is threaded between the two supports, and the bottom end of the adjusting arm is fixedly connected to the cleaning component 1351. When the reciprocating screw 1352 rotates, it drives the adjusting arm to perform a back-and-forth reciprocating motion, which in turn causes the cleaning component 1351 to reciprocate, thereby wiping and cleaning the feed roller 1341 during the rotation process.

[0085] The oiling assembly 136 includes a liquid pump body 1361, an applicator 1362, and a three-way connector 1363. The liquid pump body 1361 is disposed on the left inner wall of the housing 1311. There are two applicators 1362, which are symmetrically distributed vertically. The two applicators 1362 are disposed on the left inner wall of the housing 1311 by a mounting bracket assembly and are used for recoating the protective oil on metal materials.

[0086] During the feeding motion of the metal material, as the metal material passes through the two coating parts 1362, the coating parts 1362 can apply protective oil to the surface of the metal material.

[0087] The two coating parts 1362 are connected by a three-way fitting 1363. The three-way fitting 1363 is connected to the liquid pump body 1361 through an oil supply pipe. The feed end of the liquid pump body 1361 is equipped with a conduit.

[0088] The main body of the pump 1361 pumps the protective oil to be used into the three-way fitting 1363 for diversion, and then into each coating component 1362.

[0089] The coating component 1362 includes a hollow tube 13621 and an oiling sleeve 13622. The outer shell of the hollow tube 13621 has an annular groove, and multiple oil spray holes are formed along the circumferential direction on the peripheral wall of the annular groove. The oiling sleeve 13622 is rotatably connected to the annular groove for absorbing the protective oil. The oiling sleeve 13622 is used for applying the protective oil and can be made of various materials. In this embodiment, a sponge material is used to absorb the sprayed protective oil, and then the protective oil is applied to the metal material by rotational motion during metal material feeding.

[0090] The working principle of the present invention is as follows: In the initial state of the equipment, the power unit 1002 in the stamping equipment 1000 drives the loading plate 1003 to the highest position. At this time, the force application mechanism and transmission plate 11 set on the loading plate 1003 are also at the highest point.

[0091] When the force-applying mechanism is at its highest point, the force-applying column group 12 in the force-applying mechanism is above the front stamping die 4. Each spring telescopic rod 42 in the stamping die 4 is in its initial state, causing the top die body 43 and the bottom die body 41 to separate from each other. The straight plate 101 in the force-applying component 10 moves up to its maximum mileage with the loading plate 1003. The position of the straight plate 101 at this time causes the convex rod connected to its upper inclined groove to drive the corresponding moving blocks to move closer to each other when the straight groove in the T-shaped frame 102 is engaged. Then, each force-applying wedge block 103 squeezes and applies force to the force-receiving wedge block group 5 on the rear stamping die 4 when they move closer to each other, so that the top die body 43 and the corresponding bottom die body 41 in the stamping die 4 close the mold and compress the corresponding spring telescopic rod 42, thereby realizing the stamping of the metal material in the stamping die 4.

[0092] When the transmission plate 11 is at its highest point, the rod in the guide groove on it drives the drive assembly 133 in the feeding mechanism 13 to move forward as a whole. This causes the drive gear 1332 on the front output end of the dual-axis motor in the drive assembly 133 to move synchronously with the friction cone 1333. At this time, the drive gear 1332 meshes with the driven gear 1343 in the feeding assembly 134 at the front position of the U-shaped frame 132, while the friction cone 1333 is inserted into the conical sleeve 1353 in the corresponding wiping assembly 135. As the drive assembly 133 moves forward as a whole, the drive gear 1332 and the friction cone 1333 on the rear output end of the dual-axis motor disengage from the corresponding feeding assembly 134 and wiping assembly 135.

[0093] When stamping lamp parts, the equipment is started by the external control cabinet. The program in the control cabinet first turns on the dual-axis motor of the drive component 133 in the feeding mechanism 13 and the liquid pump body 1361 in the front oiling component 136. The dual-axis motor drives each drive gear 1332 to move with the friction cone 1333. At this time, the dual-axis motor runs for a certain period of time under the control of the program in the control cabinet to ensure the number of rotations of the drive gear 1332 and the friction cone 1333.

[0094] Then, the driving gear 1332, which is in contact with the corresponding driven gear 1343, drives the corresponding feeding roller 1341 in the feeding assembly 134 to move during rotation. When the feeding roller 1341 rotates, the transmission gear 1342 on it moves synchronously. The two feeding rollers 1341 in the same feeding assembly 134 have their transmission gears 1342 meshing and driving each other, thereby making the two feeding rollers 1341 in the feeding assembly 134 move and realize the feeding of the current metal material.

[0095] The conical sleeve 1353, which is inserted into the corresponding friction cone 1333, drives the corresponding reciprocating screw 1352 to rotate when the friction cone 1333 moves. During the rotation, the reciprocating screw 1352 causes the corresponding cleaning component 1351 to move back and forth through the adjusting arm connected by bolts on it, thereby wiping and cleaning the moving feed roller 1341.

[0096] The main body of the pump 1361 intermittently pumps protective oil under the control of the program in the main body of the control cabinet. After running for a period of time, the main body of the pump 1361 shuts down automatically. The protective oil is transported to the three-way fitting 1363 by the oil delivery pipe, and then diverted to the corresponding coating parts 1362. During the feeding process, the metal material comes into contact with the two coating parts 1362 in the corresponding oiling component 136, and then the upper and lower surfaces of the fed metal material are coated with protective oil. The coated metal material is fed forward to the stamping die 4 at the front position by the feeding component 134 for one unit distance. As the metal material is fed, the lamp parts that have been stamped on the stamping die 4 fall into the unloading groove 7 under the push of the metal material feeding. Under the guidance of the unloading groove 7, the material is unloaded by sliding.

[0097] After the program in the main body of the control cabinet completes the operation of the loading mechanism 13, it shuts down the dual-axis motor and then controls the power unit 1002 in the stamping equipment 1000 to move, causing the loading plate 1003 to move downward. When the power unit 1002 moves half a circle, the loading plate 1003 moves to the lowest point. At this time, under the control of the program in the main body of the control cabinet, the power unit 1002 stops moving. After the loading plate 1003 reaches the lowest point, the force application mechanism and transmission plate 11 on it also reach the lowest point position. At this time, the force application column group 12 on the base plate 8 applies force to the stamping die 4 at the front position, causing the stamping die 4 to perform a mold closing movement, thereby completing the stamping forming of the lamp parts.

[0098] As the substrate 8 moves downward, the straight plate 101 in the force application assembly 10 moves downward. At this time, under the action of the straight groove on the T-shaped frame 102, each force application wedge 103 moves to both sides, thereby canceling the squeezing force on the force wedge on the stamping die 4 at the rear position. At this time, each spring telescopic rod 42 in the stamping die 4 resets, so that the top die body 43 and the bottom die body 41 are demolded.

[0099] When the transmission plate 11 reaches the lowest point, it drives the drive component 133 in the feeding mechanism 13 to move backward as a whole through the rod. After the drive component 133 moves backward, the drive gear 1332 and friction cone 1333 on the front output end of its dual-axis motor disengage from the feeding component 134 and wiping component 135 at the front position. Meanwhile, the drive gear 1332 and friction cone 1333 on the rear output end of the dual-axis motor contact the feeding component 134 and wiping component 135 at the rear position. The contact method is as described above. During the time when the power unit 1002 is paused, the program in the control cabinet controls the operation of the dual-axis motor and the liquid pump body 1361 in the oiling component 136 at the rear position.

[0100] The dual-axis motor drives the corresponding feeding assembly 134 and wiping assembly 135 through the corresponding drive gear 1332 and friction cone 1333, thereby driving the corresponding metal material to be fed, while the oiling assembly 136 performs a surface protective oil recoating treatment on the metal material during the feeding process.

[0101] After the loading mechanism 13 is completed, the program in the control cabinet closes the structure inside the loading mechanism 13 again, and then drives the power unit 1002 in the stamping equipment 1000 to run, which again moves the loading plate 1003 to the highest point, repeating the cycle, thereby realizing the efficient stamping production of lamp parts in a dual-station manner.

[0102] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
