Description

Technical Field

[0001] This invention relates to the field of clamp stamping technology, and in particular to a stamping machine for double-convex clamp parts. Background Technology

[0002] Double-convex clamp parts are widely used in pipe connections, mechanical fastening and other fields. Their stamping process has high requirements for the symmetry of the double-convex structure, the uniformity of edge clamping force and the flexibility of material feeding and discharging.

[0003] The existing method of stamping and forming clamps involves multiple steps. Two of these steps are: Step 1 - punching through holes at both ends of the iron strip to facilitate bolt installation, and Step 2 - stamping the iron plate with the punched through holes into a U-shaped clamp. This separate processing method is inefficient.

[0004] In addition, existing double-convex clamp stamping equipment has the following problems: during the stamping process, the raw material is prone to asymmetry of the double-convex structure due to lateral flow or local displacement, so manual secondary correction is required, which affects the yield. Although most existing stamping forming machines are equipped with clamping devices, they mostly rely on additional power sources including independent cylinders, resulting in structural redundancy, high cost, and difficulty in synchronizing with the stamping action. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing technology has the disadvantages of the double convex part forming position deviation caused by the lateral displacement of the part during the stamping process, low operation efficiency and safety risks, and the part deformation or displacement caused by improper clamping force. To this end, we propose a stamping forming machine for double convex clamp parts.

[0006] To achieve the above objectives, this application adopts the following technical solution: a double-convex clamp part stamping forming machine, including a worktable, on the upper surface of the worktable a feeding and discharging mechanism and a transparent cover are fixedly installed, a lower stamping mechanism is installed on the feeding and discharging mechanism, a first cylinder is fixedly installed on the upper surface of the transparent cover, the output end of the first cylinder extends into the interior of the transparent cover, and the output end of the first cylinder is fixedly connected to the upper stamping mechanism;

[0007] The feeding and discharging mechanism drives the lower stamping mechanism to move so that when the lower stamping mechanism moves to the stamping position, it fits with the upper stamping mechanism to complete the stamping forming of the double convex clamp part. After the upper stamping mechanism completes the stamping, it drives the lower stamping mechanism away from the outside of the transparent cover, realizing the positioning stamping of the upper stamping mechanism and the lower stamping mechanism and the flexible feeding and discharging of the feeding and discharging mechanism.

[0008] A dynamic offset displacement mechanism is fixedly and symmetrically installed on both sides of the upper stamping mechanism. The dynamic offset displacement mechanism is linked with the upper stamping mechanism so that when the upper stamping mechanism presses down, it drives the dynamic offset displacement mechanism to synchronously abut against the lower stamping mechanism. Through horizontal force drive, a clamping driving force is realized for the dynamic displacement of the double convex clamping parts on both sides of the lower stamping mechanism.

[0009] A linkage mechanism is installed on the upper surface of the lower stamping mechanism. The linkage mechanism is driven by the dynamic offset displacement mechanism so that when the dynamic offset displacement mechanism pushes against the linkage mechanism, the linkage mechanism moves inward relative to the other side, thereby achieving dynamic clamping of the double convex clamping parts inside the lower stamping mechanism.

[0010] Preferably, the feeding / discharging mechanism includes:

[0011] The second cylinder has a displacement platform fixedly mounted on one output end. The two sides of the displacement platform are fixedly connected to inner displacement rail plates. The side of the worktable away from the second cylinder is symmetrically fixedly equipped with a slide rail assembly. The inner displacement rail plate is slidably connected inside the slide rail assembly.

[0012] Preferably, the upper stamping mechanism includes:

[0013] The upper stamping protrusion has screw hole stamping parts symmetrically connected to both sides of its two surfaces.

[0014] Preferably, the lower stamping mechanism includes:

[0015] A lower stamping table is fixedly installed on the upper surface of the displacement table. A lower stamping groove is formed on the center surface of the lower stamping table, and stamping holes are formed on the four corner surfaces of the lower stamping table away from the lower stamping groove. The stamping holes correspond to the position and size of the screw hole stamping part.

[0016] A protective frame is fixedly installed around the upper surface of the lower stamping table at the edge of the lower stamping groove. Through grooves are opened on both sides of the protective frame, and a protective plate is fixedly connected between the central bottom wall of the through groove and the upper surface of the lower stamping table.

[0017] Preferably, the dynamic displacement cancellation mechanism includes:

[0018] The wedge body has a side push block contact piece slidably connected inside the wedge body via a cylindrical pin. The two sides of the side push block contact piece are symmetrically provided with grooves. A guide plate is threadedly installed inside the groove. The guide plate and the groove are threadedly connected by a bolt.

[0019] Preferably, the linkage mechanism includes:

[0020] The side push block has guide grooves and slide grooves symmetrically distributed on the upper surfaces of both sides of the lower stamping table. The guide plate slides inside the guide groove, and a slide plate slides inside the slide groove. The upper surface of the slide plate is fixedly connected to the lower surface of the side push block. A spring and a fixing rod are fixedly welded to one side surface of the slide plate located in the slide groove. The spring is wrapped around the outside of the fixing rod, and the other end of the spring is welded to the inner wall of the other side of the slide groove. An inner sliding hole with the same size and position as the fixing rod is opened on the inner wall of the other side of the slide groove.

[0021] A movable clamping plate is fixedly connected to the side surface of the side push block away from the guide groove. The two ends of the movable clamping plate are provided with arc surfaces for fitting the double convex clamping parts. The center line surface of the side push block is provided with a slot that is the same size and position as the protective plate.

[0022] Preferably, a flip door is fixedly installed on one side surface of the transparent cover, and the surface of the flip door has an inlet and outlet for the lower stamping mechanism to feed and discharge materials;

[0023] The transparent cover has a slot on the side away from the flip door for securing the second cylinder.

[0024] Preferably, the transparent cover is provided outside part of the feeding and discharging mechanism, and one end of the displacement inner rail plate and the second cylinder are both located outside the transparent cover.

[0025] The technical effects and advantages of this invention are as follows:

[0026] In this invention, through the linkage design of the dynamic displacement offset mechanism and the linkage mechanism, when the upper stamping mechanism moves downward, the horizontal component of the wedge body drives the side push block contact piece, further pushing the side push block to slide along the guide groove, so that the moving clamping plate fits with the protrusions on both sides of the double convex clamp through the arc surface. At the same time, the cooperation between the spring and the fixed rod can dynamically adjust the clamping force according to the stamping pressure, so that when the pressure increases, the spring is compressed to provide buffer, thereby avoiding overpressure deformation, and when the pressure decreases, the spring rebounds to compensate for the displacement, ensuring gapless clamping throughout the process. This design effectively offsets the lateral displacement of the parts during the stamping process.

[0027] In this invention, the feeding and discharging mechanism drives the displacement table to slide along the slide rail assembly via the second cylinder, thereby realizing the automatic feeding and discharging of the lower stamping table. Specifically, during stamping, the displacement table is precisely positioned to the stamping position inside the transparent cover, fitting with the upper stamping mechanism. After stamping is completed, it automatically exits to the outside of the transparent cover without the need for manual intervention in positioning.

[0028] In addition, the design of the flip-up door and entrance / exit with the transparent cover not only avoids injury to operators from flying metal fragments, but also reduces the risk of mold damage caused by human error.

[0029] In this invention, the protective frame and protective plate on the edge of the lower stamping table can not only effectively prevent the debris generated during stamping from entering the guide groove, slide groove and other precision structures, reducing friction loss, but also ensure the stability of the double convex clamp parts during feeding and discharging. In addition, the matching design of the through groove and the slot provides guidance for the sliding of the linkage mechanism and avoids the side push block from deviating and getting stuck.

[0030] In addition, the precise correspondence between the screw hole stamping part and the stamping hole ensures the coaxiality of the die during the stamping process and reduces the die wear rate. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0043] Reference Figures 1-10 As shown, the present invention provides a technical solution: a double convex clamp part stamping forming machine, including a worktable 1, an infeed and discharge mechanism and a transparent cover 2 are fixedly installed on the upper surface of the worktable 1, a lower stamping mechanism is installed on the infeed and discharge mechanism, a first cylinder 8 is fixedly installed on the upper surface of the transparent cover 2, the output end of the first cylinder 8 penetrates into the interior of the transparent cover 2, and the output end of the first cylinder 8 is fixedly connected to the upper stamping mechanism;

[0044] The feeding and discharging mechanism drives the lower stamping mechanism to move so that when the lower stamping mechanism moves to the stamping position, it fits with the upper stamping mechanism to complete the stamping forming of the double convex clamp parts. After the upper stamping mechanism completes the stamping, it drives the lower stamping mechanism away from the outside of the transparent cover 2, so as to realize the positioning stamping of the upper and lower stamping mechanisms and the flexible feeding and discharging of the feeding and discharging mechanism.

[0045] The dynamic offset displacement mechanism is fixed and symmetrically installed on both sides of the upper stamping mechanism. The dynamic offset displacement mechanism is linked with the upper stamping mechanism so that when the upper stamping mechanism presses down, it drives the dynamic offset displacement mechanism to synchronously resist the lower stamping mechanism. Through the horizontal component force drive, the clamping driving force on the dynamic displacement of the double convex clamp parts inside the lower stamping mechanism is realized.

[0046] The linkage mechanism is installed on the upper surface of the lower stamping mechanism. The linkage mechanism is in transmission cooperation with the dynamic offset displacement mechanism so that when the dynamic offset displacement mechanism pushes the linkage mechanism, the linkage mechanism moves inward relative to the other side, thereby achieving dynamic offset clamping of the double convex clamp parts inside the lower stamping mechanism.

[0047] In this embodiment, firstly, the appendix Figure 10This is a schematic diagram of the finished product of the double-convex clamp part after stamping. In this embodiment, the double-convex clamp part is stamped using two dies of equal size, and then fastened together with bolts to obtain the desired product. Figure 10 The finished product;

[0048] The core of the double-convex clamp part stamping machine is supported by the worktable 1, which integrates the feeding and discharging mechanism that drives the lower stamping mechanism, the transparent cover 2 that protects the stamping environment, the first cylinder 8 that drives the upper stamping mechanism, and the dynamic offset displacement mechanism and linkage mechanism. The specific process is as follows:

[0049] Initial state: Place the double-convex clamp part to be processed into the lower stamping mechanism;

[0050] Feeding and positioning: When the feeding and discharging mechanism is started, it drives the lower stamping mechanism to move along the preset track into the transparent cover 2 until the lower stamping mechanism and the upper stamping mechanism are precisely aligned at the stamping position, and then the feeding and discharging mechanism automatically stops.

[0051] Stamping: After the lower stamping mechanism is in the stamping position, the first cylinder 8 is automatically started. The output end of the first cylinder 8 extends downward, pushing the upper stamping mechanism downward to fit with the lower stamping mechanism and complete the stamping of the double convex clamp.

[0052] Dynamic clamping: As the upper stamping mechanism moves downward, the dynamic offset displacement mechanisms on both sides simultaneously abut against the lower stamping mechanism, and drive the linkage mechanism through the horizontal component force, causing the linkage mechanism to move inward relative to each other, applying dynamic clamping force to both sides of the double convex clamp to offset the lateral displacement of the parts during the stamping process.

[0053] Material return and reset: After stamping is completed, the first cylinder 8 drives the upper stamping mechanism to rise and reset, and the feeding and discharging mechanism drives the lower stamping mechanism to exit the outside of the transparent cover 2, take out the finished product and place the new part to be processed, and enter the next cycle.

[0054] Thus, through the collaborative design of multiple mechanisms, the automated positioning and feeding / unloading of the lower stamping mechanism were achieved, avoiding positioning deviations caused by manual intervention;

[0055] The dynamic offset displacement mechanism and the linkage mechanism work together to clamp the parts, ensuring the stability of the parts during the stamping process and significantly improving the forming accuracy of the double convex clamp.

[0056] The enclosed environment of the transparent enclosure 2 effectively isolates stamping splashes and ensures operational safety.

[0057] Reference Figures 1-2 As shown in this embodiment, the feeding and discharging mechanism includes:

[0058] The second cylinder 4 has a displacement platform 15 fixedly mounted on one side of its output end. The two sides of the displacement platform 15 are fixedly connected to the inner displacement rail plate 16. The side of the worktable 1 away from the second cylinder 4 is symmetrically fixedly mounted with a slide rail assembly 7. The inner displacement rail plate 16 is slidably connected inside the slide rail assembly 7.

[0059] In this embodiment, the feeding and discharging mechanism consists of a second cylinder 4, a displacement table 15, a displacement inner rail plate 16, and a slide rail assembly 7. Its specific operations are as follows:

[0060] Feeding stage: The output end of the second cylinder 4 extends and pushes the displacement table 15 to slide along the slide rail group 7 towards the transparent cover 2. The displacement inner rail plates 16 on both sides of the displacement table 15 are embedded in the slide rail group 7 to ensure the straightness and stability of the sliding process.

[0061] Positioning stop: When the displacement table 15 moves to the stamping position inside the transparent cover 2, the second cylinder 4 stops operating, and the lower stamping mechanism is fixed on the displacement table 15 and precisely aligned with the upper stamping mechanism.

[0062] Material unloading stage: After the stamping is completed, the output end of the second cylinder 4 retracts, driving the displacement table 15 to slide in the opposite direction along the slide rail group 7 until the lower stamping mechanism completely exits the outside of the transparent cover 2, completing one feeding and discharging cycle.

[0063] The automatic linear movement of the lower stamping mechanism is achieved through the cooperation of the second cylinder 4 and the slide rail group 7, avoiding the risk of misalignment caused by manual handling.

[0064] The sliding design of the inner displacement rail plate 16 and the slide rail assembly 7 reduces friction loss and extends the service life of the mechanism.

[0065] Reference Figures 2-3 As shown, in this embodiment, the upper stamping mechanism includes:

[0066] The upper stamping protrusion 32 has screw hole stamping parts 9 symmetrically connected to both sides of the upper stamping protrusion 32.

[0067] The lower stamping mechanism includes:

[0068] The lower stamping table 17 is fixedly installed on the upper surface of the displacement table 15. The center surface of the lower stamping table 17 is provided with a lower stamping groove 18. The four corner surfaces of the lower stamping table 17 away from the lower stamping groove 18 are provided with stamping holes. The position and size of the stamping holes correspond to the screw hole stamping part 9.

[0069] A protective frame 19 is fixedly installed around the upper surface of the lower stamping table 17 located at the edge of the lower stamping groove 18. Through grooves 20 are opened on both sides of the protective frame 19. A protective plate 21 is fixedly connected between the central bottom wall of the through groove 20 and the upper surface of the lower stamping table 17.

[0070] In this embodiment, the coordinated operation of the upper stamping protrusion 32 and the screw hole stamping part 9 of the upper stamping mechanism with the lower stamping table 17, the lower stamping groove 18, the stamping hole and the protective frame 19 of the lower stamping mechanism is as follows:

[0071] Stamping preparation: After the lower stamping mechanism moves to the stamping position, the double convex clamp part to be processed is placed in the lower stamping groove 18 of the lower stamping table 17. The outline of the part matches the lower stamping groove 18, and the protective frame 19 and the protective plate 21 ensure that the double convex clamp part to be processed is stable on the lower stamping table 17.

[0072] Stamping: The first cylinder 8 drives the upper stamping protrusion 32 to move downward, and its bottom surface fits with the lower stamping groove 18, applying pressure to the double protrusion clamp to form a double protrusion structure on both sides. At the same time, the screw hole stamping parts 9 on both sides of the upper stamping protrusion 32 are simultaneously inserted into the stamping holes at the four corners of the lower stamping table 17 to stamp mounting screw holes on the parts.

[0073] Protective function: The protective frame 19 and protective plate 21 on the edge of the lower stamping table 17 prevent metal chips from flying during stamping and prevent chips from entering precision structures such as the guide groove 22. The through groove 20 provides guiding space for the sliding of the linkage mechanism and ensures the smoothness of the clamping action.

[0074] The cooperation between the upper stamping protrusion 32 and the lower stamping groove 18 ensures the precise forming of the double-convex structure;

[0075] The coaxial design of the screw hole stamping part 9 and the stamping hole avoids screw hole misalignment and improves the assembly adaptability of the parts;

[0076] The installation of the protective frame 19 and the protective plate 21 reduces the wear of debris on the mechanism and extends the equipment maintenance cycle.

[0077] Reference Figures 4-9 As shown, in this embodiment, the dynamic displacement cancellation mechanism includes:

[0078] The wedge body 10 has a side push block contact 11 slidably connected inside the wedge body 10 via a cylindrical pin. The two sides of the side push block contact 11 are symmetrically provided with grooves 12. The grooves 12 are threaded with guide plates 13. The guide plates 13 and the grooves 12 are threadedly connected with bolts 14.

[0079] The participating organizations include:

[0080] The upper surfaces of the side push block 23 and the lower punching table 17 are respectively provided with symmetrically distributed guide grooves 22 and sliding grooves 25. The guide plate 13 is slidably disposed inside the guide groove 22. The sliding plate 26 is slidably disposed inside the sliding groove 25. The upper surface of the sliding plate 26 is fixedly connected to the lower surface of the side push block 23. The sliding plate 26 is located on one side of the sliding groove 25 and a spring 28 and a fixing rod 27 are fixedly welded to it. The spring 28 is wrapped around the outside of the fixing rod 27, and the other end of the spring 28 is welded to the inner wall of the other side of the sliding groove 25. The inner wall of the other side of the sliding groove 25 is provided with an inner sliding hole 29 that is the same size and position as the fixing rod 27.

[0081] A movable clamping plate 24 is fixedly connected to the side surface of the side push block 23 away from the guide groove 22. The two ends of the movable clamping plate 24 are provided with arc surfaces 31 for fitting the double convex clamp parts. The center line surface of the side push block 23 is provided with a slot 30 that is the same size and position as the protective plate 21.

[0082] In this embodiment, the linkage action of the wedge body 10, the side push block contact 11, and the guide plate 13 of the dynamic displacement cancellation mechanism with the side push block 23, the slide plate 26, the spring 28, and the moving clamping plate 24 of the linkage mechanism is as follows:

[0083] Initial state: When the upper stamping mechanism is not in operation, the side push block 23 is located outside the slide groove 25 under the elastic force of the spring 28, and the moving clamp 24 maintains a gap with the double convex clamp part;

[0084] Stamping trigger clamping: When the upper stamping mechanism moves downward, the inclined wedge body 10 moves downward with the upper stamping protrusion 32, and its inclined surface abuts against the side push block contact 11. The side push block contact 11 is pushed to slide to both sides by the horizontal component force. The side push block contact 11 slides in the guide groove 22 through the guide plate 13, driving the side push block 23 to move inward along the slide groove 25.

[0085] Dynamic clamping and buffering: The side push block 23 pushes the moving clamping plate 24 to fit the protrusions on both sides of the double convex clamp through the arc surface 31. As the upper punching pressure increases, the spring 28 is compressed. The fixing rod 27 slides along the inner sliding hole 29 to provide guidance, buffering the excessive clamping force and avoiding deformation of the parts. When the pressure decreases, the spring 28 rebounds to compensate for the small displacement of the parts caused by the punching, ensuring gapless clamping throughout the process.

[0086] Reset and release: After the upper stamping mechanism rises, the wedge body 10 disengages from the side push block contact 11, the spring 28 returns to its original length, pushes the side push block 23 to reset, and the moving clamp 24 releases the parts.

[0087] The horizontal force conversion design of the wedge body 10 converts the vertical punching force into the lateral clamping force, requiring no additional power source, and has a compact structure and low energy consumption.

[0088] The cooperation between spring 28 and fixed rod 27 enables dynamic adjustment of clamping force—buffering against deformation when pressure increases and compensating against displacement when pressure decreases;

[0089] The curved surface 31 of the movable clamp 24 is designed to fit the contour of the double convex clamp, avoiding surface damage caused by local stress concentration.

[0090] Reference Figure 1 and Figure 2 As shown in this embodiment: a flip door 3 is fixedly installed on one side surface of the transparent cover 2, and the surface of the flip door 3 is provided with an inlet and outlet 5 for the lower stamping mechanism to feed and discharge materials;

[0091] The transparent cover 2 has a slot 6 on the side of the cover away from the flip door 3 for locking the second cylinder 4;

[0092] The transparent cover 2 is installed outside part of the feeding and discharging mechanism, and the displacement inner rail plate 16 and one end of the second cylinder 4 are both located outside the transparent cover 2.

[0093] In this embodiment, the transparent cover 2 achieves protection against the stamping environment and integration of the mechanism through the flip door 3, the inlet / outlet 5, and the equipment slot 6. The specific actions are as follows:

[0094] Feed protection: When the lower stamping mechanism is feeding, the flip door 3 remains closed. The lower stamping mechanism enters the interior of the transparent cover 2 through the inlet and outlet 5. The size of the inlet and outlet 5 only allows the lower stamping mechanism to pass through, reducing the entry of external debris.

[0095] Stamping isolation: During the stamping process, the transparent cover 2 is completely sealed to prevent metal shavings, oil stains and other splashes from spilling out. Operators can observe the internal stamping status through the transparent cover 2.

[0096] Equipment installation and maintenance: The second cylinder 4 is fixed to the outside of the transparent cover 2 through the equipment slot 6, and its output end extends through to the inside and connects to the displacement table 15. When maintenance is required, the internal mechanism can be directly accessed by opening the flip door 3, making operation convenient.

[0097] Specifically, the enclosed design of the transparent housing 2 isolates the stamping area from the external operating area, reducing the risk of operators being injured by flying debris;

[0098] The narrow opening design of the inlet and outlet 5 reduces the entry of external dust and extends the service life of precision components such as the slide rail assembly 7 and the guide groove 22.

[0099] The external mounting method of the equipment slot 6 avoids the second cylinder 4 from being exposed to the stamping splash environment, reducing the wear of the cylinder seals.
