Description

A fastening washer forming device Technical Field

[0001] This utility model belongs to the field of gasket processing technology, specifically relating to a fastening gasket forming device. Background Technology

[0002] Fastening washers are mechanical parts used to enhance the stability of fastener connections. They are typically made of flat metal rings and their main functions include cushioning, isolation, sealing, and preventing loosening. Currently, fastening washers are usually manufactured by processing steel strips using stamping dies.

[0003] In related prior art, such as Chinese Patent No. CN222343964U, a gasket stamping die is disclosed. The solution includes a lower die and an upper die. The lower die is provided with a central scrap punch arranged at the rear and a gasket finished product punch arranged at the front. The upper die is provided with a scrap punch matching the central scrap punch and a finished product punch matching the gasket finished product punch. The above solution utilizes a scrap receiving slope plate set below the central scrap punch and a finished product receiving slope plate set below the gasket finished product punch to realize the function of separate collection of scrap and finished products, eliminating the need for secondary screening and indirectly improving processing efficiency.

[0004] In the above-mentioned process, to collect waste and finished products, collection frames need to be placed below the bottom of the waste collection ramp and the finished product collection ramp, respectively. When the collection frame is full of waste or finished product, it needs to be replaced. In some processing methods, to prevent waste or finished product from scattering onto the ground, the stamping operation needs to be paused, thus slowing down the production rate. Summary of the Invention

[0005] The present invention aims to provide a fastening washer forming device to solve the problem that the above-mentioned solution slows down the production rate during the replacement of the collection frame.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fastening washer forming device includes a worktable and a material guiding assembly. The worktable has a vertically penetrating channel, in which a lower mold is fixedly embedded. A support plate is fixedly mounted above the worktable, and a drive module is fixedly mounted on the support plate. An upper mold is fixedly connected between the output end of the drive module and the support plate. The top of the lower mold has two through holes of different sizes spaced apart. The bottom of the upper mold has a pressure block that mates with the two through holes. The material guiding assembly includes a vertical rod disposed at the bottom of the lower mold between the two through holes and guide plates disposed below the two through holes. The top of one end of the guide plate is rotatably connected to the bottom of the lower mold. Support rods that can contact the bottom of the corresponding guide plates are fixedly mounted at both ends of the bottom of the vertical rod. The top of the other end of the guide plate can be hung on the worktable by a hanging assembly. When the other end of the guide plate is hung on the worktable, the bottom of the guide plate is spaced apart from the support rod.

[0008] The principle and effects of this technical solution:

[0009] In the initial state, the bottoms of the two guide plates are placed on the support rod, and both guide plates are tilted. Before making the fastening washer, a collection frame is placed below the bottom of the two guide plates. When making the fastening washer, the steel strip is intermittently moved from left to right between the upper and lower molds using a stepping conveyor mechanism. When the steel strip stops moving, the upper mold is lowered using a drive module. The smaller pressing block passes through the steel strip and presses out the center notch of the washer. The waste material falls into one of the collection frames through the smaller through hole and the guide plate below it. The steel strip is moved again so that the larger pressing block passes through the steel strip along the axis of the center notch, and the finished fastening washer is pushed out through the larger through hole. The finished product falls into the other collection frame through the other guide plate. When the collection frame is full, the guide plate above the full collection frame is hung on the workbench using a hanging assembly. At this time, the bottom of the guide plate is detached from the support rod and is in a horizontal state, and the waste material or finished product cannot slide along the guide plate.

[0010] With the above setup, the guide plate is hung on the workbench using the hanging assembly. When the collection box is full, the guide plate can be adjusted to a horizontal position, allowing the horizontal guide plate to receive waste or finished products. This enables workers to replace the collection box without interrupting the stamping process, ensuring production efficiency.

[0011] In this utility model, the hanging assembly includes hooks fixedly disposed on both sides of the top of the other end of the guide plate, a connecting seat fixedly disposed on the outer side wall of the workbench, and the hanging assembly also includes connecting ears rotatably disposed on both sides of the connecting seat. A crossbar is fixedly disposed between the two connecting ears, and the hooks can be hung on the corresponding crossbar.

[0012] The principle and effects of this technical solution:

[0013] When it is necessary to hang the guide plate, first rotate the guide plate upward. After the hook at the top of the guide plate contacts the crossbar, first push the crossbar to rotate away from the worktable. Continue to rotate the guide plate. When the hook moves above the crossbar, the crossbar resets under the action of gravity. At this time, rotate the guide plate in the opposite direction to hang the hook on the crossbar.

[0014] The above settings achieve the purpose of hanging the guide plate on the workbench.

[0015] In this invention, baffles are fixedly installed on both sides of the top of the guide plate, and the two hooks are respectively fixedly installed on the top of the corresponding baffles. This arrangement prevents waste and finished products from escaping from the long side of the guide plate, thus improving the collection efficiency of the device for waste and finished products.

[0016] In this utility model, the lower mold has a through groove between the two through holes, the top of the vertical rod is slidably inserted into the groove, the vertical rod is fitted with a tension spring, the two ends of the tension spring are respectively connected to the bottom of the lower mold and the bottom of the vertical rod, and the bottom of the upper mold is fixedly provided with a protrusion that cooperates with the groove.

[0017] The principle and effects of this technical solution:

[0018] When the upper mold moves downward, the protrusion passes through the scrap notch on the steel plate and inserts into the chute, dragging the vertical rod and its bottom support rod downward. The guide plate placed on the support rod rotates accordingly. When the upper mold moves upward, the tension spring pulls the vertical rod and its bottom support rod to reset. During this process, the support rod pushes the guide plate to rotate in the opposite direction.

[0019] With the above setup, the vertical rod is moved up and down by the protrusion and tension spring, which in turn causes the guide plate to vibrate, shaking off the waste or finished product on the surface of the guide plate and preventing material jamming.

[0020] In this invention, a limiting strip protrudes from the inner wall of the slide groove, and a limiting groove is vertically formed at the top of the outer wall of the vertical rod. The limiting strip is slidably embedded in the limiting groove. This design prevents the vertical rod from rotating and also prevents the top of the vertical rod from obstructing the movement of the steel strip.

[0021] In this invention, a guide assembly is further provided on the top of the workbench. The guide assembly includes two guide units symmetrically arranged on the left and right sides of the upper mold. Each guide unit includes two fixed shafts symmetrically arranged front and back and fixedly mounted on the workbench. A guide roller is rotatably sleeved on the outside of each fixed shaft. Through the above arrangement, the steel strip can be guided, preventing the steel strip from moving in the front-back direction and improving the forming effect of the fastening washer.

[0022] In this invention, each of the fixed shafts has a limiting block threaded onto its top. This arrangement allows the top of the steel strip to slide against the bottom of the limiting block, preventing the steel strip from moving vertically and improving the forming effect of the fastening washer.

[0023] In this invention, multiple guide rods are fixedly arranged at intervals between the worktable and the support plate, and the upper mold is slidably sleeved on the multiple guide rods. This arrangement further improves the forming effect of the fastening washer. Attached Figure Description

Support rods 41 that can contact the bottom of the corresponding material guiding plate 50 are fixedly disposed at both ends of the bottom of the vertical rod 40. The top of the other end of the material guiding plate 50 can be hung on the worktable 10 by a hanging assembly. When the other end of the material guiding plate 50 is hung on the worktable 10, the bottom of the material guiding plate 50 and the support rods 41 are spaced apart. The lifting module 12 is configured as an electric cylinder or similar structure.

[0034] In this embodiment, the hanging assembly includes hooks 61 fixedly disposed on both sides of the top of the other end of the guide plate 50, a connecting seat 13 fixedly disposed on the outer side wall of the workbench 10, and the hanging assembly also includes connecting ears 62 rotatably disposed on both sides of the connecting seat 13. A crossbar 63 is fixedly disposed between the two connecting ears 62, and the hooks 61 can be hung on the corresponding crossbar 63.

[0035] In this embodiment, baffles 51 are fixedly provided on both sides of the top of the guide plate 50, and the two hooks 61 are respectively fixedly provided on the top of the corresponding baffles 51.

[0036] In this embodiment, the lower mold 20 has a vertically penetrating groove 22 between the two through holes 21. The inner diameter of the groove 22 is smaller than the inner diameter of the smaller through hole 21. The top of the vertical rod 40 is slidably inserted into the groove 22. The vertical rod 40 is fitted with a tension spring 42. The two ends of the tension spring 42 are respectively connected to the bottom of the lower mold 20 and the bottom of the vertical rod 40. The bottom of the upper mold 30 is fixedly provided with a protrusion 32 that cooperates with the groove 22.

[0037] In this embodiment, the inner sidewall of the slide groove 22 is provided with a limiting strip 23, and the top of the outer sidewall of the vertical rod 40 is provided with a limiting groove 43 in the vertical direction. The limiting strip 23 is slidably embedded in the limiting groove 43. When the bottom wall of the limiting groove 43 abuts against the bottom of the limiting strip 23, the top surface of the vertical rod 40 is lower than the top surface of the lower mold 20.

[0038] In this embodiment, a guide assembly is also provided on the top of the workbench 10. The guide assembly includes two guide units symmetrically arranged on the left and right sides of the upper mold 30. The guide unit includes two fixed shafts 70 symmetrically arranged on the workbench 10. Each fixed shaft 70 is rotatably sleeved with a guide roller 71.

[0039] In this embodiment, each of the fixed shafts 70 is threaded with a limiting block 72 on its top.

[0040] In this embodiment, a plurality of guide rods 14 are fixedly arranged at intervals between the workbench 10 and the support plate 11, and the upper mold 30 is slidably sleeved on the plurality of guide rods 14.

[0041] The specific implementation process is as follows:

[0042] In the initial state, the bottoms of the two guide plates 50 are placed on the support rod 41, and both guide plates 50 are in an inclined state. Before making the fastening washer, a collection frame is placed below the bottom of the two guide plates 50. When making the fastening washer, the steel strip is intermittently moved from left to right between the upper mold 30 and the lower mold 20 using a stepping conveyor mechanism. When the steel strip stops moving, the upper mold 30 is lowered using the drive module 12. After the smaller pressing block 31 passes through the steel strip, it presses out the center notch of the washer. The waste material passes through the smaller through hole 21 and the hole below it. The guide plate 50 falls into one of the collection boxes. The steel belt is moved again, so that the larger pressure block 31 passes through the steel belt along the central notch axis, and the finished fastening washer is pushed out through the larger through hole 21. The finished product falls into another collection box through another guide plate 50. When the collection box is full, the guide plate 50 above the full collection box is hung on the workbench 10 using the hanging assembly. At this time, the bottom of the guide plate 50 is detached from the support rod 41 and is in a horizontal state. Waste or finished products cannot slide along the guide plate 50. The stepping conveyor mechanism is a product that can be purchased on the market.

[0043] When it is necessary to hang the guide plate 50, first rotate the guide plate 50 upward. After the hook 61 at the top of the guide plate 50 contacts the crossbar, first push the crossbar 63 to rotate away from the worktable 10. Continue to rotate the guide plate 50. When the hook 61 moves above the crossbar, the crossbar 63 returns to its original position under the action of gravity. At this time, rotate the guide plate 50 in the opposite direction to hang the hook 61 on the crossbar 63.

[0044] When the upper mold 30 moves downward, the protrusion 32 passes through the scrap notch on the steel plate and inserts into the slide groove 22, dragging the vertical rod 40 and its bottom support rod 41 downward. The guide plate 50 placed on the support rod 41 rotates accordingly. When the upper mold 30 moves upward, the tension spring 42 pulls the vertical rod 40 and its bottom support rod 41 to reset. During this process, the support rod 41 pushes the guide plate 50 to rotate in the opposite direction.
