Description

Technical Field

[0001] The present application relates to the technical field of continuous molds, and in particular to a continuous mold for processing a slideway retainer of an automobile seat. Background Art

[0002] The slide retainer of the automobile seat has a small shape, high matching requirements, and large production batches. It is usually processed and formed by a continuous die. A continuous die refers to a die that completes multiple processes at several different positions in a single stroke of the press. It has a high degree of automation and is now widely used in the production and processing of automobile parts. During the continuous die stamping process, the metal components on the lower die will produce a certain amount of waste after stamping. The waste will fall and accumulate inside the waste cavity under the lower die. However, due to the small space of the waste cavity, the waste storage capacity is limited. During the continuous die production, it is necessary to frequently stop the machine to clean up the waste accumulated in the waste cavity, which increases the time for the staff to clean up the waste and affects the production efficiency.

[0003] Through searching, Chinese patent announcement number CN214023171U discloses a continuous die lower die waste blanking device, including a workbench, a lower die support plate fixed on the workbench, and an upper die arranged above the lower die support plate, a waste cavity is arranged inside the lower die support plate, a blanking port connected to the waste cavity is opened on the top plate of the lower die support plate, a funnel is slidably arranged inside the waste cavity, a discharge pipe is arranged at the bottom end of the funnel, and a waste collection box is slidably arranged below the discharge pipe, wherein a first guide device for sliding the funnel is arranged between the funnel and the waste cavity. The utility model can collect the waste falling into the waste cavity through the funnel arranged inside the waste cavity, so that the waste inside the funnel is shaken off to the waste collection box below, and it is no longer necessary to frequently stop the machine to clean up the waste accumulated in the waste cavity, thereby saving the time of the staff to clean up the waste and improving the production efficiency.

[0004] The above-mentioned related technology has the following defects: when the worker opens the box door and manually cleans the waste in the waste collection box, the waste generated by the parts processing continues to fall into the waste collection box through the funnel. This part of the fallen waste may fall out of the waste collection box from the box door due to its own movement inertia, affecting the centralized collection and treatment of the waste, and the edges of the waste are relatively sharp, which may accidentally injure the surrounding workers; in addition, when the worker closes the box door, the waste that continues to fall may be stuck between the box door and the waste collection box, affecting the normal closing of the box door. At this time, in order to close the box door normally and ensure the personal safety of the workers, the continuous mold needs to be shut down, which will still affect the processing efficiency of the parts, so it needs to be improved. Summary of the invention

[0005] In order to solve the above problems, the embodiment of the present application provides a continuous die for processing a slide retainer of an automobile seat, which does not require frequent shutdowns for cleaning of waste materials, thereby improving the processing efficiency of parts.

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0020] See also Figure 1-8 The present application discloses a continuous die for processing a slideway retainer of an automobile seat. Figure 1 and Figure 2 As shown, a continuous die for processing a slide retainer of an automobile seat includes a bracket 1, on which a cylinder 11 and a lower die 13 are mounted, the piston rod of the cylinder 11 extends in a vertical direction and is connected to an upper die 12, the upper die 12 is located directly above the lower die 13, and the lower die 13 is provided with a plurality of blanking openings 131.

[0021] During the processing of the automobile seat slide retainer, the conveyor will convey the metal plate to between the upper die 12 and the lower die 13, and the cylinder 11 will drive the upper die 12 to cyclically rise and fall. The upper die 12 and the lower die 13 cooperate with each other to realize the forming of the retainer; at the same time, the waste material that is punched and dropped by the upper die 12 will fall downward into the blanking port 131.

[0022] The bracket 1 is provided with a plurality of guide hoppers 2, which correspond to the material drop openings 131 one by one. The upper openings of the guide hoppers 2 are flared and located directly below the material drop openings 131, and a collection box 3 is provided directly below the lower openings of the guide hoppers 2.

[0023] The waste in the drop opening 131 will fall downward into the guide hopper 2 , and the guide hopper 2 will gather the waste so that the waste can fall downward accurately into the collection box 3 , and the required size of the collection box 3 is reduced.

[0024] like Figure 2 , Figure 3 and Figure 7 As shown, a seesaw 4 is rotatably connected to the bracket 1 via a horizontal axis 41, a counterweight 42 is installed at one end of the seesaw 4, the collection box 3 is located on the other end of the seesaw 4, and the horizontal axis 41 is located between the counterweight 42 and the collection box 3; a discharge port 31 is provided at one end of the collection box 3 away from the counterweight 42, an opening and closing door 32 is rotatably connected in the discharge port 31, and the opening and closing door 32 and the collection box 3 are connected to the same torsion spring 33; a support platform 5 is provided directly below one end of the seesaw 4 with the counterweight 42.

[0025] When the collection box 3 just starts to collect waste, the weight of the waste in the collection box 3 will be less than the first preset value, and the counterweight block 42 will press one end of the seesaw 4 against the support platform 5 due to its own gravity. At this time, the seesaw 4 will be in a horizontal state, so that the collection box 3 can collect the waste in the guide hopper 2. At the same time, when the torsion spring 33 is in a natural state, the opening and closing door 32 will be closed at the discharge port 31 to prevent the waste in the collection box 3 from leaking out through the discharge port 31.

[0026] like Figure 2 and Figure 4 As shown, a first groove 43 is provided on the lower surface of one end of the seesaw 4 where the counterweight 42 is not provided, a first iron block 44 is fixedly embedded in the first groove 43, and a first magnetic plate 14 is provided directly below the end of the seesaw 4, and the first magnetic plate 14 is installed on the bracket 1; a collection box 6 is provided obliquely below the collection box 3.

[0027] When the collection box 3 contains a large amount of waste, making the weight of the waste greater than the second preset value, the collection box 3 will flip downward to an inclined state due to its own gravity. At this time, the waste in the collection box 3 will slide to the lower end of the collection box 3 due to its own gravity, and the opening and closing door 32 will be pushed open by the waste sliding downward, so that the waste in the collection box 3 can be automatically discharged into the collection box 6.

[0028] When the waste is discharged from the collection box 3, the seesaw 4 will be pressed downward against the first magnetic plate 14, and the first magnetic plate 14 will adsorb and fix the first iron block 44, so that the seesaw 4 and the collection box 3 continue to remain in an inclined state, so that the waste in the collection box 3 can be discharged into the collection box 6 as much as possible.

[0029] When the waste in the collection box 3 is about to be emptied, the counterweight 42 will cause the seesaw 4 to flip and return to a horizontal state due to its own gravity, the first iron block 44 will detach from the first magnetic plate 14, and the opening and closing door 32 will re-close at the discharge port 31, so that the collection box 3 continues to receive the waste dropped from the guide hopper 2. This part of the waste will not fall into the collection box 6 temporarily, so that the workers have enough time to process the waste in the collection box 6.

[0030] like Figure 2 and Figure 3As shown, the bracket 1 is provided with a second magnetic plate 15 located at the first magnetic plate 14, and a second groove 34 is provided on the side of the opening and closing door 32 away from the counterweight block 42, and a second iron block 35 is fixedly embedded in the second groove 34. When the first magnetic plate 14 adsorbs and fixes the first iron block 44, the waste in the collection box 3 will push the opening and closing door 32 to flip open, and at this time, the second magnetic plate 15 will adsorb and fix the second iron block 35, so that the opening and closing door 32 is continuously kept in the open state, so that the waste in the collection box 3 can be quickly discharged through the discharge port 31, and the collection box 3 will be able to flip and reset faster; and the processing speed of the upper mold 12 and the lower mold 13 on the metal plate remains unchanged, so the workers will have more time to process the waste in the collection box 6.

[0031] like Figure 4 As shown, two guide rails 45 are installed on the upper surface of the seesaw 4. The guide rails 45 extend along the axial direction of the horizontal axis 41. The material collecting box 3 is slidably matched with the two guide rails 45, thereby realizing the sliding connection between the material collecting box 3 and the seesaw 4.

[0032] like Figure 5 and Figure 6 As shown, both ends of the upper mold 12 are connected to a rack 17 through a connecting rod 16, the rack 17 is vertically arranged and meshed with a matching gear 181, the matching gear 181 is rotatably connected to the bracket 1 through a first rotating shaft 18, and a first bevel gear 182 is coaxially connected to the first rotating shaft 18; the bracket 1 is rotatably connected to two second bevel gears 191 through a second rotating shaft 19, the second bevel gears 191 correspond to the first bevel gear 182 one by one and mesh with each other, and a cam 192 is coaxially connected to the second rotating shaft 19, and the two cams 192 are respectively arranged on the left and right sides of the collection box 3.

[0033] During the process of the upper mold 12 processing and forming the retaining frame, the upper mold 12 will continuously perform lifting and lowering movements. During the movement, the upper mold 12 will drive the rack 17 to move through the connecting rod 16, and the rack 17 will drive the matching gear 181 to rotate. The matching gear 181 will drive the first bevel gear 182 to rotate through the first rotating shaft 18, and the first bevel gear 182 will drive the second bevel gear 191 to rotate. The second bevel gear 191 will drive the cam 192 to rotate through the second rotating shaft 19. The two cams 192 will push the collection box 3 to shake left and right, so that the waste falling into the collection box 3 can be laid more flatly in the collection box 3. Therefore, the collection box 3 will be able to accommodate more waste at one time, reducing the frequency of unloading the collection box 3, so that the workers have more time to deal with the waste in the collection box 6, and it is not easy for the waste to fall out of the collection box 3 due to excessive accumulation in the same place.

[0034] like Figure 2As shown, a plurality of vertically arranged levers 36 are installed on the inner bottom wall of the material collecting box 3, and the levers 36 correspond to the material guiding hopper 2 one by one, and the upper ends of the levers 36 are penetrated through the inner side of the material guiding hopper 2 and extend into the upper end opening of the material guiding hopper 2. When the material collecting box 3 is shaken left and right, the material collecting box 3 will shake the waste in the material guiding hopper 2 through the levers 36, so that the waste is not easy to block the material guiding hopper 2, ensuring that the waste can normally pass through the material guiding hopper 2 and fall into the material collecting box 3.

[0035] like Figure 5 As shown, all the guide hoppers 2 are connected to the same connecting plate 21, and the connecting plate 21 is connected to the bracket 1 through a plurality of vertically arranged first springs 22; a pressing plate 161 is installed on the connecting rod 16. During the movement of the upper mold 12, the upper mold 12 will drive the pressing plate 161 to intermittently press down the connecting plate 21 through the connecting rod 16, and the first spring 22 will continuously switch between the deformed state and the natural state, so that the guide hopper 2 continuously vibrates up and down, further preventing the waste from clogging the guide hopper 2.

[0036] like Figure 7 and Figure 8 As shown, a slide groove 37 is provided on the upper end surface of the collection box 3, and a plug plate 38 is slidably embedded in the slide groove 37 along the vertical direction; a slot 321 is provided on the upper surface of the opening and closing door 32 for the plug plate 38 to slide and insert, and when the plug plate 38 is inserted into the slide groove 37 and the slot 321 at the same time, the opening and closing door 32 will be inserted and fixed in the discharge port 31, so that the opening and closing door 32 can be stably closed in the discharge port 31, thereby preventing the waste in the collection box 3 from pushing open the opening and closing door 32 during the shaking of the collection box 3.

[0037] It is worth mentioning that the lower end of the opening and closing door 32 is rotatably connected to the collection box 3 via the horizontal axis 323. When the waste in the collection box 3 pushes the opening and closing door 32 to open, the upper end of the opening and closing door 32 will flip downward, so that the opening and closing door 32 can serve as an inclined material guide plate, so that the waste in the collection box 3 can accurately fall into the collection box 6.

[0038] A push rod 381 is installed on the plug plate 38, and the push rod 381 is connected to the collection box 3 through the second spring 382. When the collection box 3 is in a horizontal state, the second spring 382 will be in a natural state, and the plug plate 38 will be inserted into the slot 321, so that the opening and closing door 32 is inserted and fixed, ensuring the closing effect of the opening and closing door 32 on the discharge port 31.

[0039] When the waste in the collection box 3 is discharged, the seesaw 4 will be pressed downward against the first magnetic plate 14, and the upper surface of the first magnetic plate 14 will push the push rod 381 upward, and the push rod 381 will drive the plug plate 38 to rise and disengage from the slot 321. At this time, the opening and closing door 32 will no longer be plugged in and fixed, and the waste in the collection box 3 will push the opening and closing door 32 to open automatically due to its own gravity, so that the waste in the collection box 3 can be quickly discharged.

[0040] The upper end of the opening and closing door 32 is provided with a guide surface 322 inclined toward the inside of the collection box 3. When the waste in the collection box 3 is about to be emptied, the seesaw 4 and the collection box 3 will gradually flip and reset to a horizontal state, and the second spring 382 will prompt the plug plate 38 to descend and reset, and the plug plate 38 will be inserted into the slide groove 37, and the torsion spring 33 will also return to a natural state. At this time, the guide surface 322 of the opening and closing door 32 will push the plug plate 38 to rise until the plug plate 38 moves to just above the slot 321; then the second spring 382 will return to its natural state, so that the plug plate 38 is inserted into the slide groove 37 and the slot 321 at the same time, thereby realizing the automatic insertion and fixation of the opening and closing door 32.

[0041] The working principle of the present application is as follows: during the use of the continuous die, the conveyor will convey the metal plate between the upper die 12 and the lower die 13, the cylinder 11 will drive the upper die 12 to cyclically rise and fall, and the upper die 12 and the lower die 13 will cooperate with each other to realize the forming of the retaining frame; at the same time, the waste material that is punched and dropped by the upper die 12 will fall into the guide hopper 2 through the drop port 131, and the guide hopper 2 will gather the waste material so that the waste material falls accurately into the collection box 3.

[0042] When the collection box 3 just starts to collect waste, the weight of the waste in the collection box 3 will be less than the first preset value, and the counterweight block 42 will press one end of the seesaw 4 against the support platform 5 due to its own gravity. At this time, the seesaw 4 will be in a horizontal state, so that the collection box 3 can collect the waste in the guide hopper 2. At the same time, when the torsion spring 33 is in a natural state, the opening and closing door 32 will be closed at the discharge port 31 to prevent the waste in the collection box 3 from leaking out through the discharge port 31.

[0043] During the cyclic lifting process, the upper mold 12 will drive the pressure plate 161 and the rack 17 to move through the connecting rod 16, the pressure plate 161 will intermittently press the connecting plate 21 downward, and the first spring 22 will continuously switch between the deformed state and the natural state, so that the guide hopper 2 will continuously vibrate up and down to prevent the waste from clogging the guide hopper 2; the rack 17 will drive the matching gear 181 to rotate, the matching gear 181 will drive the first bevel gear 182 to rotate through the first rotating shaft 18, the first bevel gear 182 will drive the second bevel gear 191 to rotate, the second bevel gear 191 will drive the cam 192 to rotate through the second rotating shaft 19, and the two cams 192 will push the collection box 3 to shake left and right, so that the waste falling into the collection box 3 can be spread more evenly in the collection box 3, and the collection box 3 will shake the waste in the guide hopper 2 through the lever 36, further making it difficult for the waste to clog the guide hopper 2.

[0044] When the collection box 3 contains a large amount of waste, making the weight of the waste greater than the second preset value, the collection box 3 will flip downward to a tilted state due to its own gravity until one end of the seesaw 4 is pressed against the first magnetic plate 14. At this time, the first magnetic plate 14 will adsorb and fix the first iron block 44 and push the push rod 381 upward, and the collection box 3 will remain stably in the tilted state. The push rod 381 will drive the plug plate 38 to rise and disengage from the slot 321. The waste in the collection box 3 will slide down due to its own gravity and push the opening and closing door 32 until the second magnetic plate 15 adsorbs and fixes the second iron block 35. The opening and closing door 32 will remain stably in the open state, so that the waste in the collection box 3 can be quickly discharged into the collection box 6.

[0045] When the waste in the collection box 3 is about to be emptied, the counterweight 42 will cause the rocker 4 to flip and return to a horizontal state due to its own gravity, and the torsion spring 33 will cause the opening and closing door 32 to re-close at the discharge port 31, so that the collection box 3 continues to receive the waste dropped from the guide hopper 2. This part of the waste will not fall into the collection box 6 temporarily, so that the workers have enough time to deal with the waste in the collection box 6.

[0046] In summary, the present application can gather the waste materials through the guide hopper 2 and guide them into the collection box 3. The collection box 3 can temporarily store the waste materials and automatically complete the emptying and resetting operations according to the weight of the waste materials, so that workers have enough time to process the waste materials in the collection box 6 without the need for frequent shutdowns to clean the waste materials, thereby improving the processing efficiency of parts.
