Description

Technical Field

[0002] Automobile doors provide a passage for drivers and passengers to enter and exit the vehicle, isolate external interference, reduce side impacts to a certain extent, and protect passengers. During the production process of automobile doors, cutting devices for cutting automobile door raw materials are often required to ensure the normal production of automobile doors.

[0003] Currently, when cutting automobile door raw materials, they are clamped and then cut by a cutting knife.

Currently, the cutting devices for automobile door raw materials can only perform single cutting and cannot grind and clean the flanging iron chips on the cutting surface after cutting. Workers need to disassemble the cut automobile door raw materials and then refix them on a dedicated grinding device, which increases the working steps of automobile doors and the labor intensity of workers, and reduces the processing efficiency of automobile doors.

A second motor 10 is fixedly connected to the side wall of the L-shaped plate 2, and the movable end of the second motor 10 is fixedly connected to one end of the lead screw 9.

[0040] The clamping mechanism includes two vertical plates 14, which are connected to the upper end of the workbench 1 through a moving mechanism. The upper sides of the two vertical plates 14 close to each other are fixedly connected with a fixing seat 15. The side wall of the fixing seat 15 away from the vertical plate 14 is rotatably connected to a shaped plate 17 through a first rod 16. The inner wall of the shaped plate 17 is slidably connected to a pressing plate 19 (such as Figure 4 shown).

[0041] Both ends of the first rod 16 are fixedly connected to a fixing plate 47. A torsion spring 48 is sleeved on the side wall of the first rod 16 close to the fixing plate 47. One end of the torsion spring 48 is fixedly connected to the side wall of the fixing seat 15, and the other end of the torsion spring 48 is fixedly connected to the side wall of the fixing plate 47 (such as Figure 6 As shown in FIG. 1 , the torsion spring 48 can ensure that the profile plate 17 maintains its initial position when not subjected to external forces, that is, maintains a horizontal position.

[0042] The moving mechanism includes two first grooves 11 formed at the upper end of the workbench 1, and the inner walls of the two first grooves 11 are slidably connected with a Z-shaped plate 13 (such as Figure 4 As shown in the figure, the side wall of the workbench 1 near the first groove 11 is fixedly connected with two second hydraulic cylinders 12, the output ends of the two second hydraulic cylinders 12 are fixedly connected with the side walls of the corresponding Z-shaped plates 13, the upper ends of the two Z-shaped plates 13 close to each other are fixedly connected with the lower ends of the two vertical plates 14, and the side wall of the workbench 1 located between the two first grooves 11 is fixedly connected with a debris collecting frame 49, which can collect the debris generated during cutting and subsequent grinding (such as Figure 3 shown).

[0043] The clamping mechanism also includes two second grooves 20 provided at the lower end of the L-shaped plate 2, the two second grooves 20 corresponding to the two L-shaped plates 17 one by one, the inner wall of the second groove 20 is slidably connected to a second slider 21, the lower end of the second slider 21 is fixedly connected to an arc plate 22, the inner wall of the arc plate 22 is provided with an arc groove 23, the inner wall of the arc groove 23 is slidably connected to a movable plate 18 (such as Figure 3 As shown), the lower end of the movable plate 18 is fixedly connected to the upper end of the corresponding pressing plate 19, and the arc center of the arc groove 23 coincides with the axis center of the first rod 16.

[0044] When the two first hydraulic cylinders 3 are adjusted to contract, the L-shaped plate 2 moves downward, and then the two second sliders 21 drive the two pressing plates 19 to move downward through the two arc-shaped plates 22 and the two movable plates 18 to press the raw material of the automobile door. At this time, the cutting knife 8 moves down to the side wall of the automobile door, and the arc center of the arc groove 23 is arranged to coincide with the axis of the first rod 16, so that when the L-shaped plate 17 rotates along the first rod 16 later, the movable plate 18 can slide synchronously on the inner wall of the arc groove 23. At this time, the arc plate 22 always keeps pressing on the movable plate 18, which will not affect the pressing of the cut automobile door raw material.

[0045] The adjustment mechanism includes a through slot 24 opened on the side wall of the vertical plate 14, two second rectangular rods 25 are fixedly connected between the top and the bottom of the through slot 24, and the side walls of the two second rectangular rods 25 are slidably connected with a first plate 26, and the upper end of the first plate 26 is rotatably connected to the lower end of the adjacent U-shaped plate 17 through a rotating plate 27.

[0046] like Figure 2 - Figure 4 As shown, when the first plate 26 moves upward, the first plate 26 drives the Z-shaped plate 17 to rotate upward through the rotating plate 27, and when the first plate 26 moves downward, the first plate 26 drives the Z-shaped plate 17 to rotate downward through the rotating plate 27, so that the angle of the cut automobile door material can be adjusted, so that the edge of the cut surface of the automobile door material is in contact with the side wall of the cutting knife 8. When the second hydraulic cylinder 12 is extended later, the Z-shaped plate 13 will drive the angle-adjusted automobile door material to approach the side wall of the cutting knife 8 through the vertical plate 14 and the Z-shaped plate 17. At this time, the side wall of the rotating cutting knife 8 cleans the flanging iron filings on the cut surface of the automobile door material, avoiding the need for staff to disassemble the cut automobile door material and then re-fix it on a special grinding device in the prior art, which increases the working steps of the automobile door and the labor of the staff, and reduces the processing efficiency of the automobile door.

[0047] A rotating mechanism is provided on the vertical plate 14, and the rotating mechanism includes a second rod 28 rotatably connected to the side wall of the vertical plate 14, the second rod 28 is fixedly connected to the side wall close to the Z-shaped plate 17 with a disk 29, and the side wall of the disk 29 away from the axis is rotatably connected to the lower end of the first plate 26 through a rotating rod 30, a third groove 31 is opened at the upper end of the Z-shaped plate 13, and the inner wall of the third groove 31 is sealingly and slidably connected to the second plate 32, the lower end of the second plate 32 is elastically connected to the bottom of the third groove 31 through a plurality of first springs 33, the upper end of the second plate 32 is fixedly connected to a toothed plate 34, and the side wall of the second rod 28 away from the disk 29 is fixedly connected to a gear 35 meshing with the toothed plate 34.

[0048] like Figure 4 and Figure 5 As shown, it should be noted that when the shaped plate 17 maintains a horizontal position, the rotating rod 30, the second plate 32 and the toothed plate 34 are all in the initial position. At this time, the connection between the rotating rod 30 and the disk 29 is located in the middle of the side wall of the disk 29. The disk 29 is set at the same time. Then, in the subsequent process of the toothed plate 34 continuously moving upward, the toothed plate 34 can rotate counterclockwise through the gear 35, driving the disk 29 to rotate counterclockwise, so that the rotating rod 30 rotates counterclockwise from the middle position of the side wall of the disk 29 to the side wall position directly below the disk 29, thereby driving the first plate 26 to move up and down.

[0049] An extrusion mechanism is provided at the upper end of the workbench 1, and the extrusion mechanism includes two extrusion frames 37 fixedly connected to the side walls on both sides of the workbench 1. The inner wall of the extrusion frame 37 is sealingly and slidably connected to the third plate 38. The side wall of the third plate 38 is fixedly connected to the side wall of the Z-shaped plate 13 adjacent to it through a fixing rod 39. The lower end of the workbench 1 is fixedly connected to two oil storage tanks 36 corresponding to the two extrusion frames 37, and the oil storage tanks 36 are provided with hydraulic oil.

[0050] like Figure 5 , Figure 7 and Figure 8 As shown, the inner wall of the extrusion frame 37 is connected to the lower inner wall of the oil storage tank 36 through a one-way oil suction pipe 40, the inner wall of the extrusion frame 37 is connected to the lower inner wall of the third groove 31 through a first one-way oil outlet pipe 41, the inner wall of the extrusion frame 37 is connected to the lower inner wall of the oil storage tank 36 through a second one-way oil outlet pipe 42, and the inner wall of the third groove 31 is connected to the upper inner wall of the oil storage tank 36 through a third one-way oil outlet pipe 43.

[0051] The one-way oil suction pipe 40 only allows hydraulic oil to enter the extrusion frame 37 from the oil storage tank 36, the first one-way oil outlet pipe 41 only allows hydraulic oil to enter the third groove 31 from the extrusion frame 37, the second one-way oil outlet pipe 42 only allows hydraulic oil to enter the oil storage tank 36 from the extrusion frame 37, and the third one-way oil outlet pipe 43 only allows hydraulic oil to enter the oil storage tank 36 from the third groove 31.

[0052] like Figure 8 As shown, a first solenoid valve 44 is installed in the first one-way oil outlet pipe 41 , a second solenoid valve 45 is installed in the second one-way oil outlet pipe 42 , and a third solenoid valve 46 is installed in the third one-way oil outlet pipe 43 .

[0053] When the car door material is just cut, it is necessary to adjust the extension and contraction of the two second hydraulic cylinders 12 to adjust the distance between the two Z-shaped plates 17. At this time, the Z-shaped plate 13 drives the third plate 38 to slide through the fixing rod 39. At this time, the first solenoid valve 44 and the third solenoid valve 46 are powered off and closed, and the second solenoid valve 45 is powered on and opened. Then, during the sliding process of the third plate 38, the hydraulic oil in the extrusion frame 37 will circulate in one direction through the one-way oil suction pipe 40 and the second one-way oil outlet pipe 42 in the extrusion frame 37 and the oil storage tank 36, and the hydraulic oil will not enter the third groove 31. At this time, the position of the Z-shaped plate 17 will not change;

[0054] After the automobile door material is cut into two halves, the first solenoid valve 44 is powered on and opened, the second solenoid valve 45 and the third solenoid valve 46 are powered off and closed, and then the two second hydraulic cylinders 12 are adjusted to contract. At this time, the third plate 38 squeezes the hydraulic oil in the extrusion frame 37 into the third groove 31 through the first one-way oil outlet pipe 41, driving the second plate 32 and the tooth plate 34 to move upward. At this time, the gear 35 drives the disc 29 to rotate through the second rod 28. In this process, it rotates at the connection between the rotating rod 30 and the disc 29 to the side wall just above the disc 29 and stops. At this time, the U-shaped plate 17 can be driven to rotate upward, and then the two second hydraulic cylinders 12 are adjusted to extend again, so that the two automobile door materials are close to the side wall of the cutting knife 8, and the flanging iron filings on the cut surface of the automobile door material are cleaned. At this time, the extrusion frame 37 absorbs oil through the one-way oil suction pipe 40 to prepare for subsequent extrusion;

[0055] The above operation is to grind the upper part of the cut surface of the automobile door raw material. When it is necessary to grind the lower part of the cut surface of the automobile door raw material, the two second hydraulic cylinders 12 are adjusted to contract again. At this time, the hydraulic oil in the extrusion frame 37 enters the third groove 31 again, driving the second plate 32 and the tooth plate 34 to move upward. At this time, the gear 35 drives the disc 29 to rotate through the second rod 28. In this process, the connection between the rotating rod 30 and the disc 29 rotates to the side wall just below the disc 29 and stops. At this time, the shaped plate 17 can be driven to rotate downward, and then the two second hydraulic cylinders 12 are adjusted to extend again, so that the two automobile door raw materials are close to the side wall of the cutting knife 8, and the flanging iron filings on the cut surface of the automobile door raw material are cleaned;

[0056] After the grinding is completed, the first solenoid valve 44 is powered off and closed, and the second solenoid valve 45 and the third solenoid valve 46 are powered on and opened. At this time, when the two second hydraulic cylinders 12 shrink, the hydraulic pressure in the extrusion frame 37 will enter the oil storage tank 36 through the second one-way oil outlet pipe 42, and the second plate 32 moves downward under the action of multiple first springs 33, squeezing the hydraulic oil in the third groove 31 into the oil storage tank 36 through the third one-way oil outlet pipe 43, and then the toothed plate 34 drives the gear 35 to rotate in the opposite direction to its original position, so that the disc 29 rotates in the opposite direction to the initial position, driving the shaped plate 17 back to the initial position, which is convenient for the next operation.

[0057] A processing and cutting method for manufacturing automobile doors comprises the following steps:

[0058] S1, adjust the extension and contraction of the two second hydraulic cylinders 12, adjust the distance between the two U-shaped plates 17 to be consistent with the width of the automobile door material, and then place the automobile door material to be cut between the two U-shaped plates 17;

[0059] S2, adjust the two first hydraulic cylinders 3 to contract, drive the L-shaped plate 2 to move downward, at this time, the two arc plates 22 drive the two pressing plates 19 to move downward through the two moving plates 18, and press the automobile door material tightly, at this time, the cutting knife 8 moves down to the side wall of the automobile door material;

[0060] S3, start the first motor 7 to rotate, drive the cutting knife 8 to rotate, and start the second motor 10 to rotate, drive the lead screw 9 to rotate, so that the first slider 5 drives the cutting knife 8 to move through the two connecting plates 6 to cut the raw material of the automobile door;

[0061] S4, then adjust the two second hydraulic cylinders 12 to contract, driving the two cut car door materials to separate, at this time the toothed plate 34 will drive the gear 35 to rotate, adjusting the angle of the profile plate 17 and the cut car door material;

[0062] S5. The two second hydraulic cylinders 12 are adjusted to extend again, so that the side wall of the automobile door material fits with the side wall of the cutting knife 8, and the flanging iron filings on the cut surface of the automobile door material are cleaned.

[0063] When cutting the raw material of the automobile door, firstly, the two second hydraulic cylinders 12 are adjusted to be extended and retracted, so that the two Z-shaped plates 13 drive the two U-shaped plates 17 to move through the two vertical plates 14, the two fixing seats 15 and the two first rods 16, and the distance between the two U-shaped plates 17 is adjusted to be consistent with the width of the raw material of the automobile door, and then the raw material of the automobile door to be cut is placed between the two U-shaped plates 17;

[0064] Then, the two first hydraulic cylinders 3 are adjusted to contract, driving the L-shaped plate 2 to move downward, and then the two second sliders 21 drive the two pressing plates 19 to move downward through the two arc plates 22 and the two moving plates 18 to press the raw material of the automobile door. At this time, the cutting knife 8 moves down to the side wall of the automobile door, and then the first motor 7 is started to rotate, driving the cutting knife 8 to rotate, and at the same time, the second motor 10 is started to rotate, driving the lead screw 9 to rotate, so that the first slider 5 drives the cutting knife 8 to move through the two connecting plates 6 to cut the raw material of the automobile door;

[0065] In the above steps, when the distance between the two Z-shaped plates 17 is adjusted, the Z-shaped plate 13 drives the third plate 38 to slide through the fixing rod 39, and the first solenoid valve 44 and the third solenoid valve 46 are powered off and closed, and the second solenoid valve 45 is powered on and opened. Then, during the sliding process of the third plate 38, the hydraulic oil in the extrusion frame 37 will circulate in one direction in the extrusion frame 37 and the oil storage tank 36 through the one-way oil suction pipe 40 and the second one-way oil outlet pipe 42, and the hydraulic oil will not enter the third groove 31. At this time, the position of the Z-shaped plate 17 will not change;

[0066] After the automobile door raw material is cut into two halves, the first solenoid valve 44 is powered on and opened, the second solenoid valve 45 and the third solenoid valve 46 are powered off and closed, and then the two second hydraulic cylinders 12 are adjusted to contract. At this time, the third plate 38 squeezes the hydraulic oil in the extrusion frame 37 into the third groove 31 through the first one-way oil outlet pipe 41, driving the second plate 32 and the tooth plate 34 to move upward. At this time, the gear 35 drives the disc 29 to rotate through the second rod 28. In this process, it rotates to the side wall just above the disc 29 at the connection between the rotating rod 30 and the disc 29 and stops. At this time, the disc 29 drives the first plate 26 to move upward through the rotating rod 30. When the first plate 26 moves upward, the first plate 26 drives the shaped plate 17 to rotate upward through the rotating plate 27. Then, the two second hydraulic cylinders 12 are adjusted to extend again, so that the two automobile door raw materials are close to the side wall of the cutting knife 8, and the flanging iron filings on the cut surface of the automobile door raw material are cleaned. At this time, the extrusion frame 37 absorbs oil through the one-way oil suction pipe 40 to prepare for subsequent extrusion;

[0067] The above operation is to grind the upper part of the cut surface of the automobile door raw material. When it is necessary to grind the lower part of the cut surface of the automobile door raw material, the two second hydraulic cylinders 12 are adjusted to contract again. At this time, the hydraulic oil in the extrusion frame 37 enters the third groove 31 again, driving the second plate 32 and the tooth plate 34 to move upward. At this time, the gear 35 drives the disc 29 to rotate through the second rod 28. In this process, it rotates to the side wall just below the disc 29 at the connection between the rotating rod 30 and the disc 29 and stops. At this time, the disc 29 drives the first plate 26 to move downward through the rotating rod 30. When the first plate 26 moves downward, the first plate 26 drives the shaped plate 17 to rotate downward through the rotating plate 27. Then, the two second hydraulic cylinders 12 are adjusted to extend again, so that the two automobile door raw materials are close to the side wall of the cutting knife 8, and the flanging iron filings on the cut surface of the automobile door raw material are cleaned, avoiding the need for the staff to disassemble the cut automobile door raw materials and then re-fix them on the special grinding equipment in the prior art, which increases the working steps of the automobile door and the labor of the staff, and reduces the processing efficiency of the automobile door;

[0068] After the grinding is completed, the first solenoid valve 44 is powered off and closed, and the second solenoid valve 45 and the third solenoid valve 46 are powered on and opened. At this time, when the two second hydraulic cylinders 12 shrink, the hydraulic pressure in the extrusion frame 37 will enter the oil storage tank 36 through the second one-way oil outlet pipe 42, and the second plate 32 moves downward under the action of multiple first springs 33, squeezing the hydraulic oil in the third groove 31 into the oil storage tank 36 through the third one-way oil outlet pipe 43, and then the toothed plate 34 drives the gear 35 to rotate in the opposite direction to its original position, so that the disc 29 rotates in the opposite direction to the initial position, driving the shaped plate 17 back to the initial position, which is convenient for the next operation.

[0069] At the same time, the arc center of the arc groove 23 is arranged to coincide with the axis center of the first rod 16, so that when the U-shaped plate 17 rotates along the first rod 16, the movable plate 18 can slide synchronously on the inner wall of the arc groove 23. At this time, the arc plate 22 always keeps pressing on the movable plate 18, which will not affect the pressing of the cut automobile door raw material.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
