Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 9, the present invention provides a trimming structure of a stamping die for an automobile door panel, comprising an upper die 100, a lower die 200, and a die 300, wherein the die 300 is fixedly installed at the bottom of the upper die 100,
A bonding detector 400 disposed on the lower die 200 for detecting the bonding degree between the plate and the die,
A tilt head 500 disposed in the lower mold 200 for lifting up the plate to correct the posture;
The die head 300 comprises a first cutter head 301, a second cutter head 302 and a third cutter head 303, the cutter head height of the second cutter head 302 is lowest relative to the first cutter head 301 and the third cutter head 303, and the height of the first cutter head 301 is highest relative to the second cutter head 302 and the third cutter head 303.
After the fitting posture of the plate to be processed, the die cavity and the core is standard, the first tool bit 301, the second tool bit 302 and the third tool bit 303 on the die head 300 are respectively cut at different positions to avoid the stress difference of the materials, so that the defect of cutting deformation of the materials is prevented.
As shown in fig. 2, the vertical projections of the first cutter head 301 and the third cutter head 303 are two arcs or straight lines which are co-peaked and symmetrical with respect to the second cutter head 302, and the second cutter head 302 is a middle line of the vertical projections of the first cutter head 301 and the third cutter head 303.
The first cutter head 301, the second cutter head 302 and the third cutter head 303 are arranged to be not flush and mainly used for adjusting the cutter setting sequence, the notch to be cut is cut off from the middle by utilizing the second cutter head 302 to be longitudinally cut from the middle, different areas of stress possibly existing in the material are cut off, and the material is cut off from the areas with the same stress on the two sides through the first cutter head 301 and the third cutter head 303 respectively, so that deformation of a plate is prevented.
As shown in fig. 5, 7 and 8, the fit detector 400 includes a probe outer cylinder 401, the tip end face of the probe outer cylinder 401 is parallel to the cavity and core surface of the lower die 200,
A probe pin 402, both ends of which are conducted and located inside the probe outer cylinder 401,
A needle 403 fixedly connected to the top end of the probe needle 402 and sealed at the joint with the needle 402, the needle 403 is slidingly sleeved inside the probe outer cylinder 401,
A piston 408, the piston 408 being in fixed communication with the bottom end of the probe pin 402,
A negative pressure tube 406 fixedly installed in the lower die 200, and the negative pressure tube 406 is in interference fit with the piston 408 and is communicated with the inner cavity of the probe needle 402 through the piston 408,
And a barometer 407, which is disposed in the cavity of the negative pressure pipe 406 and is used for detecting the air pressure in the negative pressure pipe 406.
When the plate covers the cylinder hole 4011 of the outer probe cylinder 401, the air in the probe needle core 402 and the needle head 403 can be rapidly emptied by connecting the negative pressure pipe 406 with an external vacuum pump, and the air in the closed cavity formed by the needle head 403, the plate body and the outer probe cylinder 401 can be discharged. Because the outer surface under the needle 403 is provided with the multi-layer sealing ring 4033 and the inner wall of the probe outer cylinder 401 form an interference fit state, the pressure at the bottom of the needle 403 will be greater than the pressure in the closed cavity, so that the probe needle core 402 and the needle 403 are pushed upwards until the closed cavity is closed. The closed needle 403 will automatically close the bore 4011 of the outer probe cylinder 401 to prevent irregular machining marks from being left on the surface of the plate due to the existence of the bore 4011 in subsequent stamping when the standard of the fitting posture of the plate and the cavity core is detected.
As shown in fig. 8, the fit detector 400 further includes a cylinder hole 4011 provided at the top end of the probe outer cylinder 401,
A needle 403, which is fixedly connected to the tip of the probe core 402,
The axis of the needle 403 is provided with a first needle hole 4031 which is penetrated, the middle step of the needle 403 is provided with a second needle hole 4032 along the direction parallel to the axis, and the first needle hole 4031 and the second needle hole 4032 are communicated with the probe needle core 402.
The position of the barrel hole 4011 is flush with the top of the core, if the plate placed on the lower die 200 is in an accurate posture, the surface of the plate can be attached to the barrel hole 4011, when the barrel hole 4011 is in a negative pressure state, air inlet blockage can occur at the position of the barrel hole 4011, and then the pressure in the barrel hole 4011 and a cavity communicated with the barrel hole 4011 can be kept. The cylindrical hole 4011 is communicated with the probe needle core 402 and the cavity in the negative pressure tube 406 downwards, so that an accurate pressure result can be obtained through the barometer 407. The bore 4011 communicates with the probe core 402 through a first needle aperture 4031 and a second needle aperture 4032 on the needle 403. The first needle hole 4031 is used to continue to conduct space when the tip of the needle 403 enters the cavity above the bore 4011, thereby allowing the needle 403 and the bore 4011 to be closed completely by negative pressure.
As shown in fig. 6, the tip of the probe outer cylinder 401 is disposed at the intersection of the cavity and the core in the mold, and when the needle 403 and the cylinder hole 4011 overlap, the tip of the needle 403 is parallel to the surfaces of the core and the cavity.
The probe outer cylinder 401 is parallel to the cavity and core surfaces on the lower die 200, and is mainly used for detecting and not damaging the cavity surfaces, and preventing the plate surface from being irregularly shaped into dents or convex marks during stamping. The main purpose of locating the probe outer barrel 401 at the intersection of the cavity and core is that the only angle of refraction on the plate can be fully engaged therewith, if the plate can be engaged tightly with the probe outer barrel 401, its position and attitude will be accurate, if not, it will be the opposite. If the probe outer cylinder 401 is arranged at a flat position, the situation of wrong surface fitting may still result in inaccurate detection results. Therefore, the arrangement of the probe outer cylinder 401 at the intersection of the cavity and the core can be used to eliminate small probability errors and improve accuracy.
As shown in fig. 7, a spring seat 4012 is provided at the bottom end of the outer probe cylinder 401, a first top block 404 is fixedly sleeved on the probe core 402, and the first top block 404 and the spring seat 4012 are elastically supported by a spring 405.
The spring 405 is used to assist in returning the probe core 402 and needle 403 downward when the pressure returns to normal, i.e., when the plate is removed from the mold. When the probe needle core 402 and the needle 403 are upwards under negative pressure, the top cylinder hole 4011 of the probe outer cylinder 401 is upwards sealed against the elastic force of the spring 405, and the spring 405 is used for forming a pressure threshold value, so that whether the cylinder hole 4011 on the probe outer cylinder 401 is reliably sealed or not can be accurately judged. If the spring 405 is not provided here as an obstacle for the probe core 402 and the needle 403 to go upward, the small gap left when the plate is not fully attached can still form a negative pressure environment in the cylindrical hole 4011 to make it upward, so that a defect that the detection result is inaccurate may be caused, and therefore, the provision of the spring 405 can be used to improve the detection accuracy.
As shown in fig. 3 and 4, the lower die 200 includes a hydraulic rod 201, a first top plate 202 and a second top plate 203, wherein an output end of the hydraulic rod 201 is connected to a bottom of the first top plate 202 for pushing the first top plate 202 upward;
the first top plate 202 pushes the second top plate 203 upward through the main push rod 204 and the auxiliary push rod 205 arranged on the first top plate, and the second top plate 203 is used for driving the inclined top 500 to correct the plate posture.
The hydraulic rod 201 is used for controlling the first top plate 202 and the second top plate 203 to lift, and the auxiliary ejector rod 205 is used for assisting in pushing the second top plate 203.
As shown in fig. 3 and 4, the first top block 404 can pass through the second top plate 203 through a rectangular hole formed in the second top plate 203, two first sliding blocks 207 are slidably installed at the bottom of the second top plate 203, an inclined top block 206 is fixedly connected to the top end of the main top rod 204, and the inclined surface of the inclined top block 206 is attached to the inclined surface of the first sliding block 207 so as to push the two first sliding blocks 207 to close when the inclined top block 206 goes up, thereby supporting the bottom of the first top block 404 above the second top plate 203.
The main ejector rod 204 and the inclined ejector block 206 move upwards through the first top plate 202 and simultaneously move upwards, the inclined ejector block 206 and the first sliding block 207 are matched to push the first sliding blocks 207 to fold towards the middle, when the first ejector block 404 passes through the rectangular groove and is positioned above the second top plate 203, the first sliding blocks 207 are positioned at the bottom of the second top plate 203 to support the bottom of the first ejector block 404, the sealing effect of the needle 403 is improved, the needle 403 is pushed downwards by partial deformation of the plate positioned at the hole part of the outer probe cylinder 401 in the forming process, and the flatness of the surface of the plate is ensured. When the first top block 404 does not pass through the rectangular slot to reach above the second top plate 203, the first two sliding blocks 207 present a clamping state to the first top block 404 to continuously push the second top plate 203 upwards.
As shown in fig. 3, 4 and 9, the oblique top 500 includes a second slider 501, a top block 502 and a rod body 503, the second slider 501 and the top block 502 are connected through the rod body 503, the second slider 501 is movably hinged with the rod body 503, and the top block 502 can be accommodated in the lower die 200 and kept parallel to the surface of the cavity or the core;
the second slider 501 is slidably mounted on the top surface of the second top plate 203.
During the upward pushing of the pitched roof 500 by the second top plate 203, there is a displacement of the bottom of the second slider 501 in the horizontal direction, where the displacement can be compensated for by the removal of the sliding position on the second top plate 203. The movable hinge connection method between the second slider 501 and the rod body 503 is also used for forming rotation in the angle direction so as to compensate the angle change during sliding. After the top block 502 stretches out, the plate is pushed to separate from the cavity of the die to slightly fluctuate, so that the cavity is prevented from buckling inwards, and the gravity center of the plate is automatically adjusted to return to the center line of the two dies. After completion, the top block 502 is lowered to carry the plate back to the cavity. The pushing position of the top block 502 is displaced at the smooth position of the plate, so that the junction of the inner buckle or the die cavity and the core is avoided, and the defect of adjustment failure caused by hooking is avoided.
The working principle and the using flow of the invention are as follows:
Through setting up the different sword orders of first tool bit 301, second tool bit 302 and third tool bit 303, utilize second tool bit 302 to cut off the different regions of material stress, rethread first tool bit 301 and third tool bit 303 respectively cut off the material in the same region of both sides stress to prevent that the plate from appearing warping.
The lamination posture between the plate and the die is detected by the lamination detector 400, when the cylindrical hole 4011 on the outer probe cylinder 401 is covered with the material in a lamination manner, a negative pressure area is formed after the gas in the cylindrical hole 4011 is exhausted, and whether the material is properly laminated can be judged by detecting the pressure of the area. If the fitting is accurate, after the top block 502 is stretched out, the plate is pushed to separate from the cavity of the die to slightly fluctuate, so that the cavity is prevented from buckling inwards, and the gravity center of the die is automatically adjusted to return to the center line of the two dies. After completion, the top block 502 is lowered to carry the plate back to the cavity.
