Description

Technical Field

[0001] The invention belongs to the field of stamping dies, and in particular relates to a square beveled die which is convenient for demoulding. Background Art

[0002] With the development of industrial technology, modern stamping die technology has become more and more perfect. If you need to stamp multiple wavy grooves on sheet metal materials, you need to put the sheet metal into the stamping die. Each time the stamping die is stamped, the sheet metal needs to be pushed forward a unit distance for the next stamping, which is very wasteful of manpower.

[0003] As disclosed in Patent No. 202211181037.X, a stamping die for automobile sheet metal that is easy to demold includes a base plate, a lower die seat and a guide column are fixedly connected to the upper end of the base plate, a mounting plate is fixedly connected to the upper end of the guide column, a hydraulic telescopic rod is fixedly connected to the upper end of the mounting plate, the output end of the hydraulic telescopic rod passes through the mounting plate, and the output end of the hydraulic telescopic rod is fixedly connected to the upper punch die; a lifting mechanism is provided in the lower die seat, a movable plate and a lifting plate are slidably connected in the lower die seat, a fixed seat is fixedly connected to the lower end of the movable plate, a support rod is rotatably connected in the fixed seat, a connecting column is slidably connected in the movable plate, one end of the connecting column is fixedly connected to the lifting plate, the other end of the connecting column is fixedly connected to the connecting plate, a first spring is fixedly connected to the upper end of the connecting plate, and the upper end of the first spring is fixedly connected to the movable plate. The present invention improves work efficiency by allowing the stamped automobile sheet metal in the lower die seat to be separated from the lower die seat under the action of the lifting plate;

[0004] The device still has defects when in use. First, the device can only punch one groove shape at a time. If it is necessary to punch many shapes on the sheet metal material, the sheet metal needs to be positioned in multiple stamping dies for stamping. Second, when the sheet metal is transported, it is easy to generate distortion force on the sheet metal, thereby forming stress depression. This stress depression needs to be reset by tapping. Relatively small stress depressions are not easy to be observed, and thus cannot be reset by manual tapping. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies in the prior art and provide a square bevel mold that is easy to demold. When the device is in use, the winding motor drives the sheet metal material to stop after advancing a unit distance through the winding roller. At this time, the hydraulic press drives the movable die seat to fall down.

Five linear array movable mold bases 7 are arranged below, and an insertion hole is arranged in the middle of the movable mold base 7. Two extended beams 701 are connected in series inside the insertion hole. The movable mold base 7 in the middle position and the two extended beams 701 are locked by pressing bolts, and the movable mold base 7 in the middle position is installed on the output rod of the hydraulic press 301. An expansion elastic mechanism is arranged between the movable mold bases 7, and a feeding assembly is arranged between the movable mold base 7 and the loading platform 6; a stress oscillation mechanism is arranged on one side of the base plate 5.

[0030] In this embodiment, the hydraulic press 301 drives the movable die base 7 to fall down, and when the movable die base 7 and the bottom die base 6 are merged, a groove will be pressed out of the sheet metal between the movable die base 7 and the bottom die base 6. In the process of forming the grooves on the sheet metal material, the distance between the five groups of movable die bases 7 and the bottom die base 6 will also change. Compared with the sheet metal stamping dies in the prior art, the sheet metal between two stamping grooves on the sheet metal will be elongated. If the two stamping grooves are relatively large, the sheet metal between the two stamping grooves will be over-elongated or even torn. In the process of forming the five stamping grooves of the device, the distance between the five stamping dies can also be changed accordingly to prevent the sheet metal from being torn.

[0031] In a further embodiment of the present invention, Figure 1-3 As shown, the material feeding component includes a sheet metal twist 1 in the front and rear of the base plate 5, a winding roller 101 is arranged in the middle rotation of the front sheet metal twist 1, and a discharge roller 103 is arranged in the middle rotation of the rear sheet metal twist 1. The winding roller 101 is installed on the output end of the winding motor 102, and the outer side of the discharge roller 103 pulls out the sheet metal material 2 and is connected to the outer wall of the winding roller 101.

[0033] In a further embodiment of the present invention, Figure 1-5 As shown, the female mold assembly includes two bottom mold seats 601 at the top of the stage 6. The bottom mold seats 601 are fixed to the top surface of the stage 6 by countersunk bolts. The material of the bottom mold seats 601 is high-speed steel.

[0034] In this embodiment, the movable die holder 7 is inserted between the two bottom die holders 601 to implement stamping. The staff can reduce or increase the distance between the two bottom die holders 601 according to the stamping requirements, thereby changing the size of the stamping groove.

[0035] In a further embodiment of the present invention, Figure 1-5 As shown, the bottom surface contour of the movable mold base 7 matches the concave cavity between each group of bottom mold bases 601, and a thickened tile can be installed on the bottom surface of the movable mold base 7.

[0036] In this embodiment, while the distance between the two bottom mold bases 601 is reduced and increased, a thickened tile is installed on the bottom surface of the movable mold base 7 to match the bottom mold base 601 .

[0037] In a further embodiment of the present invention, Figure 1-4 As shown, the expansion elastic mechanism includes a pulling spring 702 between the movable mold base 7, and organic oil is applied between the extended beam 701 and the interlaced hole on the movable mold base 7.

[0038] In this embodiment, when the movable mold base 7 is punched downward, all the pulling springs 702 between the movable mold bases 7 will be compressed. When the movable mold base 7 is lifted upward, the movable mold base 7 will expand due to the elastic force of the pulling springs 702 until the elastic force of the pulling springs 702 is completely released.

[0039] In a further embodiment of the present invention, Figure 1-5 As shown, the positioning elastic force component includes a cross bar on the side wall of the worktable 6, and a disc 602 is provided at the end of the cross bar. The discs 602 are connected in series through expansion springs 603, and the spacing between the worktables 6 formed by the elastic force of the expansion springs 603 is equal to the spacing between the movable mold seats 7 formed by the elastic force of the pulling springs 702. The movable mold seats 7 correspond one-to-one with each group of bottom mold seats 601 in the vertical direction.

[0040] In this embodiment, when the elastic force of the expansion spring 603 between the loading platforms 6 is completely released, the distance between the loading platform 6 and the bottom mold base 601 at the top thereof will be fully expanded, and can correspond to the loading platform 6 above it.

[0041] In a further embodiment of the present invention, Figure 1-6 As shown, the stress oscillation mechanism includes a fixed oscillation frame 4, an oscillation rod 401 is rotatably arranged in the middle of the oscillation frame 4, a accommodating chamber is arranged on the oscillation rod 401, a bent plate 405 is installed inside each accommodating chamber, and the oscillation rod 401 is installed on the output shaft of the stepping motor 403. The material of the oscillation rod 401 is plastic material, and the structure of the oscillation rod 401 is a thin-walled shell with a thickness of two millimeters.

[0042] In this embodiment, the sheet metal material 2 after stamping will form a wavy state, and then the wavy sheet metal material 2 will be cut into small sections to form bent plates 405, and each section of the bent plate 405 will be placed in the accommodating compartment outside the vibration rod 401. The stepper motor 403 drives the vibration rod 401 to quickly twist back and forth thirty degrees. When the wavy sheet metal is vibrated, the stress depression formed on the sheet metal due to the twisting force of transportation will be bounced back and flattened. Compared with the sheet metal stamping device in the prior art, the sheet metal will be subjected to twisting force during transportation, and the twisting force will form stress depression on the surface of the sheet metal, and the contour of the finished sheet metal will be deformed.

[0043] In a further embodiment of the present invention, Figure 1-6 As shown, the accommodating chamber includes a loading slot 404 on the outside of the oscillation frame 4, and a bent plate 405 is loaded inside the loading slot 404. The width of the loading slot 404 is greater than the thickness of the bent plate 405 by five millimeters, and steel sheets with a thickness of one millimeter can be added to the two side walls of the loading slot 404. A sealing mechanism is provided on the outside of the loading slot 404.

[0044] In this embodiment, the bent plate 405 is placed inside the filling slot 404. The gap of the filling slot 404 is larger than the wavy sheet metal, which can allow the wavy sheet metal to oscillate inside the filling slot 404. Adding a steel sheet inside the filling slot 404 can reduce the gap between the filling slot 404 and the wavy sheet metal.

[0045] In a further embodiment of the present invention, Figure 1-6 As shown, the blocking mechanism includes end plates 402 at both ends of the oscillation rod 401, an axial hole matching the output shaft of the stepper motor 403 is arranged in the middle of the end plate 402, and a shielding tile mechanism is arranged on the outer side of the filling slot 404.

[0046] In this embodiment, the end plate 402 blocks the front and rear ports of the filling slot 404 to prevent the bent plate 405 from falling out of the front and rear ports of the filling slot 404 .

[0047] In a further embodiment of the present invention, Figure 1-6 As shown, the shielding tile mechanism includes a locking tile 406 at the end of the filling slot 404, magnet bars are arranged on both sides of the locking tile 406, and an iron sheet matching the magnet bars is arranged at the end of the filling slot 404.

[0048] In this embodiment, before the bent plate 405 is disassembled, the locking shoe 406 is first removed, and the locking shoe 406 is pulled outward until the iron sheet is free from the attraction of the magnet strip on the inner wall of the locking shoe 406 .

[0049] Working principle: The hydraulic press 301 drives the movable die seat 7 to fall down. When the movable die seat 7 and the bottom die seat 6 are merged, a groove will be pressed out of the sheet metal between the movable die seat 7 and the bottom die seat 6. In the process of forming the groove on the sheet metal material, the distance between the five sets of movable die seats 7 and the bottom die seat 6 will also change. Compared with the sheet metal stamping dies of the prior art, the sheet metal between the two stamping grooves on the sheet metal will be elongated. If the two stamping grooves are relatively large, the sheet metal between the two stamping grooves will be over-elongated or even torn. In the process of forming the five stamping grooves of the device, the distance between the five stamping dies can also be changed accordingly to avoid the sheet metal from being torn. The winding motor 102 drives the sheet metal material 2 through the winding roller 101. After each advance of a unit of distance, the sheet metal material 2 stops, a wave groove is punched out on the sheet metal material 2, and then rolled up onto the winding roller 101. The movable die seat 7 is inserted between the two bottom die seats 601 to carry out stamping. The staff can reduce or increase the distance between the two bottom die seats 601 according to the stamping requirements, thereby changing the size of the stamping groove. While the distance between the two bottom die seats 601 is reduced and increased, a thickened tile is installed on the bottom surface of the movable die seat 7 to match the bottom die seat 601. When the movable die seat 7 is stamped downward, all the pulling springs 702 between the movable die seats 7 will be compressed. When the movable die seat 7 rises upward, the movable die seat 7 expands through the elastic force of the pulling springs 702 until the pulling springs When the elastic force of the spring 702 is completely released and the elastic force of the expansion spring 603 between the loading platform 6 is completely released, the distance between the loading platform 6 and the bottom mold base 601 on its top will be fully expanded, and can correspond to the loading platform 6 above it. The stamped sheet metal material 2 will form a wavy state, and then the wavy sheet metal material 2 will be cut into small sections to form a bent plate 405, and each section of the bent plate 405 will be placed in the accommodating chamber outside the vibration rod 401. The stepper motor 403 drives the vibration rod 401 to twist back and forth thirty degrees quickly. When the wavy sheet metal is vibrated, the stress depression formed on the sheet metal due to the twisting force of transportation will be bounced back and flattened. Compared with the sheet metal stamping device in the prior art, the sheet metal is recycled during transportation. The bending plate 405 is placed inside the filling slot 404. The gap of the filling slot 404 is larger than the wavy sheet metal, which can allow the wavy sheet metal to vibrate inside the filling slot 404. Adding a steel sheet inside the filling slot 404 can reduce the gap between the filling slot 404 and the wavy sheet metal. The end plate 402 blocks the front and rear ports of the filling slot 404 to prevent the bending plate 405 from falling out of the front and rear ports of the filling slot 404. Before disassembling the bending plate 405, first remove the locking washer 406 and pull the locking washer 406 outward until the iron sheet is free from the attraction of the magnet strip on the inner wall of the locking washer 406.
