Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field related to metal stamping, more particularly to a washing machine bottom flange forming equipment. BACKGROUND

[0002] The washing machine bottom flange forming equipment is a device for processing thick metal into a flange structure by stamping. It uses hydraulic structure as power, drives the upper die to move down, cooperates with the bottom die structure, and completes the stamping and shaping of the flange structure after multiple moving stamping.

[0003] The patent document with publication number CN118595299B records an automatic flange stamping equipment, relating to the technical field of flange production, including: a table body, a chute is opened at the top of the table body, the chute is a "mouth" shaped structure, a plurality of die assemblies are slidably arranged in the chute; a first power assembly is arranged at the top of the table body, and the first power assembly is used to drive the plurality of die assemblies to move circularly in the chute; two first supports are arranged at the two sides of the top of the table body. In the use process, the first power assembly drives the plurality of die assemblies to move circularly in the chute on the table body, so that the die assemblies move to below the first punch, below the third punch and below the second punch in turn, and the punching of the circular plate, the punching of the fixing hole and the punching of the annular structure are performed correspondingly. Therefore, the equipment can independently perform all stamping work of flange production.

[0004] The above-mentioned equipment has certain deficiencies in the forming and processing operation of the washing machine bottom flange. The washing machine bottom flange is made of thick material punched, and the thick metal material is formed after the metal material is cut into a block. The end edge of the cut metal material will produce a curling phenomenon. The curling structure makes the metal thick material unable to be inserted into the limiting groove of the stamping device, so that the metal material is easy to be stuck during feeding operation. Secondly, the washing machine bottom flange is processed and shaped by stamping. When the upper die presses the metal material, the lower die structure completes the stamping and shaping of the washing machine bottom flange. The bottom of the metal material will produce burr curling phenomenon under the influence of the upper die stamping. Artificial polishing is needed for the burr structure on the surface of the flange, which reduces the processing efficiency and has single function. At the same time, the traditional equipment does not have an auxiliary ejection structure, so that the washing machine bottom flange is easy to be stuck in the die structure during stamping operation, which affects the continuous stamping operation of the washing machine bottom flange. SUMMARY

[0005] The purpose of the present application is to provide a washing machine bottom flange forming equipment which can solve the existing problems.

[0006] The problem solved by the present application is:

[0007] 1. The bottom flange of the washing machine is made of thick material stamping. After the rolled metal material is cut into block metal material, the cutting edge of the cut metal material will have a rolled edge phenomenon. The rolled edge structure makes it impossible for the metal material to be inserted into the limiting groove of the stamping device, which makes it easy for the metal material to get stuck during the feeding operation.

[0008] 2. Secondly, the bottom flange of the washing machine is shaped by stamping. When the upper die presses down on the metal material, it works with the lower die structure to complete the stamping and shaping of the bottom flange of the washing machine. During stamping, the bottom of the metal material will produce burrs and curling due to the influence of the upper die. It is necessary to manually grind the burrs on the flange surface, which reduces its processing efficiency and limits its functionality.

[0009] 3. At the same time, traditional equipment does not have an auxiliary ejector structure, which makes it easy for the bottom flange of the washing machine to get stuck in the mold structure during the stamping operation, affecting the continuous stamping operation of the bottom flange of the washing machine.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] A washing machine bottom flange forming device includes a fixed base and a hydraulic top seat. The hydraulic top seat is fixedly installed above the fixed base. Several sets of lower mold bodies are arranged at the middle of the upper end of the fixed base. A telescopic bracket is movably installed at the middle of the lower end of the hydraulic top seat, and several sets of upper mold bodies are arranged at the bottom of the telescopic bracket. A first cutter is installed at the lower part of one end of the telescopic bracket, and a second cutter is installed at the lower part of the other end of the telescopic bracket. A lower cutter is arranged below both the first and second cutters. Grinding rollers are arranged at the upper end of the fixed base between the several sets of lower mold bodies. The lower part of the grinding roller is movably connected to the fixed base through a hydraulic top rod. The lower cutters are movably installed at the inner sides of both ends of the fixed base.

[0012] As a further technical solution of the present invention, the first cutter and the hydraulic top seat, as well as the second cutter and the hydraulic top seat, are all fixed together by splicing brackets. The middle parts of the first cutter and the second cutter are driven by lifting screws. The ends of the cut metal plate will have rolled edges. When performing the bottom flange stamping and shaping operation of the washing machine, the first cutter can be used to cut off the ends of the metal plate, so that the trimmed metal plate can be accurately inserted between the two sets of limiting brackets. The lifting screws enable the first cutter and the second cutter to have telescopic adjustment structures. The first cutter and the second cutter can be extended downwards during use. After the first cutter is used, the lifting screws are rotated, and the threaded structure drives the first cutter upwards, so that the first cutter is retracted into the interior of the splicing bracket, avoiding the first cutter from contacting the subsequently moving metal plate.

[0013] As a further technical scheme of the present application, one side of the first cutter and the second cutter is provided with a limiting clamping groove, one side of the splicing clamping seat is provided with a transverse push buckle matched with the limiting clamping groove, the lower end of the lower cutter is driven by a lower jack rod, and when the metal thick plate cutting process is performed, the lower cutter is driven upward by the lower jack rod, so that the lower cutter provides upward pressure on the metal thick plate, and the first cutter and the second cutter cooperate with the lower cutter to complete the cutting process of the metal thick plate. Compared with the downward cutting of the first cutter and the second cutter, the lower cutter can balance the pressure on the metal thick plate, so that the cut of the metal thick plate is located in the middle position, avoiding the downward rolling edge phenomenon of the first cutter and the second cutter when cutting the metal thick plate. When the first cutter and the second cutter are extended downward, the transverse push buckle is pushed, so that the transverse push buckle is inserted into the limiting clamping groove, thereby reinforcing the first cutter and the second cutter in the extended state and improving the stability thereof during use.

[0014] As a further technical scheme of the present application, the upper end of the fixed base is fixedly installed with a material discharging seat matched with the first cutter, and the inner side of the material discharging seat is movably installed with a side rotary cover plate. The lower end of the material discharging seat is fixedly installed with a slide way. The material discharging seat can be used to discharge the end roll structure of the metal thick plate cut by the first cutter when the side rotary cover plate is opened, so that the cut waste is discharged downward through the slide way.

[0015] As a further technical scheme of the present application, the lower part of the polishing roller is provided with a limiting guide rod on both sides of the hydraulic jack rod, and the two sides of the polishing roller are provided with a positioning clamping seat for fixing the metal thick plate. After the lower die body and the upper die body complete the stamping and shaping of the flange structure, the polishing roller can polish the burr and the rolled edge structure at the lower end of the slot of the metal thick plate during movement, so that the surface of the stamped metal thick plate remains smooth.

[0016] As a further technical scheme of the present application, the positioning clamping seat is in an L-shaped structure, and two groups of guide wheels are movably installed on the inner side of the positioning clamping seat. When the polishing roller polishes the lower part of the metal thick plate, the positioning clamping seat can assist in fixing the two sides of the metal thick plate, so that downward pressure is applied to the metal thick plate, thereby improving the polishing effect of the polishing roller on the metal thick plate.

[0017] As a further technical scheme of the present application, a transverse push rod is fixedly installed at the middle position of one end of the positioning clamping seat, the transverse push rod is movably sleeved on the inner side of the splicing sleeve, and the splicing sleeve and the fixed base are spliced and fixed through a clamping groove. The user can move the transverse push rod in the splicing sleeve by pushing the transverse push rod according to the width of the metal thick plate, drive the positioning clamping seat through the transverse push rod, adjust the distance between the two groups of positioning clamping seats, and clamp the two groups of positioning clamping seats on the two sides of the metal thick plate.

[0018] As a further technical scheme of the present application, the telescopic clamping seat and the hydraulic top seat are driven through a hydraulic rod, the inner side of the telescopic clamping seat is elastically mounted with a plurality of groups of elastic top rods, one end of the elastic top rod penetrates the upper die body, when the upper die body completes the stamping operation of the metal thick plate, the elastic top rod is pushed out downward under the action of the spring when the upper die body moves, thereby pushing out the material clamped in the upper die body.

[0019] As a further technical scheme of the present application, the lower end of the fixed base is fixedly mounted with a fixed bottom plate, the inside of the fixed base is provided with a discharge groove, and the side of the fixed base is fixedly mounted with a discharge nozzle, so that the waste after punching can be discharged outward by cooperation of the discharge groove and the discharge nozzle.

[0020] As a further technical scheme of the present application, the upper part positions of both ends of the fixed base are provided with material conveying frames, one end of the fixed base is arranged in an inclined manner, two groups of rolling rods are movably mounted in the material conveying frames, the metal thick plate is passed through between the two groups of rolling rods in the material conveying frames, and the two groups of rolling rods are driven by a motor in cooperation with a gear.

[0021] The present application has the following beneficial effects:

[0022] 1. By setting the first cutter and the lower cutter, the cutting of the thick material end can be completed during the conveying operation when the washing machine bottom flange forming equipment is used, so that the end roll structure is removed, and the stability during material conveying is improved.

[0023] When in operation, the end of the cut metal thick plate will have a curling phenomenon. When the washing machine bottom flange stamping and shaping operation is performed, the first cutter can be used to cut the end of the metal thick plate, so that the trimmed metal thick plate can be accurately inserted between the two sets of limiting clamping seats. The setting of the lifting screw rod enables the first cutter and the second cutter to have a telescopic adjustment structure, which can be extended downward during use. After the use of the first cutter is completed, the first cutter is driven upward by the screw structure through the rotation of the lifting screw rod, so that the first cutter is retracted into the inside of the splicing clamping seat, avoiding the contact of the first cutter with the subsequent moving metal thick plate, so that the first cutter only cuts the end of the metal thick plate. The setting of the lower cutter improves the use effect of the first cutter and the second cutter. When cutting the metal thick plate, the lower ram drives the lower cutter to move upward, so that the lower cutter provides an upward pressure to the metal thick plate, and the first cutter and the second cutter cooperate with the lower cutter to complete the cutting of the metal thick plate. Compared with the downward cutting of the first cutter and the second cutter, the lower cutter can balance the pressure received by the metal thick plate, so that the cut of the metal thick plate is located at the middle position, avoiding the downward curling phenomenon of the first cutter and the second cutter when cutting the metal thick plate. After the first cutter and the second cutter are extended downward, the horizontal push buckle is pushed, so that the horizontal push buckle is inserted into the limiting clamping groove, thereby reinforcing the first cutter and the second cutter in the extended state and improving the stability thereof during use. The second cutter is mainly used for cutting the finished material. The second cutter can be used to cut the punched metal thick plate, facilitating subsequent transfer.

[0024] 2. By setting the grinding roller, the trimming operation of the burr at the cut position of the washing machine bottom flange forming equipment can be completed simultaneously during use, improving the processing efficiency of the washing machine bottom flange.

[0025] When in use, after the lower die body and the upper die body complete the stamping and shaping of the flange structure, the grinding roller can be used to grind the burr and curling structure at the lower end of the slot of the metal thick plate during movement, so that the surface of the punched metal thick plate remains smooth. When the lower part of the metal thick plate is ground by the grinding roller, the positioning clamping seat can be used to fix the two sides of the metal thick plate, so that a downward pressure is applied to the metal thick plate, thereby improving the grinding effect of the grinding roller on the metal thick plate. According to the width of the metal thick plate, the horizontal push rod is pushed to move within the splicing sleeve, and the positioning clamping seat is driven by the horizontal push rod, so as to adjust the distance between the two sets of positioning clamping seats. The two sets of positioning clamping seats are clamped on both sides of the metal thick plate. The grinding roller is driven to rotate by the motor and the gear, completing the grinding and trimming of the flange structure. Meanwhile, the grinding roller can be driven to move up and down by the hydraulic jack, adjusting the grinding depth.

[0026] 3. By setting the elastic top rod, when the washing machine bottom flange forming equipment is used, the elastic top rod is used to optimize the use of the upper die body, avoiding the phenomenon of material jamming during stamping of the flange structure;

[0027] When the upper die body completes the stamping operation of the metal thick plate, the elastic top rod is pushed out downward under the action of the spring when the upper die body moves upward, thereby pushing out the material jammed in the upper die body. The elastic top rod is elastically connected between the spring and the telescopic clamp seat, so that the elastic top rod has an independent ejection structure, and when the upper die body moves upward, the ejection operation is automatically completed. In addition, the opening side rotary cover plate can use the ejection seat to perform the ejection operation on the end roll material structure of the metal thick plate cut by the first cutter, so that the cut waste is ejected downward through the slide, improving the use effect of the first cutter.

[0038] In order to solve the problem of material end curling, as shown in Figure 2 The first cutter 10 and the hydraulic top seat 9 and the second cutter 7 and the hydraulic top seat 9 are fixedly connected through a splicing clamping seat 16, the middle part of the first cutter 10 and the second cutter 7 is driven by a lifting screw 15, the end of the cut metal plate 22 will have a curling phenomenon, when the laundry machine bottom flange is punched and shaped, the first cutter 10 can be used to cut the end of the metal plate 22, so that the trimmed metal plate 22 can be accurately inserted between the two groups of limiting clamping seats 4, and the lifting screw 15 is provided to make the first cutter 10 and the second cutter 7 have telescopic adjustment structure, which can be used to extend downward, when the first cutter 10 is used, the lifting screw 15 is rotated to drive the first cutter 10 to move upward, so that the first cutter 10 is retracted into the splicing clamping seat 16, avoiding the first cutter 10 from contacting the subsequent moving metal plate 22.

[0039] As shown in Figure 2As shown, one side of the first cutter 10 and the second cutter 7 is provided with a limiting clamping groove 14, one side of the splicing clamping seat 16 is provided with a transverse push buckle 17 matched with the limiting clamping groove 14, the lower end of the lower cutter 12 is driven by the lower jack 13, when the metal thick plate 22 is cut, the lower cutter 12 is driven by the lower jack 13 to move upwards, so that the lower cutter 12 provides upward pressure to the metal thick plate 22, so that the first cutter 10 and the second cutter 7 cooperate with the lower cutter 12 to complete the cutting of the metal thick plate 22, compared with the downward cutting of the first cutter 10 and the second cutter 7, the lower cutter 12 can balance the pressure of the metal thick plate 22, so that the cut of the metal thick plate 22 is located in the middle position, avoiding the downward edge curling phenomenon of the first cutter 10 and the second cutter 7 when cutting the metal thick plate 22, when the first cutter 10 and the second cutter 7 are extended downwards, the transverse push buckle 17 is pushed, so that the transverse push buckle 17 is inserted into the limiting clamping groove 14, thereby reinforcing the first cutter 10 and the second cutter 7 in the extended state, improving the stability thereof during use.

[0040] As shown in the figure, Figure 3 The upper end of the fixed base 1 is fixedly installed with a discharging seat 18 matched with the first cutter 10, the inner side of the discharging seat 18 is movably installed with a side rotary cover plate 19, and the lower end of the discharging seat 18 is fixedly installed with a slide 20. The discharging seat 18 can discharge the end curl structure of the metal thick plate 22 cut by the first cutter 10, so that the cut waste is discharged downward through the slide 20.

[0041] In order to solve the problem of burr after the flange of the washing machine bottom is punched, as shown in the figure, Figure 4 The lower part of the polishing roller 2 is provided with a limiting guide rod 23 on both sides of the hydraulic jack 24, and the two sides of the polishing roller 2 are provided with a positioning clamping seat 21 for fixing the metal thick plate 22. After the lower die body 6 and the upper die body 26 complete the punching and shaping of the flange structure, the polishing roller 2 can polish the burr and curl structure at the lower end of the slot of the metal thick plate 22 when the metal thick plate 22 moves, so that the surface of the punched metal thick plate 22 is smooth.

[0042] As shown in the figure, Figure 5 The positioning clamping seat 21 is in L-shaped structure, and two groups of guide wheels 29 are movably installed on the inner side of the positioning clamping seat 21. When the polishing roller 2 polishes the lower metal of the metal thick plate 22, the positioning clamping seat 21 can assist in fixing the two sides of the metal thick plate 22, so that downward pressure is applied to the metal thick plate 22, thereby improving the polishing effect of the polishing roller 2 on the metal thick plate 22.

[0043] As shown in the figure, Figure 5As shown, the middle of one end of the positioning holder 21 is fixedly installed with a transverse push rod 25, the transverse push rod 25 is movably sleeved on the inner side of the splicing sleeve 30, the splicing sleeve 30 and the fixed base 1 are spliced and fixed through the clamping groove, and the user can adjust the distance between the two groups of positioning holders 21 by pushing the transverse push rod 25 to move the transverse push rod 25 in the splicing sleeve 30, driving the positioning holder 21 through the transverse push rod 25, so that the two groups of positioning holders 21 are clamped on both sides of the metal thick plate 22.

[0044] As shown in the figure, Figure 6 The elastic top rod 28 is installed on the inner side of the telescopic holder 8, one end of the elastic top rod 28 penetrates the upper die body 26, when the upper die body 26 completes the stamping operation of the metal thick plate 22, the elastic top rod 28 is pushed out downward under the action of the spring when the upper die body 26 moves, so as to push out the material clamped in the upper die body 26.

[0045] The lower end of the fixed base 1 is fixedly installed with a fixed bottom plate 5, the inside of the fixed base 1 is provided with a discharge groove, and the side of the fixed base 1 is fixedly provided with a discharge nozzle 3. The waste after punching can be discharged outward by using the discharge groove in cooperation with the discharge nozzle 3.

[0046] The upper part of both ends of the fixed base 1 is provided with a material conveying frame 11, one end of the fixed base 1 is inclined, two groups of rolling rods are movably installed in the material conveying frame 11, the metal thick plate 22 is inserted between the two groups of rolling rods in the material conveying frame 11, and the two groups of rolling rods are driven by a motor in cooperation with a gear.

[0047] When in use, the thick material is punched from the thick material, and the thick material is cut into blocks after being cut into a roll shape. The end of the cut metal thick material has a curled edge phenomenon. The curled structure makes the metal thick material unable to be inserted into the limiting groove of the punching device, so that the metal material is easy to be clamped during the feeding operation.

[0048] Therefore, by setting the first cutter 10 and the lower cutter 12, the cutting of the end of the thick material can be completed during the feeding operation when the washing machine bottom flange forming equipment is used, so as to remove the end curling structure of the material and improve the stability of the material conveying;

[0049] In operation, the cut metal thick plate 22 has a curled end, and the first cutter 10 can cut the end of the metal thick plate 22 when the bottom flange of the washing machine is punched and shaped, so that the trimmed metal thick plate 22 can be accurately inserted between the two sets of limiting clamping seats 4. The lifting screw 15 is provided to make the first cutter 10 and the second cutter 7 have a telescopic adjustment structure, which can be extended downward when in use. After the first cutter 10 is used, the lifting screw 15 is rotated to drive the first cutter 10 to move upward, so that the first cutter 10 is retracted into the splicing clamping seat 16, avoiding contact with the subsequent moving metal thick plate 22, so that the first cutter 10 only cuts the end of the metal thick plate 22. The lower cutter 12 improves the use effect of the first cutter 10 and the second cutter 7. When cutting the metal thick plate 22, the lower cutter 12 is driven upward by the lower top rod 13 to provide upward pressure on the metal thick plate 22, so that the first cutter 10 and the second cutter 7 cooperate with the lower cutter 12 to complete the cutting of the metal thick plate 22. Compared with the downward cutting of the first cutter 10 and the second cutter 7, the lower cutter 12 can balance the pressure on the metal thick plate 22, so that the cut of the metal thick plate 22 is located in the middle position, avoiding the downward curling phenomenon of the first cutter 10 and the second cutter 7 when cutting the metal thick plate 22. When the first cutter 10 and the second cutter 7 are extended downward, the horizontal push buckle 17 is pushed to insert into the limiting clamping groove 14, thereby reinforcing the first cutter 10 and the second cutter 7 in the extended state, improving the stability thereof in use. The second cutter 7 is mainly used for cutting the finished material, and the second cutter 7 can cut the punched metal thick plate 22, facilitating subsequent transfer.

[0050] Secondly, the bottom flange of the washing machine is processed and shaped by punching, and the upper die presses the metal material to complete the punching and shaping of the bottom flange of the washing machine. When punching, the bottom of the metal material will be curled and the surface burr structure of the flange needs to be polished manually, which reduces the processing efficiency and has single function.

[0051] Therefore, by providing the polishing roller 2, the trimming operation of the burr at the cut position of the bottom flange of the washing machine can be completed simultaneously when the bottom flange of the washing machine is formed, thereby improving the processing efficiency of the bottom flange of the washing machine.

[0052] When in use, after the lower die body 6 and the upper die body 26 complete the stamping and shaping of the flange structure, the burrs at the notched lower end of the metal thick plate 22 and the edge curl structure can be polished when the metal thick plate 22 moves, so that the surface of the stamped metal thick plate 22 is smooth. When the lower part of the metal thick plate 22 is polished by the polishing roller 2, the positioning clamping seat 21 can be used to assist in fixing the two sides of the metal thick plate 22, so that a downward pressure is applied to the metal thick plate 22, thereby improving the polishing effect of the polishing roller 2 on the metal thick plate 22. According to the width of the metal thick plate 22, the transverse push rod 25 is pushed to move in the splicing sleeve 30, the positioning clamping seat 21 is driven by the transverse push rod 25, thereby adjusting the distance between the two positioning clamping seats 21, so that the two positioning clamping seats 21 are clamped on the two sides of the metal thick plate 22. The polishing roller 2 is driven to rotate by the motor and the gear, the polishing and finishing of the flange structure are completed, and the polishing depth can be adjusted by driving the polishing roller 2 to move up and down by the hydraulic jack 24.

[0053] Meanwhile, the traditional equipment does not have an auxiliary ejection structure, so that the flange at the bottom of the washing machine is easily stuck in the die structure during stamping, affecting the continuous stamping operation of the flange at the bottom of the washing machine.

[0054] Therefore, the elastic ejector rod 28 is arranged to optimize the use of the upper die body 26 during the use of the flange forming equipment at the bottom of the washing machine, so as to avoid the material from being stuck during stamping.

[0055] When the upper die body 26 completes the stamping operation of the metal thick plate 22, the elastic ejector rod 28 is ejected downward under the action of the spring when the upper die body 26 moves upward, thereby ejecting the material stuck in the upper die body 26. The elastic ejector rod 28 is elastically connected between the spring and the telescopic clamping seat 8, so that the elastic ejector rod 28 has an independent ejection structure and automatically completes the ejection operation when the upper die body 26 moves upward. In addition, the opening side rotary cover plate 19 can perform the ejection operation on the end curl structure of the metal thick plate 22 cut by the first cutter 10 by using the ejection seat 18, so that the cut waste is ejected downward through the chute 20, thereby improving the use effect of the first cutter 10.

[0056] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present application, and any equivalent embodiments with equivalent changes and modifications made on the basis of the technical essence of the present application to the above embodiments are still within the scope of the technical solution of the present application.
