[0001] The utility model relates to the technical field of punching for forming washing machine balance weights, and specifically relates to a punching device for forming washing machine balance weights. Background Technique

[0002] When a washing machine washes clothes, it needs to rotate the drum at a high speed. However, due to the difference in the mass of each part of the washing machine drum, washing machine balance weights are often installed on the washing machine drum to make the washing machine in a balanced state during operation.

[0003] At present, when using a punching device for forming washing machine balance weights, most punching devices are fixed in a certain position, and thus can only punch a certain position of the washing machine balance weight, and cannot adjust the washing machine balance weight to a suitable horizontal position with the punching device according to different required punching positions of the washing machine balance weight. Therefore, it will bring great inconvenience to the users during actual use, and at the same time limit the use of this device. For this reason, we propose a punching device for forming washing machine balance weights. Content of the Utility Model

[0016] 1. In the punching device for forming a washing machine balance weight, the output ends of two hydraulic cylinders drive two L-shaped positioning plates to move towards the two ends of the washing machine balance weight, adjust the distance between the two L-shaped positioning plates according to the washing machine balance weight and clamp and fix it.

Then, the drill bit can be separated and disassembled from the second mounting plate through the threaded grooves. Therefore, it is convenient for operators to disassemble and replace the drill bit that has been used for too long, and prevent the phenomenon of low hole opening efficiency caused by the drill bit not being sharp enough and not being replaceable after long-term use.

[0018] 3. For the punching device for forming the balance weight of the washing machine, the dust suction pipe connected to the dust suction pump and the dust suction hood can suck the debris generated by drilling the balance weight of the washing machine in the box body into the processing box for collection. When a certain amount is collected, hold the handle and pull it outwards, driving the door body to rotate outwards synchronously through the hinge to open the processing box, so as to facilitate the operator to automatically collect the debris generated during drilling for subsequent processing work, prevent the debris from accumulating in the box body and splashing everywhere, and thus prevent unnecessary impacts and pollution on the normal drilling work and the surrounding environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, A punching device for forming a washing machine balance weight, comprising a bottom plate 1. Hydraulic telescopic rods 2 are fixedly installed around the top of the bottom plate 1. The top of the output ends of the four hydraulic telescopic rods 2 is provided with a box body 3. Hydraulic cylinders 4 are arranged on both sides of the box body 3. On one side of the output ends of the two hydraulic cylinders 4, L-shaped positioning plates 5 are fixedly installed. Protective pads 6 are fixedly installed on the tops of the two L-shaped positioning plates 5. An electric telescopic rod 7 is arranged on the top of the box body 3. The bottom of the output end of the electric telescopic rod 7 is fixedly installed with a square plate 8. A driving motor 9 is fixedly installed at the bottom of the square plate 8. The bottom of the output shaft of the driving motor 9 is fixedly installed with a first mounting plate 10. A second mounting plate 11 is arranged at the bottom of the first mounting plate 10. A processing box 15 is arranged at the top of the hydraulic telescopic rod 2. Dust extraction pipes 16 are sleeved on both sides of the front of the processing box 15. A door body 19 is arranged on the right side of the processing box 15.

[0026] Further, the output ends of the hydraulic cylinders 4 respectively penetrate through one side of the box body 3 and are fixedly connected to the L-shaped positioning plates 5. The materials of the two protective pads 6 are both rubber materials. Advantage: The output ends of the two hydraulic cylinders 4 drive the two L-shaped positioning plates 5 to move towards both ends of the washing machine balance weight, adjust the distance between the two L-shaped positioning plates 5 according to the washing machine balance weight and clamp and fix it. When the output ends of the two hydraulic cylinders 4 move in the same direction, the washing machine balance weight clamped between the two L-shaped positioning plates 5 can be displaced. At the same time, setting the two L-shaped positioning plates 5 as rubber materials can protect the washing machine balance weight during clamping, preventing the phenomenon of clamping injury to the washing machine balance weight caused by hard contact clamping. Thus, it can automatically perform hole opening work and protective fixing work at different positions on washing machine balance weights with different diameters.

[0027] Further, the bottoms and output ends of the hydraulic telescopic rods 2 are respectively fixedly connected to the top of the bottom plate 1 and the bottom of the box body 3. Advantage: The output ends of the four hydraulic telescopic rods 2 can drive the box body 3 to move up and down, and the height position of the box body 3 can be adjusted arbitrarily. Thus, it can facilitate different users to adjust this device to a suitable height for use according to their own height, so as to facilitate users with different heights to perform hole opening work on the washing machine balance weight of this device.

[0028] Further, threaded grooves 12 are penetrated and opened around the tops of the first mounting plate 10 and the second mounting plate 11. The threaded grooves 12 are grouped in pairs and a total of four groups are provided. The inner cavities of each group of threaded grooves 12 are threadedly connected with fixing screws 13. Advantage: By rotating the four fixing screws 13 counterclockwise in the corresponding four groups of threaded grooves 12 and taking them out, the fixation between the first mounting plate 10 and the second mounting plate 11 is released. Subsequently, the drill bit 14 can be separated and removed through the threaded groove 12 and the second mounting plate 11, so that the operator can conveniently disassemble and replace the drill bit 14 that has been used for too long, and prevent the phenomenon of low hole-opening efficiency caused by the drill bit being not sharp enough and non-replaceable after long-term use.

[0029] Further, the driving motors 9 are fixedly connected to the bottoms of the output ends of the electric telescopic rods 7 through square plates 8. A drill bit 14 is fixedly installed at the bottom of the second mounting plate 11. The bottom of the drill bit 14 is provided in a sharp cone shape. Advantage: The output end of the electric telescopic rod 7 moves up and down to drive the driving motor 9 and the drill bit 14 to move synchronously through the square plate 8, and the position of the drill bit 14 is adjusted to the position in contact with the washing machine balance weight. Subsequently, the output shaft of the driving motor 9 drives the drill bit 14 to rotate and open a hole through the first mounting plate 10 and the second mounting plate 11, so that the user can conveniently open holes in washing machine balance weights of different thicknesses; at the same time, setting the bottom of the drill bit 14 in a sharp cone shape can quickly drill holes in the washing machine balance weight.

[0030] Further, the bottoms of the dust extraction pipes 16 penetrate through the tops of the hydraulic telescopic rods 2 and are sleeved with dust extraction covers 17. Dust extraction pumps 18 are sleeved in the middle of the dust extraction pipes 16.

[0031] Further, the door body 19 is rotatably connected to the processing box 15 through a hinge. A handle 20 is fixedly installed on the right side of the door body 19. Advantage: The dust extraction pipe 16 connected to the dust extraction pump 18 and the dust extraction cover 17 can suck the debris generated by drilling the washing machine balance weight in the box body 3 into the processing box 15 for collection. When a certain amount is collected, hold the handle 20 and pull it outwards, driving the door body 19 to rotate outwards synchronously through the hinge to open the processing box 15, so that the operator can conveniently perform automatic centralized collection of the debris generated during drilling for subsequent processing work, prevent the debris from accumulating in the box body 3 and splashing everywhere, and further prevent unnecessary influence and pollution on the normal drilling work and the surrounding environment.

[0032] Working principle: When in use, first, the output ends of two hydraulic cylinders 4 drive two L-shaped positioning plates 5 to move towards both ends of the washing machine balance weight, adjust the distance between the two L-shaped positioning plates 5 according to the washing machine balance weight and clamp and fix it. When the output ends of the two hydraulic cylinders 4 move in the same direction, the washing machine balance weight clamped between the two L-shaped positioning plates 5 can be displaced. At the same time, the two L-shaped positioning plates 5 are made of rubber material to protect the washing machine balance weight during clamping, preventing the clamping of hard contact from causing damage to the washing machine balance weight. Thus, it can automatically perform opening hole work and protective fixing work at different positions on washing machine balance weights with different diameters. After adjusting the position where the washing machine balance weight needs to be opened to the same level as the drill bit 14 and completing the fixing, at this time, the output end of the electric telescopic rod 7 moves up and down, driving the driving motor 9 and the drill bit 14 to move synchronously through the square plate 8, adjusting the position of the drill bit 14 to the contact position with the washing machine balance weight. Subsequently, the output shaft of the driving motor 9 drives the drill bit 14 to rotate and open a hole through the first mounting plate 10 and the second mounting plate 11, thus facilitating the operator to perform opening hole work on washing machine balance weights with different thicknesses. At the same time, the bottom of the drill bit 14 is set in a sharp cone shape to quickly drill the washing machine balance weight. When opening a hole, the debris generated by drilling the washing machine balance weight in the box body 3 can be pumped into the processing box 15 for collection through the dust suction pipe 16 connected to the dust suction pump 18 and the dust suction hood 17. When a certain amount is collected, hold the handle 20 and pull it outwards, driving the door body 19 to rotate outwards synchronously through the hinge to open the processing box 15, thus facilitating the operator to automatically collect the debris generated during drilling for subsequent processing work, preventing the debris from accumulating in the box body 3 and splashing everywhere, and further preventing unnecessary influence and pollution on the normal drilling work and the surrounding environment. When it is necessary to replace the drill bit 14 with a long service time, the four fixing screws 13 can be rotated counterclockwise in the corresponding four groups of threaded grooves 12 to remove them, releasing the fixation between the first mounting plate 10 and the second mounting plate 11. Subsequently, the drill bit 14 can be separated and disassembled from the second mounting plate 11 through the threaded groove 12, thus facilitating the operator to disassemble and replace the drill bit 14 with a long service time, preventing the poor phenomenon of low opening hole efficiency caused by the drill bit being not sharp enough and not replaceable after long-term use.
