[0002] A sheet metal drilling device is a specialized piece of equipment used for drilling holes in sheet metal parts. It can be adjusted and customized according to different processing requirements to ensure the dimensional accuracy and surface quality of the holes, thereby meeting the needs of the sheet metal parts in subsequent processing or assembly.

[0003] Patent document CN217799151U discloses a drilling machine for sheet metal processing, comprising: a frame on which sheet metal parts are fixed; and a blocking module disposed on the frame, the blocking module comprising an upper cover, a lower cover, a first driving member, and a second driving member, the lower cover being located directly below the upper cover, the upper cover having a first opening, a first suction hole, and a through hole, the lower cover having a second opening and a second suction hole, the through hole being located directly above the first opening; the first driving member is used to drive the upper cover to move upward or downward.

[0004] The above solution seals the processing area with an upper and lower cover and absorbs the metal shavings generated during processing, thereby avoiding waste of resources and pollution of the production environment. However, without a cooling device, the high temperature generated by the drill bit when it rubs against the sheet metal at high speed is difficult to dissipate, which increases the risk of thermal deformation of the drill bit and sheet metal, reduces the service life of the drill bit and the yield of sheet metal processing.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-head sheet metal drilling device.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-head sheet metal drilling device, comprising a multi-head drilling machine and a drilling platform, wherein the drilling platform comprises a first guide section, a drilling section and a second guide section, the first guide section is inclined downward along the direction close to the drilling section, the second guide section is inclined downward along the direction away from the drilling section, a guide plate is rotatably connected above the first guide section, a water supply pipe is provided above the guide plate, a recovery chamber is provided below the drilling platform, the recovery chamber comprises a storage chamber and a liquid supply chamber separated by a partition, a filter plate is provided at the top of the partition, and the bottom of the liquid supply chamber is connected to the water supply pipe through a water pump.

[0008] The present invention is further configured such that: the punching part is horizontally arranged below the multi-head punching machine, and the punching part has a through groove communicating with the liquid supply chamber.

[0009] The present invention is further configured such that: the perforated part is provided with a plurality of connecting holes around the through groove, and a positioning block or a sealing plug is detachably connected in the connecting holes.

[0010] The present invention is further configured such that: the guide plate has guide grooves on both sides, the guide grooves are located above the connection between the guide part and the perforated part, and a fastening nut is provided at one end of the rotating shaft of the guide plate.

[0011] The present invention is further configured such that: the end of the flow guide part away from the perforation part is located above the storage chamber, and the width of the partition is lower than the depth of the storage chamber and the liquid supply chamber.

[0012] The present invention is further configured such that: the filter plate is inclinedly arranged below the through groove in the direction close to the guide plate; the height of the end of the guide section away from the perforated part is lower than the height of the top of the filter plate; and a plurality of water outlet holes are arrayed at the bottom of the water supply pipe located above the guide plate.

[0013] The present invention is further configured such that: a drain pipe is connected to the bottom of the storage chamber, a liquid supply pipe is connected to the top of the liquid supply chamber, a cleaning groove is provided at the bottom of the storage chamber, and a sealing plate is snapped into the cleaning groove.

[0014] In summary, this utility model has the following beneficial effects: the guide plate can guide the liquid flowing out of the water pipe to fall onto the drilling point of the sheet metal part, thereby achieving the effects of cooling and lubrication, which helps to discharge the debris generated during drilling from the hole and improves the service life of the drill bit.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example: A multi-head sheet metal drilling device, such as Figure 1 , Figure 2 and Figure 4 As shown, the machine includes a multi-head drilling machine 1 and a drilling platform 2. The multi-head drilling machine 1 can perform multiple drilling operations on sheet metal parts simultaneously, improving processing efficiency. The drilling platform 2 includes a guide section 1 3, a drilling section 4, and a guide section 2 5. The drilling section 4 is horizontally positioned below the multi-head drilling machine 1. The drilling section 4 has a square through slot 14, which provides the required travel distance for the drill bit of the multi-head drilling machine 1 to penetrate the sheet metal part. The drilling section 4 has several connecting holes 15 around the through slot 14. The inner wall of each connecting hole 15 is provided with internal threads. According to the shape of the sheet metal part, a suitable positioning block 16 is selected and threaded into the connecting hole 15 to fix the sheet metal part, thereby limiting the displacement of the sheet metal part during the drilling process.

[0022] like Figures 1-3 As shown, the first guide section 3 and the second guide section 5 are located on both sides of the drilling section 4. A guide plate 6 is rotatably connected above the first guide section 3. A water pipe 7 is provided above the guide plate 6. Several water outlet holes 20 are arrayed at the bottom of the water pipe 7 located above the guide plate 6. The water pipe 7 carries liquid with an oil content of 20%-30%, which has good lubricity, rust prevention and cooling properties. A fastening nut 19 is provided at one end of the rotating shaft of the guide plate 6. The fastening nut 19 can limit the guide plate 6, so that the guide plate 6 is tilted downward in the direction close to the drilling section 4. By setting the tilt angle of the guide plate 6, the liquid flowing out of the water pipe 7 can be guided to fall onto the drilling point of the sheet metal part, thereby achieving the effect of cooling and lubrication. It helps to discharge the debris generated during drilling from the hole, reduces the risk of thermal deformation of the drill bit and sheet metal part, and thus improves the service life of the drill bit and the yield of sheet metal part processing.

[0023] like Figures 1-4 As shown, a sealing plug 17 is fitted into each of the several connecting holes 15 of the connecting positioning block 16, thereby sealing the connecting holes 15 and preventing liquid from leaking out of the connecting holes 15. The first guide section 3 is inclined downwards towards the drilling section 4, and the second guide section 5 is inclined downwards away from the drilling section 4. A recovery chamber 8 is located below the drilling platform 2. The recovery chamber 8 includes a storage chamber 10 and a liquid supply chamber 11 separated by a partition 9. The second guide section 5 is located away from the drilling section 4. One end is located above the storage chamber 10, so that the debris generated during drilling of the sheet metal parts will slide down the inclined surface of the guide section 2 5 into the storage chamber 10 along with the push of the water flow. The guide plate 6 has guide grooves 18 on both sides. The guide grooves 18 are located above the connection between the guide section 1 3 and the drilling section 4, so that some of the liquid on the guide plate 6 will flow out from the guide grooves 18 on both sides to the connection between the guide section 1 3 and the drilling section 4, thereby preventing the debris generated during drilling from accumulating at the connection between the guide section 1 3 and the drilling section 4.

[0024] like Figures 1-3 As shown, the width of the partition 9 is lower than the depth of the storage chamber 10 and the supply chamber 11. A filter plate 12 is provided on the top of the partition 9. The height of the end of the guide section 5 away from the perforation section 4 is lower than the height of the top of the filter plate 12. The filter plate 12 allows liquid to pass through while blocking debris from passing through. When the liquid accumulated in the storage chamber 10 is higher than the top of the partition 9, it will flow through the filter plate 12 into the supply chamber 11. The filter plate 12 is inclined and set below the through groove 14 in the direction close to the guide plate 6. The through groove 14 is located above the supply chamber 11, so that the debris and liquid generated by the drill bit of the multi-head drilling machine 1 when penetrating the sheet metal part will fall onto the filter plate 12. At this time, the liquid will fall into the supply chamber 11 through the filter plate 12, and the debris will slide into the storage chamber 10 due to the inclined surface of the filter plate 12.

[0025] like Figures 1-4 As shown, the bottom of the liquid supply chamber 11 is connected to the water supply pipe 7 via a water pump 13. The water pump 13 can draw the liquid collected in the liquid supply chamber 11 and transport it back to the guide plate 6 through the water supply pipe, thereby achieving the effect of liquid recycling and reuse, reducing resource waste. A cleaning groove 23 is provided at the bottom of the storage chamber 10. A sealing plate 24 is snapped into the cleaning groove 23. A movable handle is fixedly connected to the end of the sealing plate 24 away from the water pump 13. Sealing strips are provided on the other peripheral walls of the sealing plate 24 except for the fixed movable handle. The sealing plug 17 and the sealing strip are both made of rubber material, which has good deformation, waterproof and sealing properties, so that when the sealing plate 24 is snapped into the cleaning groove 23 and the sealing plug 17 is snapped into the connection hole 15, there is a good sealing effect.

[0026] like Figure 1 and Figure 2As shown, a drain pipe 21 is connected to the bottom of the storage chamber 10. The end of the drain pipe 21 away from the storage chamber 10 is connected to a waste liquid treatment device via a water pump 13. When it is necessary to clean up the debris accumulated in the storage chamber 10, the liquid in the storage chamber 10 is first emptied through the water pump 13 and the drain pipe 21. Then, the handle is pulled to pull the sealing plate 24 out of the cleaning tank 23. At this time, the storage chamber 10 can be opened to remove the debris accumulated inside. A liquid supply pipe 22 is connected to the top of the liquid supply chamber 11. The end of the liquid supply pipe 22 away from the liquid supply chamber 11 is connected to a water storage tank via the water pump 13. The water storage tank stores a pre-mixed liquid. When the liquid in the liquid supply chamber 11 is insufficient, the liquid in the water storage tank can be drawn by the water pump 13 and transported to the liquid supply chamber 11 through the liquid supply pipe 22.

[0027] Working principle: The inclined guide plate 6 guides the liquid flowing from the water pipe 7 to the drilling point of the sheet metal part. The debris generated during drilling will slide down the inclined surface of the guide section 5 into the storage chamber 10 under the thrust of the water flow. The debris and liquid generated by the drill bit of the multi-head drilling machine 1 when penetrating the sheet metal part will fall onto the filter plate 12. At this time, the liquid will fall into the supply chamber 11 through the filter plate 12, and the debris will slide down the inclined surface of the filter plate 12 into the storage chamber 10. When the storage chamber 10 accumulates... When the liquid level is higher than the top of the partition 9, it will flow through the filter plate 12 into the liquid supply chamber 11. The water pump 13 can draw the liquid from the liquid supply chamber 11 and transport it back to the guide plate 6 through the water pipe 7, thus recycling the liquid. The drain pipe 21 is used to drain the liquid in the storage chamber 10. Pulling the handle to pull the sealing plate 24 out of the cleaning tank 23 will open the storage chamber 10, at which time the debris accumulated inside the storage chamber 10 can be removed. The liquid supply pipe 22 is used to replenish the liquid supply chamber 11 with sufficient liquid.
