Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, and in particular to a combined sheet metal processing equipment. Background Technology

[0002] In metal sheet processing, drilling is frequently required. Existing metal sheet drilling equipment traditionally falls into two categories: large drilling machines used in factories (too bulky for on-site use) and portable drilling machines. Portable drilling machines are convenient to carry and can be used anytime, anywhere, but they are prone to causing deviations in the perpendicularity of the hole's centerline to the aluminum alloy sheet surface. Furthermore, neither type of drilling machine has a polishing device; after drilling, the holes must be manually polished to remove burrs for easier use in later parts. Both drilling methods increase subsequent processing steps for the aluminum alloy sheet, increasing the workload for workers.

[0003] To address the aforementioned issues, invention patent CN112705947A discloses a drilling device for processing aluminum alloy sheets. The device includes a worktable with two first sliding grooves located on opposite sides. A second sliding groove is formed on one side of the worktable at the location of the first sliding grooves. A first limiting member is slidably mounted on one end of the first sliding groove, and a second limiting member is slidably mounted on one end of the second sliding groove. While this solution can polish the burrs formed after drilling, avoiding subsequent polishing processes, reducing labor intensity, and ensuring drilling effectiveness, the overall linkage of the device is insufficient. It cannot guarantee the smooth operation of drilling and polishing in tandem. Furthermore, it does not clean or cool the sheet material during drilling and polishing, posing certain drawbacks for subsequent sheet processing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a combined processing equipment for sheet metal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A combined sheet metal processing equipment includes a frame, a worktable, a base plate, a drilling assembly, a grinding assembly, a transmission assembly, and a cleaning assembly. The drilling assembly consists of a hydraulic push rod and a motor drill, and is used for drilling holes in the sheet metal. The hydraulic push rod is fixedly installed on the side of the worktable by a fixing frame, and the motor drill is fixedly installed on the telescopic end of the hydraulic push rod.

[0007] The grinding assembly consists of a grinding plate, a first motor, a reciprocating screw, and a screw nut, and is used to grind the surface of the plate after drilling. Side plates are fixedly provided on both sides of the worktable. The first motor is fixedly mounted on one side plate. The reciprocating screw is rotatably connected between a pair of side plates and is coaxially fixedly connected to the output shaft of the first motor. The screw nut is threadedly connected to the reciprocating screw and a connecting mechanism is provided between it and the grinding plate.

[0008] The transmission assembly consists of a fixed roller group and a pressure roller group, used to fix and intermittently transmit the plate. The fixed roller group is fixedly installed on the inner wall of the side plate, and the upper end of the pressure roller group is threaded to the upper end of the side plate. The pressure roller group is fully engaged with the fixed roller group. A drive mechanism for intermittently rotating the fixed roller group is installed on the frame.

[0009] The cleaning system consists of a water spray cylinder, a spray head, and a water pump cylinder, used to spray cleaning water onto the surface of the board to clean it. The water spray cylinder is fixed to the upper end of the side plate, and several spray heads are located on the side wall of the water spray cylinder and connected to it. The water pump cylinder is fixedly installed on the frame and connected to the water spray cylinder through a water outlet pipe. A water storage tank is fixedly installed on the base plate, and the water pump cylinder is connected to the water storage tank through a water inlet pipe. A water pumping mechanism is installed on the frame.

[0010] Preferably, the connecting mechanism includes a connecting rod, a spring, and a sleeve. The connecting rod is fixed to the lower end of the lead screw nut, the sleeve is fixed to the upper end of the grinding plate, and the connecting rod is slidably inserted into the sleeve and the spring is elastically connected between the two.

[0011] Preferably, the drive mechanism includes a second motor, a main gear, an incomplete secondary gear, and a first pinion. The second motor is fixedly mounted on the frame. The main gear is coaxially fixedly connected to the output shaft of the second motor. The first pinion is coaxially fixedly connected to a wheel component of a fixed gear set. The incomplete secondary gear is rotatably connected to the frame and intermittently meshes with the first pinion. The main gear and the incomplete secondary gear are connected by a belt pulley.

[0012] Preferably, the outlet pipe is equipped with a one-way valve that allows liquid to flow only from the pump cylinder to the spray cylinder, and the inlet pipe is equipped with a one-way valve that allows liquid to flow only from the storage tank to the pump cylinder.

[0013] Preferably, the pumping mechanism includes a slide rail plate, a slide groove, a slider assembly, and a piston rod. The slide rail plate is fixedly installed on the side plate, the slide groove is formed on the side wall of the slide rail plate, the slider assembly is vertically slidably connected in the slide groove, one end of the piston rod is fixedly connected to the side wall of the slider assembly, and the other end is sealed and slidably connected to the inner wall of the pump cylinder. A pushing mechanism for pushing the slider assembly to slide vertically back and forth is installed on the frame.

[0014] Preferably, the pushing mechanism includes a rotating shaft and a push rod. The rotating shaft is rotatably connected to the frame. One end of the push rod is rotatably connected to the extension of the rotating shaft, and the other end is rotatably connected to the lower end of the sliding assembly via a rotating component. A transmission mechanism for driving the rotating shaft to rotate is installed on the frame.

[0015] Preferably, the transmission mechanism includes a full secondary gear and a second pinion, both of which are rotatably connected to the frame. The full secondary gear is connected to the main gear via a pulley, and the second pinion is coaxially fixedly connected to the rotating shaft and meshes with the full secondary gear.

[0016] Preferably, the upper end of the water storage tank is open, and a filter screen is provided at the upper end of the water storage tank.

[0017] The present invention has the following beneficial effects:

[0018] 1. This invention achieves multi-component collaborative operation, constructing a highly efficient linkage system. After the power source output shaft drives the main gear to rotate, it drives the incomplete secondary gear through belt pulley transmission, causing it to intermittently mesh with the first pinion, thereby controlling the intermittent rotation of the fixed gear group and achieving precise material transfer. On the other hand, it drives the complete secondary gear through belt pulley, which then meshes with the second pinion to drive the rotating shaft to rotate. The rotating shaft pushes the slider assembly to slide back and forth through the push rod, providing power to the water pumping mechanism. This avoids action delays or misalignments caused by independent driving of each component. At the same time, the intermittent transmission characteristics of the transmission component can precisely match the drilling rhythm of the drilling component and the polishing rhythm of the grinding component, allowing seamless connection of drilling, grinding, transmission, cleaning and other processes, greatly improving the smoothness of the overall processing flow, reducing processing interruptions caused by poor component linkage, and improving processing efficiency.

[0019] 2. The cleaning component of this invention can immediately clean and cool the surface of the board after drilling and grinding. The pump cylinder in the cleaning component draws cleaning water from the water storage tank through the water inlet pipe, delivers it to the spray nozzle through the water outlet pipe, and then sprays it evenly onto the surface of the board through several spray heads. On the one hand, the sprayed cleaning water can quickly wash away metal debris and burr powder generated during drilling and grinding, preventing impurities from adhering to the surface of the board and affecting the accuracy of subsequent processing. On the other hand, when the cleaning water comes into contact with the board, it can absorb the heat generated by drilling and grinding, effectively reducing the temperature of the board and preventing deformation of the board due to excessive processing temperature. At the same time, it avoids the impact of high temperature on drilling accuracy and grinding smoothness, ensuring the quality of board processing, reducing rework caused by impurity residue or high temperature deformation, and reducing subsequent processing costs.

[0020] 3. The present invention achieves the recycling of cooling and cleaning water through the design of the cleaning components and the water storage tank. The upper end of the water storage tank is open and equipped with a filter screen. After the cleaning water sprayed from the spray head has finished cleaning and cooling the board, it will naturally fall into the water storage tank. During the falling process, impurities such as metal fragments and powder carried in the cleaning water will be filtered by the filter screen at the top of the water storage tank. The filtered cleaning water is retained in the water storage tank and can be drawn out again by the pump cylinder through the water inlet pipe for reuse in cleaning and cooling the board. This recycling design eliminates the need for frequent replenishment of new cleaning water, greatly reducing water consumption, lowering water costs in the processing process, and reducing wastewater discharge, which is in line with the green and environmentally friendly processing concept.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example 1

[0031] Reference Figure 1-4 A combined sheet metal processing equipment includes a frame 1, a worktable 3, a base plate 4, a drilling assembly, a grinding assembly, and a transmission assembly. The drilling assembly consists of a hydraulic push rod 5 and a motor drill 25, and is used for drilling holes in the sheet metal. The hydraulic push rod 5 is fixedly installed on the side of the worktable 3 by a fixing frame, and the motor drill 25 is fixedly installed on the telescopic end of the hydraulic push rod 5.

[0032] The grinding assembly consists of a grinding plate 30, a first motor 6, a reciprocating screw 7, and a screw nut 26. It is used to grind the surface of the plate after drilling. Side plates 10 are fixedly installed on both sides of the worktable 3. The first motor 6 is fixedly installed on one side plate 10. The reciprocating screw 7 is rotatably connected between a pair of side plates 10 and is coaxially fixedly connected to the output shaft of the first motor 6. The screw nut 26 is threadedly connected to the reciprocating screw 7 and a connecting mechanism is provided between it and the grinding plate 30.

[0033] The connecting mechanism includes a connecting rod 27, a spring 28, and a sleeve 29. The connecting rod 27 is fixed to the lower end of the lead screw nut 26, and the sleeve 29 is fixed to the upper end of the grinding plate 30. The connecting rod 27 is slidably inserted into the sleeve 29, and the spring 28 is elastically connected between the two.

[0034] The transmission assembly consists of a fixed roller group 12 and a pressure roller group 11, which are used to fix and intermittently transmit the plate. The fixed roller group 12 is fixedly installed on the inner wall of the side plate 10, and the upper end of the pressure roller group 11 is threaded to the upper end of the side plate 10. The pressure roller group 11 is fully engaged with the fixed roller group 12. A drive mechanism for driving the fixed roller group 12 to rotate intermittently is installed on the frame 1.

[0035] The drive mechanism includes a second motor 17, a main gear 18, an incomplete secondary gear 19, and a first pinion 21. The second motor 17 is fixedly mounted on the frame 1. The main gear 18 is coaxially fixedly connected to the output shaft of the second motor 17. The first pinion 21 is coaxially fixedly connected to a wheel of the fixed gear group 12. The incomplete secondary gear 19 is rotatably connected to the frame 1 and intermittently meshes with the first pinion 21. The main gear 18 and the incomplete secondary gear 19 are connected by a belt pulley.

[0036] In this embodiment, the material to be processed is placed above the workbench 3. The fixed roller group 12 and the pressure roller group 11 of the transmission component cooperate to form a stable clamp on the material, preventing the material from shifting during processing. Then, the drive mechanism is started, and the output shaft of the second motor 17 drives the main gear 18 to rotate. The main gear 18 drives the incomplete secondary gear 19 to rotate synchronously through the belt pulley. The incomplete secondary gear 19 intermittently meshes with the first pinion 21, which is coaxially fixed with the fixed roller group 12, thereby driving the fixed roller group 12 to rotate intermittently. This realizes the gradual transmission of the material according to the processing rhythm. This process can accurately match the time nodes of subsequent drilling and grinding processes, reduce waiting time between processes, and improve processing efficiency.

[0037] When the sheet metal is transferred to the corresponding position of the drilling assembly, the hydraulic push rod 5 is activated, and its telescopic end drives the motor drill 25 to move smoothly towards the sheet metal. The motor drill 25 operates to drill holes in the sheet metal. The stable telescopic characteristics of the hydraulic push rod 5 can ensure the accuracy of the drilling path of the motor drill 25, reduce the perpendicularity deviation between the drilling centerline and the sheet metal surface, improve drilling accuracy, and reduce subsequent correction processes.

[0038] The drilled board is then transferred to the grinding assembly. The first motor 6 starts, driving the reciprocating screw 7, which is coaxially fixed with its output shaft, to rotate. The screw nut 26 on the reciprocating screw 7 reciprocates accordingly. The screw nut 26 drives the grinding plate 30 to move synchronously through the connecting mechanism. The connecting rod 27 can slide inside the sleeve 29. The elasticity of the spring 28 ensures that the grinding plate 30 is always in close contact with the surface of the board, performing comprehensive grinding on the surface of the board after drilling. This effectively removes the burrs generated during drilling, eliminating the need for subsequent manual polishing, reducing the labor intensity of workers, and ensuring the flatness of the board surface, laying a good foundation for subsequent processing.

[0039] Example 2

[0040] Reference Figure 5-7 The difference between this embodiment and Embodiment 1 is that this embodiment also includes a cleaning component. The cleaning component consists of a water spray cylinder 24, a spray head 31, and a water pump cylinder 2, which is used to spray cleaning water onto the board to clean the surface of the board. The water spray cylinder 24 is fixed to the upper end of the side plate 10. Several spray heads 31 are provided on the side wall of the water spray cylinder 24 and communicate with it. The water pump cylinder 2 is fixedly installed on the frame 1 and communicates with the water spray cylinder 24 through the water outlet pipe 32. A water storage tank 8 is fixedly installed on the bottom plate 4. The water pump cylinder 2 is communicated with the water storage tank 8 through the water inlet pipe 23. A water pumping mechanism is installed on the frame 1.

[0041] The pumping mechanism includes a slide rail plate 35, a slide groove 36, a slider assembly 37, and a piston rod 39. The slide rail plate 35 is fixedly installed on the side plate 10. The slide groove 36 is opened on the side wall of the slide rail plate 35. The slider assembly 37 is vertically slidably connected in the slide groove 36. One end of the piston rod 39 is fixedly connected to the side wall of the slider assembly 37, and the other end is sealed and slidably connected to the inner wall of the pumping cylinder 2. A pushing mechanism that pushes the slider assembly 37 to slide vertically back and forth is installed on the frame 1.

[0042] The driving mechanism includes a rotating shaft 33 and a push rod 34. The rotating shaft 33 is rotatably connected to the frame 1. One end of the push rod 34 is rotatably connected to the extension of the rotating shaft 33, and the other end is rotatably connected to the lower end of the sliding assembly 37 via a rotating member 38. A transmission mechanism for driving the rotating shaft 33 to rotate is installed on the frame 1.

[0043] The transmission mechanism includes a full secondary gear 20 and a second pinion 22. Both the full secondary gear 20 and the second pinion 22 are rotatably connected to the frame 1. The full secondary gear 20 is connected to the main gear 18 via a pulley. The second pinion 22 is coaxially fixedly connected to the rotating shaft 33 and meshes with the full secondary gear 20.

[0044] The outlet pipe 32 is equipped with a one-way valve that allows liquid to flow only from the pump cylinder 2 to the spray cylinder 24, and the inlet pipe 23 is equipped with a one-way valve that allows liquid to flow only from the storage tank 8 to the pump cylinder 2.

[0045] In this embodiment, when the second motor 17 starts and drives the main gear 18 to rotate, the main gear 18 simultaneously drives the complete secondary gear 20 to rotate through the belt pulley transmission. The complete secondary gear 20 meshes with the second pinion 22, driving the rotating shaft 33, which is coaxially fixed with the second pinion 22, to rotate. When the rotating shaft 33 rotates, its extension drives one end of the push rod 34 to rotate synchronously. The other end of the push rod 34 pushes the slider assembly 37 to slide vertically back and forth in the slide groove 36 of the slide rail plate 35 through the rotating component 38. When the slider assembly 37 slides, it drives the piston rod 39 to slide in a sealed manner on the inner wall of the pump cylinder 2. When the piston rod 39 slides outward, a negative pressure is formed in the pump cylinder 2, and the one-way valve in the inlet pipe 23 opens, allowing clean water in the water storage tank 8 to be drawn into the pump cylinder 2 through the inlet pipe 23. When the piston rod 39 slides inward, the pressure in the pump cylinder 2 increases, and the one-way valve in the outlet pipe 32 opens, allowing clean water to be transported to the spray cylinder 24 through the outlet pipe 32. This process relies on the second motor 17 to achieve linkage between the cleaning component and the transmission, drilling and grinding components, eliminating the need for additional power devices, simplifying the equipment structure, reducing energy consumption, and improving overall operational coordination.

[0046] The cleaning water in the water spray cylinder 24 is evenly sprayed onto the surface of the board after drilling and polishing through several spray nozzles 31 on its side wall. On the one hand, it can quickly wash away the residual drilling debris and polishing powder on the surface of the board, avoid the adhesion of impurities and affect the subsequent processing accuracy, and reduce manual cleaning steps. On the other hand, when the cleaning water comes into contact with the board, it can absorb the heat generated during drilling and polishing, effectively reduce the temperature of the board, prevent the board from deforming due to high temperature, and ensure the processing quality of the board.

[0047] The one-way valves in the inlet pipe 23 and the outlet pipe 32 respectively restrict the clean water to flow only from the water storage tank 8 to the pump cylinder 2 and from the pump cylinder 2 to the spray cylinder 24, so as to avoid the backflow of clean water, which would cause a decrease in pump efficiency or sewage backflow to contaminate the clean water in the water storage tank 8. This lays the foundation for subsequent clean water recycling and filtration, reduces water waste, and lowers processing costs.

[0048] Example 3

[0049] Reference Figure 1-5 The difference from Embodiment 2 is that in this embodiment, the upper end of the water storage tank 8 is open, and a filter screen is provided at the upper end of the water storage tank 8.

[0050] In this embodiment, after the cleaning water sprayed from the spray head 31 has finished cleaning and cooling the board, the wastewater carrying debris and powder will fall naturally. Since the upper end of the water storage tank 8 is open, the wastewater can flow directly into the water storage tank 8. At the same time, the filter screen at the upper end of the water storage tank 8 will filter the falling wastewater, intercepting impurities such as drilling debris and grinding powder in the wastewater, preventing impurities from entering the water storage tank 8 and contaminating the cleaning water, ensuring the cleanliness of the water remaining in the water storage tank 8 after filtration, and meeting the requirements for cleaning the board again.

[0051] The filtered clean water can be drawn again by the pump cylinder 2 through the inlet pipe 23 when the pump mechanism is operating, and then transported to the spray cylinder 24 through the outlet pipe 32. The spray head 31 then sprays the cleaned plate again, forming a clean water circulation process. This process does not require frequent replenishment of new clean water to the water storage tank 8, which greatly reduces water consumption and lowers the cost of processing water. Moreover, the circulation process relies on the existing pump mechanism, check valve and other components in Embodiment 2, which is perfectly compatible with the overall power linkage system of the equipment. No additional circulation power device is required, which further simplifies the equipment structure and improves resource utilization efficiency and overall operational economy.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
