Description

Technical Field

[0001] The invention relates to the technical field of guide rail punching, and in particular to a punching device for producing drawer guide rails and a control method thereof. Background Art

[0002] Drawer guides are often installed in drawers as connecting moving parts, making the process of pulling the drawer smoother and more labor-saving, and can effectively reduce the friction generated by the contact between the drawer and the cabinet.

[0003] During the production process of drawer guides, the guide rail raw materials need to be punched out according to a certain size. However, most of the existing punching equipment directly blows away the waste chips generated in the punching area, which is not convenient for effectively collecting the waste chips generated by the punching, resulting in pollution of the working environment and affecting the cutting quality of the guide rails by the punching cutter head. In addition, as the punching process continues, under the impact force of the punching, the temperature of the punching knife will gradually rise. The increase in temperature will easily cause the waste chips to soften and increase in stickiness, causing the waste chips to adhere to the punching knife and be difficult to be blown off, affecting the subsequent punching effect. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a punching device and a control method for drawer guide rail production.

[0005] In a first aspect, the present invention provides a punching device for producing drawer guide rails, comprising a workbench, a lower mold with a lower punching opening is fixedly installed on the top of the workbench, an upper mold with an upper punching opening is fixedly installed on the top of the lower mold, and an insertion cavity is formed between the lower mold and the upper mold after being fixedly installed, and further comprising: A cutting knife is driven by a cutting drive mechanism to complete the cutting operation along the upper cutting opening and the lower cutting opening, and the cutting edge of the cutting knife is arranged in an arc shape; The installation port is opened through the side wall of the lower mold, a collection box is fixedly installed on the inner top of the installation port, the inner bottom surface of the collection box is arc-shaped, a rectangular frame is fixedly connected to the upper inner wall of the collection box, the frame opening of the rectangular frame is opposite to the lower punching port, and a discharge port is symmetrically opened through the bottom of the collection box; A vacuum cleaner is fixedly installed at the bottom of the workbench, and the suction port of the vacuum cleaner is fixedly connected with the two discharge ports through a three-way pipe; A temperature monitoring unit, used to monitor the temperature of the cutting edge of the punching knife; A cooling mechanism is arranged inside the collecting box and is used to cool the cutting edge of the punching knife; The control unit determines whether to control the operation of the cooling mechanism according to the monitoring result of the temperature monitoring unit; wherein, the control unit can be installed on the side wall of the workbench or control the punching equipment through an external connection, and the control unit is also used to control the punching drive mechanism to drive the punching knife to complete the punching operation along the upper punching opening and the lower punching opening, and control the vacuum cleaner to absorb the waste chips generated by the punching during the punching process, thereby reducing the impact of the splashing of waste chips on the working environment. When working, one end of the guide rail that needs to be punched is inserted into the lower mold and the upper mold. The guide rail is clamped by the manipulator, and after each cutting, the manipulator pushes the remaining guide rail to move the specified distance to continue the cutting operation, so as to ensure that the size of the guide rail cut off each time meets the set specified length, and the cut guide rail will fall onto the conveyor belt for transportation. The specific cutting process is that after the guide rail to be cut is inserted into the insertion cavity after the distance is adjusted, the control unit will control the cutting drive mechanism and the vacuum cleaner to operate, and the cutting drive mechanism drives the cutting knife to move downward along the upper cutting mouth to cut the guide rail in the insertion cavity, and Continue to enter the collection box along the lower punching opening. The vacuum cleaner uses the three-way pipe and the discharge port to suck air into the collection box. Under the action of suction, the waste chips generated in the punching process flow downward into the collection box with the airflow, reducing the flying of waste chips, thereby absorbing the waste chips generated in the punching process and reducing the amount of waste chips adhering to the cutting edge of the punching knife. After completing one punching, the punching drive mechanism will drive the punching knife to move up and reset to wait for the next punching. With the continuous punching operation, the temperature at the cutting edge of the punching knife may rise, and the temperature of the punching knife itself will increase. When the temperature rises, the waste chips soften due to the high temperature, making the waste chips stickier and more likely to stick to the cutting knife and difficult to blow away. Therefore, the temperature at the cutting edge of the cutting knife is monitored by a temperature monitoring unit. If the monitored temperature information value T1 exceeds the set temperature preset value T0, the waste chips generated by the cutting will become more sticky due to the increase in temperature. It is difficult to clean the waste chips at the cutting edge of the cutting knife through a single suction cleaning. At this time, the control unit will operate the cooling mechanism to cool the cutting edge of the cutting knife and assist the vacuum cleaner to collect the waste chips in a centralized manner.

An arc block is fixedly installed on the U-shaped frame, and the central axis of the arc block coincides with the central axis of the arc-shaped blade on the punching knife. The inner arc surface of the arc block and the surface of the arc-shaped blade are adapted to each other, and the arc block is symmetrically provided with a pushing surface; Two maintaining rollers are symmetrically connected to the side walls of the U-shaped frame, and the two maintaining rollers roll along the tracks of the two arc-shaped surfaces respectively; Two transverse driving mechanisms are arranged on the side walls of the sliding plate and are respectively used to drive the two sliding plates to slide transversely.

[0011] Preferably, the transverse driving mechanism includes a connecting seat and a motor, the connecting seat is fixedly connected to the side wall of the sliding plate, a threaded sleeve is fixedly embedded on the connecting seat, the motor is fixedly installed on the side wall of the collecting box, the output shaft end of the motor passes through the collecting box and extends to the inside of the collecting box and is fixedly connected to a threaded rod, and the threaded rod is threadedly connected to the threaded sleeve.

[0014] In a second aspect, a control method for a punching device for producing a drawer guide rail is provided, the control method comprising the following steps: The temperature monitoring unit monitors the temperature of the cutting edge of the punching knife and generates a temperature information value T; The temperature monitoring unit sends the temperature information value T to the control unit to determine whether to control the cooling mechanism to operate.

[0015] Preferably, the control process of the control unit in the control method includes the following process: The control unit matches the material information identified by the material identification unit to the corresponding temperature preset value T; The control unit substitutes the temperature preset value T0 and the temperature information value T1 into the judgment formula T0>T1. If the judgment formula is not met, the cooling mechanism is not started and the current process is terminated. If the judgment formula is met, the next process is executed; The control unit generates first control information and second control information according to the judgment result; The control unit first sends the first control information to the pushing and cleaning component to control the pushing and cleaning component to clean the waste adhered to the arc-shaped blade edge of the punching knife; The control unit then sends the second control information to the water pump to control the water pump to transport water into the water storage chamber, and sprays the water onto the arc-shaped blade edge of the punching knife with the help of an atomizing nozzle.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Insert one end of the guide rail to be cut into the insertion cavity between the lower mold and the upper mold, and clamp the guide rail with the help of a manipulator. After each cutting, the manipulator will push the remaining guide rail to move the specified distance to continue the cutting operation, so as to ensure that the size of the guide rail cut off each time meets the set specified length, and the cut guide rail will fall onto the conveyor belt for transportation. The specific cutting process is that after the distance is adjusted, the guide rail to be cut is inserted into the insertion cavity, and the control unit will control the cutting drive mechanism and the vacuum cleaner to operate, and the cutting will be completed. The breaking drive mechanism drives the cutting knife to move downward along the upper breaking opening, breaks the guide rail in the inserted cavity, and continues to enter the collection box along the lower breaking opening. The vacuum cleaner uses the three-way pipe and the discharge port to suck air into the collection box. Under the action of suction, the waste chips generated in the breaking process flow downward into the collection box with the air flow, reducing the flying of waste chips, thereby absorbing the waste chips generated in the breaking process and reducing the amount of waste chips adhering to the cutting edge of the cutting knife. After completing one breaking, the breaking drive mechanism will drive the cutting knife to move upward and reset to wait for the next breaking.

[0017] 2. The temperature rises at the cutting edge of the punching knife, which easily causes the waste chips to become more sticky, and it is difficult to completely clean them off with airflow cleaning. Therefore, when the temperature information value T1 monitored by the temperature monitoring unit exceeds the set temperature preset value T0, the control unit first controls the cleaning component to operate, and pushes the waste chips adhering to the cutting edge of the punching knife, so that the waste chips are separated from the cutting edge, thereby facilitating the absorption and cleaning of the vacuum cleaner. Then, the control unit starts the water pump, and the water pump will transport the water flow in the water supply tank to the inside of the water storage chamber, and use multiple atomizing nozzles to spray water mist to the cutting edge of the punching knife entering the collection box, which can quickly reduce the cutting edge temperature and prevent the cutting edge from overheating and affecting the processing quality and the stickiness of the waste chips. The design of the arc cover ensures that the water mist can accurately cover the cutting edge area and improve the cooling efficiency. The water supply tank and the water pump form a water supply system to ensure the continuity and stability of the cooling process.

[0018] 3. Two arc plates are symmetrically fixedly connected to the bottom of the rectangular frame, and each arc plate is provided with an arc surface and an arc opening extending therethrough. The central axes of the arc surface and the arc opening coincide with the central axes of the arc-shaped blade on the punching knife. This design ensures that the arc block can fit tightly to the blade surface during the cleaning process, and the working process of pushing the cleaning component is as follows: the control unit controls the operation of the two transverse driving mechanisms, and the two transverse driving mechanisms drive the two sliding plates to move transversely along the bottom of the rectangular frame. During the transverse movement of the sliding plate, the inner wall of the vertical opening on the sliding plate will push the guide pin inside it, and the maintenance roller connected to the side wall of the U-shaped frame will move along the arc surface due to rotation. The track rolls, and the design of the maintenance roller ensures the stability and smoothness of the entire cleaning process. Therefore, under the push of the inner wall of the vertical opening, the guide pin is prompted to move along the track of the arc-shaped opening. In this process, the pushing surface of the arc block installed on the U-shaped frame pushes the waste chips on the blade and pushes down the waste chips stuck to the blade. On the one hand, it is convenient for the vacuum cleaner to absorb it, and on the other hand, the removal of waste chips helps to reduce heat accumulation, and also creates favorable conditions for subsequent cooling treatment. The design of the entire pushing and cleaning component fully considers the special shape and cleaning requirements of the cutting blade, and achieves efficient and comprehensive cleaning effects through the coordinated work of multiple components.

DETAILED DESCRIPTION

[0030] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0031] Application scenario: In a factory that mass-produces drawer rails, the punching equipment is arranged in the middle of the production line. The equipment needs to process thousands of rails of different materials every day, including but not limited to aluminum alloy, stainless steel and carbon steel. During the production process, operators found that a large amount of fine metal scraps often accumulated around the punching equipment. These scraps not only caused environmental pollution, but also increased the workload of cleaning and maintenance. What is more serious is that some scraps will float into the air, posing a potential threat to the health of workers. In addition, when the same material rails are punched continuously for a certain period of time, the temperature of the punching knife will increase significantly. For example, when processing stainless steel rails, the temperature of the punching knife may rise from room temperature to more than 100°C within 30 minutes. This temperature increase makes it easier for scraps to adhere to the blade, which is difficult to remove by simple airflow cleaning. This not only affects the punching accuracy, but also accelerates the wear of the tool. Furthermore, if the problems of waste chip collection and temperature control of the punching knife cannot be effectively solved, it will have a series of negative effects on the entire drawer guide production process. First, the accumulation of waste chips will increase the failure rate of the equipment, because fine metal particles may penetrate into the moving parts of the equipment, accelerate wear and cause poor operation. Secondly, the waste chips adhering to the punching knife will affect the accuracy of the punching, resulting in a decline in product quality, and increase rework and scrap rates, which will not only increase production costs, but also extend the production cycle. In addition, frequent cleaning and maintenance operations will significantly reduce the utilization rate of the equipment and affect the efficiency of the entire production line. In the long run, if these problems are not effectively solved, the company's market competitiveness will be weakened and it may face regulatory pressure due to environmental and safety issues. Therefore, the development of a new type of punching equipment that can effectively collect waste chips and intelligently control the temperature of the punching knife according to the characteristics of guide rails of different materials is of great significance to improving the production efficiency and quality of drawer guides. Faced with the problems of waste chip collection and temperature control of the punching knife in the punching process of drawer guide production, the R&D team conducted in-depth thinking and analysis.

[0032] like Figures 1 to 10 The punching equipment for producing drawer guide rails shown in the figure comprises a workbench 1, a lower mold 2 with a lower punching opening 201 is fixedly installed on the top of the workbench 1, an upper mold 3 with an upper punching opening 301 is fixedly installed on the top of the lower mold 2, and an insertion cavity 4 is formed between the lower mold 2 and the upper mold 3 after being fixedly installed, and further comprises: The punching knife 5 is driven by the punching driving mechanism to complete the punching operation along the upper punching opening 301 and the lower punching opening 201, and the blade of the punching knife 5 is set in an arc shape; The installation port is opened through the side wall of the lower mold 2, and a collection box 6 is fixedly installed on the inner top of the installation port. The inner bottom surface of the collection box 6 is arc-shaped, and a rectangular frame 601 is fixedly connected to the upper inner wall of the collection box 6. The frame opening of the rectangular frame 601 is opposite to the lower punching port 201, and a discharge port 602 is symmetrically opened through the bottom of the collection box 6; A vacuum cleaner 7 is fixedly installed at the bottom of the workbench 1, and a suction port of the vacuum cleaner 7 is fixedly connected to the two discharge ports 602 through a three-way pipe 701; A temperature monitoring unit, used to monitor the temperature of the cutting edge of the punching knife 5; A cooling mechanism is arranged inside the collecting box 6 and is used to cool the cutting edge of the punching knife 5; The control unit determines whether to control the cooling mechanism to operate according to the monitoring result of the temperature monitoring unit.

[0033] Among them, the control unit can be installed on the side wall of the workbench 1 or control the punching equipment through an external connection. The control unit is also used to control the punching drive mechanism to drive the punching knife 5 to complete the punching operation along the upper punching opening 301 and the lower punching opening 201, and control the vacuum cleaner 7 to absorb the waste chips generated by the punching during the punching process, thereby reducing the impact of the splashing of waste chips on the working environment. During work, one end of the guide rail that needs to be punched is inserted into the insertion cavity 4 between the lower mold 2 and the upper mold 3, and the guide rail is clamped with the help of the manipulator 32. And after each cutting is completed, the manipulator 32 will push the remaining guide rails to move the specified distance to continue the cutting operation, so as to ensure that the size of the guide rails cut off each time meets the set specified length, and the cut guide rails will fall onto the conveyor belt 33 for transportation. The specific cutting process is that after the guide rail to be cut is inserted into the insertion cavity 4 after the distance is adjusted, the control unit will control the cutting drive mechanism and the vacuum cleaner 7 to operate, and the cutting drive mechanism drives the cutting knife 5 to move downward along the upper cutting opening 301, cuts the guide rails in the insertion cavity 4, and continues to enter the collection along the lower cutting opening 201. Inside the box 6, the vacuum cleaner 7 uses the three-way pipe 701 and the discharge port 602 to suck air into the collection box 6. Under the action of suction, the waste chips generated during the punching process flow downward into the collection box 6 along with the air flow, reducing the flying of the waste chips, thereby absorbing the waste chips generated during the punching process and reducing the amount of waste chips adhering to the cutting edge of the punching knife 5. After completing one punching operation, the punching drive mechanism will drive the punching knife 5 to move up and reset to wait for the next punching. As the continuous punching operation proceeds, the temperature at the cutting edge of the punching knife 5 may rise, and the temperature of the punching knife 5 itself will increase. When the temperature rises, the waste chips soften due to the high temperature, making the waste chips stickier and more likely to stick to the cutting knife 5 and difficult to blow away. Therefore, the temperature at the cutting edge of the cutting knife 5 is monitored by a temperature monitoring unit. If the monitored temperature information value T1 exceeds the set temperature preset value T0, the waste chips generated by the cutting will become more sticky due to the increase in temperature. It is difficult to clean the waste chips at the cutting edge of the cutting knife 5 through a single suction cleaning. At this time, the control unit will operate the cooling mechanism to cool the cutting edge of the cutting knife 5, and assist the vacuum cleaner 7 to collect the waste chips in a centralized manner.

[0034] The temperature monitoring unit may be a sensor capable of detecting temperature in the prior art and may be arranged on the punching blade 5 .

[0035] Compared with the prior art, the punching equipment of the present application embodies innovation and progress in the following aspects: First, the arc-shaped bottom surface design of the collection box 6 matches the shape of the blade of the punching knife 5, which greatly improves the efficiency and accuracy of waste chip collection. Traditional equipment often uses a flat collection box, which is difficult to effectively collect the waste chips generated by the arc-shaped blade. Secondly, the introduction of the intelligent cooling system realizes the precise control of the temperature of the punching knife 5. The prior art mostly adopts timed cooling or continuous cooling, which not only has a poor cooling effect, but also may cause energy waste. The present application ensures the cooling effect and improves energy utilization through real-time temperature monitoring and threshold control. Furthermore, the present application organically combines the waste chip collection system with the cooling system, and simultaneously processes the waste chips and the atomized coolant through the vacuum cleaner 7, thereby realizing the integration of equipment functions and improving overall work efficiency. Finally, the arc-shaped design of the blade of the punching knife 5 not only improves the punching effect, but also forms a good match with the collection box 6 and the cooling system, reflecting the integrity and coordination of the design. This design concept is relatively rare in the prior art; through these innovative designs, the punching equipment of the present application effectively solves the problems of difficulty in collecting waste chips and improper temperature control of the punching knife in the production of drawer guides, and provides reliable technical support for the efficient and precise production of drawer guides.

[0036] As an embodiment of the present invention, the cutting drive mechanism includes a gantry, which is fixedly connected to the top of the workbench 1. A cylinder 8 is fixedly installed on the top of the gantry. The piston rod end of the cylinder 8 passes downward through the gantry and is fixedly connected to a mounting seat 9. The mounting seat 9 and the cutting knife 5 are fixedly connected by bolts. When working, the gantry is provided to provide a stable support structure for the cutting drive mechanism. The control unit starts the cylinder 8, and the output shaft of the cylinder 8 pushes the cutting knife 5 to move vertically, so that it can accurately move along the upper cutting opening 301 and the lower cutting opening 201, thereby realizing accurate cutting of the drawer guide rail. The bolt connection method facilitates the replacement and maintenance of the cutting knife 5, thereby improving the flexibility and service life of the equipment.

[0037] As an embodiment of the present invention, an auxiliary collection mechanism is provided below the inner wall of the upper punching opening 301, and air is blown toward the surface of the punching knife 5 during the punching process to blow the waste chips downward for auxiliary collection, and the auxiliary collection mechanism includes: Two sealing cavities 10 are symmetrically opened on the top of the upper mold 3. Sealing plates 11 are respectively arranged inside the two sealing cavities 10. The side walls of the sealing plates 11 are in sealing contact with the inner walls of the sealing cavities 10 through sealing plugs. The tops of the two sealing plates 11 are fixedly connected to the bottom of the mounting seat 9 through connecting columns 12. Two one-way air inlet valves 13 are fixedly mounted on the two sealing plates 11 respectively; Two inclined surfaces 14 are symmetrically arranged below the inner wall of the upper punching opening 301, and a plurality of one-way air outlet valves 15 connected with the inside of the adjacent sealed chamber 10 are fixedly installed on each inclined surface 14; during operation, when the mounting seat 9 drives the punching knife 5 to move downward for punching, the mounting seat 9 drives the sealing plate 11 to descend synchronously with the help of the connecting column 12, compressing the air in the sealed chamber 10, thereby prompting the one-way air outlet valve 15 on the inclined surface 14 to open, and the airflow is ejected downward with the help of the one-way air outlet valve 15 to form a downward airflow, and the waste chips generated by the punching are blown downward into the collection box 6 under the blowing of the airflow, and the auxiliary vacuum cleaner 7 collects the waste chips generated in the punching process to reduce the adhesion of the waste chips on the punching knife 5, and when the punching knife 5 rises, the one-way air inlet valve 13 opens, and air enters the sealed chamber 10 to prepare for the next punching jet; The auxiliary collection mechanism utilizes the reciprocating motion of the punching knife 5 to automatically generate airflow without the need for an additional power source, which greatly simplifies the equipment structure and reduces energy consumption. The sealed space formed by the sealing cavity 10 and the sealing plate 11 can effectively store and compress air. The cooperation of the one-way air inlet valve 13 and the one-way air outlet valve 15 ensures the one-way flow of the airflow and improves the efficiency of airflow utilization. The design of the inclined surface 14 enables the airflow to be accurately guided to the punching area, effectively blowing waste chips downward.

[0038] As an embodiment of the present invention, the cooling mechanism includes: A push cleaning component is used to clean the waste chips adhering to the arc-shaped blade edge of the punching knife 5 after punching; A water storage chamber 18 is provided on the inner bottom surface of the collecting box 6. An arc-shaped cover plate 16 is fixedly installed at the opening of the water storage chamber 18. The arc shape of the arc-shaped cover plate 16 matches the arc shape of the blade on the punching knife 5. A plurality of atomizing nozzles 17 connected to the inside of the water storage chamber 18 are fixedly installed on the arc-shaped cover plate 16. The water supply tank is fixedly installed under the workbench 1, and a water pump 19 is fixedly installed on the side wall of the water supply tank. The water inlet pipe of the water pump 19 is fixedly connected to the inside of the water supply tank, and the water outlet pipe of the water pump 19 is fixedly connected to the inside of the water storage chamber 18. When working, the temperature at the cutting edge of the punching knife 5 rises, which easily causes the stickiness of the waste chips to increase, and it is difficult to clean them up completely by airflow cleaning. Therefore, when the temperature information value T1 monitored by the temperature monitoring unit exceeds the set temperature preset value T0, the control unit first controls the operation of the cleaning component to push the waste chips adhered to the cutting edge of the punching knife 5, so that the waste chips are removed. The chips are separated from the blade, which is convenient for the vacuum cleaner 7 to absorb and clean them. Then, the control unit starts the water pump 19, which transports the water in the water supply tank to the water storage chamber 18, and uses multiple atomizing nozzles 17 to spray water mist to the blade of the punching knife 5 entering the collection box 6. The blade temperature can be quickly reduced to prevent the blade from overheating and affecting the processing quality and the stickiness of the waste chips. The design of the arc cover 16 ensures that the water mist can accurately cover the blade area and improve the cooling efficiency. The water supply tank and the water pump 19 form a water supply system to ensure the continuity and stability of the cooling process.

[0039] In practical applications, the cooling mechanism of the present application can be used in conjunction with a temperature monitoring unit and a control unit. For example, the temperature threshold can be set to 100°C. When the temperature monitoring unit detects that the cutting edge temperature of the punching knife 5 exceeds 100°C, the control unit will first start to push the cleaning component to clean the waste chips. After the cleaning is completed, the water pump 19 will be started immediately to spray water mist through the atomizing nozzle 17. The water mist spraying time can be set to 5 to 10 seconds. The specific time can be adjusted according to the actual cooling effect. If the temperature is still higher than the threshold after one cooling, the system will automatically perform a second cooling cycle.

[0040] As an embodiment of the present invention, the cleaning component is pushed to include: Two arc-shaped plates 20 are symmetrically fixedly connected to the bottom of the rectangular frame 601, each arc-shaped plate 20 is provided with an arc-shaped surface 2001, each arc-shaped plate 20 is penetrated with an arc-shaped opening 2002, and the central axis of the arc-shaped surface 2001 and the arc-shaped opening 2002 coincides with the central axis of the arc-shaped blade of the punching knife 5; Two sliding plates 21 are symmetrically slidably connected to the bottom of the rectangular frame 601, and vertical openings 22 are formed through the side walls of the two sliding plates 21; Two guide pins 23 are respectively arranged inside the two arc-shaped openings 2002, and the opposite ends of the two guide pins 23 are rotatably connected with a U-shaped frame 24. The opposite ends of the two guide pins 23 extend to adjacent vertical openings 22 respectively. An arc block 25 is fixedly installed on the U-shaped frame 24. The central axis of the arc block 25 coincides with the central axis of the arc-shaped blade of the knife 5. The inner arc surface of the arc block 25 is adapted to the surface of the arc-shaped blade, and the arc block 25 is symmetrically provided with a pushing surface 2501. Two maintaining rollers 26 are symmetrically connected to the side walls of the U-shaped frame 24, and the two maintaining rollers 26 roll along the tracks of the two arc-shaped surfaces 2001 respectively; Two transverse driving mechanisms are arranged on the side walls of the sliding plate 21, and are respectively used to drive the two sliding plates 21 to slide transversely; when working, the two arc plates 20 are symmetrically fixedly connected to the bottom of the rectangular frame 601, and each arc plate 20 is provided with an arc surface 2001 and an arc opening 2002 opened therethrough, and the central axis of the arc surface 2001 and the arc opening 2002 coincide with the central axis of the arc-shaped blade on the punching knife 5. This design ensures that the arc block 25 can fit tightly against the blade surface during the cleaning process, and the working process of pushing the cleaning component is that the control unit controls the operation of the two transverse driving mechanisms, and the two transverse driving mechanisms drive the two sliding plates 21 to move transversely along the bottom of the rectangular frame 601. During the transverse movement of the sliding plate 21, the inner wall of the vertical opening 22 on the sliding plate 21 will push the guide pin 23 inside it. The maintenance roller 26 connected to the side wall of the U-shaped frame 24 will roll along the trajectory of the arc surface 2001, and the design of the maintenance roller 26 ensures the stability and smoothness of the entire cleaning process. Therefore, under the push of the inner wall of the vertical opening 22, the guide pin 23 is prompted to move along the trajectory of the arc opening 2002. In this process, the pushing surface 2501 of the arc block 25 installed on the U-shaped frame 24 pushes the waste chips on the blade and pushes down the waste chips stuck to the blade. On the one hand, it is convenient for the vacuum cleaner 7 to absorb them. On the other hand, the removal of waste chips helps to reduce heat accumulation and also creates favorable conditions for subsequent cooling treatment. The design of the entire pushing and cleaning component fully considers the special shape and cleaning requirements of the blade of the punching knife 5, and achieves efficient and comprehensive cleaning effects through the coordinated work of multiple components.

[0041] The arc block 25 is symmetrically provided with a pushing surface 2501 , and the angle of the pushing surface 2501 can be designed to be 30-45 degrees to effectively push the waste chips.

[0042] As an embodiment of the present invention, the transverse driving mechanism includes a connecting seat 29 and a motor 27. The connecting seat 29 is fixedly connected to the side wall of the sliding plate 21. A threaded sleeve is fixedly embedded on the connecting seat 29. The motor 27 is fixedly installed on the side wall of the collecting box 6. The end of the output shaft of the motor 27 passes through the collecting box 6 and extends to the inside thereof, and is fixedly connected to a threaded rod 28. The threaded rod 28 is threadedly connected to the threaded sleeve. When working, the control unit starts the motor 27, and the output shaft of the motor 27 drives the threaded rod 28 to rotate. Since the threaded rod 28 is connected to the threaded sleeve, the threaded rod 28 is connected to the threaded sleeve. The sleeve is threadedly connected, so the rotating threaded rod 28 is driven by the threaded sleeve on the connecting seat 29 to drive the sliding plate 21 to achieve horizontal sliding. The motor 27 uses a forward and reverse stepping motor 27. The forward and reverse rotation of the motor 27 realizes the reciprocating movement of the sliding plate 21, thereby driving the arc block 25 to reciprocate along the arc trajectory. Since the pushing surface 2501 is symmetrically provided on the arc block 25, no matter whether the motor 27 rotates forward or reverse, the arc block 25 can clean and push the waste chips at the arc-shaped blade of the punching knife 5, thereby increasing the applicability and flexibility of the equipment.

[0043] As an embodiment of the present invention, mounting columns 30 are symmetrically fixedly connected to the side walls of the U-shaped frame 24, and the ends of the two mounting columns 30 are commonly fixedly connected to a push plate 31, and the push surface 2501 of the push plate 31 is mutually compatible with the inner bottom surface of the collecting box 6; during operation, when the U-shaped frame 24 drives the arc block 25 to clean the blade of the punching knife 5, the push plate 31 connected to the U-shaped frame 24 will also move synchronously. Since the push plate 31 is mutually compatible with the inner bottom surface of the collecting box 6, their movement can push the waste accumulated at the bottom of the cleaning collecting box 6 to the discharge port 602, thereby facilitating the vacuum cleaner 7 to quickly absorb and collect it. This synchronous cleaning mechanism not only improves the cleaning efficiency, but also keeps the bottom of the collecting box 6 clean, preventing the accumulation of waste from affecting the normal operation of the equipment.

[0044] Compared with the prior art, the technical solution of the present application has obvious advantages. Traditional punching equipment usually only focuses on the cleaning of the punching knife 5, but ignores the cleaning and maintenance of the bottom of the collection box 6, which causes waste chips to gradually accumulate at the bottom of the collection box 6, which not only affects the collection efficiency of the waste chips, but may also interfere with the normal operation of the cooling mechanism. The present application achieves the synchronous cleaning of the punching knife 5 and the bottom of the collection box 6 through a simple and ingenious structural design without adding an additional power source.

[0045] As an embodiment of the present invention, the punching equipment also includes a material identification unit, which is arranged on the top of the workbench 1 and is used to identify the material type of the guide rail to be punched. A material information database containing common slide rail parts to be processed is established in the control unit, and each type of material information corresponds to a temperature preset value T0.

[0046] During operation, guide rails of different materials cause different temperature points at which waste chips become sticky. It is difficult for existing technologies to be flexibly adjusted according to different materials. These problems seriously affect the efficiency and quality of drawer guide rail production. The present technical solution can solve the above problems. The specific implementation method is as follows: the material identification unit is arranged on the top of the workbench 1, and can identify the material type of the guide rail to be punched and processed. This feature enables the equipment to automatically identify different types of guide rail materials and provide basic data for subsequent temperature control. A database containing material information of common slide rail parts to be processed is established in the control unit. Each material type corresponds to a temperature preset value T0. This feature enables the system to identify the material according to the identified material. type, quickly matches to the corresponding temperature preset value, provides a reference standard for temperature control in the cutting process, through the cooperation of the material recognition unit and the material information database, this technical solution can automatically set the appropriate temperature preset value T0 according to the characteristics of different guide rail materials; this technical solution forms a closed-loop control system with the temperature monitoring unit and the cooling mechanism in the previous embodiment, the material recognition unit provides material information, the control unit matches the temperature preset value T0 according to the database, the temperature monitoring unit monitors the temperature of the cutting knife 5 in real time, when the temperature exceeds the preset value, the control unit will start the cooling mechanism, this precise temperature control not only improves the cutting quality, but also extends the service life of the cutting knife 5.

[0047] The material recognition unit can be implemented in a variety of ways. For example, optical recognition technology can be used to capture images of the guide rail surface through a high-resolution camera and combine them with image processing algorithms to identify the material. Another method is to use electromagnetic induction technology to determine the type of the material by measuring its electromagnetic properties. In addition, X-ray fluorescence spectroscopy analysis technology can be used to determine the material by analyzing the elemental composition of the material surface.

[0048] A specific embodiment is as follows: During a drawer guide rail production process, a batch of aluminum alloy guide rails are to be processed. The material identification unit identifies that the material of the guide rails is aluminum alloy through optical identification technology. The control unit then finds relevant information of the material in the material information database. The system automatically sets the temperature preset value T0 to 120°C. During the cutting process, the temperature monitoring unit continuously monitors the temperature of the cutting knife 5. When the temperature exceeds 120°C, the control unit immediately activates the cooling mechanism. First, the cleaning component is pushed to quickly clean the waste chips on the surface of the cutting knife 5, and then the water pump 19 is started to spray cooling water mist to the cutting knife 5 through the atomizing nozzle 17. At the same time, the cutting process is paused to wait for the temperature to drop to a safe range.

[0049] A control method for a punching device for producing a drawer guide rail, the control method comprising the following steps: The temperature monitoring unit monitors the temperature of the cutting edge of the punching knife 5 and generates a temperature information value T1; The temperature monitoring unit sends the temperature information value T1 to the control unit to determine whether to control the cooling mechanism to operate.

[0050] As an implementation of the present invention, the control process of the control unit in the control method includes the following process: The control unit matches the material information identified by the material identification unit to the corresponding temperature preset value T0; The control unit substitutes the temperature preset value T0 and the temperature information value T1 into the judgment formula T0>T1. If the judgment formula is not met, the cooling mechanism is not started and the current process is terminated. If the judgment formula is met, the next process is executed; The control unit generates first control information and second control information according to the judgment result; The control unit first sends the first control information to the pushing and cleaning component to control the pushing and cleaning component to clean the waste adhered to the arc-shaped blade edge of the punching knife 5; The control unit then sends the second control information to the water pump 19 to control the water pump 19 to transport water into the water storage chamber 18 and spray the water onto the arc-shaped blade edge of the punching knife 5 through the atomizing nozzle 17 .

[0051] The working principle of the present invention is as follows: one end of the guide rail to be cut is inserted into the insertion cavity 4 between the lower mold 2 and the upper mold 3, and the guide rail is clamped by means of the manipulator 32, and after each cutting is completed, the manipulator 32 will push the remaining guide rail to move a specified distance to continue the cutting operation, thereby ensuring that the size of the guide rail cut off each time meets the set specified length, and the cut guide rail will fall onto the conveyor belt 33 for transportation. The specific cutting process is that after the guide rail to be cut is inserted into the insertion cavity 4 after the distance is adjusted, the control unit will control the cutting drive mechanism and the vacuum cleaner 7 to operate, and the cutting drive mechanism drives the cutting knife 5 to move downward along the upper cutting opening 301 to cut the guide rail in the insertion cavity 4, and continue to enter the collection box 6 along the lower cutting opening 201, and the vacuum cleaner 7 uses the three-way pipe 701 and the discharge port 602 to perform a suction operation on the inside of the collection box 6. Under the action of the suction force, the waste chips generated during the cutting process flow downward with the airflow to In the collection box 6, the flying of waste chips is reduced, so that the waste chips generated during the punching process are absorbed and the amount of waste chips adhering to the cutting edge of the punching knife 5 is reduced. After completing one punching, the punching drive mechanism will drive the punching knife 5 to move up and reset to wait for the next punching. With the continuous punching operation, the temperature at the cutting edge of the punching knife 5 may rise. When the temperature of the punching knife 5 itself rises, the waste chips soften due to the high temperature, making the waste chips sticky and more likely to adhere to the punching knife 5 and difficult to blow away. Therefore, the temperature at the cutting edge of the punching knife 5 is monitored by the set temperature monitoring unit. If the monitored temperature information value T1 exceeds the set temperature preset value T0, the waste chips generated by the punching will become more sticky due to the increase in temperature. It is difficult to clean the waste chips at the cutting edge of the punching knife 5 through a single suction cleaning. At this time, the control unit will operate the cooling mechanism to cool the cutting edge of the punching knife 5, and the auxiliary vacuum cleaner 7 can realize centralized collection of the waste chips.
