Description

Technical Field

[0001] The invention relates to the field of automatic bending of the short sides of plates, and in particular to an automatic bending structure of the short sides of plates. Background Art

[0002] In the field of folding machines, traditional short-side bending molds have many shortcomings. For example, in the CN201822234565.2 patent previously authorized by the applicant, the short knife mold does not have an automatic adjustment function. When faced with short-side bending tasks of different lengths, it is necessary to manually disassemble and assemble the mold structure and combine the mold length according to the folded length. Every time a bending requirement of different lengths is encountered, this disassembly and assembly process must be repeated, which not only consumes a lot of time, resulting in extremely low work efficiency, but also increases the labor intensity of workers. Summary of the invention

[0003] In order to fill the gap in the market, the present invention provides an automatic bending structure for the short sides of a plate.

[0004] The object of the present invention is to provide an automatic bending structure for the short edges of a plate to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a short edge automatic bending structure of a plate, comprising: A frame, wherein a linear guide rail is arranged inside the frame; An automatic adjustable short knife folding die set, wherein the two ends of the linear guide rail are respectively provided with the automatic adjustable short knife folding die set, the automatic adjustable short knife folding die set is composed of a plurality of short knife folding dies arranged side by side, and a mounting seat is fixed at the lower end of the automatic adjustable short knife folding die set, and a guide rail seat which can slide on the linear guide rail is connected to the lower end of the mounting seat; Platform, platforms fixed to the frame are respectively connected below both ends of the linear guide rail, synchronous pulleys are horizontally placed on each platform, the synchronous pulleys on the platforms on both sides are connected by synchronous belts, a connecting plate is fixed near the inner side of the platform, the connecting plate is connected to the synchronous belt, and adjacent short knife folding molds are connected to each other through a hook assembly; A hook assembly, comprising a guide seat, a hook, a guide strip, a spring, a baffle, a support block and a cylindrical pin. The guide seat is provided with a hook groove structure for placing the hook, a groove on one side of the hook is connected to the seat body of the adjacent guide seat, and a pin hole on one side of the hook is connected to the guide seat through a cylindrical pin so that it can rotate. The spring can place the hook in a locking position when it is at a free length. The baffles are placed at both ends of the guide seat for positioning the short mold, and the support block is placed at the rear of the guide seat for adjusting the position accuracy of the short mold; The latch device comprises a guide sleeve, a support, a cylinder and a push rod. The guide sleeve is connected to the front side of the support. The push rod is connected to the cylinder and is located inside the guide sleeve. The support is installed above the platform near the inside. The push rod can be extended and retracted when the cylinder is in a state of air inlet and outlet. The servo motor, under the control of the CNC system, drives the synchronous pulley to rotate, thereby driving the synchronous belt and the automatic adjustable short knife folding die set to move back and forth on the linear guide rail.

[0006] Furthermore, the guide seat and the short knife folding mold in the hook assembly are split structures, so that the shape of the short knife folding mold can be customized according to actual needs.

[0007] Furthermore, the automatic adjustable short-knife folding die set can achieve any length by increasing or decreasing the number of short-knife folding dies or adjusting their combination, so as to adapt to the short-side bending processing of plates of various specifications.

[0008] Furthermore, the hook assembly realizes the separation and overlap operations between adjacent short knife folding molds through a latch device. Under the precise control of the CNC system, when the folding length needs to be adjusted, the latch device can accurately control the state of the hook, so that the combination adjustment process of the short knife folding mold can be automated.

[0009] Furthermore, the synchronous belt, driven by the servo motor, can smoothly and accurately drive the automatic adjustable short knife folding die set to move on the linear guide rail.

[0010] Furthermore, the baffle and the guide seat are connected in a detachable manner, which is convenient for replacing a suitable baffle according to the size requirements of different short molds.

[0011] Furthermore, the height of the support block is adjustable. By adjusting the height of the support block, the height difference generated during the installation and use of the short knife folding mold can be accurately compensated, thereby ensuring the consistency of adjacent short knife folding molds in the height direction.

[0012] Furthermore, the cylinder is electrically connected to a numerical control system, which can accurately control the air ventilation time and stroke of the cylinder according to preset folding length and process parameters, so that the telescopic action of the push rod and the driving action of the servo motor can cooperate to achieve precise adjustment of the combined length of the short knife folding mold.

[0013] Furthermore, the connection between the connecting plate, the synchronous belt and the platform adopts a high-strength fastening method to ensure that when the synchronous belt drives the mold group to move, the connecting plate can stably transmit power without loosening or deformation.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The hook assembly of the present invention can realize the separation and overlap operations between adjacent short knife folding molds with the help of a latch device, and under the precise control of the numerical control system, the length adjustment process of the entire short knife folding mold group is completed automatically, which greatly improves work efficiency, reduces manual intervention, and reduces labor intensity.

[0015] The short mold assembly adopts a serialized design and can be flexibly adjusted to any length according to actual needs, so as to adapt to the short side bending processing of various specifications of plates, which greatly enhances the versatility of the equipment and can better cope with diversified production tasks.

[0016] The mold and hook assembly are split structures, so that the mold shape can be customized according to specific processing requirements, further improving the adaptability of the entire bending structure to the processing of different plates and meeting complex and changing production needs.

[0017] Driven precisely by the servo motor, the synchronous belt can smoothly and accurately drive the die set to move on the linear guide rail, ensuring the position accuracy of the die during movement, effectively reducing the bending error caused by die position deviation, and improving the accuracy and quality of the short side bending of the sheet.

[0018] The support block is height-adjustable, which can accurately compensate for the height difference of the mold during installation and use, ensure that adjacent molds remain consistent in height, and make the plate evenly stressed during bending, further improving the bending quality and stability.

[0019] The baffle and guide seat are detachably connected, which is convenient for replacing the appropriate baffle, helps to improve the accuracy of short mold positioning, and also facilitates the maintenance and adjustment of the equipment, so that the equipment can better adapt to different molds and enhance the overall reliability of the equipment.

[0020] The high-precision sliding fit between the guide rail seat and the linear guide rail reduces the friction and shaking when the mold group moves, which not only improves the stability and straightness of the movement, ensures the bending accuracy, but also reduces the wear of the guide rail and the guide rail seat, and extends the service life of the equipment.

[0021] The high-strength fastening connection between the connecting plate, the synchronous belt and the platform ensures the stable transmission of power during the transmission process, avoids loosening or deformation, ensures the reliability and stability of the entire transmission system, and provides a strong guarantee for continuous and stable bending processing.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The present invention provides a technical solution: an automatic bending structure for the short side of a plate. First, a frame 1 is prepared, and a linear guide rail 2 is accurately installed inside the frame 1 to ensure the installation accuracy of the linear guide rail 2 so that it can provide stable and accurate guidance for the subsequent movement of the mold group. The installation of the linear guide rail 2 must ensure that its levelness and straightness meet the design requirements. It can be calibrated by a high-precision measuring instrument, such as using a laser level to measure and adjust, so that the deviation of the linear guide rail 2 in the horizontal and vertical directions is controlled within a very small range.

[0026] An automatic adjustable short knife folding die set 3 is installed at both ends of the linear guide rail 2. The assembly process of the automatic adjustable short knife folding die set 3 is as follows: a number of short knife folding dies 5 are arranged side by side according to the design requirements, and adjacent short knife folding dies 5 are connected to each other through a hook assembly 9. The lower end of each short knife folding die 5 is first fixed to the mounting seat 6, and the lower end of the mounting seat 6 is then connected to the guide rail seat 7 to ensure that the guide rail seat 7 can slide smoothly on the linear guide rail 2. A high-precision slider and guide rail matching method can be adopted between the guide rail seat 7 and the linear guide rail 2. The slider is made of high-strength, low-friction coefficient materials, such as high-quality alloy steel, and is precision machined and heat-treated to ensure its dimensional accuracy and surface hardness, so as to achieve smooth, low-resistance sliding motion.

[0027] Platforms 8 are installed below both ends of the linear guide 2. The platform 8 is firmly connected to the frame 1 through high-strength bolts. When connecting, a suitable torque wrench should be used to tighten the bolts according to the specified torque to ensure the tightness of the connection. A horizontally placed synchronous pulley 11 is placed on the platform 8. The synchronous pulleys 11 on the platforms 8 on both sides are connected by a synchronous belt 12 to form a closed-loop transmission system. The selection of the synchronous belt 12 should take into account its transmission accuracy, load-bearing capacity and durability. For example, a high-strength polyurethane synchronous belt can be used, which has good flexibility, wear resistance and anti-aging properties. A connecting plate 13 is fixed near the inner side of the platform 8. The connecting plate 13 is tightly connected to the synchronous belt 12. At the same time, a reliable connection method is also used between the connecting plate 13 and the platform 8, such as welding or high-strength bolt connection, to ensure that the connecting plate 13 can stably transmit power during the transmission process without loosening or deformation.

[0028] The hook assembly 9 is a key component for realizing flexible connection and separation between the short knife folding molds 5. The guide seat 91 is made of high-quality steel and is precisely processed to ensure that the dimensional accuracy and surface roughness of its hook groove structure meet the requirements. Baffles 95 are installed at both ends of the guide seat 91. The connection between the baffle 95 and the guide seat 91 is detachable, and can be connected by bolts or slots. When the baffle 95 needs to be replaced to adapt to different short mold sizes, it can be operated conveniently and quickly. For example, when using bolt connections, select high-strength bolts of appropriate specifications and apply an appropriate amount of thread locking agent on the bolts to prevent the bolts from loosening during equipment operation.

[0029] A groove is provided on one side of the hook 92 to connect with the seat body of the adjacent guide seat 91, and a pin hole is provided on the other side to connect with the guide seat 91 through a cylindrical pin 97, so that the hook 92 can rotate around the cylindrical pin 97. The cylindrical pin 97 is made of high-strength alloy steel, and the surface is hardened to improve its wear resistance and shear resistance. During the installation process of the hook 92, it is necessary to ensure that it rotates flexibly without jamming. An appropriate amount of grease can be added between the pin hole and the cylindrical pin 97 to reduce friction. The spring 94 is installed in the guide seat 91, and one end of it contacts the hook 92. When the free length is reached, the hook 92 can be placed in a locking position to ensure that the connection between the adjacent short knife folding molds 5 is stable. The material selection of the spring 94 should be calculated and selected according to the actual stress conditions to ensure that it has sufficient elasticity and fatigue life. For example, it can be made of high-quality spring steel and undergo a strict heat treatment process to improve its mechanical properties. The support block 96 is placed at the rear of the guide seat 91, and its height is adjustable. The adjustment method can adopt a threaded adjustment structure to change its height by rotating the support block 96. When installing the support block 96, it is necessary to make precise adjustments according to the actual installation height of the short knife folding mold 5 so that the adjacent molds are consistent in height direction to ensure that the plate is evenly stressed during the bending process. The guide bar 93 is installed on the guide seat 91 to guide the movement of the hook 92 to ensure the stability and accuracy of the hook 92 during the rotation process. The guide bar 93 is made of wear-resistant materials, such as surface-hardened steel or high-strength engineering plastics, and its surface has a low friction coefficient, which can reduce the wear of the hook 92 during movement.

[0030] The latch device 4 includes a guide sleeve 41, a support 42, a cylinder 43 and a push rod 44. The support 42 is installed above the platform 8 near the inner side. The connection between the support 42 and the platform 8 must be firm and stable. It can be connected by welding or bolts, and reinforced to prevent the support 42 from displacement or deformation during the operation of the equipment. The guide sleeve 41 is connected to the front side of the support 42. The guide sleeve 41 is made of high-precision pipes and is processed by inner hole grinding to ensure the inner diameter size accuracy and cylindricity, providing precise guidance for the reciprocating motion of the push rod 44.

[0031] The cylinder 43 is installed on the support 42. The selection of the cylinder 43 should determine its parameters such as cylinder diameter, stroke and working pressure according to the actual work requirements. The cylinder 43 is connected to the support 42 by bolts, and a corresponding buffer device is installed to reduce the impact force of the cylinder 43 when it moves to the end of the stroke. The push rod 44 is connected to the cylinder 43 and placed on the inner side of the guide sleeve 41. The diameter of the push rod 44 matches the inner diameter of the guide sleeve 41 to ensure that it can slide smoothly in the guide sleeve 41, while having a small gap to prevent shaking. During the installation process, it is necessary to ensure that the axes of the cylinder 43, the push rod 44 and the guide sleeve 41 coincide. A special tooling fixture can be used for positioning and installation to improve the installation accuracy. After the installation is completed, the latch device 4 is debugged to check whether the movement of the cylinder 43 is smooth, whether the telescopic stroke of the push rod 44 meets the design requirements, and whether the fit between the push rod 44 and the hook 92 is accurate. By adjusting the air source pressure and flow rate of the air cylinder 43 and adjusting the position of the push rod 44, the latch device 4 can accurately realize the pushing and releasing actions of the hook 92 under the control of the numerical control system.

[0032] The servo motor 14 is installed at a suitable position on the frame 1, and its output shaft is connected to the synchronous pulley 11 through a coupling. The selection of the coupling should be based on the output torque, speed and precision requirements of the servo motor 14. For example, an elastic coupling can be selected, which can effectively compensate for the slight deviation between the motor shaft and the synchronous pulley 11 shaft, and has good shock absorption performance to ensure the smooth operation of the transmission system. When connecting the coupling, pay attention to ensuring the coaxiality of the motor shaft and the synchronous pulley 11 shaft. You can use a measuring tool such as a dial indicator to measure and adjust it so that the coaxiality error is controlled within the allowable range.

[0033] After the connection is completed, the parameters of the servo motor 14 are set and debugged. According to the process requirements of the short edge bending of the plate, the parameters such as the speed, acceleration, deceleration and torque of the servo motor 14 are set. The servo motor 14 is controlled by the numerical control system to achieve precise motion control of the synchronous belt 12 and the automatic adjustable short knife folding die set 3. During the debugging process, it is necessary to check whether the drive of the servo motor 14 is stable, whether the synchronous belt 12 slips, and whether the movement of the die set on the linear guide 2 is accurate. A high-precision position sensor can be used to monitor the position of the die set in real time, and the monitoring data can be fed back to the numerical control system. By adjusting the control parameters of the servo motor 14, the motion accuracy and stability of the die set can be continuously optimized.

[0034] Short mold length free combination action process: under the control of the CNC system, start the servo motor 14, the servo motor 14 drives the synchronous pulley 11 to rotate according to the preset program, and drives the synchronous belt 12 together with the mold assembly 3 to start moving on the linear guide 2. When the entire short side mold is required for folding, the CNC system issues a command to make the servo motor 14 drive the synchronous belt 12 to drive the short knife molds 3 at both ends to move toward the middle until all the short knife molds 5 are combined into a complete folding mold. During the movement, the position of the mold group is monitored in real time by the linear displacement sensor installed on the linear guide 2 to ensure that the mold group moves accurately to the predetermined position. The linear displacement sensor can use a high-precision grating scale or magnetic scale, and its measurement accuracy can reach the micron level, providing a reliable basis for the precise positioning of the mold group.

[0035] When a specified folding length is required, the numerical control system first calculates the distance and position that the short knife mold 5 needs to move according to the preset folding length. Then the servo motor 14 drives the short mold assembly to travel on the linear guide rail 2 to the required length position. At this time, the numerical control system controls the cylinder 43 to move, so that the cylinder 43 is ventilated, and the push rod 44 extends under the action of air pressure, pushing the hook 92 to the spring 94 compression state, and the hook 92 is separated from the adjacent short mold guide seat 91. Then the servo motor 14 drives the short mold assembly to move to the middle again, and adjusts the combined length of the mold group according to the required folding length. In this process, the numerical control system must accurately control the movement speed and position of the servo motor 14, as well as the action timing of the cylinder 43, to ensure that the entire short mold length free combination action is accurate and smooth. After the adjustment is completed, the cylinder 43 is exhausted, the push rod 44 is retracted, and the hook 92 is restored to the locking position under the action of the spring 94, and the adjacent short knife folding molds 5 are connected and fixed again, and the short side bending process of the plate is ready.

[0036] Regularly check the lubrication of the linear guide rail 2 and the guide rail seat 7, and add an appropriate amount of special guide rail lubricant to ensure smooth sliding of the guide rail and reduce wear. At the same time, check whether there is foreign matter or damage on the surface of the guide rail. If there is any foreign matter, clean it up in time. If the surface of the guide rail is found to be scratched or severely worn, it should be repaired or replaced in time to avoid affecting the motion accuracy of the mold set.

[0037] Check the synchronous belt 12 and synchronous pulley 11 regularly to see if the synchronous belt 12 is loose, worn or broken, and whether the tooth shape of the synchronous pulley 11 is intact. If the synchronous belt 12 is loose, the synchronous belt 12 can be tightened by adjusting the center distance of the synchronous pulley 11; if the synchronous belt 12 is worn or broken, it should be replaced with a new synchronous belt 12 of the same specification in time. When the tooth shape of the synchronous pulley 11 is damaged, it also needs to be replaced in time to ensure the accuracy and stability of the transmission.

[0038] Check the working conditions of the cylinder 43, guide sleeve 41 and push rod 44 in the latch device 4. Ensure that the sealing performance of the cylinder 43 is good and there is no air leakage. If the seal of the cylinder 43 is found to be aged or damaged, it should be replaced in time. Clean the inside of the guide sleeve 41 regularly to prevent dust and other impurities from entering and affecting the movement of the push rod 44. At the same time, check whether the surface of the push rod 44 is scratched or worn. If necessary, repair or replace the push rod 44.

[0039] Check and maintain each component in the hook assembly 9. Check the rotation flexibility of the hook 92. If there is any jamming, clean the debris between the hook 92 and the guide seat 91 and add an appropriate amount of grease. Check whether the elasticity of the spring 94 is normal. If the spring 94 is fatigued or damaged, it should be replaced in time. Regularly check whether the connection between the baffle 95 and the support block 96 is firm. If it is loose, tighten it in time. At the same time, check the wear of the guide bar 93. If the wear seriously affects the guiding accuracy of the hook 92, the guide bar 93 should be replaced.

[0040] Check the heat dissipation of the servo motor 14 regularly to ensure that the area around the motor is well ventilated and that there is no debris that would affect the heat dissipation. Check whether the electrical connection of the motor is loose and clean the motor regularly to prevent dust and oil from entering the motor and affecting its performance. At the same time, lubricate and maintain the motor bearings regularly in accordance with the motor maintenance manual to extend the motor's service life.
