Description

Technical Field

[0001] The invention belongs to the technical field of drawer slide rail processing, and in particular relates to a method for processing a drawer slide rail. Background Art

[0002] Drawer slides are a type of hardware used to connect drawers and cabinets. Their main function is to guide the drawer to move smoothly and steadily during the pulling process, while bearing the weight of the drawer. Drawer slides are widely used in furniture, office equipment and other fields, which not only improves the service life of the drawer, but also greatly enhances the user experience.

[0003] Drawer slides are mainly assembled by sliding multiple sets of guide rails. The guide rails are first formed into a long rectangular structure with an opening by a metal plate through a bending process. Then, a stamping mechanism is used to punch holes and shapes at both ends of the guide rails for subsequent assembly and fixation. At present, when the drawer slides are stamped, in order to ensure the degree of automation and smoothness of the processing, a number of card slots are generally set on the fixed frame of the processing machine. Then, a conveying mechanism is used to convey the guide rails from one end of the fixed frame to the other end in a step-by-step motion, so that the guide rails pass through the stamping mechanism in turn. In this process, every time the guide rail moves a small step, it will be stuck in the corresponding card slot on the fixed frame, and the outer wall of the guide rail is limited by the inner wall of the card slot, thereby ensuring that the guide rail can cooperate with the stamping mechanism during stamping, and better complete the stamping process of the drawer slides.

[0004] However, there are some problems in the processing of drawer slides at present: since a large number of guide rails need to be repeatedly processed in actual processing, as the number of guide rail processing increases, the contact frequency between the card slot of the fixed frame and the guide rail increases, which will cause wear or deformation of the inner wall of the card slot, and its size change, resulting in a decrease in the matching accuracy between the card slot and the guide rail. During the stamping process, this mismatch will cause the guide rail to fail to move accurately along the predetermined trajectory, causing position deviation between the guide rail and the stamping mechanism, thereby resulting in uneven distribution of stamping force, affecting the stamping processing accuracy of the guide rail. In this regard, a processing method for drawer slides is proposed. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, the present invention provides a method for processing a drawer slide rail, which solves the problem in the prior art that the fit between the slot and the guide rail decreases, resulting in the guide rail being unable to move accurately along the predetermined trajectory, thereby causing uneven punching force distribution.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A method for processing a drawer slide rail comprises the following steps:

[0008] S1: Guide rail placement: a number of slots are evenly spaced on the fixed frame of the processing machine, and anti-loosening components are set in the slots to prevent the guide rail from losing its fit with the slots. A number of punching machines are set on both sides of the fixed frame, and the guide rail is placed on the fixed frame. The guide rail is moved from one end of the fixed frame to the other end in a step-by-step manner through a conveying mechanism to ensure that the guide rail is stuck in the corresponding slot on the fixed frame every time it moves a small step.

[0009] S2: stamping processing. In S1, the conveying mechanism conveys the guide rail from one end of the fixed frame to the other end in a step motion. When the guide rail moves to the punching machine on one side of the fixed frame, the pushing mechanism pushes one end of the guide rail to the bottom of the punching head of the punching machine, and the punching head punches one end of the guide rail to form the required shape and size.

[0010] S3: The guide rail is reset by the pushing mechanism, and then the guide rail is moved forward in a step-by-step motion by the conveying mechanism. When the guide rail moves to the punching machine on the other side of the fixed frame, the other end of the guide rail is pushed under the punching head of the punching machine by the pushing mechanism, and the other end of the guide rail is punched by the punching head to form the required shape and size;

[0011] S4: The guide rail is reset by the pushing mechanism, and then the guide rail is flipped 90° by the flipping mechanism, and S2-S3 are repeated to punch both ends of the guide rail again to form the required shape and size;

[0012] S5: Use the push mechanism to push out the processed guide rail to prepare for the next processing.

[0013] As a further solution of the present invention, when the guide rail is punched by the punch head, the following steps are adopted:

[0014] S21: Slightly pre-press the guide rail to eliminate stress inside the material;

[0015] S22: Start to apply lower pressure to gradually deform the material;

[0016] S23: gradually increase the pressure to ensure uniform deformation;

[0017] S24: Continue to apply pressure until the desired degree of deformation is achieved.

[0018] As a further solution of the present invention, the punching head is provided with a pressure sensor for real-time measurement of the punching force and a displacement sensor for real-time monitoring of the punching head. The punching machine is externally connected to a control system, and the pressure sensor and the displacement sensor are respectively communicatively connected to a control terminal of the external control system; the control terminal is also preset with pressure distribution target parameters, and the pressure sensor and the displacement sensor upload the collected data to the control terminal. The control terminal performs real-time analysis on the collected pressure and displacement data through a data analysis module, and draws a pressure-displacement curve. The pressure data applied by the punching head to the guide rail is fed back to the control terminal, and the control terminal compares and analyzes the obtained data with the pressure-displacement curve, and then the control terminal automatically adjusts the pressure distribution in the system to ensure uniform pressure distribution.

[0019] As a further solution of the present invention, the anti-loosening component includes a first sliding part slidably arranged in the slot, a second sliding part slidably arranged on the fixed frame, and a spring rotating part rotatably arranged on the fixed frame. The first sliding part and the second sliding part are connected by the spring rotating part. A limiting groove is arranged on the first sliding part. The guide rail is clamped in the limiting groove. The pushing mechanism pushes the guide rail to move. The guide rail drives the first sliding part to slide. The first sliding part drives the spring rotating part to rotate. The spring rotating part drives the second sliding part to slide. The first sliding part is locked with the spring rotating part to make the guide rail move along a predetermined trajectory.

[0020] As a further solution of the present invention, a flexible buffer pad is provided on the side wall of the limiting groove, and the guide rail is in contact with the flexible buffer pad.

[0021] As a further solution of the present invention, the number of the spring rotating parts and the second sliding parts are both two, and the spring rotating parts and the second sliding parts are symmetrically distributed on both sides of the first sliding part.

[0022] As a further solution of the present invention, the spring rotating part includes a rotating rod rotatably arranged on a fixed frame and a first spring, and two ends of the first spring are respectively connected to the rotating rod and the second sliding part.

[0023] As a further solution of the present invention, the first sliding part is a first slider, the first slider matches the slot, two grooves are arranged on the same side of the first slider, and the rotating rod is respectively provided with blocks matching the two grooves. The first slider is connected to the bottom of the slot by a second spring, and the first slider drives the rotating rod to rotate so that the two blocks on the rotating rod are respectively engaged with the two grooves.

[0024] As a further solution of the present invention, the side of the two card blocks that are close to each other is a horizontal structure, the side of the two card blocks that are away from each other is an arc structure, and the connection between the horizontal structure and the arc structure is an arc structure.

[0025] As a further solution of the present invention, the second sliding part includes a guide rail arranged on the fixing frame and a second sliding block slidably arranged on the guide rail, and the second sliding block is vertically arranged between the second spring.

[0026] The beneficial effects of the present invention are:

[0027] By arranging an anti-loosening component on the fixed frame, the fit between the guide rail and the card slot can be prevented from decreasing after long-term use, ensuring that the guide rail can accurately move along the predetermined track. When the guide rail moves to the punching machine on one side of the fixed frame, the pushing mechanism pushes one end of the guide rail to push the guide rail under the punching head of the punching machine, and the punching head punches one end of the guide rail to form the required shape and size; the pushing mechanism resets the guide rail, and then the conveying mechanism conveys the guide rail forward in a step-by-step motion. When the guide rail moves to the punching machine on the other side of the fixed frame, , the other end of the guide rail is pushed by the pushing mechanism to push the guide rail under the punching head of the punching machine, and the other end of the guide rail is punched by the punching head to form the required shape and size, the guide rail is reset by the pushing mechanism, and then the guide rail is flipped 90° by the flipping mechanism, and S2-S3 are repeated, and the two ends of the guide rail are punched again to form the required shape and size, thereby effectively solving the problems of reduced fit between the card slot and the guide rail and uneven distribution of punching force in the prior art, and improving the processing quality and efficiency, ensuring the quality consistency of the drawer slide processing.

DETAILED DESCRIPTION

[0036] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0037] See also Figure 1 - Figure 5 , this embodiment provides a method for processing a drawer slide rail, comprising the following steps:

[0038] S1: guide rail 7 is placed, a number of slots are arranged at equal intervals on the fixed frame 1 of the processing machine, and anti-loosening components 8 are arranged in the slots to prevent the guide rail 7 from decreasing the degree of fit between the slots. A number of punching machines 2 are arranged on both sides of the fixed frame 1, and the guide rail 7 is placed on the fixed frame 1. The guide rail 7 is transported from one end of the fixed frame 1 to the other end in a step-by-step manner through the conveying mechanism 3, ensuring that the guide rail 7 is stuck in the corresponding slot on the fixed frame 1 every time it moves a small step; wherein the anti-loosening component 8 can effectively prevent the guide rail 7 from decreasing the degree of fit due to vibration or wear during use, thereby ensuring the close fit between the guide rail 7 and the slots, and the slots are arranged at equal intervals, so that the guide rail 7 can be accurately inserted into the corresponding slot during each conveying process, thereby avoiding track deviation due to decreased fit;

[0039] S2: stamping processing. In S1, the conveying mechanism 3 conveys the guide rail 7 from one end of the fixed frame 1 to the other end in a step motion. When the guide rail 7 moves to the punching machine 2 on one side of the fixed frame 1, the pushing mechanism 4 pushes one end of the guide rail 7 to the bottom of the punching head of the punching machine 2, and the punching head punches one end of the guide rail 7 to form the required shape and size.

[0040] S3: The guide rail 7 is reset by the pushing mechanism 4, and then the guide rail 7 is moved forward in a step-by-step manner by the conveying mechanism 3. When the guide rail 7 moves to the punching machine 2 on the other side of the fixed frame 1, the other end of the guide rail 7 is pushed by the pushing mechanism 4 to push the guide rail 7 under the punching head of the punching machine 2, and the other end of the guide rail 7 is punched by the punching head to form the required shape and size;

[0041] S4: reset the guide rail 7 by pushing the mechanism 4, then flip the guide rail 7 90° by flipping the mechanism 5, repeat S2-S3, and punch the two ends of the guide rail 7 again to form the required shape and size; by punching the two ends of the guide rail 7 in steps, the uniform distribution of the punching force on the guide rail 7 is ensured, and each step of punching can evenly apply pressure within a smaller range, avoiding deformation or damage caused by excessive local pressure, and by automatically resetting and flipping the mechanism 5, uniform punching of the two ends of the guide rail 7 and in different directions is achieved, ensuring that the shape and size of the entire guide rail 7 meet the requirements; in addition, the setting of the flipping mechanism 5 and the punching machine 2 enables the guide rail 7 to be punched in different directions to meet the processing requirements of different shapes and sizes;

[0042] S5: Use the push mechanism 6 to push out the processed guide rail 7 to prepare for the next processing;

[0043] It should be noted that the above-mentioned pushing mechanism 4, conveying mechanism 3, turning mechanism 5 and pushing mechanism 6 are all automated mechanisms used on the processing machine when processing the drawer slide rail. Figure 2 As shown, these mechanisms only need to be able to realize the functions of pushing, conveying, flipping and pushing materials. For this, the structures of these mechanisms will not be described in detail here.

[0044] At present, when processing drawer slides, some of them are provided with a plurality of slots on the fixed frame 1 of the processing machine, and then the conveying mechanism 3 is used to convey the guide rail 7 from one end of the fixed frame 1 to the other end in a step-by-step motion so that it passes through the punching machine 2. In this process, every time the guide rail 7 moves a small step, it will be stuck in the corresponding slot on the fixed frame 1, thereby ensuring that the guide rail 7 can cooperate with the punching machine 2 during stamping to better complete the processing of the drawer slides. There are some problems in the processing of the drawer slides described above. For example, since a large number of guide rails 7 need to be repeatedly operated during actual processing, with the passage of time, the materials of the fixed frame 1 and the guide rail 7 will change size due to wear or deformation, resulting in a decrease in the fit between the slot and the guide rail 7. During the stamping process, this mismatch will cause the guide rail 7 to fail to move accurately along the predetermined trajectory, thereby causing uneven distribution of the stamping force.

[0045] In order to solve the above problem, in this embodiment, by arranging an anti-loosening component 8 on the fixed frame 1, it is possible to prevent the fit between the guide rail 7 and the card slot from decreasing after long-term use, thereby ensuring that the guide rail 7 can accurately move along the predetermined trajectory. When the guide rail 7 moves to the punching machine 2 on one side of the fixed frame 1, the pushing mechanism 4 pushes one end of the guide rail 7 to push the guide rail 7 under the punching head of the punching machine 2, and the punching head punches one end of the guide rail 7 to form the required shape and size; the pushing mechanism 4 resets the guide rail 7, and then the conveying mechanism 3 conveys the guide rail 7 forward in a step-by-step motion. When the guide rail 7 moves to the punching machine 2 on the other side of the fixed frame 1, the other end of the guide rail 7 is pushed by the pushing mechanism 4 to push the guide rail 7 under the punching head of the punching machine 2, and the other end of the guide rail 7 is punched by the punching head to form the required shape and size. The guide rail 7 is reset by the pushing mechanism 4, and then the guide rail 7 is flipped 90° by the flipping mechanism 5, and S2-S3 are repeated, and the two ends of the guide rail 7 are punched again to form the required shape and size, thereby effectively solving the problems of reduced fit between the slot and the guide rail 7 and uneven distribution of punching force in the prior art, and improving the processing quality and efficiency.

[0046] During the processing of the drawer slide rail, improper stamping methods may easily lead to uneven distribution of stamping force. In this regard, in one embodiment, when the guide rail 7 is stamped by a stamping head, the following steps are adopted:

[0047] S21: Slightly pre-pressing the guide rail 7 to eliminate stress inside the material; pre-pressing can eliminate residual stress inside the material, prevent deformation or dimensional instability caused by stress release during subsequent processing, avoid processing deformation caused by stress release, and ensure dimensional accuracy and shape stability of the guide rail 7;

[0048] S22: Start to apply lower pressure to gradually deform the material. Starting processing with lower pressure allows the material to gradually adapt to the external force, avoiding material damage or rupture caused by sudden excessive pressure, reducing the risk of material damage during processing, and improving material utilization.

[0049] S23: gradually increase the pressure to ensure uniform deformation; gradually increasing the pressure can make the material deform evenly, avoid local overload or insufficient deformation, ensure the deformation quality of the entire guide rail 7, avoid excessive or insufficient local deformation, and ensure the consistency and service life of the product;

[0050] S24: Continue to apply pressure until the desired degree of deformation is reached. By continuing to apply pressure until the desired degree of deformation is reached, it can be ensured that the product meets the predetermined performance requirements.

[0051] It should be added that, in addition to adopting a step-by-step method during stamping to avoid uneven distribution of stamping force, since the speed of the stamping head and the pressure provided are different during each step of operation, and in the actual production of drawer slides, the method of the present application is adopted. Figure 2 When the equipment in the punching machine performs punching, the punching speed is relatively fast. In this case, the size of the punching force is more difficult to monitor in real time, and it is still possible to cause uneven distribution of the punching force. In this regard, in one embodiment, a pressure sensor for real-time measurement of the punching force and a displacement sensor for real-time monitoring of the punching head are provided on the punching head. The punching machine 2 is externally connected to the control system, and the pressure sensor and the displacement sensor are respectively connected to the control terminal of the external control system for communication; the control terminal is also preset with pressure distribution target parameters, and the pressure sensor and the displacement sensor upload the collected data to the control terminal. The control terminal analyzes the collected pressure and displacement data in real time through the data analysis module, and draws a pressure-displacement curve. The pressure data applied by the punching head to the guide rail 7 is fed back to the control terminal, and the control terminal compares and analyzes the obtained data with the pressure-displacement curve, and then the control terminal automatically adjusts the pressure distribution in the system to ensure uniform pressure distribution;

[0052] In view of the difficulty in real-time monitoring of the punching force due to the different speeds and pressures of the punching head and the fast punching speed during the stamping process, and the possible problem of uneven pressure distribution, a pressure sensor and a displacement sensor are installed on the punching head to measure the punching force and the displacement of the punching head in real time. The punching machine 2 is connected to an external control system, and the pressure sensor and the displacement sensor are communicated with the control terminal of the control system. The target parameters of the pressure distribution are preset in the control terminal. The pressure sensor and the displacement sensor upload the collected data to the control terminal. The control terminal analyzes the data through a data analysis module and draws a pressure-displacement curve. The control terminal compares and analyzes the real-time collected pressure data with the pressure-displacement curve. The control terminal automatically adjusts the pressure distribution in the system according to the analysis results to ensure that the punching force is evenly distributed. Through real-time monitoring and automatic adjustment, the punching force is evenly distributed throughout the stamping process, thereby improving the quality of the stamped parts. The uniform pressure distribution reduces the deformation or damage of the stamped parts caused by uneven pressure, thereby reducing the scrap rate.

[0053] It is worth mentioning that, during processing, the guide rail 7 needs to move longitudinally, that is, move forward, and also needs to move laterally, so as to process both ends, and when the guide rail 7 moves laterally, it needs to be punched. At this time, the guide rail 7 needs to be moved along the slot to the bottom of the punching head first. However, after a large number of repeated operations, the friction between the guide rail 7 and the slot may cause the matching accuracy between the guide rail 7 and the slot to decrease. The anti-loosening component 8 is used to solve this problem. Here, in order to ensure that the guide rail 7 is locked and will not continue to slide after it moves to the bottom of the punching head, even if the friction between the guide rail 7 and the slot may cause the matching accuracy between the guide rail 7 and the slot to decrease, it can also ensure that the guide rail 7 will not continue to slide. In this regard, in one embodiment, the anti-loosening component 8 includes a first sliding portion 81 slidably arranged in the slot, a sliding portion 81 arranged The second sliding part 83 on the fixed frame 1 and the spring rotating part 82 rotatably arranged on the fixed frame 1, the first sliding part 81 and the second sliding part 83 are connected through the spring rotating part 82, a limiting groove is arranged on the first sliding part 81, the guide rail 7 is clamped in the limiting groove, the pushing mechanism 4 pushes the guide rail 7 to move, the guide rail 7 drives the first sliding part 81 to slide, the first sliding part 81 drives the spring rotating part 82 to rotate, the spring rotating part 82 drives the second sliding part 83 to slide, the first sliding part 81 and the spring rotating part 82 are locked, so that the guide rail 7 moves along the predetermined trajectory, wherein the locking between the first sliding part 81 and the spring rotating part 82 is in a stuck state, which can ensure that the guide rail 7 moves along the predetermined trajectory, and the friction between the guide rail 7 and the clamping groove may cause the guide rail 7 to continue to move, such as Figure 3 and Figure 4 shown.

[0054] In addition, the side wall of the limiting groove is provided with a flexible buffer pad, and the guide rail 7 fits with the flexible buffer pad; the flexible buffer pad on the side wall of the limiting groove can reduce the impact and noise when the guide rail 7 moves, and at the same time extend the service life of the component, the number of the spring rotating part 82 and the second sliding part 83 are both two, and the spring rotating part 82 and the second sliding part 83 are symmetrically distributed on both sides of the first sliding part 81; the spring rotating part 82 and the second sliding part 83 are symmetrically distributed on both sides of the first sliding part 81, this design helps to balance the force and reduce the structural deformation and wear caused by uneven force on one side; the spring rotating part 82 includes a rotating rod 821 and a first spring 822 rotatably arranged on the fixed frame 1, and the two ends of the first spring 822 are respectively connected to the rotating rod 821 and the second sliding part 83; the first sliding part 81 is connected to the rotating rod 821 through the first spring 822, allowing a certain degree of elastic deformation, which helps to absorb external impact force and improve the component's resistance to vibration. The design of the groove 811 on the first slider and the block on the rotating rod 821 allows the movement trajectory of the component to be accurately controlled.

[0055] In order to make the anti-loosening component 8 move better, in one embodiment, the first sliding part 81 is a first slider, the first slider matches the card slot, two grooves 811 are arranged on the same side of the first slider, and the rotating rod 821 is respectively provided with a card block matching the two grooves 811, and the first slider is connected to the bottom of the card slot through a second spring 812. The function of the second spring 812 is to ensure that the guide rail 7 can be locked and can also be better reset with the pushing mechanism 4 after the movable cabinet moves horizontally and after stamping, so as to facilitate longitudinal movement. In addition, the existence of the second spring 812 can also absorb the vibration generated during stamping, so that the impact force is more uniform. The first slider drives the rotating rod 821 to rotate, so that the two blocks on the rotating rod 821 are respectively engaged with the two grooves 811, the side of the two blocks close to each other is a horizontal structure, the side of the two blocks away from each other is an arc structure, and the connection between the horizontal structure and the arc structure is an arc structure; the design here can ensure that the two blocks can not only lock the first slider and the guide rail 7, but also ensure that the guide rail 7 will not be interfered when it is reset. In addition, the second sliding part 83 includes a guide rail 831 set on the fixing frame 1 and a second slider 832 slidably set on the guide rail 831, and the second slider 832 is vertically arranged between the second spring 812;

[0056] In addition, it should be noted that precise motion control can be achieved through the cooperation between the sliding part and the rotating rod 821. The cooperation between the first slider and the block of the rotating rod 821 can ensure the synchronization and accuracy of the movement. The first slider is connected to the bottom of the slot through the second spring 812, which can buffer and disperse the force during movement and reduce the impact and wear on the structure. The horizontal structure and arc structure design between the two blocks, as well as the connection of the arc structure, help to reduce the size of the entire device and make it more compact. The design of the slot and block that cooperate with each other improves the stability and reliability of the structure and reduces errors in movement.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
