Description

Technical Field

[0001] The utility model relates to the technical field of drawer slide rail processing equipment, in particular to a stamping device for a movable rail of a riding drawer. Background Art

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

[0003] As a new type of drawer slide, the saddle drawer, such as the Chinese utility model patent publication number CN208972967U, a push-type drawer slide, discloses how the saddle drawer is assembled with the drawer. Due to its structural design, which is different from traditional slides, the drawer is more tightly closed, the gap between the drawer and the cabinet is reduced, and the overall aesthetics are improved. Due to the saddle drawer's L-shaped structure, the load-bearing capacity is significantly improved compared to ordinary slides, making it widely popular in the market. As consumers' requirements for home quality continue to increase, the market demand for saddle drawers will continue to grow.

[0004] The movable rail of a saddle drawer is a long, rectangular structure with an opening formed by bending sheet metal. Based on this structure, both ends of the movable rail need to be stamped to achieve assembly and connection with parts such as the fixed rail, damper, and guide profile. The specific processing content includes punching a hook at one end of the back of the movable rail opening and punching a hole at the other end. Then, the movable rail needs to be flipped 90 degrees and punched at both ends. Currently, the movable rail has a complex structure and the stamping process involves four steps. It also requires flipping, which makes the processing difficult. Therefore, the existing technology uses manual stamping to perform each step one by one. However, the manual loading and unloading processing method has a low degree of automation, is not only time-consuming and inefficient, but also difficult to connect with other automated links in the movable rail production line. Secondly, the processing quality stability and consistency during manual operation are poor. Due to fatigue and lack of concentration, it is easy to cause missed processing, which affects product quality. In addition, due to the open design of the movable rail, there is a risk of scratches from the opening edge during manual loading and unloading, increasing the probability of industrial accidents.

[0036] Example: Figure 1-10 As shown, a stamping device for a saddle-drawer movable rail comprises a machine base 1, a flipping mechanism 2, and a pushing mechanism 3. The machine base 1 is equipped with a conveying mechanism 4 for conveying the movable rail and a punching mechanism 5 for punching the movable rail. The punching mechanism 5 is provided with multiple groups, and the multiple groups of punching mechanisms 5 are arranged on both sides of the conveying mechanism 4 in the lateral direction and alternately arranged along the longitudinal direction of the conveying mechanism 4. The conveying mechanism 4 comprises a fixed frame 401 and a longitudinal moving frame 402. The fixed frame 401 is assembled on the machine base 1 and is used to place the movable rail. The longitudinal moving frame 402 is movably assembled with the machine base 1 and is used to convey the movable rail on the fixed frame 401. The flipping mechanism 2 is assembled on the side wall of the fixed frame 401 and is used to flip the movable rail. The pushing mechanism 3 and the punching mechanism 5 are arranged opposite to each other along the lateral direction of the machine base 1 and assembled on the side wall of the fixed frame 401.

[0037] During processing, the bent movable rail is placed on the fixed frame 401, and the longitudinal moving frame 402 is lifted-longitudinally moved-lowered-longitudinally moved, thereby driving the movable rail on the fixed frame 401 to move longitudinally. Since the stamping mechanism 5 is arranged on both sides of the fixed frame 401 and is alternately arranged along the longitudinal direction of the fixed frame 401, it is used to perform punching and perforation settings on both ends of the movable rail. Specifically, the punch 504 and the die 503 of the stamping mechanism 5 are adjusted to adapt to the punching and perforation processing of the movable rail. When the longitudinal moving frame 402 transports the movable rail between the stamping mechanism 5 and the pushing mechanism 3, the pushing mechanism 3 pushes the movable rail of the fixed frame 401. The mold 503 moves toward the stamping mechanism 5, and the punch 504 of the stamping mechanism 5 presses down to complete the stamping process on one end of the movable rail. Then, the movable rail is pushed to be placed on the fixed frame 401. Then, the longitudinal moving frame 402 drives the movable rail to move longitudinally in sequence, and the other end of the movable rail is punched. Then, the longitudinal moving frame 402 drives the movable rail to move longitudinally in sequence, and the flipping mechanism 2 flips the movable rail 90°. Then, the longitudinal moving frame 402 drives the movable rail to move longitudinally in sequence, and stamps one end of the movable rail. Then, the longitudinal moving frame 402 drives the movable rail to move longitudinally in sequence, and stamps the other end of the movable rail.

[0038] It is worth mentioning that there are four groups of punching mechanisms 5 .

[0039] By arranging the conveying mechanism 4, the turning mechanism 2 and the multiple sets of stamping mechanisms 5 in an alternating manner, the problem of punching the shapes and holes at both ends of the movable rail is solved, and the manual loading and unloading for stamping processing is replaced, which reduces the labor intensity, improves the continuity of the stamping processing of the movable rail, improves the production speed, reduces the processing cycle, and improves the overall production automation level of the movable rail, which is conducive to the automated parallelization with the previous and next processes; secondly, a one-flow production method is adopted to reduce the risk of missed processing of the movable rail and improve the consistency and stability of the processing quality of the movable rail; in addition, the movable rail is conveyed by the longitudinal frame 402, which reduces the frequency or probability of the operator contacting the movable rail and reduces the risk of the operator being scratched by the opening of the movable rail. During stamping, the pushing mechanism 3 is used to push, which reduces the risk of direct contact between the operator and the stamping mechanism 5, improves the safety of the stamping processing of the movable rail, and reduces the probability of work-related injuries.

[0040] Since the movable rail is in the shape of a rectangular parallelepiped, it is easy to deviate when placed directly on the fixed frame 401, thereby affecting the stamping accuracy of the movable rail by the stamping mechanism 5, especially in the process of the longitudinal moving frame 402 transporting the movable rail on the fixed frame 401. In order to solve the above technical problems, the top wall of the fixed frame 401 is provided with multiple groups of first U-shaped grooves 4011 that are compatible with the shape of the movable rail, and the fixed frame 401 is provided with two groups and is respectively located at the two ends of the movable rail. The two ends of the movable rail are respectively located in the first U-shaped grooves 4011 of the two groups of fixed frames 401, and the top wall of the longitudinal moving frame 402 is provided with multiple groups of second U-shaped grooves 4021 that are compatible with the shape of the movable rail. The longitudinal moving frame 402 is provided with two groups and is located between the two groups of fixed frames 401. When the longitudinal moving frame 402 transports the movable rail of the fixed frame 401, the movable rail is located in the second U-shaped groove 4021. The movable rail is transported between the two adjacent groups of first U-shaped grooves 4011 through the transfer of the longitudinal moving frame 402. The multiple groups of first U-shaped grooves 4011 opened on the top wall of the fixed frame 401 improve the stability of the movable rail placed on the fixed frame 401, solve the problem of the movable rail placement offset, improve the stamping accuracy, and reduce the stamping error. By providing the second U-shaped groove 4021, the stability and accuracy of the movable rail transported by the longitudinal moving frame 402 are improved.

[0041] In terms of the specific structure of the longitudinal moving frame 402 transferring the movable rail, the conveying mechanism 4 also includes a transmission member 403, a connecting member 404, a lifting cylinder 405, and a longitudinal pushing cylinder 406. The transmission member 403 is slidably assembled on the inner wall of the fixed frame 401 and slides along the longitudinal direction of the fixed frame 401. The longitudinal moving frame 402 is assembled with the transmission member 403 and slides vertically along the transmission member 403. The connecting member 404 is assembled with the transmission member 403 and is located between the transmission member 403 and the longitudinal moving frame 402. The fixed end of the lifting cylinder 405 is connected to the connecting member 404. The lifting cylinder 405 is assembled with the connecting member 404 and is used to push the longitudinal moving frame 402 up and down. The fixed end of the lifting cylinder 405 is connected to the connecting member 404. The pushing force of the lifting cylinder 405 The end is connected to the bottom wall of the longitudinal moving frame 402, and the longitudinal pushing cylinder 406 is connected to the machine base 1 and is used to push the longitudinal moving frame 402 to move longitudinally along the machine base 1. It is worth mentioning that the transmission member 403 and the fixed frame 401 are longitudinally slidably assembled through the slide rail slider, and the longitudinal moving frame 402 and the transmission member 403 are vertically slidably assembled through the slide rail slider. The connecting member 404 is L-shaped. Through the coordinated work of the transmission member 403, the connecting member 404, the lifting cylinder 405 and the longitudinal pushing cylinder 406, the longitudinal moving frame 402 is pushed longitudinally by the longitudinal pushing cylinder 406, and the lifting cylinder 405 pushes the longitudinal moving frame 402 to be lifted, thereby completing the lifting-longitudinal movement-lowering-longitudinal movement of the longitudinal moving frame 402, improving the degree of automation of the handling of the movable rail, and improving production efficiency.

[0042] In terms of the specific structure of the longitudinal push cylinder 406 pushing the longitudinal movement of the longitudinal frame 402, the conveying mechanism 4 also includes a support member 407, one end of the support member 407 is connected to the transmission member 403, and the other end of the support member 407 is slidably assembled with the machine base 1 through a slide rail slider and slides along the longitudinal direction of the machine base 1. The fixed end of the longitudinal push cylinder 406 is connected to the machine base 1, and the movable end of the longitudinal push cylinder 406 is connected to the side wall of the support member 407. The longitudinal push cylinder 406 pushes the support member 407 to slide along the longitudinal direction of the machine base 1, thereby pushing the transmission member 403 to slide longitudinally. Since the longitudinal frame 402 is vertically slidably assembled with the transmission member 403, the longitudinal frame 402 slides longitudinally, and at the same time, the lifting cylinder 405 follows to slide longitudinally, and the push rod of the lifting cylinder 405 is extended and retracted to complete the lifting and lowering action of the longitudinal frame 402.

[0043] Furthermore, in order to improve the conveying accuracy of the movable rail of the conveying mechanism 4, multiple groups of first U-shaped grooves 4011 are arranged at equal intervals along the longitudinal direction of the fixed frame 401, and the spacing between two adjacent groups of first U-shaped grooves 4011 is L1. Multiple groups of second U-shaped grooves 4021 are arranged at equal intervals, and the spacing between two adjacent groups of second U-shaped grooves 4021 is L2. The longitudinal moving distance of the longitudinal moving frame 402 is L3, L3=L2=L1, so that the movable rails move synchronously and equidistantly on the fixed frame 401, reducing the risk of misalignment of the movable rails during conveying, improving the alignment accuracy of the conveying mechanism 4, and reducing the positioning error during the stamping process.

[0044] Since the movable rail is set above the two sets of fixed frames 401 and the two sets of longitudinal moving frames 402, when the pushing mechanism 3 pushes the movable rail, one end of the movable rail loses the support of the fixed frame 401 and / or the longitudinal moving frame 402, which is easy to cause it to tilt and fall. In order to ensure the stability of the pushing mechanism 3 when pushing the movable rail to the stamping mechanism 5 for stamping, in terms of the specific structure of the pushing mechanism 3, the pushing mechanism 3 includes a pushing cylinder 301, a pushing block 302, and a first mounting seat 303. The first mounting seat 303 is connected to the side wall of the fixed frame 401. The cylinder 301 is assembled on the first mounting seat 303 and is used to push the push block 302 to move back and forth along the horizontal direction of the first U-shaped groove 4011. The first U-shaped groove 4011 corresponding to the first mounting seat 303 is recessed along its longitudinal side wall to provide a third U-shaped groove for the push block 302 to slide. The second U-shaped groove 4021 corresponding to the first mounting seat 303 is recessed along its longitudinal side wall to provide a fourth U-shaped groove for the push block 302 to slide. The top wall of the push block 302 is provided with a fifth U-shaped groove 3021 that is compatible with the first U-shaped groove 4011. When the pushing cylinder 301 is in the reset state, the pushing block 302 is located in the third U-shaped groove, and the longitudinal moving frame 402 transports the movement of the fixed frame 401. When it is transported to the first U-shaped groove 4011 corresponding to the stamping mechanism 5, one end of the movable rail is located in the first U-shaped groove 4011, and the other end of the movable rail is located in the fifth U-shaped groove 3021. Since the fifth U-shaped groove 3021 is adapted to the first U-shaped groove 4011, the movable rail can be stably supported. During the stamping process, the pushing cylinder 301 pushes the pushing block 302 in The third U-shaped groove slides with the fourth U-shaped groove, and the third U-shaped groove and the fourth U-shaped groove play a supporting and limiting role on the push block 302, ensuring that the push block 302 moves longitudinally along the first U-shaped groove 4011. It is worth mentioning that the transverse axis of the third U-shaped groove and the transverse axis of the fourth U-shaped groove are both colinearly arranged with the transverse axis of the first U-shaped groove 4011 corresponding to the stamping mechanism 5, thereby improving the pushing accuracy of the pushing mechanism 3. After the pushing mechanism 3 pushes the movable rail into the mold 503 of the stamping mechanism 5, the stamping mechanism 5 performs corresponding stamping processing on it.

[0045] Since one end of the movable rail is mounted in the fifth U-shaped groove 3021 and is placed movably, when the movable rail is stamped after the movable rail is stamped, the push block 302 pulls out the movable rail, and the movable rail is easy to slip on the push block 302, which causes the position of the stamped movable rail to deviate when it returns to the fixed frame 401 again, thereby affecting the processing accuracy. In order to solve the above technical problems, in terms of the specific structure of the stamping mechanism 5, the stamping mechanism 5 includes a return cylinder 501, a punching machine 502, a mold 503 assembled with the base of the punching machine 502, and a punch 504 assembled with the oil cylinder of the punching machine 502. The mold 503 is horizontally provided with a guide groove 503 that matches the shape of the movable rail. 1. The transverse axis of the guide groove 5031 is colinear with the transverse axis of the fifth U-shaped groove 3021. The pushing cylinder 301 is assembled with the punching machine 502. The pushing cylinder 301 is located at the end of the guide groove 5031 away from the movable rail, and the pushing end of the ejecting cylinder 501 moves back and forth along the axis of the guide groove 5031, thereby pushing out the movable rail after stamping on the mold 503, and cooperating with the pushing block 302 to tighten the two ends of the limiting movable rail, thereby re-placing the movable rail on the fixed frame 401, improving the accuracy of placing the movable rail on the fixed frame 401, and reducing the risk of the movable rail being offset during the process of the pushing mechanism 3 transporting the movable rail after stamping.

[0046] It is worth mentioning that the punching machine 502, the die 503, and the punch 504 are all existing technologies. As long as they can meet the requirements of punching the two ends of the movable rail, they will not be described in detail in this embodiment.

[0047] Furthermore, since the mold 503 is provided with a guide groove 5031, in order to be able to provide a certain support to the hollow movable rail during the stamping process, the movable end shaft of the material-removing cylinder 501 is connected to a material-removing piece, and the material-pushing piece is arranged in a stepped shape. The end of the material-removing piece close to the movable rail is adapted to the inner wall of the movable rail. The end of the material-removing piece close to the material-removing cylinder 501 is larger than the outer wall of the movable rail and less than or equal to the inner wall of the guide groove 5031. When the stamping mechanism 5 is stamping, one end of the stepped material-pushing piece is inserted into the movable rail, which supports and limits the movable rail. After the stamping is completed, the material-removing cylinder 501 pushes the movable rail to move, and the stepped material-pushing piece abuts against the wall thickness of the movable rail, thereby pushing it out of the mold 503.

[0048] Since the movable rail is mounted on the inner wall of the first U-shaped groove 4011 adapted to it, if the rotating motor 201 is used to directly rotate the movable rail mounted in the first U-shaped groove 4011, the movable rail will interfere with the inner wall of the first U-shaped groove 4011. Therefore, the movable rail needs to be pushed out of the first U-shaped groove 4011 before it is flipped. In terms of the specific structure of the flipping mechanism 2, the flipping mechanism 2 is provided with two groups of outer walls of the two groups of fixed frames 401 opposite to each other, respectively connected to the outer walls of the two groups of fixed frames 401, the flipping mechanism 2 includes a rotating motor 201, a pushing cylinder 202, a lifting cylinder 203, and a second mounting seat 204.
