Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat guide rail processing, in particular to a rolling forming device for automobile seat guide rails. Background Art

[0002] The car seat rail is a mechanical device installed on the car body. Its main function is to allow the seat to slide forward and backward in the car to adjust the passenger's sitting position and provide a comfortable riding experience. This device usually consists of two parts: a fixed rail on the seat base and a movable rail on the bottom of the car body. The roll forming equipment of the car seat rail is a tool and equipment used to produce rails. Its function is to process metal sheets into rails of the required shape and size through the roll forming process. Roll forming is a common metal forming process that gradually forms the required curves and contours by applying pressure and bending force to the metal sheet. Specifically, the roll forming equipment usually consists of a series of rollers, which can gradually bend the metal sheet into the required shape through different layouts and rotation methods. Equipment operators can adjust the position and pressure of the rollers according to design requirements to ensure that guide rail products that meet specifications are produced. However, the current roll-forming equipment mainly uses multiple parallel support rollers to horizontally convey and support the steel strip materials when loading and rolling the guide rail steel strip materials. However, the steel strip materials are relatively long, and they are prone to deviation and dislocation during long-distance transportation. This causes the steel strip materials to deviate from the rolling point, and inaccurate rolling position will directly lead to dimensional deviations in the produced guide rails, thereby affecting the installation and use of the seat rails.

[0020] The pulley rolling unit 10 is composed of a pulley driving structure 1001 and a lower rolling roller 1002. A plurality of lower rolling rollers 1002 are rotatably installed at equal intervals inside the support frame 1 below the lifting rolling unit 6. The pulley driving structure 1001 is arranged on the back of the support seat 4 to drive the plurality of lower rolling rollers 1002 to rotate together. When feeding the steel strip material, the rotary power of the pulley driving structure 1001 is transmitted to the plurality of lower rolling rollers 1002. At this time, the plurality of lower rolling rollers 1002 roll and convey the steel strip material together under the downward pressure of the lifting rolling unit 6.

[0021] The lifting and rolling unit 6 includes a C-shaped frame 5 fixed on one side of the top of the support seat 4, and a main hydraulic cylinder 601 installed on the top of the C-shaped frame 5. The bottom end of the piston rod of the main hydraulic cylinder 601 is installed with a lower support frame 602. The lower support frame 602 is internally rotatably installed with a plurality of equidistant upper rolling rollers 603. The lifting and rolling unit 6 is responsible for adjusting the rolling force and position to ensure that the rolling process of the steel strip is stable and reliable. The lower support frame 602 and the upper rolling roller 603 are pushed downward by the main hydraulic cylinder 601. At this time, the upper rolling roller 603 and the lower rolling roller 1002 jointly apply force and roll the steel strip material, so as to process the steel strip material into a guide rail product of a desired shape and size.

[0022] The steel belt dual-axis lifting mechanism 3 includes a U-shaped support 301 fixed to one side of the inner part of the support frame 1, and a slide 303 slidably installed at the bottom of the U-shaped support 301, a Y-axis cylinder 302 for driving the slide 303 to slide along the Y axis is installed on one side of the bottom end of the U-shaped support 301, a Z-axis cylinder 304 is installed on the top of the slide 303, and a support plate 305 is fixed on the top of the piston rod of the Z-axis cylinder 304;

[0023] The staff starts the Y-axis cylinder 302 and the slide 303 to work. Since the steel strip material is located on the support plate 305, when the Y-axis cylinder 302 is working, the Y-axis cylinder 302 pulls the slide 303, the Z-axis cylinder 304, the support plate 305 and the steel strip material to move in the Y-axis direction, and the Z-axis cylinder 304 drives the support plate 305 and the steel strip material to move up and down, thereby accurately adjusting the steel strip material in the Y-axis and Z-axis directions. In this process, the workload of the operator can be reduced, and it is convenient for the staff to adjust the position of the material on the production line;

[0024] A U-shaped steel belt limiting mechanism 11 is installed on the inner wall of one side of the support frame 1. The U-shaped steel belt limiting mechanism 11 includes an electric push rod installed on the inner wall of one side of the support frame 1, and a right angle frame installed on the top of the piston rod of the electric push rod. A plurality of vertical steel rollers are rotatably installed on the top of the right angle frame. When the cross section of the steel belt is formed into a U shape, the steel belt can be further tightened and limited by the U-shaped steel belt limiting mechanism 11.

[0025] The guide rail cutting unit 8 includes a column 801 installed on the top of the platform 7, and a top plate 802 installed on the top of the column 801, a secondary hydraulic cylinder 803 is fixed to one side of the top of the top plate 802, a secondary slide 804 is fixed to the bottom end of the piston rod of the secondary hydraulic cylinder 803, and a cutting knife 805 is installed on one side of the bottom end of the secondary slide 804, and a boss 806 is fixed to one side of the top of the platform 7. After the guide rail is roller-formed, the staff starts the secondary hydraulic cylinder 803 through the PLC control panel 9, and the secondary hydraulic cylinder 803 pushes the secondary slide 804 and the cutting knife 805 downward until the cutting knife 805 cuts the guide rail. The guide rail cutting unit 8 can adjust the cutting size and length according to actual needs to ensure that the material of each section of the guide rail is fully utilized and reduce the generation of residual material.

[0026] When the embodiment of the present application is in use, the staff first introduces the car seat steel strip material to be roll-formed onto the support roller 2, and finally passes the end of the steel strip material through the pulley rolling unit 10 and the lifting rolling unit 6 until the end of the steel strip material is led out from the guide rail cutting unit 8. During this process, the staff turns on the pulley rolling unit 10 through the PLC control panel 9, and the lifting rolling unit 6 applies a downward force to the steel strip material. During the conveying and extrusion of the steel strip material, the metal sheet is gradually bent into the desired shape, that is, a deeper groove is pressed in the middle of the steel strip. The equipment operator can adjust the downward pressure of the lifting rolling unit 6 according to the design requirements to ensure the production of guide rail products that meet the specifications, and the formed after rolling. The car seat rails are cut by the rail cutting unit 8 to cut out car seat rail products of a required length. During the process of the pulley rolling unit 10 and the supporting roller 2 conveying the steel strip material, the staff can start the steel strip dual-axis lifting mechanism 3 through the PLC control panel 9 to work. The steel strip dual-axis lifting mechanism 3 adjusts the Y-axis and Z-axis positions of the steel strip material in the corresponding area segment, so as to achieve precise adjustment of the steel strip material in the Y-axis and Z-axis directions. Therefore, during the conveying process, the position of the steel strip material can be more accurately controlled to prevent deviation and misalignment. By accurately adjusting the position of the steel strip material, it can be ensured that it accurately enters the rolling point, thereby improving the accuracy and stability of the rolling process and improving the consistency and quality of the product.
