Technical Field

[0001] The utility model relates to the field of automobile seat processing and manufacturing, in particular to a punching and blanking device for automobile seat side panels. Background Art

[0002] The side panels of automobile seats are formed by stamping. In the prior art, during multiple stamping processes, manual loading and unloading are required, which has the following disadvantages: low efficiency of manual loading, unloading and positioning, which affects the production cost of enterprises; in addition, the cutter in the prior art is usually perpendicular to the sheet, which requires a wider sheet. Summary of the invention

[0003] The utility model aims at the deficiencies of the prior art and develops a punching and blanking device for the side panels of automobile seats. The technical solution adopted by the utility model is: a punching and blanking device for the side panels of automobile seats, characterized in that it includes a punching machine 1, a base 2 and a feeding device 3; an upper blade 4 is fixedly connected to the punching machine 1; a first upper cutter 5 and a second upper cutter 7 are respectively fixedly arranged at the lower part of the upper blade 4; a first lower cutter 6 and a second lower cutter 8 are respectively fixedly arranged on the base 2; the first upper cutter 5 cooperates with the first lower cutter 6 to cut materials; the second upper cutter 7 cooperates with the second lower cutter 8 to cut materials; a feeding guide block 9, a rotating positioning pin 10, a cylinder 11, a supporting positioning block 12 and a magnet 13 are respectively fixedly arranged on the base 2; and a material removal rod 14 is fixedly connected to the piston rod of the cylinder 11.

[0004] The benefits of the utility model are as follows: 1. Since a feeding device is used to replace workers' manual loading, unloading and positioning, the efficiency of the production line is greatly improved and the production cost is reduced; 2. Since the first upper and lower cutting knives and the second upper and lower cutting knives are respectively arranged at an angle to the material sheet, when punching seat side panels of the same size, a material sheet with a smaller width can be used, saving production costs.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] like Figure 1 and Figure 2 As shown, the utility model is a stamping and blanking device for a side panel of a car seat, comprising: a stamping machine 1, a base 2 and a feeding device 3; an upper knife plate 4 is fixedly connected to the stamping machine 1; a first upper cutter 5 and a second upper cutter 7 are respectively fixedly arranged at the lower part of the upper cutter plate 4; a first lower cutter 6 and a second lower cutter 8 are respectively fixedly arranged on the base 2; the first upper cutter 5 cooperates with the first lower cutter 6 to cut materials; the second upper cutter 7 cooperates with the second lower cutter 8 to cut materials; a feeding guide block 9, a rotating positioning pin 10, a cylinder 11, a supporting positioning block 12 and a magnet 13 are respectively fixedly arranged on the base 2; a material removing rod 14 is fixedly connected to the piston rod of the cylinder 11.

[0020] like Figure 1and Figure 3 As shown, during the specific operation, the worker operates the feeding device 3 to rotate, and the sheet of the coil is pushed from left to right between the first upper cutter 5 and the first lower cutter 6. The feeding guide block 9 ensures that the sheet moves smoothly, as shown in FIG. Figure 4 and Figure 5 As shown, at this time, the worker operates the punching machine 1 to work, the upper blade 4 is pressed down, the first upper cutter 5 and the first lower cutter 6 cooperate to complete the first punching of the sheet 15, and then the worker operates the punching machine 1 to raise the upper blade 4; at this time Figure 5 It can be seen that after cleaning the scraps on the first lower cutter 6, the right part of the seat side panel is punched out from the sheet 15, and the positioning hole 16 is also punched out, but the left part of the seat side panel is not punched out. Figure 6 and Figure 7 As shown, the feeding device 3 continues to rotate, and the sheet 15 continues to move to the right in the figure. Then the worker operates the punching machine 1 to perform a second punching. The first upper cutter 5 and the first lower cutter 6 cooperate to punch out the right part of the seat side panel from the sheet 15. At the same time, the second upper cutter 7 and the second lower cutter 8 cooperate to punch out the left part of the seat side panel. At this time, the seat side panel is separated from the sheet 15. Figures 8 to 11 As shown, the feeding device 3 described above continues to rotate, and the material sheet 15 continues to move to the right side of the figure. The material sheet 15 moves along the inclined surface of the material lever 14 and slides over the material lever 14. The material sheet 15 falls under the action of its own weight, and the material lever 14 clamps the left edge of the material sheet 15. Figure 7 As shown, at the same time, the sheet 15 also slides over the rotating positioning pin 10, and the sheet 15 falls under the action of its own weight, and the rotating positioning pin 10 is inserted into the positioning hole 16 on the sheet 15. Finally, the worker operates the piston rod of the cylinder 11 to retract, and the material pusher 14 moves to the right in the figure as the piston rod is retracted. The material pusher 14 pushes the stamped seat side panel on the sheet 15 to rotate counterclockwise with the rotating positioning pin 10 as the center of the circle. The lower end of the seat side panel is rotated to the support positioning block 12 and is attracted by the magnet 13 below it. Finally, the worker operates the manipulator to remove the stamped seat side panel.

[0021] According to the above process, continuous stamping production can be achieved.

[0022] In the prior art, since the cutter is usually perpendicular to the sheet, a coil with a width of 600 mm is usually used. In the utility model, since the cutter and the sheet are inclined, a coil with a width of 567 mm can be used to produce seat side panels of the same size, saving a certain amount of production cost.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
