Description

TECHNICAL FIELD

[0001] The utility model relates to punch press equipment technical field, specifically relate to sheet material feeding device. BACKGROUND

[0002] Punch press is the commonly used equipment in mechanical processing, and is mainly used for directly obtaining products according to die forming by stamping sheet metal. Chinese patent authorization announcement No. CN201192711Y discloses a numerical control full-automatic punch press, and the working principle of the steel sheet pickup device thereof is that the steel sheet is placed on the automatic lifting table, the piston rods of two groups of plate pickup cylinders are lowered, the suction cups thereon suck the steel sheet, the piston rods of the plate pickup cylinders are raised to lift the steel sheet upward, after being lifted to the position, the horizontal cylinder pushes the left end plate pickup cylinder to drive the steel sheet to deflect left and be sent into the plate feeding and oiling variable speed device. In the process that the steel sheet is deflected left by the horizontal cylinder pushing the left end plate pickup cylinder, the right end plate pickup cylinder needs to release the steel sheet sheet, and due to gravity, the right end of the steel sheet sheet will fall to the lifting workbench and contact the surface of the steel sheet sheet. Since burrs may exist around the steel sheet sheet, the right end of the steel sheet sheet will scratch the surface of the steel sheet sheet on the lifting workbench in the moving process, and the quality of the product after stamping is affected.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] In the embodiments, such as Figure 1 , Figure 2 As shown, the sheet feeding device includes a frame 1, and also includes:

[0025] A horizontal reciprocating mechanism 2 is mounted on the frame 1 and extends partially outside the frame 1;

[0026] Mounting base 3 is installed on horizontal reciprocating mechanism 2;

[0027] Telescopic elements 4, at least one set, are symmetrically arranged on both sides of the mounting base 3;

[0028] Vacuum suction cup 5 is installed on the telescopic end of telescopic element 4.

[0029] The telescopic element 4 is a pneumatic or electric cylinder, and the horizontal reciprocating mechanism 2 is a synchronous belt mechanism. The telescopic element 4 descends, the vacuum suction cup 5 picks up the sheet material, and then the telescopic element 4 resets. The horizontal reciprocating mechanism 2 drives the sheet material to move horizontally forward and move it outside the frame 1, and then releases the sheet material to enter the next process. During the movement of the sheet material, its periphery will not come into contact with the sheet material surface on the lifting worktable, thereby ensuring the quality of the product after each sheet material is stamped.

[0030] In the embodiments, such as Figure 1 , Figure 2 As shown, the distance between the telescopic elements 4 is adjustable. This allows it to adapt to sheets of different widths, offering good versatility.

[0031] In the embodiments, such as Figure 1 , Figure 2 As shown, a profile 6 is mounted on the mounting base 3, and a connecting plate 7 is provided between the profile 6 and the telescopic element 4. The connecting plate 7 has a slotted hole 8, through which bolts pass to engage with the profile 6. The distance between the telescopic elements 4 can be adjusted by loosening the bolts and moving the connecting plate 7, making adjustment convenient.

[0032] In the embodiments, such as Figure 1 As shown, the horizontal reciprocating mechanism 2 has guide rail assemblies 9 on both sides for cooperating with the mounting base 3. This ensures the straightness of the plate conveying, thereby ensuring conveying accuracy.

[0033] In the embodiments, such as Figure 1 , Figure 2 As shown, the telescopic element 4 consists of two sets, respectively located at the front and rear ends of the mounting base 3. The telescopic element 4 is equipped with a suction cup holder, which can hold multiple vacuum suction cups 5, allowing the sheet material to be lifted horizontally and preventing the periphery of the sheet material from tilting downwards and contacting the surface of the sheet material below.

[0034] In the embodiments, such as Figure 1 , Figure 3 , Figure 4 As shown, it also includes a side baffle 10 disposed on the outside of the telescopic element 4. The side baffle 10 has a mounting groove 11 on its outer side, and a magnet 12 is installed in the mounting groove 11. The magnet 12 is used to separate the sheet material and prevent overlapping sheets from being attracted up. Placing the magnet 12 in the mounting groove 10 makes it less likely for the magnet 12 to fall off the side baffle 10, and also protects the magnet 12 from damage caused by collisions with external objects.

[0035] In the embodiments, such as Figure 1 ,Figure 3 As shown, the rack 1 is provided with a lead screw mechanism 13, the lead screw mechanism 13 is provided with a mounting plate 14, the side baffle 10 is mounted on the mounting plate 14, the lead screw mechanism 13 is provided with a guide rod 15 on both sides, the guide rod 15 is mounted with a guide sleeve 16 for cooperation with the mounting plate 14. Two side baffles 10 are respectively provided with a lead screw mechanism 13, by rotating the lead screw mechanism 13, the distance between the side baffles 10 can be adjusted, and then different sizes of sheet materials can be adapted, and the versatility is good.

[0036] Obviously, the above embodiments of the present application are only examples for illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived from the essential spirit of the present application still belong to the protection scope of the present application.
