Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining equipment, and more specifically to a pneumatic press foot for a metal sheet grooving machine. Background Technology
[0002] Metal sheets are widely used in modern industrial production, undergoing various processing methods such as bending, extrusion, and stamping to create desired shapes. For example, stamping metal sheets using molds creates the external structural form of automobiles. The production of doors, windows, or technical furniture requires bending metal sheets. To achieve a smaller radius of curvature and a more refined appearance after bending, the metal sheet needs to be grooved before bending. Machine tools for grooving thin metal sheets are typically classified as vertical or gantry-type.
[0003] For gantry-type grooving machines, the existing technology disclosed in Chinese Utility Model Patent 201520041942.1, which describes an automatic rotary tool holder device for gantry-type thin plate grooving machines, achieves grooving in both longitudinal and transverse directions through the rotation of the tool holder. Therefore, for gantry-type plate grooving machines, it is necessary to clamp and fix the metal sheet on the sides to prevent the sheet from moving during grooving. The pressure foot in the existing technology has the following drawbacks:
[0004] 1. The length of the sheet metal gripped by the presser foot clamp is always the same. However, in actual processing, the length of the sheet metal that the clamp holds should be related to the depth of the groove that needs to be cut into the sheet metal. If the groove is deep but the clamping length is small, the sheet metal will also move.
[0005] 2. Existing side clamps can only neatly fix the edges of the board. That is to say, when the edge of the board has a curved or irregular shape, the existing clamps cannot completely press the edge of the board and cannot fix the board, thus limiting their applicability. Utility Model Content
[0006] To address the aforementioned problems, the purpose of this utility model is to provide a pneumatic presser foot for metal sheet grooving machines that features a simple structure, diverse angle adjustments, stable clamping, wide applicability, and adjustable clamping length.
[0007] According to one aspect of this utility model, a pneumatic presser foot for a metal sheet grooving machine is provided, comprising: a moving part, a rotating part, a first mounting plate, a clamping part, and an adjusting part. The clamping part is disposed at the top of the front end of the first mounting plate, and the rotating part is disposed at the bottom of the rear end of the first mounting plate. The rotating part drives the first mounting plate to rotate and is mounted on a second mounting plate. The output end of the moving part is fixedly connected to the second mounting plate, which is fixedly disposed between the rotating part and the first mounting plate. The moving part drives the second mounting plate to reciprocate. The moving part drives the clamping part and the adjusting part to move closer to or further away from the sheet metal, the rotating part drives the clamping part and the adjusting part to rotate to adapt to clamping sheets of different specifications, and the adjusting part facilitates adjustment of the length of the clamped sheet metal.
[0008] In some embodiments, the clamping part includes: a first mounting base, a second mounting base, a rotating shaft, a clamp, and a first driving member. The first and second mounting bases are symmetrically mounted on the top of a first mounting plate. The rotating shaft is mounted on the first and second mounting bases. The front end of the clamp passes through the rotating shaft, and the rear end of the clamp is connected to the output end of the first driving member. The first driving member is mounted on the bottom of the first mounting base, and its output end passes through the first mounting base and connects to the rear end of the clamp. The first driving member drives the front end of the clamp to lift or press down, thereby clamping the plate for fixation.
[0009] In some embodiments, the adjustment unit includes: a first limiting block, a second limiting block, a fixing bolt, and an adjusting bolt. The first limiting block has at least two oblong holes, and the second limiting block has at least two oblong holes. The fixing bolt passes through the oblong holes to fix the first and second limiting blocks to a first mounting plate. The adjusting bolt engages with the first limiting block and its bottom abuts against a first mounting seat, and the adjusting bolt engages with the second limiting block and its bottom abuts against a second mounting seat. By adjusting the adjusting bolt against the first mounting seat, the positions of the first and second limiting blocks are adjusted, ultimately achieving adjustment of the clamping length of the clamping head on the plate, adapting to the fixing of plates of different shapes.
[0010] In some embodiments, the front end of the first limiting block has a gap A with the edge of the first mounting plate, and the front end of the second limiting block has a gap B with the edge of the first mounting plate. The lengths of gap A and gap B may be the same or different. By adjusting the lengths of gap A and gap B, the clamp can adapt to the fixing of edges of plates with different shapes.
[0011] In some embodiments, the first limiting block is L-shaped and includes a first fixing block and a second fixing block. The second fixing block is vertically fixed to one end of the first fixing block, and the other end of the first fixing block is close to the edge of the first mounting plate. The first fixing block has at least two oblong holes, and the second fixing block has threaded holes. By setting the first and second limiting blocks to L-shape, the fixing bolts' fixation of the first and second limiting blocks is not affected, nor is the adjusting bolts' adjustment of the gap length between the front ends of the first and second limiting blocks and the edge of the first mounting plate.
[0012] In some implementations, the structure of the first limiting block is the same as that of the second limiting block.
[0013] In some embodiments, the first driving element is a cylinder. The clamping and releasing of the clamps are achieved by driving the cylinder.
[0014] In some embodiments, the rotating part is a rotary cylinder. The rotary cylinder facilitates the rotation of the clamping and adjusting parts to accommodate edge fixing of plates with different shapes.
[0015] In some embodiments, the moving part is a cylinder. The cylinder facilitates pushing the clamping part and the adjusting part closer to or away from the sheet metal.
[0016] This utility model discloses a pneumatic presser foot for a metal sheet grooving machine. A moving part drives the clamping and adjusting parts to move closer to or further away from the sheet metal. A rotating part drives the clamping and adjusting parts to rotate, adapting to clamping sheets of different specifications. The adjusting part facilitates adjustment of the length of the clamped sheet metal. A first driving member drives the front end of the clamp to lift or press down, thereby clamping and fixing the sheet metal. An adjusting bolt abuts against the first mounting base, thereby adjusting the position of the first and second limiting blocks, ultimately achieving adjustment of the clamping length of the sheet metal by the front end of the clamp, adapting to the fixing of sheets of different shapes. The clamp can be adapted to fix the edges of different shaped plates by adjusting the lengths of gaps A and B; by setting the first and second limiting blocks to L-shapes, it does not affect the fixing of the first and second limiting blocks by the fixing bolts, nor does it affect the adjustment of the gap length between the front end of the first and second limiting blocks and the edge of the first mounting plate by the adjusting bolts; the clamping and releasing of the clamp is achieved by cylinder drive; the rotation of the clamping part and the adjusting part can be easily realized by the rotary cylinder to adapt to the edge fixing of different shaped plates; the clamping part and the adjusting part can be easily pushed closer to or away from the plate by the cylinder.

The rotary cylinder is a 180° rotary cylinder; its initial position is 90°, allowing for rotation in both directions of 90°.
[0024] The moving part 1 is a cylinder. The cylinder facilitates the movement of the clamping part 4 and the adjusting part 5 towards or away from the sheet metal.
[0025] like Figure 2As shown, the clamping part 4 includes: a first mounting base 41, a second mounting base 42, a rotating shaft 43, a clamp 44, and a first driving member 45.

The first driving member 45 is mounted on the bottom of the first mounting base 41, and its output end passes through the first mounting base 41 and connects to the rear end of the clamp 44. The first driving member 45 drives the front end of the clamp 44 to lift or press down, thereby clamping the plate and fixing it.
[0026] like Figure 3 As shown, the adjustment part 5 includes: a first limiting block 51, a second limiting block 52, a fixing bolt 53, and an adjusting bolt 54. The first limiting block 51 has at least two oblong holes 55, and the second limiting block 52 has at least two oblong holes 55.
