Description

Technical Field

[0001] This utility model relates to the technical field of processing equipment, and in particular to a stamping mechanism and stamping equipment. Background Technology

[0002] Current stamping mechanisms require multiple stamping operations to prevent workpiece springback during bending. For example, when bending a workpiece at a 90-degree angle, a forming insert is first used in conjunction with a die with an inclined surface to bend the workpiece at a 45-degree angle. Then, another forming insert is used in conjunction with a die with a vertical or horizontal plane to achieve a 90-degree bend, ultimately forming a 90-degree bent product. Therefore, existing stamping mechanisms not only have low processing efficiency, but also, during multiple stamping operations, the workpiece surface is repeatedly contacted with the forming insert, resulting in severe stress and significant wear marks on the final product surface. This is especially true for softer materials, as the forming insert is typically made of materials such as SKH9 with a hardness of HRC58-62, leading to more severe wear marks and poor stamping quality. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a stamping mechanism and stamping equipment, which can improve stamping efficiency and stamping quality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0045] Unless otherwise stated or defined, the term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0046] For ease of description, unless otherwise stated, the terms "up" and "down" in the following text refer to the same direction as "top" and "bottom". Figure 3 Its left and right directions are consistent.

[0047] like Figures 1 to 10As shown, this embodiment provides a stamping mechanism for stamping workpiece 8, which is plate-shaped. The stamping mechanism can bend workpiece 8, and the bending angle can be 60 degrees, 90 degrees, 120 degrees, etc. In this embodiment, a 90-degree bend is used as an example. The raw material of workpiece 8 can be a rolled plate, which is cut into a plate shape by a cutting mechanism before stamping, and then stamped and bent into shape by the stamping mechanism.

[0048] The stamping mechanism includes a first mold 1, a second mold 2, and a forming insert 3. The first mold 1 and the second mold 2 can move relative to each other. In this embodiment, the first mold 1 moves downward and closes to the second mold 2 to switch to a closed state, completing the stamping process of the workpiece 8. After the stamping is completed, the first mold 1 moves upward away from the second mold 2 to switch to an open state, and the workpiece 8 can be placed on the second mold 2.

[0049] The first mold 1 has a first pressing surface 101 and a mounting groove 102 formed on the first pressing surface 101. The first pressing surface 101 is located on the lower end face of the first mold 1, and the lower end face faces downward toward the upper end face of the second mold 2.

[0050] The second mold 2 has a shaping surface 202 and a pressing surface 201. The second pressing surface 201 is located on the upper surface of the second mold 2, facing upwards toward the upper end face of the first mold 1, and is opposite to the first pressing surface 101. The shaping surface 202 is connected to and intersects with the second pressing surface 201, and forms a predetermined angle with the shaping surface 202 and the second pressing surface 201. The shaping surface 202 and the second pressing surface 201 are not parallel.

[0051] The forming insert 3 is at least partially rotatably mounted within the mounting groove 102. The forming insert 3 has a stamping surface 301, a positioning surface 302, and a driving portion 303 located outside the mounting groove 102, the driving portion 303 being a portion of the outer surface of the forming insert 3. The stamping surface 301 and the positioning surface 302 are connected and intersect, forming a predetermined angle between them. The stamping surface 301 and the positioning surface 302 are not parallel, and the stamping surface 301 and the positioning surface 302 can respectively conform to the shaping surface 202 and the second pressing surface 201. The forming insert 3 is used to bend a straight plate-shaped workpiece into the bent shape required by the drawing.

[0052] A receiving space 7 for accommodating the workpiece 8 is formed between the first pressing surface 101 and the second pressing surface 201. During processing, the workpiece 8 is located in the receiving space 7 and placed on the second pressing surface 201. The driving part 303 is located on the path of the second pressing surface 201 moving close to the first pressing surface 101. When the first mold 1 moves downward closer to the second mold 2, the second pressing surface 201 abuts against the driving part 303. That is, when the first pressing surface 101 and the second pressing surface 201 approach each other, the second pressing surface 201 abuts against the driving part 303 and pushes the driving part 303, causing the molding insert 3 to rotate. The driving part 303 rotates into the mounting groove 102, the positioning surface 302 rotates to be parallel to the second pressing surface 201, and the stamping surface 301 rotates outward from the mounting groove 102 and approaches the shaping surface 202. The rotation of the forming insert 3 allows the positioning surface 302 and the second pressing surface 201 to jointly clamp a portion of the workpiece 8. At this time, the positioning surface 302 is coplanar with the first pressing surface 101. When the workpiece 8 is long, a portion of the workpiece 8 is also clamped between the first pressing surface 101 and the second pressing surface 201. During this process, the stamping surface 301 bends another portion of the workpiece 8 and abuts against the shaping surface 202. The pressing force of the stamping surface 301 causes the other portion of the workpiece 8 to bend, thus completing the stamping of the workpiece 8.

[0053] Thus, before the workpiece 8 is stamped, the stamping mechanism of this application completely encloses the workpiece 8 within the receiving space 7. Specifically, the workpiece 8 is enclosed within the area formed by the stamping surface 301, the shaping surface 202, the second pressing surface 201, the first pressing surface 101, and the shaping surface 202. The workpiece 8 is then bent by rotating the forming insert 3. The forming insert 3 and the workpiece 8 are in line contact, reducing the friction between the workpiece 8 and the forming insert 3, reducing wear and scratches on the surface of the workpiece 8, and improving the processing quality. The workpiece 8 is bent in one step by rotating the forming insert 3, which improves efficiency. After the workpiece 8 is bent to the design value, the shaping surface 202, the stamping surface 301, and the bent part of the workpiece 8 are parallel to each other. The stamping surface 301 makes the bent part of the workpiece 8 completely fit against the shaping surface 202. At this time, the forming insert 3 cannot rotate and cannot cause wear and scratches on the workpiece 8.

[0054] Optionally, the first mold 1 is provided with a guide groove 103 extending along an arc trajectory, and the forming insert 3 is provided with a guide rod 4, which slides in the guide groove 103 to allow the forming insert 3 to rotate relative to the first mold 1. When the first mold 1 approaches the second mold 2, the second mold 2 pushes the forming insert 3 to slide along the guide groove 103, thereby allowing the forming insert 3 to rotate relative to the first mold 1 and the workpiece 8. During this process, the positioning surface 302 rotates to be parallel and in contact with the fixed part of the workpiece 8. The positioning surface 302 and the second pressing surface 201 clamp the fixed part of the workpiece 8. At the same time, the stamping surface 301 also squeezes the bent part of the workpiece 8, causing the bent part of the workpiece 8 to abut against the shaping surface 202. When the stamping surface 301 makes the bent part of the workpiece 8 completely in contact with the shaping surface 202, the bent part of the workpiece 8 is clamped between the stamping surface 301 and the shaping surface 202, thereby achieving the stamping forming of the workpiece 8. After workpiece 8 is stamped, the center of the guide groove 103 is located at the bend of workpiece 8.

[0055] Furthermore, multiple guide grooves 103 are provided on both sides of the mounting groove 102. The centers of the multiple guide grooves 103 on each side wall are the same. The first mold 1 is provided with multiple rod holes 305, and each rod hole 305 is through which a guide rod 4 passes. At least one elastic element 5 is connected to both ends of one of the guide rods 4, so that the rotation of the molded insert 3 is more stable. The multiple guide rods 4 correspond one-to-one with the guide grooves 103 on the side wall of the mounting groove 102. One end of each guide rod 4 slides in a guide groove 103 on one side wall of the mounting groove 102, and the other end of each guide rod 4 slides in a guide groove 103 on the other side wall of the mounting groove 102, further improving the rotational stability of the molded insert 3.

[0056] In one embodiment, the stamping mechanism further includes an elastic element 5. For example, the elastic element 5 is a columnar spring, i.e., a tension spring. One end of the elastic element 5 is connected to the first mold 1, and the other end is connected to the forming insert 3. When the second pressing surface 201 separates from the driving part 303, the elastic element 5 applies a spring force to rotate the driving part 303 outside the mounting groove 102. After the workpiece 8 completes stamping, the stamping mechanism switches to the mold-open state, the first mold 1 and the second mold 2 separate, and the forming insert 3 is restored to a distant position by the elastic element 5, so that the driving part 303 of the forming insert 3 is reset to outside the mounting groove 102, facilitating the second mold 2 to abut against the driving part 303 to rotate the forming insert 3 during the next stamping.

[0057] During the closing process of the first mold 1 and the second mold 2 approaching each other, after the first mold 1 drives the forming insert 3 to contact the surface of the workpiece 8 on the second mold 2, the first mold 1 continues to move downward. Under the push of the workpiece 8 and the second mold 2, the forming insert 3 moves along the guide groove 103 and rotates around the center of the guide groove 103 according to the positional structural characteristics of the second pressing surface 201 and the shaping surface 202 of the second mold 2. When the first mold 1 and the second mold 2 close, the workpiece 8 bends to the design value, which is the angle between the stamping surface 301 and the positioning surface 302. After the workpiece 8 completes the stamping, the first mold 1 and the second mold 2 separate to open the mold. During the mold opening process, the elastic element 5 pulls the forming insert 3 to rotate back to its original position.

[0058] In addition, to prevent the workpiece 8 from springing back, in other embodiments, the included angle between the stamping surface 301 and the positioning surface 302 can be increased according to the springback characteristics of the material of the workpiece 8, so that the included angle between the stamping surface 301 and the positioning surface 302 is slightly larger than the design value of the workpiece 8. For example, when it is necessary to stamp a workpiece 8 that is bent by 90 degrees, the included angle between the stamping surface 301 and the positioning surface 302 on the second mold 2 is designed to be 90 degrees to 92 degrees.

[0059] In other embodiments, the molding insert 3 can also be manually reset, or the driving part 303 of the molding workpiece 8 can be rotated out of the mounting groove 102 under the action of gravity by distributing the center of gravity of the molding insert 3.

[0060] Optionally, the first mold 1 is provided with a connecting rod 6, one end of the elastic element 5 is connected to the guide rod 4, and the other end of the elastic element 5 is connected to the connecting rod 6. The two ends of the elastic element 5 are respectively sleeved on the connecting rod 6 and the guide rod 4 for easy installation. The connection between the elastic element 5 and the molded insert 3 is realized through the connecting rod 6 and the guide rod 4.

[0061] Optionally, there are two elastic elements 5, which are arranged at intervals along the axis of the guide rod 4. The molded insert 3 is located between the two elastic elements 5, so that the rotation of the molded insert 3 is more stable.

[0062] Furthermore, the forming insert 3 also has an arc surface 304. The arc surface 304, the stamping surface 301, the positioning surface 302, and the driving part 303 are all the outer surfaces of the forming insert 3 and are all parallel to the axis of the guide rod 4. The arc surface 304, the stamping surface 301, the positioning surface 302, and the driving part 303 are connected end to end. The first mold 1 is provided with an arc groove 104. The forming insert 3 slides in the arc groove 104 and the arc surface 304 abuts against the inner wall of the arc groove 104. When the forming insert 3 rotates, it can conform to the inner rotation of the arc groove 104, making the rotation of the forming insert 3 more stable and precise, and improving the quality of stamping.

[0063] In one embodiment, the first mold 1 includes a first insert 105 and a support plate 106, a first mold base 107, a first pad 108, a clamping plate 109, a stop plate 110, and a release plate 111 connected in sequence. The support plate 106, the first mold base 107, the first pad 108, the clamping plate 109, the stop plate 110, and the release plate 111 are connected in sequence. The release plate 111 has a first insert groove 115, and the first insert 105 is installed in the first insert groove 115 of the release plate 111. The first pressing surface 101 and the mounting groove 102 are both located on the first insert 105.

[0064] The second mold 2 includes a second insert 203 and a pad 204, a second mold base 205, a second pad plate 206, and a template 207 connected in sequence. The pad 204, the second mold base 205, the second pad plate 206, and the template 207 are connected in sequence. A second insert groove 208 is provided on the template 207, and the second insert 203 is installed in the second insert groove 208 of the template 207. The second pressing surface 201 and the shaping surface 202 are both located on the second insert 203. When the product is bent, the product is formed according to the shape of the lower mold insert.

[0065] Furthermore, the first insert 105 includes a first insert 112, a second insert 113, and a third insert 114 connected in sequence. The first insert 112 and the third insert 114 have the same structure and are symmetrically distributed on both sides of the second insert 113. The first insert 112 and the second insert 113, and the third insert 114 and the second insert 113, are both formed with clearance grooves for installing the connecting rod 6. The first insert 112, the second insert 113, and the third insert 114 together form a receiving groove. The first pressing surface 101 is located on the second insert 113, and the arc-shaped sliding groove 104 is formed on the second insert 113.

Multiple mounting slots 102 are arranged at intervals, multiple forming inserts 3 are arranged at intervals, and multiple shaping surfaces 202 are arranged at intervals. This allows multiple workpieces 8 to be stamped simultaneously, improving stamping efficiency.

In this embodiment, a 90-degree bend can be achieved in the workpiece 8. Depending on the material properties of the workpiece 8, the included angles between the shaping surface 202 and the second pressing surface 201, and between the stamping surface 301 and the positioning surface 302, can be slightly greater than 90 degrees. In other embodiments, the included angles between the shaping surface 202 and the second pressing surface 201, and between the stamping surface 301 and the positioning surface 302, can also be 60 degrees, 80 degrees, or slightly greater than 60 degrees or 80 degrees, to achieve a 60-degree or 80-degree bend in the workpiece 8.

[0068] Optionally, the shaping surface 202 is smoothly connected to the second pressing surface 201, and the stamping surface 301 is smoothly connected to the positioning surface 302. An outer rounded corner is provided between the shaping surface 202 and the second pressing surface 201, and between the stamping surface 301 and the positioning surface 302.
