Description

Technical Field

[0001] This utility model relates to the technical field of molds, and in particular to an indirect buffer clamp for mold machine tools. Background Technology

[0002] In the metal sheet stamping process, the metal sheet needs to be placed between an upper and lower die, and formed into a specific shape by the extrusion of the upper and lower dies. During the stamping process, a bending section will occur. This bending section will cause both sides of the metal sheet to compensate towards the bending point (i.e., both sides will move towards the bending point). As a result, the distance between the edge of the metal sheet and the bending point cannot be controlled during the stamping process. After stamping, the two sides of the metal sheet need to be trimmed to obtain the corresponding dimensions, which increases the stamping process and affects production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an indirect buffer fixture for mold machine tools to solve the problem of uncontrollable spacing between the two sides during the stamping process of metal plates.

[0004] Based on the technical problems existing in the background art, this utility model proposes an indirect buffer fixture for mold machine tools, including multiple machine bases fixed on the worktable and platforms fixed on the top of the machine bases. Each platform has a fixture assembly that is longitudinally slidably installed below the middle, and each platform has a drive component that penetrates the platform and is connected to the fixture assembly.

[0005] Preferably, an extension block is provided on the side of the platform, the clamping assembly is located directly below the extension block, and the drive unit is located directly above the extension block and passes through the extension block to connect with the clamping assembly.

[0006] Preferably, the driving component is a cylinder.

[0007] Preferably, the clamping assembly includes a sliding plate, and at least two first sliding posts are provided above the sliding plate. The first sliding posts extend from the bottom of the extension block to the top of the extension block. The first sliding posts can slide longitudinally relative to the extension block, and a nut is connected to the top of the first sliding post.

[0008] Preferably, the clamp assembly further includes a clamping plate, and at least two second sliding pillars are provided above the clamping plate. The second sliding pillars extend from the bottom of the slide plate to the top of the slide plate. The second sliding pillars can slide longitudinally relative to the clamping plate. A nut is connected to the top of the second sliding pillar. An elastic element is sleeved on the second sliding pillar. The two ends of the elastic element abut against the clamping plate and the slide plate, respectively.

[0009] Preferably, a rubber sheet is attached to the underside of the clamping plate.

[0010] Compared with the prior art, the indirect buffer fixture for mold machine tools proposed in this utility model adopts the above technical solution and achieves the following technical effects:

[0011] This invention can buffer the downward pressure on the metal plate, relieve the pressure on the metal plate, prevent deformation, and effectively fix the metal plate on the worktable. This invention can also prevent the device from being damaged by excessive pressure through the buffering effect, thus improving safety. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] Example

[0017] Please refer to Figures 1-2 This utility model proposes an indirect buffer clamp for a mold machine tool, including multiple bases 2 fixed on a worktable 1 and a platform 3 fixed on the top of the base 2. A clamping assembly 4 is longitudinally slidably installed below the middle of each platform 3. A driving component 5 is installed on each platform 3, penetrating the platform 3 and connected to the clamping assembly 4. In this solution, multiple bases 2 are installed on the worktable 1 in a straight line. When clamping is required, the metal plate is pressed against the base 2. The driving component 5 drives the clamping assembly 4 and the worktable 1 to clamp the metal plate, keeping the stamping side of the metal plate from shifting. The driving component 5 needs to maintain the clamping state for a certain period of time after clamping the metal plate to meet the entire stamping process of the metal plate.

[0018] In specific implementation, refer to Figure 1 , Figure 2An extension block 31 is provided on the side of the platform 3, the clamping assembly 4 is located directly below the extension block 31, and the driving component 5 is located directly above the extension block 31 and passes through the extension block 31 to connect with the clamping assembly 4. In this solution, the platform 3 uses the extension block 31 to move the clamping assembly 4 so that the clamping assembly 4 will not squeeze the machine base 2 when it is pressed down, and can cooperate with the worktable 1 to clamp the metal plate.

[0019] In specific implementation, refer to Figure 1 , Figure 2 The driving component 5 is a cylinder; in this solution, the clamping assembly 4 can also be driven by a gear and rack; the use of a cylinder in this solution can reduce costs, and the control is reduced by driving only by pneumatic means.

[0020] In specific implementation, refer to Figure 1 , Figure 2 The clamping assembly 4 includes a slide plate 41, and at least two first sliding posts 42 are provided on the top of the slide plate 41. The first sliding posts 42 extend from the bottom of the extension block 31 to the top of the extension block 31. The first sliding posts 42 can slide longitudinally relative to the extension block 31. A nut is connected to the top of the first sliding post 42. In this solution, the nut is located above the extension block 31, which can restrict the first sliding post 42 from sliding downward and disengaging from the extension block 31. When the cylinder drives the slide plate 41 longitudinally, its first sliding posts 42 can provide a stabilizing bar effect for the slide plate 41, preventing the slide plate 41 from rotating relative to the flagpole.

[0021] In specific implementation, refer to Figure 1 , Figure 2 The clamping assembly 4 also includes a clamping plate 43. At least two second sliding pillars 44 are provided above the clamping plate 43. The second sliding pillars 44 extend from below the slide plate 41 to above the slide plate 41. The second sliding pillars 44 can slide longitudinally relative to the clamping plate 43. A nut is connected to the top of the second sliding pillar 44. An elastic element 45 is sleeved on the second sliding pillar 44. The two ends of the elastic element 45 abut against the clamping plate 43 and the slide plate 41, respectively. In this solution, by setting the longitudinally sliding clamping plate 43, the downward pressure on the slide plate 41 is transferred to the clamping plate 43 through the elastic element 45. The clamping force of the clamping plate 43 on the metal plate is not constant. It can be buffered by the elastic element 45, which can avoid excessive clamping and damage to the metal plate, and can also prevent the entire clamping assembly 4 from being excessively damaged by clamping, thus improving stability.

[0022] In specific implementation, refer to Figure 1 , Figure 2 A rubber plate 6 is attached to the bottom of the clamping plate 43. In this solution, the rubber plate 6 can prevent the clamping plate 43 from excessively squeezing the metal plate and causing deformation of the metal plate. At the same time, it can increase the friction between the clamping plate 43 and the metal plate and prevent the metal plate from sliding horizontally relative to the clamping plate 43.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
