Description

Technical Field

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0033] Combine Figure 1 and Figure 14 As shown, the utility model discloses a new type of mold for forming picture frame corner nails, including a feed table 100 and a forming mold assembly 200. The forming mold assembly 200 includes a first module 260 and a second module 270. The first module 260 is used to shear and separate the material, and the second module 270 is used to extrude and form the sheared material. By integrating the first module 260 and the second module 270 inside the forming mold assembly 200, synchronous processing and forming of different processes can be achieved, thereby improving overall production efficiency.

[0034] In the specific structure, a material spacing table 280 is set between the first die set 260 and the second die set 270. The first die set 260 includes an upper cutting die 261 and a lower cutting die 262. A plurality of material cavities 263 are formed between the upper cutting die 261 and the lower cutting die 262. A first cutting knife group 264 is set between any two adjacent material cavities 263. A second cutting knife group 265 is set on the discharge end surface of the upper cutting die 261 and the lower cutting die 262. The knife group 264 is used to realize longitudinal cutting of the material. The material is usually a thin iron plate. After entering along the feeding direction, the first cutting knife group 264 is used to separate the material into multiple strips. In one preferred embodiment, the material cavity 263 adopts 7 strips, and 6 first cutting knife groups 263 are used for cutting and separating. As the material enters, the material after longitudinal separation enters the material spacing table 280, and the second cutting knife group 265 is used to realize transverse cutting and separation. The cutting and separation makes the material into a semi-finished product. The second cutting knife group 265 realizes cutting of the length size of the material to form the semi-finished material required by the corresponding specifications, and sequentially arranges it into the material spacing table 280; in the specific structure, the first cutting knife group 264 includes a first upper blade 2641 and a first lower blade 2642, and the second cutting knife group 265 includes a second upper blade 2651 and a second lower blade 2652. The first upper blade 2641 and the second upper blade 2651 are both located on the upper cutting die 261. The lower blade 2642 and the second lower blade 2652 are both located on the lower cutting die 262, the first upper blade 2641 and the second upper blade 2651 are arranged horizontally and vertically, and the first lower blade 2642 and the second lower blade 2652 are arranged horizontally and vertically. The first upper blade 2641 and the first lower blade 2642 are used to achieve longitudinal cutting and separation of the material, and the second upper blade 2651 and the second lower blade 2652 are used to achieve transverse cutting and semi-separation of the material to form semi-product materials of corresponding specifications.

[0035] Preferably, the material spacing table 280 has a size of 57mm-60mm along the material processing direction, wherein the material spacing table 280 preferably has a size of 58mm along the material processing direction. Combined with the corresponding specifications of the photo frame corner nails in the prior art, it is preferred to adopt a 58mm length size specification, which can be applicable to the processing and production of the corresponding specifications in the prior art. For example, if it is required to process 5# photo frame corner nails, the second cutter group 265 in the first module 260 is set to a length specification size of 58mm / 12 or 58mm / 13 for cutting when cutting the length. The length size is usually 4.8mm / 4.46mm, the size tolerance is usually -0.8mm~0.5mm, and for the sake of product manufacturing cost, negative tolerance is usually preferred to reduce manufacturing cost. The size specification of the photo frame corner nail has looser tolerance requirements. The 4.8mm / 4.46mm length dimension belongs to the 5# specification, that is, in the corresponding different specifications, the material spacing table 280 single material cavity 263 corresponds to the one-time arrangement of 12 or 13 5# specification photo frame corner nails, preferably 13; if the 7# specification photo frame corner nail is used, the second cutter group 265 in the first module performs length When cutting, the length specification size of 58mm / 9 is set for cutting. Usually the length size is 6.44mm. The dimensional tolerance is allowed. Because the size specifications of the picture frame corner nails are relatively loose in terms of tolerance requirements, within a reasonable tolerance range, the 6.44mm scale size belongs to the 7# specification. The material spacing table 280 single material cavity 263 corresponds to the one-time arrangement of 9 7# picture frame corner nails; if the 9# picture frame corner nails are processed, the material spacing table 280 single material cavity 263 corresponds to the one-time arrangement of 7 9# picture frame corner nails; if the 10# specification is processed For picture frame corner nails, the single material cavity 263 of the material spacing table 280 corresponds to the one-time arrangement of 6 10# picture frame corner nails; if 12# picture frame corner nails are used, the single material cavity 263 of the material spacing table 280 corresponds to the one-time arrangement of 5 12# picture frame corner nails; if 15# picture frame corner nails are used, the single material cavity 263 of the material spacing table 280 corresponds to the one-time arrangement of 4 15# picture frame corner nails; for this reason, in this embodiment, the material spacing table 280 is set to 58mm, which can be applied to the production of picture frame corner nails of various specifications to the greatest extent.

[0036] According to the corresponding different specifications and sizes, if it is necessary to manufacture picture frame corner nails with higher precision requirements, the size specifications of the material spacer can also be adjusted accordingly to meet the corresponding specification precision requirements.

[0037] In combination with the above, the feed table 100 adopts a feeding transmission coordinated with a servo motor, and the corresponding specification of photo frame corner nails can be obtained by inputting the corresponding parameter values ​​​​through the control panel, among which the inputs such as the feeding transmission rate and the control panel control parameters belong to the electronic control system, which can be realized in combination with the commonly used electronic control system in the prior art.

[0038] In combination with the above, the second module 270 includes an upper molding die 271 and a lower molding die 272, and a plurality of molding cavities 274 are formed between the upper molding die 271 and the lower molding die 272.

[0039] Preferably, the number of molding cavities 274 and material cavities 263 is the same, both of which are 2 to 15. According to the different numbers of molding cavities 274 and material cavities 263, in order to change the relevant template size, it is usually necessary to match the corresponding stamping equipment so that it is suitable for product stamping and forming. Production equipment of corresponding specifications can be formed. Combined with the corresponding stamping equipment models in the prior art, according to the production scale and the required manufacturing cost, the preferred number of molding cavities 274 and material cavities 263 is 6, 7, and 8.

During the processing, the material to be processed is fed into the feed cavity through the feed table 100. As the material continues to enter, the first die group 260 is first used to press the material into the feed cavity. After the material is cut, the material is continuously fed until the material spacing table 280 is filled and then enters the second die set 270 for product forming. After the products in the second die set 270 are sorted, the materials are dropped in sequence. During the processing, the lower die assembly is usually a fixed die, and the lower die assembly includes a lower die base 250 at the bottom, and the feed die table 240, the lower cutting die 262, the material spacing table 280 and the lower forming die 272 are arranged on the lower die base 250 from the feed table 100 to the discharge seat 290 in sequence.
