[0002] Wrenches belong to the category of mechanical hardware hand tools. There are many types of wrenches and their uses, such as simple hex wrenches, ultra-thin simple single-ended wrenches, and ultra-thin simple open-end wrenches. These can all be formed by stamping or bending using a wrench forming machine.

[0003] However, existing wrench forming machines can only process a single product type. For example, a wrench forming machine for processing hexagonal wrenches can only bend and cut hexagonal steel wire, while it cannot be formed by bending and cutting to produce ultra-thin simple open-end wrenches. This results in different wrench forming machines being needed to produce different types of wrench products, leading to high investment costs for enterprises in production equipment.

[0030] The present invention will be described in detail below with reference to specific embodiments.

[0031] In this utility model, when directional terms appear, they are used to facilitate the description of this utility model and simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this utility model.

[0032] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] As shown in Figures 1 to 3, a metal product forming machine includes a frame 10, a feeding and straightening device 20, a pressure roller feeding device 30, a stamping die 40, and a cutting and bending device 50.

[0034] The feeding straightening device 20 is mounted on the frame 10 and is used to straighten the fed metal wire. The pressure roller feeding device 30 is mounted on the discharge end of the feeding straightening device 20 and is used to drive the metal wire to move and feed. The stamping die 40 is mounted on the discharge end of the pressure roller feeding device 30. The die plate 41 of the stamping die 40 is provided with a material passage hole 42 for the metal wire to pass through. The stamping die 40 is used to punch the metal wire. The cutting and bending device 50 is mounted on one side of the discharge end of the die and can be slidably adjusted along the longitudinal direction of the frame 10. It is used to cut and bend the metal wire.

[0035] The metal lines mentioned in this embodiment can be circular metal lines, flat metal lines, polygonal metal lines, or rectangular metal lines.

[0036] In practice, the stamping die 40 is driven by a hydraulic cylinder, and the frame 10 is equipped with a hydraulic station 11 connected to the hydraulic cylinder. The feed straightening device 20, the pressure roller feeding device 30, and the feed port and discharge port of the material passage 42 are all on the same straight line. The feed port of the cutting and bending device 50 can be adjusted to keep it on the same straight line as the discharge port of the material passage 42.

[0037] The metal wire enters from the feed end of the feeding and straightening device 20. Driven by the pressure roller feeding device 30, the metal wire is moved and fed. When the type of product requires a stamping and punching process, the upper and lower templates of the desired product are changed on the stamping die 40. The metal wire (e.g., a flat metal wire) enters the stamping die 40 through the material passage hole on the ejector plate 41. The stamping die 40 stamps the metal wire to form the desired shape (e.g., an ultra-thin simple open-end wrench). For example, through continuous feeding by the pressure roller feeding device 30, the formed product is pushed out of the stamping die 40. When the type of product requires a cutting and bending process, the cutting and bending device 50 is adjusted to align with the feeding direction.

[0038] The metal wire (e.g., a polygonal metal wire) is fed through the material passage of the stamping die 40 into the cutting and bending device 50 for cutting and bending to form a product of the desired shape (e.g., a right-angle hexagonal wrench).

[0039] In this embodiment, a guide seat 43 is provided between the discharge end of the feed hole 42 and the feed end of the cutting device, which facilitates the connection of the metal wire to the feed port of the cutting and bending device 50.

[0040] As shown in Figure 4, in this embodiment, the feeding straightening device 20 includes a line straightening bracket 21. A connecting vertical plate 22 and a connecting flat plate 23 are fixedly connected between the line straightening brackets 21. One side end face of the connecting vertical plate 22 is provided with a plurality of horizontal straightening wheels 24 arranged at intervals and staggered. The upper end face of the connecting flat plate 23 is provided with a plurality of vertical straightening wheels 25 arranged at intervals and staggered. The plurality of horizontal straightening wheels 24 and the plurality of vertical straightening wheels 25 are all tangent to the same straight line.

[0041] Multiple horizontal straightening rollers 24 and multiple vertical straightening rollers 25 can all adjust the clamping force via spring blocks. The horizontal and vertical straightening rollers 24 and 25 on the connecting plate 22 and connecting flat plate 23 are used to straighten curved metal lines.

[0042] As shown in Figure 5 and Figure 6 As shown, in this embodiment, the pressure roller feeding device 30 includes a mounting plate 31, three sets of wire feeding rollers 32 and a drive motor 33. Each set of wire feeding rollers 32 is arranged in parallel and is arranged opposite to each other on one side of the mounting plate 31. The drive motor 33 drives the wire feeding rollers 32 in each set to rotate in opposite directions through a gear transmission structure 34.

[0043] The metal wire is fed between three sets of wire feeding rollers 32. The drive motor 33 drives the wire feeding rollers 32 between each set to rotate in opposite directions through the gear transmission structure 34, thereby driving the metal wire to move between the three sets of wire feeding rollers 32.

[0044] like Figure 7 As shown in Figure 8, in this embodiment, the cutting and bending device 50 includes a mounting base 51, a cutting blade 52, a bottom blade 53, and a punch block 54. The mounting base 51 is connected to the frame 10 via a guide rail slider. The cutting blade 52 is positioned on the front side of the mounting base 51 via a stamping guide mechanism 55. The bottom blade 53 is connected to the lower side of the cutting blade 52. The bottom blade 53 is provided with a detachable feeding module 531, and the feeding module 531 has a through feeding hole 532 inside. The cutting blade 52 is provided with a notch 521 for bending. The punch block 54 is detachably connected to the front side of the mounting base 51 and is positioned opposite to the notch 521.

[0045] In practice, the mounting base 51 is connected to the frame 10 via a guide rail slider and is slidably adjusted by a cylinder. The cutting blade 52 can move vertically through the stamping guide mechanism 55 and, together with the bottom blade 53, cuts the metal lines coming out of the feed hole 532. At the same time, the notch 521 on the cutting blade 52, together with the punch block 54 set opposite to it, can bend the cut metal lines to form a shaped product.

[0046] In addition, the feeding module 531 is detachably connected to the bottom blade plate 53 to adapt to the cutting and bending of metal lines of different shapes.

[0047] In this embodiment, a movable punch 56 is provided above the punch block 54 on the mounting base 51, which is used to eject the cut and bent formed product from the punch block 54.

[0048] The metal product forming machine provided by this utility model, compared with the prior art, features a cutting and bending device 50 that can be slidably adjusted along the longitudinal direction of the frame 10. When the type of product requires a stamping and punching forming process, the cutting and bending device 50 can be slidably adjusted to avoid the discharge end of the stamping die 40. When the type of product requires a cutting and bending forming process, the cutting and bending device 50 can be adjusted to align with the feeding direction, allowing the metal wire to enter the cutting and bending device 50 through the material passage of the stamping die 40 for cutting and bending. This machine is applicable to the production processes of different product types, achieving a multi-purpose technical effect and effectively reducing equipment costs for enterprises, thus saving production costs.

[0049] Where there is no conflict, the above embodiments and features can be combined with each other.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
