[0023] The two transmission assemblies are arranged in an inverted V shape, and the middle part has a spacing, and the end of the lower pressing knife is located between the spacing to avoid the falling of the crushed material on the transmission belt, thereby reducing the wear of the transmission belt, and the crushed material is guided into the mounting groove to facilitate the cleaning of the crushed material.

[0033] Reference Figures 1-6 A press breaking machine for nickel-chromium wire production and processing, comprising:

[0034] The press breaking assembly 1 comprises a processing table 11 and an upper pressing knife 14, a mounting groove is formed in the middle of the processing table 11, and a transmission groove is formed on one side, the mounting groove and the transmission groove are vertically arranged in a T shape, two transmission assemblies 5 are symmetrically arranged inside the mounting groove, the upper pressing knife 14 is arranged directly above the mounting groove, the raw material is placed between the two transmission assemblies 5, so as to transfer the element, and the raw material is subjected to press breaking treatment by the upper and lower moving upper pressing knife 14;

[0035] The linkage assembly 2 comprises a mounting rod 21, a rotating sleeve 22, a first piston rod 23, a second piston rod 24 and a mounting block 25. The two mounting blocks 25 are L-shaped and symmetrically fixedly connected on the two sides of the breaking assembly 1. The mounting block 25 is internally provided with an L-shaped cavity. The first piston rod 23 is slidingly arranged in the vertical cavity of the mounting block 25. The second piston rod 24 is slidingly arranged in the horizontal cavity of the mounting block 25. The mounting rod 21 is connected to the upper pressing knife 14. The two rotating sleeves 22 are symmetrically and rotatably arranged on the two sides of the mounting rod 21 and fixedly connected with the upper end of the first piston rod 23. The downward movement of the upper pressing knife 14 drives the downward movement of the mounting rod 21 and the rotating sleeve 22, so that the first piston rod 23 slides in the vertical cavity, pushes the hydraulic liquid in the cavity, and drives the second piston rod 24 to change the position of the second piston rod 24. The upper pressing knife 14 drives the linkage assembly 2.

[0036] The extrusion assembly 3 comprises a threaded rod 31, a pressing plate 32 and a pressing block 33. The two pressing blocks 33 are fixedly connected to the side edges of the transmission groove and symmetrically arranged with the mounting groove as the axis. The second piston rod 24 is provided with a threaded groove at the end. The threaded rod 31 is threadedly arranged in the threaded groove. The pressing plate 32 is fixedly connected to the end of the threaded rod 31. When the second piston rod 24 moves outward, the pressing plate 32 moves, so that the raw material to be broken is fixed between the pressing plate 32 and the pressing block 33, and the position of the raw material is limited and fixed during the breaking process. At the same time, since the width of each raw material strip may be different, the position of the pressing plate 32 can be adjusted by rotating the threaded rod 31, so as to ensure the fixing effect of the raw material. The upper pressing knife 14 moves up and down to adjust the position of the second piston rod 24, so as to fix the raw material by the pressing plate 32 and the pressing block 33. After the breaking is completed, the fixing effect of the raw material is released, so as to ensure the normal transfer of the raw material.

[0037] In the embodiment of the application, the raw material is placed between the two transmission assemblies 5, so that the element is transferred, and the raw material is broken by the upper presser 14 moving up and down. When the upper presser 14 moves down, the mounting rod 21 and the rotating sleeve 22 move down, so that the first piston rod 23 slides in the vertical cavity, thereby pushing the hydraulic liquid in the cavity and pushing the second piston rod 24 to change the position of the second piston rod 24. The upper presser 14 moving up and down drives the linkage assembly 2. When the second piston rod 24 moves out, the pressing plate 32 moves, so that the raw material to be broken is fixed between the pressing plate 32 and the pressing block 33. The upper presser 14 moving up and down adjusts the position of the second piston rod 24, so that the pressing plate 32 and the pressing block 33 fix the raw material. After the breaking is completed, the fixing effect on the raw material is released, so that the raw material is normally transferred. The raw material can be fixed during the breaking process, so that the raw material is prevented from deviating during the processing, and the breaking efficiency is ensured.

[0038] In the preferred technical solution of the embodiment, the breaking assembly 1 further comprises a first cylinder 12, side frames 13, an upper presser 14, a second cylinder 15 and a lower presser 16. The first cylinder 12 is vertically fixedly connected in the mounting groove and located at one end of the mounting groove. The two side frames 13 are fixedly connected on both sides of the mounting groove. The upper presser 14 is rotatably connected to the upper end of the first cylinder 12 and rotatably connected to the two side frames 13 through a rotating shaft at the middle part.

When the first cylinder 12 moves up, the second cylinder 15 moves down. The lower presser 16 is rotatably connected to the second cylinder 15 at one end and rotatably connected to the inner wall of the mounting groove at the middle part. In the existing breaking machine, the breaking is usually performed from the upper side, which may cause damage to the lower processing surface. In order to ensure the breaking effect, the upper and lower pressers are used for breaking, so that the damage to the bottom side of the processing table 11 is avoided, and the breaking efficiency is improved and the processing speed is increased.

[0039] The adjusting assembly 4 comprises a fixed ring 41, an adjusting plate 42 and a middle shaft 43. The fixed ring 41 is fixedly sleeved on the moving end of the first cylinder 12.

The middle shaft 43 is arranged at the middle part of the adjusting plate 42 and rotatably connected between the two side frames 13. When the first cylinder 12 drives the upper presser 14 to move up at one end, the adjusting plate 42 moves up at one end, so that the lower presser 16 moves down at one end through the other end, and the upper presser 14 and the lower presser 16 can move simultaneously.

[0040] The transmission assembly 5 comprises a driving shaft 51 and a transmission belt 52, the two driving shafts 51 are symmetrically arranged in the transmission groove, and the transmission belt 52 is sleeved between the two driving shafts 51, and the two transmission assemblies 5 can quickly separate the raw material body and the broken raw material;

[0041] The pressing plate 32 is fixedly connected with a guide pushing assembly 6, and the guide pushing assembly 6 is used for separating the broken raw material. Since the positions of the raw material strips are relatively random when they are placed, and the positions will be offset after the pressing is completed, in order to ensure the limitation of the position of the raw material, the guide pushing assembly 6 is used for position limitation;

[0042] The guide pushing assembly 6 comprises a vertical shaft 61, a pushing plate 62 and an elastic pad 63, the vertical shaft 61 is vertically connected to the side of the two pressing plates 32 away from each other, one end of the pushing plate 62 is fixedly connected to the vertical shaft 61, and the elastic pad 63 is fixedly connected between the pushing plate 62 and the pressing plate 32. When the raw material strip is fixed, the pushing plate 62 will extrude the elastic pad 63, so that the elastic pad 63 is deformed, and the position of the raw material strip is fixed. When the pressing is completed, the pressing plates 32 on both sides are separated from the raw material, and the pushing plate 62 is deflected under the elastic force of the elastic pad 63, so as to separate the raw material blocks on both sides, avoid the position of the two raw material blocks being disconnected, and improve the feeding and the effect of limiting the position of the raw material;

[0043] The pushing plate 62 is made of a non-hard material, and forms an angle of 20°-45° with the pressing plate 32, and the elastic pad 63 is made of a low-deformation elastic material;

[0044] The pressing block 33 is fixedly connected with a plurality of extrusion strips 7, the plurality of extrusion strips 7 are arranged in parallel on the pressing block 33, and are made of an elastic material, so as to ensure the protection effect of the pressing block 33;

[0045] The two transmission assemblies 5 are arranged in an inverted V shape, and have a spacing in the middle, and the end of the pressing knife 16 is located between the spacing, so as to avoid that the broken material falls on the transmission belt 52 when the material is pressed, thereby causing greater wear of the transmission belt 52, and at the same time, the broken material is guided into the installation groove, so as to facilitate the cleaning effect of the broken material.

[0046] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
