Description

Technical Field

[0001] This utility model relates to the field of flattening machine technology, specifically a flattening machine with adjustable range. Background Technology

[0002] Flattening machines are widely used in metal processing, sheet metal forming and other fields to apply pressure to the surface of workpieces to achieve a flattening effect;

[0003] Traditional flattening machines typically use fixed-size pressure plates or integral flattening structures, resulting in a fixed flattening range that cannot flexibly adapt to workpieces of different sizes or shapes. Changing molds is also time-consuming and labor-intensive. Secondly, uneven pressure distribution leads to local deformation or insufficient overall flatness. At the same time, the adjustment mechanism is complex, relying heavily on overall lifting or manual positioning, which results in low adjustment accuracy and low efficiency, presenting obvious limitations. Therefore, a new technical solution needs to be designed to address these issues. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] In this technical solution, an adjustable flattening machine includes a base plate 1 and a support platform 2. The support platform 2 is fixedly installed on the upper end of the base plate 1. Two uprights 3 are installed on both sides of the rear end of the base plate 1. An adjustable flattening structure is installed on the upper end of the two uprights 3. The adjustable flattening structure includes a top plate 4, a hydraulic cylinder 5, an operating frame 6, a mounting frame 7, two guide sleeves 8, and a flattening assembly.

[0024] The top plate 4 is fixedly installed on the top of the two uprights 3. The hydraulic cylinder 5 is fixedly installed on one side inside the top plate 4. The upper center of the operating frame 6 is connected to the telescopic end of the hydraulic cylinder 5. The mounting frame 7 is fixedly installed on the lower end of the operating frame 6. The two guide sleeves 8 are respectively installed on both sides of the rear end of the mounting frame 7. The two guide sleeves 8 are respectively movably fitted onto the upper ends of the two uprights 3. The flattening component is installed inside the operating frame 6 and the mounting frame 7.

[0025] In this technical solution, when flattening materials, the operator first moves the device to the designated position, supports it with the base plate 1, and connects it to the designated control system. Then, according to the specifications of the material and the flattening requirements, the flattening components are adjusted, and the material is placed on the upper end of the support platform 2. Subsequently, the hydraulic cylinder 5 on the upper end of the top plate 4 is driven to work, pushing the operating frame 6 and the mounting frame 7 downward. Under the sliding connection between the two guide sleeves 8 and the uprights 3, the descent of the mounting frame 7 and the flattening components is ensured to be stable. The flattening components cooperate with the support platform 2 to flatten the material.

[0026] In some technical solutions, reference Figure 1 The flattening assembly includes a fixed plate 9, four threaded sleeves 10, eight guide blocks 11, eight guide rods 12, four adjusting screws 13, four connecting plates 14, and four pressing plates 15.

[0027] The two ends of the fixed plate 9 are fixedly connected to the inner sides of the operating frame 6, respectively. Four threaded sleeves 10 are evenly embedded in the fixed plate 9. Eight guide blocks 11 are installed on both sides of the fixed plate 9, and eight guide rods 12 are movably embedded in the eight guide blocks 11. Four adjusting screws 13 are movably embedded in the four threaded sleeves 10. The upper center of the four connecting plates 14 is movably connected to the bottom of the four adjusting screws 13, and the upper sides are fixedly connected to the bottom of the eight guide rods 12. Four pressure plates 15 are installed on the lower end of the four connecting plates 14, and are movably embedded in the mounting frame 7.

[0028] In this technical solution, when faced with materials requiring different flattening, the operator sequentially turns the four adjusting screws 13 inside the four threaded sleeves 10. Under the meshing action of the adjusting screws 13 and the threaded sleeves 10, the four connecting plates 14 are driven to rise and fall respectively. At the same time, with the cooperation of the eight guide blocks 11 and the eight guide rods 12, the adjustment stability of the four connecting plates 14 and the pressing plate 15 is ensured. Finally, under the push of the hydraulic cylinder 5, the designated pressing plate 15 is brought into contact with the support table 2 to flatten the material.

[0029] In some technical solutions, reference Figure 1 The position where the upright 3 connects to the base plate 1 is machined with a first reinforcing rib 16, the position where the guide sleeve 8 connects to the mounting frame 7 is machined with a second reinforcing rib 17, the operating frame 6 is a U-shaped operating frame 6, the position where the connecting plate 14 connects to the adjusting screw 13 is machined with a bearing seat 18, and the position where the operating frame 6 connects to the hydraulic cylinder 5 is machined with a connecting plate 19.

[0030] By significantly improving the bending and torsional resistance, it ensures no structural deformation during hydraulic pressing. The symmetrical rigidity of the U-shaped operating frame 6 effectively resists lateral forces and prevents pressure deviation. The bearing seat 18 provides a movable connection to the bottom end of the adjusting screw 13 while reducing friction, ensuring smooth adjustment and service life. The hydraulic cylinder 5 is fixedly connected to the operating frame 6 via the connecting plate 19, ensuring the stability of the force transmission path.
