Description

Technical Field

[0001] The present invention belongs to the technical field of metal cutting, and more particularly, relates to a cutting device for metal processing. Background Art

[0002] In the field of metal processing, cutting is a key process. Its processing accuracy, efficiency, and applicability directly affect product quality and production benefits. Currently, common metal cutting devices on the market have many shortcomings and cannot meet diverse processing needs.

[0003] Most traditional cutting devices have a relatively fixed workpiece clamping and positioning structure, enabling only simple horizontal fixation. For metal parts requiring multi-angle or tilted cutting, precise adjustment of position and angle is often impossible, resulting in low cutting accuracy and difficulty in processing complex metal parts. For example, when processing special-shaped metal structures in the aerospace industry, traditional devices often fail to meet the required tilted cutting angles, resulting in scrapped workpieces and increased production costs.

[0004] Existing cutting devices often rely on rigid clamping. When metal parts are irregularly shaped or require angled cutting, the clamping components cannot adaptively adjust their contact surface, leading to unstable clamping and workpiece shaking. This not only affects cutting quality but can also lead to safety accidents, such as metal parts slipping during cutting, damaging the cutting tool, and even threatening the operator's safety.

[0005] Furthermore, traditional cutting devices are cumbersome to adjust. Operations like height adjustment and angle positioning often rely on bolt fastening or complex mechanical structures, requiring multiple tools and time-consuming recalibration. This results in inefficient equipment changeovers and makes it difficult to adapt to the rapid processing needs of small batches of multi-specification metal parts. Furthermore, the user interface lacks intuitive guidance, requiring high operator skills, further limiting processing efficiency.

[0006] As the manufacturing industry develops towards high precision, high efficiency and intelligence, there is an urgent need for a metal cutting device that can flexibly adjust the cutting angle and position, stably clamp the workpiece and is easy to operate, in order to solve the technical bottlenecks of traditional equipment.

[0018] Compared with the prior art, the present application has the following beneficial effects:

[0019] 1. Multi-dimensional adjustment significantly improves cutting applicability: The present application can realize precise adjustment of the spatial position of metal parts in the horizontal, inclined and multi-angle space through the linkage adjustment of the translation plate, baffle and clamping plate. The lifting of the translation plate along the slide one and slide two, combined with the angle scale on the top and the horizontal rotation of the baffle, can meet the cutting needs of different inclined angles; when the translation plate is lifted to the highest position, the deflection can be realized through the cooperation of the state switching piece and the connecting screw, further expanding the cutting angle range. Compared with the traditional fixed station cutting device, the present application can increase the cutting applicable scene by more than 100%, especially suitable for the processing of complex special-shaped metal parts.

[0020] 2. Self-adaptive clamping structure ensures cutting stability: The ball hinge structure (ball and socket cooperation) is adopted between the threaded operating rod and the clamping plate, and the positioning of the arc-shaped insertion strip and the arc-shaped insertion groove makes the clamping plate automatically adjust the fitting surface with the angle change of the baffle. This design avoids the problem of unstable clamping when traditional rigid clamping is used for inclined cutting, even if the metal part is in irregular inclined state, it can also keep close fitting. Effectively improve cutting precision and yield.

[0021] 3. Quick positioning and fixing, improve processing efficiency: The positioning slot on the slide two cooperates with the sliding rod, the operator only needs to pull the lifting rod to quickly unlock or lock the height position of the translation plate, which saves the adjustment time compared with the traditional bolt fixing method. At the same time, the clamping plate is quickly fixed by extruding the threaded sleeve, the baffle realizes the quick locking of the angle by using the nut and the identification plate, the whole adjustment process does not need additional tools, which greatly shortens the changeover time and is suitable for efficient processing of small batch and multi-specification metal parts.

[0022] 4. Humanized operation design reduces labor intensity: The grip and connecting frame design on the fixed base, combined with the arc treatment of the state switching element, ensures a comfortable grip and convenient force application when adjusting the translation plate and clamping components. The conical marking block on the identification plate and the angle scale of the translation plate form a visual guide, allowing precise angle control without the need for auxiliary measurement tools, reducing operational difficulty. In addition, the anti-slip buffer layer on the opposite side of the clamping plate and the baffle ensures clamping force while preventing damage to the metal surface, balancing processing quality and operational safety.

In combination with the baffle 4 and the clamping plate 7 with adjustable deflection angle, and the translation plate 3 that can be deflected after rising to the highest point, the metal piece to be cut can be cut at different heights and angles, thereby improving the applicable range of cutting.

[0036] The bottom surface of the translation plate 3 is fixedly connected to two slides 19, and the bottom surfaces of the two slides 19 are fixedly connected with convex slide grooves 22, and the two slide grooves 22 are movably engaged with the two convex track rods 11. The structure composed of the translation plate 3 and the right slide 19 runs through two through grooves 23, and the two side surfaces of the right slide 19 are fixedly connected with shaft rods 24 and limit blocks 25. The two shaft rods 24 are rotatably connected with state switching parts 26, and the right end and the upper left end of the state switching parts 26 are both arc-shaped. The upper surface of the translation plate 3 is fixedly connected with a threaded column 20, and the left end of the translation plate 3 is also provided with a rod groove 21.

In a normal state, the lower end of the slide 19 is against the bottom plate 13, and the translation plate 3 is stuck in the operating groove 8 and is flush with the upper surface of the operating table 2. The metal part to be cut is placed between the baffle 4 and the splint 7. By rotating the screw rod 6, the baffle 4 and the splint 7 clamp the metal part. The opposite surfaces of the baffle 4 and the splint 7 are pasted with a layer of anti-slip buffer layer. At this time, the cutting machine can be controlled normally to cut the metal part.

[0037] The splint 7 is fixedly connected with a ball socket 32, and four arc-shaped inserts 33 are fixedly connected to the ball socket 32. The ball socket 32 ​​and the spherical member 34 form a ball hinge structure. The motion trajectory of the four arc-shaped inserts 33 corresponds to the cross-shaped arc slot 35.

A grip rod is fixedly connected between the two connecting frames 39. The bottom surface of the fixed seat 5 is provided with two inner cavities 40. The fixed seat 5 is provided with a screw groove 41. The screw groove 41 is connected to the threaded operating rod. The rod 6 is threadedly sleeved, and the bottom of the fixed seat 5 is fixedly connected to the translation plate 3. The inner top surfaces of the two inner cavities 40 are movably sleeved with sliding rods 42, and the two sliding rods 42 are sleeved with springs. The two sliding rods 42 are fixedly sleeved with baffles. The upper ends of the two sliding rods 42 are fixedly connected with lifting rods 43. The lower ends of the two sliding rods 42 pass through the through grooves 23 and are inserted into the positioning slots 12. When the metal parts need to be cut obliquely, the nut 27 is rotated so that it no longer presses against the identification plate 29. At this time, the baffle 4 can be rotated horizontally with the rotating shaft 31 as the axis. During the rotation, The deflection angle of the baffle 4 is determined by the angle mark of the conical marking block 28 and the left end of the translation plate 3 to ensure that the angle adjustment is accurate. After the baffle 4 is deflected, after the splint 7 continues to contact the metal part, the ball-and-socket structure is used to make the splint 7 fit the surface of the metal part again, so that the splint 7 can complete the cooperation with the baffle 4. During the deflection of the splint 7, the arc-shaped insert 33 is horizontally rotated and inserted into the corresponding arc-shaped slot 35. After the adjustment of the splint 7 is completed, the threaded sleeve 38 is rotated and squeezed to make it press against the arc-shaped insert 33 and the ball-and-socket 32 ​​in contact with it, so as to help The spring on the threaded rotating rod 37 plays an auxiliary role in fixing the position of the splint 7, effectively preventing the loosening of the squeezed threaded sleeve 38; when the metal parts need to be cut at multiple angles, the operator holds the grip between the two connecting frames 39, and then uses four fingers to pinch the lifting rod 43, pulls the slide bar 42 upward to disengage it from the positioning slot 12, and the slide plate 19 can now slide upward along the slide to increase the height of the translation plate 3. After the height is increased, the slide bar 42 can be inserted into the new positioning slot 12 to further improve the applicability.

[0038] Working principle:

[0039] When using this device, the operator can clamp the metal piece to be cut and adjust its height by moving the translation plate 3 and the threaded operating rod 6. In combination with the baffle 4 and the clamping plate 7 with adjustable deflection angle, and the translation plate 3 that can be deflected after rising to the highest point, the metal piece to be cut can be cut at different heights and angles, thereby improving the applicable range of cutting. The specific principle and operation process are as follows:

[0040] In the normal state, the lower end of the slide plate 19 is against the bottom plate 13, the translation plate 3 is stuck in the operating groove 8 and is flush with the upper surface of the operating table 2, the metal piece to be cut is placed between the baffle plate 4 and the clamping plate 7, and the baffle plate 4 and the clamping plate 7 are clamped by rotating the threaded operating rod 6. The opposing surfaces of the baffle plate 4 and the clamping plate 7 are both pasted with a layer of anti-slip buffer layer. At this time, the cutting machine can be controlled normally to cut the metal piece;

[0041] When the metal part needs to be cut obliquely, the nut 27 is rotated so that it no longer presses against the identification plate 29. At this time, the baffle 4 can be rotated horizontally with the rotating shaft 31 as the axis. During the rotation, the deflection angle of the baffle 4 is determined by the angle mark of the conical marking block 28 and the left end of the translation plate 3 to ensure that the angle adjustment is accurate. After the baffle 4 is deflected, the clamping plate 7 continues to contact the metal part, and the ball and socket structure is used to make the clamping plate 7 fit the surface of the metal part again, so that the clamping plate 7 can complete the cooperation with the baffle 4. During the deflection of the clamping plate 7, the arc insertion bar 33 is rotated horizontally and inserted into the corresponding arc slot 35. After the clamping plate 7 is adjusted, the threaded sleeve 38 is rotated to press it against the arc insertion bar 33 and the ball socket 32 ​​in contact with it, so as to achieve the effect of helping to fix the position of the clamping plate 7. The spring on the threaded rotating rod 37 plays an auxiliary role, effectively preventing the loosening of the threaded sleeve 38.

[0042] When a metal part needs to be cut at multiple angles, the operator holds the gripping rod between the two connecting frames 39, then pinches the lifting rod 43 with four fingers, pulls the sliding rod 42 upward to disengage it from the positioning slot 12, and then the slide plate 19 can slide upward along the slideway to raise the height of the translation plate 3. After the height is raised, the sliding rod 42 can be inserted into the new positioning slot 12, which can further improve the applicability.

[0043] When the translation plate 3 is lifted to the highest point, the convex track rod 11 disengages from the slide groove 22, and then the limit block 25 abuts against the connecting seat 18. At this time, the connecting screw 15 is rotated to connect it to the state switching member 26. At this time, the translation plate 3 can be deflected with the shaft 24 as the axis. The operator holds the handle well and exerts force. The deflected translation plate 3 can further improve the cutting application range. Pads of different thicknesses are placed on the bottom plate 13. The position of the translation plate 3 can be fixed by placing pads between the slideway and the slide plate 19.

Many modifications and variations will be apparent to those skilled in the art.
