Description

Technical Field

[0001] This utility model belongs to the field of metal rolled material extrusion processing technology, and more specifically, it relates to a cutting device for non-ferrous metal rolled material extrusions. Background Technology

[0002] Non-ferrous metal rolled extrusions are materials that are pressure-processed using the principle of metal plastic forming. After the production of non-ferrous metal rolled extrusions is completed, cutting equipment is needed to cut the non-ferrous metal rolled extrusions into specified lengths for subsequent processing and use.

[0003] Existing cutting devices require manual adjustment of position after each cut, resulting in low automation and insufficient positioning accuracy. They rely heavily on manual measurement or simple mechanical limits, making it difficult to meet the requirements of high-precision cutting and leading to excessive length errors in extruded parts. At the same time, rigid clamping mechanisms are prone to causing indentations or scratches on the surface of non-ferrous metals, affecting the appearance quality of the product. Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a cutting device for extruded non-ferrous metal rolled materials, aiming to achieve a more practical purpose.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a cutting device for extruded non-ferrous metal rolled materials, including a cutting table 1. A feeding roller conveyor 2 is provided on one side of the cutting table 1, and a discharging roller conveyor 3 is provided on the other side of the cutting table 1. A U-shaped frame 4 is vertically installed at the top of both the feeding roller conveyor 2 and the discharging roller conveyor 3, and both sets of U-shaped frames 4 are close to one side of the cutting table 1. A clamping mechanism is provided inside the U-shaped frame 4. A connecting frame 5 is installed at the top of the cutting table 1. A through groove is opened in the horizontal section of the connecting frame 5. A guide plate 6 is slidably connected inside the through groove. A side plate 7 is installed at the top of the through groove. A sliding groove is opened at the bottom of the side plate 7. A driving mechanism for driving the guide plate 6 to move is provided inside the sliding groove. A fixed plate 8 is connected to the bottom of the guide plate 6. A drive shaft is rotatably connected to one side of the fixed plate 8. A saw blade 9 is fixedly installed on one side of the drive shaft. A geared motor 10 is coaxially connected to the other end of the drive shaft.

[0027] The drive mechanism includes a lead screw 11 installed in a slide groove. A ball nut is installed on the outside of the lead screw 11, and a slider that is slidably connected to the slide groove is installed on the outside of the ball nut. The slider is fixedly connected to one side of the guide plate 6. A second geared motor 13 is installed on the outside of the side plate 7. The output end of the second geared motor 13 extends into the slide groove and is coaxially connected to the lead screw 11, ensuring the smoothness of the lateral movement of the saw blade 9 and the consistency of the cutting length. At the same time, the second geared motor 13 is directly connected to the lead screw 11, which simplifies the transmission chain and reduces maintenance costs.

[0028] The clamping mechanism includes an electric pusher cylinder 14 installed at the top of the two vertical sections of the C-shaped frame 4. Guide grooves are provided in both vertical sections of the C-shaped frame 4. The output end of the electric pusher cylinder 14 extends into the guide groove and is equipped with a connecting block 15. A rubber roller 16 is rotatably connected between the two sets of connecting blocks 15. A reduction motor 3 17 is installed on the outer side of one set of connecting blocks 15, and the output end of the reduction motor 3 17 is fixedly connected to the rotation shaft of the rubber roller 16. The elastic material of the rubber roller 16 prevents indentations on the non-ferrous metal surface, improving the processing pass rate. Simultaneously, the reduction motor 3 17 drives the rubber roller 16 to rotate, assisting in the extrusion feeding and solving the problem of traditional clamping mechanisms only providing positioning without driving. The electric pusher cylinder 14 can automatically adjust the clamping force according to the thickness of the extrusion, thus making it suitable for non-ferrous metal materials of different thicknesses.

[0029] Two sets of electric push cylinders 18 are symmetrically installed at the top of the feeding roller conveyor 2 and on the side near the corresponding C-shaped frame 4. The output ends of the two sets of electric push cylinders 18 on the same side are connected to clamping plates 19. Rubber pads are provided on one side of the two sets of clamping plates 19, which can drive the clamping plates 19 to clamp synchronously, eliminate the offset during extrusion cutting, and control the length error. The rubber pads cover the surface of the clamping plates 19 to avoid scratches caused by rigid contact, which is especially suitable for easily damaged non-ferrous metals.

[0030] The top of the feeding roller conveyor 2 and the side near the corresponding shaped frame 4 are each equipped with a grating ruler 12. The grating ruler 12 can monitor the feed displacement of the extruded part in real time, so as to meet the needs of different cutting lengths. Compared with the mechanical limit method, it improves the measurement accuracy and reduces the manual calibration steps.

[0031] The cutting table 1 has a slag-leakage groove at its top and directly below the saw blade 9, and a collection box 20 is installed at its bottom and directly below the slag-leakage groove. The vertical connection between the slag-leakage groove and the collection box 20 improves the waste chip collection rate and avoids waste chip accumulation from affecting the cutting accuracy.

[0032] The guide plate 6 has two sets of electric push cylinders 21 installed at its bottom end, and the output ends of both sets of electric push cylinders 21 are connected to the fixed plate 8. Two sets of guide rails 22 are fixedly installed on one side of the guide plate 6, and a limit block 23 is fixedly installed on one side of the fixed plate 8 and slidably connected to the guide rails 22. The electric push cylinders 21 drive the saw blade 9 to feed vertically, thereby adjusting different cutting depths to adapt to materials of different thicknesses. The sliding cooperation between the guide rails 22 and the limit block 23 eliminates the shaking of the saw blade 9 when it rises and falls, improving the stability of the device. At the same time, it can also limit the lowest position of the saw blade 9 to prevent overfeeding from causing equipment damage or safety accidents.

[0033] The working principle of this embodiment:

[0034] In operation, the non-ferrous metal extrusion is first placed on the feeding roller conveyor 2 and transported to the cutting area. Simultaneously, electric pusher cylinder 18 is activated, pushing clamping plates 19 to clamp the extrusion from both sides. Rubber pads provide flexible contact protection for the extrusion. Electric pusher cylinder 14 is then activated, pushing connecting block 15 downwards, causing rubber roller 16 to press against the upper surface of the extrusion. Next, reduction motor 17 is activated, driving rubber roller 16 to rotate, thus assisting in the feeding of the extrusion. Subsequently, grating ruler 12 is activated to monitor the front end position of the extrusion in real time. When the pre-set position is reached... When the cutting length is set, the second reduction motor 13 starts and drives the lead screw 11 to move the guide plate 6 horizontally, adjusting the saw blade 9 to the preset cutting starting point. The first reduction motor 10 drives the saw blade 9 to rotate at high speed, and the third electric pusher cylinder 21 pushes the fixed plate 8 down, so that the saw blade 9 cuts vertically into the extruded part. At the same time, the second reduction motor 13 drives the lead screw 11 to rotate and drives the saw blade 9 to feed laterally along the through groove to complete the cutting action. The waste generated by cutting falls into the collection box 20 through the slag leakage trough. After the cutting is completed, the third electric pusher cylinder 21 drives the saw blade 9 to rise and reset, and the unloading roller conveyor 3 sends out the finished part, ready for the next cutting cycle.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
