Description

Technical Field

[0001] The present invention relates to the technical field of steel product processing, and in particular to a production and processing device for steel products. Background Art

[0002] Steel products are items made of steel, including but not limited to round steel pipes, square steel pipes, etc. Among them, according to the cross-section formation, they are further divided into square pipes and rectangular pipes. During the production and processing of steel products, a series of operations such as cutting, grinding, and welding will be carried out, and the cutting operation is the most common operation in the processing steps.

[0003] When using the existing technology to perform cutting processing operations on square steel pipes, a fixture tooling is used to limit and fix the square steel pipes. However, the existing fixture tooling can often only limit and clamp the square steel pipes from two directions. Since the square steel pipe itself has four different outer surfaces, the clamping method that can only be carried out from two directions will cause the outer surfaces of the other two directions to lack corresponding limiting measures, so there is a problem of poor limiting performance and cannot meet the use requirements. Although there are also some toolings in the existing technology that can apply limiting clamping from four directions simultaneously, they can often only be applied to the clamping and limiting work of square pipes. Because the length and width of square pipes are the same, the fixture only needs to clamp inward from four directions synchronously to achieve the clamping operation. However, the length and width of rectangular pipes are different. For the fixture that clamps inward from four directions synchronously, only the fixtures in two of the four directions can clamp the rectangular pipe, so the other two directions of the rectangular pipe still lack limiting measures and cannot meet the use requirements. At the same time, the existing fixing methods often only apply limiting to both sides of one end of the steel product, and no separate limiting and fixing is carried out on the other end. Therefore, when the cutting blade contacts the steel product, under the action of the stress generated by the two and the gravity of the steel product itself, the end without limiting is prone to offset and fall phenomena, which will seriously affect the working effect of the cutting work.

Detailed implementation manners

[0025] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Refer to Figures 1 to 8 , which is an embodiment of the present invention, including a production and processing device for steel products, including a base 1, two groups of clamping units 2 symmetrically arranged on the base 1, a driving unit 3 arranged on the side of the clamping unit 2, and a cutting unit 4 located on the other side of the clamping unit 2. The clamping unit 2 is used to clamp and limit the steel products, the driving unit 3 is used to drive the clamping unit 2 to work, and the cutting unit 4 is used to cut the steel products. By setting two groups of clamping units 2 and fixing both ends of the steel products to be cut from both sides at the same time, it can effectively avoid phenomena such as deflection and falling of the steel products during the cutting process, and effectively ensure the steady progress of the cutting work. Refer to Figure 2 , the clamping unit 2 includes a fixing component 22 arranged on the base 1, multiple groups of clamping components 23 arranged in the fixing component 22, multiple groups of connecting components 24 arranged on the fixing component 22 and corresponding to the multiple groups of clamping components 23 one by one, and an internal gear ring 25 sleeved on the fixing component 22. The inner side of the internal gear ring 25 meshes with the connecting component 24, the internal gear ring 25 is rotatably connected to the fixing component 22, four groups of clamping components 23 are slidably inserted into the fixing component 22, and the inner sides of the four groups of clamping components 23 are distributed in a parallelogram. Refer to Figure 3 , multiple groups of guide grooves 223 are evenly distributed on the side of the fixing component 22, and the directions of every two adjacent guide grooves 223 are perpendicular to each other. Multiple groups of fixing shafts 226 are evenly distributed on the outer diameter of the fixing component 22. The guide grooves 223 define the moving direction of each clamping component 23, and the fixing shafts 226 are used to install the connecting component 24. Refer to Figure 4, the clamping member 23 includes a clamping block 231 inserted into the fixing member 22, a rack 232 opened on one side of the clamping block 231, and a guide block 233 provided on the side of the clamping block 231. The guide block 233 is slidably connected to the guide groove 223. The way the guide block 233 extends into the guide groove 223 makes the whole clamping member 23 only able to move horizontally in the direction of the guide groove 223. The way the four groups of clamping members 23 move along the four groups of guide grooves 223 will make the hypotenuses of the four groups of clamping members 23 approach or move away from each other, thereby forming an operation of synchronously clamping inward or releasing outward to stop clamping; Refer to Figure 5 And Figure 6 , the connecting member 24 includes a main gear 241 and a sub-gear 242 sleeved on the fixed shaft 226. The sides of the main gear 241 and the sub-gear 242 are clamped. At the same time, the main gear 241 and the sub-gear 242 are respectively meshed and driven with the internal gear ring 25 and the rack 232. And a spring 243 provided outside the main gear 241. The main gear 241 and the sub-gear 242 can rotate around the fixed shaft 226 as the axis. The spring 243 firmly connects the main gear 241 and the sub-gear 242 through elastic support, so that the two can rotate synchronously. The rotating sub-gear 242 drives the clamping member 23 to move and perform a clamping operation.

[0028] Furthermore, refer to Figure 3 , the fixing member 22 further includes a fixing ring 221 in a circular ring structure, and the guide groove 223 is opened on the side of the fixing ring 221. A relief groove 222 opened in the fixing ring 221, and the clamping member 23 is inserted into the relief groove 222. Multiple groups of limit pieces 224 provided on the outer wall of the fixing ring 221, and the internal gear ring 25 is rotationally connected to the fixing ring 221 through the limitation of the limit pieces 224. And multiple groups evenly distributed on the fixing ring 221 and corresponding to the multiple groups of fixed shafts 226 one by one mounting grooves 225. At the same time, the connecting member 24 is arranged in the mounting groove 225. The circular ring structure of the fixing ring 221 can facilitate the steel product to pass through it, and the relief groove 222 can provide a space for the installation and movement of the clamping member 23. The limit pieces 224 are used to limit and install the internal gear ring 25, so that the internal gear ring 25 can rotate axially without changing its position on the fixing member 22. The mounting groove 225 is a place for installing and fixing the connecting member 24.

[0029] Furthermore, refer to Figure 4, the clamping member 23 is integrally in a right triangle structure, and the rack 232 is provided on the longer right-angled side. The longest side of each group of clamping members 23 faces inward, and a clamping plate 234 is provided on the outer side of the longest side of each group of clamping members 23. The part of the clamping plate 234 in contact with the steel product can further increase the contact area with the steel product and further enhance the clamping stability.

[0030] Further, referring to Figure 4 , there are four groups of clamping members 23. Two groups of clamping members 23 in opposite directions form a pair of combinations. The two pairs of combinations formed by the four groups of clamping members 23 are mutually offset in the vertical direction. The offset setting method can prevent the four groups of clamping members 23 from blocking each other, enabling the four groups of clamping members 23 to smoothly perform sliding operations, enabling the four groups of clamping members 23 to perform more extreme closing, and meeting more usage requirements.

[0031] Further, referring to Figure 5 , a main clamping gear 2411 is provided inside the main gear 241, and a sub-clamping gear 2421 that meshes with the main clamping gear 2411 is provided on the side of the sub-gear 242. The tooth edges of the main clamping gear 2411 and the sub-clamping gear 2421 are smoothly transitioned. At the same time, the thickness of the main gear 241 is greater than the thickness of the sub-gear 242. The tooth edges of the main clamping gear 2411 and the sub-clamping gear 2421 are smooth, and they are clamped together in the circumferential direction, thereby connecting the main gear 241 and the sub-gear 242 together, enabling the main gear 241 and the sub-gear 242 to rotate synchronously. At the same time, when the force driving the main clamping gear 2411 to rotate is relatively large and the sub-clamping gear 2421 stops rotating, the main clamping gear 2411 and the sub-clamping gear 2421 will be misaligned through the guidance of the hypotenuse of the teeth, thereby disconnecting the connection between the main gear 241 and the sub-gear 242. The thicker main gear 241 can enable the main gear 241 to always remain meshed with the internal gear ring 25.

[0032] Among them, referring to Figure 7 , the internal gear ring 25 is rotatably sleeved on the fixing member 22, and teeth meshing with the main gear 241 are provided inside the internal gear ring 25. A connecting ear 251 is provided on the internal gear ring 25, and the connecting ear 251 is connected to the driving unit 3. The internal gear ring 25 is driven by the driving unit 3 through the connecting ear 251. Through the meshing of the teeth of the internal gear ring 25 with the main gear 241, the internal gear ring 25 can drive the main gear 241 to rotate, thereby enabling the rotating main gear 241 to drive the sub-gear 242 to rotate synchronously. The rotating sub-gear 242 then drives the clamping member 23 to move through meshing with the rack 232.

[0033] Furthermore, the clamping unit 2 further includes a fixing frame 21 fixedly connected to the base 1 , and the fixing component 22 is fixedly connected to the fixing frame 21 , and the clamping unit 2 is fixedly mounted on the base 1 via the fixing frame 21 .

[0034] Among them, refer to Figure 1 A slide rail 11 is provided on the base 1, and the cutting unit 4 is slidably connected in the slide rail 11. The base 1 is a base for fixing the entire device, and the slide rail 11 is used to install the cutting unit 4 and provide a limiting guide for the movement of the cutting unit 4.

[0035] Among them, refer to Figure 1 The driving unit 3 includes a telescopic cylinder 31 arranged on the base 1, a fixed base 32 fixedly connected to the base 1, and the end of the telescopic cylinder 31 is rotatably connected to the fixed base 32, and a connecting frame 33 transversely arranged at the top of the telescopic cylinder 31, and the connecting frame 33 extends outward and is inserted into the edge of the inner gear ring 25. The telescopic cylinder 31 drives the inner gear ring 25 to rotate around the fixed component 22 as the axis through the telescopic operation, and synchronously controls the inner gear rings 25 on the two groups of clamping units 2 to work through the transversely arranged connecting frame 33, thereby realizing the synchronous driving of the two groups of clamping units 2 to perform the clamping and limiting operation.

[0036] Among them, refer to Figure 7 The cutting unit 4 includes a slide 41 slidably connected to the slide rail 11, a motor 42 arranged at the top of the slide 41, and a cutting disc 43 arranged on the side of the motor 42. The cutting unit 4 can slide along the slide rail 11 through the slide 41 to perform a cutting operation. It can be seen from the cutting disc 43 that the cutting unit 4 is a device that uses a circular saw blade for cutting.

[0037] In summary, refer to Figure 7 When the square tube 5 is processed by the device, the steel product (square tube 5) to be cut is placed in the clamping unit 2 so that the steel product is located between the four clamping components 23. The driving unit 3 is started to work, and the telescopic cylinder 31 contracts and drives the inner gear ring 25 to rotate counterclockwise with the fixed component 22 as the axis. The counterclockwise rotating inner gear ring 25 drives the connecting component 24 to rotate as a whole through the teeth. The rotating connecting component 24 drives the clamping component 23 through the meshing of the pinion 242 and the rack 232. The four groups of clamping parts 23 move, and the clamping parts 23 slide along the guide groove 223 through the guide block 233. The four groups of clamping parts 23 move synchronously, and the movement directions of the four groups of clamping parts 23 are different, so as to form a staggered inward embracing operation, thereby achieving the operation of embracing and clamping the steel product. The four groups of clamping parts 23 can clamp the steel product (square tube 5) inward synchronously from four directions, so as to achieve multi-directional limit fixation of the steel product, strengthen the limit effect, and provide stable support for the cutting operation; Meanwhile, the range surrounded by the four groups of clamping components 23 for clamping is adjusted correspondingly according to the rotation amplitude of the clamping components 23. Therefore, by controlling the rotation amplitude of the internal gear ring 25, the distance between each other can be adjusted according to actual needs, so as to form different surrounded clamping ranges, and further meet the needs of clamping and limiting steel products of different sizes, improving the flexibility of device use; Refer to Figure 8 , when processing the rectangular tube 6 with this device, the operation is the same as the above operation. The difference is that for the four groups of clamping components 23 that move and perform clamping operations, two groups of clamping components 23 in opposite directions will preferentially contact the shorter sides of the rectangular tube 6 and firmly clamp on the shorter sides of the rectangular tube 6 with the drive of the internal gear ring 25. At this time, the two groups of clamping components 23 cannot move any further, and then limit the corresponding connecting components 24 in the reverse direction, making the corresponding connecting components 24 unable to rotate any further. At this time, the main gears 241 of the non-rotatable connecting components 24 still rotate with the rotation of the internal gear ring 25, while the corresponding secondary gears 242 cannot rotate. At this time, the main engaging gears 2411 and the secondary engaging gears 2421 between the main gears 241 and the secondary gears 242 are misaligned, causing the main gears 241 to compress the springs 243. At this time, the main gears 241 move along the fixed shafts 226 and no longer drive the secondary gears 242 to rotate. At this time, the main gears 241 can rotate independently, thus not hindering the internal gear ring 25 from driving the other two groups of connecting components 24 to move. The continuously rotating internal gear ring 25 will drive the other two groups of clamping components 23 to clamp on the longer sides of the rectangular tube 6, realizing the fixation of the other two sides of the rectangular tube 6. Through the operation, it can be seen that the device can adjust the clamping range between every two groups of clamping components 23 according to the length and width of the steel product, so that the device can meet the operation of clamping and limiting steel products of different shapes, further enhancing the flexibility of device use.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
