Description

Technical Field

[0001] The present invention relates to the technical field of metal rolling, and in particular to a rolling method for rolled products of black hardware metal smelting. Background Art

[0002] During the rolling process, when the material passes through the gap between the rolling rollers, it will be simultaneously affected by shear force and tensile stress. The polymer will be oriented along the rolling direction, so that the product has anisotropic characteristics in physical mechanics. The rolling effect causes differences in the performance of the product. One of them is that the longitudinal (along the rolling direction) tensile strength of the rolled film (sheet) is greater than the transverse tensile strength, so that the transverse elongation at break is greater than the longitudinal. When the use temperature changes too much, the dimensions in each direction will change. The longitudinal direction will shrink, and more seriously, it will break. At this time, the transverse and thickness directions will expand, which is the anisotropy of the product in physical mechanics.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Embodiment 1 As Figure 1-15 shown, a device for implementing a rolling method for a black hardware metal smelting and rolling product is provided. The device includes a conveying mechanism 1, an oiling mechanism 2, a rolling mechanism 3, and a cleaning mechanism 4; The rolling mechanism 3 includes a frame 31, and a rolling component 32 horizontally movably arranged on the frame 31, and a power component 33 arranged on the frame 31 and used for driving the rolling component 32 to reciprocate; The rolling component 32 includes: A rolling frame 321, the rolling frame 321 is rotatably arranged on the frame 31 through a plurality of groups of rollers 322, the rolling rolls 323 are divided into two groups and are respectively rotatably arranged inside the rolling frame 321 through rotating shafts, and the two rotating shafts are synchronously driven through passive gears 324; A driving gear 325, the driving gear 325 is arranged at the end of one of the rotating shafts, and a rack 326 for driving the driving gear 325 is arranged on the frame 31; The spray head 327 is inclined and arranged on the frame 31 and is used to spray coolant onto the rolling rolls 323 and the pipe. A recovery box 328 for collecting the coolant is arranged on the frame 31. The coolant inside the recovery box 328 is filtered and then sucked back to the spray head 327 through an existing water pump for recycling. The feed inlet 329 is opened on one side surface of the frame 31, and a discharge outlet 3291 for the pipe to output is opened on the other side surface of the frame 31. The power assembly 33 includes: The turntable 331 is rotatably arranged on the frame 31. The turntable 331 is divided into two groups and is synchronously driven by a coupling shaft. A first driving member 332 for driving the turntable 331 is arranged on the frame 31. The crank 333 is hinged on the turntable 331. The turntable 331 drives the rolling frame 321 to reciprocate on the frame 31 through the crank 333. Protrusions are arranged on both the turntable 331 and the rolling frame 321. The collar at both ends of the crank 333 is respectively sleeved on the two protrusions.

[0036] It should be noted that the first driving member 332 adopts an existing stepping motor.

[0037] In this embodiment, through the cooperation of the rolling assembly 32 and the power assembly 33, the pipe is automatically rolled in sequence, and coolant is sprayed to cool the pipe and the rolling rolls, avoiding deformation of the rolling rolls due to high-temperature thermal expansion and affecting the rolling effect of the pipe.

[0038] Specifically, the pipe enters from the feed inlet 329. The first driving member 332 drives the turntable 331 to rotate. The turntable 331 drives the rolling frame 321 to reciprocate horizontally on the frame 31 through the crank 333, so that the rack 326 drives the driving gear 325 at the end of the rotating shaft to rotate. The rotating shaft drives the two rolling rolls 323 to rotate synchronously through the driven gear 324. The two rolling rolls 323 perform rolling work on the pipe. The spray head 327 sprays coolant to cool the pipe and the rolling rolls. The recovery box 328 collects the coolant for reuse. The rolled pipe is output from the discharge outlet 3291.

[0039] Further, as Figure 1 and Figure 5 shown, the conveying mechanism 1 is divided into two groups and is respectively arranged on both sides of the rolling assembly 32. It includes a conveying frame 11, a positioning assembly 12 arranged on the conveying frame 11 and used for clamping and positioning the mandrel 6, and a feeding assembly 13 arranged on the conveying frame 11 and used for driving the pipe 7 to move forward. The positioning component 12 includes a gantry 121 arranged on the conveying rack 11, a first hydraulic component 122 arranged on the gantry 121, and an electric gripper 123 arranged at the output end of the first hydraulic component 122 and used for clamping the mandrel; The feeding component 13 includes two groups of threaded rods 131 symmetrically arranged on both side surfaces of the conveying rack 11, moving blocks 132 threadedly arranged on the threaded rods 131, a second hydraulic component 133 arranged on the moving blocks 132, anti-slip clamping blocks 134 arranged at the output end of the second hydraulic component 133 and used for clamping the pipe, and a second driving component 135 arranged on the conveying rack 11 and used for driving the threaded rod 131.

[0040] It should be noted that the second driving component 135 adopts an existing stepping motor.

[0041] It is worth mentioning that the structure and function of the electric gripper 123 are both prior arts and will not be elaborated here.

[0042] It also needs to be noted that when the pipe starts to be sleeved on one end of the mandrel close to the feed port 329, the electric gripper 123 close to the feed port 329 releases the mandrel for avoidance, and the electric gripper 123 close to the discharge port 3291 clamps and supports the mandrel to maintain the original position for positioning; similarly, when the rolled pipe starts to leave the mandrel, the electric gripper 123 close to the discharge port 3291 releases the mandrel for avoidance, and the electric gripper 123 close to the feed port 329 clamps and supports the mandrel to maintain the original position for positioning.

[0043] It is also worth mentioning that the two anti-slip clamping blocks 134 of the feeding component 13 alternately drive the pipe to be intermittently conveyed forward, ensuring that the two anti-slip clamping blocks 134 alternately return, so as to automatically drive the pipe to be conveyed forward in sequence.

[0044] In this embodiment, through the cooperation of the arranged positioning component 12 and feeding component 13, the mandrel can be clamped and positioned, ensuring that the mandrel stably supports the pipe and is coaxial with the pipe, and driving the pipe to be intermittently conveyed forward to sequentially carry out the rolling work.

[0045] Specifically, the first hydraulic component 122 drives the electric gripper 123 to descend, the electric gripper 123 clamps and positions the electric gripper 123, and during the process of the pipe being sleeved on and separated from the mandrel, the two electric grippers 123 respectively avoid the advancing pipe. The second hydraulic component 133 drives the anti-slip clamping block 134 to clamp the outer wall of the pipe, and the second driving component 135 drives the moving block 132 with the anti-slip clamping block 134 to move through the threaded rod 131, so that the anti-slip clamping block 134 drives the pipe to move forward. After the anti-slip clamping block 134 releases the pipe, it returns, and the two anti-slip clamping blocks 134 alternately drive the pipe to move forward.

[0046] Embodiment Two As Figure 1-Figure 2 and Figure 6-Figure 12 shown, where the same or corresponding components as in the first embodiment are provided with the corresponding reference numerals of the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The differences between the second embodiment and the first embodiment are as follows: As Figure 6-Figure 9 shown, the oiling mechanism 2 includes a rope tightening assembly 22 provided on the frame 31 and used for tightening the cotton rope 21 to wrap the pipe, a rope dipping assembly 23 provided on the frame 31 and used for dipping the cotton rope 21 in oil, and a weight dropping assembly 24 provided inside the rope dipping assembly 23 and used for driving the cotton rope 21 to descend; The rope tightening assembly 22 includes: An installation frame 221, the installation frame 221 is provided on the frame 31, a bidirectional lead screw 222 is rotatably provided on the installation frame 221, two groups of hollow blocks 223 are symmetrically threaded on the bidirectional lead screw 222, and a third driving member 224 for driving the bidirectional lead screw 222 is provided on the installation frame 221; A hanging block 225, the hanging block 225 is slidably and vertically arranged inside the hollow block 223, a first elastic member 226 is arranged between the hanging block 225 and the hollow block 223, and the cotton rope 21 winds around the pipe for one circle and its two ends are respectively connected to the two hanging blocks 225; A hanging rod 227, the hanging rod 227 is provided on the hanging block 225, and a first limiting track 228 for driving the hanging rod 227 to drive the hanging block 225 to descend is provided on the frame 31.

[0047] It should be noted that the third driving member 224 adopts an existing stepping motor.

[0048] It is worth mentioning that since the pipe is intermittently conveyed forward, when the pipe advances, the cotton rope 21 wraps the outer wall of the pipe for cleaning and impurity removal. When the pipe stays, the cotton rope 21 loosens the outer wall of the pipe and descends into the oil storage tank 231 to replenish lubricating oil.

[0049] It is also worth mentioning that the first limiting track 228 drives the hanging rod 227 to drive the hanging block 225 to descend, so that the two ends of the cotton rope 21 descend, making the cotton rope 21 tighten more tightly around the top of the pipe, ensuring that the cotton rope 21 tightly wraps the outer wall of the pipe in all directions and facilitating the cotton rope 21 to clean foreign matters on the outer wall of the pipe.

[0050] In this embodiment, by the cooperation of the provided rope tightening assembly 22 and rope dipping assembly 23, foreign matters on the outer wall of the pipe can be automatically cleaned, and lubricating oil can be coated on the outer wall of the pipe, ensuring the cleanliness of the pipe surface, improving the lubrication degree of the pipe surface, avoiding damage to the pipe surface by foreign matters, and improving the calendering effect of the pipe.

[0051] Specifically, after the pipe enters from the feed port 329, when the pipe advances, the third driving member 224 drives the two hollow blocks 223 away from each other through the bidirectional lead screw 222, so that the cotton rope 21 gradually clamps the outer wall of the pipe. When the hanging rod 227 moves to the first limiting track 228, the first limiting track 228 drives the hanging rod 227 to drive the hanging block 225 to descend, so that the two ends of the cotton rope 21 descend, and the cotton rope 21 tightly wraps the outer wall of the pipe in all directions; when the pipe stays, the third driving member 224 drives the two hollow blocks 223 to approach each other through the bidirectional lead screw 222, so that the cotton rope 21 loosens the pipe, and the cotton rope 21 descends into the oil storage tank 231 to replenish lubricating oil.

[0052] Further, as Figure 6-Figure 7 and Figure 10-Figure 12 shown, the rope dipping assembly 23 includes an oil storage tank 231 provided on the frame 31 and filled with lubricating oil, a filter box 232 provided on the outer wall of the oil storage tank 231, a pump body 233 provided on the outer wall of the oil storage tank 231 and used to suck the lubricating oil in the oil storage tank 231 into the filter box 232 for filtering, a scrubbing unit 234 provided inside the oil storage tank 231 and used to scrub the cotton rope 21, and a transmission unit 235 provided inside the oil storage tank 231 and used to drive the scrubbing unit 234 to work; The scrubbing unit 234 includes: A hollow plate 2341, which is divided into two groups and horizontally slidably arranged on the two inner side walls of the oil storage tank 231. A first chute 2342 is opened on the inner side wall of the oil storage tank 231. The hollow plate 2341 is slidably arranged on the first chute 2342 through a first slider. A second elastic member is arranged between the first slider and the two ends of the first chute 2342; An extension plate 2343, which is slidably arranged inside the hollow plate 2341. A third elastic member 2344 is arranged between the extension plate 2343 and the hollow plate 2341; A scrubbing plate 2345, which is arranged on the extension plate 2343. Two groups of outwardly expanding arc plates 2346 are arranged on the scrubbing plate 2345; It is worth mentioning that the function of the outwardly expanding arc plate 2346 is to facilitate the lifting and shuttling of the pendant 241 between the two scrubbing plates 2345; The transmission unit 235 includes: A lifting plate 2351, which is slidably arranged on the inner side wall of the oil storage tank 231. A second chute 2352 is vertically opened on the inner side wall of the oil storage tank 231. The lifting plate 2351 is slidably arranged on the second chute 2352 through a second slider. A fourth elastic member is arranged between the second slider and the end of the second chute 2352; The drive belt 2353 is divided into two groups and symmetrically arranged on the inner side wall of the oil storage tank 231. The lifting plate 2351 is connected to the two drive belts 2353 respectively through connecting rods 2354. The drive belt 2353 is installed on the inner side wall of the oil storage tank 231 through a drive wheel. The drive plate 2355, several groups of the drive plates 2355 are respectively slidably arranged on the drive belt 2353 through bases 2356. A third chute is provided on the base 2356. The drive plate 2355 is slidably arranged on the third chute through a third slider. A fifth elastic member is arranged between the third slider and the end of the third chute. The second limiting track 2357 is divided into two groups and symmetrically arranged on the inner side wall of the oil storage tank 231. The second limiting track 2357 is respectively located on one side of the hollow plate 2341 and is used to drive the drive plate 2355 to drive the hollow plate 2341 to move.

[0053] It should be noted that the lubricating oil in the oil storage tank 231 is purified by the filter box 232.

[0054] It is worth mentioning that the drive plates 2355 on the two drive belts 2353 are arranged in a staggered manner, that is, the drive plates 2355 on the two drive belts 2353 drive the two hollow plates 2341 to move alternately, that is, the two hollow plates 2341 have a relative displacement, ensuring that the two scrubbing plates 2345 achieve the scrubbing effect.

[0055] In this embodiment, through the cooperation of the rope dipping assembly 23 and the falling component 24, on the one hand, the cotton rope 21 can be smoothly pulled down into the oil storage tank 231, facilitating the replenishment of lubricating oil on the cotton rope 21, preventing the lubricating oil on the cotton rope 21 from drying up, and ensuring that the cotton rope 21 can continue to work; on the other hand, the cotton rope 21 can be automatically scrubbed to clean the dust and foreign matters on the cotton rope 21, preventing excessive accumulation of foreign matters on the cotton rope 21, ensuring the cleanliness of the cotton rope 21 itself, and improving the cleaning ability of the cotton rope 21.

[0056] Specifically, during the period when the pipe stays, the third driving member 224 drives two hollow blocks 223 to approach each other through the bidirectional lead screw 222, so that the cotton rope 21 loosens the pipe. At the same time, the dropping component 24 drives the pendant 241 to drive the cotton rope 21 to descend into the oil storage tank 231 for refueling. When the pendant 241 descends and shuttles through the gap between the two scrubbing plates 2345, the two scrubbing plates 2345 elastically clamp the descending cotton rope 21. The pendant 241 descends to the surface of the lifting plate 2351, and the pendant 241 drives the lifting plate 2351 to continue descending, so that the lifting plate 2351 drives two transmission belts 2353 to rotate synchronously through the connecting rod 2354, so that the transmission plates 2355 on the transmission belts 2353 move upward in sequence to the position of the second limiting track 2357. The second limiting track 2357 drives the transmission plate 2355 to drive two hollow plates 2341 to move alternately, so that the hollow plates 2341 drive the two scrubbing plates 2345 to scrub the descending cotton rope 21, cleaning the dust and foreign matters on the cotton rope 21. The pump body 233 sucks the lubricating oil in the oil storage tank 231 into the filter box 232 for purification to ensure that the lubricating oil in the oil storage tank 231 is clean. Similarly, the third driving member 224 drives the two hollow blocks 223 to move away from each other through the bidirectional lead screw 222, and drives the cotton rope 21 to rise. The lifting plate 2351 loses the pressure of the pendant 241 and rises and resets under the elastic force of the fourth elastic member. The transmission belt 2353 rotates reversely and resets, so that the transmission plates 2355 on the transmission belt 2353 drive the two scrubbing plates 2345 to scrub the rising cotton rope 21 again until the transmission belt 2353 resets, waiting for the next use.

[0057] Further, as Figure 10-Figure 12 shown, the dropping component 24 includes: A pendant 241, which is arranged at the bottom of the cotton rope 21. A steel rope 242 is arranged at the lower end of the pendant 241. The lower end of the steel rope 242 penetrates through the lifting plate 2351. Both the upper and lower ends of the pendant 241 are conical structures and are used to drive the lifting plate 2351 to descend; A reel 243, which is arranged on the inner side wall of the oil storage tank 231 and is used to reel the steel rope 242. A fourth driving member 244 for driving the reel 243 is arranged on the outer wall of the oil storage tank 231.

[0058] It should be noted that the fourth driving member 244 adopts an existing stepper motor.

[0059] It is worth mentioning that both the upper and lower ends of the pendant 241 are conical structures, which is convenient for the pendant 241 to lift and shuttle between the two scrubbing plates 2345.

[0060] In this embodiment, through the cooperation of the falling component 24 and the rope tightening component 22, not only can the cotton rope 21 be pulled down into the oil storage tank 231 to replenish lubricating oil, but also power is provided for the scrubbing unit 234 to work. Specifically, during the time period when the pipe stays, the third driving member 224 drives the two hollow blocks 223 to approach each other through the bidirectional lead screw 222, so that the cotton rope 21 loosens the pipe. At the same time, the fourth driving member 244 drives the winding wheel 243 to wind up the steel rope 242, so that the steel rope 242 drives the cotton rope 21 to descend into the oil storage tank 231 through the pendant 241 to replenish lubricating oil. Similarly, the third driving member 224 drives the two hollow blocks 223 to move away from each other through the bidirectional lead screw 222, and drives the cotton rope 21 to rise, and the fourth driving member 244 drives the winding wheel 243 to release the steel rope 242.

[0061] Embodiment Three As Figure 3-Figure 4 and Figure 13-Figure 15 shown, where the same or corresponding components as in Embodiment One are provided with the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The difference between this Embodiment Two and Embodiment One lies in: As Figure 13-Figure 15 shown, the cleaning mechanism 4 is divided into two groups and is respectively used to clean the rolling grooves of the two rolling rolls 323. It includes a scraping component 41 arranged on the calendering frame 321 and a collecting unit 42 arranged on the scraping component 41; The scraping component 41 includes: A cross beam 411, and the cross beam 411 is arranged inside the calendering frame 321; A U-shaped scraping plate 412, the U-shaped scraping plate 412 horizontally penetrates and is slidably arranged on the cross beam 411, the arc-shaped head of the U-shaped scraping plate 412 can change its diameter, the arc-shaped head of the U-shaped scraping plate 412 abuts in the rolling groove of the rolling roll 323 and adapts to the change in the diameter of the rolling groove, a sixth elastic member 413 is arranged between the two legs of the U-shaped scraping plate 412, and seventh elastic members 414 are arranged between the two legs of the U-shaped scraping plate 412 and the cross beam 411; A load-bearing plate 415, the load-bearing plate 415 is arranged on the cross beam 411, downward extension rods 416 are arranged on both legs of the U-shaped scraping plate 412, two groups of third limiting tracks 417 are symmetrically arranged on the load-bearing plate 415, and the third limiting tracks 417 drive the downward extension rods 416 to drive the two legs of the U-shaped scraping plate 412 to approach each other; It should be noted that the third limiting track 417 on the load-bearing plate 415 is in contact with the bottom of the U-shaped scraping plate 412, so that the third limiting track 417 plays a role in upwardly supporting the U-shaped scraping plate 412 to prevent the U-shaped scraping plate 412 from bending; The collecting unit 42 includes: A collecting hood 421 is provided on the arc-shaped head of the U-shaped shovel plate 412. A number of groups of spacer plates 422 are provided on the collecting hood 421 to prevent the foreign objects removed from falling out of the collecting hood 421. The collecting hood 421 is made of a flexible material and can be deformed, and can bend synchronously with the arc-shaped head of the U-shaped shovel plate 412; A collecting box 423 is provided on the cross beam 411 and is connected to the collecting hood 421 through a hose. A negative pressure machine 424 is provided on the side of the collecting box 423.

[0062] It should be noted that the structure and function of the negative pressure machine 424 are both prior arts and will not be elaborated here.

[0063] In this embodiment, by the cooperation of the removing assembly 41 and the collecting unit 42, on the one hand, it can automatically and continuously clean two rolling grooves with different radius sizes on the rolling mill, adapt to the variable diameter of the rolling groove, remove the foreign objects inside the rolling groove, improve the cleanliness of the inside of the rolling groove of the rolling mill, and avoid the foreign objects inside the rolling groove from damaging the surface of the pipe; on the other hand, it can timely collect the removed dust and foreign objects, avoid the scattering of the dust and foreign objects, and improve the environmental hygiene degree of the equipment.

[0064] Specifically, during the process of two rolling mills rolling the pipe, the arc-shaped head of the U-shaped shovel plate 412 is always horizontally abutted in the rolling groove of the rolling mill. When a rolling groove with a smaller radius of the rolling mill passes through the position of the U-shaped shovel plate 412, due to the decrease in the radius of the rolling groove, it forces the U-shaped shovel plate 412 to move horizontally away from the rolling mill, so that the third limit track 417 drives the lower extension rod 416 to bring the two feet of the U-shaped shovel plate 412 closer to each other, thereby reducing the radius of the arc-shaped head of the U-shaped shovel plate 412 to adapt to the inner wall of a rolling groove with a smaller radius, that is, the arc-shaped head of the U-shaped shovel plate 412 abuts against the inner wall of a rolling groove with a smaller radius. Similarly, when a rolling groove with a larger radius of the rolling mill passes through the position of the U-shaped shovel plate 412, the U-shaped shovel plate 412 moves horizontally towards the rolling mill to reset, and the two feet of the U-shaped shovel plate 412 move away from each other to reset, so as to adjust the radius of the arc-shaped head of the U-shaped shovel plate 412 to re-adapt to the inner wall of a rolling groove with a larger radius, and cycle in turn, thereby removing the foreign objects on the inner wall of the rolling groove of the rolling mill. The negative pressure machine 424 sucks the foreign objects removed in the collecting hood 421 into the collecting box 423 through the hose for unified treatment.
