Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a feeding mechanism for a cold rolling mill. Background Art

[0002] A cold rolling mill is a new type of steel bar cold rolling processing equipment. This machine can process hot-rolled wire rods and hot-rolled coils with a diameter between 6.5 mm and 12 mm into cold-rolled ribbed steel bars with a finished product specification diameter between 5 mm and 12 mm. The cold-rolled ribbed steel bars rolled by the cold rolling mill are a replacement product of cold-drawn low-carbon steel wires in prestressed concrete components. In cast-in-place concrete structures, they can replace grade I steel bars to save steel. They are a relatively good type among similar cold-worked steel products. The cold rolling mill processes coiled steel bars. After the processing of the coiled steel bars is completed, the next coil of steel bars needs to be sent to the processing position again.

[0003] In the utility model with the publication number CN221063914U, an automatic and efficient feeding device for a cold rolling mill is disclosed, including a feeding platform and coiled steel bars. A set of feeding racks are fixedly installed on the top side of the feeding platform. A placing component is arranged on the feeding racks. A stock preparation platform is installed above the feeding platform. A moving slot is opened on one side of the stock preparation platform. A winding shaft is placed on the moving slot. The coiled steel bars are wound around the winding shaft. For this automatic and efficient feeding device for a cold rolling mill, when the coiled steel bars on the feeding racks are used up, the telescopic cylinder on the telescopic component is started to operate. By pushing, the winding shaft will be pushed to the slow feeding component on one side. The conveying and stretching belt on the slow feeding component can catch the winding shaft. Under the gravity of the winding shaft, the conveying and stretching belt moves downward and finally falls on the rotating shaft placing groove, realizing automatic and efficient feeding. By using this equipment, the feeding time can be greatly reduced, and more time can be gained for processing.

[0004] However, when the coiled steel bars fall from the moving slot onto the stretching belt, due to the gravity of the coiled steel bars, the stretching belt instantaneously changes from a relaxed state to a taut state, and the impact of the coiled steel bars on the stretching belt is relatively large, affecting the service life of the slow feeding component. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that in the existing feeding mechanism for a cold rolling mill, the slow feeding component is greatly impacted by the coiled steel bars during use, affecting its service life, and to propose a feeding mechanism for a cold rolling mill.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A cold rolling mill feeding mechanism includes two groups of steel bar support seats and a slow blanking component installed on a base. A slow-down groove is provided on the end faces of the two steel bar support seats that are close to each other. The slow-down groove includes a stretching belt corresponding to the slow-down groove. The slow-down groove is connected to the steel reel groove. The bottom of the slow-down groove is a slope structure that gradually decreases towards one end of the steel reel groove. A brake component for adjusting the rolling speed of the steel bar coil is provided on the steel bar support seat.

[0008] Furthermore, the brake assembly includes a blocking block that rotates along the rolling direction of the steel bar coil, and the blocking block is connected to the working end of the driving source.

[0009] Furthermore, the stretching belt is laid along the rolling direction of the steel bar coil, one end of the stretching belt is connected to the stretching belt winding drum, and the other end is connected to the pin shaft.

[0010] Furthermore, the middle of the stretching belt passes around the rotating drum, the rotating drum is located above the stretching belt groove and close to the higher end of the slow-down groove, and the stretching belt passes around the side of the rotating drum away from the steel reel groove.

[0011] Furthermore, the stretching belt is located directly above the slow-descent trough, and a stretching belt groove for accommodating the stretching belt is provided at the bottom of the slow-descent trough.

[0012] Furthermore, the stretching belt groove extends to the bottom of the steel reel groove.

[0013] Furthermore, the distance between the pin shaft and the rotation center of the driving source is smaller than the rotation radius of the driving source.

[0014] Compared with the prior art, the present invention provides a cold rolling mill feeding mechanism with the following beneficial effects:

[0015] The utility model discloses a feeding mechanism for a cold rolling mill. When in use, a steel bar coil is set between two slow-drop grooves, a brake component is used to block the steel bar coil, so that the steel bar coil rotates slowly and rolls slowly from a high end to a low end of the slow-drop groove, and is slowly pressed on a slow blanking component at the same time.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Referring to Figures 1-6 , a feeding mechanism of a cold rolling mill of the present utility model includes two groups of steel bar support seats 2 and a slow blanking assembly 3 installed on the base 1. On the end faces of the two steel bar support seats 2 close to each other, slow-down grooves 201 are provided. The slow-down grooves 201 are of a stepped structure, with the top and inner sides of the slow-down grooves 201 open. During use, the steel bar coil 5 is placed between the two slow-down grooves 201.

[0027] The slow blanking assembly 3 includes a stretching belt 302 corresponding to the slow-down groove 201. The stretching belt 302 corresponding to the slow-down groove 201 means that when the steel bar coil 5 rolls on the slow-down groove 201, the stretching belt 302 can catch the steel bar coil 5.

[0028] The slow-down groove 201 is communicated with the steel reel groove 203. The steel reel groove 203 is a U-shaped groove with an open top, so that the steel bar coil 5 can directly roll from the slow-down groove 201 into the steel reel groove 203. When the steel bar coil 5 is in the steel reel groove 203, the steel bars on the steel bar coil 5 enter the cold rolling mill.

[0029] The bottom of the descending trough 201 is a slope structure that gradually decreases towards one end of the steel reel trough 203. A brake component 4 for adjusting the rolling speed of the steel reel coil 5 is installed on the steel bar support seat 2. When the steel reel coil 5 rolls from the high end to the low end of the descending trough 201, the brake component 4 is used to slow down the rolling speed of the steel reel coil 5, so that the steel reel coil 5 slowly rolls onto the stretching belt 302. During the slow contact process with the steel reel coil 5, the stretching belt 302 gradually tightens and straightens until the belt 302 is pulled in to fully bear the gravity of the steel reel coil 5, and then the steel reel coil is slowly placed into the steel reel trough 203.

[0030] The brake assembly 4 includes a blocking block 402 that rotates along the rolling direction of the steel bar coil 5. The blocking block 402 is connected to the working end of the driving source 401. The driving source 401 can be an electric motor. A reduction gear set can be selected between the blocking block 402 and the driving source 401 for transmission connection. The steel bar coil 5 includes a steel reel 502 and a rolled steel bar 501 wound on the steel reel 502. When the steel bar coil 5 is placed in the slow-down trough 201, the blocking block 402 is rotated so that the blocking block 402 blocks the steel reel 502 to prevent the steel reel 502 from rolling on the slow-down trough 201.

[0031] When the previous roll of steel bar coil 5 is used up, the driving source 401 is started to drive the blocking block 402 to rotate slowly in the direction of the steel reel groove 203. Under the action of gravity, the steel bar coil 5 automatically rolls toward the steel reel groove 203 on the slow-down groove 201. While rolling, it is blocked by the slow rotation of the blocking block 402, and the steel bar coil 5 also rolls slowly.

[0032] The stretching belt 302 is laid along the rolling direction of the steel bar coil 5. One end of the stretching belt 302 is connected to the stretching belt winding drum 301, and the other end is connected to the pin shaft 304. The pin shaft 304 is fixed on the steel bar support seat 2. The stretching belt winding drum 301 is driven by the second motor. When the steel bar coil 5 is slowly pressed on the stretching belt 302 under the deceleration effect of the brake assembly 4, the stretching belt winding drum 301 slowly lengthens the stretching belt 302, so that the steel bar coil 5 slowly falls into the steel reel groove 203.

[0033] The middle of the stretching belt 302 passes around the drum 303, which is located above the stretching belt slot 202 and close to the higher end of the slow-down slot 201. The stretching belt 302 passes around the side of the drum 303 away from the steel reel slot 203. Figures 3-4 As shown, when the steel bar coil 5 rolls toward the side of the steel reel groove 203, the stretching belt reel 301, the rotating drum 303, the pin shaft 304 and the stretching belt 302 form a simple fixed pulley system, which is equivalent to a simple labor-saving lever structure, further reducing the gravity impact of the steel bar coil 5 on the slow blanking component 3 as a whole.

[0034] The stretching belt 302 is located directly above the descending groove 201. A stretching belt groove 202 for accommodating the stretching belt 302 is machined at the bottom of the descending groove 201, which can reduce the space occupied by the device. At the same time, when the steel bar coil 5 compresses the stretching belt 302 to make the stretching belt 302 taut, the stretching belt groove 202 prevents the steel bar coil 5 from pressing the stretching belt 302 between the steel reel 502 and the descending groove 201.

[0035] The stretching belt groove 202 extends to the bottom of the steel reel groove 203. When the steel bar coil 5 is in use, the stretching belt 302 is accommodated in the stretching belt groove 202 within the steel reel groove 203.

[0036] The distance between the pin shaft 304 and the rotation center of the blocking block 402 is less than the rotation radius of the blocking block 402. Specifically, as Figure 4 , when the steel reel 502 is installed in the descending groove 201, the blocking block 402 is located between the pin shaft 304 and the steel reel 502. The blocking block 402 is rotatably installed on the steel bar support base 2 through a rotating shaft, and the height of the rotating shaft is lower than that of the pin shaft 304. When the blocking block 402 rotates to Figure 4 the position overlapping with the pin shaft 304 in , the blocking block 402 still has a blocking and decelerating effect on the steel bar coil 5. At the same time, the steel bar coil 5 has begun to slowly compress the stretching belt 302, thereby avoiding the stretching belt 302 from being impacted by the steel bar coil 5.

[0037] Working principle: During use, the steel bar coil 5 is hoisted and installed in the descending groove 201, and the blocking block 402 is rotated to block the steel bar coil 5 to prevent the steel bar coil 5 from rolling downwards.

[0038] When the previous steel bar coil 5 is used up, the steel reel 502 used by the previous steel bar coil 5 is taken out from the steel reel groove 203, and then the stretching belt winding disc 301 is started to tighten. The stretching belt 302 is tightened to the position as shown in Figure 4 . Then, the driving source 401 is used to drive the blocking block 402 to slowly rotate, so that the steel bar coil 5 slowly rolls downwards. The steel bar coil 5 slowly contacts the stretching belt 302 to make the stretching belt 302 taut. After the steel bar coil 5 is separated from the blocking block 402, the stretching belt winding disc 301 slowly releases the stretching belt 302, so that the steel bar coil 5 continues to slowly fall until the steel bar coil 5 falls into the steel reel groove 203 and the feeding is completed.
