Description

Technical Field

[0001] The present invention relates to the technical field of steel bar processing, and in particular to a flexible steel bar processing production line. Background Art

[0002] Rebar processing usually includes three processes: cutting, thread rolling and bending. Since the length of the rebar is long and the processing requirements are different, each processing process currently has a large area of ​​equipment for processing. However, a single machine can only complete a single process, and a crane is required when each device is transported. Not only is the installation cost high, but the transportation is time-consuming and difficult to accurately locate. Even when arriving at the processing location, manual assistance is still required to enter the processing position. Moreover, when the workshop is busy, it is impossible to set up multiple cranes at the same time. Therefore, if a crane is used in one process, other processes can only wait, and the problem of low efficiency cannot be solved.

[0003] The existing processing method mixes steel bar types and grades, and steel bars of different diameters are piled together, making it difficult to distinguish. In the use of steel bars, there is a common situation of preferring long steel bars to short steel bars and discarding them at will. Only whole steel bars are used on site, and short steel bars are often treated as waste, resulting in excessive steel bar loss.

[0004] When existing steel bar equipment processes steel bars of different diameters and processes positive and negative steel bar wires, it is necessary to manually adjust the rib stripping knife and manually replace the thread rolling die and bending die. The order processing requires different lengths and diameters, and the batch size is small, which leads to frequent and long replacement time and low processing efficiency. Summary of the invention

It should be noted that there is only one lifting and transfer module, which is a transportation hub, and can ensure that different working conditions are carried out in an orderly manner.

[0089] This embodiment provides a flexible processing production line that integrates steel bar raw material storage, picking, sawing, rib stripping, thread rolling, bending, and finished product stacking. The PLC controls the logical actions of each process to realize unmanned processing. The processing from raw materials to finished products is fully automatic, and there is no need to manually switch molds, which reduces manual assistance time; the workpiece does not fall to the ground during the processing, and continuous assembly line production is carried out to reduce logistics lifting. The main processing modules adopt a modular design to achieve overall quick disassembly and assembly, and the external dimensions are adapted to freight needs. The production line can be transferred with the construction site to realize nomadic production and reduce the transportation cost of steel bars.

[0090] In a preferred embodiment of the present invention, a production process of a flexible steel bar processing production line is provided. Figure 2 The precise picking module includes a cutting plan unit. The process of obtaining the cutting plan (length and number of pieces) is as follows: Different construction project departments, based on the engineering construction drawings, use lofting software to loft the construction drawings to form a shaped steel bar batching list and import it into the intelligent steel bar processing management system; the algorithm software conducts a comprehensive nesting design for steel bar cutting of the processing data, that is, the shaped steel bar batching list, to form a cutting plan (length and number of pieces), minimizing the loss rate to the greatest extent.

[0091] See Figure 3 In a preferred embodiment of the present invention, the precise picking module can precisely pick single steel bars of different specifications or efficiently process batches of steel bars of the same specification. When picking, different specifications of steel bars can be switched arbitrarily, and steel bars of different specifications can be picked according to a pre-set program and conveyed into the fixed-length sawing module through the picking and discharging conveyor line 206. Its specific structure mainly includes a moving raw material bin 101, a driving component 102, a guide rail 103, and a picking component 104. The raw material bin 101 can move and includes multiple storage positions for storing steel bar raw materials of different diameters. Generally, the whole bundle of steel bar raw materials is loaded and placed into the respective storage positions of the moving raw material bin according to the diameter; the guide rail 103 is installed at the bottom of the raw material bin 101; the driving component 102 drives the raw material bin to move along the guide rail; the picking component 104 combines a mechanical flattening and sorting mechanism and visual recognition to achieve precise grasping and rolling of single steel bars.

[0092] The precise picking module in this embodiment precisely grasps steel bars of a specified specification, laying a foundation for obtaining the steel bars of specified components subsequently.

[0093] In a preferred embodiment of the present invention, the steel bars sent out by the precise picking module enter the cutting process. Specifically, the fixed-length sawing module 2 cuts the steel bars to the specified length according to the batching list and algorithm settings. The fixed-length cutting module is composed of multiple saws (three electric saws in this case) working联动, respectively cutting the head end of the steel bar flat, cutting the middle part to a fixed length, and cutting the tail end of the remaining material or waste material. The multi-saw联动 sawing is realized through the annular conveyor line to improve efficiency; the servo-controlled fixed-length blocking mechanism is used to precisely control the cutting length of the steel bars. It is worth mentioning that, see Figure 8 The annular conveyor line is composed of conveyor line one 204, conveyor line two 201, conveyor line three 211, and conveyor line four 204. The steel bars have two flow directions on the four conveyor lines. One flow direction is in the shape of "匚", and the other flow direction is in the shape of "▏". The two flow directions are combined together to be similar to a ring, so it is called an annular conveyor line.

[0094] For the structure of the fixed-length sawing module 2, see Figure 4Specifically: the pick-up material conveyor line 206 is used to place the steel bars output by the precise pick-up module 1; the conveyor line 1 204 is parallel to the pick-up material conveyor line; the conveyor line 2 201 is arranged on the extension line of the conveyor line 1 204; the conveyor line 3 211 is parallel to the conveyor line 2 201; the conveyor line 4 208 is arranged on the extension line of the conveyor line 3 211 and is parallel to the conveyor line 1 204; the lifting and flipping mechanism 205 is a chain transmission mechanism, which receives the steel bars of the pick-up material conveyor line 206 and then lifts and flips them to the conveyor line 1 204; the flipping mechanism 205 controls the flipping of the picking-up material conveying line 206, conveying line 1 204, conveying line 2 201 and conveying line 4 208; the electric saw 1 207 is arranged at the lifting flipping mechanism 205, and is used to saw the head of the steel bar; the electric saw 202 is arranged between the conveying line 1 204 and the conveying line 2 201; the electric saw 3 203 is arranged between the conveying line 3 211 and the conveying line 4 208; the fixed-length blocking mechanism 1 209 is arranged at the conveying line 2 201; the fixed-length blocking mechanism 2 210 is arranged at the conveying line 4 208. Generally, the fixed-length blocking mechanism 209 and the fixed-length blocking mechanism 2 210 are both composed of a movable baffle and a telescopic electric cylinder. Figure 4 A fixed beam is arranged above a fixed conveyor frame that supports the conveyor, and a guide rail is arranged on the lower surface of the fixed beam. A telescopic electric cylinder is fixed to the fixed beam, and the telescopic cylinder of the telescopic electric cylinder is connected to the baffle. The telescopic electric cylinder is started to drive the baffle to move along the guide rail (in the direction of steel bar conveying). A distance sensor is arranged side by side with the electric saw to measure the distance between the baffle and the electric saw on the conveyor line on the same side, and the distance is the length of the steel bar to be sawed.

[0095] Furthermore, in another preferred embodiment of the present invention, a process method for fixed-length sawing is provided, which can be seen in Figure 8 , the specific workflow is as follows:

[0096] Step 1: The picked-up single steel bar is sent from the picking-up material conveyor line 206 to the direction of the electric saw 207. After being transported to the right place, the steel bar is flipped into the material trough of the lifting and flipping mechanism 205 and the end is pushed and positioned. The electric saw 207 presses down to saw the head of the steel bar. After the sawing is completed, the lifting and flipping mechanism 205 sends the steel bar to the conveyor line 204.

[0097] Step 2: The fixed-length blocking mechanism 209 is moved to the set position so that the distance between its baffle and the electric saw 202 is the sawing length. The conveyor line 204 is started to send the steel bar to the fixed-length blocking mechanism 210. When the end of the steel bar reaches the baffle, the electric saw 202 is pressed down for sawing.

[0098] Step 3: The steel bars on conveyor line 1 204 are flipped to conveyor line 4 208 , and at the same time, the steel bars on conveyor line 2 201 are flipped to conveyor line 3 211 .

[0099] Step 4: The steel bars of conveyor line 4 208 are flipped to the later process, and conveyor line 1 204 receives the steel bars of the second cycle.

[0100] Step 5: Fixed-length blocking mechanism 1 209 and fixed-length blocking mechanism 2 210 are moved to the set position, and the steel bars of conveyor line 3 211 and conveyor line 1 204 are conveyed toward the baffle. After reaching the position, electric saw 2 202 and electric saw 3 203 cut the steel bars.

[0101] Step 6: The steel bars on conveyor line four 208 are flipped to the post-process, and then the steel bars on conveyor line three 211 are sent to conveyor line four.

[0102] Step 7: The steel bars on conveyor line four 208 are flipped to the later process. At this time, the first steel bar completes the fixed-length sawing action, and then the steel bars on conveyor line one 204 are flipped to conveyor line four 208. At the same time, the steel bars on conveyor line two 201 are flipped to conveyor line three 211.

[0103] Repeat steps 4 to 7 to achieve circular feeding and multiple saw linkage fixed-length sawing.

[0104] The cyclic feeding and multi-saw linkage in the above embodiment effectively improves the efficiency of steel bar sawing.

[0105] In a preferred embodiment of the present invention, the rib stripping and thread rolling module 4 is mainly composed of two sets of automatic rib stripping mechanisms and two sets of automatic thread rolling mechanisms, which are respectively placed at both ends of the steel bars, and cooperate with the flap and conveyor line group to complete the automatic rib stripping and thread rolling processes at both ends of the steel bars.

[0106] The structure of the stripping and rolling module 4 can be seen in Figure 6 Specifically: the rib stripping and thread rolling conveyor line group 405 includes a left rib stripping conveyor line 40501 and a right rib stripping conveyor line 40502 that are parallel to each other; includes a left thread rolling conveyor line 40503 and a right thread rolling conveyor line 40504 that are parallel to each other;

[0107] The rib peeling machine unit includes a left rib peeling machine 409 located at one end of the left rib peeling conveyor line 40501 and a right rib peeling machine 401 located at the other end of the right rib peeling conveyor line 40502;

[0108] The thread rolling machine group includes a left thread rolling machine located at one end of the left thread rolling conveyor line 40503 and a right thread rolling machine 402 located at the other end of the right thread rolling conveyor line 40504; the flap is located at the ends of the rib stripping conveyor line group and the threading conveyor line group.

[0109] Further, in a preferred embodiment of the present invention, a rib stripping thread rolling process is provided, which can be seen in Fig.10 , as follows:

[0110] Step 1: The steel bars of the wire rolling feeding buffer mechanism 404 flow into the left rib stripping conveyor line 40501, and then the steel bars are moved toward the left rib stripping machine 409 for left end rib stripping.

[0111] Step 2: After the left rib stripping is completed, the steel bars on the left rib stripping conveyor line are flipped over to the right rib stripping conveyor line 40502, and then the steel bars are moved to the right rib stripping machine 410 for right-end rib stripping. At the same time, the next steel bar is connected to the left rib stripping conveyor line.

[0112] Step 3: After the rib stripping at both ends is completed, the steel bars of the right rib stripping conveyor line are flipped to the left wire rolling conveyor line 40503, and then the steel bars are rolled on the left end in the direction of the left wire rolling machine 410. At the same time, the first two conveyor lines are flipped and conveyed in sequence.

[0113] Step 4: After the left wire rolling is completed, the steel bars of the left wire rolling conveyor line are flipped to the right wire rolling conveyor line 40504, and then the steel bars are rolled on the right end in the direction of the right wire rolling machine 402. At the same time, the first three conveyor lines are flipped and conveyed in sequence. This completes the rib stripping and wire rolling process of the first steel bar.

[0114] The above steps can be repeated for subsequent steel bars. If only the left end of the steel bar needs to be stripped and threaded, only steps one and three are performed. On the contrary, if only the right end of the steel bar needs to be stripped and threaded, only steps two and four are performed.

[0115] Similarly, the above-mentioned rib stripping and thread rolling can allow multiple steel bars to enter the rib stripping and thread rolling process at the same time, effectively improving production efficiency.

[0116] In a preferred embodiment, the rib stripping mechanism is provided with an automatic adjustment and centering mechanism for the rib stripping knife, and the position and size of the rib stripping knife can be automatically adjusted according to the specifications of the steel bar to realize the rib stripping processing of steel bars of different sizes. After the rib stripping is completed, the automatic knife expansion mechanism opens the rib stripping knife to realize rapid knife withdrawal and chip removal. In the automatic adjustment mechanism for the position of the thread rolling wheel of the thread rolling mechanism, the size and position of the thread wheel can be automatically adjusted to realize the automatic thread rolling processing of steel bars of different specifications; the mechanism includes a variety of thread rolling wheels of various specifications, and can be compatible with the automatic switching of thread rolling wheels of various specifications; by automatically switching the position of the thread rolling wheel, the positive and negative thread rolling processing of the steel bar can be realized; after the steel bar thread rolling processing is completed, the thread rolling wheel can be quickly withdrawn to realize the function of rapid thread rolling withdrawal.

[0117] In a preferred embodiment of the present invention, a preferred structure of a lifting and transporting module is provided, and the lifting and transporting module is arranged at the rib stripping and thread rolling module. Figure 6 The lifting and transfer module includes a lifting and transfer mechanism 1 403 , a thread rolling feeding buffer mechanism 404 , a transverse transfer mechanism 406 , a lifting and transfer mechanism 2 407 , and a discharge buffer mechanism 408 .

[0118] The thread rolling feed buffer mechanism 404 is used to temporarily store the steel bars that will enter the rib stripping thread rolling module 4 in the next process; the discharge buffer mechanism 408 is used to temporarily store the steel bars that will enter the finished product stacking module 5 in the next process.

[0119] The steel bars that have completed the fixed-length cutting process flow into the subsequent process according to the order requirements. Working condition 1: If thread rolling and bending are not required, they first descend through the lifting and transfer mechanism 403, then flow into the material discharging buffer mechanism 408, then flow into the material receiving conveyor line 506, and finally flow into the corresponding position of the finished product bin 502; Working condition 2: If thread rolling is required, they first rise to the middle position through the lifting and transfer mechanism 403, then flow into the thread rolling feed buffer mechanism 404, and finally enter the thread rolling conveyor line group 405; Working condition 3: If bending is required, they first rise to the high position through the lifting and transfer mechanism 403, then flow into the transverse movement conveyor mechanism 406, and finally flow into the bending feed buffer mechanism 302.

[0120] The steel bars that have completed the thread rolling process flow into the subsequent process according to the order requirements. Working condition 1: If bending is not required, the steel bars are lowered through the lifting and transfer mechanism 2 407, then flow into the material discharging buffer mechanism 408, then flow into the material receiving conveyor line 506, and finally flow into the corresponding position of the finished product bin 502; Working condition 2: If bending is required, the steel bars are first raised to a high position through the lifting and transfer mechanism 2 407, then flow into the transverse transfer mechanism 406, and finally flow into the bending feed buffer mechanism 302.

[0121] The lifting and transfer module of the above embodiment is concentrated at the rib stripping and thread rolling module through a clever and compact design, but has no substantial connection with it, and does not affect the progress of subsequent module disassembly and reassembly. Through the lifting and transfer module, different working conditions are operated in an orderly manner, ensuring that the workpiece does not fall to the ground during the processing process, and continuous assembly line production is carried out without logistics lifting.

[0122] In a preferred embodiment of the present invention, a preferred structure of the bending module 3 is provided, see Figure 5 , mainly composed of a left bending machine 303, an intermediate clamping machine 304, a right bending machine 305, a die changing mechanism 306, a lower support mechanism 307 and a guide rail beam mechanism 308. The left bending machine 303, the intermediate clamping machine 304 and the right bending machine 305 move in coordination with each other on the guide rail beam mechanism 308 to realize the automatic bending of steel bars of different lengths. The lower support mechanism 307 is located on the side of the entire bending module 3. There are multiple sets of bending movable molds 30301 in the two bending machines, and they can be automatically switched according to the different diameters of the steel bars; the bending fixed mold 30302 can be lifted out of the working surface twice, and cooperate with the die changing mechanism to realize automatic switching of the fixed mold. When the length of the bottom edge of the steel bar is less than the distance between the two bending fixed molds, the steel bar is clamped and transported axially through the clamping wheel group 30401 of the intermediate clamping machine to realize the automatic bending function of the short bottom plate steel bars, such as Fig. 9The steel bars that have completed the bending process enter the lower support mechanism 307 and then flow into the corresponding bin of the finished product bin according to the order requirements.

[0123] Further, in a preferred embodiment of the present invention, a short bottom steel bar bending process is provided, see Fig. 9 The conventional bending process is limited by the width of the two bending components and the intermediate auxiliary mechanism. The length L1 of the bottom side of the bent steel bar is relatively large, which results in that some specifications with shorter bottom sides cannot be automatically produced or require manual auxiliary production. The solution in this embodiment is: first complete the bending action at one end, and then lower the movable mold and fixed mold at that end ( Fig. 9 -A state), and then a movable mold and guide shaft 30304 at the other end are extended to guide the steel bar, and the steel bar is sent to another bending component through the pinch wheel. Fig. 9 -B state, and then complete the remaining bending actions Fig. 9 -C state, thereby shortening the bottom edge length to L2, reducing the radius of a bending component compared to L1.

[0124] Automatic replacement process of bending fixed mold: The mold changing mechanism 306 can store bending fixed molds of various specifications. In this case, there are three (fixed mold 1#30602; fixed mold 2#30603; fixed mold 3#30604). When producing steel bars of different diameters, the bending fixed mold 30302 on the bending machine needs to be switched; the automatic replacement method is as follows: the bending machine moves to the bottom of the mold changing mechanism, and the bending fixed mold is ejected to the high position by the fixed mold lifting cylinder. Then, the telescopic cylinder 30605 of the mold changing assembly extends, and the mold extends along the contour curve of the end plate 30601. Then the fixed mold lifting cylinder descends to take out the original bending fixed mold (in actual work, two molds are stored on the mold changing mechanism, and there is an empty space for the mold in use). The bending machine moves again to the bottom of the required fixed mold on the mold changing assembly, the mold lifting cylinder extends, and the mold changing mechanism cylinder retracts, and the required new fixed mold is placed on the bending machine to complete the mold changing action.

After the finished product silo 502 collects the steel bars of this batch, it is moved to the unloading position by the winch for manual bundling and labeling unloading; at the same time, another empty finished product silo is moved by the truss and placed on the moving trolley to realize the interaction of the two finished product silos.
