Description

Technical Field

[0001] The present invention relates to wire drawing forming equipment, and in particular to a mold-free segmented wire drawing forming equipment for steel fibers applied in the field of metal wire drawing forming. Background Technology

[0002] Steel fiber, a slender, high-strength filamentous material made from steel, is primarily produced using wire drawing equipment. This equipment consists of a feeding system, a main traction system, and a take-up mechanism. It applies axial tension to the steel wire at room temperature, causing it to pass through a die to achieve cross-sectional reduction and length extension, ultimately producing a steel fiber product that meets the required specifications. However, in existing technologies, the dies in wire drawing equipment gradually wear down with continuous use, leading to a significant decrease in subsequent processing accuracy.

[0003] To address the aforementioned issues, Chinese invention patent CN113634610B discloses a wire drawing machine for steel wire production. Through the coordinated operation of a size monitoring component and an adjustment component, it can monitor the dimensions of transition parts and products generated during processing in real time, and provide feedback on abnormal dimensions. It promptly adjusts the transverse and longitudinal wire drawing modules, ensuring that the dimensions of the processed products remain at a qualified level, avoiding resource waste and unnecessary rework due to untimely corrections and adjustments. Another Chinese invention patent, CN118321366B, discloses a wire drawing machine with easy material replacement. It can automatically replace worn molds after prolonged use without requiring extended downtime, thus improving the machine's efficiency.

[0004] Although existing technologies have optimized the operational efficiency of wire drawing equipment to some extent, in the multi-stage wire drawing process of steel fibers, progressive forming errors can occur between different processes due to factors such as differences in the wear of dies at each stage. As the processing progresses, these errors accumulate and can easily lead to problems such as steel fiber breakage, poor diameter consistency, and inadequate diameter reduction, severely affecting the product qualification rate. Such quality problems not only reduce the overall production efficiency of the equipment but also significantly increase production costs due to the rising proportion of defective products, ultimately weakening the economic benefits of steel fiber production. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to further improve the adaptability of wire drawing forming equipment, reduce the frequency of mold replacement and improve production efficiency.

[0012] As a further improvement of this application, the output end of the molding collaborative processing unit is also connected to a molding compensation control unit, and the output end of the molding compensation control unit is signal-connected to the mold control unit.

[0013] As a further improvement of this application, the transition mold includes a transition ring fixedly installed on the inner side of the right end of the mold support. Multiple transition sensing chambers are fixedly connected to the inner end of the transition ring, and the hydraulic system is connected to the transition sensing chambers through pipelines. A sensing arc block is fixedly connected to the inner end of the transition sensing chamber, and the input end of the transition sensing unit is connected to the transition pressure probe signal set in the transition sensing chamber.

[0014] As a further improvement of this application, the input end of the molding collaborative processing unit is also connected to a parameter command receiving unit, the input end of the parameter command receiving unit is connected to the control panel on the control cabinet, and the output end of the molding collaborative processing unit is also connected to a molding display unit and an abnormal display unit. The output end of the molding display unit is connected to the control panel on the control cabinet, and the output end of the abnormal display unit is connected to the alarm on the control cabinet.

[0015] As a further improvement of this application, a compensation lubrication cavity is fixedly connected to the inner end of the spacer arc block and disposed between two support blocks. Multiple lubrication blocks are fixedly connected to the inner end of the compensation lubrication cavity. Multiple compensation grooves that cooperate with the lubrication blocks are opened at the inner end of the formed arc block. Compensation columns are rotatably embedded in the compensation grooves.

[0018] In summary, through the cooperation of the forming mold, the transition mold, and the collaborative control unit, the transition mold can monitor and provide feedback on the steel fiber drawing state of the preceding forming mold in real time. This allows the collaborative control unit to intelligently adjust the drawing gap of the forming mold. At the same time, by integrating feedback information from multiple transition molds, precise collaborative control of the drawing speed is implemented. This not only effectively eliminates the cumulative errors of each production stage and significantly reduces quality fluctuations and defect rates, but also achieves dual optimization control of the drawing process and speed, thereby improving production efficiency, reducing cost losses, and enhancing production economy. In addition, through the connecting role of the transition mold, the diameter change amplitude between each stage can be effectively reduced, mitigating structural damage to the steel fiber during the drawing process, ensuring product quality stability, and ultimately improving the finished product qualification rate.

Detailed Implementation

[0030] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0031] Implementation method 1:

[0032] Figure 1 This invention illustrates a steel fiber segmented drawing and forming equipment that does not require mold changing. It includes a main body 1, a control cabinet 11 at the left end of the main body 1, multiple drawing and forming boxes 2 fixedly mounted on the upper end of the main body 1, guide pipes 21 fixedly connected to both ends of each drawing and forming box 2, a mold support 3 fixedly mounted on the lower inner wall of each drawing and forming box 2, and a forming mold 4 mounted on the left end of the mold support 3. The main body 1 is equipped with a main traction system that cooperates with the drawing and forming boxes 2, and a lubrication system that cooperates with the forming mold 4. Both the main traction system and the lubrication system utilize existing mechanical structures found in wire drawing and forming equipment; these are directly referenced here without any changes to their structure or principle, and therefore will not be elaborated upon.

[0033] The second implementation method:

[0034] Figure 1 - Figure 8 The diagram shows a segmented steel fiber drawing and forming equipment that does not require mold changing. It includes a main body 1, a control cabinet 11 located at the left end of the main body 1, and a forming coordination system installed inside the control cabinet 11. The forming coordination system includes a forming coordination processing unit. The input end of the forming coordination processing unit is connected to a transition sensing unit and a drawing data acquisition unit. The output end of the forming coordination processing unit is connected to a coordination control unit, a mold control unit, and a drawing speed control unit. The output end of the coordination control unit is connected to the mold control unit and the drawing speed control unit respectively. The command priority of the coordination control unit is higher than the command priority of the forming coordination processing unit.

[0035] Multiple wire drawing forming boxes 2 are fixedly installed on the upper part of the equipment body 1. Each wire drawing forming box 2 contains a forming mold 4 and a transition mold 5 located to the right of the forming mold 4. The input terminal of the transition sensing unit is connected to the signal of the transition mold 5. The input terminal of the wire drawing data acquisition unit is connected to the signal of the main traction system located on the equipment body 1. The output terminal of the mold control unit is connected to the signal of the hydraulic system located at the rear of the equipment body 1. The output terminal of the wire drawing speed control unit is connected to the signal of the main traction system located on the equipment body 1. Through the cooperation of the forming mold 4, the transition mold 5, and the collaborative control unit, the transition mold 5 can monitor and provide feedback to the preceding forming mold in real time. With four pairs of steel fiber drawing and forming states, the collaborative control unit can intelligently adjust the drawing gap of the forming mold 4. At the same time, by integrating feedback information from multiple transition molds 5, it can implement precise collaborative control of the drawing speed. This not only effectively eliminates the cumulative errors of each production stage and significantly reduces quality fluctuations and defect rates, but also achieves dual optimization control of the drawing and forming process and speed. This improves production efficiency, reduces cost losses, and enhances production economy. In addition, through the connecting effect of the transition molds 5, the diameter change amplitude between each stage can be effectively reduced, mitigating structural damage to the steel fibers during the drawing process, ensuring product quality stability, and ultimately improving the finished product qualification rate.

[0036] Figure 4 - Figure 8 The drawing forming box 2 is shown to have guide tubes 21 fixedly connected to both its left and right ends, and the two guide tubes 21 are respectively matched with the corresponding forming mold 4 and transition mold 5. A mold support 3 is fixedly installed on the lower inner wall of the drawing forming box 2. The forming mold 4 is installed on the left end of the mold support 3, and the transition mold 5 is installed on the right end of the mold support 3. Through the cooperation of the forming mold 4 and the transition mold 5, not only can the drawing forming state of the preceding steel fiber be monitored, but also the diameter reduction transition can be achieved by setting the transition mold 5, which further improves the diameter reduction quality and efficiency and ensures the quality of the drawing forming.

[0037] Figure 4 - Figure 8The forming mold 4 includes an outer mold ring 41 fixedly installed on the inner side of the left end of the mold support 3. Multiple adjustment chambers 42 are fixedly connected to the inner end of the outer mold ring 41. The number of adjustment chambers 42 is consistent with the number of transition sensing chambers 52, and the data volume of both adjustment chambers 42 and transition sensing chambers 52 is ≥4 sets. The hydraulic system is connected to the adjustment chambers 42 through pipelines. An interval arc block 43 is fixedly connected to the inner end of the adjustment chamber 42. A pair of support blocks are fixedly connected to the inner end of the interval arc block 43. A forming arc block 45 is fixedly connected between the two support blocks. The hydraulic system acts on the adjustment chamber 42 to realize the movement of the adjustment chamber 42, which drives the interval arc block 43 and the forming arc block 45 along its radial direction. In this way, the gap between multiple forming arc blocks 45 can be dynamically adjusted according to different wire drawing forming requirements. This not only effectively eliminates and compensates for errors at each stage and promotes the quality of steel fiber wire drawing forming, but also improves the applicability of the equipment body 1 and expands the application range of the equipment body 1.

[0038] Figure 1 - Figure 3 The input end of the forming collaborative processing unit is also connected to a forming state sensing unit. The input end of the forming state sensing unit is connected to the forming pressure probe located in the adjustment cavity 42. When multiple forming arc blocks 45 perform wire drawing forming on the steel fibers located therein, the gap between the multiple forming arc blocks 45 is smaller than the diameter of the steel fiber to be drawn. Thus, while achieving the diameter reduction effect on the steel fiber, the forming state sensing unit can also effectively monitor the wear state of the forming arc blocks 45 caused by continuous application based on the reaction force generated by the steel fiber on the forming arc blocks 45. The cooperation between the forming state sensing unit and the forming pressure probe can verify the dynamic diameter adjustment data, and then compensate for the dynamic diameter adjustment effect based on the verification data. This achieves precise control of the dynamic diameter adjustment effect of the forming mold 4, ensuring the applicability to steel fibers with different requirements. It can also monitor the wear state of the forming arc blocks 45 in real time, effectively promoting subsequent wear compensation and wear replacement, achieving the monitoring effect of the life of the forming arc blocks 45, and timely reminding technicians to replace them.

[0039] Figure 1 - Figure 3 The output of the forming collaborative processing unit is also connected to a forming compensation control unit. The output of the forming compensation control unit is connected to the mold control unit. The command priority of the forming compensation control unit is higher than that of the collaborative control unit. The setting of the forming compensation control unit can realize the compensation control function of the dynamic diameter adjustment of the forming mold 4. While eliminating the control error, it can also effectively compensate for the wear, reduce the frequency of mold changing and mold maintenance, suppress the generation of wire drawing forming errors at each stage, improve the wire drawing forming quality of steel fiber, and thus effectively improve the wire drawing forming quality and economy of steel fiber.

[0040] Figure 1 - Figure 8 The transition mold 5 includes a transition ring 51 fixedly installed on the inner side of the right end of the mold support 3. Multiple transition sensing chambers 52 are fixedly connected to the inner end of the transition ring 51, and the hydraulic system is connected to the transition sensing chambers 52 via pipelines. Sensing arc blocks 53 are fixedly connected to the inner end of each transition sensing chamber 52. The input end of the transition sensing unit is connected to a transition pressure probe located within the transition sensing chamber 52. In application, the transition sensing chamber 52 adjusts the gap between the multiple sensing arc blocks 53 to be smaller than the gap between the multiple forming arc blocks 45 in the preceding step. That is, the gap between the multiple sensing arc blocks 53 is within the lower limit range of the gap between the multiple forming arc blocks 45 in the preceding step. Therefore, after the steel fiber moves into the multiple sensing arc blocks 53, its own diameter will generate a certain expansion reaction force on the transition sensing chamber 52, allowing the transition sensing unit to determine the pressure change of the steel fiber within the transition sensing chamber 52. The diameter status is used to determine the wire drawing accuracy of the preceding forming mold 4. This not only plays an effective transition role but also enables data monitoring of the preceding steps, facilitating compensation of the preceding data and improving the quality of steel fiber wire drawing. The hydraulic system can regulate the transition induction chamber 52, causing the induction arc block 53 to move radially. This allows for corresponding transition diameter adjustment control when the forming mold 4 performs dynamic diameter adjustment, promoting the quality stability and efficiency of wire drawing. Furthermore, it monitors and provides feedback on the wire drawing quality of the preceding forming mold 4, promoting the coordinated control of the subsequent collaborative control unit on the wire drawing process and speed. This eliminates the accumulation of errors at each stage and enables high-precision control of the overall wire drawing process, achieving dual optimization control of the wire drawing process and speed.

[0041] It should be noted that the hydraulic system uses existing mechanical structures, which are directly referenced here without any changes to their structure and principle. Those skilled in the art can select them according to actual needs. For example, the hydraulic system includes a hydraulic tank, a hydraulic pump, hydraulic delivery pipelines, and electrically controlled valves installed on the pipelines. The mold control unit can control the hydraulic pump and the electrically controlled valves to regulate the input and output of hydraulic oil into the adjusting chamber 42 and the transition sensing chamber 52, respectively. This enables parallel control of the adjusting chamber 42 and the transition sensing chamber 52, thereby controlling their corresponding deformation, which in turn drives the corresponding forming arc block 45 and sensing arc block 53 to move. This is effectively applicable to the production of steel fibers with different wire drawing diameter requirements, which will not be elaborated here.

[0042] Figure 1 - Figure 3The input terminal of the forming collaborative processing unit is connected to a parameter command receiving unit. The input terminal of the parameter command receiving unit is connected to the control panel on the control cabinet 11. The output terminal of the forming collaborative processing unit is connected to a forming display unit and an abnormal display unit. The output terminal of the forming display unit is connected to the control panel on the control cabinet 11, and the output terminal of the abnormal display unit is connected to the alarm on the control cabinet 11. Technicians can input relevant parameters and commands for wire drawing forming into the parameter command receiving unit through the control panel. The parameters include the target diameter for wire drawing forming, the initial diameter for wire drawing forming, the step values ​​of each stage of wire drawing diameter, the dimensional accuracy range of wire drawing forming, the wire drawing speed, and the wire drawing tension, etc., which are related to the steel fiber drawing process parameters. The commands include start / stop commands, parameter compensation commands, and operation stop commands. The parameter command receiving unit converts these data and transmits them to the forming collaborative processing unit. The forming collaborative processing unit performs subsequent operation control based on the received data. During the process of controlling the steel fiber drawing process by the forming collaborative processing unit, the operating status of the equipment body 1 is also displayed to the technicians through the forming display unit and control panel. This allows production personnel to make timely compensation and adjustment of the drawing process parameters and perform relevant command control based on the actual operating data. While improving the automation and intelligence level of the equipment body 1, it can also effectively realize the interactivity and controllability of the forming collaborative system.

[0043] Figure 1 - Figure 8 The diagram shows that when the forming collaborative processing unit determines that the wire drawing forming parameters have changed based on the received data and the wire drawing diameter needs to be readjusted, the forming collaborative processing unit inputs the corresponding speed adjustment data into the wire drawing speed control unit based on the data to be adjusted in this batch and the data already adjusted in the previous batch. This enables the wire drawing speed control unit to control the main traction system so that it performs the wire drawing forming action according to the set parameter speed. At the same time, the corresponding diameter adjustment parameters are input into the mold control unit, so that the mold control unit hydraulically adjusts the adjustment cavity 42 and the transition sensing cavity 52 through the hydraulic system. This enables the adjustment cavity 42 to drive the interval arc block 43 and the forming arc block 45, so that a gap corresponding to the wire drawing forming diameter can be formed between multiple forming arc blocks 45. Furthermore, the transition sensing cavity 52 drives the sensing arc block 53 to move accordingly, so that the gap between multiple sensing arc blocks 53 can correspond to the wire drawing forming data on the previous forming mold 4.

[0044] During subsequent operation, the transition pressure probe in the transition sensing cavity 52 will transmit the pressure data it senses to the forming collaborative processing unit through the transition sensing unit, so that the forming collaborative processing unit can verify and judge the previous wire drawing forming diameter. When it is determined that the previous wire drawing forming diameter data meets the process parameter requirements, the control effect on the forming mold 4 and transition mold 5 in the multiple wire drawing forming boxes 2 is maintained at this time.

[0045] When the pre-drawing diameter data exceeds the process parameter requirements, the process diameter adjustment data, speed adjustment data, and out-of-range data are transmitted to the collaborative control unit. The collaborative control unit then coordinates the control of the die control unit and the drawing speed control unit based on the acquired data. In the event of localized drawing abnormalities, the die control unit is first used for unilateral control. When the die control unit reaches its limit or the control effect remains poor, the drawing speed control unit is then used for collaborative control. In the event of overall drawing abnormalities, the die control unit and the drawing speed are simultaneously controlled collaboratively to ensure the control effect and promote the guarantee of steel fiber drawing quality and efficiency.

[0046] During the continuous wire drawing process, the forming collaborative processing unit can, based on the previous wire drawing data transmitted by the transition sensing unit, combine with the collaborative control unit to achieve real-time dynamic control of the mold control unit and the wire drawing speed control unit, respectively. This effectively realizes the dual collaborative effect of dynamic diameter adjustment and dynamic speed adjustment. While promoting the versatility and applicability of the equipment body 1 to different wire drawing requirements, it can also effectively improve the production quality and efficiency of the equipment body 1, thereby promoting the economic efficiency of the application of the equipment body 1.

[0047] During the continuous operation of this batch of steel fiber drawing forming, the forming pressure probe in the adjustment cavity 42 continuously transmits the pressure data in the adjustment cavity 42 to the forming status sensing unit. The forming status sensing unit feeds back the status data to the forming collaborative processing unit. The forming control processing unit judges the wear status of the forming arc block 45 based on the received pressure change data. When it is determined that the forming arc block 45 has generated wear data and needs to be adjusted, the wear compensation data is transmitted to the forming compensation control unit. The forming compensation control unit transmits the compensation data to the mold control unit, so that the mold control unit controls the hydraulic system to increase the hydraulic pressure in the adjustment cavity 42, thereby achieving the compensation effect for the wear of the forming arc block 45 and ensuring the quality stability of subsequent wire drawing forming.

[0048] When the forming co-processing unit determines that the forming die 4 needs to be adjusted to meet the wire drawing forming requirements, the forming co-processing unit judges whether the control data meets the rated range of the forming die 4. If it meets the rated range, the aforementioned control action is performed. If it does not meet the rated range, the alarm is activated through the abnormal display unit, and the data is displayed to the technicians through the control panel via the forming display unit, prompting the technicians to check and modify the process parameters to meet the rated range of the forming die 4 and achieve the wire drawing forming effect of steel fibers. Furthermore, after the forming die 4 is worn down by continuous use, if the forming co-processing unit determines that its wear exceeds its lifespan, the alarm is activated through the abnormal display unit, and the data is displayed to the technicians through the control panel via the forming display unit, prompting the technicians to maintain and replace the forming die 4 to ensure the effectiveness of the continuous operation of the subsequent equipment body 1 and to avoid the safety risks caused by the continuous use of the forming die 4.

[0049] The third implementation method:

[0050] Figure 1 - Figure 9 This invention illustrates a segmented drawing and forming device for steel fibers that does not require mold changes. A compensating lubrication cavity 44, located between two support blocks, is fixedly connected to the inner end of an intermittent arc block 43. Multiple lubrication blocks are fixedly connected to the inner end of the compensating lubrication cavity 44. Multiple compensating grooves, which cooperate with the lubrication blocks, are opened at the inner end of the forming arc block 45. A compensating column 441 is rotatably embedded within the compensating groove. The inner end of the lubrication block extends into the compensating groove and slides in a sealed manner with it. The compensating column 441 facilitates the movement of the steel fibers passing through the forming arc block 45, effectively reducing the diameter of the drawn wire while also decreasing the friction between the steel fibers and the forming arc block 45, thus reducing wear on the forming arc block 45 and ensuring the quality of the drawn steel fibers.

[0051] Figure 1 - Figure 3 The lubrication block has a lubrication through hole that communicates with the compensating lubrication chamber 44. Conductive cotton is inserted into the lubrication through hole. The insertion method facilitates the replacement of the conductive cotton. The lubricant in the compensating lubrication chamber 44 permeates to the compensating groove through the conductive cotton and is coated on the surface of the steel fiber by the rotating compensating column 441, reducing friction loss. The output end of the forming co-processing unit is also connected to the lubrication compensation control unit. The output end of the lubrication compensation control unit is connected to the lubrication system signal set on the equipment body 1, and the lubrication system is connected to the compensating lubrication chamber 44 through the lubrication branch pipe. The setting of the lubrication compensation control unit can realize the lubrication effect of the steel fiber drawing forming process, play an effective role in heat dissipation and reducing friction loss, thereby reducing cold drawing damage when the steel fiber is drawn and reduced in diameter, ensuring the uniformity of its deformation, and promoting its forming quality.

[0052] Figure 1 - Figure 3 The illustration shows a further improvement to the functionality of this embodiment. This is an optional feature. Electromagnetic blocks are fixedly connected to both inner walls of the compensating lubrication cavity 44 perpendicular to its radial direction. The output end of the forming co-processing unit is also connected to a friction forming auxiliary unit. The output end of the friction forming auxiliary unit is signal-connected to the electromagnetic blocks. The setting of the friction forming auxiliary unit can control the rotational degree of freedom of the compensating column 441, thereby effectively promoting or inhibiting the movement of the steel fiber. It can be applied to different wire drawing requirements. When it is necessary to promote movement, the rotational degree of freedom of the compensating column 441 is released, effectively reducing friction and reducing the wear of the forming arc block 45. When it is necessary to inhibit movement, the rotational degree of freedom of the compensating column 441 is restricted, promoting the wire drawing forming action and playing a further compensating and regulating role in the wire drawing speed, ensuring the wire drawing forming quality of the steel fiber.

[0053] Figure 1 - Figure 9 As the steel fiber moves from the forming arc block 45, the rolling friction between it and the compensating column 441 causes the compensating column 441 to rotate within the compensating groove. This rotation of the compensating column 441 then transmits the lubricant that enters the compensating groove through the conductive cotton. This allows the lubricant to continuously act on the surface of the steel fiber, effectively reducing friction and cooling the surface. This effectively ensures the quality of the steel fiber drawing process. Furthermore, during continuous application, the forming co-processing unit can regulate the lubrication system according to the lubrication compensation control unit, promptly replenishing the lubricant in the compensating lubrication cavity 44 to ensure that it can enter the compensating groove through the conductive cotton and then act on the steel fiber through the compensating column 441.

[0054] Based on the data transmitted by the transition sensing unit, the forming collaborative processing unit determines the state of the steel fiber drawing forming data of the preceding forming mold 4. Before the collaborative control unit performs collaborative control on the mold control unit and the drawing speed control unit respectively, if the preceding data is judged to be in a small error, the friction forming auxiliary unit controls the electromagnetic insert in the compensation lubrication cavity 44 to generate a corresponding electromagnetic force, releasing and limiting the rotation gap of the compensation column 441 in the compensation groove. This effectively controls the drawing speed of a single forming mold 4, ensuring the quality of the preceding drawing forming while avoiding the impact of overall control on the production efficiency of the equipment body 1, effectively promoting the production quality of the equipment body 1 and ensuring its economic efficiency.

[0055] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
