Description

Technical Field

[0001] This utility model relates to the field of hot upsetting technology, and specifically to an automatic mold moving device for hot upsetting. Background Technology

[0002] Hot upsetting, a core technology in modern metal processing, plays a crucial role in manufacturing due to its high efficiency and precision. Hot upsetting technology is based on the plastic deformation characteristics of metals at high temperatures. By heating the metal material above its recrystallization temperature, the material softens and gains high plasticity. Pressure is then applied in a mold, causing precise plastic deformation under the mold's constraints, thus forming a part of the desired shape. This process fully utilizes the metal's good plasticity and low deformation resistance at high temperatures, making the processing more efficient and precise.

[0003] However, a series of technical problems and challenges arise when using hot upsetting technology to process workpieces, especially long ones. These challenges mainly stem from the inherent limitations of the equipment's travel, making it impossible to directly and smoothly place long workpiece blanks into the mold cavity for subsequent hot upsetting operations. To overcome this obstacle, existing processes have to adopt a relatively cumbersome and inefficient method: first, the mold needs to be moved out of the working position; then, the operator manually places the long blank into the mold cavity; finally, the mold is moved back to the working position for hot upsetting.

[0004] While this process can meet the processing needs of long workpieces to some extent, its drawbacks and shortcomings are equally obvious. On the one hand, the added steps of mold removal and placement make the entire processing flow more lengthy and complex, resulting in a significant reduction in processing efficiency. On the other hand, this process requires frequent manual intervention from operators, which not only greatly increases the intensity and burden of manual operation, but also may cause potential safety hazards due to improper operation or negligence, threatening the safety of operators. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an automatic mold moving device that significantly reduces reliance on manual operation, improves operational safety, and greatly increases production efficiency during the hot forging process of workpieces, especially long-sized workpieces.

[0006] To solve the above-mentioned technical problems, the present invention provides an automatic mold-moving device for hot upsetting, comprising at least:

[0007] A base plate, wherein the base plate is provided with at least one guide block;

[0008] A mold assembly, the mold assembly comprising at least a slider located on the surface of the base plate and adapted to be connected to the guide block, a mold box mounted on the side of the slider away from the base plate and having a cavity structure, and a mold adapted to the cavity structure;

[0009] A drive assembly for driving the slider to slide relative to the base plate along the guide block.

[0010] In a preferred embodiment, the base plate is provided with a relief groove arranged parallel to the guide block, the slider is provided with a support block having one end passing through the relief groove, and the support block is provided with a first inner cavity communicating with the mold cavity.

[0011] In a preferred embodiment, a pad is installed between the bottom of the cavity structure and the bottom of the mold, and the end of the mold away from the pad extends out of the cavity structure.

[0012] In a preferred embodiment, the mold assembly further includes a fixing block that covers the mold and is fixedly connected to the mold box. The fixing block is provided with a second inner cavity adapted to the outer surface of the mold and an opening that matches the mold cavity.

[0013] In a preferred embodiment, the outer surface of the fixing block is provided with at least one cooling water pipe that communicates with the second inner cavity.

[0014] In a preferred embodiment, a first positioning sensor for detecting the workpiece position is provided at the end of the first inner cavity away from the slider.

[0015] In a preferred embodiment, the guide block includes a first guide block and a second guide block arranged in parallel. The first guide block, the second guide block, and the base plate form a groove that gradually narrows along the sliding direction of the slider. The slider is adapted to the groove.

[0016] In a preferred embodiment, the guide block is provided with a graphite copper sheet adapted to the slider on the side near the slider.

[0017] In a preferred embodiment, the graphite copper sheet protrudes outward on the side near the guide block to form several positioning portions. The guide block is provided with grooves that are adapted to the positioning portions. On the side of the guide block away from the graphite copper sheet, several threaded holes and screws corresponding to the threaded holes are provided at intervals. One end of the screw passes through the threaded hole to press the graphite copper sheet against the surface of the slider.

[0018] In a preferred embodiment, the base plate is provided with a second positioning sensor and a third positioning sensor along the sliding direction of the slider for detecting the moving position of the slider.

[0019] The automatic mold-moving device for hot upsetting of this invention has the following advantages compared with the prior art:

[0020] (1) The automatic mold-moving device of this utility model is designed for hot forging. Its structure includes at least three main parts: a base plate, a mold assembly, and a drive assembly. At least one guide block is provided on the base plate to ensure the accuracy of mold movement. The mold assembly includes a slider that fits against the surface of the base plate and closely cooperates with the guide block, a mold box mounted on the side of the slider away from the base plate and having an internal cavity structure, and a mold adapted to the cavity structure. This structural design ensures the stability and reliability of the mold. The drive assembly is responsible for driving the slider to slide along the guide block on the base plate, thereby realizing the automatic removal and insertion of the mold. The innovation of this automatic mold-moving device lies in its full automation of mold movement through the drive assembly, greatly reducing the physical burden on operators and lowering the intensity of manual operation. At the same time, this automation process effectively avoids safety risks that may be caused by improper operation or negligence, significantly improving the safety and efficiency of hot forging operations and providing a strong guarantee for high-quality production of workpieces.

[0021] (2) This utility model relates to an automatic mold-moving device for hot upsetting. The base plate is provided with a relief groove parallel to the guide block. The slider has a support block with one end passing through the relief groove. The support block has a first inner cavity communicating with the mold cavity. This structural design provides ample space for long workpieces. During hot upsetting, workpieces often have long dimensions due to processing requirements, and traditional mold designs may struggle to effectively support or accommodate such workpieces. This utility model successfully solves this problem through the first inner cavity within the support block, allowing long workpieces to be stably placed in the mold and ensuring smooth processing. Furthermore, this structural design greatly improves processing flexibility and adaptability. Because the first inner cavity communicates with the mold cavity, the mold can easily adapt to workpieces of different lengths and shapes, eliminating the need for frequent mold changes or equipment adjustments, thus significantly improving production efficiency. In addition, the support block, through the relief groove and cooperation with the base plate, effectively prevents mold shaking or displacement during processing.

[0022] (3) The automatic mold-moving device for hot forging of this utility model has a pad installed between the bottom of the cavity structure and the bottom of the mold, which allows different models of molds to be more flexibly adapted to the mold box. This design enhances the versatility of the device and reduces the need to replace the entire mold box or make complex adjustments due to different mold models. The mold assembly also includes a fixing block that covers the mold and is fixedly connected to the mold box. The fixing block is provided with a second inner cavity that matches the outer surface of the mold and an opening that matches the mold cavity. This structure ensures the stability of the mold during the hot forging process and prevents the mold from shifting due to vibration or external force, thereby improving processing accuracy and product quality. At least one cooling water pipe connected to the second inner cavity is provided on the outer surface of the fixing block. Cooling water is transported to the mold surface through the cooling water pipe, which effectively reduces the temperature of the mold during the hot forging process, reduces the thermal stress, thermal fatigue and wear caused by high temperature, and thus significantly extends the service life of the mold.

[0023] (4) The automatic mold-moving device for hot upsetting of this utility model has a first positioning sensor for detecting the workpiece position at the end of the first inner cavity away from the slider. A second positioning sensor and a third positioning sensor for detecting the slider's movement position are arranged on the base plate along the slider's sliding direction. Through the second and third positioning sensors, the slider's moving distance and speed are precisely controlled, ensuring the mold is accurately positioned during the hot upsetting process, further improving the stability and consistency of the processing. Operators can easily monitor the position of the workpiece and slider through the signals fed back by the sensors, eliminating the need for tedious manual inspection and adjustment. This not only reduces the burden on operators but also improves production efficiency and safety. Attached Figure Description

[0037] This embodiment provides an automatic mold-moving device for hot upsetting, such as... Figure 1 and Figure 2As shown, the assembly includes at least a base plate 1, a mold assembly 2, and a drive assembly 3. The base plate is equipped with at least one guide block 11 to ensure the accuracy of mold movement. The mold assembly includes at least a slider 21 located on the surface of the base plate and adapted to the guide block, a mold box 22 mounted on the side of the slider away from the base plate and having a cavity structure 221, and a mold 23 adapted to the cavity structure, ensuring the stability and reliability of the mold. The drive assembly drives the slider 21 to slide relative to the base plate 1 along the guide block, thereby achieving automatic mold movement. The drive assembly achieves full automation of mold movement, greatly reducing the physical burden on operators and lowering the intensity of manual operation. Simultaneously, this automation process effectively avoids safety risks that may result from improper operation or negligence, significantly improving the safety and efficiency of hot forging operations and providing strong support for high-quality workpiece production.

[0038] In this embodiment, the drive assembly 3 includes a drive element 31 whose output end is connected to the slider and a mounting plate 32 for mounting the drive element. The drive element 31 includes a cylinder, a hydraulic cylinder, and a linear motor. In this embodiment, a hydraulic cylinder is used.

[0039] The base plate 1 is provided with a relief groove 12 parallel to the guide block, and the slider 21 is provided with a support block 211 with one end passing through the relief groove. The support block has a first inner cavity 2111 that communicates with the mold cavity of the mold 23. This structural design provides ample space for long workpieces. During hot forging, workpieces often have long dimensions due to processing requirements, and traditional mold designs may struggle to effectively support or accommodate such workpieces. The embodiment shown in this invention successfully solves this problem through the first inner cavity within the support block, allowing long workpieces to be stably placed in the mold and ensuring smooth processing. Furthermore, this structural design greatly improves processing flexibility and adaptability. Since the first inner cavity communicates with the mold cavity, the mold can easily adapt to workpieces of different lengths and shapes, eliminating the need for frequent mold changes or equipment adjustments, thus significantly improving production efficiency. In addition, the support block, through the relief groove and cooperation with the base plate, effectively prevents mold wobbling or displacement during processing.

[0040] In this embodiment, a first positioning sensor 2112 for detecting the position of the workpiece is provided at the end of the first inner cavity 2111 away from the slider. When the workpiece is placed into the first inner cavity, the first positioning sensor acquires the position data of the workpiece and transmits the position data to the control center.

[0041] A pad 24 is installed between the bottom of the cavity structure 221 and the bottom of the mold 23. The end of the mold away from the pad extends out of the cavity structure, allowing different mold models to be more flexibly adapted to the mold box. This design enhances the versatility of the device and reduces the need to replace the entire mold box or make complex adjustments due to different mold models.

[0042] The mold assembly 2 also includes a fixing block 25 that covers the mold 23 and is fixedly connected to the mold box 22. The fixing block is provided with a second inner cavity 251 that matches the outer surface of the mold 23 and an opening 252 that matches the mold cavity, ensuring the stability of the mold during the hot forging process and preventing the mold from shifting due to vibration or external force, thereby improving processing accuracy and product quality. The outer surface of the fixing block 25 is provided with at least one cooling water pipe 253 connected to the second inner cavity 251. Cooling water is transported to the mold surface through the cooling water pipe, which effectively reduces the temperature of the mold during the hot forging process, reduces the thermal stress, thermal fatigue and wear caused by high temperature, and thus significantly extends the service life of the mold.

[0043] In this embodiment, the cooling water pipe includes two inlet pipes and two outlet pipes. The cooling water forms a cooling water circulation through the inlet pipes and outlet pipes to cool the mold 23 located in the second inner cavity 251.

[0044] like Figure 1 As shown, the guide block 11 includes a first guide block 111 and a second guide block 112 arranged in parallel. The first guide block, the second guide block and the base plate 1 form a groove 113 that is gradually narrowed along the sliding direction of the slider. The slider is adapted to the groove.

[0045] Preferably, the guide block 11 is provided with a graphite copper sheet 114 adapted to the slider 21 on the side near the slider, which increases the lubrication of the slider and plays a protective role.

[0046] The graphite copper sheet protrudes outward from the side near the guide block 11 to form several positioning parts 1141. The guide block is provided with grooves 115 that match the positioning parts, achieving a precise positioning effect. This design ensures the stability of the graphite copper sheet during assembly and avoids performance degradation or damage caused by positional misalignment.

[0047] The guide block has several threaded holes spaced apart on the side away from the graphite copper sheet, and screws 116 corresponding to each threaded hole. One end of the screw passes through the threaded hole, pressing the graphite copper sheet against the slider surface. By simply adjusting the tightness of the screws, the degree of compression of the graphite copper sheet can be controlled, thereby precisely adjusting the gap between it and the slider. This adjustability is crucial for meeting the needs of different operating conditions. When the graphite copper sheet wears or needs replacement, the screws can be easily removed for replacement or maintenance. This design reduces maintenance costs and time, improving the maintainability of the equipment. Moreover, the graphite copper sheet has good thermal conductivity; by tightly pressing against the slider surface, heat can be effectively conducted away from the slider, reducing the slider temperature and thus improving the stability and service life of the equipment.

[0048] Preferably, the base plate is equipped with a second positioning sensor 13 and a third positioning sensor 14 along the sliding direction of the slider for detecting the slider's movement position. These sensors precisely control the slider's movement distance and speed, ensuring accurate positioning of the mold during the hot forging process and further improving processing stability and consistency. Operators can easily monitor the position of the workpiece and slider using the signals from the sensors, eliminating the need for tedious manual inspection and adjustments. This not only reduces the operator's workload but also improves production efficiency and safety.

[0049] like Figure 3-4 As shown, the operating principle of an automatic mold-moving device for hot upsetting in this embodiment is as follows:

[0050] When the press reaches the top dead center, a trigger signal is sent to the control center. The control center then controls the drive element 31 to push the slider 21 along the guide block 11 relative to the base plate 1. When the slider reaches the unloading station, the third positioning sensor 14 detects the slider's position data and transmits it to the control center. The control center then controls the drive element 31 to stop working and sends an unloading signal.

[0051] According to the feeding signal, the operator places the workpiece 5 into the mold cavity. The first positioning sensor located in the first inner cavity 25 detects the position data of the workpiece and transmits the position data to the control center. The control center controls the drive element 31 to push the slider 21 to slide in the opposite direction relative to the base plate 1 along the guide block 11. The slider slides to the processing station, the second positioning sensor 13 detects the position data of the slider and transmits the position data to the control center. The control center controls the drive element 31 to stop working, controls the press 4 to perform hot forging and return to the top dead center.

[0052] In summary, the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
