Description

Technical Field

[0001] This utility model relates to the technical field of lifting shaft processing equipment, and in particular to a multi-point temperature-controlled hammer head device for precision forging of lifting shafts. Background Technology

[0002] A multi-point temperature-controlled hammer head device for precision forging of lifting shafts is a core equipment component specifically applied to the precision forging process of lifting shafts. By precisely controlling the temperature of different areas of the hammer head, it achieves differentiated temperature adjustment of different parts during lifting shaft forging, thereby ensuring that the metal flow lines of the lifting shaft are reasonably distributed and the internal structure is uniform during the forging process, which greatly improves the mechanical properties and dimensional accuracy of the lifting shaft and meets the high precision and high strength requirements of high-end mechanical equipment for lifting shafts.

[0003] Traditional multi-point temperature control hammer head devices mainly consist of hammer head, hammer head base, and temperature sensor. When the device is started, the hammer head continuously strikes the metal billet. During this process, oxide scale will continuously be generated and fall off. If not treated in time, the oxide scale will embed into the surface of the forging, causing defects such as pits and pits, reducing surface quality and appearance.

[0004] Existing technology has improved the bottom of the device by installing a collection device with a fan at the bottom of the device. The wind power blows the oxide scale away from the forging table, which reduces the contact between oxide and metal billet to a certain extent and improves the quality of the forged product. In reality, after long-term use, the hammer head will deform due to wear, affecting the uniform transmission of striking force. Replacement requires unscrewing multiple screws, which is complicated and reduces the practicality of the device. Utility Model Content

By controlling the pull rod 204 to move the locking block 206 in and out of the locking groove 207, the forging hammer 8 can be fixed and disassembled. A collection mechanism 3 at the top of the base 1 is used to collect waste materials generated during the forging process. The temperature control component 9 installed on the outer wall of the mounting mechanism 7 controls the temperature of the forging hammer 8 to ensure that it operates at a suitable temperature to meet the requirements of precision forging of the hanging shaft.

[0038] Reference Figure 1 , Figure 2 and Figure 6 The collection mechanism 3 includes a collection box 301, providing a centralized storage space for waste. The bottom of the collection box 301 is fixedly connected to the top center of the base 1, ensuring the stability of the collection box 301 during operation.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The mounting mechanism 7 includes a fixed base 701, which provides a mounting foundation and positioning support for components such as the fixed ring 201. The inner wall of the fixed base 701 is slidably connected to the outer wall of the fixed ring 201, facilitating position adjustment of the fixed ring 201 and its connected forging hammer 8 during installation and debugging. A connecting plate 702 is fixedly connected to the top of the fixed ring 201, transmitting the power of the cylinder 6 to the fixed ring 201 and the connected forging hammer 8. The top of the connecting plate 702 is fixedly connected to the bottom end of the cylinder 6, ensuring that the cylinder 6 can stably drive the forging hammer 8 to move up and down during forging. A connecting rod 703 is provided on the right side of the outer wall of the fixed base 701, enhancing the overall stability of the mounting mechanism 7. Insert rods 704 are fixedly connected to the front and rear sides of the left end of the connecting rod 703, further strengthening the connection strength between components such as the fixed base 701 and the connecting plate 702. Both insertion rods 704 have their left sides extending through the connecting plate 702 and the fixing seat 701, ensuring that the components of the mounting mechanism 7 will not easily loosen when subjected to the impact force during the forging process. Nuts 705 are threaded onto the left ends of both insertion rods 704 to ensure the secure connection between the insertion rods 704 and the connecting plate 702 and fixing seat 701, preventing the insertion rods 704 from loosening and falling off during device operation.

[0042] Two connecting seats 10 are fixedly connected to the top left and right sides of the base 1 to enhance the connection stability between the column 4 and the base 1. The adjacent sides of the multiple connecting seats 10 are fixedly connected to the corresponding columns 4 to ensure the stability of the entire frame structure and to withstand various forces during the forging process without deformation or tipping over.

[0043] Specifically, the inner wall of the fixed base 701 is slidably connected to the outer wall of the fixed ring 201, allowing the fixed ring 201 to slide relative to the fixed base 701, facilitating fine-tuning of the forging hammer 8's position, and providing support. The connecting plate 702 at the top of the fixed ring 201 is connected to the bottom of the cylinder 6, enabling the cylinder 6 to drive the fixed ring 201 and the forging hammer 8 to move up and down, meeting forging requirements. The connecting rod 703 on the right side of the outer wall of the fixed base 701 has inserts 704 on the front and rear sides of its left end that pass through the connecting plate 702 and the fixed base 701, and are secured by a nut 705 threaded on the left end, firmly connecting all components into one unit, ensuring structural stability and preventing components from loosening under forging impact.

[0044] The connecting seats 10 on the top left and right sides of the base 1 are fixed to the corresponding columns 4 respectively, which strengthens the connection between the columns 4 and the base 1, so that the whole device can withstand the force generated by the movement of the forging hammer 8 when working, and ensures the stable operation of the device.

[0045] Reference Figure 1 , Figure 4 and Figure 5 The temperature control assembly 9 includes a second fixing ring 901, which provides a carrier for the installation and positioning of other temperature control components. The inner wall of the second fixing ring 901 is fixedly connected to the outer wall of the fixing base 701, ensuring that the temperature control probe 903 is always in a suitable position for monitoring the temperature of the forging hammer 8. Mounting grooves 902 are provided around the bottom of the second fixing ring 901 to regulate the installation position of the temperature control probe 903 and the second spring 904, ensuring their accuracy and stability. Temperature control probes 903 are connected to the inner walls of multiple mounting grooves 902, providing data for temperature control during the forging process and ensuring that forging is carried out within a suitable temperature range. Springs 904 are fixedly connected to the tops of multiple temperature control probes 903, allowing the temperature control probes 903 to flexibly adjust their position within a certain range to better adapt to the movement of the forging hammer 8 and changes in the temperature field, ensuring the accuracy of temperature monitoring. The tops of multiple springs 904 are fixedly connected to the top of the inner wall of the corresponding mounting groove 902 to maintain the normal working state of the temperature control probe 903 and prevent it from affecting the temperature monitoring effect due to vibration or displacement.

[0046] Multiple guide rods 11 are fixedly connected to the bottom of the top plate 5 to guide the up-and-down movement of the fixed base 701, ensuring that the fixed base 701 and the connected forging hammer 8 can move along a predetermined trajectory. All guide rods 11 are slidably connected to the fixed base 701 to ensure the stability of the forging hammer 8 during its up-and-down movement, reducing swaying and deviation. Buffer blocks 12 are fixedly connected to the middle of the outer wall of each guide rod 11. During the up-and-down movement of the fixed base 701, when it reaches a certain position, buffering the impact between the fixed base 701 and other components, protecting the device components from damage caused by excessive impact.

[0047] Two baffles 13 are fixedly connected to the front right side of the outer wall of the collection box 3051. These baffles cooperate with the rotating rods 14 on the rotating cover 3052 to limit and fix the rotating cover 3052. Two rotating rods 14 are rotatably connected to the outer right side of the rotating cover 3052. These rods engage with the baffles 13, keeping the rotating cover 3052 closed when it is closed, preventing waste from overflowing from the collection box 3051. The two rotating rods 14 engage with their corresponding baffles 13 to ensure the sealing of the collection box 3051 during waste collection, ensuring the normal operation of the waste collection process.

[0048] Specifically, the inner wall of the fixing ring 901 is fixed to the outer wall of the fixing seat 701. A temperature control probe 903 is slidably connected within the mounting grooves 902 around its bottom. The top of the probe is connected to the top of the mounting grooves 902 via a spring 904. The spring 904 allows the temperature control probe 903 to flexibly adapt to position changes and always maintain a suitable distance from the forging hammer 8, accurately measuring the temperature and enabling temperature monitoring of the forging hammer 8 to ensure suitable forging temperature. The guide rod 11 at the bottom of the top plate 5 is slidably connected to the fixing seat 701, providing guidance for the up-and-down movement of the fixing seat 701 and the connected forging hammer 8, ensuring smooth movement. The buffer block 12 in the middle of the guide rod 11 acts as a buffer when the fixing seat 701 moves, reducing impact and protecting the device components. The baffle 13 on the right side of the front end of the collection box 3051 engages with the rotating rod 14 on the right side of the rotating cover 3052. When the rotating cover 3052 is closed, the rotating rod 14 engages with the baffle 13 to prevent the rotating cover 3052 from opening accidentally, ensuring the sealing of the collection box 3051 during the waste collection process and preventing waste from overflowing.

[0049] Working principle: When it is necessary to replace the forging hammer 8, first remove the temperature control component 9 and the mounting mechanism 7, pull the pull rod 204 to move the locking block 206 outward to compress the spring 205, so that the locking block 206 is disengaged from the slot 207 to release the restriction on the forging hammer 8 and remove it. Then, align the new forging hammer 8 with the fixing ring 201 and push it upward. When the slot 207 is aligned with the sliding groove 203, the locking block 206 is locked into the slot 207 under the action of the spring 205 to complete the fixation. Finally, start the cylinder 6 to drive the mounting mechanism 7 and the guide rod 11 to move up and down.

[0050] Furthermore, during the precision forging of the hanging shaft, the forging hammer 8 inevitably produces oxide scale when striking the metal billet. This oxide scale naturally falls into the collection box 301 located at the top center of the base 1. At this time, the fans 302 on the left and right sides of the rear end of the outer wall of the collection box 301 are activated. The fans 302 generate airflow, blowing the oxide scale in the collection box 301 towards the front of the box. Then, the fans 303 on the left and right sides of the outer wall of the collection box 301 activate, further blowing the oxide scale that has been blown to the front into the collection box 3051 connected to the front side of the outer wall of the collection box 301. The baffle 304 fixedly connected to the top front of the collection box 301 can effectively prevent oxide scale from being blown out of the collection box 301, ensuring that the oxide scale is collected in the designated area. When it is necessary to clean the oxide scale, the operator only needs to hold the handle 3053 fixedly connected to the right side of the outer wall of the rotating cover 3052, rotate to open the rotating cover 3052, and can easily clean the oxide scale accumulated inside the collection box 3051, thus completing the entire oxide scale collection and cleaning process.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
