Technical Field

[0001] This utility model belongs to the technical field of hydraulic hot pressing equipment, and particularly relates to a hot pressing device for a hot pressing hydraulic press. Background Technology

[0002] Hot presses, as core equipment for sheet metal bonding and part pressing in industrial production, achieve high-efficiency and labor-saving processing requirements thanks to their automated feeding system, stable hydraulic drive, and precise temperature control module. They are widely used in machinery manufacturing, electronic component assembly, and other fields. In the pressing of precision parts such as screws, existing hot presses typically use hydraulic cylinders to directly drive the hot press head to press the screw into the unloading hot press table, using the high-pressure output of the hydraulic system to fix or shape the part.

[0003] However, the aforementioned existing technology has the following shortcomings: because the driving force of the hydraulic cylinder acts directly on the screw, and there is a lack of an effective buffer adjustment structure, the instantaneous force on the screw during the pressing process is too large and concentrated. As a precision part, the screw has limited structural strength, and the instantaneous high pressure can easily cause the screw thread to deform, the shank to bend, or even break, seriously affecting the product qualification rate. Utility Model Content

[0004] The purpose of this utility model is to provide a hot pressing device for a hot pressing oil press, which aims to solve the technical problem that the instantaneous high pressure of the hot pressing device of the existing hot pressing oil press can easily cause screw thread deformation, rod bending or even breakage, which seriously affects the product qualification rate.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0035] In one embodiment of this utility model, such as Figures 1-4 As shown, a hot pressing device for a hot pressing hydraulic press is provided, including a hydraulic drive mechanism 1, a hot pressing mechanism 2, a guiding mechanism 3, a feeding mechanism 4, and a buffer mechanism 5. The hot pressing mechanism 2 is fixed to the hydraulic drive mechanism 1. The guiding mechanism 3 passes through the hydraulic drive mechanism 1 and the hot pressing mechanism 2 in sequence. The feeding mechanism 4 is fixed to the bottom of the guiding mechanism 3 and is located below the hot pressing mechanism 2. The buffer mechanism 5 is fixed to the feeding mechanism 4.

[0036] The buffer mechanism 5 includes a buffer platform 51 and a buffer assembly 52. ​​The buffer assembly 52 includes a buffer rod 521, a buffer guide cylinder 522, and a buffer spring 523. The buffer platform 51 is fixed to the feeding mechanism 4. The buffer rod 521 is fixed to both the buffer platform 51 and the feeding mechanism 4. The buffer guide cylinder 522 and the buffer spring 523 are sequentially movably inserted through the buffer rod 521 and fixedly connected to the buffer platform 51. One end of the buffer spring 523 is fixedly connected to the buffer guide cylinder 522, and the other end is fixedly connected to the feeding mechanism 4. Four buffer assemblies 52 are provided and evenly fixedly connected to the buffer platform 51.

[0037] In another embodiment of the present invention, the hydraulic drive mechanism 1 includes a hydraulic fixed seat 11, a hydraulic cylinder 12, and a cylinder connector 13. The hydraulic fixed seat 11 is fixedly connected to the guide mechanism 3, the hydraulic cylinder 12 is fixedly connected to the hydraulic fixed seat 11, and the cylinder connector 13 is fixedly connected to the hydraulic cylinder 12 and the hot pressing mechanism 2 respectively.

[0038] The hydraulic drive mechanism 1 operates as follows: The hydraulic system supplies oil to the hydraulic cylinder 12, increasing the pressure inside the hydraulic cylinder 121 and pushing the hydraulic piston rod 122 downward. The hydraulic piston rod 122 transmits the driving force to the hot press seat 21 of the hot press mechanism 2 through the cylinder joint 13 with the end thread. Under the action of the driving force, the hot press seat 21 slides smoothly downward along the guide rod 31 of the guide mechanism 3 through the guide blocks 32 on both sides, driving the bottom hot press head 22 to move downward synchronously until the hot press head 22 contacts the screw in the unloading hot press table 41 and completes the pressing. After pressing, the hydraulic cylinder 12 is depressurized, and the hydraulic piston rod 122 retracts upward under the action of the reset force (or the hydraulic system supplies oil in reverse). Through the cylinder joint 13, it pulls the hot press seat 21 upward along the guide rod 31 to reset and return to the initial position, waiting for the next processing cycle.

[0039] In another embodiment of the present invention, the hydraulic cylinder 12 includes a hydraulic cylinder body 121 and a hydraulic piston rod 122. The hydraulic cylinder body 121 is fixedly connected to the hydraulic fixed seat 11, and one end of the hydraulic piston rod 122 is movably connected to the hydraulic cylinder body 121, while the other end is fixedly connected to the cylinder connector 13.

[0040] In another embodiment of the present invention, the hot pressing mechanism 2 includes a hot pressing base 21 and a hot pressing head 22. The hot pressing base 21 is fixedly connected to the cylinder connector 13 and movably passes through the guide mechanism 3. Two hot pressing heads 22 are provided and fixedly connected to the bottom side of the hot pressing base 21.

[0041] The working process of the hot pressing mechanism 2 is as follows: After the screw is fed into the hot pressing hole 412 of the hot pressing table 41 by the automated feeding system, the hot pressing mechanism 2 starts the temperature control module, and the two hot pressing heads 22 with built-in heating wires begin to heat up. The temperature sensor monitors the temperature of the hot pressing head 22 in real time until the preset processing temperature (usually 100-200℃) is reached. At the same time, it ensures that the temperature of the two hot pressing heads 22 is uniform, which is good for subsequent pressing. The hydraulic piston rod 122 of the hydraulic drive mechanism 1 extends downward and transmits the driving force to the hot pressing seat 21 fixedly connected to the cylinder joint 13 through the cylinder joint 13. Under the constraint of the guide mechanism 3, the hot pressing seat 21 slides smoothly downward along the guide rod 31 with the help of the guide blocks 32 fixed to the hot pressing seat 21 on both sides, which drives the two hot pressing heads 22 fixed at the bottom to move down synchronously and gradually approach the hot pressing table 41. Since the hot press head 22 coincides with the feeding hot press hole 412 of the feeding hot press table 41, the downward-moving hot press head 22 is precisely aligned with the screw in the feeding hot press hole 412. As the hot press seat 21 continues to move downward, the hot press head 22 contacts the screw head and applies pressure. At the same time, the buffer mechanism 5 activates its buffering function. The hot press head 22, while maintaining the preset temperature, smoothly transmits pressure to the screw, completing the pressing process (pressing time 3-5 seconds). The two hot press heads 22 operate synchronously, achieving simultaneous pressing of two screws. After pressing is completed, the hydraulic piston rod 122 retracts upward, pulling the hot press seat 21 upward along the guide rod 31 through the oil cylinder joint 13. The hot press head 22 rises synchronously with the hot press seat 21 to the initial position. At the same time, the hot press head 22 stops heating or maintains a heat preservation state, waiting for the next feeding to be completed before entering a new processing cycle.

[0042] In another embodiment of this utility model, the guiding mechanism 3 includes a guide rod 31 and a guide block 32. The guide rod 31 passes through the hydraulic fixing seat 11, the hot press seat 21, and the feeding mechanism 4 in sequence. The guide block 32 is movably passed through the guide rod 31 and is fixedly connected to the hot press seat 21. The guide rod 31 passes through the hydraulic fixing seat 11, the hot press seat 21, and the feeding mechanism 4 in sequence, forming a rigid guiding reference that runs through the upper and lower parts of the equipment, ensuring that the hot press seat 21 can only move up and down along the axial direction of the guide rod 31. At the same time, the guide block 32, which is fixed to the hot press seat 21, is movably sleeved on the guide rod 31, further constraining the movement trajectory of the hot press seat 21, preventing it from deviating or tilting during the lifting and lowering process, and ultimately ensuring that the two hot press heads 22 on the bottom side of the hot press seat 21 can always accurately coincide with the feeding hot press hole 412 of the feeding hot press table 41, thus solving the problem of misalignment during pressing.

[0043] In another embodiment of this utility model, the feeding mechanism 4 includes a feeding hot press table 41, a hot press support 42, and a hot press base 43. The feeding hot press table 41 is fixedly connected to the top side of the buffer table 51. The hot press support 42 is disposed below the buffer table 51, and the hot press support 42 and the buffer table 51 are spaced apart to form a buffer gap. The hot press base 43 is fixedly connected to the bottom side of the hot press support 42 and is also fixedly connected to the bottom of the guide rod 31. A feeding hot press groove 411 is provided in the middle of the feeding hot press table 41, and two feeding hot press holes 412 are provided in the feeding hot press groove 411. The feeding hot press holes 412 coincide with the hot press head 22.

[0044] The hot pressing device of the hot pressing hydraulic press provided in this application operates as follows:

[0045] Material feeding stage: The screws to be pressed are fed one by one into the feeding hot pressing hole 412 of the feeding hot pressing table 41 by the automated feeding system. The screw head fits against the bottom of the feeding hot pressing groove 411 to achieve precise positioning.

[0046] Preheating stage: The temperature control module of the hot pressing mechanism 2 is activated, and the hot pressing head 22 begins to heat to the preset temperature (set according to the screw material and pressing requirements, usually 100-200℃). The temperature sensor provides real-time temperature data to ensure uniform heating.

[0047] Pressing Stage: Hydraulic cylinder 12 is activated, and hydraulic piston rod 122 extends downward, driving hot press base 21 to move downward along guide rod 31 via cylinder connector 13; hot press head 22 descends synchronously with hot press base 21, gradually approaching the screw inside discharge hot press hole 412. When hot press head 22 contacts the screw head, downward pressure is applied. At this time, buffer table 51 is subjected to downward force, causing buffer guide cylinder 522 to slide downward along buffer rod 521. Buffer spring 523 is compressed, and the elastic force gradually increases, offsetting part of the instantaneous impact force. Pressure transmission is gradual, with the pressure on the screw gradually increasing from 0 to a preset pressure (10-15MPa) and maintained for a preset time (3-5 seconds), completing the pressing process.

[0048] Reset phase: After pressing is completed, the hydraulic cylinder 12 is depressurized, the hydraulic piston rod 122 retracts upward, and the hot press seat 21 is reset upward along the guide rod 31 under the drive of the hydraulic cylinder 12; the buffer spring 523 returns to its original shape under the action of elastic force, pushing the buffer platform 51 to reset upward to the initial position.

[0049] Material unloading stage: The automated feeding system removes the pressed screws and simultaneously feeds in new screws to be processed, thus entering the next processing cycle.

[0050] 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.
