Description

Technical Field

[0001] This utility model relates to the technical field of iron handicraft production equipment, and in particular to a shaping device for iron handicrafts. Background Technology

[0002] Iron handicrafts are handicrafts or ornaments made primarily of iron through processes such as forging, welding, and surface treatment. They combine practicality and artistry. After the iron handicrafts are welded, workers need to shape them.

[0003] For example, for ring-shaped iron crafts, after welding is completed, they are usually placed on a mold and then manually hammered to make the outer surface of the iron crafts smoother and flatter.

[0004] Because iron handicrafts are circular, workers need to strike them by rotating them 360°, or by placing them on a rotating platform and striking them manually. However, this method of shaping relies entirely on the worker's experience for the striking force and frequency at each location. Furthermore, when workers are exhausted from long hours of work, the striking force can become unbalanced, resulting in an uneven surface. Additionally, as the handicraft cools during the striking process, its outer surface hardens and becomes unable to deform under the worker's strikes, leading to an unsatisfactory final shaping result and a higher probability of defective products. Utility Model Content

[0025] Reference Figure 1 and Figure 2A shaping device for iron handicrafts 2 includes a machine base 1 and a handicraft 2. The machine base 1 includes a table and a base, with the base welded to the bottom of the table. A vertically penetrating mounting groove is provided in the middle of the table. A power supply (not shown in the figure) is also fixedly installed on the side of the table. A worktable 3 is vertically movable in the mounting groove of the machine base 1. A shaping table 4 is rotatably mounted on the worktable 3 and equipped with a motor (not shown in the figure) for driving the shaping table 4 to rotate. This motor may include, but is not limited to, a stepper motor or a servo motor. The motor is fixedly mounted in the middle of the worktable 3 by a bracket, and its rotating head is fixedly connected to the bottom of the shaping table 4. The circuit is connected to the power supply. A detachable mold 5 for fixing the craft item 2 is fixed on the shaping table 4. A height-adjustable mounting bracket 6 is also fixed on the machine base 1. One end of the mounting bracket 6 is located directly above the mold 5, and an electrically retractable hammer 7 is fixed thereon. When the hammer 7 is at its longest point, it presses against the craft item 2. Its electric retraction device is an electric push rod, which is connected to the power supply via a circuit. The machine base 1 is also equipped with an electromagnetic heating coil 8. The electromagnetic heating chamber uses the principle of electromagnetic induction to generate eddy currents inside the workpiece for heating, achieving non-contact heating. This method offers advantages such as high efficiency, energy saving, and precise temperature control. In this configuration, the electromagnetic heating coil 8 is connected to a power source via a circuit, and the shaping mold 5 is located in the middle of the electromagnetic heating coil 8. With this setup, after the iron craft 2 is welded, it is fixed to the shaping table 4 using the shaping mold 5. The height of the mounting bracket 6 is adjusted so that the hammer 7, when extended to its longest end, can press against the craft 2. Then, the power switch is turned on, and the power supply sequentially energizes the motor driving the shaping table 4, the electromagnetic heating coil 8, and the electric push rod. At this time, the shaping table 4 begins to rotate the craft 2, the electric heating coil begins to heat the outer surface of the craft 2, and simultaneously, the hammer 7 operates against the electric push rod. The upper part of the craft item 2 is struck by the hammer. By setting the rotation speed of the shaping table 4 to match the striking frequency of the hammer 7, the hammer 7 can strike every part of the upper part of the craft item 2 evenly. During the striking process, the craft item 2 undergoes plastic deformation under the impact force. The micro-grains are squeezed and rearranged, the grain boundary area increases, and the surface roughness decreases. In addition, the vibration generated during the striking can effectively remove defects such as oxide scale, welding slag, and burrs from the surface of the craft item 2. Therefore, under the continuous striking of the hammer 7, the structure of the craft item 2 can become more compact, which can not only further improve its strength, but also make the outer surface smoother and flatter.

[0026] In this way, not only does the shaping table 4 drive the craft 2 to rotate 360°, but the electric telescopic hammer 7 replaces manual hammering, which can maintain the same frequency and force for a long time. Therefore, the surface of the craft 2 will not become rough due to the imbalance of hammering force. At the same time, the electromagnetic heating coil 8 continuously heats the surface of the craft 2, which also avoids the situation where the hammering effect is not ideal due to the gradual cooling of the craft 2 during long-term hammering.

[0027] In one specific embodiment, the shaping mold 5 is fixed to the shaping table 4 by bolts, and the size of the shaping mold 5 can be changed according to the size of the craft 2. Meanwhile, the entire machine base 1, workbench 3, shaping table 4 and shaping mold 5 are all made of aluminum or copper. Aluminum is a typical non-ferromagnetic metal with extremely low magnetic permeability. The eddy current effect generated in the alternating magnetic field is extremely weak, so it will not be induction heated. Copper has extremely high resistivity. Although it can generate eddy currents, its heating efficiency is low. Therefore, the machine base 1, workbench 3, shaping table 4 and shaping mold 5 will not be heated under the action of electromagnetic heating coil 8.

[0028] Reference Figure 2 At least one slide rail 9 is fixedly mounted on the bottom surface of the machine base 1. A sliding block 10 is slidably mounted on the slide rail 9, and a positioning mechanism is provided to limit the sliding block 10. A shaping pressure block 11 is detachably fixed at one end of the sliding block 10 near the worktable 3. When the worktable 3 descends, the shaping pressure block 11 presses against the side of the craft item 2. With this configuration, before striking the craft item 2, the worktable 3 is first controlled to descend, and then the sliding block 10 is slid so that the shaping pressure block 11 can press against the outer surface of the craft item 2. The position of the sliding block 10 is then fixed by the positioning mechanism. Next, the worktable 3 is controlled to rise to start the striking process. After the craft item 2 is struck... The worktable 3 is lowered and the power supply to the electric push rod is stopped. When the shaping block 11 presses against the outer surface of the craft 2, the worktable 3 stops lowering. At this time, as the craft 2 rotates, the shaping block 11 continuously presses against and polishes the outer surface of the craft 2. Through micro-cutting action, the outer surface of the craft 2 is smoothed. This not only removes residual impurities from the outer surface of the craft 2 and further improves its smoothness and flatness, but also allows the craft 2 to complete the final shaping under the pressure of the shaping block 11. Every once in a while, the worktable 3 is lowered a certain distance so that the outer surface of the craft 2 can be evenly pressed by the shaping block 11.

[0029] In one specific embodiment, two symmetrical limiting strips are fixed on both sides of the worktable 3, and a limiting groove is opened on the machine base 1. The limiting strips are slidably embedded in the limiting grooves. Furthermore, the rack is located in the middle between the two limiting strips. In this way, the limiting strips can play a guiding role and apply a longitudinal binding force to the worktable 3, so that the worktable 3 can only perform up and down lifting movements.

[0030] Reference Figure 1 The mounting bracket 6 includes a fixed end 601, a sliding end 602, and a support end 603. One end of the fixed end 601 is fixed to the machine base 1, and the other end is slidably fitted onto the sliding end 602. Both the fixed end 601 and the sliding end 602 have several screw holes, which are fixed by through bolts. One end of the support end 603 is fixed to the sliding end 602, and the other end is fixedly connected to the hammer 7. With this configuration, the height of the support end 603 can be adjusted by adjusting the overlap length of the fixed end 601 and the sliding end 602, thereby adjusting the height of the hammer 7. After adjusting to the appropriate height, the bolts are locked into the screw holes where the fixed end 601 and the sliding end 602 overlap, thus fixing the height of the mounting bracket 6.

[0031] In one specific embodiment, the sliding end 602 and the bracket end 603 form a 90° right angle, and the sliding end 602 and the bracket end 603 are integrally formed, which further strengthens the overall strength of the mounting bracket 6 and improves the stability of the hammer 7 during operation.

[0032] Reference Figure 1 The shaping mold 5 includes an inner mold 501 and an outer mold 502. The inner mold 501 is detachably fixed to the shaping table 4, and the outer mold 502 is fitted onto the outside of the craft item 2. In this configuration, the inner mold 501 matches the inner diameter of the craft item 2, and the outer mold 502 matches the outer diameter of the craft item 2. In use, the inner mold 501 is locked and fixed to the shaping table 4 with bolts, and then the craft item 2 is fitted onto the outside of the inner mold 501. Finally, the outer mold 502 is fitted onto the outside of the craft item 2. When the vibrating hammer strikes the craft item 2 downwards, the outer mold 502 can restrict the lateral deformation of the craft item 2, thereby allowing the craft item 2 to only undergo downward plastic deformation, in order to further ensure the overall strength of the craft item 2.

[0033] Reference Figure 2 At least one air blower 12 is fixedly installed on the bottom surface of the machine base 1. The air outlet of the air blower 12 faces the shaping block 11. With this setting, while the shaping block 11 is pressing against the craft product 2, the air blower 12 can simultaneously blow air to cool it down, so that the craft product 2 cools down and is completely shaped after being pressed by the shaping block 11. In this way, when the entire craft product 2 has completed the final pressing process by the shaping block 11, it has also cooled down to a low temperature, and the workers do not need to wait for it to cool down for a long time before taking it out, which effectively improves work efficiency.

[0034] In one specific embodiment, four shaping blocks 11 are provided and arranged in a cross shape, and four air blowers 12 are also provided. Each air blower 12 is located in the middle between two shaping blocks 11, so the shaping blocks 11 and the air blowers 12 are arranged in a ring shape to further improve work efficiency.

[0035] Reference Figure 2The positioning mechanism includes a positioning hole 13, a positioning element 14, and several positioning slots 15. The positioning hole 13 is located in the middle of the shaping block 11, and the positioning slots 15 are located on the bottom surface of the worktable 3 and are evenly distributed. The positioning element 14 passes through the positioning hole 13 and is embedded in the positioning slot 15. With this configuration, when the position of the shaping block 11 is adjusted, the positioning element 14 passes through the positioning hole 13 and is embedded in the positioning slot 15 to fix the shaping block 11.

[0036] In one specific embodiment, the positioning member 14 and the positioning slot 15 are provided with matching threads. When the positioning member 14 is inserted into the positioning slot 15, it can be rotated and locked, which further improves the stability of the shaping pressure block 11 when it is fixed.

[0037] Reference Figure 1 The bottom of the machine base 1 is equipped with a hydraulic cylinder, the piston rod of which abuts against the worktable 3. With this setup, the up and down movement of the worktable 3 can be controlled manually by operating the piston rod of the hydraulic cylinder, ultimately causing the rack and pinion to drive the worktable 3 up and down. Through manual control, the operating strategy can be dynamically adjusted according to real-time environmental changes and complex needs. For example, when the shaft diameter of the crafts 2 is different, the time it needs to be pressed against by the shaping block 11 at the same height will also be different. Secondly, when the working environment becomes more humid or drier due to weather conditions, affecting the outer surface of the crafts 2, the time the crafts 2 is pressed against by the shaping block 11 also needs to be changed. After such situations occur, under manual operation, the worker can directly adjust the lifting time of the worktable 3 based on their own experience without reading the parameters. In the event of an accident, the worker can also make a quick decision based on experience.

[0038] Regarding the workload, the process of workers needing to rotate the craft item 2 while hammering it has been transformed into a process where workers only need to adjust the frequency and force of the hammering hammer 7, the rotation speed of the shaping table 4, and the heating temperature of the electromagnetic heating coil 8 according to the size of the craft item 2. Then, the worktable 3 is raised and lowered so that the craft item 2 is pressed by the shaping block 11 to complete the shaping process. This effectively reduces the workload. In terms of work efficiency, the craft item 2 can be hammered with the same force during a long working period, making the outer surface of the craft item 2 smoother. Moreover, the final pressing, polishing, and cooling shaping process ensures that the work item is basically cooled after being thoroughly shaped, eliminating the need for workers to wait for a long time. Therefore, this invention is a significant improvement over existing shaping devices.
