Description

Technical Field

[0001] This utility model relates to the field of non-standard mechanical technology, and in particular to a casting mechanism for a multi-degree-of-freedom adjustable melting furnace. Background Technology

[0002] With the increasing automation of metallurgical enterprises, many jobs previously performed by workers have been replaced by robots and automated systems. However, due to limitations in process and equipment space layout, some existing casting systems are inflexible in operation, unable to be adjusted in position or degree of freedom, and therefore unsuitable for automated production. This prevents automation upgrades and leads to the obsolescence of the original furnace casting systems, resulting in significant resource waste. Therefore, improvements are needed. Utility Model Content

Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the multi-degree-of-freedom adjustable casting furnace mechanism in a specific embodiment of the present invention.

[0015] Figure 2 This is a schematic diagram showing the position of the pawl in a specific embodiment of the present invention. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] For example, refer to Figures 1 to 2 As shown, a multi-degree-of-freedom adjustable melting furnace casting mechanism includes a horizontally arranged base, a lifting seat slidably arranged on the base, a furnace 1 arranged on the top of the lifting seat, and a melting furnace casting pipe 2 connected to the furnace 1. The melting furnace casting pipe 2 is rotatably connected to the furnace 1.

[0018] In this technical solution, the base is horizontally set on the ground or workbench, and the lifting seat slides horizontally along the base to ensure that the furnace is always in a horizontal state. The horizontal movement of the furnace is achieved by the lifting seat sliding along the base, and the vertical movement of the furnace is achieved by the lifting and lowering of the lifting seat. The casting position is adjusted by rotating the furnace casting pipe. This utility model has a simple structure and can realize the horizontal and vertical movement of the furnace. With the 360° rotation adjustment of the furnace casting pipe, it meets the production requirements of the metal smelting and casting and metal forming control industries.

[0019] For example, refer to Figure 1 As shown, the base includes a support frame 3 and screws 4 at both ends that are rotatably mounted on the base via support seats.

[0020] In this technical solution, the support frame is a conventional structure such as a rectangular frame, depending on the working conditions of the production site. The support frame is made of conventional profiles such as square tubes or H-steel. The screw is a conventional screw or threaded rod, with conventional bearing seats at both ends serving as support seats and rotatably mounted on the top surface of the base. One end of the screw can be manually rotated by a wrench or connected to a servo motor through a coupling to achieve automatic rotation.

[0021] For example, refer to Figure 1 and Figure 2 As shown, the lifting seat includes an upper bracket 5 and a lower bracket 6 arranged opposite to each other, and a lifting device 7 disposed between the upper bracket 5 and the lower bracket 6. The lower bracket 6 is connected to the screw rod 4 by a threaded connection.

[0022] In this technical solution, there are four lifting devices, and existing structures such as hydraulic jacks are used. The bottom of the lifting device is fixed to the top surface of the lower bracket by conventional structures such as bolts, and the top of its piston rod is fixed to the upper bracket by conventional structures such as bolts. The upper bracket is driven to rise and fall by the lifting device, thereby realizing the vertical movement of the furnace. Both the upper and lower brackets are spliced ​​from profiles such as square tubes. The lower bracket is connected to a nut that mates with the screw or has threads that mate with the screw. During the rotation of the screw, the lower bracket is driven to move along the axial direction of the screw, thereby realizing the horizontal movement of the lifting device, that is, realizing the axial movement of the furnace along the bolt.

[0023] For example, refer to Figure 1 As shown, the bottom surface of the lower bracket 6 is provided with rollers 8 that roll on the base and / or guide rails (not shown) that are slidably connected to the base.

[0024] In this technical solution, the upper part of the long side of the rectangular support frame is used as the moving track for the rollers, so it requires certain strength, rigidity and flatness. A conventional linear guide rail can also be set between the lower bracket and the base to ensure the accuracy and stability of the lower bracket's movement.

[0025] For example, refer to Figure 1 and Figure 2 As shown, scissor brackets 9 are respectively provided on both sides between the upper bracket 5 and the lower bracket 6. The scissor brackets 9 include a first link and a second link that are hinged to each other. One end of the first link is hinged to the upper bracket 5, and the other end rolls against the lower bracket 6 through a first moving wheel. One end of the second link is hinged to the lower bracket 6, and the other end rolls against the upper bracket 5 through a second moving wheel.

[0026] In this technical solution, during the lifting process of the upper bracket driven by the lifting device, the scissor bracket composed of the first link and the second link opens or closes, and the first moving wheel and the second moving wheel roll against the lower bracket and the upper bracket respectively, thereby improving the stability of the upper bracket movement.

[0027] For example, refer to Figure 1 and Figure 2 As shown, a pawl 10 is connected to one end of the first connecting rod near the first moving wheel, and a rack 11 corresponding to the pawl is provided on the top surface of the lower bracket 6.

[0028] In this technical solution, during the upward movement of the upper support, the rack does not interfere with the movement of the pawl. However, in the event of a malfunction in the lifting device, the pawl engages between two corresponding teeth on the rack, preventing the scissor bracket from closing and thus preventing the furnace from falling suddenly, thereby improving safety. During the normal descent of the furnace, the pawl can be moved to disengage it from the rack surface.

[0029] For example, refer to Figure 1 and Figure 2 As shown, a circular guide rail 12 is provided at the top of the furnace 1, and the furnace casting pipe 2 is connected to the circular guide rail through an adjusting handle 13.

[0030] In this technical solution, the circular guide rail is an existing structure, and the adjustment handle is a cross-shaped structure, including handles that are movably connected to the circular guide rail via sliders. A through hole is provided at the junction of the handles to accommodate the furnace casting pipe. To improve the stability of the furnace casting pipe, locking bolts are provided on the side wall of the through hole. The angle of the furnace casting pipe can be adjusted by rotating the adjustment handle to adapt to the casting requirements of different positions.

[0031] In summary, this utility model has a simple structure and can realize the horizontal and vertical movement of the furnace. Combined with the 360° rotation adjustment of the furnace casting pipe, it meets the production requirements of the metal smelting and casting, and metal forming control industries.

[0033] The above description is only a specific embodiment of this application.
