Description
Technical Field
[0001] This utility model relates to the technical field of double-headed flame cutting devices, specifically a deformation-resistant steel structure double-headed flame cutting device. Background Technology
[0002] A dual-burner flame cutting device is a piece of equipment used for cutting metal materials. It consists of two torches, each with an independent gas channel and nozzle, allowing for adjustment of the flame size and shape to suit different cutting needs. However, existing dual-burner flame cutting devices have some shortcomings, such as:
[0003] The flame cutting device for steel plates described in application number CN202421421861.2 has a certain safety protection function, but it has obvious design flaws. In actual use, the device is not equipped with an anti-deformation mechanism. During the flame cutting process, the steel will rapidly heat up due to local high temperature and then cool down rapidly. Under the influence of the thermal expansion and contraction characteristics of metal materials, large thermal stress will be generated inside the steel. These thermal stresses cannot be effectively released, which can easily lead to deformation such as twisting and warping of the steel. Once the steel is deformed, the cutting accuracy is difficult to guarantee, and the size of the cut workpiece will deviate from the design size. Subsequent processing such as welding and assembly will face great difficulties. This will not only increase processing costs and extend the processing cycle, but may also affect the quality and performance of the entire product, reducing production efficiency and economic benefits.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] Please see Figures 1-12 The present invention provides a double-headed flame cutting device for a deformation-resistant steel structure, embodiment one.
[0039] For details, please refer to the following: Figures 1-8 It includes a housing 1, a first motor 2, a guide rod 3, a bearing slider 4, a drive screw 5, a bearing frame 6, a bearing partition 7, a first clamp 8, a cutting spray gun 9, an air inlet 10, a hopper 11, a reciprocating screw 12, a first bearing rod 13, a second bearing rod 14, a turbo fan 15, a ventilation slot 16, a fixing frame 17, a reciprocating slider 18, a second motor 19, a second clamp 20, a guide slider 21, and a pin 22;
[0040] The top of the housing 1 is equipped with a cutting drive mechanism, which consists of a guide rod 3, a bearing slider 4, a drive screw 5 and a support frame 6. The motor installed on the support frame 6 provides power to the drive screw 5, enabling it to rotate. When the drive screw 5 rotates, the bearing slider 4, which is threaded to it, will move freely left and right under the restriction of the guide rod 3. This design lays the foundation for the left and right cutting motion of the subsequent cutting spray gun 9.
[0041] Meanwhile, the box 1 is equipped with a heat dissipation mechanism, which mainly includes a first motor 2, an air inlet 10, a turbo fan 15, and a support partition 7. The first motor 2 provides power to the turbo fan 15. When the turbo fan 15 rotates at high speed, air is drawn into the box 1 through the air inlet 10. The air then flows through the support partition 7 and comes into uniform contact with the cutting workpiece, thereby achieving uniform heat dissipation. This is crucial for reducing the deformation of the steel structure caused by heat during the cutting process.
[0042] In terms of heat dissipation, the first motor 2 is fixedly connected to the left side of the housing 1, and its output shaft is fixedly connected to the turbo fan 15. An air inlet 10 is opened on the right side of the housing 1, and the internal air duct of the housing 1 is designed as a U-shaped structure. In this way, when the first motor 2 drives the turbo fan 15 to rotate at high speed, air is drawn in from the air inlet 10, passes through the U-shaped air duct, and then flows through the bearing partition 7, which can make more full and uniform contact with the cutting workpiece, thereby achieving efficient and uniform heat dissipation and effectively reducing the deformation of the steel structure caused by heat during the cutting process.
[0043] For the treatment of waste materials and auxiliary cooling water, a hopper 11 is installed at the bottom of the box 1 using a sliding connection. The hopper 11 is divided into two parts: the left part is a waste bin for collecting waste materials generated during cutting; the right part is a water bin. A pin 22 is slidably connected to the box 1. The pin 22 engages with the opening on the upper surface of the hopper 11 to control the opening and closing of the water bin. A load-bearing partition 7 is fixedly connected to the side of the box 1. The load-bearing partition 7 is designed as a grid structure, and ventilation slots 16 are opened on its surface. This grid structure and ventilation slots 16 allow air to contact the cutting parts more evenly, further enhancing the heat dissipation effect.
[0044] Regarding the optimization of the cutting drive mechanism, a support frame 6 is fixedly connected above the housing 1, a pair of guide rods 3 are clamped between the support frames 6, and a support slider 4 is mounted on the guide rods 3. The center line of the support slider 4 is threadedly connected to the drive screw 5, which is driven by the motor built into the support frame 6. It is worth mentioning that the support slider 4 is designed as a trapezoidal structure, which can significantly improve the stability of the support slider 4 during movement. A fixing frame 17 is fixedly connected above the support slider 4 to provide stable support for the installation of subsequent components.
[0045] In the motion control of the cutting spray gun 9, a second motor 19 is fixedly connected to the side of the fixed frame 17. The output shaft of the second motor 19 is fixedly connected to the reciprocating lead screw 12. A guide slider 21 is slidably connected below the reciprocating lead screw 12. The guide slider 21 is rotatably connected to the reciprocating slider 18. A first bearing rod 13 is rotatably connected above the reciprocating slider 18. A second clamp 20 is mounted on the top of the first bearing rod 13. A second bearing rod 14 is mounted on the side of the second clamp 20. A pair of first clamps 8 and the cutting spray gun 9 are parallelly distributed on the left side of the second bearing rod 14. The reciprocating motion of the cutting spray gun 9 can be realized by driving the reciprocating lead screw 12 through the second motor 19. This reciprocating motion, in conjunction with the left and right movement function of the cutting spray gun 9 mentioned above, can complete the all-round cutting of the steel structure, greatly improving the flexibility and accuracy of cutting.
[0046] Example 2
[0047] For details, please refer to the following: Figures 9-11 The difference between this embodiment and the first embodiment is that the side of the pin 22 is fixedly connected to the sponge tube 23, the sponge tube 23 is made of high-strength plastic pipe, and the inside of the sponge tube 23 is filled with high-density sponge. Five atomizers 24 are evenly fixed at the bottom of the sponge tube 23.
[0048] Five atomizers 24 are evenly fixed at the bottom of the sponge tube 23. When the pin 22 is inserted, the water in the water tank is atomized by the atomizers 24 through the sponge tube 23 and sprayed on the cutting area to further assist in heat dissipation and dust reduction.
[0049] Example 3
[0050] For details, please refer to the following: Figure 12 The difference between this embodiment and embodiment one is that: the transducer 26 is fixedly connected to the center line of the side of the housing 1, and four foot pads 25 are evenly fixed to the bottom of the housing 1. The foot pads 25 are made of rubber.
[0051] A transducer 26 is fixedly connected to the center line of the side of the housing 1. The transducer 26 converts electrical energy into ultrasonic vibration energy. During the cutting process, the ultrasonic vibration energy helps to reduce cutting resistance, improve cutting efficiency, and reduce the heat generated during cutting, thus reducing the possibility of steel structure deformation. Four rubber feet 25 are evenly fixed to the bottom surface of the housing 1 to provide shock absorption and anti-slip properties, ensuring the stability of the equipment during operation.
