Description

Technical Field

[0001] The invention relates to the technical field of metal cutting, in particular to a flame cutting device with a multi-point synchronous cutting function. Background Art

[0002] Flame cutting is a common method for rough processing of steel plates. Flame cutting is gas cutting. Traditionally, acetylene and propane are used for cutting. Later, people used natural gas as fuel for cutting. The gas flame is used to heat the surface of the steel plate to make it reach the combustion temperature locally, and then a high-purity, high-speed cutting oxygen flow is introduced to cause the metal to undergo a violent combustion reaction and release heat. At the same time, the huge kinetic energy of the high-speed cutting oxygen flow is used to blow away the combustion products and form a cutting seam. Flame cutting has made outstanding contributions to the development of the cutting industry, cutting technology and promotion and application.

[0003] However, the danger of flame cutting and subsequent processing are both thorny issues. Usually, the workpieces processed by flame cutting require pre-processing or subsequent processing, so the processing methods are usually rough. In the production process, there are usually some problems such as explosion and serious deformation of the workpiece. These problems need to be solved urgently. If they are not solved, it will not only cause personal safety problems for operators, but also blind processing will cause damage to the workpiece. Subsequent processing will not only waste time, but also cause a lot of labor and material waste. Summary of the invention

[0004] The object of the present invention is to provide a flame cutting device with a multi-point synchronous cutting function to solve the problems raised in the above background technology.

The frame is electrically connected. When cutting, you first need to install the workpiece on the compensation mounting seat, and then start the cutting gun. The cutting gun sprays a high-pressure flame. The gas conduit and the oxygen supply conduit work together to provide combustion gas to the cutting gun to ensure long-term cutting operation. In the cutting process, as the composite frame moves, the workpiece will also move. The multi-point positioning frame can adjust the posture and position of the cutting gun to achieve synchronous multi-point cutting operations. When cutting, the wind gathering ring on the follower frame will change with the changes of the cutting gun, thereby extending the flame length and flame depth. All these operating instructions are issued by the control box, and the control box balances the coordination relationship between various components.

[0007] A moving motor and a moving groove are provided on the compound frame, a supporting guide rail is provided on the cutting mounting frame, a moving motor is provided in the moving groove, a moving gear is provided on the output end of the moving motor, teeth are provided on the supporting guide rail, the moving gear meshes with the teeth on the supporting guide rail, a plurality of mounting grooves are provided on the compound frame, each compensating mounting frame is respectively provided in a corresponding mounting groove, the mounting groove and the compensating mounting frame are detachably connected, when cutting is required, the moving motor will drive the moving gear to rotate, and the rotation of the moving gear drives the moving groove to move on the supporting guide rail, and the compensating mounting frame is responsible for installing the workpiece to be cut, and the cutting trajectory is controlled by controlling the progress of the moving motor, and the mounting groove supports the position of the compensating mounting frame to adapt to workpieces of various shapes.

Before cutting, the workpiece needs to be installed on the clamping frame. At this time, the fastening clamp and the capturing clamp are opened, the workpiece falls on the fastening clamp, and then the capturing clamp is rotated onto the workpiece, and then the locking key is released. The locking key will lock the fastening clamp, thereby locking the workpiece firmly. When it is necessary to cut a large workpiece, a leapfrog installation method can be adopted to lock and capture the workpiece, thereby increasing the processing range of the workpiece.

[0009] A plurality of compensation grooves are respectively arranged on the capture clamp and the fastening clamp, and a compensation wheel and a compensation spring are respectively arranged in each compensation groove, and each compensation wheel is respectively slidably connected with the corresponding compensation groove, and a pressing inclined groove is arranged on the compensation wheel, and the compensation spring is pressed against the corresponding pressing inclined groove, and a bearing is arranged on the supporting end of the compensation wheel.

During the workpiece installation process, the electric shaft is controlled by the control box, and the capture clamp and the fastening clamp will clamp the workpiece, and the compensation wheel will press against the workpiece, and make the compensation spring press against the compensation wheel, so that the compensation wheel no longer rotates. In order to avoid accidentally damaging the capture clamp and the tendon and bone piece during the cutting process, the connection shaft can be controlled to rotate by the control box during cutting, and the workpiece can be easily pushed at this time without causing the workpiece to be excessively offset.

When the permeability of the regulating valve increases, the oxygen spraying amount at this time increases. , the length of the oxygen jet also increases, which is coordinated with the expansion of the first diffuser and the second diffuser. When the permeability of the regulating valve decreases, the oxygen ejection volume at this time decreases, and the length of the oxygen jet also decreases, which is coordinated with the first diffuser and the second diffuser when they are close to each other. Through the cooperation of the wind-sensing spring and the return air switch, the current cutting depth and cutting force can be known. When the trigger frequency of the return air switch increases, the control box will control the regulating valve to reduce the air volume to avoid the increase of oxygen volume or excessive wind and waves, which will cause the workpiece to appear concave and deformed.

When it contacts the workpiece, the heat wave hitting the workpiece will rebound to the feedback net, and the feedback box on the feedback net will feel the feedback degree of its heat wave, which is fed back by the feedback diaphragm and the deformation is applied to the feedback spring. When the heat wave is too large, the force of the feedback spring acting on the feedback switch increases, so the feedback switch is triggered. When cutting, preheating is required first. After the preheating is completed, the first diffuser and the second diffuser are adjusted by the power-on information fed back, and the flame width is reduced to perform deep cutting. After cutting through, the power-on information transmitted from the feedback diaphragm becomes less.
