Description

Technical Field

[0001] This utility model belongs to the technical field of protective equipment for pipe laser cutting machines, and specifically relates to a protective device for pipe laser cutting machines. Background Technology

[0002] Protective devices for pipe laser cutting machines are crucial for ensuring the safety of operators, preventing laser radiation damage, and protecting the normal operation of the equipment.

[0003] Existing laser cutting machine protective devices typically include a cylindrical protective cover fixedly mounted on the laser cutting head of the cutting machine. During use, the operator moves the protective cover by moving the laser cutting head, thereby protecting against the splatter generated during cutting.

[0004] However, during use, because the protective cover is cylindrical and positioned above the laser cutting head, it can only protect against sparks that fly upwards from the laser cutting head during operation. It cannot eliminate sparks that fly downwards, and some sparks may even fly onto people, causing injury. In this case, workers have to wear protective clothing to protect themselves from the flying sparks. The above-mentioned technical solution requires workers to wear protective clothing, which is time-consuming and laborious and does not meet people's needs. Therefore, a protective device for pipe laser cutting machines is proposed. Utility Model Content

[0005] In view of this, this utility model addresses the shortcomings of the existing technology by providing a protective device for a tube laser cutting machine. It not only meets the basic requirement of protecting against sparks from the cutting process, but also allows for adjustment of the height of the protective cover through the cooperation between the moving mechanism and the protective cover, thereby preventing sparks from splashing onto people. This saves time and effort and meets people's usage needs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a protective device for a pipe laser cutting machine, including a base plate, a support plate on the left side of the base plate, a fixed plate on the right side of the left support plate, two guide rails on the fixed plate, a movable plate slidably mounted on the two guide rails, an mounting plate that moves back and forth on the movable plate, a laser cutting head at the bottom of the mounting plate, a support plate at the top of the mounting plate, a cylinder on the support plate, two baffles slidably mounted at the end of the output shaft of the cylinder, a fixed block on the right side of the movable plate, a right-opening groove in the middle of the fixed block, a slider inside the groove, and the slider being connected to the mounting plate.

[0007] As a further improvement of this utility model, a disc is provided on the right side of the support plate, and multiple clamps are provided on the disc. A rear side plate is provided on the rear side of the base plate, and a right side plate is provided on the right side of the base plate. A top plate is provided on the top of the rear side plate and the right side plate. A switch is provided on the right end of the right side plate, and the switch is electrically connected to the rotary motor. Support legs are provided at the four corners of the bottom of the base plate, and anti-slip pads are provided on the bottom of the four support legs. A crossbar is provided between two adjacent support legs.

[0008] As a further improvement of this utility model, a fixing rod is provided at the end of the cylinder output shaft. Slides are provided on the front and rear sides of the fixing rod, and slide bodies are provided inside the two slides. A double-acting screw is provided inside the two slides. The double-acting screw is screwed to the two slide bodies respectively. A rotary motor connected to the double-acting screw is provided on the rear side of the fixing rod. The rotary motor and the double-acting screw are connected by a coupling. The front slide body is connected to the front baffle, and the rear slide body is connected to the rear baffle.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, this design incorporates a cylinder. Activating the cylinder causes a fixed rod to move up and down, which in turn moves the baffle up and down, effectively shielding the sparks from different depths. Simultaneously, the operator activates a rotary motor, which in turn rotates a bidirectional lead screw. This rotation moves the sliding body inside the slide rail, causing the baffle to move back and forth. This allows the design to adapt to different pipe widths and protect against incoming sparks during cutting.

[0011] Secondly, this design includes a fixed plate with two guide rails that allow the laser cutting head to move up and down smoothly.

[0012] Thirdly, this design includes a movable plate with a fixed block. The fixed block has a sliding slider inside, which drives the laser cutting head to move back and forth, thus facilitating the cutting of pipes.

[0013] Fourth, this design incorporates multiple anti-slip pads, which effectively ensure the stability of the equipment during operation. Attached Figure Description

[0021] like Figure 1 , 2 As shown in Figure 3, a protective device for a pipe laser cutting machine includes a base plate 101, a support plate 102 on the left side of the base plate 101, a fixing plate 103 on the right side of the left support plate 102, two guide rails 104 on the fixing plate 103, a movable plate 105 slidably mounted on the two guide rails 104, a mounting plate 106 slidably mounted on the movable plate 105, a laser cutting head 118 at the bottom of the mounting plate 106, a support plate 107 at the top of the mounting plate 106, the support plate 107 being welded to the mounting plate, a cylinder 108 on the support plate 107, two baffles 109 slidably mounted at the end of the output shaft of the cylinder 108, a disc 119 on the right side of the support plate 102, and multiple clamps 120 on the disc 119.

[0022] like Figure 1 , 2As shown in Figure 4, a fixed rod 113 is provided at the end of the output shaft of the cylinder 108. Slide rails 114 are provided on the front and rear sides of the fixed rod 113 respectively. Slide bodies 116 are provided inside the two slide rails 114 respectively. A double-acting screw 115 is provided inside the two slide rails 114. The double-acting screw 115 is screwed to the two slide bodies 116 respectively. A rotary motor 117 connected to the double-acting screw 115 is provided on the rear side of the fixed rod 113. The rotary motor 117 and the double-acting screw 115 are connected by a coupling. The front slide body 116 is connected to the front baffle 109, and the rear slide body 116 is connected to the rear baffle 109.

[0023] like Figure 1 , 2 As shown, a fixing block 110 is provided on the right side of the movable plate 105. A sliding groove 111 with an opening facing right is provided in the middle of the fixing block 110. A slider 112 is provided inside the sliding groove 111. The slider 112 is connected to the mounting plate 106. A rear side plate 201 is provided on the rear side of the base plate 101. A right side plate 202 is provided on the right side of the base plate 101. A top plate 203 is provided on the top of the rear side plate 201 and the right side plate 202.

[0024] How to use this utility model:

[0025] When in use, the operator first turns on switch 204. Turning on switch 204 powers on rotary motor 117. The operator then places the pipe to be processed inside disc 119 and clamps the pipe with chuck 120.

[0026] At this point, the staff starts the laser cutting machine, causing the laser cutting head 118 to move and cut the pipe. The staff then adjusts the cylinder 108 according to the height of the pipe.

[0027] At the same time, the staff starts the rotary motor 117 according to the width of the pipe. The rotation of the rotary motor 117 drives the bidirectional lead screw 115 to rotate. The rotation of the bidirectional lead screw 115 drives the slide body 116 to move inside the slide rail 114. This causes the baffle 109 at the bottom of the slide body 116 to move back and forth, thus providing good protection for the cutting points of pipes of different widths.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
