Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to a cutting device for processing display brackets. Background Technology

[0002] In monitor stand manufacturing, the hollow rod is the core load-bearing component, and its ends require machining mounting holes to assemble the hinges or connectors. Traditional processing often employs a secondary drilling process, which suffers from problems such as fragmented processes, large positioning deviations, easy deformation of thin-walled tubing, and low processing efficiency, failing to meet mass production requirements. Processing the hollow rod of the monitor stand using laser tube cutting equipment offers significant advantages in non-contact processing and high efficiency, making it ideal for machining thin-walled tubing and precision holes.

[0003] However, the instantaneous high temperature of laser cutting is transmitted through the tube wall, causing localized overheating of the inner wall below the hole. This alters the metallographic structure, stress state, and surface condition of the material in this area, resulting in a decrease in material strength. When cutting a circular hole in this area, the thermal stress generated during cutting causes elliptical deformation of the cut edge, making it impossible to guarantee the roundness and dimensional accuracy of the hole, directly affecting subsequent shaft assembly. Current technologies often alleviate this localized overheating by reducing laser power and slowing down the cutting speed, but this leads to insufficient cutting penetration, resulting in incomplete cuts, severe slag buildup, and increased cut roughness, requiring secondary grinding and correction, which ultimately increases the number of processes and costs. Summary of the Invention

[0004] This invention provides a cutting device for processing display brackets, which includes a receiving block to catch high-temperature waste material falling during cutting, preventing the waste material from scratching the surface and causing localized overheating. The receiving block is equipped with two flow cooling chambers, through which flowing cold water can remove the heat generated during cutting, quickly reducing the temperature of the hollow rod, reducing deformation, and improving the cutting accuracy of the round hole. This invention solves the problem mentioned in the background art, which often alleviates the phenomenon of localized overheating of the inner wall by reducing laser power and slowing down the cutting speed. However, this leads to insufficient cutting penetration, resulting in problems such as incomplete cutting, severe slag buildup, and increased cut roughness, requiring secondary grinding and correction, which increases the number of processes and costs.

[0011] As an optional solution of the cutting equipment for processing the display bracket according to the present invention, the hollow top head is connected to the piston cylinder, and one end of the hollow top head is connected to a rotary joint. The rotary joint is connected to a variable frequency delivery pump through a pipe. The hollow top head is provided with a return water pipe, and the return water pipe is connected to the outlet of the two flow cooling chambers.

[0012] As an optional solution of the cutting equipment for processing the display bracket according to the present invention, wherein: a piston plate is slidably connected inside the piston cylinder, a piston guide rod is fixed on the piston plate, and the piston guide rod is elastically connected to the piston cylinder through a first spring.

[0013] As an optional solution of the cutting equipment for processing the display bracket according to the present invention, wherein: a plurality of symmetrically distributed fixed contact strips are provided in the receiving groove, a movable moving contact strip is provided on one side of the fixed contact strip, a T-shaped abutment bracket is connected to the moving contact strip, the T-shaped abutment bracket is slidably connected to the receiving block through a second spring, and an abutment ring is fixed on the piston guide rod.

[0014] As an optional solution of the cutting device for processing the display bracket according to the present invention, wherein: two movable arc-shaped scrapers are symmetrically arranged on one end of the receiving block, an abutment rod is fixed on the arc-shaped scraper, a sliding bracket is fixed on the receiving block, a guide block is fixed on the abutment rod, and the guide block is elastically connected to the sliding bracket through a third spring.

[0015] As an optional solution of the cutting equipment for processing the display bracket according to the present invention, wherein: the abutting rod is provided with an inclined abutting surface, the piston guide rod is fixed with two abutting heads, the abutting heads are slidably connected to the receiving block, and the abutting heads abut against the abutting surface.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the cutting equipment for processing the display bracket, the electric clamping chuck can clamp the hollow rod to be cut. Through the receiving block on the end of the hollow top installed on the tailstock, it can be inserted into the inside of the hollow part and moved to the direct below the cutting point. When the hollow top is cutting a hole, the receiving block can block the laser energy from acting on the lower tube wall to prevent the lower tube wall from changing the metallographic structure and reducing the material strength due to local overheating. This reduces the deformation of the cut edge in the area when cutting the round hole, thus ensuring the roundness and dimensional accuracy of the round hole.

[0018] The receiving groove on the receiving block is used to receive the high-temperature waste material falling from the cut, preventing the waste material from contacting the surface of the hollow rod to avoid scratching the surface and local overheating. It can further improve the protection of the uncut area. When adjusting the cutting angle after the processing of a single round hole in the hollow rod, the receiving block can move the waste material out of the hollow rod and deflect it with the cooperation of the third electric slide and the second servo motor, so that the opening of the receiving groove faces downward. The waste material is quickly discharged under the action of gravity, reducing the impact of heat on the hollow rod and facilitating heat dissipation after cutting.

[0019] 2. In the cutting equipment for processing the display bracket, the receiving block is equipped with two flow cooling chambers. The variable frequency delivery pump delivers cold water through the rotary joint, the hollow top head, and the piston cylinder in sequence into the two flow cooling chambers to absorb the heat generated during cutting. The water is then discharged through the return water pipe to form a circulation. The variable frequency delivery pump can change the water pressure, causing the water flow to fluctuate and form water flow disturbance, which can enhance the heat exchange capacity of the water flow, eliminate local heat accumulation, effectively improve the overall cooling and heat absorption effect, quickly reduce the temperature of the hollow rod, reduce deformation, and improve the cutting accuracy of the round hole.

[0020] The receiving groove is concave, with multiple surfaces in contact with cold water, which increases the surface area and improves the cooling effect. Several fixed and moving contact strips are set inside the receiving groove to contact the semi-molten waste material, which can prevent the waste material from directly adhering to the surface of the receiving groove and affecting the cleaning effect. When the water pressure in the piston cylinder changes, the water flow drives the piston plate, piston guide rod and contact ring to reciprocate, causing the contact ring to contact the T-shaped contact support, driving the moving contact strip to push the waste material to move in the receiving groove, preventing the waste material from sticking together and improving the discharge effect.

[0021] 3. In the cutting equipment for processing the monitor bracket, two movable arc-shaped scrapers are provided at one end of the receiving block. When cutting the round hole, the two arc-shaped scrapers abut against the upper inner wall and the lower inner wall of the hollow rod respectively. When the receiving block moves out of the hollow rod with the waste material, the two arc-shaped scrapers move synchronously to remove the welding slag around the round hole cutting point and the welding slag at the bottom of the hollow rod, thereby improving the quality of the hollow rod cutting.

[0022] When the water flow inside the piston cylinder pushes the piston plate to move initially, the two contact heads fixed on the piston guide rod can contact the contact surfaces of the two contact rods respectively, causing the two arc-shaped scrapers to move in opposite directions and press against the inner wall of the hollow rod, so that the welding slag can be cleaned out when the receiving block moves.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1, please refer to Figures 1 to 10 A cutting device for processing a display bracket includes a cutting table 1 and a laser cutting assembly 2. The laser cutting assembly 2 is installed on the cutting table 1 and includes a laser cutter 201. The laser cutter 201 performs hole cutting on the workpiece. The cutting table 1 is provided with a rotatable electric clamping chuck 3, a movable electric gripper 7 and a tailstock 4. A hollow top head 6 is rotatably connected to the tailstock 4.

[0036] The hollow top head 6 is used to move the workpiece on the electric gripper 7 to the electric clamping chuck 3. A receiving block 8 is fixed on the end of the hollow top head 6, and receiving grooves 9 are provided on both surfaces of the receiving block 8.

[0037] The laser cutting assembly 2 also includes a frame 202, which is fixed on the cutting table 1. A first electric slide 203 is fixed on the frame 202. A second electric slide 204 is fixed on the moving end of the first electric slide 203. The moving end of the second electric slide 204 is fixedly connected to the laser cutter 201 for adjusting the cutting height.

[0038] One end of the cutting table 1 is fixed with a first servo motor 10 that drives the electric clamping chuck 3 to rotate, and the other end of the cutting table 1 is fixed with a third electric slide 11 that drives the tailstock 4 to move. The tailstock 4 is fixed with a second servo motor 12 that drives the hollow top head 6 to rotate.

[0039] A servo cylinder 13 and a slide rail 14 are fixed on the cutting table 1. A mounting block 15 is fixed on the piston rod of the servo cylinder 13. One end of the mounting block 15 is slidably connected to the slide rail 14, and the other end of the mounting block 15 is fixedly connected to the electric gripper 7.

[0040] The receiving block 8 has two flow cooling chambers 16, and a piston cylinder 17 is fixed at one end of the receiving block 8. The piston cylinder 17 is connected to the two flow cooling chambers 16.

[0041] The hollow top head 6 is connected to the piston cylinder 17, and one end of the hollow top head 6 is connected to a rotary joint 35. The rotary joint 35 is connected to a variable frequency delivery pump 5 through a pipe. The hollow top head 6 is provided with a return water pipe 19, which is connected to the outlet of the two flow cooling chambers 16.

[0042] In this technical solution, reference is made to Figures 1 to 10The hollow rod to be cut is clamped on the electric gripper 7. The servo cylinder 13 on the cutting table 1 pushes the mounting block 15 to move along the slide rail 14, causing the electric gripper 7 to move to the cutting area, so that the centers of the hollow rod, the electric clamping chuck 3, and the hollow top head 6 are kept coaxial. The third electric slide 11 drives the tailstock 4 to move horizontally, causing the receiving block 8 at the end of the hollow top head 6 to insert into the hollow rod. At this time, the fingers of the electric gripper 7 open, and the hollow top head 6 moves horizontally along the clamping groove of the electric gripper 7, causing the hollow rod to move horizontally, thus cutting the hollow rod. One end of the rod is inserted into the electric clamping chuck 3 for clamping and positioning. Then the electric gripper 7 is reset. At the same time, the second servo motor 12 drives the hollow top head 6 to rotate through gear transmission, so that the receiving groove 9 on the receiving block 8 is kept horizontal and located directly below the opening of the hollow rod. Through the cooperation of the first electric slide 203 and the second electric slide 204, the cutting position and cutting height of the laser cutter 201 are adjusted. The laser cutter 201 first punctures the pre-drilled hole in the tube wall, and then, in cooperation with the electric clamping chuck 3, drives the hollow rod to rotate and move along a circular trajectory for circumferential cutting. During the cutting process, the receiving block 8 blocks the laser energy from acting on the tube wall below, reducing the deformation of the cut edge when cutting the circular hole, which can ensure the cutting size accuracy of the circular hole. At the same time, the high-temperature waste material from the cutting can fall directly into the receiving groove 9, avoiding scratching the surface of the hollow rod and local overheating of the area to be cut, thus improving the protection of the uncut area.

[0043] The hollow rod is made of aluminum alloy, which is lightweight, has reliable strength, is corrosion resistant and easy to process. During laser cutting, the inner wall of the hollow rod is easily affected by the high temperature of the laser and undergoes local deformation, which affects the processing quality. Therefore, it is necessary to cool down the cutting part of the hollow rod during cutting. In this application, the variable frequency pump 5 delivers cold water to the rotary joint 35 through the pipeline. The cold water flows into the piston cylinder 17 through the channel of the hollow top head 6, and then enters the two flow cooling chambers 16 of the receiving block 8 through the flow holes on both sides of the piston cylinder 17 to absorb the heat generated during the cutting process. The variable frequency pump 5 can change the water pressure to make the water flow alternately fluctuate to form pulse disturbance, enhance the heat exchange capacity, eliminate local heat accumulation, effectively improve the cooling and heat absorption effect, quickly reduce the temperature of the hollow rod, and reduce deformation. The receiving groove 9 is concave, which increases the contact surface with the cold water and promotes the increase of the heat exchange area, which can further improve the cooling effect. The molten welding slag and waste fall into the receiving block 8 and can be quickly cooled down, reducing the adhesion of the receiving block 8.

[0044] After one of the round holes on the hollow rod is cut, the receiving block 8 exits the hollow rod. On one hand, the second servo motor 12 drives the hollow top head 6 to rotate 180°, causing the opening of the receiving groove 9 for receiving waste to face downwards, so that the waste can be discharged in time. On the other hand, it leaves space for heat dissipation in the hollow rod so that residual heat can be dissipated. Then, the first servo motor 10 drives the electric clamping chuck 3 to rotate, causing the hollow rod to rotate 180° so that the other side can be cut with round holes. The receiving block 8 then extends into the hollow rod again to repeat the above process.

[0045] In this technical solution, the maximum forward and reverse angle of the second servo motor 12 is set to 180°. On the one hand, this facilitates the alternating use of the two receiving grooves 9 and improves the material discharge efficiency. On the other hand, the other end of the return water pipe 19 is located at the end of the hollow top head 6 and needs to be connected to the return water conveying pipe on the water tank. This can prevent the hollow top head 6 from bending and breaking due to excessive rotation angle.

[0046] The receiving block 8 is a symmetrically arranged V-shaped receiving block, so that both sides can be used to receive materials and absorb heat.

[0047] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 10 A piston plate 20 is slidably connected inside the piston cylinder 17, and a piston guide rod 21 is fixed on the piston plate 20. The piston guide rod 21 is elastically connected to the piston cylinder 17 through a first spring 22.

[0048] The receiving groove 9 is provided with several symmetrically distributed fixed contact strips 23. A movable contact strip 24 is provided on one side of the fixed contact strip 23. A T-shaped abutment bracket 25 is connected to the movable contact strip 24. The T-shaped abutment bracket 25 is slidably connected to the receiving block 8 through the second spring 26. An abutment ring 27 is fixed on the piston guide rod 21.

[0049] In this technical solution, reference is made to Figures 1 to 6When molten waste falls into the receiving groove 9 after cutting, it is prone to adhesion, leading to difficulties in discharge. The receiving groove 9 is equipped with several fixed contact strips 23 and moving contact strips 24 in a triangular shape, which can significantly reduce the contact area between the waste and the groove, reducing the risk of adhesion. When the cold water delivered by the variable frequency pump 5 enters the piston cylinder 17, it can push the piston plate 20 to move horizontally. On the one hand, during the movement, the flow hole on the piston cylinder 17 can be opened so that cold water can be injected into the flow cooling chamber 16. On the other hand, it causes the piston guide rod 21 to move initially on the receiving block 8, and the second spring 26 initially stores force. When the cold water pressure increases and forms a pulse fluctuation, the piston plate 20 is affected by the water pressure, pushing the piston cylinder 17 to reciprocate. This causes the contact ring 27 on the piston guide rod 21 to reciprocate against the end of the T-shaped contact bracket 25. The second spring 26 continuously stores and releases force so that the moving contact strip 24 can push the waste to move in the receiving groove 9, avoiding waste adhesion and improving the discharge effect.

[0050] Example 3 is an improvement upon Example 2. For details, please refer to [link / reference]. Figures 1 to 10 Two movable arc-shaped scrapers 28 are symmetrically arranged on one end of the receiving block 8. An abutment rod 29 is fixed on the arc-shaped scraper 28. A sliding bracket 30 is fixed on the receiving block 8. A guide block 31 is fixed on the abutment rod 29. The guide block 31 is elastically connected to the sliding bracket 30 through a third spring 32.

[0051] An inclined contact surface 33 is provided on the contact rod 29, and two contact heads 34 are fixed on the piston guide rod 21. The contact heads 34 are slidably connected to the receiving block 8, and the contact heads 34 abut against the contact surface 33.

[0052] In this technical solution, reference is made to Figures 2 to 9 The welding slag around the cut circular hole will affect the assembly quality. The welding slag that falls to the bottom of the hollow rod has a certain temperature. When the heat is dissipated, it will affect the cooling effect when another circular hole is cut. When the receiving block 8 is inserted into the hollow, the piston plate 20 is affected by the water pressure and drives the piston guide rod 21 to move initially. This causes the two contact heads 34 at the end of the piston guide rod 21 to contact the contact surfaces 33 of the two contact rods 29 respectively. This causes the guide blocks 31 on the two contact rods 29 to move in opposite directions on the sliding bracket 30, which drives the two arc-shaped scrapers 28 to open and press against the inner wall of the hollow rod. When the receiving block 8 is removed from the hollow rod, the welding slag on the inside can be automatically cleaned out.

[0053] Among them, the laser cutter 201, the first electric slide 203, the second electric slide 204, the electric clamping chuck 3, the frequency conversion pump 5, the electric gripper 7, the first servo motor 10, the third electric slide 11, the second servo motor 12, and the servo cylinder 13 are all electrically connected to the controller through wires. They are all existing technologies. The frequency conversion pump is a micro pulse frequency conversion water pump. By adjusting the pulse frequency, the water pressure fluctuates periodically between high and low.
