Technical Field

[0001] The invention relates to the technical field of metal steel cutting, in particular to a metal steel rapid cutting device. Background Art

[0002] Metal steel is a material of a certain shape, size and performance made from steel ingots, billets or steel through pressure processing. It is mainly used in the construction, manufacturing, aerospace and other fields. Square steel pipe (hereinafter referred to as steel pipe) is a kind of metal steel. Steel pipe is widely used due to its high strength, light weight and easy processing. When in use, it is usually composed of multiple long steel pipes and short steel pipes welded or otherwise spliced ​​into a stable frame to form a stable support structure to provide a working platform or support heavy objects. The joints of the steel pipes are usually cut into bevels to increase the contact area of ​​the steel pipe joints and increase the stability of the overall structure.

[0003] When cutting a steel pipe, the steel pipe is usually continuously fed into the clamping device through a feeding device, and then the clamping device is controlled to drive the steel pipe to move to the corresponding position of the cutting device, and then the cutting device is controlled to cut the steel pipe according to the cutting angle of the steel pipe, and finally the steel pipe after cutting is taken out, thereby realizing continuous and rapid cutting of the steel pipe.

[0004] At present, the following problems exist when cutting steel pipes: 1. When cutting steel pipes, since the steel pipes of the same specification are cut in batches, it is easy to cause the problem that the long steel pipes and the short steel pipes cut in batches are difficult to accurately splice at the cutting points, resulting in the cutting angles of the batch steel pipes not meeting the requirements, reducing the stability of the steel pipe composition frame, and thus affecting the subsequent use quality of the steel pipe; 2.

At the same time, the present invention can also grind the cut parts of the steel pipes to increase the cutting efficiency of the steel pipes. Specifically, firstly, the long steel pipes and the short steel pipes are stacked and placed in the feeding device 3 respectively, and then the feeding device 3 is controlled to alternately feed the long steel pipes and the short steel pipes into the positioning device 5, and the positioning device 5 can arrange the steel pipes in the center left and right, then the positioning device 5 is controlled to feed the steel pipes in the center into the conveying device 2, and the conveying device 2 is controlled to clamp and fix the steel pipes in the center, and finally the conveying device 2 is controlled to drive the left and right ends of the steel pipe to move rightward in turn to the corresponding positions of the cutting device 4, so that the cutting device 4 cuts the steel pipe.

[0034] When the steel pipe is cut, the grinding device 6 is controlled to grind the cut ends of the left and right ends of the steel pipe, and then the conveying device 2 is controlled to loosen the steel pipe, and the steel pipe after cutting is taken out manually, and the feeding device 3 feeds the long steel pipe and the short steel pipe alternately to ensure that the cut ends of the long steel pipe and the short steel pipe can be accurately spliced.

[0035] See also Figure 1 , Figure 3-Figure 5 The feeding device 3 includes a material storage barrel 31 distributed on the left side above the base 1, and the front and rear ends of the material storage barrel 31 are fixedly connected to the base 1 through a plurality of L-shaped fixing rods 35, and the lower end of the material storage barrel 31 is provided with two square holes 36 arranged symmetrically front and back, and a partition 32 is fixedly installed in the middle of the left and right inner walls of the material storage barrel 31, and the opposite sides of the partition 32 and the front and rear inner walls of the material storage barrel 31 are installed with a pushing unit 33 for conveying a steel pipe into the square hole 36, and the lower end of the material storage barrel 31 is installed with a matching unit 34 for making the two pushing units 33 alternately convey their corresponding steel pipes; the middle parts of the front and rear inner walls of the material storage barrel 31 are both slidably installed with a limit block 311, and an adjusting member 312 is commonly installed between the limit block 311 and the material storage barrel 31, and the middle parts of the front and rear ends of the partition 32 are both installed with a push plate 322 through a No. 1 multi-stage push rod 321, and the lower end of the push plate 322 is slidably connected to the lower inner wall of the material storage barrel 31.

[0036] It should be noted that the adjustment member 312 in the present invention specifically adopts an adjusting screw to adjust the position of the limit block 311, wherein the adjusting screw is connected to the limit block 311 by threaded cooperation, and the adjusting screw is rotatably connected to the storage barrel 31, and the upper and lower position adjustment of the limit block 311 is achieved by screwing the adjusting screw.

[0037] The feeding device 3 is used to alternately feed the long steel pipes and the short steel pipes; specifically, firstly, the position of the limit block 311 is adjusted according to the height control adjustment member 312 of the steel pipe, so that the distance between the lower end of the limit block 311 and the lower inner wall of the storage barrel 31 corresponds to the height of a single steel pipe, and then the long steel pipe and the short steel pipe are stacked with the cutting surface facing upward and placed in the two spaces of the storage barrel 31 separated by the partition 32, and the matching unit 34 is controlled to drive the two pushing units 33 to push the corresponding steel pipes alternately, so that the pushing unit 33 pushes the steel pipe located at the bottom layer and away from the partition 32 in the direction away from the partition 32 until it reaches In the corresponding square hole 36, alternating loading of long steel pipes and short steel pipes is realized, and the limit block 311 can block the steel pipe above the pushed steel pipe to prevent the pushed steel pipe from driving the steel pipe above it to move into the square hole 36 under the action of friction. At the same time, by periodically controlling the No. 1 multi-stage push rod 321, the corresponding push plate 322 is driven to move away from the partition 32, so that the push plate 322 pushes all steel pipes in the direction away from the partition 32, ensuring that the steel pipe on the side away from the partition 32 can correspond to the position of the limit block 311, thereby ensuring that the pushing unit 33 can continuously transport the steel pipe into the square hole 36.

[0038] See also Figure 4-Figure 6 The pushing unit 33 includes two symmetrically arranged square plates 331 slidably installed between the partition 32 and the opposite sides of the storage barrel 31. The opposite sides of the two square plates 331 are installed with squeezing plates 333 through multiple connecting springs 332, and the squeezing plates 333 are also slidably installed between the opposite sides of the partition 32 and the storage barrel 31. The opposite sides of the two squeezing plates 333 and the lower sides of the ends away from the partition 32 are slidably installed with square rods 335 through return springs 334. The opposite sides of the two square rods 335 slide forward and backward to penetrate the corresponding squeezing plates 333, and the opposite sides of the two square rods 335 are slidably installed with material removing plates 336.

[0039] See also Figure 4-Figure 7A toggle plate 337 is fixedly installed on the opposite sides of the two square plates 331 and corresponding to the positions of the square rods 335. The side of the toggle plate 337 close to the square rods 335 is set as an inclined surface for driving the square rods 335 to move away from the partition 32. Separation columns 338 are fixedly installed on the opposite sides of the upper ends of the two toggle plates 336. The upper ends of the separation columns 338 slide left and right and penetrate the square rods 335. Fixed plates 339 are fixedly installed at the positions corresponding to the separation columns 338 on the extrusion plate 333, and the separation columns 338 are slidably installed in the preset inclined grooves on the fixed plates 339. The inclined grooves of the fixed plates 339 are used to drive the two separation columns 338 to move left and right.

[0040] See also Figure 3 , Figure 6 and Figure 8 A round rod 330 is fixedly installed at the lower end of the square plate 331, and the lower end of the round rod 330 slides left and right through the lower end of the storage barrel 31 through a guide spring 3301. The matching unit 34 includes a transmission rod 341 slidably installed in the middle of the lower end of the storage barrel 31, and a reciprocating member 342 is connected between the transmission rod 341 and the lower end of the storage barrel 31. Two left-right symmetrically arranged matching blocks 343 are fixedly installed at both front and rear ends of the transmission rod 341, and the opposite sides of the two left-right symmetrical matching blocks 343 and one end away from the transmission rod 341 are set to an inclined surface, and the inclined surface of the matching block 343 is used to drive the two left-right arranged round rods 330 to move in a direction close to each other.

[0041] It should be noted that the reciprocating member 342 in the present invention includes a threaded rod, which is connected to the transmission rod 341 by threaded cooperation. The front end of the threaded rod is rotatably connected to a fixed block fixedly installed at the lower end of the material storage barrel 31, and the rear end of the threaded rod is connected to the output shaft of motor No. 1 fixedly installed at the lower end of the material storage barrel 31. By controlling motor No. 1 to drive the threaded rod to rotate reciprocally, the transmission rod 341 can be reciprocated back and forth.

[0042] The pushing unit 33 is used to convey a steel pipe into the square hole 36, and the matching unit 34 is used to make the two pushing units 33 alternately convey the corresponding steel pipe; specifically, the control reciprocating member 342 drives the transmission rod 341 to move forward and backward. When the transmission rod 341 moves forward, the transmission rod 341 drives the two square plates 331 located at the front side to move in a direction close to each other through the two matching blocks 343 on the front side and the corresponding round rod 330. The two square plates 331 located at the front side drive the two corresponding extrusion plates 333 to move in a direction close to each other through the connecting spring 332. When the pressing plate 333 is attached to the front and rear sides of the steel pipe, the material removal plate 336 is inserted into the steel pipe located at the bottom layer and away from the side of the partition 32, and the connecting spring 332 is compressed at the same time, so that the two square plates 331 move towards each other relative to the extrusion plate 333, so that the inclined surface of the toggle plate 337 drives the square rod 335 to move away from the partition 32 and compress the reset spring 334, so that the square rod 335 drives its corresponding material removal plate 336 to move away from the partition 32, and the material removal plate 336 drives the corresponding steel pipe to move away from the partition 32 to above the square hole 36.

[0043] When the square rod 335 drives the material-shifting plate 336 to move away from the partition plate 32, the two material-shifting plates 336 located on the front side move away from each other under the action of the inclined grooves of the separation column 338 and the fixing plate 339, so that the material-shifting plates 336 gradually move out of the steel pipe. When the steel pipe is completely located above the square hole 36, the steel pipe falls horizontally into the square hole 36 with the cutting surface facing upward under the action of gravity. When the reciprocating member 342 drives the transmission rod 341 to return to its initial position, the round rod 342 Under the action of the guide spring 3301, 330 drives the square plate 331 to return to the initial position. At the same time, the extrusion plate 333 returns to the initial position under the action of the connecting spring 332, and the square rod 335 drives the material removal plate 336 to return to the initial position under the action of the reset spring 334. Similarly, when the transmission rod 341 moves backward, the two material removal plates 336 located on the rear side can move their corresponding steel pipes into the corresponding square holes 36, thereby realizing the alternating feeding of long steel pipes and short steel pipes.

[0044] See also Figure 1 , Figure 3 and Fig. 9 The positioning device 5 includes a connecting tube 51 fixedly installed at the lower end of the storage tube 31, a feeding port is opened in the middle of the lower end of the connecting tube 51, and two active units 53 arranged symmetrically in front and back are installed on the lower inner wall of the connecting tube 51.

Two left-right symmetrically arranged positioning blocks 52 are installed in the middle of the lower inner wall of the connecting tube 51 for sliding left and right through multiple tightening springs 54, and the opposite sides of the two positioning blocks 52 are set to trapezoidal structures.

[0045] The positioning device 5 is used to arrange the steel pipe in the center left and right to ensure accurate cutting of the steel pipe; specifically, when the steel pipe falls downward from the square hole 36, the steel pipe can fall into the connecting tube 51, and then the two active units 53 are controlled to push the steel pipe in the direction of approaching each other, so that the active unit 53 corresponding to the steel pipe can push the steel pipe to the middle of the connecting tube 51, and when the steel pipe moves to the corresponding position of the positioning block 52, the steel pipe can cooperate with the trapezoidal structure of the two positioning blocks 52 to drive the two positioning blocks 52 to move in the direction away from each other, and under the action of the tightening spring 54, the positioning block 52 can arrange the steel pipe in the center left and right, and when the steel pipe moves to the middle of the connecting tube 51, the two active units 53 can be pressed against the front and rear sides of the steel pipe, so that the steel pipe can be arranged horizontally left and right, and the middle of the steel pipe is aligned with the middle of the connecting tube 51.

When the steel pipe moves to the middle of the connecting tube 51, the top spring rod 533 is compressed, so that the steel pipe can be arranged horizontally left and right. When the No. 2 multi-stage push rod 532 is controlled to drive the active plate 531 to return to the initial position, the active plate 531 can cooperate with the inclined surface of the L-shaped rod 521 to drive the two positioning blocks 52 to move away from each other, thereby separating the positioning blocks 52 and the steel pipe, so that the steel pipe can fall horizontally downward from the loading port of the connecting tube 51.
