Description

Technical Field

[0001] The invention relates to a direct-feeding semi-automatic feeding mechanical device. Background Art

[0002] Among the existing metal laser cutting equipment, the fully automatic loading and unloading pipe cutting machine is an automated pipe cutting equipment that has quietly emerged in recent years. It can independently complete the loading and unloading of pipes without the need for manual placement. The existing pipe cutting machine has a bed structure that can be roughly divided into two categories, one is a gantry structure, and the other is a wall-mounted structure. The chuck of the existing gantry machine tool pipe cutting machine is located at the center of the guide rail, so the operation is relatively stable. However, it is difficult to achieve zero tail material, and the material waste is huge. The loading logic actions are more and time-consuming, so the failure rate is relatively high. Due to the excessive displacement action, it is easy to cause scratches on the surface of the material and the pipe.

[0003] The loading device is a key equipment on the production line. The current laser cutting equipment adopts the traditional manual loading and unloading method or semi-automatic feeding, which requires manual intervention, high labor intensity, low production efficiency and poor working environment. On the other hand, some pipes are large and heavy, and operators are easily injured if they do not operate them properly during transportation, which causes safety concerns. However, when the pipe is transported to the bracket by the conveying device, it will be tilted and scattered, and the axis of the pipe cannot coincide with the line connecting the center of the front chuck and the rear chuck, which is not conducive to the clamping of the pipe. This is the shortcoming of the existing technology.

[0004] Most of the semi-automatic feeders currently used have a slow feeding speed, resulting in a long feeding cycle, which will affect the working efficiency of the cutting machine.

[0005] When the pipe cutting machine is cutting the pipe, it will generate pressure on the workpiece. If the pipe is long, it may cause the pipe to deform, which will reduce the cutting accuracy and cause waste. Therefore, when cutting, the pipe needs to be supported and limited, which can prevent the pipe from deforming and "deviation" when cutting.

[0006] When the pipe is transported to the bracket by the conveying device, after being cut and processed, the pipe at the rear needs to be pushed forward to continue the cutting work. Summary of the invention

The bed mechanism of the device includes the bed body 1 and the bed appendage 10 located on the side, which has an "L" shape from the cross-section. The claw 21 on the chuck 2 is located above the bed appendage 10, so that the waste chips generated by the cutting will not fall on the track 12 on the bed body 1. The loader 3 and the floating support 11 can be installed on the bed appendage 10 part. Thereby, the floating support 11 is used to cooperate with the loader 3 to transport the pipe.

[0036] At least one track 12 is arranged on the bed body 1 , and a plurality of support seats 22 are arranged at the bottom of the chuck 2 . The support seats 22 move on the track 12 , and claws 21 are arranged on the front and rear sides of the chuck 2 .

[0038] The floating support assembly 3 includes a vertically arranged support mounting plate 31, a support cylinder 32 and a support arm 33. The tail ends of the support cylinder 32 and the support arm 33 are rotatably arranged on the support mounting plate 31. The support cylinder 32 is provided with a support rod 321 that can be extended and retracted. The top end of the support rod 321 is rotatably connected to the support arm 33. The support cylinder 32 drives the support rod 321 to extend and retract, thereby supporting the lifting and lowering of the support arm 33. The floating support assembly 3 is used to lift and lower the pipe. A plurality of floating support placement ports 102 are arranged at intervals on the bed appendage 10. The floating support assembly 3 is arranged in the floating support placement port 102. The floating support assembly 3 can move up and down so as to move the pipe transported by the feeder 73 upward for clamping by the claws 21 on the chuck 2.

[0039] The support mounting plate 31 is provided with a first mounting seat 34, on which an auxiliary arm 35 is rotatably provided, a second mounting seat 43 and a third mounting seat 44 are provided on the back of the clamping portion mounting plate, and the top end of the auxiliary arm is rotatably provided on the third mounting seat 44; the top end of the support arm is rotatably provided on the second mounting seat 43; the spacing between the second mounting seat 43 and the third mounting seat 44 is equal to the distance from the first mounting seat 34 to the rotation axis of the rear end of the support arm 33; the support arm 33 and the auxiliary arm 35 form two parallel sides of a parallelogram, and the support mounting plate 31 and the clamping portion mounting plate 4 form another pair of parallel sides of the parallelogram. Therefore, when the support arm 33 drives the clamping portion mounting plate 4 to move up and down, it can ensure that the clamping portion mounting plate 4 is parallel to the support mounting plate 31, that is, it maintains a vertical state.

[0040] The floating support assembly 3 is arranged in a row and connected to the feeding assembly 11; the feeding assembly 11 includes a mounting plate 110, a movable plate 13 and a slide rod 14, the movable plate 13 is arranged on the mounting plate 110 and moves along the first slide rail 111, and the limit plate 141 is arranged on the slide rod 14; the movable plate 13 is provided with a push rod 131, and the push rod 131 pushes the slide rod 14 to move so as to drive the limit plate 141 to move; the feeding assembly 11 is provided with a plurality of limit plates 141 and drives the movement of the limit plates 141; the floating support assembly 3 is provided with a limit shaft 331, and the limit shaft 331 cooperates with the limit plate 141 to work to limit the lifting angle of the support arm 33. A limit shaft mounting plate 332 is provided at the lower part of the support arm 33, and the limit shaft 331 is detachably or fixedly provided on the limit shaft mounting plate 332; the limit plate 141 is a triangle, and its hypotenuse is provided downward, and the hypotenuse is used to limit the upward movement of the limit shaft 331; after the limit plate 141 is moved, the distance that the limit shaft 331 can move upward is changed. The mounting plate 1 is provided with a driving motor 12, and the driving motor 12 drives the gear to rotate. The moving plate 2 is provided with a rack, and the rack is meshed and connected with the gear shown to cooperate with the transmission. The device uses the support mounting plate 31, the support cylinder 32 and the support arm 33 to form a stable triangle, and the support cylinder 32 can push the support rod 321 to extend and retract, so that the triangle changes shape, thereby realizing the support arm 33 to go up and down. Multiple floating support assemblies 3 are carried out synchronously, so that the steel pipe can be lifted and moved down stably. The function of the feeding assembly 11 is to limit the maximum angle of the support arm 33 to go up, so as to control the highest moving position of the pipe. The limiting function mainly relies on the limiting shaft 331 and the limiting plate 141. The limiting plate 141 is triangular, and by moving the limiting plate 141, the lifting amount of the limiting shaft 331 can be changed. The device uses the driving motor 112 to drive the moving plate 13 to move, and the moving plate 13 drives the push rod 131 to move together. After the push rod 1321 moves, it can drive the slide bar 14 to move, so that the limiting plate 141 is passively moved, thereby changing the maximum lifting amount that the limiting shaft 331 can rise.

[0041] A clamping assembly for clamping the steel pipe is arranged at the top end of the support arm 33, and the clamping assembly includes a clamping part mounting plate 4, and the clamping part mounting plate 4 is provided with a clamping cylinder 5, a bottom clamping part 42 and two side clamping parts 41. The two side clamping parts 41 are driven by the clamping cylinder 5 to move synchronously towards each other, thereby cooperating with the bottom clamping part 42 to perform a centering clamping effect on the pipe.

[0042] The front side of the clamping part mounting plate 4 is rotatably provided with a parallel first swing arm 51 and a second swing arm 52. The top ends of the first swing arm 51 and the second swing arm 52 are provided with a connecting arm 411. The connecting arm 411 is provided with a side clamping part 41. The second swing arm 52 is connected with a driving arm 53. The driving arm 53 is driven by the clamping cylinder 5 to extend and retract. The back side of the clamping part mounting plate is provided with the same mechanism and parts as the front side. The clamping part mounting plate is provided with a gear bin 45. Two meshing synchronous gears 451 are provided in the gear bin 45. The rotating shafts of the two synchronous gears 451 are respectively connected to one of the two second swing arms 52. The synchronous gears 451 cooperate with the transmission to make the two second swing arms 52 swing synchronously. The two clamping cylinders can drive at the same time or select one to drive. The bottom clamping part and the side clamping part are provided with rollers, and the outer wall of the rollers is provided with a friction layer. The automatic centering function of this device is to use the meshing synchronous gear 451 to make the two second swing arms 52 swing synchronously. In this way, the movement of the two side clamping parts 41 can be carried out synchronously, and the movement amount is exactly the same. By configuring multiple devices on the production line, adjusting each position to ensure the connection line between the center of the front chuck and the rear chuck, and then controlling the cylinder to move synchronously, the movement of the two side clamping parts 41 at each location can be carried out synchronously to achieve the centering function. Therefore, the two clamping cylinders 5 can work at the same time, or one can work while the other rests, and then change jobs. Rollers are provided on the bottom clamping part 42 and the side clamping part 41, and a friction layer is provided on the outer wall of the roller. The friction layer can provide protection on the contact surface when clamping the steel pipe to avoid damage to the surface of the steel pipe.

The vertical pushing plate 621 rests on the tail end of the pipe, and the pushing head 613 is connected to the vertical pushing plate 621.

The bed attachment 10 can be connected to the bed body in various forms, and the two can be spliced ​​together as a whole by splicing plates. The plates can be connected together by welding, bolting or other connection methods.

[0045] A feeder 73 and a floating support assembly 3 can be installed on the bed appendage 10. Thus, the floating support assembly 3 is used to cooperate with the feeder 73 to transport the pipe, so that the chuck 2 can clamp the pipe.

[0046] like Figure 3 and 4 The figure shows a pipe cutting machine using the present device, which adopts a side-hung structure to ensure stable mechanical operation while retaining the main advantages of the original wall-mounted structure. Zero tailing cutting can be achieved using simple logical actions. The feeder is directly inserted into the center bottom of the chuck, which greatly improves the feeding rhythm, and the overall feeding speed is increased by more than 80% compared with the above structure. The machine tool has a solid and stable structure, uniform force and good load-bearing capacity, and is suitable for processing all kinds of pipes. Claws 21 are provided on both sides of the chuck 2 of the present device, so when the cutting head 104 is cutting, it can achieve tail-free cutting in cooperation with the rear chuck.

[0047] The existing pipe cutting machine loading process is as follows: 1. The previous pipe is cut; 2. The chuck is reset; 3. The pipe is conveyed; 4. The length is measured; 5. The jaws clamp a single pipe; 6. The jaws "feed" the material; 7. The chuck clamps the pipe; 8. The support is supported by the support member; 9. The jaws are released; 10. The jaws are retracted; 11. The chuck is fed to start cutting.

[0048] The device can transfer and measure the length of the pipe while cutting the previous pipe. The length measurement can be performed while the pipe is still being transferred on the feeding mechanism. Then the following process is performed: the chuck is reset; the floating support props up the pipe; the chuck clamps the pipe; the chuck feeds and starts cutting.

[0049] The feeding mechanism of the device realizes the synchronous cutting of the upper pipe and the feeding process of the lower pipe, reduces the cumbersome process of feeding by the clamping jaws, reduces the logical actions, and thus shortens the feeding cycle.
