Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a cutting machine feeding assembly. Background Technology

[0002] The feeding assembly of the cutting machine is used for conveying, positioning, and clamping stainless steel pipes. The feeding position is controlled by the transmission and clamping mechanism to ensure cutting accuracy. In existing technology, the material lacks effective limiting on both sides as it moves on the conveyor rollers, making it difficult to clamp the cutting point and affecting the cut quality. Furthermore, long materials require custom-made long support platforms, which are costly; segmented support platforms are usually connected by welding or bolts, which is cumbersome, inefficient, and difficult to adapt flexibly to different working conditions. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the existing technology where the material is not effectively limited on both sides when it is conveyed on the conveying component, and when a long material is conveyed to the bottom of the cutting machine for equal-segment cutting, it is not convenient to clamp and fix the cutting point, which affects the cutting quality. Customizing the equal-length support platform according to the length of the material is costly, and the connection is not convenient when placing the support platform in equal segments. Therefore, a cutting machine feeding component is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cutting machine feeding assembly includes a saw, wherein multiple receiving frames are placed on one side of the feeding end, and adjacent receiving frames are connected by two connecting frames.

[0006] The top of the receiving frame is equipped with opposing clamping frames along the pipe conveying direction. Multiple rollers are rotatably connected inside the clamping frames. The rotation axis of the rollers is perpendicular to the pipe conveying direction. The relative distance between the clamping frames can be adjusted.

[0007] Multiple conveying rollers are rotatably mounted on the top of the receiving frame, and the rotation axis of the conveying rollers is perpendicular to the conveying direction of the pipe fitting.

[0008] In one possible implementation, the length direction of the top frame is the pipe conveying direction, the width direction of the top of the top frame is provided with a groove, and the bottom of the clamping frame is provided with a corresponding slider. The clamping frame can slide along the width direction of the top frame through the slider and the groove. The bottom of the clamping frame is fixedly connected to an extension block, which is threaded onto the positive and negative thread sections of the bidirectional screw. The bidirectional screw is rotatably installed on the top frame.

[0009] In one possible implementation, the connecting frame consists of a bidirectional internally threaded tube and a lead screw, with a rotating sleeve fixedly connected to the end of the lead screw, and corresponding connecting parts provided on the legs of adjacent receiving frames.

[0010] In one possible implementation, the connector includes a connecting plate fixed to the outrigger, a rotating shaft fixedly connected to one side of the connecting plate, and a rotating sleeve fitted onto the rotating shaft.

[0011] In one possible implementation, a positioning component is provided between the rotating sleeve and the rotating shaft.

[0012] In one possible implementation, the positioning component includes an insertion hole on the rotating sleeve, a matching through hole on the rotating shaft, and a connector including a limiting end 7 and a plug rod, the plug rod passing through the insertion hole, and the bottom of the limiting end 7 fitting against the outer wall of the rotating sleeve.

[0013] In one possible implementation, a handle is fixedly sleeved on the outer wall of the bidirectional lead screw.

[0014] In one possible implementation, a conveyor frame is fixedly installed at the feed end of the saw, and multiple rotating rollers are rotatably installed on the top of the conveyor frame.

[0015] In this application, multiple receiving frames are placed sequentially on one side of the feed end of the saw. Based on the distance between two receiving frames, a bidirectional internal threaded tube is rotated. The bidirectional internal threaded tube adjusts the distance between two lead screws. A rotating sleeve, with its ends furthest from each other, is fitted onto a rotating shaft, thus achieving connection. An insert rod is then inserted into the insertion holes of the rotating sleeve and the rotating shaft. After insertion, the bottom of the limiting end fits against the top of the rotating sleeve. The stainless steel pipe is placed on the conveying roller. Based on the required clamping size when the stainless steel is clamped and cut below the saw, the bidirectional lead screw is rotated. The positive and negative thread sections on the outer wall of the bidirectional lead screw adjust the distance between two extension blocks, thereby adjusting the distance between the two clamping frames. Simultaneously, two L-shaped sliders at the bottom of the clamping frames slide within corresponding grooves. When the stainless steel pipe is conveyed below the saw, rollers rotate within the clamping frames, assisting in the movement of the stainless steel pipe.

[0016] Beneficial effects: In this utility model, the cutting machine feeding assembly can quickly adapt to the spacing of adjacent receiving frames through the threaded engagement of the bidirectional internal threaded tube in the connecting frame and the two lead screws. With the plug-in connection structure of the rotating sleeve and the rotating shaft, it can realize the rapid assembly and positioning of multiple units, adapt to the distance between two adjacent receiving frames, thereby meeting the feeding requirements and improving the versatility of the equipment.

[0017] In this utility model, the feeding assembly of the cutting machine, when the bidirectional lead screw is rotated, its positive and negative thread sections drive the two extension blocks to move synchronously in opposite directions or in opposite directions, thereby driving the clamping frame to accurately adjust the spacing. It can be adapted to stainless steel pipes of different diameters or different numbers, ensuring that the pipes at the cutting point are stably limited, avoiding sliding and offset, and improving the processing accuracy.

[0018] In this invention, the synergistic effect of spacing adjustment and bidirectional screw clamping adjustment not only meets the need for rapid adaptation of multiple specifications of pipe fittings, but also ensures cutting stability. With the assistance of roller conveying, it significantly improves production efficiency and processing quality. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In one embodiment: Refer to Figure 1 and Figure 2 A feeding assembly for a cutting machine comprises a saw 1, multiple receiving frames 3, and a connecting frame. Multiple receiving frames 3 are arranged sequentially on one side of the feeding end of the saw 1. Two clamping frames 6 are symmetrically arranged on the top of each receiving frame 3. Multiple rollers 20 are rotatably installed within the clamping frames 6. Figure 2 The roller 20 shown is actually a rotating roller, and the adjacent receiving frame 3 is connected and fixed by a connecting frame.

[0027] The clamping frame 6 is arranged along the conveying direction of the feeding assembly, and multiple rollers 20 are arranged perpendicular to the conveying direction of the feeding assembly, so that when the clamping frame 6 is located on both sides of the pipe to be conveyed, the multiple rollers 20 can roll and contact the sides of the pipe.

[0028] Reference Figure 2 The main body of the receiving frame 3 is a frame structure composed of a top frame 4 and a support leg 11. The top frame 4 is fixed to the top of the support leg 11. A bidirectional screw 10 is arranged horizontally inside the top frame 4. The direction of pipe conveying is the longitudinal direction, and the direction perpendicular to the longitudinal direction is the transverse direction. The bidirectional screw 10 has a center node. One end of the bidirectional screw 10 has a positive thread and the other end has a negative thread. The middle part of the bidirectional screw 10 is rotatably connected to the top frame 4 through a bearing seat.

[0029] L-shaped sliders 7 are welded to both sides of the bottom of the clamping frame 6. Two horizontally arranged sliding grooves 5 are opened on the top of the top frame 4. The L-shaped sliders 7 are slidably fitted into the sliding grooves 5 so that the clamping frame 6 can slide laterally.

[0030] The bottom of each of the two clamping frames 6 has an extension block 9 with a threaded hole. The threaded hole is configured to cooperate with the double-acting screw 10. The threaded hole of one extension block 9 is connected to the forward thread of the double-acting screw 10, and the threaded hole of the other extension block 9 is connected to the reverse thread of the double-acting screw 10. In actual use, when the double-acting screw 10 is manually rotated, the double-acting screw 10 drives the two clamping frames 6 to move closer or further apart through the threaded engagement. The threaded hole and the forward and reverse threads of the double-acting screw 10 have a certain self-locking effect.

[0031] In order to make the pipe fittings pass through the receiving frame 3 more smoothly, a transverse conveying roller 8 is provided on the top of the top frame 4. The two ends of the conveying roller have mounting shafts arranged along the axis, and the mounting shafts are rotatably connected to the top frame 4 through bearing seats.

[0032] In actual use, the conveying roller 8 can support the bottom of the pipe and the roller 20 can support both sides of the pipe, so that the sliding friction can be transformed into rolling friction during the conveying process, making the conveying of the pipe smoother.

[0033] The conveying roller 8 is configured to cooperate with the roller 20 of the clamping frame 6. Specifically, the top surface of the conveying roller 8 is higher than the top of the receiving frame 3 and lower than the roller 20, so that when the pipe is supported on the conveying roller 8, both sides of the pipe can roll in contact with the roller 20. The conveying roller 8 is located in the area below the clamping frame 6.

[0034] Reference Figures 3 to 5 The connecting frame consists of a bidirectional internally threaded tube 12 and two lead screws 15. The inner wall of the bidirectional internally threaded tube 12 has internal threads, one end of which is a forward internal thread and the other end is a reverse internal thread. The lead screw 15 has an external thread that matches the internal thread. A rotating sleeve 13 is fixed to one end of the lead screw 15. The rotating sleeve 13 is a ring with a through hole in the middle. The outer wall of the ring is fixedly connected to one end of the lead screw 15. The through hole is located in a direction perpendicular to the axis of the lead screw 15. An insertion hole 18 is provided on the ring.

[0035] A connecting plate 19 is fixed on each of the legs 11 located on the side adjacent to the front support frame 3 and the rear support frame 3. A rotating shaft 14 is vertically fixed on the surface of the connecting plate 19. A through hole that matches the insertion hole 18 is opened on the rotating shaft 14. A rotating sleeve 13 is sleeved on the outer wall of the rotating shaft 14. The rotating shaft 14 and the rotating sleeve 13 are positioned by inserting a connector through both the insertion hole 18 and the through hole. The connector includes a limiting end 17 at the top and a plug rod 16 at the bottom. The limiting end 17 is used to prevent the plug rod 16 from coming out.

[0036] Reference Figure 1 and Figure 2 The feed end of the sawing machine 1 is fixedly installed with a conveyor frame 2. The conveyor frame 2 is located between the sawing machine 1 and the receiving frame 3. Multiple rotating rollers are rotatably installed on the top of the conveyor frame 2. The axis of the rotating rollers is arranged in the transverse direction. Both ends of the rotating rollers have mounting shafts in the axial direction. The rotating rollers are rotatably installed with the conveyor frame 2 through the mounting shafts and bearing seats.

[0037] A handle is fixedly installed at the end of the bidirectional lead screw 10 for easy operation and adjustment.

[0038] This application can be used in the field of cutting machines, or in other fields applicable to this application.

[0039] In another embodiment: Reference Figure 1 , Figure 3 and Figure 4 A cutting machine feeding assembly is applied in the cutting machine field. During assembly, multiple receiving frames 3 are placed sequentially along the feeding direction according to the length of the material. When the bidirectional internal thread tube 12 rotates in the forward direction, the lead screws 15 at both ends of the bidirectional internal thread tube 12 move away from the bidirectional internal thread tube 12 along the axial direction. When the bidirectional internal thread tube 12 rotates in the reverse direction, the lead screws 15 at both ends of the bidirectional internal thread tube 12 move closer to the bidirectional internal thread tube 12 along the axial direction. Adjusting the bidirectional internal thread tube 12 causes the two lead screws 15 to extend and retract, so that the length of the bidirectional internal thread tube 12 and the lead screws 15 can match the adjustment of the spacing between adjacent receiving frames 3.

[0040] In actual use, when it is necessary to adjust the spacing between adjacent support frames 3, the plug can be pulled out first, so that the bidirectional internal threaded tube 12 and the lead screw can be pulled out. Then, the spacing between adjacent support frames 3 can be adjusted. Then, the extension length of the two lead screws 15 can be adjusted. When the extension length of the two lead screws 15 is matched with the spacing between adjacent support frames 3, the rotating sleeve 13 at the end of the lead screw 15 is put into the rotating shaft 14 of the support leg 11, the plug rod 16 is inserted and the limiting end 17 is pressed against the rotating sleeve 13 to complete the quick connection and positioning of the support frame 3.

[0041] refer to Figure 1When conveying materials, place the stainless steel pipe fittings on the surface of the conveying roller 8, rotate the handle at the end of the double-acting screw 10, and drive the two extension blocks 9 to move in opposite directions or in the opposite direction through the positive and negative thread sections, thereby driving the clamping frame 6 to slide along the slide groove 5 through the L-shaped slider 7. Adjust the distance between the two clamping frames 6 to match the diameter or quantity of the pipe fittings.

[0042] When the pipe is conveyed towards the sawing machine 1, the rollers 20 inside the clamping frame 6 rotate to assist in the movement, and the rotating rollers of the conveying frame 2 receive the pipe and guide it to the cutting position. During the cutting process, the clamping frame 6 forms a limit on both sides of the pipe cutting point to prevent slippage and deviation. A clamping device is provided at the cutting blade of the sawing machine 1 to clamp the conveyed pipe (not shown in the figure).

[0043] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
