Description

Technical Field

[0001] The utility model relates to the field of heading pipe bending machines, in particular to an automatic feeding and heading pipe bending integrated machine. Background Art

[0002] In modern industrial manufacturing, the processing and forming of metal pipes are essential steps. Heading and bending metal pipes, as crucial processing steps, are widely used in a variety of fields, including but not limited to construction, automotive, machinery manufacturing, aerospace, power generation, chemicals, and medical devices. Heading and bending metal pipes, as needed, can improve the efficiency of metal pipe connections. Therefore, to meet the demands of high-efficiency, high-precision, and highly automated production, automatic loading, heading, and bending machines have emerged.

[0003] The heading processing of metal pipes is mainly used to make the end connection structure of pipe fittings or to facilitate the subsequent connection requirements of close welding processing, thereby improving the subsequent processing efficiency. The pipe bending processing changes the straight shape of the metal pipe to form a bend of a certain angle or shape to meet specific installation or use requirements.

[0004] However, there are still some defects and shortcomings in the actual application process. First, the existing heading and bending of metal pipes usually require two processes through a heading machine and a bending machine respectively. Therefore, the metal pipe needs to be processed twice during the forming process, resulting in low processing and production efficiency of the metal pipe. Secondly, after completing one process of heading or bending, it is necessary to transport and move it, and to re-perform tedious loading and positioning, which affects production efficiency and processing accuracy. In addition, repeated positioning processing can easily affect the adaptability and efficiency of processing, resulting in certain limitations in the processing and production of metal pipes. Utility Model Content

[0005] The purpose of the present invention is to solve the above defects and provide an automatic feeding, heading and bending integrated machine to solve the technical problem in the above background technology that it is difficult to head and bend metal pipes, thereby affecting the production efficiency of metal pipes.

[0006] The purpose of this utility model is achieved by the following methods:

[0007] The automatic loading and heading pipe bending machine includes a cabinet and a workbench arranged on the cabinet, the workbench is provided with a loading mechanism and a clamping mechanism, the clamping mechanism is connected to a pipe positioning block, the workbench is provided with a pipe bending mechanism and a heading mechanism, the pipe bending mechanism and the heading mechanism are respectively located on both sides of the clamping mechanism, the end of the heading mechanism extending toward the clamping mechanism is connected to a heading mold, an arc-shaped groove is provided on the surface of the workbench close to the pipe bending mechanism, the workbench is detachably connected to the pipe bending mold through a rotating part, one end of the rotating part is connected to a linkage block, the linkage block is connected to the pipe bending mechanism through a connecting shaft passing through the arc groove, when the clamping end of the pipe bending mechanism extends toward the pipe bending mold, the pipe bending mold is driven by the rotating part to rotate, and drives the pipe bending mechanism to rotate to complete the bending of the pipe.

[0008] Further described in the above description, the heading mechanism is composed of a heading cylinder and a heading mounting seat. The heading cylinder is installed on the workbench, and the telescopic end of the heading cylinder extends toward the clamping mechanism and is connected to the heading mounting seat. The heading mold is detachably installed on the side of the heading mounting seat close to the clamping mechanism, and a pressing protrusion for pressing the end of the pipe is formed on the heading mold.

[0009] Optionally, the heading die can be disassembled and replaced according to the size of the pipe to improve the applicability of the equipment, and the end of the pipe can be extruded and formed by the pressing protrusion on the heading die under the drive of the heading cylinder.

[0010] The above description further states that the rotating part is composed of a rotating shaft, a gear, a rack and a driving cylinder. The rotating shaft is installed on the workbench through a mounting bracket, and one end of the rotating shaft passes through the gear and is connected to the pipe bending mold. The gear is meshed with the rack, and one end of the rack is connected to the telescopic shaft of the driving cylinder.

[0011] The telescopic shaft of the driving cylinder can drive the rack to rotate the gear. When the gear drives the rotating shaft to rotate, the rotating shaft can drive the bending mold and the bending mechanism through the connecting shaft on the linkage plate to rotate at the same time, so that the pipe can be bent to the corresponding angle.

[0012] The above description further states that the pipe bending mechanism includes a connecting block, a pipe bending cylinder, and a pipe bending pressure block. The connecting block is connected to one end of a connecting shaft, the pipe bending cylinder is mounted on the connecting block, and the telescopic end of the pipe bending cylinder is connected to the pipe bending pressure block. A bending cavity for holding the pipe is formed between the pipe bending pressure block and the pipe bending die. As the connecting shaft moves along the arc-shaped notch, the connecting block is driven to rotate about the rotation axis, thereby bending the pipe in the bending cavity.

[0013] Further, the clamping mechanism comprises a clamping cylinder, a clamping block, and a support plate, the support plate being mounted on a workbench, the clamping cylinder being mounted on the support plate, and the telescopic end of the clamping cylinder being connected to the clamping block, the clamping mechanisms being relatively arranged.

[0014] Further to the above description, the feeding mechanism includes two symmetrically arranged material plates, a support frame, and a limiting cylinder. The support frame is mounted on a workbench. The two material plates are symmetrically mounted on the support frame, with a material discharge trough formed between the two material plates. The limiting cylinder is mounted on the material plates, and the telescopic end of the limiting cylinder extends toward the material discharge trough. The telescopic end of the limiting cylinder can limit the position of the pipe in the material discharge trough, so that only one pipe is discharged at a time.

[0015] Further, in the above description, a feeding shaft is connected between the two material plates, a feeding cam is connected to the feeding shaft, and the feeding cam is exposed on the material discharge chute.

[0016] Further in the above description, the workbench is connected to a unloading assembly through a mounting frame, and the unloading assembly consists of a unloading rod, a receiving rod and a unloading cylinder. The unloading rod is in contact with the open end of the unloading trough, and the unloading rod and the receiving rod are arranged in parallel through a connecting plate, and the ends of the unloading rod and the receiving rod are connected through a swing rod, and the telescopic end of the unloading cylinder is connected to the swing rod.

[0017] A connecting rod structure is formed by the blanking rod, the receiving rod and the swing rod. The swing rod is inclined to connect the blanking rod and the receiving rod so that the end of the blanking rod is exposed at the end of the receiving rod. When the telescopic rod of the blanking cylinder is extended, the blanking rod moves closer to the blanking cylinder, and the receiving rod is moved away from the blanking cylinder under the action of the swing rod, thereby supporting the blanked pipe.

[0018] The beneficial effects of the present invention are as follows: the pipe is stably clamped by the clamping mechanism, and the head mechanism extends to the end portion of the clamping mechanism and the connecting shell is detachable to the head mold, so that the head mechanism performs pressure forming and head processing on the pipe clamped by the clamping mechanism through the head mold, thereby improving processing accuracy and processing efficiency. The bending mold is detachably connected to the workbench through a rotating part, so that bending molds of different specifications can be easily replaced, thereby increasing the applicability and flexibility of the equipment. When the clamping end of the bending mechanism extends and abuts the bending mold, the bending mold can be driven by the rotating part to rotate, and under the rotation of the rotating part, the bending mold is driven by the connecting shaft to rotate along the arc groove as a trajectory, thereby ensuring the accuracy and consistency of the bending, improving the stability and efficiency of the bending, and making it possible to perform head and bending processing on both ends of the pipe respectively, thereby improving the convenience of operation, realizing the automation of the pipe heading and bending processing process, and improving production efficiency.

When the clamping end of the pipe bending mechanism extends toward the pipe bending die 7, the pipe bending die 7 is driven by the rotating member 6 to rotate, and drives the pipe bending mechanism to rotate to complete the bending of the pipe.

[0029] In this embodiment, the heading mechanism is composed of a heading cylinder 10 and a heading mounting seat 11. The heading cylinder 10 is installed on the upper surface of the workbench 2, and the telescopic end of the heading cylinder 10 extends toward the clamping mechanism and is connected to the heading mounting seat 11. The heading mold 4 is detachably installed on the side of the heading mounting seat 11 close to the clamping mechanism, and a pressing protrusion for pressing the end of the pipe is formed on the heading mold 4.

[0030] Optionally, the heading die 4 can be disassembled and replaced according to the size of the pipe to improve the applicability of the equipment, and the end of the pipe can be extruded and formed by the pressing protrusion on the heading die 4 under the drive of the heading cylinder 10.

[0031] In this embodiment, the rotating part 6 is composed of a rotating shaft 61, a gear 62, a rack 63 and a driving cylinder 64.

A feed shaft 35 is connected between the two feed plates 31. The feed shaft 35 is connected to a feed cam 36, which is exposed on the feed chute 34. One end of the feed shaft 35 is connected to a drive motor 37. The drive motor 37 is connected to the feed shaft 35 via a belt connector, so that the rotation of the feed shaft 35 drives the feed cam 36 to feed and discharge the pipes.

[0036] In this embodiment, a blanking assembly 19 is connected to the workbench 2 through a mounting frame 12. The blanking assembly 19 consists of a blanking rod 191, a receiving rod 192 and a blanking cylinder 193. The blanking rod 191 abuts against the open end of the blanking trough 34. The blanking rod 191 and the receiving rod 192 are arranged in parallel through a connecting plate 194, and the ends of the blanking rod 191 and the receiving rod 192 are connected by a swing rod 195. The telescopic end of the blanking cylinder 193 is connected to the swing rod 195. A connecting rod structure is formed by the discharge rod 191, the receiving rod 192 and the swing rod 195. The swing rod 195 is inclined to connect the discharge rod 191 and the receiving rod 192, so that the end of the discharge rod 191 is exposed at the end of the receiving rod 192. When the telescopic rod of the discharge cylinder 193 is retracted, the discharge rod 191 moves closer to the discharge cylinder 193, and the receiving rod 192 is moved away from the discharge cylinder 193 under the action of the swing rod 195, so as to support the discharged pipe.

[0037] The specific operating principle of this embodiment is as follows: for blanking, the metal pipe to be headed and bent is placed in the blanking trough 34 between the material plates 31 so that it can be blanked downwards, and the pipe near the open end of the blanking trough 34 is isolated from the pipe in the blanking trough 34 by the limit cylinder 33, and the swing rod 195 is driven by the blanking cylinder 193 to drive the blanking rod 191 and the receiving rod 192 to move, so that the blanking rod 191 opens the open end of the blanking trough 34, and the pipe falls onto the receiving rod 192 to complete the connection, thereby improving the automation and efficiency of blanking, thereby driving the clamping plates 31 to stably clamp the pipe through the clamping cylinders 16 arranged opposite to each other in the front and rear;

[0038] Heading processing: After connecting the corresponding heading die 4 and the pipe bending die 7, the heading mechanism performs pressure-forming and heading processing on one end of the clamped pipe through the pressure-forming protrusion of the heading die 4, thereby improving the processing accuracy and processing efficiency;

[0039] During pipe bending, when the pipe bending block 15 connected to the pipe bending cylinder 14 extends and abuts against the pipe bending die 7, the driving cylinder 64 drives the rack 63 to move, and the rotation of the gear 62 can drive the rotating shaft 61 to rotate, thereby driving the pipe bending die 7 and the linkage plate to rotate under the rotation of the rotating shaft 61, so that the pipe bending block 15 and the pipe bending die 7 clamp and bend the pipe, ensuring the accuracy and consistency of the pipe bending, and improving the stability and efficiency of the pipe bending. After the processing is completed, the clamping cylinder releases the pipe, and the pipe falls into the discharge chute of the cabinet 1 and enters the next process, thereby realizing the automation of the pipe heading and pipe bending processing process, and improving production efficiency.
