Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing equipment, in particular to an automatic punching device for pipe fittings. Background Art

[0002] In the pipe processing equipment industry, due to practical needs, the surface of the round pipe is usually punched. In the past, many technologies for pipe punching were performed by manual fixation or manual rotation. Due to the limitations of manual operation, it is impossible to guarantee continuous operation and product consistency, and it also greatly reduces production efficiency and increases labor costs. Therefore, this manual operation method has gradually been eliminated by the market. Now, mechanical equipment is mostly used to replace some manual operations. For example, in the punching process, it used to be necessary to manually deliver the material to the punching die, fix it manually, and then manually remove the material after the punching is completed. Now, it can be changed to mechanical equipment to deliver the material to the punching die, and automatically remove the material after the punching is completed, without the need for manual participation in the whole process.

[0003] For example, the fully automatic round tube punching machine disclosed in Chinese patent CN105458069A has the following punching operation method: the pipe to be processed is placed in the groove of the push rack, and then the push rack is driven by the cylinder to move on the work surface, so that the pipe is sent into the die base, and punched by the punch. In this way, the automatic punching of the pipe is realized, but although the above-mentioned punching equipment has realized the automated operation method to a certain extent, it still has some problems, such as the inability to realize the punching of the round tube at different angles. In other words, if the equipment is used to punch the round tube at different angles, it is necessary to wait for the first punching operation to be completed, and after the round tube is withdrawn from the die base, the operator removes the round tube, changes the direction, puts the pipe again in the groove, and then sends it back into the die base for punching. This method greatly reduces the efficiency of punching.

[0004] Therefore, it is necessary to improve on the basis of the existing technology and provide an automated equipment that can better punch holes in pipe fittings, so as to realize punching operations at different angles of pipe fittings, thereby improving the punching efficiency and reducing the production cost of the enterprise.

[0029] refer to Figure 1-7 The utility model provides an automatic punching device for pipe fittings, comprising a first driving part 2, a second driving part 3, a punching mechanism 4 and a clamping mechanism 5, wherein the punching mechanism 4 is arranged at a distance on one side of the clamping mechanism 5, and the first driving part 2 and the second driving part 3 are respectively connected to the punching mechanism 4 and the clamping mechanism 5; the punching mechanism 4 comprises a punching knife 41 and a receiving area 42, wherein the receiving area 42 is mainly used to place the pipe fittings to be processed, plays a supporting role, and is also a working area for the punching knife 41; the first driving part 2 can drive the punching knife 41 to move toward the receiving area 42; the second driving part 3 can drive the clamping mechanism 5 to move toward the receiving area 42, and the clamping mechanism 5 comprises a third driving part 51, a rotating rod 52 and a clamping piece connected in sequence, and the third driving part 51 can drive the clamping piece to rotate through the rotating rod 52.

[0030] refer to Figure 1-7 The specific working process of the automatic punching device for pipe fittings provided by the utility model is as follows:

[0031] The pipe to be processed is clamped and fixed by the clamping member, and then the second driving part 3 drives the clamping mechanism 5 to move toward the accommodating area 42, and the pipe is sent to the accommodating area 42 for fixing, and then the first driving part 2 drives the punching knife 41 to move toward the accommodating area 42. During the movement of the punching knife 41, it gradually abuts against the pipe, thereby realizing the punching operation on the pipe. When the punching knife 41 completes the first punching operation, the third driving part 51 drives the clamping member to rotate through the rotating rod 52, so as to change the punching angle of the pipe during the rotation, and then the punching knife 41 performs a second punching operation on the pipe, so as to realize that the pipe can be punched at different angles at one time, without the need to manually adjust the punching angle of the pipe as in the past, which is more convenient and also improves the efficiency of punching.

[0032] refer to Figure 1-7 In a preferred embodiment, the punching mechanism 4 further includes a die base 43, and the accommodating area 42 is arranged on the die base 43. The die base 43 is also provided with an active groove 44 for the punching knife 41 to move. The active groove 44 is connected to the accommodating area 42, and the first driving part 2 can drive the punching knife 41 to move toward the accommodating area 42; there are multiple punching knives 41, and the multiple punching knives 41 are arranged at intervals. In this embodiment, the number of punching knives 41 can be freely set according to the actual production needs. By setting multiple punching knives 41, it is possible to punch multiple holes on the pipe fitting at one time, which has a better effect. The punching knife 41 enters the accommodating area 42 through the active groove 44, thereby punching the pipe fitting. In this embodiment, the accommodating area 42 includes a feed port, and the clamping mechanism 5 is arranged at intervals on one side of the feed port, and no matter in which direction the feed port is arranged, the clamping mechanism 5 is always located on one side of the feed port, so that the pipe fitting can be sent into the accommodating area 42.

[0033] refer to Figure 1-7 In a preferred embodiment, the clamping mechanism 5 also includes a fixed seat 54, the third driving part 51 is located on one side of the fixed seat 54, the clamping member is located on the other side of the fixed seat 54, and the rotating rod 52 is connected between the clamping member and the third driving part 51; the fixed seat 54 is also connected to the second driving part 3; the second driving part 3 can drive the clamping member to move toward the accommodating area 42 through the fixed seat 54.

[0034] refer to Figure 5 In this embodiment, the specific working process of the clamping mechanism 5 is as follows: the power output end of the second driving part 3 is connected to the fixed seat 54, and the third driving part 51, the rotating rod 52 and the clamping piece are all located on the fixed seat 54. Therefore, when the second driving part 3 drives the fixed seat 54 to move toward the accommodating area 42, it will also drive the clamping piece to move toward the accommodating area 42, thereby delivering the pipe to the accommodating area 42; and when the punching knife 41 completes the first operation, the third driving part 51 drives the clamping piece to rotate through the rotating rod 52, thereby changing the punching angle of the pipe, thereby realizing the punching operation of different positions of the pipe. The whole process does not require manual participation, making the entire punching operation process more efficient.

[0035] refer to Figure 4-5 In a preferred embodiment, the fixing seat 54 is further provided with a fourth driving part 55 and a connecting member 56, the connecting member 56 is connected to the outer side of the rotating rod 52, the clamping member includes a clamping claw 53, one end of the connecting member 56 is connected to the fourth driving part 55, and the other end is connected to the clamping claw 53, and the fourth driving part 55 can drive the clamping claw 53 to open or contract through the connecting member 56. Figure 5 The connecting member 56 is connected to the outer wall of the rotating rod 52, and there is a space between the inner wall of the connecting member 56 and the outer wall of the rotating rod 52 for the connecting member 56 to move. The third driving part 51 is connected to the connecting member 56, and the third driving part 51 can drive the connecting member 56 to move forward and backward (the forward and backward movement referred to here is based on Figure 5 For reference, the direction toward the clamping jaw 53 is forward, and the opposite direction is backward). When the fourth driving part 55 drives the connecting member 56 to move forward, a thrust is generated on the clamping jaw 53, so that the clamping jaw 53 contracts, and the pipe fitting can be clamped. When the fourth driving part 55 drives the connecting member 56 to move backward, a pulling force is generated on the clamping jaw 53, so that the clamping jaw 53 opens, and the pipe fitting can be loosened. In addition, during the processing of the pipe fitting, the clamping jaw 53 always keeps the pipe fitting clamped, so the stability is better, and the pipe fitting is not easy to shake during the punching process.

[0036] refer to Figure 1-7In the preferred embodiment, it also includes a feeding mechanism 6, which is located on one side of the clamping mechanism 5. The feeding mechanism 6 includes a conveying part and a loading part, and the conveying part is located between the clamping mechanism 5 and the loading part; the conveying part includes a transverse driving member 61 and a clamping arm 63, and the transverse driving member 61 can drive the clamping arm 63 to reciprocate between the loading part and the clamping mechanism 5. In this embodiment, the loading part is mainly used to store the pipes to be processed, and then the transverse driving member 61 drives the conveying part to transport the pipes at the loading part to the clamping claw 53 of the clamping mechanism 5, and then the workpiece is clamped by the clamping claw 53 and sent to the processing area, thereby achieving an automatic loading effect, and there is no need to load the material manually as in the past, so that the punching efficiency is higher.

[0037] refer to Figure 1-7 In a preferred embodiment, the conveying part further includes a longitudinal driving member 62, which can drive the clamping arm 63 to move up and down; the clamping arm 63 includes a base plate 631 and two clamping blocks 632, one end of the base plate 631 is connected to the longitudinal driving member 62, and the other end of the base plate 631 is provided with a slide groove for the clamping blocks 632 to move, and the two clamping blocks 632 are slidably connected in the slide groove, and the base plate 631 is also provided with a fifth driving part 633, which can drive the two clamping blocks 632 to connect or separate with each other. When the two clamping blocks 632 are connected with each other, the workpiece is clamped, and when the two clamping blocks 632 are separated from each other, the workpiece is released.

[0038] Specifically, the overall working process of the feeding mechanism 6 is as follows: first, the clamp arm 63 is driven to reciprocate between the feeding part and the clamping mechanism 5 by the transverse driving member 61. When the transverse driving member 61 drives the clamp arm 63 to move to the position of the feeding part, the longitudinal driving member 62 drives the clamp arm 63 to move downward, and then the fifth driving member 633 drives the two clamping blocks 632 to move to clamp the workpiece. After the clamp arm 63 clamps the workpiece, the longitudinal driving member 62 drives the clamp arm 63 to move upward, and then the transverse driving member 61 drives the clamp arm 63 to move toward the clamping mechanism 5. When it moves to the front of the clamping jaw 53, the clamping jaw 53 clamps the workpiece. At this time, the clamp arm 63 releases the workpiece, and the clamping jaw 53 moves to send the workpiece to the accommodating area 42 for punching. Then the transverse driving member 61 drives the clamp arm 63 back to the position of the feeding part to clamp the workpiece, and so on and so forth to realize the clamping and conveying of the pipe fittings. The whole process is carried out in an automated manner, without the need for manual participation, thereby improving the processing efficiency.

[0039] refer to Figure 1-7In a preferred embodiment, the feeding part includes a first baffle 64, a second baffle 65 and a connecting rod 66. The first baffle 64 and the second baffle 65 are respectively connected to the two ends of the connecting rod 66. There are multiple connecting rods 66, and the multiple connecting rods 66 are arranged at intervals. The feeding part also includes a motor 67. The output end of the motor 67 is connected to the first baffle 64. The motor 67 can drive the first baffle 64 to approach or move away from the second baffle 65. The distance between the two baffles can be adjusted by the motor 67 to adapt to the length of the pipe fittings in the actual production process. In other words, the distance between the two baffles can be adjusted according to the actual size and length of the pipe fittings. Therefore, only one set of equipment is needed to process pipe fittings of different sizes, which saves production costs and improves work efficiency.

[0040] refer to Figure 4 and 7 In a preferred embodiment, the first baffle 64 and the second baffle 65 are both provided with a first inclined plate 68 and a second inclined plate 69 on their inner side walls.

There are two support blocks 73, which are arranged at intervals, and a groove is also provided on the support block 73. The cylinder 70 drives the support block 73 to move upward, so that the pipe at the front end of the first inclined plate 68 can be lifted upward, so that the clamp arm 63 can clamp the pipe. When the support block 73 lifts the pipe upward, the two ends of the pipe will be located in the grooves of the support block 73 to prevent the pipe from falling, and then the clamp arm 63 can clamp and transport the pipe.
