Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a short tube punching and tube end forming integrated machine. Background Art

[0002] The short tube punching forming process is a precision hole processing technology for tubular materials based on the principle of pressure processing. It applies a directional load to the tube wall through a mold or CNC equipment to achieve plastic forming of a specific shape of hole structure. The core goal of this process is to ensure the accuracy of the hole size, the uniformity of the wall thickness around the hole and the surface quality, while suppressing the deformation and burrs of the tube body caused by the hollow structure. The tube end forming process involves operations such as hole expansion and hole shrinkage, and the tube end needs to be radially or axially deformed by the mold to meet the structural assembly requirements.

[0003] Multiple machines realize the forming of short and small tube ends, anisotropic forming of tube ends, punching and flanging process modes. It is necessary to manually transfer and flip the tube body to complete the double-end and punching processing, which leads to redundant processes (an average of 3 to 5 auxiliary processes are added), resulting in reduced efficiency, and the increase in the frequency of manual intervention leads to increased labor intensity. Taking the Chinese patent announcement number CN206483920U as an example, although the fully automatic double-head tube end forming machine disclosed in it adopts a slide-type double-station structure to achieve synchronous processing, it still has significant technical defects: first, the switching of the shrinking / expansion process depends on the mold replacement, resulting in increased downtime of the production line; second, the equipment has a single function and cannot integrate the punching process. It is necessary to configure special stamping equipment additionally, resulting in a split process flow. Especially in the processing of high-precision heat dissipation pipe fittings (such as air conditioning refrigeration copper pipes), the cumulative error caused by multiple clamping can reach ±0.15mm, which directly affects the product air tightness index. Therefore, the development of a multifunctional equipment integrating the punching tube end forming composite process has become the main direction of the industry's technology upgrade.

[0038] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0039] like Figures 1 to 8 As shown, the present invention requests protection for a short tube punching and tube end forming integrated machine, including a machine platform 1, on which a guide rail 101 is provided, and a front tube end processing component 2 and a punching component 3 are slidably connected to the guide rail 101; the machine platform 1 is also provided with a rear tube end processing component 4 and a conveying and cutting component 5, the conveying and cutting component 5 and the rear tube end processing component 4 are located on the same side of the machine platform 1, and the front tube end processing component 2 and the punching component 3 are located on the same side opposite to the machine platform 1; the front tube end processing component 2 and the rear tube end processing component 4 are both integrated with a tube end forming module 6 including a hole expansion mold 601 and a hole shrinkage mold 602, that is, the front tube end processing component 2 and the rear tube end processing component 4 both have hole expansion and hole shrinkage functions.

[0040] The front tube end processing component 2 includes a support frame 201, which is slidably connected to the guide rail 101. A rack 102 is arranged on the machine 1 along the length direction of the guide rail 101. The support frame 201 and the punching component 3 are respectively provided with a second servo motor 11, and the second servo motor 11 is connected to the gear, and the gear is meshed with the rack 102. The second servo motor 11 drives the gear to mesh with the rack 102 to control the support frame 201 and the punching component 3 to move along the guide rail 101; therefore, the punching component 3 and the front tube end processing component 2 can be driven to move along the guide rail 101 to the conveying and cutting component 5 according to actual conditions, and the tube body punching and front tube end forming processing are performed respectively; after the tube body is punched or the front tube end is formed, the material moving and clamping device 7 arranged on the front tube end processing component 2 will clamp the pipe fitting and transfer it to the rear tube end processing component 4 along the guide rail 101, and the rear tube end forming processing is completed.

[0041] Therefore, by using the front pipe end processing assembly 2, the rear pipe end processing assembly 4 and the punching assembly 3 in combination, the pipe body can be subjected to various processes such as front end processing, punching and rear end processing.

[0042] The hole expansion die 601 and the hole shrinking die 602 are coaxially connected to the rotating main shaft 603, respectively, the rotating main shaft 603 is connected to the driven belt gear 604, the driven belt gear 604 is connected to the driving belt gear 605 through the transmission belt 606, and the driving belt gear 605 is connected to the first servo motor 607. Therefore, the first servo motor 607 drives the rotating main shaft 603 to rotate through the driving belt gear 605, the transmission belt 606 and the driven belt gear 604, and drives the hole expansion die 601 and the hole shrinking die 602 to rotate, so as to perform the hole expansion or hole shrinking process of the tube body.

[0043] Specifically, a first support plate 202 is slidably arranged on the support frame 201, and a tube end forming module 6 and a material moving and clamping device 7 for processing the front tube end are arranged on the first support plate 202. The sliding direction of the first support plate 202 is perpendicular to the sliding direction of the support frame 201 on the guide rail 101; a first linear drive module 203 for controlling the sliding of the first support plate 202 is also arranged on the support frame 201, so as to control the first support plate 202 to approach or move away from one side of the conveying and cutting component 5 and the rear tube end processing component 4. The first linear drive module 203 can be a cylinder or a screw module. In the present embodiment, the first linear drive module 203 is a screw module driven by a servo motor. The first support plate 202 is connected to the screw nut, which is connected to the screw. The servo motor drives the screw to rotate, thereby controlling the movement of the first support plate 202, that is, controlling the tube end forming module 6 and the material moving and clamping device 7 to move toward the conveying and cutting component 5 and the rear tube end processing component 4. In the present embodiment, the material moving and clamping device 7 is a clamping cylinder. Specifically, after the conveying and cutting component 5 outputs the pipe fitting, the tube end forming module 6 of the front tube end processing component 2 moves closer to the conveying and cutting component 5, so that the front end face of the pipe fitting can be expanded or shrunk, and then the processed pipe fitting is clamped by the material moving and clamping device 7, so that it can be moved to the rear tube end processing component 4 to process the other side (that is, the rear end face) of the pipe fitting again.

[0044] The rear tube end processing assembly 4 includes a fixed frame 401 for fixing on the machine 1, a base 402 is slidably arranged on the fixed frame 401, a second support plate 403 is slidably arranged on the base 402, and a tube end forming module 6 for processing the rear tube end is arranged on the second support plate 403, and the sliding direction of the second support plate 403 on the base 402 is perpendicular to the sliding direction of the base 402 on the frame; the base 402 is also provided with a second linear drive module 404 for controlling the sliding of the second support plate 403, so as to control the second support plate 403 to approach or move away from one side of the front tube end processing assembly 2. The second linear drive module 404 has the same structure and working principle as the first linear drive module 203, and will not be described here. That is, the second linear drive module 404 can ultimately control the tube end forming module 6 on the rear tube end processing assembly 4 to approach or move away from the direction of the front tube end processing assembly 2, thereby performing hole expansion or hole shrinkage processing on the rear end face of the pipe fitting.

[0045] The second support plate 403 is also provided with a pipe clamping and forming assembly 8, which is used for processing such as Fig. 9 Metal pipe fittings as shown. Figure 5 as well as Figure 6 As shown, the pipe clamping and forming assembly 8 includes a main frame 801 and a front end plate 802 connected to the main frame 801; a cylinder 803 is arranged on the main frame 801, and a pin 804 is connected to the movable end of the cylinder 803, and the cylinder 803 drives the pin 804 to pass through the front end plate 802; clamping blocks 805 are arranged on both sides of the pin 804, and the clamping blocks 805 are connected to the inclined wedge block 806, and the inclined wedge block 806 is connected to the third linear drive module 807; the structure and principle of the third linear drive module 807 are the same as those of the second linear drive module 404 and the first linear drive module 203; an inclined convex position 8061 is arranged at the front end of the inclined wedge block 806, and the inner side surface of the clamping block 805 is arranged An inclined groove is provided, and the inclined protrusion 8061 is slidably assembled with the inclined groove. The clamping block 805 is provided with a right-angle limiting structure 8051, and the right-angle limiting structure 8051 is used to limit the clamping block 805 from moving forward from the front end plate 802. The clamping block 805 is slidably engaged with the inclined protrusion 8051 and constrained by the right-angle limiting structure 8051. Therefore, the third linear drive module 807 pushes the inclined wedge block 806 to move forward, which will make the clamping blocks 805 on both sides move closer. The third linear drive module 807 pulls the inclined wedge block 806 to move back, which will separate the clamping blocks 805 on both sides. The third linear drive module 807 drives the inclined wedge block 806 to realize the synchronous clamping or release of the tube body by the clamping block 805.

[0046] The working principle of the pipe clamping and forming assembly 8 is that when a metal pipe needs to be processed into a Fig. 9When the end shape is shown, the material moving and clamping device 7 clamps the metal pipe to the pipe clamping and forming assembly 8 and approaches it, and the cylinder 803 drives the pin 804 (in this embodiment, the number of the pins 804 is two, so that the metal pipe can be clamped and processed as shown in FIG. Fig. 9 The double-hole end portion shown in the figure is extended and inserted into the metal pipe; then the third linear drive module 807 controls the clamping blocks 805 on both sides to clamp and shape the metal pipe; then the third linear drive module 807 controls the clamping blocks 805 on both sides to separate and release the clamping, and the pin 804 is recovered under the drive of the cylinder 803, and the metal pipe is formed as shown in the figure. Fig. 9 The double-hole end shown. By setting different numbers of pins 804 and matching clamping blocks 805, the end of the metal pipe can be processed to have different numbers of holes.

[0047] The inclination angle of the inclined protrusion 8061 is 15° to 45°. In the present embodiment, the inclination angle of the inclined protrusion 8061 is 35°. Therefore, it has been found through testing that this angle can make the inclined wedge block 806 and the clamping block 805 cooperate more smoothly.

[0048] The material conveying and cutting assembly 5 comprises a guide feeding pipe 501, a straightening mechanism 502, a pipe feeding mechanism 503, a cutting mechanism 504 and a clamping and fixing mechanism 505 which are sequentially connected and arranged along the feeding direction of the processing pipe body. The pipe feeding mechanism 503 comprises a movable die set 5031 and a fixed die set 5032 which cooperate with each other to complete the feeding. The pipe body is inserted from the guide feeding pipe 501, straightened by the straightening mechanism 502, and fed to the cutting mechanism 504 for cutting under the action of the pipe feeding mechanism 503; the clamping and fixing mechanism 505 is used to fix the cut metal pipe segment for punching by the punching assembly 3 or processing by the front pipe end processing assembly 2.

[0049] The movable die set 5031 is movable in the direction of the fixed die set 5032, and both are provided with a downward pressure cylinder. After the downward pressure cylinder of the movable die set 5031 presses the metal pipe fittings and moves toward the fixed die set 5032, the downward pressure cylinder of the fixed die set 5032 presses the metal pipe fittings, and the downward pressure cylinder of the movable die set 5031 is released and moves back to press the metal pipe fittings behind again and transport them forward, and the metal pipe fittings are transported forward through the cooperation of the movable die set 503 and the fixed die set 5032 in turn.

[0050] The machine platform 1 also includes a third support plate 9, on which the clamping and fixing mechanism 505 is fixed; the machine platform 1 is also provided with a fourth linear drive module 10, the structure and working principle of the fourth linear drive module 10 are the same as those of the third linear drive module 807, the second linear drive module 404, and the first linear drive module 203, and the fourth linear drive module 10 is connected to the third support plate 9 to drive the third support plate 9 to move, thereby controlling the clamping and fixing mechanism 505 to move closer to or further away from the cutting mechanism 504. The clamping and fixing mechanism 505 approaches the cutting mechanism 504 to clamp the metal pipe so that the cutting mechanism 504 can cut, and after cutting, the clamping and fixing mechanism 505 moves away from the cutting mechanism 504, so that the punching assembly 3 or the front pipe end processing assembly 2 can process.

[0051] like Figure 8 As shown, the straightening mechanism 502 includes an orthogonally arranged horizontal straightening roller set 5021 and a vertical straightening roller set 5022. The metal pipe is straightened under the joint action of the horizontal straightening roller set 5021 and the vertical straightening roller set 5022, which is conducive to improving the straightness.
