Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing equipment, and in particular discloses a multi-step integrated forming processing equipment for a tee prefabricated part. Background Art

[0002] The existing tee prefabricated parts need to go through four processing steps during the processing. The first step is to use punching equipment to punch an elliptical hole in the center of the pipe fitting. Then, based on the elliptical hole, the elliptical hole is heated to increase its temperature. Then, the elliptical hole is processed into a circular end tube protruding outward using a hole expansion and stretching device. Then, the circular end tube is cut using a cutting device to make its end face smooth. Finally, the burrs at the cut are removed using a grinding device.

[0003] From the above-mentioned existing processing process of the tee prefabricated parts, it can be seen that at least four sets of equipment are required to complete the processing of the tee prefabricated parts, namely punching, hole expansion and stretching, cutting and polishing. The entire processing process of the tee prefabricated parts not only greatly increases the cost of the processing equipment, but also requires the transfer of the blank after each processing step is completed, thereby seriously reducing the processing efficiency of the tee prefabricated parts. Therefore, in view of the deficiency that the existing tee prefabricated parts need to be equipped with four sets of equipment, namely punching, hole expansion and stretching, cutting and polishing, to complete the processing of the tee prefabricated parts, the present application designs a processing equipment that can realize the above-mentioned processing steps of the tee prefabricated parts in an integrated manner, so as to solve the shortcomings of the existing tee prefabricated parts processing equipment, namely high cost and low processing efficiency.

[0009] As a specific arrangement of the above scheme, the clamp comprises a lower clamp fixed on the upper surface of the clamp machine table, a top plate is connected to the clamp machine table through a plurality of upright columns, the top plate is provided with a first telescopic driving element, the lower end of the first telescopic driving element is connected with an upper clamp, and the upper clamp is arranged in alignment with the lower clamp.

[0010] As a further arrangement of the above scheme, the upper clamp is connected with a vertical guide sliding rod, and the top plate is provided with a guide sliding hole matched with the guide sliding rod.

[0011] As a specific arrangement of the above scheme, the upper surface of the processing seat machine table is provided with a transverse sliding rail, the moving seat is arranged on the transverse sliding rail, the side end of the processing seat machine table is provided with a fourth telescopic driving element, and the end of the fourth telescopic driving element is connected with the moving seat.

[0014] The disclosed tee preform multi-process integrated molding processing equipment utilizes a fixture to clamp and secure the pipe fitting in a positioning slot during the process of processing the pipe fitting into the tee preform, while simultaneously placing a steel ball at the end of the positioning slot near the second push rod. Next, the movable base is moved left and right to align the punching die base with the notch on the fixture. After alignment, the punching die base is moved toward the pipe fitting using a fifth telescopic drive member. The punching die head is then used to pre-open an elliptical hole in the pipe fitting.

Then, the second push rod pushes the steel ball into the other end of the pipe. When the steel ball reaches the oval hole, its other end is restrained by the first push rod. Then, as the second push rod continues to push, the inclined groove pushes the steel ball toward the oval hole. The squeezing effect of the steel ball realizes the expansion and stretching process of the heated oval hole, until the steel ball is squeezed out of the pipe.

It not only achieves the hole-opening effect, but also makes the circular hole pull out a certain distance of the pipe wall during the process of the pipe fitting after the steel ball is squeezed and softened. The pipe wall can be directly connected to the pipe fitting to form a tee pipe after hole expansion, leveling and polishing, making the preparation process of the entire tee pipe simpler; the design of the entire tee prefabricated part processing equipment reduces the processing steps of the tee prefabricated part, reduces the equipment cost and processing cost, and has extremely high economic value.

[0029] Positioning grooves 301 matching the pipe fittings are provided on opposing sides of the lower fixture 3 and the upper fixture 7. Positioning grooves 301 extend through the left and right ends of the positioning grooves 301. Furthermore, notches 302 facing the processing base 2 are provided at the centers of the lower fixture 3 and the upper fixture 7. During the processing of the tee preform, the operator places the pipe fitting in the positioning groove 301 and then places a steel ball 303 at one end of the positioning groove 301.

[0030] A second telescopic drive member 8 and a third telescopic drive member 9 are fixedly mounted on the fixture platform 1 on either side of the lower fixture 3.

A bevel groove is further defined at the end of the second push rod 901, and the bevel groove is positioned toward the side of the notch 302.

[0031] Reference Attachment Figure 4 and attached Figure 5 Two transverse slide rails 10 are provided on the upper surface of the processing base machine table 2, and a moving seat 11 is slidably provided on the two transverse slide rails 10. At the same time, a fourth telescopic driving member 12 is provided at the left end of the processing base machine table 2, and the telescopic end of the fourth telescopic driving member 12 is connected to the moving seat 11, so that the moving seat 11 can move left and right along the transverse slide rail 10 under the action of the fourth telescopic driving member 12, thereby adjusting the position of the moving seat 11.

[0032] Three longitudinal slide rails 13 are arranged at intervals on the upper surface of the movable base 11, and a punching die base 14, a reaming die base 15 and a grinder base 16 are arranged on the three longitudinal slide rails 13 in sequence from left to right. An elliptical punching die head 141 is arranged on the end face of the punching die base 14 facing the fixture machine 1, and a stepped reaming die head 151 is arranged on the end face of the reaming die base 15 facing the fixture machine 1. A grinding motor 161 is installed inside the grinder base 16, and a grinding wheel 162 extending out of the grinder base 16 and facing the fixture machine 1 is arranged on the motor shaft of the grinding motor 161.

[0033] Bumps 17 are welded to the upper surfaces of the punching die base 14, the reaming die base 15, and the grinder base 16. At the same time, a side plate 18 is provided on the upper surface of the processing base 2 away from the fixture base 1. A fifth telescopic drive member 19 is mounted on the side plate 18, and the fifth telescopic drive member 19 is aligned with the notch 302 on the lower fixture 3. A U-shaped block 20 is connected to the end of the piston rod of the fifth telescopic drive member 19. When the punching die base 14, the reaming die base 15, or the grinder base 16 moves to align with the fifth telescopic drive member 19, the U-shaped block 20 will be stuck on the corresponding bump 17. Then, starting the fifth telescopic drive member 19 can realize the forward and backward movement of the punching die base 14, the reaming die base 15, or the grinder base 16.

[0034] Finally, it should be noted that in this embodiment, the first telescopic drive member 6, the second telescopic drive member 8, the third telescopic drive member 9, the fourth telescopic drive member 12, and the fifth telescopic drive member 19 can be either pneumatic cylinders or hydraulic cylinders. Among them, the third telescopic drive member 9 is preferably a hydraulic cylinder.

[0035] During the preparation of a tee preform using the multi-step integrated molding process disclosed in Example 1, an operator places a pipe fitting in the positioning groove 301 of the lower fixture 3 and simultaneously places a steel ball 303 at one end of the positioning groove 301. Next, the operator activates the first telescopic drive member 6 to bring the upper fixture 7 into contact with the upper surface of the lower fixture 3, thereby clamping and securing the pipe fitting in the positioning groove 301.

[0036] Subsequently, the fourth telescopic drive member 12 is activated to move the movable seat 11 left and right, thereby aligning the punching die base 14 with the notch 302 on the lower fixture 3, and then the fifth telescopic drive member 19 is activated to move the punching die base 14 along the longitudinal slide rail 13 toward the notch 302, and an elliptical hole is processed on the pipe fitting through the punching die head 141. Next, the second telescopic drive member 8 is first activated to extend the end of the first push rod 801 to the position of the elliptical hole inside the pipe fitting, and then the third telescopic drive member 9 is activated to allow the second push rod 901 to push the steel ball 303 and extend it into the interior of the pipe fitting. When the steel ball 303 reaches the position of the elliptical hole, one side is restricted by the end of the first push rod 801, while the other end is squeezed by the inclined groove at the end of the second push rod 901, thereby forcing the steel ball 303 to be squeezed out of the elliptical hole of the pipe fitting, thereby realizing the expansion and stretching process of the elliptical hole.

[0037] When the steel ball 303 is completely squeezed out of the elliptical hole, the fourth telescopic driving member 12 is started to move the movable seat 11 left and right, thereby aligning the hole expansion die base 15 with the notch 302 on the lower clamp 3, and then the fifth telescopic driving member 19 is started to move the hole expansion die base 15 along the longitudinal slide rail 13 toward the notch 302, and the circular hole squeezed out by the steel ball 303 is expanded and shaped through the stepped hole expansion die head 151.

[0038] Finally, continue to start the fourth telescopic drive member 12 to move the movable base 11 left and right, thereby aligning the grinder base 16 with the notch 302 on the lower clamp 3. After the alignment is completed, start the grinding motor 161 to rotate the grinding wheel 162 at high speed, and then start the fifth telescopic drive member 19 to move the grinder base 16 along the longitudinal slide rail 13 toward the notch 302 until the high-speed rotating grinding wheel 162 contacts the end face of the circular hole on the pipe fitting. The grinding wheel 162 can be used to level and grind the circular hole port. Example 1

[0039] Example 2 discloses a three-way prefabricated multi-process integrated molding processing equipment that is improved based on the technical solution in Example 1. The similarities between Example 2 and Example 1 are not described again. The difference is that a heating component is provided above the punching die 14 to heat the elliptical hole position on the pipe. Figure 4 , Attachment Figure 5 and attached Figure 6 Describe it in detail.

[0040] The heating assembly in this embodiment 2 is shown in the attached Figure 6The device comprises a bevel frame 21 fixedly mounted on the upper surface of the punching die base 14. The bevel frame 21 is provided with an inclined slide rail 22 inclined downwardly toward the fixture platform 1. A heater 23 is slidably mounted on the inclined slide rail 22. The lower end of the heater 23 is connected to an induction heating coil 24 disposed toward the fixture platform 1. A sixth telescopic drive member 25 is fixedly mounted on the upper end of the bevel frame 21, and the end of the sixth telescopic drive member 25 is connected to the heater 23. The design of the above-mentioned heating assembly is such that after the punching die 141 completes the processing of the elliptical hole on the pipe fitting, the sixth telescopic drive member 25 is used to push the heater 23 downwardly, so that the induction heating coil 24 is aligned with the position of the elliptical hole. The induction heating coil 24 is used to rapidly heat the pipe fitting at the position of the elliptical hole, thereby softening the pipe fitting at the position of the elliptical hole. After the temperature is increased and softened, the pipe fitting is then squeezed by the steel ball 303 to achieve the process of expanding and drawing the elliptical hole.

[0041] Finally, this embodiment 2 further includes an ejector pin (not shown) in the lower fixture 3, the upper end of which extends into the lower end of the positioning groove 301. This ejector pin design allows the tee preform to be processed and, when the upper fixture 7 moves upward and separates from the lower fixture 3, the ejector pin to extend from the lower end of the positioning groove 301, thereby ejecting the tee preform from the positioning groove 301 and achieving an automatic unloading effect.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
