Description

Technical Field

[0001] The invention relates to the field of metal pipe processing technology innovation, and in particular to a processing device suitable for reducing the tip of a pipe end. Background Art

[0002] The taper tube shrinking machine is also called a closing machine or a beveling machine. It is a device used to shrink the end of a round tube into a cone shape. It shrinks the tube diameter and mouth shape according to a certain cone angle. With the corresponding mold, metal tubes of different diameters can be processed to meet different needs. With the corresponding mold, conical workpieces of different sizes can be processed, and the conical tube is bright and smooth. Therefore, this equipment is widely used in bicycles, electric vehicle frame pipe fittings, metal furniture industry, iron art guardrail industry, etc.

[0003] The tube shrinking machines on the market generally complete the loading operation manually. During the tube shrinking process, in order to prevent damage to the tube and the tube shrinking machine, the end of the tube is generally required to be heated before being placed in the tube shrinking machine. After the end is completely red hot, it is inserted into the tube shrinking machine for taper processing. The tube shrinking machine uses the tube shrinking motor as a power source to allow the mold to continuously hammer the outer side of the red hot end of the tube to achieve taper processing, which is the same principle as metal forging.

[0004] However, the efficiency of manual loading is low, and the heat transfer of metal pipes is strong, resulting in a high overall temperature after the end of the pipe is heated. It is difficult for operators to move to the shrinking machine and they are prone to burns. If a robot is used for clamping, not only is the design cost of the robot high, but it also needs to be reset after each step is completed, resulting in room for improvement in processing efficiency.

[0005] The prior art (announcement number: CN209021095U, announcement date: 2019.06.25) discloses a fully automatic processing equipment for shrinking the front end of an advanced small catheter, which inserts the front end of the advanced small catheter into the high-frequency heating coil to realize high-frequency induction heating of the front end of the advanced small catheter; since the high-frequency heating coil is located on the axis of the rotating mold cavity of the tube shrinking machine, the clamping and feeding part can clamp the advanced small catheter that has completed the front end heating and move it forward so that its front end enters the rotating spinning mold of the tube shrinking machine part for taper processing. After the processing is completed, it is necessary to withdraw the rotating mold cavity and the high-frequency heating coil, and manually replace the next unprocessed catheter, and generally it needs to cool down for a period of time before it can be manually replaced, resulting in low production efficiency.

[0006] In addition, after the end of the metal pipe is tapered, some products need to be drilled at the tapered position. For example, the existing solar ground piles are in the shape of a pipe as a whole, with the top end tapered and holes drilled on the tapered surface. The current common method is to wait for it to cool before drilling. However, this drilling method is not only inefficient, but also the metal is relatively soft when it is red-hot, so it is easier to drill holes at this time. Therefore, the present invention proposes a processing equipment suitable for the tapered end of the pipe to solve the various problems mentioned above. Summary of the invention

[0048] The principle is: during operation, the pipes 8 to be processed are stacked in the feeding mechanism 2, and the feeding mechanism 2 will drive the pipes 8 to be transported one by one to the two side plates 6 on the right side of the heating mechanism 3. At this time, the heating mechanism 3 will be inserted into the end of the pipe 8 for heating, so that the end of the pipe 8 is burned red, and then the pipe 8 will roll to the right side of the tube shrinking mechanism 4 along the slope 7 on the side plate 6, and the pipe 8 can be pushed into the tube shrinking mechanism 4 for tube shrinking processing, and then the red-hot end of the pipe 8 is processed into a conical structure, and then the pipe 8 exits the tube shrinking mechanism 4, and the pipe 8 continues to roll forward along the slope 7 of the side plate 6.

The pipe 8 on the upper edge of the support frame 2.6 rolls onto the at least two temporary mechanisms 2.8 through the inclined protrusions 2.7; when the pipe 8 is transported to the support frame 2.6, the pipe 8 will roll onto the temporary mechanism 2.8 through the inclined protrusions 2.7 for temporary positioning. When the previous pipe 8 is heated and begins to be transported to the right side of the tube shrinking mechanism 4 for tube shrinking operation, the pipe 8 on the temporary mechanism 2.8 will roll onto the two side plates 6 on the right side of the heating mechanism 3, thereby achieving the effect of automatic feeding and heating.

[0055] As a further solution of the present invention: two side plates 6 on the right side of the tube shrinking mechanism 4 are fixedly installed with limit clamps 14, the limit clamps 14 include a front clamp 14.1, a rear clamp 14.2 and a bottom plate 14.3, the bottom sides of the front clamp 14.1 and the rear clamp 14.2 are formed with gears 14.4, the gears 14.4 are meshed with racks 14.5, the two racks 14.5 are staggered left and right, and two translation hydraulic cylinders 14.6 are fixedly installed on the bottom plate 14.3, the translation hydraulic cylinders 14. 6 drives the rack 14.5 to move forward and backward; when the pipe 8 rolls down to the right side of the tube shrinking mechanism 4, the rear clamp 14.2 is in an open state and the front clamp 14.1 is in a closed state. At this time, the pipe 8 will roll down to the front clamp 14.1 of the two limit clamps 14 to achieve positioning, and then the rear clamp 14.2 is driven to clamp by the translation hydraulic cylinder 14.6 to achieve accurate positioning of the pipe 8. After the tube shrinking process is completed, the front clamp 14.1 is opened to allow the pipe 8 to roll down to the right side of the punching mechanism 5 along the inclination 7 of the side plate 6.

[0056] As a further solution of the present invention: a second slide rail 15 is fixedly installed on the frame 1, a second slider 16 is fixedly installed on the bottom side of the right bottom plate 14.3, the second slider 16 is slidably mounted on the second slide rail 15, and a tube shrinking and pushing hydraulic cylinder 17 is fixedly installed on the frame 1, the tube shrinking and pushing hydraulic cylinder 17 drives the bottom plate 14.3 on the right to move left and right along the second slide rail 15; during the tube shrinking processing, the tube shrinking and pushing hydraulic cylinder 17 can be used to drive the right limit clamp 14 to move to the left, the limit clamp 14 will clamp the pipe 8 and transport it to the tube shrinking mechanism 4 for tube shrinking processing, thereby achieving the effect of automatic tube conveying and shrinking, and at the same time it can be suitable for pipes 8 of any length, thereby meeting the processing of 1.2 meters to 6 meters of pipes 8.

[0057] As a further solution of the present invention: a base 22 is fixedly installed on the bottom plate 14.3 of the right side limit clamp 14, and a material equalization plate 23 is arranged on the base 22, and the material equalization plate 23 is located on the right side of the pipe 8. The pipe shrinking pushing hydraulic cylinder 17 pushes the pipe 8 into the pipe shrinking mechanism 4 through the base 22, the material equalization plate 23 and the right side limit clamp 14 for pipe shrinking processing.

[0058] As a further solution of the present invention: two tube-reducing and pushing hydraulic cylinders 17 are provided, and the telescopic rods of the two tube-reducing and pushing hydraulic cylinders 17 are respectively fixedly installed on the left and right sides of the right bottom plate 14.3; the force for conveying the tube 8 into the tube-reducing mechanism 4 is more uniform and stable, and stable pushing is achieved, so that a more precise conical surface can be processed at the end of the tube 8.

[0059] As a further solution of the present invention: the clamping force of the left limit clamp 14 is smaller than that of the right limit clamp 14. When the tube shrinking and pushing hydraulic cylinder 17 drives the right bottom plate 14.3 to move to the left, the right limit clamp 14 clamps the tube 8 and transports it to the tube shrinking mechanism 4 for taper processing; the left limit clamp 14 only plays a limiting role. In the process of pushing the tube 8 into the tube shrinking mechanism 4 for taper processing, only the right limit clamp 14 is used to clamp the tube 8, so as to achieve the effect of rapid positioning and pushing.

[0060] As a further solution of the present invention: the tube shrinking mechanism 4 includes a shell 4.1, a tube shrinking mold cavity 4.2 and a tube shrinking motor 4.3. The shell 4.1 and the tube shrinking motor 4.3 are both fixedly mounted on the frame 1. The tube shrinking mold cavity 4.2 is rotatably mounted in the shell 4.1. The tube shrinking motor 4.3 drives the tube shrinking mold cavity 4.2 to rotate.
