Description

Technical Field

[0002] At present, the machinery industry uses cutting machines to cut pipes to mass-produce pipes of specific lengths. In order to achieve the purpose of continuous cutting, it is usually done by manually assisting in material division and then using simple mechanical equipment to load the pipes one by one.

The second rack 224 is fixed to the edge of the loading plate 203 away from the tube material loading side and is parallel to the edge of the adjusting plate 202 close to the tube material loading side.

Thus, batches of pipe materials are placed on the pipe material warehouse rack 100 so that the strip 301 is located below the batch of pipe materials. When the loading plate 203 drops to the lowest point and the pipe materials have not yet fallen into the material dividing port A, the strip 301 is retracted by rotating the reel 302.

[0069] The material dividing and feeding automation process of the tube material dividing mechanism 200 is as follows: if the feeding plate 203 is in a high position, the second linear drive component 209 first drives the feeding plate 203 to descend rapidly; when the first sensor switch 211 senses that the upper end of the plate edge of the feeding plate 203 close to the tube material feeding side is pressed against the tube material, the second linear drive component 209 drives the feeding plate 203 to decelerate and descend slowly, and at the same time, the first linear drive component 208 drives the feeding plate 203 to extend outward until the second sensor switch 212 senses that the tube material falls onto the material dividing bayonet A, at which time the feeding plate 203 stops extending outward, and the second linear drive component 209 drives the feeding plate 203 to rapidly The third linear drive assembly 209 drives the loading plate 203 to decelerate and slowly rise until the fourth induction switch 214 senses that the tube material falls onto the receiving port B. The second linear drive assembly 209 drives the loading plate 203 to descend rapidly and enter the next cycle. At the same time, the third linear drive assembly drives the ejecting plate 204 to eject the tube material on the receiving port B to the tube feeding device, thereby completing the entire tube material sorting and feeding automation process.

The fifth induction switch 217 is electrically connected to the control circuit of the push cylinder 216. The push cylinder is preferably a double push rod cylinder. When the fifth induction switch 217 senses whether there is stacked material on the material dividing port A, the pushing cylinder 216 drives the pushing plate 215 to push the stacked material on the material dividing port A back into the pipe material storage rack 100, ensuring that the pipe materials can be loaded one by one in an orderly manner.

[0076] The working process of the material transfer and centering mechanism 600 is as follows: the fifth linear drive component 609 drives the material transfer movable seat 602 to move backward, and the sixth linear drive component 610 drives the material transfer support plate 603 to move downward until the material transfer support plate 603 is located below the first pipe material near the limit block 504, the sixth linear drive component 610 drives the material transfer support plate 603 to move upward and lifts up the first pipe material near the limit block 504, so that the pipe material is higher than the limit block 504, and then the fifth linear drive component 609 drives the material transfer movable seat 602 to move forward; when the pipe material moves to the top of the tube placement seat 503, the sixth linear drive component 610 drives the material transfer support plate 603 to move downward, and places the pipe material on the material transfer support plate 603 on the tube placement seat 503, and then the seventh linear drive component 611 drives the centering movable seat 604 to move upward, and uses the transverse centering fixture 605 to perform transverse centering positioning on the pipe material.

The seventh linear drive component 611 is a third material transfer cylinder, which is vertically fixed on the material transfer movable seat 602, and the push rod of the third material transfer cylinder faces upward and is connected to the centering movable seat 604. It should be noted that when the first material transfer cylinder, the second material transfer cylinder and the third material transfer cylinder are double push rod cylinders, the corresponding linear guide pair settings can be cancelled.

[0078] Furthermore, the transfer fixing base plate is provided with a sixth induction switch 619 at one end away from the material discharging direction, and is preferably a contact induction switch. When the sixth induction switch 619 senses that the transfer moving seat 602 has moved back to a position, the fifth linear drive assembly 609 stops, and the sixth linear drive assembly 610 drives the transfer supporting plate 603 to move upward and lift up the first pipe material close to the limit block 504.

When the pipe material on the pipe placing seat 503 moves to the clamping position of the vertical centering fixture 703, the vertical centering fixture 703 is used to vertically center the pipe material and keep the clamping state. Then the eighth linear drive assembly continues to drive the feeding movable seat 702 to move forward and deliver the pipe material to the next device (such as: pipe material cutting device).

The clamping cylinder 715 is fixed on the vertical centering base 711, and the push rod of the clamping cylinder 715 is connected to the movable base of the lower clamping plate 713 through a connecting arm.
