Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel pipe stretching equipment, specifically to an automatic feeding and collecting device. Background Technology

[0002] Stainless steel pipe drawing equipment is a key piece of equipment used for the cold forming of stainless steel pipes. It mainly uses a coil drawing method to draw metal pipes. The drawing process of the coil drawing machine is continuous, with high linear speed and high productivity. It can provide products in coil form to the winding and packaging process. The drawing principle of the coil drawing machine is: the metal pipe is tightly wound on the outer surface of the coil in a spiral manner. The rotation of the coil pulls the pipe continuously through the drawing die, so that the pipe diameter and wall thickness meet the product requirements. It is widely used in chemical, medical device, food machinery and other fields to provide high-quality blanks or finished products for high-pressure pipelines and precision pipe fittings.

[0003] Chinese Utility Model Patent Publication No. CN 220277889 U discloses a disc drawing machine. The specification of this machine states that "a collection cart located at the bottom of the disc is provided within the frame; a protective frame is fixed to the top surface of the collection cart. By adopting the above technical solution, the collection cart at the bottom of the disc collects the pipes removed from the disc, and the protective frame protects the collected pipes, making it difficult for the pipes to slip off the collection cart during transportation." However, the collection cart lacks a corresponding limiting structure, resulting in material deviation during actual use. Furthermore, the collection cart cannot rotate synchronously with the disc, forcing the machine to only perform material feeding operations when stopped. Summary of the Invention

[0004] In view of the shortcomings of the prior art, this utility model provides an automatic feeding and collecting device to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic material collection device, comprising a main frame of a spooling machine, a drive unit, and a spool. Two symmetrically distributed guide rails are arranged below the main frame of the spooling machine. A material collection unit is arranged above the guide rails below the main frame of the spooling machine. An inner fixing plate is fixedly installed inside the spool. An auxiliary transmission unit is fixedly installed on the inner side of the spool through the inner fixing plate. A spooling machine drawing die is arranged on the front side of the main frame of the spooling machine. A clamping unit and a cutting unit are arranged on the inner side of the spool. A limiting seat is fixedly installed on the upper part of the guide rails.

[0006] Preferably, the auxiliary transmission unit includes a first mounting plate, which is fixedly connected to an inner fixed plate. A second mounting plate is fixedly mounted on the side of the first mounting plate away from the inner fixed plate. A bracket and a guide seat are fixedly mounted on both ends of the side of the second mounting plate away from the first mounting plate, respectively. A cylinder is fixedly mounted on the outer side of the bracket, and a limit rod is fixedly mounted on the movable end of the cylinder. The material collection unit includes a main frame, a sub-frame fixedly installed at the bottom of the main frame, rollers fixedly installed at the four corners of the lower part of the sub-frame, a pin seat fixedly installed on the outer side of the sub-frame, a lever groove opened on the outer side of the pin seat, a pin rod inserted into the inside of the pin seat, a horizontal lever threadedly connected to the outer side of the pin rod, a turntable provided on the upper part of the main frame, a rotating rod fixedly installed on the lower part of the turntable, a fixing sleeve fixedly installed on the inner side of the main frame, an outer receiving rack and an inner receiving rack fixedly installed on the upper part of the turntable, and a limit plate fixedly installed on the top of the turntable.

[0007] The above technical solution can drive the material collection unit to rotate. During operation, the moving end of the cylinder pushes the limit rod downward. During the stretching of the stainless steel tube, the drive unit can drive the disc to rotate. The disc can drive the outer and inner receiving frames to rotate synchronously through the inner auxiliary transmission unit. After stretching is completed, the material is cut and discharged by the cutting unit. The stainless steel coil can automatically fall between the outer and inner receiving frames, realizing automatic discharge without manual operation.

[0008] Preferably, there are two identical auxiliary transmission units, which are diagonally distributed about the center line of the disc cylinder. The limiting rod is slidably connected to the guide seat, and the limiting rod passes through the guide seat and extends to the outside of the guide seat.

[0009] The above technical solution ensures that the auxiliary transmission unit can make the material collection unit rotate synchronously during the stretching process of the stainless steel tube, which facilitates the subsequent material unloading after the stretching is completed.

[0010] Preferably, the centers of the main frame and the sub-frame are located on the same vertical line, the outer receiving rack and the inner receiving rack are in a ring structure, and two identical limiting plates are provided, with the two limiting plates being diagonally distributed about the center line of the turntable.

[0011] Preferably, the number of limiting rods and limiting plates are the same, and the limiting rods and limiting plates are in an abutting connection.

[0012] The above technical solution ensures accurate material feeding by using diagonally distributed limiting plates and corresponding limiting rods.

[0013] Preferably, the horizontal lever and the lever groove are slidably connected, the rotating rod and the fixed sleeve are rotatably connected, a bearing is provided at the connection between the rotating rod and the fixed sleeve, and two identical pin seats, pin rods and horizontal levers are provided, and the two pin seats, pin rods and horizontal levers are symmetrically distributed on the outside of the main frame.

[0014] With the above technical solution, after the material collection unit moves to the designated position below the disc, the horizontal lever drives the pin rod to insert into the reserved limiting hole on the guide rail, which can limit the material collection unit and prevent the material collection unit from shifting during the stretching of the stainless steel tube.

[0015] Preferably, two identical limiting seats are provided, and the two limiting seats are in contact with the roller at the lower part of the sub-frame away from the pin rod.

[0016] The above technical solution, through the design of the limiting seat and the roller contacting each other, can further limit the material collection unit and effectively prevent the material collection unit from shifting during the stretching of the stainless steel pipe.

[0017] Compared with the prior art, the present invention provides an automatic material feeding and collection device, which has the following beneficial effects: 1. This automatic feeding and collecting device achieves efficient automatic feeding through the setting of an auxiliary transmission unit and a feeding and collecting unit. The diagonally distributed limit rods and limit plates in the auxiliary transmission unit work precisely to ensure that the feeding and collecting unit rotates synchronously with the drum. After the stainless steel coil is cut by the cutting unit, it can automatically fall between the outer and inner receiving racks. No manual intervention is required throughout the process, which greatly improves feeding efficiency, reduces manual operation intensity, and can also achieve feeding without stopping the machine. 2. This automatic material collection device adopts a double limiting structure to ensure operational stability. On the one hand, it is fixed by inserting a pin into the guide rail limiting hole. On the other hand, the limiting seat and roller abut against each other to strengthen the limiting, effectively preventing the material collection unit from shifting during the stretching process, ensuring the accuracy of the material feeding position, and the overall operation is simple.

The first mounting plate 701 is fixedly connected to the inner fixing plate 6. A second mounting plate 702 is fixedly mounted on the side of the first mounting plate 701 away from the inner fixing plate 6. A bracket 703 and a guide seat 705 are fixedly mounted on both ends of the side of the second mounting plate 702 away from the first mounting plate 701, respectively. A cylinder 704 is fixedly mounted on the outer side of the bracket 703. A limit rod 706 is fixedly mounted on the movable end of the cylinder 704.

[0023] Specifically, two identical auxiliary transmission units 7 are provided, and the two auxiliary transmission units 7 are diagonally distributed about the center line of the disc 3.

The advantage is that it can drive the material collection unit 8 to rotate. During operation, the movable end of the cylinder 704 pushes the limit rod 706 downward. During the stretching of the stainless steel tube, the drive unit 2 can drive the disc 3 to rotate. The disc 3 can drive the outer receiving frame 807 and the inner receiving frame 808 to rotate synchronously through the inner auxiliary transmission unit 7. After the stretching is completed, the material is cut by the cutting unit 11 and discharged. The stainless steel coil can automatically fall between the outer receiving frame 807 and the inner receiving frame 808, which can realize automatic discharge without manual operation.

[0025] Specifically, the centers of the main frame 801 and the secondary frame 802 are located on the same vertical line, the outer receiving rack 807 and the inner receiving rack 808 are in a ring structure, and two identical limiting plates 809 are provided, with the two limiting plates 809 being diagonally distributed about the center line of the turntable 804.

[0026] Specifically, the number of limiting rods 706 and limiting plates 809 is the same, and the limiting rods 706 and limiting plates 809 are in abutting connection. The advantage is that the diagonally distributed limiting plates 809 correspond to the limiting rods 706, ensuring accurate material feeding.

The advantage is that after the material collection unit 8 moves to the designated position below the disc 3, the horizontal lever 813 drives the pin rod 811 to insert into the reserved limiting hole on the guide rail 9, which can limit the material collection unit 8 and prevent the material collection unit 8 from shifting during the stretching of the stainless steel tube.

[0028] Specifically, two identical limiting seats 10 are provided, and the two limiting seats 10 are in abutting connection with the roller 803 at the lower end of the sub-frame 802 away from the pin rod 811. The advantage is that the abutting connection between the limiting seat 10 and the roller 803 can further limit the material collection unit 8, effectively preventing the material collection unit 8 from shifting during the stretching of the stainless steel tube.

[0029] Working principle: In use, the operator first pushes the material collection unit 8 to below the disc 3 until the limiting seat 10 abuts against the roller 803. Then, the horizontal lever 813 drives the pin 811 to insert into the pre-reserved limiting hole on the guide rail 9. After the material collection unit 8 is fully limited, the auxiliary transmission unit 7 is activated. The movable end of the cylinder 704 pushes the limiting rod 706 downward.

The outer receiving rack 807 and inner receiving rack 808 on the material collection unit 8 rotate synchronously with the drum 3. After the stainless steel coil is stretched, the cutting unit 11 cuts the material head. The cut stainless steel coil automatically falls between the outer receiving rack 807 and the inner receiving rack 808, which can realize automatic material feeding. Then, under the limit guidance of the lever 812 through the horizontal lever 813, it returns to the initial state. Then, the material collection unit 8 is moved out from under the drum 3. The operation is simple, practical and convenient, and can realize material feeding without stopping the machine.
