[0001] This utility model relates to the field of seamless steel pipe production technology, and in particular to a continuous feeding fixture for a seamless steel pipe piercing machine. Background Technology

[0002] The piercing mill in a seamless steel pipe continuous rolling production line is a crucial piece of equipment in modern industrial production. Its function is to pierce hot-rolled strip steel into seamless steel pipes. The piercing mill operates primarily through friction transmission, gradually heating the hot-rolled strip steel to the piercing temperature, and then applying high pressure to complete the piercing process. During piercing, the mill must ensure the quality of the inner and outer surfaces of the steel pipe while preventing defects such as cracks or deformation. To achieve this, the piercing mill requires high precision and stability in its structural design and operation. The piercing mill in a seamless steel pipe continuous rolling production line is an indispensable piece of equipment in modern industrial production and is widely used in fields such as petroleum, chemical, power, and construction.

[0003] Traditional feeding fixtures used in seamless steel pipe piercing machines have shortcomings: firstly, they cannot achieve continuous feeding of materials; secondly, they cannot reliably clamp the materials. Therefore, the inventors aim to optimize and improve the traditional feeding fixtures used in seamless steel pipe piercing machines. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned problems existing in the traditional technology and provide a continuous feeding fixture for a seamless steel pipe piercing machine.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A continuous feeding fixture for a seamless steel pipe piercing machine includes a lower circulating conveyor chain plate, an upper circulating conveyor chain plate, a feeding assembly, and an auxiliary clamping assembly. A horizontal conveying zone is formed between the lower and upper circulating conveyor chain plates. The right end of the lower circulating conveyor chain plate protrudes outward relative to the right end of the upper circulating conveyor chain plate, and the protruding area serves as the feeding zone. The feeding assembly is positioned above the feeding zone and is used to feed the material. A clamping plate is embedded and fixed on the outer side of each unit chain plate of the lower and upper circulating conveyor chain plates. The clamping plate has an arc-shaped slot that mates with the material. The horizontal conveying zone has a piercing station. Auxiliary clamping assemblies are symmetrically mounted on the base plates of the lower and upper circulating conveyor chain plates. Each auxiliary clamping assembly consists of a lifting push rod and a slotted clamping plate installed at its movable end. The width of the two side plates of the slotted clamping plate matches the length of the unit chain plate.

[0006] Furthermore, in the continuous feeding fixture for the seamless steel pipe piercing machine described above, the lower circulating conveyor chain plate and the upper circulating conveyor chain plate respectively drive the cyclic displacement of the unit chain plate through the cyclic movement of the chain installed on the inner side of the plate body, and the chain is driven by a drive motor to cyclically move.

[0007] Furthermore, in the continuous feeding fixture for the seamless steel pipe piercing machine described above, the lower circulating conveyor chain plate conveys in a clockwise direction, and the upper circulating conveyor chain plate conveys in a counterclockwise direction.

[0008] Furthermore, in the continuous feeding fixture for the seamless steel pipe piercing machine described above, the feeding component includes a hopper, the bottom end of which is provided with a discharge pipe, the width of which is matched with the outer diameter of the material, and the bottom end of which is provided with a baffle, the opening of which faces the horizontal conveying area.

[0009] Furthermore, in the continuous feeding fixture for the seamless steel pipe piercing machine described above, the diameter of the material to be pierced is smaller than the height of the horizontal conveying zone.

[0010] Furthermore, the continuous feeding fixture for the seamless steel pipe piercing machine mentioned above also includes a controller, which is connected to the lower circulating conveyor chain plate, the upper circulating conveyor chain plate, and the auxiliary clamping assembly.

[0011] The beneficial effects of this utility model are: 1. Achieve continuous feeding: Through the design of the lower and upper circulating conveyor chains and the cooperation of the feeding components, the parts can be continuously transported to the piercing station, solving the problem that traditional feeding fixtures cannot achieve continuous feeding of parts and improving production efficiency.

[0012] 2. Reliable clamping of materials: On the one hand, the fixed clamping plate embedded on the outer side of the unit chain plate has an arc-shaped slot, which can initially clamp the materials; on the other hand, the auxiliary clamping component set in the horizontal conveying area, which consists of a lifting push rod and a slotted clamping plate, can further reliably clamp the materials, avoid the materials from shaking or shifting during conveying and piercing, ensure the piercing quality, and solve the problem that traditional feeding tooling cannot reliably clamp the materials.

[0013] 3. Reasonable structure and ingenious coordination: A horizontal conveying area is formed between the lower and upper circulating conveyor chains, and the right end of the lower circulating conveyor chain protrudes to form a feeding area. The feeding component is set above the feeding area. The layout of each component is compact and reasonable, and they work together to realize the functions of feeding, conveying and clamping.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-5As shown, this embodiment is a continuous feeding fixture for a seamless steel pipe piercing machine, including a lower circulating conveyor chain plate 1, an upper circulating conveyor chain plate 2, a feeding assembly 3, and an auxiliary clamping assembly 4. A horizontal conveying area is formed between the lower circulating conveyor chain plate 1 and the upper circulating conveyor chain plate 2. The right end of the lower circulating conveyor chain plate 1 protrudes outward relative to the right end of the upper circulating conveyor chain plate 2, and the protruding area serves as the feeding area. The feeding assembly 3 is located above the feeding area and is used to feed the material 5. A clamping plate 102 is embedded and fixed on the outer side of the unit chain plate 101 of each of the lower circulating conveyor chain plate 1 and the upper circulating conveyor chain plate 2. The clamping plate 102 has an arc-shaped slot 103 that mates with the material 5. The horizontal conveying area is equipped with a perforation station. Auxiliary clamping components 4 are symmetrically installed on the base plates of the lower circulating conveyor chain plate 1 and the upper circulating conveyor chain plate 2. The auxiliary clamping components 4 consist of a lifting push rod 401 and a slotted clamping plate 402 installed at its movable end. The width of the two side plates of the slotted clamping plate 402 is matched with the length of the unit chain plate 101.

[0019] In this embodiment, the lower circulating conveyor chain plate 1 and the upper circulating conveyor chain plate 2 each drive the cyclic displacement of the unit chain plate 101 through the cyclic movement of the chain (not shown in the drawings for simplicity) installed on the inner side of the plate body. The chain is driven by a drive motor to cyclically move. The inner side of the unit chain plate 101 is symmetrically provided with lugs near both ends, which are used to install the chain.

[0020] In this embodiment, the lower circulating conveyor chain 1 moves clockwise, and the upper circulating conveyor chain 2 moves counterclockwise.

[0021] In this embodiment, the feeding component 3 includes a hopper 301, and a discharge pipe 302 is provided at the bottom end of the hopper 301. The width of the discharge pipe 302 is matched with the outer diameter of the material 5. A baffle 303 is provided at the bottom end of the discharge pipe 302, and the opening of the baffle 303 faces the horizontal conveying area.

[0022] In this embodiment, the diameter of the hole to be drilled in the material 5 is smaller than the height of the horizontal conveying area.

[0023] In this embodiment, a controller is also included, which is connected to the lower circulating conveyor plate 1, the upper circulating conveyor plate 2 and the auxiliary clamping assembly 4 respectively.

[0024] The working principle of this embodiment is as follows: Feeding process: The hopper 301 of the feeding assembly 3 contains the material 5, which is discharged through the bottom discharge pipe 302. The width of the discharge pipe 302 matches the outer diameter of the material 5 to ensure that the material 5 is discharged one by one. The opening of the baffle 303 at the bottom of the discharge pipe 302 faces the horizontal conveying area, and the discharged material 5 falls into the feeding area formed by the protrusion on the right end of the lower circulating conveyor chain plate 1.

[0025] Conveying process: The lower circulating conveyor chain 1 and the upper circulating conveyor chain 2 each drive the unit chain plate 101 to circulate through the circulating motion of the chain installed on the inner side of the plate (the chain is driven by a drive motor to circulate, and the inner side of the unit chain plate 101 is symmetrically provided with lugs near both ends for installing the chain). The lower circulating conveyor chain 1 conveys in a clockwise direction, and the upper circulating conveyor chain 2 conveys in a counterclockwise direction, forming a horizontal conveying zone between them. The material 5 that falls into the loading zone is conveyed to the horizontal conveying zone.

[0026] Clamping process: During the conveying process, the arc-shaped slot 103 embedded in the fixed clamping plate 102 on the outside of the unit chain plate 101 initially clamps the material 5. When the material 5 is conveyed to the perforation station in the horizontal conveying area, the auxiliary clamping assembly 4 starts to work. The lifting push rod 401 pushes the slotted clamping plate 402 installed at its movable end to descend. The width of the two side plates of the slotted clamping plate 402 matches the length of the unit chain plate 101, thereby further and reliably clamping the material 5.

[0027] Drilling Preparation: After the workpiece 5 is reliably clamped in the horizontal conveying area, it is in a suitable state for drilling. Since the diameter of the workpiece 5 to be drilled is smaller than the height of the horizontal conveying area, a suitable space is provided for the drilling operation, waiting for the drilling machine to perform the drilling operation. The entire process is controlled by the controller to coordinate the work of the lower circulating conveyor chain 1, the upper circulating conveyor chain 2, and the auxiliary clamping assembly 4, realizing automated continuous feeding and reliable clamping.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to specific implementation methods. Clearly, many modifications and variations can be made based on the content of this specification.
