Description

Technical Field

[0001] The utility model relates to automatic feeding equipment for a cold drawing machine, belonging to the technical field of bearing steel pipe processing equipment. Background Art

[0002] As the main processing equipment for cold-drawn steel pipes, the cold drawing machine is used to draw ferrous and non-ferrous metal bars at room temperature and to perform secondary processing on rough pipes after hot rolling and extrusion. It is the main processing equipment for producing small-diameter, precision, thin-walled, and high-mechanical-performance pipes. Before drawing the pipe, one end of the pipe is first punched, and then the worker pushes the punched end of the steel pipe through the draft seat, and then the drawing trolley clamps the front end of the steel pipe to draw the steel pipe. During the steel pipe feeding process, due to the long length of the pipe and the certain height of the draft seat from the ground, manual feeding requires greater labor intensity, and manual calibration and drilling of the holes between the punched end of the steel pipe and the draft seat takes a lot of time, which reduces production efficiency.

[0005] Furthermore, the blocking member is slidably connected to the steel pipe conveying frame, and the position of the steel pipe is adjusted by sliding / fixing relative to the supporting part.

[0008] Furthermore, the steel pipe placement frame is provided with a swing rod driven to rotate by a driving device, and the swing rod is in contact with the upper side of the steel pipe placed on the supporting roller.

[0009] By implementing the utility model, the steel pipe is laid flat on the support part of the steel pipe conveyor rack and rolls from top to bottom. The blocking member blocks the lowest steel pipe to prevent it from rolling down from the conveyor rack. When several conveyor belts are running synchronously, during the process of the hooks on the conveyor belts conveying from a low position to a high position, the steel pipe at the lowest position is lifted and conveyed to a high position, and then falls off the hooks and onto the guide mechanism. Then, it is introduced into the limiting mechanism on the steel pipe conveyor rack, and the pushing mechanism pushes the steel pipe into the drafting seat, so as to realize the automatic feeding of the copper pipe and the calibration coordination of the cold drawing machine.

DETAILED DESCRIPTION

[0012] Embodiments of the present utility model: Figure 1As shown, an automatic feeding device for a cold drawing machine comprises a steel pipe placement rack 3 arranged between a draft seat 1 and a material ejection mechanism 2 of the cold drawing machine, and a limit mechanism for placing steel pipes is arranged on the steel pipe placement rack 3. The present application comprises a steel pipe conveying mechanism, a lifting mechanism, and a guiding mechanism. The conveying mechanism comprises a steel pipe conveying rack 4 arranged on one side of the steel pipe placement rack 3, and the steel pipe conveying rack 4 has a plurality of inclined support parts, and the support parts are the tops of the conveying rack 4, and adjacent support parts are spaced a certain distance apart. The steel pipes are laid flat on the support parts of the steel pipe conveying rack 4 and automatically roll from a high position to a low position. A stopper 5 is arranged on the steel pipe conveying rack 4, and the stopper 5 blocks the lowest steel pipe from rolling down from the steel pipe conveying rack 4; the lifting mechanism comprises a row of synchronously conveying conveyor belts 6 arranged between the steel pipe conveying rack 4 and the steel pipe placement rack 3, and the conveyor belts 6 are inclined Or vertically arranged, with hooks 7 distributed on the outer surface. When the conveyor belts 6 run synchronously, the hooks 7 on several conveyor belts 6 are on the same horizontal straight line. In the process of conveying from a low position to a high position, the steel pipe at the lowest position is lifted up and transported to a high position, and then falls off from the hooks 7 to the guide mechanism. After the steel pipe at the lowest position is lifted up, the penultimate steel pipe automatically rolls to the position blocked by the blocking member 5, and is lifted up again when the next row of hooks 7 passes by. In this way, the steel pipes are lifted one by one by the lifting mechanism. The guiding mechanism is a row of inclined guide rods 8, which guide the fallen steel pipes to the limiting mechanism on the steel pipe placement rack 3. The limiting mechanism includes several support members 9 with V-shaped tops. The steel pipes are placed on the support members 9 to support the steel pipes and limit the steel pipes on both sides. The ejecting mechanism pushes the steel pipes to move axially into the drafting seat, so as to realize the automatic feeding of the copper pipes and the calibration coordination of the cold drawing machine.

[0013] As a preferred embodiment, the blocking member 5 is slidably connected to the steel pipe conveying frame 4, and is fixed with fasteners after sliding relative to the supporting part. The position of the steel pipe is adjusted, and the distance between the lowest steel pipe and the conveyor belt 6 is adjusted according to the diameter of the conveyed steel pipe. When the conveyor belt 6 is running, the hook 7 only lifts the steel pipe in the last position each time.

[0014] As a preferred embodiment, the steel pipe conveying frame 4 is provided with a lifting mechanism 10 and supporting rollers 12 driven to rise and fall by the lifting mechanism 10. There are multiple supporting rollers 12 distributed in a straight line. The cross-section of the supporting rollers 12 is I-shaped. When the lifting mechanism 10 drives the supporting rollers 12 to rise, the steel pipe located on the support member 9 is placed on the supporting rollers 12, and the steel pipe is lifted to a height aligned with the draft seat 1 and the ejection mechanism 2. When the ejection mechanism 2 pushes the steel pipe, the supporting rollers 12 are rollingly connected with it to reduce friction. At the same time, the I-shaped supporting rollers 12 limit the two sides of the steel pipe to facilitate the calibration and matching of the steel pipe.

[0015] As a preferred embodiment, the steel pipe placement rack 3 is provided with a rocker arm 13 driven to rotate by a driving device. The rocker arm 13 is located above the support member 9 and is driven by a motor to rotate with a horizontal axis so that the bottom of the rocker arm 13 contacts the upper side of the steel pipe placed on the supporting roller 12, limiting the position of the steel pipe in the up and down directions to prevent the steel pipe from shaking up and down during transportation, so that the steel pipe can better and more accurately match with the draft seat 1.
