Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of square steel processing, and particularly relates to a cold-drawn square steel pipe head processing device. Background Technique
[0002] Square steel is solid steel, which is different from hollow square pipes. In the process of cold-drawing steel pipes, in order to facilitate the steel pipes to enter the forming die, the pipe heads of the steel pipes will be hammered flat or pointed first. After the cold-drawing of the steel pipes is completed, this deformed part of the pipe heads of the steel pipes needs to be cut off.
[0003] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology: The current processing device for cutting the square steel pipe head usually does not detect the levelness of the square steel before cutting work, resulting in a non-vertical (but "tilted") cross-section after the cutting knife cuts the square steel pipe head, thus causing inaccurate cutting positions.
[0004] Therefore, we propose a cold-drawn square steel pipe head processing device to solve the above problems. Content of the Utility Model
[0005] The main purpose of the present utility model is to provide a cold-drawn square steel pipe head processing device, which only cuts when the square steel is in a horizontal state, thereby ensuring that the cross-section after cutting the square steel pipe head is vertical and ensuring the accuracy of the cutting position, and can effectively solve the problems in the background technique.
[0006] In order to achieve the above purpose, the present utility model adopts the following technical scheme:
[0007] A cold-drawn square steel pipe head processing device includes a base and a processing mechanism located on the base. A convex seat is welded on the base, and a pipe placing groove for placing square steel is formed on the convex seat. A receiving frame is welded on the top wall of the base above the convex seat. Among them, a plurality of infrared distance sensors are installed on the bottom wall of the receiving frame, and a controller is installed on the top wall of the receiving frame;
[0008] A support is welded on one side of the top wall of the base. A first motor is horizontally installed on one side wall of the support. A bottom groove is formed on the bottom wall of the support. A screw rod, a limiting rod and an upper sliding seat are arranged in the bottom groove. Among them, the output shaft of the first motor is coaxially connected with the screw rod. Both sides of the limiting rod are welded to the support. The upper sliding seat is threadedly sleeved on the screw rod and slidably sleeved on the limiting rod;
[0009] The processing mechanism includes a vertical plate welded to the bottom wall of the upper sliding seat, a second motor horizontally installed on one side wall of the vertical plate, and a cutting knife coaxially connected to the output shaft of the second motor. The infrared distance sensors, the first motor and the second motor are all electrically connected to the controller. All the electrical facilities on the base need to be powered by an external power source.
[0010] As a preferred embodiment, through slots are formed on both opposite side walls of the receiving frame; the two through slots provided are for square steel to pass through.
[0011] As a preferred embodiment, multiple infrared distance sensors are evenly distributed on the receiving frame in the horizontal direction; thus, the square steel can be detected from different positions to determine its levelness.
[0012] As a preferred embodiment, both sides of the screw rod are rotatably connected to the support, and the screw rod is parallel to the limit rod; enabling the screw rod to operate stably under the drive of the first motor.
[0013] As a preferred embodiment, the second motor and the cutting knife are distributed on both sides of the vertical plate, and the cutting knife is vertically arranged; enabling the cutting knife to cut the pipe head of the square steel passing through the pipe placement groove.
[0014] In summary, the technical effects and advantages of the present utility model are as follows:
[0015] For this cold-drawn square steel pipe head processing device, the distances between the multiple infrared distance sensors on the square steel pipe head and the square steel pipe head are detected. When the values of the multiple distances are the same (or within the error range), it indicates that the square steel pipe head is kept horizontal. At this time, the controller will drive the two motors to operate to cut the square steel pipe head, thereby ensuring the accuracy of the cutting position of the square steel pipe head;

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Referring to Figures 1 - 4 , a cold-drawn square steel pipe head processing device includes a base 1 and a processing mechanism located on the base 1. A protruding seat 2 is welded on the base 1, and a pipe placement groove 3 for placing square steel is formed on the protruding seat 2. A receiving frame 4 is welded on the top wall of the base 1 above the protruding seat 2. Penetration grooves 5 are formed on both opposite side walls of the receiving frame 4. The two penetration grooves 5 provided are for the square steel to pass through. A plurality of infrared distance sensors 6 are installed on the bottom wall of the receiving frame 4. The plurality of infrared distance sensors 6 are evenly distributed along the horizontal direction on the receiving frame 4, so as to detect the square steel from different positions to determine its levelness. A controller 7 is installed on the top wall of the receiving frame 4;
[0024] A bracket 8 is welded on one side of the top wall of the base 1. A first motor 9 is horizontally installed on one side wall of the bracket 8. A bottom groove 10 is formed on the bottom wall of the bracket 8. A screw 11, a limit rod 12 and an upper sliding seat 13 are provided in the bottom groove 10. The output shaft of the first motor 9 is coaxially connected to the screw 11. Both sides of the limit rod 12 are welded to the bracket 8. Both sides of the screw 11 are rotatably connected to the bracket 8, and the screw 11 and the limit rod 12 are parallel to each other, so that the screw 11 can operate stably under the drive of the first motor 9. The upper sliding seat 13 is threadedly sleeved on the screw 11, and the upper sliding seat 13 is slidably sleeved on the limit rod 12;
[0025] The processing mechanism includes a vertical plate 14 welded to the bottom wall of the upper sliding seat 13, a second motor 15 horizontally installed on one side wall of the vertical plate 14, and a cutting knife 16 coaxially connected to the output shaft of the second motor 15. The second motor 15 and the cutting knife 16 are distributed on both sides of the vertical plate 14, and the cutting knife 16 is vertically arranged, so that the cutting knife 16 can cut the pipe head of the square steel passing through the pipe placement groove 3. The infrared distance sensors 6, the first motor 9 and the second motor 15 are all electrically connected to the controller 7. The infrared distance sensors 6 can refer to the technical principle of the E3Z-T61 model, and the controller 7 can refer to the technical principle of the S7-200 model. All the power facilities on the base 1 need to be powered by an external power source.
[0026] The cold-drawn square steel pipe end processing device: First, insert the square steel into the device from the side of the convex seat 2 facing away from the bracket 8, so that the square steel passes through a penetration slot 5 on the receiving frame 4 and enters the pipe placement slot 3, and then passes through another penetration slot 5 (the penetration slot 5 close to the bracket 8) and exits. The pipe end of the square steel is placed inside the bracket 8. Subsequently, a plurality of infrared distance sensors 6 detect the distance between them and the square steel in the vertical direction, and transmit electrical signals to the controller 7. When the distance values detected by the plurality of infrared distance sensors 6 are the same (or within the error range), the controller 7 transmits electrical signals to the first motor 9 and the second motor 15, causing the first motor 9 to operate and drive the screw 11 to rotate, so that the upper sliding seat 13 moves horizontally along with the limiting rod 12 and drives the cutting knife 16 to move from one side of the inner space of the bracket 8 to the other side (it can pass through the square steel during the movement). The second motor 15 operates to drive the cutting knife 16 to rotate at a high speed, thereby cutting the pipe end of the square steel passing through the penetration slot 5, so that the pipe end of the square steel remains horizontal during cutting, and the cut section remains vertical, ensuring the accuracy of the cutting position.
