Description

Technical Field

[0001] The utility model relates to the technical field of cold-drawn tube fixed-length cutting, in particular to a fixed-length cutting device for cold-drawn tube processing. Background Art

[0002] Cold drawn steel pipe is a kind of steel pipe, which is classified according to different production processes. Different from hot rolled pipe, it is made by multiple cold drawing processes during the expansion of rough pipe or raw material pipe, usually on a 0.5-100T single-chain or double-chain cold drawing machine;

[0003] For the subsequent assembly and use of the cold-drawn tube, a single long cold-drawn tube needs to be cut into multiple short cold-drawn tubes of the same length. After the operator adjusts the cutting tool on the operating table, he pulls the cold-drawn tube with one hand and presses the cold-drawn tube on the tool with the other hand, and cooperates with the cutting machine in the descending process to achieve fixed-length cutting of the cold-drawn tube. Since the operator's work position corresponds to the cutting machine, there are safety hazards in the cold-drawn tube cutting process. At the same time, the cold-drawn tube is pulled and abutted against the tool, which results in a large workload and low fixed-length cutting efficiency;

[0004] To this end, we propose a fixed-length cutting device for cold-drawn tube processing. Utility Model Content

[0005] The utility model aims to provide a fixed-length cutting device for cold-drawn tube processing to solve the problems of heavy workload and low fixed-length cutting efficiency caused by artificial pulling of the cold-drawn tube and contact with tooling.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A sliding sleeve is slidably connected to one side of the cutting table, and a cutting machine is installed on the sliding sleeve. Two springs are evenly and symmetrically installed on both sides of the sliding sleeve, and a storage box is installed on one side of the cutting table.

[0010] Furthermore, a baffle is fixedly connected to the top of the cutting table, a baffle is slidably connected to the baffle, a spring is sleeved on the baffle opposite to the baffle, slots are evenly arranged on the baffle, and a protrusion on one side of the rotating arm is engaged with the slot.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 , the utility model provides a technical solution:

[0024] like Figure 1 As shown, the main body of the cold-drawn tube fixed-length cutting equipment is a cutting table 1, and a placing table 15 is installed on one side of the cutting table 1 for moving and transporting the cold-drawn tube. The fixed-length mechanism 3 sliding in the slide groove 2 on the cutting table 1 is used to adjust the length of the cut cold-drawn tube, and the cut cold-drawn tube automatically falls into a storage box 14 installed on one side of the cutting table 1;

[0025] Regarding the transmission and movement of the cold-drawn tube, a movable block 19 is slidably connected in the slot on the placement table 15. The position of the entire movable block 19 in the slot is adjusted by rotating the threaded knob 18 on the top of the placement table 15, so as to facilitate the clamping of cold-drawn tubes of different diameters. Since one end of the cold-drawn tube needs to abut against the rotating arm 302 in the fixed-length cutting equipment, and then cutting is performed, the transmission disk 17 on the output end of the entire motor 16 continuously drives the cold-drawn tube to move to one side. For this reason, the friction of the transmission disk 17 on the surface of the cold-drawn tube is reduced, and the sliding connection in the movable block 19 There is a square gasket 20, and a spring 3 22 is installed at the bottom of the square gasket 20. The end of the threaded knob 2 18 passes through the movable block 19 and is movably connected to the square gasket 20, so that the threaded knob 2 18 can not only drive the movable block 19 to move on the placement table 15, but also the clamping plate 21 on one side of the movable block 19 is in an active state, not fixedly clamped. When one end of the cold-drawn tube contacts the rotating arm 302, the transmission plate 17 and the clamping plate 21 are in an idling state. Compared with the clamping of the disks on both sides of the cold-drawn tube, the wear on the outer wall of the cold-drawn tube is increased during the idling process.

[0026] The length fixing mechanism 3 on the entire cutting table 1 is as follows Figure 3 and Figure 4 As shown, both sides of the slide box 301 are clamped in the slide slot 2. In order to limit the position of the entire slide box 301 in the slide slot 2, a threaded knob 304 is movably connected at the rear of the slide box 301, wherein the end of the threaded knob 304 penetrates the slide box 301 and is movably connected to one side of the cut block 305 sliding in the slide box 301, and the longitudinal section of the cut block 305 is an isosceles trapezoid. At the same time, friction blocks 306 are symmetrically slidably connected at the upper and lower sides of the slide box 301. The friction block 306 penetrates the slide box 301 and abuts on the section of the cut block 305. When the threaded knob 304 is manually rotated inward to drive the cut block 305 to move to one side, the cut block 305 moves and pushes the friction block 306 outward, causing the friction block 306 to continuously press against the upper and lower inner walls of the slide slot 2, thereby achieving the limit fixation of the entire slide box 301;

[0027] A rotating arm 302 is rotatably connected to one side of the slide box 301, and a limiting column 303 is fixedly connected to one side of the slide box 301. The installation of the limiting column 303 limits the rotation angle of the entire rotating arm 302 to one side, and the protrusion on the rotating arm 302 abuts against the card slot 5 on the top stopper 4 of the cutting table 1. Figure 1 As shown, whenever one end of the cold-drawn tube contacts one side of the rotating arm 302, the rotating rotating arm 302 will push the stopper 4 to move to the right;

[0028] The overall structure of the block 4 is as follows Figure 2As shown, the rightward movement of the stopper 4 depends on the rotation of the rotating arm 302, and the leftward movement is pushed by the spring 7 on the baffle 6. The baffle 6 is fixed on the cutting table 1. An L-shaped pad is installed on one side of the stopper 4. The L-shaped pad moves up and down through an elastic mechanism. Under the push of the rotating arm 302, the L-shaped pad on one side of the stopper 4 enters the bottom of the pressing block 13, and the pressing block 13 pushes the movement of the sliding sleeve 8 on the cutting table 1.

[0029] Under normal conditions, a turntable 11 is movably connected to the top of the cutting table 1, and a movable rotating rod 12 on the turntable 11 is movably connected to a pressing block 13, so that the turntable 11 rotates to drive the pressing block 13 to move up and down on the surface of the cutting table 1, but the moving distance of the pressing block 13 is limited and it cannot contact the sliding sleeve 8. A belt is provided on the belt pulley on one side of the turntable 11 and the belt pulley on the output end of the motor 16, that is, the transmission disk 17 rotates continuously, and at the same time, the rotation of the entire turntable 11 drives the pressing block 13 to move up and down continuously;

[0030] Then Figure 2 As shown, when the L-shaped pad on one side of the stopper 4 is pressed to push the sliding sleeve 8 downward, the blade at the end of the cutting machine 10 installed on the sliding sleeve 8 cuts the cold-drawn tube, and the cold-drawn tube after the segment cutting cannot exert a thrust on the side of the rotating arm 302, and the rebound of the spring 1 7 pushes the entire fixed length mechanism 3 to reset until one end of the cold-drawn tube contacts the rotating arm 302 again, and the spring 2 9 at the bottom of the sliding sleeve 8 also pushes the entire sliding sleeve 8 to reset;

[0031] Taking into account that the L-shaped pad on one side of the stopper 4 does not enter every time when the pressure block 13 rises, and the abutment of the L-shaped pad during the descending process of the pressure block 13 will be solved by the idling of the clamping plate 21 and the transmission plate 17, in addition, in order to facilitate the fixed-length cutting of cold-drawn tubes of different diameters, since the cutting depth of the blade of the cutting machine 10 is limited, a cold-drawn tube rotating clamp can be installed on the cutting table 1 to drive the entire cold-drawn tube to rotate at a fixed point, thereby ensuring that the descending distance of the cutting blade is fixed, and the fixed-length cutting of the entire large-diameter cold-drawn tube can also be performed.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
