Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a cutting machine for producing thermal insulation pipes with adjustable cutting length. Background Art

[0002] Insulated pipe is the abbreviation of insulated pipe. Insulated pipe is used for the transportation of liquid, gas and other media. It is used for thermal insulation of pipelines in petroleum, chemical industry, aerospace, central heating, central air conditioning, municipal and other fields. In the production process of insulated pipe, it is necessary to cut the longer ones into suitable lengths. After searching, the Chinese patent with publication number CN211164153U discloses an adjustable automatic cutting device for processing insulated pipe fittings. When in use, the insulated pipe fittings are placed on a fixed pipe scaffolding platform and a movable pipe scaffolding platform, and then the second electric cylinder is opened. The piston rod of the second electric cylinder drives the clamping plate connected thereto to move toward the direction of the insulated pipe fittings and contact the insulated pipe fittings, so that the two clamping plates firmly clamp the insulated pipe fittings. After the insulated pipe is fixed on the fixed pipe scaffolding platform and the movable pipe scaffolding platform, the insulated pipe should be sent to the cutting station of the cutting machine. At this time, the second motor is turned on, and the output shaft of the second motor drives the ball screw to rotate between the second motor and the partition, so that the ball nut and the ball nut sleeved on the outer side of the ball screw are rotated. The two connecting rods connected to the mother move horizontally on the ball screw, so that the two connecting rods drive the two movable plates and the movable pipe-laying platform connected to the two movable plates to move toward the direction of the cutting machine under the action of the slider and the slide groove, so that the thermal insulation pipe clamped and placed on the movable pipe-laying platform is sent to the cutting station of the cutting machine. After the thermal insulation pipe moves to a suitable cutting length, the second motor is turned off, the first electric cylinder and the cutting machine are turned on, and the piston rod of the first electric cylinder drives the support rod and the cutting machine connected to the support rod to move toward the direction of the thermal insulation pipe, so that the high-speed rotating saw blade on the cutting machine cuts the thermal insulation pipe into sections, and the cut thermal insulation pipe can be taken out from the discharge hole. However, this cutting method requires the thermal insulation pipe to be clamped, and loading is laborious and time-consuming, and it is easy to cause accidental injury. At the same time, it is not convenient to fix the cutting position, and it is easy to tilt during cutting, and the safety factor is low. For this reason, a cutting machine for thermal insulation pipe production with convenient loading and unloading, high safety factor and high cutting accuracy and adjustable cutting length is designed.

DETAILED DESCRIPTION

[0020] 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.

[0021] Example:

[0022] See also Figure 1-4A cutting machine for producing insulation pipes with adjustable cutting length comprises a frame, a trustee guide slide group is arranged at the bottom of the frame, a clamping mechanism and a blocking mechanism with adjustable position are arranged on both sides of the top of the trustee guide slide group, and a cutting mechanism is also included, and the cutting mechanism is hoisted on the clamping mechanism. Furthermore, the frame comprises a bottom plate 1 and a top plate 2 fixedly mounted on the top of the bottom plate 1 by a plurality of support rods, the trustee guide slide group is arranged on the bottom plate 1, and the clamping mechanism and the blocking mechanism with adjustable position are both arranged on the top plate 2.

[0023] The blocking mechanism includes a blocking seat 3 that is horizontally slidably matched with the top of the frame, and two pipe-blocking bars 5 are symmetrically connected to the blocking seat 3 for rotation. Gears 4 that are rotatably connected to the blocking seat 3 are fixedly installed on the two pipe-blocking bars 5, and the two gears 4 are meshed with each other. A rotating motor 6 that drives one of the gears 4 to rotate is fixedly installed on the blocking seat 3. The rotating motor 6 is started to make the output shaft of the rotating motor 6 rotate clockwise or counterclockwise, so as to drive one of the gears 4 to rotate clockwise or counterclockwise, and through the meshing of the two gears 4, the other gear 4 is driven to rotate counterclockwise or clockwise, so that the two pipe-blocking bars 5 can be rotated inward or outward. When they rotate inward to the bottom, the advancement of the insulation pipe can be blocked, and when the two pipe-blocking bars 5 rotate outward, the insulation pipe can be released from the blocking.

[0024] The machine also includes a horizontal driving assembly for driving the stopper 3 to move, and the horizontal driving assembly includes a one-way screw rod 7 which is horizontally connected to the top of the frame, and the one-way screw rod 7 is threadedly connected to an adjusting slider 8 which is horizontally slidable with the frame. The stopper 3 is fixedly mounted on the bottom of the adjusting slider 8, and an adjusting motor 9 which drives the one-way screw rod 7 to rotate is also fixedly mounted on the frame. When the adjusting motor 9 is started, the output shaft of the adjusting motor 9 rotates clockwise or counterclockwise, thereby driving the adjusting slider 8 to move left or right, thereby driving the stopper 3 to move left or right, and thereby adjusting the horizontal distance between the blocking mechanism and the cutting mechanism, thereby adjusting the cutting length.

[0025] The clamping mechanism includes a lifting frame 10 that slides up and down with the top of the frame, and pressure rollers 12 in the same direction as the trustee guide slide are installed at the four corners of the bottom of the lifting frame 10. The four pressure rollers 12 are symmetrically arranged on both sides of the trustee guide slide. A positioning lifting drive cylinder 11 for driving the lifting frame 10 to rise and fall is fixedly installed on the top of the frame. Starting the positioning lifting drive cylinder 11 is convenient for driving the lifting frame 10 to rise and fall. The four pressure rollers 12 are convenient for clamping the insulation pipe placed on the trustee guide slide from above to prevent it from continuing to move. Since the pressure rollers 12 are arranged in the same direction as the trustee guide slide, the friction force of its continued movement can be increased, thereby improving the stability of the clamping.

[0026] The cutting mechanism is arranged between the four groups of pressure rollers 12, and the cutting mechanism includes a mounting frame 14 hoisted on the lifting frame 10 through a cutting lifting drive cylinder 13, and a cutting blade 15 is connected to the mounting frame 14 through a cutting motor 16 for rotation, and a through hole adapted to the cutting mechanism is provided on the top of the frame. The cutting lifting drive cylinder 13 is started to facilitate the lowering of the mounting frame 14, and the cutting motor 16 is started to facilitate the rotation of the cutting blade 15, and then the cutting blade 15 is lowered with the cooperation of the cutting lifting drive cylinder 13 to cut the insulation pipe.

[0027] The tube guide slide group includes a plurality of guide brackets 17 spaced apart at the bottom of the frame, a transverse roller 18 is rotatably connected to the middle position of the guide bracket 17, and inclined rollers 19 rotatably connected to the guide bracket 17 are arranged on both sides of the transverse roller 18, so that the insulation tube can be guided and moved conveniently through the transverse roller 18 and the two inclined rollers 19.

[0028] When in use, place the insulation pipe from the clamping mechanism side onto the tube guide slide group, then adjust the blocking mechanism to a suitable position according to the length to be cut, and then transport the insulation pipe to the blocking mechanism side. When blocked by the blocking mechanism, the insulation pipe is clamped by the clamping mechanism, and then cut by the cutting mechanism. After cutting, release the clamping mechanism and the blocking mechanism, continue to push the insulation pipe forward, push the cut corrugated pipe down from the right side, and continue the feeding operation, and repeat the above operations.
