Description

Technical Field

[0001] The utility model relates to the technical field of profile cutting, in particular to a device for automatically cutting profiles in a quantitative manner. Background Art

[0002] During machining, cutting of sheet metal or profiles is often necessary. Therefore, cutting machines play an indispensable role in the production of various machined products. With the increasing demand for automated machining, existing cutting machines are gradually becoming more automated.

[0003] At present, most of the existing automatic cutting machines include a loading device for conveying profiles and a cutting device for cutting profiles. Their working principle is: the profile is placed on the conveying part of the loading device and fixed, and then the loading device drives the profile to move to the cutting part of the cutting device, so that the profile can be automatically cut.

[0004] In the above solution, the existing automatic cutting machine spends a long time doing useless work, resulting in low cutting efficiency of the profiles, and the debris generated by the cutting will fly everywhere, which is likely to cause harm to the workers. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a device for automatically cutting profiles in a quantitative manner. By providing a chip removal component and a reciprocating movement mechanism, the cutting machine can be quickly driven to reset and the debris generated during cutting can be removed, thereby solving the problems of low cutting efficiency and debris flying everywhere in the existing technology, thereby ensuring that workers will not be injured and improving practicality.

[0006] The solution of the utility model to solve the technical problem is:

[0007] A device for automatically cutting profiles in a quantitative manner includes a body, two first slide rails are symmetrically fixed to the upper end of the body, a plurality of first sliders are slidably connected to the first slide rails, the upper ends of the plurality of first sliders are fixed to the same support plate, a group of downward pressing devices are respectively installed on the upper ends of the body and the support plate, a chip removal assembly is provided on the side wall of one group of downward pressing devices, a screw conveying device is installed on the upper end of the body, the movable end of the screw conveying device is fixed to the lower end of the support plate, a reciprocating mechanism is provided in the body, and a cutting machine is provided on the reciprocating mechanism.

[0008] When the profile needs to be cut to a fixed length, the profile is placed on the upper end of the support plate and the profile is located at the extrusion position of the down-pressing device, one of the groups of down-pressing devices is started to extrude and fix the profile, and then the screw conveying device is started to drive the support plate to move. The movement of the support plate drives one of the groups of down-pressing devices to move, thereby driving the profile to move. When the profile moves to the extrusion position of the other group of down-pressing devices and the profile passes through the protruding end of the other group of down-pressing devices to the required length, the screw conveying device is controlled to stop working, and the other group of down-pressing devices is started to extrude and fix the profile, thereby ensuring that the profile will not deviate during cutting, and then the reciprocating mechanism is started to drive the cutting machine to move outward, so that the profile can be cut to a fixed length, and the chip removal component is started at the same time, so that the debris generated by the cutting machine during cutting can be extracted. After the fixed-length cutting of the profile is completed, when the cutting machine needs to be driven to move inward for reset, the reset moving mechanism can quickly drive the cutting machine to move inward for reset, thereby reducing the reset time of the cutting machine and improving the cutting efficiency.

[0009] By providing a chip removal component and a reciprocating movement mechanism, the cutting machine can be quickly driven to reset and the debris generated during cutting can be removed, solving the problems of low cutting efficiency and debris flying everywhere in the existing technology, thereby ensuring that workers will not be injured and improving practicality.

[0010] The utility model is further configured as follows: the chip removal assembly includes a chip guard plate fixed on the side wall of one group of the pressing devices, and an exhaust pipe is installed on the side wall of the chip guard plate.

[0011] Through the above technical solution, when it is necessary to remove the debris generated by the cutting machine, the exhaust pipe is started to remove the debris generated by the cutting machine. At the same time, by providing a chip guard plate, the debris can be prevented from splashing everywhere, and the exhaust pipe can remove the debris more effectively.

[0012] The utility model is further configured as follows: the reciprocating mechanism includes a guide assembly and a reciprocating assembly, the guide assembly includes two second slide rails symmetrically fixed on the inner wall of the machine body, and a plurality of second sliders cooperating with the second slide rails are fixed on the side wall of the cutting machine.

[0013] The above technical solution ensures that the cutting machine will not deflect or vibrate when it moves back and forth, thereby ensuring that the cutting quality of the profile is not affected.

[0014] The utility model is further configured as follows: the reciprocating moving component includes a first connecting rod rotatably connected to the lower end of the cutting machine, a sliding groove is formed on the side wall of the first connecting rod, a sliding block is slidably connected in the sliding groove, the end of the first connecting rod is rotatably connected to the second connecting rod, the second connecting rod is rotatably connected to the inner wall of the machine body, a motor is fixed on the inner wall of the machine body, a turntable is fixed on the output end of the motor, a round rod is fixed on the side wall of the turntable, the round rod is eccentrically arranged with the turntable, and the round rod is rotatably connected to the side wall of the sliding block.

[0015] Through the above technical solution, when it is necessary to drive the cutting machine to move back and forth, the motor is started to drive the turntable to rotate, the rotation of the turntable drives the round rod to rotate, the rotation of the round rod drives the sliding block to move, and the movement of the sliding block drives the first connecting rod and the second connecting rod to rotate, thereby driving the cutting machine to move back and forth. At the same time, under the action of the second connecting rod, the outward movement speed of the cutting machine is slow, so that the profile can be cut smoothly and stably, and the inward movement speed of the cutting machine is fast, so that the cutting machine can be quickly driven to reset.

[0016] The utility model is further configured as follows: a cylinder is fixed on the upper end of the support plate, and a side pressure plate is fixed on the output end of the cylinder.

[0017] With the above technical solution, after the profile is squeezed and fixed by the pressing device, the cylinder is started to drive the side pressure plate to press against the side wall of the profile, thereby further limiting and fixing the profile.

[0018] The beneficial effects of the utility model are:

[0019] Compared with the existing technology, the chip removal component and the reciprocating movement mechanism are provided, so that the cutting machine can be quickly driven to reset and the debris generated during cutting can be removed, solving the problems of low cutting efficiency and debris flying everywhere in the existing technology, thereby ensuring that the staff will not be injured and improving practicality.
