Through adopting above-mentioned technical scheme, the stability of scute or mounting plate when removing can be strengthened to the slide bar.

Furthermore, the cross section of the fastening plate is zigzag.

Through adopting above-mentioned technical scheme, the area of mounting plate contact section bar can be reduced to the zigzag to increase the pressure of mounting plate to the section bar, be favorable to mounting plate fixed section bar.

Furthermore, a roller is rotatably arranged on the corner of the angle plate.

By adopting the technical scheme, after the angle plate is contacted with the sectional material, the movement of the sectional material perpendicular to the baffle plate is only limited, and the friction between the angle plate and the sectional material can be reduced by the rolling shaft, so that the angle plate can not obstruct the sectional material from moving to the cutting knife.

Furthermore, a plurality of balls are arranged on the top of the machine body.

Through adopting above-mentioned technical scheme, the ball can show the friction between little section bar and the fuselage top, is favorable to the section bar to remove to the cutting knife.

Further, fastener includes frame, cylinder, pressing tool, the fuselage top is located to the frame, cylinder and pressing tool are located cylinder top and bottom respectively, the output of cylinder runs through the fuselage and connects on the pressing tool.

Through adopting above-mentioned technical scheme, start the cylinder, the pressing tool can move down to can compress tightly the section bar of pressing tool below, make the section bar fixed on vertical.

Furthermore, a guide rod is arranged on the rack in a sliding mode, and one end of the guide rod is connected to the pressing knife.

Through adopting above-mentioned technical scheme, the guide bar can strengthen the stability of pressing the sword, avoids pressing the sword rotatory at the in-process that removes.

Further, a knife groove is formed in the bottom of the pressing knife.

By adopting the technical scheme, the top end of the cutting knife inevitably penetrates above the top of the section bar in the cutting process, so that the knife groove provides a certain storage space for the cutting knife and avoids the rigid contact of the cutting knife and the pressing knife; meanwhile, due to the existence of the cutter grooves, the contact area between the pressing cutter and the section is reduced, the pressure of the pressing cutter to the section is increased, and the section is fixed by the pressing cutter.

To sum up, the beneficial effects of the utility model are that: after the section bar is placed at the top of the machine body, abutted against the baffle and placed between the baffle and the angle plate, the first lead screw transmission mechanism is started to enable the corner of the angle plate to abut against the section bar, so that the position of the section bar can be limited preliminarily, and the section bar cannot move perpendicular to the baffle; the section can also continuously move along the baffle plate at the top of the machine body until the position to be cut on the section is moved to the position above the cutting knife; and the second screw rod transmission mechanism is started again, so that the fastening plate is abutted against the sectional material, the sectional material can be clamped between the fastening plate and the baffle plate under the clamping of the fastening plate, and the sectional material is limited at the top of the machine body before being fixed by the fastening device, so that the position deviation cannot occur, the cutting position of the sectional material is accurate, and the section material cannot be scrapped due to the generation.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model provides a cutting machine presss from both sides tight material device, including fuselage 1, cutting knife 2, fastener 3, cutting knife 2 is located in fuselage 1 to the last shearing of fuselage 1 has the strip hole 11 that supplies cutting knife 2 to remove. The fastening device 3 comprises a frame 31, a cylinder 32 and a pressing knife 33, wherein the frame 31 is assembled on the top of the machine body 1 above the strip hole 11 in a threaded mode, the cylinder 32 and the pressing knife 33 are respectively arranged on the top and the bottom of the cylinder 32, and the output end of the cylinder 32 penetrates through the machine body 1 and is connected to the pressing knife 33.

Referring to fig. 6, a guide rod 311 is slidably disposed on the frame 31, and one end of the guide rod 311 is connected to the pressing blade 33, which can enhance the stability of the pressing blade 33 and prevent the pressing blade 33 from rotating during movement. By activating the cylinder 32, the pressing blade 33 can move downwards, so that the profile below the pressing blade 33 is pressed, and the profile is fixed in the vertical direction. And a knife groove 331 is integrally formed at the bottom of the pressing blade 33. In the cutting process of the cutting knife 2, the top end of the cutting knife 2 inevitably penetrates above the top of the section bar, so that the knife groove 331 provides a certain storage space for the cutting knife 2 and prevents the cutting knife 2 from rigidly contacting the pressing knife 33; meanwhile, due to the existence of the knife grooves 331, the contact area between the pressing knife 33 and the profile is reduced, the pressure of the pressing knife 33 to the profile is increased, and the fixing of the profile by the pressing knife 33 is facilitated. A plurality of balls 13 are arranged on the top of the machine body 1 in a rolling way. The balls 13 can show the friction between the small section bar and the top of the machine body 1, which is beneficial to the section bar moving towards the cutting knife 2.

With reference to fig. 3 and 4, the body 1 is further provided with a baffle 12, a first screw rod transmission mechanism 4 and a second screw rod transmission mechanism 5, and the baffle 12 is assembled on the top of the side surface of the body 1 in a threaded manner. The first screw rod transmission mechanism 4 comprises a first screw rod 41 and an angle plate 42 which is assembled on the first screw rod 41 in a threaded manner, two ends of the first screw rod 41 are rotatably connected to the baffle 12, and the cross section of the angle plate 42 is L-shaped; the second screw rod transmission mechanism 5 comprises a second screw rod 51 and a fastening plate 52 which is assembled on the second screw rod 51 in a threaded mode, and two ends of the second screw rod 51 are rotatably connected to the baffle 12.

The first screw transmission mechanism 4 and the second screw transmission mechanism 5 both comprise a sliding rod 6, two ends of the sliding rod 6 are in interference fit with the baffle 12, and the angle plate 42 or the fastening plate 52 is slidably connected on the sliding rod 6. The sliding rod 6 can strengthen the stability of the angle plate 42 or the fastening plate 52 when moving. The fastening plate 52 is serrated in cross-section. The saw-tooth shape can reduce the area of the fastening plate 52 contacting the section bar, thereby increasing the pressure of the fastening plate 52 to the section bar and being beneficial to the fastening plate 52 to fix the section bar; the corner plate 42 is provided with a roller 421 (shown in fig. 5) at the corner thereof. The roller 421 reduces the friction between the angle plate 42 and the profile after the angle plate 42 contacts the profile, only to limit the profile from moving perpendicular to the baffle 12, so that the angle plate 42 does not hinder the profile from moving towards the cutting knife 2.

The utility model discloses an implement the principle and do: after the profile is placed on the top of the fuselage 1, against the apron 12 and between the apron 12 and the angle plate 42, the first screw transmission 4 is first activated, causing the roller 421 of the angle plate 42 to abut against the profile. Because the contact area between the corner of the angle plate 42 and the profile is small, the position of the profile can be limited only preliminarily, so that the profile cannot move perpendicular to the baffle 12, and the profile can move along the baffle 12 continuously at the top of the machine body 1 until the position to be cut on the profile is moved above the cutting knife 2;
