Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to provide a channel steel punching and cutting device, which is used for solving the technical problems in the prior art and realizing the quick and smooth cutting of channel steel.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

As shown in fig. 1-2, the embodiment provides a channel steel punching and cutting device, which includes a cutter 1, a riser assembly and a base 7.

The tool 1 is mounted on a hydraulic telescopic head of the machine tool, and the hydraulic telescopic head is used for driving the tool 1 to move up and down to complete the cutting-off action of the channel steel. Cutter 1 includes the isosceles obtuse triangle-shaped portion of the rectangle portion of upside and downside, and the apex angle of isosceles obtuse triangle-shaped portion is down to increase initial pressure, be convenient for cut off. The vertical plate assembly comprises a first vertical plate 3 and a second vertical plate 4, and the first vertical plate 3 is opposite to the second vertical plate 4 and is fixedly connected into a whole through a fastener. The vertical edges 5 are arranged at the transverse edge positions on the right opposite surfaces of the first vertical plate 3 and the second vertical plate 4, a knife groove for the knife 1 to pass through is formed between the first vertical plate 3 and the second vertical plate 4 after the vertical edges 5 are abutted against each other, the width of the knife groove is preferably twice of the thickness of the knife 1, and the knife hitting phenomenon is avoided. Be equipped with the logical groove 6 that the position is just right on first riser 3 and the second riser 4, lead to groove 6 and wait to cut the channel-section steel shape the same, wait to cut the channel-section steel and pass the riser subassembly by leading to groove 6. The riser assembly is mounted on the base 7 and supported by the base 7.

This channel-section steel punching press cutting device is when using, passes the channel-section steel through the logical groove 6 that corresponds on first riser 3 and the second riser 4, can control the flexible head of hydraulic pressure and drive cutter 1 and descend after advancing to target in place with the channel-section steel, accomplishes and cuts off the action, then continues subsequent feeding and cut off work.

In order to guide and cushion the up and down movement of the tool 1, the present embodiment further comprises a vertical rod 8, a sleeve 9 and a spring 10. The sleeve 9 is vertically fixed on the base 7, the upright rod 8 and the cutter 1 are fixed on the cutter support 2, the cutter support 2 is fixed on the hydraulic telescopic head, and the lower end of the upright rod 8 is inserted into the sleeve 9. When the upright 8 slides up and down in the sleeve 9, the sleeve 9 guides the up-and-down movement of the upright 8, thereby guiding the tool holder 2 and the tool 1 fixed relative to the upright 8. The spring 10 is sleeved outside the upright rod 8, and the cutter support 2 can be abutted against the upper end of the spring 10 when moving downwards, so that a buffering effect is achieved.

Since the mold for the guard rail of the expressway is formed by combining various channel steels, the various channel steels need to be cut. In order to reduce the cost, the number of the through slots 6 is multiple in the embodiment, and each through slot 6 corresponds to one channel steel shape and is used for cutting various channel steels.

When the different through grooves 6 are in different transverse positions, the cutter 1 is easily damaged due to uneven stress when being cut. Therefore, the embodiment further comprises a positioning assembly, the positioning assembly is used for fixing the vertical plate assembly, the base 7 is provided with a transverse sliding groove, and the lower portion of the vertical plate assembly is embedded into the transverse sliding groove and can transversely slide along the transverse sliding groove. Through sliding the riser subassembly in the spout, then fix through locating component, the horizontal position of adjustment channel-section steel makes cutter 1 atress even.

In this embodiment, the positioning assemblies are two groups, and include a positioning cylinder 11 and a positioning block 12. The positioning cylinder 11 is used for being fixed on the workbench, the positioning blocks 12 are fixed at the extending ends of the piston rods of the positioning cylinder 11, and the positioning blocks 12 of the two groups of positioning assemblies are respectively used for abutting against the two transverse ends of the vertical plate assembly to realize the positioning of the vertical plate assembly.

In order to prevent the riser subassembly from falling out of the spout, the spout is the T-shaped groove of inversion in this embodiment, and the macrostoma end of spout is down, and the bottom of riser is equipped with the evagination structure, and the evagination structure is spacing to offset with the T-shaped groove.

The concrete form of evagination structure has the multiple, as long as can play limiting displacement can. For example, in the present embodiment, the external convex structure is a horizontal plate 13, and the horizontal plate 13 is installed at the bottom of the vertical plate through a vertical fastening screw 14; the convex structure can also be a plurality of longitudinal fastening screws which are distributed at equal intervals along the transverse direction.

The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
