The tool can perform corner-back cutting of angle steel on the corner cutting machine in one time, thereby saving the pneumatic back cutting procedures, shortening the machining time, saving the machining cost and improving the machining efficiency.

Description

Electric power tower angle steel tower material cornering machine with corner cut, cut back of the body cutter

Technical field

The utility model relates to the cutting knife cutter on a kind of cornering machine, relate in particular to a kind of electric power tower angle steel tower material cornering machine with corner cut, cut back of the body cutter.

Background technology

The segment angle head tower material of electric power tower is when continuous, install for avoiding bumping against influence between the angle steel, usually need carry out corner cut or cut back of the body processing the position that influences the angle steel installation, at present the cutting knife cutter of the cornering machine used of electric power tower angle steel tower material can only corner cut, and both needed corner cut need cut the angle steel of the back of the body, because the cutting knife of cornering machine and the restriction of angle steel shape, can't cut the back of the body at following cutter after the corner cut, can only cut the back of the body with gas cutting again after the corner cut, so just need multiple working procedure to finish processing, waste time and energy, working (machining) efficiency is low, utilization rate of equipment and installations is not high, the production cycle is long.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of electric power tower angle steel tower material cornering machine with corner cut, cut back of the body cutter, this cutter can be on cornering machine once property angle steel carried out corner cut cut the back of the body, save the pneumatic back of the body operation of cutting, shortened process time, save processing cost, improved working (machining) efficiency.

For solving the problems of the technologies described above, the technical solution of the utility model is: electric power tower angle steel tower material cornering machine corner cut, cut back of the body cutter, the upper cutter and the lower cutter that comprise mutual coupling, described upper cutter comprises orthogonal two first upper knife edges, described lower cutter comprises orthogonal two first time blades, two ends, inboard inwardly protruding of described lower cutter forms two second time blades, described every second time blade intersects the obtuse angle with corresponding first time blade respectively, and two ends, the outside of described upper cutter are provided with two second upper knife edges with described second time blade coupling.

As a kind of preferred version, described second upper knife edge and first upper knife edge intersect 135 °; Described second time blade and described first time blade intersect 135 °.

After having adopted technique scheme, effect of the present utility model is: because two ends, inboard inwardly protruding of described lower cutter forms two second time blades, described every second time blade intersects the obtuse angle with corresponding first time blade respectively, two ends, the outside of described upper cutter are provided with two second upper knife edges with described second time blade coupling, therefore add man-hour, need cutting two cuttves altogether, the first cutter corner cut, second cutter is cut the back of the body, the steel plate monomer that needs corner cut of angle steel is called corner cut steel plate monomer, and the steel plate monomer that the needs of angle steel are cut the back of the body is called cuts the back steel sheet monomer.Corner cut at first, wherein one first upper knife edge and first time corresponding blade cooperate together along cutting back steel sheet monomer medial surface cutting corner cut steel plate monomer, just along the intersecting lens cutting corner cut steel plate monomer of cutting back steel sheet monomer and corner cut steel plate monomer medial surface, simultaneously, corresponding second upper knife edge and second time blade cooperate an angle that cuts away corner cut steel plate monomer together, and the waste material that the corner cut operation is downcut is a steel plate that the obtuse angle is trapezoidal; Be to cut the back of the body then, because the first cutter corner cut operation is cut away the crossing end with cutting the back steel sheet monomer of corner cut steel plate monomer, therefore just do not hinder down cutter, utilize another second upper knife edge and second time corresponding blade to cooperate the back of the body that to cut the back steel sheet monomer to cut away together, the waste material of cutting the cutting-out of back of the body operation is a leg-of-mutton steel plate, like this this cutter can be on cornering machine once property angle steel carried out corner cut cut the back of the body, save the pneumatic back of the body operation of cutting, shortened process time, save processing cost, improved working (machining) efficiency.

The specific embodiment

A kind of electric power tower angle steel tower material cornering machine corner cut, cut back of the body cutter, as depicted in figs. 1 and 2, it comprises the upper cutter 2 and the lower cutter 1 of mutual coupling, described upper cutter 2 comprises orthogonal two first upper knife edges 21, described lower cutter 1 comprises orthogonal two first time blades 11, two ends, inboard inwardly protruding of described lower cutter 1 forms two second time blades 12, described every second time blade 12 intersects the obtuse angle with corresponding first time blade 11 respectively, and two ends, the outside of described upper cutter 2 are provided with two second upper knife edges 22 with described second time blade, 12 couplings.Preferably, described second upper knife edge 22 and first upper knife edge 21 intersect 135 °; Described second time blade 12 intersects 135 ° with described first time blade 11

Operation principle of the present utility model is: add man-hour, need cutting two cuttves altogether, the first cutter corner cut, second cutter is cut the back of the body, as shown in Figure 3, the steel plate monomer that needs corner cut of angle steel 3 is called corner cut steel plate monomer 31, the steel plate monomer that the needs of angle steel 3 are cut the back of the body is called cuts back steel sheet monomer 32.Corner cut at first, as shown in Figure 4, wherein one first upper knife edge 21 and first time corresponding blade 11 cooperate together along cutting back steel sheet monomer 32 medial surfaces cutting corner cut steel plate monomer 31, just along cutting the intersecting lens cutting corner cut steel plate monomer 31 of back steel sheet monomer 32 with corner cut steel plate monomer 31 medial surfaces, simultaneously, corresponding second upper knife edge 22 and second time blade 12 cooperate an angle that cuts away corner cut steel plate monomer 31 together, and the waste material that the corner cut operation is downcut is a steel plate that the obtuse angle is trapezoidal; Be to cut the back of the body then, as shown in Figure 5, since the first cutter corner cut operation corner cut steel plate monomer 31 with cut the end that back steel sheet monomer 32 intersects and cut away, therefore just do not hinder down cutter, utilize another second upper knife edge 22 and second time corresponding blade 12 to cooperate the back of the body that to cut back steel sheet monomer 32 to cut away together, the waste material of cutting the cutting-out of back of the body operation is a leg-of-mutton steel plate, like this this cutter can be on cornering machine once property angle steel 3 carried out corner cut cut the back of the body, save the pneumatic back of the body operation of cutting, shortened process time, save processing cost, improved working (machining) efficiency.
