Technical Field

The application relates to the field of angle steel processing equipment, in particular to a die for cutting angle steel.

Background

Angle steel is commonly called angle iron and is long-strip steel with two sides perpendicular to each other to form a right angle. The angle steel is divided into equal angle steel and unequal angle steel. The angle steel can form various different stressed components according to different requirements of structures, can also be used as a connecting piece between components, and is widely applied to building structures and engineering structures in various places, such as house beams, bridges, power transmission towers, hoisting and transporting machinery, ships, industrial furnaces, reaction towers, container frames, cable trench supports, power distribution pipes, bus support installation, warehouse goods shelves and the like.

The angle steel needs to be cut into the appointed length according to the requirement in the use process. In some small uses, the angle steel can be manually cut into a proper length by a cutting device such as a cutting machine. However, for some large-scale production lines or scenes with high requirements on the specification of angle steel, a specified length needs to be cut, and manual cutting is not suitable for the scenes. Due to the limitation of the structure of the angle steel, the angle steel is easy to deform when being directly cut, and the cutting quality is difficult to meet the requirements.

And a die hole 23 for placing angle steel is horizontally arranged on the left die 21 and the right die 22 in a penetrating manner, and the angle steel is penetrated in the die hole 23 when cutting is carried out.

Referring to fig. 2 and 3, the cross section of the die hole 23 is square, and two diagonal lines of the cross section of the die hole 23 are respectively arranged vertically and horizontally, that is, the lower half of the die hole 23 is opened at an angle of 90 °. When the angle steel is placed in the die hole 23, the angle steel is opened upwards and two sides cling to two side edges of the die hole 23. Still be fixed with two backing plates 24 through the bolt between left mould 21 and right mould 22, two backing plates 24 are located the both sides of nib 23, and left mould 21, right mould 22 and two backing plates 24 enclose out the cutting way 3 that supplies cutter 5 to remove, and cutter 5 vertically slides in cutting way 3, and the cutting range of cutter 5 covers whole cutting way 3. After the angle steel passes through the die hole 23 and is placed on the die 2, the punching machine drives the cutter 5 to vertically move so as to cut the angle steel.

Referring to fig. 3, the waste discharge cavity 4 has been still seted up between left side mould 21 and the right side mould 22, and waste discharge cavity 4 is located the below of nib 23 and communicates with cutting path 3, and cutter 5 can produce waste materials such as iron fillings or leftover bits when cutting the angle steel, and these waste material cards are in cutting path 3, can block up cutting path 3 after accumulating gradually, influence cutter 5's removal, and then influence the cutting quality. So through offering waste discharge chamber 4 below cutting way 3, the waste material that produces in the cutting process drops in waste discharge chamber 4, treats cutting and accomplishes the back and in unified clearance, avoids blockking up cutting way 3.

Referring to fig. 2 and 3, the cutter 5 includes a handle 51 and a blade 52, the handle 51 and the blade 52 are fixedly connected through a bolt, the handle 51 is used for being connected with a punching machine, and the handle 51 drives the blade 52 to vertically slide in the cutting path 3 to cut angle steel. The cutting end of the blade 52 is configured in a V-shape, and the opening angle of two sides of the V-shaped part is larger than 90 degrees. Through the arrangement, when the cutter body 52 moves downwards to cut the angle steel, the cutting end of the cutter body 52 is in inclined contact with two edges of the angle steel, so that the cutter 5 can conveniently cut the angle steel.

Referring to fig. 4, the supporting seat 6 includes a fixed seat 61 and a movable seat 62, and the fixed seat 61 abuts against two sides of the mold 2 where the mold hole 23 opens. The holding groove 63 that is the V type is all seted up in the upper end of fixing base 61 and sliding seat 62, and the angle that opens of holding groove 63 both sides is 90, and the both sides wall of holding groove 63 flushes with the both sides of nib 23 the latter half. Two guide bars 64 are fixedly connected to one end of the fixed seat 61 far away from the die 2 through threads, the guide bars 64 are horizontally arranged, guide holes 621 matched with the guide bars 64 are formed in the movable seat 62, the guide bars 64 penetrate through the guide holes 621, and sliding connection between the movable seat 62 and the guide bars 64 is achieved through matching of the guide bars 64 and the guide holes 621. One end of the guide rod 64 is integrally formed with a screw, and the other end is provided with a threaded hole matched with the screw. The screw end of the guide rod 64 is connected with the fixed seat 61, the threaded hole end is in threaded connection with a limiting bolt 65, and the movable seat 62 can be prevented from being separated from the guide rod 64 through the limiting bolt 65. A plurality of guide rods 64 may be threaded end to increase the length of the guide rods 64.

In order to make the fixing base 61 support tightly on the die holder 1 and avoid the fixing base 61 to produce lateral deviation, referring to fig. 2, the positioning groove 25 is provided on the side walls of the left die 21 and the right die 22, one end of the fixing base 61 is clamped in the positioning groove 25, and the part of the fixing base 61 supports against the side wall of the positioning groove 25, so that the fixing base 61 is clamped in the positioning groove 25 and does not produce lateral deviation.

The implementation principle of the die 2 for cutting the angle steel is as follows: when cutting the angle steel, place supporting seat 6 in the both sides of mould 2 earlier to make the one end of fixing base 61 support tightly in the constant head tank 25, then wear to establish the angle steel opening upwards and place in nib 23, the part that the angle steel is located the nib 23 outside is placed on supporting seat 6. The punching machine is started to drive the cutter 5 to vertically move to punch the angle steel, waste materials generated in the cutting process of the angle steel fall into the waste discharge cavity 4 below through the cutting channel 3, and the bolt is unscrewed after the cutting is finished to uniformly clean the waste materials in the waste discharge cavity 4. When the length of the angle steel to be cut is long, the movable seat 62 is adjusted to slide on the guide rods 64 in the direction away from the fixed seat 61 so as to increase the supporting range, meanwhile, the number of the guide rods 64 can be increased, a plurality of guide rods 64 are connected end to end, and the adjustable range of the movable seat 62 is further increased.
