Problems solved by technology

[0002] C-shaped steel is widely used in many fields such as construction, industrial and agricultural production, etc. It is mainly used as the skeleton of construction facilities or industrial equipment. Traditional C-shaped steel is generally a long strip structure with the same cross-sectional shape. This kind of C-shaped steel can be used in existing The mature roll forming equipment in the technology is used for rapid production. However, in order to adapt to the assembly of some special occasions, the inventor of the present invention has designed a C-shaped steel with sinker structure, that is, multiple The sinker, the sinker is formed by bending the bottom corner of the C-shaped steel inwards, but there is no corresponding reliable equipment in the prior art to realize the continuous production of this C-shaped steel, and due to the existence of the sinker, this C-shaped During the packaging process, the section steel cannot be buckled in pairs like the traditional C-section steel, but a new fastening method is needed to save the floor space during transportation and storage.

Embodiment 1

[0046] A profile processing system, including a roll forming machine for rolling steel strips into C-shaped steel 1. The front end of the roll forming machine is equipped with a punching die for punching strip-shaped gaps on the steel strip. The strip-shaped gaps 3 Twos form a group and the length direction of the strip-shaped gap 3 is parallel to the width direction of the steel strip. The rear end of the roll forming machine is equipped with a local forming device for bending the bottom angle 2 between the two shaped gaps 3 inwards into a sinking groove 4, such as figure 2 , 3, 4, the local molding device includes a female mold and a male mold, and the female mold includes a first working surface 11 and a second working surface 12, and the first working surface 11 and the second working surface 12 have a mutual fit side, the first working surface 11 and the second working surface 12 form a relative pivotal fit with the mutually fitted side as the axis, and the first workin...

Embodiment 2

[0062] A method for system processing profiles described in embodiment 1, comprising the steps of:

[0063] Step 1: using a punching die to punch out two parallel slits 3 on the steel strip, the length direction of the two slits 3 is parallel to the width direction of the steel strip;

[0064] Step 2: using a roll forming machine to roll the steel strip into a C-shaped steel 1, and the hemming at the bottom corner 2 of the C-shaped steel 1 is just located on the vertical middle line of the gap 3;

[0065] Step 3: Use a local forming device to fold the corner between the two gaps 3 inwards to form the sinker 4; The bottom surface and the side surface of the bottom corner 2 are turned inward, and the turning angles of the bottom surface and the side surface are both 90°;

[0066] Step 4: cutting the formed C-shaped steel 1 from the front end material;

[0067] Step 5: Arrange four C-shaped steels 1 along the circumferential direction, and the four C-shaped steels 1 are paralle...

Abstract

The invention belongs to the technical field of profile support production and machining, and particularly relates to a profile machining method. The method comprises the steps that firstly, a gap used for separating a sinking groove area is punched in a steel belt through a punching die, then the steel belt is rolled into C-type steel through rolling forming equipment, then the sinking groove area is independently punched and formed through a local forming device, and the forming efficiency is improved. According to the method, vortex-shaped buckling among the four pieces of C-type steel is achieved through a packaging device, the occupied space during stacking of C-type steel finished products is reduced to the maximum extent, and therefore the storage and transportation cost of the C-type steel is indirectly reduced.
