Description

Technical Field

[0001] The utility model relates to a punching machine used for punching holes in C-shaped steel. Background Art

[0002] C-shaped steel is widely used on construction sites. For example, solar panel brackets are all built with C-shaped steel. During the construction process, the C-shaped steels need to be assembled and connected, so holes need to be punched on the sides of the C-shaped steels to facilitate mutual connection and fixation. However, the structure of C-shaped steel is different from that of ordinary pipe fittings. When punching holes, the sides are thinner, so if the entire C-shaped steel is punched, it will cause deformation. Therefore, it is difficult for ordinary punching machines to punch a through hole in the C-shaped steel, that is, to punch holes on both sides at the same time. Moreover, during the process of building the C-shaped steel bracket, the connections on both sides are not necessarily symmetrical, that is, the holes on the two sides do not need to be exactly the same, which causes certain inconveniences in the existing punching machines for C-shaped steel.

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0023] like Figure 1-5As shown, a punching machine for C-shaped steel is mainly used for punching holes on the side of C-shaped steel. Since the structure of C-shaped steel is different from that of ordinary pipe fittings, although the commonly used punching machine can put C-shaped steel, when punching holes on the side, due to its own structure, the downward pressure will cause the C-shaped steel to deform. It includes a punching machine body 1, and a machine head 2 detachably installed on the top of the body 1; the body 1 is an "E"-shaped structure, divided into a punching area 1.1 and a lower clamping area 1.2; with the lower clamping area 1.2, the C-shaped steel can be put on the punching machine from the open surface. Specifically, one side of the C-shaped steel is in the punching area 1.1, and the other side is in the lower clamping area 1.2 (such as Figure 6 As shown); in this way, precise punching can be performed by simply putting the side to be punched into the punching area 1.1; there is a middle support layer 1.5 between the punching area 1.1 and the lower clamping area 1.2, and a punching pad 4 is arranged on the middle support layer 1.5; the bottom of the lower clamping area 1.2 has a lower support layer 1.6.

[0024] A gas source interface 2.1 is provided on one side of the machine head 2 and penetrates through one side of the machine head 2; a gas cylinder 2.2 is provided inside the machine head 2; the machine head 2 is a cylindrical structure, and the diameter of the upper half is larger than that of the lower half.

[0025] One end of the air source interface 2.1 extends to the air cylinder 2.2, and the other end is located on the outside of the machine head 2 for connecting to an external air pump.

[0026] A detachable punching knife 2.3 is provided at the lower end of the cylinder 2.2 for punching holes.

[0027] The top of the main body 1 for mounting the machine head 2 is the upper end 1.4.

[0028] A hole 1.3 is provided on the upper end portion 1.4, and the lower half of the head 2 corresponds to the hole 1.3.

[0029] A spring 5 is arranged in the hole 1.3; specifically, the lower part of the head 2 can be inserted into the spring 5 and fixed on the top of the main body 1; in this way, after the punching knife 2.3 is pushed downward to perform a punching operation through the cylinder 2.2, the external pressure of the air pump is lost, and the punching knife 2.3 can be restored to its original position under the elastic force of the spring 5.

[0030] Limit rods 3 are symmetrically arranged on both sides of the upper end 1.4, and the limit rods 3 are located on both sides of the punching pad 4, so that when the C-shaped steel is placed, it can be accurately put on the punching pad 4 according to the limit rods 3, which is convenient for accurate punching.

[0031] The punch pad 4 is a circular washer, which is hollow in the middle, so that the punch knife 2.3 can fall into the hollow position of the punch pad 4 when punching downwards. That is to say, the punch knife 2.3 is located directly above the punch pad 4.

[0032] When in use, one side of the C-shaped steel to be punched is put on the punching pad 4, and then the external air pump is turned on to drive the cylinder 2.2, and the punching knife 2.3 punches downwards. After the punching is completed, the power input of the air pump is stopped, and the punching knife 2.3 returns to its position upward under the elastic force of the spring 5.

[0033] The beneficial effects of the utility model are:

[0034] The main body of the punching machine is set to an E-shaped structure, with an additional lower card area, which is more in line with the structure of C-shaped steel, making the punching of C-shaped steel more convenient, accurate and will not deform; and the overall structure is simple and easy to carry, so it can be brought directly to the construction site to punch holes in the C-shaped steel according to on-site installation requirements.
