Description

Technical Field

[0001] The utility model relates to metal frame processing equipment, in particular to a welded metal frame trimming machine. Background Art

[0002] The metal frame is made of metal strips, metal wires or metal plates that are bent, assembled and welded according to needs. To ensure that the size requirements are met and to facilitate welding, some metal strips will be welded with a size that exceeds the specified size, resulting in welding corners and burrs on the edges of the metal frame. Appropriate trimming and cutting are required, followed by edge grinding to ensure that the prepared metal frame meets the size requirements of the finished product.

[0003] Metal frame trimming mainly adopts two methods: manual cutting and trimming machine cutting. Both processing methods have their own advantages. Traditional trimming machines mainly use fast-running machinery to trim the burrs of metal frames. Although the processing efficiency is high, the fast-moving equipment has a high speed, which easily causes the burrs after cutting to splash everywhere and splash quickly, posing a very large safety hazard; manual cutting is inefficient and is not suitable for mass production.

[0004] Therefore, on the basis of ensuring the normal and smooth trimming of the metal frame, the research purpose of the present utility model is to design a welding metal frame trimming machine that can timely and comprehensively collect the cut metal burrs and effectively prevent the metal burrs from splashing everywhere.

[0031] The cutting assembly comprises a first cutting piece 2 fixedly mounted on the base 1 and a second cutting piece 3 movably mounted on the base 1, wherein the first cutting piece 2 and the second cutting piece 3 are adapted to be arranged left and right, and the edge burrs of the metal frame fixedly mounted on the first cutting piece 2 are broken after the second cutting piece 3 moves downward;

[0032] A driving mechanism, used for driving the second cutting member 3 to move reciprocatingly up and down;

[0033] The adsorption and collection mechanism includes an electromagnet 4 installed on the second cutting piece 3 and facing the first cutting piece 2, and a collecting hopper 5 installed on the base 1 and located below the electromagnet 4. When the second cutting piece 3 moves downward, the electromagnet 4 is energized, and when the second cutting piece 3 moves upward, the electromagnet 4 is de-energized.

[0034] The utility model uses the second cutting piece 3 to reciprocate up and down and then adapt to the first cutting piece 2 to trim the metal frame. When the second cutting piece 3 moves downward, the electromagnet 4 is energized and moves downward with the second cutting piece 3, thereby promptly and quickly adsorbing the cut metal burrs onto the electromagnet 4, effectively preventing the metal burrs from splashing everywhere and improving the processing safety; when the second cutting piece 3 moves upward, the electromagnet 4 is de-energized, and the burrs adsorbed by the electromagnet 4 fall into the collecting hopper 5 in time for collection, and the power-on and power-off frequency of the electromagnet 4 is consistent with the up and down movement frequency of the second cutting piece 3, thereby ensuring that the burrs fall into the collecting hopper 5 in time and one by one, effectively preventing the burrs from accumulating and clogging the collecting hopper 5.

[0035] The second cutting piece 3 is an inverted L-shaped structure consisting of an upright support portion 301 connected to the driving mechanism and a transverse cutting portion 302 adapted to the first cutting piece 2. The connection between the transverse cutting portion 302 and the upright support portion 301 is arranged in a step shape and is locked by corresponding bolts.

[0036] A mounting seat for mounting the first cutting piece 2 is fixedly connected to the base 1 , and the connection between the mounting seat and the first cutting piece 2 is arranged in a step shape and is locked by corresponding bolts.

[0037] The second cutting piece 3 of the utility model is composed of an upright support part 301 and a horizontal cutting part 302 to form an inverted L shape. The second cutting piece 3 is installed on the base 1 by moving up and down using the upright support part 301 to ensure the stability of the movement of the second cutting piece 3 and avoid problems such as deviation, thereby ensuring the quality of cutting; the first cutting piece 2 and the second cutting piece 3 are both stepped at the installation connection and locked by corresponding bolts, which ensures the stability of the installation while facilitating the disassembly and replacement of the first cutting piece 2 and the second cutting piece 3, thereby improving the practical effect.

[0041] The utility model utilizes a crank-connecting rod mechanism to drive the second cutting piece 3 to move up and down. The slider 9 moves up and down along the guide groove 8 under the cooperation of the crank piece 6 and the connecting rod 7 and the drive of the motor 6, which not only ensures that the second cutting piece 3 can move up and down quickly, stably and regularly, but also effectively ensures the cutting quality and practical effect.

[0042] The lower end of the aggregate hopper 5 passes downward through the base 1 and extends to the aggregate frame or the aggregate bag.

[0045] The utility model can also use the cam and top column driving mechanism as a driving mechanism to drive the second cutting piece 3 to move up and down. The rotation of the cam 10 drives the top column 11 to move up and down along the contour of the cam 10. The top column 11 with the elastic member 12 penetrates the base and moves up and down, which not only ensures that the second cutting piece 3 can move up and down quickly, stably and regularly, but also effectively ensures the cutting quality and practical effect.
