Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold-bent steel processing technology, specifically to a device for removing burrs from the edges of four-sided cold-bent steel. Background Technology
[0002] In the production and processing of cold-formed steel, the removal of sharp edges and burrs is a crucial step. Traditionally, this is done manually using an angle grinder. However, this method has several significant disadvantages.
[0003] First, from the perspective of processing efficiency, manually operating an angle grinder is slow. Workers need to hold the angle grinder and grind each edge of the cold-formed steel piece by piece, a tedious and time-consuming process. Taking a typical industrial production scale as an example, if a large number of cold-formed steel parts of the same specifications need to be processed, manual grinding cannot keep up with the production pace, severely restricting overall production efficiency and making it difficult for companies to complete orders within the specified time, thus increasing time costs.
[0004] Secondly, in terms of processing precision, manual grinding is difficult to guarantee consistency. Different workers have varying levels of skill, control over force, and mastery of grinding angles, resulting in significant differences in the chamfer dimensions and shapes even among cold-formed steel from the same batch after manual grinding. This inconsistency in precision greatly impacts the subsequent assembly process of the cold-formed steel, potentially causing assembly difficulties, excessive gaps, and reducing the overall quality of the product, even affecting its performance and safety. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] The technical problem this invention aims to solve is the low efficiency and inconsistent grinding quality caused by the traditional manual use of angle grinders for grinding burrs.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0036] Please see Figures 1-5 The device shown is a four-sided cold-bent steel edge and burr removal device, which includes a feeding device 1, a chamfering device 2, a material transfer device 3 and a frame 4.
[0037] The equipment frame 4 serves as the basic support structure for the entire device. It is welded from high-strength steel and has sufficient rigidity and stability to ensure that it will not shake or deform during the operation of the device, providing a reliable installation platform for the feeding device 1, the chamfering device 2, and the material transfer device 3.
[0038] The feeding device 1, the chamfering device 2, and the conveying device 3 are all mounted on the equipment frame 4. The chamfering device 2 is located between the feeding device 1 and the conveying device 3 to remove the burrs from the edges of the cold-formed steel. The feeding device 1 is used to convey the cold-formed steel that needs to have its edges and burrs removed to the chamfering device 2 for burr removal. The conveying device 3 is used to convey the cold-formed steel that has had its burrs removed to the next work station.
[0039] The feeding device 1 consists of a pressing component 101, a moving component 102, and a plate chain conveyor 103. The moving component 102 is fixedly mounted on the plate chain conveyor 103. The moving component 102 includes a support frame 102a and a semi-enclosed belt module 102b. The support frame 102a is welded from channel steel and is fixedly connected to the frame of the plate chain conveyor 103, providing stable support for the semi-enclosed belt module 102b. The semi-enclosed belt module 102b is mounted on the upper end of the support frame 102a. The pressing component 101 is connected to the moving component 102. The pressing component 101 includes a crossbeam 101a and rollers 101b. The crossbeam 101a has a "T"-shaped cross section and is integrally cast from steel. This structural design gives it excellent bending strength. It is fixed to the sliding body on the semi-enclosed belt module 102b by welding, ensuring reliable connection. Roller 101b is connected to crossbeam 101a via a bearing connector with bolts. The surface of roller 101b is covered with a rubber layer, which can effectively press down on the cold-bent steel to prevent it from jumping during the conveying process, and also avoid scratching the surface of the cold-bent steel.
[0040] The moving component 102 drives the pressing component 101 to move back and forth, flexibly adapting to the processing requirements of cold-formed steel of different lengths. When dealing with shorter cold-formed steel, the semi-enclosed belt module 102b in the moving component 102 receives instructions from the control system and drives the pressing component 101 connected to it to move forward, precisely adjusting its position so that the roller 101b of the pressing component 101 presses precisely on the appropriate part of the cold-formed steel, ensuring that the cold-formed steel remains stable at the beginning of the conveying process. When encountering longer cold-formed steel, the semi-enclosed belt module 102b operates in the opposite direction, driving the pressing component 101 to move backward, also precisely positioning it to ensure that the roller 101b can effectively press down on the cold-formed steel. This prevents the cold-formed steel from shifting or swaying during the conveying process, laying a solid foundation for subsequent chamfering processing and effectively ensuring the stability of the conveying process.
[0041] The chamfering device 2 includes a square upright plate 201 and grinding components 202. The upright plate 201 is fixedly mounted on the equipment frame 4 by angle iron, ensuring the firmness and stability of the upright plate 201 installation. The upright plate 201 also has square holes 203 to facilitate the passage of cold-formed steel. The size of the square holes 203 is designed according to the specifications of common cold-formed steel, slightly larger than the cross-sectional dimensions of the cold-formed steel. This ensures the smooth passage of the cold-formed steel while also providing a certain degree of restraint, preventing the cold-formed steel from shifting during grinding. Four grinding components 202 are provided, arranged opposite each other along the two diagonals of the upright plate 201, ensuring that all four edges of the cold-formed steel can be ground simultaneously.
[0042] The grinding assembly 202 includes a connecting base plate 202a, a skateboard base 202b, a skateboard 202c with threaded holes 202k, a drive motor 202d, a grinding disc 202e, a connecting block 202f, a hand crank 202g, and a drive rod 202h. The connecting base plate 202a is made of stainless steel and is welded to the upright plate 201 to ensure connection strength. The skateboard base 202b is fixedly mounted on the connecting base plate 202a and has a dovetail groove 202j. The skateboard 202c is positioned in the dovetail groove 202j and can slide within it. The drive motor 202d is fixedly mounted on the upper surface of the skateboard 202c and can slide along with the skateboard 202c. The drive motor 202d is a variable frequency motor with appropriate power, capable of adjusting its speed according to different grinding requirements. The grinding disc 202e is connected to the shaft of the drive motor 202d to grind the edges of the cold-formed steel. The material of the grinding disc 202e is selected according to the material and hardness of the cold-formed steel. For example, for cold-formed steel with higher hardness, a diamond-coated grinding disc is selected to ensure the grinding effect. The connecting block 202f is fixedly installed on one side of the skateboard base 202b. The connecting block 202f is welded to the skateboard base 202b to form an integral part, ensuring a firm connection. The drive rod 202h is threaded. One end of the drive rod 202h is connected to the connecting block 202f via a bearing and extends to its outer side to connect with the hand crank 202g. The bearing is a high-precision ball bearing to reduce rotational friction. The other end of the drive rod 202h is threadedly connected to the threaded hole 202k on the slide plate 202c. The threaded hole 202k is coaxial with the drive rod 202h, ensuring that the drive rod 202h can smoothly push the slide plate 202c to move when rotating, thereby precisely adjusting the position of the grinding disc 202e. When the position of the grinding disc 202e needs to be adjusted, the operator rotates the hand crank 202g, and the drive rod 202h rotates accordingly. Due to the threaded engagement, the slide plate 202c slides in the dovetail groove 202j, causing the grinding disc 202e to move closer to or away from the cold-formed steel edge, achieving precise adjustment. In addition, locking holes 202m are provided on both sides of the slide base 202b. These holes are used to fix the position of the slide 202c after the drive motor 202d has been adjusted. During the grinding process, the locking pin is inserted into the locking hole 202m to ensure that the slide 202c will not shift, thus improving the grinding accuracy. The material conveying device 3 adopts a plate chain conveyor.
[0043] Working principle:
[0044] The cold-formed steel to be processed is placed on the plate chain conveyor 103 of the feeding device 1, and the plate chain conveyor 103 is started. At the same time, the moving component 102 drives the pressing component 101 to move to a suitable position according to the length of the cold-formed steel through the semi-enclosed belt module 102b, so that the roller 101b of the pressing component 101 gently presses down on the cold-formed steel, ensuring that the cold-formed steel will not warp or shift during the conveying process, and is smoothly conveyed to the chamfering device 2.
[0045] When the cold-formed steel reaches the chamfering device 2, the operator adjusts the position of the grinding disc 202e by rotating the handwheel 202g according to the condition of the cold-formed steel's edges. For example, if a thick burr is found on a certain edge, the corresponding grinding disc 202e is moved closer to the edge by rotating the handwheel 202g. After adjustment, the locking pin is inserted into the locking hole 202m of the skateboard base 202b to fix the position of the skateboard 202c. Next, the drive motor 202d is started, which drives the grinding disc 202e to rotate at high speed, simultaneously grinding the four edges of the cold-formed steel to remove the burr. During the grinding process, due to the limiting effect of the upright plate 201 and the fixing effect of the skateboard base 202b, the grinding disc 202e can stably and accurately work on the edges, ensuring the grinding quality.
[0046] After grinding, the cold-formed steel continues to move forward, passing through the square hole 203 in the vertical plate 201 and entering the material conveying device 3. The plate chain conveyor of the material conveying device 3 smoothly transports the processed cold-formed steel to the next workstation for subsequent processing or packaging, ensuring the smooth operation of the entire production process.
[0047] In summary, the four-sided cold-bent steel chamfering device of this utility model, through the careful design and coordinated operation of its various components, can efficiently and accurately remove the burrs from the edges of cold-bent steel, improve product quality, and meet the needs of industrial production.
