Description

Technical Field

[0001] This utility model belongs to the field of cold-rolled strip steel processing technology, and relates to a pretreatment device for cold-rolled strip steel before pickling. Background Technology

[0002] Cold-rolled strip steel is a strip steel product manufactured through a cold rolling process. It features relatively precise dimensional accuracy and good surface quality. For cold-rolled strip steel, pickling is performed to remove impurities such as iron oxide scale and rust from the surface, thus making the strip steel surface cleaner and creating favorable conditions for subsequent processing.

[0003] In existing technologies, before pickling cold-rolled strip steel, manual hand-held grinders are typically used to pre-treat specific areas of the strip steel to remove substances that may hinder the pickling process. However, due to the width of the cold-rolled strip steel and the safety hazards associated with manual operation close to the conveying strip, this method is problematic. Therefore, designing a pre-treatment device for cold-rolled strip steel before pickling to address these issues is essential. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pretreatment device for cold-rolled strip steel before pickling.

[0005] To achieve the above objectives, the technical solution of this utility model is: a pretreatment device for cold-rolled strip steel before pickling, comprising two columns, one of which is fixed with a main support seat, the main support seat having an clearance groove, and the other column is fixed with an auxiliary support seat. A movable crossbeam is slidably connected between the auxiliary support seat and the main support seat. A cylinder is fixed in the middle of the movable crossbeam via a mounting seat, and the piston rod of the cylinder is vertically downward. The end of the piston rod of the cylinder is fixedly connected to the body of the grinding machine. Multiple handles are fixed on the end of the movable crossbeam near the main support seat.

[0006] Both ends of the mounting base are fixed with elastic limiting blocks.

[0007] The mounting base is also fixed with a positioning rod, and a laser pointer tilted downwards is fixed on the positioning rod.

[0008] The body of the grinder is fixed to the end of the piston rod of the cylinder by a connecting block assembly.

[0009] The main support is also equipped with a control box for controlling the cylinder and the action of the grinder.

[0010] By adopting the above technical solution, the beneficial effects of this utility model are: This invention features two columns with a main support and an auxiliary support fixed to them. A movable crossbeam is slidably connected between the two columns. Operators can push the movable crossbeam along the width of the strip steel to move it smoothly, thereby driving the grinding machine to pre-treat different transverse positions of the strip steel. This effectively solves the problem of limited operating range of manual handheld grinding machines and is especially suitable for cold-rolled strip steel with a certain width.

Detailed Implementation

[0012] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0013] like Figure 1-2 As shown, this pretreatment device for cold-rolled strip steel before pickling includes two columns 1. A main support 4 is fixed on one column 1, and a clearance groove 4a is provided on the main support 4. An auxiliary support 8 is fixed on the other column 1. A movable crossbeam 7 is slidably connected between the auxiliary support 8 and the main support 4. A cylinder 3 is fixed to the middle of the movable crossbeam 7 through a mounting seat 9, and the piston rod of the cylinder 3 is vertically downward. The end of the piston rod of the cylinder 3 is fixedly connected to the body of the grinding machine 2. With this structure, the cylinder 3, which is fixed in the middle of the movable crossbeam 7 via the mounting base 9, has its piston rod vertically connected to the body of the grinding machine 2. When grinding is required, the grinding wheel of the grinding machine 2 contacts the surface of the cold-rolled steel strip. The cylinder 3 achieves the height adjustment of the grinding machine 2 using existing technology. At the same time, it ensures that the pressure applied during the grinding process is stable and controllable, avoiding uneven pressure during manual operation. Multiple handles 6 are fixed on one end of the movable crossbeam 7 near the main control seat 4. With this structure, when adjusting the position of the grinding machine 2, the required handle 6 can be held. During grinding, the corresponding handle 6 can also be manually pulled to make the grinding machine 2 reciprocate within a certain range.

[0014] Both ends of the mounting base 9 are fixed with elastic limiting blocks 10.

[0015] The mounting base 9 is also fixed with a positioning rod 12, and a downward-sloping laser pointer 11 is fixed on the positioning rod 12. The downward-sloping laser pointer 11 is designed to project a clear light spot on the surface of the strip steel, helping operators to quickly and accurately locate the grinding area.

[0016] The body of the grinder 2 is fixed to the end of the piston rod of the cylinder 3 by a connecting block assembly.

[0017] The main seat 4 is also equipped with a control box 5 for controlling the operation of the cylinder 3 and the grinder 2. This adopts existing technology and can control the operation of the cylinder 3 and the grinder 2.

[0018] In this invention, two columns 1 are set up, and a main support 4 and an auxiliary support 8 are fixed on the columns 1 respectively. A movable crossbeam 7 is slidably connected between the two. The operator can push the movable crossbeam 7 to move smoothly along the width of the strip steel through the handle 6, thereby driving the grinding machine 2 to pre-treat different transverse positions of the strip steel. This effectively solves the problem of limited operating range of the manually handheld grinding machine 2, and is especially suitable for cold-rolled strip steel with a certain width. In practice, after adjusting the position of the grinding machine 2, the grinding machine 2 is moved downward to contact the cold-rolled strip steel.

[0019] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0020] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
