Description

Technical Field

[0001] This utility model relates to the field of surface grinding technology, specifically a surface grinding machine for dressing mold steel. Background Technology

[0002] A surface grinder is a type of grinding machine that uses a rotating grinding wheel to grind workpieces to achieve the required flatness. Based on the shape of the worktable, it can be divided into two types: rectangular worktable and circular worktable. The main parameters of a rectangular worktable surface grinder are the width and length of the worktable, while the main parameter of a circular worktable is the diameter of the worktable surface.

[0003] A surface grinder, as disclosed in authorization announcement number CN222095552U, includes a bed, a table fixedly connected to the top of the bed, a column on the top of the table, a mounting seat on the front of the column, a grinding wheel mounted on the front of the mounting seat, a fixing frame sleeved around the column, a fixing frame fixedly connected to the side of the mounting seat, a threaded rod passing through the inside of the fixing frame, a nut threaded onto the outside of the threaded rod, and a scale plate mounted on the side of the column. The beneficial effects of this invention are as follows: when the worktable moves the workpiece left and right, the grinding debris falls onto the top of the workpiece. The scraper can move close to the top of the workpiece, and when the worktable moves the workpiece to the far left or far right, the scraper removes the debris from the top of the workpiece, eliminating the need for manual cleaning of the workpiece surface and making it more convenient to use.

[0004] Although the aforementioned patent can remove debris from the top of the workpiece using a scraper, the lower end face of the scraper is in direct, rigid contact with the upper end face of the mold steel without any elastic buffer. This leads to excessive wear during sliding friction. After long-term use, the scraper may deform due to frictional wear, which may even affect the scraping effect. Moreover, the polished area is lower than the unpolished area, forming a stepped height difference. However, the scraper is at a fixed height, which means that the scraper may be suspended in the polished recessed area and cannot effectively contact the debris. When it moves to the unpolished area, the scraper is suddenly pressed, causing equipment vibration or noise. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3 As shown, this utility model provides a technical solution:

[0025] A surface grinder for dressing mold steel includes a bed 1, with a worktable 2 movably mounted on its upper end. A dovetail groove fixture is fixedly installed in the middle of the inner side of the worktable 2. A vertical column 3 is fixedly installed in the middle of the back of the bed 1. A mounting base 4 is movably mounted on the front of the column 3. A grinding wheel 5 is mounted on the front of the mounting base 4 via a grinding motor. A baffle 6 is provided on the front of the mounting base 4 and outside the grinding wheel 5. Scraping mechanisms are provided on both sides below the baffle 6. The scraping mechanisms include symmetrically fixed... The lower end of the scraper 9 is horizontal to the bottom end of the grinding wheel 5. A horizontal crossbar 10 is fixedly connected to the middle of both sides of the baffle 6. A pressure rod 11 is movably sleeved in the middle of the crossbar 10. The top end of the pressure rod 11 extends to the outside of the crossbar 10 and is fixedly connected to a dial 12. A pressure plate 13 is fixedly connected to the bottom end of the pressure rod 11. A spring 14 is elastically connected between the pressure plate 13 and the crossbar 10 and located outside the pressure rod 11.

[0026] In this embodiment, the scraper 9 and the spring 14 work together to achieve automatic adaptive pressing of the scraper 9 onto the surface of the grinding wheel 5 and the workpiece grinding area. This effectively solves the problems of vibration, noise and excessive wear caused by traditional rigid scrapers in the height difference transition area, and significantly improves the chip removal stability and scraper service life.

[0027] like Figure 1 and Figure 3As shown, a filter box 7 is fixedly installed on the outside of the bottom right side of the bed 1. A spray mechanism is provided between the filter box 7 and the baffle 6. The spray mechanism includes a corrugated pipe 15 connected to the top of the filter box 7 and a pipe 16 connected to the upper right side of the baffle 6. The other end of the corrugated pipe 15 is connected to the worktable 2. One end of the pipe 16 located inside the baffle 6 is connected to a nozzle 17. The other end of the pipe 16 is connected to a circulation pump through a corrugated pipe 20. The end of the circulation pump away from the pipe 16 is connected to the filter box 7. The spray mechanism also includes a placement groove 18 opened inside the upper part of the filter box 7. A filter box 19 is movably installed inside the placement groove 18.

[0028] In this embodiment, the efficient recycling of coolant and real-time filtration and removal of wear debris are achieved through the coordinated operation of the circulating pump, filter box 7, and filter cartridge 19 of the spray mechanism.

[0029] In this embodiment, the surface grinder for dressing mold steel is an improvement on the existing MD250 electric surface grinder. Its working principle is as follows: When dressing mold steel is required, the workpiece to be processed is fixed on the dovetail groove fixture of the worktable 2. The grinding motor is started to drive the grinding wheel 5 to rotate at high speed. Simultaneously, the worktable 2 reciprocates along the upper end of the bed 1 to bring the workpiece into contact with the grinding wheel 5 for grinding. During grinding, the scrapers 9 located below both sides of the baffle 6 are kept in elastic contact with the surface of the grinding wheel 5 by the preload of the spring 14. When there is a height difference between the ground and unground areas, the spring 14 can automatically adjust the clamping of the scrapers 9. Force is applied to avoid excessive wear caused by rigid contact; when the scraper 9 moves to the grinding recessed area, the spring 14 extends to make the scraper 9 move down to maintain contact with the bottom of the groove, while when it moves to the ungrinded area, the spring 14 compresses to buffer the impact force, thereby ensuring that the scraper 9 always effectively removes debris and does not generate equipment vibration; the circulating pump of the spray mechanism delivers the coolant in the filter box 7 through the pipe 16 to the nozzle 17 inside the baffle 6 to spray out, cooling and rinsing the contact area between the grinding wheel 5 and the workpiece. The used coolant carries the grinding debris back to the bellows 15 through the worktable 2 and enters the filter box 7. After the grinding debris is separated by the filter box 19, it re-enters the circulation.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
