Description

Technical Field

[0001] The utility model relates to the technical field of hot die forging presses, in particular to an oxide scale removal structure used for hot die forging presses. Background Art

[0002] Hot die forging presses are used for die forging and finishing of large quantities of ferrous and non-ferrous metals in the manufacturing industries of automobiles, tractors, internal combustion engines, ships, aviation, mining machinery, petroleum machinery, hardware tools, etc. When producing containers, it is usually necessary to forge the heated steel billets into shape using hot die forging presses.

[0003] When the existing hot die forging press is in use, the oxide scale produced on the surface of the steel billet will remain on the surface of the hot die forging press and needs to be manually cleaned after forging, which is rather cumbersome. At the same time, the relatively fine oxide scale dust is easy to float into the air during the cleaning process, causing dust pollution. Moreover, after the oxide scale accumulates to a certain thickness, when the steel billet is forged, the surface of the forged steel billet is easily made uneven, resulting in a decrease in the forging quality of the steel billet. Utility Model Content

[0004] The utility model aims to provide an oxide scale removal structure for a hot die forging press to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0011] Furthermore, the air inlet end of the fan is fixedly connected to one end of the multi-directional collecting pipe, and a filter is movably embedded in the outer surface of the multi-directional collecting pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Fix the fixed plate to one side of the hot die forging press body by bolts. The No. 1 motor runs to drive the sliding sleeve to move. The spring pushes the No. 1 scraper and the No. 2 scraper up, so that the lower surface of the No. 1 scraper can scrape the lower die, and the upper surface of the No. 2 scraper can scrape the upper die. The No. 2 scraper first contacts the upper die and scrapes the oxide scale to the surface of the lower die. Then the No. 1 scraper scrapes the oxide scale to the inside of the guide bin. The oxide scale remaining on the surface of the hot die forging press body is scraped off by the scraping component to avoid the uneven forging surface of the steel billet caused by the accumulation of a certain thickness of oxide scale, thereby improving the forging quality of the steel billet and replacing manual cleaning of oxide scale to simplify the cleaning process.

The fan runs to generate suction at the multi-directional collection pipe, sucking in the floating oxide scale dust, which is filtered by the filter. The blocked dust falls into the dust collection pipe when the fan stops running, thereby collecting the finer oxide scale dust in a unified manner to prevent it from floating into the air during the cleaning process and causing dust pollution. After using it for a period of time, slide the limit sleeve to separate the card slot from the card block, turn the handle to drive the rotating rod and the flap to rotate, so that the dust above the flap falls into the collection bin, making the dust easy to handle.

A dust collecting pipe 402 is fixedly embedded and installed on one end of the outer surface of the multi-directional collecting pipe 303.

[0025] Specifically, the scraping component 2 scrapes off the oxide scale adhered to the surface of the upper die and the lower die 101 of the hot forging press body 1, causing it to fall into the material guide bin 3, and then be collected by the collecting component 4. The fan 305 generates suction at the opening of the material guide bin 3, and sucks the floating oxide scale dust into the material guide bin 3, thereby reducing dust pollution.

[0026] Embodiment 1

[0027] like Figure 1-2 As shown, in this embodiment, two fixed plates 201 are symmetrically fixedly installed on the two side surfaces of the hot forging press body 1, and a bolt 202 is movably embedded and installed on the surface of one side of the fixed plate 201. The bolt 202 penetrates the fixed plate 201 and is screwed together with the hot forging press body 1. A motor 204 is fixedly installed on the surface of one side of the fixed plate 201, and the output end of the motor 204 is fixedly connected to the screw rod 203; a slide bar 209 is fixedly installed on one end of the upper surface of the scraper plate 207, and a scraper plate 208 is slidably connected to the outer side of the slide bar 209. The upper surface of the scraper plate 208 is symmetrically provided with a push rod, and the outer sides of the slide bars 206 and 209 are both movably sleeved with springs.

[0028] In this embodiment, for the sake of clarity of description, the bolt 202 is taken as an example in which the bolt 202 penetrates the fixed plate 201 and is screwed together with the hot die forging press body 1. The fixed plate 201 is fixed to one side of the hot die forging press body 1 by the bolt 202. The No. 1 motor 204 is operated to drive the screw rod 203 to rotate. Through the screw connection with the sliding sleeve 205, and under the limiting action of the guide rod fixed between the two fixed plates 201, the sliding sleeve 205 moves along one side of the hot die forging press body 1, and the spring pushes the No. 1 scraper 207 and the No. 2 scraper 208 to move upward. The lower surface of the No. 1 scraper 207 can scrape the lower die 101, and the upper surface of the No. 2 scraper 208 can scrape the upper die. The No. 2 scraper 208 first contacts the upper die to scrape the oxide scale onto the surface of the lower die 101, and then the No. 1 scraper 207 scrapes the oxide scale uniformly into the guide bin 3, so that the oxide scale remaining on the surface of the hot die forging press body 1 is scraped off through the scraping component 2 to avoid the uneven forging surface of the steel billet caused by the accumulation of a certain thickness of oxide scale, thereby improving the forging quality of the steel billet and replacing manual cleaning of oxide scale to simplify the cleaning process.

[0030] During the specific implementation, the No. 2 motor 302 runs to crush the large pieces of oxide scale inside the guide bin 3, and at the same time drives the oxide scale to fall into the collection bin 401. The fan 305 runs to generate suction at the multi-directional collection pipe 303, sucking in the floating oxide scale dust, which is blocked by the filter 304. The blocked dust falls into the dust collecting pipe 402 when the fan 305 stops running, thereby collecting the finer oxide scale dust in a unified manner to prevent it from floating into the air during the cleaning process and causing dust pollution.

[0031] Embodiment 2

[0032] On the basis of the first embodiment, in order to solve the problem that the dust filtered by the filter screen 304 in the first embodiment is inconvenient to handle.

The rotating rod 404 penetrates the dust collecting tube 402 and is rotatably connected to the dust collecting tube 402. A rotating handle 405 is fixedly installed on one end surface of the rotating rod 404; a clamping block 407 is symmetrically fixedly installed on the outer surface of the rotating handle 405, and a connecting rod 409 is symmetrically fixedly installed on the outer surface of the dust collecting tube 402.

[0034] During specific implementation, after using for a period of time, slide the limit sleeve 406 to separate the card slot 408 from the card block 407, rotate the handle 405, drive the rotating rod 404 and the flap 403 to rotate, and let the dust above the flap 403 fall into the collection bin 401, so that the dust can be easily handled. Then reset the limit sleeve 406, reset and fix the flap 403, close the dust collecting pipe 402, and move the air in a specific direction.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
