A thermal workpiece surface protection device

Abstract

This invention provides a surface protection device for hot workpieces, relating to the technical field of protection devices. The device includes a protective component comprising a housing, an air inlet pipe, and a guide rod. The housing has a hollow internal structure. After heating to a certain temperature, rotating an adjusting screw causes the receiving plate to retract the workpiece into the housing, bringing two sets of sliding plates together and sealing the top of the housing. This design allows the workpiece to be removed from the equipment without hoisting, preventing it from occupying processing space and ensuring its sealed preservation, thus reducing oxidation. This solves the problem of existing hot workpiece forging devices lacking protective structures. After heating, the workpiece needs to be kept warm, but during this process, the heating device cannot process other workpieces. Hoisting the workpiece out at this time can easily exacerbate oxidation, causing slag formation and reducing workpiece quality.

Description

Technical Field

[0001] This invention relates to the field of protective device technology, and in particular to a surface protection device for hot workpieces. Background Technology

[0002] Currently, in the forging workshops of various steel metallurgical processing enterprises, forging equipment is frequently used in the production of steel products. Usually, before forging products, the billet is heated to a temperature of 1100℃ to 1200℃ and held at that temperature for more than 5 hours. After heating and holding to the required temperature, the billet is lifted out of the furnace for forging, so that the billet reaches the required forging size.

[0003] For example, application number CN202110784664.1 discloses a double-column forging machine, including a main housing, a hammer head seat on the upper side of the main housing, a reciprocating triggering mechanism inside the hammer head seat, and three baffle mechanisms inside the main housing. This invention uses the baffle mechanisms to drive the inner and outer baffles upwards to the underside of the hammer. The inner and outer baffle springs within the baffle mechanisms allow the hammer to move the inner and outer baffles downwards together during forging, so that the metal material being forged is surrounded by the three baffle mechanisms, the hammer, and the forging process. This effectively prevents high-temperature oxide scale from splashing during forging, greatly improving operator safety and avoiding damage to the baffle mechanisms from rigid impacts of the hammer. Furthermore, the baffle mechanisms automatically retract each time the hammer retracts after striking the metal, facilitating operator observation of the metal material's condition and improving forging efficiency.

[0004] However, existing hot workpiece forging equipment lacks a protective structure. After the workpiece is heated, it needs to be kept warm. However, during the warming process, the heating device cannot continue to process other workpieces. If the workpiece is lifted out at this time, it will easily aggravate the oxidation of the workpiece, causing it to oxidize and slag, thereby reducing the quality of the workpiece. In addition, existing hot workpiece forging equipment lacks a structure for cleaning metal slag. After the metal slag oxidizes and falls off, it will adhere to the equipment and affect the quality of the workpiece after the next processing. However, the temperature of this metal slag is too high and it is inconvenient to clean it in time. Summary of the Invention

[0010] In at least some embodiments, the protective component further includes: a front groove, a safety block, and a locking plate; the front groove is located at the bottom front side of the housing, and the upper end of the front groove is connected to the interior of the housing; the safety block is slidably installed in the front groove by an elastic element, and the upper end of the safety block is located inside the housing, and a rectangular through hole is provided inside the safety block; the locking plate is inserted into the front groove, and the locking plate passes through the rectangular through hole inside the safety block.

[0011] In at least some embodiments, the protective component includes a rear groove and a telescopic block; the rear groove is located in the middle of the rear side of the housing and is connected to the interior of the housing; the telescopic block is slidably installed in the rear groove by an elastic element, and the end of the telescopic block extends out of the rear groove.

[0012] In at least some embodiments, the cleaning component includes: a movable frame and connecting blocks; the movable frame is a rectangular ring structure; there are two sets of connecting blocks, and the connecting blocks are symmetrically arranged at the bottom ends on both sides of the movable frame.

[0013] In at least some embodiments, the cleaning component further includes: a fixing groove and a scraper; the fixing groove is located in the middle of the rear side interior of the movable frame; the scraper is fixedly installed on the inner end of the front side of the movable frame.

[0014] This invention provides a surface protection device for hot workpieces, which has the following beneficial effects:

[0015] 1. This invention incorporates protective components. Sliding plates with wedge-shaped structures are slidably installed in the side grooves at both ends of the housing. A receiving plate is movably installed at the inner end of the housing via an adjusting screw. The sliding plates are pushed against the two ends of the receiving plate by an elastic element. During use, the workpiece can be placed on the upper end of the receiving plate for forging and heating. Once a certain temperature is reached, rotating the adjusting screw causes the receiving plate to retract the workpiece back into the housing, bringing the two sets of sliding plates closer together and sealing the top of the housing. This design eliminates the need for hoisting to remove the workpiece from the equipment, prevents the workpiece from occupying processing space while in a heated state, and ensures the workpiece is sealed and preserved, thereby reducing oxidation reactions.

[0016] 2. This invention incorporates protective and cleaning components. A large movable frame is slidably installed inside the housing via an elastic element, and a scraper is mounted on the movable frame. The fixed groove inside the movable frame engages with the telescopic block, thus fixing the movable frame within the housing. When it is necessary to clean the metal slag on the receiving plate, the retractable plate is removed, allowing the safety block to freely extend and retract within the front groove. By rotating the adjusting screw, the receiving plate is moved to the lowest side of the housing, pressing it against the telescopic block and retracting it into the rear groove. The movable frame, now free of its limiting position, is pushed out of the housing by the elastic element, and the scraper moves along the upper surface of the receiving plate to scrape the metal slag. In this way, the removal of metal slag is completed without manual intervention. Attached Figure Description
