Description

Technical Field

[0001] The invention belongs to the technical field of metal forging, and in particular relates to a forging device for helmet metal accessories and a use method thereof. Background Art

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation in order to obtain a forging with certain mechanical properties, shape, and size. Forging can eliminate defects such as cast porosity produced during the metal smelting process and optimize the microstructure. At the same time, because the complete metal flow lines are preserved, the mechanical properties of the forging are generally better than those of castings of the same material.

[0003] Before calcining the metal blanks, they need to be neatly arranged in a calcining furnace. After calcining, they are taken out one by one for pressure forming. Since the metal accessories of the helmet are small, more metal accessories can be calcined at one time. If they are placed one by one in the calcining furnace, the loading efficiency will be low. When the metal blanks after segment calcination are taken out, the heat of other metal blanks in the calcining furnace will be dissipated faster. In order to solve the above problems, a helmet metal accessories forging device and a use method thereof are provided.

[0059] A method for using a helmet metal accessory forging device comprises the following steps:

[0060] S1: placing the metal blank into a calcining furnace 1 for quenching treatment;

[0061] The furnace cover 5 is pulled out of the calcining furnace 1 by contracting the first cylinder 4, and the placement rack body 61 is taken out of the calcining furnace 1 at the same time, and then the metal billet is poured onto the placement rack body 61, and the metal billet on the placement rack body 61 can be quickly shaken and evenly mixed by starting the second motor 63 to avoid accumulation, and then the first cylinder 4 is extended to cover the furnace cover 5 on the calcining furnace 1, so that the metal billet enters the calcining furnace 1 for quenching treatment.

[0062] S2: clamping the quenched metal blank onto the hydraulic platform 9 for forging into the required helmet metal parts;

[0063] By controlling the length of the first cylinder 4, the withdrawal length of the placement rack body 61 can be controlled, so that a small part of the metal blank can be located outside, so as to avoid the material on the placement rack body 61 from cooling too quickly during the forging process. The position of the clamp is adjusted by the third motor 84 and the second cylinder 85 to be located above the placement rack body 61 outside. The position of the clamp is further adjusted so that the second distance sensor 816 can detect that there is a metal blank below it. The clamp is controlled to descend by starting the third cylinder 86 so that the two clamps 815 are respectively located on both sides of the corresponding metal blank. By contracting the fourth cylinder 812, the two clamps 815 are moved closer to each other under the action of the third spring 810, so as to achieve forging of the metal blank. The material is clamped, and the metal blank is transferred to the placement table 95 through the cooperation of the third motor 84, the second cylinder 85 and the third cylinder 86. The metal blank can be adjusted to rotate along the horizontal axis by starting the fifth motor 814. After the metal blank is placed on the placement table 95, the metal blank can be controlled to rotate along the vertical axis by starting the fourth motor 94. Therefore, the position of the metal blank placed on the placement table 95 can be arbitrarily adjusted by the cooperation of the clamp and the fourth motor 94. The metal blank is pressed by starting the hydraulic cylinder 96 to control the pressing plate 97. The pressing position can be adjusted by the cooperation of the third motor 84 and the second cylinder 85 until the metal blank is pressed to form the required helmet metal accessories, thereby realizing the forging of helmet metal accessories.

[0064] When the inner wall of the calcining furnace 1 needs to be cleaned, the placement rack body 61 is placed in the calcining furnace 1. Under the action of the second spring 66, the scraper 64 contacts the inner wall of the calcining furnace 1. By starting the second motor 63 to control the rotation of the placement rack body 61, the scraper 64 is driven to scrape the inner wall of the calcining furnace 1 to make the stains on it fall off. After scraping is completed, the fallen stains are sucked out of the calcining furnace 1 by a vacuum cleaner.

[0065] When it is necessary to repair or clean stubborn stains in the calcining furnace 1, the rack body 61 is rotated to a horizontal position, the equipment for repair or cleaning is placed on the rack body 61, and the telescopic plate 73 is placed above the equipment for repair or cleaning. Figure 4As shown, the two fixing seats 71 are respectively slid into the sliding grooves 67 on the side walls of the placement rack body 61, the electric telescopic rod 713 is adjusted so that the connecting piece 715 is located above the insertion rod 722, the fixing seat 71 is moved so that the insertion hole 716 is located directly above the insertion rod 722, and the electric telescopic rod 713 is retracted to fix the equipment used for maintenance or cleaning between the fixing member 72 and the placement rack body 61, and the first cylinder 4 is started to send the placement rack body 61 fixed with the maintenance or cleaning equipment into the calcining furnace 1 to repair or clean the inner wall. The placement rack body 61 can be controlled to rotate by driving the second motor 63, so that the maintenance or cleaning equipment can clean or repair all directions in the calcining furnace 1, and the telescopic plate 73 is set to fix maintenance or cleaning equipment of any size.

[0066] When the fixing device 7 is idle, the two fixing seats 71 can be placed on the ground with the electric telescopic rod 713 facing upwards, and the insertion rod 722 on the fixing piece 72 is inserted from above into the corresponding insertion hole 716, and objects can be placed on the fixing plate 721. The length of the telescopic plate 73 can be adjusted according to the size of the placed objects. By adjusting the height of the electric telescopic rod 713, the height of the placed objects can also be adjusted. When the arc-shaped depression on the telescopic plate 73 is downward, it can also be used as a bench for people to rest. When the arc-shaped depression on the telescopic plate 73 is upward, cylindrical objects can be placed to prevent them from rolling down.

[0067] When the rack assembly 6 is discarded, the two fixing seats 71 can be placed on the ground, and the discarded rack assembly 6 is placed on the two fixing seats 71, and the side walls of the rectangular frame are placed in the U-shaped placement grooves 714 on the two fixing seats 71, respectively. Figure 6 As shown, the rack assembly 6 can be used as a temporary support for placing items. By extending one of the electric telescopic rods 713, the rack assembly 6 can be controlled to swing left and right to flatten the items on it to avoid accumulation. At this time, the scraper 64 can also be used as a protective plate. When the slide plate is hit, the second spring 66 can be used to buffer the items on the rack assembly 6 to prevent them from falling off.

[0068] Alternatively, the two end side walls of the rectangular frame may be placed in the U-shaped placement grooves 714 on the two fixing seats 71, as shown in FIG. Figure 7 As shown, extending one of the electric telescopic rods 713 can cause the rack assembly 6 to tilt. When the truck needs to unload materials, it can be placed next to the truck and the goods can be slid off the rack assembly 6 to achieve unloading. This unloading method not only saves manpower, but also avoids damage to the goods or the ground caused by the goods falling directly from the truck to the ground.

[0069] The rack assembly 6 can also be placed vertically to serve as a guardrail. Figure 8As shown, the two fixed seats 71 are both slid into the sliding groove 67 below, one end of the insertion rod 722 is inserted between two adjacent support bars, the two fixed seats 71 are moved so that the socket 716 corresponds to the insertion rod 722, and the electric telescopic rod 713 is retracted so that the insertion rod 722 is inserted into the corresponding socket 716, thereby fixing the placement rack assembly 6 and preventing it from sliding left and right on the fixed seat 71.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
