The invention discloses a pre-upsetting machine adaptable to multi-size machining. The pre-upsetting machine comprises an upper panel, an upper outer die sleeve, a lower outer die sleeve, an inner die sleeve, a bottom plate and a clamping block. The upper outer die sleeve and the lower outer die sleeve are connected. The inner die sleeve is located in the upper outer die sleeve and the lower outer die sleeve. The length of the inner die sleeve is equal to the sum of the length of the upper outer die sleeve and the length of the lower outer die sleeve. The upper panel is fixed to the top end of the upper outer die sleeve and the top end of the inner die sleeve. The clamping block is arranged in the bottom plate. The bottom plate is fixed to the bottom end of the lower outer die sleeve and the bottom end of the inner die sleeve. A channel formed by the clamping block communicates with the inner die sleeve. The pre-upsetting machine adaptable to multi-size machining has the beneficial effects that die sleeves are manufactured into the inner and outer die sleeves, the upper outer die sleeve is connected with the upper panel, and the inner die sleeve is manufactured into a switchable inner container according to different products; when the pre-upsetting machine operates, water flow is led into, so that a die is cooled, and the service life of the die is prolonged; and the clamping block adopts the half-and-half V-shaped groove design and can adapt to clamping of a rod material with a certain size.
Description
technical field [0001] The invention relates to a pre-upsetting machine, especially a pre-upsetting machine which can be adapted to processing of various sizes. Background technique [0002] The automobile half shaft is an important part of the automobile chassis, and its product quality will directly affect the safety of the automobile operation, usually through forging. The steel bar is aggregated through the pre-heading machine first, and then formed by pendulum rolling. There are many types of half shafts, and the molds need to be replaced frequently, while the die sets of the pre-heading machine are larger than the half shafts, and frequent replacement of the die sets is more difficult. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pre-heading machine that can be adapted to processing of various sizes. [0004] The present invention is achieved through the following technical solutions. [0005] A pre...
