Description
Technical Field
The utility model relates to a punch press technical field, in particular to punch press lathe bed of integral structure.
background
at present, most punching machines have structures that a lathe bed is divided into five parts, namely a crankcase and four middle section upright posts, wherein each middle section upright post is connected with the crankcase by four M20 screws, and is connected with a base by four M20 screws. Because the locking force of each screw is uneven, the parallelism and the verticality of the plane of the middle-section upright post are influenced. Thereby causing an error in which the punching accuracy is unstable at the time of punching.
The four slide block guide posts are only arranged on the middle section upright post. The working surface of the table plate is arranged on the base, and the levelness of the planes of the four middle-section upright columns and the central shafts of the base holes at the two ends of the crankshaft of the crankcase cannot be ensured; and the parallelism between the planes of the four middle-section stand columns and the plane of the base platform placing plate can not be ensured.
The crank shaft, the bearing, the connecting rod, the copper shoe, the balance block, the adjusting screw, the flywheel, the brake clutch and other key parts and important parts are arranged in the crank shaft box;
The middle section is provided with key parts and important parts such as a slide block, a slide block guide post, a slide block guide sleeve, a die height adjusting gear pair, a square shaft and the like;
The six parts of the crank case, the four middle section upright posts and the base are combined into a whole by using 32-M20 screws.

Because the three parts are combined into a whole, the existence and increase of machining errors and coordinate errors are brought, and the precision requirement of the whole machine after the gantry precision high-speed punch press is assembled cannot be met.
Some manufacturers also adopt a welded structure, or main castings adopt low-grade 'HT-150, 200 or 250' gray cast iron, and cast 'crank cases', 'middle sections' and 'bases'; the adoption of gray cast iron has the defects of poor shock resistance, loose material, low hardness, poor wear resistance and the like; the welding structure has unbalanced internal stress, the internal stress is not easy to completely release, the machine body is not integrated, and the welding joint is connected. The strength of the machine body is insufficient, the machine body can be slowly deformed when the internal stress is continuously released, and the 'precision' of the equipment can be continuously reduced; improvements are therefore needed.
