Problems solved by technology

The overall strength of the cast fuselage is good, but it is heavy and expensive
The welded fuselage is widely used because of its light weight, less material waste, and low cost. However, during stamping, due to the reaction force, the fuselage body is easily deformed, and even the welded parts are broken, which seriously affects the parts of the fuse...

Abstract

The invention discloses a pressing machine which comprises a welding machine body, wherein reinforcing plates are respectively welded on the two sides of a left wall plate and a right wall plate of the welding machine body; each reinforcing plate comprises a guide rail reinforcing part used for reinforcing the guide rail mounting area, a platform reinforcing part used for reinforcing the area below a working platform, and a middle reinforcing part used for reinforcing the wall plates between the guide rail and the working platform, and the three parts are integrally formed. With the adoption of the technical scheme, the welding body is light in weight, saves materials, and is low in cost, small in deformation if being in long-term heavy-load operation, and low in manufacturing cost.

Example Embodiment

[0017] Example 1:
[0018] Such as figure 1 , figure 2 The press shown includes a welded body. The inner and outer sides of the left and right wall panels 1 of the welded body are welded with reinforcing plates 2. The reinforcing plate 2 includes a guide rail reinforcement 21 for reinforcing the guide rail installation area, and The platform reinforcement part 23 that strengthens the area under the working platform 3 and the middle reinforcement part 22 that strengthens the wall panel between the guide rail 4 and the working platform 3 are connected with the guide rail reinforcement part 21 and the platform reinforcement part 23 as a whole. The widths of the guide rail reinforcement 21, the platform reinforcement 23 and the middle reinforcement 22 of the reinforcement plate 2 are all greater than 30 cm. The thickness of the reinforcing plate 2 is greater than the thickness of the left and right wall panels 1. Guide rails 4 are installed on the inner side reinforcement plates 2 of the left and right wall panels 1, and rail pressing plates 5 are installed on the front of the left and right wall panels 1 and the reinforcement plates 2, and the guide rail pressing plates 5 are connected to the inner reinforcement plates 2 of the left and right wall panels 1 through bolts. Fixed connection.
[0019] Such as image 3 As shown, a single wall panel 1 is used in the prior art. In order to avoid deformation and improve processing accuracy, a thicker material manufacturing method is generally used, which in turn increases the body consumables, the weight of the whole machine, and the production cost. Such as Figure 4 As shown, in the stress concentration area of ​​the fuselage, the present invention is welded with symmetrical reinforcing webs 2 on the inner and outer sides of the left and right wall panels 1, which increases the stiffness, strength and deformation resistance of the fuselage as a whole, and reduces material loss .
[0020] Such as Figure 5 As shown, in the prior art, the press guide rail pressure plate 5 is installed on the narrower fuselage wall panel 1. The installation method of edge side pressure is adopted. Under the action of the force F, the force of the fastening bolts tends to be uneven. , The pressure plate becomes loose, and the sliding block has poor anti-eccentric load performance, and even the guide rail 4 is deformed. Such as Image 6 As shown in the present invention, in the fuselage structure after the inner and outer wall panels are welded to strengthen the web, the contact surface of the guide rail pressing plate 5 is widened, and the fastening bolts are connected at the center position, so that the force is evenly received, and the guide rail pressing plate is more closely connected to the fuselage , It is not easy to loosen, and the anti-eccentric load performance of the slider is strengthened.
[0021] According to the present invention, in the case of long-term load movement of the press, according to the distribution area of ​​the reaction force (stress), a reinforcement plate of a specific shape is welded on the inner and outer sides of the working area of ​​the left and right wall panels of the fuselage. It is connected with the important part of the equipment-the guide rail. The front of the thickened wall panel work area and the guide rail pressure plate can be more effectively connected and fixed. This structure is welded to the fuselage to form a whole, and the main stress area of ​​the fuselage is strengthened. Most of the stresses act on this reinforced structure, increase the overall rigidity, strength and torsion resistance of the fuselage, reduce the deformation of the fuselage under long-term heavy load operation, and strengthen the relationship between the guide rail and the guide rail pressure plate. The strong connection makes the equipment more stable under heavy load movement, improves the accuracy of the product, and extends the service life of the mold and the relevant parts of the body.
[0022] The advantages of the invention are: compared with similar products, the welded fuselage is light in weight, greatly saves materials, reduces production costs, and has good strength, strong torsion resistance, and small deformation of the fuselage under long-term load movement. , To ensure the accuracy of the product, extend the service life of the mold and related parts and other advantages.
