Problems solved by technology

This kind of vertical drawing press has good rigidity and relatively compact structure, but it cannot solve the scale problem. Because the scale of the billet falls down when the vertical drawing press is drawn, it is easy to press on the surface of the bottle, causing The wall thickness of the preform is uneven, and the surface quality is not high, and the surface quality is an important indicator of the performance of the high-pressure gas cylinder, which will directly affect the service life and sales of the product
In addition, due to the long drawing stroke, the height of the fuselage is very high, which is very inconvenient for installation, debugging and maintenance. It is very deep, and the foundation of the pit is not easy to construct and it is difficult
The use of the whole frame makes the welding process more complicated, and the residual stress of the frame needs to be eliminated

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] As shown in Figure 1 and Figure 2, the horizontal drawing hydraulic press. It has frame, main working cylinder 1, return cylinder 2, moving beam 3, front beam 4, rear beam 5, bottom mold beam 6, return cylinder plunger 7, return beam 8, feeding manipulator 9, bracket device 10, Lifting material platform 11, base beam 12, anchoring device 13, positioning sleeve 14, nut 15, drawing mandrel seat 16, drawing mandrel 17, buffer cylinder 19, bottom mold base, and bottom mold 20, etc., the whole machine is The horizontal layout is a beam-column prestressed composite frame.

[0033] The frame is a closed prestressed frame composed of the back beam 5, the front beam 4 and the tie rods used as the return cylinder 2; the two return cylinders also serve as tie rods, and their two ends are fixed with the front beam and the back beam with nuts, between the front beam and the...

Abstract

The horizontal traction water hydraulic machine comprises the bay, main working cylinder, kicker cylinder, active beam, front beam, rear beam, bottom mold beam, kicker beam and base beam, featuring in the horizontal arrangement, prestress combined bay, two side kicker cylinders also working as the pulling post, forming into rigid force bearing frame with the front and rear beams and the bay, small stress fluctuation of the pulling post under the working load and small displacement of the front beam, ensuring the undeviation of the presser symmetrical line, good overall rigidity, high precision of alignment precision of the presser, acquiring extracting bottle blank with higher concentricity. It also has bracket system, alighting material platform, material discharging device and blanking robot.

Description

1. Technical field [0001] The invention belongs to drawing equipment for producing thin-walled cylindrical products, specifically a horizontal drawing hydraulic press specially used for producing high-pressure oxygen cylinders, natural gas cylinders and the like. 2. Background technology [0002] The drawing press is a device used to perform "thinning and stretching" (drawing) plastic processing of the cup-shaped preform. The existing drawing and stretching presses are all vertical structures: a whole welded frame is adopted, the drawing mandrel is suspended above the frame, guide rails are installed on the frame, and two composite master cylinders are installed. The beam is connected, and the moving beam is equipped with multiple ring dies and multiple sets of roller dies, and the moving beam moves up and down along the guide rail to realize the drawing and stretching action. This kind of vertical drawing press has good rigidity and relatively compact structure, but it can...
