Description

Technical Field

[0001] The invention relates to a material ejection device, in particular to a material ejection device on a cold forging press. Background Art

[0002] In the mold ejection device, rectangular springs are often used as elastic sources for ejection, but traditional rectangular springs have poor stability and are limited in the number of times they can be used.

[0003] Although using nitrogen springs to replace traditional springs can solve the above problems, the nitrogen springs on existing cold forging presses are generally installed inside just above the bottom surface of the slider. If the nitrogen spring is damaged, it is inconvenient to replace and repair it, and the maintenance cycle is long. Summary of the invention

[0004] The object of the present invention is to provide a material ejecting device for a cold forging press to solve the problems in the prior art.

[0005] The technical solution of the present invention is: a material ejection device on a cold forging press, the device comprising a mounting support, a nitrogen spring, a material ejection cross bar, a mounting plate, a slider, a guide sleeve, a material ejection shaft and a spring; The mounting support is fixedly connected to both sides of the slider, one end of the nitrogen spring is fixedly connected to the mounting support, the other end of the nitrogen spring abuts against the ejection cross bar, a mounting plate is arranged under the ejection cross bar to achieve positioning, the mounting plate is connected to the slider, a guide sleeve is arranged inside the slider, an ejection shaft is arranged inside the guide sleeve, and the ejection shaft is connected to the spring.

[0006] Furthermore, the guide sleeve and the ejector cross bar are in a vertical state.

[0007] The beneficial effects of the present invention are as follows: the nitrogen spring is installed outside the slider, and if the nitrogen spring is damaged, it can be replaced outside the slider without disassembling the mold, which is convenient for replacement, reduces the machine tool maintenance cycle, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural schematic diagram of the present invention.

[0009] Figure 2 yes Figure 1 Schematic diagram of the cross-sectional structure.

[0010] In the figure, 1 is the mounting support, 2 is the nitrogen spring, 3 is the ejector cross bar, 4 is the mounting plate, 5 is the slider, 6 is the guide sleeve, 7 is the ejector shaft, and 8 is the spring. DETAILED DESCRIPTION

[0011] A material ejection device on a cold forging press, the device comprising a mounting support 1, a nitrogen spring 2, a material ejection cross bar 3, a mounting plate 4, a slider 5, a guide sleeve 6, a material ejection shaft 7 and a spring 8; The mounting support 1 is fixedly connected to both sides of the slider 5, one end of the nitrogen spring 2 is fixedly connected to the mounting support 1, and the other end of the nitrogen spring 2 abuts against the ejection cross bar 3. A mounting plate 4 is arranged below the ejection cross bar 3 to achieve positioning, and the mounting plate 4 is connected to the slider 5. A guide sleeve 6 is arranged inside the slider 5, and an ejection shaft 7 is arranged inside the guide sleeve 6. The ejection shaft 7 is connected to the spring 8.

[0012] The guide sleeve 6 and the ejector cross bar 3 are in a vertical state.

[0013] The working process of the present invention is: when the mold part is forged, the part contacts the ejection shaft 7, the part supports the ejection shaft 7 and makes the ejection shaft 7 move upward, the ejection shaft 7 pushes the ejection cross bar 3 to move upward during the upward movement, and the ejection cross bar 3 presses the nitrogen spring 2; during the return stroke, the nitrogen spring 2 ejects the part in the mold cavity to realize the ejection function.

[0014] If the nitrogen bomb of this structure is damaged, it can be replaced outside the slide without disassembling the mold. The replacement is convenient, which reduces the maintenance cycle of the machine tool and improves production efficiency.

[0015] In the description of the present invention, it is necessary to understand that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] In the present invention, unless otherwise clearly stipulated and limited, for example, it can be a fixed connection, a detachable connection, or an integrated one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0017] The standard parts used in the present invention can all be purchased from the market, and the special-shaped parts can all be customized according to the description and the drawings.
