Description

Technical Field

[0001] The invention relates to the field of seamless pipe profile preparation, and in particular to a material ejecting device for a punching machine. Background Art

[0002] The perforator is a new type of high-quality equipment used to prepare seamless pipe profiles. It can prepare holes quickly, efficiently and with high precision, so that the profiles can be processed into seamless pipes.

[0003] During processing, the waste material after punching will be blocked in the punching needle, resulting in precision errors in the next punching. After the profile is fixed for processing, the expansion of the profile will cause "adhesion" between the profile and the processing equipment, making it impossible to quickly remove the processed profile from the equipment, affecting the processing efficiency and the stability of the gripping equipment. Summary of the invention

[0006] Furthermore, the pushing assembly includes a pushing rod and an auxiliary power plate, the auxiliary power plate is arranged between the perforating platform and the two-stroke power cylinder, and a first abutment portion is arranged on the telescopic rod of the two-stroke power cylinder. When the second stroke of the two-stroke power cylinder is actuated, the first abutment portion pushes the auxiliary power plate to move.

[0007] Furthermore, a push plate is provided on the bottom of the positioning groove, and the push plate is connected to the push rod.

[0008] Furthermore, an elastic reset component is provided between the push rod and the perforation platform.

[0009] Furthermore, a second abutment portion is provided on the telescopic rod of the double-stroke power cylinder between the perforating platform and the auxiliary power plate.

[0011] Furthermore, the double-stroke power cylinder is a double-extension structure, and a stroke limit nut is provided on one of the extension ends.

[0012] Beneficial effects of the present invention:

[0013] Through the setting of the double-stroke power cylinder, the ejector head and the pusher assembly can move separately to push the waste into the piercing needle and separate the profile from the equipment, thereby improving the processing accuracy, and the grabbing equipment can easily and quickly grab the processed profile.

[0018] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0019] Reference Figure 1 and Figure 2 As shown, an embodiment of the material ejection device for a punching machine of the present invention comprises a punching platform 1, a positioning groove 2 is arranged on one side of the punching platform, a double-stroke power cylinder 3 is arranged on the other side of the punching platform, a material ejection head 4 is arranged on the punching platform in the positioning groove, the material ejection head extends into the positioning groove through the first stroke of the double-stroke power cylinder, and a material pusher assembly 5 is also arranged on the punching platform around the material ejection head, and the material pusher assembly extends into the positioning groove through the second stroke of the double-stroke power cylinder. When in use, one end of the profile is arranged in the positioning groove for positioning, and when the punching is completed, the double-stroke power cylinder first moves the first stroke, and in the first stroke, the material ejection head is driven to move by the double-stroke power cylinder, so that the waste in the punching needle can be completely pushed into the inside of the punching needle, and there is no waste material blocking the next punching, which effectively improves the accuracy; after the punching is completed, the punching needle resets and exits the profile, and then the profile needs to be grabbed, at this time, the double-stroke power cylinder first moves the second stroke, and the double-stroke power cylinder drives the material pusher assembly to push the profile out of the positioning groove, thereby completing the "separation" effect. The double stroke effect can ensure that when the ejector head is working, the pusher assembly does not move first, and the two do not interfere with each other when completing their respective actions, and the operation is stable and reliable.

[0020] The above-mentioned pusher assembly includes a pusher rod 6 and an auxiliary power plate 7. The auxiliary power plate is arranged between the perforation platform and the double-stroke power cylinder. The telescopic rod of the double-stroke power cylinder is provided with a first abutment portion 31. When the second stroke of the double-stroke power cylinder is actuated, the first abutment portion pushes the auxiliary power plate to move. The movement of the auxiliary power plate can drive the pusher rod to move, that is, push the profile into the positioning groove. A receiving hole for the pusher rod is provided on the perforation platform, and a guide sleeve can also be provided in the receiving hole to ensure the stability of movement.

[0021] A push plate 8 is also provided at the bottom of the positioning groove, and the push plate is connected to the push rod. When the push rod is pushed out, it can drive the push plate to move and push the profile out. The push plate abuts against the profile to increase the contact area with the profile, avoiding quality problems such as pits caused by the rod-like structure squeezing the end face of the profile.

[0022] In order to provide operational stability, an elastic reset component is provided between the push rod and the perforation platform. When the double-stroke power cylinder is reset, the pushing force of the auxiliary power plate disappears, and the elastic reset component resets the push rod through elastic force, thereby achieving the effect of retracting the push plate.

[0023] The above-mentioned double-stroke power cylinder is set as a double-extension structure, and a stroke limit nut 9 is provided on one of the extension ends. When the double-stroke power cylinder is extended to push out the profile, the large impact force will cause the piston inside the double-stroke power cylinder to collide with the inner end and cause damage. Therefore, the stroke limit nut can offset the impact force on the outside, thereby achieving the effect of improving service life and stability.

[0024] In one embodiment, referring to Figure 3 As shown, a positioning ring 10 is arranged in the positioning groove, and one side of the inner ring wall of the positioning ring is arranged as a conical ring surface 11. When the profile enters, the inclined portion of the conical ring surface has a good guiding effect, which can assist the profile to move into the positioning without causing the problem of material jamming.

[0025] In one embodiment, referring to Figure 4 As shown, a second abutment portion 12 is also provided on the telescopic rod of the double-stroke power cylinder between the perforating platform and the auxiliary power plate. When the first stroke of the double-stroke power cylinder is reset, the second abutment portion can abut against the surface of the auxiliary power plate and drive the auxiliary power plate to move, thereby achieving a reset effect.

[0026] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
