Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 5, the punching mechanism 1 may include a support 11, a slide rail 12, a slider 13, a punching die 14, a core rod 15, a punch 16, a punch cylinder 17, a material returning rod 18, and a material returning cylinder 19. Wherein, the support 11 is fixed on a workbench (not shown), a striker plate 111 is fixed on a side surface thereof, and the striker plate 111 has a certain inclination angle, for example, about 60 degrees, so that the outer sleeve 100 (as shown in fig. 5) after punching can fall onto a discharge hopper (not shown) below the same. A slide rail 12 is mounted on the top end of the support, the slide 13 being slidingly engaged on said slide rail 12. The punching die 14 is fixed on the slide block 13 and has a cavity 140, and one end of the cavity 141 is open and the other end is closed. The cavity 141 is opened toward an automatic feeding mechanism (not shown). The opening of the cavity 141 is flared, i.e. the opening is large outside and small inside, like a trumpet, so as to facilitate the insertion of the outer sleeve 100 into the cavity 141. The core rod 15 is coaxially fixed in the cavity 141. The diameter of core rod 15 is slightly smaller than the inner diameter of outer sleeve 100. The end 151 of the core rod 15 at the opening of the core rod 15 is conical to provide a guide for the outer sleeve 100 to fit over. The core rod 15 prevents the outer sleeve 100 from being deformed during the punching process.

Three punches 16 are mounted above the cavity 141 in driving connection with the punch cylinder 17 to punch 3 through holes 101 simultaneously. Specifically, three punches 16 are fixed to the punch holder 161, the punch cylinder 17 is fixed to the cylinder holder 171 and the telescopic rod thereof is connected to the punch holder 161 through the cylinder holder 171. The cylinder mount 171 is mounted on the punch 14 by four guide posts 172. Punch holders 161 are secured to guide posts 172 by respective linear bearings. Accordingly, the punch holder 161 can move up and down by the punch cylinder 17. One end of the stripper bar 18 is fixed and the other end is movably disposed through the closed end of the punch 14 and opens into the cavity 140. The telescopic rod of the material returning cylinder 19 is connected to the punching die 14. During material returning, the material returning cylinder 19 drives the punching die 14 to move towards the direction far away from the feeding direction, and the material returning rod 18 ejects the outer sleeve 100 out of the cavity 140 and falls into the material discharging hopper along the material blocking plate 111.

The punching die 14 may include an upper die 141 and a lower die 142. The upper die 141 has a downwardly protruding strip portion 1411, and a lower end surface of the strip portion 141 is circular arc-shaped. The lower die 142 is provided with a U-shaped groove, the bottom of the U-shaped groove is provided with a plurality of supporting blocks 1421 protruding upwards, and the upper end surfaces of the supporting blocks 1421 are arc-shaped. When installed, the strip portion 1411 is received in the U-shaped channel and the cavity 140 is formed between the strip portion 1411 and the support block 1421.

The closed end of the cavity 140 of the punching die 14 is provided with a buffer limiting assembly 110, so that the outer sleeve 100 is buffered and limited during the process that the outer sleeve 100 is pushed into the cavity 140 by the pipe pushing mechanism 5. Specifically, the bump stop assembly 110 includes a top block 1101, a spring 1102, a spring mandrel 1103, a mounting seat 1104, a second sliding rail 1105 and a second sliding block 1106, wherein the second sliding rail 1105 and the mounting seat 1104 are fixed on the punching die 14 (specifically, the lower die 142). A second slider 1106 is slidably engaged on the second sliding track 1105. The top block 1101 is fixed to the second slider 1106 by a connecting block 1107. The lower end of the top block 1101 abuts the core rod 15. The spring mandrel 1103 is movably secured to the mounting base 1104 through the top block 1101. The spring 1102 is fitted over a spring mandrel 1103 between the top block 1101 and the mounting base 1104.

In punching, the auto feed mechanism inserts the outer sleeve 100 into the cavity 140 until it abuts the top block 1101 and the spring 1102 is compressed. The outer sleeve 100 is now sandwiched between the top block 1101 and the automatic feed mechanism under the action of the spring 1102. And the punch cylinder 17 acts to drive the punch 16 to move downwards to complete punching. Then the material returning cylinder 19 is operated (the telescopic rod is retracted), the material returning rod 18 ejects the outer sleeve 100 out of the cavity 140 and falls into the material discharging hopper along the material stopping plate 111, after the material returning operation is completed, the material returning cylinder 19 is reset (the telescopic rod is extended), so that the punching die 14 returns to the initial position to perform the next punching operation.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
