Abstract

The present invention provides a multi-stroke forming machine, which is mainly composed of a cut-off device, a female die device, a clamping device, a back punching device, a male die device, and a front punching device, all configured on the machine platform. Oblique tangent surfaces are formed on the two side faces opposing to the notch on the clamping part of the clamping device for guiding the front punching rod of the male mold device. When the front punching rod is not aligned with the positions of clamping device and the die cavity of the female die device, the front punching rod will impact the oblique tangent surface of the clamping part, and the clamping device will shake. The operator can immediately find the center misalignment and carry out adjustment so as to prevent the front punching rod and clamping device from deformation and damage. When the clamping device is clamping the blank, which is extremely stable, it can quickly move the blank to the next female die device for stamping operation. By the action of the front punching device, the blank on the front punching rod of the male die device can be favorably punched out, and rapid forming of fasteners by multi-stamping operation can be accomplished through in line production.

Description of the Invention: [Technical Field] [0001] The present invention relates to a multi-stroke molding machine, in particular to cutting a metal wire into a billet and holding the billet by a clamping device One—transfer to the master mold device for stamping, which can reach the consistent operation of multiple stamping and rapid forming fasteners. [Prior Art] [0002] According to the general forged article (such as a fastening member), the rolled metal wire is mainly sent to the molding machine, and the metal wire is cut into a blank through a cutting device: a cutting device. Then, the blank is clamped to the female mold base corresponding to the male mold base via the clamping device, and the blank material is sequentially stamped to the molds of each female mold through two front punch rods on the male mold base of the punching and forging mechanism. Forming in the cavity, and the back punching bar is arranged in the cavity of the female die, and the limb material which is punched and located in the cavity is pushed outward, and is clamped by the clamping device, and then clamped by the holding device Driven to move the blank to the position of the next master mold, the gentleman's number of front punches are repeatedly stamped and forged, and to prevent _ from the front punch from the mold cavity, so the front punch The upper venting mechanism is provided with a front opening and closing mechanism [0003] 098126899. Before the line is formed, please refer to the first and second figures. Mainly, the punching mechanism m is provided with a male mold mechanism ig and a sliding mechanism ^ η The mechanism 10 corresponds to the male mold mechanism (not shown), and the male mold mechanism 1G includes - is hollow and After being slip-mounted, the front punch 101 is installed in the space 100, the first pass-out guard is opened, the women's wear is on the back side of the punch rod 101, and the front door is installed in the front punch bar 101. The second pass lock 1〇3 on the front side of the outlet pin 102, the first pass = the form number A0101 page 4 / a total of 43 page 0982 (201105434

The base portion 102 has a push portion 104 which is radially enlarged and hollow. The end of the second pass pin 103 extends into the space formed by the push portion 104, and the push portion 104 can push the front punch rod 101. At the end, a sliding mechanism 11 is disposed behind the male mold mechanism 10. The sliding mechanism 11 includes a sliding body 110. The sliding body 110 is provided with a plurality of axles 111, and a plurality of axles 111 mounted on the sliding body 110. a front main pole 112, and a plurality of power units 12 for driving the front main pole 112 to move forward, the power unit 12 includes a plurality of rocker arms 120 that are pivotable forward and backward, and a plurality of driving units The power source 121 of the rocker arm 120 includes a cylinder 122, a cylinder shaft 123 and a linkage 124. The upper end of the linkage 124 is provided with a linkage plate 125, and the linkage plate 125 is fastened. Connected to the bottom edge of the rear side of each rocker arm 120, such that when the male mold device 10 is in the non-outward position, the bottom section of the rocker arm 120 is in a rearward position, and the front main pole 112 is located on the axle 111. Medium and in contact with the first outgoing pin 102 of the front end, when the outgoing action is to be performed, by power When the operation of 121, the cylinder shaft 123 is moved into the cylinder 122, the cylinder shaft 123 drives the linkage 124 to move forward, and the linkage plate 125 at the upper end of the linkage 124 is rotated forwardly against the lower end of the rocker arm 120, the rocker arm 120 rotates forward and pushes forward the front main pole 112 forwards, the front main rod 112 and pushes the first outgoing pin 102 forward, and the first outgoing pin 102 pushes forward the forward stick 101 forwards, so that The front punching rod 101 protrudes more than the second through-out pin 103 to form an open-out state (as shown in the second figure).
