Abstract

The utility model discloses a keel hook punching machine. Four guiding rods are arranged between base of the hook punching machine and upper fixing plate. An Upper and a lower slide board cover are sleeved at the guiding rod. The upper template and lower template of mould are respectively fixed at the upper and lower slide board. The feed-in cylinder and the slide seat of the straight line guiding wheel are respectively provided with a pressing cylinder. The feed-in cylinder and the slide seat of the straight line guiding wheel are connected with each other by the connecting rod. The two sides of the left end of the discharging frame are respectively provided with a guide part which consists of a plurality of the rolling axis, only the single side of the right end of which is provided with the rolling axis to be supported. The mould has a guide pole, so as to ensure positioning precision of the connecting hook. The utility model overcomes the shortages of the prior art, and can manufacture the eligible part with convenient using and maintaining.

Description

The keel punching machine

The utility model relates to a kind of keel punching machine for building.

The DIPY construction formwork mesh technology is the new construction material from external introduction, the production of its part parts does not also have special equipment in China, prior art has two kinds: a kind of is to pass through the mould punching butt hook on general gap-framepress, the shortcoming of this technology is manual sending to, operational danger is big, and production efficiency is low.Another kind is the special equipment (Fig. 2) that Australia's design is produced, this equipment adopts hydraulic pressure towards hook, pneumatic sending to, the production efficiency height, simple to operate, but also there are many shortcomings in this equipment in design, mainly be that body 22 mechanisms are unreasonable, make more mold exchange 23 difficulties, more hydraulic cylinder 24 need be pulled down during mold exchange, and mould does not have the vertical direction guiding at work, and mould easily rotates in the horizontal direction.Send to and adopted the both sides cylinder, 21, one of propulsion cylinder pulls out that cylinder 26 is asynchronous to cause that to send step pitch to inaccurate, and two cylinders also are difficult to be transferred to synchronously.In addition, this machine is not equipped with blanking rack, and the keel of sending are offset, and has influenced the accuracy towards hook yet.

The purpose of this utility model is to design a kind of by sending the keel punching machine that main part such as cylinder, connecting rod, clamping cylinder, upper and lower sliding panel, guide post, base, rolling bearing, hydraulic cylinder, line slideway, blanking rack and mould is formed to for overcoming above-mentioned weak point.Improved product quality, and easy to use.

The utility model content: the keel punching machine comprises base, propulsion cylinder, clamping cylinder, hydraulic cylinder and mould, it is characterized in that: four guide posts are housed between base and upper mounted plate, and upper and lower sliding panel is sleeved on the guide post.The cope match-plate pattern of mould and lower slider plate are fixed, and the lower bolster of mould and lower slider plate are fixed.Respectively establish a clamping cylinder on the slide of sending cylinder and line slideway to, the slide of sending cylinder and line slideway to is rigidly connected with connecting rod.The both sides of blanking rack left end respectively are provided with the only one-sided supporting of being made up of several rolling bearings of establishing rolling bearing of correcting portion, blanking rack right-hand member.Mould is provided with the mould lead that keeps the butt hook positional precision.

The utility model advantage:

1. four guide posts are housed between base and upper mounted plate, constitute a closed frame, the upper and lower sliding panel that is sleeved on the guide post can upper and lower neatly reciprocating motion, has guaranteed the positional precision of mould.

2. send the sliding seat of cylinder and the sliding seat of line slideway to and be rigidly connected, guaranteed that two clamping cylinders are synchronized with the movement by connecting rod.

3. because mould is provided with mould correcting post, during work, this correcting post elder generation's contact workpiece and location, guarantee drift in the tram towards hook.

4. blanking rack of the present utility model front portion and correcting workpiece rear portion can make workpiece under the effect of deadweight, rollover is left blanking rack and is fallen into the car that connects material, so created stable condition of work in the hook process, keel can not be offset, and can not influence the accuracy towards hook yet.

Further prove the utility model below in conjunction with drawings and Examples.

(Fig. 3-Fig. 9) forms by sending cylinder 1, connecting rod 2, clamping cylinder 3, lower slider plate 4, guide post 5, base 6, upper sliding plate 7, upper mounted plate 8, hydraulic cylinder 9, line slideway 10, blanking rack 11, work piece 12, rolling bearing 13, mould correcting post 14, drift 15, cope match-plate pattern 16, holding pad 17, die 18, lower bolster 19 to the keel punching machine.

Base 6 connects into closed frame with upper mounted plate 8 by guide post 5 in Fig. 1, upper sliding plate 7 and lower slider plate 4 are under the effect of hydraulic cylinder, with guide post 5 is guiding, move up and down, the cope match-plate pattern 16 of mould (Fig. 5) is fixed on the upper sliding plate 7, lower bolster 19 is fixed on the lower slider plate 4, has guaranteed the positional precision of mould during towards hook.Two clamping cylinders 3 are separately fixed on the sliding seat of sending cylinder 1 and line slideway 10 to, send the sliding seat of cylinder and the sliding seat of line slideway to and are rigidly connected with connecting rod 2, guarantee that two clamping cylinders are synchronized with the movement.Fig. 4 is a blanking rack, left end (Fig. 8) in blanking rack is the correcting part, work piece 12 is when travelling forward, move on the rolling surface that rolling bearing 13 is formed in the bottom surface, Fig. 9 is the right-hand member of blanking rack, has only one-sided rolling to support, after work piece 12 is pushed out the correcting part, workpiece is under the effect of deadweight, and blanking rack is left in rollover, falls into the car that connects material.It towards hook the time positional precision that guarantees butt hook, and the error of elimination step pitch, mould (Fig. 5) is provided with mould correcting post 14, after beginning towards hook work, correcting post 14 first contact workpieces, and will be by towards part position levelling with the connection dog hole that has been washed into, with guarantee drift 15 in correct position towards hook.
