Description

Deviation-preventing punching machine for punching aluminum templates

Technical Field

The utility model relates to the technical field of aluminum template processing, in particular to an anti-deflection punching machine for punching an aluminum template.

Background

The aluminum template can be applied to the process of pouring concrete in the building industry, can demolish the aluminum template and recycle after the concrete solidifies the shaping, therefore obvious environmental protection benefit is used widely, aluminum template is in order to connect the equipment conveniently, need punch on the face, for high-efficient production, generally adopt the piercing press to punch, current piercing press during operation is first with the aluminum template insert between mould and the lower mould, then start the hydro-cylinder of piercing press, the hydro-cylinder promotes the slider and pushes down, and then drive the drift of mould down and punch a hole to the aluminum template, when the drift down in-process has not contacted the aluminum template yet, or before last mould and lower mould clamp aluminum template, aluminum template can outwards slide out, lead to punching position emergence skew, consequently influence the precision of punching processing.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provides an anti-deviation punching machine for punching an aluminum die plate.

The specific scheme of the utility model is as follows: a prevent partially punching machine for aluminum mould board punching a hole, including the board, the board upper end is equipped with the slider, the slider bottom is equipped with the mould, go up mould and slider fixed connection, go up mould below and be equipped with the lower mould, be equipped with the clearance that is used for inserting the aluminum mould board between mould and the lower mould, lower mould and board fixed connection, the front lower extreme of slider is equipped with a mounting groove, the mounting groove is arranged along the horizontal direction, be equipped with detachable bolt in the mounting groove, the bolt level outwards stretches out, bolted connection has the support, be equipped with on the support with bolted connection's lock nut, the support outside is equipped with the connecting rod that extends to the lower mould, a bracing piece that level was arranged is respectively equipped with to the connecting rod bottom both sides, bracing piece and slider parallel arrangement, the outside of two bracing pieces all is equipped with the rubber pinch roller in the cover, the rubber pinch roller is used for blockking the aluminum mould board.

Further, the section of the mounting groove is in a convex shape.

Further, the bracing piece rotates with the connecting rod to be connected, rubber pinch roller and bracing piece fixed connection.

The utility model has the following beneficial effects: through setting up the support, installation rubber pinch roller on the support for the in-process of punching a hole, the rubber pinch roller contacts the work piece earlier when the slider descends, plays the effect of blockking to the work piece, can avoid because the skew that the work piece deviates from the position leads to the hole like this when punching a hole, promotes machining precision.

In the figure: 1. a slide block; 2. a mounting groove; 3. a bracket; 4. a rubber pinch roller; 5. an upper die; 6. a lower die; 7. and (5) a bolt.

Detailed Description

Referring to fig. 1-3, the embodiment is an anti-deflection punching machine for punching an aluminum die plate, comprising a machine table, wherein a sliding block 1 is arranged at the upper end of the machine table, an upper die 5 is arranged at the bottom of the sliding block 1, the upper die 5 is fixedly connected with the sliding block 1, a lower die 6 is arranged below the upper die 5, a gap for inserting the aluminum die plate is arranged between the upper die 5 and the lower die 6, the lower die 6 is fixedly connected with the machine table, a mounting groove 2 is arranged at the front lower end of the sliding block 1, the mounting groove 2 is horizontally arranged, a detachable bolt 7 is arranged in the mounting groove 2, the bolt 7 horizontally extends outwards, a bracket 3 is connected with the bolt 7, a locking nut connected with the bolt 7 is arranged on the bracket 3, a connecting rod extending towards the lower die 6 is arranged at the outer side of the bracket 3, two support rods horizontally arranged at two sides of the bottom end of the connecting rod are respectively arranged in parallel with the sliding block 1, rubber pinch rollers 4 are sleeved outside the two support rods, and the rubber pinch rollers 4 are used for blocking the aluminum die plate. Further, the section of the installation groove 2 is in a convex shape. Further, the support rod is rotationally connected with the connecting rod, and the rubber pinch roller 4 is in interference fit with the support rod to realize fixed connection.

Through setting up rubber pinch roller 4 into the rotation and connect for be rolling friction between rubber pinch roller 4 and the work piece, thereby reduce the frictional force between rubber pinch roller 4 and the work piece, avoid extrudeing each other and lead to deformation damage. The working principle of the utility model is as follows: when the sliding block 1 is positioned above, the rubber pinch roller 4 is positioned above a gap of the aluminum inserting template, and at the moment, a worker can insert the aluminum template to be processed into the gap and then control the sliding block 1 to descend; when the sliding block 1 descends, the punch of the upper die 5 is driven to descend, before the punch contacts a workpiece, the rubber pinch roller 4 reaches a gap for inserting the aluminum template, the aluminum template is blocked, the workpiece is prevented from outwards shifting, and therefore the punching position of the punch is ensured to be accurate.

The utility model is provided with the mounting groove 2, thereby being convenient for mounting or dismounting the bracket 3, and the bracket 3 can be dismounted when other parts are processed without processing the aluminum template.
