Technical Field

The utility model belongs to the technical field of the technique of lath punching press and specifically relates to a mould for punch press is related to.

Background

In the production and manufacturing process of the plate rib, stamping is needed according to requirements to form a hole or a specific shape. The stamping process is often performed in a press.

Chinese patent with publication number CN 207872841U discloses a punch, the technical scheme is that the punching machine comprises a frame, the workstation of setting in the frame, the slider of setting in the workstation top, set up two drifts in the slider below and set up the drive mechanism who drives the slider and carry out the motion on the workstation, still including setting up the fixture on the workstation, fixture is including setting up the supporting seat on the workstation, the setting is the grip block on the supporting seat, set up in supporting seat top both sides and pass the reference column of grip block and the spring of cover on the reference column, set up the semicircle form that is that the grip block below sets up and connect matched with draw-in groove with the drum on the supporting seat, draw-in groove one end is seted up and is half the constant head tank of plate joint with plate joint matched with thickness, set up the corresponding round hole that runs through the supporting seat.

The above prior art solutions have the following drawbacks: in actual processing, the plate ribs are often rectangular panels. When the plate ribs are punched, an operator needs to hold the plate ribs by hand and correct the positions of the plate ribs, and then the punch is started to enable the punch to punch the plate ribs. However, when the operator determines the position of the plate rib, the deviation occurs, which causes an error in the size of the punched product.

Disclosure of Invention

The utility model aims at providing a mould for punch press has the advantage of carrying out the position to the plate reinforcement and injecing.

The above object of the present invention is achieved by the following technical solutions:

a die for a punch comprises a working table plate, wherein first limiting rods are fixed on the working table plate, at least two first limiting rods are arranged at intervals, and all the first limiting rods are positioned on the same straight line; the limiting block is further fixed on the working table plate, one side of the limiting block, facing the first limiting rods, is perpendicular to the working table plate, and the side of the limiting block is perpendicular to straight lines where all the first limiting rods are located.

Through adopting above-mentioned technical scheme, in the actual operation process, the slab muscle that will need the punching press is placed on the work platen for one side of slab muscle is supported tightly on the stopper lateral wall, and adjacent one side is supported tightly on first gag lever post, thereby has restricted to be the adjacent both sides of rectangular slab muscle, thereby has injectd the position of slab muscle. Then, the plate rib is stamped, so that the precision of a stamped product is improved, and the working efficiency can also be improved; the operator only needs to support the two sides of the plate rib tightly on the limiting block and the first limiting rod respectively, and the operation is convenient and fast.

The utility model discloses further set up to: the working table plate is provided with a fixing groove, and the opening direction of the fixing groove is perpendicular to the straight line where all the first limiting rods are located; the limiting block is in sliding fit along the opening direction of the fixing groove, and a locking assembly used for locking the position of the limiting block is additionally arranged between the limiting block and the fixing groove.

Through adopting above-mentioned technical scheme, adjust the position of stopper in the fixed slot according to the lath of different width. When the slab muscle width is less, remove the stopper and be close to first gag lever post for the middle part of the minor face of slab muscle can support tightly with the lateral wall of stopper, thereby improves spacing effect, and the operating personnel of being convenient for can confirm the position of slab muscle fast.

The utility model discloses further set up to: the limiting block comprises a touch plate and a connecting plate which are perpendicular to each other; one side of the abutting plate abuts against the side wall of the fixing groove, and the connecting plate is arranged in parallel to the working table plate; the locking assembly comprises a threaded rod arranged on the connecting plate in a penetrating mode and a nut in threaded fit with the threaded rod, and a sliding block is fixed at the bottom of the threaded rod; the working table plate is provided with a sliding groove parallel to the fixed groove, and the sliding block is embedded in the sliding groove and is in sliding fit along the sliding groove; when the position of the connecting plate is locked, the nut is tightly propped against the upper surface of the working table plate.
