Abstract
The invention discloses a needle plate, comprising a rectangular plate body. The plate body is provided with a plurality of needle holes, at least two location holes and at least one fixed hole. The needle holes are arranged in two parallel rows; the two rows of the needle holes are arranged staggeredly; each needle hole is formed by two coaxial through holes with the lower through hole larger than the upper through hole; the left side of the plate body is provided with a butt-joint step cooperating with a former needle plate; the right side of the plate body is provided with a butt-joint step cooperating with a later needle plate. The needle plate is advantageous in that the two adjacent needle plates are connected by using a butt-joint step manner, so that distance between needle holes when the two needle plates butt can be guaranteed; and safety distance of the needle holes from the edge of the needle plate can be guaranteed. At the same time by employing the needle holes with the lower through holes larger than the upper through holes, automatic fall of waste cut during a work process is facilitated without blocking the needle holes.
Description
Technical field
The present invention relates to a kind of mould, specifically, relate to a kind of needle plate.
Background technology
The cushion that adopts leatherware as automobile cushion etc., all need to be pricked very many pores on leatherware, and these pores require size shape consistent and arrange in order, and no person can have influence on the aesthetic property of leatherware integral body.When pricking pore to these leatherwares, need to use the needle plate mould, some pin holes that arrange are according to certain rules arranged on needle plate, according to actual needs, some needle plates is in one line and have good positioning, leatherware is placed on needle plate, then because the suitable pin of pin hole presses down, mo(u)ld venting on leatherware.If but the pitch-row on needle plate is less, when the splicing of two needle plates, just can't guarantee with between the first pin hole of last pin hole of first block of plate of row and second block of plate apart between pin hole adjacent with other apart from equating, because pin hole and the panel edges of needle plate head end and art end also will maintain a certain distance, to guarantee the intensity of monoblock needle plate, and the pin hole of existing needle plate is because adopt straight through hole, be easy to be dropped on leatherware useless cut stop up cause the pin fracture or needle plate impaired, make a whole set of needle plate mould again to change, had a strong impact on production efficiency, increased the cost input.
Summary of the invention
The object of the present invention is to provide a kind of needle plate, can effectively solve existing needle plate in pitch-row hour, the pitch-row between two needle plates can't guarantee, simultaneously the easy blocked problem of pin hole.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of needle plate, the plate body that comprises rectangle, described plate body is provided with some pin holes, also be provided with at least two pilot holes and at least one fixed orifices on described plate body, described pin hole is set to two parallel rows, described two row's pin holes are crisscross arranged, described each pin hole forms by lower large two little coaxial through-holes, the left side of described plate body has the docking step coordinated with last needle plate, and the right of described plate body has the docking step coordinated with a rear needle plate.
Preferably, described two row's pin holes are symmetrical arranged about the plate body horizontal center line; When work, make whole needle plate stressed evenly, avoid causing the needle plate fracture because of unbalance stress.
Preferably, described pilot hole is two, and described two pilot holes arrange about the plate body centrosymmetry; More accurately needle plate is located.
Preferably, described fixed orifices is four, and described four fixed orificess lay respectively on four jiaos of plate body.
Preferably, described needle plate length is 70～74mm, and described needle plate is wide is 45～55mm, needle plate savoury 4～6mm, the through hole that described pilot hole diameter is 3～5mm, the threaded hole that described fixed orifices is diameter 3～5mm.
Preferably, described needle plate is long is 72mm, and needle plate is wide is 50mm, and needle plate is thick is 5.3mm, and described pilot hole diameter is 4mm, and described fixed orifices diameter is 4mm.
Preferably, described pin hole top is the dark 1.5～2.5mm of diameter 1.1～1.4mm, and the underpunch diameter is 1.45～1.6mm, with the adjacent pin hole width between centers of row, is 4～6mm, and the spacing between described two row's pin holes is 2～3mm.
Preferably, described pin hole upper diameter is 1.3mm, and the diameter of underpunch is 1.5mm, with the adjacent pin hole width between centers of row, is 5mm, and the distance between described two row's pin holes is 2.5mm.
Compared with prior art, advantage of the present invention is: adopt docking step mode to connect the connection between two needle plates, the spacing of pin hole while both having guaranteed two needle plate docking, guaranteed again the safe distance of pin hole from the needle plate edge, adopt lower large little pin hole simultaneously, facilitate useless in working process to cut automatic whereabouts, can not stop up pin hole.
