Abstract

The utility model relates to a punching device for a punching machine. The punching device comprises a cutter and a base and is characterized in that the base is provided with a central hole, a first fastening piece is connected with the cutter through the central hole, meanwhile, the base is provided with an arc hole taking the central hole as the center of a circle, and a second fastening piece passes through the arc hole to be connected with the cutter. The base of the punching device for the punching machine is additionally provided with the arc hole taking the central hole as the center of a circle, thus the cutter can rotate around the first fastening piece along the arc hole to a required angle and then is located by aiming to the requirements of different angles on ends of products during punching so that the products at any angles can be punched. After the punching device for the punching machine, disclosed by the utility model, is utilized, the cutter cannot be changed and only the angle of the cutter relative to the base needs to be regulated when the punching products are changed; and the cutter is arranged on the base and does not need to be arranged and managed in a single place, therefore, the production management is remarkably convenient, and the punching device has the characteristics of high production efficiency and low cost.

Description

A kind of blanking units that is used on the bicker

Technical field

The utility model relates to a kind of blanking units, specifically refers to a kind of blanking units that is used on the bicker.

Background technology

All dispose the long and narrow panel of various sealings and decoration function in the existing automobile, the panel body adopts resin materials such as polyvinyl chloride or polyolefin to make mostly.For the shape with positions such as car door, vehicle window or roofs matches, each panel all will be as required die-cut end earlier, and then be fused into required form mutually.

When die-cut above-mentioned panel end, generally adopt bicker, cutting knife is fixed on the pedestal.Because the welding angle difference of each product, therefore, when the angle of die-cut product end, each product all has corresponding with it cutting knife.Therefore adopt present bicker, though also can realize die-cut purpose, exist following defective: (1) cutter is of a great variety, needs special place of placing, and needs often maintenance, and is difficult to management, loses phenomenon easily.(2) fix owing to the cutting knife mounting means, for the cutting knife of different angles, because of different, so repair very inconvenient.(3) change product when die-cut at every turn, all will seek corresponding cutting knife, install and the counterdie tool setting, inconvenient operation promptly has the cutting knife of changing frequency height, Installation and Debugging difficulty, the drawback that production efficiency is low.

The utility model content

Technical problem to be solved in the utility model is at above-mentioned prior art present situation, provides a kind of and need not to change that cutting knife just can die-cut product at any angle is used for blanking units on the bicker.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this blanking units that is used on the bicker comprises cutting knife and pedestal, it is characterized in that: have centre bore on the described pedestal, first securing member links to each other with described cutting knife after passing this centre bore, having on described pedestal with described centre bore simultaneously is the arcuate socket in the center of circle, and second securing member links to each other with described cutting knife after passing this arcuate socket.

As further improvement of the utility model, described cutting knife is positioned on the cutting knife fixed head, described first securing member passes and fixes with this cutting knife fixed head behind the described centre bore and realize linking to each other with described cutting knife, second securing member passes and fixes with this cutting knife fixed head behind the described arcuate socket and realize linking to each other with described cutting knife, by means of the cutting knife fixed head, the adjustment angle that had both helped cutting knife also helps the replacing operation of cutting knife simultaneously.

In above-mentioned each scheme, described first securing member can be bolt, accordingly, has screw on described cutting knife fixed head.Same described second securing member can be bolt, accordingly, has screw on described cutting knife fixed head.Can certainly adopt other to make both all-in-one-piece fastening structures that is fastened.

Described arcuate socket preferably has two, and is positioned on the same radius, can enlarge cutting knife angle adjustment scope like this, also can not weaken the intensity of pedestal simultaneously because of excessive arcuate socket.

Described cutting knife is to be designed to square body, and blade is positioned on the lower edge of this square body, keeps in repair and install all very convenient like this.

Compared with prior art, because having set up with the centre bore in the pedestal of the present utility model is the arcuate socket in the center of circle, therefore when die-cut, demand at product end different angles, cutting knife after turning to required angle along arcuate socket, first securing member is located, to realize die-cut product at any angle.After promptly adopting the utility model, when the replacing product is die-cut, can't change cutting knife, as long as adjust the angle of cutting knife with respect to pedestal, and because cutting knife is installed on the pedestal, does not need to be provided with independent place and place, manage, therefore made things convenient for production management significantly, and also has the production efficiency height, the characteristics that cost is low.

Description of drawings

Fig. 1 is the perspective view of the utility model embodiment;

Fig. 2 is the three-dimensional exploded view of Fig. 1.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, this blanking units is applied on the manual bicker, it comprises pedestal 1, cutting knife 2 and cutting knife fixed head 3, wherein have centre bore 11 on the leading section of pedestal 1 and be two arcuate sockets 12 in the center of circle with this centre bore, in the present embodiment, two arcuate sockets 12 are positioned at the left and right side of centre bore 11, and one-tenth is symmetrical arranged; The rearward end of pedestal 1 has two slotted hole 13 is installed, and is used for fixing on cylinder, by the action of cylinder, drives pedestal and moves up and down.

Above-mentioned cutting knife 2 is designed to thin square body, blade is positioned on the lower edge of this square body, the top of cutting knife 2 is fixed on the cutting knife fixed head 3 by two set bolts 6, in the present embodiment, cutting knife fixed head 3 is designed to L shaped structure, and cutting knife 2 is fitted on the vertical edge of this cutting knife fixed head 3, and the vertical edge of this cutting knife fixed head has two screws 31, said fixing bolt 6 passes the cutting knife rear thread and is connected in this two screw 31, so that cutting knife 2 is securely fixed on the cutting knife fixed head 3.

The horizontal edge of above-mentioned cutting knife fixed head 3 is attached on the bottom surface of said base 1 leading section, horizontal edge at this cutting knife fixed head 3 has relative with centre bore, the arcuate socket of pedestal respectively first screw 32, second screw 33, first bolt 4 passes these centre bore 11 rear threads and is connected in first screw 32, and second bolt 5 passes arcuate socket 12 rear threads and is connected in second screw 33.

When need adjusting die-cut angle, unclamp first bolt and second bolt, then cutting knife is forwarded to the angle that needs, and then tighten first bolt and second bolt gets final product.
