Abstract

The invention discloses a puncher which comprises a quick replacing head (1), a head replacing clamping device (2), handles (3), a storage hole (4), a buffer block (5) and a quick replacing head cutting head (6). The puncher has a hole punching function and a pit punching function. Due to use of the puncher, on the one hand, the labor intensity of an operator is lowered, and a large amount of work time of workers is saved; on the other hand, the manufacturing quality of a product is improved during actual production.

Description

Piercer

Technical field

The invention belongs to multipurpose tool field, be specifically related to a kind of piercer.

Background technology

At the scene in actual production process, for rushing nest punching, the punching of a kind of aperture or the degree of depth or nest pair processedShould use a kind of instrument, and for the producing of hole, large aperture, the general mode that adopts the system of cutting. And collection punching withRush nest in the piercer of one, do not occur in the market.

In the on-the-spot actual production process of prior art, punching is all very loaded down with trivial details work, requires the degree of accuracyHeight and labour intensity are large, and modal method is exactly first true by drawing or other processes by operative employeeDetermine position, hole, then use hand hammer to beat old-fashioned punching tool, hole is formed. Meanwhile, for disposableBe shaped, also need to be below workpiece chock plate or other buffering instruments, sometimes also need operated by two people. This justGreatly increased human cost, punching qualification rate is not high yet.

Summary of the invention

The present invention has overcome the deficiencies in the prior art, has proposed a kind of multi-function instrument, fast by changingChange head, realize the punching of different pore size to floor protective rubber skin and the following aluminum hardware of 0.8mm and rush nest etc. manyPlant function, reduced the use amount of instrument, promote operating efficiency, improved product quality.

Consider the problems referred to above of prior art, according to an aspect disclosed by the invention, the present invention adopt withLower technical scheme:

Piercer, comprise quick change head (1), change a clamping device (2), handle (3), storing hole (4),Buffer stopper (5), quick change head crop (6), piercer front end is provided with removable quick change head (1), fastChange head (1) bottom for quick change head crop (6), storing hole (4) are arranged at piercer front end quick change head (1)The back side, piercer front end is also provided with and changes a clamping device (2), after quick change head (1) packs into by changing headClamping device (2) compresses quick change head (1), on the piercer front end another side corresponding with quick change head (1)Buffer stopper (5) is set, and piercer also has handle (3), and handle (3) is also established by piercer front end one sideBe equipped with spring.

Described piercer has punching function, and in the time of punching, quick change head (1) adopts formpiston, buffer stopper (5)Adopt former, quick change head (1) cuts off material completely by punching, realizes punching.

Described piercer also has the nest of punching function, and in the time rushing nest, quick change head (1) adopts formpiston, buffer stopper (5)Adopt former, quick change head (1) is washed into the immerse oneself in nest identical with countersunk rivet tapering by punching by material, realNow rush nest.

It is that T8 steel processes that described quick change head (1) adopts material.

Described buffer stopper (5), material is copper.

In the process of use piercer, every hundred circulating times were reduced to 1 hour by 4 hours, institute's punching circleDegree precision improves greatly. The use of this piercer, has reduced operator's labour intensity on the one hand, saves workThe working time that people is a large amount of, on the other hand, the workmanship of improving product in actual production.

Detailed description of the invention

Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limitIn this.

Referring to accompanying drawing 1-3, piercer, comprise quick change head (1), change a clamping device (2), handle (3),Storing hole (4), buffer stopper (5), quick change head crop (6), piercer front end is provided with removable fastChange head (1), quick change head (1) bottom is quick change head crop (6), and storing hole (4) are arranged at piercerThe back side of front end quick change head (1), piercer front end is also provided with and changes a clamping device (2), in quick change head (1)After packing into, compress quick change head (1) by changing a clamping device (2), right at piercer front end and quick change head (1)Buffer stopper (5) is set on the another side of answering, and piercer also has handle (3), and handle (3) is by piercerFront end one side is also provided with spring.

Use the step of this instrument to be:

1, determine Kong Weiyu pore size by drawing and process;

2, required quick change head is installed on piercer;

3, the operation tool of pressing need of production, in the handle place application of force, makes drift real to workpiece by shearing mechanismExecute punching or rush work holdup order;

4, when punching, when storing hole load to a certain extent after, it is cleared up.

Piercer of the present invention is made simple, and tool carrier and combination pliers are basic identical, and difference isFront end has increased quick change head and has carried out implementation. In order to increase serviceability and the durability of product, quick change head instituteThe material adopting is that T8 steel processes, and has so both increased the sharpness of crop, has increased again productService life. Designed the buffer stopper of simultaneously working with quick change head, material is copper simultaneously. Like this can be betterMake crop work can protect part injury-free. And in the time that needs rush nest, quick change is changed to sun first watchMould buffer stopper is replaced by former and can completes and rush work holdup order.

The handle design of this product has rubber protecting jacket, has improved the comfortableness using also anti-skidding, in order to avoid makeWith the part of hurting sb.'s feelings during due to undue force in process. Front end quick change head is provided with and changes a clamping device, has improved peaceWhen full property, manufacture accuracy and tool stability are also improved. Simultaneously this product design spring mechanism,More laborsaving when use.

And the present invention only need determine position, hole and pore size in accordance with regulations, the single executable operations operation that gets final product.

And quick change head be designed with two kinds of former, formpistons. Former can be used for punching, and formpiston can be used forRush nest for the aluminum hardware that is less than 0.8mm, size and precision can need to be adjusted according to scene, chooseSuitable drift is to meet the demands.
