Abstract

The utility model relates to a blanking die of a scraping plate. An upper die part and a lower die part are connected by a guide sleeve and a guide post; and in the upper die part, an upper die block is installed on an upper die plate by an upper fixing plate and an upper shim plate, a die shank is installed on the upper die plate, and oblique cutting edges which are mutually vertical are arranged on the upper die block. In the lower die part, a lower die block is installed on a lower die holder by a lower shim plate and a fixing plate of a lower die, and a material pressing plate is also installed on the fixing plate of the lower die. Under the condition of ensuring that the processing size of the scraping plate conforms to the design requirement, the blanking die of the scraping plate, which is provided by the utility model, can enhance the production efficiency of labor greatly, saves the consumption of the production cost and shortens the production period. The upper die block adopts the oblique cutting edges, so that the blanking clearance of the upper die part and the lower die part can be decreased, and the blanking face of a component is comparatively smooth. The utility model can lower the blanking force and decreases the vibratility when a thick plate is blanked, so that the blanking process is steady, and the quality and the production safety of the scraping plate are ensured.

Description

The scraper plate blanking die

Technical field

The utility model relates to and buries the scraper plate manufacture field, particularly a kind of scraper plate blanking die that does not have machining.

Background technology

The machine kernel component of burying is a flight chain, and the quantity of this part is many, big in batches, and the process-cycle is longer.Its middle scraper quantity is the twice of chain bar, promptly on a flight chain two scraper plates is arranged.The existing scraper plate mode of production is to adopt Milling Process, because the specifications and models of scraper plate are many, every kind of specification quantity is big, and its production efficiency far can not adapt to the demand in market, and production cost is higher.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of scraper plate blanking die, can improve the efficient of burying machine scraper processing, cuts down finished cost.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of scraper plate blanking die, and the part of the upper die is connected with guide pillar by guide pin bushing with the part of the lower die;

In the described part of the upper die, upper module is installed on the cope match-plate pattern by upper mounted plate and upper padding plate, and die shank is installed on the cope match-plate pattern, and upper module is provided with mutually vertical oblique cutting edge.

In the described part of the lower die, lower module is installed on the die shoe by lower bolster and counterdie fixed head, and holding pad also is installed on the counterdie fixed head.

Also be provided with dumping pit on the described die shoe.

Described lower module is two.

Cutting edge on the described lower module is two.

Described location-plate is provided with adjustment hole.

Mutually vertical oblique cutting edge on the described upper module is two.

A kind of scraper plate blanking die that the utility model provides can significantly improve labor productivity guaranteeing that the scraper plate processing dimension adheres to specification down, saves production cost, and shortens the production cycle.Upper module adopts mutually vertical oblique cutting edge, its blanking pressure than flat sword blanking pressure reduce near half, and the good stability of punching press.Mutually vertical oblique cutting edge on the upper module and the cutting edge on each lower module are two, and after the cutting edge wearing and tearing, the Rotate 180 degree can use another cutting edge to process like this.Location-plate is provided with adjustment hole, can pass through to regulate the position of location-plate, thereby adapt to the size that different scraper plate needs are processed.The holding pad that is provided with on it ejects in punching course to prevent blank.The dumping pit that a rectangle is arranged in the middle of the die shoe is in the trash receptacle of the waste material of stamping-out below dumping pit falls into workbench.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is the vertical view that removes the part of the upper die in the utility model.

Fig. 3 is through the blank schematic diagram after the processing.

The specific embodiment

In Fig. 1, a kind of scraper plate blanking die, the part of the upper die is connected with guide pillar 2 by guide pin bushing 1 with the part of the lower die; The relative position of upper module 10 and lower module 6 in the work, it is the blade clearance, guarantee the relative position of cope match-plate pattern 12 and die shoe 8 by the guide pin bushing 1 on guide pillar on the die shoe 2 and the cope match-plate pattern 12, also just guaranteed the relative position of upper and lower module, i.e. the blade clearance.

In the described part of the upper die, upper module 10 is installed on the cope match-plate pattern 12 by upper mounted plate 14 and upper padding plate 11, and mounting means connects for the hexagon socket head cap screw with M16.Die shank 13 is installed on the cope match-plate pattern 12, and upper module 10 is provided with mutually vertical oblique cutting edge.Adopt oblique cutting edge can reduce the blade clearance of upper and lower mould part, the stamping-out face of part is more smooth.Can reduce blanking pressure, the vibratility when reducing the slab stamping-out makes the stamping-out process steady, guarantees the quality of scraper plate and the safety of production.

In Fig. 2, in the described part of the lower die, lower module 6 is installed on the die shoe 8 by lower bolster 5 and counterdie fixed head 15, and holding pad 3 also is installed on the counterdie fixed head 4.

The dumping pit 7 that a rectangle is arranged in the middle of the die shoe 8 is in the trash receptacle of the waste material of stamping-out below dumping pit 7 falls into workbench.

The combining structure of inserting is adopted in the part of the lower die, can save expensive mold materials, and it is convenient to change after the module damage.Described lower module 6 is two.Described lower module cross section adopts rectangle, and the cutting edge on the lower module 6 is two.

Described location-plate 15 is provided with adjustment hole, and this adjustment hole is microscler hole slot, adopts adjustable location-plate structure, and the scraper plate that helps all size model commonly used can both position processing.

Mutually vertical oblique cutting edge on the described upper module 10 is two, and switch the back of being convenient to wear and tear.

Scraper plate blank 9 is placed on the lower module 6, with holding pad 3 sides blank 9 is carried out the directions X location, the size according to the processing of scraper plate needs positions fastening in the Y direction location-plate 15 again.The part of the upper die moves down down at press ram, upper module 10 is cut the front end of blank 9 earlier at the oblique cutting edge of Y direction, along with press ram continues to move down, the directions X oblique cutting edge is then cut the right-hand member of blank 9, until unnecessary material is cut away, whole process only needs a few times in second.At this moment the part of the upper die is along with the top shoe of forcing press upwards returns, thereby finishes whole process.
