Description

The semiautomatic device proposed for protection for a utility model for bending parts relates to the field of metal forming, semiautomatic devices for bending parts from piece sheet blanks. Semi-automatic for bending parts can be used when bending U-shaped parts.

A known method of bending parts in stamps on presses. The essence of the bending process in dies is that a flat workpiece under the pressure of the working parts of the stamp is bent and takes their shape.

“Production of dies and molds and devices,” Chapter VIII. Stamping device for cold stamping, fig. 55b. 2nd edition, revised and supplemented. Engineering. Moscow "Higher School", 1974, VV Mikhailovich.

The die matrix is mounted on the press table, and the punch is attached to the upper slider plate, which performs reciprocating movements up and down. Setting up stamps like stamping itself is very time-consuming. When bending parts with manual downloads, as a rule, there is a chance of injury to the worker. Setting stamps requires a lot of preparatory and final time.

Known semiautomatic device for bending products (parts), containing a base on which are mounted two opposite located bending modules (patent for the invention No. 2429931, published September 27, 2011).

Filing blanks manually increases the operational time for the operation and does not exclude the possibility of personal injury.

The closest analogue is a device for bending U-shaped parts from piece sheet blanks containing a base, an engine, a bending module, a storage magazine and a gate (SU 1077681, A1, 03.03.1984, B21D 7/02).

Billets from the drum to the store-drive are served without organoleptic control, which can lead to marriage of finished parts.

The objective of the proposed utility model is to ensure safe working conditions, reducing the complexity of manufacturing.

The technical result is the mechanization of the technological process of bending parts.

The technical result is achieved by the fact that on the basis of the mounted worm gear, kinematically connected to the V-belt drive engine, connected through a safety clutch to the low-speed branch of the worm gear bending module containing a housing with guides, a gate made with a recess-matrix with a through molding hole of a rectangular shape, and installed with the possibility of reciprocating movement in the guides of the housing from the store-drive to the bending zone, springs for return and the gate to the bending zone, the cam mechanism located inside the housing made of three cams, one bending cam-punch and two control cams, the control cams being made with the possibility of rotational movement to provide reciprocating movement of the gate from the store to the bending zone, and the bending cam-punch is located between the control cams and is made with the possibility of rotational movement to enter the through molding hole of the slide matrix of the slide in the bending zone and exit from it with a finished U-shaped part, while the store-drive is made in the form of a shaft, in cross section having the shape of a workpiece.

Bending modules are quickly reinstalled, do not require adjustment. The preparatory-final time is reduced. The supply of the workpiece from the store-drive is carried out without the participation of the worker, that is, the operational time for the operation is reduced, the complexity of manufacturing is reduced. A semiautomatic device for bending parts allows you to do without press equipment, which ensures safe working conditions and ease of use, reduces costs. The mechanization of the technological process of bending parts allowed the worker to reduce the function to loading blanks into a store-drive when the semiautomatic machine for bending is turned off, to work management, quality control, and tool control. The design of the semiautomatic device for bending parts is simple in design and allows for a quick transition without additional changes to another type of product.

The accompanying drawings show a semiautomatic device for bending parts presented on a utility model.

In FIG. 1 - the main view of the semiautomatic device for bending parts (store-drive is not shown); in FIG. 2 is a right side view of a semiautomatic device for bending parts (skliz and storage containers are not shown); in FIG. 3 - bending module in axonometric projection; in FIG. 4 - detail obtained flexible on a semiautomatic device, main view, section; in FIG. 5 - detail obtained flexible on the semiautomatic device, left view.

On the basis of 1, a worm gearbox 2 is mounted kinematically connected to the engine 3 by a V-belt drive 4, connected through a safety clutch 6 to the low-speed branch of the worm gearbox 2, a bending module 5, comprising a housing 7 with guides 8, a gate 9 made with a recess matrix 10 with a through molding hole 11 of a rectangular shape and mounted with the possibility of reciprocating movement in the guides of the housing 7 from the store-drive 14 to the bending zone, springs 15 to return the gate 9 to the bending zone, ra a cam mechanism made of three cams, one bending cam-punch 12 and two control cams 13 located inside the housing 7, and the control cams are rotatable to provide reciprocating movement of the gate 9 from the store 14 to the bending zone, and the bending cam-punch 12 is located between the control cams 13 and is made with the possibility of rotational movement to enter the through molding hole of the recess-matrix 10 of the gate 9 in the bending zone and exit of finished part with a U-shaped form, wherein the store-storage 14 is configured as a shaft, having a sectional shape of the preform.

A semiautomatic device for bending parts works as follows.

Store magazine 14 is loaded manually. The control cams 13, in a rotational movement, push the gate 9 under the magazine store 14, where the workpiece from the magazine store under its own weight falls into the recess-matrix 10 of the gate 9. The gate 9 by springs 15 returns to the bending zone, where the bending cam-punch 12, making rotational movement, runs onto the workpiece and pulls it through the through molding hole 11 of the gate 9. The finished part through the hole in the base plate of the body 16 of the bending module and the base 1 of the semiautomatic device falls along the slit 17 into the storage container 18. For obes echeniya high accuracy bending module has two shims, by means of which cam-bending punch set relatively recess gate matrix.

The claimed semiautomatic device for bending parts allows with insignificant processing to produce a wide range of typical parts by design and shape under semi-automatic production conditions.
