Technical Field
The utility model relates to a forge processing technology field, especially relate to a long hammering block is drawn out in forging of large-scale tool and die flat steel forging.
Background
The tool and die steel is used as an important tool for equipment manufacturing and part processing, and has wide market demand due to excellent performance.
At present, common tool and die flat steel drawing anvils are upper and lower flat anvils, the drawing forging state of the common tool and die flat steel drawing anvils is shown in figures 1 and 2 of drawings in the specification, the problem that drawing efficiency is too low in a finished product drawing stage of the upper and lower flat anvils used in the prior art is solved, the workpiece returning times and high-temperature heating time are increased, energy waste and cost are increased, and too long heating time in the high-temperature stage brings difficulties for subsequent heat treatment.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's not enough, provide a forging of large-scale tool and die flat steel forging and pull out long hammering block, improved traditional tool and die flat steel and forged and pull out long efficiency, through forging the deformation between the upper and lower hammering block that improves the upgrading, effectively improved forging shaping speed, reduce the fire number, really realize carrying and imitate the consumption reduction.
The utility model discloses a through following technical scheme realizes, provides a large-scale tool and die flat steel forging draws out long hammering block, two step hammering blocks that the longitudinal symmetry set up, every step hammering block all include first hammering block face and second hammering block face, and the second hammering block face is higher than first hammering block face, and second hammering block face and first hammering block face are through connecting the face and connect, connect the face including the first cambered surface and the second cambered surface that link together, first cambered surface is connected with first hammering block face, and the second cambered surface is connected with the second hammering block face, and the radius of first cambered surface and second cambered surface is the same, and the centre of a circle of first cambered surface is located between two step hammering blocks, and the centre of a circle of second cambered surface is located the step hammering block.
Preferably, the height difference H between the second anvil surface and the first anvil surface is 25 mm.
Preferably, the radius R of the first cambered surface and the radius R of the second cambered surface are both 100 mm.
The utility model has the advantages that:
1. the efficiency of traditional tool and die flat steel forging drawing is improved, through forging deformation between the upper and lower hammering blocks that improve the upgrading, effectively improved forging piece shaping speed, reduce the number of times of a fire, really realize promoting effects and reduce consumption.
2. Compared with the traditional flat anvil, the contact surface between the step anvil and the forge piece is increased, and the reduction of each pass is increased, so that the reduction efficiency of the forge piece at each anvil in the finished product drawing stage is effectively increased, the drawing speed is improved, the heat frequency is reduced, the energy consumption is reduced, and the win-win quality and benefit is realized.
3. Compared with the prior production module, the production module of the stepped anvil has the advantages that the edge angle effect and the flatness of each plane are kept very good, more importantly, the forging time is greatly reduced, the fire frequency is reduced, and good benefits are brought to enterprises.
4. The first cambered surface and the second cambered surface at the root of the step are added, so that the folding in the pressing process is avoided.

Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 3 and 4, the utility model discloses a two step anvils 1 that the longitudinal symmetry set up, every step anvils 1 all include first hammering block face 2 and second hammering block face 3, and second hammering block face 3 is higher than first hammering block face 2, and second hammering block face 3 and first hammering block face 2 are connected through connecting the face, connect the face including first cambered surface 4 and the second cambered surface 5 that link together, first cambered surface 4 is connected with first hammering block face 2, and second cambered surface 5 is connected with second hammering block face 3, and first cambered surface 4 is the same with the radius of second cambered surface 5, and the centre of a circle of first cambered surface 4 is located between two step anvils 1, and the centre of a circle of second cambered surface 5 is located anvil step 1.
In this embodiment the height difference H between the second anvil surface 3 and the first anvil surface 2 is 25 mm.
In the present embodiment, the radii R of the first cambered surface 4 and the second cambered surface 5 are both 100 mm.
When the steel ingot drawing machine is used specifically, after the steel ingot 6 is heated to the temperature according to the special heating specification, upsetting and pre-drawing are carried out according to the forging process requirement, the steel ingot 6 is drawn to be long through the hydraulic press provided with the upper and lower step anvils 1, the installation mode of the upper and lower step anvils 1 and the hydraulic press is the same as that of the traditional flat anvil and the hydraulic press, and therefore the installation mode is not repeated. As the contact surface of the step anvil 1 and the forge piece is increased, the reduction of each pass is increased, so that the reduction efficiency of each anvil of the forge piece in the finished product drawing stage is effectively increased, the drawing speed is increased, the forge piece is gradually drawn to the size of the finished product.
Of course, the above description is not limited to the above examples, and technical features of the present invention that are not described in the present application may be implemented by or using the prior art, and are not described herein again; the above embodiments and drawings are only used for illustrating the technical solutions of the present invention and are not intended to limit the present invention, and the present invention has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that changes, modifications, additions or substitutions made by those skilled in the art within the spirit of the present invention should also belong to the protection scope of the claims of the present invention.
