Description

Top support adjusting device for forming machine

Technical Field

The utility model relates to a make-up machine field specifically is a top support adjusting device for make-up machine.

Background

Compared with castings and forgings, the stamping part has the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with reinforcing ribs, stamped ribs, undulations or flanges that are otherwise difficult to manufacture, to increase their rigidity. Because of the adoption of the precise die, the precision of the workpiece can reach the micron level, the repeated precision is high, the specification is consistent, and the hole nest, the boss and the like can be punched. Cold stamped parts are generally no longer machined or only require a small amount of machining. The precision and the surface state of the hot stamping part are lower than those of a cold stamping part, but are still better than those of a casting and a forging, and the cutting processing amount is small.

The stamping is an efficient production method, and a plurality of stamping processes can be completed on one press (single-station or multi-station) by adopting a compound die, particularly a multi-station progressive die, so that the full-automatic production from uncoiling, flattening, blanking to forming and finishing of a strip is realized. High production efficiency, good working conditions and low production cost, and can produce hundreds of pieces per minute generally. Stamping has many unique and advantageous stamping points, both technically and economically, compared to other methods of machining and plastic working. The main expression is as follows: the punching processing has high production efficiency, convenient operation and easy realization of mechanization and automation. The punching is completed by a punching die and punching equipment, the stroke frequency of a common press can reach dozens of times per minute, the high-speed pressure can reach hundreds of times per minute and even more than thousands of times per minute, and a punching piece can be obtained by each punching stroke; during stamping, the die ensures the size and shape precision of the stamping part, the surface quality of the stamping part is generally not damaged, and the service life of the die is generally longer, so that the stamping quality is stable, the interchangeability is good, and the die has the characteristic of being the same as one die; the stamping can be used for processing parts with larger size range and more complex shapes, such as a stopwatch of a clock, a longitudinal beam of an automobile, a covering part and the like, and the stamping strength and rigidity are higher due to the cold deformation hardening effect of the material during stamping; the stamping is generally free from the generation of chips and scraps, the material consumption is less, and other heating equipment is not needed, so that the method is a material-saving and energy-saving processing method, and the cost of the stamping is lower.

Due to the superiority of stamping, the stamping process has wide application range in various fields of national economy. For example, in aerospace, aviation, military industry, machinery, agricultural machinery, electronics, information, railway, post and telecommunications, traffic, chemical engineering, medical appliances, household appliances, and light industry, stamping is performed. Not only is it used throughout the industry, but everyone is directly linked to the stamped product. Like airplanes, trains, automobiles and tractors, there are many large, medium and small stamped parts. The car body, the frame and the rim of the car are all processed by punching. According to relevant investigation statistics, 80% of bicycles, sewing machines and watches are stamped parts; 90% of the video cameras are stamping parts; metal food can shells, steel-finished boilers, enamel bowls and stainless steel tableware are all stamping products using dies; the stamping parts are not available in the hardware of the computer.

The top support of the existing punching forming machine is generally fixed, and the structure has certain advantages, such as that the fixed top support effectively improves the structural strength, however, under the condition that the top support with different heights according to the punched workpiece is needed, the forming machine with different specifications needs to be replaced, and the condition is not friendly to a small-sized processing plant.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a top support adjusting device for make-up machine to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a top support adjusting device for a forming machine comprises guide shafts, movable sleeves, gears, thrust ball bearings, locking nuts and a top support, wherein the guide shafts are arranged at four corners of the top support, the movable sleeves are connected to the guide shafts in a threaded mode, and the connection relation between the guide shafts and the movable sleeves is similar to that between a screw and a nut in a ball screw; the top of the movable sleeve is provided with a gear, the movable sleeve and the gear are integrally formed, a butting ring is arranged below the gear, the butting ring and the movable sleeve are integrally formed, a gasket is arranged below the butting ring, the top of the gasket is butted with the bottom of the butting ring, and the lower end of the gasket is butted with the top of the top bracket; the four corners of the top support are provided with movable holes for penetrating through the movable sleeves, the movable holes are in interference fit with the movable sleeves, and the inner walls of the movable holes are not in contact with the side walls of the movable sleeves; the locking nut is in threaded connection with the bottom of the movable sleeve, the thrust ball bearing is located between the locking nut and the top support, the lower end of the thrust ball bearing is abutted to the top of the locking nut, and the upper end of the thrust ball bearing is abutted to the top support.
