Abstract
The utility model relates to a load-bearing main board of a hot press, in particular to a main board for bearing the force during the working process of the hot press, which belongs to the field of mechanical equipment. The main board is provided with a board body, a hollow filling grate is arranged in the middle of the board body, and the left and the right inner side surfaces of the filling grate are curved surfaces. By using the main board with the structure, the utility model enables the stress of the load bearing part of the main board to be evenly distributed during the working process, thoroughly solves the problem that the corner part of the filling grate of the main board of the hot press cracks under the long-term concentrated stress, greatly prolongs the service life of the main board and improves the operating efficiency of the hot press.
Description
Technical field
The utility model relates to the press apparatus field, the mainboard of load when particularly hot press is worked.
Background technology:
Traditional as shown in Figure 1 frame-type hot press frame, its main load-carrying member---mainboard mostly is steel plate structure when work, and empty gantry, workspace shelves that are are opened in the centre of mainboard, and the left and right side of gantry shelves is the horizontal vertical face.The load mainboard of this structure is after using a period of time, and four angles of gantry shelves produce cracking under the effect of alternate stress.If want to lengthen working hours (life-span) generally take to increase the thickness of force-bearing steel plate, thereby can make that usage ratio of equipment significantly reduces, increase the production cost of equipment and the weight of equipment." design of hydraulic press and application " (Yu Xinlu chief editor, China Machine Press publishes, in April, 2007 front page) in the book, author's finite element theory of giving chapter and verse calculates, the structure stress situation that shelves four angles in gantry are upper and lower concave arc is best.But this structure still can't thoroughly solve stress and concentrate on the bight cracking problem that the bight causes after using a period of time.
Summary of the invention
At conventional frame formula hot press shelves bight, force-bearing steel plate gantry problem easy to crack, the purpose of this utility model is to provide a kind of mainboard of heating press, the distribution of the alternate stress in the time of can effectively adjusting force bearing plate work thoroughly solves shelves bight, hot press gantry cracking problem.
For achieving the above object, the technical solution of the utility model is as follows:
Mainboard of heating press has plate body, is gantry shelves of hollow in the middle of the plate body, and the left and right sides medial surface of gantry shelves is an arc-shaped curved surface.After gantry shelves Right Inboard face was set to arc-shaped curved surface, near the suffered stress distribution of plate body during work about the shelves of gantry was even, and maximum stress appears at middle part rather than bight, has solved the cracking problem in bight the most easy to crack preferably.
The radian of inboard arc-shaped curved surface is between 10 degree～150 degree about the shelves of gantry.In practice, the size of radian is subjected to the influence of mainboard size, gantry shelves size.
The radian scope of the arc-shaped curved surface after further optimizing is between 20 degree～120 degree.
Plate body near arc-shaped curved surface is provided with stiffener.After being set, stiffener will prolong working life better.
The beneficial effects of the utility model are: solved mainboard of heating press preferably and too concentrated and the problem of easy cracking in bight, the shelves left and right sides, gantry stress, improved service life, the operating efficiency of hot press greatly.
Description of drawings
Fig. 1 is the schematic diagram of traditional hot press load mainboard;
Fig. 2 is a hot press load mainboard schematic diagram of the present utility model.
Among the figure, 1 is plate body, and 2 is gantry shelves, and 3 is arc-shaped curved surface, and 4 is stiffener.On the plate of the shelves left and right sides, gantry, provided the hot press signal of stress distribution at work among the figure.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model:
As shown in Figure 2, load as required and workspace size are made mainboard of heating press, select the plate body 1 of the Q235 structural carbon steel of 70mm thickness as mainboard of heating press, gantry shelves 2 as the workspace in the middle of the plate body 1 are formed by the line cutting processing, and the left and right sides medial surface of gantry shelves is an arc-shaped curved surface 3.On the plate body 1 on both sides arc-shaped curved surface 3 sides, be welded with stiffener 4 respectively.The radian of inboard arc-shaped curved surface is at 30 degree about the shelves of gantry.
Referring to Fig. 1, the maximum stress among the figure concentrates on shelves bight, gantry, via computer simulation, calculates that with COSMOSXpressStudy software maximum stress also is yield point σ s=399.5MPa.
Referring to Fig. 2, the maximum stress among the figure concentrates on shelves arc-shaped curved surface middle part, gantry, via computer simulation, calculates that with COSMOSXpressStudy software maximum stress also is yield point σ s=220.6MPa.
More than two kinds of situations all adopt the carbon steel plate of Q235, same thickness to do contrast to calculate.
Gantry of the present utility model shelves load plate body maximum stress concentration degree is hanged down 1.8 times than traditional.
It is pointed out that the utility model not only is confined to hot press, the load mainboard of relatively large press is also within protection domain of the present utility model.
