Abstract
The invention relates to a calendaring rib structure used on the calendaring die of a large and medium-size covering piece. The structure forms a novel calendaring rib through a plurality of continuously arranged bulb column bolts; the extending height of each bulb column bolt can be adjusted through a screw thread, which realizes the requirement that the extending height of each point of the whole calendaring rib can be adjusted and also namely the requirement of a calendaring deformation area to various pulling stresses; thereby the distribution of the material entering a cavity die in the process of the calendaring is led to be more uniform and reasonable. The adjustment is simple and reliable. Adjustment can be carried out in a punching field according to calendaring conditions.
Description
Affiliated technical field
The invention belongs to the cold stamping shaped technical field of thin plate, is the basic structure of big-and-middle-sized irregular sheet part calendering mould.
Background technology
Big-and-middle-sized irregular sheet part usually can take place wrinkling in the calendering formation process, breaks, and warpage etc. influence the carrying out of calender line and the normal delivery of inter process.On the blank holder of tradition calendering mould, usually improve the tension in shape zone, limit, the stress state of control thin plate each deformed region slab interior in calender line, the feasible quantity of material evenly reasonable (seeing accompanying drawing 1) that enters die by increase calendering muscle.The design of calendering muscle often relies on designer's experience design, and comes the size and the quantity of calendering muscle to be made amendment processing by die trial.Waste time and energy, and often do not reach perfect condition.
Summary of the invention
Die hole periphery has different tension requirements everywhere to deformed region when drawing, and traditional calendering muscle is to be designed to strip be distributed in around the die hole, its length and height h are nonadjustable, and the tension that produces when that is to say calendering is nonadjustable.Owing to can adjust the size of tension by the height h that adjusts the calendering muscle.For this reason, the present invention will roll muscle and be transformed into bulb cylinder screw, arrange continuously a week along die hole periphery, form a continuous and adjustable for height calendering muscle (seeing accompanying drawing 2).Thereby solved the nonadjustable problem of tension that traditional calendering muscle produces.Controlled effectively thin plate in calender line each deformed region to the requirement of tension.Make the quantity of material that enters die be more evenly distributed rationally.Better controlled wrinklingly, broken and calendering such as warpage forming defect.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is a tradition calendering muscle structure chart.
1. screw, 2. die, 3. punch, 4. calendering muscle, 5. blank holder.
Accompanying drawing 2 is the continuous and adjustable for height calendering muscle structure charts of multiple spot of the present invention.
1. ball roller screw, 2. die, 3. punch, 4. blank holder, 5. calendering muscle.
The specific embodiment
In Fig. 2, ball roller screw (1) is fixed on by being threaded on the blank holder (4), and stretching out of ball roller screw (1) highly can use spanner to regulate.In the sheet forming process, die (2) at first contacts with blank holder (4), and makes the plate of ball roller screw (1) top partly be out of shape.Thereupon, punch (3) motion contacts with die (2), plate deforms between die (2) and punch (3), the plate that causes blank holder (4) top is to in-draw, at this moment, be distributed in the height that stretches out of each ball roller screw (1) above calendering muscle (5) by adjusting, can so that the periphery in sheet metal deformation zone inwardly tensile force evenly distribute, thereby the qualified product that obtains conforming to quality requirements.
Claims (4)
1. one kind is rolled the calendering muscle structure of using on the mould, constitutes novel calendering muscle by a plurality of ball roller screws of arranging continuously along the die hole, and the each point on the calendering muscle stretches out highly all and can adjust.It is characterized in that stretch out height-adjustable at every, continuous multiple spot stretches out adjustable height and constitutes novel calendering muscle structure.
2. calendering muscle structure according to claim 1 is characterized in that: ball roller screw also can be structures such as billet muscle.
3. according to claim 1,2 described calendering muscle structures, it is characterized in that: Height Adjustment can adopt other structures such as pad.
4. according to claim 1,2,3 described calendering muscle structures is characterized in that: distribution can continuously also can be discontinuous.
