Abstract
A thick plate part deep-U-shaped rolling bending die structure comprises an upper base plate, a terrace die, a roller, a recessed die, a recessed die fixing plate, a jacking device, a support rod, a location pin, a stopping block and a lower base plate. The terrace die is fixed on the upper base plate, the roller is installed in the recessed die, the stopping block is installed at the end of the recessed die, the recessed die is installed in a recessed die fixing plate cavity, the recessed die is fixed on the side of the recessed die fixing plate through a screw, the location pin is fixed on the jacking device which is installed in a recessed die cavity, and the support rod is installed in the lower base plate. The sliding friction is changed to be rolling friction, friction resistance of parts in the deformation process is greatly reduced, part friction heating condition is reduced, the parts are fully lubricated in the deformation process, flow accumulation caused by the peeling effect and the bonding effect is fundamentally removed in the machining process, the shortcoming of part galling is overcome, and product machining quality is ensured. The structure improves production efficiency and is simple in structure and convenient to manufacture and maintain.
Description
Technical field
The utility model belongs to metal forming punch process field, relates to a kind of mould structure, relates in particular to the dark U-shaped rolling of a kind of thick-plate parts bending die structure.
Background technology
At present, the most of mechanic factory workers of China, in the punch process of metallic article, carry out dark U-shaped press-bending to thick-plate parts.Traditional bending die structure is to adopt the mode of bending of sliding to process, because the press-bending degree of depth is higher, in production and processing, part often easily produces galling defect, and the part after processing need to carry out polishing, thereby affect production efficiency, and be difficult to ensure the quality of product.Therefore, development is a kind of rational in infrastructure, easy to use and reliable, ensures processing work quality, and the dark U-shaped rolling of the thick-plate parts bending die structure that the workpiece after subduction processing carries out polishing is completely necessary.
Utility model content
The purpose of this utility model is to provide the dark U-shaped rolling of a kind of rational in infrastructure, easy to use and reliable thick-plate parts bending die structure, and by design roller press-bending structure, the dark U-shaped that completes thick-plate parts bends and processes.
The technical solution of the utility model is: the dark U-shaped rolling of thick-plate parts bending die structure, comprising: upper plate, punch, roller, die, die block, backing-out punch, pressure pin, alignment pin, block, lower shoe; Punch is fixed on upper plate, and roller is contained in die, and block is installed in die termination, die packs in die block chamber, and is screwed die from die block side, and alignment pin is fixed on backing-out punch, backing-out punch installs in matrix cavity, and pressure pin packs in lower shoe.
The utility model adopts the good effect of obtaining after technique scheme to be: the dark U-shaped rolling of thick-plate parts bending die structure, become rolling friction from original sliding friction, greatly reduce the frictional resistance of part in deformation process, alleviate part frictional heating situation, can make part fully be lubricated in deformation process simultaneously, substantially eliminated the long-pending flow phenomenon being caused by plough-effect and sticking effect in process, the galling defect of having eliminated part, has ensured product processing quality.Improved production efficiency, this mould structure is simple, manufacture and easy to maintenance, and this mould structure is applicable to produce in enormous quantities.
Brief description of the drawings
Fig. 1 is the structural profile schematic diagram of the dark U-shaped rolling of the utility model thick-plate parts bending die structure.
Fig. 2 is the plan structure schematic diagram of the dark U-shaped rolling of the utility model thick-plate parts bending die structure.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings below.As shown in Figure 1 and 2, the dark U-shaped rolling of thick-plate parts bending die structure, mainly comprises: upper plate 1, punch 2, roller 3, die 4, die block 5, backing-out punch 6, pressure pin 7, alignment pin 8, block 9, lower shoe 10; Punch 2 is fixed on upper plate 1, forms patrix; Roller 3 is contained in die 4, can be in the interior rolling of die 4, block 9 is installed in termination, prevent that roller 3 from scurrying out, in die 4, pack in die block 5 chambeies, and be screwed die 4 from die block 5 sides, alignment pin 8 is fixed on backing-out punch 6, backing-out punch 6 installs in die 4 chambeies, and pressure pin 7 packs in lower shoe 10.
When work: pressure pin 7 ejects backing-out punch 6 with die 4 and flushes under the effect of equipment air cushion, slab workpiece is placed on die 4 and backing-out punch 6, locates by alignment pin 8; Patrix is descending, and punch 2 first compresses part with backing-out punch 6, forms precompressed and prevents part unstability, patrix continues descending, and part, under the clamping of punch 2 and backing-out punch 6, is advanced under continuation in die 4, until backing-out punch 6 touches lower shoe 10, complete dark U-shaped and bend.In this process, part and roller 3 produce friction, have reduced the frictional resistance in part deformation process, have alleviated part frictional heating situation.Simultaneously can make part fully be lubricated in deformation process, substantially eliminated the long-pending flow phenomenon that the plough-effect that produces and sticking effect cause in process, eliminate the galling defect of part.Patrix is up, and backing-out punch 6 ejects product.
In punching production, utilize the dark U-shaped rolling of this thick-plate parts bending die structure, mould structure is simply compact, solid durable, and manufacture and easy to maintenance, can be good at ensureing product quality, has reduced artificial production cost, has improved significantly production efficiency.
