Abstract
The utility model discloses an L-shaped part bending die which comprises a female die, a male die, a die handle and a lower die holder. The male die is fixedly connected to the portion below the die handle. The lower end of the male die is provided with two slopes inclining downwards, wherein the two slopes are the left male die slope and the right male die slope. An L-shaped protrusion is formed by the two slopes. A U-shaped groove is formed in the lower die holder. The female die is arranged in the U-shaped groove. An L-shaped groove attached to the L-shaped protrusion is formed in the upper side of the female die. The upper left side of the female die and the upper left side of the lower die holder are located in the same plane which is a slope, wherein the slope is parallel to the right male die slope. A locating board is arranged on the upper left side of the lower die holder. According to the L-shaped part bending die, a part can not bounce back, the shape and the size of the part are accurate, product accuracy is high, the structure is simple, operation is convenient, and cost is low.
Description
Technical field
The utility model relates to stamping technology field, relates in particular to a kind of L shaped product bending die.
Background technology
L shaped product is a kind of conventional part, conventionally adopts plate to form with bending die bending, and BENDING PROCESS is the process that strain and plastic deformation have concurrently, product often has the phenomenon of resilience after bending, cause product shape and size inaccurate, Product Precision is low, affects product quality.
Utility model content
Problem to be solved in the utility model is, has the defect of rebound phenomenon for the L shaped product of prior art after bending, provides after a kind of L shaped product bending without resilience, and product shape and size are accurate, the L shaped product bending die that Product Precision is high.
The purpose of this utility model is achieved through the following technical solutions.L shaped product bending die, comprise die, punch, die shank, die shoe, punch is fixedly connected on die shank below, the lower end of described punch is provided with two downward-sloping inclined-planes, comprise punch left tilted surface and punch right tilted surface, two inclined-planes form L shaped projection, described die shoe is provided with U-shaped groove, die is arranged in U-shaped die, die upside is provided with the L shaped groove fitting with L shaped projection, die upper left side and die shoe upper left side are at same plane and be inclined-plane, and this inclined-plane is parallel with punch right tilted surface, and die shoe upper left side is provided with location-plate.The blank of product is placed on die, and location-plate makes blank location, and patrix is descending, blank is compressed into die and form L shapedly, after upper and lower mould closure, the L shaped both sides of product are all subject to the active force of punch and die, product is proofreaied and correct, so the up rear product of punch can not produce resilience, product shape and size are accurate, and Product Precision is high, the utility model, simple in structure, easy to operate, cost is low.
As preferably, the right side of described U-shaped groove is provided with baffle plate, and the height of baffle plate is higher than the height of die.During installation, first die is put into the groove of die shoe, then according to the gap on groove right side by the right side of suitable baffle plate fits into groove, the convenient die of installing, the height of baffle plate, higher than the height of die, makes baffle plate play the effect of guiding punch simultaneously.
As preferably, U-shaped groove starts to extend back from the leading flank of die shoe, and the length of extension is less than the length of side before and after U-shaped groove, and the rear side of groove has a sidewall, when die is installed, plays the role of positioning, easy for installation.
As preferably, described die upper left side is provided with pin stop.When the blank of product is placed on die, pin stop makes the rear side location of blank, easy to operate.
The beneficial effects of the utility model are, product can not produce resilience, and product shape and size are accurate, and Product Precision is high, simple in structure, easy to operate, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of counterdie.
The specific embodiment
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment, as shown in Fig. 1 to Fig. 2, L shaped product bending die, patrix and counterdie, consist of, patrix comprises punch 2 and die shank 1, and counterdie comprises die shoe 5, die 4 etc., punch is screwed and is connected to die shank below, the lower end of punch is provided with two downward-sloping inclined-planes, comprises punch left tilted surface and punch right tilted surface, and two inclined-planes form L shaped projection.Die shoe is provided with U-shaped groove, U-shaped groove starts to extend back from the leading flank of die shoe, and the length of extension is less than the length of U-shaped groove front and back side, and the right side of die shoe upper side is horizontal plane, the left side of die shoe upper side is inclined-plane, and this inclined-plane is parallel with punch right tilted surface.Die is arranged in U-shaped die, the bottom surface of die is fixedly connected with die shoe with screw, die upside is provided with the L shaped groove fitting with L shaped projection, die upper left side and die shoe upper left side are at same plane and be inclined-plane, this inclined-plane is parallel with punch right tilted surface, die shoe upper left side is provided with location-plate 3, and location-plate is screwed on die shoe.The right side of U-shaped groove is provided with baffle plate 6, and the height of baffle plate is higher than the height of die, and baffle plate is screwed at die shoe.Die upper left side is provided with a counterbore, and pin stop 7 is fixed in counterbore with counterbore interference fit.During work, the blank of product is placed on die, location-plate and pin stop make blank location, patrix is descending, by blank compress into die form L shaped, after upper and lower mould closure, the L shaped both sides of product are all subject to the active force of punch and die, and product is proofreaied and correct, so the up rear product of punch can not produce resilience, product shape and size are accurate, Product Precision is high, and the utility model is simple in structure, easy to operate, cost is low.
The above is the preferably specific embodiment of the utility model, not with this, limits practical range of the present utility model.The utility model can also have other embodiment, only otherwise deviate from spirit of the present utility model, and within no matter in form what kind of conversion all drops on protection domain of the present utility model.
