Abstract
The utility model relates to a hexagonal bolt screw diameter-shrinkage die which includes a lower die seat 6, a diameter-shrinkage die 2, a diameter shrinkage die-to-die 4, a die ejector rod 6, a die ejector rod sleeve 8, a lower seat pad 7, a rear ejector rod 12, a rear ejector rod sleeve 9, a rear ejector rod guide sleeve 10 and an upper parallel cap 1 and a lower parallel cap 11. The diameter-shrinkage die and the diameter-shrinkage die-to-die are sequentially arranged on the lower die seat from top to bottom; the lower die seat is pivotally arranged at an upper end of the die seat pad; the upper parallel cap is pivotally at a top end of the lower die seat; the die ejector rod sleeve and the rear ejector rod sleeve are arranged in the lower die seat pad; a lower part of the die ejector rod is arranged in the die ejector rod sleeve; an upper end of the die ejector rod is inserted into a central hole of the diameter-shrinkage die-to-die; the rear ejector guide sleeve is pivotally arranged at a center of the lower part of the lower die seat pad; the lower parallel cap is pivotally arranged on the rear ejector rod guide sleeve; a front end of the rear ejector rod is inserted into the rear ejector sleeve; the utility model is characterized in that a positioning die combination part 3 is embedded between the diameter-shrinkage die and the diameter-shrinkage die-to-die in the lower die seat. The die can ensure that the rod bend is not formed when the diameter of the rod is shrunk.
Description
Technical field:
The utility model relates to a kind of mould.Particularly relate to a kind of hex bolts screw rod undergauge mould.
Background technology:
Present existing hex bolts screw rod undergauge mould generally connects mould, mould push rod, mould push rod lasso, counterdie seat cushion, back push rod, back push rod lasso, back push rod guide pin bushing by die shoe, reducing die, reducing die and upper and lower and cap is formed.Because the thread billet dia bar portion diameter of hex bolts is less than the aperture of the bar portion reducing die of screw rod undergauge process mould, can not keep bar portion vertical when making the bolt shank undergauge with horizontal direction, in the process of undergauge, can produce and rock the bending of formation bar portion, can not normally finish bar portion undergauge operation.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of hex bolts screw rod undergauge mould that can not form the bending of bar portion can guarantee bar portion undergauge the time is provided.
The purpose of this utility model is achieved in that a kind of hex bolts screw rod undergauge mould, comprise die shoe, reducing die, the positioning module component, reducing die connects mould, the mould push rod, mould push rod lasso, the counterdie seat cushion, back push rod, back push rod lasso, back push rod guide pin bushing and on, following also cap, reducing die, positioning module component and reducing die connect mould and pack into successively from top to bottom in the die shoe, die shoe is spun on counterdie seat cushion upper end, going up also, cap is spun on the die shoe top, mould push rod lasso and back push rod lasso place in the counterdie seat cushion, mould push rod lower end is inserted in the mould push rod lasso, the upper end is inserted in reducing die and connects the mould center, back push rod guide pin bushing is spun in the screw of counterdie seat cushion bottom, also cap is spun on the push rod guide pin bushing of back down, back push rod is inserted in the push rod guide pin bushing of back, and its front end is inserted in the push rod lasso of back.
During operation, the screw thread undergauge bar portion of the hex bolts that will be finished by last process inserts in the positioning module component by the die cavity of reducing die, makes bar portion keep vertical with horizontal direction, can not produce when guaranteeing bar portion undergauge to rock the bending of formation bar portion.
Description of drawings:
Fig. 1 is a general structure schematic diagram of the present utility model.
The specific embodiment:
As Fig. 1, the utility model is a kind of hex bolts screw rod undergauge mould.Mainly connect mould 4, mould push rod 6, mould push rod lasso 8, counterdie seat cushion 7, back push rod 12, back push rod lasso 9, back push rod guide pin bushing 10 and upper and lower and cap 1,11 is formed by die shoe 6, reducing die 2, positioning module component 3, reducing die.Reducing die 2, positioning module component 3 and reducing die connect mould 4 and pack into successively from top to bottom in the die shoe 5.Die shoe 5 is spun on counterdie seat cushion 7 upper ends, and upward also cap is spun on die shoe 5 tops, and reducing die 2, positioning module component 3 and reducing die are connect mould 4 and tight.Mould push rod lasso 8 and back push rod lasso 9 place in the counterdie seat cushion 7, and mould push rod 6 lower ends are inserted in the mould push rod lasso 8, and the upper end is inserted in reducing die and connects in mould 4 centre bores.Back push rod guide pin bushing 10 is spun in the screw of counterdie seat cushion 7 lower central, and also cap 11 is spun on the back push rod guide pin bushing 10 it is also tight down.Back push rod 12 is inserted in the back push rod guide pin bushing 10, and its front end is inserted in the back push rod lasso 9.
