Description

Technical Field

[0001] The utility model relates to the technical field of thread rolling machines, in particular to a hydraulic locking die box. Background Art

[0002] When a thread rolling machine is used to roll threads on bolts, in order to ensure the rolling effect of the thread rolling plate on the bolts, a locking die box is usually set on the thread rolling machine to lock the bolts so that the bolts are always tightly fitted with the thread rolling plate during the thread rolling process. The existing locking die box is usually composed of a feeding mechanism and a locking pressure block.

[0003] For example: The utility model with application number CN201820790332.8 discloses a thread rolling machine for preparing torsion shear type bolts, specifically: including a thread rolling body, a thread rolling die is clamped on the thread rolling body, the thread rolling die includes a thread rolling tooth plate and a torsion shear type cutting knife threadedly connected to the thread rolling tooth plate, the torsion shear type cutting knife includes a cutting knife profile and a strip knife fixedly connected to one side of the cutting knife profile, and the cutting knife profile is provided with a threaded hole threadedly fixed to the thread rolling tooth plate by a positioning bolt. The advantage of the utility model is that the thread rolling die is composed of a thread rolling tooth plate and a torsion shear type cutting knife, so that when the thread rolling machine is working, the threads on the peripheral surface of the torsion shear type bolt are opened, and the connection groove at the plum blossom head connection is also opened, so that the thread rolling machine can complete the work that previously required two different machines to complete, which not only reduces the work process, but also improves the preparation efficiency of the torsion shear type bolts, and also reduces the unnecessary consumption of human resources.

[0004] However, as far as the current traditional locking mold box is concerned, since the locking pressure block will press the bolt against the thread rolling plate during the thread rolling process, the waste chips generated by the thread rolling will easily adhere to the surface of the locking pressure block during the subsequent thread rolling process, affecting the thread rolling effect and making it inconvenient to use. Utility Model Content

[0005] In view of this, the utility model provides a hydraulic locking mold box, which has a telescopic air bag that can automatically clean the waste chips remaining on the surface of the locking pressure block during the resetting process of the locking pressure block. After the locking is completed, the hydraulic cylinder drives the locking pressure block to reset. As the locking pressure block is reset, the control push plate will be squeezed. After the control push plate is squeezed, it will drive the guide slider to slide in the guide slide groove and squeeze the auxiliary spring. During the sliding of the guide slider, it will drive the fixed block to move. During the movement of the fixed block, it will drive the connecting rocker arm to swing. During the swinging of the connecting rocker arm, it will drive the sliding seat to move toward each other along the auxiliary slide bar. During the process of the two sliding seats moving toward each other, the two extrusion push plates will be driven to move toward each other and squeeze the telescopic air bag. After the telescopic air bag is squeezed, the reset locking pressure block will be cleaned through the blowing pipe.

[0006] The utility model provides a hydraulic locking mold box, which specifically includes: a mold box main body; a fixing seat is fixedly connected to the center of the front end of the top end of the mold box main body; the front end surface of the fixing seat is fixedly connected to four connecting sleeves in a rectangular array; a locking pressure block is arranged at the rear of the fixing seat; a mounting seat is fixedly connected to the right end surface of the locking pressure block; a wire passing seat is fixedly connected to the left part of the top end surface of the mold box main body; the position of the wire passing seat is aligned with the fixing seat; a locking seat is fixedly connected to the right part of the top end surface of the mold box main body; the position of the locking seat is aligned with the mounting seat; two guide sliding grooves are symmetrically provided at the rear of the top end surface of the fixing seat.

[0007] Optionally, a guide slide rod is slidably connected in each of the four connecting sleeves; the ends of the four guide slide rods are fixedly connected to the front end face of the locking pressure block; a hydraulic cylinder is bolted in the center of the front end face of the fixed seat; and the end of the hydraulic cylinder output shaft is fixedly connected to the front end face of the locking pressure block.

[0008] Optionally, a guide slider is slidably connected in each of the two guide slide grooves; a control push plate is fixedly connected to the rear end faces of the two guide sliders; the control push plate is aligned with the locking pressure block; two auxiliary springs are symmetrically fixedly connected to the front end face of the control push plate; the ends of the two auxiliary springs are fixedly connected to the outside of the fixed seat.

[0009] Optionally, the top end surfaces of the two guide sliders are fixedly connected to a fixed block; the front end surfaces of the two fixed blocks are hingedly connected to a connecting rocker rod; a group of auxiliary sliding rods are symmetrically fixedly connected to the front end of the top end of the fixed seat; the outside of the auxiliary sliding rods are symmetrically slidably connected to two sliding seats; the ends of the two connecting rocker rods are respectively fixedly connected to the rear end surfaces of the two sliding seats.

[0010] Optionally, an extrusion push plate is fixedly connected to the inner side of the two sliding seats; a telescopic airbag is fixedly connected to the center of the top surface of the fixed seat; the two extrusion push plates are aligned with the position of the telescopic airbag; two supporting seats are symmetrically fixedly connected to the rear of the fixed seat; an air blowing pipe is arranged in each of the two supporting seats; the air inlet ends of the two air blowing pipes are connected to the air outlet of the telescopic airbag, and the air outlet ends of the two air blowing pipes are aligned with the position of the locking pressure block.

[0012] Beneficial Effects

[0013] The utility model discloses locking the bolt by starting the hydraulic cylinder to make the hydraulic cylinder push the locking pressure block to move and lock the bolt. During the movement of the fixed seat, the guide slide bar will be driven to slide in the connecting sleeve to guide the locking pressure block, so that the bolt can fit tightly with the movable thread rolling plate. There is no need for manual adjustment by the staff, and the locking is more convenient and the pressure is greater, which effectively improves the practicability of the hydraulic locking mold box.

[0014] After the locking is completed, as the locking pressure block is reset, it will squeeze the control push plate, and then squeeze the telescopic airbag through a series of transmissions. After the telescopic airbag is squeezed, the reset locking pressure block will be cleaned through the air blow pipe to prevent waste chips from remaining on the locking pressure block, thereby ensuring the cleanliness of the locking pressure block. There is no need for staff to perform secondary cleaning of the locking pressure block, which effectively reduces the labor intensity of staff, improves the thread rolling effect of bolts, improves the convenience of the hydraulic locking mold box, and makes it more convenient to use.
