Abstract
The invention discloses the bolt processing technic featuring that can sense cold-heading charging.The bending of material make it that the length of material that cold-heading equipment shears off is inadequate, causes the scarce material of cold-heading molding of bolt bad.Step of the present invention：Cold-heading wire rod is sent into cold-heading equipment；Controller receives the clock pulses of clock device and the signal of inductor, judges whether cold-heading wire rod front end encounters baffle plate in time T；If time T internal controller receives the signal of inductor, transmission cuts material instruction to cold-heading equipment, and cold-heading equipment starts to cut material；If time T internal controller does not receive the signal of inductor, send halt instruction and shut down to cold-heading equipment, cold-heading equipment；The cold-heading wire rod cut, which enters in cold upsetting die of car, to be molded, and the bolt cold-heading semi-finished product of formation are put into feeding vibration disc vibration, and into thread rolling in the gap of dynamic and static screw plate, form matching thread；Bolt after thread rolling is heat-treated and is surface-treated.The present invention solves during material cold-heading that bolt is molded bad phenomenon caused by bending.
Description
Technical field
The invention belongs to automobile-used technical field of fastening, it is related to automobile-used bolt, and in particular to one kind can sense cold-heading charging
Bolt processing technic featuring.
Background technology
Cold-heading material is after drawing, for ease of transporting and having enough to meet the need, it will usually is being carried by disk into circle, disk round roll material
And in circular flow, easily hindered by forklift, or material occur and stack phenomena such as bending.
And due to the bending of material, cause the length of material that is sheared off during cold-heading by fixed equipment inadequate, easily
Cause the scarce material of cold-heading molding of bolt bad.Therefore, a kind of technique change that can be monitored and cut material length is added during cold-heading
Obtain highly desired.
The content of the invention
The purpose of the present invention be directed to material cold-heading during because material bending and caused by bolt shaping bad phenomenon, carry
For a kind of bolt processing technic featuring for sensing cold-heading charging.
The present invention's comprises the following steps that：
Step 1: inductor is set on the baffle plate of cold-heading equipment, the wire rod transfer passage of inductor alignment cold-heading equipment
End；The timing of clock device and every time T give controller send a clock pulses；Wherein, T takes a value in 5~10s.
Step 2: cold-heading wire rod is sent to after straightening-wheel in the wire rod transfer passage of cold-heading equipment, before cold-heading wire rod
When end touches baffle plate, signal is transmitted to controller by inductor.Controller receives the clock pulses of clock device and the letter of inductor
Number, so as to judge whether the front end of the cold-heading wire rod in time T touches baffle plate.If receive inductor in time T internal controller
Signal, then send cut material instruction to cold-heading equipment, the scissors of cold-heading equipment starts to cut material；If do not received in time T internal controller
To the signal for receiving inductor, then halt instruction is sent to cold-heading equipment, cold-heading equipment, which is shut down, changes cold-heading wire rod.
It is molded Step 3: being entered by the cold-heading wire rod that the scissors of cold-heading equipment is cut in cold upsetting die of car, forms spiral shell
Bolt cold-heading semi-finished product.
Step 4: bolt cold-heading semi-finished product are put into feeding vibrating disk.Feeding vibrates disc vibration, and bolt cold-heading semi-finished product enter
Enter to thread rolling track, and by thread rolling track in the gap of dynamic and static screw plate.
Step 5: dynamic and static screw plate carries out thread rolling to bolt cold-heading semi-finished product.Quiet screw plate is fixed, moves screw plate
It is oppositely arranged with quiet screw plate and is moved back and forth along parallel quiet screw plate direction.Shank of bolt cylinder is mutually rubbed with the hands in dynamic and static screw plate
Matching thread is formed under dynamic.
Step 6: being heat-treated to the bolt after thread rolling, it is heat-treated as quenched or carburizing.
Step 7: be surface-treated to the bolt after heat treatment, be surface-treated for surface is zinc-plated, at coating or phosphatization
Reason.
The present invention solve during material cold-heading because material bending and caused by bolt shaping bad phenomenon.
Embodiment
The present invention is described in detail with reference to embodiment.
The bolt processing technic featuring of cold-heading charging can be sensed, comprised the following steps that：
Step 1: inductor is set on the baffle plate of cold-heading equipment, the wire rod transfer passage of inductor alignment cold-heading equipment
End；The timing of clock device and every time T give controller send a clock pulses, T value is 5s.
Step 2: cold-heading wire rod is sent to after straightening-wheel in the wire rod transfer passage of cold-heading equipment, before cold-heading wire rod
When end touches baffle plate, signal is transmitted to controller by inductor.Controller receives the clock pulses of clock device and the letter of inductor
Number, so as to judge whether the front end of the cold-heading wire rod in time T touches baffle plate.If receive inductor in time T internal controller
Signal, then send cut material instruction to cold-heading equipment, the scissors of cold-heading equipment starts to cut material；If do not received in time T internal controller
To the signal of inductor, then send halt instruction and shut down to cold-heading equipment, cold-heading equipment, it is artificial to change or cut cold-heading wire rod
Bend part.Because straight cold-heading wire rod front end can just touch inductor, and the cold-heading wire rod bent does not reach sensing
Device, therefore, only straight cold-heading wire rod just can cause inductor to transmit a signal to controller in time T.
It is molded Step 3: being entered by the cold-heading wire rod that the scissors of cold-heading equipment is cut in cold upsetting die of car, forms spiral shell
Bolt cold-heading semi-finished product.
Step 4: bolt cold-heading semi-finished product are put into feeding vibrating disk.Feeding vibrates disc vibration, and bolt cold-heading semi-finished product enter
Enter to thread rolling track, and by thread rolling track in the gap of dynamic and static screw plate.
Step 5: dynamic and static screw plate carries out thread rolling to bolt cold-heading semi-finished product.Quiet screw plate is fixed, moves screw plate
It is oppositely arranged with quiet screw plate and is moved back and forth along parallel quiet screw plate direction.Shank of bolt cylinder is mutually rubbed with the hands in dynamic and static screw plate
Matching thread is formed under dynamic.
Step 6: be heat-treated to the bolt after thread rolling, it is heat-treated as quenched or carburizing, reaches the hardness number of bolt
It is required that.
Step 7: be surface-treated to the bolt after heat treatment, be surface-treated for surface is zinc-plated, at coating or phosphatization
Reason.
