Abstract
The invention discloses a bolt processing process capable of sensing cold heading feeding. The material cut by cold heading equipment is not sufficient in length due to bending of the material, so that cold heading forming of bolts is insufficient and poor. The process comprises the steps that a cold heading wire rod is put into the cold heading equipment; a controller receives clock pulses of a clock and signals of a sensor and judges whether the front end of the cold heading wire rod touches a baffle within the time T or not; if the controller receives the signals of the sensor within the time T, the controller sends a material cutting instruction to the cold heading equipment and the cold heading equipment begins to cut the material; if the controller does not receive the signals of the sensor within the time T, the controller sends a halt instruction to the cold heading equipment, and the cold heading equipment halts; the cut-off cold heading wire rod enters a cold heading mould to be formed, a formed bolt cold heading semi-finished product is put on a feeding vibration disc to vibrate and enters the gap between a movable thread rolling board and a fixed thread rolling board for thread rolling, and matched threads are formed; and a bolt with the threads rolled are subjected to thermal treatment and surface treatment. The phenomenon that the forming of the bolts is poor due to bending in the material cold heading process is avoided.
Description
Technical field
The invention belongs to automobile-used technical field of fastening, relate to automobile-used bolt, be specifically related to a kind of bolt processing technic featuring responding to cold-heading charging.
Background technology
Cold-heading material is after drawing, and for ease of transport and turnover, usually can be coiled circular, dish circle coiled strip, in carrying and circular flow, is easily hindered by forklift, or occurred the phenomenons such as material stacks press-bending.
And bending due to material, cause the length of material that the equipment of being fixed shears off in cold-heading process inadequate, easily cause the cold-heading molding of bolt to lack material bad.Therefore, in cold-heading process, add a kind of technique of cutting material length of can monitoring to become and very need.
Summary of the invention
The object of the invention is, for the shaping bad phenomenon of bolt caused because of material bending in material cold-heading process, to provide a kind of bolt processing technic featuring responding to cold-heading charging.
Concrete steps of the present invention are as follows:
Step one, inductor is set on the baffle plate of cold-heading equipment, the wire rod transfer passage end of inductor alignment cold-heading equipment; Clock device timing and per interval T sends a clock pulses to controller; Wherein, T gets a value in 5 ~ 10s.
Step 2, cold-heading wire rod are sent in the wire rod transfer passage of cold-heading equipment after straightening-wheel, and when the front end of cold-heading wire rod touches baffle plate, signal is passed to controller by inductor.The clock pulses of controller receive clock device and the signal of inductor, thus judge whether the front end of cold-heading wire rod in time T touches baffle plate.If receive the signal of inductor in time T internal controller, then send and cut material instruction to cold-heading equipment, the scissors of cold-heading equipment starts to cut material; If receive the signal of inductor in time T internal controller, then send halt instruction to cold-heading equipment, cold-heading equipment downtime changes cold-heading wire rod.
Step 3, entered into cold upsetting die of car by the cold-heading wire rod that the scissors of cold-heading equipment is cut and carry out shaping, form bolt cold-heading semi-finished product.
Step 4, bolt cold-heading semi-finished product put into material loading vibrating disk.Material loading vibrating disk vibrates, and bolt cold-heading semi-finished product enter into thread rolling track, and are entered by thread rolling track in the gap of dynamic and static screw plate.
Step 5, dynamic and static screw plate carry out thread rolling to bolt cold-heading semi-finished product.Quiet screw plate maintains static, and dynamic screw plate is oppositely arranged with quiet screw plate and moves back and forth along parallel quiet screw plate direction.Shank of bolt cylinder forms matching thread under the mutual rubbing of dynamic and static screw plate.
Step 6, heat-treat the bolt after thread rolling, heat treatment is modified or carburizing.
Step 7, carry out surface treatment to the bolt after heat treatment, surface treatment is plating zinc on surface, coating or phosphorating treatment.
The invention solves the shaping bad phenomenon of bolt caused because of material bending in material cold-heading process.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in detail.
Can respond to the bolt processing technic featuring of cold-heading charging, concrete steps are as follows:
Step one, inductor is set on the baffle plate of cold-heading equipment, the wire rod transfer passage end of inductor alignment cold-heading equipment; Clock device timing and per interval T sends a clock pulses to controller, the value of T is 5s.
Step 2, cold-heading wire rod are sent in the wire rod transfer passage of cold-heading equipment after straightening-wheel, and when the front end of cold-heading wire rod touches baffle plate, signal is passed to controller by inductor.The clock pulses of controller receive clock device and the signal of inductor, thus judge whether the front end of cold-heading wire rod in time T touches baffle plate.If receive the signal of inductor in time T internal controller, then send and cut material instruction to cold-heading equipment, the scissors of cold-heading equipment starts to cut material; If do not receive the signal of inductor in time T internal controller, then send halt instruction to cold-heading equipment, cold-heading equipment downtime, the press-bending part of artificial replacing or cutting cold-heading wire rod.Because straight cold-heading wire rod front end just can touch inductor, and bending cold-heading wire comes into contact is less than inductor, therefore, only have straight cold-heading wire rod just can make inductor in time T transmission signal to controller.
Step 3, entered into cold upsetting die of car by the cold-heading wire rod that the scissors of cold-heading equipment is cut and carry out shaping, form bolt cold-heading semi-finished product.
Step 4, bolt cold-heading semi-finished product put into material loading vibrating disk.Material loading vibrating disk vibrates, and bolt cold-heading semi-finished product enter into thread rolling track, and are entered by thread rolling track in the gap of dynamic and static screw plate.
Step 5, dynamic and static screw plate carry out thread rolling to bolt cold-heading semi-finished product.Quiet screw plate maintains static, and dynamic screw plate is oppositely arranged with quiet screw plate and moves back and forth along parallel quiet screw plate direction.Shank of bolt cylinder forms matching thread under the mutual rubbing of dynamic and static screw plate.
Step 6, heat-treat the bolt after thread rolling, heat treatment is modified or carburizing, makes the hardness number of bolt reach requirement.
Step 7, carry out surface treatment to the bolt after heat treatment, surface treatment is plating zinc on surface, coating or phosphorating treatment.
