Description

Technical Field

[0001] The utility model belongs to the field of forging processing, and particularly relates to a sawing total length control device for long-axis fork-shaped forgings. Background Technique

[0002] At present, in the forging industry, there are many types of long-axis fork-shaped forgings. However, in many cases, the other dimensions of the forgings are basically the same, only the length of the rod part is different. If all are forged separately, regardless of the technological difficulty, the mold cost and material waste alone are a huge consumption. Through communication with customers, it is learned that the customers only require the head strength of the long-axis fork-shaped forgings, and the rod part can meet the basic performance requirements of the material. Based on this, a local heating forging process can be adopted to complete the shaping of the head, and the length can be controlled by sawing to meet the customer's length requirements. For such fork-shaped special-shaped forgings, the current process route is: blanking - local heating - upsetting - pre-forging - final forging - trimming - heat treatment - shot peening - sawing - inspection - warehousing; in the sawing process, due to the local heating forging process of the forgings, the product lengths are different and cannot be accurately controlled, so there is no fixed sawing length, and the sawing length must be determined after measurement, and subsequent inspections must be carried out one by one to ensure the qualification of the products, resulting in a huge workload and a great waste of manpower and material resources.

[0003] Therefore, the above problems should be considered and solved during the production of the above forgings. Content of the Utility Model

[0004] Aiming at the above problems, the purpose of the utility model is to provide a sawing total length control device for long-axis fork-shaped forgings, which mainly solves the problem of the same category but different lengths of long-axis fork-shaped forgings, improves production efficiency, and reduces production costs.

[0005] The specific technical solution of the utility model is as follows: A sawing total length control device for long-axis fork-shaped forgings includes a frame. Above the frame, there is a trough for placing forgings. The trough includes a bottom plate and three side plates surrounding and arranged above the bottom plate. Measuring devices are arranged on both sides of the trough. At one end inside the trough, there is a length adjusting device, and at the other end, there is a height adjusting device. The length adjusting device includes a limiting plate and an adjusting rod. One end of the adjusting rod passes through the trough and is locked by a locking mechanism.

The measuring device includes a scale 8, and the scale 8 is arranged at the tops of the opposite side plates. The length of the scale is longer than the shortest distance after the length adjustment device is shortened.

[0020] At one end inside the trough 5, there is a length adjustment device. The length adjustment device includes a limit plate 9 and an adjustment rod 10. The outer circumference of the adjustment rod 10 is provided with threads. One end of the adjustment rod 10 passes through the trough 5 and is locked by a locking mechanism. The locking mechanism includes a set of locking nuts 11. The locking nuts 11 are sleeved on the adjustment rod 10 and are respectively arranged on the inner and outer sides of the trough 5 for locking and fixing. One end of the adjustment rod 10 is connected to the limit plate 9 through a connecting block 12. Limit blocks 13 are provided on both sides of the limit plate 9, and sliding grooves 14 adapted to the limit blocks 13 are provided on the inner walls of the two opposite side plates 7.

[0021] At the other end inside the trough 5, there is a height adjustment device. The height adjustment device includes a base 15 and a driving device for controlling the lifting of the base 15. The driving device uses a hydraulic cylinder 16, which is arranged below the bottom plate 6.

[0022] A device for controlling the total sawing length of a long-axis fork forging provided in this embodiment has the following working principle: First, in cooperation with the summarized saw total length table, confirm the total length requirement of the long-axis fork forging to be sawn; then measure the length from the outer end face of the limit plate 9 to the saw blade of the sawing machine. If it exceeds or is less than the total length requirement, loosen the locking nut 11 to adjust the distance from the end face of the limit plate 9 to the saw blade of the sawing machine (the total length adjustment range is 200 - 1000 mm, which can be achieved by replacing the lead screw), and lock the locking nut after adjusting the distance; then place the long-axis fork forging 0 to be sawn above the base 15 in the tank body, and after ensuring that the head of the product is in close contact with the end face of the limit plate 9, control the sawing machine to clamp the rod part for cutting (if there is a drop in the rod part, the base 15 can be lifted or lowered as required by the height adjustment device, and ensure that the whole long-axis fork forging is parallel to the bottom of the tank at the horizontal line); finally, keep the clamping state, measure the size of the long-axis fork forging 0, and after meeting the total length size requirement, a large number of sawing materials can be carried out (measure after loosening the clamping state, due to the shaping problem, it is not easy to measure the size accurately). After the first piece is inspected and found to be correct, a large number of sawing materials can be carried out. The whole device adopts the simplest working principle, reduces the operation difficulty, and even a novice can easily get started. In this way, the work efficiency is greatly accelerated, and the dimensional deviation caused by human factors is also reduced to the lowest. Subsequently, it is no longer necessary to conduct a full inspection for dimensional inspection, saving a large amount of labor and time costs while ensuring quality and quantity.
