Description

TECHNICAL FIELD

[0001] The application relates to the technical field of titanium disc part processing equipment, in particular to a forming device and method for pressing and forming a porous titanium dioxide disc part. BACKGROUND

[0002] The porous titanium dioxide disc part is a disc-shaped functional material with a rich pore structure and taking titanium dioxide as a base material, and the pore size covers micropores, mesopores and macropores. The specific surface area can reach tens to hundreds of square meters per gram. In addition, owing to good chemical stability and biocompatibility, the porous titanium dioxide disc part has application potential in the fields of drug release and biological detection in biological medicine. The disc-shaped form is convenient for fixing, installation and operation, and is suitable for various reaction devices and detection equipment, and is an advanced material with structural advantages and functional characteristics.

[0003] The titanium disc part pressing and forming device is a special equipment for processing titanium metal raw materials into disc-shaped parts. The device mainly makes titanium materials plastically deform in the mold to obtain the required shape and size through the action of pressure. The device is usually powered by a hydraulic or mechanical transmission system, and can generate a pressing force of thousands of tons to ensure that the titanium material is fully compacted and formed. The upper and lower molds are designed according to the size and precision requirements of the disc part, are made of high-strength and high-temperature mold steel, and are precisely processed and heat treated. The surface has high smoothness and strong wear resistance, and can accurately control the thickness, diameter and flatness of the disc part.

[0004] During work, the pretreated titanium metal blank is placed in the lower mold, and the upper mold is slowly pressed down under the action of pressure, and heat pressing is realized by cooperating with the heating system to improve the plasticity of titanium and reduce the forming difficulty. Some devices are equipped with a cooling system to rapidly cool and set after forming to prevent disc part deformation. The device also integrates an intelligent control system to monitor parameters such as pressure, temperature and displacement in real time, and ensures the stability of the pressing process through closed-loop adjustment. Some high-end models support multi-stage pressing process and are suitable for the production of titanium disc parts with complex structures. The device is widely used in the manufacturing of titanium alloy disc parts in the fields of aerospace, chemical industry and energy, and is a key equipment for ensuring the high precision and high performance of titanium disc parts.

[0005] Before the existing titanium disc part pressing equipment processes the material, the raw material needs to be cut to a specified size by a cutting mechanism, and then transported to the pressing station by a conveying device such as a conveyor belt or a mechanical arm. This segmented process of "cutting-transporting" has significant process redundancy. The single cutting operation includes positioning and cutting, and takes about 20-30 seconds. The material transportation and secondary positioning take 15-25 seconds. According to the single batch processing of 50 pieces, the cumulative non-production time is increased by 15-25 minutes. Compared with the integrated processing mode, the production cycle of the titanium disc part is prolonged by 12%-20%. The process splitting not only reduces the equipment utilization rate, but also increases the risk of scratches caused by material turnover, which increases the scrap rate by 0.8%-1.5%. Therefore, a forming device and method for pressing and forming a porous titanium dioxide disc part are proposed. SUMMARY

[0025] In summary, the technical effects and advantages of the present application are:

[0026] 1、In the present application, by setting up the pressing device composed of upper die, lower die, hydraulic cylinder one, hydraulic cylinder two, shaping head and air pump system, a strip-shaped material "cutting-shaping" integrated processing system is constructed: the hydraulic cylinder one drives the upper die and the lower die to form a precise cutting station, after the strip-shaped material penetrates the cutting area, it is directly pushed by the hydraulic cylinder two to complete the disc-shaped pressing in situ, the air pump forms negative pressure adsorption with the air box through the tee joint, and the workpiece is grabbed synchronously during the lifting of the shaping head, the device integrates the traditional three-stage process of "cutting-transporting-shaping" in a single station, through the cooperation of die positioning accuracy (±0.03mm) and hydraulic cylinder thrust control (10-15MPa adjustable), the deformation loss and positioning deviation caused by material transfer are eliminated, the yield is improved; the dynamic adsorption mechanism of the air pump ensures the damage-free transfer of the shaped workpiece, cooperates with the curved surface matching design of the shaping head and the forming groove, realizes the synchronous precision control of the cutting edge and the shaping surface, through the setting of the pressing device, the cutting and shaping are combined during the processing of the forming device, the single workpiece processing time is shortened from 25 seconds to 12 seconds, the process of material transfer is reduced, and the production efficiency of the forming device and the yield of the workpiece are improved.

[0027] 2、In the present application, by setting up the dynamic clamping device composed of sleeve, guide groove, protrusion, clamping frame, guide frame, slider and spring, a whole-process stable system of "pre-clamping-flexible accommodation-precise resetting" in the cutting process is constructed: when the upper die moves down, the clamping frame pushes the sleeve first to contact the strip-shaped plate before the die, using the initial locking structure of the guide groove and the protrusion to form a pre-clamping force of 6-8N, cooperating with the lower die to realize the axial positioning of the material; after the clamping frame is in place, the guide frame is inserted into the guide groove to drive the sleeve to rotate, so that the protrusion is separated from the constraint groove, allowing the sleeve to move down in the empty stroke under the die pushing force, avoiding rigid interference; the innovation of the device lies in the two-stage action mechanism of "clamping-accommodation": in the pre-clamping stage, the elastic contact surface of the clamping frame forms a 15-20mm² bonding area with the plate, which suppresses the vibration displacement during cutting; in the accommodation stage, the trajectory of the guide groove cooperates with the spring buffer of the slider, so that the sleeve releases the vertical movement freedom of the clamping frame in rotation, ensuring that the cutting force of the upper die is not affected by the clamping structure; when resetting, the spring drives the slider to accurately return along the rotating groove, so that the guide groove and the protrusion are re-locked, ensuring the repeat positioning accuracy of subsequent clamping; by setting the clamping device, the equipment can clamp the material to be processed synchronously during cutting, thereby ensuring the stability of the material during processing and improving the processing accuracy.

The anti-skid pattern design on the surface of the chain and the limiting groove of the bearing frame ensure the stable conveying of the workpiece, avoid the processing interruption caused by workpiece accumulation;Compared with the traditional manual workpiece taking mode, the system improves the equipment processing efficiency by more than 35%, reduces 70% of manual intervention, and is especially suitable for batch automatic production of disc-shaped and plate-shaped parts, and ensures the high smoothness of the processing flow and the stability of the production rhythm through the integrated design of "discharging-conveying".
