Description

Technical Field

[0001] The utility model belongs to the technical field of electroforming process of metal matrix composite materials, in particular to a novel non-electroforming area pre-processing device suitable for electroforming process. Background Art

[0002] When producing a workpiece with a cylindrical upper part and a trumpet-shaped lower part, it is necessary to drip wax on the grooves evenly distributed on the surface. In the prior art, the operator holds a wax strip, melts the wax strip by heating with a heating tube, and then drips the wax liquid on the groove of the workpiece to fill the gap with wax. Although the process is simple and easy to operate, it has the following disadvantages:

[0003] 1. The wax strips will produce harmful gases during the heating process, and long-term contact and inhalation of operators will cause damage to the body;

[0004] 2. Because the grooves on the workpiece surface are densely distributed and the gaps are small, the corners are difficult to process, which increases the scrap rate and makes it impossible to ensure the continuous output of qualified products;

[0005] 3. During the processing, the melting time of the wax strips, the dripping speed and flow rate of the wax liquid, the physical condition of the operator, and the operating experience are different, so the consistency of the product cannot be guaranteed. If there are many residual products, the efficiency will continue to decrease and the cost will increase during the production process with high labor intensity. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a novel non-electroforming area pre-treatment device suitable for the electroforming process, which can replace the manual wax dripping operation and avoid the operator's long-term contact with the gas produced when the wax liquid melts. Through the mutual linkage of the machines, the wax liquid can cover each groove, and the wax dripping thickness is guaranteed to be consistent, thereby ensuring the consistency of product quality.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is: a new non-electroforming area pre-treatment device suitable for electroforming process, including a wax dripping mechanism and a driving mechanism, wherein the wax dripping mechanism is linked with the driving mechanism through a six-axis mechanical arm;

[0008] The wax dripping mechanism comprises a drip irrigation part connected to the inner cavity of the conveying part, and the wax liquid drips from the outlet of the drip irrigation part to the groove of the workpiece by gravity. A guide rod is retractable in the drip irrigation part, and the guide rod is used to block the outlet of the drip irrigation part;

[0009] The driving mechanism comprises a swing frame which can swing forward and backward and a clamping assembly which can rotate at the front end of the swing frame, and the workpiece is fixed on the clamping assembly.

[0010] Furthermore, the drip irrigation part includes a drip irrigation pipe and a drip irrigation head connected to the lower end, and a blocking needle matching the pinhole at the lower end of the drip irrigation head is arranged at the lower end of the guide rod.

[0011] Furthermore, the wax dripping mechanism includes a heating tank communicated with the inner cavity of the conveying part, which is used for storing and heating the wax blocks.

[0012] Furthermore, a gap is left between the guide rod and the inner cavity of the drip irrigation part for the wax liquid to pass through, and the inner cavity at the outlet of the drip irrigation head is in an inverted cone shape.

[0013] Furthermore, the clamping assembly includes a support shaft and a clamping plate A arranged on the inner side thereof, and the clamping plate B is sleeved on the support shaft and fixed by a stopper.

[0014] Furthermore, it comprises a bracket, the six-axis robot arm is arranged on the bracket, and the bracket is provided with a mounting groove for placing the driving mechanism.

[0015] Furthermore, a fixing frame is provided at the lower end of the mounting groove, and the swing frame can rotate between the fixing frames.

[0016] Furthermore, the wax dripping mechanism is connected to the end of the six-axis robot arm through a connecting frame, and a locking portion that can control the opening and closing of the heating tank cover is provided on the connecting frame.

[0017] Furthermore, a dust cover capable of covering the mounting groove is arranged on the bracket.

[0018] The advantages and positive effects of the utility model are:

[0019] 1. The above technical solution replaces the existing manual wax dripping operation, effectively avoiding the operator's long-term contact with the gas generated when the wax liquid melts, and the wax block is heated in the heating tank, so that the harmful gas is not easy to leak out, thereby ensuring the safety of personnel.

[0020] 2. The wax dripping mechanism and the driving mechanism are linked by a six-axis robotic arm and can be controlled by a PLC program to realize automated production. The six-axis robotic arm operates flexibly, and the driving mechanism can drive the workpiece to swing back and forth and rotate axially, so that the pinhole of the wax dripping head accurately corresponds to the groove at each position. The extension and retraction of the guide rod in the wax dripping mechanism can block the passage of the wax liquid in time, so that the wax liquid flows evenly into the groove, ensuring the uniform thickness of the wax liquid in the groove, so that qualified products are continuously produced, efficiency is improved, and consistency of product quality is guaranteed.

In order to adapt to the drip flow rate of different requirements, it can be achieved by replacing the drip irrigation head 42. In order to facilitate the collection of the wax liquid, the inner cavity at the outlet of the drip irrigation head 42 is inverted cone shape;

[0038] A blocking needle matching the pinhole of the drip irrigation head 42 is arranged at the lower end of the guide rod 5, and the passage of the wax liquid is controlled by the cooperation between the blocking needle and the pinhole.
