Description

Technical Field

[0001] The invention relates to the technical field of casting, in particular to a casting plant for producing castings. Background Art

[0002] In order to improve the intelligence of the factory, reduce heavy physical labor and be green and environmentally friendly, the current intelligent foundry factory has replaced the original crane of the traditional sand casting foundry with a truss robot for lifting and flipping molds and castings, replaced the flat car with a navigation car such as AGV or RGV, and replaced the core making and molding equipment such as sand mixers and core shooters with sand mold additive manufacturing equipment, realizing the intelligent transformation of the foundry. In this transformation, due to the structural limitations of the truss robot, the following problems exist in the sand core grabbing and transportation process:

[0003] 1) The printing layout of sand mold additive manufacturing equipment is greatly restricted by the truss grabbing, resulting in a low printing layout rate;

[0004] 2) Low logistics efficiency: such as slow box clearing speed, frequent sand core placement, etc.;

[0005] 3) High equipment investment;

[0006] 4) High equipment operating costs: The truss system, paint supply system, and microwave drying system operate unstably and have a high failure rate. Summary of the invention

[0007] In view of the high operating cost and poor operation continuity caused by the use of truss robots to transfer sand cores in the molding process of the above-mentioned intelligent casting factory, it is necessary to propose a lifting line based on a hoist and a foundry equipped with the lifting line. The hoist is used as a lifting device, which avoids the problem of setting a grabbing structure on the sand core when the sampling truss robot grabs the sand core, thereby improving the sand cleaning efficiency of the core making process and the surface drying efficiency of the sand core.

[0008] A hoisting line based on a hoist includes a guiding mechanism and a clamping mechanism, wherein the guiding mechanism is the traveling mechanism of the hoisting line, and the clamping mechanism is used to grab objects, and the guiding mechanism and the clamping mechanism cooperate with each other to transfer the objects to a designated position; the guiding mechanism includes a continuously extending guide rail and a hoist, and the clamping mechanism includes a clamping piece and a locking piece, and the clamping mechanism is arranged below the hoist, and the hoist drives the clamping mechanism to run along the continuously extending guide rail, thereby realizing the transfer of the clamped objects and various operations.

[0009] Furthermore, the continuously extending guide rail is arranged in the molding process of the foundry to realize the transportation and related operations of the sand core in the molding process.

[0010] Furthermore, a plurality of the hoists are arranged on the continuously extending guide rail to form a hoisting line based on the hoists to realize the transportation of objects.

[0011] Furthermore, the clamping member is a claw symmetrically arranged on the locking member, and the two opposite claws can reciprocate along the locking member to achieve the clamping effect on the object.

[0012] Furthermore, the locking member includes a driving motor, a beam, and a lead screw. The lead screw is arranged on the beam in parallel along the length direction of the beam. The driving motor is arranged at one end of the beam, and the driving motor is connected to the lead screw to drive the lead screw to rotate; the clamping member is arranged on the lead screw, and the clamping member reciprocates along the lead screw.

[0013] As an optimization of the present technical solution, the hoisting line based on the hoisting hoist can be arranged in the molding process of the foundry to grab, transport, clean sand, and apply sand cores.

[0014] As an optimization of the technical solution, a foundry, including the hoisting line based on the hoisting hoist, realizes efficient transportation, efficient sand cleaning and efficient application of sand cores in the molding process.

[0015] Furthermore, the operation process of the sand core in the molding process of the foundry includes:

[0016] The additive manufacturing equipment prints the sand core, and transfers the printed sand core together with the work box to the work box cache line, and the empty work box of the cache line is transferred to the additive manufacturing equipment;

[0017] The working box with the sand core is transferred from the buffer line to the sand cleaning station, where the sand core is leaked out of the working box and then transferred to the mobile cart;

[0018] The mobile trolley carries the sand core to the lower part of the lifting line based on the hoist, and the hoist transfers the sand core to the automatic sand cleaning room to automatically clean the sand core;

[0019] After the automatic sand cleaning is completed, the hoist carries the sand core to the curing chamber to cure the sand core;

[0020] After the curing is completed, the sand core is carried by the hoist to the manual sand cleaning room, where the sand core is manually cleaned by the operator and a chiller is placed on the sand core;

[0021] The hoist then carries the sand core to the coating room to apply high temperature protection to the sand core; preferably, additional coating is applied to the sand core to ensure that the surface of the sand core or the surface of the cavity is evenly covered with coating;

[0022] The hoisting hoist then carries the sand core to the drying device to dry the surface of the sand core; preferably, the drying device is a through-type surface drying furnace, and the hoisting line based on the hoisting hoist passes through the through-type surface drying furnace, so that the sand core can be dried in the process of passing through the drying device;

[0023] The sand core is then carried by the hoist to the stereoscopic warehouse for storage for later use.

[0024] The above technical solutions realize the continuity of the production process of the molding process, improve the working efficiency and shorten the production cycle.

[0025] The beneficial effects of the technical solution of the present invention are as follows: by adopting a hoisting line based on a hoisting hoist to replace the existing truss robot, not only the construction cost of the factory is saved, but also the production efficiency of the molding process is improved, and the continuous production of the molding process is realized.

The provision of the clamping member 2 reduces the number of invalid grabbing times of the sand core 6, achieves a successful grabbing once, and improves the efficiency and quality of the sand core 6 coating.

[0038] As a further supplement to this embodiment, the driving component 301 includes a motor, a first gear, a second gear and a rotating shaft.

[0041] Another embodiment is a foundry, in which the lifting line based on the hoist 1 and the through-type drying equipment are set in the molding process of the foundry, and the spatial height of the continuously extended guide rail 5 of the guiding mechanism is higher than the sand cleaning room, curing room, coating room, drying equipment and three-dimensional warehouse and other operating equipment, thereby realizing the continuity of production in the molding process and improving the production efficiency and production quality of the molding process.

[0044] The additive manufacturing device prints the sand core 6, and transfers the printed sand core 6 together with the work box to the work box cache line, and the empty work box of the cache line is transferred to the additive manufacturing device;

[0050] The hoisting hoist 1 then carries the sand core 6 to the drying device to dry the surface of the sand core 6; preferably, the drying device is a through-type surface drying furnace, and the hoisting line based on the hoisting hoist 1 passes through the through-type surface drying furnace, so that the sand core 6 can be dried in the process of passing through the drying device;

[0051] The sand core 6 is then carried by the hoist 1 to the stereoscopic warehouse, where it is stored for later use.

[0052] As a further supplement to this embodiment, the mobile trolley carries the sand core 6 to the lower part of the lifting line based on the hoist 1, and the hoist 1 transfers the sand core 6 to the automatic sand cleaning room. The specific clamping process includes:

[0056] The driving assembly drives the lead screw to rotate, and the lead screw drives the clamping mechanism to clamp the sand core 6;

[0057] After clamping in place, the mobile trolley descends a certain distance and then drives away;

[0058] By repeating the following operations, a plurality of sand cores 6 can be hung on the lifting line, and transported by the lifting line to the sand cleaning room, curing room, coating room, drying equipment, stereoscopic warehouse and other working positions to achieve the processing of the sand cores 6.
