DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] The present application embodiment provides a raw material feeding and discharging device, such as Figure 1 and Figure 2As shown, it includes a carrier plate 1, which is provided with two channel grooves 11 arranged along the length direction and passing through the front end of the carrier plate 1. The number of channel grooves 11 can also be set according to actual usage and the structure of the heating furnace. The inner side wall of the channel groove 11 is provided with a matching groove 13 along the length direction. Guide blocks 24 arranged along the length direction of the carrier plate 1 are provided at both ends of the tray 2. The guide blocks 24 are slidably fitted in the matching groove 13. Four trays 2 are installed in each channel groove 11. A clamping mechanism 21 is provided on the tray 2 for clamping raw materials, wherein the raw materials The material is specifically a ring-shaped metal workpiece or a shaft-type metal workpiece with a flange at one end. When there are multiple trays 2 in a channel groove 11, the multiple trays 2 can be detachably connected. Docking blocks 12 are provided on both sides of the front end of the supporting plate 1. A V-shaped groove is provided vertically on the front end surface of the docking block 12. A pair of matching rods for docking with the docking block 12 are vertically provided at the inlet and outlet of the heating furnace. The supporting plate 1 is supported on top of a base plate 5 by five brackets 4. Rollers 3 are provided at the four corners of the lower part of the base plate 5, and a hand push rack 14 is provided at the rear end of the supporting plate 1.

[0018] When in use, first put a batch of annular metal workpieces or shaft-type metal workpieces with a flange at one end into the clamping mechanism 21 on the tray 2, and use the clamping mechanism 21 to fix the raw material workpiece to be heated to avoid the problem of the workpiece slipping out of the tray due to inertia when transporting the workpiece; after the raw material workpiece is installed in the clamping mechanism 21 on each tray 2, connect each tray in turn, push the hand push frame 14, align the opening of the V-shaped groove on the two docking blocks 12 at the front end of the channel groove 1 with the corresponding matching rods at the inlet and outlet of the heating furnace, and continue to push the carrier plate 1 toward the inlet and outlet of the heating furnace. When the two inner walls of the V-shaped groove on the docking block 12 are simultaneously aligned with the matching rod When the surfaces are tangent, the front end of the carrier plate 1 is docked with the inlet and outlet of the heating furnace, that is, the channel groove 11 is connected to the inlet and outlet of the heating furnace, and the matching groove 13 is at the same height as the material rack for carrying the tray 2 arranged parallel to the heating furnace; the tray 2 located at the rear end of the channel groove 11 is pushed, so that the trays 2 in the channel groove 11 are pushed into the material rack in the heating furnace in sequence; after the workpiece is heated, the tray 2 near the inlet and outlet of the heating furnace is pulled. Since the trays 2 are connected to each other, the other trays 2 on the material rack are taken out in sequence and sent back into the channel groove 11 in sequence, and then the trays are separated to wait for the workpieces to be transported in batches to the next process. Through the detachable setting between the trays 2, and under the action of the docking block 12 and the matching rod, the function of raw material workpieces entering and exiting the heating furnace in batches is realized, which optimizes the feeding and unloading process of raw material workpieces in the heating process and improves production efficiency.

[0019] Specifically, such as Figure 1 and 2As shown, the clamping mechanism 21 includes a pair of clamping seats 211 arranged on the surface of the tray 2, and a pair of telescopic rods 212 are vertically inserted on the opposite surfaces of the pair of clamping seats 211. The telescopic rods 212 are arranged to move along their own axes, and the distal ends of the telescopic rods 212 are connected to V-shaped blocks 213. The opening of the V-shaped block 213 faces the clamping seat 211 on the opposite side. The upper end of the V-shaped block 213 is provided with a guide block 215. The guide block 215 includes two inclined blocks 216 respectively arranged on both sides of the upper end of the V-shaped block, and the inclined surface of the inclined block 216 faces the upper part of the clamping seat 211 on the opposite side. A clamping spring 214 is sleeved on the telescopic rod 212 between the V-shaped block 213 and the clamping seat 211. When the clamping spring 214 is in a natural state, the distance between the two V-shaped blocks 213 is less than the outer diameter of the annular metal workpiece or the maximum outer diameter of the shaft-type metal workpiece with a flange at one end. During application, if it is a circular metal workpiece, the workpiece is placed between the two V-shaped blocks 213 in a posture parallel to the tray 2 and perpendicular to the tray 2. During the placement of the workpiece, the edge of the outer ring of the workpiece is in contact with the inclined surfaces of the four inclined blocks 216, and moves downward along the inclined surfaces, thereby resisting the elasticity of the clamping spring 214 to push the two V-shaped blocks 213 toward each other. When the workpiece moves downward until it contacts the bottom surface of the tray 2, the two V-shaped blocks 213 clamp the workpiece under the action of the clamping spring 214; if it is a shaft-type metal workpiece with a flange-shaped end, the flange-shaped end is facing downward, and placed between the two V-shaped blocks 213 in a posture parallel to the tray 2 and perpendicular to the tray 2. The guiding and clamping process is consistent with that of the circular metal workpiece. Through the structural design of the clamping mechanism 21, it can be adapted to the clamping of a variety of circular or shaft-type workpieces, thereby improving the applicability of the clamping mechanism 21. At the same time, the pallet 2 also has a certain applicability. In combination with the clamping mechanism 21, the pallet 2 can be used as a carrier for the flow of raw materials in various processing steps, thereby optimizing the transfer process of the raw material workpieces and improving the processing efficiency of the production line. The clamping effect of the clamping mechanism 21 is reliable, thereby avoiding the problem of the raw material workpieces sliding off the pallet during transfer, thereby improving the safety of production and processing.

[0020] Specifically, such as Figure 2 and Figure 3 As shown, a first support plate 22 is provided on one side of the pallet 2, and a second support plate 23 is provided on the other side. Locking holes 221 are provided through both the first support plate 22 and the second support plate 23. The first support plates 22 and the second support plates 23 on either side of two adjacent pallets 2 are vertically staggered. During use, the two adjacent pallets 2 are brought together until the locking holes 221 on the first support plate 22 and the second support plate 23 between the two adjacent pallets 2 overlap. The locking pin 222 is then inserted into the two overlapping locking holes 221 to connect the two pallets 2. The pallets 2 are separated by removing the locking pin 222. The use of locking holes and locking pins simplifies the connection between the pallets 2, facilitates the disassembly and maintenance of the pallets 2, and thus improves production efficiency.

[0021] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
