when the hot forming product rack provided by the embodiment of the invention is used for loading blank parts, the accommodating cylinder is used for directly accommodating the blank parts. When the blank piece is placed in the accommodating cavity of the accommodating cylinder, the head of the blank piece is placed upwards, at the moment, the first bulge part of the accommodating cylinder directly supports the blank piece from the bottom, and the second bulge part of the accommodating cylinder surrounds and limits the blank piece from the periphery.

Wherein, first uplift is when forming the support to the stock spare, still lets leave the clearance between the bottom of stock spare and the bottom of a holding section of thick bamboo to also can fully be heated in the bottom of hot forming's in-process stock spare, more do benefit to the volatile substance and distribute out smoothly from its low side, so that hot forming goes on smoothly. The second bulge limits the blank from the periphery, so that on one hand, the stability of the blank is greatly improved, the blank is prevented from being damaged due to random shaking in the carrying and transferring processes, and the protection effect on the blank is effectively improved; on the other hand, the second uplift portion has still flowed sufficient space for between the lateral wall of an accommodation section of thick bamboo and the stock spare, not only is convenient for make the stock spare fully heated at thermoforming's in-process, more does benefit to the volatile substance and volatilizes out from the clearance between an accommodation section of thick bamboo and the stock spare, promotes thermoforming's going on smoothly, improves the heat preservation effect.

It should be noted that when the thermoforming step is performed, the volatile in the blank will escape, and whether there is enough space around the blank determines whether the volatile can escape sufficiently and whether the thermoforming effect is desirable. After entering into the heat preservation stage, along with the volatile substance effluvium, the volatile substance concentration around the blank begins to increase, owing to the design of the first uplift portion that the holding section of thick bamboo is peculiar and the second uplift portion, has guaranteed to have sufficient space between blank material and the holding section of thick bamboo, and this is favorable to the volatile substance to effluvium smoothly. In the volatile matter dissipation process, the volatile matter can be followed the axial of an holding section of thick bamboo on the one hand and escaped in the oral area of an accommodation section of thick bamboo in the clearance of an accommodation section of thick bamboo lateral wall and embryo material spare, also can directly escape through the air vent of second uplift portion, and this has apparent effect to the volatile matter concentration that reduces fast around the embryo material spare to promote remaining volatile matter in the embryo material spare to accelerate to volatilize, and then accelerate the shaping efficiency in the heat preservation stage.

On the other hand, the air vent of second uplift has also improved the gas permeability and the diathermy nature in holding chamber greatly, and this helps the blank spare abundant, even, in time to be heated, and when the heat was transmitted through the gas in the thermoforming equipment, the hot gas flow also can get into a holding section of thick bamboo through the air vent and come to carry out the hot scour to the holding chamber, and this not only has accelerated the heating efficiency and the degree of consistency of being heated of blank spare, has also further promoted the discharge of volatile substance.

Examples

Referring to fig. 1 to 4, the present embodiment provides a hot forming product rack 1000 for producing hard alloy. The thermoformed product holder 1000 includes: a plate body 100 and a receiving cylinder 200.

The containing tubes 200 are perpendicular to the plate surface of the plate body 100 and embedded in the plate body 100, and the containing tubes 200 are distributed in an array along the plate surface of the plate body 100. The receiving cylinder 200 has a receiving cavity 210 for receiving a turning tool or a milling cutter, the bottom wall of the receiving cylinder 200 has a first protrusion 220 formed by being recessed from the outside toward the inside, and the sidewall of the receiving cylinder 200 has a second protrusion 230 formed by being recessed from the outside toward the inside. The second protrusions 230 are uniformly spaced in both the circumferential direction and the axial direction of the receiving tube 200. The second raised part 230 is opened with a vent hole 231.

The plate body 100 is provided with two opposite side edges with ear portions 110 for lifting, and one side plate surface of the plate body 100 is further provided with a support leg 120. The end of the leg 120 has a bent portion 121 parallel to the panel surface of the panel body 100, and the top wall of the ear 110 is opened with a receiving groove 111 for receiving the bent portion 121 of the leg 120 of another thermo-formed product shelf 1000. The side wall of the ear 110 away from the plate body 100 is provided with a sliding groove extending towards the plate body 100, the sliding groove is slidably matched with a sliding part 114, the outer end of the sliding part 114 is hinged with a handle 115, and the handle 115 is provided with a pressing block 116 for pressing the bending part 121 against the accommodating groove 111. The mouth of the sliding groove has an extension plate 118 disposed parallel to the plate body 100.

The slider 114 has a first sliding stop and a second sliding stop. When the sliding member 114 is located at the first sliding dead point, as shown in fig. 4, the sliding member 114 is completely accommodated in the sliding groove, the extending plate 118 is attached to the handle 115 and prevents the handle 115 from rotating, and the pressing plate presses the bending portion 121 against the accommodating groove 111. When it is necessary to slide the slider 114 from the first sliding stop point to the second sliding stop point, the handle 115 is simply pulled, as shown in fig. 5. When the sliding member 114 is located at the second sliding stop point, as shown in fig. 6, the sliding member 114 slides out from the sliding groove portion, and the handle 115 is separated from the extension plate 118 so that the extension plate 118 releases the restriction of the handle 115, thereby releasing the locking of the abutting block 116, and further releasing the bent portion 121 from the accommodating groove 111.

The thermoformed product holder 1000 is well suited for holding elongated stock material, such as milling, turning, drilling, etc. When used for loading a blank, the receiving cylinder 200 is used for directly receiving the blank. When the blank is placed in the accommodating cavity 210 of the accommodating tube 200, the head of the blank is placed upward, and at this time, the first bulge portion 220 of the accommodating tube 200 directly supports the blank from the bottom, and the second bulge portion 230 of the accommodating tube 200 surrounds and limits the blank from the periphery.

Wherein, first uplift 220 still leaves the clearance between the bottom of blank piece and the bottom of holding a section of thick bamboo 200 when forming the support to the blank piece to the bottom of blank piece also can be heated fully at thermoforming in-process, more does benefit to the volatile substance and distributes out smoothly from its low side, so that thermoforming goes on smoothly. The second bulge part 230 limits the blank from the periphery, so that on one hand, the stability of the blank is greatly improved, the blank is prevented from being damaged due to random shaking in the carrying and transferring processes, and the protection effect on the blank is effectively improved; on the other hand, the second raised part 230 also provides a sufficient gap between the sidewall of the accommodating cylinder 200 and the blank, so that the blank is heated sufficiently in the thermal forming process, volatiles are volatilized from the gap between the accommodating cylinder 200 and the blank, the thermal forming is promoted to be performed smoothly, and the heat preservation effect is improved.

It should be noted that when the thermoforming step is performed, the volatile in the blank will escape, and whether there is enough space around the blank determines whether the volatile can escape sufficiently and whether the thermoforming effect is desirable. After the heat preservation stage, the concentration of the volatile matter around the blank starts to increase as the volatile matter escapes, and due to the design of the first raised part 220 and the second raised part 230 specific to the containing cylinder 200, it is ensured that there is a sufficient gap between the blank and the containing cylinder 200, which is beneficial to the volatile matter to escape smoothly. In the volatile matter dissipation process, the volatile matter can escape from the gap between the sidewall of the accommodating barrel 200 and the blank material piece through the mouth of the accommodating barrel 200 in the axial direction of the accommodating barrel 200, and can also directly escape through the vent hole 231 of the second raised part 230, which has a significant effect on rapidly reducing the concentration of the volatile matter around the blank material piece, so that the volatile matter remaining in the blank material piece is accelerated to volatilize, and the forming efficiency in the heat preservation stage is accelerated.

On the other hand, the ventilation hole 231 of the second bump 230 also greatly improves the air permeability and the heat permeability of the accommodating cavity 210, which helps the blank to be fully, uniformly and timely heated, when the heat is transferred through the gas in the thermal forming equipment, the hot gas flow can also enter the accommodating cylinder 200 through the ventilation hole 231 to carry out hot washing on the accommodating cavity 210, which not only accelerates the heating efficiency and the heating uniformity of the blank, but also further promotes the discharge of volatile matters.

After entering the heat preservation stage through the preheating stage, the dissipation rate of volatile matters in the blank material part tends to be regular, and the arrangement mode of the accommodating cylinder 200 is favorable for the volatile matters to stably and timely leave the accommodating cylinder 200, so that the forming rate of the blank material part is promoted to be improved.

The inventor of the present application has found that: for the existing product shelf, if the product shelf pursues effective protection of the blank, the blank can be seriously shielded and covered under general conditions, which is very unfavorable for the blank to be fully heated, and in addition, the blank is excessively covered and shielded, the surrounding space is insufficient, and the volatile matter is also unfavorable for dissipation, so that the volatilization efficiency which can be exerted slowly can be greatly reduced, and the forming speed can be reduced. However, if the existing product shelf tends to improve the hot forming efficiency, the blank is not protected in place, the blank is exposed in a high proportion, and the blank is easily scratched in the process of carrying and transferring and is even directly knocked down by an operator. The inventor of the present application has well solved the above-mentioned problem with thermoforming product frame 1000, when guaranteeing to have fine guard action to the stock spare, has still improved the shaping efficiency of stock spare greatly.

In addition, the inventors of the present application have also found through research that: the loading capacity of the conventional product frame is small when blank pieces are loaded, the product amount in a single thermal forming process is small, and the resource utilization rate is low. The existing product racks also have a large loading capacity in part, for example, some lathe tools increase the loading capacity by placing lathe tools densely in the grooves on the surface of the bearing plate at one time, but have a series of defects. On one hand, the fixing and protecting effects on the blank piece are poor, the blank piece is easy to drop or scratch in the carrying process, on the other hand, the blank piece is too dense, all parts are heated unevenly in the thermal forming process, the time required for the whole blank piece to reach uniform temperature is longer, and the volatile matter is not beneficial to fast dissipating, and the thermal forming efficiency is directly slowed down.

The utility model provides a hot forming product frame 1000's a holding section of thick bamboo 200 perpendicular to plate body 100 sets up, and its density of arranging can be very high, and first uplift 220 and second uplift 230 mutually support simultaneously, make on the one hand and left great space between blank material spare and a holding section of thick bamboo 200, and on the other hand has also made a large amount of depressed areas appear in the outside of a holding section of thick bamboo 200, and then has further increased the space between a holding section of thick bamboo 200. That is, the thermoformed product rack 1000 not only has a large loading capacity of blank material, but also reserves enough space for heat transfer and volatile dissipation, and the utilization rate of the thermoformed product rack 1000 to the effective space is obviously improved.

The thermoforming product frame 1000 utilizes the matching structure of the support legs 120 and the ear parts 110, and can realize overlapping connection of a plurality of thermoforming product frames 1000, so that a thermoforming product frame group is formed, the loading capacity of the thermoforming product frame group is further improved, the formed thermoforming product frame group is more convenient to place blank pieces into thermoforming equipment at one time, and repeated operation and workload in the placing process are reduced.

When the sliding member 114 is located at the first sliding stop point, as shown in fig. 4, the handle 115 is locked by the extension plate 118, so that the thermoforming product racks 1000 are stably connected with each other, and the thermoforming product rack assembly is not disassembled because a certain thermoforming product rack 1000 is used as a force application point, so that the overall stability of the thermoforming product rack assembly is ensured. When the thermoformed product rack assembly needs to be disassembled (for example, when the thermoformed product rack assembly needs to be taken out after thermoforming), the handle 115 is pulled to slide the sliding member 114 toward the outside of the ear 110, as shown in fig. 5, the sliding member 114 can be pulled from the first sliding stop point to the second sliding stop point, so as to release the connection relationship between the thermoformed product racks 1000. The whole assembling and disassembling process is very convenient, and the production efficiency is further improved.

In general, the hot forming product rack 1000 has a large loading capacity, and can effectively protect the cemented carbide blank from damaging the integrity of the blank during the transportation and transfer. In the process of hot forming, the forming efficiency can be effectively improved, and the blanks can be fully and uniformly formed. The thermoformed product holder 1000 is well suited for use with blank material for carrying milling and turning tools.

In the present embodiment, please refer to fig. 1 to 6, the plate body 100 is a rectangular plate, the accommodating cylinder 200 is a cylinder shape as a whole and is disposed perpendicular to the plate surface of the plate body 100, and the accommodating cylinders 200 are distributed on the plate body 100 in an orthogonal array. The ear 110 is a long strip and extends along the side of the plate body 100, the cross section of the ear 110 pair is rectangular, and the top wall of the ear 110 and the upper plate surface of the plate body 100 are located on the same plane.

The sliding groove is perpendicular to the side wall of the ear 110 and extends towards the plate body 100, the sliding groove comprises an expanding section 112 and a reducing section 113 which are communicated, the expanding section 112 and the reducing section 113 are both cylindrical, the expanding section 112 is positioned on one side of the reducing section 113, which is far away from the notch of the sliding groove, and the central axes of the expanding section 112 and the reducing section 113 are both arranged parallel to the plate surface of the plate body 100. The slider 114 has a cylindrical rod shape, the outer diameter of the slider 114 is slightly smaller than the inner diameter of the reduced diameter section 113, and the inner end of the slider 114 has a stopper 114a for preventing the slider 114 from coming out.

The sliding grooves are arranged in parallel at intervals and distributed on the side wall of the ear 110 along the extending direction of the ear 110, and the central axes of the sliding grooves are located on the same plane parallel to the plate surface of the plate body 100.

The handle 115 is in the shape of a long strip, the handle 115 extends along the side of the board body 100, the sliding members 114 of the plurality of sliding grooves are hinged with the handle 115, and the rotation axis of the handle 115 is parallel to the board body 100 and perpendicular to the central axis of the sliding groove. The pressing block 116 and the handle 115 are fixedly connected by a connecting column 117, the connecting column 117 is perpendicular to the handle 115, and the pressing block 116 is parallel to the handle 115 and extends from the connecting column 117 to one side of the plate body 100. The abutting faces of both the extension panel 118 and the handle 115 are smoothed.

The extension plate 118 is also in the form of a long strip, and the extension plate 118 is located on one side of the ear portion 110 away from the plate body 100 and extends along the extending direction of the two portions. The upper plate surface of the extension plate 118 is tangent to the circumference corresponding to the inner wall of the reduced diameter section 113 of the sliding groove, and the tangent point is located at the lowest point of the inner wall of the reduced diameter section 113. In this embodiment, the thickness of the handle 115 is equal to the diameter of the slider 114. The length of the handle 115 is greater than the length of the extension plate 118 in the axial direction of the slide groove.

In addition, the legs 120 are also disposed perpendicular to the plate surface of the plate body 100, and the bent portions 121 are parallel to the plate surface of the plate body 100, that is, the bent portions 121 are disposed perpendicular to the legs 120. The receiving groove 111 is slightly larger than the bending portion 121, and the depth of the receiving groove 111 is equal to the thickness of the bending portion 121.

When the sliding member 114 is located at the first sliding stop point, the handle 115 is attached to the extending plate 118, a portion of the handle 115 is still exposed outside the extending plate 118, the connecting post 117 is attached to a sidewall of the ear 110 away from the plate 100, and the pressing block 116 is attached to an upper surface of the ear 110.

Through above design, promoted the locking effect of support piece 116 to kink 121 greatly, promoted laminating effect and stability between each part simultaneously greatly, not only convenient and practical also lets the thermoforming product frame group that constitutes by thermoforming product frame 1000 have higher stability.

Further, the upper plate surface of the plate body 100 has a recessed area 130, a bottom wall of the recessed area 130 is disposed parallel to the upper plate surface of the plate body 100, and a mouth of the accommodating barrel 200 is flush with the bottom wall of the recessed area 130. Through this design, can utilize depressed area 130 to make the abdication, reserve sufficient space for the head of embryo material spare (for example the head of lathe tool, milling cutter and drill bit), avoid the length of exposing of the head of embryo material spare too big and increase the fish tail probability. When a plurality of thermoforming product racks are combined into a thermoforming product rack group, a sufficient gap is reserved between two adjacent thermoforming product racks 1000, and meanwhile, the mounting positions of all the accommodating cylinders 200 are integrally moved down, so that the probability of head damage of the blank is greatly reduced.

The first bump 220 is hemispherical and the second bump 230 is semi-ellipsoidal. On the outer wall of the receiving cylinder 200, the recess formed at the first protrusion 220 is also formed in a semi-spherical shape, and the recess formed at the second protrusion 230 is formed in a semi-ellipsoidal shape. The number of the vent holes 231 is two, and the two vent holes 231 are distributed at two ends of the second raised part 230 along the major axis direction of the ellipsoid corresponding to the second raised part 230. By the design, the integral smoothness of the side wall of the accommodating cylinder 200 can be greatly improved, and the air movement is facilitated. In the heat preservation stage, the gas phase in the thermoforming equipment is in a state of weak overall fluidity (except for molecular heat movement) for most of time, but under the action of the vent hole 231, a local "coanda effect" is very likely to occur, which is beneficial to gas exchange of the gas phase inside and outside the accommodating cylinder 200 through the vent hole 231, as shown in fig. 7, so that the overall flowing capacity of the gas phase in the whole thermoforming equipment is improved, and the heating effect and the volatile substance dissipation rate are further optimized.

The major axis of the ellipsoid corresponding to the second protrusion 230 is disposed along the axis of the accommodating barrel 200, and the central axis of the vent hole 231 passes through the center of the ellipsoid corresponding to the second protrusion 230. The two ventilation holes 231 of each second raised part 230 are symmetrically distributed along the plane of the minor axis of the ellipsoid corresponding to the second raised part 230, and the included angle between the central axes of the two ventilation holes 231 of each second raised part 230 is 60-120 °. In the present embodiment, the angle between the central axes of the two ventilation holes 231 of each second raised part 230 is 70 °.

Through above design, the volatile substance that more does benefit to in the holding section of thick bamboo 200 on the one hand passes through vent 231 loss and comes out, and on the other hand also more is favorable to outside high heat gas to get into a holding section of thick bamboo 200 to make the stock spare can be heated fast, uniformly in the stage of rising the temperature, and make the stock spare can reach whole samming faster after getting into the heat preservation stage, improve the heat preservation effect, simultaneously, also help the quick natural cooling of formed part in the cooling stage. In addition, the structural optimization is more convenient for the flow of weather, and the occurrence probability of local 'coanda effect' is further improved.
