Detailed Description
The present application will be further described with reference to the following specific embodiments, and it should be noted that, on the premise of no conflict, new embodiments may be formed by any combination of the embodiments or technical features described below.
In the description of the present application, it should be noted that, for the azimuth words such as terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the azimuth and positional relationships are based on the azimuth or positional relationships shown in the drawings, it is merely for convenience of describing the present application and simplifying the description, and it is not to be construed as limiting the specific scope of protection of the present application that the device or element referred to must have a specific azimuth configuration and operation.
It should be noted that the terms "first," "second," and the like in the description and in the claims are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.
The terms "comprises" and "comprising," along with any variations thereof, in the description and claims, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1 to 4, the blank hoisting structure according to a preferred embodiment of the present application includes a template 1 and a hoisting auxiliary block 2, the hoisting auxiliary block 2 is separately provided and adapted to be fixedly connected to the template 1, and the hoisting structure further includes a hoist ring screw hole 3 penetrating the template 1 and extending into the hoisting auxiliary block 2, wherein the hoist ring screw hole 3 is adapted to be screwed with a hoist ring (the hoist ring is a standard component, and is not shown in the drawings). Compared with the milled boss, the split arrangement of the hoisting auxiliary block 2 can greatly reduce raw material purchase cost and processing manufacturing cost and shorten production period. The other key point is that the lifting ring screw hole 3 is machined after the template 1 and the lifting auxiliary block 2 are fixedly connected into an integral structure, so that the concentricity of the two sections of lifting ring screw holes 3 can be ensured, and further the reliable connection of the lifting rings is ensured. Moreover, it can be seen from the above structure that the auxiliary hoisting block 2 is fixed on the non-hoisting surface of the template 1, so that the auxiliary hoisting block 2 does not bear hoisting force directly, but the template 1 bears most of hoisting force, and the template 1 is directly connected with other parts of the die carrier, so that the connection strength is reliable, the potential safety hazard of hoisting is reduced, and the reliability of the hoisting structure is ensured.
It should be noted that the fixing connection structure of the hoisting auxiliary block 2 and the template 1 is various, and it is easy to think that the fixing is performed by welding. However, welding has the following drawbacks: the welding part affects the beauty, and more time and processing cost are required for repairing; in addition, once the welding part is stressed, the welding part is easy to fall off, and the re-welding is needed with high probability; the large-area welding can lead to the deformation of the template 1, the high temperature of welding can influence the molecular structure of the material, the uneven hardness of the material can be caused by welding, the internal stress of the template 1 can be increased due to the heat energy generated by welding, and the overall quality of a die blank is influenced.
Based on this, the hoisting auxiliary 2 and the formwork 1 are preferably fixedly connected by bolts 4 in this embodiment. The bolt 4 can realize the detachable connection of the hoisting auxiliary block 2, is convenient for install the hoisting auxiliary block 2 when the hoisting is needed, and can detach the hoisting auxiliary block 2 when the hoisting is not needed, so that the structure of the die carrier is simplified, and the applicability is higher.
Meanwhile, in design, the limiting groove 11 is formed in the template 1, the hoisting auxiliary block 2 is suitable for being embedded and fixed in the limiting groove 11, namely, the hoisting auxiliary block 2 is embedded into the end face of the template 1, so that the template 1 can limit the movement of the hoisting auxiliary block 2 in the horizontal direction, on one hand, dislocation of the hoisting ring screw holes 3 at two ends can be avoided or reduced, concentricity of the hoisting ring screw holes 3 is guaranteed, on the other hand, the hoisting auxiliary block 2 is guaranteed not to be broken or fall off due to external force, and therefore use safety is improved.
Based on the structure, a locating pin 5 is further arranged between the template 1 and the hoisting auxiliary block 2, and the locating pin 5 and the bolt 4 are arranged in the same direction. Positioning pins 5 are adopted for positioning, so that the situation that dislocation occurs between the lifting ring screw hole 3 in the lifting auxiliary block 2 and the lifting ring screw hole 3 on the template 1 due to machining errors, assembly tolerances and the like (namely, the lifting ring screw hole 3 is ensured to be always concentric) is avoided.
As shown in fig. 2, the specific assembly structure of the positioning pin 5 and the bolt 4 is as follows: the template 1 is provided with a threaded hole 12, the hoisting auxiliary block 2 is provided with a first through hole 21 in a penetrating way, and the bolt 4 is suitable for penetrating through the first through hole 21 and is connected in the threaded hole 12 in a threaded way, so that the template 1 and the hoisting auxiliary block 2 are fixedly connected; the end part of the first through hole 21 is also provided with a countersunk hole 211, and the tail end of the bolt 4 is countersunk in the countersunk hole 211; the template 1 is provided with a pin hole 13, the hoisting auxiliary block 2 is provided with a second through hole 22 in a penetrating way, and the positioning pin 5 is suitable for penetrating through the second through hole 22 and is connected in the pin hole 13 in an interference way, so that the positioning template 1 and the hoisting ring screw hole 3 on the hoisting auxiliary block 2 are concentric.
For processing convenience, when CNC processing is used, the lifting ring screw hole 3 or a bottom hole thereof generally directly penetrates through the lifting auxiliary block 2, the lifting auxiliary block 2 is fixedly provided with a foolproof cover plate 6, and the foolproof cover plate 6 is suitable for covering the lifting ring screw hole 3. On the non-hoisting surface, the fool-proof cover plate 6 is designed to cover the hanging ring screw hole 3, so that fool-proof is realized, links such as turning plates, transferring and the like are avoided for operators, and the hoisting work is carried out from the non-hoisting surface by mistake, so that the potential safety hazard is further reduced.
As shown in fig. 3 and 4, the lifting auxiliary block 2 has two types of round structures and square structures on the basis of standard structural design, so that interference and the like caused by insufficient design space can be avoided, and the die design is more flexible. Based on the above shape, the hanging ring screw hole 3 is preferably opened at the center of the auxiliary hoisting block 2.
As can also be seen from fig. 3 and 4, in this embodiment, four bolts 4 are provided and are regularly and uniformly distributed on the lifting auxiliary block 2, and two positioning pins 5 are provided and are uniformly distributed between the two bolts 4.
As shown in fig. 5 to 10, the application also provides a processing method of the die blank hoisting structure, which mainly comprises the following five steps:
step one: forming a template 1 shown in fig. 5;
step two: forming a hoisting auxiliary block 2 shown in fig. 6;
step three: as shown in fig. 7, the auxiliary hoisting block 2 is fixedly installed on the template 1;
step four: machining a lifting ring screw hole 3 shown in fig. 8 from the plane of the template 1 and extending into the lifting auxiliary block 2;
step five: a foolproof cover plate 6 shown in fig. 9 is fixed on the hoisting auxiliary block 2, and the foolproof cover plate 6 covers the hoisting ring screw hole 3.
As shown in fig. 5, the first step specifically includes: a limiting groove 11 is processed on the template 1; threaded holes 12 and pin holes 13 are machined in the form 1.
As shown in fig. 6, the second step specifically includes: a first through hole 21 and a second through hole 22 are processed on the lifting auxiliary block 2.
As shown in fig. 7, the third step specifically includes: the hoisting auxiliary block 2 is embedded in the limit groove 11 for fixed installation; threading the bolt 4 through the first through hole 21 and into the threaded hole 12; the locating pin 5 is passed through the second through hole 22 and is interference-connected in the pin hole 13.
The fixing manner of the fool-proof cover plate 6 in the fifth step includes, but is not limited to, one or more of welding, bonding, clamping, screw connection and magnetic connection.
As a perfection, the processing method further comprises a quality inspection step, specifically as shown in fig. 10: detecting whether the fixed installation of the hoisting auxiliary block 2 and the template 1 is qualified or not after the step three; detecting whether the hanging ring screw hole 3 is qualified or not after the fourth step; and step five, checking whether the die blank hoisting structure is qualified or not.
The processing method of the die blank hoisting structure of the application sets the following processing parameters besides the processing steps:
as shown in fig. 8, the thickness of the machined template 1 is D, the thickness of the machined hoisting auxiliary block 2 is H, the length of a hoisting ring screw hole on the template 1 is L1, and the length of a hoisting ring screw hole on the hoisting auxiliary block 2 is L2; wherein D is less than H, and L1 is less than L2. In this example, d=70 mm, h=85 mm, l1=60 mm, l2=68 mm. Obviously, in order to ensure the hoisting safety, the screwing length of the hoisting ring, namely the length of the hoisting ring screw hole 3, needs to be enough. The length of the lifting ring screw hole 3 depends on the sum of the thicknesses of the template 1 and the lifting auxiliary block 2, and the template 1 is larger in area, and the increase of the thickness greatly increases the manufacturing cost, so that the embodiment preferably increases the thickness of the lifting auxiliary block 2 with smaller area, and reduces the overall manufacturing cost of the die carrier on the premise of ensuring the screwing length of the lifting ring.
As shown in fig. 8, the depth of the processed limit groove 11 is E; wherein D/20 < E < D/5, and E is more than or equal to 2mm. E=10 mm in this example. It is expected that the thickness of the connecting part of the template 1 is reduced due to the fact that the limiting groove 11 is too deep, the overall strength of the template 1 is further reduced, the limiting groove 11 cannot play a limiting role due to the fact that the lifting auxiliary block 2 is easy to fall off due to external force. Therefore, the depth E of the limiting groove 11 is positively correlated with the thickness D of the template 1, and a reasonable proportional relationship and a minimum value of the depth E are set, so that the limiting effect of the limiting groove 11 is realized on the premise of ensuring the strength of the template 1.
As shown in fig. 8, the minimum width of the machined hoisting auxiliary block 2 is W, and the nominal diameter of the machined hoisting ring screw hole 3 is M; wherein M is more than 2 and less than W is more than 3 and less than H is more than 2. W=148 mm, m=64 mm in this example. In this embodiment, the hoisting auxiliary 2 is circular or square, so W is a circular diameter or square side length; the main purpose of setting the minimum width W to at least twice the nominal diameter M is to reserve enough space for the mounting bolts 4 and the locating pins 5 to avoid tearing at the first and second through holes 21, 22 due to the too small thickness. Of course, too large a minimum width W may aggravate the lifting auxiliary block 2 and may increase manufacturing costs. According to the international standard "eye screw GB 825-88", it can be inquired that the length of the thread section of the eye is generally twice the nominal diameter thereof, so that the overall length of the eye screw hole 3 designed in this embodiment is l1+l2=128 mm, which is twice the nominal diameter M thereof, that is, l1+l2=2m, and by combining the above parameters, L1 < L2 is set, and H > L2 is known, and H > M and H < 2·m are deduced. It is foreseen that the majority of the lifting force is taken up by the formwork 1, so L1 is not too small, and in this embodiment L2 is preferably set to be slightly larger than L1 (l1=60 mm, l2=68 mm being a reasonable value).
Due to machining errors and assembly tolerances, certain dislocation can occur to more or less in the lifting ring screw hole 3 in the using process, in order to control the dislocation of the lifting ring screw hole 3 within an acceptable range, the matching precision between the lifting auxiliary block 2 and the limiting groove 11 needs to be improved, and for this reason, the matching between the lifting auxiliary block 2 and the limiting groove 11 is equivalent to shaft hole matching, and the matching clearance between the lifting auxiliary block 2 and the limiting groove 11 is K (can be regarded as non-standard matching tolerance set by people); the matching of the hanging ring screw hole 3 and the hanging ring is equivalent to shaft hole matching, and the limit matching clearance between the hanging ring screw hole 3 and the hanging ring is J; wherein K is less than or equal to J, and K and J are positively correlated. It should be noted that the conventional screw hole and bolt have a large tolerance range, and the misalignment of the screw hole is not considered, so that the tolerance for defining the fit clearance K is not suitable as the embodiment. As a referent object, in this embodiment, the matching between the lifting ring screw hole 3 and the lifting ring is equivalent to shaft hole matching, the nominal diameter m=64 mm of the lifting ring screw hole 3 is known, the common matching precision grade 6H of common threads is selected, and according to national standard tolerance grade and limit deviation table GB/T1801-1999 of holes and shafts, the on-shaft tolerance of 64mm is found to be 0, the lower tolerance is-0.019 mm, the on-hole tolerance of 64mm is +0.019mm, and the lower tolerance is 0; taking the minimum value of the shaft to 64-0.019= 63.981mm, taking the maximum value of the hole to 64+0.019= 64.019mm, and obtaining the limit fit clearance between the two to be J= 64.019-63.981 =0.038 mm. With the J value as a reference, setting the K value, in this embodiment, setting k=0.02 mm, that is, controlling the fit tolerance of the hoisting auxiliary block 2 and the limit groove 11 to be within 0.02mm, so as to meet the design requirement.
The die blank hoisting structure formed by the processing method has the following advantages:
(1) Through repeated experiments, the use safety of the hoisting auxiliary block meets the design requirement; the lifting auxiliary block is embedded into the template, is fixed by bolts, is additionally positioned by positioning pins, achieves the effect consistent with direct welding in use performance, has no welding defect, and is convenient to detach and replace in the use process. In summary, compared with the traditional structure, the use safety is improved by about 50%;
(2) Compared with the traditional design and processing, the template adopts a novel hoisting auxiliary block structure, and the production period is shortened by 25-30%;

It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present application, and various changes and modifications may be made therein without departing from the spirit and scope of the application, which is defined by the appended claims.
