Description

Shaping flanging-preventing unloading mechanism used in pliers head machining process
Technical Field
The invention belongs to the field of hardware tool manufacturing, relates to machining equipment of pliers, and particularly relates to a shaping flanging-preventing unloading mechanism used in a pliers head machining process.
Background
Pliers are hardware tools with very wide application, and the pliers head part on the pliers is a main working element of the pliers and is used for cutting wires, iron wires or iron sheets and the like. The forceps head function area generally comprises the following elements: as shown in fig. 1-2, the forceps body 80 consists of two halves which are symmetrical in left-right center and respectively comprise a forceps head 81 and a forceps handle 82; the pliers head 81 is provided with an outer edge 802, an inner edge 803, and a square opening 804 for shearing, and a grinding disk 801 for assembling.
In the existing pliers head processing technology, when pliers are manufactured, the four elements on the pliers head are respectively completed by two working procedures in eight processing stations, and the left pliers body is clamped four times and the four processing stations are formed; the right clamp body is clamped four times and four processing stations are arranged; in addition, the prior art is mostly manually clamped, so that the production efficiency is low, and the labor intensity is high.
The reason is that the existing pliers are generally piled together in a mixed mode after blank forming due to the fact that the structure is complex, the blanks are not piled in rows in sequence, part of time is wasted in machining and finding materials, and automatic machining and feeding cannot be achieved due to inconsistent feeding.
Applicant has disclosed in a prior application a gravity feed rail for automatic sequencing of the caliper body as shown in fig. 6, the rail being located on either side of the grinding disc position of the caliper body by the distance between two columnar rails, one columnar rail being located on the end of the caliper head remote from the grinding disc and the other columnar rail being located on the end of the caliper handle near the grinding disc, i.e. the rail as shown in the figure is located at the middle end 822 of the caliper handle (i.e. at the middle circular arc of the caliper handle); the structure utilizes the self gravity of the pliers heads to realize the automatic overturning and positioning of the pliers body.
However, in actual use, the positioning component is required to be reused for fixing the pliers body, and in the pushing and moving process, the possibility of deviation with a certain probability exists (the deviation probability is 1-5 per mill), so that the automatic feeding and processing are not facilitated; in addition, in the process that the push plate pushes forward and falls to another platform, the pliers body standing on the upper side of the guide rail in the prior art has the falling state shown as an A state in fig. 9 (i.e. the millstone hole faces the bottom surface), if the pliers body is not turned over in the falling process, namely shown as a B state in fig. 9 (i.e. the millstone hole faces upwards), the pliers body is convenient for subsequent process processing, and the prior guide rail technology cannot be realized, so that another set of system is needed for processing operation.
For mature hardware tools, the selling price is low, and how to improve the processing technology, improve the product quality and reduce the processing cost is an important goal of all processing manufacturers. The invention mainly provides a novel processing tool, which is convenient for arranging clamp bodies in a row order, reduces processing procedures, provides technical support for efficient production and is convenient for subsequent automatic processing and feeding.

Detailed Description
In order that those skilled in the art may better understand the technical solutions of the present invention, the following detailed description of the present invention with reference to the accompanying drawings is provided for exemplary and explanatory purposes only and should not be construed as limiting the scope of the present invention.
As shown in fig. 3 to 5, the specific structure of the present invention is: the shaping flanging-preventing unloading mechanism comprises a first layer of platform 1 and a movable push plate 3 horizontally reciprocating on the first layer of platform 1, wherein three columnar guide rails are arranged between the first layer of platform 1 and the movable push plate 3, and the columnar guide rails are fixed on the first layer of platform 1 at parallel intervals and are parallel to the movement direction of the movable push plate 3; a striker plate 7 perpendicular to the columnar guide rail is arranged at the front end of the first layer of platform 1, and a blanking gap 9 is reserved between the striker plate 7 and the first layer of platform 1; the lower side of the blanking gap 9 is provided with a second layer of platform 4 and a slow bearing inclined plane 6 for sliding materials and avoiding overturning is arranged on the blanking gap 9. Therefore, the turnover phenomenon of the pliers in the process of falling to the next layer is avoided, and the machining error phenomenon is avoided.
The working position of the baffle plate 7 is used for limiting the forward overturning of the clamp body when the materials fall from the blanking gap 9, namely the state A in figure 9 is avoided.
Preferably, the slow bearing inclined surface 6 is formed by a plurality of inclined surface guide rails 601 at intervals in parallel, and the horizontal projection is parallel to the push plate; the bevel angle of the bevel rail 601 is 30-70.
Preferably, the bevel angle of the bevel rail 601 is 35 °, and the top bevel of the bevel rail 601 is lower than the first platform 1. At this angle, the pliers drop down to reach the slow-bearing inclined surface 6, and then the blanking is not turned over.
Preferably, the blanking gap 9 is 1-1.5 pliers body widths.
Preferably, the positional relationship of the three columnar guide rails on the first platform 1 is as follows: the first cylindrical rail 201 is at the end of the forceps head 81 remote from the grinding wheel 801, the second cylindrical rail 202 is at the forceps head end face 811 on the other side of the forceps head grinding wheel aperture, and the third cylindrical rail 203 is at the middle circular arc where the forceps handle middle end 822 is located.
Preferably, side plates 5 are disposed on both sides of the first platform 1 and the second platform 4.
Preferably, the striker plate 7 is movably arranged at the front end of the first layer of platform 1, and is connected with a driving component for driving the striker plate to move up and down, and the striker plate enters a working position according to processing requirements.
When the pliers are particularly used, the pliers body 80 is turned over under the action of gravity concentrated at the gravity center of the grinding disc of the pliers head, so that the purpose of automatic sequencing of the pliers is achieved, labor is saved, and the pliers are efficient and convenient.
The material baffle 7 is movably arranged at the front end of the first layer of platform 1 and is connected with a driving component for driving the material baffle to move up and down, and the material baffle enters a working position according to processing requirements; in order to facilitate the realization of flanging operation of the forceps body when necessary, the baffle plate 7 is lifted, so that the automatic flanging and discharging of the forceps can be realized;
when the pliers body is moved forward to the next layer without overturning, namely, the material is discharged in the state B in fig. 9, the lower baffle plate 7 is driven, and then the movable push plate 3 pushes the pliers body 80 on the guide rail to move forward; the pliers body 80 naturally turns forward due to the gravity of the pliers body 80 (i.e., there is a trend of the state a in fig. 9), but at this time, the upper front part of the pliers body 80 is blocked by the baffle plate 7, then falls down from the blanking gap 9 onto the slow bearing inclined surface 6 of the second platform 4 due to the gravity, and then slides down from the inclined surface to form the state B in fig. 9, thereby completing the overturn-preventing blanking operation.
The slow bearing inclined plane 6 in fig. 10 is composed of a plurality of inclined plane guide rails 601 at intervals in parallel, and the horizontal projection is parallel to the push plate; the inclined angle of the inclined guide rail 601 is preferably 35 degrees, so that the clamp body 80 is prevented from bouncing and overturning when falling down; if the bevel angle is too shallow, the clamp body 80 cannot slide down to the next station effectively.
The gravity self-return ordering structure is convenient for the clamp body to move to be completely consistent, and is clamped and processed with the subsequent process.
