Противник 14 вместе с перемычкой удаляется и освобождается, от последней. Удаляется поковка из правочной матрицы 13 и облой с обрезной матрицы 12. Противник 14 устанавливается в рабочее положение и цикл повторяется, снова.The enemy 14, together with the jumper, is removed and freed from the latter. The forging is removed from the dressing matrix 13 and the overburden from the trim matrix 12. The opponent 14 is set to its working position and the cycle repeats again.

Выемка на нижней плите 1, в условиях постоянно ссыпающейся с поковокThe notch on the bottom plate 1, in conditions constantly poured from forgings

Пуансон 10 посредством клина 11 закреплен на верхней плите. Обрезная матрица 12 закреплена на подвижной траверсу а правочная матрица 13 — на нижней плите.The punch 10 by means of the wedge 11 is mounted on the upper plate. The trimming matrix 12 is mounted on a movable crosshead and the dressing matrix 13 is mounted on the bottom plate.

Противник 14 установлен на правочную матрицу, снабжен цилиндрическим штифтом 15 и фиксируется конусной оправкой 6 с торцовым пазом, жестко связанной с нижней плитой штампа.The enemy 14 is mounted on the straightening matrix, equipped with a cylindrical pin 15 and fixed with a conical mandrel 6 with an end groove rigidly connected to the bottom plate of the stamp.

В верхнем положении ползуна пресса (фиг. 2) траверса 3 поднята тягами 8 и не связана с нижней плитой 1. На обрезную матрицу 12 укладывается обрезаемая поковка и включается пресс, при ходе ползуна вниз траверса 3 опускается вниз до тех пор, пока не ляжет на опорные поверхности нижней плиты 1. При этом конусные пальцы 5 посредством запрессованных в траверсу 3 втулок 7 с коническими отверстиями ловят и фиксируют положение обрезной матрицы 12 относительно нижней плиты 1, т.е. относительно противника 14 и правочной матрицы 13. Продолжающая опускаться вниз верхняя плита 2 посредством втулок входит в сопряжение с направляющими колонками 4, фиксирующими положение пуансона 10 относительно обрезной 12 и правочной 13 матриц и противника 14. Дальнейшим ходом вниз пуансон 10 продавливает поковку через обрезную матрицу 12 и противник 14, осуществляя правку на правочной матрице 13 в конце рабочего хода пресса.In the upper position of the press slider (Fig. 2), the crosshead 3 is raised by rods 8 and is not connected with the lower plate 1. The cut forging is laid on the cut matrix 12 and the press is turned on, when the slider moves downward, the crosshead 3 is lowered down until it rests on the supporting surfaces of the lower plate 1. In this case, the conical fingers 5, by means of the bushings 3 pressed into the crosshead 3, with conical holes, catch and fix the position of the edging matrix 12 relative to the lower plate 1, i.e. relative to the opponent 14 and the straightening die 13. The upper plate 2, which continues to sink downwards, is coupled by means of bushings to the guiding columns 4, fixing the position of the punch 10 relative to the edged 12 and the right 13 dies and the opponent 14. The further stroke down the punch 10 pushes the forging through the cutting die 12 and the adversary 14, making corrections on the editing matrix 13 at the end of the press stroke.

При ходе ползуна вверх траверса 3 поднимается тягами 8 вверх, в исходное положение, а поковка остается на правочной матрице 13. При этом перемычка остается на противнике 14, а срезанный облой — на обрезной матрице 12. Послед— окалины и случайных обечаек, предохраняет траверсу 3 от перекоса в рабочем 15 положений.When the slider moves up, crosshead 3 is lifted by rods 8 up to its original position, and the forging remains on the straightening die 13. At the same time, the jumper remains on the opponent 14, and the cut-off gusset remains on the cutting die 12. The last — dross and random shells, protects the crossarm 3 from skew in the working 15 provisions.

Предложенный штамп обладает высокой надежностью работы и удобством обслуживания.The proposed stamp has high reliability and ease of maintenance.

Claims

The invention relates to the processing of metals by pressure, namely, to designs of stamps of a combined action. A stamp of combined action is known, comprising upper and lower stamps, an adversary punch, as well as an IL cutter matrix. The specified stamp does not provide the necessary quality of work in relation to operational properties. Also known is a combined action stamp for trimming, flashing, and forging, containing a lower plate with a firmware installed on it, an upper plate with a trimmed punch attached to it, a traverse connected to the upper plate, and a trimmed and straightening matrix 2 The disadvantage of this stamp is the low reliability and inconvenience of service. The purpose of the proposal is to eliminate these drawbacks, namely increasing the reliability of operation and ease of maintenance. This goal is achieved by the fact that the bottom plate is made with a notch under the scale, the right-hand matrix is rigidly mounted on the bottom plate, the enemy is installed on the right-hand matrix and has a blind conical hole and a cylindrical pin installed in the conical hole perpendicular to its axis, and the bottom plate it is provided with a mandrel fixed with a mandrel with a tapered working part for the enemy’s hole, while at the end of the tapered part of the mandrel there is a groove for the cylindrical pin of the opponent. FIG. Figure 1 shows the combined action stamp (without the top plate), top view; in fig. 2 is the same, section A-A in FIG. one; in fig. 3 - installation unit of the enemy, node G in FIG. 2; in fig. 4 is the same section BB in FIG. 3. The stamp has a lower plate I, an upper plate 2 and a movable yoke 3. In the lower plate, guide columns 4, tapered pins 5 and a taper mandrel are respectively pressed in. The sleeves 7 with tapered holes are pressed into the yoke connected by means of t g 8 and locknut 9 with the top plate. The sleeves pressed into the upper plate, with which the guide columns of the lower plate mate, are conditionally not until Panson 10 is fixed to the upper plate by means of a wedge II. The matrix 12 is mounted on a movable cross-member, and the matrix 13 on the lower one. The collar 14 is mounted on a matrix, fitted with a cylindrical pin 15 and fixed with a tapered mandrel 6c with a mechanical groove rigidly connected to the lower stamp plate. In the upper position of the press ram (Fig. 2), the yoke 3 is lifted by the rods 8 and is not connected to the bottom plate 1. A trimming set is placed on the trimming matrix 12 and the press is turned on, while the yoke goes down, until it rests on the supporting surfaces of the bottom plate 1. In this case, the tapered pins 5, by means of 3 sleeves 7 with conical holes pressed into the yoke, catch and fix the position of the cutting matrix 12 relative to the bottom plate 1, i.e. with respect to the enemy 14 and the adjusting matrix 13. Continuing to descend the top plate 2 by means of sleeves, it mates with guide columns 4, fixing the position of the punch 10 relative to the trimmed 12 and correcting 13 matrices and the enemy 14. Further down, the punch 1O pushes the forging through the trimmed Matrix 12 and Proshivnik 14, carried out the editing on the editing matrix 13 at the end of the working stroke of the press. When the slider moves upward, the traverse 3 rises up with the gambles 8 up, to the initial position, and the forging remains on the adjusting matrix 13. At the same time, the jumper remains on the opponent 14, and the cut-off burr - on the trimmed matrix 12. The last achieved due to the size of the gap between the punch and the die, the stitcher 14, together with the web, is removed and released from the latter. The forging is removed from the adjusting matrix 13 and the edge from the trimming matrix 12. Proshnik 14 is set to the working position and the cycle is repeated. again. The notch on the bottom plate 1, under conditions of constant descaling from the forgings of scale and accidental shells, prevents the yoke 3 from being skewed into the working positions. The proposed stamp has a high reliability of operation and ease of maintenance. Claims of the Invention Combined action stamp for trimming around, cutting and stitching, containing a ning plate with an opponent mounted on it, an upper plate with a trimmed punch attached to it, a traverse connected to the top plate, and also a cut and right matrix, characterized in that, in order to increase reliability and ease of maintenance, the bottom plate is made with a notch under the scale, the right matrix is rigidly mounted on the bottom plate, the enemy is installed on the right matrix and is made with a tapered bore and a cylindrical pin installed perpendicular to its axis in a tapered bore, and the bottom plate is equipped with a mandrel with a tapered working part for the enemy’s hole fixed on the opponent’s axis, and the cylindrical pin of the opponent is grooved at the end of the cone.
