Description

(54) LOADING DEVICE

one

The invention relates to welding, more precisely to combined devices in which assembly and welding devices for relief welding of brake pads are combined.

A combined welding device is known, which comprises an upper roller with a pressure pneumatic cylinder, a clamping device, a clamping drive of the clamping mechanism, a rim feed magazine, a rib feeder with rib loading mechanisms 1.

The accumulation of the package of ribs and its correct installation is made in advance in a special bunker, hinged to the device body. With the help of a pneumatic cylinder, the hopper is rotated around an axis and pushed into the bag into the feeder magazine. The ribs from the magazine are fed to the clamping mechanism by means of pneumatic pusher. During movement in the magazine-pusher of the package, the ribs are held in the desired position by means of a pressure guide chute or magnetic plate.

However, in this device, when transferring a packet of ribs from a bunker to a hopper, individual ribs may be displaced from the original oriented position. As a result of this displacement, when the rib is fed into the clamping mechanism, the rib is jammed due to its non-penetration into the clamping surface of the clamping mechanism.

The closest to the proposed technical entity is a boot device containing a horizontal magazine with forced movement of workpieces by a drive pusher installed with the possibility of taking out of the store when loading the next batch of workpieces 2

The disadvantage of this device is the offset of the oriented position of the blanks during the loading process and the instability of the position of the blanks.

The purpose of the invention is to improve the reliability of the device and performance.

Claims (2)

This is achieved by the fact that the described device is equipped with an additional drive pusher of the next batch of workpieces installed parallel to the main pusher in the direction of movement of the workpieces, the working surface of which is made inclined in the direction opposite to the direction of non-movement of the workpieces at an angle to the vertical, greater friction angle. The horizontal magazine is provided with guides with base surfaces for precise orientation of the blanks. FIG. 1 shows the described device; in fig. 2 is the same, view along arrow A in FIG. in fig. 3 shows a section BB in FIG. one; in fig. 4 - sketch of brake pads in two projects. The device comprises a housing, the front side of which is mounted with a drive 2 of compression with upper welding rollers and a clamping device 3. On the right side of the housing 1 a rotational drive of the clamping device 4 is installed. On the upper part of the housing 1 a feeder 5 of rims is mounted. On the lower part of the housing 1, there are mechanisms 6 for feeding ribs, two horizontal magazines 7 with ribs, driving pushers 8 for a package of ribs and additional driving pushers for 9 edges with pneumatic cylinders. Shops 7 ribs are equipped with hardened guides 11 and 12. The working surface of the additional pusher 9 of the packet of ribs is inclined in the direction opposite to the direction of movement of the bag, at an angle a, greater friction angle. The brake pad has two ribs 13 and a rim 14, so the car has two similar mechanisms for loading and feeding ribs. The operation of the device is as follows. From the magazines 7, one rib is fed to the rib feeder 6, which at a certain moment delivers a pair of ribs to a continuously rotating clamping device 3. At the same time, one rim is fed from the top 5 rim feeder to the upper welding rollers. With further rotation of the clamping device 3, the compression drive 2 lowers the upper welding rollers onto the rim, then, according to a given program, the welding current is periodically turned on and the rim is bending and welding simultaneously with the ribs. During operation of the device in an automatic cycle, the operator manually sets the ribs 13 into the guides 11 and 12 of the magazine 7 with the extreme right position of the additional pusher 9. When reducing the number of ribs between the pusher 8 and the clamping device 3, the pusher 9 is left to the left as far as the ribs to the pusher 8. After that, the pneumatic cylinder 10 of the rotation of the pusher 8 rotates it around its axis from the position I to the position AND, disengages from the ribs. Then the pusher 8 moves to the extreme right position, BiiOBb turns to the position 1 and is fed to the left until it stops in the loaded bag, and the pusher 9 is retracted to the right (initial position). The store is ready for a new package of ribs. The use of guides in the pusher stores that form the base surfaces improves the reliability of the orientation of the ribs, the presence of an additional device increases the productivity of labor, and the front surface of the pusher of the ribs, inclined in the direction opposite to the direction of the package, angles to the vertical at a greater angle friction, allows you to maintain a stable position of the ribs during their movement without the use of special clamping devices. Claim 1. A loading device, mainly to a machine for contact relief welding of brake pads, comprising a horizontal magazine with forced movement of workpieces by a driving pusher installed with the possibility of taking out the next batch of workpieces from the store, in order to increase the reliability of the device and performance, the device is equipped with an additional drive pusher 1 regular batch of workpieces installed parallel to the main pusher and moving them toward preforms working surface which is inclined in the direction opposite to the direction of movement of the preforms to the vertical at an angle greater than the angle of friction. 2. A device according to claim 1, characterized in that the horizontal magazine is provided with guides with base surfaces for precise orientation of the blanks.
